A systematic review of environmental correlates of obesity-related dietary behaviors in youth

Population trajectories and age-dependent associations of obesity risk factors with body mass index from childhood to adolescence across European regions: A two-cohort study

OBJECTIVE

To investigate population trajectories of behavioural risk factors of obesity from childhood to adolescence and their associations with body mass index (BMI) in children across European regions.

METHODS

Data were harmonised between the European multi-centre IDEFICS/I.Family and the Amsterdam Born Children and their Development Cohort. Participants were aged 2.0-9.9 and 5.0-7.5 years at baseline, respectively, and were followed until age 18 years. Behavioural risk factors of interest included diet, physical activity, media use and sleep. Mixed effects models were used for statistical analyses to account for repeated measurements taken from the same child.

RESULTS

The study included a total of 14 328 individuals: 4114, 4582, 3220 and 2412 participants from Northern, Southern, Eastern Europe and Amsterdam, respectively. Risk factor means and prevalences changed with age, but the trajectories were mostly similar across regions. Almost no associations between behavioural factors and BMI were found at the age of 6 years. At 11 years, daily sugar-sweetened foods consumption, use of active transport, sports club membership and longer nocturnal sleep duration were negatively associated with BMI in most regions; positive associations were found with media use. Most associations at 11 years of age persisted to 15 years.

CONCLUSIONS

Whilst population trajectories of media use and nocturnal sleep duration are similar across European regions, those of other behavioural risk factors like active transport and daily vegetable consumption differ. Also, associations between behavioural risk factors and BMI become stronger with age and show similar patterns across regions.

Mediators and moderators of the effects of a school-based intervention on adolescents' fruit and vegetable consumption: the HEIA study

OBJECTIVE

To examine whether targeted determinants mediated the effects of the HEalth In Adolescents (HEIA) intervention on fruit and vegetable (FV) consumption and explore if these mediating effects were moderated by sex, parental education or weight status.

DESIGN

Cluster-randomised controlled trial.

SETTING

The HEIA study (2007-2009) was a Norwegian 20-month multi-component school-based intervention to promote healthy weight development. FV consumption and targeted determinants were self-reported at baseline, mid-way (8 months) and post-intervention (20 months).

PARTICIPANTS

Adolescents (11-13-year-old) in twenty-five control schools (n 746) and twelve intervention schools (n 375).

RESULTS

At post-intervention, more adolescents in the intervention group compared with the control group had knowledge of the FV recommendations (OR: 1·4, 95 % CI 1·1, 1·9) and reported a decreased availability of vegetables at home (β: -0·1, 95 % CI -0·2, 0·0). Availability/accessibility of FV at home, availability of vegetables at dinner, taste preferences for different types of FV and knowledge of the FV recommendations were positively associated with the consumption of FV. However, none of the post-intervention determinants significantly mediated the intervention effects on FV consumption. Although no moderating influences by sex, parental education or weights status were observed on the mediating effects, exploratory analyses revealed significant moderations in the b-paths.

CONCLUSIONS

Since none of the targeted determinants could explain the increase in FV consumption, it remains unclear why the intervention was effective. Reporting on a wide range of mediators and moderators in school-based interventions is needed to reveal the pathways through which intervention effects are achieved.

The feasibility, acceptability and potential efficacy of a parental text message and social media program on children's vegetable consumption and movement behaviours: A pilot randomised controlled trial

ISSUE ADDRESSED

Australian children fall short of meeting the dietary, physical activity and sedentary behaviour guidelines. This study aimed to test the feasibility, acceptability and potential efficacy of a parental text message and social media program on, primarily, their school-aged children's vegetable consumption and movement behaviours, and, secondarily, their own.

METHODS

Between August and November 2022, we conducted a two-armed randomised controlled trial with 242 parents/caregivers of primary school-aged children in New South Wales. The 'Adventure & Veg' intervention ran for 8 weeks, promoting vegetable eating behaviours, local outdoor physical activity opportunities and ideas for reducing screen time. Feasibility and acceptability were assessed via recruitment and retention data, intervention metrics and self-reported participant data. Vegetable intake and movement behaviour data were collected via online-surveys and effect sizes were examined.

RESULTS

Most participants reported that they enjoyed receiving the text messages (88%) and the delivery frequency was acceptable (94%). Limitations to Facebook as a delivery platform were reported. The majority of participants used the text messages to influence the vegetable eating (65%) and movement (77%) behaviours of their child. Significant effects were observed among intervention child participants compared with control for mean daily vegetable consumption (0.45 serves, CI: .19; .71, p = .001, d = .5); weekly vegetable variety (1.85, CI: .25; 3.45, p < .001, d = .6); and weekly physical activity variety (.64 CI: .09; 1.19, p = .022, d = .3). Parents in the intervention group increased their daily vegetable intake by .44 serves (CI: .11; .78, p = .01, d = .4).

CONCLUSIONS

A parental text message and social media program has potential to support children's vegetable intake and movement behaviours. Further research is required to explore different online delivery methods to promote local outdoor activity options. SO WHAT?: The Adventure & Veg program holds promise as a stand-alone health promotion intervention or as a useful adjunct to current family or school-based healthy lifestyle programs.

Using Non-Violent Discipline Tools: Evidence Suggesting the Importance of Attunement

Training in non-violent discipline is important to prevent violence against children and ensure that their caregivers remain a safe base for them. This paper aims to deepen understanding of non-violent discipline by exploring attunement as a mechanism in the effectiveness of non-violent discipline tools. Attunement describes the sensitive responsiveness of caregivers towards their children and has been found to be central to the formation of secure attachment bonds and development of self-regulation. It includes understanding or being "in tune with" the child's needs and signals, matching these with appropriate responses. The objective of this paper is to explore attunement in relation to non-violent discipline. Peer-reviewed systematic reviews previously included in a systematic overview of evidence on non-violent discipline options were screened for information relevant to attunement. All reviews were published in English between 1999 and 2018 and offered evidence on at least one non-violent discipline tool. Although no reviews explicitly addressed attunement, evidence was found suggesting its importance in the use and effectiveness of discipline methods. Research directly investigating attunement in discipline is needed.

Only the best for my kids: An extended TPB model to understand mothers' use of food labels

Despite the evidence that mothers' food purchasing behavior impacts the quality of children's diet, few studies have explored psycho-social factors influencing how mothers choose the food to buy for their children. To fill this gap, this study tested an extended Theory of Planned Behavior (TPB) model to predict mothers' tendency to seek information on food labels before purchasing food for children. Participants included 311 Italian mothers who completed a self-report questionnaire measuring their information-seeking behavior, TPB variables, anticipated regret and healthy-eater identity. Results from a Multiple Correspondence Analysis showed that mothers' information-seeking behavior involved a continuum of choices ranging from selecting conventional or prepackaged foods to choosing to read the food label before making a purchase. Besides, a Partial Least Squares-Structural Equation Modeling analysis showed that information-seeking behavior was positively predicted by intention (β = 0.309, p < 0.001) and healthy-eater identity (β = 0.195, p < 0.001). In turn, intention was positively affected by attitude (β = 0.208, p < 0.001), subjective norms (β = 0.155, p < 0.01), perceived behavioral control (β = 0.124, p < 0.05), anticipated regret (β = 0.193, p < 0.001), and healthy-eater identity (β = 0.191, p < 0.001). These findings emphasize that future initiatives could usefully target attitude, anticipated regret and self-identity to encourage mothers' informed food choices for their children.

Association of household composition with dietary patterns among adolescents in Brazil

The present study identified dietary patterns (DP) and analyse their association with household composition. This is a cross-sectional school-based study, with a nationally representative sample of Brazilian adolescent students, aged 11-19 years, with data from National School Health Survey (n 102 072). Food consumption was obtained through the weekly frequency of consumption of food markers, and the confirmatory factor analysis was applied to examine the latent variables 'Healthy' (beans, legumes/vegetables and fresh fruit/fruit salad) and 'Unhealthy' (ultra-processed foods, sweets, soft drinks and snacks) DP. The association between household composition and DP was estimated considering lives with both parents as reference category. Among adolescents aged 11-14 years, adherence to healthy DP was lower for boys who lived only with mother (β = -2·1), and boys (β = -4·9) and girls (β = -4·5) who lived without any parents. Adherence to unhealthy DP was higher among boys (β = 7·6) and girls (β = 6·0) who lived only with mother, and boys (β = 4·6) and girls (β = 5·3) who lived only with father. For older adolescents (aged 15-19 years), adherence to the unhealthy DP was higher among boys who lived only with mother (β = 3·9) or only with father (β = 5·3) and girls who lived only with mother (β = 6·3). Adherence to healthy DP was lower among girls who lived only with father (β = -9·0). Thus, adolescents who lived in single-parent households had lower adherence to healthy DP and greater adherence to unhealthy DP. Among younger adolescents of both sexes, living without any parent contributed to lower adherence to healthy DP.

Associations between parental and pre-adolescents' physical activity and diet quality: The role of parental child care involvement and child's sex

BACKGROUND

Research has demonstrated the importance of the family environment in the eating and activity levels of offspring. We examined the cross-sectional associations between moderate-to-vigorous physical activity (MVPA) and diet quality of parents and the MVPA and diet quality of pre-adolescents. Interactions were tested to assess whether the child's sex and the parental level of involvement in daily child care moderated these associations.

METHODS

Data from 2467 pre-adolescents (age 11.5 ± 0.2 years; collected in 2015-2016) and their parents or caregivers from a large-scale prospective birth cohort study in Amsterdam (ABCD-study) was used. Parents and pre-adolescents individually reported their diet quality and physical activity. Child care involvement was assessed using the Caregiver Child Interaction Scale. With hierarchical linear regression analyses, we assessed the independent contribution of fathers and mothers.

RESULTS

An association between mother-child MVPA was found (β = 0.013; 95 % CI: 0.006;0.021). The association between father-child MVPA was only significant for highly involved fathers (β = 0.014; 95 % CI: 0.004;0.023). The child's sex did not change these MVPA associations. Regarding diet quality, associations were found between mother-child diet quality score (DQS) (β = 0.254; 95 % CI: 0.192;0.316) and father-child DQS, with stronger associations between fathers and sons (β = 0.234; 95 % CI: 0.169;0.298) than between fathers and daughters (β = 0.114; 95 % CI: 0.047;0.181). Parental levels of involvement did not change these associations.

CONCLUSION

These findings demonstrate that both parental behaviours represent an important factor in physical activity and diet quality in pre-adolescents in a sex-specific manner. As such, it is essential to include both parents in research to obtain the necessary insights for developing effective interventions to promote children's healthy eating and physical activity behaviours.

Home-based cooking intervention with a smartphone app to improve eating behaviors in children aged 7-9 years: a feasibility study

Objective

To develop and evaluate the feasibility of a mobile application in Swiss households and assess its impact on dietary behavior and food acceptability between children who cooked with limited parental support (intervention group) with children who were not involved in cooking (control group).

Methods

A ten-week randomized controlled trial was conducted online in 2020. Parents were given access to a mobile-app with ten recipes. Each recipe emphasized one of two generally disliked foods (Brussels sprouts or whole-meal pasta). Parents photographed and weighed the food components from the child's plate and reported whether their child liked the meal and target food. The main outcome measures were target food intake and acceptability analyzed through descriptive analysis for pre-post changes.

Results

Of 24 parents who completed the baseline questionnaires, 18 parents and their children (median age: 8 years) completed the evaluation phase. Mean child baseline Brussel sprouts and whole-meal pasta intakes were 19.0 ± 24.2 g and 86.0 ± 69.7 g per meal, respectively. No meaningful differences in intake were found post-intervention or between groups. More children reported a neutral or positive liking towards the whole-meal pasta in the intervention group compared to those in the control group. No change was found for liking of Brussel sprouts.

Conclusions for practice

The intervention was found to be feasible however more studies on larger samples are needed to validate feasibility. Integrating digital interventions in the home and promoting meal preparation may improve child reported acceptance of some healthy foods. Using such technology may save time for parents and engage families in consuming healthier meals.

Perceived barriers to vegetable intake among urban adolescents from socioeconomically disadvantaged backgrounds: A qualitative study from the perspective of youth workers and teachers

Eating habits established during adolescence have been shown to track into adulthood. Adolescents from lower socioeconomic status groups tend to have lower intakes of vegetables as compared with their more affluent peers. However, there is limited evidence about the determinants of vegetable intake in this population group. Therefore, this study aimed to explore the barriers to vegetable intake in adolescents living in socioeconomically disadvantaged areas through the perspective of school teachers and youth workers. A total of 20 semi-structured interviews were conducted with post-primary school teachers and youth workers from disadvantaged areas in Dublin, Ireland. Thematic analysis was applied to analyze the data. Eleven themes were identified and fitted within the Socioecological Model of Health: adolescent's food preferences, lack of early exposure and familiarity with vegetables, lack of interest, knowledge and skills at the individual and family level, parenting practices around nutrition, living difficulties, peers' influence and social norms around nutrition, dual role of social media, lack of resources and support to promote healthy eating, competition between unhealthy food vs. vegetables, lack of adequate approaches & initiatives at the community and at the public policy levels, and lack of State support to promote healthy eating. Although several actions could be taken at the personal and interpersonal levels, more efforts are needed at the organizational, community and public policy levels to improve dietary choices and vegetable intake among adolescents in socioeconomically deprived areas. These findings will inform the development of tailored intervention strategies and policies for these vulnerable youths.

Urban-rural disparities in childhood obesogenic environments in the United States: Application of differing rural definitions

BACKGROUND

Research is needed that identifies environmental resource disparities and applies multiple rural definitions. Therefore, this study aims to examine urban-rural differences in food and physical activity (PA) environment resource availability by applying several commonly used rural definitions. We also examine differences in resource availability within urban-rural categories that are typically aggregated.

METHODS

Six food environment variables (access to grocery/superstores, farmers' markets, fast food, full-service restaurants, convenience stores, and breastfeeding-friendly facilities) and 4 PA environment variables (access to exercise opportunities and schools, walkability, and violent crimes) were included in the childhood obesogenic environment index (COEI). Total COEI, PA environment, and food environment index scores were generated by calculating the average percentile for related variables. US Department of Agriculture Urban Influence Codes, Office of Management and Budget codes, Rural-Urban Continuum Codes, Census Bureau Population Estimates for percent rural, and Rural Urban Commuting Area Codes were used. One-way ANOVA was used to detect urban-rural differences.

RESULTS

The greatest urban-rural disparities in COEI (F=310.2, P<.0001) and PA environment (F=562.5, P<.0001) were seen using RUCC codes. For food environments, the greatest urban-rural disparities were seen using Census Bureau percent rural categories (food: F=24.9, P<.0001). Comparing remote rural categories, differences were seen for food environments (F=3.1, P=.0270) and PA environments (F=10.2, P<.0001). Comparing metro-adjacent rural categories, differences were seen for PA environment (F=4.7, P=.0090).

CONCLUSION

Findings inform future research on urban and rural environments by outlining major differences between urban-rural classifications in identifying disparities in access to health-promoting resources.

What are the determinants of vegetable intake among adolescents from socioeconomically disadvantaged urban areas? A systematic review of qualitative studies

BACKGROUND

Evidence available on the determinants of vegetable intake in young populations is inconsistent. Vegetable intake is particularly low in adolescents from less-affluent backgrounds, yet no systematic review of qualitative studies investigating determinants for vegetable intake specifically has been conducted to date in this group. This systematic review aimed to identify determinants of vegetable intake in adolescents from socioeconomically disadvantaged urban areas located in very high-income countries reported in qualitative studies.

METHODS

Five electronic databases (PubMed, Web of Science, CINAHL, PsycINFO and ERIC) were searched until August 2022. The search strategy used combinations of synonyms for vegetable intake, adolescents, and qualitative methodologies. Main inclusion criteria were studies exploring views and experiences of motivators and barriers to vegetable intake in a sample of adolescents aged 12-18 years from socioeconomically disadvantaged urban areas in very high income countries. Study quality assessment was conducted using criteria established in a previous review.

RESULTS

Sixteen studies were included out of the 984 screened citations and 63 full texts. The synthesis of findings identified the following determinants of vegetable intake: sensory attributes of vegetables; psychosocial factors (nutrition knowledge, preferences/liking, self-efficacy, motivation); lifestyle factors (cost/price, time, convenience); fast food properties (taste, cost, satiety); home environment and parental influence; friends' influence; school food environment, nutrition education and teachers' support; and availability and accessibility of vegetables in the community and community nutrition practices. Studies attained between 18 and 49 out of 61 quality points, with eleven of 16 studies reaching ≥ 40 points. One main reason for lower scores was lack of data validation.

CONCLUSION

Multiple determinants of vegetable intake were identified complementing those investigated in quantitative studies. Future large scale quantitative studies should attempt to examine the relative importance of these determinants in order to guide the development of successful interventions in adolescents from socioeconomically disadvantaged backgrounds.

Is Adolescents' Free Sugar Intake Associated with the Free Sugar Intake of Their Parents?

High free sugar intake can lead to increased dental caries, obesity, and other health risks among adolescents. Studies have shown that family factors, especially parents, are one of the primary factors influencing adolescents' sugar intake. This study aims to investigate the influence of adolescent parents' free sugar intake, knowledge, attitude, and practice (KAP) on adolescents' free sugar intake. A total of 1090 pairs of adolescents and their parents from 10 secondary schools in Changsha were enrolled in a cross-sectional study. Free sugar intakes of parents and adolescents were measured using the food frequency questionnaire (FFQ). The current status of parents' knowledge, attitude, and practice in consuming free sugar was investigated using online and offline questionnaires. Parental free sugar intake was 11.55 (5.08, 21.95) g/d, and that of adolescents was 41.13 (19.06, 80.58) g/d. Parental free sugar intake, free sugar knowledge level, intake behavior, and guidance behavior were associated with adolescent free sugar intake. A superior level of parental free sugar knowledge (adjusted OR = 0.726, 95% CI: 0.557~0.946) was a protective factor for adolescent free sugar intake. Moderate and high levels of parental free sugar intake (adjusted OR = 1.706, 95% CI: 1.212~2.401; adjusted OR = 2.372, 95% CI: 1.492~3.773, respectively) were risk factors for free sugar intake in adolescents. Given the importance of parental influence on the adolescent free sugar intake, further limiting parental intake and increasing awareness of free sugars could play an active role in future interventions for adolescents' free sugar intake.

Diet Quality and Contextual Factors Influencing Food Choice among Adolescents with Food Security and Food Insecurity in Baltimore City

This study evaluated differences in overall diet quality, diet quality components, and food-related contextual factors between adolescents with food security and those with food insecurity. Mixed methods analysis was conducted on data from three 24-h dietary recalls from 61 adolescents ages 14–19 years old living in Baltimore, Maryland, USA in 2020–2021. All adolescents were sampled from households eligible for the Supplemental Nutrition Assistance Program in 2020. There were no significant differences in overall diet quality or components between adolescents with food security and those with food insecurity in this sample, except for seafood and plant proteins, which was higher for adolescents with food insecurity. Qualitative analysis found that adolescents were largely influenced by their parents and the home food environment, and that workplace environments enabled adolescents to eat foods high in refined grains, sugar, and saturated fat. These findings provide insight about the experiences of low-income adolescents during times when they are home for prolonged periods (i.e., emergency school closures, summer, and winter breaks). Programs and policies that aim to improve healthy food access may positively impact adolescent food security and diet quality, and it is important to ensure that healthy foods are available and accessible to adolescents in the places where they spend the most time. Multilevel interventions in the home, school, and workplace may be most effective in encouraging healthy eating behaviors among adolescents.

Parental food consumption and diet quality and its association with children's food consumption in families at high risk of type 2 diabetes: the Feel4Diabetes-study

OBJECTIVE

To examine the parental food consumption and diet quality and its associations with children's consumption in families at high risk for developing type 2 diabetes mellitus across Europe. Also, to compare food frequency consumption among parents and children from high-risk families to the European Dietary guidelines/recommendations.

DESIGN

Cross-sectional study using Feel4diabetes FFQ.

SETTING

Families completed FFQ and anthropometric measures were obtained. Linear regression analyses were applied to investigate the relations between parental food consumption and diet quality and their children's food consumption after consideration of potential confounders.

PARTICIPANTS

2095 European families (74·6 % mothers, 50·9 % girls). The participants included parent and one child, aged 6-8 years.

RESULTS

Parental food consumption was significantly associated with children's intake from the same food groups among boys and girls. Most parents and children showed under-consumption of healthy foods according to the European Dietary Guidelines. Parental diet quality was positively associated with children's intake of 'fruit' (boys: β = 0·233, P < 0·001; girls: β = 0·134, P < 0·05) and 'vegetables' (boys: β = 0·177, P < 0·01; girls: β = 0·234, P < 0·001) and inversely associated with their 'snacks' consumption (boys: β = -0·143, P < 0·05; girls: β = -0·186, P < 0·01).

CONCLUSION

The present study suggests an association between parental food consumption and diet quality and children's food intake. More in-depth studies and lifestyle interventions that include both parents and children are therefore recommended for future research.

School and community drivers of child diets in two Arab cities: The SCALE protocol and innovative tools to assess children’s food environments

Background

In the context of the rapid nutrition transition experienced by middle-income countries of the Arab region, children and adolescent’s food choices and dietary behaviors are early risk factors for the development of non-communicable diseases. Assessment of factors influencing food choices among this age group is challenging and is usually based on self-reported data, which are prone to information and recall bias. As the popularity of technologies and video gaming platforms increases, opportunities arise to use these tools to collect data on variables that affect food choice, dietary intake, and associated outcomes. This protocol paper describes the SCALE study (School and community drivers of child diets in Arab cities; identifying levers for intervention) which aims to explore the environments at the level of households, schools and communities in which children’s food choices are made and consequently identify barriers and enablers to healthy food choices within these environments.

Methods

Field studies are being conducted in primary schools, among children aged 9–12 years, in Greater Beirut, Lebanon and Greater Tunis, Tunisia. A stratified random sample of 50 primary schools (public and private) are selected and 50 children are randomly selected from grades 4-5-6 in each school. The study includes surveys with children, parents/caregivers, school directors, teachers, and nutrition/health educators to assess individual diets and the contextual factors that influence children’s food choices. Innovative locally adapted tools and methods such as game-based choice experiments, wearable cameras and neighborhood mapping are used to describe the environments in which children’s food choices are made.

Discussion

The SCALE study will generate contextual knowledge on factors in school and neighborhood environments that influence child dietary behaviors and will inform multi-level interventions and policies to address childhood malnutrition (under-and over-nutrition). By integrating methods from various disciplines, including economics, data science, nutrition, and public health and by considering factors at various levels (home, school, and neighborhood), the study will identify levers for intervention with the potential to improve children’s dietary behaviors. This will help fill existing gaps in research on food systems and consequently guide positive change in Lebanon and Tunisia, with the potential for replicability in other contexts.

Determinants of vegetable intake among urban socio-economically disadvantaged adolescents: a systematic review of quantitative studies

OBJECTIVE

To investigate the determinants of vegetable intake in urban socio-economically disadvantaged adolescents to inform the development of an intervention programme.

DESIGN

A narrative systematic review was carried out by searching five electronic databases from 2013 to 2020. The descriptors used for the search strategy were vegetable intake, adolescents, determinants and correlates. Inclusion criteria were including a sample of socio-economically disadvantaged adolescents aged 12-18 years, evaluation of the association between vegetable intake and determinants of intake, and conducted in urban settings of high-income countries. Thirteen studies met the inclusion criteria. Identified determinants of vegetable intake were reported according to the five levels of the socio-ecological model of health.

SETTING

Studies included in the review were conducted in four countries: USA (n 8), Australia (n 3), Ireland (n 1) and New Zealand (n 1).

PARTICIPANTS

Adolescents aged 12-18 years from socio-economically disadvantaged backgrounds living in urban settings.

RESULTS

Thirty-nine determinants were identified. Nutrition knowledge was the only determinant consistently investigated in several independent samples which was not associated with vegetable intake in socio-economically disadvantaged adolescents. For the remaining potential determinants, it was not possible to examine the consistency of evidence as there were not enough studies investigating the same determinants. Most of the studies followed a cross-sectional design and were carried out in school settings.

CONCLUSIONS

There is a need for further studies on the determinants of vegetable intake in this population preferably with longitudinal designs and beyond the school setting in different countries to guide the development of successful interventions.

Parent Fruit and Vegetable Consumption Outcomes from the Translational 'Time for Healthy Habits' Trial: Secondary Outcomes from a Partially Randomized Preference Trial

Healthy eating and active living interventions targeting parents of young children could have benefits for both children and parents. The aim of this study was to assess the effectiveness of two remotely delivered healthy eating and active living interventions delivered at scale to parents, in increasing parent vegetable and fruit consumption (pre-specified secondary outcomes). Parents of children aged 2–6 years residing in New South Wales, Australia (n = 458), were recruited to a partially randomized preference trial consisting of three groups (telephone intervention (n = 95); online intervention (n = 218); written material (Control) (n = 145)). This design allowed parents with a strong preference to select their preferred intervention, and once preference trends had been established, all parents that were subsequently recruited were randomized to obtain robust relative effects. Parent vegetable and fruit consumption was assessed via telephone interview at baseline and 9 months later. At follow-up, randomized parents who received the telephone intervention (n = 73) had significantly higher vegetable consumption compared to those who received the written control (n = 81) (+0.41 serves/day, p = 0.04), but there were no differences in parents allocated to intervention groups based on preference. No differences in fruit consumption were found for randomized or preference participants for either the telephone or online intervention. There may be some benefit to parents participating in the Healthy Habits Plus (telephone-based) intervention aimed at improving the eating behaviors of their children.

Where do Dutch adults obtain their snack foods? Cross-sectional exploration of individuals' interactions with the food environment

We investigated frequency of consumption and location of obtaining snack foods and sociodemographic differences therein. Data: cross-sectional survey data (N = 1784 Dutch adults 18-65 years) on the frequency of consumption of 10 snack foods and where they obtained them. Adjusted logistic regression analyses revealed notable differences in the frequency of snack food consumption between younger and older adults and between those with low vs. high socioeconomic position (SEP). The location of obtaining snack foods also differed between sociodemographic groups with supermarkets forming an important point-of-purchase for snack foods, especially for those with low SEP and with children in their household.

Central Persons in Sustainable (Food) Consumption

What people eat has become a highly political issue, closely intertwined with public health, environmental concerns, and climate change. Individuals' consumption decisions tend to be greatly influenced by the people that surround them, and this seems to be especially true when it comes to food. In recent years, alongside close contacts, such as family and friends, a myriad of social influencers have appeared on the screens, sharing opinions on what (not) to eat. Presenting results from a youth survey conducted in Sweden in 2019 (N = 443), this paper shows that social media have become the primary source of information about food and eating for youths, followed by schools and families. However, primary sources of influence continue to be parents and the family at large. Furthermore, the study shows that it is possible to identify 'central persons', i.e., relatively clear-cut groups of people whose food choices-measured as tendency to eat climate friendly-is mirrored by the youths, both in their everyday food preferences and in their broader political awareness as expressed through political consumerism. A conclusion from this is that certain people can be particularly successful at inspiring larger numbers of other people to engage with healthier and environmentally friendlier (food) consumption in a society.

Adolescents' proxy reports on obesity-related parenting practices: factorial validity and reliability across four behavioral domains

Background

Adolescents’ energy balance behaviors are precursors to obesity shaped by the practices or strategies that many parents implement. Although key stakeholders to their families, adolescents are rarely considered to report on these obesity-related parenting practices. The aim of this study is to assess the factorial and predictive validity of adolescents’ proxy-report of parents’ obesity-related parenting across four behavioral domains.

Methods

This study used data from the Family Life, Activity, Sun, Health, and Eating (FLASHE) study. This study tests whether adolescents’ proxy reports about their parents’ obesity-related parenting are significantly associated with parents’ responses on their own obesity-related parenting, as well as whether these reports are significantly associated to parent-adolescent energy balance behaviors. Factorial validity was assessed using linear regression and Confirmatory Factor Analysis (CFA), whereas predictive validity was assessed using Actor-Partner Interdependence Modeling (APIM).

Results

Regression results indicated that adolescents’ proxy report is significantly associated with parents’ report of their own parenting in all four domains (β = .59—.71; p < 0.05). CFA results indicated a final factor structure that loaded significantly onto hypothesized obesity-related parenting domains (β > .30) in both adolescents and parents. APIM results indicated that both parent- (β = .32; p < 0.05) and adolescent-(β = .21; p < 0.05) reported obesity parenting for fruit and vegetable consumption were associated with their own fruit and vegetable intake. In addition, adolescent-reported physical activity parenting was significantly associated with adolescent physical activity (β = 0.23; p < 0.05). Regarding partner effects, only parent-reported parenting for fruit and vegetable consumption were significantly associated with adolescent intake of fruit and vegetables (β = 0.15, p < 0.05) and adolescent-reported physical activity parenting was significantly associated with parental physical activity (β = 0.16, p < 0.05). Neither adolescent nor parent reported parenting were significantly associated with screen time or junk food intake outcomes. Each final obesity-related parenting scale had good internal consistency (a = .74-.85).

Conclusions

We found that adolescent- and parent-reported obesity-related parenting were significantly associated, while adolescent-reported parenting were more explanatory of fruit and vegetable intake and physical activity than parent-reported parenting. These findings suggest that adolescent proxy reports may be a valid source of information on obesity-related parenting.

Effectiveness of Nutritional Strategies on Improving the Quality of Diet of Children from 6 to 12 Years Old: A Systematic Review

Dietary habits, that are formed during childhood and consolidated in adulthood, are known to influence the development of future chronic diseases such as metabolic syndrome or type 2 diabetes. The aim of this review was to evaluate the effectiveness of nutritional interventions carried out in recent years focused on improving the quality of the diet of the child population. A systematic search of the PubMed and Scopus databases was performed from January 2011 until September 2021. A total of 910 articles were identified and screened based on their title, abstract and full text. Finally, 12 articles were included in the current systematic review. Of those, in six studies the intervention was based on the provision of healthy meals and in the other six studies the intervention focused on modifying the school environment. Six of the studies selected included other components in their intervention such as nutritional education sessions, physical activity and/or families. A wide variety of methods were used for diet assessments, from direct method to questionnaires. The results suggest that interventions that modify the school environment or provide different meals or snacks may be effective in improving children’s dietary patterns, both in the short and long term. Further research is necessary to evaluate the real effectiveness of strategies with multidisciplinary approach (nutritional sessions, physical activity and family’s involvement).

Associations between mother-child dyad dietary patterns and child anthropometric measures among 6-year-old children

The goals of this study were to study relationships between maternal and children's dietary patterns (DPs) and to assess how children's DP was associated with child anthropometry. This cross-sectional study included 788 pairs of 6-year-old girls and mothers in health centers in Tehran, Iran. Information on dietary intake was collected with a 168-item food frequency questionnaire. Principal component factor analysis was performed to label different data-driven dietary patterns. Three different binary logistic regression models were used to evaluate the associations between child's DPs and child anthropometry. A positive correlation was found between all maternal patterns and child's Western DP (p < 0.001). Maternal prudent and Western DPs were correlated with child's high-protein DP (p < 0.001). Children's high-protein DP was negatively correlated with maternal high fat DP (p < 0.001). Maternal prudent and high fat DPs were correlated with prudent DP in children (p < 0.001). In adjusted models, a child being in the highest compared to the first quartile of the high-protein DP was associated with decreased odds of underweight and wasting (OR 0.43; 95% CI 0.23-0.80).Conclusion: The present study showed inverse associations between a high-protein DP in children and being underweight and wasted. Also, a positive correlation was found between all maternal DPs and children's Western DPs. This correlation should be taken into account while managing child nutrition by means of educating parents on the influence of their own dietary pattern on their children. Moreover, getting enough protein through a balanced diet should be considered in children. What is Known: • Some research exists on the intake of specific foods in relation to risk of abnormal growth in children. • Less is known about the relationship between mothers' and children's food intake. What is New: • Better adherence to a high-protein dietary pattern was significantly associated with lower risk of being both underweight and wasted. • This study suggests that correlation between mothers' and their children's dietary patterns exists, which should be taken into consideration when managing child nutrition.

Spatial clustering patterns and regional variations for food and physical activity environments across the United States

This study examined spatial patterns of obesogenic environments for US counties. We mapped the geographic dispersion of food and physical activity (PA) environments, assessed spatial clustering, and identified food and PA environment differences across U.S. regions and rurality categories. Substantial low food score clusters were located in the South and high score clusters in the Midwest and West. Low PA score clusters were located in the South and high score clusters in the Northeast and Midwest (p < .0001). For region, the South had significantly lower food and PA environment scores. For rurality, rural counties had significantly higher food environment scores and metropolitan counties had significantly higher PA environment scores (p < .0001). This study highlights geographic clustering and disparities in food and PA access nationwide. State and region-wide environmental inequalities may be targeted using structural interventions and policy initiatives to improve food and PA access.

Snack Food Consumption across the Pune Transect in India: A Comparison of Dietary Behaviors Based on Consumer Characteristics and Locations

This study examines patterns of snack food consumption (SFC) in the rural-urban-slum transect (RUST) of a large city Pune and its precincts (population 10 million) in India. The transect structure aims to mimic a representative survey for the location capturing differences by age, gender, urbanicity, and socio-economic levels. Dietary data from 1405 individuals were used to describe snacking patterns and other food consumed at different frequencies; extent of physical activity; and Body Mass Index (BMI) and waist circumference of children, adolescents, and adults. Our results indicate high incidence of SFC across all population age groups, gender, socio-economic levels, and locations. A distinctive finding in relation to studies in high income countries is the prevalence of hunger snacking with 70% identifying hunger as the primary reason for SFC. Apart from hunger, particularly for adolescents, peer influence and social interactions played a significant role in SFC. Dietary behaviors of slum dwellers were characterized by three-quarters of them having SFC together with family members at home. SFC supplemented calories for low-income consumers and complemented calorie intake for high income ones. No significant association with BMI is possibly due to obesogenic SFC being likely offset by lower consumption of non-snack food and higher physical activity among poor and slum dwellers. Promoting awareness about diets and lifestyles, improving physical and economic access to healthier snacks and nutrient dense foods can improve diet quality in a large and heterogeneous population such as Pune.

Incongruency of youth food and physical activity environments in the United States: Variations by region, rurality, and income

Local environments are increasingly the focus of health behavior research and practice to reduce gaps between fruit/vegetable intake, physical activity (PA), and related guidelines. This study examined the congruency between youth food and PA environments and differences by region, rurality, and income across the United States. Food and PA environment data were obtained for all U.S. counties (N = 3142) using publicly available, secondary sources. Relationships between the food and PA environment tertiles was represented using five categories: 1) congruent-low (county falls in both the low food and PA tertiles), 2) congruent-high (county falls in both the high food and PA tertiles), 3) incongruent-food high/PA low (county falls in high food and low PA tertiles), 4) incongruent-food low/PA high (county falls in low food and high PA tertiles), and 5) intermediate food or PA (county falls in the intermediate tertile for food and/or PA). Results showed disparities in food and PA environment congruency according to region, rurality, and income (p < .0001 for each). Nearly 25% of counties had incongruent food and PA environments, with food high/PA low counties mostly in rural and low-income areas, and food low/PA high counties mostly in metropolitan and high-income areas. Approximately 8.7% of counties were considered congruent-high and were mostly located in the Northeast, metropolitan, and high-income areas. Congruent-low counties made up 10.0% of counties and were mostly in the South, rural, and low-income areas. National and regional disparities in environmental obesity determinants were identified that can inform targeted public health interventions.

Family health climate: a qualitative exploration of everyday family life and health

Background

The family is an important social environment for children’s, adolescents’ and adults’ health. However, studies mostly focused on dyadic and unidirectional influences of parents on their children. Studies addressing influences arising from daily family life and including family-level influences are rare and the existing studies solely focus on the relevance for children’s health or health-related behaviors. We use a qualitative approach to explore how daily family life and its inherent health-related cues affect family members’ physical activity and eating behavior.

Methods

Semi-structured interviews utilizing an interview guide were conducted. Since we aimed to examine family life, we analyzed both parents’ and their children’s views on health-related interaction patterns and family environmental influences on individuals’ health-related behavior. Twenty-two members of seven families were interviewed. Transcripts of the interviews were systematically analyzed following Grounded Theory principles.

Results

The interviews revealed that various individual as well as environmental factors shape health-related aspects of daily family life. A model was developed that organizes these influencing factors on family life with regard to health-related interactions and the emergence of the Family Health Climate (FHC) – reflecting shared perceptions and cognitions regarding a healthy lifestyle within families – and its consequences. Family interactions and family time, often realized through shared family meals, are key factors for families’ health with regard to nutrition and physical activity. The FHC showed to affect various aspects related to health behavior of individual family members.

Conclusions

The model sheds light on underlying processes and mechanisms of family life that influences individuals’ health-related behavior. Based on a better understanding of the association between family life and individual health behavior the development of family-based interventions can be informed. Furthermore, the insights can help to guide further research focusing on families as a system.

What Do Secondary Schools Need to Create Healthier Canteens? The Development of an Implementation Plan

Introduction: The Netherlands Nutrition Centre developed guidelines to improve the availability and accessibility of healthier food products in Dutch canteens. This paper describes the development of an implementation plan to facilitate implementation of Guidelines for Healthier Canteens in Dutch secondary schools. Materials and Methods: In cooperation with stakeholders (i.e., school/caterer managers/employees, school canteen advisors, researchers) and based on theory, we developed an implementation plan in three steps. First, we identified factors that impede/facilitate stakeholders to create a healthier school canteen during 14 interviews. Second, 25 experts discussed and prioritized these identified factors in an expert meeting. Third, we translated these factors into tools to be included in the implementation plan, by making use of behavior change taxonomies and evidence-based implementation strategies. Results: The plan aims to support stakeholders in implementing healthier school canteens and consists of five tools: (1) tailored advice based on an online questionnaire to assess schools' and stakeholders' context and the Canteen Scan (i.e., an online tool to assess the availability and accessibility of food/drink products); (2) communication materials with information and examples; (3) online community for support by sharing experiences/questions; (4) digital newsletter as reminder/support; (5) fact sheet with students' needs/wishes to tailor the canteen. Discussion: This study illustrates how collaboration between science, policy and practice resulted in a tailored implementation plan aimed to support schools to adhere to school canteen policy. This development serves as a good example for researchers, health promotion policymakers, and practitioners how to create an implementation plan that fits the needs of stakeholders.

The Food Environment of Primary School Learners in a Low-to-Middle-Income Area in Cape Town, South Africa

Rapid changes in food environments, where less nutritious foods have become cheaper and more accessible, have led to the double burden of malnutrition (DBM). The role food environments have played in shaping the DBM has attained global interest. There is a paucity of food environment research in low-to-middle-income countries. We conducted a case study of the food environments of school aged learners. A primary school in Cape Town was recruited. A multi-method design was used: a home food and eating behaviours questionnaire completed by 102 household respondents and four questions completed by 152 learners; learner participatory photography; a semi-structured school principal interview; a tuckshop inventory; observation of three-day tuckshop purchases. Foods that were commonly present in households: refined carbohydrates, fats/oils, chicken, processed meats, vegetables, fruit, legumes, snacks/drinks. Two thirds of households had rules about unhealthy drinks/snacks, ate supper together and in front of the TV, ate a home cooked meal five–seven times/week and ate breakfast together under two times/week. Vegetables were eaten under two times/week in 45% of households. A majority of learners (84%) took a lunchbox to school. Twenty-five learners photographed their food environment and 15 participated in semi-structured interviews. Six themes emerged: where to buy; what is available in the home; meal composition; family dynamics; peer engagement; food preparation. Items bought at informal food outlets included snacks, drinks and grocery staples. The principal interview revealed the establishment of a healthy school food environment, including a vegetable garden, although unhealthy snacks were sold at the tuckshop. Key dimensions of the food environment that require further investigation in disadvantaged urban and informal settlement areas include the home availability of unhealthy foods, eating behaviours in households and healthfulness of foods sold by informal food outlets.

Physical activity modification in youth with congenital heart disease: a comprehensive narrative review

Congenital heart disease (CHD) affects nearly 1% of births. As survival rates have dramatically improved, the majority of individuals with CHD now live into adulthood. As these patients age, they become prone to a large range of complications, such as chronic heart failure and acquired cardiovascular disease. Promotion of a healthy and active lifestyle from childhood onwards has been suggested as a sustainable and effective strategy to enhance cardiovascular health, improve quality of life and reduce immediate and long-term risk in people with CHD. Well-established physical activity consensus statements for youth with CHD have now been published. In this article, we review how increasing physical activity in youth with CHD may offer immediate and long-term cardiovascular benefits, what is known about physical activity in children with CHD, describe the unique factors that contribute to achieving sufficient and insufficient physical activity levels and summarize the evidence of trials on physical activity promotion in youth with CHD. Furthermore, we discuss some of the challenges that need to be addressed by further research regarding the optimal strategy, timing and format of physical activity intervention programmes in children and adolescents with CHD. IMPACT: Congenital heart disease (CHD) affects nearly 1% of births, with the majority of individuals with CHD now living into adulthood due to improved survival. As CHD patients age, they become prone to a large range of cardiovascular complications. This article discusses how and why increasing physical activity in youth with CHD may offer immediate and long-term cardiovascular benefits, the barriers to achieving sufficient physical activity levels and the evidence from trials on physical activity promotion in youth with CHD. The optimal strategy, timing and format of physical activity intervention programmes in children and adolescents with CHD are discussed.

Feeding style profiles are associated with maternal and infant characteristics and infant feeding practices and weight outcomes in African American mothers and infants

Much literature links individual feeding styles to infant feeding practices and growth; however, parents' feeding styles are not discrete and may vary by context. We use latent profile analysis (LPA) as a person-centered approach to categorize infant feeding style patterns, test factors predicting profile membership, and examine if profiles are associated with infant feeding and weight. Additionally, we test the impact of a responsive feeding intervention on profile membership and stability. Data come from 270 African-American women and infants participating in the Mothers and Others Study, an early life obesity prevention intervention. LPA was used to categorize mothers across five constructs (laissez-faire, pressuring, restrictive, responsive and indulgent) measured at 28-weeks gestation and 3- and 15-months postpartum. Adjusted multinomial regression and regression models test the characteristics associated with profile membership and the associations between profile membership and breastfeeding and infant weight-for-age z-score (WAZ). We identified two groups (Positive and Less Responsive) prenatally, an additional group (High Controlling) at 3 months and a fourth group (High Indulgent) at 15 months. Several characteristics differed between the groups, including maternal age, income and depressive symptoms, infant sex and temperament, and treatment group. Mothers in the Positive group were more likely to breastfeed at 3 months. Infants with mothers in the High Controlling group had higher WAZ at 15 months. The intervention was associated with more Positive feeding practices at 15 months and a greater likelihood of remaining in the Positive group across the study. LPA identified profiles that are associated with maternal and infant characteristics and treatment group and with better feeding practices and growth outcomes, providing preliminary evidence that early intervention promoting more responsive feeding profiles may improve infant outcomes.

Development and testing of the Sustainable Nutrition Environment Measures Survey for retail stores in Ontario

OBJECTIVE

To develop and test a tool to assess the price and availability of low-carbon footprint and nutritionally balanced dietary patterns in retail food environments in Ontario, Canada.

DESIGN

Availability and price of selected food from discount and regular grocery stores (n 23) in urban/rural areas of northern/southern Ontario were assessed with the Sustainable Nutrition Environment Measures Survey in 2017.

SETTING

Ontario, Canada.

RESULTS

Inter-rater reliability was high for price (intra-class correlation coefficients = 0·819) and for availability (Cohen's κ = 0·993). The tool showed 78 % of the selected food items were available in all stores. Overall, price differences were small between urban and rural locations, and northern and southern Ontario. The greatest price difference was between discount and regular stores.

CONCLUSIONS

The tool showed excellent inter-rater agreement. Researchers and public health dietitians can use this tool for research, practice and policy to link consumer-level health outcomes to the retail environment.

Caregivers' Role in the Effectiveness of Two Dutch School-Based Nutrition Education Programmes for Children Aged 7-12 Years Old

Childhood eating behaviours can track into adulthood. Therefore, programmes that support early healthy eating, including school-based nutrition education programmes, are important. Although school-based programmes may be beneficial in improving nutrition knowledge, impact on actual fruit and vegetable (FV) intake is generally limited as FV intake is also influenced by the home environment. The current study includes secondary analyses of data from an evaluation study on Dutch nutrition education and examined the role of caregivers’ health promotion behaviours (HPB) in influencing healthy eating behaviours in primary school children (n = 1460, aged 7–12 years) and whether caregivers’ HPB contribute to programme effectiveness. Children’s nutrition knowledge, FV intake and caregivers’ HPB (FV/sugar-sweetened beverages/sweets provision to take to school, cooking together and talking about healthy food at home) were measured by child-reported questionnaires at baseline, during, and 6 months post-programme. Results indicated that caregivers’ HPB was positively associated with children’s healthy eating behaviours and that programme effectiveness was highest in those in the lower HPB subcategory. In conclusion, children with less encouragement to eat healthily at home potentially benefit more from school-based nutrition education programmes than children receiving more encouragement. This highlights the important role of the home environment in supporting healthy eating behaviour in children.

Psychometric examination of the Japanese translation of the Satter eating competence Inventory-2.0™ for parents of fifth and sixth grade students

AIM

To verify the reliability and validity of a Japanese translation of the Satter eating competence Inventory-2.0™ (ecSI-2.0™) for parents of fifth and sixth grade elementary school students.

METHODS

Participants were parents who prepared meals for their children aged 10-12 years. A preliminary study was conducted with 11 parents using semi-structured interviews and questionnaires, followed by a main study of 2,825 parents. Internal consistency and test-retest methods were used to verify reliability. Face and content validity were confirmed in the preliminary study, and feasibility was examined by the valid response rate and response time. Construct validity was verified using factor validity and known population validity.

RESULTS

Of the 2,825 persons surveyed, 626 returned valid responses, and among the 60 persons who received the re-survey, 48 returned valid responses. The average score of the Japanese translation of the ecSI-2.0™ was 33.1 (SD ± 7.8) points. Cronbach's alpha coefficient for the whole scale was .87 and ranged from .67-.79 for the four subscales. The test-retest method confirmed the scale's stability. Factor analysis confirmed that reproducibility of the four factors was similar to the original version. In the examination of known population validity, the same correlation as the original edition was confirmed.

CONCLUSIONS

The Japanese translation of the ecSI-2.0™ may be reliable and valid for understanding eating competence related to behavior of parents of school-age children.

Explaining the dimensions of social support for breakfast and healthy snacks in students: a qualitative study

BACKGROUND

breakfast elimination as well as consumption of low-value snacks is ever increasing among adolescents. This study sought to explain the dimensions of social support for breakfast and healthy snacks among students.

METHODS

A qualitative research was conducted in Isfahan, Tehran, and Khorramabad, Iran high schools in 2017-18. Data were obtained from five focus group discussions and 35 in-depth interviews as well as semi-structured interviews with students of both sex, parents and school authorities. The data simultaneously analyzed using conventional content analysis in three stages including preparation, organization, and reporting. Prolonged engagement, maximum variation of sampling and member check were the enrichment factors of the research.

RESULTS

Three main categories emerged. First, family supports with sub- categories of family in the school programs as well as mother-sponsored support and family life patterns. Second, school supports with sub- categories of instrumental and informational support. And third, support of other community organizations with sub- categories of intra-department coordination and mass media.

CONCLUSION

The concepts emerging in the present study develop multilevel ecological strategies to promote nutritional health including family, school, and community organizations such as school renovations, municipalities, police, education, and mass media to promote healthy breakfast and snack behavior are applicable for students.

The association between father involvement in caregiving and early childhood overweight or obesity

BACKGROUND

Despite the increasing trend of paternal engagement in caregiving, fathers remain underrepresented in studies on parenting and childhood obesity.

OBJECTIVES

This study examined the association between father involvement in caregiving and child's weight status within a longitudinal dataset from Japan.

METHODS

The data were obtained from a population-based cohort study in Japan (N = 29 584). The association between father's involvement in child caregiving (age 18 months) on the weight status of the same children at age 3.5 years was examined by logistic regression and linear regression analysis. Furthermore, we checked the interaction between maternal employment & father involvement by creating four mutually exclusive groups of families.

RESULTS

Children whose fathers were highly involved in caregiving were less likely to be overweight (OR = 0.90, 95% CI, 0.85-0.96). Employed mothers with high paternal involvement in caregiving were 30% less likely to have children with overweight or obesity compared to those with low paternal involvement (95% CI, 0.55-0.90).

CONCLUSIONS

Father involvement in caregiving is associated with the development of overweight or obesity in early childhood, and may also modify the association between maternal employment and child's weight status. Social policies to support shared child-rearing such as expanding paid parental leave could help families to raise children with healthy weight.

The Impact of a Multi-Pronged Intervention on Students' Perceptions of School Lunch Quality and Convenience and Self-Reported Fruit and Vegetable Consumption

School lunch programs provide an opportunity to improve students' diets. We sought to determine the impact of a multifaceted intervention (cafeteria redesigns, increased points-of-sale and teacher education) on secondary students' perceptions of school-lunch quality and convenience and fruit and vegetable intake. Surveys (n = 12,827) from middle and high school students in 12 intervention and 11 control schools were analyzed. We investigated change in school-lunch perceptions and lunchtime and daily fruit and vegetable consumption from 2016 to 2018. Among 8th graders, perceptions that school lunch tastes good and that school lunch was enough to make students feel full increased 0.2 points (on a 5-point scale; p < 0.01) in intervention schools relative to control schools. Among 10th graders, lunchtime fruit and vegetable consumption increased 6% in intervention relative to control schools (p < 0.05 and p < 0.01 respectively). Daily fruit intake increased 0.1 cups/day in intervention relative to control schools among 9th graders (p < 0.01). This study provides important evidence on the limited effect of design approaches in the absence of meal changes. We observed only modest changes in school lunch perceptions and fruit and vegetable consumption that were not consistent across grades, suggesting that additional efforts are needed to improve school-lunch uptake.

Do Parent-Child Dyads with Excessive Body Mass Differ from Dyads with Normal Body Mass in Perceptions of Obesogenic Environment?

Background: This study addressed differences between parent–child dyads with excessive body mass (overweight or obesity) and dyads with normal body mass in obesity determinants, derived from social-ecological models. It was hypothesized that parents and their 5–11 years-old children with excessive body mass would (1) report lower availability of healthy food at home, (2) perceive fewer school/local community healthy eating promotion programs, (3) report lower persuasive value of food advertising. Methods: Data were collected twice (T1, baseline; T2, 10-month follow-up), including n = 129 parent–child dyads with excessive body mass and n = 377 parent–child dyads with normal body mass. Self-reported data were collected from parents and children; with body weight and height assessed objectively. General linear models (including analysis of variance with repeated measures) were performed to test the hypotheses. Results: Compared to dyads with normal body mass, dyads of parents and children with excessive body mass perceived lower availability of healthy food at home and fewer healthy eating promotion programs at school/local community (T1 and T2). These effects remained significant after controlling for sociodemographic variables. No significant differences in persuasive value of food advertising were found. Conclusions: Perceptions of availability of healthy food at home and healthy nutrition promotion may be relatively low in parent–child dyads with excessive weight which, in turn, may constitute a risk factor for maintenance of obesity.

Associations between family and home-related factors and child's snack consumption in a multi-ethnic population

BACKGROUND

Energy-dense snacks are considered unhealthy due to their high concentrations of fat and sugar and low concentrations of micronutrients. The present study aimed to evaluate associations between family and home-related factors and children's snack consumption. We explored associations within subgroups based on ethnic background of the child.

METHODS

Cross-sectional data of 644 primary school children (mean age: 9.4 years, 53% girls) from the population-based 'Water Campaign' study conducted in the Netherlands were used. Logistic regression analyses were used to evaluate the associations between family and home-related factors and child's snack intake.

RESULTS

Of the children, 28.7% consumed more than one snack per day. Children of parents who expressed more restrictive parenting practices towards the child's snack consumption (odds ratio (OR) = 2.5, P < 0.001), and who modelled snack eating less often (OR = 2.2, P < 0.001) had lower snack intake. Restrictive parenting practices and parental modelling of healthy snacking were significant for children with a Dutch or Moroccan/Turkish ethnic background, but not for children with a Surinamese/Antillean ethnic background.

CONCLUSIONS

We observed that parenting practices and parental modelling were independently associated with the child's snack intake. Also, the relationships between these factors and the child's snack consumption differed for children with distinct ethnic backgrounds.

Development of a national childhood obesogenic environment index in the United States: differences by region and rurality

Background

Diverse environmental factors are associated with physical activity (PA) and healthy eating (HE) among youth. However, no study has created a comprehensive obesogenic environment index for children that can be applied at a large geographic scale. The purpose of this study was to describe the development of a childhood obesogenic environment index (COEI) at the county level across the United States.

Methods

A comprehensive search of review articles (n = 20) and input from experts (n = 12) were used to identify community-level variables associated with youth PA, HE, or overweight/obesity for potential inclusion in the index. Based on strength of associations in the literature, expert ratings, expertise of team members, and data source availability, 10 key variables were identified – six related to HE (# per 1000 residents for grocery/superstores, farmers markets, fast food restaurants, full-service restaurants, and convenience stores; as well as percentage of births at baby (breastfeeding)-friendly facilities) and four related to PA (percentage of population living close to exercise opportunities, percentage of population < 1 mile from a school, a composite walkability index, and number of violent crimes per 1000 residents). Data for each variable for all counties in the U.S. (n = 3142) were collected from publicly available sources. For each variable, all counties were ranked and assigned percentiles ranging from 0 to 100. Positive environmental variables (e.g., grocery stores, exercise opportunities) were reverse scored such that higher values for all variables indicated a more obesogenic environment. Finally, for each county, a total obesogenic environment index score was generated by calculating the average percentile for all 10 variables.

Results

The average COEI percentile ranged from 24.5–81.0 (M = 50.02,s.d. = 9.01) across US counties and was depicted spatially on a choropleth map. Obesogenic counties were more prevalent (F = 130.43,p < .0001) in the South region of the U.S. (M = 53.0,s.d. = 8.3) compared to the Northeast (M = 43.2,s.d. = 6.9), Midwest (M = 48.1,s.d. = 8.5), and West (M = 48.4,s.d. = 9.8). When examined by rurality, there were also significant differences (F = 175.86,p < .0001) between metropolitan (M = 46.5,s.d. = 8.4), micropolitan (M = 50.3,s.d. = 8.1), and rural counties (M = 52.9,s.d. = 8.8) across the U.S.

Conclusion

The COEI can be applied to benchmark obesogenic environments and identify geographic disparities and intervention targets. Future research can examine associations with obesity and other health outcomes.

Investigating the momentary association between maternal support and children's fruit and vegetable consumption using ecological momentary assessment

Despite compelling evidence that fruit and vegetable (F/V) consumption can reduce the risk of obesity and chronic disease, most children fail to meet the daily recommendations for dietary consumption. Theoretical models and empirical findings suggest that parents play a key role in guiding children's overall dietary behaviors. To extend previous findings, the current study utilized ecological momentary assessment (EMA) on smartphones to assess the within-subject and between-subject effects of maternal support (i.e., encouragement, preparation) of F/V on their child's F/V consumption. Mother-child dyads (n = 191) completed six semi-annual 7-day waves of EMA surveys. EMA assessed mothers' past 2-h support for F/V and children's F/V consumption. At the within-subject level, greater maternal encouragement for F/Vs (OR = 2.41) and maternal preparation of F/Vs (OR = 1.43) than usual were associated with increased odds of their child eating F/V during the same 2-h window. At the between-subject level, greater maternal preparation of F/V (OR = 5.99), compared to other mothers, was associated with increased odds of their child eating F/V. Children with lower BMI (vs. higher BMI) were more likely to consume F/Vs when their mothers encouraged them to eat F/V (OR = 0.74). These findings suggest that maternal support may have a strong and immediate effect on children's F/V consumption. Theoretical models on behavior change should consider how explanatory factors, such as parental support, may vary at the momentary level. Boosting maternal support at the momentary level may be a critical component of future mobile-based interventions to address childhood obesity.

How to increase community participation capacity in food environment policymaking: Results of a scoping review

Background: Food environment plays a major role in health outcomes. A growing interest in community-based participatory research (CBPR) has led to its application in the improvement of the food environment. This scoping review aims to compile and map the literature and identify key strategies used for increasing community participation capacity in the food environment policymaking process.

Methods: The scoping review of peer-reviewed articles on community participation and food environment policymaking followed the framework suggested by Arksey and O'Malley (2005). Scopus, PubMed, and Web of Science were searched. A charting table was developed to extract the key information of each identified study. A directed content analysis approach was used to assign retrieved codes into categories proposed by Foster-Fishman.

Results: A total of 28 studies were included in this review. Most studies used the CBPR approach to involve the community at least in the problem identification step of the policymaking process (n=12) and 7 studies reported their involvement in all the steps of policymaking. In 15 out of 28 studies, the level of community participation was at "involvement" and in 8 studies it was at "empowerment". Strategies for increasing relational capacity, member capacity, programmatic capacity, and organizational capacity of community participation were reviewed.

Conclusion: To improve food environment using the community-participation approach, identifying different strategies and adjusting them based on the social and political context of each society is of high importance.

Interventions for increasing fruit and vegetable consumption in children aged five years and under

BACKGROUND

Insufficient consumption of fruits and vegetables in childhood increases the risk of future non-communicable diseases, including cardiovascular disease. Testing the effects of interventions to increase consumption of fruit and vegetables, including those focused on specific child-feeding strategies or broader multicomponent interventions targeting the home or childcare environment is required to assess the potential to reduce this disease burden.

OBJECTIVES

To assess the effectiveness, cost effectiveness and associated adverse events of interventions designed to increase the consumption of fruit, vegetables or both amongst children aged five years and under.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase and two clinical trials registries to identify eligible trials on 25 January 2020. We searched Proquest Dissertations and Theses in November 2019. We reviewed reference lists of included trials and handsearched three international nutrition journals. We contacted authors of included trials to identify further potentially relevant trials.

SELECTION CRITERIA

We included randomised controlled trials, including cluster-randomised controlled trials and cross-over trials, of any intervention primarily targeting consumption of fruit, vegetables or both among children aged five years and under, and incorporating a dietary or biochemical assessment of fruit or vegetable consumption. Two review authors independently screened titles and abstracts of identified papers; a third review author resolved disagreements.

DATA COLLECTION AND ANALYSIS

Two review authors independently extracted data and assessed the risks of bias of included trials; a third review author resolved disagreements. Due to unexplained heterogeneity, we used random-effects models in meta-analyses for the primary review outcomes where we identified sufficient trials. We calculated standardised mean differences (SMDs) to account for the heterogeneity of fruit and vegetable consumption measures. We conducted assessments of risks of bias and evaluated the quality of evidence (GRADE approach) using Cochrane procedures.

MAIN RESULTS

We included 80 trials with 218 trial arms and 12,965 participants. Fifty trials examined the impact of child-feeding practices (e.g. repeated food exposure) in increasing child vegetable intake. Fifteen trials examined the impact of parent nutrition education only in increasing child fruit and vegetable intake. Fourteen trials examined the impact of multicomponent interventions (e.g. parent nutrition education and preschool policy changes) in increasing child fruit and vegetable intake. Two trials examined the effect of a nutrition education intervention delivered to children in increasing child fruit and vegetable intake. One trial examined the impact of a child-focused mindfulness intervention in increasing vegetable intake. We judged 23 of the 80 included trials as free from high risks of bias across all domains. Performance, detection and attrition bias were the most common domains judged at high risk of bias for the remaining trials. There is low-quality evidence that child-feeding practices versus no intervention may have a small positive effect on child vegetable consumption, equivalent to an increase of 5.30 grams as-desired consumption of vegetables (SMD 0.50, 95% CI 0.29 to 0.71; 19 trials, 2140 participants; mean post-intervention follow-up = 8.3 weeks). Multicomponent interventions versus no intervention has a small effect on child consumption of fruit and vegetables (SMD 0.32, 95% CI 0.09 to 0.55; 9 trials, 2961 participants; moderate-quality evidence; mean post-intervention follow-up = 5.4 weeks), equivalent to an increase of 0.34 cups of fruit and vegetables a day. It is uncertain whether there are any short-term differences in child consumption of fruit and vegetables in meta-analyses of trials examining parent nutrition education versus no intervention (SMD 0.13, 95% CI -0.02 to 0.28; 11 trials, 3050 participants; very low-quality evidence; mean post-intervention follow-up = 13.2 weeks). We were unable to pool child nutrition education interventions in meta-analysis; both trials reported a positive intervention effect on child consumption of fruit and vegetables (low-quality evidence). Very few trials reported long-term effectiveness (6 trials), cost effectiveness (1 trial) or unintended adverse consequences of interventions (2 trials), limiting our ability to assess these outcomes. Trials reported receiving governmental or charitable funds, except for four trials reporting industry funding.

AUTHORS' CONCLUSIONS

Despite identifying 80 eligible trials of various intervention approaches, the evidence for how to increase children's fruit and vegetable consumption remains limited in terms of quality of evidence and magnitude of effect. Of the types of interventions identified, there was moderate-quality evidence that multicomponent interventions probably lead to, and low-quality evidence that child-feeding practice may lead to, only small increases in fruit and vegetable consumption in children aged five years and under. It is uncertain whether parent nutrition education or child nutrition education interventions alone are effective in increasing fruit and vegetable consumption in children aged five years and under. Our confidence in effect estimates for all intervention approaches, with the exception of multicomponent interventions, is limited on the basis of the very low to low-quality evidence. Long-term follow-up of at least 12 months is required and future research should adopt more rigorous methods to advance the field. This is a living systematic review. Living systematic reviews offer a new approach to review updating, in which the review is continually updated, incorporating relevant new evidence as it becomes available.

The neighborhood food environment modifies the effect of the 2009 WIC food package change on childhood obesity in Los Angeles County, California

Background

Food packages provided by the Special Supplemental Nutrition Program for Women, Infants and Children (WIC) were revised in 2009 to better align them with the Dietary Guidelines for Americans. This study was conducted to evaluate whether the effect of the food package change on childhood obesity varied by the food environment in the neighborhoods where WIC-participating children live.

Methods

Administrative data from participating children in Los Angeles County, California (2003–2016) were merged with geocoded food vendor information by neighborhood of residence. Obesity risk at age 4 was compared between children receiving old (2003–2009) and new (2010–2016) WIC food packages using sex-stratified Poisson regression models, with interaction terms between WIC package and neighborhood density (number per square mile) of healthy and unhealthy food outlets.

Results

The new food package was associated with a significant decrease in obesity risk. Among boys, the new food package was associated with 8 to 18% lower obesity risk at all healthy and unhealthy food outlet densities, and the association was not modified by neighborhood food outlet density. Among girls, the association of the new food package with obesity risk was protective in neighborhoods with high healthy and low unhealthy food outlet densities, and adverse in neighborhoods with high unhealthy and low healthy food outlet densities. The effect of the new food package among girls was modified by unhealthy food outlet density, with significantly smaller (p-value = 0.004) decreases in obesity risk observed in neighborhoods with higher unhealthy food outlet density.

Conclusions

The impact of the food package change was modified by the neighborhood food environment among girls only. Future policy changes should incorporate consideration of ways to mitigate potentially inequitable geographic distribution of the health benefits of policy changes.

Translation of two healthy eating and active living support programs for parents of 2-6 year old children: a parallel partially randomised preference trial protocol (the 'time for healthy habits' trial)

Background

Parents are key decision makers and role models in establishing and maintaining healthy behaviours in their children. Interventions involving parents have been shown to be more effective than those that do not, but there are barriers to participation. Efficacy trials have previously been conducted on two such parent-focussed healthy eating and active living interventions with the potential to overcome these barriers - Healthy Habits (telephone-based) and Time2bHealthy (online) with promising results. Further research is now required to determine the effectiveness of these interventions in a real-world context. The Time for Healthy Habits study is a 3-arm partially randomised preference trial which aims to evaluate the effectiveness and cost-effectiveness of two theory-based programs to promote healthy eating and appropriate levels of movement behaviours (physical activity, sedentary behaviour and sleep) for parents of 2- to 6-year-old children (Healthy Habits Plus telephone-based program and Time2bHealthy online program), when compared to a comparison group receiving written materials.

Methods

Participants will be recruited across five Local Health Districts in New South Wales, Australia. The partially randomised preference design initially allows for participants to decide if they wish to be randomised or opt to select their preferred intervention and has been recommended for use to test effectiveness in a real-world setting. Both interventions incorporate multiple behaviour change techniques and support parents to improve their children’s healthy eating, and movement behaviours (physical activity, sedentary behaviour and sleep) and run for 12 weeks, followed by a 3-month and 9-month post-baseline follow-up. Participants will also be asked to complete a process evaluation questionnaire at the completion of the intervention (3-months post-baseline). Outcomes include fruit and vegetable intake (primary outcome), non-core food intake, weight status, physical activity, sedentary behaviour, and sleep habits.

Discussion

To our knowledge, this is the first translational research trial evaluating the effectiveness and cost-effectiveness of a healthy eating and active living intervention in the 2- to 6-years age group. The results will build the evidence base in regard to translation of effective childhood obesity prevention interventions and inform the implementation and delivery of community based childhood obesity prevention programs.

Using a Socioecological Approach to Identify Factors Associated with Adolescent Sugar-Sweetened Beverage Intake

BACKGROUND

Adolescents are among the highest consumers of sugar-sweetened beverages (SSBs) in the United States. More research is needed to understand the relationship of multiple levels of influence on adolescent SSB intake across the socioecological model in a nationally representative sample.

OBJECTIVE

This secondary analysis of cross-sectional data aims to explain variance in adolescent SSB intake by exploring the associations of adolescent demographic (ie, age, race/ethnicity, and parent socioeconomic status), intrapersonal (ie, behavioral intention, self-efficacy, and media perception), interpersonal (ie, social norms and perceived parenting practices), and home availability variables.

DESIGN

This study included 1,560 adolescents who participated in the 2014 National Cancer Institute-sponsored cross-sectional Family, Life, Activity, Sun, Health, and Eating study. Descriptive statistics, analyses of variance, and stepwise multiple linear regression models were used to explore factors associated with SSB intake. In the stepwise regression, a 4-step model was analyzed with each subsequent step adding variables from different socioecological model levels.

RESULTS

The final step that included 14 variables individually associated with SSB intake significantly predicted 16.5% of the variance in SSB intake. Four variables were associated with higher SSB intake in the final step when controlling for all other variables: male sex (β=.066), non-Hispanic black vs non-Hispanic white (β=.123), adolescent's report of having parents allow them to have SSBs on a bad day (β=.150), and home SSB availability (β=.263). Race/ethnicity other than Hispanic and/or non-Hispanic black vs non-Hispanic white was associated with lower intake (β= -.092).

CONCLUSIONS

When considering potential targets for multilevel behavioral interventions aimed at reducing adolescent SSB intake, emphasis on reducing SSB availability at home may be especially important. Furthermore, although adolescence is a period of increasing independence, parent influence on adolescent's health behaviors may also be a key intervention target. Home and parental SSB factors may be more important than targeting intrapersonal factors and social norms among adolescents.

Nutrition Education in the Australian New South Wales Primary School Curriculum: Knowledge and Attitudes of Students and Parents

In NSW, Australia, the views of primary-school aged children and their parents in regard to the importance of nutrition education at school are unclear. The aim of the current study was to explore children’s knowledge of nutrition and eating habits and to identify gaps that future school nutrition education programs could target. Students aged 9 to 12 years and their parents (n = 21 dyads) were invited to participate in semi-structured interviews, complete a nutrition knowledge questionnaire, and perform a “healthy-unhealthy” food sorting task in a University food laboratory. Among the children, nutrition knowledge scores concerning “serves & portions” of common foods were lowest, identifying a gap in knowledge related to portion size. All children categorized fruits, vegetables, cola, and water correctly as “healthy” or “unhealthy” in the sorting task, but not for the sausage and muesli bar, suggesting that further support categorising processed foods may be needed. The interviews indicated that parents do actively try to teach their children about nutrition, although they reported feeling uncertain about their own level of nutrition knowledge. Children and parents indicated that there is very little nutrition education in school and more is needed. This research could be used to inform future curriculum components related to nutrition education for primary school children.

Investigating the relationship between parental weight stigma and feeding practices

Promoting a healthy diet in children remains a prominent public health priority. Parents have been shown to be a major influence on their children's eating behaviors, but limited research has been devoted to exploring the factors that lead parents to select certain feeding practices over others. Past research has demonstrated a link between weight stigma (i.e., prejudicial attitudes or discriminatory behavior targeted at individuals who carry excess weight) and an individual's own weight-related behaviors and outcomes, but no study has examined how parental levels of weight stigma maybe associated with a parent's preferred feeding practices. The primary objective of this study was to examine the cross-sectional associations between parental levels of weight-based stigmatization with parental feeding practices. Responses were collected on Amazon's Mechanical Turk website for n = 406 parents who 1) had at least one child aged 5-10 and 2) perceived themselves to be overweight or obese. After adjusting for relevant covariates, parental weight stigma was shown to be significantly associated with restrictive feeding practices, and verbal modeling of eating behaviors (all ps < .05). A priori exploratory mediation analysis identified concern about child weight as a significant mediator between weight stigma and parental feeding practices. A discussion of the potential limitations of this study, future directions of research, and implications of these findings are included.

Perceptions of Processed Foods Among Low-Income and Immigrant Parents

Background. Parent-aimed guidance on the topic of processed foods may help limit highly processed foods in children's diets, but little is known about parent understanding and perceptions of these products. Aims. To determine how parent perceptions of processing align with processing classification systems used in research, and to identify opportunities for future research in communicating information about processed foods. Method. Six focus groups with lower income, racial/ethnic minority and immigrant parents of fourth to sixth graders (n = 37) were conducted. Parents were asked to discuss their views on terminology related to food processing, classification of foods according to their processing level, the healthfulness of select foods, and criteria for choosing snacks for their children. Focus groups were guided by a thematic approach. NVivo 12 (QSR International) was used to facilitate analyses. Results. Thirty mothers and seven fathers participated. Two thirds (62%) were foreign-born; 38% identified as Hispanic. The term "processing" lacked consistent meaning among parents, with variation by immigrant status. Participants associated highly processed foods with convenience, packaging, and added ingredients; "less-processed" versions of foods (e.g., fresh; homemade) were perceived as healthier. Children's preferences were the main criteria for choosing snacks. Foreign-born parents were more likely to associate processed foods with positive characteristics (e.g., properly cooked). Conclusion. The concept of food processing is an area of misconception among parents, providing an opportunity for education that may be extended to larger audiences. A universally accepted definition of food classification by processing level is necessary to effectively communicate the link between processing and healthfulness.

Open Campus Policies: How Built, Food, Social, and Organizational Environments Matter for Oregon's Public High School Students' Health

Open campus policies that grant access to the off-campus food environment may influence U.S. high school students’ exposure to unhealthy foods, yet predictors of these policies are unknown. Policy holding and built (walkability), food (access to grocery stores), social (school-to-neighborhood demographic similarity), and organizational (policy holding of neighboring schools) environment data were collected for 200 Oregon public high schools. These existing data were derived from the Oregon School Board Association, WalkScore.com, the 2010 Decennial Census, the 2010–2014 American Community Survey, the Supplemental Nutrition Assistance Program, TDLinex, Nielson directories, the U.S. Department of Education, the National Center for Education Statistics, and the Common Core of Data. Most (67%) of Oregon public high schools have open campus policies. Logistic regression analyses modeled open campus policy holding as a function of built, food, social, and organizational environment influences. With health and policy implications, the results indicate that the schools’ walkability, food access, and extent of neighboring open campus policy-schools are significantly associated with open campus policy holding in Oregon.

Sleeping Time, BMI, and Body Fat in Chinese Freshmen and Their Interrelation

INTRODUCTION

In the past two decades, urbanization in many Asian countries has led to sedentary lifestyle and overnutrition, which has set the stage for the epidemic of obesity. Those who have obesity during adolescence usually have obesity into adulthood, which causes many medical and psychological issues that can result in premature death. Recent data suggest that short sleep duration may contribute to the risk of obesity, opening a new avenue for potential intervention. The aim of this study was to describe the prevalence of sleeping time, body mass index (BMI), and fat mass in Chinese freshmen and to indicate the relationship among them.

METHODS

We conducted a cross-sectional study consisting of 1,938 freshmen aged from 18 to 24 years, including 684 (35.3%) men and 1,254 (64.7%) women. BMI, sleeping time, and other potential related variables were collected by questionnaire. Obesity and overweight were defined as BMI ≥28.0 and ≥24.0, respectively. All students were divided into three groups according to the tertiles of body fat percentage (Fat%), which were measured by bioelectrical impedance analysis. Sleeping time was divided into 3 categories based on the duration, <6, 6-8, and >8 h per day.

RESULTS

Participants who slept longer had lower BMI and Fat%. Sex, diet control, and maternal obesity were all significantly associated with BMI or Fat% after adjustment. There were significant differences between sleeping time <6 and >8 h in both overweight group and Fat% tertiles independent of adjustment used. The significant difference between sleeping time 6-8 and >8 h only existed in overweight group, while irrelevant relation was observed in both models of obesity group.

CONCLUSION

Longer sleeping time was associated with a lower BMI in Chinese freshmen, even after adjustment for multiple confounders. The overweight stage is a critical period of weight management intervention by changing sleeping time. If adolescents have entered the obesity stage, the effect size of lifestyle intervention might be significantly limited.
