Household food insecurity and its association with overweight and obesity in children aged 2 to 14 years

Acceptability and satisfaction of a mindfulness-based healthy eating and stress management program targeting economically marginalized families in a pilot trial

OBJECTIVES

To inform and improve future program development, particularly with economically marginalized families, this study aimed to examine the acceptance and satisfaction of a mindfulness-based healthy eating and stress management program among participating parents and daycare teachers in a pilot trial.

METHODS

A mixed-methods study was conducted to evaluate a 14-week mindfulness-based program implemented with 107 English-speaking Head Start children (ages 3-5 years) and their parents. The program included a school-based mindful eating curriculum, a home-based parent component to promote mindful eating and reduce parental stress, and a bridging activity connecting home practice with school learning. Quantitative evaluation data were collected from 84 parents (Mage = 30.12 years) and 12 teachers (Mage = 43.92 years) via Qualtrics. Semistructured interviews were conducted with 20 parents (Mage = 31.55 years). Descriptive statistics and thematic analysis were used to analyze data.

RESULTS

Both quantitative (95.2%) and qualitative data demonstrated overall satisfaction with the entire program. About 83%-92% of teachers and 85% of parents considered the school-based curriculum to be satisfactory and acceptable. About 88%-100% of parents were satisfied with the Facebook private group and parent meetings. Approximately 91% of parents found the child letters helpful in connecting and translating school learning into mindful practices at home.

CONCLUSIONS

Results demonstrate high levels of acceptance and satisfaction with the mindfulness-based program among economically marginalized families and daycare teachers. Findings provide several key implications for future interventions to incorporate a mindful eating curriculum into daycare routines, proactively connect home practices with school learning to enhance the interactive influence between children and parents, and form a virtual peer support community through social media platforms and group meetings.

Maternal nutrition literacy and childhood obesity in food-insecure and secure households

This study examined whether maternal nutrition knowledge could help reduce the risk of obesity in children from food-insecure households compared to those from food-secure households. This cross-sectional study was performed on 327 mothers and their children. The children, aged 6-12 years, were recruited from primary schools throughout Shiraz, Iran. Food-insecurity and nutrition literacy were assessed using the Household Food-insecurity Access Scale (HFIAS) and a 60-item Food and Nutrition Literacy Assessment Tool (FNLAT), respectively. Logistic regression models were used to examine the association between children's overweight/obesity and maternal food and nutritional literacy (FNL) across food-secure households and those facing varying degrees of food-insecurity. One hundred thirty-three participants were classified as mild, 28 as moderate, and 7 as severely food-insecure. The results showed that maternal FNL was significantly associated with a reduced risk of overweight/obesity in children (odds ratio (OR) 0.29, 95% confidence intervals (CI) 0.17-0.51). Only moderate/severe food-insecurity was associated with overweight/obesity (OR 4.64, 95% CI 1.75-12.29). Both in food-secure and food-insecure households, good FNL was associated with a significant reduction in overweight/obesity risk compared to poor FNL. The findings suggest that nutrition education programs may be particularly beneficial for children living in food-insecure households, and that these programs should be tailored to address the specific needs of this population.

Association of household food insecurity with diet quality in a nationally representative sample of United States toddlers: a cross-sectional study

BACKGROUND

Although previous research has shown that food insecurity adversely affects diet quality in adults, this relationship is less consistently observed in children. However, studies in children have focused on those aged 2 y or older and the association of food insecurity with diet quality in children aged 12-23 mo is unclear.

OBJECTIVES

The objective was to determine the association of household food insecurity with diet quality, as indicated by Healthy Eating Index-Toddlers-2020 (HEI-Toddlers-2020), in United States children aged 12-23 mo.

METHODS

The study used a cross-sectional design based on data from 2013-2014, 2015-2016, and 2017-March 2020 survey cycles of National Health and Nutrition Examination Survey. The primary sample included 708 children aged 12-23 mo with 1) complete data on food security, assessed via the United States Food Security Survey Module (USFSSM); 2) ≥1 d of reliable 24-h dietary recall data; and 3) reported energy intake from complementary foods/beverages (that is, foods and beverages other than human milk or infant formula). On the basis of responses to USFSSM, households were classified as food secure or food insecure. Proxies, typically parents, reported child's dietary intake. Diet quality was assessed using the HEI-Toddlers-2020. Linear regression analyses examined the association of household food security status with HEI-Toddlers-2020 total and component scores, adjusted for demographic characteristics.

RESULTS

Household food insecurity was significantly associated with lower HEI-Toddlers-2020 total score (estimate = -3.78; standard error = 1.06; P = 0.0007), as well as lower component scores for whole fruits (estimate = -0.56; standard error = 0.18; P = 0.003), and whole grains (estimate = -0.85; standard error = 0.35; P = 0.02).

CONCLUSIONS

The association of household food insecurity with lower diet quality in this study suggests that toddlers may not be shielded from household food shortages. Although consumption of certain food groups, such as whole grains, was inadequate in the overall sample of United States toddlers, food insecurity could exacerbate suboptimal intake of whole grains. Interventions to improve diet quality of young children must account for household food insecurity.

Next Steps in Efforts to Address the Obesity Epidemic

Obesity prevalence continues to rise globally at alarming rates, with adverse health and economic implications. In this state-of-the-art review, we provide an analysis of selected evidence about the current knowledge in the obesity literature, including a synthesis of current challenges in obesity and its determinants. In addition, we review past and current efforts to combat the obesity epidemic, highlighting both successful efforts and areas for further development. Last, we offer insights into the next steps to address the obesity epidemic and advance the field of obesity through both research and practice by (a) adopting a systems perspective, (b) fostering cross-sector and community collaborations, (c) advancing health equity, (d) narrowing the research-to-practice and research-to-policy gaps with multidisciplinary approaches, and (e) embracing complementary approaches for concurrent obesity prevention and treatment.

Proportion of food insecurity and its sociodemographic correlates among Spanish adolescents: the EHDLA study

Introduction

Insufficient and unequal access to food (i.e. food insecurity [FI]) has a negative impact on health, especially in vulnerable groups such as adolescents. This study determined the prevalence of FI and its sociodemographic correlates among adolescents in the Valle de Ricote, Region of Murcia, Spain.

Methods

A secondary analysis was conducted using data from the Eating Healthy and Daily Life Activities (EHDLA) study, which provides a sample of 882 adolescents (median = 14, interquartile range [IQR] = 2) collected during the 2021-2022 academic year. FI was measured using the Child Food Security Survey Module in Spanish (CFSSM-S).

Results

Findings showed a prevalence of FI of 16.2%, with significant sociodemographic disparities. Adolescents from immigrant (n: 67; %: 46.9; odds ratio [OR] = 2.41; 95% CI: 1.38 to 4.21) and diverse (n: 25; %: 17.5; OR=2.04; 95% CI: 1.10 to 3.79) families showed a higher susceptibility to FI. In addition, higher parental education was related to lower FI (university education: n: 13; %: 9.6; OR=0.36; 95% CI: 0.17 to 0.74).

Conclusion

These findings highlight the need for targeted public health policies that improve access to nutritious food, enhance parental education, and address socioeconomic inequalities to effectively reduce FI among Spanish adolescents.

Clustering Patterns of Unhealthy Lifestyle Behaviours Among Adolescents: A Multilevel Analysis of a Nationally Representative School-Based Survey from 73 Countries

Background: Adolescence is a crucial stage when young people adopt various lifestyle behaviours that can impact their health. However, the broader determinants of these behaviours remain underexplored. This study aimed to investigate clustering patterns of lifestyle behaviours, including physical activity, sedentary behaviour, and dietary habits, among adolescents and examine their determinants across individual, community, and societal levels. Methods: This study utilised nationally representative Global School-based Student Health Survey data. The lifestyle behaviours were dichotomised based on specific definitions, and the clustering patterns of multiple unhealthy behaviours were compared at various levels of factors. Multilevel logistic regression analysis was employed to identify individual, community, and societal level determinants of multiple unhealthy behaviours. Results: The study included 293,770 adolescents from 73 countries and territories across five World Health Organization (WHO) regions. The overall prevalence of one, two, three, four, and five unhealthy behaviours was 6.9%, 29.9%, 36.5%, 21.5%, and 4.5%, respectively. The odds of multiple unhealthy behaviours (defined by ≥4) increase with age and are higher among female adolescents [(AOR: 1.06, 95% CI:1.05, 1.07); (AOR: 1.16, 95% CI: 1.14, 1.19)], respectively. Adolescents from supportive families, peer environments, or food-secure households had lower odds of engaging in these behaviours [(AOR: 0.84, 95% CI: 0.82, 0.86); (AOR: 0.96, 95% CI: 0.94, 0.98); (AOR: 0.91, 95% CI: 0.87, 0.95)], respectively. The odds of exhibiting multiple unhealthy behaviours were significantly higher among adolescents in countries with high (0.7-0.79) and very high (0.8-1.0) Human Development Indexes (HDI) compared to those in low (<0.55) HDI countries [(AOR: 1.84, 95% CI: 1.16, 2.94); (AOR: 3.00, 95% CI: 1.48, 6.08)], respectively. Conclusion: The study findings reveal that multiple unhealthy lifestyle behaviours, including insufficient physical activity, sedentary behaviour, inadequate fruit and vegetable consumption, frequent soft drink intake, and fast-food consumption, are globally prevalent among adolescents. These behaviours have distinct clustering patterns associated with individual characteristics, family and peer environments, and broader socio-economic and societal contexts.

Household food insecurity and its association with diet quality in high-risk children

The aim of this study was to evaluate the association between dietary practices and household food insecurity (HFI) status among high-risk children during the COVID-19 pandemic. This cross-sectional study was conducted with 147 children aged 1 to 9 attending at three reference health centers in the city of Rio de Janeiro. Diet quality data was assessed using Healthy Eating Indices. The Brazilian Scale of Food and Nutrition Insecurity measured HFI status. Associations between HFI and dietary practices were assessed using logistic regression models. Almost half of the children lived with food insecurity (47.6%). HFI was associated with deteriorated diet quality, evidenced by the increased weekly frequency of consumption of ultra-processed foods (UPF), such as sugar-sweetened beverages and processed meats, and reduced frequency of fruits and vegetables. Parents perceived a reduction in meat and milk consumption and an increase in the intake of UPF among households of children in HFI throughout the pandemic. Our results suggest that HFI status was associated with deterioration in diet quality during the critical phase of social isolation.

Grocery intervention and DNA-based assessment to improve diet quality in pediatric obesity: a pilot randomized controlled study

OBJECTIVE

We assessed the impact of a food-provisioning intervention on diet quality in children with obesity.

METHODS

Participants (n = 33, aged 6-11 years) were randomly assigned to either usual care (intensive health behavior and lifestyle treatment) or intervention (usual care + food provisioning; high-fiber, low-dairy diet) for 4 weeks. The primary outcome was a change in child diet quality at Week 4. Secondary outcomes were changes in weight, food insecurity, gut microbiome composition (16S ribosomal RNA), and dietary intake, measured via an objective DNA-based biomarker (i.e., FoodSeq). Genomic dietary data were analyzed against a larger pediatric adolescent obesity cohort (n = 195, aged 10-18 years) from similar households.

RESULTS

Intervention demonstrated changes across all assessed diet components and was more effective than usual care in increasing whole grain (β = 0.20, 95% CI: 0.05 to 0.34; p = 0.013) and fiber (β = 2.52, 95% CI: 1.28 to 3.76; p < 0.001) and decreasing dairy (β = -1.31, 95% CI: -2.02 to -0.60; p = 0.001). FoodSeq results, highly concordant with grocery orders (adjusted R2 = 0.65; p < 0.001), indicated a dietary shift toward low-energy-density plant taxa in the intervention relative to a prior survey of diet in a related cohort (β = 8.64, 95% CI: 5.18 to 12.14; p < 0.001). No significant changes were observed in microbiome, weight, or food insecurity.

CONCLUSIONS

Our study supports the potential of dietitian-guided food provisioning for improving diet quality in children with obesity and demonstrates an objective genomic approach for evaluating dietary shifts.

Predicting food insecurity in a pediatric population using the electronic health record

Introduction

More than 5 million children in the United States experience food insecurity (FI), yet little guidance exists regarding screening for FI. A prediction model of FI could be useful for healthcare systems and practices working to identify and address children with FI. Our objective was to predict FI using demographic, geographic, medical, and historic unmet health-related social needs data available within most electronic health records.

Methods

This was a retrospective longitudinal cohort study of children evaluated in an academic pediatric primary care clinic and screened at least once for FI between January 2017 and August 2021. American Community Survey Data provided additional insight into neighborhood-level information such as home ownership and poverty level. Household FI was screened using two validated questions. Various combinations of predictor variables and modeling approaches, including logistic regression, random forest, and gradient-boosted machine, were used to build and validate prediction models.

Results

A total of 25,214 encounters from 8521 unique patients were included, with FI present in 3820 (15%) encounters. Logistic regression with a 12-month look-back using census block group neighborhood variables showed the best performance in the test set (C-statistic 0.70, positive predictive value 0.92), had superior C-statistics to both random forest (0.65, p < 0.01) and gradient boosted machine (0.68, p = 0.01), and showed the best calibration. Results were nearly unchanged when coding missing data as a category.

Conclusions

Although our models could predict FI, further work is needed to develop a more robust prediction model for pediatric FI.

Association of household food insecurity with sociodemographic factors and obesity in US youth: findings from the National Health and Nutrition Examination Survey 2017-2018

Background

The objective is to determine the prevalence of household food insecurity (HFI) based on sociodemographic factors and their relationship to obesity in youth.

Methods

The study included a sample of 1,962 youth (aged 6-18) from the National Health and Nutrition Examination Survey (NHANES). The US Household Food Security Survey Module is used to measure food security over the past 12 months. Logistic regression models were used to estimate adjusted odds ratios (ORs) while controlling for covariates.

Results

In total, 27.4% of the individuals surveyed experienced HFI. Youth from food insecure households were more likely to be obese (adjusted odds ratio [aOR]: 1.59 [95% confidence interval: 1.19-2.13]) and also having abdominal obesity (aOR: 1.56 [95% CI: 1.19-2.03]). however, factors such as non-Hispanic ethnicity, having a Head of household with a college degree, and households with an income exceeding 350% of the poverty line were associated with a reduced risk of facing HFI.

Conclusion

Hispanic individuals, households with lower parental education levels, and lower family incomes, are disproportionately affected by food insecurity. Furthermore, HFI has been associated with an increased risk of overweight and abdominal obesity among youth. Addressing FI requires targeted policies and interventions that prioritize vulnerable groups.

Household food insecurity among child and adolescent athletics practitioners: A cross-sectional, descriptive, and exploratory study

OBJECTIVE

The aim of the study was to explore the prevalence of food insecurity among child and adolescent athletics practitioners and to investigate factors associated with exercise performance, dietary habits, body composition, sleep, and socioeconomic status based on food security status.

METHODS

This was a cross-sectional, descriptive, and exploratory study conducted in Campinas, São Paulo, Brazil, between June and July 2023. The convenience sample included children and adolescents (7-17 y old) of both sexes. We evaluated exercise performance, household food insecurity (HFI), dietary-related parameters, and other body composition, lifestyle, and social-related variables. Exercise performance was assessed using the counter movement jump (CMJ), squat jump (SJ), horizontal long jump (HLJ), 50-m sprint test (50-m ST) and throwing strength test (TST). The assessment of HFI was conducted using the food insecurity experience scale (FIES). Comparisons and associations were investigated based on food security status.

RESULTS

The total sample size was comprised of 138 children (n = 42; 30.4%) and adolescents (n = 96; 69.6%). We found an association between food security status and sex (X2(138,1) = 4.42; P = 0.036). SJ was higher in the food security group than in the HFI group (t(117) = 2.112; P = 0.037; ES = 0.39). Sleep- and dietary-related factors did not differ between the groups.

CONCLUSIONS

In summary, the prevalence of HFI among child and adolescent athletics participants was approximately 40%. Regarding exercise performance, SJ was better in the food security group than in the HFI group. Concerning dietary-related data, the HFI group had a lower number of meals per day than the food security group, and other dietary data did not differ between the groups. Body composition and sleep-related parameters were similar between the groups.

Lifestyle Clusters of Diet Quality, Sleep, and Screen Time and Associations with Weight Status in Children from Madrid City: ENPIMAD Study

BACKGROUND

Childhood overweight and obesity is a global concern and has increased in Spain over the last decades. Combinations of lifestyle behaviors (i.e., diet, sleep, and sedentarism) are highly related to weight status. Therefore, this study aimed to identify lifestyle patterns among children from Madrid City, and analyze associations with the prevalence of overweight, obesity, and abdominal obesity, considering socio-economic factors.

METHODS

A cross-sectional analysis was conducted on 4545 children from the ENPIMAD study with data on diet, sleep, anthropometric, and socio-economic variables. K-means cluster analysis was used to identify lifestyle clusters, and logistic regressions were used to examine the associations between socio-economic indicators and cluster membership, and between clusters and weight status.

RESULTS

Findings show three lifestyle clusters (healthy, mixed, and unhealthy), with boys and older children more represented in the unhealthy cluster. Food insecurity and low socio-economic status were associated with unhealthier clusters in boys and girls. Children in unhealthier clusters were more likely to have obesity and abdominal obesity. However, these associations disappeared in girls after controlling for food insecurity.

CONCLUSION

These results provide insight into the combination of behaviors and socio-economic factors associated with childhood obesity that may aid in the design of future interventions.

Maternal Western-style diet programs skeletal muscle gene expression in lean adolescent Japanese macaque offspring

Early-life exposure to maternal obesity or a maternal calorically dense Western-style diet (WSD) is strongly associated with a greater risk of metabolic diseases in offspring, most notably insulin resistance and metabolic dysfunction-associated steatotic liver disease (MASLD). Prior studies in our well-characterized Japanese macaque model demonstrated that offspring of dams fed a WSD, even when weaned onto a control (CTR) diet, had reductions in skeletal muscle mitochondrial metabolism and increased skeletal muscle insulin resistance compared to offspring of dams on CTR diet. In the current study, we employed a nested design to test for differences in gene expression in skeletal muscle from lean 3-year-old adolescent offspring from dams fed a maternal WSD in both the presence and absence of maternal obesity or lean dams fed a CTR diet. We included offspring weaned to both a WSD or CTR diet to further account for differences in response to post-weaning diet and interaction effects between diets. Overall, we found that a maternal WSD fed to dams during pregnancy and lactation was the principal driver of differential gene expression (DEG) in offspring muscle at this time point. We identified key gene pathways important in insulin signaling including PI3K-Akt and MAP-kinase, regulation of muscle regeneration, and transcription-translation feedback loops, in both male and female offspring. Muscle DEG showed no measurable difference between offspring of obese dams on WSD compared to those of lean dams fed WSD. A post-weaning WSD effected offspring transcription only in individuals from the maternal CTR diet group but not in maternal WSD group. Collectively, we identify that maternal diet composition has a significant and lasting impact on offspring muscle transcriptome and influences later transcriptional response to WSD in muscle, which may underlie the increased metabolic disease risk in offspring.

Household food insecurity and physical activity behaviour in Ecuadorian children and adolescents: findings from the Ecuador 2018 National Health and Nutrition Survey (ENSANUT-2018)

OBJECTIVE

Ecuador has a high prevalence of household food insecurity (HFI) and is undergoing nutritional and epidemiologic transition. Evidence from high-income countries has reported negative or null associations between HFI and physical activity (PA) in children. It remains uncertain whether the same is true of those from low- and middle-income countries like Ecuador whose environmental and socio-demographic characteristics are distinct from those of high-income countries. We aimed to investigate the association of HFI with PA, sedentary behaviour (SB) and anthropometric indicators in children.

DESIGN

Cross-sectional analysis of data from the nationally representative 2018 Ecuadorian National Health and Nutrition Survey. Data were collected on HFI, PA, SB, socio-demographic characteristics and measured height and weight. Unadjusted and adjusted linear, log-binomial and multinomial logistic regression analyses assessed the relationship of HFI with PA, SB, stunting and BMI-for-age.

SETTING

Ecuador.

PARTICIPANTS

23 621 children aged 5-17 years.

RESULTS

Marginal and moderate-severe HFI was prevalent in 24 % and 20 % of the households, respectively. HFI was not associated with PA, SB, stunting nor underweight. Moderate-severe HFI was associated with a lower odds of overweight and obesity. However, adjustment for household assets attenuated this finding for overweight (adjusted OR:0·90, 95 % CI: 0·77, 1·05) and obesity (adjusted OR: 0·88, 95 % CI: 0·71, 1·08).

CONCLUSION

HFI is a burden in Ecuadorian households, but is not associated with PA, SB nor anthropometric indicators in children aged 5-17 years. However, a concerning prevalence of insufficient PA was reported, emphasising the critical need for evidence-based interventions aimed at promoting PA and reducing SB.

The potential role of social care in reducing childhood obesity

PURPOSE OF REVIEW

This review evaluates the current evidence for relationships of social factors with childhood obesity and for a role of social care in reduction of childhood obesity.

RECENT FINDINGS

Most literature on the relationship between social factors and childhood obesity has examined food insecurity as a risk factor for obesity. Associations between food insecurity and excess weight in children are most consistent during infancy and among those with food insecurity at more than one time point. A few pilot food security interventions that link patients with produce or groceries show feasibility and potential promise for reducing childhood obesity risk factors. However, full-scale, randomized studies to examine interventions that reduce social needs and their effects on childhood obesity are lacking. Future research is needed to examine holistic social care approaches to effectively reduce childhood obesity risk factors.

SUMMARY

Food insecurity acts as a barrier to childhood obesity prevention and treatment. Patient-centered, validated measures of social needs and effective interventions to address social needs are needed to equitably prevent and treat childhood obesity.

Adolescent food insecurity in female rodents and susceptibility to diet-induced obesity

Food insecurity is defined as having limited or uncertain access to nutritious foods, and adolescent food insecurity is associated with obesity and disordered eating behaviors in humans. We developed a rodent model of adolescent food insecurity to determine whether adolescent food insecurity per se promotes increased susceptibility to diet-induced obesity and altered eating behaviors during adulthood. Female juvenile Wistar rats were singly housed and assigned to three experimental diets: food-secure with standard chow (CHOW), food-secure with a high-fat/sugar Western diet (WD), and food-insecure with WD (WD-FI). Food-secure rats (CHOW and WD) received meals at fixed feeding times (9:00, 13:00, and 16:00). WD-FI rats received meals at unpredictable intervals of the above-mentioned feeding times but had isocaloric amounts of food to WD. We investigated the impact of adolescent food insecurity on motivation for sucrose (Progressive Ratio), approach-avoidance behavior for palatable high-fat food (Approach-Avoidance task), and susceptibility to weight gain and hyperphagia when given an obesogenic choice diet. Secondary outcomes were the effects of food insecurity during development on anxiety-like behaviors (Open Field and Elevated Plus Maze) and learning and memory function (Novel Location Recognition task). Rodents with adolescent food insecurity showed a greater trend of weight gain and significantly increased fat mass and liver fat accumulation on an obesogenic diet in adulthood, despite no increases in motivation for sucrose or high-fat food. These data suggest that adolescent unpredictable food access increases susceptibility to diet-induced fat gain without impacting food motivation or food intake in female rodents. These findings are among a small group of recent studies modeling food insecurity in rodents and suggest that adolescent food insecurity in females may have long-term implications for metabolic physiology later in life.

Risk factors for household food insecurity in the Eastern Caribbean Health Outcomes Research Network cohort study

Background

Globally, 1.3 billion people were considered food insecure as of 2022. In the Caribbean region, the prevalence of moderate or severe food insecurity was 71.3% as of 2020, the highest of all subregions in Latin America. Experienced based measurement scales, like the Latin American and Caribbean Food Security Scale, are efficient measurement tools of food insecurity used globally. The Eastern Caribbean Health Outcomes Research Network (ECHORN) Cohort Study is a population-based longitudinal cohort study in the two Caribbean U.S. territories of Puerto Rico and the U.S. Virgin Islands, as well as in Barbados and Trinidad & Tobago. The purpose of this research was to examine the demographic, psychosocial, behavioral, and environmental risk factors associated with household food insecurity (HFI) among adults ≥40 years of age in the ECHORN cohort.

Methods

A cross-sectional analysis of baseline ECHORN cohort study data was conducted. The primary outcome was household food insecurity (none, mild, moderate/severe). A total of 16 known and potential risk factors were examined for their association with HFI. The ANOVA and chi-square statistics were used in bivariate analysis. Ordinal logistic regression was used for the multivariable and sex stratified analyses.

Results

More than one-quarter of the sample (27.3%) experienced HFI. In bivariate analyses, all risk factors examined except for sex, were significantly associated with HFI status. In the multivariable analysis, all variables except sex, education, marital status, smoking status, and residing in Puerto Rico were significant predictors of HFI in the adjusted model. In sex stratified analysis, depression, food availability, self-rated physical health, and island site were significantly associated with increased odds of worsening HFI for women, but not for men. Source of potable water was an important risk factor for both men and women.

Discussion

The prevalence of HFI in the ECHORN cohort study is comparable to other studies conducted in the region. While women did not have an increased risk of HFI compared to men, a different set of risk factors affected their vulnerability to HFI. More research is needed to understand how water and food security are interrelated in the ECHORN cohort.

Experiencing food insecurity in childhood: influences on eating habits and body weight in young adulthood

OBJECTIVE

To examine how food insecurity in childhood up to adolescence relates to eating habits and weight status in young adulthood.

DESIGN

A longitudinal study design was used to derive trajectories of household food insecurity from age 4·5 to 13 years. Multivariable linear and logistical regression analyses were performed to model associations between being at high risk of food insecurity from age 4·5 to 13 years and both dietary and weight outcomes at age 22 years.

SETTING

A birth cohort study conducted in the Province of Quebec, Canada.

PARTICIPANTS

In total, 698 young adults participating in the Québec Longitudinal Study of Child Development.

RESULTS

After adjusting for sex, maternal education and immigrant status, household income and type of family, being at high risk (compared with low risk) of food insecurity in childhood up to adolescence was associated with consuming higher quantities of sugar-sweetened beverages (ßadj: 0·64; 95 % CI (0·27, 1·00)), non-whole-grain cereal products (ßadj: 0·32; 95 % CI (0·07, 0·56)) and processed meat (ßadj: 0·14; 95 % CI (0·02, 0·25)), with skipping breakfast (ORadj: 1·97; 95 % CI (1·08, 3·53)), with eating meals prepared out of home (ORadj: 3·38; 95 % CI (1·52, 9·02)), with experiencing food insecurity (ORadj: 3·03; 95 % CI (1·91, 4·76)) and with being obese (ORadj: 2·01; 95 % CI (1·12, 3·64)), once reaching young adulthood.

CONCLUSION

Growing up in families experiencing food insecurity may negatively influence eating habits and weight status later in life. Our findings reinforce the importance of public health policies and programmes tackling poverty and food insecurity, particularly for families with young children.

Parents, but not their children, demonstrate greater delay discounting with resource scarcity

BACKGROUND

Individuals with obesity tend to discount the future (delay discounting), focusing on immediate gratification. Delay discounting is reliably related to indicators of economic scarcity (i.e., insufficient resources), including lower income and decreased educational attainment in adults. It is unclear whether the impact of these factors experienced by parents also influence child delay discounting between the ages of 8 and 12-years in families with obesity.

METHODS

The relationship between indices of family income and delay discounting was studied in 452 families with parents and 6-12-year-old children with obesity. Differences in the relationships between parent economic, educational and Medicaid status, and parent and child delay discounting were tested.

RESULTS

Results showed lower parent income (p = 0.019) and Medicaid status (p = 0.021) were differentially related to greater parent but not child delay discounting among systematic responders.

CONCLUSIONS

These data suggest differences in how indicators of scarcity influence delay discounting for parents and children, indicating that adults with scarce resources may be shaped to focus on immediate needs instead of long-term goals. It is possible that parents can reduce the impact of economic scarcity on their children during preadolescent years. These findings suggest a need for policy change to alleviate the burden of scarce conditions and intervention to modify delay discounting rate and to improve health-related choices and to address weight disparities.
