Associations between Japanese schoolchildren's involvement in at-home meal preparation, their food intakes, and cooking skills

Early life involvement in food skills is associated with children's cooking skills: a longitudinal analysis

Engaging young children in food skills such as food planning and preparation early in life may be an important predictor of later child cooking skills. The aim of this study was to examine whether early life involvement in food skills (mean age at baseline = 3.6 years) is prospectively associated with cooking skills among a sample of 60 children (mean age at follow-up = 10.0 years; 83% White) from the Guelph Family Health Study, an ongoing cohort study examining the effect of a home-based obesity prevention intervention. Early life involvement in food skills, i.e., child involvement in grocery shopping and meal preparation, was reported by parents at baseline. Children self-reported their cooking skills at follow-up. After adjusting for child age, child sex, parent age, household income, and intervention status, early life involvement in food skills was significantly associated with later child cooking skills (β = 0.24, 95% CI (0.02-0.45), p = 0.03). Future studies with larger and more socioeconomically, geographically, and racially diverse samples are needed to confirm these findings.

Cooking and Its Impact on Childhood Obesity: A Systematic Review

INTRODUCTION

This systematic review aimed to study the effect of a cooking intervention on obesity among children and adolescents aged < 18 years.

METHODS

Articles that studied the effect of cooking intervention with at least 4 sessions among children and adolescents on obesity (from January, 2000 to December, 2021) were included for analysis. Of the 500 articles identified through PubMed and ScienceDirect database, 9 studies qualified to be included in this review.

RESULTS

One-third of the studies found a positive effect of a cooking intervention on obesity among children and adolescents. School-based studies conducted among elementary school students were promising. Centers for Disease Control and Prevention body mass index percentile was the most common tool used to identify children and adolescents with overweight and obesity. The majority of the studies had a strong methodology.

DISCUSSION

All studies showed improvement in diet-related factors. Active participation of parents is crucial in making childhood interventions successful. It is difficult to delineate the effect of cooking alone on obesity as almost all studies had multicomponent interventions.

IMPLICATIONS FOR RESEARCH AND PRACTICE

These diverse results highlight the need for longitudinal studies in natural settings to comprehend the effect of long-term cooking on obesity in children and adolescents.

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.

Associations between Cooking at Home and Nutrient and Food Group Intake among Female University Students: A Cross-Sectional Analysis on Living Arrangements

This cross-sectional study examined the association between cooking frequency and nutrient and food group intake among female university students with different living arrangements in Japan. Nutrient and food group intakes were assessed using a validated, brief, self-administered diet history questionnaire. Cooking frequency was measured using a single question on a five-point scale. The questionnaire also asked about living arrangements. Of the 91 respondents, 75 females were analyzed. Regarding cooking frequency, cooking at least 1-2 days a week was classified as cooking, and the "cooking yet living with families" group was compared with the "not cooking and living with families" and "cooking and living alone" groups. Based on the intakes of the "cooking yet living with families" group, the "not cooking and living with families" group consumed more total fat (29.5% energy vs. 33.0% energy, p = 0.010) and fewer cereals (224.8 g/1000 kcal vs. 179.6 g/1000 kcal, p = 0.007), and the "cooking and living alone" group consumed more confectionaries (21.0 g/1000 kcal vs. 34.5 g/1000 kcal, p = 0.023). This study showed that female university students who cook at least once a week and live with their families may have better diet quality than those who do not cook and live with their families and those who cook and live alone.

Association between maternal adverse childhood experiences and child resilience and self-esteem: Results from the K-CHILD study

BACKGROUND

Previous studies have found that children of mothers with adverse childhood experiences (ACEs) are more likely to have adverse mental health outcomes. However, little is known about the role of other cognitive abilities, such as resilience and self-esteem, in how children deal with stressful situations.

OBJECTIVE

To examine the association between maternal ACEs and resilience and self-esteem in children.

PARTICIPANTS AND SETTING

The data was collected as part of the population-based Kochi Child Health Impact of Living Difficulty (K-CHILD) study in 2016. Participants included 2759 in first grade, 2878 in fifth grade, 3143 in eighth grade, and 3611 children in 11th grade living in Kochi Prefecture, Japan (N = 12,391).

METHODS

Maternal ACEs and covariates were reported by mothers. Mothers provided information regarding their children's resilience for children in the first, fifth, and eighth grades. Children in the fifth, eighth, and 11th grades reported their own self-esteem.

RESULTS

Children of mothers with a larger number of ACEs had lower levels of resilience (p for trend (i.e., linear associations) < 0.001) as well as lower levels of self-esteem (p for trend <0.001), adjusting for potential confounding variables. These associations became non-significant after adjusting for potential mediators, and the relationship was mediated by variables such as maternal psychological distress, current socioeconomic status, and parenting behaviors.

CONCLUSIONS

There was a significant dose-response relationship between the number of maternal ACEs and children's resilience and self-esteem, and this relationship may be mediated by maternal psychological distress, current socioeconomic status, and positive parenting behaviors. Further interventional studies that break the link between maternal ACEs and resilience and self-esteem should be conducted.

Perspectives of Black and Hispanic Children Living in Under-Resourced Communities on Meal Preparation and Grocery Shopping Behaviors: Implications for Nutrition Education

Minority children living in under-resourced communities are at the greatest risk for obesity and poor diet quality. Child involvement in meal preparation may be a helpful strategy to improve diet quality. This paper explores minority children's perspectives regarding this. Eighteen children participated in a mixed methods study (online surveys, telephone interviews). Descriptive statistics were calculated for child demographic and psychosocial factors. Thematic analysis was used to code and analyze the interviews. Most children reported having cooking experience (83%) and cooking with family (94%) and exhibited high cooking self-efficacy (21.8 ± 2.9) and positive cooking attitudes (25.7 ± 4.4). Children reported helping with meal preparation (50%) and grocery shopping (41%) sometimes. The qualitative data further supported the results obtained from the children's psychosocial factors. Most children noted the importance of learning to cook with an emphasis on life skills. Children also shared their level of involvement in cooking and grocery shopping. Most children reported using technology when cooking to find demonstration videos and recipes. These findings highlight that minority children participate in meal preparation and grocery shopping. Their perspectives are important for the development of nutrition education programs to achieve equitable dietary outcomes in minority families living in under-resourced communities.

Involvement of children in hands-on meal preparation and the associated nutrition outcomes: A scoping review

BACKGROUND

Emerging research has explored hands-on meal preparation as a strategy to improve children's nutrition-related outcomes. This scoping review was conducted to describe the extent of studies on children's involvement in hands-on meal preparation and the related psychosocial outcomes, actual nutrition behaviour/food consumption and weight status.

METHODS

Scoping review methodology was used to select relevant studies, as well as extract and collate the data. Four databases (PubMed, Google Scholar, Science Direct and Cochrane Database of Systematic Reviews) were searched from the earliest available time up to December 2020. Observational studies, experimental studies and reviews that were conducted among children aged 5-12 years old and published from 2010 to 2020 were retrieved. Studies extracted involved children in hands-on healthy meal preparation activities and explored the associated nutrition outcomes.

RESULTS

In total, 28 studies (5 observational studies, 21 experimental studies, 2 reviews) were included in the final review. Studies conducted demonstrated improvement in children's psychosocial outcomes and actual nutrition behaviour/food consumption after participating in hands-on meal preparation activities, despite differences in methodology, programme content and settings (countries/cultural origins). Limited studies assessed children's nutrients intake and weight status.

CONCLUSIONS

The current review suggests that hands-on meal preparation comprises approach for instilling positive perceptions towards nutrition/healthy foods, potentially improving children's diet. Future studies should include the assessment of nutrient intake and weight status. The long-term sustainability of these nutrition outcomes should be explored.

Parent-child cooking meal together may relate to parental concerns about the diets of their toddlers and preschoolers: a cross-sectional analysis in Japan

BACKGROUND

Parents often have concerns about the food habits of their young children. Cooking is a frequent behavior related to dietary activities at home. We hypothesized that "a parent cooking meals together with young children might alleviate dietary concerns." The aim of this study was to identify the relationship between parental cooking practices (e.g., cooking meals together with the child) and diet-related concerns.

METHODS

Data were extracted from the "National nutrition survey on preschool children" conducted among nation-wide households with toddlers and preschoolers in 2015 by the Ministry of Health, Labour and Welfare of Japan. Parents were classified into two groups comprising those who cooked meals together with their children and those who did not. The following variables were compared: taking too much time to eat (slow eaters), "picky" eating (eating only certain foods), inconsistent food intake (eating too much or too little), playing with food/utensils while eating, preferring sweetened beverages and snacks over meals, eating too fast to chew well, not swallowing food, disinterested in eating, and spitting out food. The associations between parent-child cooking meals together and the concerns pertaining to the child's dietary habits and food intake were analyzed and compared between the two groups.

RESULTS

The concerns of "picky eating" and "playing with food/utensils while eating" were lower, while "eating too much" was higher in the parent-cooking together group. The intake frequency of fish, soybeans/soy products, vegetables, and milk among children were higher in the "cooking together" group than among those in the "not cooking together" group. Children in the "cooking together" group consumed a significantly greater variety of foods than those in the "not cooking together" group.

CONCLUSIONS

Cooking a meal together with a child may be related to the parent's lower concerns about the dietary habits of the child, including "picky eating" and "playing with food/utensils while eating," but may also be related to the higher concerns of "eating too much."

Cooking together: The IKEA effect on family vegetable intake

OBJECTIVE

Based on the idea of the 'IKEA effect', assuming that individuals like self-created objects more than objects created by someone else, this study hypothesizes that parents' involvement of their children in meal planning and preparation is positively related to vegetable intake, mediated via liking vegetables.

DESIGN

Longitudinal observational study with two time points (10-month interval).

METHOD

Nine hundred and twenty-four parent-child dyads filled out questionnaires measuring involvement, vegetable liking, vegetable intake, and further environmental and food-related determinants of vegetable intake. On average, parents were M = 36.10 (SD = 5.43) and children (54.3% girls) M = 8.24 (SD = 1.44; range 6-11) years old. Hypotheses were tested with path analyses, accounting for intra-dyadic associations among respective constructs (e.g., parents' and children's liking vegetables).

RESULTS

Two direct effects were found: (1) parents' involvement of their children in cooking activities impacted children's liking of vegetables and vegetable intake, and (2) liking vegetables impacted vegetable intake. The effect of involvement on vegetable intake was mediated via liking vegetables, but only for children and not for parents.

CONCLUSIONS

The findings emphasize the importance of parents' encouragement for involving children in the preparation of healthy meals, as this improves liking of vegetables and, thereby, increases their vegetable intake. Statement of contribution What is already known on this subject? Processes behind the effectiveness of shared cooking activities to increase vegetable intake are unclear. Previous research suggests the IKEA effect as an explanation. It assumes a higher consumption of self-created products due to a higher liking compared to third-party products. What does this study add? First test of the IKEA effect for joint cooking activities under consideration of spillover effects in families. Affirmation of the IKEA effect was found for children, not for parents. Interventions should focus on the involvement of children in cooking activities to improve vegetable intake.

Helping With Meal Preparation and Children’s Dietary Intake: A Literature Review

Most children and adolescents do not meet dietary recommendations that may result in poor diets contributing to obesity. This systematic literature review was conducted to examine associations between helping with meal preparation at home and dietary quality, intake of specific foods, and/or dietary-related perceptions among youth. A search of databases using key terms was conducted for studies meeting criteria. This literature review included 15 studies using a cross-sectional descriptive design, with two studies also including a longitudinal design. Data were self-reported (or parent-reported) using various surveys and/or interviews. Study findings supported positive associations between youth involvement in home meal preparation and improvement in overall dietary quality, increased consumption of fruits and vegetables, greater preference for vegetables, and higher self-efficacy for cooking and choosing healthy foods. Further research is needed to develop efficacious meal preparation interventions involving parents and their children to promote this mealtime behavior with many potential health benefits.
