What this study is about

Obesity continues to be a major public health concern, and children who are overweight by age 5 are at increased risk for future obesity, highlighting the importance of early efforts to promote healthy eating and growth. The goal of this project is to test a new family-based approach to early childhood obesity prevention, specifically using pre-filled, online grocery shopping carts to make it easier for parents to select healthy foods like fruits and vegetables. This study will be the first to test whether such default shopping carts can help promote the purchasing and consumption of healthier foods, as well as healthier diets and weight outcomes, among parents with obesity and their 2-to-5-year-old children, offering the potential for a meaningful impact on the health of young children and their families.

Full registry criteria

Inclusion Criteria: * The participating adult must be \>18 years old * Participating adult is English speaking * Participating adult has a self-reported body mass index \>30 * Participating adult has a 2-to-5-year-old child * The participant also must report online grocery shopping from study stores (Aldi, Tops, Wegman's, and/or Walmart) at least 2 times per month * Willing to purchase fresh foods online (e.g., fruits, vegetables, meat if meat is consumed), vs. using online shopping solely for shelf-stable pantry staples. * Participants also must be a primary caregiver of the enrolled child * Do greater than or equal to 75% of their grocery shopping from study stores and at least 50% of the grocery shopping for the family. Exclusion Criteria: * Families in which the child is underweight (BMI-for-age percentile \<5) will be excluded * There must not be family dietary restrictions that preclude being able to use at least some recipes in the study's recipe bank.

Treatments and study arms

Recipes

Behavioral

Packet of healthy recipes provided each week of a 6-month intervention, with nutrition education and healthy eating tips included.

Pre-filled carts

Behavioral

Participants' online grocery carts are pre-filled with the ingredients from the main meal recipes featured in provided recipe packets that week. Participants can change these carts as they like.

Primary outcomes

Nutritional quality of household grocery purchases6 months

Nutritional quality of household grocery purchases will be coded in accordance with the Healthy Eating Index and will include all groceries purchased that time point (online or in-person, etc.). Grocery purchases are scored in 13 categories from the Healthy Eating Index, with quintiles used to operationalize lower versus higher purchasing of these categories (ex. fruits, vegetables, whole grains), with a resulting possible nutritional quality range of 13-65. Two weeks of data collection occur per time point, and values are averaged to represent the average weekly nutritional quality of grocery purchases at that time point. Analyses will compare the nutritional quality of grocery purchases between groups at the primary outcome time point of 6 months, immediately after the conclusion of the intervention, in the context of marginal models adjusting for baseline nutritional quality, stratif…

Energy content of household grocery purchases6 months

Energy content will be operationalized across all household grocery purchases in kcal. Two weeks of data collection occur per time point, and values are averaged to represent the average weekly energy content of grocery purchases at that time point. Analyses will compare the energy content of grocery purchases between groups at the primary outcome time point of 6 months, immediately after the conclusion of the intervention, in the context of marginal models adjusting for baseline energy content, stratification factors, and household size.

Fruits purchased6 months

The number of different types of fruits purchased will be operationalized across all household grocery purchases. Two weeks of data collection occur per time point, and values are averaged to represent average number of fruits purchased. Analyses will compare fruits purchased between groups at the primary outcome time point of 6 months, immediately after the conclusion of the intervention, adjusting for baseline fruit purchasing, stratification factors, and household size.

Vegetables purchased6 months

The number of different types of vegetables purchased will be operationalized across all household grocery purchases. Two weeks of data collection occur per time point, and values are averaged to represent average number of vegetables purchased. Analyses will compare vegetables purchased between groups at the primary outcome time point of 6 months, immediately after the conclusion of the intervention, adjusting for baseline vegetable purchasing, stratification factors, and household size.

High energy dense foods purchased6 months

The number of different types of high energy dense foods purchased will be operationalized across all household grocery purchases. Two weeks of data collection occur per time point, and values are averaged to represent average number of high energy dense foods purchased. Analyses will compare high energy dense foods purchased between groups at the primary outcome time point of 6 months, immediately after the conclusion of the intervention, adjusting for baseline high energy dense food purchasing, stratification factors, and household size. High energy dense foods are coded based on cut-offs from the Traffic Light Diet (e.g., sugar \>25% of calories/serving).
