Ecological Momentary Assessment of the Breakfast, Lunch, and Dinner Family Meal Environment in Racially/Ethnically Diverse and Immigrant Households.

OBJECTIVE: To describe meal characteristics across breakfast, lunch, and dinner family meals in racially/ethnically diverse and immigrant/refugee households via ecological momentary assessment; identify real-time meal characteristics associated with family meal frequency; and identify qualitative themes regarding parents' perspectives about meal characteristics and meal types that influence family meal frequency. DESIGN: Cross-sectional study. SETTING: In-home visits. PARTICIPANTS: Children aged 5-7 years (n = 150) and their families from diverse and low-income households. MAIN OUTCOME MEASURE(S): Mixed methods. ANALYSIS: Multiple linear regression and hybrid deductive and inductive content analysis. RESULTS: Quantitative results indicated several similar meal characteristics occurring across weekdays and weekend days and by meal type (eg, parent prepared the meal, food mostly homemade, meal eaten at table) and some significant negative associations (P < .05) between meal characteristics and family meal frequency (eg, fast food for family meals). Eight main qualitative themes with several subthemes supported and expanded the quantitative findings and added depth to interpretation of the findings. CONCLUSIONS AND IMPLICATIONS: Results identified specific meal characteristics both quantitatively and qualitatively that may inform the development of interventions to increase the frequency of family meals so that more families can benefit from the protective nature of family meals.

Examining unanswered questions about the home environment and childhood obesity disparities using an incremental, mixed-methods, longitudinal study design: The Family Matters study.

There are disparities in the prevalence of childhood obesity for children from low-income and minority households. Mixed-methods studies that examine home environments in an in-depth manner are needed to identify potential mechanisms driving childhood obesity disparities that have not been examined in prior research. The Family Matters study aims to identify risk and protective factors for childhood obesity in low-income and minority households through a two-phased incremental, mixed-methods, and longitudinal approach. Individual, dyadic (i.e., parent/child; siblings), and familial factors that are associated with, or moderate associations with childhood obesity will be examined. Phase I includes in-home observations of diverse families (n=150; 25 each of African American, American Indian, Hispanic/Latino, Hmong, Somali, and White families). In-home observations include: (1) an interactive observational family task; (2) ecological momentary assessment of parent stress, mood, and parenting practices; (3) child and parent accelerometry; (4) three 24-hour child dietary recalls; (5) home food inventory; (6) built environment audit; (7) anthropometry on all family members; (8) an online survey; and (9) a parent interview. Phase I data will be used for analyses and to inform development of a culturally appropriate survey for Phase II. The survey will be administered at two time points to diverse parents (n=1200) of children ages 5-9. The main aim of the current paper is to describe the Family Matters complex study design and protocol and to report Phase I feasibility data for participant recruitment and study completion. Results from this comprehensive study will inform the development of culturally-tailored interventions to reduce childhood obesity disparities.
