Family dinner and adolescent overweight.

Area of Science:

• Pediatric health
• Nutrition science
• Obesity research

Background:

• Childhood obesity is a significant public health concern.
• Family meals are proposed to influence children's health behaviors and outcomes.
• Understanding the relationship between family dinner frequency and weight status is crucial for developing effective interventions.

Purpose of the Study:

• To investigate cross-sectional and longitudinal associations between family dinner frequency and overweight status in children aged 9-14.
• To analyze how often children eat family dinner and its correlation with their Body Mass Index (BMI).

Main Methods:

• A cohort of 14,431 children (7784 girls, 6647 boys) aged 9-14 participated in the Growing Up Today Study.
• Data collected via annual mailed surveys from 1996 to 1999 included self-reported height, weight, and family dinner frequency.
• Overweight was defined as age- and sex-specific BMI >85th percentile; logistic regression models were used for analysis.

Main Results:

• At baseline, 44% of children ate family dinner every day, 40% on most days, and 16% on some days or never.
• Cross-sectional analysis showed an inverse association: children eating dinner most or every day had lower odds of being overweight (OR=0.85).
• Longitudinal analysis did not find a significant association between family dinner frequency and the 1-year incidence of becoming overweight.

Conclusions:

• Frequent family dinners were associated with lower overweight prevalence at the study's start.
• However, family dinner frequency did not predict the likelihood of children becoming overweight over the subsequent year.
• Further research is needed to understand the complex interplay between family dynamics and childhood weight management.
