To understand the influence of eating frequency and snack quality on body weight of preschool children ages 3 up to 5 years participating in the Broward County Special Supplementation Nutrition Program for Women, Infants, and Children (WIC). Cross-sectional data were collected from all 7 Broward County Health Department WIC clinics over 4 months via a researcher-administered questionnaire. Additional data were extracted from the WIC data system. Centers for Disease Control and Prevention’s BMI-for-age percentiles were used to classify children into weight categories that were combined into under/normal weight and overweight/obese. Snacks were categorized into nutrient-based food groups and assigned a quality score. A total of 197 participants [90 boys (45.7%) and 107 girls (54.3%)] were included. From those, 3.6% were underweight, 64.4% normal weight, 16.8% overweight and 15.2% were obese. Most children consumed 3 meals (97.5%) and between 2 (33%) to 3 (37.1%) snacks on average per day. Mean number of snacks on the weekend was significantly higher than on weekdays (2.78 ± 1.20 vs. 2.67 ± 1.08, P = 0.001). We found a tendency for a lower prevalence of overweight/obesity as the number of eating events increased, although it was not significant. The most frequently consumed snacks were milk, 100% fruit juice, and fresh fruits, consumed daily by more than 75% of the children, irrespective of weight category. There was an overall higher consumption of more nutritious snacks when compared to nutrient-poor snacks (66% vs. 33.5%), with under/normal weight children consuming nutritious snacks more frequently than overweight/obese children (P = 0.09). Most children included in this study engaged in frequent eating events with a higher intake of the more nutritious snacks, which were both associated with a lower prevalence of overweight/obesity. Our findings suggest that in this age range, participation in the WIC program may foster positive eating behaviors. A.C. was supported by a NIH/NIGMS R25 grant.
