Dietary patterns established during childhood and adolescence often persist into adulthood, and therefore have implications for the risk of developing chronic diseases, not only in the near term but also in the future (–3). Rising rates of overweight and obesity among children and adults in recent years (–5) have led researchers to evaluate associations between various eating patterns and weight status. One pattern that has received considerable attention is eating more frequently, particularly in the form of snacking (6). Although some studies have shown that eating patterns which include snacking may help people meet their nutrient needs, other studies indicate that snacking can lower the nutrient density (i.e., the amount of nutrients per calorie) of the total diet (–9). Data on the prevalence of snacking among adolescents and its association with body mass index (see page 3) and with food and nutrient intakes are presented in this report.
