Survey Design and Sample
This study uses data on subjects aged 2 to 18 years from 3 nationally representative surveys of the US population. Of these 21,236 individuals, 12,231 participated in the 1977-78 Nationwide Food Consumption Survey (NFCS77), 4008 participated in the 1989-91 Continuing Survey of Food Intake by Individuals, and 4997 participated in the 1994-96 CSFII96. The United States Department of Agriculture surveys from 1977 and 1989 contain stratified area probability samples of noninstitutionalized US
Who Is Snacking?
The prevalence of snackers among children increased over all ages from 77% to 91% during the years covered. The changes in the percent of snackers, overall and within age groups, were minimal or nonexistent between 1977 and 1989; most of the increase occurred between 1989 and 1996 (Fig 1).

Discussion
This study presents a picture of an important increase in the prevalence and dietary contribution of snacking in the diets of US children. Currently, snacking represents approximately a fourth of the energy and a fifth of many other nutrients, similar to any other meal occasion. The increase in nutrient contribution is primarily caused by an increase in the frequency of snacking and not the size of each snack. Moreover, energy density is much higher for snacks than the non-snacking component of

Many studies report that obesity is mainly caused by eating lots of small snacks (Jahns et al., 2001) and fast food (Bowman et al., 2004). Obesity is related to several chronic diseases including stroke, diabetes, heart, and liver diseases (Field et al., 2001; American College of Gastroenterology, 2008).
