This study aimed to evaluate snack food-group composition by weight status among United States adolescents.
Cross-sectional analysis of adolescent food-group-component intake from snacking occasions using two 24-hour dietary recalls from the 2007 through 2018 National Health and Nutrition Examination Survey (NHANES; n = 5264; 12-19 years) was conducted. ANCOVA models evaluated food intakes by BMI percentile (BMI%; normal weight [NW]: <85th BMI%; overweight [OW]: 85th-95th BMI%; and obesity [OB]: ≥95th BMI%), adjusting for energy misreporting and key covariates.
Adolescents with OB consumed greater total daily energy from snacks (mean [SE]: NW = 424 [10] kcal; OW = 527 [16] kcal; OB = 603 [22] kcal; p < 0.001) than adolescents with OW and NW. Adolescents with OW or OB consumed higher amounts of refined grains, dairy, protein, oil, solid fat, and added sugar from snacks than adolescents with NW (p < 0.05-0.001).
Adolescents with OW or OB consume more calories and higher levels of overconsumed dietary components, i.e., added sugar, solid fats, and refined grains, from snacks than adolescents with NW. Age-specific snacking recommendations to inform dietary guidance are needed to prevent excess intake of overconsumed nutrients and calories.
本研究旨在评估美国青少年的体重状况对零食食品组构成的影响。
利用 2007 年至 2018 年全国健康和营养调查(NHANES)中两次 24 小时膳食回忆的数据,对青少年零食食品组成分的摄入量进行横断面分析(n=5264;12-19 岁)。采用协方差分析模型,根据 BMI 百分位(BMI%;正常体重[NW]:<85th BMI%;超重[OW]:85th-95th BMI%;肥胖[OB]:≥95th BMI%)评估食物摄入量,同时调整能量报告错误和关键协变量。
与 NW 组相比,OB 组青少年从零食中摄入的总日能量更多(均值[SE]:NW 组为 424[10]千卡;OW 组为 527[16]千卡;OB 组为 603[22]千卡;p<0.001)。OW 或 OB 组青少年从零食中摄入的精制谷物、乳制品、蛋白质、油、固体脂肪和添加糖的量均高于 NW 组(p<0.05-0.001)。
OW 或 OB 组青少年从零食中摄入的卡路里和过度摄入的膳食成分(如添加糖、固体脂肪和精制谷物)比 NW 组青少年更多。需要制定针对特定年龄段的零食推荐量,以指导饮食,从而防止过度摄入过度消耗的营养物质和卡路里。
