Abstract：
Childhood overweight/obesity is a serious problem that has not been adequately addressed. As a key factor affecting weight gain, the association between dietary intake with childhood overweight and obesity is still unclear. The objective of this study was to analyze the association between sociodemographic, lifestyle factors and dietary intake with overweight or obesity. We used data from a large cross-sectional National Health and Nutrition Examination Survey (NHANES). The U.S. children aged 6-15 years with both weight data and dietary data were included. For univariate analysis of sociodemographic data, t tests was performed for continuous variables and chi-square tests was performed for discrete variables. Dietary intakes were described by median and quartile, and differences in dietary intake between children with normal weight and children with overweight or obesity were compared by rank sum tests. A modern statistical shrinkage technique, LASSO regression was used to examine the association between dietary intake and childhood obesity. Our study confirms that Hispanic ethnicity, increasing age, passive exposure to smoking, higher protein intake, and higher caffeine intake were positively associated with child overweight or obesity. Additionally, non-Hispanic White race, higher physical activity levels, higher household income, and higher vitamin A intake were negatively associated with child overweight or obesity.
摘要：
儿童超重/肥胖是一个尚未得到充分解决的严重问题。作为影响体重增加的关键因素，膳食摄入与儿童超重和肥胖之间的关系尚不清楚.这项研究的目的是分析社会人口统计学，生活方式因素和饮食摄入超重或肥胖。我们使用了来自大型横断面国家健康和营养检查调查（NHANES）的数据。包括体重数据和饮食数据的6-15岁美国儿童。对于社会人口统计学数据的单变量分析，连续变量进行t检验，离散变量进行卡方检验。饮食摄入量由中位数和四分位数描述，通过秩和检验比较体重正常儿童和超重或肥胖儿童的饮食摄入量差异。一种现代统计收缩技术，LASSO回归用于检查饮食摄入与儿童肥胖之间的关系。我们的研究证实了西班牙裔种族，年龄越来越大,被动吸烟，更高的蛋白质摄入量，较高的咖啡因摄入量与儿童超重或肥胖呈正相关。此外,非西班牙裔白人种族,更高的身体活动水平，更高的家庭收入，较高的维生素A摄入量与儿童超重或肥胖呈负相关。
