Sedentary behavior may affect the types of food consumed in children and adolescents' daily diets. Previous published studies are limited to local surveys. This study aimed to explore the relationship between sedentary behavior and food intake among children and adolescents.
A stratified sampling technique was employed in the present cross-sectional study. Demographic characteristics, sedentary behavior, transportation modes, and food intake were investigated.
We found that children and adolescents who watched movies or TV programs online or on their smartphones on weekends and who chatted online on weekends, including on QQ (an instant messaging software service) and WeChat (an instant messaging software service), increased their intake of instant noodles and fried pasta (Spearman's rho = 0.468, 0.575, 0.465, and 0.323; < 0.05). Children and adolescents who chatted online on weekends, including on QQ and WeChat, increased their intake of tofu skin (Spearman's rho = 0.461; < 0.05), and those who browsed online on weekdays increased their intake of whole-fat liquid milk (Spearman's rho = 0.455; < 0.05). Children and adolescents who browsed and chatted online on weekends, including on QQ and WeChat, and who played computer or smartphone games, increased their intake of fried potato chips (French fries or other fried snacks) (Spearman's rho = 0.568, 0.270, and 0.412; < 0.05). With respect to modes of transportation used to travel to and from school, children and adolescents who took buses and subways increased their intake of rice, instant noodles, sweet potatoes, soybean milk, tofu skin, processed meat products (sausage, ham sausage, or lunch meat), fish, shrimp, vegetables, nuts, and sweet cookies (buns, cakes, Dim sum, and moon cakes) (Spearman's rho = 0.394, 0.536, 0.630, 0.408, 0.485, 0.441,0.410, 0.424, 0.444, 0.541, and 0.366; < 0.05).
Sedentary behavior affects the types of food consumed in children and adolescents' daily diets. Children and adolescents who browsed online on weekdays increased their intake of whole-fat liquid milk, but also increased their intake of foods with high fat, high salt, and low nutrient density. Children and adolescents taking buses and subways increased their intake of low-nutrition quality products. Public awareness efforts should focus on reducing the consumption of low-nutrition quality products and nutritional education.
久坐行为可能会影响儿童和青少年日常饮食中所摄入的食物类型。之前发表的研究仅限于局部调查。本研究旨在探讨儿童和青少年久坐行为与食物摄入之间的关系。
本横断面研究采用分层抽样技术。调查了人口统计学特征、久坐行为、交通方式和食物摄入情况。
我们发现，周末在智能手机或在线上看电影或电视节目的儿童和青少年，以及周末在线聊天（包括 QQ 和微信）的儿童和青少年，会增加方便面和炒面（意大利面）的摄入量（Spearman's rho = 0.468、0.575、0.465 和 0.323；<0.05）。周末在线聊天（包括 QQ 和微信）的儿童和青少年会增加豆腐皮的摄入量（Spearman's rho = 0.461；<0.05），而工作日在线浏览的儿童和青少年会增加全脂液态奶的摄入量（Spearman's rho = 0.455；<0.05）。周末在线浏览、在线聊天（包括 QQ 和微信）以及玩电脑或智能手机游戏的儿童和青少年会增加薯条（炸薯条或其他油炸零食）的摄入量（Spearman's rho = 0.568、0.270 和 0.412；<0.05）。就上下学的交通方式而言，乘坐公共汽车和地铁的儿童和青少年会增加米饭、方便面、红薯、豆浆、豆腐皮、加工肉制品（香肠、火腿或午餐肉）、鱼类、虾类、蔬菜、坚果和甜饼干（馒头、蛋糕、点心和月饼）的摄入量（Spearman's rho = 0.394、0.536、0.630、0.408、0.485、0.441、0.410、0.424、0.444、0.541 和 0.366；<0.05）。
久坐行为会影响儿童和青少年日常饮食中所摄入的食物类型。工作日在线浏览的儿童和青少年增加了全脂液态奶的摄入量，但也增加了高脂肪、高盐和低营养密度食物的摄入量。乘坐公共汽车和地铁的儿童和青少年增加了低营养质量产品的摄入量。公众意识工作应侧重于减少低营养质量产品的消费和营养教育。
