          Abstract

          Objective To understand the relationship between screen time and dietary behaviors among urban middle school students in Guangzhou, and to provide scientific evidence for improving students’ health.

          Methods Based on the regular medical examinations for elementary and middle school students in Guangzhou, a total of 12 357 middle school students (grade 7 and grade 10) were investigated by using a cross-sectional study. The physical indicators and daily routine were collected by physical examination and questionnaire survey. Multiple Logistic regression analysis was used to explore the association between screen time and dietary behaviors among students.

          Results The proportion of excessive screen time was 18.80% (2 323). There was no significant difference between boys (18.52%, 1 165/6 292) and girls (19.09%, 1 158/6 065) (χ 2 = 0.67, P>0.05). Logistic regression results showed that excessive screen time was negatively associated with consumption of vegetables and fruits, with the aORs of 0.50 (95% CI = 0.42-0.58) and 0.64 (95% CI = 0.58-0.70) respectively, and positively associated with consumption of fried food ( OR =1.90, 95%CI =1.70-2.09), western fast food ( OR = 1.90, 95% CI =1.65-2.19), sweets ( OR = 1.36, 95% CI = 1.25-1.49) and sugar-sweetened beverage ( OR =1.70, 95% CI = 1.57-1.84).

          Conclusion Excessive screen time was associated with unhealthy dietary behaviors among middle school students in Guangzhou. Intervention should be tailored to screen time as well as dietary behaviors.

          Abstract

          【摘要】目的探讨广州市城区中学生视屏时间与饮食行为的关系,为实施中学生健康促进提供科学依据。 方法 采用横断面研究,以广州市城区12 357名初一、高一新生为研究对象,通过问卷调查和体格检查收集学生体质状况、生活 作息等资料。采用多因素Logistic回归模型对学生的视屏时间与饮食行为进行关联分析。 结果中学生视屏时间过长的 检出率为18.80%(2 323名),其中男生为18.52%(1 165/6 292),女生为19.09% (1 158/6 065),差异无统计学意义(χ 2 = 0.67,_P>0.05)。Logistic 回归分析显示,视屏时间过长与蔬菜( OR = 0.50,95%CI = 0.42〜0.58)、水果( OR = 0.64,95%CI =0.58 〜0.70)的摄人频率存在负关联;与油炸类食品( OR =1.90,95%CI = 1.70〜2.09)、西式快餐( OR =1.90,95%CI =1.65〜2.19)、 甜食( OR =1.36,95%CI =1.25〜1.49)和含糖饮料( OR =1.70,95%CI =1.57〜1.84)的摄人频率存在正关联( P值均<0.01)。 结论广州市城区中学 , 好的健康饮食行为。
