摘要
摘要背景:儿童健康状况最重要的威胁之一是超重和肥胖及其相关原因，如屏幕时间的流行。儿童超重和肥胖的流行与成年后的健康风险后果有关。目的:本研究的目的是评估超重和肥胖学生的屏幕时间和身体活动的患病率。患者和方法:在这个横断面描述性研究中，我们从Qazvin所有地区随机选择302名相对体重指数(rbmi)高于85百分位的学生。使用两种不同的技术(自我报告和父母报告)评估他们的屏幕时间和身体活动的流行程度。采用Pearson相关检验和回归分析检验RBMI、屏幕时间和体力活动之间的关系。结果:超重者(ST-SRT: 1.93±0.24 vs. 1.26±0.44,ST-PRT: 3.4±0.22 vs. 2.1±0.15)和肥胖者(ST-SRT: 1.88±0.31 vs. 1.37±0.49,ST-PRT: 3.2±0.32 vs. 2.3±0.34)的平均屏幕时间均多于女孩，但超重者的总屏幕时间少于肥胖者(P < 0.05)。单尾检验的Pearson相关性表明，屏幕时间与RBMI有显著相关。此外，屏幕时间和身体活动测量两种技术之间存在显著关联。屏幕时间与RBMI的回归模型显著(F = 45, P = 0.000, r2 = 0.42)，屏幕时间解释了RBMI约16%的方差(B = 0.021, SEB = 0.004， β = 0.325)。结论:我们的研究确定了屏幕时间、身体活动和RBMI之间的联系。屏幕时间是儿童RBMI的重要预测指标。卫生工作者必须减少儿童的屏幕时间，以防止超重和肥胖的流行。关键词:体力活动，久坐行为，超重，肥胖
Screen Time and Physical Activity in Overweight and Obese Students
Abstract Background: One of the most important threats for children’s health status is being overweight and obesity, and related causes such as
screen time prevalence. Prevalence of being overweight and obesity in children is associated with health risk consequences in adulthood. Objectives: The purpose of this study was to assess the prevalence of screen time and physical activity in overweight and obese students. Patients and Methods: In this cross sectional descriptive study we randomly selected 302 students, from all districts of Qazvin, who’s relative body mass index (RBMIs) were above the 85th percentile. Their screen time and physical activity prevalence were assessed with two separate techniques (self-report and parent-report). Pearson correlation test and regression analysis were done to examine the association between RBMI, screen time and physical activity. Results: Mean screen time in boys was more than girls, in both overweight screen time- self report technique (ST-SRT: 1.93 ± 0.24 vs. 1.26 ± 0.44, ST-PRT: 3.4 ± 0.22 vs. 2.1 ± 0.15) and obese subjects (ST-SRT: 1.88 ± 0.31 vs. 1.37 ± 0.49, ST-PRT: 3.2 ± 0.32 vs. 2.3 ± 0.34) yet overweight subjects had less total screen time than obese individuals (P < 0.05). Pearson correlations with one-tailed test indicated that screen time had a significant association with RBMI. In addition, there was a significant association between the two techniques of screen time and physical activity measurements. The model of regression for screen time and RBMI was significant (F = 45, P = 0.000, R

= 0.42) and screen time explained about 16% of variance in RBMI (B = 0.021, SEB = 0.004, β = 0.325). Conclusions: Our research determined an association between screen time, physical activity and RBMI. Screen time was a prominent predictor of RBMI in children. It is important for health workers to decrease screen time of children to prevent the prevalence of being overweight and obesity.
