摘要
目的了解广州市6~13岁学龄儿童代谢综合征(metabolic syndrome, MS)的流行现状,并分析视屏时间(screen time, ST)与MS的关系,为MS的防治提供科学依据。方法采用分层整群随机抽样方法,于2017年在广州市5个区随机抽取5所普通小学,共4 523名6~13岁学龄儿童参与调查。采用体格检查、问卷调查等方法,收集儿童ST及MS各指标情况,分析比较不同ST分组对MS指标的影响。结果广州市6~13岁学龄儿童MS检出率为2.4%,男生高于女生(3.0%,1.7%)(χ~2=7.12,P=0.01),且在不同年龄分组中检出率也不同(χ~2=25.08,P<0.01)。高水平ST组儿童占9.0%,高水平ST组儿童中心性肥胖、高三酰甘油和MS的检出率均高于低水平ST组(χ~2值分别为8.73,5.46,9.11,P值均<0.05)。Logistic回归分析结果显示,控制混杂因素后,与低水平ST组相比,高水平ST组儿童发生中心性肥胖和代谢综合征的OR值(OR值95%CI)分别为1.43(1.04~1.96)和1.94(1.11~3.40)。结论儿童视屏时间过长与罹患代谢综合征风险增加相关,积极有效的早期干预可预防儿童代谢综合征。
Objective To investigate the prevalence of metabolic syndrome(MS) and to explore the relationship of MS with screen time(ST) among children aged 6-13 years in Guangzhou, China. Methods A total of 4 523 children aged 6-13 from 5 primary schools in Guangzhou were selected using stratified random cluster sampling method. Questionnaire was used to assess children’s basic demographic characteristics and ST. Children’s height, weight, waist circumference and blood pressure were measured objectively, and their blood glucose, triglyceride and high-density lipoprotein-cholesterol were tested. Chi-square test was performed to compare the prevalence of MS in children among different ST levels. Logistic regression model was used to explore the association between ST and MS. Results The prevalence of MS in children was 2.4%, and that among boys(3.0%) was higher than in girls(1.7%, P=0.01). children were classified into three groups according to duration of ST: low ST(less than 1 h), moderate ST(1-2 h), high ST(higher than 2 h, 9.0% of total participants). Prevalence of central obesity, triacylglycerol and MS in high ST group was significantly higher than children with low ST(P<0.05). Children with high level of ST showed higher risks of central obesity(OR=1.43, 95%CI=1.04-1.96) and MS(OR=1.94, 95%CI=1.11-3.40) compared with low-level ST group. Conclusion Higher level of screen time associates with an increased risk of MS in children, which suggest the importance of effective early intervention.
