OBJECTIVE
To investigate the prevalence and correlates of high screen time (ST) among students in Zhejiang, China.
DESIGN
Cross-sectional study.
SETTING
School-based adolescent health survey in Zhejiang Province, China.
PARTICIPANTS
23 543 students in grades 7-12 from 442 different schools.
OUTCOME
High ST.
RESULTS
The mean age of the students was 15.6 years and 49.7% of them were girls. The prevalence of high ST (screen viewing ≥2 hours per day) was 42.4% (95% CI 40.2% to 44.5%), higher in boys than in girls (45.4%(95% CI 42.8% to 48.0%) vs 39.1% (95% CI 36.6% to 41.7%)). No statistically significant difference was found between urban and rural areas (43.0% (95% CI 37.2% to 48.7%) vs 42.1% (95% CI 39.6% to 44.6%)). The prevalence of high ST among middle school, academic high school and vocational high school students was 35.3%, 30.0% and 73.5%, respectively. Multivariable logistic analysis showed that older age, attendance at vocational high school, non-intact family, poor academic performance, bad self-reported health status, loneliness and drinking carbonated beverages ≥3 times every day were positively associated with high ST. Attendance at academic high school, higher parental education and being physically active were negatively associated with high ST.
CONCLUSIONS
High ST was prevalent among students and associated with a cluster of sociodemographic and behavioural risk factors in Zhejiang, China.
目的
调查中国浙江学生中高屏幕时间（ST）的流行率及其相关因素。
设计
横断面研究。
地点
中国浙江省基于学校的青少年健康调查。
参与者
来自 442 所不同学校的 23543 名 7-12 年级学生。
结局
高 ST。
结果
学生的平均年龄为 15.6 岁，其中 49.7%为女生。高 ST（屏幕观看时间≥2 小时/天）的患病率为 42.4%（95%可信区间 40.2%至 44.5%），男生高于女生（45.4%（95%可信区间 42.8%至 48.0%）比 39.1%（95%可信区间 36.6%至 41.7%）。城乡之间无统计学差异（43.0%（95%可信区间 37.2%至 48.7%）比 42.1%（95%可信区间 39.6%至 44.6%））。初中生、中专生和职业高中生高 ST 的患病率分别为 35.3%、30.0%和 73.5%。多变量逻辑分析显示，年龄较大、上职业高中、非完整家庭、学业成绩差、自我报告健康状况差、孤独感和每天饮用碳酸饮料≥3 次与高 ST 呈正相关。上中专、父母受教育程度较高和身体活跃与高 ST 呈负相关。
结论
高 ST 在浙江学生中普遍存在，并与一系列社会人口和行为风险因素相关。
