To describe the epidemiology of small screen recreation (SSR) that is: television, computer, video, and DVD use among school students aged 11-15 years in New South Wales, Australia.
Cross-sectional representative population survey (n=2750) of 45 primary and 48 secondary schools in rural and urban areas. Self-reported time spent in SSR was categorised according to national guidelines into less than 2 h per day (low users) or 2 or more hours per day (high users).
Of primary and secondary school students, 53% and 72%, respectively, were high users of SSR. Boys spent significantly more time in SSR and were more likely to be high users of SSR compared with girls. For primary students, rural boys had a higher prevalence of high SSR use than urban boys (odds ratio (OR) 1.9, 95% confidence interval (CI) 1.0-3.5), while overweight girls had a higher prevalence than healthy-weight girls (OR 1.8, 95% CI 1.2-2.8). For secondary students, rural boys had a lower prevalence of high SSR use than urban boys (OR 0.5, 95% CI 0.3-0.6), and girls from high SES backgrounds had a lower prevalence than girls from low socio-economic status backgrounds (OR 0.6, 95% CI 0.3-1.0).
The majority of school students in New South Wales exceed the national guidelines for SSR. Reducing the time spent in SSR among young people is one potential approach to increasing energy expenditure and reducing adiposity or maintaining a healthy weight. First steps for intervention strategies among school-age children to reduce SSR could include teaching awareness skills and self-monitoring techniques.
描述澳大利亚新南威尔士州11至15岁在校学生的小屏幕娱乐活动(SSR)的流行病学情况,即电视、电脑、视频和DVD使用情况。
对农村和城市地区45所小学和48所中学进行横断面代表性人口调查(n = 2750)。根据国家指南,将自我报告的SSR活动时间分为每天少于2小时(低使用者)或每天2小时及以上(高使用者)。
小学生和中学生中分别有53%和72%是SSR的高使用者。与女孩相比,男孩在SSR上花费的时间显著更多,且更有可能是SSR的高使用者。对于小学生,农村男孩的SSR高使用率高于城市男孩(优势比(OR)为1.9,95%置信区间(CI)为1.0 - 3.5),而超重女孩的患病率高于健康体重女孩(OR为1.8,95% CI为1.2 - 2.8)。对于中学生,农村男孩的SSR高使用率低于城市男孩(OR为0.5,95% CI为0.3 - 0.6),来自高社会经济地位背景的女孩患病率低于来自低社会经济地位背景的女孩(OR为0.6,95% CI为0.3 - 1.0)。
新南威尔士州的大多数在校学生超过了SSR的国家指南标准。减少年轻人在SSR上花费的时间是增加能量消耗、减少肥胖或维持健康体重的一种潜在方法。针对学龄儿童减少SSR的干预策略的第一步可以包括教授认知技能和自我监测技巧。
