Abstract

OBJECTIVE

Sedentary behaviour is associated with poorer mental health in adolescence but no studies have followed participants into mid-life. We investigated the association between after-school sedentary behaviours (screen time and homework) in adolescence with mental wellbeing in adulthood when participants were aged 42.

METHODS

Participants (n=2038, 59.2% female) were drawn from The 1970 British Cohort Study (BCS70). At age 16 respondents were asked separate questions about how long they spent in three types of screen based activities (TV, video films, computer games) and homework 'after school yesterday'. Mental well-being and psychological distress were assessed at the age 42 sweep in 2012 using the Warwick-Edinburgh Mental Well-being Scale (WEMWBS) and Malaise Inventory, respectively.

RESULTS

After adjustment for all covariates, participants reporting more than 3h of after school screen time as an adolescent had -1.74 (95% CI, -2.65, -0.83) points on the WEMWBS compared with adults reporting less than 1h screen time as an adolescent. Participants that reported high screen time both at age 16 (≥3h/d) and age 42 (≥3h/d TV viewing) demonstrated even lower scores (-2.91; -4.12, -1.69). Homework was unrelated to wellbeing after adjustment for covariates. The longitudinal association between adolescent screen time and adult psychological distress was attenuated to the null after adjustment for covariates.

CONCLUSIONS

Screen time in adolescence was inversely associated with mental wellbeing in adulthood.

摘要

目的

久坐行为与青少年较差的心理健康状况相关，但尚无研究追踪参与者至中年。我们调查了青少年时期课后久坐行为（屏幕使用时间和家庭作业）与42岁成年时心理健康之间的关联。

方法

参与者（n = 2038，59.2%为女性）来自1970年英国队列研究（BCS70）。在16岁时，受访者被分别问及他们在三种基于屏幕的活动（电视、视频电影、电脑游戏）以及“昨天放学后”的家庭作业上花费了多长时间。2012年在42岁随访时，分别使用沃里克 - 爱丁堡心理健康量表（WEMWBS）和不适量表评估心理健康和心理困扰情况。

结果

在对所有协变量进行调整后，与青少年时期屏幕使用时间少于1小时的成年人相比，报告青少年时期课后屏幕使用时间超过3小时的参与者在WEMWBS上的得分低1.74（95%可信区间，-2.65，-0.83）分。在16岁（≥3小时/天）和42岁（≥3小时/天看电视）时均报告高屏幕使用时间的参与者得分更低（-2.91；-4.12，-1.69）。在对协变量进行调整后，家庭作业与幸福感无关。在对协变量进行调整后，青少年屏幕使用时间与成人心理困扰之间的纵向关联减弱至无统计学意义。
