The prevalence of overweight among Swedish young adults has nearly doubled since the 1980s. The weight increase has been paralleled by the increased use of computers at work, at school, and at leisure time. The aim was to examine leisure time computer use for gaming, and for emailing/chatting, in relation to overweight development in young adults.
A prospective cohort study with Swedish young adults (20-24 years at baseline) who responded to a questionnaire at baseline (n = 6735), and after 1 year (n = 3928) and 5 years (n = 2593). Exposure variables were average daily time spent on leisure time computer gaming and emailing/chatting. Logistic regression was performed for cross-sectional analyses with overweight (BMI ≥ 25) and obesity (BMI ≥ 30) as the outcomes, and for prospective analyses with new cases of overweight at the 1- and 5-year follow-ups. Change in BMI from baseline to 5 year-follow-up was analyzed with linear regression.
There were cross-sectional and prospective associations between computer gaming and overweight (BMI ≥ 25) in women, after adjusting for age, occupation, physical activity, sleep, social support, and total computer use. For the men, only cross-sectional associations could be seen. Spending more than 2 h daily for emailing and chatting was related cross-sectionally to overweight in the women. No clear prospective associations were found for emailing/chatting and overweight development in either sex.
We have identified a new risk group for overweight development: young adult female computer gamers. Leisure time computer gaming was a prospective risk factor for overweight in women even after adjusting for demographic and lifestyle factors, but not in men. There were no clear prospective associations between computer use for emailing/chatting and overweight in either sex.
自20世纪80年代以来，瑞典年轻成年人中超重的患病率几乎翻了一番。体重增加的同时，工作、学校和休闲时间使用电脑的情况也在增加。目的是研究年轻人休闲时间使用电脑进行游戏、收发电子邮件/聊天与超重发展之间的关系。
一项针对瑞典年轻成年人（基线时年龄为20 - 24岁）的前瞻性队列研究，这些人在基线时（n = 6735）、1年后（n = 3928）和5年后（n = 2593）对问卷进行了回复。暴露变量是休闲时间用于电脑游戏和收发电子邮件/聊天的平均每日时间。进行逻辑回归以进行横断面分析，将超重（BMI≥25）和肥胖（BMI≥30）作为结果，以及进行前瞻性分析，以1年和5年随访时的超重新病例为对象。使用线性回归分析从基线到5年随访时BMI的变化。
在调整年龄、职业、身体活动、睡眠、社会支持和总电脑使用时间后，女性中电脑游戏与超重（BMI≥25）之间存在横断面和前瞻性关联。对于男性，只能看到横断面关联。女性中，每天花费超过2小时收发电子邮件和聊天与超重存在横断面关联。在两性中，未发现收发电子邮件/聊天与超重发展之间有明确的前瞻性关联。
我们确定了一个超重发展的新风险群体：年轻成年女性电脑游戏玩家。即使在调整人口统计学和生活方式因素后，休闲时间电脑游戏仍是女性超重的一个前瞻性风险因素，但男性并非如此。两性中，用于收发电子邮件/聊天的电脑使用与超重之间均未发现明确的前瞻性关联。
