This study examined the association between simultaneity of four health-risk behaviours, namely, low levels of moderate-to-vigorous physical activity (insufficient MVPA: <420 min/week), tobacco use, alcohol consumption, and excessive television (TV)-(>2 h/d of TV viewing) and self-rated health (SRH) in Brazilian adolescents.
We used data of 100,551 adolescents from the National School Health Survey, a national cross-sectional study carried out in 2015. Association between simultaneity of health risk behaviours (i.e. the ratio between observed and expected prevalence rates) and SRH was examined using logistic regression models.
The majority of the participants were female (51.9%) and 14 years of age (50.6%), and 26% of the participants' SRH ranged from 'average' to 'extremely poor'. Those who engaged in the following combinations of health-risk behaviours had higher odds of worse SRH than their healthier counterparts: insufficient MVPA and tobacco use (odds ratio-OR: 2.0, 95% confidence interval [CI]: 1.4 to 3.0); insufficient MVPA and alcohol consumption (OR: 1.6, 95%CI: 1.3 to 1.9); insufficient MVPA and >2 h/day of TV viewing (OR: 1.3, 95%CI: 1.1 to 1.6); insufficient MVPA, tobacco use and alcohol consumption (OR: 2.1, 95%CI: 1.7, to 2.7); and insufficient MVPA, alcohol consumption and >2 h/day of TV viewing (OR: 1.6, 95%CI: 1.4 to 2.0).
Insufficient MVPA, alcohol consumption, and other health-risk behaviours were associated with worse SRH in Brazilian adolescents.
本研究旨在探讨四种健康风险行为（即中高强度体力活动水平低[每周不足 420 分钟]、吸烟、饮酒和过度看电视[每天观看电视超过 2 小时]）同时发生与巴西青少年自我报告健康（SRH）之间的关系。
我们使用了 2015 年进行的全国性横断面研究——全国学校卫生调查的数据，该研究共纳入了 100551 名青少年。使用逻辑回归模型检验健康风险行为同时发生的情况（即观察到的流行率与预期流行率的比值）与 SRH 之间的关系。
大多数参与者为女性（51.9%）和 14 岁（50.6%），26%的参与者的 SRH 处于“一般”到“极差”的水平。与健康状况较好的参与者相比，以下健康风险行为组合的青少年更有可能出现较差的 SRH：中高强度体力活动不足且吸烟（比值比[OR]：2.0，95%置信区间[CI]：1.4 至 3.0）；中高强度体力活动不足且饮酒（OR：1.6，95%CI：1.3 至 1.9）；中高强度体力活动不足且每天观看电视超过 2 小时（OR：1.3，95%CI：1.1 至 1.6）；中高强度体力活动不足、吸烟和饮酒（OR：2.1，95%CI：1.7 至 2.7）；中高强度体力活动不足、饮酒和每天观看电视超过 2 小时（OR：1.6，95%CI：1.4 至 2.0）。
在巴西青少年中，中高强度体力活动不足、饮酒和其他健康风险行为与较差的 SRH 相关。
