To identify clusters of risk behaviors among Brazilian adults, by sex, and to associate clusters with sociodemographic factors and self-perception of health.
We assessed 46,785 adults from the Brazilian National Health Survey. The risk behaviors were low consumption of fruits and vegetables-LFV (< 5 times/week), physical inactivity-PI (< 150 min/week), smoking (yes/no) and excessive consumption of alcohol-EA (5 doses for male, 4 doses for female). We used Venn diagram, cluster analysis and multinomial regression models.
We found 9 clusters. The cluster of four risk behaviors was more common in males (3.2% vs. 0.83%). Despite a greater potential for aggregation of behaviors in females (O/E = 2.48) than in males (O/E = 1.62), the women were less likely to have all risk behaviors jointly (OR 0.24, 95% CI 0.19; 0.31), and this was found for the other clusters. In general, Brazilian black/brown, younger, with low education level and who had a self-perception of bad health, were more likely to engage in clusters of risk behaviors.
The prevalence of Brazilian adults engaging in clusters of risk behaviors is high, mainly among males, those who reported a bad health and with low socioeconomic status.
根据性别确定巴西成年人的风险行为群集，并将这些群集与社会人口学因素和自我健康感知相关联。
我们评估了来自巴西国家健康调查的 46785 名成年人。风险行为包括低水果和蔬菜摄入量（每周 < 5 次）、缺乏身体活动（每周 < 150 分钟）、吸烟（是/否）和过量饮酒（男性 5 剂量，女性 4 剂量）。我们使用了 Venn 图、聚类分析和多项回归模型。
我们发现了 9 个群集。四种风险行为的群集在男性中更为常见（3.2%比 0.83%）。尽管女性行为聚集的可能性更大（O/E=2.48 比男性 O/E=1.62），但女性更不可能同时存在所有风险行为（OR 0.24，95%CI 0.19; 0.31），其他群集也存在这种情况。总体而言，巴西的黑/棕色人种、年轻、教育程度低和自我健康感知差的人群更有可能参与风险行为群集。
巴西成年人参与风险行为群集的患病率很高，主要集中在男性、健康状况不佳和社会经济地位较低的人群中。
