This paper concerns a cross-sectional population-based study conducted with adults living in the city of Pelotas, Rio Grande do Sul State, Brazil. It aims to determine the prevalence of weight-loss practices and use of substances for weight-loss during the 12 months preceding the interview. The prevalence of weight-loss attempts was 26.6%. Although dietary control and regular physical exercise were the most commonly used strategies, the prevalence of the combined use of these methods was only 36% for individuals trying to lose weight. The prevalence of use of substances for weight-loss was 12.8% (48.4% of those who tried to lose weight). The use of dietary control and substances was more common among women, while men practiced physical exercise with greater frequency. Teas were the most frequently used substances for weight-loss. Multivariate analysis identified being female, excess weight and self-perception of excess weight as major associated factors for the use of substances for weight-loss. Finally, we found that, although weight-loss attempts are common, the majority of obese individuals do not make attempts to lose weight and only a minority follows the recommended practices.
本文是一项基于人群的横断面研究，对象为巴西南里奥格兰德州佩洛塔斯市的成年人。旨在确定在访谈前的 12 个月内，减肥实践和使用减肥物质的流行率。减肥尝试的流行率为 26.6%。尽管饮食控制和有规律的体育锻炼是最常用的策略，但对于试图减肥的人来说，这些方法联合使用的流行率仅为 36%。减肥物质的使用流行率为 12.8%（尝试减肥者中有 48.4%使用了减肥物质）。饮食控制和物质的使用在女性中更为常见，而男性则更频繁地进行体育锻炼。茶是最常被用于减肥的物质。多变量分析确定女性、超重和自我感知超重是使用减肥物质的主要相关因素。最后，我们发现，尽管减肥尝试很常见，但大多数肥胖者并不试图减肥，只有少数人遵循推荐的做法。
