To estimate the prevalence of overweight and obesity and factors associated.
The study analyzed data referring to individuals aged 18 years or older interviewed through the system Vigilância de Fatores de Risco e Proteção para Doenças Crônicas por Inquérito Telefônico (VIGITEL--Telephone-based surveillance of risk and protective factors for chronic diseases), carried out in the Brazilian capitals and Federal District in 2006. For 49,395 individuals, the body mass index (BMI) was used to identify overweight (BMI > or = 25 kg/m2) and obesity (BMI > or = 30 kg/m2). Prevalence and prevalence ratios were presented according to sociodemographic variables, level of schooling, health condition/comorbidities, and self-evaluation of health, stratified by sex. Poisson regression was employed for crude and age-adjusted analyses.
The prevalence of overweight was of 47% for men and 39% for women, obesity was around 11% for both sexes. Direct association was observed between overweight and level of schooling among men and inverse association among women. Obesity was more frequent among men living with a partner and was associated neither with level of schooling nor skin color. The prevalence of overweight and obesity was higher among black women and women who lived with a partner. The presence of diabetes, systemic arterial hypertension and dyslipidemias, as well as the subject perceiving his/her health as regular or poor, were also reported by the interviewees with overweight or obesity.
While approximately one out of every two interviewees was classified as being overweight, obesity was reported by one out of every ten interviewed subjects. Socioeconomic and demographic variables, as well as reported morbidities, were associated with overweight and obesity. These results were similar to the ones found in other Brazilian studies.
评估超重和肥胖的流行情况及其相关因素。
本研究分析了 2006 年通过巴西首都和联邦区的 Vigilância de Fatores de Risco e Proteção para Doenças Crônicas por Inquérito Telefônico（VIGITEL--基于电话的慢性病风险和保护因素监测系统）调查的 18 岁及以上个体的数据。采用体质指数（BMI）来识别超重（BMI≥25kg/m2）和肥胖（BMI≥30kg/m2）。根据社会人口统计学变量、教育程度、健康状况/合并症和自我健康评估，按性别分层呈现了超重和肥胖的流行率和流行率比。采用泊松回归进行了粗分析和年龄调整分析。
男性超重的流行率为 47%，女性为 39%；肥胖的流行率在两性中均约为 11%。男性中，超重与教育程度呈直接相关，而女性中呈负相关。肥胖在与伴侣共同生活的男性中更为常见，与教育程度或肤色无关。超重和肥胖的流行率在黑人女性和与伴侣共同生活的女性中更高。受访者自述患有糖尿病、系统性动脉高血压和血脂异常，以及健康状况自评不佳或较差，与超重或肥胖有关。
尽管约有二分之一的受访者被归类为超重，但每 10 名受访者中就有 1 人报告肥胖。社会经济和人口统计学变量以及报告的合并症与超重和肥胖有关。这些结果与其他巴西研究相似。
