摘要超重和肥胖是影响世界人口的重要公共卫生问题。这项研究的目的是通过对巴西27个城市18岁或以上人口的电话调查，描述2006年至2009年超重和肥胖流行率的趋势。根据报告的身高和体重计算体重指数（BMI）;超重和肥胖分别被视为BMI ≥ 25 kg/m2和≥ 30 kg/m2。根据年龄组、学校、稳定的关系和肤色，呈现了男性和女性超重和肥胖患病率的时间变化。采用Poisson回归进行分析。2006 - 2009年各年超重率分别为43.0%、42.7%、44.2%和46.6%。在同一时期，肥胖的趋势是：11.4%、12.7%、13.2%和13.8%。时间趋势因某些人口和社会经济变量而异。妇女和年轻人的患病率较高。时间趋势与受访者的关系状况无关，但白色女性和受教育年限较短的女性患病率较高。本研究结果证实了有效预防和控制措施的迫切需要，因为这种增长趋势在短时间内发生，特别是在青少年中。
Abstract Overweight and obesity are public health issues that affect an important part of the world population. This study aims at describing the trends in overweight and obesity prevalence rates from 2006 to 2009, by means of telephone surveys in 27 Brazil-ian cities, with a population aged 18 years or older. The body mass index (BMI) was calcu-lated by the reported height and weight; overweight and obesity were considered as BMI ≥25 kg/m2 and ≥30 kg/m2, respective-ly. Temporal variation in overweight and obesity prevalence is presented for men and women, according to age group, school-ing, stable relationship, and skin color. Poisson regression was used for the analy-sis. Overweight prevalence was 43.0, 42.7, 44.2 and 46.6%,for each year of the period from 2006 to 2009, respectively. For obesity, in the same period, the trend was: 11.4, 12.7, 13.2 and 13.8%. The temporal trend varied in relation to some demographic and socio-economic variables. The prevalence was higher among women and young adults. The temporal trend was independent of the relationship status of the interviewees, but the prevalence was higher among white women and those with less years of school-ing. The results in this study confirmed the urgent need for effective prevention and control measures, as the increasing trend is occurring in a short period of time, especial-ly among youngsters.
