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 Brazilian cities, with a population aged 18 years or older. The body mass index (BMI) was calculated by the reported height and weight; overweight and obesity were considered as BMI >25 kg/m² and >30 kg/m², respectively. Temporal variation in overweight and obesity prevalence is presented for men and women, according to age group, schooling, stable relationship, and skin color. Poisson regression was used for the analysis. 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 socioeconomic 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 schooling. 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, especially among youngsters.
超重和肥胖是影响世界很大一部分人口的公共卫生问题。本研究旨在通过对巴西27个城市18岁及以上人口进行电话调查，描述2006年至2009年超重和肥胖患病率的趋势。根据报告的身高和体重计算体重指数（BMI）；超重和肥胖分别定义为BMI>25kg/m²和>30kg/m²。按年龄组、受教育程度、稳定关系和肤色呈现男性和女性超重和肥胖患病率的时间变化。采用泊松回归进行分析。2006年至2009年期间，每年的超重患病率分别为43.0%、42.7%、44.2%和46.6%。同期肥胖的趋势为：11.4%、12.7%、13.2%和13.8%。时间趋势因一些人口和社会经济变量而异。女性和年轻人中的患病率较高。时间趋势与受访者的关系状况无关，但白人女性和受教育年限较少者中的患病率较高。本研究结果证实迫切需要采取有效的预防和控制措施，因为这种上升趋势在短时间内出现，尤其是在年轻人中。
