Obesity is a complex multifactorial disease that has been associated with higher morbidity and mortality. This study aimed to compare changes in body mass index (BMI) and obesity prevalence between two cross-sectional samples of Brazilian women. Furthermore, retrospective assessments of lifetime body weight changes were explored. Two independent population-based cross-sectional surveys were conducted in 2003 (first survey) and 2015 (second survey) with women living in the urban area city in southern Brazil. Both surveys had a similar design and included 981 women aged 20-60 years. Mean BMI and the presence of obesity (BMI ≥ 30 kg/m) were estimated. Additionally, lifetime body weight change was obtained for the retrospective longitudinal assessment. After 12 years, there was a significant increase from 25.9 ± 5.3 kg/m to 28.1 ± 6.2 kg/m in mean BMI. Between 2003 and 2015, the prevalence of obesity increased by 73% (18.0%; 95% CI: 15.8-20.6 vs. 31.2%; 95% CI: 28.3-34.1; < 0.001). The means of estimated cumulative body weight gain from 15 to 50 years were 15.2 kg (95% CI: 13.3-17.1) and 17.2 kg (95% CI: 15.5-18.9) in 2003 and 2015, respectively; the greater cumulative difference between the two periods was observed at 40 years of age (3.3 kg). There was a significant increase in the mean BMI and prevalence of obesity between 2003 and 2015. Moreover, women experienced higher body weight gain during their lives in both survey periods, mainly in early adulthood.
肥胖是一种复杂的多因素疾病，与更高的发病率和死亡率有关。本研究旨在比较巴西女性两个横断面样本的体重指数（BMI）和肥胖患病率的变化。此外，还探讨了终生体重变化的回顾性评估。2003 年（第一次调查）和 2015 年（第二次调查）进行了两次独立的基于人群的横断面调查，调查对象为居住在巴西南部城市城区的女性。两次调查的设计相似，共纳入 981 名年龄在 20-60 岁的女性。估计了平均 BMI 和肥胖的存在（BMI≥30kg/m）。此外，还获得了终生体重变化的回顾性纵向评估。12 年后，平均 BMI 从 25.9±5.3kg/m 显著增加到 28.1±6.2kg/m。2003 年至 2015 年间，肥胖患病率增加了 73%（18.0%；95%CI：15.8-20.6 与 31.2%；95%CI：28.3-34.1；<0.001）。从 15 岁到 50 岁估计的累积体重增加平均值分别为 15.2kg（95%CI：13.3-17.1）和 17.2kg（95%CI：15.5-18.9），在 2003 年和 2015 年分别为 20.0kg（95%CI：17.4-22.7）和 22.2kg（95%CI：19.6-24.7），两个时期之间的累积差异在 40 岁时最大（3.3kg）。2003 年至 2015 年间，平均 BMI 和肥胖患病率均显著增加。此外，在两次调查期间，女性在一生中的体重增加更多，主要是在成年早期。
