To evaluate the anthropometric data obtained for residents of the city of São Paulo, Brazil, in a study of Latin America conducted in two phases (baseline, in 2003, and follow-up, in 2012).
This was an analysis of data obtained for São Paulo residents in a two-phase population-based study evaluating the prevalence of COPD and its relationship with certain risk factors among individuals ≥ 40 years of age. The anthropometric data included values for weight, height, body mass index (BMI), and waist circumference. In the follow-up phase of that study, the same variables were evaluated in the same population sample as that of the baseline phase.
Of the 1,000 São Paulo residents enrolled in the baseline phase of that study, 587 participated in the follow-up phase, and 80 (13.6%) of those 587 subjects had COPD. Comparing the baseline and follow-up phases, we found increases in all anthropometric measures in both groups (COPD and non-COPD), although the differences were significant only in the non-COPD group. The subjects with mild COPD showed increases in weight and BMI (Δweight = 1.6 ± 5.7 and ΔBMI = 0.7 ± 2.2), whereas those with moderate or severe COPD showed reductions (Δweight = -1.7 ± 8.1 and ΔBMI = -0.4 ± 3.0), as did those with severe or very severe COPD (Δweight = -0.5 ± 5.4 and ΔBMI = -0.8 ± 3.3).
Between the two phases of the study, the subjects with mild COPD showed increases in weight and BMI, whereas those with a more severe form of the disease showed reductions.
评估在巴西圣保罗市进行的一项拉丁美洲研究中获得的居民人体测量学数据，该研究分两阶段进行（基线期，2003 年；随访期，2012 年）。
这是一项对圣保罗居民进行的基于人群的两阶段研究数据的分析，该研究评估了 COPD 的流行情况及其与≥40 岁个体某些危险因素的关系。人体测量学数据包括体重、身高、体重指数（BMI）和腰围。在该研究的随访阶段，对同一人群样本评估了相同的变量。
在该研究的基线阶段，有 1000 名圣保罗居民被纳入研究，其中 587 名居民参加了随访阶段，80 名（13.6%）参与者患有 COPD。比较基线期和随访期，我们发现两组（COPD 和非 COPD）的所有人体测量指标均有所增加，尽管非 COPD 组的差异有统计学意义。轻度 COPD 患者的体重和 BMI 增加（体重变化=1.6±5.7，BMI 变化=0.7±2.2），而中度或重度 COPD 患者的体重和 BMI 减少（体重变化=-1.7±8.1，BMI 变化=-0.4±3.0），严重或极严重 COPD 患者的体重和 BMI 也减少（体重变化=-0.5±5.4，BMI 变化=-0.8±3.3）。
在研究的两个阶段之间，轻度 COPD 患者的体重和 BMI 增加，而疾病更严重的患者则减少。
