Abstract

Objective: 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).

Methods: 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.

Results: 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).

Conclusions: 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.

Objetivo:: Avaliar a evolução dos dados antropométricos obtidos em uma pesquisa latino-americana realizada em duas fases (basal, em 2003, e seguimento, em 2012) na cidade de São Paulo.

Métodos:: Estudo de base populacional que avaliou indivíduos com idade ≥ 40 anos com o objetivo de definir a prevalência da DPOC e sua relação com alguns fatores de risco. A avaliação antropométrica incluiu medições de peso, altura, índice de massa corpórea (IMC) e circunferência abdominal. Foram avaliadas as mesmas variáveis na mesma população na fase de seguimento.

Resultados:: Dos 1.000 indivíduos incluídos inicialmente, 587 participaram da fase de seguimento; desses, 80 (13,6%) tinham DPOC. Entre a avaliação inicial e a de seguimento ambos os grupos (DPOC e não DPOC) apresentaram aumentos nas medidas antropométricas, mas esses somente foram significativos no grupo não DPOC. Os indivíduos com DPOC leve tiveram aumentos de peso e IMC (Δpeso = 1,6 ± 5,7 kg e ΔIMC = 0,7 ± 2,2 kg/m2) enquanto aqueles com doença moderada ou grave tiveram reduções dessas medidas (DPOC moderada: Δpeso = −1,7 ± 8,1 kg e ΔIMC = −0,4 ± 3,0 kg/m2; e DPOC grave ou muito grave (Δpeso = −0,5 ± 5,4 kg e ΔIMC = −0,8 ± 3,3 kg/m2).

Conclusões:: Entre as duas fases da pesquisa, os pacientes com DPOC leve tiveram aumento de peso e IMC, enquanto aqueles com doença mais grave apresentaram perda ponderal e redução do IMC.
