Resumo
Objetivo: Determinar se há associações entre o nível de atividade física na vida diária (AFVD) e a função pulmonar em tabagistas adultos. Métodos: Foram selecionados 62 tabagistas adultos de um estudo epidemiológico, realizado na cidade de Santos (SP). Os participantes realizaram o teste de espirometria forçada para a avaliação da função pulmonar. O nível de AFVD foi avaliado pelo Questionário Internacional de Atividade Física e por acelerometria triaxial (aparelho utilizado por sete dias). O nível mínimo de AFVD, em termos de quantidade e intensidade, foi definido como 150 min/semana de atividade física moderada a vigorosa durante o monitoramento. As correlações entre as variáveis estudadas foram avaliadas pelo coeficiente de correlação de Pearson ou de Spearman
conforme a distribuição das variáveis. A influência de AFVD nas variáveis espirométricas foi avaliada por meio de análise de regressão múltipla linear. O nível de significância foi estipulado em 5%. Resultados: Quando avaliados todos os preditores corrigidos para fatores de confusão e utilizando dados da função pulmonar como variáveis de desfecho, não foram observadas associações significativas entre a inatividade física avaliada por acelerometria e os índices espirométricos. As análises mostraram valores inferiores da CVF em participantes com hipertensão arterial e da relação VEF1/CVF nos participantes com diabetes mellitus. Os participantes obesos e os dislipidêmicos apresentaram valores inferiores de CVF e VEF1. Conclusões: Nossos resultados sugerem que a inatividade física apresenta associação pouco consistente com a função pulmonar de tabagistas
adultos. A carga tabágica, assim como comorbidades cardiovasculares e metabólicas, deveriam ser priorizadas em estratégias preventivas da DPOC.
Objective: To determine whether the level of physical activity in daily life (PADL) is associated with pulmonary function in adult smokers. Methods: We selected 62 adult smokers from among the participants of an epidemiological study conducted in the city of Santos, Brazil. The subjects underwent forced spirometry for pulmonary function assessment. The level of PADL was assessed by the International Physical Activity Questionnaire and triaxial accelerometry, the device being used for seven days. The minimum level of PADL, in terms of quantity and intensity, was defined as 150 min/week of moderate to vigorous physical activity. Correlations between the studied variables were tested with Pearson’s or Spearman’s correlation coefficient, depending on the distribution of the variables. We used linear multiple regression in order to analyze the influence of PADL on the spirometric variables. The level of significance was set at 5%. Results: Evaluating all predictors, corrected for confounding factors, and using pulmonary function data as outcome variables, we found no significant associations between physical inactivity, as determined by accelerometry, and spirometric indices. The values for FVC were lower among the participants with arterial hypertension, and FEV1/FVC ratios were lower among those with diabetes mellitus. Obese participants and those with dyslipidemia presented with lower values for FVC and FEV1. Conclusions: Our results suggest that there is no consistent association between physical inactivity and pulmonary function in adult smokers. Smoking history should be given special attention in COPD prevention strategies, as should cardiovascular and metabolic comorbidities.
