Abstract

INTRODUCTION: Few studies have described the prevalence of and lung function decline among those with a restrictive spirometric pattern (RSP) in low- and middleincome countries.METHODS: We analyzed prospective data from 3055 adults recruited across four diverse settings in Peru over a 3-year period. Multivariable logistic regression was used to study the association between the presence of restriction and associated risk factors. Multivariable linear mixed models were used to determine lung function decline.RESULTS: Among 3055 participants, the average age was 55.4 years (SD 12.4); 49% were male. Overall prevalence of RSP was 4.7%, ranging from 2.8% (Lima) to 6.9% (Tumbes). The odds of having RSP were higher among those who lived in a rural environment (OR 2.19, 95%CI 1.43-3.37), had a diagnosis of diabetes (OR 1.94, 95%CI 1.10-3.40) and among women (OR 2.09, 95%CI 1.41-3.09). When adjusting for baseline lung function, adults with RSP had accelerated decline in forced expiratory volume in 1 s (FEV1) compared with non-obstructed, non-restricted individuals. D I SCUS S ION: RSP is prevalent particularly among women and in individuals living in rural settings of Peru. When adjusted for baseline lung function, participants with RSP had accelerated rates of FEV1 decline.Our findings are consistent with the notion that RSP is an insidious inflammatory condition with deleterious effects of lung function decline.
