Low socioeconomic position and neighborhood deprivation are associated with uncontrolled asthma in elderly

Abstract : BACKGROUND: While uncontrolled asthma in adults is frequent in Europe, the impact of socioeconomic position (SEP) was little investigated. We aimed to investigate the respective association of individual- and area-level SEP with uncontrolled asthma among French elderly women. METHODS: Analyses were conducted in the Asthma-E3N study, among participants with current asthma (i.e., asthma attacks, treatment, or symptoms in previous year). Asthma control was evaluated using Asthma Control Test (uncontrolled: score ≤19); SEP was defined at both individual- and area-level, using educational level (low, medium, high), the French Deprivation index (tertiles defined at national level), and by merging them in a combined-SEP index. Associations between SEP and asthma control were estimated for 2258 women by logistic regression adjusted for age. Analyses were stratified by asthma controller medication use estimated through a drug reimbursement database. RESULTS: Women were 70 years on average and 24% had uncontrolled asthma. A low educational level (11%) was associated with an increased risk of uncontrolled asthma [odds ratio (95% confidence interval) = 1.9 (1.4,2.6)], especially among women not using controller medication [3.1 (1.9,5.1)]. Using the combined-SEP index, the highest risk of uncontrolled asthma was observed among women with the most disadvantaged socioeconomic profile (low educational level and low-SEP neighborhood) [2.5 (1.5,4.2)]. CONCLUSIONS: Women with low SEP had more often uncontrolled asthma, which might be partly explained by inadequate asthma treatment. To achieve the best management of asthma for elderly patients, a specific attention should be given not only to disadvantaged population and neighborhoods, but also to disadvantaged populations in affluent neighborhoods.
