- DHEA-S is the most abundant circulating steroid hormone in humans. Low concentrations of DHEA-S have been linked to several chronic diseases, but it is unclear if DHEA-S affects respiratory health. As part of the ALEC project [EU H2020 grant #633212], the associations of DHEA-S concentrations with lung function levels and decline were evaluated in women from the general population.Serum DHEA-S concentrations were measured in 2,250 women (28-57 years) participating in the European Community Respiratory Health Survey in 1999-2002. Associations of DHEA-S concentrations (categorized by age-adjusted quintiles) with FEV1, FVC, and the FEV1/FVC ratio were investigated using linear regression models adjusted for age, height, active and passive smoking, BMI, physical activity, education, menopausal status, and with study centre included as a random effect. Associations of DHEA-S concentrations with yearly decline in lung function (ΔFEV1, ΔFVC, ΔFEV1/FVC) were assessed in 1,340 women with spirometry data at follow-up in 2010-2014.The median (25th-75th percentile) concentration of DHEA-S was 4.2 µmol/L (2.9-6.0). The concentration of DHEA-S was significantly higher in current smokers and steadily declined with age. In fully adjusted models, women with low DHEA-S concentrations (below the 1st quintile) at baseline had worse FEV1 (-80mL, p<0.001) and FVC (-79mL, p=0.001) compared to women with higher DHEA-S levels. Low DHEA-S concentrations at baseline were associated with ΔFEV1/FVC (-0.08%/year, p=0.006), but not with ΔFEV1 or ΔFVC.The results suggest that low DHEA-S concentrations are associated with worse lung function in women, but have limited effects on lung function decline.
