Steroid hormone levels associated with passive and active smoking

Abstract

Context Cigarette tobacco smoke is a potent environmental contaminant known to adversely affect health including fertility and pregnancy. Objective To examine the associations between second-hand cigarette tobacco-smoke exposure, or active smoking and serum concentrations of steroid hormones using tandem mass spectrometry. Design Healthy women (18–45 y) from the general community in the Metropolitan Washington, DC were recruited at the follicular stage of their menstrual cycle. Participants were assigned to one of three study groups: active smokers (N= 107), passive smokers (N= 86), or non-smokers (N= 100). Classifications were based on a combination of self-reporting and serum cotinine concentrations. Methods Serum androgens, estrogens, progestins, androstenedione, aldosterone, cortisol, corticosterone, dehydroepiandrosterone (DHEA), dehydroepiandrosterone sulfate (DHEAS), 11-deoxycortisol and 25-hydroxy-vitamin D3 (25-OHVitD3) and cotinine were measured by isotope dilution tandem mass spectrometry (LC/MS/MS) (API-5000). Kruskal–Wallis tests were used to assess median differences among the three groups, with Dunn’s multiple comparison test for post hoc analysis. Results Serum estrone, estradiol, and estriol concentrations were lower in active and passive smokers than in non-smokers. The three study groups differed significantly in serum concentrations of 16-OHE1, aldosterone and 25-OHVitD3, as well as in the ratios of many of the steroids. Pair-wise comparison of the groups demonstrated significant differences in hormone concentrations between (i) smokers and nonsmokers for aldosterone: (ii) passive smokers and non-smokers for aldosterone, progesterone and estriol. Moreover, for smokers and passive smokers, there were no significant differences in these hormone concentrations. Conclusions Smoke exposure was associated with lower than normal median steroid hormone concentrations. These processes may be instrumental in explaining some adverse effects of tobacco smoke on female health and fertility.

Autonomic control of cardiovascular system in pre- and postmenopausal women: a cross-sectional study

“…It is known that DHEAS level decreases with age (30). It is also known that smoking has an influence on steroid hormone concentrations (32). However, we did not find such an influence in our study.…”

Associations between lifetime tobacco exposure with infertility and age at natural menopause: the Women's Health Initiative Observational Study

“…Tobacco toxins affect multiple sites in hormonal synthesis and overall physiology to the deleterious effect on fecundity, fetal survival and age at natural menopause 1 7 8 32. Recent studies support the hypothesis that tobacco exposure through active smoking adversely affects fertility 1 4 6 21 32.…”

“…In the case of age at natural menopause, about half of studies examining the associated biological factors with the outcome show significant associations with active and passive smoking 7 9 11 12 14. Yet, many of the studies are small and do not address the challenges of studying SHS exposure, of which there are two main issues.…”

Vitamin D status in apparently healthy medication-free Slovaks: Association to blood pressure, body mass index, self-reported smoking status and physical activity

“…The exact mechanisms by which the constituents of tobacco smoke affect vitamin D metabolism are still unclear, but adverse effects on the level of 25(OH)D 3 synthesis are anticipated (42). In smokers, less sun exposure due to shorter outdoor activities might also not be excluded (41).…”
