Smoking exerts influences on the secretion of several hormones which are abnormal in obesity. Previous studies have mainly been performed in non-obese men, and data from non-obese and obese women are scarce. The aim of the present study was therefore to identify the effect of smoking on hormone secretions in obese and lean female smokers. The study was performed in 10 obese and 8 lean, premenopausal, healthy smokers. All subjects were tested once under experimental and once under control conditions (not smoking) in randomized order. The women smoked two non-filtered cigarettes during 4 minutes each. Blood pressure and heart rate were measured 30 minutes before smoking, at the start of smoking (time 0) and then after 5, 10, 20, 30, 45 and 60 minutes. Blood samples were taken for determination of serum concentrations of adrenocorticotropic hormone (ACTH), cortisol, prolactin (PRL), growth hormone (GH) and thyroid stimulating hormone (TSH) at the same time points except at 5 minutes. Heart rate rose in both groups during smoking. Systolic and diastolic blood pressure was increased only in the obese subjects. Cortisol and ACTH increased in both groups, while TSH, PRL and GH were unchanged in both groups. We conclude that lean and obese smoking women seem to respond rather similarly to smoking in the hemodynamic and endocrine variables measured in this report with the possible exception of blood pressure where the obese women tended to show more pronounced increases.
