Methods: We performed a cross-sectional analysis using data from 1,954 population controls (aged 24-85 y) in 12 provinces of Spain who were enrolled in the Multi Case-Control Spain study (2007-2013). Data were collected from a questionnaire conducted face-to-face by trained personnel. We collected information on sociodemographic factors, lifestyle, sleep patterns, reproductive history, and occupational history. Results: Overall, 48.5% of Spanish women reported ever use of hormonal contraception, and 9.8% of women in the postmenopausal group reported use of postmenopausal hormone therapy. Younger cohorts used hormonal contraception for a longer period, whereas postmenopausal hormone therapy use dramatically dropped in the 2000s. Women with higher education levels (including education of partners) and smoking history were the most probable users of hormonal contraception, whereas inverse associations were observed among housewives, obese women, and nulliparous women. Postmenopausal hormone therapy use was associated with a surgical or therapeutic cause of menopause and with occupational history of rotating shifts. Conclusions: In this Spanish population, several demographic, lifestyle, occupational, and reproductive factors are associated with use of hormonal compounds. Characterizing hormonal users and monitoring trends in the use of these hormonal compounds are essential from a public health perspective." }
