The objective of this study was to assess the prevalence and risk factors of female sexual dysfunctions across a selection of social groups. In all, 1219 women in the community, aged 18 y or
older, answered a 38-question self-applicable questionnaire. Statistical analysis was performed using multivariate logistic regression. The average age was 35.6 y (s.d.=12.31) and the
average number of sexual intercourses was 2.8 (s.d.=1.94) a week. At least one sexual dysfunction was reported by 49% of the women; lack of sexual desire (LSD) by 26.7%; pain during sexual
intercourse (PSI) by 23.1% and orgasmic dysfunction (OD) by 21%. Women aged over 40 y represented an LSD and OD risk factor, whereas women aged over 25 y showed less likelihood of presenting
PSI. The educational level was inversely correlated with the risk of LSD, OD and PSI. Depression and cardiopathies increased PSI occurrences and women with diabetes mellitus showed a higher
probability of developing LSD and OD. In conclusion, almost half the women had at least one sexual dysfunction, and prevalence increased with age and lower educational levels. Preventive
medical care for the female population, mainly for patients with chronic and/or degenerative diseases, considerably reduced the chances of sexual dysfunction.
