Socio-demographic determinants of low sexual desire and hypoactive sexual desire disorder: a population-based study in Iran.

BACKGROUND Various socio-demographic factors have been introduced as the determinants of Low Sexual Desire (LSD), but whether these variables can also contribute to the Hypoactive Sexual Desire Disorder (HSDD), remains uncertain. In this study, we sought to identify the socio-demographic determinants of LSD and HSDD in Iranian women of reproductive age. METHODS This was a population-based, cross-sectional study of 1000 married Iranian women of reproductive age (16-49 years) who met the inclusion criteria. The participants were chosen using the systematic random sampling method from all the healthcare centres in the city of Sari, Iran. LSD was defined as a score no higher than 33 on the Sexual Interest and Desire Inventory-Female (SIDI-F). The sexually-related personal distress was considered as a score of at least 11.0 on the Female Sexual Distress Scale-Revised (FSDS-R), and HSDD was determined based on the sum of those scores. Descriptive statistics were used to describe the socio-demographic characteristics and a chi-square test was run for data analysis using grouping variables. Multivariate logistic regression test was also employed to adjust the effect of confounding variables. RESULTS The mean score of sexual interest/desire among women was 30.6 ± 10.5. After adjusting the effect of confounding variables, logistic regression showed that socio-demographic variables including age at first intercourse, length of marriage and the level of satisfaction with income were significantly associated with both LSD and HSDD (P < 0.01). While advancing age (P < 0.001) and body mass index (P < 0.01) were just predictors of LSD. CONCLUSION Some socio-demographic factors could predict LSD in women, while they were not associated with HSDD. In other words, some factors associated with LSD do not instigate sexually-related personal distress, which is one of the criteria necessary for the diagnosis of HSDD.
