Prevalence and predictors of female sexual dysfunction: a protocol for a systematic review

BACKGROUND: Sexual function is an essential component of life. For this reason, sexual dysfunction can have a negative impact on the wellbeing of men and women alike. Since the turn of the 21st century, research on female sexual dysfunction (FSD) has gained momentum. While FSD is often assessed in people with ill health, sexual dysfunction is an illness of its own entity and is also prevalent in non-patient populations. A critical review of current literature on female sexual dysfunction in general populations will shed light on possible determinants as well as at-risk groups. Thus, the aim of this systematic review is to assess the prevalence and the predictors of female sexual dysfunction in general populations. METHODS/DESIGN: A systematic review of current literature on FSD will be performed. Studies will be considered for review if they report quantitative data on the prevalence of female sexual dysfunction. Outcome measures will include the prevalence of FSD, the time period assessed, and significant predictors for each domain of FSD. The scientific databases MEDLINE, EMBASE, PsycINFO, and Web of Science will be systematically searched in cooperation with a medical research librarian. Hand searches for further relevant publications will also be undertaken. Screening of search results and extraction of data from included studies will be conducted cooperatively by two authors. The quality of the studies will be appraised and documented. Results will be compiled and presented in evidence tables. DISCUSSION: In the past decade, population-based studies on female sexual dysfunction have increased in number and grown more varied in their cultural settings. This review aims to provide a current overview of the prevalence of female sexual dysfunction in populations from various countries, cultures, and age groups in order to provide a better understanding of its effect on women's lives today.
