Association Between Body Mass Index and Female Sexual Dysfunction: A Cross-sectional Study from the Data Registry on Experiences of Aging, Menopause, and Sexuality

Abstract

Background Obesity and female sexual dysfunction (FSD) are prevalent conditions, and both are associated with significant adverse effects on health and well-being. Aim To investigate the association between body mass index and FSD, as well as potential moderators. Methods This cross-sectional study was performed by analyzing medical records of 6,688 women seeking consultation for menopause-related or sexual health–related concerns at women’s health clinics at Mayo Clinic Rochester, MN, and Scottsdale, AZ, between May 1, 2015, and September 15, 2019. Outcomes Female sexual function was assessed by the Female Sexual Function Index, and sexual distress was assessed by the Female Sexual Distress Scale-Revised. Results Being overweight or obese was associated with a lack of sexual activity. Among sexually active women, those who were overweight or obese had lower Female Sexual Function Index total scores and sexual function domain scores (indicating worse sexual function), including sexual arousal, lubrication, satisfaction, orgasm, and pain, and higher levels of sexual distress than those with normal weight. However, on multivariable analysis, these associations were found to be mediated by other factors, including age, level of education, reproductive stage, medication use, and mood disturbances, which are known to impact body weight and sexual function in women. Clinical Implications Overweight and obesity were associated with sexual inactivity and greater odds of having FSD, which should prompt proactive assessment of sexual function. Strengths and Limitations The strengths of this study include the large cohort size and assessment of sexual problems in addition to sexual distress, a key component of the definition of sexual dysfunction. This study also took into account multiple potential moderating factors. Limitations include the cross-sectional design, which precludes determination of causality as well as lack of diversity in the cohort, potentially limiting generalizability of results. In addition, sexual function was not assessed in women reporting no recent sexual activity, which may confound results. Conclusion Overweight/obesity and FSD are highly prevalent conditions, which appear to be indirectly associated. These results highlight the need to identify and address FSD in all overweight and obese women, with particular attention to potential contributing factors.

Prevalence and predictors of female sexual dysfunction among sexually active women in the diabetes prevention program outcomes study

“…Previous studies investigating the association between BMI and sexual dysfunction in women have demonstrated inconsistent findings with some studies showing an association 43,44 and others not 45,46 . The significant variability is most likely attributable to methodological differences as well as the lack of opportunity for direct comparison due to the use of heterogeneous patient‐reported sexual function measures and varying cutoffs for the definition of sexual dysfunction.…”

Consistent with our current findings of reduced FSD in women with increasing mean BMI, in the English Longitudinal Study of Ageing, a sample of 2737 women aged ≥50 years, women with overweight reported a higher frequency of sexual intercourse in the last month compared with those who were normal weight.…”

Sexual dysfunction and its associated factors among reproductive-age women at Gurage Zone, Southern Ethiopia, 2023

“…Similarly, several studies reported the existence of an association between obesity and sexual inactivity. A case-control study conducted in Iran observed particularly that there was a strong and inverse correlation between BMI and arousal, lubrication, and orgasm [ 46 – 48 ]. Inconsistent with our study finding some studies had failed to show the association between FSD and BMI [ 49 , 50 ].…”

Prevalence and associated risk factors for sexual dysfunction among postmenopausal women: a study from Iran

“…The selection of independent variables was based on findings from previous investigations. It has been shown that age, BMI, sexual frequency, anxiety, and depression could have a significant effect on the sexual function of postmenopausal women [ 18 – 21 ]. Of these, although the inclusion of sexual frequency in the model seems somewhat teleological (e.g.…”
