Abstract

Background
Sexual dysfunction frequencies and diagnostic indicators among older populations are relevant for public health measures, but evidence from large population-based studies is still scarce.

Aim
To determine sexual dysfunction frequencies for women and men according to the Diagnostic and Statistical Manual of Mental Disorders (fifth edition; DSM-5) among 45- to 74-year-old participants of the population-based Hamburg City Health Study and the factors associated with sexual dysfunction diagnoses.

Methods
We determined sexual dysfunction frequencies according to the DSM-5 and the factors associated with sexual dysfunction diagnoses (quality/avoidance of and discomfort during sex) among 45- to 74-year-olds from 7786 participants of the population-based Hamburg City Health Study. We analyzed cross-sectional self-report questionnaire data collected between 2016 and 2019 using descriptive statistics, comparative tests (Fisher test, Mann-Whitney U test), and logistic regression.

Outcomes
Outcomes included sexual dysfunction frequencies - specifically, sexual difficulties experienced frequently or more often, over at least six months in the last year, causing severe or very severe distress, and not associated with physical health or relationship problems - and items on quality/avoidance of and discomfort during sex.

Results
Participants’ median age was 62.0 years (IQR, 14) and 51.1% were women. The frequency of sexual dysfunction according to the DSM-5 was 9.3% (95% CI, 8.3%-10.4%) in women and 6.2% (95% CI, 5.4%-7.1%) in men, with women’s sexual interest/arousal and men’s erectile disorder being most common. Sexual dysfunction rates increased with age: whereas complaints were more frequent among women than men in the younger groups, participants aged ≥65 years with a sexual dysfunction were more often men. Quality/avoidance of and discomfort during sex were significantly associated with a diagnosis of sexual dysfunction.

Clinical Implications
Results suggest that sexual dysfunction caused by other than physical health or relationship factors is important to consider in this population. In addition, the avoidance of, perceived quality of, and discomfort during sex serve as valuable diagnostic indicators for the presence of sexual dysfunction.

Strengths and Limitations
This study draws on robust data from a large sample to give valuable insight on the frequency of sexual difficulties and dysfunctions as defined by DSM-5 criteria. Limitations represent the restriction to self-report questionnaire data, the focus on participants living in a metropolitan area, and the lack of experience of sexual difficulties due to a lack of sexual activity not being taken into account.

Conclusion
The study provides estimates for DSM-5 sexual dysfunction frequencies among Germans from a metropolitan area and points to the diagnostic value of age-related changes as well as the quality/avoidance of and discomfort during sex.
