Associated Determinants of Sexual Dysfunctions in Non-Specific Low Back Pain Patients in Cameroon: A Cross-Sectional...

Non-specific low back pain (NSLBP) is a significant factor involved in the onset of sexual dysfunctions (SDs). However, studies demonstrating the correlation between these 2 conditions are rare. This study aimed to determine the prevalence and factors associated to SDs in patients suffering from NSLBP in Cameroon.

A cross-sectional study was conducted among patients suffering from NSLBP in the 3 main town (Yaoundé, Douala and Bafoussam) of Cameroon. Clinical characteristics and sexual activity of these patients were evaluated using validated questionnaires such as the Oswestry Disability Index, the Hospital Anxiety and Depression Scale, the Pain Catastrophizing Scale, the Male sexual Health-Questionnaire, and the Female Sexual Function Index.

Data from 409 patients (233 men and 176 women) were collected and included in this study. The overall prevalence of SDs related to NSLBP was 43%. The most affected sexual activity domains were desire (2.7 ± 1.4) and excitement (3.2 ± 1.4) in women. In men, desire (15.2 ± 5.7) and sexual satisfaction (15 ± 6.8) were most affected. Several associations were found between SD in NSLBP patients and some variables such as: overweight (odds ratio [OR] = 1.882, P = .005), female (OR = 1.518, P = .03), pain intensity (OR = 1.365, P = .0001), pain catastrophizing (OR = 1.076, P = .0003), hypoflexibility (OR = 1.029, P = .0009), reduced erector spinae (OR = 0.984, P = .0009), abdominal muscle strength (OR = 0.983, P = .016), depression (OR = 1.177, P < .0001), anxiety (adjusted odds ratio [aOR] = 1.168, P < .0001), and disability (OR = 1.165, P < .0001).

The relatively high prevalence of SDs related to NSLBP highlights the close relationship between these 2 conditions and their associated factors in Cameroon. These results highlight many factors that must be taken into account in the management of SDs related to NSLBP.
