Striae Distensae: A Cross-Sectional Study of Risk Factors and Quality of Life among Nigerians.

Background: Striae distensae is a common affliction of darkly pigmented skin. The pattern, risk factors and impact of striae distensae on the Quality of Life (QoL) have not been widely examined.

Objective: To document the prevalence, pattern, risk factors and impact of striae distensae on the QoL of sufferers.

Methods: 520 adults were included through a crosssectional design. Demographic and striae distensae-related clinical parameters were documented and QoL evaluated using Skindex-29 and DLQI.

Results: Mean age of participants was 24.10±5.44years. Participants with striae distensae were significantly females (71.9% vs 28.1%, p<0.001) and mild (61.9%) and moderate (32.5%) striae distensae were prevalent. Higher total mean ± SD and mean ranked scores correlated with single status (p<0.001 and p=0.017) and striae distensae severity (p<0.001 and p=0.035) on Skindex and DLQI, respectively. Singles with striae distensae had significantly higher scores on symptom/feeling (p<0.001), daily activities (p=0.003), relationship (p=0.043), leisure (p=0.004), treatment (p=0.011) and work/school (p=0.014) on DLQI. Striae distensae was associated with higher emotion (p<0.001) and functioning (p<0.001) scores on Skindex-29. In regression analysis, age < 30years OR-1.219 (CI: 1.062, 1.400, p=0.005), was a predictor of severe QoL impairment on Skindex-29 and age <30 years OR-1.130 (CI: 1.022, 1.250, p=0.017), obesity OR=1.091, 95% (CI 1.008;1.181, p=0.032) and concern about striae distensae OR-2.482 (CI: 1.392, 4.425, p=0.002) on DLQI.

Conclusion: Psychologic evaluation might be indicated in cases of singles with moderate-severe striae distensae and impaired QoL. Predictors of impaired QoL include young age, high BMI, and concerns about striae distensae.
