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

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.

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

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.

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.

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.
