Hubungan Kualitas Tidur Dengan Derajat Keparahan Acne Vulgaris Pada Siswa Kelas Xii Di Sman 1 Cimalaka

Acne vulgaris is a chronic inflammatory disease of the pilosebaceous unit that frequently affects adolescents, and poor sleep quality is suspected to be associated with its severity. This study aimed to determine the relationship between sleep quality and the severity of acne vulgaris among 12th-grade students at SMA Negeri 1 Cimalaka. This quantitative study employed a descriptive-correlational design with a cross-sectional approach. The population consisted of 378 students, and a sample of 194 students was determined using the Slovin formula and selected via proportionate cluster random sampling. Sleep quality was measured using the Pittsburgh Sleep Quality Index (PSQI), while the severity of acne vulgaris was assessed using the Global Acne Grading System (GAGS). Both instruments were completed by the respondents themselves, either offline or online. Data were analyzed using the Spearman correlation test. A total of 131 respondents (67.5%) reported poor sleep quality, and 140 respondents (72.2%) had mild acne vulgaris. A significant relationship was found between sleep quality and the severity of acne vulgaris (rho = 0.273; p < 0.001), characterized by a positive direction and a weak correlation; specifically, poorer sleep quality tends to be associated with a higher severity of acne vulgaris. The cross-sectional design precludes conclusions regarding causality. Education on sleep quality could be incorporated into adolescent skin health promotion initiatives led by nurses.
