Impact of Lifestyle and Dietary Habits on the Prevalence of Acne Vulgaris: A Cross-Sectional Study From Saudi Arabia.

Abstract

Background Acne vulgaris is a prevalent dermatological condition worldwide, with its impact significantly influenced by various genetic, environmental, and lifestyle factors. Despite its global prevalence, data on acne's prevalence and risk factors in Saudi Arabia remain sparse. This study aims to fill this gap by examining the prevalence of acne vulgaris and identifying associated lifestyle and environmental risk factors within the Saudi population. Methodology Employing a cross-sectional survey-based design, this study collected data from a representative sample of the Saudi population aged 18 years and older. Participants were selected through stratified random sampling and completed a self-administered online questionnaire covering demographic information, lifestyle factors, and acne history. Statistical analyses, including descriptive statistics, chi-square tests, and multivariable logistic regression, were utilized to identify significant risk factors associated with acne vulgaris. Results The survey, completed by 1,983 participants, revealed a diverse age distribution with a slight predominance of the 21-25-year age group (32.5%). Gender distribution was nearly balanced (52% female, 48% male), and the majority were single (67.3%). Lifestyle assessments indicated varied water intake, with a significant portion consuming less than 1-2 L per day. Sleep duration for most fell within the 5-7 hours range. Fast food consumption was frequent among 24% of respondents, and physical activity levels showed 40% of participants exercised minimally. Notably, 72% reported a history of acne, predominantly beginning between ages 16 and 20. Acne was mainly mild to moderate in severity and primarily affected the face. Treatment was sought by 60%, with a preference for topical solutions. Awareness around acne causes was moderate, with a high consensus on the impact of stress and diet on acne development. Conclusions Acne vulgaris in Saudi Arabia is significantly associated with various modifiable lifestyle factors, suggesting that interventions focusing on lifestyle modifications may be effective in managing and preventing acne. This study advocates for the integration of lifestyle counseling into acne treatment protocols, offering a holistic approach to managing this pervasive condition.
