Age, Body Mass and Physical Activity Determinants of Facial Acne Severity among Southern Nigerian Adolescents and Young Adults


Objective: To explore the relationship between severities of acne with age, body mass index (BMI) and physical activity index (PAI) of the patients.

Methods: The study employed a cross-sectional design. Acne patients were recruited through quota sampling across Faculties of a University, 120 subjects met the inclusion requirements and gave individual consent; however, only 105 completed the study. A 25 cm2 quadrant, Global Acne Grading Scale (GAGS), Kaiser Physical Activity Survey (KPAS) and BMI apparatus were used to measure: acne lesion count and density, facial distribution and severity, PAI, and BMI, respectively. Multiple regression, and Spearman’s correlation were used for inferential statistical analysis.

Results: Subjects’ characteristics were: age (22 ± 4 years), BMI (25.3 ± 3.5), PAI (2.5 ± 0.4) and 5 ± 1.7 acne eruptions per 25 cm2 of face. Multiple regression showed that age, BMI and PAI significantly predicted acne severity, F (3,101) = 4.272, p = 0.012, R2 = 0.293. Conversely, only age (ρ = -0.513, p = 0.002, CI = 99%) had a significant (inverse) relationship with acne severity; there is no significant relationship between acne and BMI (ρ = 0.034, p = 0.846, CI = 95%) or PAI (ρ = -0.313, p = 0.067, CI = 95%).

Conclusion: Age of subjects had a significant correlation with acne severity. However, BMI and PAI had no significant relationship with acne
