Abstract
Background: The effects of childhood obesity or weight gain on the development of early-onset follicular occlusion triad (FOT) among children, which includes hidradenitis suppurativa (HS), acne conglobata (AC), and dissecting cellulitis of the scalp (DCS), remain unknown.
Objectives: To investigate the association between body mass index (BMI) or its changes and early-onset FOT development.
Methods: This nationwide population-based longitudinal cohort study included a cohort of 2,012,928 Korean children who underwent two consecutive health examinations at 30-36 months and 42-48 months of age between 2009 and 2020. The BMI and its changes derived during health screenings at 30-36 and 42-48 months. We performed multivariate Cox proportional hazards regression analyses to estimate the risk of early-onset FOT, including HS, AC, and DCS.
Results: During the follow-up, 1,283 FOT, including 143 HS, 1,068 AC, and 72 DCS, events were identified. Children with obesity were at an elevated risk of early-onset FOT compared to those with a normal weight (FOT: adjusted hazard ratio [aHR] 1.49, 95% confidence interval [CI] 1.21-1.84; HS: aHR 2.30, 95% CI 1.39-3.82; AC: aHR 1.36, 95% CI 1.07-1.73). BMI gain was correlated with an elevated risk of early-onset FOT, particularly HS, whereas BMI loss was linked to a decreased risk of early-onset FOT, especially HS. Children who became obese had an increased early-onset FOT risk (aHR 1.51, 95% CI 1.07-2.14) compared to those who maintained a normal weight. Children who reduced from obese to normal weight exhibited a decreased risk of early-onset FOT (FOT: aHR 0.41, 95% CI 0.17-0.96, P for trend=0.02; HS: P for trend=0.05) compared to obese children who retained their weight.
Conclusions: Childhood obesity was associated with an elevated risk of early-onset FOT, including HS and AC. Weight gain was correlated with an increased risk of early-onset FOT, especially HS, while weight loss was associated with a decreased risk of early-onset FOT, particularly HS. Implementing purposeful weight-reduction strategies may be helpful in preventing early-onset FOT development.
