AB  - BACKGROUND: As a crucial component of solar radiation, the association between 
      exposure to ambient ultraviolet (UV) radiation and acne remains unclear. METHODS: 
      This was a multicenter retrospective cohort study of incoming college students in 
      five universities of China. Previous exposure (6 years prior to enrollment) to 
      different wavelengths of ambient UVs were obtained from public repositories by 
      linking to individual hometown addresses. Logistic models were applied to assess 
      the relationship between ambient UV exposure and acne. Subgroup analysis was 
      conducted by sun protection behaviors and time of daily sun exposure. Overall 
      effect and single effect of exposure to four different wavelengths of UVs (305, 
      310, 324, and 380 nm) were estimated by Bayesian kernel machine regression 
      (BKMR). RESULTS: A total of 19,939 participants was included for analysis. 
      Analysis in all participants showed a significant association between 
      log-transformation levels of exposure to UV at 305 nm (log (UV 305 nm)) and acne 
      (OR = 0.77, p = .021). The effect size was stronger in participants reporting no 
      sun protection habit. Both UVs at 305 nm (OR = 0.51, p = .001) and 310 nm 
      (OR = 0.50, p = .012) were associated a decreased risk of acne in participants 
      reporting no sun protection habit. This inverse association was also observed in 
      those exposed to low levels of UV (<1 h/day). The BKMR indicated consistent 
      results that low levels of exposure to UVs combination and UVs at 305 and 310 nm 
      were associated with a lower risk of acne. CONCLUSION: Long-term exposure to 
      relatively low levels of ambient UVB are associated with a decreased risk of 
      moderate-to-severe acne in college students.
