Objective To investigate the prevalence and epidemiological characteristics of primary palmar hyperhidrosis (PPH) among adolescents in PR China. Methods A nationwide survey was performed, including all seven geological areas of Mainland China. Stratified cluster sampling was performed, and a cross-sectional epidemiological survey was applied via questionnaire among 10,000 college students in each geological area. Results The prevalence rate of PPH was 2.08?%. The prevalence in female adolescents was slightly higher than the prevalence in male adolescents (2.29 vs. 1.94?%). The prevalence of PPH in coastal areas was higher than the prevalence of PPH in inland areas (2.81 vs. 1.53?%). The peak age of onset is 7-5?years, accounting for 97.3?% of the PPH population. Positive family history was found in 25.40?% of PPH cases. In addition to palms, axillae and soles can also be affected. Conclusions PPH affects a larger group of individuals than previously reported. More measures should be taken to enhance the recognition, diagnosis, and treatment of PPH.
