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 7–15 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.
