Abstract
Objective
This study investigated the sex-specific prevalence of smoking (past 30 days) and the associations with height among university/college students.
Participants
25,405 (11,579/14,826 males/females) college students in Xi’an China.
Methods
A cross-sectional, self-administered survey.
Results
The male and female prevalence of smoking (past 30 days) was 32.9% and 7.4%, respectively. The prevalence of smoking of the male height groups ranged from 29.8% to 36.9%; only the ≥188 cm height group showed significantly higher prevalence than the reference group (i.e., 173–177cm; 33.0%). The female prevalence of smoking was 4.0–8.2% in the ≤170cm groups and increased to 12.3% in the 171–175 cm group and 36.1% in the ≥176 cm group, while it was 6.5% for the reference group (161–165 cm).
Conclusions
This exploratory study firstly revealed the significantly higher prevalence of smoking among the “tallest” height groups, especially among females. Future studies are warranted to confirm such findings and explore related mechanisms.
