Contemporary smoking habits among nurses in Mainland China

Although China is the world's largest consumer of tobacco and tobacco-related products, the epidemiology of smoking has not been well studied among nurses. Given this serious gap in the literature, we considered it necessary to investigate tobacco smoking habits among a large cross-section of contemporary Chinese nurses, by means of a questionnaire survey. A total of 509 replies were obtained from 520 nurses (response rate: 97.9%). The overall prevalence of smoking was 2.6% (95%CI 1.5 - 4.3). When stratified by gender, the prevalence rate among male nurses was 52.2% (33.0 - 70.8). Of those who smoked, the median number was 11 smokes per day for a period of 25.0 years. When categorized by severity, 15.4% were light smokers, 69.2% moderate smokers and 15.4% heavy smokers. When stratified by age there were no smokers under 25 years, with the prevalence between 25 and 34 years similarly low, at 1.1%. The highest smoking rate was seen among nurses aged 45 to 50 years (10.1%), even though they only comprised 9.8% of the total workforce. Although our study suggests that tobacco usage is relatively uncommon among Chinese nurses overall, the rate among male nurses was alarmingly high. The distribution of smoking by age was not uniform however, with a high proportion being concentrated in the older age ranges. As such, future preventive measures will need to consider the individual situation of Chinese nurses who smoke, particularly those who occupy the older age groups.
