To analyze the relationship between nicotine dependence and depression among the elderly of Dai ethnic group in Jinggu county, Yunnan Province.
By using the method of multi-stage stratified random sampling,1 409 rural Dai people aged 60 and over in Jinggu county, Yunnan Province were investigated by face-to-face questionnaire.
The current smoking rate of rural Dai elderly in Jinggu county, Yunnan Province was 18.6% (37.1% for males and 0.8% for females). The smoking rate of males was significantly higher than that of females (P < 0.01). At present, the nicotine dependence rate of smokers was 32.8% (32.4% for males and 50.0% for females). There was no significant difference in nicotine dependence among Dai elderly people of different genders (P > 0.05), age groups (P > 0.05), education (P > 0.05), and annual family per capita income (P > 0.05). The prevalence rate of depression in the surveyed population was 52.0% (49.4% for males and 54.5% for females). Multivariate Logistic regression model analysis showed that patients with nicotine dependence were more likely to suffer from depression than those without nicotine dependence (OR=1.517, 95%CI: 1.066-2.158).
Nicotine dependence is positively correlated with depression in the elderly of Dai ethnic group in Yunnan Province. Taking effective measures to reduce the nicotine dependence rate of smokers is helpful to improve the mental health level of the elderly.
