Objective To investigate the prevalence and correlates of depression in residents aged 15 and older in Hainan province.Methods Stratified multistage random sampling methods were utilized to identify 12 117 individuals (≥15 years old) from 59 villages (neighborhoods) in 24 towns (streets) within 6 counties (cities) in Hainan Province from September 2010 to November 2011.The subjects were screened with an expanded version of the General Health Questionnaire (GHQ-12) and the respondents were divided into three groups by high risk,moderate risk and low risk of mental disorder,followed by formal diagnosis according to the Structured Clinical Interview for DSM-IV-TR (SCID-I/P) by psychiatrists among 100％ subjects in group with high risk,40％ subjects in group with moderate risk and 10％ subjects in group with low risk.The adjusted rate,standardized rate,and 95％ confidence interval (95％CI) of the one-month and lifetime prevalence were also calculated among the 3 groups of individuals who were diagnosed with depressive disorder.The difference in whether they suffered depression was determined by the chi-squared test.Correlations to depressive disorder and the odds ratio (OR) were explored with multiple regression analysis.Results There were 97 cases of depressive disorders (1-month) and 166 cases of lifetime depressive disorders finally confirmed.The adjusted rate of 1-month prevalence was 1.38％ (95％CI:1.12-1.59) and the life-time adjusted prevalence rate was 2.80％ (95％CI:2.51-3.09).Female (OR=1.55,95％CI:1.12-2.14),mid-age(50-64 y,OR=1.84,95％CI:1.13-2.99),being divorced or living separated (OR=4.87,95％CI:1.86-12.73),suffering chronic diseases (OR=2.19,95％CI:1.56-3.07),and low family income were significantly associated with suffering depressive disorder.Conclusions The prevalence of the depressive disorder among residents aged 15 and older in Hainan province is lower than the nationwide prevalence.People who are female,mid-age,being divorced or not living with the partner,earning a low income,and suffering chronic diseases have more predisposition to develop the depressive disorder in Hainan province.

Objective To observe the effect of acupoint thread-embedding at Neiguan (PC6) and Zusanli (ST36) on anxiety and sleep disorders after heroin withdrawal. Method Sixty-seven patients with heroin addiction were randomized into a Neiguan group (25 cases), a Zusanli group (22 cases) and a Neiguan plus Zusanli group (20 cases), to receive corresponding treatments once every 20 d, for 4 sessions in total. The Self-rating Anxiety Scale (SAS) and Pittsburgh Sleep Quality Index (PSQI) were adopted to observe the anxiety and sleep condition before and after the treatment. Result After 60 d thread-embedding treatment, the total and standard SAS scores, sleep initiation time and total PSQI score were significantly decreased in the 3 groups (P<0.05), and the sleep durations were significantly extended (P<0.05); in comparing the improvement of anxiety, Neiguan plus Zusanli group > Neiguan group >Zusanli group (P<0.05); in comparing the improvement of sleep, Neiguan plus Zusanli group was superior to both Zusanli group and Neiguan group (P<0.05), while there was no significant difference between Zusanli group and Neiguan group (P>0.05). Conclusion It's effective to use thread-embedding at Neiguan and Zusanli independently or together for anxiety and sleep disorders after heroin withdrawal, but the efficacy is more significant when the two points are used in combination, indicating the synergy of acupoints.
