Prevalence and associated factors of depressive symptoms among Chinese male correctional officers.

OBJECTIVES: Chinese correctional officers (COs) consist of frontline COs in direct contact with the prisoners and non-frontline COs (including administrative staff and professionals). Male COs compose the majority of Chinese COs, especially for frontline COs. Although they are quite susceptible to depressive symptoms due to highly risky and stressful working environment, few studies focus on this issue. This study aimed to evaluate the prevalence of depressive symptoms and to explore its associated factors among Chinese male frontline and non-frontline COs. METHODS: This cross-sectional study was performed during the period of March/April 2011. The study population comprised of 1,900 male COs in four male prisons in a province of northeast China. A questionnaire including the Center for Epidemiological Studies Depression Scale, demographic factors, work conditions, effort-reward imbalance questionnaire was distributed to these COs. A total of 1,494 effective respondents became our subjects (981 frontline COs and 513 non-frontline COs). Frontline and non-frontline COs were analyzed separately. RESULTS: Approximately 61.4% of Chinese male COs had depressive symptoms (63.5% in frontline COs and 57.3% in non-frontline COs). Multivariate logistic analyses showed that effort-reward ratio, overcommitment, chronic disease, and threat perception were associated with depressive symptoms in frontline and non-frontline COs, whereas weekly work time had an effect only in frontline COs. CONCLUSIONS: Chinese male COs, especially frontline COs, might have high-level prevalence of depressive symptoms. Moreover, this study had identified important risk factors that might be important in planning strategies for prevention and intervention of depressive symptoms for Chinese male COs.

The prevalence of depression and anxiety among Chinese adults with cancer: a systematic review and meta-analysis.

BACKGROUND: A lot of empirical studies have been conducted to evaluate the prevalence of depression and anxiety among Chinese adults with cancer. We aimed to conduct a meta-analysis in order to evaluate the prevalence and odds ratios of depression and anxiety in Chinese adults with cancer compared with those without. METHODS: The three most comprehensive computerized Chinese academic databases-CNKI, Wangfang and Vip databases-were systematically screened through September 2012. PubMed and Web of Science (SCIE) were also searched from their inception until September 2012 without language restrictions, and an internet search was also used. Case-control studies assessing the prevalence of depression and anxiety among Chinese adults with cancer were analyzed. Study selection and appraisal were conducted independently by three authors. The non-weighted prevalence, pooled random-effects estimates of odds ratio (OR) and 95% confidence intervals (CI) were all calculated. RESULTS: Seventeen eligible studies with a total of 3497 subjects were included. The prevalence of depression and anxiety were significantly higher in adults with cancer compared with those without (Depression: 54.90% vs. 17.50%, OR = 7.85, 95% CI = 5.56-11.07, P = 0.000; Anxiety: 49.69% vs. 18.37%, OR = 6.46, 95% CI = 4.36-9.55, P = 0.000), the same situation was also observed in subgroup of control groups, assessment methods and cancer types. Although no difference of depression was observed in studies utilizing clinical diagnosis compared with self-report, the OR of anxiety in adults with cancer compared with those without was higher in studies utilizing clinical diagnosis (OR = 8.42, 95% CI = 4.83-14.70) than self-reports (OR = 5.83, 95% CI = 3.64-9.34). The ORs of depression and anxiety in cancer patients compared with disease group (Depression: OR = 6.03, 95% CI = 4.23-8.61; Anxiety: OR = 4.40, 95% CI = 3.05-6.36) were lower than in those compared with normal group (Depression: OR = 13.58, 95% CI = 6.26-29.46; Anxiety: OR = 15.47, 95% CI = 10.00-23.95). CONCLUSIONS: We identified high prevalence rates of depression and anxiety among Chinese adults with cancer. The findings support that the prevalence of depression and anxiety among adults with cancer should receive more attention in Chinese medical settings.
