Objective: Poor mental health is associated with impaired social functioning, lower quality of life, and increased risk of suicide and mortality. This study examined the prevalence of poor general mental health among older adults (aged 65 years and above) and its sociodemographic correlates in Hebei province, which is a predominantly agricultural area of China. Methods: This epidemiological survey was conducted from April to August 2016. General mental health status was assessed using the 12-item General Health Questionnaire (GHQ-12). Results: A total of 3,911 participants were included. The prevalence of poor mental health (defined as GHQ-12 total score ≥ 4) was 9.31% [95% confidence interval (CI): 8.4–10.2%]. Multivariable logistic regression analyses found that female gender [ P < 0.001, odds ratio (OR) = 1.63, 95% CI: 1.29–2.07], lower education level (P = 0.048, OR = 1.33, 95% CI: 1.00–1.75), lower annual household income (P = 0.005, OR = 1.72, 95% CI: 1.17–2.51), presence of major medical conditions (P < 0.001, OR = 2.95, 95% CI: 2.19–3.96) and family history of psychiatric disorders (P < 0.001, OR = 3.53, 95% CI: 2.02–6.17) were significantly associated with poor mental health. Conclusion: The prevalence of poor mental health among older adults in a predominantly agricultural area was lower than findings from many other countries and areas in China. However, continued surveillance of mental health status among older adults in China is still needed. [ABSTRACT FROM AUTHOR]

Background: Major depressive disorder (MDD) is common among older adults. The epidemiology of MDD is greatly influenced by sociocultural and economic factors. This study examined the 1-month and lifetime prevalence of MDD and its socio-demographic correlates in older adults living in Hebei province, an agricultural area of China.Methods: Multistage, stratified, random sampling was administered between April and August 2016. The diagnosis of MDD was established with the Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders fourth edition (DSM-IV) Axis I Disorders.Results: A total of 3911 participants were enrolled. The 1-month and lifetime prevalence of MDD in older adults was 2.0% (95%CI: 1.6-2.4%) and 3.4% (95%CI: 2.8-4.0%), respectively. Multivariable logistic regression analyses revealed that female gender [P < 0.001, adjusted odds ratio (aOR) = 2.6, 95%CI: 1.53-4.53], presence of comorbid major medical conditions (P < 0.001, aOR = 4.8, 95%CI: 2.17-10.39) and family history of psychiatric disorders (P = 0.013, aOR = 3.4, 95%CI: 1.30-8.96) were independently and significantly associated with higher odds of MDD.Conclusion: The prevalence of MDD in older adults in Hebei province, China, was lower than most findings in China and other countries. Nevertheless, continued surveillance of elderly depression in China along with the development of primary, secondary and tertiary preventative interventions for the elderly with MDD is indicated.

Background: Major depressive disorder (MDD) is a common psychiatric disorder which is associated with significant disability and psychosocial factors. There are only few epidemiological studies of MDD in economically underdeveloped regions of China. This study examined the 1-month and lifetime prevalence of MDD and their sociodemographic correlates in Hebei province, China.Methods: Using multistage, stratified and random sampling, the study was conducted between April and August 2016. The diagnosis of MDD was established using the Structured Clinical Interview for DSM-IV Axis I Disorders-Patient Edition.Results: The weighted 1-month and lifetime prevalence of MDD were 0.9% (95%CI: 0.8-1.1%) and 1.6% (95%CI: 1.4-1.8%), respectively in the sample of 14,654 adult participants. Multiple logistic regression analysis revealed that the age group of 45-59 years (P < 0.001, OR=3.206, 95%CI:1.693-6.072), female gender (P < 0.001, OR=2.171, 95%CI: 1.522-3.097), married marital status (P < 0.001, OR=0.328, 95%CI: 0.198-0.545), college educational level or higher (P = 0.006, OR=0.145, 95%CI: 0.037-0.573), employment (P = 0.010, OR=2.305, 95%CI: 1.220-4.353), major medical conditions (P < 0.001, OR=3.758, 95%CI: 2.607-5.418) and family history of psychiatric disorders (P < 0.001, OR=3.947, 95%CI: 2.203-7.071) were significantly associated with MDD.Conclusion: The prevalence of MDD in Hebei province was found to be lower than in most areas of China and other countries. Further studies are warranted to confirm the low prevalence of MDD in other economically underdeveloped regions of China. [ABSTRACT FROM AUTHOR]
