Depression symptoms and chronic pain in the community population in Beijing, China.

We explore the association of depressive symptoms and chronic pain (arthritis, back or neck pain, headache, or other pain) in a community population of Beijing, China. Two thousand four hundred and sixty nine residents aged 16 years and older were investigated in 2010. Data were collected from face-to-face interviews using the Composite International Diagnostic Interview-3rd version. The presence of chronic pain condition and depressive symptoms were analyzed using univariate and multivariate analysis methods. We found a 12-month prevalence of MDD (Major depressive disorder) at 3.28%. Nearly half (41.01%) of respondents with depressive symptoms also had at least one chronic pain condition, and 64.20% of subjects with MDD (Major depressive disorder) experienced at least one chronic pain. After adjusting for selected demographic variables, it was found by multivariate logistic regression analysis that depressive symptom without MDD was significantly associated with back-or neck pain (Adjusted odds ratio (AOR)=1.97, 95% CI, 1.34-2.90), headache (AOR=3.17, 95% CI, 1.81-5.58), and other chronic pain (AOR=2.21, 95% CI, 1.07-4.49). MDD was significantly associated with arthritis (AOR=2.23) back or neck pain (AOR=4.17), headache (AOR=3.16), and other chronic pain (AOR=3.51). Multiple types of chronic pain are associated with depressive symptoms and MDD. Future studies are needed to infer causality.

Disability associated with mental disorders in metropolitan China: an application of the quantile regression approach.

Recently active mental disorders are associated with substantial disability, but there is little research on residual disability once symptoms have subsided. The aim of this study is to estimate the degree to which recent disability might be due to recent or past history of mental disorders using a quantile regressions (QR) model that makes it possible to study the full range of disability. Data were from cross-sectional surveys of Chinese living in Beijing and Shanghai, China (n=1628). The World Health Organization Disability Assessment Schedule and the WHO Composite International Diagnostic Interview were used to assess recent disability and common mental disorders, respectively. Recently active mental disorders are found to be associated with elevated levels of disability, especially for current substance use disorder. Anxiety disorders stand out with high levels of disability. Individuals at the higher disability levels show large variations in their disability levels. These epidemiological estimates from China add to the evidence based on the global burden of neuropsychiatric disorders, quantifying the hypothesized influence of recently active and past disorders with the novel QR approach. In future studies, we hope to complete more detailed studies of the causal role of mental disorders in the development of disability.

Associations linking parenting styles and offspring personality disorder are moderated by parental personality disorder, evidence from China.

The aim of the study is to examine the association linking parenting and personality disorder controlling for parental personality disorder, and whether this association is moderated by parental PD. Data were from community-dwelling high school students aged 18 and above and their parents living in Beijing, China. A total of 181 cases and 2,605 controls were included in this study. Personality disorder in students was assessed via a two-stage approach, Personality Diagnostic Questionnaire as a screening tool and International Personality Disorder Examination as the diagnostic tool. Information about parenting was collected from students using Egna Minnen av. Betraffande Uppfostran. Negative parenting styles, e.g. rejective or over-protective parenting, were found to be associated with the occurrence of personality disorder. Conflictive parenting styles were also found to be associated with personality disorder. Generally stronger associations were found for students with parental personality disorder as compared to students without parental personality disorder. Findings from this study support the role of parenting in the occurrence of PD, especially for children with family history of personality disorder.
