Objective: To examine the association between parent-child communication frequency about school related matters and depressive symptom risk among children and adolescents and to characterize its dose response pattern, so as to provide a reference for family intervention and school mental health promotion. Methods: Data were obtained from the 2022 China Family Panel Studies(CFPS), conducted from May to December 2022. A total of 1 896 children and adolescents aged 10-15 years were included. The 8 item Center for Epidemiologic Studies Depression Scale (CES-D8) was adopted to assess depressive symptoms among children and adolescents. Data on the parent-child communication frequency about school related matters was obtained from CFPS Child Proxy Questionnaire. Multivariable Logistic regression, sensitivity analyses, and exploratory segmented regression were performed. Results: A total of 375 participants were screened positive for depressive symptoms, with a prevalence of 19.8%. The prevalence decreased from 23.3% in the "never" group to 10.6% in the "very often" group ( χ 2=19.30, P <0.05). In the fully adjusted model, the point estimate for the "very often" group suggested lower odds of a positive screen ( OR =0.52), and the test for trend was statistically significant ( P =0.03). The association was more pronounced among children aged 10-12 years ( OR=0.31, 95%CI=0.11-0.86, P <0.05). Sensitivity analyses yielded directionally consistent results, but the statistical evidence was weakened ( OR=0.83, P trend =0.08). Dose response analysis showed a statistically significant overall association between parent-child communication frequency about school related matters and depressive symptom risk ( P =0.04), with no significant departure from linearity ( P = 0.14 ). Among the prespecified cut points, exploratory segmented regression showed relatively better model fit at an ordinal frequency score of 4.5, between "often" and "very often" (likelihood ratio test P =0.03). However, the overall test for nonlinearity was not statistically significant ( P =0.14), and the finding should therefore be interpreted as exploratory. Conclusion More frequent parent-child communication about school related matters is associated with lower depressive symptom risk, suggesting that routine communication about such matters may help reduce the risk of depressive symptoms in children and adolescents.

Objective To observe the effect of 3R therapy on quality of life and subjective well-being in older patients with mild cognitive impairment (MCI). Methods 158 patients with MCI were collected from 8 communities in Ningbo city with Diagnostic and Statistical Manual of Mental Disorders (DSM)-IV as the diagnostic criteria, and assessed by Montreal Cognitive Assessment (MoCA). The experimental group (n=79) was intervened by 3R (Reminiscence, Reality Orientation, Remotivation) for 12 weeks, and the control group (n=79) received no intervention. Their quality of life was assessed with WHO Quality of Life-BREF (WHOQOL-BREF) and the subjective well-being was assessed with Philadelphia Geriatric Center Morale Scale (PGC). Results Their quality of life and subjective well-being improved after intervention in the experimental group (P<0.05), and were better in the experimental group than in the control group (P<0.05). Conclusion 3R therapy could effectively improve the quality of life and subjective well-being in patients with MCI.

Objective To investigate the factors of lifestyle associated with the mild cognitive impairment (MCI). Methods A 1∶ 2 matched case-control study investigated 120 patients of MCI and 240 healthy controls with lifestyle factors associated with MCI. Results Multiple factors analysis confirmed that, participate in social activities (OR=0.562, 95%CI: 0.359~0.723), playing chess or joke (OR=0.603,95%CI: 0.323~0.884), travelling (OR=0.683, 95%CI: 0.467~0.912), continue to work after retirement (OR=0.531, 95%CI: 0. .326~0.724),reading (OR=0.272, 95%CI: 0.174~0.428), using computer (OR=0.536, 95%CI: 0.427~0.869), regular physical exercise (OR=0.437, 95% CI: 0.316~0.732), friendship (OR=0.583, 95%CI: 0.385~0.765), meeting children (OR=0.464, 95%CI: 0.316~0.745), intaking unsaturated fatty acids (OR=0.524, 95%CI: 0.368~0.787), often eating fish and seafood (OR=0.224, 95%CI: 0.171~0.383), daily consumption of fruits and vegetables (OR=0.485, 95%CI: 0.316~0.665) were protective factors for MCI. Conclusion A positive, leisure lifestyle, health reasonable diet and avoiding risk factors could effectively reduce the risk of MCI.
