Effects of Social Support on Medication Adherence Among Patients with Schizophrenia: Serial Multiple Mediation Model.

Purpose: This study aims to explore the serial mediating effect of stigma and depression on the association between social support and medication adherence. Patients and Methods: A cross-sectional survey was undertaken in the Changning District of Shanghai using a five-part questionnaire from August to December 2023. A convenient sampling method was employed, and 35 patients with schizophrenia were invited from each of the 9 streets in Changning District to participate in the survey, resulting in a total of 305 valid questionnaires collected. The questionnaire measured social support, stigma, depression, medication adherence, and demographic characteristics. Data analysis involved descriptive statistics, independent samples t-tests, ANOVA, Pearson correlation analysis, and the bootstrap method. Results: There was a direct and significantly positive association between social support and medication adherence (ß = 0.69, p < 0.001). Moreover, increased levels of stigma (ß = - 0.45, p = 0.013) and depression (ß = - 0.09, p = 0.017) were both associated with a decline in medication adherence. Bootstrapping analysis revealed that the association between social support and medication adherence operated indirectly through stigma (ß = 0.11, 95% CI: 0.03, 0.18). Additionally, social support was indirectly associated with medication adherence through depression (ß = 0.15, 95% CI: 0.04, 0.30). Further analysis indicated that social support had an indirect association with medication adherence through both stigma and depression (ß = 0.04, 95% CI: 0.01, 0.07). Conclusion: Stigma and depression serially mediate the association between social support and medication adherence among patients with schizophrenia. This serial multiple mediation model underscores the importance of integrating social support interventions with psychological interventions aimed at reducing stigma and depression, thereby effectively enhancing medication adherence in patients with schizophrenia.

Association of maternal mineral status with the risk of preterm birth: a retrospective cohort study.

Background: There has been a gradual increase in the proportion of preterm birth in China during the past several decades. Maternal malnutrition is a significant determinant for preterm birth. Nevertheless, comprehensive studies investigating serum mineral levels during pregnancy associated with preterm birth remain scarce. This study aims to assess the associations between maternal serum mineral levels and the risk of preterm birth. Methods: This retrospective cohort study of 18,048 pregnant women used data from a tertiary hospital in China from January 2016 to December 2022. Demographic data and serum mineral concentrations in the second and third trimesters of mothers were collected from the hospital information system. Analysis was performed using restricted cubic splines and logistic regression models. Results: The proportion of preterm birth in this study was 6.01%. Phosphorus [P for overall = 0.005; P for nonlinear = 0.490; OR (95%CI) = 1.11 (1.04, 1.18)] and chlorine [P for overall = 0.002; P for nonlinear = 0.058; OR (95%CI) = 1.11 (1.03, 1.19)] showed a significant positive correlation with preterm birth in a linear fashion. Furthermore, serum levels of potassium (P for nonlinear <0.001), sodium (P for nonlinear = 0.004), and magnesium (P for nonlinear <0.001) exhibited non-linear relationships with the risk of preterm birth. Conclusion: Serum levels of some minerals during pregnancy were associated with the risk of preterm birth among pregnant women. In addition to commonly recognized micronutrients such as folic acid, iron, and vitamin D, healthcare providers should also pay attention to the levels of these minerals during pregnancy.

The effect of perceived social support and health literacy on parental COVID-19 vaccine hesitation in preschool children: a cross-sectional study.

Children are generally susceptible to COVID-19, and infection with COVID-19 may cause serious harm to children. COVID-19 vaccination is an effective way to prevent infection at present, and many factors affect children's COVID-19 vaccination. This study aimed to explore the effects of perceived social support and health literacy on hesitancy towards first and second vaccine dose. This cross-sectional study was conducted in the Minhang District of Shanghai, China, in October 2022. A total of 1150 parents of preschool children from 10 kindergartens participated. The survey encompassed four sections, capturing data on sociodemographic attributes, health literacy, perceived social support, and parental COVID-19 vaccine hesitancy. Health literacy was measured using a self-designed questionnaire consisting of four dimensions. Perceived social support was assessed using the MSPSS questionnaire. Hierarchical multiple logistic regression was used to examine the relationship between the independent variables and parental hesitancy towards the first and second doses of COVID-19 vaccine. Parental hesitancy rate for the first dose of the COVID-19 vaccine was 69.6%, and for the second dose, it was 33.1%. The final integrated model showed that parental hesitancy towards the first and the second dose of COVID-19 vaccine was associated with parental educational level, allergy in children, information decision-making and information comprehension ability, perceived social support from family and friends. Health literacy and perceived social support are influence factors for parental hesitancy towards COVID-19 vaccine for preschool children. The findings will provide insights for future intervention studies on COVID-19 vaccine hesitancy and inform the development of vaccination policies.

The effect of anxiety, depression, and structural social capital on life satisfaction among people with hearing disabilities: a cross-sectional study in Shanghai, China.

Background: Life satisfaction (LS) serves as a crucial indicator of social wellbeing and plays a significant role in formulating strategies aimed at enhancing health outcomes among the hearing-disabled population. This study aimed to examine the effect of anxiety, depression, and structural social capital on life satisfaction among people with hearing disabilities in Shanghai, China. Methods: A cross-sectional study was conducted in Shanghai, China. As of March 2022, 337 people with hearing disabilities were recruited from the Shanghai Disabled Persons' Federation. An online survey was conducted using a four-part questionnaire to collect data including demographic characteristics, the Hospital Anxiety and Depression Scale (HADS), the Social Capital Scale (SCS), and a single-item question to measure life satisfaction. One-sample t-tests, Pearson's correlation analysis, and hierarchical multiple regression analysis were performed. Results: Anxiety (ß = - 0.153) and depression (ß = - 0.242) were significant factors influencing life satisfaction among people with hearing disabilities. Structural social capital also played an influential role in life satisfaction, and people with hearing disabilities who lack social networks (ß = 0.125) and social support (ß = 0.121) reported significantly lower levels of life satisfaction. However, no significant relationship was found in this study between LS and other components of structural social capital, such as social participation. Conclusion: This study shows that paying attention to mental health is critical for people with hearing disabilities to achieve social wellbeing and promote LS improvement. At the same time, the government and society also need to focus on the structural social capital, provide various social service programs, enhance social support, and expand social networks, improving LS for people with hearing disabilities.

Parents' intention to vaccinate their preschool children against COVID-19: Combining the health belief model and the theory of planned behavior.

The vaccination rate of COVID-19 in preschool children is low, and parents' intention to vaccinate their children is also low due to multiple factors. This study aimed to establish an integrated model based on the Health Belief Model (HBM)and Theory of Planned Behavior (TPB), to explore the factors influencing parents' intention to vaccinate their preschool children with the first and second doses of COVID-19 vaccines. A total of 1264 parents of preschool children from 10 kindergartens participated in this study. Hierarchical multiple logistic regression was used to analyze the intention separately. For the integrated model with the first dose of vaccine of COVID-19, introducing the HBM variable in model 1 explained 33.98% of the variance (F = 398.71, p < .001), then upon adding the TPB variable in model 2, the explanation of variance increased to 41.93% (F = 491.94, p < .001) and parents' intention were associated with their perceived barriers, cues to action, and subjective norms. For the integrated model with the second dose of vaccine of COVID-19, introducing the HBM variable in Model 1 explained 23.76% of the variance (F = 68.82, p < .001), then upon adding the TPB variable in model 2, the explanation of variance increased to 26.67% (F = 77.24, p < .001), and parents' intention was associated with cues to action and subjective norms. The combination of the two theories improves the explanatory power of parents' intention to vaccinate their preschool children against COVID-19, and provides a basis for the development of effective interventions for vaccination of COVID-19 for preschool children.

Effects of social support on oral health behavior: Serial multiple-mediator model.

OBJECTIVE: This study investigates the serial multiple mediation of job stress and perceived behavioral control (PBC) in the relationship between social support and oral health behavior (OHB). MATERIALS AND METHODS: This cross-sectional study was conducted in Minhang District, Shanghai, China, between July and November 2021. 559 Employees from 10 community health centers were recruited. A five-part survey was used to collect data on demographic characteristics, social support, job stress, PBC and OHB. Descriptive statistics, independent-sample t-test, Pearson's correlation analysis, ordinary least-squares regression and the bootstrap method were used to analyze data. RESULTS: Social support was found to impact OHB through three significant mediation pathways: the pathway through job stress (point estimate = 0.033; 95%BC CI [0.004, 0.089]), the pathway through PBC (point estimate = 0.283; 95%BC CI [0.174, 0.416]), and the serial multiple mediating pathway through first job stress and then PBC (point estimate = 0.006; 95%BC CI [0.001, 0.019]). CONCLUSION: This study indicates that job stress and PBC play a serial multiple-mediator role in the relationship between social support and OHB. To ensure the effectiveness of social support intervention on OHB, workplace managers and employees should strengthen the motivators that could promote the reduction of job stress and the improvement of PBC.

Effects of Stigma on the Relationship Between Perceived Social Support and Sexual Satisfaction Among Breast Cancer Survivors.

BACKGROUND: Sexual satisfaction is one of the issues faced by breast cancer survivors (BCSs). AIM: This study aims to explore the mediation of stigma in the relationship between perceived social support (PSS) and sexual satisfaction among breast cancer survivors. METHODS: A cross-sectional study was conducted among 918 BCSs in Shanghai Cancer Rehabilitation Club. Data were collected using an online questionnaire including questions on sociodemographic characteristics, health status, PSS, stigma and sexual satisfaction of participants. The bootstrap method was used to test the significance of the simple mediation model. OUTCOMES: The simple mediation of stigma was found significant in the relationship between PSS and sexual satisfaction. RESULTS: Stigma plays an intermediary role in the relationship between 2 dimensions of PSS (family and friends) and sexual satisfaction, but not in the relationship between the dimension of other significant people of PSS and sexual satisfaction. CLINICAL TRANSLATION: It is important to reduce stigma when improving the sexual satisfaction of BCSs from the perspective of PSS. STRENGTHS & LIMITATIONS: The mediating role of stigma in the relationship between PSS and sexual satisfaction among BCSs has been shown for the first time. Study limitations include limitations in the representativeness of population by the study sample and the cross-sectional study design. CONCLUSIONS: Stigma mediates the relationship between PSS and sexual satisfaction, which needs to be eliminated in intervention practice. Yuxin Zhang, Jie Zhao, Nan Jiang, et al.
