This study examined the moderating role of perceived community belonging in the relationship between childhood abuse and health and well-being outcomes among Canadian individuals aged 55 and older. Using data from the 2014 Canadian General Social Survey (n = 14,416), multiple linear regression models revealed that women who experienced either childhood physical or sexual abuse reported poorer self-rated general and mental health, as well as lower life satisfaction, compared to those without such histories. The most pronounced effects were observed among women who experienced both types of abuse. For men, a similar pattern was evident only for those who experienced childhood physical abuse. Notably, among women, a strong sense of community belonging lessened the negative effects of both types of childhood abuse on all examined outcomes. These findings underscore the protective role of perceived community belonging against the consequences of childhood abuse for older women. They illuminate the crucial role of gerontological social workers and scholars in promoting community integration and support. Focusing on these areas, especially for those with traumatic histories, can potentially improve their overall health and well-being. [ABSTRACT FROM AUTHOR]

Despite growing interest in the health disparities associated with food insecurity, research focusing on Indigenous peoples has been limited, especially in studies using nationally representative samples. This study investigates the association between food insecurity and various health outcomes – self-rated general and mental health, chronic health conditions, suicidal ideation, and obesity – among Indigenous peoples in Canada. It also explores the potential moderating effects of culture-based resources, which include cultural identity affect, cultural group belonging, cultural engagement, and cultural exploration. The study utilized data from the 2017 Aboriginal Peoples Survey, a nationally representative sample of First Nations individuals living off-reserve, Métis, and Inuit across Canada (N = 15 ,533). Logistic regression models were used to analyze the data. Food insecurity was negatively associated with all examined health outcomes. Culture-based resources demonstrated a mixture of anticipated and unexpected effects on these relationships. Consistent with the stress process model, cultural group belonging mitigated the negative impact of food insecurity on all health outcomes. A similar pattern was observed for cultural engagement. However, contrary to expectations from the stress-buffering perspective, little evidence was found to support the moderating effects of cultural identity affect and cultural exploration. The results underscore the detrimental effects of food insecurity on the health of Indigenous peoples in Canada and suggest that culture-based resources, particularly cultural group belonging, play a crucial role in mitigating health disparities.

This study examines the associations between sleep quality and internalizing and externalizing problems among Chinese adolescents and investigates whether academic performance and self-esteem function as mediators. Data were obtained from the 2018 wave of the China Family Panel Studies (CFPS), comprising a sample of 1,016 Chinese adolescents aged between 10 and 15 years. We employed multiple mediation models, using Hayes' PROCESS macro, for data analysis. The results showed that poor sleep quality was associated with an increase in both internalizing and externalizing problems. Furthermore, academic performance and self-esteem were identified as mediators in these relationships, operating in parallel and sequential manners. Besides maintaining adequate sleep hours, interventions aimed at improving academic performance and self-esteem could potentially alleviate the adverse effects of poor sleep quality on internalizing and externalizing problems among adolescents.

This study investigates the association between financial strain and psychological distress among middle-aged and older adults, exploring how this association is mediated by sleep problems and moderated by marital status. A subsample of 12,095 adults aged 50 and older was selected from the 2018 National Health Interview Survey. Results showed that financial strain was associated with higher psychological distress, and sleep problems partially mediated this association. Marital status moderated the association between sleep problems and psychological distress, and between financial strain and psychological distress, but not between financial strain and sleep problems. These findings partially support the stress-buffering role of marriage. The study offers valuable insights into the complex relationship between financial strain, sleep problems, marital status, and psychological distress among middle-aged and older adults in the United States, highlighting the need for interventions targeting financial stressors and sleep problems, especially for unmarried individuals, to improve mental health outcomes in this population.

The present study examines (1) whether perceived life stress mediates the associations between length of residence in Canada and self-rated mental health and general health and (2) how these processes differ across levels of perceived local community belonging. Data are from the 2017–2018 Canadian Community Health Survey (N = 14,570)—a nationally representative survey collected by Statistics Canada. Simple mediation and moderated mediation models are employed. The simple mediated associations are evaluated first and found to be statistically significant for both self-rated mental health (b = 0.046, 95% PBCI = 0.035, 0.058) and general health (b = 0.045, 95% PBCI = 0.034, 0.056). Moderated mediation analysis then reveals that while perceived local community belonging does not moderate the effects of length of residence on perceived life stress, it does moderate the effects of perceived life stress on self-rated mental health (b = − 0.042, 95% PBCI = − 0.057, − 0.028) and general health (b = − 0.026, 95% PBCI = − 0.042, − 0.011), suggesting that the adverse associations between perceived life stress and self-rated mental health and general health are weaker among immigrants with greater perceived local community belonging. Consistent with the predictions, the indirect effects are significant at all levels of local community belonging. Findings from this study highlight the need to focus more research and policy interventions on community-based coping resources. [ABSTRACT FROM AUTHOR]

The accuracy of computed tomography angiography (CTA) image interpretation depends on the radiologist. This study aims to develop a new method for automatically detecting intracranial aneurysms from CTA images using deep learning, based on a convolutional neural network (CNN) implemented on the DeepMedic platform. Ninety CTA scans of patients with intracranial aneurysms are collected and divided into two datasets: training (80 subjects) and test (10 subjects) datasets. Subsequently, a deep learning architecture with a three-dimensional (3D) CNN model is implemented on the DeepMedic platform for the automatic segmentation and detection of intracranial aneurysms from the CTA images. The samples in the training dataset are used to train the CNN model, and those in the test dataset are used to assess the performance of the established system. Sensitivity, positive predictive value (PPV), and false positives are evaluated. The overall sensitivity and PPV of this system for detecting intracranial aneurysms from CTA images are 92.3% and 100%, respectively, and the segmentation sensitivity is 92.3%. The performance of the system in the detection of intracranial aneurysms is closely related to their size. The detection sensitivity for small intracranial aneurysms (≤ 3 mm) is 66.7%, whereas the sensitivity of detection for large (> 10 mm) and medium-sized (3–10 mm) intracranial aneurysms is 100%. The deep learning architecture with a 3D CNN model on the DeepMedic platform can reliably segment and detect intracranial aneurysms from CTA images with high sensitivity. [ABSTRACT FROM AUTHOR]

While prior research has well-documented the detrimental effect of cyberbullying victimization on health and well-being among children and adolescents, less is known about whether the same adverse pattern can be observed among adults. Moreover, it is unclear about what psychosocial resources might moderate this association. The present study uses a nationally representative cross-sectional survey—2014 Canadian General Social Survey (N = 17,548)—to examine three research questions. First, is cyberbullying victimization associated with adults' self-rated health, mental health, and life satisfaction? Second, how does religiosity—religious service attendance and religious beliefs—moderate this association? Third, do any observed patterns further differ for men and women? Through a series of logistic and ordinary least squares regression models, the results show that adults who experienced cyberbullying victimization in the past 5 years are more likely to report poor self-rated health and mental health compared to those who did not experience cyberbullying victimization in the past 5 years. Likewise, cyberbullying victimization is also associated with lower levels of life satisfaction. In addition, the adverse associations of cyberbullying victimization in the past 5 years with self-rated health and life satisfaction are weaker among those who attended religious service at least once a week in the past twelve months. A similar pattern is observed for the buffering effect of viewing religious beliefs as very important in the adverse association of cyberbullying victimization in the past 5 years with self-rated life satisfaction. There is also evidence suggesting the gendered buffering effect of the importance of religious beliefs in the association between cyberbullying victimization and self-rated health. This study makes important empirical and theoretical contributions to the growing field of research on the association between cyberbullying victimization and health and well-being and to our understanding of how religion matters to individuals dealing with stressful experiences.

What is the relationship between work-to-family conflict (WFC) and children's problems with school, friends, and health? And does that association depend on household economic conditions and couple relationship quality? Using four waves of longitudinal data from the Canadian Work, Stress, and Heath Study (2011–2017), the present study finds that—overall—both fathers' and mothers' levels of WFC are associated with elevated levels of children's problems over time. However, we also discover that household income and spousal disputes moderate this focal relationship—and they do so differently for mothers and fathers. First, the positive association between WFC and children's problems is stronger for mothers (but not fathers) in households with lower income. Second, the positive association between WFC and children's problems is stronger for fathers (but not mothers) who report more frequent disputes with their spouse. We discuss the implications of these patterns for current theorizing about stress amplification dynamics and situate that discussion within broader ideas in the ecological model of human development.
