Diversity of social networks versus quality of social support: Which is more protective for health-related quality of life among older adults?

Social, Racial, and Cultural Considerations in Hypertension in Older Adults

Black and Hispanic older adults in the United States have higher prevalence of hypertension, less adequate treatment, less consistent blood pressure control, and worse cardiovascular outcomes than their white counterparts. Genetic differences are insufficient to explain these disparities-various social, economic, and environmental factors notably contribute. Racial and ethnic differences in living circumstances, household income, access to appropriate care, food security, educational attainment, and tobacco use all negatively impact long-term hypertension outcomes in minoritized older adults. To remedy these inequities, the search for solutions must include a complete assessment of the social, racial, and cultural components of the problem.

The impact of social support on university students living with mental illness: a systematic review and narrative synthesis

BACKGROUND

Limited reviews address the role of social support for university students with mental health issues, despite its proven significance for other vulnerable groups.

AIMS

The current review aims to examine the current evidence on the nature and impact of social support for students with self-reported and diagnosed mental health problems, along with the availability and effectiveness of social support interventions.

METHODS

Electronic databases (CENTRAL, CINAHL, Embase, HMIC, MEDLINE, PsycINFO, SCOPUS, Web of Science) and grey literature databases (EThOS, SSRN) were systematically searched from inception to March 2024 Articles were eligible for inclusion if they reported on the nature and role of social support for university students with mental health problems. Data from included articles were extracted and narratively synthesised. Quality of included studies was assessed using the Mixed Methods Appraisal Tool.

RESULTS

Ten studies, involving 3669 participants, were included. Findings indicated high social support significantly mitigated against suicide, depression, anxiety, and psychological distress. Barriers to support access and both positive and negative impacts on mental health were identified.

CONCLUSIONS

Results underscore the need to consider the distinct support requirements of students with mental health problems, who often face insufficient access to high social support. This emphasises the potential for effective interventions in this population.

National trends and correlates of treatment resistance in major depressive episode and associated suicidal ideation and behaviors among adults in the United States

OBJECTIVE

To examine recent 12-year trends in prevalence of suicidal ideation and behaviors (SIBs) among US adults experiencing a past-year treatment-resistant depression (TRD).

METHODS

Using data from the National Survey of Drug Use and Health, we estimated the annual percentage of individuals aged ≥18 with TRD who reported past-year SIBs, and estimated linear trends adjusting for potentially confounding factors from 2009 to 2020.

RESULTS

Of estimated 237.5 million US adults, 7.1 % met diagnostic criteria for a past-year major depressive episode (MDE) between 2009 and 2020. Of these, 9.7 % met criteria for TRD. The proportion reporting past-year suicidal ideation in TRD ranged from 39.5 % (95 % confidence interval [CI], 32.1-47.3 %) in 2009-2010 to 43.4 % (95 % CI, 36.7-503 %) in 2019-2020, with an average annual percent change (AAPC) of 1.3 % (95 % CI, -0.7 % to 3.3 %). The prevalence of past-year suicide attempts in TRD was 7.3 % across the study period (AAPC, 0.1 %; 95 % CI, -4.3 % to 4.7 %). Past-year SIBs were significantly associated with an increased likelihood of meeting criteria for TRD among adults with MDE (adjusted odds ratio [AOR], 1.53; 95 % CI, 1.35-1.75 for suicidal ideation; AOR, 2.17; 95 % CI, 1.79-2.62 for suicide attempts). No significant differences were observed between 2019 and 2020, reflecting the COVID-19 pandemic.

CONCLUSION

Among individuals with TRD, proportions of SIBs are high. These findings underscore an urgent need for suicide prevention efforts in this high-risk population, including preventive services across diverse settings and accessibility to evidence-based pharmacological and non-pharmacological interventions.

Effect of social capital, social support and social network formation on the quality of life of American adults during COVID-19

This study aims to evaluate the effect of social capital (SC), social support (SS), and social network formation (SNF) on the quality of life of American adults during COVID-19. Using a probability sample of American adults aged 49+, 2370 respondents were selected from the National Social Life Health and Aging Project (NSHAP) dataset for analysis using an integrated partial least squares based on structural equation modeling (PLS-SEM)-K-fold cross-validation approach. The analysis showed that social capital assessed using civic engagement, social cohesion, socioeconomic status (SES), social support, and social network formation were significantly and positively associated with American adults' quality of life during the COVID-19 pandemic. Furthermore, the results showed that using the PLS-SEM and K-fold cross-validation approach produced a medium predictive power of the overall model, confirming the importance of SC, SS, and SNF in predicting quality of life-outcomes. These findings suggest that efforts to promote the well-being of American adults, especially older adults, during the pandemic should focus on strengthening social capital, social support and social network formation.

Patterns of Social Isolation and Low Social Support and Frailty Trajectories Among Chinese Older Adults

Objectives: This study aims to identify patterns of social isolation and low social support, and discover their associations with frailty trajectories among Chinese older adults. Methods: The paper used five waves of the Chinese Longitudinal Healthy Longevity Survey (CLHLS, 2005-2018). The latent class analysis, multi-trajectory modeling, and the multinomial logistic regression approaches were used to perform the analysis. Results: The paper identified five types of social isolation and low social support, and three typical frailty trajectories. Patterns of social isolation and low social support were associated with frailty trajectories among older adults. Conclusions: Distinct patterns of social isolation and low social support were significantly correlated with frailty trajectories. To improve frailty trajectories among older adults, interventions such as Healthy China 2030 should prioritize addressing the interplay between social isolation and low social support.

MOFGalaxyNet: a social network analysis for predicting guest accessibility in metal-organic frameworks utilizing graph convolutional networks

Metal-organic frameworks (MOFs), are porous crystalline structures comprising of metal ions or clusters intricately linked with organic entities, displaying topological diversity and effortless chemical flexibility. These characteristics render them apt for multifarious applications such as adsorption, separation, sensing, and catalysis. Predominantly, the distinctive properties and prospective utility of MOFs are discerned post-manufacture or extrapolation from theoretically conceived models. For empirical researchers unfamiliar with hypothetical structure development, the meticulous crystal engineering of a high-performance MOF for a targeted application via a bottom-up approach resembles a gamble. For example, the precise pore limiting diameter (PLD), which determines the guest accessibility of any MOF cannot be easily inferred with mere knowledge of the metal ion and organic ligand. This limitation in bottom-up conceptual understanding of specific properties of the resultant MOF may contribute to the cautious industrial-scale adoption of MOFs.Consequently, in this study, we take a step towards circumventing this limitation by designing a new tool that predicts the guest accessibility-a MOF key performance indicator-of any given MOF from information on only the organic linkers and the metal ions. This new tool relies on clustering different MOFs in a galaxy-like social network, MOFGalaxyNet, combined with a Graphical Convolutional Network (GCN) to predict the guest accessibility of any new entry in the social network. The proposed network and GCN results provide a robust approach for screening MOFs for various host-guest interaction studies.

Pain Management in Older Adults Before and During the First Year of COVID-19 Pandemic: Prevalence, Trends, and Correlates

BACKGROUND

There is limited knowledge on whether and how health care access restrictions imposed by the coronavirus disease of 2019 pandemic have affected utilization of both opioid and nonpharmacological treatments among US older adults living with chronic pain.

METHODS

We compared prevalence of chronic pain and high impact chronic pain (ie, chronic pain limiting life or work activities on most days or every day in the past 6 months) between 2019 (pre-pandemic) and 2020 (first year of pandemic) and utilization of opioids and nonpharmacological pain treatments among adults aged ≥65 years enrolled in the National Health Interview Survey, a nationally representative sample of noninstitutionalized civilian U.S. adults.

RESULTS

Of 12 027 survey participants aged ≥65 (representing 32.6 million noninstitutionalized older adults nationally), the prevalence of chronic pain was not significantly different from 2019 (30.8%; 95% confidence interval [CI], 29.7%-32.0%) to 2020 (32.1%; 95% CI, 31.0%-33.3%; p = .06). Among older adults with chronic pain, the prevalence of high impact chronic pain was also unchanged (38.3%; 95% CI, 36.1%-40.6% in 2019 versus 37.8%; 95% CI, 34.9%-40.8% in 2020; p = .79). Use of any nonpharmacological interventions for pain management decreased significantly from 61.2% (95 CI, 58.8%-63.5%) in 2019 to 42.1% (95% CI, 40.5%-43.8%) in 2020 (p < .001) among those with chronic pain, as did opioid use in the past 12 months from 20.2% (95% CI, 18.9%-21.6%) in 2019 to 17.9% (95% CI, 16.7%-19.1%) in 2020 (p = .006). Predictors of treatment utilization were similar in both chronic pain and high-impact chronic pain.

CONCLUSION

Use of pain treatments among older adults with chronic pain declined in the first year of coronavirus disease of 2019 pandemic. Future research is needed to assess long-term effects of coronavirus disease of 2019 pandemic on pain management in older adults.

Does social isolation affect physical and mental health? A test of the social causation hypothesis using dynamic panel models with fixed effects

OBJECTIVES

The widely acknowledged negative association between social isolation and physical and mental health is commonly interpreted in terms of social causation and has served as an important frame of reference for many interventions. However, evidence of social causation is likely biased because most studies cannot differentiate between social causation and health selection. The public attention given to this field of research indicates a need for analytical strategies that improve the understanding of the underlying link between social isolation and physical and mental health.

METHODS

Using data from the German Socio-Economic Panel (GSOEP) study (2004 to 2012) of 6740 men and 7189 women aged 50 and above, we estimated dynamic panel models with fixed effects that allow us to probe the social causation hypothesis while accounting for direct selection (reverse causality) and indirect selection (unobserved heterogeneity). All analyses were conducted for women and men separately.

RESULTS

We found that social isolation adversely affected mental health among older men and women to a degree that suggests practical relevance. However, we could not find a similar effect on physical health. A considerable part of the association between social isolation and both health outcomes was attributable to indirect selection, whereas direct selection led to underestimating the relevance of social isolation for mental health.

CONCLUSION

The results provide more convincing evidence that social isolation has adverse effects on mental health among older people. We conclude that effective interventions targeting social isolation might indeed be suitable for improving mental health among older people.

MOFSocialNet: Exploiting Metal-Organic Framework Relationships via Social Network Analysis

The number of metal-organic frameworks (MOF) as well as the number of applications of this material are growing rapidly. With the number of characterized compounds exceeding 100,000, manual sorting becomes impossible. At the same time, the increasing computer power and established use of automated machine learning approaches makes data science tools available, that provide an overview of the MOF chemical space and support the selection of suitable MOFs for a desired application. Among the different data science tools, graph theory approaches, where data generated from numerous real-world applications is represented as a graph (network) of interconnected objects, has been widely used in a variety of scientific fields such as social sciences, health informatics, biological sciences, agricultural sciences and economics. We describe the application of a particular graph theory approach known as social network analysis to MOF materials and highlight the importance of community (group) detection and graph node centrality. In this first application of the social network analysis approach to MOF chemical space, we created MOFSocialNet. This social network is based on the geometrical descriptors of MOFs available in the CoRE-MOFs database. MOFSocialNet can discover communities with similar MOFs structures and identify the most representative MOFs within a given community. In addition, analysis of MOFSocialNet using social network analysis methods can predict MOF properties more accurately than conventional ML tools. The latter advantage is demonstrated for the prediction of gas storage properties, the most important property of these porous reticular networks.

Does Diversity of Social Ties Really Matter More for Health and Leisure Activity than Number of Social Ties? Evidence from Later Adulthood

OBJECTIVES

Claims that the diversity of social ties matters more for health than the sheer number of ties have largely gone untested. This study accordingly compared the unique associations of number versus diversity of social ties with key health-related outcomes: functional limitations and leisure activities. Additionally, positive and ambivalent ties were distinguished.

METHODS

Social networks, health, and leisure activities were assessed in a national sample of older adults (N = 874; ages 65-91).

RESULTS

Regression analyses revealed that number of ties related to each outcome at a magnitude comparable to, or exceeding, that of diversity in most models. For positive ties, number related more strongly than diversity to greater leisure activities. For ambivalent ties, number related more strongly than diversity to worse functional limitations.

DISCUSSION

Contrary to prevailing views, diversity of ties is not necessarily more important than number of ties. Findings extend scientific understanding and approaches to interventions.
