Telomere length, a biomarker of human aging, is related to adverse health outcomes. Growing evidence indicates that oxidative stress and inflammation contributes to telomere shortening, whereas social support may protect from telomere shortening. Despite sex differences in telomere length and social support, little is known about whether there are sex differences in the relationship between oxidative stress/inflammation and telomere length, and sex-specific moderating roles of social support in older adults. Using data from the National Health and Nutrition Examination Survey (NHANES) 1999-2002, this study assessed whether the associations between oxidative stress/inflammation and telomere length vary with sex and explored social support as a moderator in these associations among 2289 older adults. Oxidative stress was measured based on serum Gamma-glutamyl transferase (GGT), and inflammation was measured based on C-reactive protein (CRP). After adjusting for the covariates, GGT was significantly associated with telomere length in females only (β =  - 0.037, 95% CI =  - 0.070, - 0.005), while CRP was associated with telomere length in males only (β =  - 0.019, 95% CI =  - 0.035, - 0.002). Moreover, high social support mitigated the negative association between GGT and telomere length, which was more evident in females. Furthermore, social support moderated the association between CRP and telomere length in males aged 70 and above. Our findings indicated that biological mechanisms related to telomere length may vary with sex, while social support plays a sex-specific moderating role.

Previous research has shown that informal caregiver burden can have deleterious effects on patient recovery; however, this relationship has yet to be investigated in patients undergoing coronary artery bypass graft (CABG) surgery. This study aimed to examine the impact of the change of caregiver burden from pre- to post-surgery on patients' mental and physical health after CABG surgery. Ninety patient-caregiver dyads were assessed one month before the surgery, two months and one year after the surgery. Caregivers completed the Oberst Burden Scale to measure caregiver burden. Patients completed the Beck Depression Inventory to measure depressive symptoms, a subscale of the Hospital Anxiety and Depression Scale to measure anxiety symptoms, the Short Form-12 health assessment to measure health-related quality of life, and the Coronary Revascularisation Outcomes Questionnaire to measure surgery symptoms. Hierarchical linear regression analyses were conducted to explore the association between change in caregiver burden and post-surgery patient outcomes. A greater increase in caregiver burden from pre- to two-months post-surgery significantly predicted higher patients' depressive symptoms (β = 0.179, p = 0.010), anxiety symptoms (β = 0.114, p = 0.017), reported post-surgery symptoms (β = 0.335, p = 0.008) and reduced physical health-related quality of life (β = -0.358, p = 0.003), after controlling for a wide range of covariates. These findings were not replicated at a one-year follow-up. These results provide insights into the impact of caregiver burden on patient distress following CABG surgery, supporting the idea of psychological support interventions for caregivers to increase patients' short-term recovery outcomes.

Though men who have sex with men (MSM) are disproportionately affected by sexually transmitted infections (STIs), factors that impact STI testing adherence among non-single MSM remain under-explored. While being in a relationship per se does not necessarily increase one's risk for STIs, certain behavioral risks and demographic factors may impact STI testing adherence. Through a sample of 296 non-single MSM located in the United States, we examined key behavioral and demographic factors and their associations with adherence to CDC's STI testing guidelines. Overall, the results showed inconsistent STI testing adherence rates among divergent subgroups of higher-risk non-single MSM. First, non-single MSM who take PrEP were more likely to adhere to STI testing and showed significantly higher adherence rates than those who do not take PrEP, but adherence rates were not related to nor significantly different than those who reported extra-relational sex or condomless anal sex. Further, STI testing adherence was positively associated with having a shorter relationship length, identifying as non-White, and living in an LGBTQ+-friendly neighborhood. Practical implications and recommendations for clinical practices, persuasive messages, and promotion strategies are discussed.

Recognizing the real-life impact of racial stress on physical and psychological health is vital for creating impactful health promotion interventions among African American families. Despite the known link between racial stress and poor physical health outcomes, no existing intervention to date has targeted stress management strategies to buffer racial stress and build positive health behaviors among African American families. The current study outlines the lessons learned throughout the development of the Linking Exercise for Advancing Daily Stress (LEADS) Management and Resilience program, a 10-week family-based health promotion, stress management, and resilience intervention that aimed to improve physical activity, healthy eating, and well-being among African American adolescents and parents. We highlight the evolution of the LEADS intervention from a health promotion and stress management intervention to a culturally salient health promotion, stress management, and resilience intervention utilizing community-based participatory research strategies. This paper chronicles our systematic journey in making those changes and the lessons we learned along the way. We provide specific recommendations and implications for future health promotion interventions developed for African American families. Overall, we argue for a research orientation that respects cultural and racial contexts, embraces diversity within research teams and self-reflection, recognizes the heterogeneity among African American populations, and applies strength-based approaches.

Much of the research on the effects of syndemics on HIV outcomes has utilized an additive approach. However, interaction effects may better account for syndemic synergy than an additive approach, but it remains difficult to specify interaction effects without empirical guidance. We sought to systematically compare additive and interaction effects approaches to modeling the effects of syndemic problems on antiretroviral therapy (ART) using empirically specified interaction terms. Participants were 194 people with HIV (PWH) who received HIV care in Khayelitsha, South Africa. In a series of linear regression models, we examined ten syndemic problems: depression, alcohol use, intimate partner violence (IPV), post-traumatic stress, social anxiety, substance use, food insecurity, poverty, housing instability, and structural barriers to care. Depression, substance use, and food insecurity were selected for interaction terms based on a prior network analysis, which found these problems to be most central. The additive models did not produce statistically significant findings. However, the interaction effects models yielded significant interaction terms in both the full model and a parsimonious model. There was a statistically significant effect of the interaction between depression and food insecurity on ART adherence (b = 0.04, Robust SE = 0.02, 95%CI [0.001-0.08], p = .012). This pattern of results was replicated in the parsimonious model. Findings suggest that when feasible, interaction effects approaches may be a helpful syndemic modeling technique. Results may inform future intervention targets, such as depression and food insecurity, and the importance of addressing both structural and psychosocial syndemic problems.

Approximately 28% of American adults meet both the physical activity (PA) and strength training guidelines despite the numerous health benefits associated with a physically active lifestyle. The purpose of this paper is to provide an update of the 2017 Society of Behavioral Medicine PA Special Interest Group article that outlined future directions in sedentary time reduction interventions, technology-based PA interventions, and the dissemination and implementation of PA interventions. Since the prior review, there has been significant progress on effective interventions for reducing sedentary time. However, there has been less progress for improving the specificity of sedentary time guidelines. There has been a dramatic increase in the number of studies examining PA mHealth interventions and support for mHealth intervention has generally been positive, though sustaining engagement in mHealth interventions remains a challenge. Promising newer technologies that have been explored more extensively since the prior review including artificial intelligence (AI). Knowledge of how to implement and scale-up effective PA interventions has also increased. Several current trends in PA intervention research that continue to advance the field include examining the moderating effect of the built environment on the effectiveness of behavioral interventions, cultural tailoring of interventions, Just in Time Adaptive Interventions (JITAIs), and exercise snacks (vigorous intensity PA sessions that are less than one minute). Overall, there has been significant progress in the PA intervention field but significant work remains for creating effective interventions that can be readily implemented into real world settings.

Self-management of diabetes is extremely challenging and non-adherence is common. Health consequences are significant for those unable to adhere to the complex treatment regimen, which includes regular oral medication and/or insulin use, frequent blood sugar checks, strict dietary management, and regular physical activity. Mobile applications (apps) present a tremendous opportunity to help patients improve adherence to these behaviors. The availability of commercial diabetes self-management apps is increasing exponentially, making it difficult for patients and providers to stay informed about app options and benefits. Previous reviews have described commercial diabetes apps and their features and usability for patients with diabetes. A smaller number have reviewed the effectiveness of these apps in improving blood glucose as well as other aspects of diabetes management. The aim of this article is to update our 2016 review, summarize the results of new reviews, review outcomes of diabetes apps described in the literature, and offer recommendations for app features, effectiveness research, and marketing in apps for diabetes self-management. Although higher-quality research is needed, current reviews suggest that many diabetes apps are effective in lowering HbA1c. Recommendations for future research include reporting critical details such as patient demographics and intervention elements and designing studies to identify the most effective components of diabetes management apps. Furthermore, clearly labeling apps that have data supporting clinical efficacy in app stores would allow both providers and patients to easily identify apps that might be most beneficial. Future research should explore the use of apps for the prevention of diabetes in individuals diagnosed with prediabetes.

Consistent evidence suggests that exercise leads to improvements in subjective sleep quality and also objective sleep metrics in non-psychiatric adult populations. However, the degree to which exercise provides sleep benefits for adults with psychiatric disorders is less known, despite the potential benefits given that sleep disturbance is prevalent in these populations. In this narrative review, we synthesize results of randomized controlled trials examining the influence of aerobic and/or resistance exercise interventions on sleep outcomes in adult psychiatric populations. We specifically focus on populations with elevated symptoms or diagnoses of depression, anxiety, or posttraumatic stress disorder. A systematic search through June 2024 yielded 26 relevant trials. Overall, most trials reported improvement of subjective sleep quality after aerobic and/or resistance exercise programs in samples with depression. Similar effects were observed for posttraumatic stress; however, larger trials are needed. Further research is needed to examine the impact of exercise on sleep in anxiety populations as only one trial with mixed results was identified. Results were more equivocal for the subpopulation of adult women with perinatal or postpartum depression, demonstrating the importance of understanding exercise effects on sleep in specific subpopulations. Few studies examined objective sleep outcomes, impact of acute exercise on next day sleep, or the interplay between exercise, sleep, and psychiatric symptom changes, all important areas of future research. Other implications and future directions are discussed, including potential moderators and mechanisms of action that warrant further study to better understand how exercise interventions may optimally target sleep in psychiatric populations.

To evaluate the association between self-reported gun violence exposures and mental health and behavioral health indicators in a rural population. Using cross-sectional survey responses from 630 residents of a rural county in Pennsylvania, logistic regression models estimate the likelihood of residents indicating moderate or severe levels of health outcomes as a function of gun violence exposure. We control for a series of variables related to gun ownership, behavior, history with firearms and demographic characteristics. Personal firearm victimization was associated with self-reported depressive symptoms and interrupted sleep. Secondary exposure to firearm violence, particularly exposure to friends attempting or completing a suicide, was associated with higher odds of reporting severe levels (14 days or more in the past month) of depressive symptoms, anxiety, and poor sleep. For firearm suicide involving a friend or family member, the odds of reporting severe levels of all three outcomes are 3 times greater (OR 2.984, 95% CI 1.457-6.108). For each additional firearm exposure, the odds of experiencing severe levels of mental health and sleep difficulties are 1.4 times greater (OR 1.384, 95% CI 1.115-1.720). Cumulative exposures also increase the odds of reporting binge drinking and drug use. Firearm violence exposure was associated with adverse health indicators in this rural population. Approaches to counter the effects of cumulative firearm exposure and firearm suicide exposure, including reinvigorating community spaces and strengthening social supports, may help to reduce mental health burden in rural communities.

This study investigated the associations between personality traits of the Five Factor Model and cardiovascular mortality, with a specific focus on whether pre-existing cardiovascular conditions modified these associations. We used data from 43,027 participants across five cohort studies: Health and Retirement Study (HRS); Wisconsin Longitudinal Study (WLS); National Social Life, Health, and Aging Project (NSHAP); Midlife in the United States (MIDUS); Household, Income, and Labour Dynamics in Australia (HILDA) with a mean age 55.9 years and 6493 individuals with pre-existing cardiovascular disease. We conducted meta-analyses examining conscientiousness, emotional stability, agreeableness, openness to experience, and extraversion in relation to mortality due to coronary heart disease and stroke. During a mean follow-up of 12.1 years, 1620 participants died from coronary heart disease and 454 from stroke. Lower conscientiousness was associated with higher mortality risk from both coronary heart disease (hazard ratio per 1SD = 0.82, 95%CI = 0.75-0.90) and stroke (HR = 0.84, CI = 0.72-0.99). Lower emotional stability predicted increased coronary heart disease mortality (HR = 0.91, CI = 0.85-0.97). The association between conscientiousness and cardiovascular mortality did not differ between individuals with or without baseline cardiovascular conditions. In addition, adjustments for health behaviors and other covariates only slightly attenuated this association. Other personality traits were not associated with cardiovascular disease mortality. Our findings highlight the role of low conscientiousness, and to a lesser extent low emotional stability, in the development and progression of fatal cardiovascular disease through pathways that may extend beyond established health behaviors.
