A total of 5,726 men from four cycles of the National Health and Nutrition Examination Survey (2011-2018) were included. WWI was calculated as waist circumference divided by the square root of body weight. Multivariate linear regression, segmented linear regression, subgroup analysis, and receiver operating characteristic (ROC) curve analysis were used to evaluate the association and predictive efficacy. Results showed that for every 1 cm/√kg increase in WWI, total BMD decreased by 0.02 g/cm². A turning point of 10.525 cm/√kg was identified for lumbar BMD; below this point, each 1 cm/√kg increase was associated with a 0.09 g/cm² decrease, whereas above this point, the decrease was 0.025 g/cm². Compared with body mass index (BMI) and waist circumference (WC), WWI demonstrated the highest area under the curve (AUC; 65.1%) for predicting low total BMD. WWI was independently associated with lower BMD and can be used as a simple screening indicator for obesity-related bone loss in young and middle-aged American men.</p>","PeriodicalId":7429,"journal":{"name":"American Journal of Men's Health","volume":"20 5","pages":"15579883261495666"},"PeriodicalIF":2.4,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149134749","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Men's Sheds, operating in 12 countries with around 3,000 sheds, offer practical activities, shared purpose, and informal social connection in settings that align with familiar masculine norms while providing support. Despite these benefits, many sheds struggle to maintain member engagement, and little is known about why some men remain involved over the long term while others disengage. This qualitative study, informed by self-determination theory (SDT), explored the processes associated with sustained participation. Twelve retired men aged 65-86 from three Men's Sheds participated in semi-structured interviews. Participants were primarily Anglo-Australian, with memberships ranging from 18 months to 25 years. Reflexive thematic analysis identified six themes: tentative beginnings, membership commitment, friendship and belonging, peer support, learning and mastery, and freedom of choice. Participants often joined following life transitions that had disrupted established sources of connection, purpose, capability, and routine. Continued participation was associated with opportunities for social connection and belonging, skill development and sharing, contributing to others, and exercising meaningful choice. These experiences closely corresponded to the SDT needs for relatedness, competence, and autonomy. The findings suggest that men's sheds may sustain long-term engagement by providing an environment that supports the satisfaction of basic psychological needs and promotes a renewed sense of purpose and well-being among older men.</p>","PeriodicalId":7429,"journal":{"name":"American Journal of Men's Health","volume":"20 5","pages":"15579883261498032"},"PeriodicalIF":2.4,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149163778","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

CP1HD treatment significantly alleviated prostate histopathological damage, reduced the prostate index, and suppressed inflammatory responses. ELISA results showed that CP1HD markedly decreased the levels of TNF-α, IL-6, PGE2, LTB4, and COX-2, while regulating EETs levels, and inhibited M1 macrophage polarization and neutrophil infiltration while promoting M2 polarization. Transcriptomic analysis revealed that CP1HD reversed differentially expressed genes associated with inflammation and arachidonic acid metabolism, which was further confirmed by Western blot analysis of cPLA2, LTA4H, and sEH. In addition, CP1HD modulated gut microbiota composition by restoring the relative abundance of <i>Bacteroides</i>, <i>Alistipes</i>, and the <i>Eubacterium_siraeum group</i>. Metabolomic profiling demonstrated that CP1HD regulated arachidonic acid metabolism and related lipid mediators, with notable effects on phosphatidylethanolamine metabolism and fatty acid β-oxidation.

Rapid urbanisation, psychosocial stress, cardiometabolic transition, and inherited cardiovascular susceptibility converge within contexts characterised by delayed healthcare engagement and fragmented preventive infrastructure. Current prevention strategies remain largely centred on metabolic risk factors and may inadequately capture the multidimensional nature of cardiovascular vulnerability. The objective of this conceptual paper is to develop and present the Triple-Risk Convergence Framework (TRCF), which integrates psychosocial stress, metabolic dysfunction, and lipoprotein(a) [Lp(a)]-associated inherited cardiovascular susceptibility to strengthen early cardiovascular risk recognition and precision prevention among African men. The framework was developed through an integrative narrative synthesis of literature published between 2019 and 2026. Evidence from preventive cardiology, men's health, psychosocial science, cardiovascular genetics, public health, and health systems research was synthesised to identify converging biological, behavioural, and contextual pathways that informed framework development. The conceptual synthesis supports the proposition that premature cardiovascular disease among African men may be more comprehensively understood through the dynamic convergence of psychosocial stress, metabolic dysfunction, and inherited cardiovascular susceptibility than by any single domain considered in isolation. The TRCF proposes that these interacting domains operate across the life course within a broader socioecological context that shapes their exposure, expression, interaction, detection, and management. Rather than constituting a fourth risk domain, social, cultural, environmental, socioeconomic, and health-system determinants are conceptualised as multilevel socioecological influences that shape and modify the three core domains across the life course. By integrating psychosocial assessment, metabolic evaluation, and inherited-risk stratification, the framework extends conventional prevention approaches centred predominantly on metabolic risk factors. The TRCF provides a conceptual foundation for precision prevention of premature cardiovascular disease among African men. By integrating psychosocial stress, metabolic dysfunction, and inherited cardiovascular susceptibility within a multilevel socioecological environment, the TRCF establishes a scientific platform for future empirical validation, implementation research, and precision prevention strategies designed to improve cardiovascular health equity in African populations.</p>","PeriodicalId":7429,"journal":{"name":"American Journal of Men's Health","volume":"20 5","pages":"15579883261490804"},"PeriodicalIF":2.4,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149023770","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previous studies have primarily examined the economic, social, or institutional determinants of life expectancy (LE) in isolation, with limited attention given to their combined effects within a comprehensive analytical framework for China and United States. To address this gap, the present study investigates the determinants of LE by integrating environmental, economic, social, and institutional factors. Specifically, CO2 emissions (CO2e) represent the environmental dimension; GDP and health expenditure capture the economic dimension; population growth and education reflect the social dimension; the rule of law and government effectiveness represent institutional quality. This study estimates three separate models for male life expectancy (MLE), female life expectancy (FLE), and total life expectancy (TLE) using the ARDL model, with the FMOLS estimator employed to assess the robustness of the long-run results. The findings reveal that CO2e and population growth adversely affect MLE, FLE, and TLE in both China and the United States. In contrast, GDP, health expenditure, education, the rule of law, and government effectiveness significantly improve LE across all three models. From a policy perspective, these countries' governments should prioritize reducing CO2e through cleaner energy technologies and stricter environmental regulations while continuing to invest in healthcare systems and educational development. Strengthening institutional quality by enhancing the rule of law and improving government effectiveness can further increase the efficiency and accessibility of health services, thereby contributing to longer LE in both China and the United States.</p>","PeriodicalId":7429,"journal":{"name":"American Journal of Men's Health","volume":"20 5","pages":"15579883261490180"},"PeriodicalIF":2.4,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13583271/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148966109","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This opinion piece proposes the gateway mechanism as a theoretical framework for understanding why music-based interventions may be particularly effective for reaching men who resist conventional services. The gateway mechanism is defined as the process by which a masculinity-congruent, non-clinical activity may create the psychological safety, relational trust, and reduced self-stigma through which men gradually move toward emotional disclosure and eventual help-seeking. Masculinity-congruent refers to activities and framings aligned with values men associate with masculine identity, including competence, agency, and camaraderie, rather than vulnerability or therapeutic dependency. The framework specifies four sequential stages: initial engagement through intrinsic musical appeal; development of psychological safety; emotional expression through and about music; and disclosure and help-seeking that would not otherwise have occurred. It draws on help-seeking theory, self-stigma frameworks, gender role strain theory, and psychological safety literature. Converging evidence from veteran music therapy programs, the Men's Sheds literature, and culturally specific music therapy research supports the framework's predictions. Alternative mechanisms, including the possibility that music functions primarily as a hook into protective social processes such as peer support, camaraderie, and shared identity, are acknowledged. The gateway mechanism is distinguished from health by stealth, gender-sensitive engagement, and sport-as-gateway models by its specification of the sequential psychological process through which musical engagement may produce conditions for emotional opening.
