Racial and Ethnic Differences in Mobile App Use for Meeting Sexual Partners Among Young Men Who Have Sex With Men and Young Transgender Women: Cross-Sectional Study.

Background: Young men who have sex with men and young transgender women (YMSM-YTW) use online spaces to meet sexual partners with increasing regularity, and research shows that experiences of racism online mimics the real world. Objective: We analyzed differences by race and ethnicity in web-based and mobile apps used to meet sexual partners as reported by Chicago-based YMSM-YTW in 2016-2017. Methods: A racially and ethnically diverse sample of 643 YMSM-YTW aged 16-29 years were asked to name websites or mobile apps used to seek a sexual partner in the prior 6 months, as well as provide information about sexual partnerships from the same period. We used logistic regression to assess the adjusted association of race and ethnicity with (1) use of any website or mobile apps to find a sexual partner, (2) use of a "social network" to find a sexual partner compared to websites or mobile apps predominantly used for dating or hookups, (3) use of specific websites or mobile apps, and (4) reporting successfully meeting a sexual partner online among website or mobile app users. Results: While most YMSM-YTW (454/643, 70.6%) used websites or mobile apps to find sexual partners, we found that Black non-Hispanic YMSM-YTW were significantly less likely to report doing so (comparing White non-Hispanic to Black non-Hispanic: adjusted odds ratio [aOR] 1.74, 95% CI 1.10-2.76). Black non-Hispanic YMSM-YTW were more likely to have used a social network site to find a sexual partner (comparing White non-Hispanic to Black non-Hispanic: aOR 0.20, 95% CI 0.11-0.37), though this was only reported by one-third (149/454, 32.8%) of all app-using participants. Individual apps used varied by race and ethnicity, with Grindr, Tinder, and Scruff being more common among White non-Hispanic YMSM-YTW (93/123, 75.6%; 72/123, 58.5%; and 30/123, 24.4%, respectively) than among Black non-Hispanic YMSM-YTW (65/178, 36.5%; 25/178, 14%; and 4/178, 2.2%, respectively) and Jack'd and Facebook being more common among Black non-Hispanic YMSM-YTW (105/178, 59% and 64/178, 36%, respectively) than among White non-Hispanic YMSM-YTW (6/123, 4.9% and 8/123, 6.5%, respectively). Finally, we found that while half (230/454, 50.7%) of YMSM-YTW app users reported successfully meeting a new sexual partner on an app, Black non-Hispanic YMSM-YTW app users were less likely to have done so than White non-Hispanic app users (comparing White non-Hispanic to Black non-Hispanic: aOR 2.46, 95% CI 1.50-4.05). Conclusions: We found that Black non-Hispanic YMSM-YTW engaged with websites or mobile apps and found sexual partners systematically differently than White non-Hispanic YMSM-YTW. Our findings give a deeper understanding of how racial and ethnic sexual mixing patterns arise and have implications for the spread of sexually transmitted infections among Chicago's YMSM-YTW.

Effects of Vitamin D Supplementation and Baseline Vitamin D Status on Acute Respiratory Infections and Cathelicidin: A Randomized Controlled Trial.

Background: Vitamin D supplementation may lower the risk of acute respiratory infection (ARI), and the effects may be mediated through the induction of cathelicidin production. Objective: To study the effect of vitamin D supplementation on ARI and cathelicidin concentration in a randomized controlled trial (RCT) and to study the associations between baseline serum 25 hydroxyvitamin D (25(OH)D) and ARIs and cathelicidin concentrations in a 14-week follow-up study. Methods: In the RCT study, the participants were randomized into 2 groups to receive either 20 µg of vitamin D3 or an identical placebo daily. Blood samples were obtained 3 times, at the beginning (study week 0), mid-term (study week 6), and at the end of the study period (study week 14). The follow-up study had 412 voluntary young men from 2 different locations and seasons (January and July). The primary outcomes were the number of ARIs diagnosed and the number of days off because of ARI. Results: In the RCT, vitamin D supplementation had no effect on ARI or days off because of ARI. However, regardless of the group, vitamin D insufficiency (<50 nmol/L) was associated with increased ARI. In the 14-week follow-up study, insufficient serum 25(OH)D at baseline was also associated with increased risk of ARI (odds ratio [OR], 2.1; 95% confidence interval [CI], 1.2-3.7) and also days-off duty (OR, 2.3; 95% CI, 1.3-4.0) and was inversely associated with cathelicidin concentration (OR, 0.49; 95% CI, .24-.99). Conclusions: Sufficient serum 25(OH)D may be preventive against acute respiratory infection and the preventive effect could be mediated through the induction of cathelicidin production.

Low HIV Testing and PrEP Uptake of Adolescent and Young Men who have Sex with Men in Vietnam.

Little is known about HIV testing, pre-exposure prophylaxis (PrEP) awareness and uptake among adolescent and young men who have sex with men (AYMSM) in Vietnam. We conducted an online survey among AYMSM in Vietnam to determine the prevalence of HIV testing, PrEP awareness, uptake and their correlates. From December 2022-March 2023, 120 HIV-negative AYMSM from 15 to 19 years old in Hanoi and Ho Chi Minh city, Vietnam were recruited through peer referral to complete an online survey, which included questions on demographics, sexual behaviors, HIV risk perception and knowledge, HIV and sexually transmitted infections (STI) testing, PrEP awareness and uptake. Separate multivariable models were used to determine the correlates of HIV testing, PrEP awareness and uptake. Only 58% of participants had ever been tested for HIV. The majority of participants had heard of PrEP before (82%), but only 36% had ever used PrEP. HIV knowledge (aPR (adjusted prevalence ratio) = 1.59; 95%CI:1.06-2.39), a history of STI testing (aPR = 1.32; 95%CI:1.06-1.64), having had anal sex with another man (aPR = 4.49; 95%CI:1.40-14.38) and lower HIV risk perception (aPR = 0.62; 95%CI:0.47-0.83) were associated with HIV testing. HIV knowledge (aPR = 1.38; 95%CI:1.06-1.78) and a history of STI testing (aPR = 1.16; 95%CI:1.03-1.32) were also associated with PrEP awareness. Higher HIV risk perception was negatively associated with PrEP use (aPR = 0.59; 95%CI:0.35-0.99). Our findings underscored the urgent need for further research to explore the causes of the gaps in HIV testing and PrEP use as well as to design innovative interventions tailored to the needs of AYMSM to support HIV testing and PrEP use.

Healthy lifestyle factors and male perpetration of intimate partner violence: a cross-sectional study in Mwanza, Tanzania.

BACKGROUND: In Tanzania, nearly half of ever-married women have experienced some form of intimate partner violence (IPV), yet little knowledge of IPV from the male perspective exists. OBJECTIVE: To explore the role of essential healthy lifestyle factors, diet, sleep, and exercise, and their potential role in IPV perpetration. METHODS: A cross-sectional survey was conducted with 1,002 young men (ages 18-24), 754 of which were in an intimate relationship in the previous year. The study took place in Mwanza, Tanzania and used multivariable logistic regression models to explore associations between male perpetration of IPV and diet, sleep, and exercise. RESULTS: Six types of IPV perpetration were investigated separately and the prevalence of controlling behaviours (79.4%), economic abuse (30.6%), emotional abuse (47.3%), physical violence (16.4%), sexual violence (23.3%), and combined physical and/or sexual violence (32.1%) were obtained. Regular exercise demonstrated a protective effect for economic abuse perpetration; the chance of mildly active individuals perpetrating economic abuse was 38% less than their inactive counterparts (p = 0.003). Associations with sleep were varied and did not show a clear directional relationship. Diet, defined as poor food variety, was positively associated with every IPV type except physical violence and was significant in sexual violence perpetration (aOR:1.57, 95%CI:1.21-2.05). CONCLUSIONS: The results from this study indicate that considering healthy lifestyle behaviours - diet, sleep, and exercise - in the design of intervention programmes may be beneficial in reducing IPV perpetration in Tanzania, and that they should be considered alongside previously established evidence-based risk factors.

Main findings: Physical healthy lifestyle factors may play a weak role in male-perpetrated intimate partner violence but may not be as important as mental health and relationship dynamics.Added knowledge: Limited information exists on potential causes and pathways of male-perpetrated intimate partner violence.Global health impact for policy and action: The results presented can aid in guiding the development of future intimate partner violence interventions and prevention strategies.

Sabelo's Journey as a Young Black Gay Man in South Africa and the Potential of the Grindr App.

Drawing from a case-study, this paper examines 18-year-old Sabelo's journey as a young black gay man in South Africa. Against the backdrop of heteronormativity and entrenched gender roles, Sabelo navigates a landscape where expressions of queer sexuality are often met with resistance. Focusing on a semi-structured interview, Sabelo's narrative reveals the pressure to conform to traditional masculinity and a sense of living a "double life" where acceptance is tied to economic success. Sabelo "acts straight" to manage the obligatory norms around masculinity and "coming out" increased tensions and the pressure to conform. Despite this, the emergence of the dating platform, Grindr, reflects a paradoxical landscape of opportunities and possibilities. Using the concept of the "queer assemblage," the paper argues for the significance of dating apps as more-than-human entities, in providing alternate pathways for sexual expression for young black gay identifying men. In conclusion, digital platforms offer space for transformative potential in subverting heteronormativity and providing queer individuals with spaces for self-expression.

Soccer and Vocational Training are Ineffective Delivery Strategies to Prevent HIV and Substance Abuse by Young, South African Men: A Cluster Randomized Controlled Trial.

HIV and substance abuse are common among young men, associated with a cluster of risk behaviors. Yet, most services addressing these challenges are delivered in setting underutilized by men and are often inconsistent with male identity. This cluster randomized controlled trial aimed to reduce multiple risk behaviors found among young men township areas on the outskirts of Cape Town, South Africa. Young men aged 18-29 years (N = 1193) across 27 neighborhoods were randomized by area to receive HIV-related skills training during either: (1) a 12-month soccer league (SL) intervention; (2) 6-month SL followed by 6 months of vocational training (VT) intervention (SL/VT, n = 9); or 3) a control condition (CC). Bayesian longitudinal mixture models were used to evaluate behaviors over time. Because we targeted multiple outcomes as our primary outcome, we analyzed if the number of significantly different outcomes between conditions exceeded chance for 13 measures over 18 months (with 83%, 76%, and 61% follow-up). Only if there were three significant benefits favoring the SL/VT over the SL would benefits be significant. Outcome measures included substance use, HIV-testing, protective sexual behaviors, violence, community engagement and mental health. Consistent participation in the SL was typically around 45% over time across conditions, however, only 17% of men completed SL/VT. There were no significant differences between conditions over time based on the number of study outcomes. These structural interventions were ineffective in addressing young men's substance abuse and risk for HIV.Clinical Trial Registration: This trial was prospectively registered on 24 November 2014 with ClinicalTrials.gov (NCT02358226).

Novel Machine Learning HIV Intervention for Sexual and Gender Minority Young People Who Have Sex With Men (uTECH): Protocol for a Randomized Comparison Trial.

BACKGROUND: Sexual and gender minority (SGM) young people are disproportionately affected by HIV in the United States, and substance use is a major driver of new infections. People who use web-based venues to meet sex partners are more likely to report substance use, sexual risk behaviors, and sexually transmitted infections. To our knowledge, no machine learning (ML) interventions have been developed that use web-based and digital technologies to inform and personalize HIV and substance use prevention efforts for SGM young people. OBJECTIVE: This study aims to test the acceptability, appropriateness, and feasibility of the uTECH intervention, a SMS text messaging intervention using an ML algorithm to promote HIV prevention and substance use harm reduction among SGM people aged 18 to 29 years who have sex with men. This intervention will be compared to the Young Men's Health Project (YMHP) alone, an existing Centers for Disease Control and Prevention best evidence intervention for young SGM people, which consists of 4 motivational interviewing-based counseling sessions. The YMHP condition will receive YMHP sessions and will be compared to the uTECH+YMHP condition, which includes YMHP sessions as well as uTECH SMS text messages. METHODS: In a study funded by the National Institutes of Health, we will recruit and enroll SGM participants (aged 18-29 years) in the United States (N=330) to participate in a 12-month, 2-arm randomized comparison trial. All participants will receive 4 counseling sessions conducted over Zoom (Zoom Video Communications, Inc) with a master's-level social worker. Participants in the uTECH+YMHP condition will receive curated SMS text messages informed by an ML algorithm that seek to promote HIV and substance use risk reduction strategies as well as undergoing YMHP counseling. We hypothesize that the uTECH+YMHP intervention will be considered acceptable, appropriate, and feasible to most participants. We also hypothesize that participants in the combined condition will experience enhanced and more durable reductions in substance use and sexual risk behaviors compared to participants receiving YMHP alone. Appropriate statistical methods, models, and procedures will be selected to evaluate primary hypotheses and behavioral health outcomes in both intervention conditions using an α<.05 significance level, including comparison tests, tests of fixed effects, and growth curve modeling. RESULTS: This study was funded in August 2019. As of June 2024, all participants have been enrolled. Data analysis has commenced, and expected results will be published in the fall of 2025. CONCLUSIONS: This study aims to develop and test the acceptability, appropriateness, and feasibility of uTECH, a novel approach to reduce HIV risk and substance use among SGM young adults.

Why do young men not seek help for affective mental health issues? A systematic review of perceived barriers and facilitators among adolescent boys and young men.

Men are less likely to seek help for their mental health than women, but less is known about the specific patterns of help-seeking in adolescent boys and young men. This is concerning as adolescent boys and young men have high suicide rates but a low take-up of services. It is therefore of particular importance that the access needs of this group are understood. This review sought to identify the barriers and facilitators faced by adolescent boys and young men in help-seeking for affective mental health disorders. A search of the PubMed, APA PsycInfo, and Cochrane databases identified 3961 articles, of which 12 met the inclusion criteria. Six of the studies were qualitative, five were quantitative and one used mixed methods. Two authors independently extracted data and assessed the quality of the articles. Five key themes were identified, including the impact of social norms, with the subthemes of conformity to masculine norms and self-stigma, limited availability of information about mental health, and 'male-friendly' mental health literacy campaigns. Other themes referred to the help-seeking preferences of adolescent boys and young men, in terms of informal or formal and online or offline help-seeking. Some of the factors were well-researched (e.g., conformity to masculine norms as a barrier) whereas other factors (e.g., self-compassion as a facilitator) were less researched. These barriers and facilitators need to be considered in the development of future strategies to improve the help-seeking behaviour of adolescent boys and young men.

Is device-measured physical activity associated with musculoskeletal disorders among young adult Finnish men?

Background: Musculoskeletal (MSK) disorders represent a significant burden to society and can be unpleasant for the affected individuals. Physical activity (PA) can prevent MSK disorders while conferring other health benefits. The present study aimed to investigate associations between device-measured PA and perceived MSK disorders among young adult men. Methods: PA at different intensity levels, standing, and sedentary behavior were measured with a hip-worn accelerometer in a cohort of 422 young adult Finnish men aged 26 years on average. The incidences of three common MSK disorders (viz., knee pain, lumbar radicular pain, and lumbago pain) during the last month were inquired by a questionnaire. Binary logistic regression was used to examine the associations between the MSK outcomes and explanatory PA variables (PA times at different intensity levels, standing, and sedentary times). The models were controlled for age, education, smoking, BMI, and maximal oxygen uptake. Results: PA, standing, and sedentary times were not significantly associated with the incidence of perceived MSK pain during the last month, except for lumbago pain. Lumbago pain was slightly more probable if the time spent in light PA increased, even after controlling for potential confounding factors, including moderate-to-vigorous PA, with an odds ratio (OR) of 1.07 (95% CI: 1.02-1.14). Sedentary time showed an opposite association, with an OR of 0.98 (95% CI: 0.96-1.00). Conclusions: There were neither positive nor negative clinically meaningful associations between PA and recent MSK disorders among young adult men. The result is surprising and requires further confirmation.

Investigation of readymade garment fit issues and analysis of anthropometric measurements of Ethiopian young men.

This paper presents analyses of anthropometric measurements of Ethiopian young men aged 18-30 years and draws implications for the improvement of the fit of readymade clothing. Thirty-five anthropometric dimensions of 4022 subjects were measured according to ISO 8559:2017. The anthropometric dimensions were described with mean, standard deviation, and some percentiles. Differences in the anthropometric measurements with the body mass index (BMI) and ethnicity of the subjects were examined by analysis of variances. Furthermore, differences in some anthropometric measurements from that of Indian and Greek young men of similar ages were tested by one-sample t-tests. The result showed that the average BMI of the subjects was 20.63 which is normal. Statistically significant mean differences were observed among the subjects with different BMIs and ethnicities in most of the anthropometric dimensions. The anthropometric measurements of the subjects were mostly larger than the Indians and smaller than the Greek men.

An investigation of fit problems with four readymade garments and analyses of anthropometric measurements of Ethiopian young men were conducted. Results indicated anthropometric differences with BMI and ethnicity, and across nations. This has practical implications for global clothing manufacturers to consider the anthropometric characteristics of target markets while manufacturing readymade garments.

Cold hypersensitivity in the hands and feet is associated with erectile dysfunction in young Taiwanese men.

Cold hypersensitivity in the hands and feet (CHHF) is a protective or predisposing factor for many diseases; however, the relationship between CHHF and erectile dysfunction (ED) remains unclear. We aimed to investigate associations between CHHF and ED among young men of Southeast Asian origin. In this cross-sectional study, sexually active Taiwanese men aged 20-40 years were enrolled via an online questionnaire comprising general demographic information, comorbidities, subjective thermal sensations of their hands and feet in the past 6 months, and their erectile function using the International Index of Erectile Function-5 (IIEF-5). Participants who reported cold sensation of hands and feet were classified to have CHHF; those with IIEF-5 score ≤ 21 were considered to have ED. Total 54.2% and 27.9% of participants had ED and CHHF, respectively. Men with CHHF were significantly younger, had lower body mass index and IIEF-5 scores (p < 0.001), and a lower prevalence of diabetes mellitus (p = 0.033) along with higher prevalence of ED, psychiatric disorders, and insomnia (p < 0.001). After adjusting for predisposing factors of ED, CHHF (odds ratio 1.410, 95% confidence interval 1.159-1.714; p = 0.001) remained an independent predictor of ED. Thus, CHHF is independently associated with ED, affecting more than a quarter of young Taiwanese men. Autonomic dysregulation and subclinical endothelial dysfunction may be common pathophysiologies of CHHF and ED.

Machine Learning Prediction of Prediabetes in a Young Male Chinese Cohort with 5.8-Year Follow-Up.

The identification of risk factors for future prediabetes in young men remains largely unexamined. This study enrolled 6247 young ethnic Chinese men with normal fasting plasma glucose at the baseline (FPGbase), and used machine learning (Mach-L) methods to predict prediabetes after 5.8 years. The study seeks to achieve the following: 1. Evaluate whether Mach-L outperformed traditional multiple linear regression (MLR). 2. Identify the most important risk factors. The baseline data included demographic, biochemistry, and lifestyle information. Two models were built, where Model 1 included all variables and Model 2 excluded FPGbase, since it had the most profound effect on prediction. Random forest, stochastic gradient boosting, eXtreme gradient boosting, and elastic net were used, and the model performance was compared using different error metrics. All the Mach-L errors were smaller than those for MLR, thus Mach-L provided the most accurate results. In descending order of importance, the key factors for Model 1 were FPGbase, body fat (BF), creatinine (Cr), thyroid stimulating hormone (TSH), WBC, and age, while those for Model 2 were BF, white blood cell, age, TSH, TG, and LDL-C. We concluded that FPGbase was the most important factor to predict future prediabetes. However, after removing FPGbase, WBC, TSH, BF, HDL-C, and age were the key factors after 5.8 years.

Acceptability of a Self-Guided Lifestyle Intervention Among Young Men: Mixed Methods Analysis of Pilot Findings.

BACKGROUND: Young men are vastly underrepresented in lifestyle interventions, suggesting a need to develop appealing yet effective interventions for this population. OBJECTIVE: This study aimed to determine the acceptability of a self-guided lifestyle intervention designed specifically for young men (age: 18-35 years old). METHODS: Semistructured interviews and surveys were completed by 14 men following completion of a remotely delivered, 12-week lifestyle intervention. The intervention included 1 virtual group session, digital tools, access to self-paced web- and mobile-based content, and 12 weekly health risk text messages. We quantitatively and qualitatively examined young men's experiences with the intervention components of a remotely delivered, self-guided lifestyle intervention targeting weight loss. Data were integrated using convergent mixed methods analysis. RESULTS: Men were a mean age of 29.9 (SD 4.9) years with a mean BMI of 31.0 (SD 4.5) kg/m2. The self-guided aspect was not acceptable, and a majority preferred more check-ins. Participants expressed a desire for a social aspect in future lifestyle interventions. All men found the focus on health risks appealing. A majority of men found the study-issued, Bluetooth-enabled scale acceptable. CONCLUSIONS: Acceptability of the self-guided lifestyle intervention was perceived as suboptimal by young men. The findings highlight the need to add intervention components that sustain motivation and provide additional social support for young men.

Sexual exploitation of young men: Background characteristics and needs from a life-course perspective.

BACKGROUND: Sexually exploited young men are prevalent, yet underrepresented in clinical practice, policy and research. There are multiple barriers that often prevent young men to disclose and to seek or receive support, such as gender norms, limited awareness of victimization and feelings of guilt and shame. OBJECTIVE: By gaining more insight into the background characteristics of young men who experienced sexual exploitation and their needs, this study aims to raise awareness and to better inform policymakers, care- and educational professionals on adequate prevention and intervention efforts. METHODS: Twenty-six young men (age 14-32) who experienced sexual exploitation or other forms of sexual violence in their youth or were at high-risk, participated in this qualitative study that was conducted in The Netherlands. By means of semi-structured interviews and case-file analyses, data was collected to identify risk and protective factors in their life-course and support needs. RESULTS: Several vulnerabilities (e.g. previous experiences of abuse and neglect, household dysfunction, social rejection, running away, substance use) and a lack of positive and supportive relationships led young men into high-risk situations. Among these were involvement in pay dates, criminality and having to survive from day to day, which contributed to victimization. Prevailing gender norms and experiences of stigmatization were often a barrier to express vulnerabilities and to disclose victimization. There was a wide variety in support needs, including peer-to-peer support, therapy, support with day-to-day practices and anonymous support. CONCLUSIONS: These results will contribute to adequate prevention and trauma-informed intervention strategies that meet the unique needs of young men at risk for, or victim of sexual exploitation.

Understanding suicidal ideation disparity between sexual minority and heterosexual Chinese young men: a multiple mediation model of social support sources, self-esteem, and depressive symptoms.

Objectives: Although sexual minorities have reported higher levels of suicidal ideation than heterosexuals across cultures, the role of various psychosocial factors underlying this disparity among young men has been understudied, particularly in China. This study examined the multiple mediating effects of psychosocial factors between sexual orientation and suicidal ideation in Chinese sexual minority and heterosexual young men. Methods: 302 Chinese cisgender men who identified as gay or bisexual, and 250 cisgender heterosexual men (n=552, aged 18-39 years) completed an online questionnaire measuring perceived social support, self-esteem, depressive symptoms, and suicidal ideation. Results: Young sexual minority men reported significantly higher suicidal ideation and lower social support than their heterosexual peers. Structural equation modelling revealed two multiple indirect pathways. One pathway indicated that sexual orientation was indirectly related to suicidal ideation via family support and depressive symptoms. Another pathway indicated that sexual orientation was indirectly related to suicidal ideation via support from friends, self-esteem, and depressive symptoms. Conclusions: This study is among the first to examine the potentially cascading relationships between sexual orientation and psychosocial factors with suicidal ideation in a Chinese sample of young men. The findings highlight several promising psychosocial targets (i.e., improving family/friend support and increasing self-esteem) for suicide interventions among sexual minority males in China.

Prevalence and Predictors of Risky Sexual Behavior Among Young Men in India: Evidence From National Family Health Survey.

Objective: The study examines the prevalence and factors associated with high-risk sexual behavior among sexually active young Indian men. Methods: This study used samples of 14,584 men aged 15 to 29 from the National Family Health Survey (NFHS-5), 2019-21. Results: 14% of men engaged in early sexual debut (<18 years), 68% had unprotected sex, and 4% had multiple sexual partners in the past 12 months. Age, marital status, educational attainment, occupation, wealth quintile, alcohol consumption, internet use, media exposure, and region were significant predictors of risky sexual behavior. Conclusions: We suggest a tailored approach for effective policy design considering risk factors of risky sexual behavior.

The socio-ecological determinants of help-seeking practices and healthcare access among young men: a systematic review.

Delayed engagement with health services is a key contributor to poorer health outcomes experienced by men. Patterns of health service usage which reduce the opportunity for disease prevention and health promotion appear to be especially prominent amongst young men. To identify the multiple and intersecting determinants of young men's help-seeking practices and health services usage, this review uses the social ecological model (SEM) to guide a critical synthesis of the literature on barriers and facilitators experienced by young men in accessing health services. A systematic review was conducted across five databases (MEDLINE, Embase, PsychINFO, CINAHL and Scopus). Included studies presented primary data regarding young men's (12-24 years) barriers and/or facilitators to seeking and accessing health care. Thirty-one studies (24 qualitative and 7 quantitative) underwent data extraction, quality appraisal and thematic analysis under the guiding framework of the SEM. Seven key themes were constructed, encapsulating the perceived barriers and facilitators to help-seeking and accessing health care experienced by young men, including masculine attitudes, health literacy, social pressure, service accessibility, economic factors, service characteristics and cultural attitudes. These findings highlight the complex interplay between the individual, interpersonal, organizational and societal factors impacting young men's healthcare engagement. They also illuminate avenues for multifaceted, context-specific interventions to enhance healthcare accessibility for this group, including addressing health literacy gaps, providing culturally sensitive care and reducing cost barriers.

Evaluation of Current Surgical BPH Interventions for Young and Elderly Men.

PURPOSE OF REVIEW: Benign prostatic hyperplasia affects the quality of life of a significant number of men, especially as they age. There are continuous innovations in the surgical management of benign prostatic hyperplasia, but many of these innovations are studied in the core population of men 50-70 years of age. This review focuses on the outliers of men aged 18-50 and 70 and older. RECENT FINDINGS: Older populations have more comorbidities, higher rates of antithrombotic medications, and advanced symptoms. Properly selected older men can safely have significant objective and subjective improvement in their symptoms. The literature was scarce when evaluating younger men; however, ejaculatory preserving techniques are promising providing improvement in symptoms and preserving ejaculation. This review demonstrates that in properly selected elderly patients, improvements in quality of life while also providing safe surgical interventions can be achieved. Ejaculatory preservation techniques demonstrate promising results, but further studies are required to elucidate true outcomes.

Behavioral Intention of Receiving Monkeypox Vaccination and Undergoing Monkeypox Testing and the Associated Factors Among Young Men Who Have Sex With Men in China: Large Cross-Sectional Study.

BACKGROUND: The worldwide human monkeypox (mpox) outbreak in 2022 mainly affected men who have sex with men (MSM). In China, young men who have sex with men (YMSM) were at a potential high risk of mpox infection due to their sexual activeness and the eased COVID-19 restrictions at the end of 2022. OBJECTIVE: This study aimed to investigate the behavioral intention of receiving mpox vaccination and undergoing mpox testing in 4 different scenarios and explore their associations with background and behavioral theory-related factors among Chinese YMSM. METHODS: An online cross-sectional survey was conducted among YMSM aged 18-29 years from 6 representative provinces of China in September 2022. Participants recruited (recruitment rate=2918/4342, 67.2%) were asked to self-administer an anonymous questionnaire designed based on prior knowledge about mpox and classic health behavior theories. Data on the participants' background, mpox knowledge and cognition, mpox vaccination and testing cognition, and the behavioral intention of receiving mpox vaccination and undergoing mpox testing were collected. Descriptive analysis and univariate and multivariate linear regressions were performed. Geodetector was used to measure the stratified heterogeneity of behavioral intention. RESULTS: A total of 2493 YMSM with a mean age of 24.6 (SD 2.9) years were included. The prevalence of having a behavioral intention of receiving mpox vaccination ranged from 66.2% to 88.4% by scenario, varying in epidemic status and cost. The prevalence of having an mpox testing intention was above 90% in all scenarios regardless of the presence of symptoms and the cost. The positive factors related to vaccination intention included mpox knowledge (ba=0.060, 95% CI 0.016-0.103), perceived susceptibility of mpox (ba=0.091, 95% CI 0.035-0.146), perceived severity of mpox (ba=0.230, 95% CI 0.164-0.296), emotional distress caused by mpox (ba=0.270, 95% CI 0.160-0.380), perceived benefits of mpox vaccination (ba=0.455, 95% CI 0.411-0.498), self-efficacy of mpox vaccination (ba=0.586, 95% CI 0.504-0.668), and having 1 male sex partner (ba=0.452, 95% CI 0.098-0.806), while the negative factor was perceived barriers to vaccination (ba=-0.056, 95% CI -0.090 to -0.022). The positive factors related to testing intention were perceived severity of mpox (ba=0.283, 95% CI 0.241-0.325), perceived benefits of mpox testing (ba=0.679, 95% CI 0.636-0.721), self-efficacy of mpox testing (ba=0.195, 95% CI 0.146-0.245), having 1 male sex partner (ba=0.290, 95% CI 0.070-0.510), and having in-person gatherings with MSM (ba=0.219, 95% CI 0.072-0.366), while the negative factor was emotional distress caused by mpox (ba=-0.069, 95% CI -0.137 to -0.001). CONCLUSIONS: Among Chinese YMSM, the intention of undergoing mpox testing is optimal, while the mpox vaccination intention has room for improvement. A future national response should raise YMSM's mpox knowledge, disseminate updated information about mpox and preventive measures, improve preventive service accessibility and privacy, and provide advice on positively coping with the associated emotional distress.

The association between dietary total antioxidant capacity and hearing loss: results from the Tehran employees Cohort Study.

BACKGROUND: Despite numerous studies that have explored the association between individual antioxidants or specific combinations and the risk of hearing loss, there is lack of information regarding the relationship between dietary total antioxidant capacity (dTAC) and hearing loss. The conflicting results on this association further highlight the need for more research in this area. This study aims to investigate the association between overall dietary antioxidant intake and the risk of hearing loss among Iranian adults. METHODS: This cross-sectional study recruited 3443 adult participants aged between 19 and 67 years (with an average age of 41.4 years ± 8.8) who were employed at Tehran University of Medical Sciences in Iran. Participants underwent dietary assessment using a validated Food Frequency Questionnaire (FFQ). The hearing status of each participant was evaluated by a licensed audiologist in a soundproof room, using diagnostic audiometry that adhered to American National Standards specifications and followed standard audiometric clinical procedures. The dietary total antioxidant capacity (dTAC) was calculated using the Ferric Reducing-Antioxidant Power (FRAP) values. RESULTS: 43.6% of male participants had hearing loss, while 26.8% among female participants. After accounting for various confounding factors, no significant association was observed between higher levels of dTAC and reduced odds of hearing loss in the overall population. However, among men under the age of 40, higher levels of dTAC were associated with decreased odds of hearing loss, even after adjusting for several covariates (OR: 0.56, 95% CI: 0.31-1.02, Ptrend = 0.02). This relationship was not evident in men over 40 years of age or among women. CONCLUSION: The study found an inverse relationship between higher antioxidant intake in the diet and lower odds of hearing loss, specifically among men who were 40 years old or younger. However, this relationship was not observed in the overall population or among women. Additional prospective studies are necessary to validate these results.
