Comparative effectiveness of N95, surgical or medical, and non-medical facemasks in protection against respiratory virus infection: A systematic review and network meta-analysis.

The aim of this systematic review and network meta-analysis is to evaluate the comparative effectiveness of N95, surgical/medical and non-medical facemasks as personal protective equipment against respiratory virus infection. The study incorporated 35 published and unpublished randomized controlled trials and observational studies investigating specific mask effectiveness against influenza virus, SARS-CoV, MERS-CoV and SARS-CoV-2. We searched PubMed, Google Scholar and medRxiv databases for studies published up to 5 February 2021 (PROSPERO registration: CRD42020214729). The primary outcome of interest was the rate of respiratory viral infection. The quality of evidence was estimated using the GRADE approach. High compliance to mask-wearing conferred a significantly better protection (odds ratio [OR], 0.43; 95% confidence interval [CI], 0.23-0.82) than low compliance. N95 or equivalent masks were the most effective in providing protection against coronavirus infections (OR, 0.30; CI, 0.20-0.44) consistently across subgroup analyses of causative viruses and clinical settings. Evidence supporting the use of medical or surgical masks against influenza or coronavirus infections (SARS, MERS and COVID-19) was weak. Our study confirmed that the use of facemasks provides protection against respiratory viral infections in general; however, the effectiveness may vary according to the type of facemask used. Our findings encourage the use of N95 respirators or their equivalents (e.g., P2) for best personal protection in healthcare settings until more evidence on surgical and medical masks is accrued. This study highlights a substantial lack of evidence on the comparative effectiveness of mask types in community settings.

Associations between workplace characteristics and 'outness' in LGBTI workers in Austria.

OBJECTIVES: Lesbian, gay, bisexual, transgender and intersex (LGBTI) individuals are often subjected to negative attitudes in the workplace, which may lead to non-disclosure of their sexual orientation and/or gender identities. We aimed to determine the prevalence of workplace disclosure of sexual or gender identity (ie, 'outness'; being 'out') and to examine its associations with workplace characteristics in LGBTI workers in Austria. METHODS: This cross-sectional study analysed sociodemographic, work-related and well-being-related data from self-identifying gender and/or sexual minority participants elicited by an online questionnaire between February and June 2017. From the initial 1268 respondents, 1177 (93%) provided complete data and were included in the subsequent analyses. RESULTS: The largest proportion of the sample were 26-35 years old (39.1%), cisgender gay men (40.0%) in full-time employment (63.9%). Overall, 51.7% of the sample were 'out' at the workplace. Being bisexual (OR=0.46, 95% CI 0.27 to 0.81), the provision of antidiscrimination guidelines in the workplace (OR=0.53, 95% CI 0.32 to 0.90), living alone (OR=0.50, 95% CI 0.32 to 0.79) and in shared households (OR=0.49, 95% CI 0.25 to 0.96) were associated with a decreased likelihood of being 'out' at work.Factors associated with being 'out' at work were being middle aged (36-45 years old; OR=1.74, 95% CI 1.07 to 2.85), having been in employment for >10 years (OR=2.03, 95% CI 1.08 to 3.81), an LGBTI-friendly work environment (OR 1.61, 95% CI 1.36 to 1.91), labour-management antidiscrimination contract (OR=2.02, 95% CI 1.23 to 3.32) and work council protections (OR=1.56, 95% CI 1.04 to 2.36). CONCLUSIONS: Instating antidiscrimination protections might facilitate 'outness' of LGBTI workers and lead to a better promotion of diversity in the workplace.

Ejaculation Disorders in Male Patients with Cancer: A Systematic Review and Meta-Analysis of Prevalence.

PURPOSE: Ejaculatory dysfunction (EjD) and erectile dysfunction after cancer treatment are clinically important complications, but their exact prevalence by various kinds of cancer site and type of treatment is unknown. The aim of this systematic review and meta-analysis was to examine the available evidence and provide pooled estimates for prevalence of EjD and erectile dysfunction in relation to all cancer sites and identify characteristics associated with EjD in cancer patients. MATERIALS AND METHODS: We performed a systematic review and meta-analysis of cross-sectional and case-control studies. We searched 4 electronic databases (Medline®, CINAHL, PsychInfo and Embase®) until July 22, 2020. All retrospective or prospective studies reporting the prevalence of EjD in male patients with cancer were included in this review. A random effects meta-analysis was conducted calculating prevalence proportions with 95% confidence intervals. Prevalence proportions were calculated for the incidences of EjD by cancer site and type of treatment. RESULTS: A total of 64 studies (a total of 10,057 participants) were included for analysis. The most common cancer sites were bladder, colon, testis and rectum. The prevalence rates of EjD after surgical intervention ranged from 14.5% (95% CI 2.2-56.3) in colon cancer to 53.0% (95% CI 23.3-80.7) in bladder cancer. The prevalence rates of erectile dysfunction ranged from 6.8% (95% CI 0.8-39.1) in bladder cancer to 68.7% (95% CI 55.2-79.6) in cancer of the rectum. CONCLUSIONS: In a large study-level meta-analysis, we looked at a high prevalence of EjD and erectile dysfunction at various cancer sites and across different treatment types. Prospective studies of EjD and erectile dysfunction after various kinds of cancer treatments are warranted.

Relationship between sexual orientation and psychotic experiences in the general population in England.

BACKGROUND: Non-heterosexual individuals are at high risk for a variety of factors associated with the emergence of psychotic experiences (PEs) (e.g. common mental disorders, substance use, and stress). However, there is a scarcity of data on the association between sexual orientation and PEs. Therefore, the aim of this study was to examine the sexual orientation-PE relationship, and to identify potential mediators in this relationship. METHODS: This study used nationally representative cross-sectional data from the 2007 Adult Psychiatric Morbidity Survey. Sexual orientation was dichotomized into heterosexual and non-heterosexual. Past 12-month PE was assessed with the Psychosis Screening Questionnaire. Regression and mediation analyses were conducted to analyze the association between sexual orientation and PEs, and to identify potential mediators involved in this relationship. RESULTS: The final sample consisted of 7275 individuals aged ⩾16 years. The prevalence of non-heterosexual orientation and any PE was 7.1% and 5.5%, respectively. After adjusting for sex, age, and ethnicity, non-heterosexual orientation was positively associated with any PE (odds ratio 1.99, 95% confidence interval 1.34-2.93). The strongest mediators involved in this relationship were borderline personality disorder (BPD) traits (mediated percentage = 33.5%), loneliness (29.1%), and stressful life events (25.4%). CONCLUSIONS: These findings suggest that there is a positive relationship between sexual orientation and PEs in the general population in England, and that underlying mechanisms may involve BPD traits, loneliness, and stressful life events. Future studies with a longitudinal design are warranted to shed more light on how these factors are implicated in the association between sexual orientation and PEs.

Association between food insecurity and depression among older adults from low- and middle-income countries.

BACKGROUND: To examine the association between self-reported food insecurity and depression in 34,129 individuals aged ≥50 years from six low- and middle-income countries (LMICs) (China, Ghana, India, Mexico, Russia, and South Africa). METHODS: Cross-sectional, community-based, nationally representative data from the WHO Study on global AGEing and adult health (SAGE) were analyzed. Self-reported past 12-month food insecurity was assessed with two questions on frequency of eating less and hunger due to lack of food. Questions based on the World Mental Health Survey version of the Composite International Diagnostic Interview were used for the endorsement of past 12-month DSM-IV depression. Multivariable logistic regression analysis and meta-analysis were conducted to assess associations. RESULTS: In total, 34,129 individuals aged ≥50 years [mean (SD) age, 62.4 (16.0) years; 52.1% females] were included in the analysis. Overall, the prevalence of moderate and severe food insecurity was 6.7% and 5.1%, respectively, while the prevalence of depression was 6.0%. Meta-analyses based on countrywise estimates showed that overall, moderate food insecurity (vs. no food insecurity) is associated with a nonsignificant 1.69 (95% confidence interval [CI] = 0.82-3.48) times higher odds for depression, while severe food insecurity is significantly associated with 2.43 (95% CI = 1.65-3.57) times higher odds for depression. CONCLUSIONS: In this large representative sample of older adults from six LMICs, those with severe food insecurity were over two times more likely to suffer from depression (compared with no food insecurity). Utilizing lay health counselors and psychological interventions may be effective mechanisms to reduce depression among food-insecure populations. Interventions to address food insecurity (e.g., supplemental nutrition programs) may reduce depression at the population level but future longitudinal studies are warranted.

Sexual Orientation and Functional Limitations: Cross-sectional Analyses From the Adult Psychiatric Morbidity Survey.

OBJECTIVE: To assess the association between sexual orientation and functional limitations in a large representative sample of the English population. DESIGN: Cross-sectional. SETTING: Data were from the 2007 Adult Psychiatric Morbidity Survey. PARTICIPANTS: A total of 7403 adults aged 16-95 years (51.4% female; mean age, 46.3±18.6y) were included in the present study. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Sexual orientation was assessed using 2 items adapted from the Kinsey scale and was dichotomized into heterosexual and sexual minority orientation. Functional limitations were assessed using 7 activities of daily living (ADL) and instrumental activities of daily living (IADL). Functional limitations were defined as at least 1 difficulty in 1 of 7 ADL and IADL. Adjusted logistic regression analyses were conducted to investigate the association between sexual orientation (independent variable) and functional limitations (dependent variable). RESULTS: The level of sexual minority orientation and prevalence of functional limitations in the sample was 7.1% and 32.9%, respectively. After adjusting for several potential confounders, sexual minority orientation was positively and significantly associated with functional limitations (odds ratio, 1.51; 95% confidence interval, 1.18-1.95; reference group: heterosexual orientation). CONCLUSIONS: Based on the findings of this study, interventions aiming to prevent against and/or manage/reduce functional limitations in sexual minorities are needed. More research is also warranted to better understand mediators (eg, obesity, cognitive complaints, psychiatric disorders) involved in the sexual orientation-functional limitation relationship.

Prevalence and correlates of body dysmorphic disorder in health club users in the presence vs absence of eating disorder symptomology.

PURPOSE: Body dysmorphic disorder (BDD) has been consistently linked with eating disorders, however studies that stratify associations between BDD in subjects with and without eating disorder symptomology are sparse. It was, therefore, the aim of this study to assess correlates of BDD (including social media use, motivations for exercise, exercise addiction, and sexuality) stratified by eating disorder symptomology. METHODS: Cross-sectional study of 1665 health club users recruited online completed a battery of surveys. BDD prevalence rates were calculated and logistic regression models were created in two sub-samples: indicated or no-indicated eating disorder symptomology. RESULTS: The key findings showed the prevalence of BDD in participants with indicated-eating disorder symptomology was significantly higher than in participants without indicated-eating disorder symptomology, yielding an odds ratio of 12.23. Furthermore, several correlates were associated with BDD only participants with an absence of eating disorder symptomology (gender, BMI, exercise addiction, exercising for mood improvement, attractiveness and tone), with others being significantly associated with BDD in participants in the presence of indicated eating disorders symptomology (exercising for health and enjoyment, relationship status, and ethnicity). CONCLUSIONS: This study provides more evidence of the complex relationship that exists between BDD and eating disorders. Furthermore, it is recommended that practitioners working with BDD subjects should screen for eating disorders due to the high morbidity associated with eating disorders. LEVEL OF EVIDENCE: Level III: case-control analytic study.

Human Immunodeficiency Virus Infection and Diverse Physical Health Outcomes: An Umbrella Review of Meta-analyses of Observational Studies.

BACKGROUND: Our aim was to assess both the credibility and strength of evidence arising from systematic reviews with meta-analyses of observational studies and physical health outcomes associated with human immunodeficiency virus (HIV) but not acquired immunodeficiency syndrome. METHODS: We performed an umbrella review of observational studies. Evidence was graded as convincing, highly suggestive, suggestive, weak, or nonsignificant. RESULTS: From 3413 studies returned, 20 were included, covering 55 health outcomes. Median number of participants was 18 743 (range 403-225 000 000). Overall, 45 (81.8%) of the 55 unique outcomes reported nominally significant summary results (P < .05). Only 5 outcomes (9.0%; higher likelihood of presence of breathlessness, higher chronic obstructive pulmonary disease [COPD] prevalence, maternal sepsis, higher risk of anemia, and higher risk of all fractures among people living with HIV [PLWHIV]) showed suggestive evidence, with P values < 10-3; only 3 (5.5%; higher prevalence of cough in cross-sectional studies, higher incidence of pregnancy-related mortality, and higher incidence of ischemic heart disease among PLWHIV in cohort studies) outcomes showed stronger evidence using a stringent P value (<10-6). None of the unique outcomes presented convincing evidence (Class I), yet 3 outcomes presented highly suggestive evidence, 5 outcomes presented suggestive evidence, and 37 outcomes presented weak evidence. CONCLUSIONS: Results show highly suggestive and suggestive evidence for HIV and the presence of a cough, COPD, ischemic heart disease, pregnancy-related mortality, maternal sepsis, and bone fractures. Public health policies should reflect and accommodate these changes, especially in light of the increases in the life expectancy and the incidence of comorbidities in this population.

Associations between body mass index, waist circumference and erectile dysfunction: a systematic review and META-analysis.

Growing evidence reports that obesity might play a role in erectile dysfunction (ED), but limited knowledge is available. We conducted a meta-analysis to estimate the prevalence of ED in overweight men and men with obesity. We performed a systematic review up to 01/04/2019 to investigate the associations between obesity and ED. Applying a random-effect model, we calculated the prevalence of ED, the odds ratio (OR) for the presence of ED by Body Mass Index (BMI) categories and the mean differences between ED and controls in BMI and Waist Circumference (WC). Among 3409 studies, we included 45 articles with 42,489 men (mean age = 55 years). Taking normal weight men as reference, the prevalence of ED was significantly higher in overweight (OR = 1.31; 95%CI: 1.13-1.51; I2 = 72%) and in men with obesity (OR = 1.60; 95%CI: 1.29-1.98; I2 = 79%). Adjusting our analyses for potential confounders, the results were confirmed in men with obesity (OR = 1.46; 95%CI: 1.24-1.72; I2 = 72%). ED was associated with significant higher values of BMI (MD = 0.769; 95%CI: 0.565-0.973 Kg/m2; I2 = 78%) and WC (MD = 5.251 cm; 95%CI: 1.295-9.208; I2 = 96%). Considering the high prevalence of ED among men with obesity, clinicians should screen for this clinical condition in this population. Findings from the present study suggest that reducing adiposity is a crucial approach in patients with ED who are affected by obesity.

Challenges in the Practice of Sexual Medicine in the Time of COVID-19 in the United Kingdom.

BACKGROUND: On 23rd March 2020, the UK government released self-isolation/social distancing guidance to reduce the risk of transmission of SARS-CoV-2. The influence such guidance has on sexual activity is not known. AIM: To investigate levels and correlates of sexual activity during COVID-19 self-isolation/social distancing in a sample of the UK public. METHODS: This paper presents preplanned interim analyses of data from a cross-sectional epidemiological study, administered through an online survey. OUTCOMES: Sexual activity was measured using the following question: "On average after self-isolating how many times have you engaged in sexual activity weekly?" Demographic and clinical data were collected, including sex, age, marital status, employment, annual household income, region, current smoking status, current alcohol consumption, number of chronic physical conditions, number of chronic psychiatric conditions, any physical symptom experienced during self-isolation, and number of days of self-isolation/social distancing. The association between several factors (independent variables) and sexual activity (dependent variable) was studied using a multivariable logistic regression model. RESULTS: 868 individuals were included in this study. There were 63.1% of women, and 21.8% of adults who were aged between 25 and 34 years. During self-isolation/social distancing, 39.9% of the population reported engaging in sexual activity at least once per week. Variables significantly associated with sexual activity (dependent variable) were being male, a younger age, being married or in a domestic partnership, consuming alcohol, and a higher number of days of self-isolation/social distancing. CLINICAL IMPLICATIONS: In this sample of 868 UK adults self-isolating owing to the COVID-19 pandemic, the prevalence of sexual activity was lower than 40%. Those reporting particularly low levels of sexual activity included females, older adults, those not married, and those who abstain from alcohol consumption. STRENGTH AND LIMITATIONS: This is the first study to investigate sexual activity during the UK COVID-19 self-isolation/social distancing. Participants were asked to self-report their sexual activity potentially introducing self-reporting bias into the findings. Second, analyses were cross-sectional and thus it is not possible to determine trajectories of sexual activity during the current pandemic. CONCLUSION: Interventions to promote health and well-being during the COVID-19 pandemic should consider positive sexual health messages in mitigating the detrimental health consequences in relation to self-isolation/social distancing and should target those with the lowest levels of sexual activity.

Associations Among Physical Activity, Sedentary Behavior, and Weight Status With Sexuality Outcomes: Analyses from National Health and Nutrition Examination Survey.

INTRODUCTION: Physical activity is likely to be associated with sexual activity. However, to date, there is no literature on the relationship between overweight/obesity and sexual activity outcomes. AIM: Thus, the present study assessed the associations among physical activity, sedentary behavior, and weight status with sexual activity and number of previous sexual partners in a representative sample of U.S. adults. METHODS: Data on leisure time physical activity, total sitting time, weight status, sexual behavior outcomes, and other characteristics were extracted from the National Health and Nutrition Study cycle 2007 to 2016. Logistic regression models were used to evaluate associations among body mass index, leisure time physical activity, and total sitting time with past-year sexual activity and number of sexual partners. MAIN OUTCOME MEASURE: Self reported frequency of past-year sexual activity and number of sex partners in the past year. RESULTS: In a sample of 7,049 men (mean age: 38.3 ± 0.3 years) and 7,005 women (mean age: 38.7 ± 0.2 years) being overweight was associated with higher odds of frequent sexual activity (OR = 1.5; 95% CI = 1.2-1.7) among men, but lower odds among women (OR = 0.8; 95% CI = 0.6-0.9). Sufficient physical activity was associated with higher odds of frequent sexual activity among both men (OR = 1.3; 95% CI = 1.1-1.5) and women (OR = 1.2; 95% CI = 1.0-1.4). In those living alone, being obese was associated with lower odds of having at least 1 sexual partner for men (OR = 0.7; 95% CI = 0.5-0.9) and women (OR = 0.6; 95% CI = 0.4-0.8). Being sufficiently physically active was associated with higher odds of having at least 1 sexual partner only in men (OR = 1.6; 95% CI = 1.2-2.2). CLINICAL IMPLICATIONS: Healthcare professionals need to be made aware of these results, as they could be used to plan tailored interventions. STRENGTHS & LIMITATIONS: Strengths include the large, representative sample of U.S. adults and objective measures of anthropometry. Limitations include the cross-sectional design of the study and that all variables on sexual history were self-reported. CONCLUSION: The present study identifies novel modifiable behavioral and biological antecedents of sexuality outcomes. Grabovac I, Cao C, Haider S, et al.

Bullying Victimization and Sexual Behavior Among Adolescents Aged 12-15 Years From 53 Countries: A Global Perspective.

BACKGROUND: Identifying correlates of sexual behavior among young adolescents is critical for preventing adverse outcomes linked to such behavior. AIM: This study examined the relationship of bullying victimization with sexual intercourse, multiple sexual partners, and non-condom use in adolescents aged 12-15 years across 53 countries. METHODS: Cross-sectional data from 145,342 adolescents aged 12-15 years participating in the Global School-based Student Health Survey 2003-2016 were analyzed. Data on bullying victimization were assessed by the question "During the past 30 days, on how many days were you bullied?" OUTCOMES: Data on several sexual behaviors were collected: (i) ever having had intercourse, among those who reported having had intercourse; (ii) multiple (≥2) lifetime sexual partners; and (iii) condom use in last sexual intercourse. RESULTS: Multivariable logistic regression analyses were used to assess the associations. The overall prevalence of any bullying in the past 30 days and lifetime sexual intercourse were 28.8% and 13.1%, respectively. Compared with those who were not bullied in the past 30 days, those who were bullied for 20-30 days were 2.08 (95% CI = 1.65-2.63), 1.70 (95% CI = 1.10-2.63), and 1.72 (95% CI = 1.12-2.67) times more likely to report sexual intercourse, non-condom use, and multiple sex partners, respectively. CLINICAL IMPLICATIONS: This study provides further evidence that bullying victimization is a global phenomenon and interventions are required to reduce its prevalence and unwanted consequences. STRENGTHS & LIMITATIONS: The main strength was the large sample of young adolescents across 53 countries. However, findings from the present study should be interpreted in light of its limitations. First, the study was cross-sectional in nature and thus the direction of the association cannot be established. Second, the data only included young adolescents who attend school. Third, data were self-reported and thus reporting bias may exist. Fourth, the measure of sexual activity used was not able to distinguish between penetrative and nonpenetrative sex. Fifth, adolescents who are victims of bullying may also be exposed to other types of violence such as child maltreatment and sexual assaults, for which data were not available. Finally, the present data set did not contain data on sexual orientation. CONCLUSION: These findings highlight the need for interventions either acting to educate about the potential negative consequences or to prevent risky sexual behavior in young adolescents who experience bullying victimization.

Trends in Sexual Activity and Associations With All-Cause and Cause-Specific Mortality Among US Adults.

BACKGROUND: Sexual activity can be referred to as a health behavior and may also act as an indicator of health status. AIM: To evaluate temporal trends in sexual activity and to examine associations of sexual activity with all-cause and cause-specific mortality risk. METHODS: We examined the trends and prevalence of sexual activity and association of sexual activity with all-cause and cause-specific mortality in a nationally representative sample using data from the US National Health and Nutrition Examination Survey from 2005 to 2016 and the National Health and Nutrition Examination Survey 2005-2014 Linked Mortality File (through December 31, 2015). OUTCOMES: All-cause, cardiovascular disease, and cancer mortality. RESULTS: A total of 15,269 US adults (mean age, 39.1 years [standard error, 0.18 years]) were included in the trend analysis. In the 2015-2016 cycle, while 71.7% (95% CI, 67.7-75.7%) US adults aged 20-59 years engaged in sexual activity ≥ 12 times/year (monthly), only 36.1% (95% CI, 31.6-40.7%) of them engaged in sexual activity ≥ 52 times/year (weekly). Since the 2005-2006 cycle, the estimated prevalence of sexual activity, ≥52 times/year and ≥12 times/year, were both stable over time among overall and each age group (all P for trend >0.1). During a median follow-up of 5.7 years (range, 1-11 years) and 71,960 person-years of observation, among 12,598 participants with eligible information on mortality status, 228 deaths occurred, including 29 associated with cardiovascular disease and 62 associated with cancer. Overall, participants with higher sexual activity frequency were at a lower risk of all-cause death in a dose-response manner (P for trend = 0.020) during the follow-up period. In addition, the multivariable-adjusted hazard ratios for all-cause mortality, CVD mortality, cancer mortality, and other cause mortality among participants who had sex ≥52 times/year compared with those having sex 0-1 time/year were 0.51 (95% CI, 0.34 to 0.76), 0.79 (95% CI, 0.19 to 3.21), 0.31 (95% CI, 0.11 to 0.84), and 0.52 (95% CI, 0.28 to 0.96), respectively. CLINICAL IMPLICATIONS: Sexual activity appears to be a health indicator of all-cause and cancer mortality in US middle-aged adults. STRENGTHS & LIMITATIONS: Clear strengths of the present study include the large representative sample of the noninstitutionalized US population as well as the identification of precise estimates in relation to sexual activity and mortality. However, because of the observational nature of the study design, causality could not be determined. CONCLUSIONS: Sexual activity was found to be associated with a lower risk of mortality from all cause and cancer. Cao C, Yang L, Xu T, et al. Trends in Sexual Activity and Associations With All-Cause and Cause-Specific Mortality Among US Adults. J Sex Med 2020;17:1903-1913.

Sexual activity and cognitive decline in older age: a prospective cohort study.

BACKGROUND: To explore the association between sexual activity and change in cognitive function over 4 years in a representative sample of older adults in England. METHODS: Data were from 1963 men and 2513 women participating in Wave 6 (2012/2013) and Wave 8 (2016/2017) of the English Longitudinal Study of Ageing. Participants reported whether or not they had engaged in any sexual activity in the last year. Cognitive function was assessed with tests of immediate and delayed recall. Adjusted general linear models were used to test associations between sexual activity and changes in cognitive function. RESULTS: Men who were sexually active at baseline had better preservation in immediate (0.18 points, 95% CI 0.07-0.29, p = 0.002) and delayed recall (0.19 points, 95% CI 0.08-0.29, p = 0.001) over 4-year follow-up. No significant associations were observed for women. DISCUSSION: Strengths of this study include large, representative sample, longitudinal design and adjustment for a wide range of potential confounders. The observational nature of our study means we cannot deduce the exact direction of effect of our findings. In addition, cognitive ability test scores in older people may reflect not only a possible decline, but also their peak prior cognitive ability; but we did not have any information regarding the trajectories of their cognitive function during the lifespan. CONCLUSION: Health practitioners should be encouraged to screen older men relating to their sexual activity to identify those who may be at risk of cognitive decline. Older men will be heartened to know that sexual activity may aid in the prevention of age-related decline in cognition.

Leisure-Time Sedentary Behavior, Alcohol Consumption, and Sexual Intercourse Among Adolescents Aged 12-15 Years in 19 Countries From Africa, the Americas, and Asia.

BACKGROUND: The association between sedentary behavior and sexual behavior has not been investigated among adolescents. AIM: The aim of this study was to: (i) investigate the association between leisure-time sedentary behavior and sexual intercourse, and (ii) test for mediation by alcohol consumption, drug use, physical activity, bullying victimization, parental support/monitoring, loneliness, and depressive symptoms in a large global sample of young adolescents. METHODS: Data were analyzed from 34,674 adolescents aged 12-15 years participating in the Global School-based Student Health Survey. Participants reported the number of hours spent in leisure-time sedentary behavior on a typical day (<1, 1-2, 3-4, 5-8, and >8 hours). Data on alcohol consumption, drug use, physical activity, bullying victimization, parental support/monitoring, loneliness, and depressive symptoms were considered as potential mediators. OUTCOME: Participants reported whether or not they had sexual intercourse in the past 12 months (yes/no). RESULTS: The prevalence of past 12-month sexual intercourse was 11.9%, whereas the prevalence of <1, 1-2, 3-4, 5-8, and >8 hours per day of leisure-time sedentary behavior were 26.7%, 35.6%, 21.4%, 11.5%, and 4.9%, respectively. There was a dose-dependent relationship between sedentary behavior and odds of reporting sexual intercourse: compared with <1 hour/day of sedentary behavior, the odds ratio (95% CI) of sexual intercourse associated with 1-2, 3-4, 5-8, and >8 hours/day of sedentary behavior were 1.12 (0.94-1.33), 1.22 (1.01-1.48), 1.34 (1.08-1.66), and 1.76 (1.37-2.27), respectively. There was no significant interaction by sex. The largest proportion of the association between sedentary behavior and sexual intercourse was explained by alcohol use (% mediated 21.2%), with other factors explaining an additional 11.2%. CLINICAL TRANSLATION: Interventions to reduce leisure-time sedentary and/or alcohol consumption may contribute to a reduction in the proportion of adolescents engaging in sexual intercourse at a young age. The strengths and limitations of this study are the large, representative sample of adolescents from 19 countries. However, the cross-sectional design means causality or temporal associations could not be established. CONCLUSIONS: In young adolescents, leisure-time sedentary behavior is positively associated with odds of having sexual intercourse in both boys and girls, in a dose-dependent manner. Alcohol consumption seems to be a key mediator of this relationship. Smith L, Jackson SE, Jacob L, et al. Leisure-Time Sedentary Behavior, Alcohol Consumption, and Sexual Intercourse Among Adolescents Aged 12-15 Years in 19 Countries From Africa, the Americas, and Asia. J Sex Med 2019;16:1355-1363.

Tackling bisexual erasure: An explorative comparison of bisexual, gay and straight cisgender men's body image.

Previous body image research often grouped both gay and bisexual men into a single category: sexual minoritised men, limiting our understanding of how sexual identity influences body image. However, there is strong reason to believe that bisexual and gay men experience distinct body image concerns. Here, we explored motivations to alter one's leanness and muscularity, as well as (dis)satisfaction with body fat, muscularity, height and penis size, and functionality appreciation across gay, bisexual, and straight cisgender men. We sampled 378 white participants aged 18 to 85 (nbisexual = 125, ngay = 128, nstraight = 125). We found that bisexual men were significantly less motivated to be lean and showed lower muscularity dissatisfaction relative to gay men but showed comparable levels to straight men. Our findings demonstrate that despite research perceiving the body image of bisexual and gay men as homogenous, they experience differences in their body image concerning leanness and muscularity dissatisfaction. Future body image research should incorporate this understanding by not artificially grouping bisexual and gay cisgender men and instead acknowledging the potential uniqueness in their experiences.

Global Trends in the Prevalence of Alcohol Consumption Among School-Going Adolescents Aged 12-15 Years.

PURPOSE: Adolescent alcohol consumption is detrimental to multiple facets of health. However, there is a scarcity of data available on time trends in adolescents' alcohol consumption particularly from non-Western countries and low- and middle-income countries. Thus, we examined the temporal trend of alcohol use in a large representative sample of school-going adolescents aged 12-15 years from 22 countries in Africa, Asia, and the Americas. METHODS: Data from the Global School-based Student Health Survey were analyzed. Alcohol consumption referred to consuming alcohol on at least one day in the past 30 days. Crude linear trends of past 30-day alcohol consumption by country were assessed by linear regression models. RESULTS: Data on 135,426 adolescents aged 12-15 years were analyzed [mean (standard deviation) age 13.8 (1.0) years; 52.0% females]. The overall mean prevalence of past 30-day alcohol consumption was 14.1%. Of the 22 countries included in the study, increasing, decreasing, and stable trends were observed in 3, 8, and 11 countries, respectively. Specifically, significant increases were observed in Benin between 2009 (16.1%) and 2016 (38.6%), Myanmar between 2007 (0.9%) and 2016 (3.6%), and Vanuatu between 2011 (7.6%) and 2016 (12.2%). The most drastic decrease was observed in Samoa between 2011 (34.5%) and 2017 (9.8%), but the rate of decrease was modest in most countries. DISCUSSION: Among school-going adolescents, decreasing trends in alcohol consumption were more common than increasing trends, but the rate of decrease was limited in most countries, suggesting that more global action is required to curb adolescent alcohol consumption.

Assessing Attitudes Toward Trans and Gender Diverse People: Adapting the 'Transgender Attitudes and Beliefs' Scale.

This study aimed to update the gender-based terminology of a measure used to assess attitudes toward trans and gender diverse people (the Transgender Attitudes and Beliefs Scale; TABS) in order to reflect appropriate and inclusive language standards and conventions while maintaining the psychometric integrity of the tool. The updated TABS was administered to 247 heterosexual, cisgender adults in the UK. Participants also completed the original TABS as well as measure of self-esteem and social desirability to test construct validity. We demonstrate that after updating the language of the TABS to reflect best-practice, the psychometric properties of the TABS were unaffected.

Characteristics and Effectiveness of Co-Designed Mental Health Interventions in Primary Care for People Experiencing Homelessness: A Systematic Review.

People experiencing homelessness (PEH) face a disproportionately high prevalence of adverse mental health outcomes compared with the non-homeless population and are known to utilize primary healthcare services less frequently while seeking help in emergency care facilities. Given that primary health services are more efficient and cost-saving, services with a focus on mental health that are co-designed with the participation of users can tackle this problem. Hence, we aimed to synthesize the current evidence of such interventions to assess and summarize the characteristics and effectiveness of co-designed primary mental healthcare services geared towards adult PEH. Out of a total of 10,428 identified records, four articles were found to be eligible to be included in this review. Our findings show that co-designed interventions positively impacted PEH's mental health and housing situation or reduced hospital and emergency department admissions and increased primary care utilization. Therefore, co-designed mental health interventions appear a promising way of providing PEH with continued access to primary mental healthcare. However, as co-designed mental health interventions for PEH can improve overall mental health, quality of life, housing, and acute service utilization, more research is needed.
