Virtually 'in the heat of the moment': insula activation in safe sex negotiation among risky men.

ABSTRACT: HIV is most prevalent among men who have sex with men (MSM), and although most MSM use condoms consistently during casual sex, some take risks. To better understand the psychology of those risky decisions, we examined neural correlates of playing a virtual sexual 'hook up' game in an functional magnetic resonance imaging scanner in MSM who had, in the past 90?days, been sexually risky (N?=?76) or safe (N?=?31). We found that during potentially risky sexual choices, previously risky MSM had more right insula activity than previously safe MSM. Real-life sexual risk was related to trait positive and negative urgency. Insula activity that differentiated risky and safe MSM was related to trait positive and negative urgency. Future work should further examine if, and to what extent, insula activation during safe sex negotiation drives MSM's rash risky sexual decision-making.

Project description:BackgroundAfter a neurological injury, mobility focused rehabilitation programs intensively train walking on treadmills or overground. However, after discharge, quite a few patients are not able to independently negotiate stairs, a real-world task with high physical and psychological demands and a high injury risk. To decrease fall risk and improve patients' capacity to navigate typical environments, early stair negotiation training can help restore competence and confidence in safe stair negotiation. One way to enable early training in a safe and permissive environment is to unload the patient with a body weight support system. We here investigated if unloaded stair negotiation complies with basic locomotor principles, in terms of enabling performance of a physiological movement pattern with minimal compensation.MethodsSeventeen able-bodied participants were unloaded with 0-50% bodyweight during self-paced ascent and descent of a 4-tread staircase. Spatio-temporal parameters, joint ranges of motion, ground reaction forces and myoelectric activity in the main lower limb muscles of participants were compared between unloading levels. Likelihood ratio tests of separated linear mixed models of the investigated outcomes assessed if unloading affects the parameters in general. Subsequent post-hoc testing revealed which levels of unloading differed from unsupported stair negotiation.ResultsUnloading affected walking velocity, joint ranges of motion, vertical ground reaction force parameters and myoelectric activity in all investigated muscles for stair ascent and descent while step width and single support duration were only affected during ascent. A reduction with increasing levels of body weight support was seen in walking velocity (0.07-0.12 m/s), ranges of motion of the knee and hip (2-10°), vertical ground reaction force peaks (10-70%) and myoelectric activity (17-70%). An increase with unloading was only seen during ascent for ankle range of motion and tibialis anterior activity at substantial unloading.ConclusionsBody weight support facilitates stair negotiation by providing safety and support against gravity. Although unloading effects are present in most parameters, up to 30% body weight support these changes are small, and no dysfunctional patterns are introduced. Body weight support therefore fulfills all the necessary requirements for early stair negotiation training.

Project description:BackgroundIndividuals with risk-loving attitudes may be more likely to participate in high-risk sex and gambling. We investigated whether a lottery-based financial incentive to have a negative syphilis test may attract Chinese men who have sex with men (MSM) who practised risky sexual behaviours.MethodsIn July 2018, a national online cross-sectional survey was conducted in China. We collected information on willingness to participate in a lottery-based financial incentive where men were eligible if they tested negative for syphilis, and the minimum prize that would attract them to participate. We used a validated risk attitude scale which asked about the willingness to take risks in six domains, ranging from 0 (avoids taking risk) to 10 (fully prepared to take risks). To avoid multicollinearity, we used principal components analysis to create a 'risk attitude index'. Bivariable and multivariable logistic regression explored factors associated with willingness to test negative for syphilis.Results699 MSM enrolled with a median age of 26 years (IQR: 23-30). 70% self-identified as gay and 52% reported ever testing for syphilis. 64% stated they were likely or very likely to test for syphilis linked with a lottery-based incentive. The median desired amount for the lottery had an expected value of ¥10 (US$1.50, IQR: ¥5-¥30). Men who had greater odds of willingness to participate in the lottery-based incentive were those scoring highest on the risk attitude index (adjusted OR (AOR) 2.6, 95% CI 1.5 to 4.3), those reporting more than one sexual partner in the last 3 months (AOR 1.7, 95% CI 1.2 to 2.4), those who had not used condoms during their last sex (AOR 1.5, 95% CI 1.0 to 2.2) and those who ever had group sex (AOR 1.5, 95% CI 1.0 to 2.2).ConclusionChinese MSM with higher risk attitudes and who reported riskier sexual behaviours indicated greater interest in the concept of a lottery-based incentive for syphilis testing. A lottery-based incentive may be a promising strategy for promoting condom use among risk-loving men.

Project description:BackgroundWorldwide, sexual and gender minority individuals have disproportionate burden of HIV. There are limited quantitative data from sub-Saharan Africa on the intersection of risks experienced by transgender women (TGW) in comparison to cis-men who have sex with men (MSM). This analysis addresses this gap by comparing reported stigma, psychosocial measures of health, and sexual risk practices between TGW and cis-MSM in Kenya.MethodsWe analyzed data from the baseline visit of an ongoing prospective cohort study taking place in three diverse metropolitan areas. Eligible participants were HIV-negative, assigned male at birth, ages 18-29 years, and reported anal intercourse in the past 3 months with a man or TGW. Data collected by audio computer assisted self-interview included sociodemographic measures, and sexual practices occurring in the past 3 months. Multivariable regressions assessed differences between TGW and cis-MSM in selected sexual practices, depressive symptoms, alcohol and drug use, and stigma.ResultsFrom September, 2019, through May, 2021, 838 participants were enrolled: 108 (12.9%) TGW and 730 (87.1%) cis-MSM. Adjusting for sociodemographic variables, TGW were more likely than cis-MSM to report: receptive anal intercourse (RAI; adjusted prevalence ratio [aPR] = 1.59, 95% CI: 1.32 - 1.92), engaging in group sex (aPR = 1.15, 95% CI: 1.04 - 1.27), 4 or more male sex partners (aPR = 3.31, 95% CI: 2.52 - 4.35), and 3 or more paying male sex partners (aPR = 1.58, 95% CI: 1.04 - 2.39). TGW were also more likely to report moderate to severe depressive symptoms (aPR = 1.42, 95% CI: 1.01 - 1.55), and had similar alcohol and drug abuse scores as cis-MSM. In sensitivity analysis, similar to TGW, male-identifying individuals taking feminizing gender affirming therapy had an increased likelihood of reporting RAI and group sex, and greater numbers of male sex partners and paying male sex partners relative to cis-MSM.ConclusionsAcross three metropolitan areas in Kenya, TGW were more likely to report depressive symptoms and increased sexual risk taking. We identified a need for research that better characterizes the range of gender identities. Our analysis affirms the need for programmatic gender-affirming interventions specific to transgender populations in Kenya and elsewhere in Africa.
