Risk factors associated with resistance to HIV testing among transwomen in Brazil.

Transwomen are a high-risk population for HIV/AIDS worldwide. However, many transwomen do not test for HIV. This study aimed to identify factors associated with resistance to HIV testing among transwomen in Fortaleza/CE. A cross-sectional study was conducted between August and December 2008 with a sample of 304 transwomen recruited through respondent-driven sampling. Data analysis utilized Respondent-Driven Sampling Analysis Tool and SPSS 11.0. Univariate, bivariate, and multivariate analyses examined risk factors associated with resistance to HIV testing. Less than 18 years of age (OR = 4.221; CI = 2.419-7.364), sexual debut before 10 years of age (OR = 6.760; CI = 2.996-15.256), using illegal drugs during sex (OR = 2.384; CI = 1.310-4.339), experience of discrimination (OR = 3.962; CI = 1.540-10.195) and a belief that the test results were not confidential (OR = 3.763; CI = 2.118-6.688) are independently associated with resistance to testing. Intersectoral and targeted strategies aimed at encouraging the adoption of safer sexual behaviors and testing for HIV among transwomen are required.

Relevance of anxiety and stress levels on sleep quality after liver transplantation.

The goal of this study was to assess the effects of anxiety and stress on sleep quality in liver transplantation recipients. A prospective cross-sectional study was performed including 45 recipients enrolled at a liver transplantation program at Ribeirão Preto, State of São Paulo, Brazil. Anxiety and stress were evaluated by using a reduced version of the State-Trait Anxiety Inventory and the Perceived Stress Scale, respectively. Sleep quality and excessive daytime sleepiness were evaluated by using the Brazilian Portuguese versions of the Pittsburgh Sleep Quality Index and the Epworth Sleepiness Scale. Thirty-two (71.11%) recipients presented with compromised sleep quality and 5 (11.11%) presented with excessive daytime sleepiness. Recipients with bad sleep quality had anxiety (mean, 26.91 points) and stress (mean, 17.88 points) levels that were higher than the levels of patients with normal sleep quality patterns, with anxiety levels presenting with statistically significant differences (P = .0420). Patients with above-average stress levels also had increased anxiety (mean, 28 points) and compromised sleep quality (mean, 7.03 points). In conclusion, a liver transplantation recipient who experiences bad sleep quality also has higher levels of anxiety and stress, suggesting a relationship between the sleep-wakefulness cycle and anxiety/stress. Planning strategies aimed at reducing such emotional shifts among recipients is of paramount importance. Therefore, new strategies focusing on improving the sleep pattern of patients are necessary because unhealthy sleep behavior may impair postoperative recovery.

Self-reported sexual behaviour and HIV risk taking among men who have sex with men in Fortaleza, Brazil.

OBJECTIVES: To describe and identify sociodemographic and behavioural characteristics and other factors related to high-risk behaviour for HIV infection of men who have sex with men (MSM) living in Fortaleza, Brazil. METHODS: A survey was carried out among 400 MSM aged 14-65 years and recruited through the snowball technique or in gay-identified venues. A semi-structured questionnaire was conducted among them. Logistic regression analysis was used to model the dichotomous outcome (high risk or low risk). RESULTS: Forty-four per cent of the participants reported engaging in high-risk sexual behaviour in the previous year. MSM less informed about AIDS, reporting more sexual partners, reporting at least one female partner in the previous year, having anal sex as the favourite way to have sex, and having great enjoyment of unprotected anal sex were more likely to be engaged in risky behaviour. Twenty-three per cent of participants reported at least one sexual contact with women during the previous year. Two-thirds of men who had unprotected sex with their female partners also had unprotected anal sex with their male partners. CONCLUSIONS: A large proportion of MSM in Fortaleza still remain at elevated risk for contracting HIV infection. The factors predictive of high-risk sexual behaviour are significant in spreading HIV infection among the MSM population and also among their female partners. The lifestyles of these men are different to those of men from other parts of Brazil or outside the country. Preventive interventions need to be culturally and socially specific in order to be effective.
