Abstract

Research on male clients of male sex workers (MCMSW) has been neglected for a long time globally. We aimed to characterize MCMSW and to identify factors associated with their sexual practices using data from the prospective cohort study CohMSM conducted in Burkina Faso, Cote dIvoire, Mali and Togo. Our study focused on HIV-negative men who have sex with other men (MSM) recruited between 06/2015 and 01/2018 by a team of trained peer educators. Scheduled study visits at 6, 12 and 18 months included medical examinations, HIV screening, risk-reduction counselling and face-to-face interviews to collect information on their sociodemographic characteristics, sexual behaviours, and HIV risk-reduction strategies (HIV-RRS). Three stigmatization sub-scores were constructed (experienced, perceived and internalized). Mixed-effects logistic regression was used for data analysis. Of the 280 participants recruited at baseline, 238, 211 and 118, respectively, had a follow-up visit at 6, 12 and 18 months. Over a total of 847 visits, 47 transactional sex (TS) encounters were reported by 38 MCMSW (13.6%). Of the latter, only one participant reported systematic TS (2.6%), 18 (47.4 %) stopped reporting TS after baseline, and 6 (15.8%) reported TS after baseline. Thirteen participants (34.2 %) reported occasional TS. After adjusting for country of study and age, the following self-reported factors were associated with a greater likelihood of being MCMSW: protected anal sex, exclusively insertive anal sex with male sexual partners, avoidance of sex after consuming psychoactive products and experiencing stigmatization (all during the previous 6 months). The majority of MCMSW in this study employed HIV-RRS with male sexual partners, including engaging in protected anal sex, avoidance of sex when consuming psychoactive products, and practising exclusively insertive anal sex.

The Relationship between Body Mass Index and Poor Self-Rated Health in the Korean Population

ObjectiveSeveral previous studies have evaluated associations between body mass index (BMI) and self-rated health (SRH); however, the results were inconsistent. This study aimed to examine the association between BMI and SRH in Korean adults.\n\nMethodsThe study was conducted in 214,997 adults who participated in the 2016 Korean Community Health Survey. Participants were categorized into four groups based on BMI: underweight (<18.5 kg/m2), normal weight (18.5-24.9 kg/m2), overweight (25.0-29.9 kg/m2), or obese ([≥]30.0 kg/m2). Multivariate Poisson regression analysis with sampling weights and robust variance estimators was performed to evaluate the relationship between BMI categories and poor SRH.\n\nResultsThere was a J-shaped association between BMI and poor SRH in both sexes, with the lowest risk observed in the normal weight group in both sexes. Compared with normal weight subjects, the age and lifestyle adjusted prevalence rate ratios for poor SRH were 1.61 (95% CI, 1.50-1.74) for underweight, 1.16 (95% CI, 1.11-1.21) for overweight, and 2.35 (95% CI, 2.13-2.58) for obese men; and 1.24 (95% CI, 1.17-1.32) for underweight, 1.26 (95% CI, 1.22-1.31) for overweight, and 1.77 (95% CI, 1.64-1.91) for obese women.\n\nConclusionsIn a cross-sectional study using a nationally representative survey, there was a nonlinear relationship between BMI and poor SRH. This relationship was more prominent in men than in women. Prospective studies are needed to further clarify the relationship between BMI and SRH.

Seroprevalence of human Brucellosis and associated risk factors among high risk occupations in Mbeya Region of Tanzania

BackgroundBrucellosis is an infectious zoonotic disease that affects humans, livestock and wildlife.\n\nMethodsA cross-sectional study was conducted in Mbeya region between November 2015 and January 2016 to investigate the seroprevalence of human brucellosis and identify associated risk factors among individuals in risky occupations in Mbeya Region. A total of 425 humans from six occupational categories were serially tested for Brucella antibodies using the Rose Bengal Plate Test (RBPT) and competitive Enzyme Linked Immunosorbent Assay (c-ELISA), for screening and confirmation, respectively. A questionnaire survey was administered to participants collect epidemiological data.\n\nResultsThe overall seroprevalence among the high risk occupational individuals was 1.41% (95% CI: 0.01-0.03). Seroprevalence among the different occupations were as follows: shepherds 1.33% (95% CI: 0.14-0.22); butcher men 5.26% (95% CI: 0.10-0.17) and abattoir workers 1.08% (95% CI: 0.39-0.49). Seroprevalence was noted to vary according to occupation type, milk consumption behaviour, age and sex. Butcher men recorded the highest seroprevalence (5.0%) while individuals who consumed unboiled milk had a higher seroprevalence (1.56%) compared to those who drunk boiled milk. High seropositivity (2.25%) was observed among the age group of 1-10 years while male individuals had a higher seroprevalence (1.41%) than females (0%). Butcher men were at higher risk of exposure compared to other professions.\n\nConclusionOur findings show the presence of brucellosis in occupationally exposed individuals in Mbeya region. There is need to sensitize the exposed individuals in order to reduce the risk of acquiring Brucella infections from animals and animal products This also calls for public health awareness about the disease, and implementation of control measures that will prevent further spread of brucellosis within and outside the study area..\n\nAuthor summaryBrucellosis is a bacterial zoonosis that has evolved to establish itself as an occupational and food-borne disease Worldwide. It is responsible for huge economic losses incurred by livestock keepers and poses a public health risk to humans in most developing countries. In Tanzania, which has the 3rd highest cattle population in Africa, many studies that have been done show that brucellosis exists in livestock, especially in cattle and wildlife. However, very few studies have reported on human brucellosis. The disease has been reported to occur in humans who have direct exposure to cattle or cattle products like livestock farmers, abattoir workers, veterinarians, shepherds and farm workers in many developing countries. A few studies in Tanzania have reported seroprevalences among these high-risk occupations; however, the disease has not been fully described in Mbeya region. This study was therefore aimed at filling these information gaps and contributing to the existing body of knowledge.

Development of equations for converting random-zero to automated oscillometric blood pressure values

ObjectiveThis study aimed to collect data to compare blood pressure values between random-zero sphygmomanometers and automated oscillometric devices and generate equations to convert blood pressure values from one device to the other.\n\nMethodsOmron HEM-907, a widely used automated oscillometric device in many epidemiologic surveys and cohort studies, was compared here with random-zero sphygmomanometers. Two hundred and one participants aged 40-79 years (37% men) were enrolled and randomly assigned to one of two groups with blood pressure measurement first taken by automated oscillometric devices or by random-zero sphygmomanometers. The study design enabled comparisons of blood pressure values between random-zero sphygmomanometers and two modes of this automated oscillometric device - automated and manual, and assessment of effects of measurement order on blood pressure values.\n\nResultsAmong all participants, mean blood pressure levels were lowest when measured with random-zero sphygmomanometers compared with both modes of automated oscillometric devices. Several variables, including age and gender, were found to contribute to the blood pressure differences between random-zero sphygmomanometers and automated oscillometric devices. Equations were developed using multiple linear regression after taking those variables into account to convert blood pressure values by random-zero sphygmomanometers to automated oscillometric devices.\n\nConclusionEquations developed in this study could be used to compare blood pressure values between epidemiologic and clinical studies or identify shift of blood pressure distribution over time using different devices for blood pressure measurements.
