Recruiting people from diverse backgrounds to participate in health research requires intentional and culture-driven strategic efforts. In this study, we utilize publicly available Twitter posts to identify targeted populations to recruit for our HIV prevention study. Natural language processing methods were used to find self-declarations of ethnicity, gender, and age group, and advanced classification methods to find sexually-explicit language. Using the official Twitter API and the available tools, Demographer and M3, we identified 4800 users who were likely young Black or Hispanic men living in Los Angeles from an initial collection of 47.4 million tweets posted over 8 months. Despite a limited precision, our results suggest that it is possible to automatically identify users based on their demographic attributes and characterize their language on Twitter for enrollment into epidemiological studies.

Past evaluations of the success of wastewater treatment and submarine outfall placement and operation have considered only a limited number of parameters affecting the marine and onshore environments. Important questions regarding the best allocation of available funds have not been adequately addressed. The relative contamination of the sea from airborne and landwash contaminants has not been considered. Neither has the increased air pollution deriving from the energy required for advanced treatment. Similarly, regular epidemiological studies to evaluate actual changes in morbidity arising from drastic changes in treatment and disposal have not been made prior to very large committments of funds. Most importantly, little attention has been given to the relative ranking of all environmental risks within a catchment area. The net result is that, when all factors are considered, the very large expenditures and increased energy use for sanitary wastewater treatment and outfall disposal will have a net negative effect on the physical and societal environment. The City of Los Angeles and the Los Angeles Metropolitan area can be used to illustrate this probability.

This figure depicts the disparities in average police stops in New York City from 2004 to 2012, disaggregated by race, gender, and age. Composed of six bar charts, each graph in the figure provides data for a particular population at the intersection of race and gender, focusing on black, white, and Hispanic men and women. Each graph also has a comparative backdrop of the data on police stops for black males. All graphs take a similar parabolic shape, showing that across each race-gender group, pedestrian stops increase in adolescence and peek in young adulthood, then taper off across the adult life course. However, the heights of these parabolic representations are vastly different. There are clear disparities in police exposure based on race and gender, with black men and women being more likely than their peers to be policed and with black men being policed significantly more than their female counterparts.

BACKGROUND. Obesity by prevalence is equated to non-infectious epidemic. Conduction of epidemiological studies in different regions allows to assess the scale of the problem, to form and implement a program aimed at reducing this risk factor. AIM. To determine the prevalence of overweight and obesity in the adult population of the city of Irkutsk depending on gender and age. MATHERIALS AND METHODS. The data of the survey of a representative sample of the adult population of Irkutsk, consisting of 3510 people, are analyzed. Based on the calculated BMI, a group of respondents with an overweight and obesity was identified. RESULTS. The average age of respondents with a BMI over 25 kg/m2 was higher than average age in the population – 48 and 40 years. The prevalence of BMI over 25 kg/m2 was diagnosed in 1551 respondents (44,2%): women 47.2% of men and 40.3% of the. Overweight was found in 27.8 %, obesity at 16.4%. While being overweight were more often registered in men, 29.8% and 26.2% and obesity in women is 21% and 10.5%. CONCLUSIONS. In the adult population of Irkutsk, we found a significant prevalence of overweight and obesity and determined its sex and age characteristics.

Ehealth Intervention

BACKGROUND Black and Hispanic men who have sex with men in the United States continue to be disproportionately affected by HIV and AIDS. Uptake of and knowledge about biobehavioral HIV prevention approaches, such as treatment as prevention and preexposure prophylaxis, are especially low in these populations. eHealth campaigns and social media messaging about treatment as prevention and preexposure prophylaxis may help to fill this gap in knowledge and lead to increased uptake of such strategies; however, no evidence exists of the effects of these targeted forms of communication on treatment as prevention and preexposure prophylaxis uptake in these populations. OBJECTIVE We describe the protocol for a 3-part study aiming to develop and evaluate an eHealth intervention with information about treatment as prevention and preexposure prophylaxis for HIV-positive and HIV-negative black and Hispanic men who have sex with men. METHODS Phases 1 and 2 will involve focus groups and cognitive interviews with members of the target populations, which we will use to create a culturally tailored, interactive website and applicable social media messaging for these men. Phase 3 will be a small randomized controlled trial of the eHealth intervention, in which participants will receive guided social media messages plus the newly developed website (active arm) or the website alone (control arm), with assessments at baseline and 6 months. RESULTS Participant recruitment began in August 2017 and will end in August 2020. CONCLUSIONS Public health interventions are greatly needed to increase knowledge about and uptake of biobehavioral HIV prevention strategies such as treatment as prevention and preexposure prophylaxis among black and Hispanic men who have sex with men. eHealth communication campaigns offer a strategy for engaging these populations in health communication about biobehavioral HIV prevention.
