This paper aims to estimate the prevalence of client-perpetrated violence against female sex workers (FSWs) in Bogotá and to understand what structural and environmental factors are associated with such victimization. The project used secondary data from interviews with 2,684 FSWs. Multivariable binary logistic regression was used to test for associations with client-perpetrated violence. Findings reveal that factors such as experiencing police harassment and social stigma were positively associated with client-perpetrated violence. Situational factors such as providing services in motels, hotels, on the street, and in cars were also associated with increased odds of becoming a victim of violence., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Introduction: In the context of the COVID-19 pandemic, vaccination is considered a potentially effective strategy for controlling the disease. The objective of this study is to estimate the number of people with a high risk of morbidity and those who should be prioritized in immunization planning in Colombia., Materials and Methods: The population at risk by age was identified from the national census data of 2018. Various sources were identified to obtain information on the number of patients with different comorbidities, including heart failure, diabetes, chronic kidney failure, cancers, HIV infection, and obesity. Sources were also identified to estimate the number of health workers, teachers and military and police force personnel., Results: By 2021, Colombia is estimated to have a total of 51,049,498 inhabitants, of whom 14% will be people over 60 years of age. Additionally, of the people with comorbidities younger than 60 years old, 5,233,241 inhabitants are expected to be obese, 592,726 are expected to have diabetes mellitus, 216,389 are expected to have chronic kidney disease, and 521,263 are expected to have heart failure, totaling 15,055,697 individuals. Combining the high-priority groups and health workers, a projected 20 million people will have mortality risk factors., Conclusions: For Colombia's vaccination strategy to have an impact on reducing mortality, population groups with risk factors, corresponding to approximately 15 million inhabitants, as well as essential workers should be prioritized., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2022 Elsevier Ltd.

Background: Afghanistan, Colombia and Myanmar are the world's leading heroin and cocaine producers and have also experienced prolonged periods of armed conflict. The link between armed conflict and drug markets is well established but how conflict impacts on the health and social determinants of people who use drugs is less clear. The aim was to investigate health outcomes and associated factors among people who use illicit drugs in Afghanistan, Colombia and Myanmar. Methods: We conducted a systematic review searching Medline, EMBASE, PsychINFO and Global Health databases using terms relating to Afghanistan, Colombia and Myanmar; illicit drug use (all modes of drug administration); health and influencing factors. Quality assessment was assessed with the Newcastle–Ottawa-Scale and papers were analysed narratively. Results: 35 studies were included in Afghanistan (n = 15), Colombia (n = 9) and Myanmar (n = 11). Health outcomes focused predominantly on HIV, Hepatitis C (HCV), Hepatitis B and sexually transmitted infections (STIs), with one study looking at human rights violations (defined as maltreatment, abuse and gender inequality). Drug use was predominantly injection of heroin, often alongside use of amphetamines (Myanmar), cocaine and cocaine-based derivatives (Colombia). Only one study measured the effect of a period of conflict suggesting this was linked to increased reporting of symptoms of STIs and sharing of needles/syringes among people who inject drugs. Findings show high levels of external and internal migration, alongside low-income and unemployment across the samples. External displacement was linked to injecting drugs and reduced access to needle/syringe programmes in Afghanistan, while initiation into injecting abroad was associated with increased risk of HCV infection. Few studies focused on gender-based differences or recruited women. Living in more impoverished rural areas was associated with increased risk of HIV infection. Conclusions: More research is needed to understand the impact of armed-conflict and drug production on the health of people who use drugs. The immediate scale-up of harm reduction services in these countries is imperative to minimize transmission of HIV/HCV and address harms associated with amphetamine use and other linked health and social care needs that people who use drugs may face.

Background: Epidemiologic research among migrant populations is limited by logistical, methodological, and ethical challenges, but it is necessary for informing public health and humanitarian programming. Objective: We describe a methodology to estimate HIV prevalence among Venezuelan migrants in Colombia. Methods: Respondent-driven sampling, a nonprobability sampling method, was selected for attributes of reaching highly networked populations without sampling frames and analytic methods that permit estimation of population parameters. Respondent-driven sampling was modified to permit electronic referral of peers via SMS text messaging and WhatsApp. Participants complete sociobehavioral surveys and rapid HIV and syphilis screening tests with confirmatory testing. HIV treatment is not available for migrants who have entered Colombia through irregular pathways; thus, medicolegal services integrated into posttest counseling provide staff lawyers and legal assistance to participants diagnosed with HIV or syphilis for sustained access to treatment through the national health system. Case finding is integrated into respondent-driven sampling to allow partner referral. This study is implemented by a local community-based organization providing HIV support services and related legal services for Venezuelans in Colombia. Results: Data collection was launched in 4 cities in July and August 2021. As of November 2021, 3105 of the target 6100 participants were enrolled, with enrollment expected to end by February/March 2022. Conclusions: Tailored methods that combine community-led efforts with innovations in sampling and linkage to care can aid in advancing health research for migrant and displaced populations. Worldwide trends in displacement and migration underscore the value of improved methods for translation to humanitarian and public health programming. [ABSTRACT FROM AUTHOR]

The perception that immigrants represent a burden to national health systems can hinder the development of policies for their inclusion in health coverage. In order to inform the development of such policies, data on the healthcare needs and healthcare spending for immigrants is required. The objective of this article is to compare the clinical characteristics and healthcare‐related expenditures of Venezuelan immigrants and non‐migrants living with HIV in Colombia. We analysed data from the Colombian High‐cost Diseases Fund from February 1, 2018 to January 31, 2019, identifying the hospital and non‐hospital expenditures per patient for Venezuelan immigrants and non‐migrant patients, in both the state‐subsidised and the contributory coverage schemes. We employed binomial negative regression models to compare expenditures between the two groups. In the contributory scheme, the average annual per‐capita expenditure for immigrants was USD $ 859.07 (SD: ± $793.37) for non‐hospital care. For non‐migrants, the average costs were 1,796.53. In the state‐subsidised scheme expenditures were higher on average, but still lower for immigrants than for non‐migrants. After adjusting by clinical and sociodemographic characteristics, non‐hospital per capita expenditures were lower for immigrants as compared with non‐migrants (25,37% lower in the state‐subsidised scheme, and 33,75% lower in the contributory scheme). Hospital expenditures were also lower, but the small sample size limited analysis. To conclude, Venezuelan immigrants living with HIV do not represent a major economic burden to the health system in Colombia. Further studies are required in order to understand if the lower healthcare expenditures of this population are the result of limitations in healthcare access, of clinical characteristics that were not assessed in this study, or of other unmeasured aspects.
