Abstract
BackgroundColombia has the fourth highest incidence rate of HIV/AIDS among all Latin American countries and it has been increasing since the 1980s. However, the number of studies that addresses this trend is limited. Here, we employed spatial and temporal trend analyses to study the behaviour of the epidemic in the Colombian territory.MethodsOur sample included 72,994 cases of HIV/AIDS and 21,898 AIDS-related deaths reported to the National Ministry of Health between 2008 and 2016. We employed the joinpoint regression model to analyse the annual HIV/AIDS incidence and AIDS mortality rates. In the spatial analysis, we used univariate autocorrelation techniques and the Kernel density estimator.ResultsWhile the HIV/AIDS incidence had an increasing trend in Colombia, the AIDS mortality rate was stable. HIV/AIDS incidence and AIDS mortality showed a downward trend in the 0–14 age group. An upward trend was observed for HIV/AIDS incidence in people older than 15 years and with the highest trend in the 65 years and above group. AIDS mortality showed an increasing trend among people aged 65 years or older. The comparison between the sexes showed an upward trend of HIV/AIDS incidence in all age groups and AIDS-mortality rates in 65 years and above in men, while in women, the incidence was upward among those aged 45 years and above, and concerning the AIDS-mortality rate in the 45–64 group. The high–high clusters of HIV/AIDS incidence and AIDS mortality were located in the Andean and Caribbean regions.ConclusionOur study found an upward trend in HIV/AIDS incidence and a stable trend in the AIDS mortality rate in Colombia. The downward trend in HIV/AIDS incidence and AIDS mortality rate in the 0–14 age group reflects the downwards mother-to-child HIV transmission. The upward trend in HIV/AIDS incidence in older women and AIDS mortality in younger women rates, compared with men, may be due to late diagnosis and treatment. The Caribbean and the ‘coffee belt’ regions were the most impacted by the HIV epidemic, most likely due to sexual tourism. Our results provide crucial information that may help Colombian health authorities fight HIV transmission.
Highlights
Colombia has the fourth highest incidence rate of Human Immunodeficiency Virus (HIV)/Acquired Immunodeficiency Syndrome (AIDS) among all Latin American countries and it has been increasing since the 1980s
The scarcity of public policies for combatting HIV and economic regional disparities are directly correlated with the increase in the incidence of HIV in Latin America (LA), where 1.9 million people live with HIV and AIDS (PLWHA)
HIV/ AIDS incidence showed an upward trend in the period of the study, the AIDS mortality rate was stable
Summary
Colombia has the fourth highest incidence rate of HIV/AIDS among all Latin American countries and it has been increasing since the 1980s. Colombia is part of the Caribbean region, which has the second-highest prevalence of HIV/AIDS in the world after sub-Saharan Africa. In this region, by the end of 2019, there were 330,000 PLWHA, 6900 AIDS-related deaths and 13,000 new HIV infections recorded in the same year. Approximately 50% of Colombian people living with HIV still have not been diagnosed for the virus, and only 55% of PLWHA are on ART. Of those receiving treatment, only 68% are virally suppressed. All Colombians and legal immigrants have access to HIV tests and ART [5]
