Abstract

Introduction: Diagnosing and treating human immunodeficiency virus carriers has led to the identification of a higher prevalence of said infection and, therefore, of a higher risk of transmission of the virus.

Objective: To find out the trend of new cases of human immunodeficiency virus infection carriers at the Instituto Mexicano del Seguro Social (IMSS) in Mexico within the 2003-2017 period.

Methods: Patients affiliated to the IMSS were analyzed. Data from 42,181 newly-diagnosed cases were collected, with variations related to gender and age being observed. Age-standardized rates per 100,000 population were obtained.

Results: The highest mean annual percentage change in males was documented in adolescents (13.0, 95% CI = 9.9, 16.1). Heterogeneous trends were recorded for women, with a significant overall decrease (-2.2, 95% CI = -3.4, -1.0), but growing trends were also observed in some groups.

Conclusions: Our results suggest that the human immunodeficiency epidemic in patients cared for at the Instituto Mexicano del Seguro Social is concentrated in males, with a growing trend particularly in adolescents.

Introducción: Hacer el diagnóstico y tratar a portadores del virus de la inmunodeficiencia humana ha llevado a identificar mayor prevalencia de esa infección y, por lo tanto, de un mayor riesgo de transmisión de este virus.

Objetivo: Conocer la tendencia en México de los nuevos casos de portadores de infección por el virus de la inmunodeficiencia humana en el Instituto Mexicano del Seguro Social (IMSS) en el periodo 2003-2017.

Métodos: Se analizaron pacientes asegurados en el IMSS. Se obtuvieron datos de 42 181 casos recién diagnosticados y se analizaron las variaciones relacionadas con el sexo y la edad. Se obtuvieron las tasas estandarizadas por edad por 100 000 personas.

Resultados: El cambio porcentual anual promedio más alto en hombres se documentó en adolescentes varones (13.0, IC 95 % = 9.9, 16.1). Se registraron tendencias heterogéneas en las mujeres, con una disminución total significativa (–2.2, IC 95 % = –3.4, –1.0), pero también se observaron tendencias crecientes en algunos grupos.

Conclusiones: Los resultados sugieren que en el IMSS, la epidemia de la inmunodeficiencia humana adquirida se concentra en hombres, con tendencia creciente particularmente en adolescentes.
