Physical activity and survival in chronic comorbidity among adult HIV patients in Ethiopia: a prospective cohort study

Background Antiretroviral therapy enables people living with HIV to live long lives, and these advances have transformed HIV infection from an acute to a chronic disease.

Many non-communicable diseases, including type 2 diabetes, heart disease, and stroke, are influenced by physical inactivity.

Therefore, the aim of this study was to assess the level of physical activity and survival in chronic co-morbidity among adult people living with HIV in Ethiopia.

Methods An institution-based prospective cohort study of adult people living with HIV was conducted between 2019 and 2021.

We included 422 people living with HIV at baseline.

After the baseline visit, 364 patients without hypertension or diabetes, were followed up for two years.

Nine trained nurses used a pre-tested, structured questionnaire to collect data during routine care consultations in three hospitals in southern Ethiopia.

STATA version 15 was used to analyze the data.

To estimate the survival probability of developing chronic comorbidities, a Kaplan-Meier survival curve was used.

A Cox proportional hazards model was fitted to identify the predictors of the development of chronic comorbidities.

Result In the current study, 39% of the participants were found to have a low level of physical activity.

Those who had self-management skills to maintain physical activity ( p  = 0.023), considered physical activity an important aspect of their HIV management ( p  = 0.003), and regularly attended social support groups ( p  = 0.002) had significantly higher levels of physical activity.

The risk of chronic comorbidity increased over time, with a rate of 10.83 chronic comorbidities per 1000 persons per month.

Lack of regular exercise [AHR: 2.04; 95% CI: (1.03, 5.13)], low physical activity [AHR: 2.01; 95% CI: (1.03, 7.89)], BMI greater than 25 kg/m^2 [AHR: 2.74; 95% CI: (1.31, 5.12)] and low fruit and vegetable intake [AHR = 2.57; 95% CI: (1.28, 6.49)] were all associated with the development of chronic comorbidity.

Conclusion The prevalence of physical inactivity is high in the study population.

A physical activity program for people living with HIV should be considered, and the promotion of self-management skills should be integrated into HIV care programs.
