Prevalence of comorbidity tuberculosis and diabetes mellitus in Paraguay, 2016 and 2017

Céspedes et al.

Objective.

To estimate the national and regional prevalence of tuberculosis (TB) and diabetes mellitus (DM) co-morbidity and identify the factors associated with this co-morbidity in Paraguay.

Methods.

Cross-sectional study in patients with TB notified in 2016 and 2017 and registered in the database of the National TB Control Program. The prevalence of self-reported DM was estimated in patients with TB. A multivariate binomial regression model was used to know the factors associated with TB-DM co-morbidity to
adjust the prevalence ratios (PR) according to standard errors by health region.

Results.

Between 2016 and 2017, 5 315 cases of TB were reported. The prevalence of TB-DM co-morbidity was 6.3% in 2016, 6.0% in 2017, and 6.2% in both years. It was highest in Itapua (9.2%), Alto Paraguay (8.0%), Alto Parana (7.5%), Central (7.4%) and Asuncion (7.2%). The median age of people with DM was higher than
that of those without DM (55 vs 33 years; P < 0.001). Being older than 45 years (RP = 18.3), history of hypertension (RP = 2.17), diagnostic baciloscopy +++ (RP 1.98), and history of chronic obstructive pulmonary disease (COPD) (RP 1.68) were associated with greater co-morbidity. A lower co-morbidity was associated with belonging to the indigenous population (RP = 0.26), human immunodeficiency virus infection (RP = 0.44), history of drug dependence (RP = 0.49), male sex (RP = 0.64), and extrapulmonary TB (RP = 0.75).

Conclusions.

The prevalence of self-reported co-morbidity of TB-DM in Paraguay was 6.2% in 2016-2017 and varied between health regions. Age, sex, high bacillary burden at diagnosis and co-morbidity with hypertension and COPD were associated with higher co-morbidity. These findings will allow prioritizing population groups to increase screening performance, diagnosis, treatment and prevention of TB-DM co-morbidity in Paraguay.
