Incidence and Mortality Rates and Clinical Characteristics of Type 1 Diabetes among Children and Young Adults in Cochabamba, Bolivia

Abstract EN

Objectives.

To determine incidence, mortality, and clinical status of youth with diabetes at the Centro Vivir con Diabetes, Cochabamba, Bolivia, with support from International Diabetes Federation Life for a Child Program.

Methods.

Incidence/mortality data analysis of all cases (<25 year (y)) diagnosed January 2005–February 2017 and cross-sectional data (December 2015).

Results.

Over 12.2 years, 144 cases with type 1 diabetes (T1D) were diagnosed; 43.1% were male.

Diagnosis age was 0.3–22.2 y; peak was 11-12 y.

11.1% were <5 y; 29.2%, 5–<10 y; 43.1%, 10–<15 y; 13.2%, 15–<20 y; and 3.5%, 20–<25 y.

The youngest is being investigated for monogenic diabetes.

Measured incidence in Cercado Province (Cochabamba Department) was 2.2/100,000 children < 15 y/y, with ≈80% ascertainment, giving total incidence of 2.7/100,000 children < 15 y/y.

Two had died.

Crude mortality rate was 2.3/1000 patient years.

Clinical data on 141 cases <35 y: mean/median HbA1c was 8.5/8.2% (69/62 mmol/mol), levels higher in adolescents.

Three were on renal replacement therapy; four others had substantial renal impairment.

Elevated BMI, triglycerides, and cholesterol were common: 19.1%, 18.3%, and 39.1%, respectively.

Conclusions.

Bolivia has low T1D incidence.

Reasonable glycemic control is being achieved despite limited resources; however, some have serious complications and adverse cardiovascular risk factor profiles.

Further attention is needed for complications.
