Incidence of type 2 diabetes in Mexico: results of the Mexico City Diabetes Study after 18 years of follow-up

Salud Publica Mex. Jan-Feb 2014;56(1):11-7. doi: 10.21149/spm.v56i1.7318.

Abstract

Objective: To estimate the incidence of type 2 diabetes (T2D) in Mexican population.

Materials and methods: Population based prospective study. At baseline (1990), the population at risk (1939 non-diabetic adults 35-64 years) was evaluated with oral glucose tolerance test. Subsequent similar evaluations were done (1994, 1998, 2008). American Diabetes Association diagnostic criteria were applied.

Results: The period of observation was 27842 person-years, the cumulative incidence of T2D was 14.4 and 13.7 per 1000 person-years for men and women, respectively. Incidence was 15.8, 15.7 and 12.7 per 1 000 person-years for the second (1994), third (1998) and fourth (2008) follow-up phases, respectively. The mean age at diagnosis was 44 years for prevalent cases and 56 years for incident cases.

Conclusions: This is the first estimate of long-term incidence of T2D in Mexican population. The incidence is among the highest reported worldwide. It remained with few changes throughout the study period.
