Prevalence and distribution of type 2 diabetes mellitus in Mexican adult population: a probabilistic survey

objective: to describe the prevalence, distribution and degree of control of type 2 diabetes (t2d) in mexican population. material and methods: subjects were classified as previously diagnosed t2d (pd); or as "finding of the survey" (fs) (glucose >126 mg/dl). hemoglobin a1c was measured in pd-subjects. results: the prevalence for pd-t2d was 7.34% (95%ci 6.3, 8.5) and for fs 7.07% (95%ci 6.1, 8.1), summing 14.42%; (7.3 million diabetics). 5.3% of pd-t2d were in good, 38.4% in poor and 56.2% very poor control. older age (or=0.96, 95%ci 0.94, 0.97), lower bmi (or=0.95, 95%ci 0.91, 1.0), were protective for poor control. affiliation to private services (or=1.77, 95%ci 0.98, 3.13), larger t2d duration (or=1.05, 95%ci 1.01, 1.08), and combining oral medication and insulin (or=16.1, 95%ci 1.61, 161) were riskier. conclusions: we found an alarming prevalence of t2d in mexican population; the majority of pd diabetics are in poor control. research on the latter is warranted.
