We studied the prevalence of non-insulin dependent diabetes (NIDDM) an
d hyperlipemia in older than 15 years old population in the city of Sa
n Luis Potosi and in a rural area 50 km north of this city. They are l
ocated in the state of San Luis Potosi in the central plateau of Mexic
o. A total of 1136 subjects were surveyed (645 males, 491 females). We
ight and height were measured and the body mass index (BMI) calculated
in all subjects. After a fasting capillary sample was obtained, 75 g
of glucose were given and a second sample was taken 120 minutes later.
The WHO recommendations for diagnosis of DM were used. The overall pr
evalence of DM was 10.0%: the lowest rate was for individuals in the r
ural area (0.9%) which contrasts with the 11% seen in the urban popula
tion (p 0.0001). In the urban subjects, the highest rates were observe
d in the very low income group (27.7%) whereas the low income group ha
d a rate of 6.2%; the prevalence was 7.0, 7.7 and 18.2% in the medium,
high medium and high socioeconomic groups. The prevalence was influen
ced by age, BMI, sex (males=6.8% females=14.3%) and socioeconomic stat
us; hypercholesterolemia (>200 mg/dL) was found in 16%. In conclusion,
we have documented high rates of NIDDM in a mexican urban population
with very high levels in the very poor which contrasts with the rural
population.
