RESUMO

In Mexico, the incidence and prevalence of coronary heart disease has increased over the past three decades and has become the leading cause of death in some areas of the country. Hypercholesterolemia (HC) is a major risk factor for coronary atherosclerosis and most developed countries currently have public health strategies that attempt to reduce the level of cholesterol. In order to learn the mean total cholesterol values and the prevalence of HC, an epidemiologic survey was carried out in a representative population sample that included men and women aged 1 to 98 years, across the nation. In this report, we present the findings in children and teenagers of both sexes (n = 34369). Considering the country as a whole, the mean serum TC was 147 +/- 35 mg/dl, the prevalence of borderline hypercholesterolemia (TC between 170 and 199 mg/dl) was 14.7% and the prevalence of high risk hypercholesterolemia (TC > or = 200 mg/dl) was 6.7%. This cross sectional study demonstrated the existence of significant geographic differences in serum TC, with mean state values ranging from 133 mg/dl in the south to 164 mg/dl in the north. The prevalences of high risk hypercholesterolemia was as high as 18.2% in Baja California Norte and as low as 2.5% in the state of Morelos. These geographic differences in total cholesterol and prevalence of hypercholesterolemia were already present at one year of age and persisted throughout childhood and adolescence.

RESUMO

A National Serum Bank was established to store sera obtained during the National Seroepidemiological Survey performed in Mexico in 1987. More than 70,000 serum samples were obtained from subjects of either sex 1-99 years of age in each of the 32 states of the country. The current collection of sera includes 28,704 male samples and 40,629 female samples. This paper describes the procedures for handling serum samples, including reception registry, storage and distribution to several laboratories for detection of measles, rubella, poliomyelitis, AIDS, diphtheria, pertussis, tetanus, brucella, salmonella, amoeba, toxoplasma, American trypanosomiasis and cysticercus. Determinations of total cholesterol were also made in order to describe its distribution and to identify the prevalence of hypercholesterolemia.
