[Prevalence and interrelations of noncommunicable chronic diseases and cardiovascular risk factors in Mexico. Final outcomes from the National Health Survey 2000].

Purpose: To determine the prevalence and interrelation of noncommunicable chronic diseases (NCCD), obesity, smoking, and proteinuria in the adult population (between 20 and 69 years of age) of Mexico, and their stratification according to age, gender, and geographical area.
Method: During the year 2000, a probabilistic national survey was performed in 45,300 persons. The sample size was calculated to approach NCCD with a minimal estimated prevalence of 6%. The survey corresponds to type III of the step-by-step method described by WHO. Data were weighted for the distribution of the population and gender, according to the national survey of population and housing (National Institute of Statistics and Geography, INEGI).
Results: A total of 38,377 (98.8%) of individuals were included in the analysis; 69.4% were women. Average age for men was 39.4 +/- 12.9 and for women 38.6 +/- 13.0. National average prevalence for hypertension was 30.05%, for diabetes of 10.7%, for obesity of 24.4%, for abnormal capillary glucose of 12.7%, and for proteinuria of 9.2%. Prevalence for hypertension and diabetes were directly related with age, body mass index, and waist perimeter. The pyramidal distribution of the Mexican population determined that the greatest proportion of prevalence of NCCD was given by those under 54 years of age with a statistical significance (> 75%).
Conclusion: ENSA 2000 demonstrates the marked increase in NCCD prevalence in the Mexican population and alerts on the urgent need of national strategies to restrain this important public health problem. Strategies must be oriented towards an integrated approach of the NCCD, since their clinical and physiopathological interrelation is clearly demonstrated through ENSA 2000.
