Hábitos alimentarios de la población de Valparaíso: encuesta de base CARMEN conjunto de acciones para la reducción multifactorial de las enfermedades no transmisibles / Eating habits of the population from Valparaíso: CARMEN base survey actions for the multifactorial reduction of noncommunicable chronic diseases

Las enfermedades crónicas no transmisibles (ECNT) han tenido un aumento progresivo durante en las últimas décadas en nuestro país, ocupando los primeros lugares como causas de morbilidad y mortalidad de los adultos. Estas causas se pueden modificar si intervenimos sobre los factores de riesgo que predicen o anticipan el daño. Dentro de los factores de riesgo de la población, la alimentación tiene una preponderancia como un vehículo de prevención. Sin embargo, no existen cifras claras del consumo de alimentos a escala nacional, contando sólo con algunos datos parciales derivados de trabajos de investigación. El proyecto CARMEN (conjunto de acciones para la reducción multifactorial de las enfermedades no transmisibles), tuvo por objeto medir los factores de riesgo y hábitos conductuales de una población representativa de la comuna de Valparaíso. El estudio se efectúo a una muestra de 3120 sujetos (1020 hombres y 2100 mujeres) entre 25 y 64 años. Más del 94 por ciento de la población consumía aceite como su principal fuente de grasa, un 71,7 por ciento de los hombres y un 63,7 por ciento de las mujeres indica no consumir leche y un 98 por ciento de los encuestados consume pan diariamente. Se discute la relación de los hábitos alimentarios con las ECNT

Material and methods: a random samples of people aged 25 to 64 years old living in Valparaiso, Chile was studied. Subjects were questioned about smoking and physical activity habits. Blood pressure, height and weight were measured using standardized techniques at their homes and blood samples were obtained to measure serum lipid levels and oral glucose tolerance test at the nearest outpatient clinic.

Prevalencia de hipertensión arterial en Valparaíso: resultados de la encuesta de base el programa CARMEN: conjunto de acciones para la reducción multifactorial de las enfermedades no transmisibles / Prevalence of hypertension in Valparaíso: results of the base survey of CARMEN program

Background: There is little information about the real prevalence of hypertension in Chile. Aim: To assess the adjusted prevalence of hypertension and its main therapeutic measures among adults living in Valparaiso, Chile. Material and methods: A random sample of dwellings in Valparaiso was chosen. Among these, an individual of 25 to 64 years old was randomly surveyed for risk factors for chronic diseases and sociodemographic parameters. Blood pressure, weight, height, oral glucose tolerance test, fasting cholesterol and triglycerides were also measured. Prevalence was pondered according to age, sex, and probability of selection in the dwelling interior. Results: Three thousand one hundred twelve individuals were studied. The adjusted prevalence of hypertension was 11.4 percent (11.6 percent among females and 10.6 percent among men). The prevalence increased along with age from 3 and 1.9 percent in men and women of 25 to 34 years old respectively, to 18.2 and 27.4 percent among men and women of 55 to 64 years old (p< 0.01). People of low socioeconomic level had a higher prevalence of hypertension than those of high socioeconomic level (14.2 and 9.3 percent respectively, p < 0.05). Diabetes, obesity and hypercholesterolemia were significantly more frequent in subjects with hypertension than in the general population. Forty four percent of diagnosed hypertensives were receiving medications (angiotensin converting enzyme inhibitors 40 percent, calcium antagonists 34 percent, beta blockers 22 percent). Twenty five percent of patients were treated with a combination of medications. Of those treated, only 22 percent had normal blood pressure levels at the moment of examination. Conclusions: High blood pressure is an important public health problem that requires more efficient detection and treatment programs
