[Impact of a nutrition education program on the lipid profile and food habits of a working adult population]. / Impacto de un programa educativo nutricional sobre el perfil lipídico y los hábitos alimentarios de una población adulta laboralmente activa.

To evaluate the influence of health care education of the diet, we studied, in a sample of 68 workers (47 men and 21 women), the usual food intake (by means of a weekly registration technique), the anthropometry and the lipid profile, before and after giving a nutritional information program which lasted one year. At the end thereof, we observed a significant reduction in the global caloric intake, at the expense of a lower supply of proteins and fats (mainly saturated fats), which translated into a percentile distribution of macronutrients, which more closely resembles the dietary recommendations. The average anthropometric parameters did not vary. With respect to the lipid profile, a decrease of the plasma levels of LDL and HDL cholesterol was observed. These results confirm the capacity of educational interventions in changing the eating habits to a more healthy style, with repercussions on the lipid profile.
