Background: The identification of an association between alimentary and nutritional factors and different diseases has led to the study of alimentary habits in different populations. The consumption of energy and macronutrients was analyzed in two urban populations in the province of Barcelona (Spain).
Methods: One thousand thirty-four randomly selected individuals from primary care centers (PCC) were studied by a systematic sampling of all the out patient consultations over one year and to those to whom a semiquantitative questionnaire of frequency foodstuffs was given to estimate their normal diet. The subjects included all those residents in the two towns studied from 13 to 80 years of age who attended the PCC during the study period.
Results: The percentage of subjects from Vilanova i la Geltrú who were found to be high consumers of milk and derivatives, fish and vegetables was significantly higher in comparison with subjects from Gavá. The males of both towns presented a higher mean consumption of carbohydrates and energy than the females. On comparison of the consumption between the 2 populations, the mean carbohydrate diet ingested was significantly greater in the population from Gavá in both sexes as was the consumption of energy and total lipids between women and men, respectively.
Conclusions: The population studied presented a clear pattern of Mediterranean diet consumption with elevated ingestion of carbohydrates and monounsaturated fats.
