[Food consumption, habits, and nutritional status of the population of Reus (VIII). Evolution of energy and nutrient intake from 1983 to 1993].
BACKGROUND
Nutritional characteristics of the mediterranean diet, with a high intake of complex carbohydrates, fibre, monounsatured fatty acids and vegetables, are related to a lower prevalence of some nutritional associated diseases. The aim of our study was to perform a longitudinal analysis of the evolution of food intake in a mediterranean population in order to observe its influence on the energy and nutritional intake and their balance. The latter could have some effects on health status.


METHODS
Dietary intake was evaluated using the 24 hours recall method in a representative sample (n = 941, age range = 10-69) of a Reus population. This longitudinal study consisted of 70% of the samples studied in 1983 using identical methodology.


RESULTS
During this decade (1983-1993), energy intake decreased significantly 180 kcal/day for men and 158 kcal/day for women, carbohydrates being the main cause for this drop (132 and 84 kcal/day less for men and women, respectively). Protein intake decreased significantly in both sexes, 5.6% for men and 8.0% for women. However, the evolution of fat intake was different for men (no changes) and for women (a significant decrease of 5.7%). Saturated and monounsatured fatty acids did not show significant changes in this decade. Cholesterol intake decreased significantly in both sexes. Energy percents obtained from lipids, saturated and monounsaturated fatty acids significantly increased. However, in absolute values very little changes in fat intake in both sexes were observed.


CONCLUSIONS
The dietary pattern evolved to a lower energy intake with an increment of the percentage of dietary lipids, but this feature was did not reflect a greater fat intake in absolute values. Moreover, the main characteristics of the typical mediterranean diet (which is basically different to the usual diet of other non mediterranean european countries mainly due to its richness in monounsaturated fatty acids) did not change in the period analyzed.
