SERRA MAJEM, Lluís et al. Trends in the nutritional status of the Spanish population: Results from the Catalan nutrition monitoring system (1992-2003). Rev. Esp. Salud Publica [online]. 2007, vol.81, n.5, pp.559-570. ISSN 2173-9110.

Background: The purpose of this study was to evaluate the changes in the nutricional habits and nutricional status of the Catalan population over 10 years interval of the two Catalan Nutricional Surveys conducted in 1992-93 and 2002-03. Methodos: 2641 individuals in 1992-93 and 2060 individuals in 2002-03 aged 10 to 75 years participated in the surveys. Two 24 hour recall, a food frequency questionnaire, and a general questionnaire with information on physical activity, knowledge and opinions on nutrition and supplements use were administered. Weight (Kg), height (cm) and waist circumference (WC) (cm) were measured. A subsample of the population underwent a biochemical evaluation. Total cholesterol, HDL cholesterol, LDL cholesterol, tryglicerides and ß-carotene, a-tocopherol and retinol were measured. Results: A decrease in the consumption of fruit, vegetables, potatoes, meat and fish and an increase in the consumption of dairy products and fast food (in young individuals) were reported. An increase in the mean value of Body Mass Index (BMI) was observed among males, and an increase in WC mean value was observed in males and females. BMI value decreased in females (except among the younger ones). The prevalence of obesity increased among males (from 9.9% to 16.6%), but not in females. Both total cholesterol and HDL cholesterol decreased. A decrease was observed in the percentage of population with sedentary habits during leisure time. Conclusions: There is a need for an effective nutrition policy promoting healthy nutrition in accordance with the ongoing dietary guidelines.
