Abstract (EN): Objective: To describe the relationship between dietary intake and different levels and types of physical activity (PA). Design: Cross-sectional evaluation of the EPIPorto study. Energy expenditure (metabolic energy equivalent tasks) and dietary intake during the past year were assessed using a PA questionnaire and a semi-quantitative food-frequency questionnaire, respectively. Selling: Representative sample of adults in Porto, Portugal. Subjects: Data were analysed for 2404 Portuguese Caucasian adults, aged between 18 and 92 years. Results: For total PA, males who were active had significantly higher mean intake of energy (10.76 (2570.7) vs. 9.78 (2336.9) MJ/d (kcal/d), P < 0.001) and lower level of protein consumption (16.9 vs. 17.6% of energy, P < 0.001) compared with sedentary males. In males, the assiciation between total PA and energy intake remained after adjustment for age, education and body mass index. Similar results were obtained when occupational activity was analysed. Concerning the energy expended in leisure time, in both genders, after adjustment for the previously described variables, a significant positive association was found between PA and intake of vitamin C (g/d): beta=0.12, 99% confidence interval (CI) 0.02, 0.21 for females and beta=0.13, 99% CI 0.03, 0.22 for males. Leisure-time activity in females was also positively associated with intakes of fibre, vitamin E, folate, calcium and magnesium, and negatively associated with saturated fat. Conclusions: Higher levels of PA in leisure dine were associated with higher intakes of iiiicronutrients and lower intakes of saturated fat, particularly in females. For total and occupational PA, similar nutrient intake was observed between active and sedentary individuals.
