Avaliação do consumo de energia e nutrientes de idosas com e sem dor nos joelhos residentes na comunidade

Abstract

Introduction: Although the literature states that there is a relationship between overweight and knee osteoarthritis, the relationship between disease and food consumption is still unclear. Objective: To evaluate the habitual intake of energy and nutrients of community aged women with and without pain in the knees. Methodology: This is a cross-sectional study with symptomatic elderly women (n = 49) and asymptomatic women (n = 51) for knee pain. Food intake was determined by the 2-day mean of the 24-hour Reminder. The diets were analyzed in Dietbox®. The individual energy requirement was estimated using formulas and total calorie consumption was analyzed considering the range of 97 to 103% of energy expenditure. Macronutrient suitability was checked according to the Acceptable Macronutrient Distribution Ranges. The mean intake of fatty acids, cholesterol and fiber was analyzed according to the values proposed by the IV Brazilian Directive on Dyslipidemias. The micronutrient inadequacy was estimated by the Estimated Average Requirement method as the cutoff point and the water consumption was evaluated based on the recommendation of the Food Guide for the Brazilian Population. Statistical Package for the Social Sciences (SPSS) software version 20.0 was used to analyze the data. Results: The mean age was 67 (± 8.0) years for the asymptomatic group and 67 (± 9.0) years for the symptomatic group. As for the energy consumption, macronutrients, fatty acids, cholesterol, fiber and water, there were differences between the groups, which were not statistically significant. The energy intake was inadequate in 96.1% of the asymptomatic ones and in 93.9% of the symptomatic ones. There were also no statistically significant differences among the elderly women regarding the dietary intake of micronutrients, except for the usual consumption of zinc mineral (p value = 0.033), the symptomatic group had an average zinc intake lower than the asymptomatic group. In the groups, the greatest inadequacies (> 50%) were for vitamins A, D, E and folic acid and magnesium and calcium. The lowest inadequacies were for vitamin C and pyridoxine (values between 21.6% and 22.4%). Inadequate intake of vitamin D (100% of the evaluated ones) is highlighted. Conclusion: Among the groups, high prevalence of inadequacy for caloric intake, saturated fatty acid consumption, cholesterol, fiber, water intake, macros and micronutrients were observed. However, no statistically significant differences were observed in food intake of the nutrients, except for the zinc mineral, since the symptomatic elderly had an average zinc consumption lower than the asymptomatic group.
