Abstract

In the literature there are few materials available associating knowledge in nutrition with nutritional status, and that there are, in most cases, duly validated methodologies are not used. The first work in which a validated methodology was used, was carried out in order to associate the nutritional knowledge with the Body Mass Index (BMI), and this found no correlation between the two. Given the above, it is important to expand the information on the relationship between nutritional knowledge and nutritional status of physically active women, in order to identify the level of knowledge in nutrition can be configured as one of the determinants of nutritional status. Therefore, the aim of this study was to evaluate the nutritional knowledge of physically active women and relate it to the nutritional status of them. It conducted a cross-sectional study through questionnaires that characterized the sample evaluated knowledge in Nutrition nutritional status of physically active women denizens of a health Fortaleza. The study population consisted of women aged between 15 and 54 years. To characterize one demographic questionnaire sample was applied subsequently received a questionnaire that assessed the nutritional knowledge. Anthropometric measures adopted in this study are height, weight, calculate body mass index (BMI), arm circumference (AC), waist circumference (WC), neck circumference (NC), and skinfold method for determining the body composition. For data analysis we used the statistical software package for social sciences (SPSS) version 15.0. The descriptive analysis for categorical variables was performed using frequency distribution, absolute and percentage and numerical variables will be used the mean and standard deviation. The study sample consisted of 30 women physically active with mean and standard deviation of 30 ± 11.5 years old. As for education, 23.3% completed primary education, 46.7% High school and 30% higher education. Analyzing the use of supplements, most of the population (76.7%) reported not make use of these and 23.3% said consumption. Regarding nutritional status, the study population had a mean weight of 62.2 ± 9.94 kg, mean height of 1.58 ± 0.06 m and average body mass index (BMI) 24.6 ± 3, 17 kg / m2. The second BMI, the population was classified as overweight / obesity (53.3%), with 46.7% the percentage of women classified as eutrophic. With respect to the suitability of the circumference arm percentage (AC%) calculated, it was found that 16.7% of women were in a state of malnutrition, 63.3% eutrophic and 20% overweight / obesity. According to the neck circumference measurements (NC), we can see that 90% of the sample was classified as overweight / obesity and 10% with normal weight. Regarding the measure waist circumference (WC), 46.7% and 23.3% were classified with risk and high risk, respectively, of developing cardiometabolic complications and 30% did not have any chances. The average percentage of body fat indicated that 50% of women had excess body fat. Regarding the nutritional knowledge, it was found that the average total of quiz correct answers was 47.4%, featuring low knowledge. Through the percentage results of knowledge in nutrition assessment found no significant relationship (p> 0.05) with schooling and nutritional status classifications obtained through the circumference of the neck, waist circumference, adequacy percentage of arm circumference , BMI and body fat percentage
