Intervenção nutricional educativa como ferramenta eficaz para mudança de hábitos alimentares e peso corporal entre praticantes de atividade física

The scope of this study was to evaluate the effectiveness of two methods of educational nutritional intervention together with women who practice regular physical activities by fostering the adoption of healthy eating habits. The study population consisted of 52 women aged between 19 and 59 who frequented the Academia da Cidade Program in Aracaju in the State of Sergipe. The study was a randomized comparison of two intervention groups and was of the pre-test/post-test variety. The educational activities were based on two protocols - one less intensive (P1 Group) and one more intensive (P2 Group) - over a period of two months. The variables analyzed were nutritional knowledge, anthropometric measurements and changes in eating habits. The changes identified were improvement in eating habits and reduction in weight and Body Mass Index for the P2 group. The modifications identified referred mainly to increased consumption of fruit and vegetables, reduction of fat in cooking, reduction in the volume of food eaten per meal and increased meal frequency. In relation to nutritional knowledge, only 2 of the 12 questions showed significant changes. The most intensive method proved effective in changing dietary habits leading to weight loss.

Índice de qualidade da dieta de mulheres usuárias de um programa de atividade física regular "Academia da Cidade", Aracajú, SE

Foram coletados dados sociodemograficos, antropometricos e dieteticos de 169 mulheres. O Indice de Qualidadeda Dieta foi obtido a partir da media de aplicacao de dois recordatorios de 24 horas. Os dados do Indice deQualidade da Dieta total e de seus componentes foram analisados de acordo com o indice de massa corporal(obesos e nao obesos) e a faixa etaria (adultos jovens e adultos velhos).

Plasma Total Antioxidant Capacity and Cardiometabolic Risk in Non-Obese and Clinically Healthy Young Adults

Background The oxidative biomarkers play an important role in the genesis of cardiometabolic risk-related processes. Objective To investigate the total antioxidant capacity of plasma and its association with cardiometabolic risk in non-obese and clinically healthy young adults. Methods University students of the state of Sergipe, Brazil, aged between 18 and 25 years, were recruited for this study from May of 2013 and October of 2014. Anthropometric, clinical and biochemical parameters were measured and analyzed using protocols which were previously standardized and described in the literature. The measurement of plasma total antioxidant capacity was based on the ability that all the antioxidants present in the sample (plasma) have to inhibit the oxidation of the oxidizable substrate ABTS (2,2`- Azino-di-[3-ethylbenzthiazoline sulphonate]) to ABTS•+ by metmyoglobin. Results Approximately 25% of the sample presented more than one component of cardiometabolic risk. Low HDL-cholesterol was the most prevalent component. Compared to absence of components, the subjects with at least one component presented greater body weight and waist circumference, higher levels of diastolic blood pressure and fasting glucose, greater total cholesterol/HDL-c ratio, and lower levels of HDL-c (p < 0.05). Fasting glycemia was the only parameter which was associated with total antioxidant capacity (R2 = 0.10; β = 0.17; p = 0.001). Conclusions The plasma total antioxidant capacity was not able to predict the cardiometabolic risk components due possibly to the establishment of compensatory mechanisms that become activated in physiological conditions.

DIET COMPOSITION IS ASSOCIATED WITH OBESITY IN ACTIVE WOMEN

El objetivo de este estudio fue avaluar la contribucion de la composicion de la dieta en el sobrepeso de mujeres que practican actividad fisica, basado en el supuesto de que el alto consumo de energia y lipidos y el bajo consumo de carbohidratos y fibras son factores preponderantes en la etiologia de la obesidad de esta poblacion. Se utilizo un analisis transversal en 165 mujeres adultas que practicaban, por lo menos, 150 minutos de actividad fisica moderada por semana. Las variables de resultado fueron el indice de masa corporal (IMC) y la circunferencia de la cintura (CC). Las personas se clasificaron en grupos segun el IMC - obesos (IMC ≥ 30 kg/m2) y no obesos (IMC < 30 kg/m2) - y de acuerdo con CC - con riesgo ≥ 88 cm y sin riesgo <88 cm. La ingestion dietetica se evaluo con una encuesta de recordatorio de 24 horas. Para hacer la comparacion de las medias de consumo de los grupos se utilizo el analisis de varianza (ANOVA). Se observo que 69,1% de las mujeres presentaban sobrepeso/obesidad. Las mujeres obesas consumian significativamente mas energia y colesterol y menos carbohidratos (p <0,05) y menos consumo de fibras (p <0,10), lo que no sucede en las mujeres no obesas. Ademas, las mujeres con mayor CC consumian significativamente mas energia (p <0,05) y presentaron una tendencia para menor consumo de carbohidratos y fibras (p <0,10), lo que no sucede en las mujeres con menor CC. Los resultados mostraron que, aunque estas mujeres eran fisicamente activas, tenian un IMC medio de sobrepeso, lo que indica que los habitos alimentarios estan altamente correlacionadas con este factor. Se sugiere que el bajo consumo de carbohidratos y fibras y el alto consumo de energia y colesterol han contribuido expresivamente para la obesidad entre las mujeres.
