Effect of a Nutritional Intervention in Athlete's Body Composition, Eating Behaviour and Nutritional Knowledge: A Comparison between Adults and Adolescents.

The objective of the present study is to evaluate and compare the effect of a nutritional intervention between adolescent and adult. In a before and after quasi-experimental clinical study, 32 athletes (21 adults, age range 20–32 years; 11 adolescents, age range: 12–19 years) participated in a nutritional counselling consisting of four consultations separated by an interval of 45 to 60 days. The athlete’s eating behaviour, body composition and nutrition knowledge were evaluated at the beginning and at the end of the protocol. Both groups increased lean body mass and nutritional knowledge. Adolescents increased their mid-arm muscle circumference and improved meal frequency, and daily water intake. Athletes of both groups improved their ingestion of vegetables and fruits and decreased the ingestion of sweets and oils. Adolescents showed a higher prevalence of individuals that remained within or approached to the recommendations of sweets. This is the first study to evaluate and compare the effect of a nutritional intervention between adolescent and adult athletes body composition, eating behaviour and nutritional knowledge. The nutritional counselling has been effective in promoting beneficial changes on the athlete’s eating behaviour, nutritional knowledge and body composition, however, some healthy changes were only experienced by adolescents, especially in the frequency of meals and the intake of sweets.

The relative validity of a food record using the smartphone application MyFitnessPal: Relative validity of a smartphone dietary record

AIM The present study aimed to validate food records on the application MyFitnessPal (MFP), comparing them with paper-based food records (P-FR). METHODS Thirty university students, including males and females, volunteered and recorded dietary intakes on P-FR and MFP food records (MFP-FR). The values of energy, macronutrients and fibre from MFP-FR were compared with data from P-FR, calculated using Brazilian food composition tables. Adjustments for in-person variability and energy intake were performed, and comparisons were made between each data set, using the Wilcoxon signed-rank test, Spearmans correlation and Bland-Altman agreement plots. RESULTS Positive moderate correlations between P-FR and MFP-FR for all variables, and non-significant associations for energy and fibre were found. The Bland-Altman plots showed tendency to underestimation and relatively narrow limits of agreement. Carbohydrate and lipids show trends of increasing the degree of overestimation with increased intake, even after data normalisation. CONCLUSIONS MFP tends to underestimate ingestion of nutrients probably due to inadequacies in the MFP database. However, MFP showed good relative validity, especially for energy and fibre. Its use, as well as other similar applications, should be encouraged, due to ease of assessing dietary information, although careful usage is recommended because of database gaps.

PERFIL DE UTILIZACIÓN DE MEDICAMENTOS ADMINISTRADOS POR SONDA ENTERAL EN EL HOSPITAL UNIVERSITARIO

The objective of this study was to evaluate the conditions of use of medicines in patients receiving enteral nutrition at units of University Hospital. The data collection was done using a structured questionnaire, based on patient’s clinical files and observation of the nurse aides’ routine in the period between January and April of 2009. Results demonstrated that 16.7% of the patients needed a feeding tube replacement because of obstructions. Approximately 52% of prescribed medicines were in solid form and at least eight medicines administered via feeding tube were recognized to be capable of drug-nutrient interaction in enteral feeding and affected at least one patient each. A conclusion can be drawn that there were prescription errors and inadequacy in techniques of administration of

Fatores associados ao risco de insegurança alimentar e nutricional em famílias de assentamentos rurais

Resumo A inseguranca alimentar ocorre quando o direito a uma alimentacao em qualidade e quantidade adequada de forma regular e desrespeitado. O objetivo deste estudo foi identificar a situacao de inseguranca alimentar (IAN) e suas possiveis associacoes com variaveis socioeconomicas e dieteticas em assentamentos rurais de Sergipe. Essa situacao foi verificada atraves da escala brasileira de inseguranca alimentar e as associacoes atraves da analise de regressao multivariada por odds ratio (OR). Foram avaliadas 179 familias de quatro assentamentos do estado de Sergipe. Identificou-se prevalencia de 88,8% de IAN, sendo 48,6% inseguranca leve, 25,1% moderada e 15,1% grave. Associacao estatistica ajustada foi encontrada entre a IAN e as variaveis renda familiar per capita (ORa = 3,11, p = 0,008) e variedade alimentar (Ora = 2,73, p = 0,004). As familias apresentaram alta prevalencia de inseguranca alimentar e nutricional, determinada nesta populacao, pela baixa renda familiar e pela baixa variedade da alimentacao. E imprescindivel politicas publicas mais efetivas, que, de fato, garantam a seguranca alimentar e sejam mais completas, visando tambem a educacao nutricional e maior possibilidade para producao de alimentos.

Inadequações Dietéticas em atletas: Uma Comparação entre homens e mulheres

The present study aimed to evaluate and compare the dietary intake between male and female athletes. The study included 80 high performance athletes, including 43 male and 37 female. The athletes dietary intake was evaluated by a 24-hour recall. Both groups showed a low caloric intake. Men were more inadequate in protein and saturated fat intake. Both groups showed a high inadequacy in vitamin A, E, D and calcium intake. Women had a higher inadequacy in vitamin B12, B3, magnesium, folate, phosphorus, and five times more probability of inadequate iron intake. Women had a more inadequate intake of fruit, meat. Athletes of both sexes present inadequacies on dietary intake, however, these were higher among women.

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.
