ABSTRACT

Some authors have suggested that body weight dissatisfaction may be high in students majoring in dietetics. Therefore, this study was conducted to examine the extent of body weight and image dissatisfaction in a sample of women in dietetics major. Additionally, predictors of magnitude of body weight dissatisfaction were analyzed. Participants were 62 volunteers with normalweight whose mean age was 21.87±1.89 years old (non-random sample). The assessment instruments included anthropometric measurements, a somatomorphic matrix test and an eating disorders inventory (EDI-2). Data were analyzed using SPSS vs. 15.0. A larger proportion of students chose an ideal body weight lower than actual weight (67.7%) and body image with less body fat and more muscle mass than actual values (56.4%). The magnitude of body weight dissatisfaction was associated with muscle mass and body fat dissatisfaction, and with the subscale of EDI-2 “body dissatisfaction”. So, from a public health standpoint, we consider important to continue working in this line of research with the aim of better understanding the extent of body weight dissatisfaction in women dietitians, and how this dissatisfaction could interfere with their professional practice.


Algunos autores han sugerido que los estudiantes de Dietética pueden presentar una elevada insatisfacción con el peso corporal. Por este motivo, se llevó a cabo el presente trabajo con el objetivo de analizar la insatisfacción con el peso y la imagen corporal en una muestra de mujeres estudiantes de Dietética. Además, se analizaron predictores de la magnitud de la insatisfacción con el peso corporal. Las participantes fueron 62 voluntarias con normopeso que tenían una media de edad de 21,87±1,89 años (muestra no aleatoria). La evaluación incluyó medidas antropométricas, el test somatomórfico matrix y el eating disorders inventory (EDI-2). Los resultados se analizaron con el programa estadístico SPSS vs. 15.0. Un elevado porcentaje de estudiantes eligieron un peso ideal menor que su peso actual (67,7%) e imágenes corporales con menos grasa corporal y más masa muscular que la que tienen actualmente (56,4%). La magnitud de la insatisfacción con el peso corporal se asoció con la insatisfacción con la grasa corporal y la masa muscular, y con la subescala “insatisfacción corporal” del EDI-2. Por lo que, desde el punto de vista de salud pública, consideramos de interés seguir trabajando en esta línea de investigación con el objetivo de comprender mejor el grado de insatisfacción con el peso corporal en mujeres dietistas, y cómo esa insatisfacción podría afectar a su práctica profesional.

ABSTRACT

The aging of a human being is a natural biological process rather thana pathologic one, characterized by a series of morpho-physiologicalbiochemical and psychological changes that take place throughout the liveof human beings. The in? uence of the aging process on the nutritionarequirements is the object of many studies that were carried out in order tdetermine the adequate intake of nutrients to meet the requirements of thhealthy elderly population. Elderly people should intake proteins in suf? cienquantity to reduce the loss of muscle mass related to aging. However, thhigh intake of this nutrient might represent some undesirable effects tthe health of elderly people, due to kidney and liver problems. This papereviews some articles on protein requirements for the elderly and dietarstudies in the elderly population related to protein intake, using the PubMedDatabase, in a search period between 1978 and 2003. The keywords usedwere: amino acids, protein recommendation, metabolism, elderly.


El envejecimiento del ser humano es un proceso biológico natural y no patológico caracterizado por una serie de alteraciones morfofisiológicas, bioquímicas y psíquicas que acontecen en el organismo a lo largo de toda la vida. La influencia del proceso de envejecimiento sobre las necesidades nutricionales es objeto de numerosos estudios conducidos para establecer la ingestión adecuada de nutrientes para una población anciana saludable. La ingestión de proteínas en el adulto mayor debe suplir la pérdida muscular relacionada con la edad, sin embargo su consumo en exceso puede provocar problemas renales y alteraciones hepáticas que son indeseables. Este artículo revisa algunos trabajos sobre las necesidades de proteínas para el adulto mayor utilizando la Base de Dados PubMed, en el período de 1978 a 2003. Las palabras clave utilizadas para La búsqueda fueron: aminoácidos, necesidades proteicas, metabolismo, adulto mayor.


O envelhecimento do ser humano é um processo biológico natural, e não patológico caracterizado por uma série de alterações morfofisiológicas, bioquímicas e psicológicas que ocorrem no organismo ao longo da vida. A influência do processo de envelhecimento sobre as necessidades de nutrientes é objeto de numerosos estudos que têm sido conduzidos para estabelecer a ingestão adequada de nutrientes para suprir as necessidades da população idosa saudável. A ingestão de proteínas do idoso deve ser na quantidade suficiente para diminuir a perda muscular relacionada com a idade, entretanto, o consumo elevado deste nutriente também pode apresentar efeitos indesejáveis à saúde dos idosos, devido a problemas renais e alterações hepáticas. Este artigo revisa alguns trabalhos sobre recomendações de proteínas para idosos e estudos dietéticos, em relação à ingestão de proteínas neste grupo etário, utilizando a Base de Dados PubMed, no período de pesquisa compreendido entre 1978 e 2008. Os unitermos utilizados na pesquisa foram: aminoácidos, recomendações de proteína, metabolismo, idoso.

ABSTRACT

O presente estudo objetivou avaliar a ingestão alimentar quanto à qualidade nutricional de atletas adolescentes do sexo feminino, comparando modalidades esportivas que apresentam características distintas quanto ao gasto energético e ao controle de peso corporal das atletas. Foram estudadas as atletas entre 10 e 14 anos, pertencentes às equipes de natação, vôlei, ginástica olímpica e rítmica do Clube Grêmio Náutico União de Porto Alegre. O cálculo da ingestão de nutrientes foi baseado no registro alimentar de três dias. A ingestão de macro e micronutrientes foi comparada com as recomendações da Organização Mundial de Saúde e com as Dietary References Intake, respectivamente. Foram estudadas 45 atletas (13 nadadoras, 17 jogadoras de vôlei, sete atletas da ginástica olímpica e oito da ginástica rítmica). A natação foi o grupo que apresentou maior média de consumo de energia com diferença de aproximadamente 1000 Kcal/dia das demais modalidades. Com relação ao consumo de carboidrato por quilo de peso corporal, as atletas de natação e GRD apresentaram maior consumo em relação as demais atletas. A média de ingestão de ferro das atletas das quatro modalidades fi cou a cima do recomendado. O vôlei foi a modalidade com maior porcentual de atletas com consumo excessivo de proteína e lipídio, e ingestão insuficiente de carboidrato em relação ao valor energético total. É importante a elaboração de programas de educação alimentar e o acompanhamento nutricional periódico de atletas adolescentes.


This study aims to investigate the nutritional quality of dietary composition of female adolescent athletes, comparing sports modalidities with different caracteristics as for energy expenditure and body weight control severity. This study included swimmers, volleyball players, olympic and artistic gymnasts, between 10 and 14 years old, from Grêmio Náutico União Club, Porto Alegre. Nutrient intake was based on 3-day food records. Macro- and Micro- nutrients intake was compared recommendations of World Health Organization and to Dietary References intake, respectively. We studied 45 athletes (13 swimmers, 17 volleyball players, 7 olympic gymnasts and 8 artistic gymnasts). The swimmers presented higher energy intake, approximately 1000kcal/day higher than the other sports. Swimmers and artistic gymnasts showed hogher carbohydrate intake per kilogram body weight than the other sports. The mean iron intake was higher than de recommendation for all athletes. The volleyball athletes showed higher prevalence of excessive protein and lipid intake and insufi cient carbohydrate intake. A nutrition educational program and periodical nutritional attendance of female adolescent athletes is necessary.

ABSTRACT

Ethical issues pertaining research and counseling in nutritional sciences will be arising in this new century. This issue will be of great importance especially in the area of nutraceutical supplementation and disease (pharmacological nutrition). Steps to insure bioethical correctness are discussed in this paper.
