Fiabilidad y validez del cuestionario SAPF y del pictograma de Stunkard en población mayor española / Reliability and validity of the SAPF questionnaire and the Stunkard rating scale amongst elderly Spanish people

Fundamento: El objetivo de este estudio fue identificar lafiabilidad y validez del cuestionario SAPF y del pictogra-ma de Stunkard para conocer la forma física autopercibi-da y el grado de insatisfacción corporal en un grupo depersonas mayores españolas. Método: Ambos instrumentos se adaptaron al castellanoy se administraron dos veces a un grupo de 86 personasmayores. Su fiabilidad y validez se evaluaron con el ín-dice de correlación intraclase (CCI), el alfa de Cronbachy el coeficiente rho de Spearman, a partir del nivel deforma física de los participantes y de su índice de masacorporal (IMC). La comparación de las variables con dis-tribución normal se realizó mediante ANOVA. Resultados: El cuestionario y el pictograma mostraronuna buena fiabilidad test-retest (CCI = 0,78 y CCI = 0,8respectivamente). La puntuación del SAPF y el nivel deforma física mostraron asociación débil (rho = 0,424) yla autopercepción de la propia composición corporaly el IMC, moderadamente fuerte (rho = 0,727). La formafísica autopercibida del 59,5 % de la muestra fue nor-mal, del 11,4 % mala y del 29,1 % buena. Solo el 27,06 %se mostró satisfecho con su imagen corporal, el restomostró su deseo de bajar de peso el equivalente a uno(47,1 %), dos (22,4 %) o tres o más puntos (3,5 %) en elpictograma. Conclusiones: La adaptación al castellano de los dos ins-trumentos mostró fiabilidad y validez, permitiendo cono-cer que gran parte de la muestra se mostró insatisfechacon su imagen corporal, aspecto sobre el que el IMC ejer-ció una influencia significativa

Background: The aim of the study was to identify the re-liability and validity of the SAPF questionnaire and theStunkard rating scale in determining self-perceived phys-ical appearance and the degree of body dissatisfaction ina group of elderly Spanish people. Methods: Both instruments were adapted to Spanishpeople and were administered twice to a group of 86 el-derly people. Their reliability and validity were assessedby means of the intraclass correlation coefficient (ICC),Cronbach’s alpha and Spearman’s rho coefficient, fromthe physical fitness level of the participants and theirbody mass index (BMI). ANOVA test was carried out tocompare the variables with normal distribution. Results: The questionnaire and the Stunkard ratingscale showed a good test-retest reliability (ICC = 0.78 andICC = 0.8, respectively). SAPF and fitness level showed asignificant, albeit weak, association (rho = 0.424), while theassociation between self-perception of body compositionand BMI was moderately strong (rho = 0.727). The self-per-ceived physical appearance of 59.5 % of the sample wasacknowledged to be normal, 11.4 % perceived it as bad and29.1 % as good. Only 27.1 % were satisfied with their bodyimage, while the other participants showed a desire tolose the equivalent weight of one (47.06 %), two (22.35 %)or three or more (3.5 %) points in the Stunkard scale. Conclusion: The versions of both instruments adaptedto Spanish persons showed reliability and validity, andshowed that it was possible to determine that a large partof the sample was dissatisfied with their body image. BMIhad a significant influence in this regard.(AU)

Association between maximal oxygen consumption and physical activity and sedentary lifestyle in metabolic syndrome. Usefulness of questionnaires.

INTRODUCTION AND OBJECTIVES: To analyze whether variations in physical activity (PA) and sedentary behaviors are accompanied by differences in maximal oxygen consumption (VO2max). METHODS: We conducted a prospective cross-sectional study of 243 participants (82 women), aged 65.0±4.9 years old, with metabolic syndrome and overweight/obesity who performed a maximal exercise test with expired gas analysis. PA was evaluated using subjective methods, the REGICOR and RAPA 1 self-reported questionnaires, and objective methods, the chair test and accelerometry. Sedentariness was analyzed with the Nurses' Health Study questionnaire and accelerometry. RESULTS: VO2max was higher in participants who reported they adhered to the recommendations of the PA guidelines in the REGICOR questionnaire (21.3±4.6 vs 18.0±4.4 mL/kg/min; P <.001) and was 18% higher in those who reported more PA in the RAPA 1 questionnaire than the less active group (P <.001). The chair test (> 15 vs ≤ 15 repetitions) also showed significant differences in VO2max (21.2±4.8 vs 18.7±4.5 ml/kg/min; P <.001). Correlations between PA variables and VO2max were significant but low (r: 0.2 to 0.4). Sedentary activities showed less relationship with VO2max. CONCLUSIONS: Participants with metabolic syndrome and overweight/obesity who reported adhering to PA recommendations achieved higher VO2max. The self-reported questionnaires and the chair test identified significant variations in VO2max. Sedentary activities do not appear to modify VO2max.

[Fitness and quality of life in kidney transplant recipients: case-control study]. / Forma física y calidad de vida en pacientes trasplantados de riñón: estudio de casos y controles.

BACKGROUND AND OBJECTIVES: We analyzed the levels of fitness, muscle structure and quality of life of adults after kidney transplant and healthy adults. PATIENTS AND METHODS: A total of 16 kidney transplant patients and 21 healthy controls performed several fitness test, isokinetic evaluation of knee flexion and extension and ultrasonography muscle thickness assessment. They also completed the quality of life questionnaire SF-36. RESULTS: Physical fitness, muscle structure and quality of life of the kidney transplant recipients were significantly poorer than the controls. The transplant patients performed less well in the "get up and go" and "sit to stand" test (p<.001) as well as in assessments of muscle structure, strength and power. The patients had a poorer score in their quality of life assessments, differing from the controls in domains of physical function, physical role, general health and social function (p<.001). DISCUSSION: Fitness, strength and muscle mass are diminished in kidney transplant patients, resulting in a poorer quality of life which might entail an increased risk to their health.

[Physical activity, physical fitness, and overweight in children and adolescents: evidence from epidemiologic studies]. / Actividad física, condición física y sobrepeso en niños y adolescentes: evidencia procedente de estudios epidemiológicos.

Physical activity and fitness play a significant role in prevention of overweight and obesity in children and adolescents. Current understanding and evidence from epidemiologic studies provide useful insights to better understand how they relate to each other and how to develop future intervention strategies. This paper summarizes the most relevant information from cross-sectional and longitudinal studies on the relationships between physical activity, physical fitness, and overweight in early life. According to current scientific evidence: (i) High levels of physical activity during childhood and adolescence, particularly vigorous physical activity, are associated to lower total and central adiposity at this age and later in life; (ii) the level of physical fitness, especially aerobic fitness, is inversely related to current and future adiposity levels; (iii) overweight children and adolescents with a high fitness level have a healthier cardiovascular profile than their overweight, low fit peers and a similar profile to their normal weight, low fit peers. This suggests that high fitness levels may counteract the negative consequences attributed to body fat. These findings suggest that increasing physical fitness in overweight children and adolescents may have many positive effects on health, including lower body fat levels.

Efeito da peletização e adição de enzimas e vitaminas sobre o desempenho e aproveitamento da energia e nutrientes em frangos de corte de 1 a 21 dias de idade / Effect of pelleting and addition of enzymes and vitamins on the performance and advantage of energy and nutrients in broiler chickens from 1 to 21 days old

Conduziu-se este experimento para avaliar o efeito da peletização e adição de enzimas e vitaminas sobre o desempenho e aproveitamento da energia e nutrientes, em frangos de corte de 1 a 21 dias de idade. Foram utilizados 350 pintos de corte, COBB, machos, com peso inicial médio de 47g ± 2,5g, em um delineamento inteiramente casualizado, com os tratamentos em arranjos fatorial 3 x 2 (três dietas, com e sem enzimas) sendo que as dietas consistiram de uma ração farelada e duas rações peletizadas,uma com adição de vitaminas e minerais após a peletização e a outra com adição de vitaminas e minerais antes da peletização. O tempo e a temperatura da peletizadora variaram de 05 a 09 minutos e 58ºC a 62ºC, respectivamente. Após esse processo, as rações peletizadas foram trituradas, buscando-se manter a mesma granulometria das rações fareladas. O ensaio de desempenho foi realizado com 10 repetições e o de metabolismo com 5 repetições cada tratamento, em uma densidade de 5 aves por parcela (gaiola). As rações foram formuladas com 95 por cento das recomendações nutricionais e fornecidas às aves com uma restrição alimentar de, aproximadamente, 10 por cento do consumo ad libitum, o qual foi calculado diariamente a partir do consumo médio de um grupo de aves controle, que foram submetidas ao consumo à vontade de uma ração formulada para atender 100 por cento dos níveis nutricionais recomendados. O complexo enzimático utilizado foi o Allzyme Vegpro®, contendo em sua composição as enzimas protease, amilase e celulase, adicionado aos tratamentos seguindo as recomendações do fabricante, de 0,5 kg por tonelada de ração. Aos 21 dias de idade avaliou-se o ganho de peso e a conversão alimentar. Também foram coletadas as excretas, pela metodologia de coleta total de excretas, nos dias 20, 21 e 22, para determinação dos valores energéticos das rações e digestibilidade da gordura e da proteína. Pelos resultados obtidos, observou-se que o ganho de peso, a conversão...

It was carried out an experiment to evaluate the effect of pelleting and addition of enzymes and vitamins on the performance and advantage of energy and nutrients in broiler chickens from 1 to 21 days old. A total of 350 broiler chickens, COBB, males, were used ( (47g ± 2.5g) in a completely randomized design, with the treatments in a 3 x 2 factorial arrangement (three diets with or without enzymes) and (two diets based on corn and soybean one meal two pelleted , with or without addition of vitamins and minerals after pelleting and the other with addition of vitamins and minerals before pelleting. The time and temperature of pelleting ranged from 5 to 9 minutes and 58ºC to 62ºC, respectively. After this process, the pelleted rations were ground with the same particle size similar to meal rations. In the performance assay were utilized 10 replicates and the of metabolism assay it was with 5 replicates in each treatment with density of 5 chickens per plot (cage). The diets were formulated with 95 percent of the nutritional recommendations and the chickens were fed with in a feed restriction of 10 percent from ad libitum intake, which was calculated daily from the average intake of a group of chickens control , which were submitted to ad libitum intake of a diet formulated with 100 percent of the nutritional levels recommended. The enzyme complex utilized was Allzyme Vegpro®, containing the enzymes protease, amylase and cellulase, which were added to the treatments following the manufacturer's recommendations, of 0.5 kg per ton of ration. At final of 21 days old, weight gain and feed conversion were evaluated. The excreta were collected by the methodology of total collection in the 20, 21 and 22 days to determination of the energetics values of the diets and as well as the ether extract and protein digestibility coefficients. The weight gain, feed conversion, corrected apparent metabolizable energy and coefficient of digestibility of...
