Informing the public health     

G Birkenhead  MJ Grant 《Health information and libraries journal》2012,29(3):177-179

Why with an increase in the amount of health information, and ways of accessing it, so many people experience poor health? What is the role of health library and information professionals in improving public health? These questions are of great interest to me. There are many examples of initiatives, particularly in the public library sector, which address health issues, however they are often very local and best practice is not always shared. Clearly changing the health status of a population requires more than information, but information is clearly an essential component. If health information is to be effective in improving public health then we need to address health literacy, and this is where health library and information professionals can play a significant role. Through this journal and the other activities of the Health Libraries Group I hope we can share good practice and explore new ways that health library and information workers can improve the health of individuals and communities.  相似文献   

Bardet–Biedl Syndrome: A Rare Cause of Chronic Kidney Disease

Bardet-Biedl syndrome (BBS) is a rare autosomal recessive condition characterized by retinitis pigmentosa, postaxial polydactyly, central obesity, and renal involvement. Renal failure is the commonest cause of death. We report a case of BBS with chronic kidney disease (CKD) at younger age (17 year) from India. This diagnosis should be considered in patients with renal disease and the characteristic phenotype of retinitis pigmentosa, postaxial polydactyly and central obesity. These patients should undergo regular monitoring of renal function test to early diagnosis and treatment of CKD to prevent morbidity and mortality. Renal transplantation is a viable option of renal replacement therapy in these patients. These findings are valuable for comparing phenotype of BBS patients with CKD from various national and international centers.  相似文献

The effect of pedometer use on physical activity and body weight in obese women     

《European Journal of Sport Science》2013,13(4):351-356

Abstract

Physical activity and healthy eating are of the utmost importance in treatment of obesity. However obese generally tend to have a sedentary lifestyle. Walking is a form of physical activity that is both simple and can be performed by everyone, but it requires an objective measurement. Number of steps taken during tracking can be recorded with the pedometer, a device used to measure the level of physical activity. We aimed to investigate whether or not using pedometers as a motivational technique to increase the level of physical activity in obese women has an impact on weight loss. Eighty-four obese women who are similar age referring to Ataturk University Faculty of Medicine Healthy Living Clinic, Turkey were randomly divided into two groups. Intervention group were given pedometers, and control group were prescribed similar diet and physical activity with a three-month follow-up plan without pedometers. Mean weight in pedometer group initially was 88.9 ± 8.4 kg, which decreased to 80.2 ± 8.7 kg after the programme. Mean weight in control group was 86.1 ± 9.2 kg at the beginning, and it decreased to 84.7 ± 8.8 kg after three months. It was observed in pedometer group that the mean number of steps 8817 ± 2725 steps/day at the beginning increased to mean 9716 ± 2811 steps/day at the end of the study. Weight, body mass index, body fat percentage and waist circumference measurements decreased more greatly in the pedometer when compared to the control group (p < 0.001). Pedometers may be recommended to obese patients to monitor and increase the level of physical activity and to promote weight loss.  相似文献

Effects of Aerobic Exercise on Overweight Children's Cognitive Functioning     

Catherine L. Davis  Phillip D. Tomporowski  Colleen A. Boyle  Jennifer L. Waller  Patricia H. Miller  Jack A. Naglieri 《Research quarterly for exercise and sport》2013,84(5):510-519

The study tested the effect of aerobic exercise training on executive function in overweight children. Ninety-four sedentary, overweight but otherwise healthy children (mean age = 9.2 years, body mass index ? 85th percentile) were randomized to a low-dose (20 min/day exercise), high-dose (40 min/day exercise), or control condition. Exercise sessions met 5 days/week for 15 weeks. The Cognitive Assessment System (CAS), a standardized test of cognitive processes, was administered individually before and following intervention. Analysis of covariance on posttest scores revealed effects on executive function. Group differences emerged for the CAS Planning scale (p = .03). Planning scores for the high-dose group were significantly greater than those of the control group. Exercise may prove to be a simple, yet important, method of enhancing aspects of children's mental functioning that are central to cognitive and social development.  相似文献   

Evolution of fat oxidation during exercise in obese pubertal boys: Clinical implications     

Gautier Zunquin  Denis Theunynck  Bruno Sesboüé  Pierre Arhan  Dominique Bouglé 《Journal of sports sciences》2013,31(4):315-318

Abstract

In this study, we examined fat oxidation rates during exercise in obese pubescent boys. Three groups of pubescent boys (16 pre-pubescent, Tanner's stage I; 16 pubescent, Tanner's stage III; and 14 post-pubescent, Tanner's stage V) performed a graded test on a leg cycle ergometer. The first step of the test was fixed at 30 W and power was gradually increased by 20 W every 3.5 min. Oxygen consumption ([Vdot]O₂) and carbon dioxide production ([Vdot]CO₂) were determined as the means of measurements during the last 30 s of each step, which allowed us to calculate fat oxidation rates versus exercise intensity. Between 20 and 50% of peak oxygen consumption ([Vdot]O_2peak), fat oxidation rate in relative values (mg · min^?1 · kg FFM^?1) decreased continuously with pubertal development. In the same way, the maximum rate of fat oxidation occurred at a lower percentage of [Vdot]O_2peak (pre-pubescent: 49.47 ± 1.62%; pubescent: 47.43 ± 1.26%; post-pubescent: 45.00 ± 0.97%). Our results confirm that puberty is responsible for a decrease in fat free mass capacities to use fat during exercise. The results suggest that post-pubescent obese boys need to practise physical activity at a lower intensity than pre-pubescent boys to enhance lipolysis and diminish adipose tissue and the consequences of obesity.  相似文献   

Prediction of habitual physical activity level and weight status from fundamental movement skill level     

Elizabeth Sarah Bryant  Rob S. James  Samantha Louise Birch  Mike Duncan 《Journal of sports sciences》2013,31(19):1775-1782

Abstract

Fundamental movement skills (FMS) have been assessed in children in order to investigate the issues of the low proportion of children who meet physical activity (PA) guidelines and rising levels of obesity. The aim of this research was to identify whether previous or current FMS level is a better predictor of PA levels and weight status in children. In January 2012 (year 1), 281 children were recruited from one primary school in the West Midlands, UK. Children performed eight FMS three times, which were videoed and assessed using a subjective checklist. Sprint speed and jump height were measured objectively. Height and mass were measured to calculate the body mass index to determine the weight status. Skinfold calliper readings were used to calculate body fat percentage. One year later, in January 2013, all these tests were repeated on the same children, with the additional collection of PA data via the use of pedometers. Following multiple linear regression, it was identified that prior mastery in FMS was a better predictor of current PA, whereas current FMS was a better predictor of current weight status. Overall, FMS mastery is needed in childhood to be able to participate in PA and maintain a healthy weight status.  相似文献

Childhood obesity: psychosocial outcomes and the role of weight bias and stigma     

Pauline V. Bromfield 《Educational Psychology in Practice》2009,25(3):193-209

Research, policy and media discourses highlight negative physical and non‐physical outcomes for overweight/obese children and adolescents compared with their non‐overweight/obese peers. The research findings that have positioned this “vulnerable” group are reviewed with particular reference to the desired outcomes of the Every Child Matters agenda. The mediating role of weight bias and stigma is also explored. The relevance of these issues with regard to educational psychology service delivery priorities is also considered. A key question is how educational psychologists position themselves in relation to challenging some of the discourses alongside providing support for children, families, schools, and other service providers for whom the phenomenon of childhood obesity is a concern.  相似文献
