Physical activity, weight status and diet in adolescents: are children meeting the guidelines  [PDF]
Spencer E. Boyle, Georgina L. Jones, Stephen J. Walters
Health (Health) , 2010, DOI: 10.4236/health.2010.210167
Abstract: Childhood obesity is on the increase and maintaining regular physical activity and consuming a healthy diet have become essential tools to combat the condition. The United Kingdom government has recommended guidelines for optimal levels of diet and activity in children. The aim of this paper is to describe and compare self-reported physical activity levels, diet, and Body Mass Indices (BMI) amongst adolescent children, aged 11-15, in the South West (SW) and North West (NW) regions of England and to see if these children were meeting the current targets for optimal levels of: physical activity; fruit/vegetable consumption; fat consumption and BMI. We report the results of a cross-sectional survey of four secondary schools and 1,869 children using the self-reported Western Australian Child and Adolescent Physical Activity and Nutrition Survey (CAPANS) physical activity instrument and a food intake screener questionnaire, in summer and winter. We found that 25% (469/1869) 95% CI: 23% to 27%, of children engaged in 60 minutes of moderate to vigorous physical activity per day; 53% (995/1866) 95% CI: 51% to 56%, took 5 portions of fruit and vegetables per day; while 22% (407/1861) 95% CI: 20% to 24% consumed recommended amount of fats, and 23.7% (276/1164) 95% CI: 21% to 26%, of pupils were obese or overweight as classified by their BMI. Self reported physical activity in young people regardless of area is lower than previously reported and the lack of students engaging in 60 minutes moderate to vigorous activity could have serious public health consequences. If sustained, this could lead to more overweight adults, and more ill health.
Physical activity among adolescents and barriers to delivering physical education in Cornwall and Lancashire, UK: A qualitative study of heads of PE and heads of schools
Spencer Boyle, Georgina L Jones, Stephen J Walters
BMC Public Health , 2008, DOI: 10.1186/1471-2458-8-273
Abstract: Seventeen semi-structured qualitative interviews were carried out with a snowball sample of HOPE and HS in schools in the Northwest and Southwest of England. Thematic data analysis using NVIVO was used to identify emergent themes.17 core themes were generated, 12 of which confirmed the findings from similar research. However, five themes relating to 'ethos of performance/elitism', 'lower fitness leads to lower ability', 'undervaluing activities within PE dept' or school as a whole', 'role of the school' and 'PE department doing all it can' offer valuable new insight into the factors which may encourage or prevent PA inside or outside the curriculum.Despite many positive perceptions of the delivery of PE in schools, it is evident that barriers still exist within that delivery which discourages physical activity. More research is needed to particularly address the complex issues of elitism and the ethos of PA in schools.Recent data indicate that almost one in four young people in the UK (23.7% of 11–15 year old males and 26.2% females) are now classed as obese [1]. There is much speculation about the causes of obesity in young adolescents. However, it has been reported that one of the leading contributory factors of childhood obesity is a lack of physical activity (PA) [1]. Although a common standard of the optimum level of young people's physical activity has yet to be universally agreed upon [2], the UK government (as part of its physical education school sports club links strategy), set a target in 1999 that 85% of school children should take part in two hours per week of high quality sport and physical education (PE) and a variety of new initiatives were introduced in schools to help children achieve this target by 2008 [3].Nevertheless, despite these new initiatives there is still controversy amongst physical educators and academics over whether young people are obtaining adequate levels of PE and are sufficiently physically active. For example, according to a Sp

Abstract: The PedsQL 4.0 was administered to children receiving blood transfusions and treatments at Hospital Kuala Lumpur, Malaysia using PedsQL 4.0 generic Scale Score. Accordingly, the questionnaire was also administered to a control group of healthy school children. Socio-demographic data were also collected from patients and controls using an interview schedule designed for the study.Of the 96 thalassaemia patients approached, 78 gave consent to be interviewed giving a response rate of 81.3%. Out of 235 healthy controls approached, all agreed to participate giving a response rate of 100%. The mean age for the patients and schoolchildren is 11.9 and 13.2 years respectively. The age range for the patients and the schoolchildren is between 5 to 18 years and 7 to 18 years respectively. After controlling for age and demographic background, the thalassaemia patients reported having significantly lower quality of life than the healthy controls.Thalassaemia has a negative impact on perceived physical, emotional, social and school functioning in thalassaemia patients which was also found to be worse than the children's healthy counterparts. Continuing support of free desferal from the Ministry of Health should be given to these patients. More understanding and support especially from health authorities, school authorities and the society is essential to enhance their quality of life.Thalassaemia is a genetic blood disorder which can be fatal if proper treatment is not received. It is characterised by partial or no production of alpha or beta globin chains which form part of the structure of the haemoglobin in the red blood cells [1]. Thalassaemia is an increasingly serious public health problem throughout the Mediterranean region, the Middle East, the Indian subcontinent and South East Asia [2,3]. In Malaysia, it occurs mainly in the Malays and Chinese Malaysians [4]. The Ministry of Health of Malaysia estimated that between 150 and 350 babies are born with thalassaemia each year

Abstract: The Polycystic Ovary Syndrome Questionnaire (PCOSQ) and the Short Form-36 (SF-36) were administered in a cross-sectional survey to 42 South Asian and 129 Caucasian women diagnosed with PCOS recruited from the gynaecology outpatient clinics of two university teaching hospitals in Sheffield and Leeds. Additional clinical data was abstracted from medical notes. Normative data, collected as part of the Oxford Health and Lifestyles II survey, was obtained to compare SF-36 results with ethnically matched women from the general UK population. Using the SF-36, normative HRQoL scores for women of South Asian origin were lower than for Caucasian women. Given this lower baseline we tested whether the same relationship holds true among those with PCOS.Although HRQoL scores for women with PCOS were lower than normative data for both groups, South Asian women with PCOS did not have poorer HRQoL than their Caucasian counterparts. For both the SF-36 and PCOSQ, mean scores were broadly the same for both Asian and Caucasian women. For both groups, the worst two HRQoL domains as measured on the PCOSQ were 'infertility' and 'weight', with respective scores of 35.3 and 42.3 for Asian women with PCOS compared to 38.6 and 35.4 for Caucasian women with PCOS. The highest scoring domain for South Asian women with PCOS was 'menstrual problems' (55.3), indicating best health, and was the only statistically significant difference from Caucasian women (p = 0.01). On the SF-36, the lowest scoring domain was 'Energy & Vitality' for Caucasian women with PCOS, but this was significantly higher for Asian women with PCOS (p = 0.01). The best health status for both groups was 'physical functioning', although this was significantly lower for South Asian women with PCOS (p = 0.005). Interestingly, only two domains differed significantly from the normative data for the Asian women with PCOS, while seven domains were significantly different for the Caucasian women with PCOS compared to their normative coun

Abstract: Oomycete pathogens cause diverse plant diseases. To successfully colonize their hosts, they deliver a suite of effector proteins that can attenuate plant defenses. In the oomycete downy mildews, effectors carry a signal peptide and an RxLR motif. Hyaloperonospora arabidopsidis (Hpa) causes downy mildew on the model plant Arabidopsis thaliana (Arabidopsis). We investigated if candidate effectors predicted in the genome sequence of Hpa isolate Emoy2 (HaRxLs) were able to manipulate host defenses in different Arabidopsis accessions. We developed a rapid and sensitive screening method to test HaRxLs by delivering them via the bacterial type-three secretion system (TTSS) of Pseudomonas syringae pv tomato DC3000-LUX (Pst-LUX) and assessing changes in Pst-LUX growth in planta on 12 Arabidopsis accessions. The majority (~70%) of the 64 candidates tested positively contributed to Pst-LUX growth on more than one accession indicating that Hpa virulence likely involves multiple effectors with weak accession-specific effects. Further screening with a Pst mutant (ΔCEL) showed that HaRxLs that allow enhanced Pst-LUX growth usually suppress callose deposition, a hallmark of pathogen-associated molecular pattern (PAMP)-triggered immunity (PTI). We found that HaRxLs are rarely strong avirulence determinants. Although some decreased Pst-LUX growth in particular accessions, none activated macroscopic cell death. Fewer HaRxLs conferred enhanced Pst growth on turnip, a non-host for Hpa, while several reduced it, consistent with the idea that turnip's non-host resistance against Hpa could involve a combination of recognized HaRxLs and ineffective HaRxLs. We verified our results by constitutively expressing in Arabidopsis a sub-set of HaRxLs. Several transgenic lines showed increased susceptibility to Hpa and attenuation of Arabidopsis PTI responses, confirming the HaRxLs' role in Hpa virulence. This study shows TTSS screening system provides a useful tool to test whether candidate effectors from eukaryotic pathogens can suppress/trigger plant defense mechanisms and to rank their effectiveness prior to subsequent mechanistic investigation.

Profile Issues in Teachers` Professional Development , 2009,
Abstract: whilst communicative teaching approaches sanction, often grudgingly, the limited use of the students' first language (l1) in english language teaching (elt), critical debate is now centred on a much more substantial and energetic role for the use of mother tongue in the language classroom. justifications favouring the use of l1 currently range from ideological arguments to classroom teaching considerations. this paper contributes to this ongoing debate by examining how new generations of language teachers in mexico are using the students' mother tongue, spanish, not only as a pedagogical tool but to develop and reinforce interpersonal relationships in the language classroom in order to enhance the learning of english.

Abstract: Whilst communicative teaching approaches sanction, often grudgingly, the limited use of the students’ first language (l1) in English Language Teaching (elt ), critical debate is now centred on a much more substantial and energetic role for the use of mother tongue in the language classroom. Justifications favouring the use of l1 currently range from ideological arguments to classroom teaching considerations. This paper contributes to this ongoing debate by examining how new generations of language teachers in Mexico are using the students’ mother tongue, Spanish, not only as a pedagogical tool but to develop and reinforce interpersonal relationships in the language classroom in order to enhance the learning of English. Key words: First language, critical pedagogy, phatic communion Mientras que los métodos comunicativos de ense anza autorizan, muchas veces con poco entusiasmo, el uso de la lengua materna (l1) de los estudiantes del idioma inglés (ei), un gran debate propone un papel más sustancial y activo para el uso del espa ol en el salón de clases. Actualmente, los argumentos que se muestran a favor del uso de la lengua materna (l1) parten desde motivos ideológicos hasta factores pedagógicos en la ense anza en el salón de aprendizaje de idiomas. El presente artículo contribuye a este debate en curso examinando la forma en que las nuevas generaciones de profesores de inglés en México están utilizando la lengua materna de sus estudiantes, el espa ol, no sólo como una herramienta pedagógica sino para desarrollar y reforzar las relaciones interpersonales en el salón de idiomas, de forma que el aprendizaje del inglés se vea favorecido.
