Headteachers' and chairs of governors' perspectives on adolescent obesity and its prevention in English secondary school settings.

BACKGROUND: Secondary schools are an important setting for preventing obesity in adolescence. Headteachers and chairs of governors are identified in national guidance as crucial stakeholders for school-based preventative action. Despite this, their views remain unexplored and unrepresented. METHODS: A sequential mixed method study was conducted. Semi-structured interviews were undertaken with a purposive sample of 22 secondary school headteachers and chairs of governors in England. Data were thematically analysed and informed the development of a descriptive cross-sectional survey, completed by 127 participants from the same population. RESULTS: Unhealthy dietary and sedentary behaviours were viewed as a more significant problem than adolescent obesity. Obesity was perceived as complex and multi-causal, and a range of stakeholders were deemed to have responsibility for its prevention, most notably parents. Support was identified for the role of secondary schools, although this was not an explicit priority and extensive internal and external barriers exist, which hinder preventative action. CONCLUSIONS: Whilst secondary school settings in England remain an important setting for the prevention of adolescent obesity, it is crucial for policy makers and public health professionals to recognize the factors affecting school leaders' ability and willingness to contribute to this agenda.

Investigating the nutritional advice and support given to colorectal cancer survivors in the UK: is it fit for purpose and does it address their needs?

BACKGROUND: The present study assessed the quantity and quality of nutritional advice and support given to colorectal cancer survivors in the UK. METHODS: A descriptive cross-sectional survey was completed by 75 colorectal cancer survivors recruited through social media and bowel cancer support groups in the UK. The survey consisted of open-ended and closed questions that aimed to explore the nutritional needs, nutritional advice given and other sources of information accessed by colorectal cancer survivors. RESULTS: Sixty-nine percent of respondents reported that they did not receive any nutritional advice or support from their healthcare team throughout diagnosis, treatment and post-treatment. Colorectal cancer survivors accessed nutritional advice from a variety of sources, mainly cancer charity websites. Respondents expressed their desire for individualised advice relating to their nutritional problems. CONCLUSIONS: The results obtained in the present study indicate that a high proportion of colorectal cancer patients are not receiving the nutritional support that they need to overcome nutritional difficulties. There is an urgent need to improve clinical practice to ensure colorectal patients receive nutritional advice that is both consistent between healthcare professionals and personalised throughout each stage of diagnosis, treatment and post-treatment.

Nutrient intake and contribution of home enteral nutrition to meeting nutritional requirements after oesophagectomy and total gastrectomy.

BACKGROUND/OBJECTIVES: This study evaluated nutrition after oesophago-gastric resection and the influence of home jejunostomy feeding in the six months after surgery. SUBJECTS/METHODS: Data on nutritional intake and physiologic measures were collected as part of a randomised trial with measurements taken before and up to six months after surgery. RESULTS: A total of 41 participants (32 oesophagectomy, 9 total gastrectomy) received home jejunostomy feeding (n=18) or usual care without feeding (n=23). At hospital discharge, oral intakes were adequate for energy and protein in 9% and 6%, respectively. By three and six months, these values had increased to 61% and 55%, 94% and 77% respectively. Six participants (26%) who received usual care required rescue feeding. Six weeks after hospital discharge, energy intakes were met in those who received jejunal feeding because of the contribution of enteral nutrition. Jejunal feeding did not affect oral intake, being similar in both groups (fed: 77% estimated need, usual care: 79%). At three months, inadequate micronutrient intakes were seen in over one third. Compared to baseline values, six weeks after surgery, weight loss exceeding 5% was seen in 5/18 (28%) who received feeding, 14/17 (82%) who received usual care and 5/6 (83%) of those who required rescue feeding, P=0.002. Weight loss averaged 4.1% (fed), 10.4% (usual care) and 9.2% (rescue fed), P=0.004. These trends persisted out to six months. CONCLUSIONS: Supplementary jejunostomy feeding made an important contribution to meeting nutrition after oesophago-gastric resection. Importantly, oral nutritional intake was not compromised dispelling the assertion that jejunal feeding deincentivises patients from eating.

Exploring primary school headteachers' perspectives on the barriers and facilitators of preventing childhood obesity.

BACKGROUND: Headteachers of primary schools in England are a crucial partner for childhood obesity prevention. Understanding how this works in practice is limited by their views being underrepresented or missing from the evidence base. The aim of this study was to explore primary school headteachers' perspectives on childhood obesity and the perceived barriers and facilitators of prevention. METHODS: A qualitative study with a purposive sample of 14 primary school headteachers from the Yorkshire and Humber region of England was conducted. Semi-structured interviews were audio-taped, transcribed and analysed using an inductive thematic approach. RESULTS: An extensive range of barriers and facilitators emerged within four key themes; understanding childhood obesity, primary school setting, the role of parents and external partners. A lack of knowledge, awareness and skills to deal with the sensitivity and complexity of childhood obesity across all school stakeholders presents the most significant barrier to effective action. CONCLUSIONS: Headteachers recognize primary schools are a crucial setting for childhood obesity prevention; however their school's often do not have the capability, capacity and confidence to make a meaningful and sustainable impact. To increase headteachers' ability and desire to prevent childhood obesity, schools require specialist and tailored training, resources and support from external partners such as public health teams and school nursing services.

Investigating the use of the neutropenic diet: a survey of U.K. dietitians.

BACKGROUND: Patients with chemotherapy-induced neutropenia are at increased risk of infection. Historically, dietary restrictions commonly referred to as 'clean', 'low bacteria', 'low-microbial' or 'neutropenic' diets have been prescribed to reduce the risk of foodborne infection. Although research does not support their effectiveness, they continue to be used in clinical practice. The present study aimed to investigate the use of dietary restrictions in patients with cancer in the UK by surveying registered dietitians (RDs). METHODS: An online questionnaire was distributed to 573 RDs via local and specialist interest groups of the British Dietetic Association. RESULTS: One hundred and ten questionnaires were returned. Of these, 67.8% of RDs prescribed dietary restrictions to patients, with 'neutropenic diet' being the most commonly used term. Specialist oncology or haematology RDs were more likely to use the diet than nonspecialist RDs (P < 0.005). The variety of foods restricted varied greatly and was often contradicting. Unpasteurised dairy products and raw or lightly cooked meat or fish were most commonly restricted. Less than half (43.6%) of RDs had a policy in place for the use of neutropenic diets, with specialist oncology and haematology RDs more likely to report this (P < 0.005). CONCLUSIONS: Neutropenic dietary advice provided by dietitians in the UK varies greatly. Further high-quality research is required to create an evidence base from which national clinical guidelines can be formed.

Development and testing of a cancer appetite and symptom questionnaire.

BACKGROUND: Poor appetite and weight loss are common in patients with cancer, contributing to an increase in morbidity and mortality. Early identification of those at greatest risk is problematic. The Council on Nutrition Appetite Questionnaire (CNAQ) is short and easy to use, although it is not specific to cancer populations. The present study aimed to build on the CNAQ to develop a cancer appetite and symptom questionnaire (CASQ) for predicting weight loss in patients with cancer. METHODS: The content validity of the CNAQ was assessed by an expert panel (n = 41) using the content validity index (CVI). The resulting CASQ was tested for reliability among patients receiving radiotherapy (n = 34). Predictive validity of the CASQ was determined in patients with lung or upper gastrointestinal cancer (n = 185), comparing CASQ scores (possible range 0-48) recorded at baseline with percentage weight change after 12 weeks. RESULTS: In all but one CNAQ item, the CVI was above the minimum level of agreement (>0.70). Comments from expert panel members led to minor modifications and the introduction of new items resulting in the 12-item CASQ. The intraclass correlation coefficient of the CASQ was 0.80 [95% confidence interval (CI) = 0.68-0.92] and the difference between total scores at two time points was -0.20 (95% CI = -1.21 to 0.80). The optimum cut-off point of the instrument to predict >10% weight loss was 29/30 (area under curve = 0.75; sensitivity 71%, specificity 66%, positive predictive value 19%, negative predictive value 95%) [Correction added on 30 April 2012, after first online publication: in the preceding sentence, <10% was corrected to >10%]. CONCLUSIONS: The CASQ can predict weight loss among patients with lung and upper gastrointestinal cancer. Acknowledgment of the low positive predictive value is needed if the instrument is to be used within clinical practice.
