  • Impact of community dietetic leadership in paediatric food allergy on the burden of care for both primary care and families: A service evaluation comparison

    Freeman-Hughes, Amy (2022)
    Objectives: Food allergy is common in infants and young children and symptoms overlap with other common gastrointestinal disorders and atopic conditions, all impacting on primary care practitioner (GP) workload. This project aimed to describe the potential benefits of a dietetic-led allergy service to support this. Method: Between October 2019 and July 2020, two dietetic services for children aged 0-11 years referred with food allergy were compared. One is a dietetic-led service where dietitians train community children's nurses (0-19 team) to recognize potential cases of food allergy. The second is a traditional model of dietetic community care, obtaining referrals from GPs and secondary care. Ethical approval was obtained. Results: In the dietetic-led service 86 patients were seen [80% non-IgE cow's milk allergy) CMA)], of which 62% were referred by the 0-19 team. In the community service 96 patients were seen (85% non-IgE CMA), of which 27% were referred by the 0-19 team and 67% from GPs. 78% of children referred to the dietetic-led service were under 6 months of age, compared to 40% in the community service, where 34% were over 1 year. Hypoallergenic formula was first prescribed at a mean age of 9.4 weeks in dietetic-led vs 13.9 weeks in community care. Patient contacts with GPs prior to referral was 3 vs 6 visits (p = 0.001) and input from secondary care was also lower (8 vs 25 patients; p = 0.002) in dietetic-led vs community services respectively. There were similar numbers of patient contacts with the 0-19 team in both services (median 2). A substantial reduction in prescription of medications occurred following diagnosis (Figure 1). Conclusions: Real-world data highlight that a dietetic-led paediatric service can relieve the burden of care of food allergy in primary care, empowering community children's nurses as part of integrated care system working.
  • Feasibility and acceptability of a dietary intervention to reduce salt intake and increase high-nitrate vegetable consumption in Malaysian middle-aged and older adults with elevated blood pressure: Findings from the DePEC-Nutrition trial

    Stephan, Blossom C. M. (2022)
    The DePEC-Nutrition trial is a complex dietary and behavioural intervention of salt intake reduction combined with increased high-nitrate vegetable consumption among Malaysian middleaged and older adults with elevated blood pressure. This study aimed to assess the feasibility and acceptability of the trial. Participants were recruited from the South East Asia Community Observatory (SEACO) database and randomised into one of four groups: (1) low salt; (2) high-nitrate vegetable; (3) combined high-nitrate vegetable and low salt; and (4) control. The intervention included a combination of group counselling sessions, information booklets, reinforcement videos and text messages to modify dietary behaviour. The primary outcomes evaluated were the measures of feasibility and acceptability of (1) recruitment, follow-up attendance and retention; (2) data collection procedures and clinical outcome measures; and (3) individual and combined multi-modal dietary interventions. A total of 74 participants were recruited, and the 10-month retention rate was 73%. Data collection procedures were acceptable with minimal missing data. All intervention strategies were feasible and acceptable, with group counselling being the most acceptable strategy. This study provides important insights into improving the screening process of participants, facilitating their access to the research facilities and refining the measurement protocols and dietary recommendations, which are instrumental in formulating the design of a full-scale definitive DePEC-Nutrition trial. © 2022 by the authors.

  • Nutritional interventions in older people with COVID-19: an overview of the evidence

    Archer, Elizabeth (2021)
    Older people are a high-risk group for coronavirus disease 2019 (COVID-19) because of a range of factors, including age-related changes in anatomical pulmonary and muscle function, decreased immunity and increased inflammation. These factors partly explain why older people with COVID-19 experience more severe symptoms and higher mortality than younger adults and are more likely to require nutritional support. Furthermore, there is an association between suboptimal nutritional status and poorer recovery from COVID-19. Therefore, nutritional interventions are an important aspect of care for older people with COVID-19. All members of the multidisciplinary team, including dietitians and nurses, need to assess, treat and prevent nutritional deficiencies in older people with COVID-19. This literature review provides an overview of the evidence regarding the role of nutritional interventions in the treatment of, and recovery from, COVID-19 in older people.
  • Sarcopenic obesity is associated with telomere shortening: findings from the NHANES 1999-2002

    Stephan, Blossom C. M. (2021)
    Sarcopenic obesity (SO) is characterised by the concurrent presence of sarcopenia and excess adiposity. Telomere shortening has been associated with sarcopenia and obesity alone but the association between SO and telomere length (TL) has not been investigated. This study aimed to investigate SO and TL in an adult population. Data were from 5397 individuals (mean age = 44.7 years, 51.3% male) enrolled in the National Health and Nutrition Examination Survey. Body composition (BC) was assessed by Dual Energy X-Ray Absorptiometry. Two models were used to assess SO: a BC model including four phenotypes derived from the combination of high or low adiposity and muscle mass; and, a truncal fat mass to appendicular skeletal mass ratio (TrFM/ASM). TL was assessed using quantitative polymerase chain reaction and expressed as base pairs. The mean TL, relative to the reference DNA, was calculated and expressed as the mean T/S ratio. A General Linear Model was applied to determine associations between TL for SO. In adjusted analysis, only individuals with SO, defined as the presence of high adiposity-low muscle mass (four-phenotype model), had significantly shorter telomeres (p = 0.05) than the reference group (i.e. low adiposity-high muscle mass), with a mean T/S ratio of 1.02 (95%CI: 0.98–1.05) compared to 1.05 (95%CI: 1.01–1.09), respectively. TrFM/ASM was not associated with TL. Preliminary findings suggest that sarcopenia and obesity may act synergistically to shorten telomeres.
  • Mediterranean diet and cognitive function: From methodology to mechanisms of action

    Stephan, Blossom C. M. (2021)
    The traditional Mediterranean diet (MedDiet), rich in minimally processed plant foods and fish, has been widely recognized to be one of the healthiest diets. Data from multiple randomized clinical trials have demonstrated its powerful effect against oxidative stress, inflammation and the development and progression of cardiovascular disease, type 2 diabetes, and other metabolic conditions that play a crucial role in the pathogenesis of neurodegenerative diseases. The protecting effects of the MedDiet against cognitive decline have been investigated in several observational and experimental studies. Data from observational studies suggest that the MedDiet may represent an effective dietary strategy for the early prevention of dementia, although these findings require further substantiation in clinical trials which have so far produced inconclusive results. Moreover, as we discuss in this review, accumulating data emphasizes the importance of: 1) maintaining an optimal nutritional and metabolic status for the promotion of healthy cognitive aging, and 2) implementing cognition-sparing dietary and lifestyle interventions during early time-sensitive windows before the pathological cascades turn into an irreversible state. In summary, components of the MedDiet pattern, such as essential fatty acids, polyphenols and vitamins, have been associated with reduced oxidative stress and the current evidence from observational studies seems to assign to the MedDiet a beneficial role in promoting brain health; however, results from clinical trials have been inconsistent. While we advocate for longitudinal analyses and for larger and longer clinical trials to be conducted, we assert our interim support to the use of the MedDiet as a protective dietary intervention for cognitive function based on its proven cardiovascular and metabolic benefits.
  • Safety of antidepressants in a primary care cohort of adults with obesity and depression

    Morriss, Richard K. (2021)
    BACKGROUNDObesity, depressive disorders and antidepressant drugs are associated with increased mortality, cardiovascular disease, diabetes, fractures and falls. We explored outcomes associated with the most commonly prescribed antidepressants in overweight or obese people with depression.METHODS AND FINDINGSWe identified a cohort of overweight or obese adults (≥18 years) in primary care from the UK Clinical Practice Research Datalink, linked with hospital and mortality data, between 1 January 2000 and 31 December 2016 who developed incident depression to January 2019. Cox proportional hazards models and 99% confidence intervals were used to estimate hazard ratios (HR) for mortality, cardiovascular disease, diabetes, and falls/fractures associated with exposure to selective serotonin reuptake inhibitors (SSRIs), tricyclic (TCA)/other, combination antidepressants, citalopram, fluoxetine, sertraline, amitriptyline and mirtazapine, adjusting for potential confounding variables. In 519,513 adults, 32,350 (9.2 per 1,000 years) displayed incident depression and 21,436 (66.3%) were prescribed ≥1 antidepressant. Compared with no antidepressants, all antidepressant classes were associated with increased relative risks of cardiovascular disorders [SSRI HR: 1.32 (1.14-1.53), TCA/Other HR: 1.26 (1.01-1.58)], and diabetes (any type) [SSRI HR: 1.28 (1.10-1.49), TCA/Other: 1.52 (1.19-1.94)]. All commonly prescribed antidepressants except citalopram were associated with increased mortality compared with no antidepressants. However, prescription ≥1 year of ≥40mg citalopram was associated with increased mortality and falls/fractures and ≥1 year 100mg sertraline with increased falls/fractures.CONCLUSIONSIn overweight/obese people with depression, antidepressants may be overall and differentially associated with increased risks of some adverse outcomes. Further research is required to exclude indication bias and residual confounding.
  • Mediterranean diet and the hallmarks of ageing

    Stephan, Blossom C. M. (2021)
    Ageing is a multifactorial process associated with reduced function and increased risk of morbidity and mortality. Recently, nine cellular and molecular hallmarks of ageing have been identified, which characterise the ageing process, and collectively, may be key determinants of the ageing trajectory. These include genomic instability, telomere attrition, epigenetic alterations, loss of proteostasis, deregulated nutrient sensing, mitochondrial dysfunction, cellular senescence, stem cell exhaustion and altered intercellular communication. Healthier dietary patterns reduce the risk of age-related diseases and increase longevity and may influence positively one or more of these hallmarks. The Mediterranean dietary pattern (MedDiet) is a plant-based eating pattern that was typical of countries such as Greece, Spain, and Italy pre-globalisation of the food system and which is associated with better health during ageing. Here we review the potential effects of a MedDiet on each of the nine hallmarks of ageing, and provide evidence that the MedDiet as a whole, or individual elements of this dietary pattern, may influence each hallmark positively-effects which may contribute to the beneficial effects of this dietary pattern on age-related disease risk and longevity. We also highlight potential avenues for future research.
  • Feasibility and acceptability of a multi-domain intervention to increase Mediterranean diet adherence and physical activity in older UK adults at risk of dementia: protocol for the MedEx-UK randomised controlled trial

    Stephan, Blossom C. M. (2021)
    INTRODUCTION: Dementia prevalence continues to increase, and effective interventions are needed to prevent, delay or slow its progression. Higher adherence to the Mediterranean diet (MedDiet) and increased physical activity (PA) have been proposed as strategies to facilitate healthy brain ageing and reduce dementia risk. However, to date, there have been no dementia prevention trials in the UK focussed on combined dietary and PA interventions. This study aims to: (1) assess feasibility and acceptability of a theory-underpinned digital and group-based intervention for dementia risk reduction in an 'at risk' UK cohort; (2) evaluate behaviour change responses to the intervention; and, (3) provide information on cognitive, neurological, vascular and physiological outcomes to inform the design of a follow-on, full-scale efficacy trial. METHODS: One hundred and eight participants aged 55 to 74 years with a QRISK2 score of ≥10% will be recruited to take part in this 24-week multi-site study. Participants will be randomised into three parallel arms: (1) Control; (2) MedDiet; and, (3) MedDiet+PA. The study will evaluate a personalised website, group session and food delivery intervention to increase MedDiet adherence and PA in older adults at risk of dementia. Diet and PA will be monitored prior to, during and following the intervention. Feasibility, acceptability and hypothesised mediators will be assessed in addition to measures of cognitive function, brain structure/perfusion (MRI), vascular function and metabolic markers (blood, urine and faecal) prior to, and following, the intervention. DISCUSSION: This trial will provide insights into the feasibility, acceptability and mechanism of effect of a multi-domain intervention focussed on the MedDiet alone and PA for dementia risk reduction in an 'at risk' UK cohort. ETHICS AND DISSEMINATION: The study has received NHS REC and HRA approval (18/NI/0191). Findings will be disseminated via conference presentations, public lectures, and peer-reviewed publications. TRIAL REGISTRATION DETAILS: ClinicalTrials.gov NCT03673722.
  • What are the risk factors for malnutrition in older-aged institutionalized adults?

    Stephan, Blossom C. M. (2020)
    Malnutrition is common in older adults and is associated with functional impairment, reduced quality of life, and increased morbidity and mortality. The aim of this study was to explore the association between health (including depression), physical functioning, disability and cognitive decline, and risk of malnutrition. Participants were recruited from nursing homes in Italy and completed a detailed multidimensional geriatric evaluation. All the data analyses were completed using Stata Version 15.1. The study included 246 participants with an age range of 50 to 102 (80.4 ± 10.5). The sample was characterised by a high degree of cognitive and functional impairment, disability, and poor health and nutritional status (according to Mini Nutritional Assessment (MNA), 38.2% were at risk for malnutrition and 19.5% were malnourished). Using a stepwise linear regression model, age (B = −0.043, SE = 0.016, p = 0.010), depression (B = −0.133, SE = 0.052, p = 0.011), disability (B = 0.517, SE = 0.068, p < 0.001), and physical performance (B = −0.191, SE = 0.095, p = 0.045) remained significantly associated with the malnutrition risk in the final model (adjusted R-squared = 0.298). The logistic regression model incorporating age, depression, disability, and physical performance was found to have high discriminative accuracy (AUC = 0.747; 95%CI: 0.686 to 0.808) for predicting the risk of malnutrition. The results of the study confirm the need to assess nutritional status and to investigate the presence of risk factors associated with malnutrition in order to achieve effective prevention and plan a better intervention strategy. © 2020 by the authors.

  • Nutrition, growth, and other factors associated with early cognitive and motor development in Sub-Saharan Africa: a scoping review

    French, Blandine (2020)
    BACKGROUND: Food insecurity, poverty and exposure to infectious disease are well-established drivers of malnutrition in children in Sub-Saharan Africa. Early development of cognitive and motor skills - the foundations for learning - may also be compromised by the same or additional factors that restrict physical growth. However, little is known about factors associated with early child development in this region, which limits the scope to intervene effectively. To address this knowledge gap, we compared studies that have examined factors associated with early cognitive and/or motor development within this population. METHODS: Predetermined criteria were used to examine four publication databases (PsycInfo, Embase, Web of Science and Medline) and identify studies considering the determinants of cognitive and motor development in children aged 0-8 years in Sub-Saharan Africa. RESULTS: In total, 51 quantitative studies met the inclusion criteria, reporting on 30% of countries across the region. Within these papers, factors associated with early child development were grouped into five themes: Nutrition, Growth and Anthropometry, Maternal Health, Malaria and HIV, and Household. Food security and dietary diversity were associated with positive developmental outcomes, whereas exposure to HIV, malaria, poor maternal mental health, poor sanitation, maternal alcohol abuse and stunting were indicators of poor cognitive and motor development. DISCUSSION: In this synthesis of research findings obtained across Sub-Saharan Africa, factors that restrict physical growth are also shown to hinder the development of early cognitive and motor skills, although additional factors also influence early developmental outcomes. The study also reviews the methodological limitations of conducting research using Western methods in sub-Saharan Africa.
  • Incidence of depression and first-line antidepressant therapy in people with obesity and depression in primary care

    Morriss, Richard K. (2020)
    Objective: The aim of this study was to describe the age- and gender-specific incidence of depression, the dose-response relationship between BMI and risk of depression (Cox proportional hazards), and antidepressant drug prescribing in adults with overweight or obesity. Methods: A retrospective electronic health record study using the Clinical Practice Research Datalink was conducted to identify adults with overweight and obesity (≥ 18 years) with incident depression (no prior depression diagnosis in their records), followed up from 2000 to 2019. Results: Among 519,513 adults, incidence of depression was 9.2 per 1,000 person-years and was higher in women and in 40- to 59-year-old men who had severe obesity. Compared with having overweight, the hazard of depression increased with each BMI category as follows: 1.13 (30-34 kg/m2; 95% CI: 1.10-1.16), 1.34 (35-39 kg/m2; 1.29-1.40), 1.51 (40-44 kg/m2; 1.41-1.61), and 1.67 (45-49 kg/m2; 1.48-1.87), attenuating at BMI 50+ kg/m2 (1.54; 2.91-1.84). Antidepressants were prescribed as first-line therapy in two-thirds (66.3%) of cases. Prescriptions for fluoxetine reduced over time (20.4% [2000]; 8.8% [2018]), and prescriptions for sertraline increased (4.3% [2000]; 38.9% [2018]). Conclusions: We recommend guidance on antidepressant drug prescribing and specific services for people with obesity and depression that address both symptoms and behaviors. © 2020 The Obesity Society
  • Proactive Assessment of Obesity Risk during Infancy (ProAsk): A qualitative study of parents' and professionals' perspectives on an mHealth intervention

    Glazebrook, Cris; Ablewhite, Joanne (2019)
    Background: Prevention of childhood obesity is a public health priority. Interventions that establish healthy growth trajectories early in life promise lifelong benefits to health and wellbeing. Proactive Assessment of Obesity Risk during Infancy (ProAsk) is a novel mHealth intervention designed to enable health professionals to assess an infant's risk of future overweight and motivate parental behaviour change to prevent childhood overweight and obesity. The aim of this study was to explore parents' and health professionals' experiences of the overweight risk communication and behaviour change aspects of this mHealth intervention. Methods: The study was conducted in four economically deprived localities in the UK. Parents (N = 66) were recruited to the ProAsk feasibility study when their infant was 6-8 weeks old. Twenty two health visitors (HVs) used a hand-held tablet device to deliver ProAsk to parents when their infants were 3 months old. Parents (N = 12) and HVs (N = 15) were interviewed when infants in the study were 6 months old. Interview data were transcribed and analysed thematically using an inductive, interpretative approach. Results: Four key themes were identified across both parent and health visitor data: Engaging and empowering with digital technology; Unfamiliar technology presents challenges and opportunity; Trust in the risk score; Resistance to targeting. Most participants found the interactivity and visual presentation of information on ProAsk engaging. Health visitors who were unfamiliar with mobile technology drew support from parents who were more confident using tablet devices. There was evidence of resistance to targeting infants at greatest risk of future overweight and obesity, and both parents and health visitors drew on a number of reasons why a higher than average overweight risk score might not apply to a particular infant. Conclusions: An mHealth intervention actively engaged parents, enabling them to take ownership of the process of seeking strategies to reduce infant risk of overweight. However, cognitive and motivational biases that prevent effective overweight risk communication are barriers to targeting an intervention at those infants most at risk.

  • "I am gaining weight-get me out of here." What happens to body mass index (BMI) following admission to a medium secure unit?

    Bloye, Darran; Bowlie, S. (2011)
    Introduction: A diagnosis of mental illness has been associated with weight gain, particularly among patients suffering from schizophrenia. Aims & objectives: This study aims to establish trends in weight gain among inpatients and the effects of several public health interventions between 2006 and 2009. Methods: A body mass index (BMI) was calculated on admission and one of the authors has routinely measured the BMI of all inpatients on an annual basis since 2005 as part of a regular audit cycle. Results: Admission BMIs are comparable to the male general population2. The vast majority of patients are prescribed antipsychotic medication, approximately 50% receiving clozapine or olanzapine at any given time. There is a wide range of weight change from admission to discharge (-8.5kg to +60kg) but the average BMI of each sample exceeds the general population such that a majority of patients in each sample are clinically obese (BMI &gt;=30).In response to the audit findings the unit promoted public health and individual care plans (2006-09) aimed at addressing the high rates of obesity. Despite these initiatives there was a substantial rise in mean BMI between July 2007 and February 2008. Conclusions: Admission to a medium secure unit results in substantial weight gain for the majority of patients. The causes of weight gain in a relatively closed institution are probably multi-factorial in origin.
  • Digital technology to facilitate Proactive Assessment of Obesity Risk during Infancy (ProAsk): a feasibility study

    Ablewhite, Joanne; Glazebrook, Cris (2017)
    OBJECTIVE: To assess the feasibility and acceptability of using digital technology for Proactive Assessment of Obesity Risk during Infancy (ProAsk) with the UK health visitors (HVs) and parents. DESIGN: Multicentre, pre- and post-intervention feasibility study with process evaluation. SETTING: Rural and urban deprived settings, UK community care. PARTICIPANTS: 66 parents of infants and 22 HVs. INTERVENTION: ProAsk was delivered on a tablet device. It comprises a validated risk prediction tool to quantify overweight risk status and a therapeutic wheel detailing motivational strategies for preventive parental behaviour. Parents were encouraged to agree goals for behaviour change with HVs who received motivational interviewing training. OUTCOME MEASURES: We assessed recruitment, response and attrition rates. Demographic details were collected, and overweight risk status. The proposed primary outcome measure was weight-for-age z-score. The proposed secondary outcomes were parenting self-efficacy, maternal feeding style, infant diet and exposure to physical activity/sedentary behaviour. Qualitative interviews ascertained the acceptability of study processes and intervention fidelity. RESULTS: HVs screened 324/589 infants for inclusion in the study and 66/226 (29%) eligible infants were recruited. Assessment of overweight risk was completed on 53 infants and 40% of these were identified as above population risk. Weight-for-age z-score (SD) between the infants at population risk and those above population risk differed significantly at baseline (-0.67 SD vs 0.32 SD). HVs were able to collect data and calculate overweight risk for the infants. Protocol adherence and intervention fidelity was a challenge. HVs and parents found the information provided in the therapeutic wheel appropriate and acceptable. CONCLUSION: Study recruitment and protocol adherence were problematic. ProAsk was acceptable to most parents and HVs, but intervention fidelity was low. There was limited evidence to support the feasibility of implementing ProAsk without significant additional resources. A future study could evaluate ProAsk as a HV-supported, parent-led intervention. TRIAL REGISTRATION NUMBER: NCT02314494 (Feasibility Study Results).
  • Gluten- and casein-free diets for autistic spectrum disorder

    Ferriter, Michael (2008)
    Background: It has been suggested that peptides from gluten and casein may have a role in the origins of autism and that the physiology and psychology of autism might be explained by excessive opioid activity linked to these peptides. Research has reported abnormal levels of peptides in the urine and cerebrospinal fluid of people with autism. Objectives: To determine the efficacy of gluten and/or casein free diets as an intervention to improve behaviour, cognitive and social functioning in individuals with autism. Search strategy: The following electronic databases were searched: CENTRAL(The Cochrane Library Issue 2, 2007), MEDLINE (1966 to April 2007), PsycINFO (1971 to April 2007), EMBASE (1974 to April 2007), CINAHL (1982 to April 2007), ERIC (1965 to 2007), LILACS (1982 to April 2007), and the National Research register 2007 (Issue1). Review bibliographies were also examined to identify potential trials. Selection criteria: All randomised controlled trials (RCT) involving programmes which eliminated gluten, casein or both gluten and casein from the diets of individuals diagnosed with an autistic spectrum disorder. Data collection and analysis: Abstracts of studies identified in searches of electronic databases were assessed to determine inclusion by two independent authors The included trials did not share common outcome measures and therefore no meta-analysis was possible. Data are presented in narrative form. Main results: Two small RCTs were identified (n = 35). No meta-analysis was possible. There were only three significant treatment effects in favour of the diet intervention: overall autistic traits, mean difference (MD) = -5.60 (95% CI -9.02 to -2.18), z = 3.21, p=0.001 (Knivsberg 2002) ; social isolation, MD = -3.20 (95% CI -5.20 to 1.20), z = 3.14, p = 0.002) and overall ability to communicate and interact, MD = 1.70 (95% CI 0.50 to 2.90), z = 2.77, p = 0.006) (Knivsberg 2003). In addition three outcomes showed no significant difference between the treatment and control group and we were unable to calculate mean differences for ten outcomes because the data were skewed. No outcomes were reported for disbenefits including harms. Authors' conclusions: Research has shown of high rates of use of complementary and alternative therapies (CAM) for children with autism including gluten and/or casein exclusion diets. Current evidence for efficacy of these diets is poor. Large scale, good quality randomised controlled trials are needed. Copyright © 2008 The Cochrane Collaboration.

    OBJECTIVE: The aim of this study was to develop and validate a risk score algorithm for childhood overweight based on a prediction model in infants.
  • Focus on mental health promotion, obesity and alcohol

    Baldwin, Victoria (2014)
    Chapter nine in 'The Essential Guide to Public Health and Health Promotion' focuses on mental health promotion, obesity and alcohol. The eight sections on mental health promotion supply background information, promotion and prevention, mental health interventions, models of mental health promotion and key principles. The five sub-sections here consider the service user/target group, sustainability, service user co-production, partnership working and evidence and outcomes. There is a concluding summary and a case study. Obesity follows in five sections, beginning with obesity as a public health issue. There are key stages when people are likely to put on weight, and a list of the positive outcomes of reducing weight. The evidence base for weight loss in section two includes an effective range of lifestyle interventions and a list of NICE guidance documents related to obesity, diet and physical activity. Surgical methods of weight loss (bariatric surgery) are discussed. It is only appropriate when all other non-surgical approaches have failed. The six key strategies for maintaining weight loss follow in section four, and current interventions which lists a four-tiered prevention and management of excess weight model. There is a concluding summary. Alcohol consumption follows in two sections. Alcohol as a public health issue notes that excess alcohol consumption costs the NHS an estimated 3.5 billion annually and the issues surrounding reduced consumption and complete abstinence are reviewed. A case study of the Last Orders alcohol prevention service in Nottingham follows with a general discussion of outreach services. Cites numerous references.
  • Nutrition promotion: theories and methods, systems and settings

    Knight, Claire (2010)
    Reviews the book, Nutrition promotion. Theories and Methods, Systems and Setting by Tony Worsley (2008). The author has vast experience in the evaluation of public health nutrition programs, and in the promotion and maintenance of behavior change. This comprehensive text is ideal for anyone new to nutritional promotion or an additional resource for those interested in this area of nutrition. There is a logical sequence to the chapters; however, each chapter could be read in isolation and the author refers to relevant theory and models already cited in previous chapters. Effective interventions and critical appraisals of credible global examples of nutrition promotion are always given to back up the theory, making the information more accessible to clinical practice. This book highlights clearly the importance of not complicating the basics. This book is a good resource to refer to and will give a clear understanding of the role of nutrition promoter and provide a comprehensive overview of nutrition in that area, setting or population.
