OBJECTIVE: To understand preferences for features of weight loss programs among adults with or at risk of type 2 diabetes in the U.K. RESEARCH DESIGN AND METHODS: We conducted a discrete choice experiment with 3,960 U.K. adults living with overweight (n = 675 with type 2 diabetes). Preferences for seven characteristics of weight loss programs were analyzed. Simulations from choice models using the experimental data predicted uptake of available weight loss programs. Patient groups comprising those who have experience with weight loss programs, including from minority communities, informed the experimental design. RESULTS: Preferences did not differ between individuals with and without type 2 diabetes. Preferences were strongest for type of diet. Healthy eating was most preferred relative to total diet replacement (odds ratio [OR] 2.24; 95% CI 2.04–2.44). Individual interventions were more popular than group interventions (OR 1.40; 95% CI 1.34–1.47). Participants preferred programs offering weight loss of 10–15 kg (OR 1.37; 95% CI 1.28–1.47) to those offering loss of 2–4 kg. Online content was preferred over in-person contact (OR 1.24; 95% CI 1.18–1.30). There were few differences in preferences by gender or ethnicity, although weight loss was more important to women than to men, and individuals from ethnic minority populations identified more with programs where others shared their characteristics. Modeling suggested that tailoring programs to individual preferences could increase participation by ∼17 percentage points (68% in relative terms). CONCLUSIONS: Offering a range of weight loss programs targeting the preferred attributes of different patient groups could potentially encourage more people to participate in weight loss programs and support those living with overweight to reduce their weight.

Aim: To identify factors influencing dietary behaviour in shift workers with type 2 diabetes (T2D) working in UK healthcare settings. Methods: Semi‐structured qualitative interviews based on the theoretical domains framework (TDF) were conducted with a convenience sample (n = 15) of shift workers (32–59 years) diagnosed with T2D who worked night shifts as part of a mixed shift schedule. The TDF was applied to analyse transcripts using a combined deductive framework and inductive thematic analysis approach. Identified influences were mapped to the behaviour change technique taxonomy to identify potential strategies to change dietary behaviour in this context. Results: Key barriers to healthy dietary behaviours were access and cost of food available during night work (TDF domain: Environment Context and Resources). Factors identified as both enablers and barriers included: availability of staff facilities and time to take a break, (Environment Context and Resources), the physical impact of night work (Beliefs About Consequences), eating in response to stress or tiredness (Emotion), advance planning of meals/food and taking own food to work (Behavioural Regulation). Potential techniques to address these influences and improve dietary behaviour in this context include: meal planning templates, self‐monitoring and biofeedback, and increasing accessibility and availability of healthier food choices during night shifts. Conclusions: The dietary behaviour of shift workers with T2D is influenced by interacting individual, socio‐cultural and environmental factors. Intervention should focus on environmental restructuring and strategies that enable monitoring and meal planning. [ABSTRACT FROM AUTHOR]

Background: The present study aimed to understand the individual, social and environmental factors influencing dietary behaviour in shift workers with type 2 diabetes (T2D) working in UK healthcare settings. Methods: A cross‐sectional study was conducted using data collected from an anonymous online survey. Participant agreement was measured using five‐point Likert scale (strongly disagree to strongly agree) against 38 belief statements informed by the Theoretical Domains Framework (TDF) of behaviour change. Results: From the complete responses (n = 119), 65% worked shifts without nights, 27% worked mixed shift rota including nights and 8% worked only night shifts. The statements ranked with the highest agreements were in the TDF domains: Environment Context/Resources (ECR) – mainly identified as a barrier to healthy eating, Behaviour Regulation (BR) and intention (IN) – identified as enablers to healthy eating. For the belief statement 'the available options for purchasing food are too expensive' (ECR), 80% of night workers and 75% non‐night workers agreed/strongly agreed. Taking their own food to work to prevent making unhealthy food choices (BR) had agreement/strong agreement in 73% of non‐night and 70% night workers; 74% non‐night workers and 80% of night workers agreed/strongly agreed with the statement 'I would like to eat healthily at work' (IN). Mixed shift workers agreed that following dietary advice was easier when working a non‐night compared to a night shift (p = 0.002). Conclusions: Access and affordability of food were identified as important determinants of dietary behaviour during shifts. The findings support interventions targeting the food environment for shift workers with T2D. Key points: The present study investigated the individual, social and environmental factors influencing dietary behaviour in shift workers with type 2 diabetes (T2D) working in UK healthcare settings.The findings support previous findings from semi‐structured interviews, with the main domain influencing dietary behaviours being Environmental Context and Resources (i.e., physical and economic availability of food during shifts). The findings support interventions targeting the food environment across shift workers living with T2D. [ABSTRACT FROM AUTHOR]

Increasing 24‐h demand for products, services and health care is resulting in a substantial portion of the workforce engaging in shift work. Observational studies suggest an association between shift work exposure and increased incidence of cardiometabolic disease. Shift workers report less healthy diets compared to day workers. As diet is a modifiable behaviour, it is important to understand how it might mediate the relationship between shift work and health. We reviewed online dietary advice for shift workers by searching for existing guidelines for shift workers published by websites of credible sources, for example institutions or government agencies. Based on the 26 guidelines retrieved, the most common categories of advice were eating patterns (n = 25), general healthy eating and/or specific food groups (n = 22), control of caffeine intake (n = 23) and maintaining hydration/fluid intake (n = 17). Although the majority of publicly available advice for shift workers follows general healthy eating guidelines, there are inconsistencies in the recommendations around the frequency of eating and snacking. Few studies have investigated modification of diet quality in shift workers. With the goal of adding to the evidence base, the Shift‐eat study is a feasibility trial designed to test whether dietary intakes in line with UK healthy eating recommendations during night work improve markers of health (interstitial glucose and heart rate variability) in free‐living shift‐working employees. Shift work is unavoidable and necessary for many industries. With an increasing section of the population employed in jobs requiring shift work, consistent dietary guidance based on evidence from shift‐working populations is urgently needed to support maintenance of health and wellbeing in employees working outside standard daytime hours.

Background: NICE Guidelines for prevention of diabetes include identifying people at risk followed by cost-effective intervention if necessary. Based on assessment of risk via a questionnaire and/or blood test the intervention may comprise a brief discussion of risk factors and preventive advice or referral to intensive lifestyle intervention.Design and Setting: In this cross-sectional study 59 subjects recruited from local GP practices were invited by letter to attend a screening for a diabetes prevention study.Method: Following a telephone screening during which subjects were asked whether they had been informed if they were at high-risk of type 2 diabetes, eligible subjects completed a Risk Perception Survey for Developing Diabetes (RPS-DD), a validated diabetes risk score and underwent an oral glucose tolerance test (OGTT) at a medical screening.Results: As measured by the Diabetes UK Risk Score, 44.1% were at high risk, 42.4% moderate risk and 13.6% at increased risk. 42% of patients had been informed they were at high-risk by a health professional. Those who had been informed of their risk had significantly higher perceived risk scores (p<0.001), higher knowledge scores (p<0.001) and decreased optimism scores (p=0.004), but were not more aware that diet (p=0.42) and weight management (p=0.57) can play a role in preventing diabetes.Conclusions: People at high-risk of diabetes are not being informed of their risk status as recommended by NICE guidelines. There is scope for education for health professionals and the public. [ABSTRACT FROM AUTHOR]

Background: Fat infiltration of the liver, muscle and pancreas is associated with insulin resistance and risk of diabetes. Weight loss reduces ectopic fat deposition and risk of diabetes, but is difficult to sustain to due to compensatory increases in appetite. Fermentable carbohydrates have been shown to decrease appetite and food intake, and promote weight loss in overweight subjects. In animal studies, fermentable carbohydrate reduces ectopic fat independent of weight loss. We aimed to investigate the effect of the fermentable carbohydrate inulin on weight maintenance, appetite and ectopic fat in subjects with prediabetes. Methods: Forty-four subjects with prediabetes were randomized to 18 weeks' inulin or cellulose supplementation. During weeks 1-9 (weight loss phase) all subjects had four visits with a dietitian to guide them towards a 5 % weight loss. During weeks 10-18 (weight maintenance phase) subjects continued taking their assigned supplementation and were asked to maintain the weight they had lost but were offered no further support. All subjects attended study sessions at baseline, 9 and 18 weeks for measurement of weight; assessment of adipose tissue and ectopic fat content by magnetic resonance imaging and magnetic resonance spectroscopy; glucose, insulin and GLP-1 levels following a meal tolerance test; and appetite by meal test and visual analogue scales. ad libitum Results: Both groups lost approximately 5 % of their body weight by week nine (-5.3 ± 0.1 % vs -4.3 ± 0.4 %, p = 0.13, but the inulin group lost significantly more weight between 9 and 18 weeks (-2.3 ± 0.5 % vs -0.6 ± 0.4 %, p = 0.012). Subjects taking inulin had lower hepatic (p = 0.02) and soleus muscle (p < 0.05) fat content at 18 weeks compared to control even after controlling for weight loss and consumed less at the meal test (p = 0.027). Fasting glucose ad libitum significantly decreased at week nine only (p = 0.005), insulin concentrations did not change, and there was a significant increase in GLP-1 in the cellulose group at 9 and 18 weeks (p < 0.03, p < 0.00001). Conclusion: Inulin may have a two-pronged effect on the risk of diabetes by 1) promoting weight loss 2) reducing intrahepatocellular and intramyocellular lipid in people with prediabetes independent of weight loss.
