In the last 10 years nutritional research on diabetes has improved dramatically in terms of both number of studies produced and quality of methodologies employed. Therefore, it is now possible to attempt to provide the evidence on which nutritional recommendations for the prevention of type 2 diabetes could be based. We therefore performed a literature search and, among the papers published in indexed journals, we selected relevant epidemiological (mostly prospective) and controlled intervention studies. Lifestyle factors that have, so far, been consistently associated with increased risk of type 2 diabetes are overweight and physical inactivity. However, recent evidence from epidemiological studies has shown that the risk of type 2 diabetes is also associated with diet composition, particularly with: (1) low fibre intake; (2) a high trans fatty acid intake and a low unsaturated:saturated fat intake ratio; (3) absence of or excess alcohol consumption. All these factors are extremely common in Western populations and therefore the potential impact of any intervention on them is large: indeed, >90% of the general population has one or more of these risk factors. The ability to correct these behaviours in the population is estimated to reduce the incidence of diabetes by as much as 87%. Recent intervention studies have shown that type 2 diabetes can be prevented by lifestyle changes aimed at body-weight reduction, increased physical activity and multiple changes in the composition of the diet. Within this context, the average amount of weight loss needed is not large, about 5% initial weight, which is much less than the weight loss traditionally considered to be clinically significant for prevention of type 2 diabetes. In conclusion, new emphasis on prevention by multiple lifestyle modifications, including moderate changes in the composition of the habitual diet, might limit the dramatic increase in incidence of type 2 diabetes envisaged worldwide.

Abstract Context Weight loss is strongly recommended for overweight and obese adults with type 2 diabetes. Unintentional weight loss is associated with increased risk of all-cause mortality, but few studies have examined its association with cardiovascular outcomes in patients with diabetes. Objective To evaluate 2-year weight change and subsequent risk of cardiovascular events and mortality in established type 2 diabetes. Design and Setting The Action in Diabetes and Vascular Disease: Preterax and Diamicron-MR Controlled Evaluation was an international, multisite 2×2 factorial trial of intensive glucose control and blood pressure control. We examined 5 categories of 2-year weight change: >10% loss, 4% to 10% loss, stable (±<4%), 4% to 10% gain, and >10% gain. We used Cox regression with follow-up time starting at 2 years, adjusting for intervention arm, demographics, cardiovascular risk factors, and diabetes medication use from the 2-year visit. Results Among 10 081 participants with valid weight measurements, average age was 66 years. By the 2-year examination, 4.3% had >10% weight loss, 18.4% had 4% to 10% weight loss, and 5.3% had >10% weight gain. Over the following 3 years of the trial, >10% weight loss was strongly associated with major macrovascular events (hazard ratio [HR], 1.75; 95% confidence interval [CI], 1.26-2.44), cardiovascular mortality (HR, 2.76; 95% CI, 1.87-4.09), all-cause mortality (HR, 2.79; 95% CI, 2.10-3.71), but not major microvascular events (HR, 0.91; 95% CI, 0.61-1.36), compared with stable weight. There was no evidence of effect modification by baseline body mass index, age, or type of diabetes medication. Conclusions In the absence of substantial lifestyle changes, weight loss may be a warning sign of poor health meriting further workup in patients with type 2 diabetes.

BACKGROUND People from Black, Asian and Minority Ethnic (BAME) groups are known to have an increased risk of developing type 2 diabetes and face greater barriers to accessing healthcare resources compared to their “white British” counterparts. The main mediators of lifestyle behavioural change are gender, generation, geography, genes, God/religion, and gaps in knowledge and economic resources. Dietary and cultural practices of these individuals significantly vary according to gender, generation, geographical origin and religion. Recognition of these factors and implementing culturally sensitive interventions for type 2 diabetes prevention and management is essential in increasing knowledge of healthy eating, engagement in physical activity and improving health outcomes in BAME communities. Few health apps are tailored for BAME populations, and BAME communities are considered hard-to-reach. OBJECTIVE Our objective was to establish whether the Low Carb Program is a viable scalable solution that can be used as an effective tailored type 2 diabetes intervention for BAME communities. We hypothesized that by taking into account cultural sensitivities, providing the platform in native languages and personalising the platform in accordance with known barriers to health disparities including gender, generation, dietary preferences and religion, the app would engage BAME communities and improve type 2 diabetes related health outcomes. METHODS The study used a quasi-experimental research design comprised of an open-label, single-arm, pre-post intervention using a sample of convenience. All 705 adults with type 2 diabetes who had activated their referral to the Low Carb Program as a result of an NHS consultation between September 2018 and March 2019 were followed for a period of 12 months; mean age 54.61 (SD 16.69) years; 58.2% (410/705) women; 45.1% (318/705) white, 28.5% (201/705) Indian/Pakistani/Bangladeshi/Other Central Asian, 10.8% (76/705) Arab, 6.2% (44/705) Mixed/Multiple ethnic groups, 6% (43/705) black, 1.8% (13/705) other, (7/705) 1% Chinese/Japanese/Other East Asian. Mean starting glycated haemoglobin A1c (HbA1c) 7.99% (SD 2.05%); mean body weight 88.96kg (SD 23.25kg). RESULTS Of the 705 study participants, 513 (72.76%) had completed the Low Carb Program at 12 months. There were statistically significant reductions in body weight and HbA1c in white, Indian/Pakistani/Bangladeshi/Other Central Asian, Arabic and black participants with the most significant differences in the Indian/Pakistani/Bangladeshi/Other Central Asian population HbA1c -1.18% (SD 1.49%) and weight 8.03kg (SD 10.65kg). 82.9% of all participants (419/705) of all participants lost at least 5% of their body weight. CONCLUSIONS Offering the culturally tailored Low Carb Program that empowers members to make dietary and lifestyle changes to different BAME groups is an effective and engaging tool in the management of type 2 diabetes. Most importantly, BAME populations in particular people from Indian/Pakistani/Bangladeshi and Arabic groups who achieve better health outcomes than their white counterparts.

AbstractThis cohort study aimed to compare the incidence of type 2 diabetes in adults with depression-related weight gain, depression-related weight loss, depression with no weight change, and no depression. The study sample included 59,315 community-dwelling adults in Ontario, Canada. Depression-related weight change in the past 12 months was measured using the Composite International Diagnostic Interview—Short Form. Participants were followed for up to 20 years using administrative health data. Cox proportional hazards models compared the incidence of type 2 diabetes in adults with depression-related weight change and in adults with no depression. Adults with depression-related weight gain had an increased risk of type 2 diabetes compared to adults no depression (HR 1.70, 95% CI 1.32–2.20), adults with depression-related weight loss (HR 1.62, 95% CI 1.09–2.42), and adults with depression with no weight change (HR 1.39, 95% CI 1.03–1.86). Adults with depression with no weight change also had an increased risk of type 2 diabetes compared to those with no depression (HR 1.23, 95% CI 1.04–1.45). Associations were stronger among women and persisted after adjusting for attained overweight and obesity. Identifying symptoms of weight change in depression may aid in identifying adults at higher risk of type 2 diabetes and in developing tailored prevention strategies.

ObjectivesSeveral patients with type 2 diabetes mellitus (T2DM) have depressive disorders. Whether insulin treatment was associated with increased risk of depression remains controversial. We performed a meta-analysis to evaluate the association of insulin therapy and depression.DesignA meta-analysis.MethodsWe conducted a systematic search of PubMed, PsycINFO, Embase and the Cochrane Library from their inception to April 2016. Epidemiological studies comparing the prevalence of depression between insulin users and non-insulin users were included. A random-effects model was used for meta-analysis. The adjusted and crude data were analysed.ResultsTwenty-eight studies were included. Of these, 12 studies presented with adjusted ORs. Insulin therapy was significantly associated with increased risk of depression (OR=1.41, 95% CI 1.13 to 1.76, p=0.003). Twenty-four studies provided crude data. Insulin therapy was also associated with an odds for developing depression (OR=1.59, 95% CI 1.41 to 1.80, p<0.001). When comparing insulin therapy with oral antidiabetic drugs, significant association was observed for adjusted (OR=1.42, 95% CI 1.08 to 1.86, p=0.008) and crude (OR=1.61, 95% CI 1.35 to 1.93, p<0.001) data.ConclusionsOur meta-analysis confirmed that patients on insulin therapy were significantly associated with the risk of depressive symptoms.

Obesity Drugs

The prevalence of diabetes continues to rise, following the rising rates of obesity. Obesity is not only associated with an increased risk for developing type 2 diabetes but also an elevated probability of developing long-term complications associated with the disease. Weight gain is also an important concern as a potential side effect of therapies that improve glycemic control in diabetes, including insulin therapy. As a result, patients with type 2 diabetes are at risk for a vicious circle of increasing weight and increasing insulin resistance, thus requiring further intensification of glycemic treatment. It is therefore important to address the problem of obesity in patients with type 2 diabetes. In 2012, the US Food and Drug Administration (FDA) approved two new anti-obesity medications: lorcaserin and phentermine/topiramate extended-release. Both agents have demonstrated clinically meaningful weight reduction as well as significant improvements in glycemic control in obese patients with diabetes. Liraglutide has also shown weight loss and improvements in glycemic control in patients with diabetes. Anti-obesity drugs, in conjunction with lifestyle changes, may play a valuable role in the management of diabetes.

Obesity is a major risk factor for the development of type 2 diabetes;1–3moreover, the presence of obesity in type 2 diabetes is associated with an increased risk of vascular complications associated with the disorder.4,5The majority of patients are overweight or obese at diagnosis of type2diabetes. Recent clinical trials have demonstrated that progression to diabetes in obese patients with impaired glucose tolerance can be prevented through weight reduction and increased levels of physical activity.6,7For patients who have developed type 2 diabetes, intentional weight loss has many potential benefits including improved metabolic control and a reduced need for antidiabetic medications.8–10

<b>Objective </b>To estimate risk of fracture in men and women with recent diagnosis of type 2 diabetes compared to individuals without diabetes. <p><b>Research Design and Methods<strong> </strong></b>In this cohort study we used routinely-collected UK primary care data from The Health Improvement Network. In adults (>35 years) diagnosed with type 2 diabetes between 2004-2013 fractures sustained until 2019 were identified and compared to fractures sustained in individuals without diabetes. Multivariable models estimated time to first fracture following diagnosis of diabetes. Annual prevalence rates included at least one fracture in a given year. <strong></strong></p> <p><strong>Results </strong>Among 174,244 individuals with incident type 2 diabetes and 747,290 without diabetes, there was no increased risk of fracture among males with diabetes (adjusted hazards ratio (aHR) 0.97 (95%CI 0.94, 1.00)) and a small reduced risk among females (aHR 0.94, (95%CI 0.92, 0.96)). In those aged 85 years and over those in the diabetes cohort were at significantly lower risk of incident fracture (Males: aHR 0.85, 95%CI 0.71, 1.00; Females: aHR 0.85, 95%CI 0.78, 0.94). For those in the most deprived areas, aHRs were 0.90 (95%CI 0.83, 0.98) for males and 0.91 (95%CI 0.85, 0.97) for females. Annual fracture prevalence rates, by sex, were similar for those with and without type 2 diabetes.</p> <p><strong>Conclusion We found </strong>no evidence to suggest a higher risk of fracture following diagnosis of type 2 diabetes. After a diagnosis of type 2 diabetes individuals should be encouraged to make positive lifestyle changes, including undertaking weight-bearing physical activities that improve bone health.</p>

Thromboxane (TX)-dependent platelet activation and lipid peroxidation, as reflected in vivo by the urinary excretion of 11-dehydro-TXB2 and 8-iso-prostaglandin (PG)F2α, play a key role in atherothrombosis in obesity and type 2 diabetes mellitus (T2DM) since the earlier stages. Thirty-five metformin-treated obese subjects with prediabetes or newly-diagnosed T2DM were randomized to the glucagon-like peptide receptor agonist (GLP-RA) liraglutide (1.8 mg/day) or lifestyle counseling until achieving a comparable weight loss (−7% of initial body weight), to assess whether changes in subcutaneous (SAT) and visceral (VAT) adipose tissue distribution (MRI), insulin sensitivity (Matsuda Index) and beta-cell performance (multiple sampling OGTT beta-index), with either intervention, might affect TX-dependent platelet activation, lipid peroxidation and inflammation. At baseline, Ln-8-iso-PGF2α (Beta = 0.31, p = 0.0088), glycosylated hemoglobin (HbA1c) (Beta = 2.64, p = 0.0011) Ln-TNF-α (Beta = 0.58, p = 0.0075) and SAT (Beta = 0.14, p = 0.044) were significant independent predictors of 11-dehydro-TXB2. After achievement of the weight loss target, a comparable reduction in U-11-dehydro-TXB2 (between-group p = 0.679) and 8-iso-PGF-2α (p = 0.985) was observed in both arms in parallel with a comparable improvement in glycemic control, insulin sensitivity, SAT, high-sensitivity C-reactive protein (hs-CRP). In obese patients with initial impairment of glucose metabolism, the extent of platelet activation is related to systemic inflammation, isoprostane formation and degree of glycemic control and abdominal SAT. Successful weight loss, achieved with either lifestyle changes or an incretin-based therapy, is associated with a significant reduction in lipid peroxidation and platelet activation.
