Meta Analyses

Epidemiological research into insulin resistance has focused on excess body weight, type 2 diabetes mellitus (DM), physical activity, and coffee consumption. These common modifiable factors have also been suggested to play a role in the process of carcinogenesis via associations with insulin resistance. Findings of systematic literature reviews and meta-analyses have generally supported an association between excess body weight and DM with an increased risk of colon cancer in males, and of liver, pancreatic, and endometrial cancers. Inverse relationships between these cancers and physical activity and coffee consumption have been shown, both of which are known to reduce the risk of DM. Interventions directed at or involving these variables should contribute to decreasing the risk of insulin resistance-associated cancer.

Given current lack of therapies for dementia, there is substantial interest in identifying potentially modifiable risk factors. Clarifying the potential of these factors to mitigate risk as well as determining the mechanisms that link these factors to dementia is expected to lead to new approaches for both preventing and treating neurodegenerative diseases such as Alzheimer disease. Modifiable factors include cardiovascular risks as well as related lifestyle-centric factors such as diet and physical activity (reviewed in this issue). Given reports that type 2 diabetes and associated features increase the risk for developing dementia, there has been tremendous interest in exploring whether use of antidiabetic medications may impact the risk of dementia, as well as whether antidiabetic medications could be used to prevent or treat dementia, particularly Alzheimer disease. This review will briefly cover the known links between diabetes and risk for dementia, the state of evidence linking antidiabetic treatments with either protection against dementia or possibly increased risk for cognitive dysfunction, and provide a brief overview of what has been learned from clinical trials testing antidiabetic treatments in Alzheimer disease.

Risk Of Progression

Background: People with prediabetes have an increased risk of developing type 2 diabetes (T2D). Few studies have evaluated the influence of lifestyle factors on the risk of progression to diabetes and reversion to normoglycemia. The aim of this study was to determine the incidence of T2D in a large cohort of workers with prediabetes, and to evaluate the influence of sociodemographic, clinical, metabolic, and lifestyle factors that affect the persistence of prediabetes and the progression to T2D. Methods: A cohort study of 27,844 adult workers (aged 20 to 65 years) from Spain who had prediabetes based on an occupational medical examination from 2012 to 2013. Prediabetes was defined as fasting plasma glucose (FPG) between 100 and 125 mg/dL. At the baseline evaluation, sociodemographic, anthropometric, metabolic, and lifestyle data were collected. At the 5-year follow-up, incident T2D was defined as an FPG of at least 126 mg/dL or initiation of an antidiabetic medication. Results: Among 235,995 initially screened workers, the prevalence of T2D was 14.19% (95% confidence interval (CI) 14.05 to 14.33) and the prevalence of prediabetes was 11.85% (95% CI 11.71 to 11.99). Follow-up data were available for 23,293 individuals with prediabetes. Among them, 36.08% (95% CI 35.46 to 36.70) returned to normoglycemia, 40.92% (95% CI 40.29 to 41.55) had persistent prediabetes, and 23.00% (95% CI 22.46 to 23.54) progressed to T2D. The risk for persistence of prediabetes and for progression to T2D increased with age, body mass index (BMI), triglyceride level, and less than 150 min/week of physical activity. An HbA1c level of 6% or greater was the strongest individual predictor of progression to T2D. Conclusions: Physical activity, diet, smoking, and BMI are modifiable factors that are associated with the persistence of prediabetes and the progression to T2D. The workplace is a feasible setting for the early detection of prediabetes and the promotion of lifestyles that can prevent progression to T2D.

Background: In observational studies, coffee consumption has been consistently associated with a lower risk of type 2 diabetes mellitus. Trials examining the effect of coffee consumption on glucose metabolism have been limited by the use of surrogate insulin sensitivity indices, small sample sizes, lack of blinding, and short follow-up duration. We aimed to overcome these limitations in a randomized placebo-controlled trial examining the effects of coffee consumption on insulin sensitivity. Methodology: We conducted a 24-week randomized placebo-controlled trial in 126 overweight, insulin-resistant (HOMA-IR ≥ 1.30), Chinese, Malay and Asian-Indian males and females aged 35-69 years. Participants were randomly assigned to receive 4 cups of instant regular coffee (n=62) or 4 cups of a coffee-like placebo beverage (n=64) per day. The primary outcome was bodyweight-standardized M-value (M bw ) assessed with a hyperinsulinemic euglycemic clamp. Secondary outcomes included other clamp-based insulin sensitivity measures, biological mediators of insulin sensitivity, and measures of fasting glucose metabolism, body weight and composition. Results: Coffee consumption did not significantly change insulin sensitivity as compared with placebo [% mean difference in M bw : 0.3% (95% CI: -12.0% to 14.2%), P =0.97]. Furthermore, no significant differences in fasting plasma glucose [3.0% (-1.1% to 7.3%), P =0.16] or biological mediators of insulin resistance, such as plasma adiponectin [1.5% (-3.4% to 6.6%), P =0.55], were observed between coffee and placebo groups after 24 weeks of intervention. Coffee consumption led to a loss of body weight as compared with placebo [-1.2% (-2.3% to -0.1%), P =0.03] resulting from a decrease in fat mass [-3.7% (-7.1% to -0.2%), P =0.04] . Conclusions: Consuming 4 cups per day of caffeinated coffee for 24 weeks had no significant effect on insulin sensitivity or biological mediators of insulin resistance. Coffee consumption led to a modest decrease in body fat as compared with coffee abstinence. Trial Registration: ClinicalTrials.gov identifier: NCT01738399. Registered on 28 November 2012.

Healthy Body

The epidemic of both obesity and type 2 diabetes is due to environmental factors, but the individuals developing the conditions possess a strong genetic predisposition. Observational surveys and intervention studies have shown that excess body fatness is the major environmental cause of type 2 diabetes, and that even a minor weight loss can prevent its development in high-risk subjects. Maintenance of a healthy body weight in susceptible individuals requires 45–60 minutes physical activity daily, a fat-reduced diet with plenty of fruit, vegetables, whole grain, and lean meat and dairy products, and moderate consumption of calorie containing beverages. The use of table values to predict the glycemic index of meals is of little – if any – value, and the role of a low-glycemic index diet for body weight control is controversial. The replacement of starchy carbohydrates with protein from lean meat and lean dairy products enhances satiety, and facilitate weight control. It is possible that dairy calcium also promotes weight loss, although the mechanism of action remains unclear. A weight loss of 5–10% can be induced in almost all obese patients providing treatment is offered by a professional team consisting of a physician and dieticians or nurses trained to focus on weight loss and maintenance. Whereas increasing daily physical activity and regular exercise does not significantly effect the rate of weight loss in the induction phase, it plays an important role in the weight maintenance phase due to an impact on daily energy expenditure and also to a direct enhancement of insulin sensitivity.

Aging Women

The metabolic syndrome (MetS) comprises individual components including central obesity, insulin resistance, dyslipidaemia and hypertension and it is associated with an increased risk of cardiovascular disease (CVD) and type 2 diabetes mellitus (T2DM). The menopause per se increases the incidence of MetS in aging women. The effect(s) of menopause on individual components of MetS include: i) increasing central obesity with changes in the fat tissue distribution, ii) potential increase in insulin resistance, iii) changes in serum lipid concentrations, which seem to be associated with increasing weight rather than menopause itself, and, iv) an association between menopause and hypertension, although available data are inconclusive. With regard to the consequences of MetS during menopause, there is no consistent data supporting a causal relationship between menopause and CVD. However, concomitant MetS during menopause appears to increase the risk of CVD. Furthermore, despite the data supporting the association between early menopause and increased risk of T2DM, the association between natural menopause itself and risk of T2DM is not evident. However, the presence and the severity of MetS appears to be associated with an increased risk of T2DM. Although the mechanism is not clear, surgical menopause is strongly linked with a higher incidence of MetS. Interestingly, women with polycystic ovary syndrome (PCOS) have an increased risk of MetS during their reproductive years; however, with menopausal transition, the risk of MetS becomes similar to that of non-PCOS women.

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.

Rates of type 2 diabetes mellitus continue to rise around the world, largely due to lifestyle factors such as poor diet, overeating, and lack of physical activity. Diet and eating is often the most challenging aspect of management and, when disordered, has been associated with increased risk for diabetes-related complications. Thus, there is a clear need for accessible and evidence-based interventions that address the complex lifestyle behaviors that influence diabetes management. The current study sought to assess the efficacy and acceptability of a pilot lifestyle intervention for women with type 2 diabetes and disordered eating. The intervention followed a cognitive behavioral therapy guided-self-help (CBTgsh) model and included several pillars of lifestyle medicine, including: diet, exercise, stress, and relationships. Ten women completed the 12-week intervention that provided social support, encouraged physical activity, and addressed eating behaviors and cognitions. Results indicate the lifestyle intervention was a feasible treatment for disordered eating behaviors among women with type 2 diabetes and was also associated with improved diabetes-related quality of life. The intervention was also acceptable to participants who reported satisfaction with the program. The current CBTgsh lifestyle intervention is a promising treatment option to reduce disordered eating and improve diabetes management.
