Dichotomising the risk of hyperglycaemia into diabetes and prediabetes may render a disservice to patient care.

Cardiovascular diseases (CVDs) are the leading cause of death worldwide, accounting for one-third of global mortality. Prediabetes increases the risk of CVDs as well as several other conditions, yet people with prediabetes may not seek intervention, thinking that they do not have diabetes, as the risk of progression may have not been emphasised by the healthcare professional. Accumulating evidence indicates that hyperglycaemia represents a continuum of CVD risk and dichotomising the risk into type 2 diabetes and prediabetes may deter early clinical intervention. It is proffered that the term 'prediabetes' is a misnomer that may disguise a serious condition, fostering complacency and undermining its prognostic significance.

Systematic review of the barriers and facilitators to dietary modification in people living with type 2 diabetes and pre-diabetes from South Asian ethnic populations.

AIMS: Lifestyle and dietary modification are effective in the prevention and management of Type 2 diabetes Mellitus (T2DM). However, South Asian (SA) populations living in Western countries have low adherence rates to healthcare advice and experience poor diabetes control and clinical outcomes compared with the general population. This systematic review aimed to summarise the barriers and facilitators of dietary modification within people from South Asian (SA) ethnicity with T2DM or pre-diabetes. METHODS: A systematic search of PubMed, Web of Science and Scopus generated 3739 articles, of which seven were included. Qualitative and quantitative data were inputted utilising COVIDENCE. Qualitative data were analysed by thematic analysis. RESULTS: Thematic analysis identified three facilitators: (1) cultural sensitivity, (2) health education and (3) support networks. Barriers include (1) healthcare inequity, (2) cultural insensitivity, (3) social pressures, (4) misconceptions and (5) time constraints. Good access to health care and motivation were the most common facilitators discussed. Misconceptions on T2DM management and cultural insensitivity contributed to the majority of barriers discussed. CONCLUSIONS: Culturally tailored interventions could improve adherence to diet modification in people with T2DM from SA ethnicity. Interventions involving the application of social media to challenge intergenerational stigmas and misinformation, distributing culturally appropriate resources and providing diets tailored to the SA palate could help.

Exercise and Lifestyle Education program for Brazilians living with prediabetes and diabetes: A pilot randomized trial.

AIMS: To test the Diabetes College Brazil Study feasibility, the acceptability of study interventions and their preliminary effectiveness, and describe the study protocol modifications due to the COVID-19 pandemic. METHODS: Single-center, double-blinded pilot randomized trial with two parallel groups, Exercise and Lifestyle Education (ExLE; 12-week exercise and educational interventions) and Exercise (Ex; 12-week exercise intervention only) involving patients with prediabetes or diabetes. Feasibility (eligibility, recruitment, retention, completeness of variables measures and participation rates), acceptability (satisfaction), and preliminary effectiveness of interventions (variables: functional capacity, physical activity (PA), exercise self-efficacy, diabetes knowledge, health literacy, adherence to Mediterranean food pattern, glycated hemoglobin (HbA1c), anthropometric measures, cardiac autonomic control, depression, and quality of life (QofL)). RESULTS: Eligibility, recruitment, retention, participation in exercise sessions, and education classes rates were 17%, 93%,82%, 76%, and 71%, respectively. Missing data in the post-intervention assessment (PA, HbA1c, cardiac autonomic control, anthropometric measures, depression, and QofL) were mainly related to research procedure modifications. The interventions were highly acceptable, and most variables improved farther in the ExLE, with moderate effect sizes for PA, diabetes knowledge, health literacy, cardiac autonomic control, and QofL. CONCLUSIONS: The Diabetes College Brazil Study is feasible, and the ExLE may benefit Brazilians living with prediabetes and diabetes.

Maintenance of Physical Activity Behavior by Individuals with Prediabetes and Diabetes during the COVID-19 Pandemic after Completing an Exercise Intervention in Brazil.

This cross-sectional study evaluated the perception of individuals with prediabetes/diabetes about their living conditions during the COVID-19 pandemic to identify the facilitators, barriers, and reasons to remain physically active at home and adhere to recommended exercise. It included individuals with prediabetes/diabetes who had completed an exercise intervention, which started on-site and moved to a remote home-based regime due to the COVID-19 pandemic and were advised to keep exercising at home. The outcomes were assessed by a bespoke questionnaire that was developed by the research team, the Brazilian Portuguese adapted version of the Exercise Adherence Rating scale, and the Motives for Physical Activity Measure-Revised scale. Of 15 participants (8 female, 58 ± 11 years), most reported positive perceptions about their living conditions and few difficulties maintaining some physical activity at home. However, only 53.8% of them adhered to the recommended exercise. Time flexibility, no need for commuting, and a sense of autonomy were the main facilitators of home exercise, while a lack of adequate space was the main barrier. The descending order of median scores that were obtained in each reason for physical activity was fitness, enjoyment, competence, social, and appearance. Individuals with prediabetes/diabetes maintained some physical activity during the pandemic, mainly motivated by health concerns.

Diabetes Prevention Education Program in a population with pre-diabetes in Nepal: a study protocol of a cluster randomised controlled trial (DiPEP).

INTRODUCTION: Evidence suggests that diabetes burden can be reduced by implementing early lifestyle intervention programmes in population with pre-diabetes in high-income countries. However, little is known in developing nations like Nepal. This study aims to assess effectiveness of community-based Diabetes Prevention Education Program (DiPEP) on haemoglobin A1c (HbA1c) level, proportion of pre-diabetes reverting to normoglycaemia, diet, physical activity, weight reduction, diabetes knowledge and health literacy after 6 months of follow-up. Furthermore, we will also conduct qualitative studies to explore experiences of participants of intervention sessions and perception of healthcare workers/volunteers about DiPEP. METHODS AND ANALYSES: This is a community-based two-arm, open-label, cluster randomised controlled trial. We will randomise 14 clusters into intervention arm and control arm. Estimated total sample size is 448. We will screen individuals without diabetes, aged 18-64 years, and permanent residents of study sites. HbA1c test will be only performed if both Indian Diabetes Risk Score and random blood sugar value are ≥60 and 140-250 mg/dL, respectively. At baseline, participants in intervention arm will receive DiPEP package (including intensive intervention classes, diabetes prevention brochure, exercise calendar and food record booklet), and participants in control arm will be provided only with diabetes prevention brochure. The change in outcome measures will be compared between intervention to control arm after 6 months of follow-up by linear mixed models. Also, we will conduct individual interviews among participants and healthcare workers as part of a qualitative study. We will use thematic analysis to analyse qualitative data. ETHICS AND DISSEMINATION: Regional Committee for Medical and Health Research Ethics, Norway; Nepal Health Research Council, Nepal and Institutional Review Committee, Kathmandu University School of Medical Sciences have approved the study. The DiPEP package can be implemented in other communities of Nepal if it is effective in preventing diabetes. TRIAL REGISTRATION NUMBER: NCT04074148, 2019/783.

The Mechanisms of the Development of Atherosclerosis in Prediabetes.

Lifestyle changes, such as overeating and underexercising, can increase the risk of prediabetes. Diabetes is one of the leading causes of atherosclerosis, and recently it became clear that the pathophysiology of atherosclerosis progresses even before the onset of diabetic symptoms. In addition to changes in platelets and leukocytes in the hyperglycemic state and damage to vascular endothelial cells, extracellular vesicles and microRNAs were found to be involved in the progression of prediabetes atherosclerosis. This review discusses the cellular and molecular mechanisms of these processes, with an intention to enable a comprehensive understanding of the pathophysiology of prediabetes and atherosclerosis.
