Aim In a high proportion of people with recently diagnosed Type 2 diabetes, a short (2-3-month) low-calorie diet is able to restore normal glucose and insulin metabolism. The aim of this study was to determine the feasibility of this approach in Barbados. Methods Twenty-five individuals with Type 2 diabetes diagnosed within past 6 years, not on insulin, BMI ≥ 27 kg/m 2 were recruited. Hypoglycaemic medication was stopped on commencement of the 8-week liquid (760 calorie) diet. Insulin response was assessed in meal tests at baseline, 8 weeks and 8 months. Semi-structured interviews, analysed thematically, explored participants' experiences. 'Responders' were those with fasting plasma glucose (FPG) < 7 mmol/l at 8 weeks. Results Ten men and 15 women (mean age 48, range 26-68 years) participated. Mean (SD) BMI was 34.2 kg/m 2 (6.0); FPG 9.2 mmol/l (2.2). Mean weight loss at 8 weeks and 8 months was 10.1 kg [95% confidence interval (CI) 8.1, 12.0] and 8.2 kg (95% CI 5.8, 10.6); FPG was lower by 2.2 mmol/l (95% CI 1.2, 3.2) and 1.7 mmol/l (95% CI 0.8, 2.7) respectively. Nine of 11 (82%) of those who lost ≥ 10 kg were 'responders' compared with 6 of 14 (43%) who lost < 10 kg (P = 0.048). The 30-min insulin increment was higher in responders at baseline and follow-up (P ≤ 0.01). A food culture based on starchy foods and pressures to eat large amounts at social events were among the challenges identified by participants. Conclusions The feasibility of this approach to weight loss and diabetes remission in a predominantly black population in Barbados was demonstrated.

Background: Remission of type 2 diabetes through weight loss is possible in a high proportion of persons with a recent diagnosis, but a major challenge is achieving sufficient weight loss. Objectives: In the first study of this type in the Caribbean, we investigated factors associated with successful weight loss in adults in a diabetes remission intervention. We hypothesized that differences in social support may have influenced differences in weight loss achieved by participants in the Barbados Diabetes Reversal Study (BDRS). Methods: A comparative case study was conducted. Quantitative data for the primary outcome measure of weight reduction (the participants baseline and 8-month weights) were assessed to identify the 6 participants with the highest and 6 participants with the lowest weight loss. The 8-week (low-calorie diet phase) and 8-month (weight maintenance phase) interview transcripts for each participant were then analyzed via qualitative thematic analysis to explore factors related to social support. Results: Informal and formal support were identified for both categories of participants. Cases were similar with respect to their sources of support however dissimilarities were found in (1) the depth of support received; (2) access to supportive environments and (3) diversity of social supportive networks. Participants in the top weight loss group reported consistency in the levels of support received over the low-calorie diet and weight maintenance phases of the study while the converse was true for those of the bottom weight loss group. Conclusion: Study findings suggest that individuals aiming at type 2 diabetes remission benefit from strong social support networks. These networks provide tangible assistance and facilitate the sharing and discussion of strategies for weight reduction. Future studies should facilitate in-depth understanding of how formal and informal supportive networks can aid sustained dietary diabetes remission and long-term weight maintenance.

In response to the epidemic of non-communicable diseases (NCDs) in the Caribbean, the Heads of Government of the Caribbean Community (CARICOM) issued the 2007 Port-of-Spain Declaration, “Uniting to Stop the Epidemic of Chronic Non-communicable Diseases” and declared the second Saturday in September to be “Caribbean Wellness Day” (CWD). CWD is a call-to-action for engaging the population of the Member States in confronting NCDs and their risk factors. This report reviews the genesis, implementation, and institutionalization of CWD in CARICOM and beyond. The study used quantitative and qualitative methods, including 29 surveys, 7 in-depth interviews, and analysis of media content. Data was provided by NCD focal points at the Ministry of Health in 15 CARICOM countries, as well as by 7 non-governmental and 4 private organizations. Branding materials were well received and locally adapted; much of CWD media content originated from organization websites and were not community-based. Events typically focused on physical activity and health screenings and were attended by up to 3 000 participants. Though most were held in city centers, some CWD activities have involved rural and indigenous populations. CWD has become a catalyst for multisectoral engagement and health promotion activities. Inspired by CWD, PAHO initiated “Wellness Week in the Americas,” which includes CWD and promotes its tenets across the Region of the Americas. As CWD further develops, consideration should be given to reliable, adequate, and sustainable financing; to measuring and evaluating its impact on NCDs; and to widening its reach to include those outside of city centers.

Rapid weight loss using a very low-calorie diet (VLCD) for 2 to 3 months followed by weight maintenance has been shown to lead to the restoration of normal glucose and insulin metabolism in people recently diagnosed with type 2 diabetes. We explored the barriers and facilitators of adhering to a VLCD for remission in an Afro-Caribbean population. Twenty-five participants completed an eight-week VLCD followed by a six-month structured weight maintenance phase. Semi-structured interviews and focus groups were thematically analysed. Cravings for ‘usual foods’ consumed by friends and family, stigma of diabetes and resulting lack of disclosure and the participants’ busy schedules were noted as predominant challenges throughout the study. In turn, social support and the participants’ internal drive were considered as key facilitators for success. VLCD is a feasible approach for type 2 diabetes remission. Self-motivation and supportive environments are however crucial in meeting and maintaining the weight loss goals.
