Many middle‐income countries now have a high prevalence of diabetes and need to address the problem of providing care for people with diabetes within limited resources. This study evaluated standards of preventive care in primary settings in three Caribbean countries. We studied case records at 17 clinics in 15 government health centres and 17 private general practitioners' offices in Barbados, Trinidad and Tobago and Tortola (British Virgin Islands). A census of all attenders over a 4 to 7 week period identified 1661 attenders with diabetes mellitus, approximately two‐thirds were women with a median age over 60 years. Overall 676/1342 (50%) had ‘poor’ blood glucose control (≥8 mmol l−1 fasting or ≥10 mmol l−1 random). The proportion with BP ≥160/95 mmHg or receiving treatment for hypertension was 943/1661 (57%), of whom 781/943 (83%) were prescribed drug treatment. Among those treated for hypertension only 181/781 (23%) had blood pressures <140/90 mmHg. Surveillance for complications affecting the feet (11%) or eyes (2%) was not performed systematically in any setting. Only 533 (32%) had recorded dietary advice and 79 (5%) had recorded exercise advice in the last 12 months. To begin to address some of these problems at a regional level, we incorporated results from this survey into a series of workshops held in collaboration with health ministries in 10 Caribbean countries, with participants from 13 countries. At these workshops health care workers participated in the process of developing guidelines for diabetes management in primary care. The guidelines have subsequently been widely disseminated through health ministries and non‐governmental organizations in the region. Further research is needed to evaluate the effectiveness of this approach, the constraints on diabetes care, and the most cost‐effective means of addressing them.
Objectives: To describe (1) the prevalence of overweight and obesity and their association with physical activity; (2) the effect of different cut-off points for body mass index (BMI) on weight status categorisation; and (3) associations of weight status with perceptions of body size, health and diet quality. Design: A cross-sectional study. Setting: Secondary schools in Barbados. Subjects: A cohort of 400 schoolchildren, 11-16 years old, selected to study physical education practices. Results: Prevalence of overweight (15% boys; 17% girls) and obesity (7% boys; 12% girls) was high. Maternal obesity, as defined by the International Obesity Task Force (IOTF) BMI cut-off points, predicted weight status such that reporting an obese mother increased the odds of being overweight by 5.25 (95% confidence interval: 2.44, 11.31). Physical activity was inversely associated with weight status; however levels were low. Recreational physical activity was not associated with weight status in either category. Overweight subjects tended to misclassify themselves as normal weight and those who misclassified perceived themselves to be of similar health status to normal-weight subjects. The National Center for Health Statistics and IOTF BMI cut-off points produced different estimates of overweight and obesity. Conclusions: Our findings suggest that inadequate physical activity and ignorance related to food and appropriate body size are promoting high levels of adiposity with a strong contribution from maternal obesity, which may be explained by perinatal and other intergenerational effects acting on both sexes. Prevalence studies and local proxy tools for adiposity assessment are needed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
