Obesity and weight misperception among adults in the Eastern Caribbean Health Outcomes Research Network (ECHORN) Cohort Study.

OBJECTIVE: Prior studies have suggested that weight misperception - underestimating one's actual weight - may be associated with reduced engagement in weight loss programmes, decreasing the success of initiatives to address obesity and obesity-related diseases. The purpose of this study was to examine the factors associated with weight misperception among Eastern Caribbean adults and its influence on engagement in weight control behaviour. METHODS: Data from the Eastern Caribbean Health Outcomes Research Network (ECHORN) Cohort Study were analysed (adults aged 40 and older, residing in the US Virgin Islands, Puerto Rico, Barbados and Trinidad). Weight misperception is defined as participants who under-assess their weight measured by body mass index (BMI). Multivariable logistic regression (n = 1,803 participants) was used to examine the association of weight misperception with BMI category, age, gender, education, history of non-communicable disease and attempt to lose weight. RESULTS: Weight misperception was common, with 54% of overweight (BMI 25-29 kg m-2), and 23% of obese class I (BMI 30-34.9 kg m-2) participants under-assessing their actual weight. Participants with higher levels of education, versus lower, had decreased odds of weight misperception (OR 0.5, p < 0.001). There were no significantly reduced odds of weight misperception in women versus men (OR 1.13, p = 0.367) or in individuals with history of diabetes versus none (OR 0.88, p = 0.418). Participants with weight misperception had 85% (p < 0.0001) lower odds of attempting weight loss than those with accurate weight perception. CONCLUSION: Weight misperception is common among adults with overweight and obesity in the Eastern Caribbean and is associated with lower likelihood of attempting weight loss. Obesity interventions, targeting similar populations, should incorporate approaches for addressing weight misperception to achieve measurable success.

Non-communicable chronic diseases and timely breast cancer screening among women of the Eastern Caribbean Health Outcomes Research Network (ECHORN) Cohort Study.

PURPOSE: The Caribbean population faces a growing burden of multiple non-communicable chronic diseases (NCDs). Breast cancer is the leading cause of cancer death for women in the Caribbean. Given the substantial burden of NCDs across the region, cancer prevention and control strategies may need to be specifically tailored for people with multiple co-morbidities. Preventive screening, such as timely mammography, is essential but may be either facilitated or hampered by chronic disease control. The main objective of this study is to examine the relationship between a chronic disease and timely breast cancer screening. METHODS: We conducted a cross-sectional data analysis using baseline data from the Eastern Caribbean Health Outcomes Research Network (ECHORN) Cohort Study-ECS. Our independent variables were presence of chronic diseases (hypertension or diabetes), defined as having been told by a clinical provider. Our dependent variable was timely screening mammography, as defined by receipt of mammography within the past 2 years. We examined bivariate and multivariate associations of covariates and timely screening mammography. RESULTS: In our sample (n = 841), 52% reported timely screening mammography. Among those with timely screening, 50.8% reported having hypertension, and 22.3% reported having diabetes. In our bivariate analyses, both diabetes and hypertension were associated with timely screening mammography. In partially adjusted models, we found that women with diabetes were significantly more likely to report timely screening mammography than women without diabetes. In our fully adjusted models, the association was no longer significant. Having a usual source of healthcare and a woman's island of residence were significantly associated with timely screening mammography (p < 0.05). CONCLUSIONS: We found that half of eligible women received timely screening mammography. Diabetes and hypertension, though common, are not associated with timely screening mammography. Usual source of care remains an important factor to timely breast cancer screening.

International medical graduates in the USA: a qualitative study on perceptions of physician migration.

Objectives Physician migration from low-income to high-income nations is a global concern. Despite the centrality of understanding the perspectives of international medical graduates (IMGs) who have experienced migration to understanding the causes and consequences of this phenomenon, empirical literature is limited. The authors sought to characterise the experiences of IMGs from limited resource nations currently practicing primary care in the USA, with a focus on their perspectives on physician migration. Design The authors conducted a qualitative study utilising in-depth, in-person interviews and a standardised interview guide. The sample comprised a diverse, purposeful sample of IMGs (n=25) from limited resource nations (defined as having ≤2 physicians per 1000 population). Results Analyses revealed four recurrent and unifying themes reflecting the perspectives of IMGs in the USA on physician migration: (1) decisions to migrate were pragmatic decisions made in the context of individual circumstance; (2) the act of migration ultimately affected participants' ability to return home in multiple, unpredictable ways; (3) the ongoing process of acclimation was coupled with inherent conflicts surrounding the decision to remain in the USA; and (4) the effects of policies in both the home country and in the USA occurred at multiple levels. Conclusion The perspectives of IMGs who have migrated to the USA are an important addition to the ongoing discussion surrounding the global health workforce. Our findings highlight the effects of workforce policies which are often developed and discussed in abstraction, but have real, measurable impacts on the lives of individuals. Future efforts to address physician migration will need to acknowledge the immediate needs of the health workforce as well as the long-term needs of individuals within health systems.

Distribution of cholesterol in Caribbean marine algae.

Eleven species of Caribbean marine algae (red, green, and brown) were investigated for their cholesterol content. All of them were found to contain this sterol. Consistent with previously reported results, all five red algae contained large quantities of cholesterol. However, the two brown algae and three of the four green algae in our study also contained significant quantities of cholesterol.
