The changing faces of diabetes, hypertension and arthritis in a Caribbean population

Factors associated with the use of complementary and alternative therapies among patients with hypertension and type 2 diabetes mellitus in Western Jamaica: a cross-sectional study

Background

This study examined the prevalence and predictors of complementary and alternative medicine use among clinic patients with hypertension and/or type 2 diabetes mellitus in western Jamaica.

Methods

A cross-sectional study using an investigator-administered questionnaire was conducted from May to August 2017. Data on sociodemographic factors, complementary and alternative medicine use, and knowledge and perceptions of complementary and alternative medicine were collected from the patients. Multivariable logistic regression analysis was used to examine associations between patient characteristics and knowledge and perceptions of complementary and alternative medicine and complementary and alternative medicine use.

Results

A total of 362 patients were invited to participate and 345 (95.3%) completed the questionnaire; 311 (90.1%) had hypertension, 130 (37.7%) had type 2 diabetes mellitus and 96 (27.8%) had both diseases. Seventy-nine percent of the participants with hypertension and 65% with type 2 diabetes mellitus reported current use of complementary and alternative medicine. Self-reported knowledge of complementary and alternative medicine (none/poor vs average/good/excellent) was significantly associated with complementary and alternative medicine use for hypertension (AOR = 0.33, 95% CI = 0.13–0.87) and type 2 diabetes mellitus (AOR = 0.06, 95% CI = 0.01–0.37). Believing that complementary and alternative medicine is a natural method for treating hypertension was significantly associated with complementary and alternative medicine use among patients with hypertension (AOR = 3.9, 95% CI = 1.26–12.00), and belief that it is acceptable to use prescription medication and complementary and alternative medicine simultaneously was significantly associated with complementary and alternative medicine use among patients with type 2 diabetes mellitus (AOR =7.19, CI = 1.34–38.52).

Conclusions

Participants’ perceptions of their knowledge and beliefs regarding complementary and alternative medicine strongly influence their use of complementary and alternative medicine. These findings can be used in designing educational interventions to promote the proper use, and mitigate detrimental effects, of complementary and alternative medicine in this population.

Type 2 Diabetes Prevalence, Distribution and Risk Factors in St. Kitts and Nevis, West Indies

OBJECTIVES

This study in collaboration with the St. Kitts & Nevis Ministry of Health (MOH) investigated the prevalence of type 2 diabetes and its risk factors, the second leading cause of death in the country.

METHODS

Medical records of patients between the ages of 18 and 75 as of January 1, 2010 treated between January 1, 2010 and December 31, 2015 in the government-funded health centers (HCs) were eligible for inclusion (N = 2737). All HC visits (n = 4169) generated by a representative sample of patients (n = 761) were evaluated using Caribbean Public Health Association Public Health Association (CARPHA) guidelines for risk ranges.

RESULTS

The prevalence of type 2 diabetes is 23% and is concentrated in the 45-64 year-old cohort. Though women outnumber men 3:1 in the sample, gender-prevalence rates are similar (23% and 22% respectively). There is also evidence that comorbidities are prevalent among diabetics (76%) and many nondiabetics are at risk of diabetes (20%).

CONCLUSION

This study confirmed the MOH's concerns that type 2 diabetes presents local risk and brings into question historic assumptions that women are at greater risk of diabetes than men.

Health literacy and blood glucose among Guyanese emergency department patients without diagnosed diabetes: a cross-sectional study

BACKGROUND

Low health literacy is associated with worse glycemic control among patients with diabetes; the relationship between health literacy and blood glucose among patients without diagnosed diabetes, particularly in resource-limited settings, is not known. Because emergency department patients are at risk for both low health literacy and undiagnosed diabetes, we examined their relationships among emergency department patients at the Georgetown Public Hospital Corporation in Guyana.

METHODS

We conducted a cross-sectional study across random time blocks from May to August 2012 among Guyanese emergency department patients without a diagnosis of diabetes. Health literacy was assessed by the Single Item Literacy Screener (SILS, range 1-5); low health literacy was defined as SILS ≥ 3. We examined the relationships among health literacy, random blood glucose (RBG), and point-of-care glycated hemoglobin (HbA1c).

RESULTS

Of the 228 enrolled patients, 125 (54%) were female, median age was 43 years (interquartile range 38 to 53), mean body mass index (BMI) was 25.6 kg/m(2) (standard deviation 6.8 kg/m(2)), and 103 (45.2%) had low health literacy. The receiver operating characteristic area under the curve for RBG to detect elevated HbA1c (≥48mmol/mol) was 0.94 (95% CI: 0.91-0.97). After adjustment for age, sex, BMI, ethnicity, and education, the odds of having HbA1c ≥ 48 mmol/mol, consistent with undiagnosed diabetes, rose with decreasing health literacy (OR 2.2, 95% CI 1.2-3.8, p = 0.007, per point decrease in literacy).

CONCLUSION

This pilot study of Guyanese emergency department patients without diagnosed diabetes found that low health literacy was common and was associated with higher HbA1c and random blood glucose.
