Adults with diabetes mellitus in Newfoundland and Labrador: a population-based, cross-sectional analysis.

ABSTRACT:

Background

Although the province of Newfoundland and Labrador has the highest rates of chronic disease in Canada, the current state of many chronic diseases in the province, including diabetes mellitus, has not been well explored. We profiled the demographic characteristics associated with, and the management of, diabetes in Newfoundland and Labrador, including any rural-urban differences.

Methods

We performed a population-based, cross-sectional analysis using data from the provincial Chronic Disease Registry for fiscal year 2015/16. Patients in the study sample were 20 years of age or older, with documented identifiers for age, sex and geographic location. We examined demographic characteristics, results of screening and diabetes clinical tests (glycated hemoglobin [HbA_1c], low-density lipoprotein [LDL] cholesterol and urine albumin-to-creatinine ratio) and hospitalization rates. We described and compared demographic, clinical and hospitalization variables across urban and rural residents of the province.

Results

The study sample consisted of 66 325 individuals with diabetes in Newfoundland and Labrador (mean age 64.1 yr; 56.3% rural residents). Larger proportions of rural than urban residents with diabetes were aged 65 to 79 years (41.2% v. 37.5%), were female (50.2% v. 48.7%) and were identified as having the disease by laboratory tests only (19.6% v. 13.1%). Rural residents had worse clinical test outcomes than their urban counterparts, specifically with respect to HbA_1c (mean and standard deviation [SD], 7.41% [SD 1.49] v. 7.26% [SD 1.50]) and LDL cholesterol (mean 2.46 [SD 0.95] v. mean 2.36 [SD 0.94] mmol/L). A total of 13.7% of individuals were admitted to hospital during the cohort year, with slightly more rural residents admitted for renal disease (standardized difference 0.021, 95% confidence interval 0.005 to 0.036).

Interpretation

For many individuals with diabetes in Newfoundland and Labrador, recommended targets for diabetes management are not being met, and residents in rural areas have poorer clinical outcomes. To inform the development and implementation of targeted provincial strategies for chronic disease management, further research is needed to determine how outcomes relate to the availability of primary health care services.

Project description:BackgroundTransition to adult diabetes care is a high-risk period for acute complications, yet the optimal transition care model is unknown. To gain insight into the impact on health outcomes of system-level transition processes that reflect resourcing differences, we examined acute complications in youth with diabetes across transition in 2 Canadian provinces with different transition care models.MethodsWe used linked provincial health administrative data for Ontario and Newfoundland and Labrador to create 2 parallel cohorts of youth with diabetes diagnosed before age 15 years who turned 17 between 2006 and 2011. Participants were followed until 2015 (maximum age 21 yr). We described rates of and proportion of participants with at least 1 diabetes-related hospital admission at age 15-17 years and 18-20 years, standardized according to material deprivation based on the 2006 Canadian Marginalization Index. We compared diabetes-related admissions at age 15-17 years and 18-20 years in the Ontario cohort.ResultsThe cohorts consisted of 2525 youth in Ontario and 93 in Newfoundland and Labrador. In Newfoundland and Labrador, 39 participants (42.0%) were in the lowest socioeconomic quintile, versus 326 (12.9%) in Ontario. The standardized rate of diabetes-related hospital admissions per 100 person-years was 13.5 (95% confidence interval [CI] 12.6-14.4) at age 15-17 years and 14.4 (95% CI 13.5-15.3) at age 18-20 years in Ontario, and 11.4 (95% CI 7.0-15.8) at age 15-17 years and 10.5 (95% CI 6.4-14.6) at age 18-20 years in Newfoundland and Labrador. In Ontario, there was no association between the rate (adjusted rate ratio 1.10, 95% CI 0.94-1.28) or occurrence (adjusted odds ratio 1.03, 95% CI 0.91-1.17) of diabetes-related admissions across transition.InterpretationAlthough posttransition care is delivered differently in the 2 provinces, rates of adverse events across transition were stable in both. Coordinated support during transition is needed to help mitigate adverse events for young adults in both provinces. Delivery of other health care and social services, including primary care, may be influencing the risk of adverse events after transition to adult care.

Project description:ObjectiveGlobally, 8.8% of adults were estimated to have diabetes mellitus, with the low-and middle-income countries sharing the largest burden. However, the research evidence for targeted interventions is lacking in sub-Saharan Africa, particularly in Ethiopia. Therefore, this study aimed to assess the prevalence of diabetes mellitus, disaggregated by the epidemiology of diabetes mellitus morbidity and associated factors among adults in Dire Dawa town, Eastern Ethiopia.MethodsData from a total of 872 randomly sampled adults aged 25-64 years were obtained for analysis using the World Health Organization STEPwise approach to non-communicable disease risk factors surveillance instruments. We estimated the prevalence of diabetes mellitus disaggregated by the previous diabetes mellitus diagnosis status and by the current blood sugar level control status. The bivariable and multivariable binary logistic regression model was used to identify correlates of diabetes mellitus, along with STATA version 14.2 for data management and analysis. All statistical tests were declared significant at p-value < 0.05.Results14.9% (95% confidence interval: 12.1, 17.4) of adults aged 25-64 years had diabetes mellitus in the study sample with 58.5% (95% confidence interval: 49.7, 66.7) on diabetes mellitus medication. Among adults currently taking diabetes mellitus medications, 30.3% (95% confidence interval: 19.8, 45.6) had uncontrolled diabetes mellitus. The magnitude of previously undiagnosed diabetes mellitus was 6.2% (95% confidence interval: 4.8, 8.0) in the study sample and 41.5% (95% confidence interval: 33.3, 50.3) among the diabetics. The odds of diabetes mellitus were higher among adults over the age of 55 years (adjusted odds ratio = 2.1, 95% confidence interval: 1.2, 3.6), currently married adults (adjusted odds ratio = 2.3, 95% confidence interval: 1.2, 4.4), and overweight adults (adjusted odds ratio = 1.6, 95% confidence interval: 1.1, 2.1). Adults with primary education (adjusted odds ratio = 0.4, 95% confidence interval: 0.2, 0.8) and no formal education (adjusted odds ratio = 0.5, 95% confidence interval: 0.2, 0.9) had lower odds of diabetes mellitus.ConclusionThe prevalence of diabetes mellitus among adults was high in Dire Dawa, with a third of the diabetics having poor control of their blood sugar levels and, nearly four in ten were previously undiagnosed. Adults who were overweight, currently married, and those over 55 years need to be targeted for regular diabetes health checkups and community-based screening. Also, a mechanism should be instituted to track a patient's adherence to medications and promote diabetes self-care management.

Project description:BackgroundOur objective was to examine cancer risk factor awareness and beliefs about cancer treatment, outcomes, and screening, and how these are mediated by sociodemographic variables, among Newfoundland and Labrador residents.MethodsParticipants aged 35 to 74 were recruited through Facebook advertising, and a self-administered online questionnaire was used to collect data. Descriptive statistics, Spearman rank correlations, and multivariate logistic regression analyses were performed.ResultsOf the 1048 participants who responded and met the inclusion criteria for this study, 1019 were selected for this analysis. Risk factor recognition was generally good, though several risk factors had poor awareness: being over 70 years old (53.4% respondents aware), having a low-fiber diet (65.0%), and drinking more than 1 unit of alcohol per day (62.8%). Our results showed that the participants' awareness of risk factors was significantly associated with higher income level (rs = 0.237, P < 0.001), higher education (rs = 0.231, P < 0.001), living in rural regions (rs = 0.163, P < 0.001), and having a regular healthcare provider (rs = 0.081, P = 0.010). Logistic regression showed that among NL residents in our sample, those with higher income, post-secondary education, those in very good or excellent health, and those with a history of cancer all had higher odds of having more positive beliefs about cancer treatment and outcomes. Those with a history of cancer, and those with very good or excellent health, also had higher odds of having more positive beliefs about cancer screening. Finally, compared to Caucasian/white participants, those who were non-Caucasian/white had lower odds of having more positive beliefs about cancer screening.ConclusionAmong adults in NL, there was poor awareness that low-fiber diets, alcohol, and age are risk factors for cancer. Lower income and education, rural residence, and not having a health care provider were associated with lower risk factor awareness. We also found a few associations between sociodemographic factors and beliefs about cancer treatment and outcomes or screening. We stress that while addressing awareness is necessary, so too is improving social circumstances of disadvantaged groups who lack the resources necessary to adopt healthy behaviours.
