The prevalence and risk factors for diabetes mellitus in healthcare workers at Tygerberg hospital, Cape Town, South Africa: a retrospective study

Integration of point-of-care screening for type 2 diabetes mellitus and hypertension into the COVID-19 vaccine programme in Johannesburg, South Africa

BACKGROUND

South Africa grapples with a substantial burden of non-communicable diseases (NCDs), particularly type 2 diabetes (diabetes) and hypertension. However, these conditions are often underdiagnosed and poorly managed, further exacerbated by the strained primary healthcare (PHC) system and the disruptive impact of the COVID-19 pandemic. Integrating NCD screening with large-scale healthcare initiatives, such as COVID-19 vaccination campaigns, offers a potential solution, especially in low- and middle-income countries (LMICs). We investigated the feasibility and effectiveness of this integration.

METHODS

A prospective cohort study was conducted at four government health facilities in Johannesburg, South Africa. NCD screening was incorporated into the COVID-19 vaccination campaign. Participants underwent COVID-19 rapid tests, blood glucose checks, blood pressure assessments, and anthropometric measurements. Those with elevated blood glucose or blood pressure values received referrals for diagnostic confirmation at local PHC centers.

RESULTS

Among 1,376 participants screened, the overall diabetes prevalence was 4.1%, combining previously diagnosed cases and newly identified elevated blood glucose levels. Similarly, the hypertension prevalence was 19.4%, comprising pre-existing diagnoses and newly detected elevated blood pressure cases. Notably, 46.1% of participants displayed waist circumferences indicative of metabolic syndrome, more prevalent among females. Impressively, 7.8% of all participants screened were potentially newly diagnosed with diabetes or hypertension. Approximately 50% of individuals with elevated blood glucose or blood pressure successfully linked to follow-up care within four weeks.

CONCLUSION

Our study underscores the value of utilizing even brief healthcare interactions as opportunities for screening additional health conditions, thereby aiding the identification of previously undiagnosed cases. Integrating NCD screenings into routine healthcare visits holds promise, especially in resource-constrained settings. Nonetheless, concerted efforts to strengthen care linkage are crucial for holistic NCD management and control. These findings provide actionable insights for addressing the NCD challenge and improving healthcare delivery in LMICs.

Healthy behaviours, treatment, and control status of diagnosed hypertension and diabetes among the government nurses and para-health professionals of Bangladesh: A cross-sectional study

Chronic illness among health professionals (HPs) is rarely reported due to idealistic views of their role in treating and fighting diseases. This creates a gap mainly due to a lack of research on them, resulting in insufficient data at the national level, especially in Bangladesh. In this circumstance, we analyzed the data of senior staff nurses (SSNs) and para-health professionals (PHPs) to assess their healthy bahaviours, treatment, and control status of hypertension (HTN) and diabetes mellitus (DM). It was a cross-sectional study that used the census as a sampling technique. The study site was a medical university in Bangladesh located in the capital city of Dhaka. A total of 1942 government-employed health professionals working at Upazila Health Complexes participated and completed both the questionnaire and physical measurements with a response rate of 100%. Among them, 1912 (SSNs = 938 and PHPs = 974) remained for analysis after data cleaning. The prevalence of self-screening (HTN, 97.4%; DM, 81.5%), diagnosis (HTN, 20.5%; DM,15.3%), treatment (HTN, 88.7%; DM, 83.7%) and control status (HTN, 63.7%; DM, 31%) did not reveal any notable differences between SSNs and PHPs. Most of the HPs with HTN and DM failed to maintain adequate physical activity (87.4%; 86.2%), fruit and/or vegetable intake (60.7%; 59%), and healthy body weight (60.5%; 54%) respectively. Only avoidance of smoking showed a significant association with the professional categories in both hypertensives (AOR, 7.98; p = 0.001) and diabetics (AOR, 14.78; p<0.001). Although working in the field of primary health care and involved in assisting patient management, control of HTN, DM and their risk factors is not satisfactory among the SSNs and PHPs of Bangladesh. Future interventions should focus on smoking, diet, and physical activity to reduce HTN and DM in the HPs of Bangladesh.

Physical behaviors and their association with type 2 diabetes mellitus risk markers in urban South African middle-aged adults: an isotemporal substitutionapproach

INTRODUCTION

To examine the associations between physical behaviors and type 2 diabetes mellitus (T2DM) risk markers in middle-aged South African men and women.

RESEARCH DESIGN AND METHODS

This cross-sectional study included middle-aged men (n=403; age: median (IQR), 53.0 (47.8-58.8) years) and women (n=324; 53.4 (49.1-58.1) years) from Soweto, South Africa. Total movement volume (average movement in milli-g) and time (minutes/day) spent in different physical behaviors, including awake sitting/lying, standing, light intensity physical activity (LPA) and moderate-to-vigorous intensity physical activity (MVPA), were determined by combining the signals from two triaxial accelerometers worn simultaneously on the hip and thigh. All participants completed an oral glucose tolerance test, from which indicators of diabetes risk were derived. Associations between physical behaviors and T2DM risk were adjusted for sociodemographic factors and body composition.

RESULTS

Total movement volume was inversely associated with measures of fasting and 2-hour glucose and directly associated with insulin sensitivity, basal insulin clearance, and beta-cell function, but these associations were not independent of fat mass, except for basal insulin clearance in women. In men, replacing 30 min of sitting/lying, standing or LPA with the same amount of MVPA time was associated with 1.2-1.4 mmol/L lower fasting glucose and 12.3-13.4 mgl2/mUmin higher insulin sensitivity. In women, substituting sitting/lying with the same amount of standing time or LPA was associated with 0.5-0.8 mmol/L lower fasting glucose. Substituting 30 min sitting/lying with the same amount of standing time was also associated with 3.2 mgl2/mUmin higher insulin sensitivity, and substituting 30 min of sitting/lying, standing or LPA with the same amount of MVPA time was associated with 0.25-0.29 ng/mIU higher basal insulin clearance in women.

CONCLUSION

MVPA is important in reducing T2DM risk in men and women, but LPA appears to be important in women only. Longitudinal and intervention studies warranted to provide more specific PA recommendations.

Quality of Life (QoL) among Health Care Workers with Diabetes Mellitus: A Literature Review

OBJECTIVE

This scoping literature review explores the impact of diabetes mellitus (DM) on the health-related quality of life (HRQoL) of health care workers (HCWs). HCWs play a vital role in the global health care system, with the COVID-19 pandemic demonstrating their effectiveness and worth beyond any doubt. However, HCWs are among the most vulnerable members of the health care system because they are most susceptible to stress, exhaustion, and occupational health risks.

METHOD

The review was conducted in 2021 and included articles published in English in the past five years that explore diabetic HCWs' QoL and studies intended to assess the relationship between work stress and DM. In total, 27 relevant articles were found that satisfied the inclusion criteria and were critically and thematically analyzed.

RESULTS

Most DM studies have focused on the clinical management of patients, but researchers have paid little attention to the high-risk group of HCWs with diabetes. In addition to fulfilling their job mandate, HCWs are burdened with various sociological stressors that affect their QoL.

CONCLUSION

This literature review suggests DM has a significant impact on QoL in the work-life context. However, there is limited evidence to demonstrate the impact of DM on the QoL of HCWs. Thus, further research is needed in this area to improve the provision of integrated care.

Factors associated with glycemic control among South African adult residents of Mkhondo municipality living with diabetes mellitus

This study examines the rate and the influencing factors of glycemic control among adult residents living with DM in Mkhondo Municipality of South Africa.In this cross-sectional study, 157 individuals attending care for DM were recruited. Glycemic control status was categorized as poor if glycated hemoglobin (HbA1c) > 7% and very poor if HbA1c ≥ 9%. Multivariate regression analysis was used to identify the significant determinants of poor and very poor glycemic control.The majority of the study participants were females (84.71%) and above 45 years old (88.55%). The overall prevalence of poor glycemic control was 77.71% (n = 122), while very poor glycemic control occurred in 50.6% (n = 80) of the study cohort. In the multivariate logistic regression model analysis, African traditional [AOR = 0.15; 95% confidence interval (95% CI) 0.04-0.57], fast food consumption (AOR = 5.89; 95% CI 2.09-16.81), elevated total cholesterol (TC) [odds ratio (OR) = 2.33; 95% CI 1.50-5.17], elevated low-density lipoprotein cholesterol (LDL-C) (AOR = 5.28; 95% CI 1.89-14.69), and triglyceride (TG) (AOR = 4.39; 95% CI 1.48-13.00) were the independent and significant determinants of poor glycemic control. Age (AOR = 0.46; 95% CI 0.23-0.92) was the only independent and significant determinant of very poor glycemic control.We found a high rate of poor glycemic control (77.71%) possibly attributed to religious affiliation, fast food consumption, and dyslipidemia. On the contrary, about half of the study sample had very poor glycemic control (HbA1c ≥9%), which was predominant among younger cohort with diabetes mellitus. Interventions aimed at improving glycemic control in this population must also target religious practice, dietary patterns and dyslipidemia as well as tailored-approach for young people.

Patient-level predictors of diabetes-related lower extremity amputations at a quaternary hospital in South Africa

INTRODUCTION

Diabetes-related lower extremity amputation has a major psycho-social and economic cost on the patient as well as a direct impact on financial expenditure within health facilities.

AIM

This study aimed to determine the incidence and patient-related factors related to diabetes-related amputations amongst patients that were referred to the quaternary hospital between 1 January 2014 and 31 December 2015.

METHODS

A retrospective cohort study. Data were retrieved from the medical record for each diabetes patient that was managed at IALCH during the study period. The following variables were collected: sociodemographic parameters (age, gender, and ethnicity) and diabetes-related parameters (type of diabetes) and additional complications.

RESULTS

Ninety-nine patients (0, 73%) of all diabetes patients managed were new diabetes-related lower-extremity amputations. There were statistically significant increased odds of female patients (OR: 1, 7) and patients with non-insulin dependent diabetes (OR: 1, 64) to have new diabetes-related amputations. Patients older than 60 years (OR: 1, 31); African patients (OR: 1, 35) patients with cardiovascular complications (OR: 1, 04) and patients with retinopathy (OR: 1, 48) were more likely to have diabetes-related amputations but not statistically significant.

CONCLUSIONS

A combination of primary preventive strategies, early detection and appropriate management of patients with diabetes and specific guidelines on the frequency, clinical and laboratory tests required for early diagnosis and referrals with early signs of diabetes-related complicationsat primary care level will assist in reducing the long term adverse outcomes including amputations.
