Comparing the mortality risks of nursing professionals with diabetes and general patients with diabetes: a nationwide matched cohort study

Educational attainment affects the diagnostic time in type 2 diabetes mellitus and the mortality risk of those enrolled in the diabetes pay-for-performance program

Most patients are diagnosed as having diabetes only after experiencing diabetes complications. Educational attainment might have a positive relationship with diabetes prognosis. The diabetes pay-for-performance (P4P) program-providing comprehensive, continuous medical care-has improved diabetes prognosis in Taiwan. This retrospective cohort study investigated how educational attainment affects the presence of diabetes complications at diabetes diagnosis and mortality risk in patients with diabetes enrolled in the P4P program. From the National Health Insurance Research Database, we identified patients aged >45 years who had received a new diagnosis of type 2 diabetes during 2002-2015; they were followed up until the end of 2017. We next used logistic regression analysis to explore whether the patients with different educational attainments had varied diabetic complication risks at diabetes diagnosis. The Cox proportional hazard model was employed to examine the association of different educational attainments in people with diabetes with mortality risk after their enrollment in the P4P program. The results indicated that as educational attainment increased, the risk of diabetes complications at type 2 diabetes diagnosis decreased gradually. When type 2 diabetes with different educational attainments joined the P4P program, high school education had the highest effect on reducing mortality risk; however, those with ≤ 6th grade education had the lowest impact.

Mortality rates and cardiovascular disease burden in type 2 diabetes by occupation, results from all Swedish employees in 2002-2015

Objective

To identify occupations where employees with type 2 diabetes have a high risk of cardiovascular disease (CVD) and mortality, and their prevalence of CVD risk factors. This study can contribute in the creation of targeted interventions at the workplace.

Research design and methods

This nationwide registry-based study included all employees with type 2 diabetes born in Sweden in 1937–1979 (n = 180,620) and followed up in 2002–2015. We calculated age-standardized incidence (per 100,000 person-years) of all-cause and CVD mortality, ischemic heart disease (IHD) and stroke across the 30 most common occupations. Information on prognostic factors was retrieved from the National Diabetes Register.

Results

In males with type 2 diabetes, mortality rates were highest in manufacturing workers (1782) and machine operators (1329), and lowest in specialist managers (633). The risk of death at age 61–70 years was 21.8% in manufacturing workers and 8.5% in managers. In females with type 2 diabetes, mortality rates were highest in manufacturing workers (1150) and cleaners (876), and lowest in writers and artists (458); the risk of death at age 61–70 years was 12.4% in manufacturing workers and 4.3% in writers and artists. The same occupations also had relatively high incidences of CVD mortality, IHD and stroke. Occupational groups with poor prognosis had high prevalence of CVD risk factors including poor glycemic control, smoking and obesity.

Conclusions

Manufacturing workers, machine operators and cleaners with type 2 diabetes have two to three times higher mortality rates than managers, writers and artists with type 2 diabetes. Major health gains would be made if targeted workplace interventions could reduce CVD risk factors in these occupations.

Incidence and prevalence of type 2 diabetes by occupation: results from all Swedish employees

AIMS/HYPOTHESIS

The workplace is a potentially important arena for prevention of type 2 diabetes and the first step is to identify occupations where the disease is common and/or risk is high. Therefore, our aim was to analyse incidence and prevalence of type 2 diabetes across all occupational groups in Sweden.

METHODS

This nationwide study included all Swedish citizens born between 1937 and 1979 and gainfully employed between 2001 and 2013 (N = 4,550,892), and followed for a diagnosis of diabetes from 2006 to 2015 (n = 201,717) through national registers. Prevalence in 2013 (mean age 51 years; range 35-67) and age-standardised incidence (per 1000 person-years) were analysed across the 30 most common occupations among men and women. Information on BMI, physical fitness and smoking was obtained through the National Conscription (mean age 18) and Medical Birth Registers (mean age 29).

RESULTS

Prevalence of type 2 diabetes was 5.2% in men and 3.2% in women; in men it was highest among motor vehicle drivers (8.8%) and in women it was highest among manufacturing workers (6.4%). Incidence varied dramatically across occupational groups. In men, it was highest among manufacturing workers (9.41) and professional drivers (9.32) and lowest among university teachers (3.44). In women, incidence was highest in manufacturing workers (7.20) and cleaners (6.18) and lowest in physiotherapists (2.20). We found major differences in the prevalence of being overweight and smoking and in the level of physical fitness across these occupational groups even at young ages.

CONCLUSIONS/INTERPRETATION

Professional drivers, manufacturing workers and cleaners have a threefold increased risk of type 2 diabetes compared with university teachers and physiotherapists. These differences most likely reflect dramatic differences in the prevalence of lifestyle risk factors. If workplace interventions could reduce weight and increase physical activity among employees in these occupations, major health gains may be made.

The general public's knowledge of diabetes mellitus: A cross-sectional study in Cameroon

OBJECTIVE

To assess the general public's level of knowledge on diabetes mellitus (DM) and identify related sources of information in Cameroon.

STUDY DESIGN

This was a cross-sectional study conducted in 2015 in two health facilities in Yaoundé and Edéa.

METHODS

We included consenting adults, except health professionals. The level of knowledge on DM was evaluated on 24 points corresponding to 24 questions addressing either DM definition, signs and symptoms, risk factors or complications.

RESULTS

Overall, 1524 persons (40.2% males) were included. Almost 99% of respondents had already heard of DM, but only 16.3% had ever received education on DM. The median score for the global knowledge was 79% (IQR 67-88). A person in the close entourage (71.3%) or a health professional (58.8%) constituted the major sources of information; school (13.3%) and media (television (23.6%), newspaper/magazine (10.0%), radio (9.6%) and internet (6.8%) were less common. Younger ages (<45years), lower levels of education, semi-urban residency, were independently associated with a lower level of knowledge on DM.

CONCLUSIONS

The general public's level of knowledge on DM may be satisfactory, though needing to be improved. Schools and media should be capitalized to educate people on DM, targeting especially young adults and the less educated.

Reduced Risks of Both Ischemic and Hemorrhagic Strokes in Nurses: A Population-Based Cohort Study in Taiwan

BACKGROUND

Nurses are typically required to address patient emergencies, and they experience high stress levels in their work, which may expose them to a higher risk of stroke. This cohort study compared the risk of stroke between nurses and the general population.

METHODS

We used the Taiwan National Health Insurance database to conduct our retrospective cohort study, and we identified 83,641 individuals in the nurse group and 334,564 individuals in the control group. For the nurse group and the control group, we used the chi-square test in addition to applying Student's t-test, in order to compare the distribution differences for the continuous variables. We estimated the hazard ratios (HRs) and 95% confidence intervals (CIs) for ischemic stroke and hemorrhagic stroke through univariate and multivariate Cox proportional-hazards regression models, with stratification according to age, sex, and comorbidity.

RESULTS

The nurse group had a lower risk of ischemic stroke and hemorrhagic stroke in the crude model (HR = 0.66, 95% CI = 0.58⁻0.75; HR = 0.58, 95% CI = 0.47⁻0.72). After adjusting the prevalent variables, the nurse group still had a lower risk of stroke (HR = 0.68, 95% CI = 0.60⁻0.77; HR = 0.59, 95% CI = 0.48⁻0.73).

CONCLUSION

The risks of both stroke types were lower in the nurse group than in the control. For stroke prevention, more frequent physical examinations are needed in order to enhance the health and well-being of people, including the nurses.
