The impact of diabetes on the labour force participation, savings and retirement income of workers aged 45-64 years in Australia

Chronic Diseases and Labor Force Participation Among Presenile and Senile Chinese

Background: The incidence of chronic diseases has increased dramatically due to rapid aging and lifestyle changes of China in recent decades. The population aged more than 45 years is an important participant in the labor force market, and the health status directly affects their labor force participation decision. This study aims to explore the relationship between chronic diseases and the labor force participation among the elderly Chinese population aged more than 45 years.

Method: We employ a multivariate probit (MVP) model to construct five structural equations for an analysis. The advantage of this model is that it can deal with the endogeneity of chronic diseases.

Results: Firstly, compared with the elderly, younger people are more likely to participate in the labor force market; the influence of chronic diseases is the largest for presenile women in the decision-making of labor force participation; the impact of psychological problems on labor force participation cannot be ignored, especially for men aged more than 45 years. In addition, sociodemographic factors such as geographical location and marital status also have direct effects on the probability of labor force participation while the impact of both family wealth and family number is much smaller. Finally, unhealthy lifestyles through chronic diseases have negative and indirect marginal effects on labor force participation.

Conclusions: This article proves that chronic diseases have a negative impact on the labor force participation for Chinese aged more than 45 years. The public should give more tolerance and opportunities to these groups. The population aged more than 45 years are more vulnerable and face more psychological problems, which will lead to a decline in labor force participation. Psychological health counseling and services are urgently needed. As the urban areas enjoy more social welfare, Chinese welfare policy needs to be tilted toward the rural elderly. For individuals, maintaining healthy lifestyles can help you stay away from chronic diseases and stay in the labor force market.

Identifying contemporary early retirement factors and strategies to encourage and enable longer working lives: A scoping review

AIM

Accelerating population ageing is raising concern in many countries now in relation to the availability of workers for essential work roles and responsibilities. A scoping research literature review was done to identify factors currently associated with early retirement and contemporary strategies to encourage and support longer working lives.

METHODS

Using the PRISMA-ScR Checklist, we searched the Directory of Open Access Journals and EBSCO Discovery Service for published 2013-2018 research articles using the keyword/MeSH term "early retirement"; 54 English-language articles in peer-review journals were reviewed.

RESULTS

Seven early retirement factors were revealed: Ill health, good health, workplace issues, the work itself, ageism, social norms and having achieved personal financial or pension requirement criteria. Six suggested solutions, none proven effective, were identified: Occupational health programmes, workplace enhancements, work adjustments, addressing ageism, changing social norms and pension changes.

CONCLUSIONS

The evidence base on early retirement prevention is not strong, with qualitative investigations needed for in-depth understandings of early retirement influences and mixed-methods studies needed to test early retirement prevention solutions for their effects.

IMPLICATIONS FOR PRACTICE

Until more evidence is available, every organisation should perform an early retirement risk assessment and identify current versus needed policies and programmes to encourage and enable more middle-aged and older people to work longer.

Are smoking intensity and cessation related to cataract surgical risk in diabetic patients? Findings from the 45 and Up Study

OBJECTIVES

To investigate if smoking was related to the risk of cataract surgery in diabetic patients.

METHODS

A total of 9578 diabetic participants aged 45-65 years were enrolled from the 45 and Up Study, the largest population-based cohort study in Australia. Baseline questionnaire data were linked to the Medicare Benefits Schedule (MBS) and Pharmaceutical Benefits Scheme (PBS) database, which were both available from 2004 to 2016. Cataract surgery was determined according to the MBS. Smoking status were assessed by questionnaire. Cox regression was used to evaluate the association between smoking and incidence of cataract surgery during the follow-up.

RESULTS

During a mean follow-up of 8.4 years, 995 participants underwent cataract surgery with a corresponding incidence of 12.4 cases per 1000 person-years. In all, 10.8% of participants were current smokers at baseline, 38.7% were former smokers, and 50.5% were never smokers. The incidence of cataract surgery was non-significantly higher in never-smoker compared to former or current smokers. Regression analysis showed no significant difference in cataract surgical risk among former, current, and never smokers. In addition, neither time since quitting of smoking nor age at quitting was associated with the risk of cataract surgery, although there was a marginally significant trend in a lower risk of cataract surgery with longer smoking cessation time for participant with normal weight (P for trend = 0.05).

CONCLUSIONS

Despite that smoking was found to be related to the cataract and cataract surgery in the general population, we did not find any association between smoking and cataract surgery in diabetic patients.

Impact of Diet on the Incidence of Cataract Surgery among Diabetic Patients: Findings from the 45 and Up Study

OBJECTIVE

To examine the impact of diet on the incidence of cataract surgery among the working-aged diabetic population in Australia.

METHODS

This cohort study was conducted among 8,752 participants with diabetes aged 45-65 years who were recruited to the 45 and Up Study from 2006 to 2016. The data was linked to the Medicare Benefits Schedule to obtain data on cataract surgery. Diabetes was defined as self-reported on questionnaire or diabetes medication history based on Pharmaceutical Benefits Scheme. Diet was assessed at baseline, using a self-administered questionnaire and healthy diet scores were calculated based on Australian Dietary Guidelines. Cox regression was used to evaluate the association between diet and the incidence of cataract surgery during the follow-up.

RESULTS

During a mean follow-up of 8.4 years (73,431 person-years), 914 diabetic participants underwent cataract surgery with a corresponding rate of 12.4 cases per 1,000 person-years. After adjusting for age and gender, the hazard ratios (HR) of cataract surgery for the highest compared to the lowest intake quintile of red meat and poultry were 1.24 (95% CI, 1.00-1.55) and 1.24 (95% CI, 1.02-1.51), respectively. Further adjustment for demographic, lifestyle and dietary factors resulted in no significant difference between cataract surgery risk and healthy diet scores or specific diet groups. In gender-stratified analyses, increasing consumption of red meat (HR for highest versus lowest quintile, 1.39; 95% CI, 1.00-1.93; P for trend = 0.01) and poultry (HR for highest versus lowest quintile, 1.40; 95% CI, 1.05-1.87; P for trend = 0.01) were associated with a higher risk of cataract surgery in women after adjustment of age, gender, income, education level, body mass index, hypertension, cardiovascular disease, family history of diabetes, diabetes duration, insulin use, lifestyle, and other dietary factors.

CONCLUSION

Higher consumption of red meat and poultry is related to an elevated risk of cataract surgery in the working-aged female population with diabetes.

Associations between physical activity and cataract treated surgically in patients with diabetes: findings from the 45 and Up Study

AIM

To investigate the association between physical activity (PA) and incidence of cataract surgery among patients with diabetes.

METHODS

We obtained data from all diabetic subjects aged 45-65 years from the baseline of the prospective 45 and Up Study from 2006 to 2009 and linked to the Medicare Benefits Schedule (MBS) and Pharmaceutical Benefits Scheme (PBS) until 2016. Diabetes was defined as self-reported on questionnaire or diabetes medication history based on PBS. Cataract surgery was determined based on the MBS, and metabolic equivalent intensity level number of PA sessions per week was used to assess PA. Cox regression was used to assess the association between baseline PA and cataract surgery during the follow-up.

RESULTS

A total of 9113 diabetic participants in the 45 and Up Study were included in the current analysis with a mean age of 57.3±5.2 years (43.6% female). During a mean follow-up of 8.8 years, 950 participants (10.4% of baseline) received cataract surgery with a corresponding incidence of 12.4/1000 person-years. Cox regression analysis showed that people with less PA (p=0.01), older age (p<0.001), female gender (p<0.001), higher educational level (p<0.001) and longer diabetic duration (p<0.001) had significantly higher cataract surgery risk. Participants with a PA level of ≥14 sessions per week had 19% decreased risk of cataract surgery compared to those with <5 sessions per week. Stratification analysis showed that participants with more obesity (p value for interaction=0.03), not taking insulin (p value for interaction=0.01) and without cardiovascular disease (p value for interaction=0.008) could benefit significantly more from PA in reducing their cataract surgery risk.

CONCLUSIONS

More vigorous PA was independently associated with a reduced risk of cataract surgery in working-aged patients with diabetes.

Cost-Effectiveness of Facilitated Access to a Self-Management Website, Compared to Usual Care, for Patients With Type 2 Diabetes (HeLP-Diabetes): Randomized Controlled Trial

Background

Type 2 diabetes mellitus is one of the most common long-term conditions, and costs health services approximately 10% of their total budget. Active self-management by patients improves outcomes and reduces health service costs. While the existing evidence suggested that uptake of self-management education was low, the development of internet-based technology might improve the situation.

Objective

To establish the cost-effectiveness of a Web-based self-management program for people with type 2 diabetes (HeLP-Diabetes) compared to usual care.

Methods

An incremental cost-effectiveness analysis was conducted, from a National Health Service and personal and social services perspective, based on data collected from a multi-center, two-arm individually randomized controlled trial over 12 months. Adults aged 18 or over with a diagnosis of type 2 diabetes and registered with the 21 participating general practices (primary care) in England, UK, were approached. People who were unable to provide informed consent or to use the intervention, terminally ill, or currently participating in a trial of an alternative self-management intervention, were excluded. The participants were then randomized to either usual care plus HeLP-Diabetes, an interactive, theoretically-informed Web-based self-management program, or to usual care plus access to a comparator website containing basic information only. The participants’ intervention costs and wider health care resource use were collected as well as two health-related quality of life measures: the Problem Areas in Diabetes (PAID) Scale and EQ-5D-3L. EQ-5D-3L was then used to calculate quality-adjusted life years (QALYs). The primary analysis was based on intention-to-treat, using multiple imputation to handle the missing data.

Results

In total, 374 participants were randomized, with 185 in the intervention group and 189 in the control group. The primary analysis showed incremental cost-effectiveness ratios of £58 (95% CI –411 to 587) per unit improvement on PAID scale and £5550 (95% CI –21,077 to 52,356) per QALY gained by HeLP-Diabetes, compared to the control. The complete case analysis showed less cost-effectiveness and higher uncertainty with incremental cost-effectiveness ratios of £116 (95% CI –1299 to 1690) per unit improvement on PAID scale and £18,500 (95% CI –203,949 to 190,267) per QALY. The cost-effectiveness acceptability curve showed an 87% probability of cost-effectiveness at £20,000 per QALY willingness-to-pay threshold. The one-way sensitivity analyses estimated 363 users would be needed to use the intervention for it to become less costly than usual care.

Conclusions

Facilitated access to HeLP-Diabetes is cost-effective, compared to usual care, under the recommended threshold of £20,000 to £30,000 per QALY by National Institute of Health and Care Excellence.

Performance of people with diabetes in the labor market: An empirical approach controlling for complications

This paper introduces a framework for modelling the impact that diabetes has on employment status and wages, improving the existing literature by controlling for diabetes-related complications. Using the last wave of the Spanish National Health Survey, we find that 1710 adults out of the original sample of 36,087 have diabetes, reporting higher rates of unemployment. Our empirical results suggest that persons with diabetes, compared with non-diabetic persons, have poorer labor outcomes in terms of length of unemployment and lower income. However, diabetes is not significantly associated with unemployment probabilities, suggesting that the burden of diabetes on employment is mediated by lifestyle factors and clinical and functional complications. In addition, there are mixed outcomes to this econometric approach, depending on age and gender, among other factors. This interesting finding has several implications for research and policy on strategies to get lower health inequalities.

The costs of diabetes among Australians aged 45-64 years from 2015 to 2030: projections of lost productive life years (PLYs), lost personal income, lost taxation revenue, extra welfare payments and lost gross domestic product from Health&WealthMOD2030

OBJECTIVES

To project the number of people aged 45-64 years with lost productive life years (PLYs) due to diabetes and related costs (lost income, extra welfare payments, lost taxation revenue); and lost gross domestic product (GDP) attributable to diabetes in Australia from 2015 to 2030.

DESIGN

A simulation study of how the number of people aged 45-64 years with diabetes increases over time (based on population growth and disease trend data) and the economic losses incurred by individuals and the government. Cross-sectional outputs of a microsimulation model (Health&WealthMOD2030) which used the Australian Bureau of Statistics' Survey of Disability, Ageing and Carers 2003 and 2009 as a base population and integrated outputs from two microsimulation models (Static Incomes Model and Australian Population and Policy Simulation Model), Treasury's population and labour force projections, and chronic disease trends data.

SETTING

Australian population aged 45-64 years in 2015, 2020, 2025 and 2030.

OUTCOME MEASURES

Lost PLYs, lost income, extra welfare payments, lost taxation revenue, lost GDP.

RESULTS

18 100 people are out of the labour force due to diabetes in 2015, increasing to 21 400 in 2030 (18% increase). National costs consisted of a loss of $A467 million in annual income in 2015, increasing to $A807 million in 2030 (73% increase). For the government, extra annual welfare payments increased from $A311 million in 2015 to $A350 million in 2030 (13% increase); and lost annual taxation revenue increased from $A102 million in 2015 to $A166 million in 2030 (63% increase). A loss of $A2.1 billion in GDP was projected for 2015, increasing to $A2.9 billion in 2030 attributable to diabetes through its impact on PLYs.

CONCLUSIONS

Individuals incur significant costs of diabetes through lost PLYs and lost income in addition to disease burden through human suffering and healthcare costs. The government incurs extra welfare payments, lost taxation revenue and lost GDP, along with direct healthcare costs.
