Health Inequalities in the South African elderly: The Importance of the Measure of Social-Economic Status

A common approach when studying inequalities in health is to use a wealth index based on household durable goods as a proxy for socio-economic status. We test this approach for elderly health using data from an aging survey in a rural area of South Africa and find much steeper gradients for health with consumption adjusted for household size than with the wealth index. These results highlight the importance of the measure of socioeconomic status used when measuring health gradients, and the need for direct measures of household consumption or income in ageing studies

The effect of old-age pensions on health care utilization patterns and insurance uptake in Mexico

Introduction As old-age pensions continue to expand around the world in response to population ageing, policymakers increasingly wish to understand their impact on healthcare demand. In this paper, we examine the effects of supplemental income to older adults on healthcare use patterns, expenditures and insurance uptake in Yucatan, Mexico. Method We use a longitudinal survey for individuals aged 70 or older and an individual fixed-effects difference-in-difference approach to understand the effect of an income supplement on healthcare use patterns, out-of-pocket expenditures and health insurance uptake patterns. Results The implementation of the old-age pension was associated with increased use of healthcare with nuanced effects on the type of care. Old-age pensions increase the use of formal healthcare by 15 percentage points (95% CI 6.1 to 23.9) for those with healthcare use at baseline and by 7.5 percentage points (95% CI 3.7 to 11.3) for those without healthcare use at baseline. We find no evidence of greater out-of-pocket expenditures, likely because old-age pensions were associated with a 4.2 percentage point (95% CI 1.5 to 6.9) increase in use of public health insurance. Conclusion Old-age pensions can shift healthcare demand towards formal services and eliminate financial barriers to basic care. Pension benefits can also increase the uptake of insurance programmes. These results demonstrate how social programmes can complement each other This highlights the potential role of old-age pensions in achieving universal health coverage for individuals at older ages

Estimation of distribution of childhood diarrhoea, measles, and pneumonia morbidity and mortality by socio-economic group in low-income and middle-income countries

Background Vaccines are one of the most successful interventions in improving population health in low-income and middle-income countries (LMICs). In addition to the direct improvements in health outcomes, we are interested in their distributional effects—that is, whether vaccines promote or reduce health equity across socioeconomic groups. Empirical data on incidence and mortality of vaccine-preventable diseases across socioeconomic groups is not available. Therefore, we developed a method to estimate the distribution of childhood diseases and deaths across income groups and the benefits of three vaccines—for diarrhoea, measles, and pneumonia—in 41 LMICs. Methods For every country and disease (diarrhoea, measles, pneumonia), we estimated the distribution of cases and deaths that would occur in each income quintile had there been no immunisation or treatment programme, using both the prevalence and relative risk of a set of risk and prognostic factors. Building on these baseline estimates, we assessed the effect of three vaccines (first dose of measles vaccine, pneumococcal conjugate vaccine, and rotavirus vaccine) under five scenarios based on sets of quintile-specific immunisation coverage and uptake of disease treatment. Findings Because the prevalence of risk factors is higher in the poorest two quintiles than in the rest of the population, more disease cases and deaths would occur in the poorest two quintiles for all three diseases when vaccines or treatment are unavailable. However, we noted that current immunisation coverage and treatment utilisation rates have resulted in greater inequity in the distribution of cases and deaths. Even if in absolute terms the poorest quintiles benefit more from vaccines, the wealthier two quintiles sees a higher percentage decrease in cases and deaths. Thus, in terms of overall distribution of remaining cases and deaths with vaccine coverage, the poorest quintiles would see a higher comparative burden of disease than they would without vaccine coverage. Country-specific context, including how the baseline risks, immunisation coverage, and treatment utilisation are currently distributed across quintiles, affects how different policies translate to improvements in the distribution of cases and deaths. Interpretation Our analysis highlights several factors, including risk and prognostic factors, and vaccine and treatment coverage that would substantially contribute to the unequal distribution of childhood diseases, and we found that merely ensuring equal access to vaccines will not reduce the health outcomes gap between income quintiles. Such information can inform policies and planning of programmes that aim to improve equitable delivery of healthcare services

Measuring health and economic wellbeing in the Sustainable Development Goals era: development of a poverty-free life expectancy metric and estimates for 90 countries

Background: The Sustainable Development Goals (SDGs), adopted in September, 2015, emphasise the link between health and economic development policies. Despite this link, and the multitude of targets and indicators in the SDGs and other initiatives, few monitoring tools explicitly incorporate measures of both health and economic status. Here we propose poverty-free life expectancy (PFLE) as a new metric that uses widely available data to provide a composite measure of population health and economic wellbeing. Methods: We developed a population-level measure of PFLE and computed this summary measure for 90 countries with available data. Specifically, we used Sullivan's method, as in many health expectancy measures, to incorporate the prevalence of poverty by age and sex from household economic surveys into demographic life tables based on mortality rates from the 2015 Global Burden of Disease Study (GBD). For comparison, we also recalculated all PFLE measures using life tables from WHO and the UN. PFLE estimates for each country, stratified by sex, are the average number of poverty-free years a person could expect to live if exposed to current mortality rates and poverty prevalence in that country. Findings: The average PFLE in the 90 countries included in this study was 66·0 years (95% uncertainty interval [UI] 64·5–67·3) for females and 61·6 years (60·1–62·9) for males, whereas life expectancy estimates were 76·3 years (95% UI 74·0–78·2) for females and 71·0 years (68·7–73·0) for males. PFLE varied widely between countries, ranging from 9·9 years (95% UI 9·1–10·5) for both sexes combined in Malawi, to 83·2 years (83·0–83·5) in Iceland, the latter differing only marginally from life expectancy in that country. In 67 of 90 countries, the difference between life expectancy and PFLE was greater for females than for males, indicating that women generally live more years of life in poverty than men do. Results were consistent when using GBD, WHO, or UN life tables. Interpretation: Differences in PFLE between countries are substantially greater than differences in life expectancy. Despite general improvements in survival in most regions of the world in the past decades, the focus in the SDG era on ending poverty brings into sharp relief the importance of ensuring that years of added life are lived with at least a minimum standard of economic wellbeing. Although summary measures of population health provide overall measures of survivorship and functional health, our new measure of PFLE provides complementary information that can inform and benchmark policies seeking to improve both health and economic wellbeing.

Estimating the distribution of morbidity and mortality of childhood diarrhea, measles, and pneumonia by wealth group in low- and middle-income countries

__Background:__ Equitable access to vaccines has been suggested as a priority for low- and middle-income countries (LMICs). However, it is unclear whether providing equitable access is enough to ensure health equity. Furthermore, disaggregated data on health outcomes and benefits gained across population subgroups are often unavailable. This paper develops a model to estimate the distribution of childhood disease cases and deaths across socioeconomic groups, and the potential benefits of three vaccine programs in LMICs. __Methods:__ For each country and for three diseases (diarrhea, measles, pneumonia), we estimated the distributions of cases and deaths that would occur across wealth quintiles in the absence of any immunization or treatment programs, using both the prevalence and relative risk of a set of risk and prognostic factors. Building on these baseline estimates, we examined what might be the impact of three vaccines (first dose of measles, pneumococcal conjugate, and rotavirus vaccines), under five scenarios based on different sets of quintile-specific immunization coverage and disease treatment utilization rates. __Results:__ Due to higher prevalence of risk factors among the poor, disproportionately more disease cases and deaths would occur among the two lowest wealth quintiles for all three diseases when vaccines or treatment are unavailable. Country-specific context, including how the baseline risks, immunization coverage, and treatment utilization are currently distributed across quintiles, affects how different policies translate into changes in cases and deaths distribution. __Conclusions:__ Our study highlights several factors that would substantially contribute to the unequal distribution of childhood diseases, and finds that merely ensuring equal access to vaccines will not reduce the health outcomes gap across wealth quintiles. Such information can inform policies and planning of programs that aim to improve equitable delivery of healthcare services

Effects of changes in early retirement policies on labor force participation: the differential effects for vulnerable groups

Objectives This study investigated the effects of a national early retirement reform, which was implemented in 2006 and penalized early retirement, on paid employment and different exit pathways and examined whether these effects differ by gender, income level and health status. Methods This study included all Dutch individuals in paid employment born six months before (control group) and six months after (intervention group) the cut-off date of the reform (1 January 1950) that fiscally penalized early retirement. A regression discontinuity design combined with restricted mean survival time analysis was applied to evaluate the effect of penalizing early retirement on labor force participation from age 60 until workers reached the retirement age of 65 years, while accounting for secular trends around the threshold. Results The intervention grou

The equity impact vaccines may have on averting deaths and medical impoverishment in developing countries

With social policies increasingly directed toward enhancing equity through health programs, it is important that methods for estimating the health and economic benefits of these programs by subpopulation be developed, to assess both equity concerns and the programs’ total impact. We estimated the differential health impact (measured as the number of deaths averted) and household economic impact (measured as the number of cases of medical impoverishment averted) of ten antigens and their corresponding vaccines across income quintiles for forty-one low- and middle-income countries. Our analysis indicated that benefits across these vaccines would accrue predominantly in the lowest income quintiles. Policy makers should be informed about the large health and economic distributional impact that vaccines could have, and they should view vaccination policies as potentially important channels for improving health equity. Our results provide insight into the distribution of vaccine-preventable diseases and the health benefits associated with their prevention

Social capital, social participation and life satisfaction among Chilean older adults

OBJECTIVE To examine factors associated with social participation and their relationship with self-perceived well-being in older adults. METHODS This study was based on data obtained from the National Socioeconomic Characterization (CASEN) Survey conducted in Chile, in 2011, on a probability sample of households. We examined information of 31,428 older adults living in these households. Descriptive and explanatory analyses were performed using linear and multivariate logistic regression models. We assessed the respondents’ participation in different types of associations: egotropic, sociotropic, and religious. RESULTS Social participation increased with advancing age and then declined after the age of 80. The main finding of this study was that family social capital is a major determinant of social participation of older adults. Their involvement was associated with high levels of self-perceived subjective well-being. We identified four settings as sources of social participation: home-based; rural community-based; social policy programs; and religious. Older adults were significantly more likely to participate when other members of the household were also involved in social activities evidencing an intergenerational transmission of social participation. Rural communities, especially territorial associations, were the most favorable setting for participation. There has been a steady increase in the rates of involvement of older adults in social groups in Chile, especially after retirement. Religiosity remains a major determinant of associativism. The proportion of participation was higher among older women than men but these proportions equaled after the age of 80. CONCLUSIONS Self-perceived subjective well-being is not only dependent upon objective factors such as health and income, but is also dependent upon active participation in social life, measured as participation in associations, though its effects are moderate
