Health and rapid economic change in the late twentieth century

Direct Effect of Life-Course Socioeconomic Status on Late-Life Cognition and Cognitive Decline in the Rush Memory and Aging Project

The role of socioeconomic status (SES) across the life course in late-life cognition is unclear. We tested the hypotheses that: 1) High SES in childhood, young adulthood, midlife, and late life have independent causal effects on higher cognition level and slower cognitive decline; 2) Compared with stable low SES (referent), stable high SES has the largest estimated effect for higher cognition level and slower decline among life-course SES combinations. The Rush Memory and Aging Project enrolled 1,940 dementia-free older adults in northeastern Illinois (1997-2018). We used inverse probability-weighted marginal structural models to estimate the joint and independent effect of each life-course SES on global and domain-specific cognition. A total of 1,746 participants had, on average, 6 years of follow-up. High SES at each life-course stage starting in young adulthood had a protective estimated effect on global and domain-specific cognition intercepts. Compared with consistently low SES, consistently high SES (β = 0.64, 95% confidence interval: 0.48, 0.93) and high SES beyond childhood (β = 0.64, 95% confidence interval: 0.47, 0.83) had the largest benefit for global cognition intercepts. None of the life-course SES measures influenced rate of global or domain-specific decline. Additional understanding of life-course SES components influencing cognitive level is warranted.

Is Economic Growth Good for Population Health? A Critical Review

A large multidisciplinary literature discusses the relationship between economic growth and population health. The idea that economic growth is good for societies has inspired extensive academic debate, but conclusions have been mixed. To help shed light on the subject, this paper focuses on opportunities for consensus in this large literature. Much scholarship finds that the health-growth relationship varies according to (1) which aspect of "health" is under consideration, (2) shape (e.g., positive linear or logarithmic), (3) issues of timing (e.g., growth over the short or long term), (4) a focus on health inequalities as opposed to population averages, and (5) multivariable relationships with additional factors. After reflecting upon these findings, I propose that economic growth promotes health in some respects, for some countries, and in conjunction with other life-supporting priorities, but does not by itself improve population health generally speaking. I then argue there is already wide, interdisciplinary consensus to support this stance. Moreover, policies focusing exclusively on economic growth threaten harm to both population health and growth, which is to say that political dynamics are also implicated. Yet multivariable approaches can help clarify the bigger picture of how growth relates to health. For moving this literature forward, the best opportunities may involve the simultaneous analysis of multiple factors. The recognition of consensus around these issues would be welcome, and timely.

Cross-country evidence on the social determinants of the post-socialist mortality crisis in Europe: a review and performance-based hierarchy of variables

An unprecedented mortality crisis befell the former socialist countries between 1989 and 1995, representing one of the greatest demographic shocks of the period after the Second World War. While it is likely that country-level variation in the post-socialist mortality crisis in Eastern Europe can be explained by a constellation of political and socio-economic factors, no comprehensive review of the existing scholarly attempts at explaining these factors exists. We review 39 cross-national multi-variable peer reviewed studies of social determinants of mortality in post-socialist Europe in order to assess the social factors behind the post-socialist mortality crisis, determine the gaps in the existing literature and to make suggestions for future research. We propose a novel methodology to determine the relative importance of variables based on the ratio of significant to insignificant findings for each variable. The literature identifies inequality, welfare payments, religious composition, democracy, economic performance and unemployment as the leading factors that have a significant influence on mortality outcomes. Existing cross-country studies fail to establish a definitive connection between mortality and diets, drinking patterns, liberalisation, trust, health expenditure and war. We also point out that the level of analysis is not a neutral methodological choice but might influence the results themselves.

Comparing the socioeconomic status--health gradient among adults 50 and older across rural and urban areas of Thailand in 1994 and 2007

This paper examines associations between three indicators of socioeconomic status, education, income and bank savings, as well as one composite of these three measures, and self-assessed health for adults aged 50+ across rural and urban Thailand, comparing 1994 and 2007. Between 1994 and 2007 Thailand experienced rapid social changes that could impact on health overall and across groups, including population aging, socioeconomic development and changes in health policy. This led us to test whether overall health has improved as a result and whether the SES health gradient has changed. The data come from comparable survey sources from over seventy-thousand respondents, collected by Thailand's National Statistical Office. Generalized proportional ordered logit models were run that include up to three-way interactions of SES by year by rural versus urban location of residence are run. The three-way interactions allow for testing and of whether changes over time are due to complex intertwined effects. Results indicate that a) there has been improvement in health among the population aged 50 years and older in Thailand; b) there has been a flattening in the SES - health gradient in rural areas, and c) there has been little change in the gradient in urban areas, and if anything, there has been a widening of the relationship between income and health in urban Thailand. Divergence in the way the gradient has changed across rural and urban Thailand may point to the impact of social policy that has been aimed at poorer rural residents.

Variation of socioeconomic gradients in children's developmental health across advanced Capitalist societies: analysis of 22 OECD nations

Within societies, there is a well-established relation between socioeconomic position and a wide range of outcomes related to well-being, and this relation is known to vary in magnitude across countries. Using a large sample of nations, the authors explored whether differences in social policies explain differences in socioeconomic gradients across nations. Analyses were conducted on reading literacy in 15-year-olds, as an outcome related to cognitive development and to a host of factors that contribute to future well-being, including educational attainment and health. The results show a systematic variation in socioeconomic gradients and average scores across countries. Scores were favorable in countries with a long history of welfare state regimes, but countries where institutional change unfolded more recently and rapidly, or where welfare states are less well developed, clustered at the bottom of the rankings. Strong support was found for the "flattening up" hypothesis, which suggests that nations with higher average scores have less socioeconomic inequality in scores (or flatter gradients). Potential explanations for the observed patterns include differences between nations in the extent and distribution of income and social goods important for children's development.

What’s Politics Got to Do with It? Health, the G8, and the Global Economy

This chapter examines the pledges made by developed countries, particularly the rich club of G8 nations, to make globalization work better for the world's poor. It shows that contrary to the ringing rhetoric, they find that levels of foreign aid remain pitifully inadequate.

Economic stability and health status: evidence from East Asia before and after the 1990s economic crisis

The East Asian economies of Indonesia, Malaysia and Thailand suffered declines in their economic growth rates in 1997. The Indonesian and Thai government followed the World Bank prescription for adjustment, which included a cut-back in government spending at a time when there were significant job losses. Malaysia chose its own path to adjustment. Evidence presented in this paper shows that although the declines were short-lived that there was an impact on the health status measured by mortality rates for the populations of Indonesia and Thailand. There was little apparent impact on the health status of Malaysians. The lessons for other developing economies include the importance of social safety nets and the maintenance of government expenditure in minimising the impact of economic shocks on health.

Income distribution, public services expenditures, and all cause mortality in US States

INTRODUCTION

The objective of this paper is to investigate the relation between state and local government expenditures on public services and all cause mortality in 48 US states in 1987, and determine if the relation between income inequality and mortality is conditioned on levels of public services available in these jurisdictions.

METHODS

Per capita public expenditures and a needs adjusted index of public services were examined for their association with age and sex specific mortality rates. OLS regression models estimated the contribution of public services to mortality, controlling for median income and income inequality.

RESULTS

Total per capita expenditures on public services were significantly associated with all mortality measures, as were expenditures for primary and secondary education, higher education, and environment and housing. A hypothetical increase of 100 US dollars per capita spent on higher education, for example, was associated with 65.6 fewer deaths per 100,000 for working age men (p<0.01). The positive relation between income inequality and mortality was partly attenuated by controls for public services.

DISCUSSION

Public service expenditures by state and local governments (especially for education) are strongly related to all cause mortality. Only part of the relation between income inequality and mortality may be attributable to public service levels.

Does income inequality harm health? New cross-national evidence

The provocative hypothesis that income inequality harms population health has sparked a large body of research, some of which has reported strong associations between income inequality and population health. Cross-national evidence is frequently cited in support of this important hypothesis, but the hypothesis remains controversial, and the cross-national work has been criticized for several methodological shortcomings. This study replicates previous work using a larger sample (692 observations from 115 countries over the 1947-1996 period), a wider range of statistical controls, and fixed-effects models that address heterogeneity bias. The relationship between health and inequality shrinks when controls are included. In fixed-effects models that capture unmeasured heterogeneity, the association between income inequality and health disappears. The null findings hold for two measures of income inequality: the Gini coefficient and the share of income received by the poorest quintile of the population. Analysis of a sample of wealthy countries also fails to support the hypothesis.
