The contributions of public health policies and healthcare quality to gender gap and country differences in life expectancy in the UK

A global analysis of the burden of ischemic heart disease attributable to diet low in ω-3 fatty acids between 1990 and 2021

AIM

Ischemic heart disease (IHD) is a major contributor to global mortality and disability, imposing a significant health and economic burden on patients and society. Despite existing treatment options including medications and surgeries, their effectiveness remains limited, with issues such as suboptimal treatment outcomes and high recurrence rates. This study aims to investigate the relationship between low dietary intake of ω-3 fatty acids and the burden of IHD, hoping to provide new insights into the prevention and treatment of IHD.

METHOD

Using the Global Burden of Disease (GBD) 2021 dataset, we examined the impact of low ω-3 dietary intake on the burden of ischemic heart disease (IHD) between 1990 and 2021globally, regionally, temporally. The Joinpoint regression model was applied to analyze the trend of IHD burden attributed to low ω-3 dietary intake over time.

RESULTS

In 2021, the global IHD-related Disability-Adjusted Life Years (DALYs) and deaths caused by a low ω-3 diet was 15,511,020(95% UI: 3,098,820 to 25,946,110) and 627,340 (95% UI: 119,540 to 1,082,740), accounting for 8.23% (95% UI: 1.64-13.52%) of all IHD-related DALYs and 6.97% (95% UI: 1.33-11.76%) of all IHD deaths, respectively. From 1990 to 2021, there was a significant upward trend in DALYs and deaths, but age-standardized DALYs and death rates showed a declining trend. Regional analysis indicated that the burden of IHD was highest in South Asia and lowest in High-Income Asia Pacific regions. At the national level, India, China, the United States, and Pakistan had a higher burden of IHD. Furthermore, as the Socio-Demographic Index (SDI) increased, the burden of IHD caused by a low ω-3 diet gradually decreased.

CONCLUSION

This study untangles a significant association between a low ω-3 diet and the burden of IHD, emphasizing the importance of promoting healthy eating habits globally. Future research should further explore the impact of dietary changes on the burden of IHD and develop targeted public health policies to reduce the burden of IHD.

Contributions of injury deaths to the changes in sex gaps in life expectancy and life disparity in the Nordic countries in the 21st century

OBJECTIVE

The objective of this study was to provide novel comparative insights on the contributions of injury deaths to the changes in sex gaps in life expectancy (SGLE) and sex gaps in life disparity (SGLD) across Nordic countries.

STUDY DESIGN

Retrospective demographic analysis of aggregated mortality data.

METHODS

To compute life expectancy (LE)/life disparity (LD), annual data on age- and sex-specific causes of death from the World Health Organization mortality database were used to construct abridged life tables for two periods: 2000-2002 and 2016-2018 (2014-2016 for Norway). The contributions of injury deaths to the changes in the SGLE and SGLD between these two periods were decomposed by age and cause using a continuous-change model.

RESULTS

Females' LE and LD advantages due to injury deaths narrowed by 0.16-0.44 (0.06-0.35) years for LE (LD) over time. While self-inflicted injuries consistently played a predominant role in contributing to the SGLE/SGLD in all countries in both periods, in all countries but Finland, transport accidents had the greatest contributions to the narrowing SGLE/SGLD. Widening SGLE due to self-inflicted injuries in Iceland and due to falls in Sweden were unique to these countries. Accounting for >20% of total contributions of injury deaths, the age group of 20-24 years had the greatest contributions to the narrowing SGLE/SGLD. Deaths due to falls in older ages and assault in younger ages generally contributed to the widening SGLE/SGLD.

CONCLUSIONS

Injury deaths, particularly transport accidents, contributed significantly to the narrowing SGLE and SGLD across Nordic countries, with cross-country variations in age- and cause-specific patterns. The results suggest the need for injury prevention policies targeting self-inflicted injuries in younger and falls in older males.

The economic burden of cancer, coronary heart disease, dementia, and stroke in England in 2018, with projection to 2050: an evaluation of two cohort studies

BACKGROUND

Cancer, coronary heart disease, dementia, and stroke are major contributors to morbidity and mortality in England. We aimed to assess the economic burden (including health-care, social care, and informal care costs, as well as productivity losses) of these four conditions in England in 2018, and forecast this cost to 2050 using population projections.

METHODS

We used individual patient-level data from the Clinical Practice Research Datalink (CPRD) Aurum, which contains primary care electronic health records of patients from 738 general practices in England, to calculate health-care and residential and nursing home resource use, and data from the English Longitudinal Study on Ageing (ELSA) to calculate informal and formal care costs. From CPRD Aurum, we included patients registered on Jan 1, 2018, in a CPRD general practice with Hospital Episode Statistics (HES)-linked records, omitting all children younger than 1 year. From ELSA, we included data collected from wave 9 (2018-19). Aggregate English resource use data on morbidity, mortality, and health-care, social care, and informal care were obtained and apportioned, using multivariable regression analyses, to cancer, coronary heart disease, dementia, and stroke.

FINDINGS

We included 4 161 558 patients from CPRD Aurum with HES-linked data (mean age 41 years [SD 23], with 2 079 679 [50·0%] men and 2 081 879 [50·0%] women) and 8736 patients in ELSA (68 years [11], with 4882 [55·9 %] men and 3854 [44·1%] women). In 2018, the total cost was £18·9 billion (95% CI 18·4-19·4) for cancer, £12·7 billion (12·3-13·0) for coronary heart disease, £11·7 billion (9·6-12·7) for dementia, and £8·6 billion (8·2-9·0) for stroke. Using 2050 English population projections, we estimated that costs would rise by 40% (39-41) for cancer, 54% (53-55) for coronary heart disease, 100% (97-102) for dementia, and 85% (84-86) for stroke, for a total of £26·5 billion (25·7-27·3), £19·6 billion (18·9-20·2), £23·5 billion (19·3-25·3), and £16·0 billion (15·3-16·6), respectively.

INTERPRETATION

This study provides contemporary estimates of the wide-ranging impact of the most important chronic conditions on all aspects of the economy in England. The data will help to inform evidence-based polices to reduce the impact of chronic disease, promoting care access, better health outcomes, and economic sustainability.

The contributions of avoidable causes of death to gender gap in life expectancy and life disparity in the US and Canada: 2001-2019

OBJECTIVES

This study measures public health policies' and healthcare system's influence, by assessing the contributions of avoidable deaths, on the gender gaps in life expectancy and disparity (GGLD and GGLD, respectively) in the United States (US) and Canada from 2001 to 2019.

METHODS

To estimate the GGLE and GGLD, we retrieved age- and sex-specific causes of death from the World Health Organization's mortality database. By employing the continuous-change model, we decomposed the GGLE and GGLD by age and cause of death for each year and over time using females as the reference group.

RESULTS

In Canada and the US, the GGLE (GGLD) narrowed (increased) by 0.9 (0.2) and 0.2 (0.3) years, respectively. Largest contributor to the GGLE was non-avoidable deaths in Canada and preventable deaths in the US. Preventable deaths had the largest contributions to the GGLD in both countries. Ischemic heart disease contributed to the narrowing GGLE/GGLD in both countries. Conversely, treatable causes of death increased the GGLE/GGLD in both countries. In Canada, "treatable & preventable" as well as preventable causes of death narrowed the GGLE while opposite was seen in the US. While lung cancer contributed to the narrowing GGLE/GGLD, drug-related death contributed to the widening GGLE/GGLD in both countries. Injury-related deaths contributed to the narrowing GGLE/GGLD in Canada but not in the US. The contributions of avoidable causes of death to the GGLE declined in the age groups 55-74 in Canada and 70-74 in the US, whereas the GGLE widened for ages 25-34 in the US.

CONCLUSION

Canada experienced larger reduction in the GGLE compared to the US attributed mainly to preventable causes of death. To narrow the GGLE and GGLD, the US needs to address injury deaths. Urgent interventions are required for drug-related death in both countries, particularly among males aged 15-44 years.

'On paper, you're normal': narratives of unseen health needs among women who have had children removed from their care

BACKGROUND

Mothers who have children removed from their care often have complex needs. These women have poor health outcomes and are dying earlier than their peers from preventable and amenable causes. Yet there is little known about how health care services might mitigate these risks. This study aimed to listen to the voices of women who had children removed from their care to understand their experiences of health and healthcare.

METHODS

We used a narrative approach to collect and analyse interview data with six mothers who had experienced child removal in England. Each participant was asked to reflect on their life and main health challenges.

RESULTS

Three narrative subplots were developed to consolidate experiences of unmet health need: (i) 'on paper you're normal': narratives of complex need, (ii) 'in my family, everyone had issues': narratives of whole family need and (iii) 'I'm still mummy, no matter where they are': narratives of maternal identity and health.

CONCLUSIONS

Findings highlight limitations within current systems of support, including a culture of distrust and women falling between the gaps of services. Women's narratives illustrate opportunities for health intervention, especially immediately following child removal.

Contributions of avoidable mortality to the sex gap in life expectancy and life disparity in Iran

BACKGROUND

Public health policies and healthcare quality play a pivotal role on the health outcome level and disparities across sociodemographic groups. However, there is little evidence on their role on disparities in life expectancy (LE) and life disparity (LD) in low and middle income countries. The present study aimed to assess the contributions of avoidable mortality, as a measure of inter-sectoral public health policies and healthcare quality, into the sex gap in LE (SGLE) and LD (SGLD) in Iran.

METHODS

Latest available data of death causes, according to the ICD codes, for Iran was obtained from the WHO mortality database for the period 2015-2016. An upper age limit of 75 years was applied to define avoidable causes of death. LD was measured as the average years of life lost at birth. The SGLE and SGLD (both females minus males) were decomposed by age and cause of death using a continuous-change model.

RESULTS

Females, on average, outlived males for 3.8 years (80.0 vs. 76.2 years) with 1.9 lower life years lost (12.6 vs. 14.4 years). Avoidable causes accounted for 2.5 (67%) and 1.5 (79%) years of the SGLE and SGLD, respectively. Among avoidable causes, injury-related deaths followed by ischaemic heart disease had the greatest contributions to both SGLE and SGLD. Across age groups, the age groups 55-59 and 60-64 accounted for the greatest contributions of avoidable causes to SGLE (0.3 years each), while age groups 20-24 and 55-59 had the greatest contributions to SGLD (0.15 years each). Lower mortality rates for females than males in age groups 50-74 years accounted for about half of the SGLE, while age groups 20-29 and 50-64 years accounted for around half of SGLD.

CONCLUSION

More than two third of the SGLE and SGLD in Iran were attributed to the avoidable mortality, particularly preventable causes. Our results suggest the need for public health policies targeting injuries in young males as well as lifestyle risk factors including smoking in middle aged males in Iran.

The social value of health: Amenable deaths and estimated the gap with the life expectancy frontier

We estimate the life expectancy gaps that can be bridged by improving the quality of public health and health care policies at the country level. Our model calculates the net effect of amenable deaths on life expectancy after controlling for time effects and factors affecting amenable deaths related to education, health policies (health expenditure to GDP and waiting lists), and per capita income in a two equation system. We further estimate the life expectancy gap that countries with lower quality health systems can bridge by catching up and reaching the existing health quality frontier and compute the social value of that upside potential.

The contributions of injury deaths to the gender gap in life expectancy and life disparity in Eastern Mediterranean Region

BACKGROUND

Injury deaths constitute a major avoidable cause of death affecting life expectancy to a different degree in men and women. This study quantified the contributions of injury deaths to the gender gap in life expectancy (GGLE) and life disparity (GGLD) in nine Eastern Mediterranean Region (EMR) countries.

METHODS

We retrieved annual data on age-sex specific causes of death from the World Health Organization mortality database for EMR countries with at least 2-year consecutive data during 2010-2019. The injury-related deaths were categorized into five groups: transport accidents, other accidental injuries, intentional self-harm, assault and events of undetermined intent. Considering women as the reference, the GGLE and GGLD were decomposed by age and causes of death, using a continuous-change model.

RESULTS

The largest and smallest GGLE were observed in Kuwait (5.2 years) and Qatar (- 1.2 years), respectively. Qatar (- 2.2 years) and Oman (0.2 years) had the highest and lowest GGLD. The highest contributions of injury deaths to the GGLE/GGLD were seen in Libya (1.8/- 1.2 years), followed by Iran (1.2/- 0.8 years). Among injury causes, transport accidents were the leading cause of GGLE in all countries but Libya and Morocco, with Iran having the greatest contributions (0.6 years). Injury deaths in men aged 15-29 years accounted for 33% [41%] (Kuwait) to 55% [65%] (Oman) of total GGLE [GGLD] attributable to injury deaths.

CONCLUSIONS

High injury deaths, particularly transport accidents, among young men contributed substantially to the GGLE and GGLD across nine EMR countries in this study. This highlights the need for implementing preventing policies to reduce the burden of injury deaths specifically in young men.

Gender equality related to gender differences in life expectancy across the globe gender equality and life expectancy

Life expectancy (LE) depends on the wider determinants of health, many of which have gendered effects worldwide. Therefore, this study aimed to investigate whether gender equality was associated with LE for women and men and the gender gap in LE across the globe. Gender equality in 156 countries was estimated using a modified global gender gap index (mGGGI), based on the index developed by the World Economic Forum between 2010 and 2021. Linear regression was used to investigate the association between the mGGGI and its economic, political, and education subindices and the gender gap in LE and women and men's LE. Overall, the mGGGI increased from 58% in 2010 to 62% in 2021. Globally, changes in the mGGGI and its economic and political subindexes were not associated with changes in the gender gap in LE or with LE for women and men between 2010 and 2020. Improvements in gender equality in education were associated with a longer LE for women and men and widening of the gender gap in LE. In 2021, each 10% increase in the mGGGI was associated with a 4.3-month increase in women's LE and a 3.5-month increase in men's LE, and thus with an 8-month wider gender gap. However, the direction and magnitude of these associations varied between regions. Each 10% increase in the mGGGI was associated with a 6-month narrower gender gap in high-income countries, and a 13- and 16-month wider gender gap in South and Southeast Asia and Oceania, and in Sub-Saharan Africa, respectively. Globally, greater gender equality is associated with longer LE for both women and men and a widening of the gender gap in LE. The variation in this association across world regions suggests that gender equality may change as countries progress towards socioeconomic development and gender equality.

Development of gender inequality in self-rated health in the life-phase of raising children in Germany from 1994 to 2018 - A decomposition analysis of socioeconomic, psychosocial and family-related influencing factors

Extensive research has documented gender inequalities in self-rated health (SRH) to the disadvantage of women. However, little research has been done on how this gender gap has changed against the backdrop of social change. Using data from the German Socio-Economic Panel Study (GSOEP), this study addressed this issue and examined time-trends in SRH between 1994 and 2018 in women (n = 117,608) and men (n = 101.404) aged 30-49 years. In addition, we analyzed the role of socioeconomic, psychosocial and family-related factors as possible mediators influencing these trends. We performed logistic regression analyses for analyzing the time-trends and applied the Karlson-Holm-Breen (KHB) method for decomposing the time effect into direct and indirect parts via mediators. Over time, the chance of reporting good as well as poor SRH remained largely stable in both genders while the majority of socioeconomic and psychosocial factors pointed towards improvement. The decomposition analysis revealed a positive effect of most of these mediators on the time trend in SRH. After controlling for the mediators, the health trend became negative, leading to a decline in the proportion of good health over time by 5.4%-point and 4.3%-point in women and men, respectively. The same pattern was observed with respect to poor SRH. For both genders, the decline of economic worries and the rise in school education contributed most to the indirect time effect. Our findings indicate a positive development of key socioeconomic and psychosocial health determinants particularly for women, but no corresponding increase in SRH. Thus, gender inequality in SRH remained largely unchanged. However, our results suggest that SRH would have developed much worse if there had been no improvements in the health determinants considered. Further studies are needed to determine what other factors may have counteracted a positive health trend and stood in the way of narrowing the gender health gap.

The gap in life expectancy and lifespan inequality between Iran and neighbour countries: the contributions of avoidable causes of death

Background

Healthcare system and intersectoral public health policies play a crucial role in improving population health and reducing health inequalities. This study aimed to quantify their impact, operationalized as avoidable deaths, on the gap in life expectancy (LE) and lifespan inequality (LI) between Iran and three neighbour countries viz., Turkey, Qatar, and Kuwait in 2015–2016.

Methods

Annual data on population and causes of deaths by age and sex for Iran and three neighbour countries were obtained from the World Health Organization mortality database for the period 2015–2016. A recently developed list by the OECD/Eurostat was used to identify avoidable causes of death (with an upper age limit of 75). The cross-country gaps in LE and LI (measured by standard deviation) were decomposed by age and cause of death using a continuous-change model.

Results

Iranian males and females had the second lowest and lowest LE, respectively, compared with their counterparts in the neighbour countries. On the other hand, the highest LIs in both sexes (by 2.3 to 4.5 years in males and 1.1 to 3.3 years in females) were observed in Iran. Avoidable causes contributed substantially to the LE and LI gap in both sexes with injuries and maternal/infant mortality represented the greatest contributions to the disadvantages in Iranian males and females, respectively.

Conclusions

Higher mortality rates in young Iranians led to a double burden of inequality –shorter LE and greater uncertainty at timing of death. Strengthening intersectoral public health policies and healthcare quality targeted at averting premature deaths, especially from injuries among younger people, can mitigate this double burden.

Gender equality and the gender gap in life expectancy in the European Union

Introduction

Life expectancy (LE) depends on the wider determinants of health, which have different impact in women and men. Therefore, this study aimed to investigate whether gender equality was correlated with LE in women and men.

Methods

Gender equality in the 27 European Union (EU) member states between 2010 and 2019 was estimated using a modified Gender Equality Index (mGEI), based on the index developed by the European Institute for Gender Equality. The correlation between this mGEI and LE and the gender gap in LE was calculated using the Spearman correlation coefficient.

Results

Between 2010 and 2019, LE increased more for men than women, which resulted in a narrowing of the gender gap in LE in the EU. During the same period, there was an increase in gender equality, as measured by the mGEI, although with substantial heterogeneity between countries. There was a strong correlation between the mGEI and the gender gap in LE (−0.880), which was explained by a stronger correlation between the mGEI and longer LE in men than in women (0.655 vs 0.629, respectively). The domains of the mGEI most strongly associated with a narrowing of the gender gap in LE were health, money and knowledge, while power was the domain with the weakest association.

Conclusions

Gender equality appears to be at least as beneficial to men as women with regard to LE, thus reinforcing the key role gender equality plays in improving population health and longevity.
