Inequalities in healthy life years in the 25 countries of the European Union in 2005: a cross-national meta-regression analysis

BACKGROUND Although life expectancy in the European Union (EU) is increasing, whether most of these extra years are spent in good health is unclear. This information would be crucial to both contain health-care costs and increase labour-force participation for older people. We investigated inequalities in life expectancies and healthy life years (HLYs) at 50 years of age for the 25 countries in the EU in 2005 and the potential for increasing the proportion of older people in the labour force. METHODS We calculated life expectancies and HLYs at 50 years of age by sex and country by the Sullivan method, which was applied to Eurostat life tables and age-specific prevalence of activity limitation from the 2005 statistics of living and income conditions survey. We investigated differences between countries through meta-regression techniques, with structural and sustainable indicators for every country. FINDINGS In 2005, an average 50-year-old man in the 25 EU countries could expect to live until 67.3 years free of activity limitation, and a woman to 68.1 years. HLYs at 50 years for both men and women varied more between countries than did life expectancy (HLY range for men: from 9.1 years in Estonia to 23.6 years in Denmark; for women: from 10.4 years in Estonia to 24.1 years in Denmark). Gross domestic product and expenditure on elderly care were both positively associated with HLYs at 50 years in men and women (p<0.039 for both indicators and sexes); however, in men alone, long-term unemployment was negatively associated (p=0.023) and life-long learning positively associated (p=0.021) with HLYs at 50 years of age. INTERPRETATION Substantial inequalities in HLYs at 50 years exist within EU countries. Our findings suggest that, without major improvements in population health, the target of increasing participation of older people into the labour force will be difficult to meet in all 25 EU countries.

Assessing the validity of the Global Activity Limitation Indicator in fourteen European countries

BackgroundThe Global Activity Limitation Indicator (GALI), the measure underlying the European indicator Healthy Life Years (HLY), is widely used to compare population health across countries. However, the comparability of the item has been questioned. This study aims to further validate the GALI in the adult European population.MethodsData from the European Health Interview Survey (EHIS), covering 14 European countries and 152,787 individuals, were used to explore how the GALI was associated with other measures of disability and whether the GALI was consistent or reflected different disability situations in different countries.ResultsWhen considering each country separately or all combined, we found that the GALI was significantly associated with measures of activities of daily living, instrumental activity of daily living, and functional limitations (P < 0.001 in all cases). Associations were largest for activity of daily living and lowest though still high for functional limitations. For each measure, the magnitude of the association was similar across most countries. Overall, however, the GALI differed significantly between countries in terms of how it reflected each of the three disability measures (P < 0.001 in all cases). We suspect cross-country differences in the results may be due to variations in: the implementation of the EHIS, the perception of functioning and limitations, and the understanding of the GALI question.ConclusionThe study both confirms the relevance of this indicator to measure general activity limitations in the European population and the need for caution when comparing the level of the GALI from one country to another.

Social inequalities in disability-free life expectancy in the French male population, 1980-1991.

We calculate aggregate indicators of population health for occupational groups to gauge changes in health disparities during the 1980–1991 period. The study is based on the experiences of French adult men in three major occupational classes: managers, manual workers, and an intermediary occupational group. Life table models show that managers have longer life expectancy and dis-abilityfree life expectancy (DFLE) than manual workers, and a shorter life expectancy with disability. The concurrent increases in life expectancy and DFLE during the period maintained the occupational disparities in health; the years lived with disability, however, declined for all groups, as for the entire French population.

Gender differences in healthy life years within the EU: an exploration of the “health–survival” paradox

ObjectivesTo evaluated the female–male health–survival paradox by estimating the contribution of women’s mortality advantage versus women’s disability disadvantage.MethodsDisability prevalence was measured from the 2006 Survey on Income and Living Conditions in 25 European countries. Disability prevalence was applied to life tables to estimate healthy life years (HLY) at age 15. Gender differences in HLY were split into two parts: that due to gender inequality in mortality and that due to gender inequality in disability. The relationship between women’s mortality advantage or disability disadvantage and the level of population health between countries was analysed using random-effects meta-regression.ResultsWomen’s mortality advantage contributes to more HLY in women; women’s higher prevalence of disability reduces the difference in HLY. In populations with high life expectancy women’s advantage in HLY was small or even a men’s advantage was found. In populations with lower life expectancy, the hardship among men is already evident at young ages.ConclusionsThe results suggest that the health–survival paradox is a function of the level of population health, dependent on modifiable factors.

The reliability of the Minimum European Health Module.

Objectives:The Minimum European Health Module (MEHM) consists of 3 global questions concerning 3 health domains: self-perceived health, chronic conditions and long-term activity limitation. The objective of this paper is to evaluate the reliability of the MEHM.Methods:Participants of the Belgian Food Consumption Survey were interviewed twice: 170 individuals were selected for the MEHM reliability evaluation. For each of the 3 questions Pearson and Kappa coefficients were estimated. Analyses were stratified by gender, age, education, language and time between the interviews.Results:The Pearson correlations are between 0.73 and 0.81. The Kappa estimates are good or excellent: 0.74 (self-perceived health), 0.77 (chronic conditions) and 0.68 (activity limitation). Also stratified analyses indicated in general an acceptable reliability.Conclusion:The MEHM has an acceptable reliability.

The Global Activity Limitation Index measured function and disability similarly across European countries

OBJECTIVE This work aims to validate and increase understanding of the Global Activity Limitation Index (GALI), an activity limitation measure from which the new structural indicator Healthy Life Years is generated. STUDY DESIGN AND SETTING Data from the Survey of Health and Retirement in Europe, covering 11 European countries and 27,340 individuals older than 50 years, was used to investigate how the GALI was associated with other existing measures of function and disability and whether the GALI was consistent or reflected different levels of health in different countries. RESULTS The GALI was significantly associated with the two subjective measures of activities of daily living score and instrumental activities of daily living (IADL) score, and the two objective measures of maximum grip strength and walking speed (P<0.001 in all cases). The GALI did not differ significantly between countries in terms of how it reflected three of the health measures, with the exception being IADL. CONCLUSION The GALI appears to satisfactorily reflect levels of function and disability as assessed by long-standing objective and subjective measures, both across Europe and in a similar way between countries.

Trends in disability-free life expectancy at age 65 in France: consistent and diverging patterns according to the underlying disability measure

Disability-free life expectancy estimates (DFLE) are summary measures to monitor whether a longer life expectancy (LE) is associated with better health or whether additional years of life are years of poor health or disability. Disability is a generic term defined as the impact of disease or injury on the functioning of individuals. It covers various situations from the rather common functional limitations to restrictions in daily activities and finally dependency. Disentangling these dimensions is essential to monitor future needs of care and assistance; but this is not always feasible since surveys do not systematically cover a large range of disability dimensions in their questionnaires. This study aims to cover different disability dimensions by using data from different French population surveys. We computed ten disability-free life expectancies, based on both specific and generic disability indicators from four population health surveys, in order to describe and compare trends and patterns for France over the 1980s and the 1990s. We used the Sullivan method to combine prevalence of disability and life tables. In 2000, two thirds of total LE at age 65 are years with physical or sensory functional limitations and 10% are years with restrictions in personal care activities. Trends in DFLE over the two last decades seem to have remained stable for moderate levels of disability and to have increased for more severe levels of disability or activity restrictions. We found that patterns are consistent from one survey to the other when comparing indicators reflecting similar disability situations.

Inequalities in health expectancies at older ages in the European Union: findings from the Survey of Health and Retirement in Europe (SHARE)

Background Life expectancy gaps between Eastern and Western Europe are well reported with even larger variations in healthy life years (HLY). Aims To compare European countries with respect to a wide range of health expectancies based on more specific measures that cover the disablement process in order to better understand previous inequalities. Methods Health expectancies at age 50 by gender and country using Sullivans method were calculated from the Survey of Health and Retirement in Europe Wave 2, conducted in 2006 in 13 countries, including two from Eastern Europe (Poland, the Czech Republic). Health measures included co-morbidity, physical functional limitations (PFL), activity restriction, difficulty with instrumental and basic activities of daily living (ADL), and self-perceived health. Cluster analysis was performed to compare countries with respect to life expectancy at age 50 (LE50) and health expectancies at age 50 for men and women. Results In 2006 the gaps in LE50 between countries were 6.1 years for men and 4.1 years for women. Poland consistently had the lowest health expectancies, however measured, and Switzerland the greatest. Polish women aged 50 could expect 7.4 years fewer free of PFL, 6.2 years fewer HLY, 5.5 years less without ADL restriction and 9.5 years less in good self-perceived health than the main group of countries (Austria, Belgium, Denmark, France, Germany, Italy, the Netherlands, Spain, Sweden). Conclusions Substantial inequalities between countries were evident on all health expectancies. However, these differed across the disablement process which could indicate environmental, technological, healthcare or other factors that may delay progression from disease to disability.

The joint action on healthy life years (JA: EHLEIS).

BackgroundLife expectancy has been increasing during the last century within the European Union (EU). To measure progress in population health it is no longer sufficient to focus on the duration of life but quality of life should be considered. Healthy Life Years (HLY) allow estimating the quality of the remaining years that a person is expected to live, in terms of being free of long-standing activity limitation. The Joint Action on Healthy Life Years (JA: EHLEIS) is a joint action of European Member States (MS) and the European Union aiming at analysing trends, patterns and differences in HLY, as well as in other Summary Measures of Population Health (SMPH) indicators, across the European member states.MethodsThe JA: EHLEIS consolidates existing information on life and health expectancy by maximising the European comparability; by analysing trends in HLY within the EU; by analysing the evolution of the differences in HLY between Member States; and by identifying both macro-level as micro-level determinants of the inequalities in HLY. The JA: EHLEIS works in collaboration with the USA, Japan and OECD on the development of new SMPHs to be used globally. To strengthen the utility of the HLY for policy-making, annual meetings with policy-makers are planned.ResultsThe information system allows the estimation of a set of health indicators (morbidity and disability prevalence, life and health expectancies) for Europe, Member States and shortly their regional levels. An annual country report on HLY in the national languages is available. The JA: EHLEIS is developing statistical attribution and decomposition tools which will be helpful to determine the impact of specific diseases, life styles or other determinants on differences in HLY. Through a set of international workshops the JA: EHLEIS aims to develop a blueprint for an international harmonized Summary Measure of Population Health.ConclusionThe JA: EHLEIS objectives are to monitor progress towards the headline target of the Europe 2020 strategy of increasing HLY by 2 years by 2020 and to support policy development by identifying the main determinants of active and healthy ageing in Europe.

Mind the gap—reaching the European target of a 2-year increase in healthy life years in the next decade

Background: The European Innovation Partnership on Active and Healthy Ageing seeks an increase of two healthy life years (HLY) at birth in the EU27 for the next 10 years. We assess the feasibility of doing so between 2010 and 2020 and the differential impact among countries by applying different scenarios to current trends in HLY. Methods: Data comprised HLY and life expectancy (LE) at birth 2004–09 from Eurostat. We estimated HLY in 2010 in each country by multiplying the Eurostat projections of LE in 2010 by the ratio HLY/LE obtained either from country and sex-specific linear regression models of HLY/LE on year (seven countries retaining same HLY question) or extrapolating the average of HLY/LE in 2008 and 2009 to 2010 (20 countries and EU27). The first scenario continued these trends with three other scenarios exploring different HLY gap reductions between 2010 and 2020. Results: The estimated gap in HLY in 2010 was 17.5 years (men) and 18.9 years (women). Assuming current trends continue, EU27 HLY increased by 1.4 years (men) and 0.9 years (women), below the European Innovation Partnership on Active and Healthy Ageing target, with the HLY gap between countries increasing to 18.3 years (men) and 19.5 years (women). To eliminate the HLY gap in 20 years, the EU27 must gain 4.4 HLY (men) and 4.8 HLY (women) in the next decade, which, for some countries, is substantially more than what the current trends suggest. Conclusion: Global targets for HLY move attention from inter-country differences and, alongside the current economic crisis, may contribute to increase health inequalities.
