A life-course approach to health: synergy with sustainable development goals.

A life-course approach to health encompasses strategies across individuals' lives that optimize their functional ability (taking into account the interdependence of individual, social, environmental, temporal and intergenerational factors), thereby enabling well-being and the realization of rights. The approach is a perfect fit with efforts to achieve universal health coverage and meet the sustainable development goals (SDGs). Properly applied, a life-course approach can increase the effectiveness of the former and help realize the vision of the latter, especially in ensuring health and well-being for all at all ages. Its implementation requires a shared understanding by individuals and societies of how health is shaped by multiple factors throughout life and across generations. Most studies have focused on noncommunicable disease and ageing populations in high-income countries and on epidemiological, theoretical and clinical issues. The aim of this article is to show how the life-course approach to health can be extended to all age groups, health topics and countries by building on a synthesis of existing scientific evidence, experience in different countries and advances in health strategies and programmes. A conceptual framework for the approach is presented along with implications for implementation in the areas of: (i) policy and investment; (ii) health services and systems; (iii) local, multisectoral and multistakeholder action; and (iv) measurement, monitoring and research. The SDGs provide a unique context for applying a holistic, multisectoral approach to achieving transformative outcomes for people, prosperity and the environment. A life-course approach can reinforce these efforts, particularly given its emphasis on rights and equity.

Une approche sanitaire fondée sur le parcours de vie englobe des stratégies tout au long de la vie des individus qui optimisent leur capacité fonctionnelle (en prenant en compte l'interdépendance de facteurs individuels, sociaux, environnementaux, temporels et intergénérationnels), assurant ainsi le bien-être et l'exercice des droits. Cette approche s'inscrit parfaitement dans les efforts déployés pour parvenir à une couverture sanitaire universelle et atteindre les objectifs de développement durable (ODD). Lorsqu'elle est correctement appliquée, une approche fondée sur le parcours de vie peut accroître l'efficacité de la première et aider à concrétiser l'ambition des seconds, en assurant notamment la santé et le bien-être pour tous à tous les âges. Sa mise en œuvre exige une compréhension commune par les individus et les sociétés de la manière dont la santé est façonnée par de multiples facteurs tout au long de la vie et d'une génération à l'autre. La plupart des études réalisées ont porté sur des maladies non transmissibles et le vieillissement des populations dans les pays à revenu élevé, ainsi que sur des aspects épidémiologiques, théoriques et cliniques. L'objectif de cet article est de montrer que l'approche sanitaire fondée sur le parcours de vie peut être élargie à toutes les tranches d'âge, toutes les questions de santé et tous les pays en s'appuyant sur une synthèse des données scientifiques existantes, les expériences de différents pays et l'avancement des stratégies et programmes en matière de santé. Un cadre conceptuel de l'approche est présenté ainsi que les conséquences de sa mise en œuvre sur: (i) la politique et l'investissement; (ii) les services et systèmes de santé; (iii) les actions locales, multisectorielles et multipartites; et (iv) les mesures, la surveillance et la recherche. Les ODD fournissent un contexte unique pour l'application d'une approche globale et multisectorielle en vue d'obtenir des résultats porteurs de transformation pour les individus, la prospérité et l'environnement. Une approche fondée sur le parcours de vie peut renforcer ces efforts, notamment parce qu'elle met l'accent sur les droits et l'équité.

Un enfoque basado en la salud para toda la vida engloba estrategias durante la vida de las personas, que optimizan su capacidad funcional (teniendo en cuenta la interdependencia de los factores individuales, sociales, ambientales, temporales e intergeneracionales), permitiendo así el bienestar y la realización de los derechos. El enfoque encaja perfectamente con los esfuerzos por lograr una cobertura sanitaria universal y cumplir los objetivos de desarrollo sostenible (ODS). Si se aplica correctamente, un enfoque para toda la vida puede aumentar la eficacia del primero y ayudar a alcanzar la visión de este último, especialmente para garantizar la salud y el bienestar en todas las edades. Su aplicación requiere una comprensión compartida entre individuos y sociedades sobre cómo la salud depende de múltiples factores presentes a lo largo de la vida y entre generaciones. La mayoría de los estudios se han centrado en las enfermedades no contagiosas, en el envejecimiento de la población en los países con ingresos altos y en cuestiones epidemiológicas, teóricas y clínicas. El objetivo de este artículo es mostrar cómo el enfoque basado en la salud para toda la vida se puede extender a todos los grupos de edades, temas de salud y países, mediante la creación de una síntesis de las pruebas científicas existentes, la experiencia en diferentes países y los avances en estrategias y programas de salud. Se presenta un marco conceptual del enfoque junto con las implicaciones para la aplicación en los siguientes campos: (i) política e inversión; (ii) servicios y sistemas de salud; (iii) acción local, multisectorial y de varias partes interesadas; y (iv) medición, supervisión e investigación. Los ODS proporcionan un contexto único para aplicar un enfoque holístico y multisectorial a fin de alcanzar unos resultados transformadores para las personas, la prosperidad y el medio ambiente. Un enfoque para toda la vida puede intensificar estos esfuerzos, sobre todo por su énfasis en los derechos y la equidad.

Socio-demographic patterns of disability among older adult populations of low-income and middle-income countries: results from World Health Survey.

OBJECTIVE: Our objective was to quantify disability prevalence among older adults of low- and middle-income countries, and measure socio-demographic distribution of disability. METHODS: World Health Survey data included 53,447 adults aged 50 or older from 43 low- and middle-income countries. Disability was a binary classification, based on a composite score derived from self-reported functional difficulties. Socio-demographic variables included sex, age, marital status, area of residence, education level, and household economic status. A multivariate Poisson regression model with robust variance was used to assess associations between disability and socio-demographic variables. RESULTS: Overall, 33.3 % (95 % CI 32.2-34.4 %) of older adults reported disability. Disability was 1.5 times more common in females, and was positively associated with increasing age. Divorced/separated/widowed respondents reported higher disability rates in all but one study country, and education and wealth levels were inversely associated with disability rates. Urban residence tended to be advantageous over rural. Country-level datasets showed disparate patterns. CONCLUSIONS: Effective approaches aimed at disability prevention and improved disability management are warranted, including the inclusion of equity considerations in monitoring and evaluation activities.

Socioeconomic inequality in disability among adults: a multicountry study using the World Health Survey.

OBJECTIVES: We compared national prevalence and wealth-related inequality in disability across a large number of countries from all income groups. METHODS: Data on 218,737 respondents participating in the World Health Survey 2002-2004 were analyzed. A composite disability score (0-100) identified respondents who experienced significant disability in physical, mental, and social functioning irrespective of their underlying health condition. Disabled persons had disability composite scores above 40. Wealth was evaluated using an index of economic status in households based on ownership of selected assets. Socioeconomic inequalities were measured using the slope index of inequality and the relative index of inequality. RESULTS: Median age-standardized disability prevalence was higher in the low- and lower middle-income countries. In all the study countries, disability was more prevalent in the poorest than in the richest wealth quintiles. Pro-rich inequality was statistically significant in 43 of 49 countries, with disability prevalence higher among populations with lower wealth. Median relative inequality was higher in the high- and upper middle-income countries. CONCLUSIONS: Integrating equity components into the monitoring of disability trends would help ensure that interventions reach and benefit populations with greatest need.

Social determinants of sex differences in disability among older adults: a multi-country decomposition analysis using the World Health Survey.

INTRODUCTION: Women represent a growing proportion of older people and experience increasing disability in their longer lives. Using a universally agreed definition of disability based on the International Classification of Functioning, Disability and Health, this paper examines how, apart from age, social and economic factors contribute to disability differences between older men and women. METHODS: World Health Survey data were analyzed from 57 countries drawn from all income groups defined by the World Bank. The final sample comprises 63638 respondents aged 50 and older (28568 males and 35070 females). Item Response Theory was applied to derive a measure of disability which ensured cross country comparability. Individuals with scores at or above a threshold score were those who experienced significant difficulty in their everyday lives, irrespective of the underlying etiology. The population was then divided into "disabled" vs. "not disabled". We firstly computed disability prevalence for males and females by socio-demographic factors, secondly used multiple logistic regression to estimate the adjusted effects of each social determinant on disability for males and females, and thirdly used a variant of the Blinder-Oaxaca decomposition technique to partition the measured inequality in disability between males and females into the "explained" part that arises because of differences between males and females in terms of age and social and economic characteristics, and an "unexplained" part attributed to the differential effects of these characteristics. RESULTS: Prevalence of disability among women compared with men aged 50+ years was 40.1% vs. 23.8%. Lower levels of education and economic status are associated with disability in women and men. Approximately 45% of the sex inequality in disability can be attributed to differences in the distribution of socio-demographic factors. Approximately 55% of the inequality results from differences in the effects of the determinants. CONCLUSIONS: There is an urgent need for data and methodologies that can identify how social, biological and other factors separately contribute to the health decrements facing men and women as they age. This study highlights the need for action to address social structures and institutional practices that impact unfairly on the health of older men and women.

Research priorities for health of people with disabilities: an expert opinion exercise.

International evidence shows that people with disabilities have many unmet health and rehabilitation needs, face barriers in accessing mainstream health-care services, and consequently have poor health. Inadequate specific information is available about the prevalence and patterns of health conditions of people with disabilities, effective interventions, and policy-relevant research about what works to improve health and functioning of people with disabilities. In view of the urgency of the issues at stake and scarcity of resources, research contributing to improvement of health of people with disabilities needs to be prioritised. We invited 82 stakeholders to list and score research options, with the priority-setting method of the Child Health and Nutrition Research Initiative. 83 research questions were assessed for answerability, applicability, sensitivity, support within the context, and equity. The leading research priority was identification of barriers that people with disabilities have in accessing health services at different levels, and finding the best possible strategies to integrate their needs into primary health-care systems and ensure local delivery. Results showed that addressing specific impairments is secondary to ensuring that health systems provide adequately for all people with disabilities. Our findings are a call for urgent attention to the issue of access to appropriate health care for people with disabilities, especially in low-income and middle-income countries.
