Background The Global Burden of Disease Study 2013 (GBD 2013) aims to bring together all available epidemiological data using a coherent measurement framework, standardised estimation methods, and transparent data sources to enable comparisons of health loss over time and across causes, age–sex groups, and countries. The GBD can be used to generate summary measures such as disability-adjusted life-years (DALYs) and healthy life expectancy (HALE) that make possible comparative assessments of broad epidemiological patterns across countries and time. These summary measures can also be used to quantify the component of variation in epidemiology that is related to sociodemographic development. Methods We used the published GBD 2013 data for age-specific mortality, years of life lost due to premature mortality (YLLs), and years lived with disability (YLDs) to calculate DALYs and HALE for 1990, 1995, 2000, 2005, 2010, and 2013 for 188 countries. We calculated HALE using the Sullivan method; 95% uncertainty intervals (UIs) represent uncertainty in age-specific death rates and YLDs per person for each country, age, sex, and year. We estimated DALYs for 306 causes for each country as the sum of YLLs and YLDs; 95% UIs represent uncertainty in YLL and YLD rates. We quantified patterns of the epidemiological transition with a composite indicator of sociodemographic status, which we constructed from income per person, average years of schooling after age 15 years, and the total fertility rate and mean age of the population. We applied hierarchical regression to DALY rates by cause across countries to decompose variance related to the sociodemographic status variable, country, and time. Findings Worldwide, from 1990 to 2013, life expectancy at birth rose by 6·2 years (95% UI 5·6–6·6), from 65·3 years (65·0–65·6) in 1990 to 71·5 years (71·0–71·9) in 2013, HALE at birth rose by 5·4 years (4·9–5·8), from 56·9 years (54·5–59·1) to 62·3 years (59·7–64·8), total DALYs fell by 3·6% (0·3–7·4), and age-standardised DALY rates per 100 000 people fell by 26·7% (24·6–29·1). For communicable, maternal, neonatal, and nutritional disorders, global DALY numbers, crude rates, and age-standardised rates have all declined between 1990 and 2013, whereas for non–communicable diseases, global DALYs have been increasing, DALY rates have remained nearly constant, and age-standardised DALY rates declined during the same period. From 2005 to 2013, the number of DALYs increased for most specific non-communicable diseases, including cardiovascular diseases and neoplasms, in addition to dengue, food-borne trematodes, and leishmaniasis; DALYs decreased for nearly all other causes. By 2013, the five leading causes of DALYs were ischaemic heart disease, lower respiratory infections, cerebrovascular disease, low back and neck pain, and road injuries. Sociodemographic status explained more than 50% of the variance between countries and over time for diarrhoea, lower respiratory infections, and other common infectious diseases; maternal disorders; neonatal disorders; nutritional deficiencies; other communicable, maternal, neonatal, and nutritional diseases; musculoskeletal disorders; and other non-communicable diseases. However, sociodemographic status explained less than 10% of the variance in DALY rates for cardiovascular diseases; chronic respiratory diseases; cirrhosis; diabetes, urogenital, blood, and endocrine diseases; unintentional injuries; and self-harm and interpersonal violence. Predictably, increased sociodemographic status was associated with a shift in burden from YLLs to YLDs, driven by declines in YLLs and increases in YLDs from musculoskeletal disorders, neurological disorders, and mental and substance use disorders. In most country-specific estimates, the increase in life expectancy was greater than that in HALE. Leading causes of DALYs are highly variable across countries. Interpretation Global health is improving. Population growth and ageing have driven up numbers of DALYs, but crude rates have remained relatively constant, showing that progress in health does not mean fewer demands on health systems. The notion of an epidemiological transition—in which increasing sociodemographic status brings structured change in disease burden—is useful, but there is tremendous variation in burden of disease that is not associated with sociodemographic status. This further underscores the need for country-specific assessments of DALYs and HALE to appropriately inform health policy decisions and attendant actions.

This paper integrates investments in health to a standard growth model where physical and human capital investments are the combined engines of growth. It shows the existence of two distinct health regimes separated by an 'Epidemiological Transition'. The various patterns of the transition identified in the epidemiological literature can be mapped into the model. The model also leads to the important hypothesis that the epidemiological transition may induce an economy to switch to a modern growth regime.

The Economics of Non-Communicable Diseases in Indonesia provides new data on the economic burden of NCDs in the country, and puts it in perspective by drawing a comparison with India and China. With this new addition to the series on the economics of NCDs, the World Economic Forum aims to advance the understanding of the expected economic output loss at the country level, particularly in countries in economic and epidemiological transition. The evidence presented provides a starting point in reorienting the dialogue on investing in healthy living and NCD prevention in Indonesia towards the view that a healthy population is an important factor for sustainable growth.

A transição demográfica e epidemiológica da população portuguesa tem e terá um enorme impacto na utilização dos recursos de saúde. Atualmente, as pessoas idosas representam um dos grupos etários com taxas de internamento hospitalar mais significativos. Contudo, os dados sobre a hospitalização destas pessoas têm demonstrado resultados de saúde negativos, nomeadamente, o declínio funcional e cognitivo e o risco elevado de eventos adversos. Os/as enfermeiros/as têm um papel crucial na mudança desta realidade. Deste modo, a associação entre o contexto no qual decorre o cuidado de enfermagem geriátrica e os resultados deste cuidado relativos a/os utentes, enfermeiros/as e organizações têm sido proficuamente documentados. Algumas estratégias para promover a qualidade do cuidado geriátrico e a segurança das pessoas idosas hospitalizadas consistem em avaliar e (re)criar o ambiente de trabalho geriátrico dos/as enfermeiros/as (AGTE) e capacitar e treinar estes/as profissionais no cuidado à pessoa idosa. Embora, internacionalmente, os dados demonstrem a associação entre as características de hospitais e/ou enfermeiros/as e o AGTE, não existem estudos em Portugal nesta área, bem como sobre o conhecimento e as atitudes destes profissionais no contexto hospitalar. Por conseguinte, este estudo teve como objetivos: 1) traduzir, adaptar culturalmente e validar as escalas que compõem o questionário Geriatric Institucional Assessment Proflie (GIAP) para a população portuguesa; 2) analisar o AGTE (fatores intrínsecos e extrínsecos) que apoiam ou dificultam a adoção das melhores práticas geriátricas em hospitais portugueses; 3) analisar as atitudes e conhecimento de enfermeiros/as acerca de quatro síndromes geriátricas (úlceras de pressão, distúrbio do sono, contenção física e incontinência), destacando as boas práticas e os problemas encontrados nos hospitais portugueses; 4) analisar a relação entre as variáveis demográficas, profissionais e as características dos hospitais e as escalas que compõem o GIAP – versão portuguesa; 5) conhecer as perceções de enfermeiros/as acerca do cuidado às pessoas idosas hospitalizadas e dos obstáculos enfrentados para desenvolver um cuidado de boa qualidade; e 6) analisar a relação entre a perceção de enfermeiros/as sobre o AGTE e o conhecimento e atitudes geriátricas destes profissionais em função da região e unidade de internamento. Este estudo foi desenvolvido com base num método quantitativo do tipo exploratório-descritivo, transversal, prospetivo e correlacional. A amostra foi constituída por 1.068 enfermeiros/as de cinco hospitais da região norte e centro do país. A recolha de dados foi desenvolvida através de autopreenchimento do GIAP – versão portuguesa. De entre os principais resultados destacam-se: 1) a obtenção de um instrumento válido e fiável para avaliar o AGTE e conhecimentos e atitudes geriátricas; 2) a perceção de enfermeiros/as sobre o cuidado às pessoas idosas como sendo predominantemente negativa; 3) a perceção de enfermeiros/as sobre o apoio insuficiente dos líderes hospitalares para promover um AGTE favorável; 4) o cuidado a pessoas idosas com comportamentos inadequados e o uso de recursos geriátricos como os principais fatores que influenciam a eficácia e a qualidade do cuidado geriátrico; 5) a lacuna de conhecimento e atitudes negativas de enfermeiros/as acerca das quatro síndromes geriátricas; 6) a conceptualização de um modelo sobre a associação das características de enfermeiros/as, dos hospitais do estudo e das perceções destes/as profissionais sobre o cuidado geriátrico com o AGTE e o conhecimento e atitudes geriátricos; 7) a falta de apoio familiar, a descontinuidade e a escassez de tempo para o cuidado como principais obstáculos no cuidado à pessoa idosa hospitalizada; e 8) o perfil de cuidado geriátrico nos hospitais da região norte e centro de Portugal como tendencialmente homogéneo. Os resultados deste estudo sustentam a necessidade de um maior investimento dos decisores políticos, administradores hospitalares e docentes de Enfermagem na capacitação dos/as enfermeiros/as para o cuidado geriátrico e na promoção de um AGTE mais favorável. Também oferece recomendações significativas nos domínios da decisão política, da gestão institucional e da prática profissional que devem ser alvo de uma discussão alargada entre os vários agentes com responsabilidade nestes domínios. Espera-se que este estudo possa contribuir para a promoção de um contexto favorável ao desenvolvimento de um cuidado de enfermagem geriátrica de boa qualidade às pessoas hospitalizadas.

This article presents selected findings and lessons from a cardiovascular research and prevention program initiated in 1989 in the Republic of Seychelles, a country in demographic and epidemiological transition. Rapid and sustained aging of the population (e.g., two-fold increase of people aged 30-39 from 1979 to 1995) implies, over the next few decades, further dramatic increase of the burden of chronic diseases, particularly cardiovascular disease (CVD). Epidemiological surveillance shows high age-specific rates of CVD (particularly stroke), high prevalence of peripheral atherosclerosis (plaques in carotid and femoral arteries), high prevalence of classical modifiable risk factors in the adult population (particularly hypertension), and substantial proportions of children with overweight. Stagnant life expectancy in men and an increase in women have been observed over the last two decades; this occurred despite largely improved health services and reduced infant mortality rates, and may reflect the large CVD burden found in middle-aged men (less so in middle-aged women). A national program of prevention of CVD has been initiated since 1991, which includes a mix of interventions to reduce risk factors in the general population and in high-risk individuals. Substantial research to back the prevention program indeed shows, at the moment, epidemiological patterns in Seychelles similar to those observed in Western countries (e.g., an association between peripheral atherosclerosis [as a proxy of CVD] and low density lipoprotein-cholesterol, smoking, diabetes, and [inversely] walking). This clearly supports the view that promotion of healthy lifestyles and control of conventional risk factors should be the main targets for CVD prevention and control.

La mortalité aux jeunes âges devenant de plus en plus faible, l’augmentation de l’espérance de vie est de plus en plus dépendante des progrès en mortalité aux âges avancés. L’espérance de vie à 65 ans et à 85 ans n’a cependant pas connu un rythme de progression continu depuis les trois dernières décennies. Ces changements dans l’évolution de l’espérance de vie proviennent de changements dans les tendances de certaines causes de décès et de leurs interactions. Ce mémoire analyse la contribution des causes de décès aux changements qu’a connus l’espérance de vie, mais aussi l’évolution spécifique des taux de mortalité liés aux principales causes de décès au Canada entre 1979 et 2007. Finalement, une analyse de l’implication de ces changements dans un contexte de transition épidémiologique sera réalisée, par un questionnement sur le fait que l’on assiste ou non au passage de certaines pathologies dominantes à d’autres. La réponse à ce questionnement se trouve dans l’étude de l’évolution par âge et dans le temps des causes de décès. Les résultats montrent que les progrès en espérance de vie à 65 ans et à 85 ans sont encore majoritairement dus à la diminution de la mortalité par maladies cardiovasculaires. Toutefois, ces dernières causes de décès ne sont pas les seules à contribuer aux progrès en espérance de vie, puisque les taux de mortalité dus aux dix principales causes de décès au Canada ont connu une diminution, bien qu’elles n’aient pas toutes évolué de la même manière depuis 1979. On ne semble ainsi pas passer d’un type de pathologies dominantes à un autre, mais à une diminution générale de la mortalité par maladies chroniques et à une diversification plus importante des causes de décès à des âges de plus en plus avancés, notamment par la diminution des «grandes» causes de décès.

Contexte : L’hypertension artérielle (HTA) est reconnue comme un important facteur de risque des maladies cardiovasculaires et de la mortalité prématurée. Les données montrent qu’un adulte sur 4 dans le monde souffrait d’hypertension en 2000 et ce chiffre serait en augmentation. Dans les pays africains, les estimations prévoient une progression plus rapide de la prévalence de l’HTA engendrant ainsi un problème additionnel à gérer pour le système de santé qui est toujours aux prises avec les maladies transmissibles. Les progrès économiques et l’urbanisation semblent entraîner des modifications des habitudes de vie dans ces pays qui seraient associés à une émergence des maladies non transmissibles, dont l’HTA. Le Burkina Faso, pays de l’Afrique de l’Ouest classé comme un pays à faibles revenus, aurait amorcé sa transition épidémiologique et il importe de faire un état sur les maladies non transmissibles en émergence. Afin de contribuer à la connaissance des aspects épidémiologiques de l’HTA au Burkina Faso, trois objectifs spécifiques ont été retenus pour la présente recherche : 1) Estimer la prévalence de l’HTA et identifier les facteurs associés dans la population rurale et la population semi-urbaine du Système de Surveillance démographique et de Santé de Kaya (Kaya HDSS) ; 2) Déterminer la différence de prévalence de l’HTA entre la zone lotie et la zone non lotie de la ville de Ouagadougou et identifier les facteurs associés ; 3) Déterminer la détection, le traitement, le contrôle de l’HTA et estimer la fréquentation des centres de santé par les personnes hypertendues nouvellement dépistées dans la population adulte du Centre Nord du Burkina Faso. Méthodologie : Le cadre de notre recherche est le Burkina Faso. Deux sites ont fait l’objet de nos investigations. Kaya HDSS, situé dans la région du Centre Nord du Burkina Faso a servi de site pour les enquêtes ayant permis l’atteinte du premier et du troisième objectif général. Une étude transversale a été menée en fin 2012 sur un échantillon aléatoire de 1645 adultes résidents du site. Un entretien suivi de mesures anthropométriques et de la pression artérielle (PA) ont été réalisés au domicile des participants. Toutes les personnes qui avaient une PA élevée (PA systolique ≥ 140 mm Hg et/ou PA diastolique ≥ 90 mm Hg) et qui n’avaient pas été diagnostiquées auparavant ont été référées à une formation sanitaire. Un second entretien a été réalisé avec ces personnes environ un mois après. Pour le second objectif général, c’est le système de surveillance démographique et de santé de Ouagadougou (Ouaga HDSS) qui a été retenu comme site. Ouaga HDSS couvre 5 quartiers de la zone nord de Ouagadougou. Une étude transversale a été réalisée en 2010 sur un échantillon aléatoire représentatif de la population adulte résidante du site (N = 2041). Des entretiens suivis de mesures anthropométriques et de la PA ont été réalisés durant l’enquête. Résultats : Notre premier article examine la prévalence de l’HTA et les facteurs associés en milieu rural et en milieu semi-urbain. Au total 1481 participants ont été dépistés et la prévalence totale pondérée était de 9,4 % (95 % IC : 7,3 % - 11,4 %) avec une grande différence entre le milieu semi-urbain et le milieu rural : un adulte sur 10 était hypertendu en milieu semi-urbain contre un adulte sur 20 en milieu rural. L’analyse multivariée nous a permis d’identifier l’âge avancé, le milieu semi-urbain et l’histoire familiale de l’HTA comme des facteurs de risque. Dans le deuxième article, nous avons déterminé la différence entre la zone lotie et la zone non lotie du milieu urbain en ce qui concerne l’HTA. Sur 2 041 adultes enquêtés, la prévalence totale est estimée à 18,6 % (95 % IC : 16,9 % - 20,3 %). Après ajustement avec l’âge, il n’y avait pas de différence de prévalence entre la zone lotie et la zone non lotie de la ville de Ouagadougou. Dans ce milieu urbain, l’obésité et l’inactivité physique sont confirmées comme des facteurs à risque. En plus des personnes âgées qui constituent un groupe à risque, les migrants venant du milieu rural et les veuves ont été identifiés comme des personnes à risque. Notre troisième article examine la détection, le traitement, le contrôle de l’HTA ainsi que la fréquentation des structures de santé par les personnes nouvellement dépistées hypertendues dans le milieu non urbain. Sur les 1481 participants à l’étude, 41 % n’avaient jamais mesuré leur PA. Sur les 123 participants (9,4 %) dépistés comme hypertendus, 26,8 % avaient déjà bénéficié d’un diagnostic et 75,8 % de ces derniers étaient sous traitement anti hypertensif. Parmi les participants sous traitement, 60 % (15 sur 25) avaient leur PA sous contrôle. Le suivi de 2 mois a permis de retrouver 72 des 90 personnes nouvellement dépistées. Seulement 50 % ont été en consultation et parmi ces derniers 76 % (28 personnes sur les 37) ont reçu une confirmation de leur hypertension. Conclusion : Notre recherche montre l’évolution de l’HTA en fonction du niveau d’urbanisation de la population. Même si les maladies infectieuses restent la priorité du système de santé, la lutte contre l’HTA doit s’inscrire dans un cadre général de lutte contre les maladies cardiovasculaires. Cette lutte doit être amorcée maintenant avant que des proportions inquiétantes ne soient atteintes. Des actions de prévention telles que la promotion de saines habitudes de vie, le dépistage de masse et un renforcement des capacités du système de soins sont à mettre en œuvre.

En Colombia como en otros países del mundo se está viviendo un proceso de transición epidemiológica y cada vez es más importante la población, aumentando el número de adultos mayores, en los que la depresión es una enfermedad que genera impacto en la morbililidad y mortalidad, y pocos estudios nacionales se han enfocado en analizar su comportamiento y sus factores asociados. Metodología: Estudio de corte transversal sobre los datos de la encuesta nacional de demografía y salud del año 2010 (ENDS 2010) que encuesto 50.000 hogares con 17.574 adultos mayores encuestados. Se realizó una regresión logística binaria y múltiple para establecer las variables asociadas a la depresión. Resultados: Se encontró una prevalencia global de 9,5%, siendo mayor para el sexo femenino (11,5%, OR =1,74), menor prevalencia de depresión a medida que aumenta la escolaridad (OR=0.14), mayor depresión en presencia de discapacidad (OR=14,21) y en las comorbilidades como enfermedades cerebrales (OR=2.09), cardiacas (OR=1.49), diabetes (OR=1.19), Alzheimer (OR=2,13) entre otras, no se encontró asociación con variables como edad, estado civil. Discusión: El comportamiento de la depresión en adultos mayores en la población estudiada es similar a la de otros países, se deben hacer estudios prospectivos y de intervención para establecer mejor las variables relacionadas.

The relationship between sanitation policies (access and quality) and health in Brazilian municipalities was estimated from 2003 to 2010 using a panel data model with corrections for missing data. The results suggest a limited effect of sanitation policy on health. Compared with results from the literature, we found that the worsening quality of water appears to be associated with increased rates of mortality and hospitalization for children up to one month of age. Improvements in sewage sanitation have reduced the mortality and morbidity rates in children aged one to four. Improved access to piped water is associated with decreased hospitalization related to dysentery and acute respiratory infections (ARI) and does not have an effect on child mortality. Finally, epidemiological transition is only supported by weak evidence, including a more intense effect of reduced access to sanitation in municipalities with the worst mortality and morbidity indicators. In most models, this theory has been rejected

The demographic and epidemiological transition process caused by a declining in birth rates and in mortality, also changes occurred in morbidity and mortality is represented by the increasing of the aging population and the raising of chronic diseases. These diseases are characterized by multiple etiologies, risk factors, long latency period, a prolonged evolution, non-infectious origin and it has association with functional impairment and disability. Thus, elderly with chronic non-communicable disease has priority because they belong to a vulnerable group to get affection of comorbidities in aging, with increased demand and spending on health services. This study is aimed to analyse the understanding of elderly people with chronic non comunicable disease in the medium complexity service as a contribution to the improvement of health care in the city of Natal / RN. This is a descriptive and exploratory study with a quantitative approach, carried out at the Specialized Center for Elderly Health Care and at the Pescadores Hospital. The population was composed of 4,180 persons with a sample of 124 elderly aged above 60 years, attended in these medium complexity services. The instrument, a structured form, adapted from a questionnaire for monitoring risk and protective factors for chronic disease of the Ministry of Health. To collect data was was used the interview form containing demographic data, habits, health status and health care services. The results were processed using the Statistical Package for Social Science, version 18.0, analyzed by simple statistics. It was found that most seniors were female, predominantly between 70 and 74 years old, married, with a brown skin tone and Catholic religion, more than half had incomplete basic education, family income between one to two minimum wages and living with their families. Regarding the interviewers lifestyle, 94.4%, of them ate chicken and 97.6%, fruits, it was observed a reduction in smoking, alcoholism habits and physical activity according to the increasing age, 58.1 and 18.5% had insomnia18,5 % used sleeping pills. The elderly (51.6%) reported using services in times of sickness, seeking primary care at first (30.6%), 52% did not receive referral and was looking for free demand (38.7%). The most reported morbidity was hypertension, followed by musculoskeletal disorders. Regarding the difficulties in seeking health services, the delay in treatment and the waiting line were the most cited by the elderly. Almost all of them reported no activities to promote health in these services and those who received individual counseling on chronic diseases. Almost always, the health professionals who care of them, were mostly doctors followed by nurses. Based on the results presented, it is considered that the health services of medium complexity must undergone a more continuous dialogue with other attention level and focus on actions of health promotion and prevention. It is also recommended the necessity for qualified professionals to delivery health care to elderly and the implementation of protocols by a multidisciplinary health team, intending to provide better and continous care for the elderly with chronic diseases. The healthcare professionals who served them, were mostly physicians, followed by nurses. Through the results presented, it is considered that the medium complexity healthcare services need to perform a more continuous dialogue with the other levels of attention focusing attention to the health promotion and prevention actions. It is also recommended the necessity for qualified professionals to delivery healthcare for the elderly, in addition, a protocol implementation for the multidisciplinary health care team, to provide better care, and also the care continuity to elderly with chronic diseases

Measures of mortality represent one of the most important indicators of health conditions. For comprising the larger rate of deaths, the study of mortality in the elderly population is regarded as essential to understand the health situation. In this sense, the present study aims to analyze the mortality profile of the population from 60 to 69 (young elders) and older than 80 years old (oldest old) in the Rio Grande do Norte state (Brazil) in the period 2001 to 2011, and to identify the association with contextual factors and variables about the quality of the Mortality Information System (SIM). For this purpose, Mortality Proportional (MP) was calculated for the state and Specific Mortality Rate by Age (CMId) , according to chapters of ICD- 10, to the municipalities of Rio Grande do Norte , through data from the Mortality Information System (SIM) and the Brazilian Institute of Geography and Statistics (IGBE). In order to identify groups of municipalities with similar mortality profiles, Nonhierarchical Clustering K-means method was applied and the Factor Analysis by the Principal Components Analysis was resort to reduce contextual variables. The spatial distribution of these groups and the factors were visualized using the Spatial Analysis Areas technique. During the period investigated, 21,813 younger elders deaths were recorded , with a predominance of deaths from circulatory diseases (32.75%) and neoplasms (22.9 %) . Among the oldest old, 50,637 deaths were observed, which 35.26% occurred because of cardiovascular diseases and 17.27% of ill-defined causes. Clustering Analysis produced three clusters to the two age groups and Factor Analysis reduced the contextual variables into three factors, also the sum of the factor scores was considered. Among the younger elders, the groups are called misinformation profile, development profile and development paradox, which showed a statistically significant association with education and poverty and extreme poverty factors, factorial sum and the variable related to underreporting of deaths. Misinformation profile remained in the oldest old group, accompanied by the epidemiological transition profile and the epidemiological paradox, that were statistically associated with the development and health factor, as well as with the variables that indicate the SIM quality: proportion of blank fields about the schooling and underreporting. It proposed that the mortality profiles of the younger elders and oldest old differ on the importance of the basic causes and that are influenced by different contextual aspects , observing that 60 to 69 years group is more affected by such aspects. Health inequalities can be reduced by measures aimed to improve levels of education and poverty, especially in younger elders, and by optimizing the use of health services, which is more associated to the oldest old health situation. Furthermore, it is important to improve the quality of information for the two age groups
