Age and Ageing is now inviting papers on healthcare improvement for older people. In this article we outline the nature and scope of healthcare improvement and reference improvement models and the tools and methods of improvement science. We emphasise the issues of sustainability, including scale and spread; evaluation – including associated ethical consideration and the involvement of patients and the public in healthcare improvement and associated research. Throughout we refer to resources the authors have found useful in their own work, and provide a bibliography of sources and web-links which will provide essential guidance and support for potential contributors to this new category of submission to Age and Ageing.

As people age they are at increased risk of cardiovascular disease, the leading cause of mortality and morbidity worldwide. Understanding cardiovascular ageing is essential to preserving healthy ageing and preventing serious health outcomes. This collection of papers published in Age and Ageing since 2011 cover key themes in cardiovascular ageing, with a separate collection on stroke and atrial fibrillation planned. Treating high blood pressure remains important as people age and reduces strokes and heart attacks. That said, a more personalised approach to blood pressure may be even more important as people age to lower blood pressure to tight targets where appropriate but avoid overtreatment in vulnerable groups. As people age, more people experience blood pressure drops on standing (orthostatic hypotension), particularly as they become frail. This can predispose them to falls. The papers in this collection provide an insight into blood pressure and orthostatic hypotension. They highlight areas for further research to understand blood pressure changes and management in the ageing population. Inpatient clinical care of older people with heart attacks differs from younger people in UK national audit data. People aged over 80 had improved outcomes in survival after heart attack over time, but had lower rates of specialist input from cardiology compared with younger people. This may partly reflect different clinical presentations, with heart attacks occurring in the context of other health conditions, frailty and multimorbidity. The care and outcomes of acute and chronic cardiovascular disease are impacted by the frailty and health status of an individual at baseline. The research included in this collection reinforces the wide variations in the ageing population and the necessity to focus on the individual needs and priorities, and provide a person-centred multidisciplinary approach to care.

The authors assessed the utility and cost-effectiveness of using a World Wide Web-based questionnaire in a large prospective cohort study, the Black Women's Health Study (BWHS). In 1995, 59,000 African-American women were recruited into the BWHS through a paper questionnaire. Follow-up paper questionnaires have been mailed every 2 years since then. During the 2003, 2005, and 2007 questionnaire cycles, participants were given the option of completing a Web-based questionnaire. The cost of developing and processing a returned paper questionnaire was 4 times that of a returned Web questionnaire, primarily because of return postage costs and greater processing time for paper questionnaires. The proportion of respondents who completed a Web questionnaire doubled from 2003 to 2007, from 10.1% to 19.9%, but the characteristics of those completing the Web questionnaire remained the same. Web response was greatest at younger ages (20.9% of those aged <30 years) and declined with age to 3.6% among women aged 60 years or more. Web questionnaires were filled out more completely than paper questionnaires, regardless of the sensitivity of a question. The use of a Web questionnaire in the BWHS resulted in cost savings and more complete responses. Although there are advantages to using a Web questionnaire, the use of multiple means of soliciting questionnaire responses is still needed. [ABSTRACT FROM PUBLISHER]

Background Older people are often explicitly or implicitly excluded from research, in particular clinical trials. This means that study findings may not be applicable to them, or that older people may not be offered treatments due to an absence of evidence. Aims The aim of this work was to develop recommendations to guide all research relevant to older people. Methods A diverse stakeholder group identified barriers and solutions to including older people in research. In parallel, a rapid literature review of published papers was undertaken to identify existing papers on the inclusion of older people in research. The findings were synthesised and mapped onto a socio-ecological model. From the synthesis we identified themes that were developed into initial recommendations that were iteratively refined with the stakeholder group. Results A range of individual, interpersonal, organisational, community and policy factors impact on the inclusion of older people in research. A total of 14 recommendations were developed such as removing upper age limits and comorbidity exclusions, involving older people, advocates and health and social care professionals with expertise in ageing in designing the research, and considering flexible or alternative approaches to data collection to maximise opportunities for participation. We also developed four questions that may guide those developing, reviewing and funding research that is inclusive of older people. Conclusion Our recommendations provide up to date, practical advice on ways to improve the inclusion of older people in health and care research. [ABSTRACT FROM AUTHOR]

With an increase in the ageing population, there is a rise in the burden of cardiovascular disease. Age and Ageing have compiled collections of their key cardiovascular themed papers. The first Age and Ageing Cardiovascular Collection focussed on blood pressure, coronary heart disease and heart failure. In this second collection, publications since 2011 were selected with emphasis on atrial fibrillation, transient ischaemic attack (TIA) and stroke. The prevalence of TIA and stroke increases as people get older. In this commentary we summarise studies published in Age and Ageing that bring to the fore the need for a multidisciplinary, person-centred approach to care, conscientious identification of risk factors and their management and prevention strategies, which will inform policy ultimately reducing the burden of cost placed by stroke care on healthcare financing.

Language development is an important facet of early life. Deaf children may have exposure to various languages and communication modalities, including spoken and visual. Previous research has documented the rate of growth of English skills among young deaf children, but no studies have investigated the rate of ASL acquisition. The current paper examines young deaf children's acquisition of ASL skills, the rate of growth over time, and factors impacting levels and growth rates. Seventy-three children ages birth to 5 were rated three times using the Visual Communication and Sign Language Checklist and given a scaled score at each rating. An average monthly gain score was calculated for each participant. The presence of a deaf parent, use of ASL at home, use of cochlear implant(s), whether the child was born deaf, and age of initial diagnosis were analyzed for their impact on the level of ASL skill and rate of growth. Results indicated that the use of ASL in the home has a significant positive effect on deaf children's ASL skill level. Additionally, children with lower initial ratings showed higher rates of growth than those with higher initial ratings, especially among school-aged children. The paper discusses implications and directions for future studies. [ABSTRACT FROM AUTHOR]

Background Lesbian, gay, bisexual, trans and intersex (LGBTI) people experience significant health inequalities. Located within a European Commission funded pilot project, this paper presents a review of the health inequalities faced by LGBTI people and the barriers health professionals encounter when providing care. Methods A narrative synthesis of 57 papers including systematic reviews, narrative reviews, meta-analyses and primary research. Literature was searched in Cochrane, Campbell Collaboration, Web of Science, CINAHL, PsychINFO and Medline. The review was undertaken to promote understanding of the causes and range of inequalities, as well as how to reduce inequalities. Results LGBTI people are more likely to experience health inequalities due to heteronormativity or heterosexism, minority stress, experiences of victimization and discrimination, compounded by stigma. Inequalities pertaining to LGBTI health(care) vary depending on gender, age, income and disability as well as between LGBTI groupings. Gaps in the literature remain around how these factors intersect to influence health, with further large-scale research needed particularly regarding trans and intersex people. Conclusion Health inequalities can be addressed via changes in policy, research and in practice through health services that accommodate the needs of LGBTI people. With improved training to address gaps in their knowledge of LGBTI health and healthcare, health professionals should work in collaboration with LGBTI people to address a range of barriers that prevent access to care. Through structural change combined with increased knowledge and understanding, services can potentially become more inclusive and equally accessible to all. [ABSTRACT FROM AUTHOR]

Objectives This paper models cognitive aging, across mid and late life, and estimates birth cohort and sex differences in both initial levels and aging trajectories over time in a sample with multiple cohorts and a wide span of ages. Methods The data used in this study came from the first 9 waves of the English Longitudinal Study of Ageing, spanning 2002–2019. There were n = 76,014 observations (proportion male 45%). Dependent measures were verbal fluency, immediate recall, delayed recall, and orientation. Data were modeled using a Bayesian logistic growth curve model. Results Cognitive aging was substantial in 3 of the 4 variables examined. For verbal fluency and immediate recall, males and females could expect to lose about 30% of their initial ability between the ages of 52 and 89. Delayed recall showed a steeper decline, with males losing 40% and females losing 50% of their delayed recall ability between ages 52 and 89 (although females had a higher initial level of delayed recall). Orientation alone was not particularly affected by aging, with less than a 10% change for either males or females. Furthermore, we found cohort effects for initial ability level, with particularly steep increases for cohorts born between approximately 1930 and 1950. Discussion These cohort effects generally favored later-born cohorts. Implications and future directions are discussed. [ABSTRACT FROM AUTHOR]

Background and Objectives Chronological age is invariably used as a categorizing tool for spaces, collections, and programs in public libraries. With age-based conceptions of human experience in library practice, education, and scholarship primarily focused on those under the age 18, little is known how age-based classifications are implemented in public libraries, and with what impacts, for older library patrons. Research Design and Methods Stemming from a larger project that seeks to bring attention to the ways in which public libraries engage with community-dwelling older adults, this paper explores 51 older patrons' perspectives on the numbers and language (e.g. 55+, older adult, seniors, adult) assigned to older adults in library programs and which label best (or least) suits their sense of identity and, in turn, what language encourages or deters their engagement with library programs. Results Findings illustrate that age-based language describing older adult library programs is often at odds with patrons' perceptions of how library programming relevant to them ought to be labeled. Common to all participants was a clear dislike for the term "elderly." While most participants preferred "older adult" to "senior," others voiced no preference, as long as they felt heard and valued. Many participants linked the use of language used to describe library programs to being excluded from and treated differently from other (younger) library patrons. Discussion and Implications The language used to group and describe different library populations directly shapes feelings of belonging (or exclusion) in library programs. Insights from this research contribute to our evolving understandings of the ways in which language connected to age can shape one's sense of identity. Results also serve to cultivate a more sensitive and critical approach to the question of age within library science, and, by extension, the experiences of older adults who frequent the library.

Background This paper concerns the spatial determinants of the first two waves of COVID-19 at the neighbourhood level. Methods Using data for the first and second waves of COVID-19 at the neighbourhood level in Barcelona, we analyse whether local characteristics acted in the same way during the two waves and identify typologies of areas depending on such determinants. Univariate and bivariate local Moran's I and count data models are used. Results Some structural effects at the neighbourhood level consistently either boost (e.g. population density) or reduce (e.g. income) COVID-19 cases. Other effects differ between the two waves (i.e. age composition, schools and transport infrastructures). Conclusions Since certain characteristics influenced the virus diffusion in opposite ways between the two pandemic waves, territorial heterogeneity alone is insufficient to explain COVID-19 outbreaks—individual behaviour also needs to be factored in. Consequently, both econometric and spatial analysis techniques are recommended for tracking the spatiotemporal spread of this disease and for monitoring the effectiveness of policy measures across heterogeneous neighbourhoods.

Background Increasing numbers of children have been forced to flee and seek asylum in high-income countries. Current research indicates that focussing on resilience and protective factors is an important long-term goal for positive mental health and psychological functioning of refugee children. Methods We performed a systematic review of quantitative literature regarding psychological and contextual factors that contribute to resilience in refugee children residing in high-income countries. Our procedure followed guidelines from the Centre for Reviews and Dissemination. Results We identified a number of protective factors as related to positive outcomes. They are drawn from several ecological domains and include age, self-esteem, maintenance of cultural identity, social support, belonging and safety and innovative social care services. A key overarching point reported by the studies we reviewed was that for refugee settlement specific policies and approaches to be beneficial, they were required to be embedded within a positive socially inclusive society. We also identified several limitations across the reported studies. Conclusion The factors we identified would assist clinicians to adopt a resilience-focussed approach. However, a continued pre-occupation with psychopathology was evident across the studies, which we argue as holding back the development of resilience-focussed approaches. [ABSTRACT FROM AUTHOR]

Background Schizophrenia is a chronic disease associated with significant and long-lasting effects on health, and it is also a social and financial burden, not only for patients but also for families, other caregivers, and the wider society. It is essential to conduct the assessment of indirect costs, to understand all the effects of the disease on society. Our aim is to gain a better understanding of the indirect costs of schizophrenia in Europe. Methods We conducted a comprehensive systematic literature review covering EMBASE, Medline, and PsycINFO as well as reviewing Health Technology Assessment databases from different countries. We used a qualitative research synthesis for presenting information, as most of the studies were methodologically diverse, a quantitative analysis would have been impractical. Results Indirect cost adjusted to inflation ranged vastly between studies included in the review from 119 Euros to 62, 034 Euros annually. The average proportion of indirect costs of total costs was 44%. Studies highlighted important cost drivers as age, gender, and disease severity, explaining the variation in costs between treatment and patient groups. Conclusions Regardless of the methodological heterogeneity of the reviewed studies, there was an agreement about the significance of indirect costs of schizophrenia on the society. Considering the relatively high prevalence of schizophrenia in Europe, a need for more cost of illness studies especially from Central Eastern and Southern Europe is suggested.

Background and Objectives Ageism is oftentimes sugarcoated within humor. Paper birthday cards are 1 delivery approach in which ageist messages are perpetuated and reinforced through humor. Research Design and Methods A convenience sample of birthday cards (k = 227), all indicating a decade of age, were acquired from 7 national retail stores in Colorado Springs, CO. The decades sampled ranged from 21 to 100. With a predeveloped codebook, 3 raters coded the decade birthday cards on various variables, including age group, ageist tone, and humor. Results Birthday cards intended for age 30–60 contained significantly more ageist messages compared to cards intended for age 21 and age 70–100, which did not show a significant difference from each other. Additionally, birthday cards with humor showed more ageist messages than cards without humor. Characteristics of decade birthday cards were also explored. Discussion and Implications Consumers need to learn to evaluate these ageist messages in birthday cards to reduce the perpetuation of damaging stereotypes. [ABSTRACT FROM AUTHOR]

Aims Cardiovascular magnetic resonance parametric mapping enables non-invasive quantitative myocardial tissue characterization. Human myocardium has normal ranges of T1 and T2 values, deviation from which may indicate disease or change in physiology. Normal myocardial T1 and T2 values are affected by biological sex. Consequently, normal ranges created with insufficient numbers of each sex may result in sampling biases, misclassification of healthy values vs. disease, and even misdiagnoses. In this study, we investigated the impact of using male normal ranges for classifying female cases as normal or abnormal (and vice versa). Methods and results One hundred and forty-two healthy volunteers (male and female) were scanned on two Siemens 3T MR systems, providing averaged global myocardial T1 and T2 values on a per-subject basis. The Monte Carlo method was used to generate simulated normal ranges from these values to estimate the statistical accuracy of classifying healthy female or male cases correctly as 'normal' when using sex-specific vs. mixed-sex normal ranges. The normal male and female T1- and T2-mapping values were significantly different by sex, after adjusting for age and heart rate. Conclusion Using 15 healthy volunteers who are not sex specific to establish a normal range resulted in a typical misclassification of up to 36% of healthy females and 37% of healthy males as having abnormal T1 values and up to 16% of healthy females and 12% of healthy males as having abnormal T2 values. This paper highlights the potential adverse impact on diagnostic accuracy that can occur when local normal ranges contain insufficient numbers of both sexes. Sex-specific reference ranges should thus be routinely adopted in clinical practice. [ABSTRACT FROM AUTHOR]

Objectives Little is known about the length of working life, even though it is a key indicator for policy-makers. In this paper, we study how the length of working life at age 50 has developed in the United States from a cohort perspective. Methods We use a large longitudinal sample of U.S. Social Security register data that covers close to 1.7 million individuals of the cohorts born from 1920 to 1965. For all of these cohorts, we study the employment trajectories and working life expectancy (WLE) at age 50 by gender and nativity (native-born/foreign-born). For the cohorts with employment trajectories that are only incompletely observed, we borrow information from older cohorts to predict their WLE. Results The length of working life has been increasing for the native-born males and females, and the younger cohorts worked longer than the older cohorts. However, WLE might soon peak, and then stall. The gap in WLE between the native-born and the foreign-born has increased over time, although latter group might be able to catch up in the coming years. Discussion Our findings show that studying employment from a cohort perspective reveals crucial information about patterns of working life. The future development of the length of working life should be a major concern for policy-makers. [ABSTRACT FROM AUTHOR]

Introduction the COVID-19 pandemic poses a high risk to older people. The aim of this article is to provide a rapid overview of the COVID-19 literature, with a specific focus on older adults. We frame our findings within an overview of the disease and have also evaluated the inclusion of older people within forthcoming clinical trials. Methods we searched PubMed and bioRxiv/medRxiv to identify English language papers describing the testing, treatment and prognosis of COVID-19. PubMed and bioRxiv/medRxiv searches took place on 20 and 24 March 2020, respectively. Results screening of over 1,100 peer-reviewed and pre-print papers yielded n  = 22 on COVID-19 testing, n  = 15 on treatment and n  = 13 on prognosis. Viral polymerase chain reaction (PCR) and serology are the mainstays of testing, but a positive diagnosis may be increasingly supported by radiological findings. The current evidence for the effectiveness of antiviral, corticosteroid and immunotherapies is inconclusive, although trial data are largely based on younger people. In addition to age, male gender and comorbidities, specific laboratory and radiology findings are important prognostic factors. Evidence suggests that social distancing policies could have important negative consequences, particularly if in place for an extended period. Conclusion given the established association between increasing age and poor prognosis in COVID-19, we anticipate that this rapid review of the current and emergent evidence might form a basis on which future work can be established. Exclusion of older people, particularly those with comorbidities, from clinical trials is well recognised and is potentially being perpetuated in the field of current COVID-19 research.

This paper is written from the perspective of patients who have been diagnosed with takotsubo syndrome. It seeks to understand why these patients may feel dissatisfied with the care they receive. We consider four factors: (a) takotsubo syndrome is a relatively new condition and the knowledge base about treatment is limited and not widely disseminated among clinicians; (b) the age and gender profile of the patient group; (c) the implications of the categorisation of takotsubo syndrome as 'broken heart syndrome' and the over-emphasis of it as a 'psychosomatic' condition; (d) concern that patients with takotsubo syndrome might be labelled as over-emotional, especially if they do not recover quickly. We argue that these factors contribute to patients with takotsubo syndrome feeling poorly served. [ABSTRACT FROM AUTHOR]

In this paper, we analyse the metallicity structure of the Magellanic Clouds using parameters derived from the Gaia Data Release 3 (DR3) low-resolution XP (for Blue/Red Photometer) spectra, astrometry, and photometry. We find that the qualitative behaviour of the radial metallicity gradients in the Large Magellanic Cloud (LMC) and Small Magellanic Cloud (SMC) is quite similar, with both of them having a metallicity plateau at intermediate radii and a second at larger radii. The LMC has a first metallicity plateau at [M/H] ≈ −0.8 for 3–7°, while the SMC has one at [M/H] ≈ −1.1 for 3–5°. The outer LMC periphery has a fairly constant metallicity of [M/H] ≈ −1.0 (10–18°), while the outer SMC periphery has a value of [M/H] ≈ −1.3 (6–10°). The sharp drop in metallicity in the LMC at ∼8° and the marked difference in age distributions in these two regions suggest that there were two important evolutionary phases in the LMC. In addition, we find that the Magellanic periphery substructures, likely Magellanic debris, are mostly dominated by LMC material stripped off in old interactions with the SMC. This presents a new picture in contrast with the popular belief that the debris around the clouds had been mostly stripped off from the SMC due to having a lower mass. We perform a detailed analysis for each known substructure and identify its potential origin based on metallicities and motions with respect to each galaxy. [ABSTRACT FROM AUTHOR]

Background and Objectives Given the increasing academic interest in older migrants, this study aims at examining the likelihood of establishing contact and cooperation in a survey among first-generation migrants in Germany, comparing migrants of age 50 and older with younger migrants (aged 16–49). Research Design and Methods We analyze data from the Migrants' Welfare State Attitudes (MIFARE) study collected in Germany, which contains information about first-generation migrants from 9 different origin groups living in private households. Potential survey participants were contacted via mail and invited to participate in a paper- or online-based survey. In addition, an incentive experiment was implemented and age-dependent response rates were analyzed. Using logistic regression analyses, we compare older and younger migrants with regard to their likelihood of contact, cooperation, reaction to incentives, and mode choice. Results Within the MIFARE study, older migrants are more likely to be contacted than younger ones. Older migrants are also more likely to cooperate in survey research than younger migrants. Both groups respond equally positively to the use of unconditional incentives. Lastly, older migrants show a strong preference to fill out the questionnaire on paper, rather than online. Discussion and Implications Older first-generation migrants living in private households are easier to contact and are more likely to cooperate in survey research than younger first-generation migrants. Offering unconditional incentives and surveys on paper are likely to increase response rates among older migrants. [ABSTRACT FROM AUTHOR]

In high-income countries that were first to roll out coronavirus disease 2019 (COVID-19) vaccines, older adults have thus far usually been prioritized for these vaccines over younger adults. Age-based priority primarily resulted from interpreting evidence available at the time, which indicated that vaccinating the elderly first would minimize COVID-19 deaths and hospitalizations. The World Health Organization counsels a similar approach for all countries. This paper argues that some low- and middle-income countries that are short of COVID-19 vaccine doses might be justified in revising this approach and instead prioritizing certain younger persons when allocating current vaccines or future variant-specific vaccines.

Background Previous research has suggested an ethnic association of Heck's disease with a prominent genetic and familial inheritance pattern, but no systematic review has been reported, which has collected all the evidence in one paper. The aim was estimation of the updated age estimates and gender predilection of this disease and also questioning its proposed link to ethnic and geographical factors. Methods Heck's disease from 1966 until present are tabulated, including various descriptive characteristics. After removal of duplicates and adhering to all the inclusion criteria, we shortlisted 95 case reports. The quality assessment of all included studies has been done following STROBE (STrengthening the Reporting of OBservational studies in Epidemiology) guidelines. Results We found an age range of 3–92 years (mean: 23.1 years) with a male to female ratio of 3:4. Geographical distribution revealed one of the main findings of this study, which was an increased incidence of Heck's disease in the European region. Conclusions As already observed and established, there is a much greater prevalence of this disease in the indigenous populations of the world and more research should be encouraged to understand the correct transmission and pattern of spread of this disease.

A letter to the editor is presented in response to the article "Language-group mortality differentials in Finland in 1988-2004: assessment of the contribution of cause of death, sex and age," by P. Sipilä and P. Martikainen in the 2009 issue.

Methods for calculating health indicators profoundly influence understanding of and action on population health and inequities. Age-standardization can be useful and is commonly applied to account for differences in age structures when comparing health indicators across groups. Age-standardized rates have well-acknowledged limitations, including that they are relative indices for comparison, and not accurate measures of actual rates where the age structures of groups diverge. This paper explores these limitations, and demonstrates alternative approaches through a case study quantifying mortality rates within the Aboriginal and Torres Strait Islander (Indigenous) population of Australia and inequities compared with the non-Indigenous population, over 2001-16. Applying the Australian Standard Population, the Aboriginal and Torres Strait Islander age-standardized mortality rate was more than double the crude mortality rate in 2001 and 2016, inflated through high weighting of older age groups. Despite divergent population age structures, age-standardized mortality rates remain a key policy metric for measuring progress in reducing Indigenous-non-Indigenous inequities in Australia. Focusing on outcomes age-standardized to the total population can obscure inequities, and denies Aboriginal and Torres Strait Islander peoples and communities valid, actionable information about their health and well-being. Age-specific statistics convey the true magnitude of health risks and highlight high-risk subgroups. When requiring standardization, standardizing to a population-specific standard (here, an Indigenous standard) generates metrics centred around and reflective of reality for the population of focus, supporting communities' self-determination to identify priorities and informing resource allocation and service delivery. The principles outlined here apply across populations, including Indigenous and other populations internationally. [ABSTRACT FROM AUTHOR]

The containment of infectious diseases is most successful when at-risk populations have a high level of relevant health literacy (HL). To achieve this both literacy needs and patterns of knowledge sharing must be understood within the context of the disease being studied. It is also important to understand these processes from both offline (HL) and online (eHL) perspectives and amongst demographics with access to different types of information and social capital, and who have different levels of vulnerability. This paper discusses the insights gained over a series of 30 interviews with the UK residents aged either 19 − 30 years of age or older than 70 years—focussing on how they seek, understand, evaluate and convey information about COVID-19 during the current pandemic. Using thematic analysis, we identified themes around motivations to seek information, the information journey, digital choice and engagement, dilemmas and challenges of managing and appraising information, and sharing information. There was little difference in the eHL between the two age groups who both had high levels of education and were sophisticated digital citizens. The COVID-19 pandemic highlights three dominant processes in managing complex and uncertain information: some individuals may suffer from information fatigue but there was no evidence of any impact on their behaviours; others seek and share information across many networks; and there were strikingly high levels of distrust leading to complex processes of meaning-making demanding critical health literacy skills.

Epidemiologists commonly use an adjusted hazard ratio or incidence density ratio, or a standardized mortality ratio, to measure a difference in all-cause mortality rates. They seldom translate it into an age-, time-, or probability-based measure that would be easier to communicate and to relate to. Several articles have shown how to translate from a standardized mortality ratio or hazard ratio to a longevity difference, a difference in actuarial ages, or a probability of being outlived. In this paper, we describe the settings where these translations are and are not appropriate and provide some of the heuristics behind the formulae. The tools that yield differences in "effective age" and in longevity are applicable when both 1) the mortality rate ratio (hazard ratio) is constant over age and 2) the rates themselves are log-linear in age. The "probability/odds of being outlived" metric is applicable whenever the first condition holds, and thus it provides no direct information on the magnitude of the effective age/longevity difference.

The coronavirus disease 19 (COVID-19) pandemic is a disaster that has impacted lives globally. The purpose of this paper is to understand the linkage between COVID-19 and its impact on mental health. To reach this aim, we reviewed the literature on COVID-19 and mental conditions. Based on the literature, we identified COVID-19 as an unexpected, large-scale event that disrupted communities and caused death, destruction and trauma which upended normal existence. For mental conditions, effects of the pandemic are likely to manifest in different ways: development of symptoms in previously healthy individuals, new episodes in those with predisposition to mental disorders and development of symptoms that do not meet diagnostic criteria. The level of mental health problems varies depending on the stage of the pandemic, country, population groups and types of conditions. This also applies to the level of suicide, although suicides do not seem to have increased during the pandemic. Yet, we identified a net of factors contributing to mental conditions, in general. These factors include demographic factors (e.g. female gender, younger and older age), social factors (e.g. economically disadvantaged), mental factors (e.g. pre-existing mental conditions) and relationship factors (e.g. stressful relationship, lack of relationships). Additionally, we identified COVID-19-specific factors such as threat to own life and threat to life of loved ones, containment measures and interruption of services and social life. We further explored potentially additional suicide-related risk factors. Regardless of differences, health care and psychosocial systems were in many countries not prepared to respond to a viral disaster. Viral disaster requires that responses not only include direct care but also responses to populations that may need support due to known determinants of mental health. [ABSTRACT FROM AUTHOR]

In a 1989 paper, Marchbanks et al. (Am J Epidemiol. 1989; 130(2):259-267) noted inconsistent definitions of infertility across research and clinical practice and examined differences in prevalence estimates across definitions. Since their study, there have been substantial changes in society, technology, and clinical practice related to female reproductive health. In response, we revisited the original paper using data from a recent study among reproductive-aged women. Internal comparisons across various definitions of infertility were made by assessing how many and which women were classified as infertile, their age at infertility, and the probability of spontaneous pregnancy after infertility. Results were also compared with Marchbanks et al. Black women were more likely to be classified as infertile than white women based on the definition "12 months of unprotected intercourse" (40.1% vs. 33.7%) but less likely by "12 months of attempting pregnancy" (14.3% vs. 21.8%) and "visiting a doctor for help getting pregnant" (8.4% vs. 19.7%). After unprotected intercourse for 12 months, 36.1% of women who were attempting pregnancy spontaneously conceived by 6 months compared with 13.5%of women who were not attempting pregnancy. While our results for most infertility definitions were similar to those of Marchbanks et al., prevalence estimates continued to differ across demographic groups by definition.

For all health conditions, reliable age-disaggregated data are vital for both epidemiological analysis and monitoring the relative prioritization of different age groups in policy responses. This is especially essential in the case of Coronavirus Disease-2019 (COVID-19), given the strong association between age and case fatality. This paper assesses the availability and quality of age-based data on reported COVID-19 cases and deaths for low- and middle-income countries. It finds that the availability of reliable data which permit specific analyses of older people is largely absent. The paper explores the potential of excess mortality estimates as an alternative metric of the pandemic's effects on older populations. Notwithstanding some technical challenges, this may offer a better approach, especially in countries where cause of death data are unreliable. [ABSTRACT FROM AUTHOR]

Background Prevalence of overweight and obesity in Germany is increasing. High body weight can affect children's growth and development. This paper aimed to determine the association between body mass index (BMI) and visual impairment among preschool children and explore the potential role of obesity in predicting visual developmental disorder. Methods Six consecutive years of data from the School Entry Examination were collected for all preschool children aged from 4 to 6 years residing in Rhine-Neckar County and the City of Heidelberg, Germany from 2013 to 2018. Univariate and multivariate regression were used to analyze the complete data, multiple imputation was used to deal with missing data. Results Among the group with an immigrant background, children with obesity [OR = 1.20, 99% (1.02–1.42)] were more likely to have visual impairment compared to those with normal body weight (P  <   0.01) after adjusting for survey year, age, and gender of children, education and occupation of parents, screen time-frequency, whether a television was in their bedroom, and quality of preschool outdoor environment. Conclusion There were significant associations between obesity and visual impairment among German preschool children with immigrant backgrounds. Strategies to support vulnerable groups were needed across all regional schools. [ABSTRACT FROM AUTHOR]

The matter of disclosure of donor conception to donor offspring is a very contentious issue. A frequently mentioned argument is that disclosure is in the best interest of the child. The objectives of this paper are 2-fold: first, to find out whether there are any measureable, stable differences in the psychological well-being of donor offspring who are informed of the mode of their conception compared to those who are not, and second, to find out what is being done with the evidence. We found that there exists no empirical evidence of differences in psychological well-being of donor offspring in disclosing or nondisclosing families. Regarding the age of disclosure, the findings are inconclusive. Some studies indicate no difference and some show slight positive effects of early disclosure. We also found that authors tend to ignore their own findings when formulating recommendations and that the recommendations are based on implicit moral premises. We conclude that disclosure, and directive counseling towards disclosure, cannot be justified by the welfare of the donor offspring. [ABSTRACT FROM AUTHOR]

This paper reports an environmental analysis of 41 uniformly selected stripped-envelope supernovae (SESNe) based on deep ultraviolet–optical images acquired by the Hubble Space Telescope. Young stellar populations are detected in most SN environments and their ages are derived with a hierarchical Bayesian approach. The age distributions are indistinguishable between Type IIb and Type Ib, while that for Type Ic is systematically younger. This suggests that the Type Ic SN progenitors are more massive, while the Type IIb and Type Ib SNe have very similar progenitor masses. Our result supports a hybrid envelope-stripping mechanism, in which the hydrogen envelopes of the SESN progenitors are stripped via a mass-insensitive process (e.g. binary interaction), while the helium envelopes are stripped via a mass-sensitive process (e.g. stellar wind of the post-binary interaction progenitor). We also provide progenitor constraints for three Type Ibn SNe and two broad-lined Type Ic SNe. All these results demonstrate the importance of the very diverse mass-loss processes in the origins of SESNe. [ABSTRACT FROM AUTHOR]

A long-standing problem when deriving the physical properties of stellar populations is the degeneracy between age, reddening, and metallicity. When a single metallicity is used for all the star clusters in a galaxy, this degeneracy can result in 'catastrophic' errors for old globular clusters. Typically, approximately 10–20 per cent of all clusters detected in spiral galaxies can have ages that are incorrect by a factor of 10 or more. In this paper, we present a pilot study for four galaxies (NGC 628, NGC 1433, NGC 1365, and NGC 3351) from the PHANGS-HST survey. We describe methods to correct the age-dating for old globular clusters, by first identifying candidates using their colours, and then reassigning ages and reddening based on a lower metallicity solution. We find that young 'Interlopers' can be identified from their Hα flux. CO (2-1) intensity or the presence of dust can also be used, but our tests show that they do not work as well. Improvements in the success fraction are possible at the ≈15 per cent level (reducing the fraction of catastrophic age-estimates from between 13 and 21 per cent, to between 3  and 8 per cent). A large fraction of the incorrectly age-dated globular clusters are systematically given ages around 100 Myr, polluting the younger populations as well. Incorrectly age-dated globular clusters significantly impact the observed cluster age distribution in NGC 628, which affects the physical interpretation of cluster disruption in this galaxy. For NGC 1365, we also demonstrate how to fix a second major age-dating problem, where very dusty young clusters with E (B − V) > 1.5 mag are assigned old, globular-cluster like ages. Finally, we note the discovery of a dense population of ≈300 Myr clusters around the central region of NGC 1365 and discuss how this results naturally from the dynamics in a barred galaxy.

Background older patients aged ≥65 years constitute the majority of the National Emergency Laparotomy Audit (NELA) population. To better understand this group and inform future service changes, this paper aims to describe patient characteristics, outcomes and process measures across age cohorts and temporally in the 4-year period (2014–2017) since NELA was established. Methods patient-level data were populated from the NELA data set years 1–4 and linked with Office of National Statistics mortality data. Descriptive data were compared between groups delineated by age, NELA year and geriatrician review. Primary outcomes were 30- and 90-day mortality, length of stay (LOS) and discharge to care-home accommodation. Results in total, 93,415 NELA patients were included in the analysis. The median age was 67 years. Patients aged ≥65 years had higher 30-day (15.3 versus 4.9%, P  < 0.001) and 90-day mortality (20.4 versus 7.2%, P  < 0.001) rates, longer LOS (median 15.2 versus 11.3 days, P  < 0.001) and greater likelihood of discharge to care-home accommodation compared with younger patients (6.7 versus 1.9%, P  < 0.001). Mortality rate reduction over time was greater in older compared with younger patients. The proportion of older NELA patients seen by a geriatrician post-operatively increased over years 1–4 (8.5 to 16.5%, P  < 0.001). Post-operative geriatrician review was associated with reduced mortality (30-day odds ratio [OR] 0.38, confidence interval [CI] 0.35–0.42, P  < 0.001; 90-day OR 0.6, CI 0.56–0.65, P  < 0.001). Conclusions older NELA patients have poorer post-operative outcomes. The greatest reduction in mortality rates over time were observed in the oldest cohorts. This may be due to several interventions including increased perioperative geriatrician input. [ABSTRACT FROM AUTHOR]

Background Non-pharmaceutical interventions (NPIs) decrease COVID-19 transmission. Reliability and validity of adherence to NPIs in accordance with normalization process theory (NPT) in coherent and convenient social subgroups using reflective measurement model assessment has not been evaluated. Methods In February 2021, a sample of medical students and people with substance use disorders in treatment as coherent (based on continuous probability distribution) vs. convenient groups (based on convenience, not equal probability) composed of travellers and COVID-19 suspected persons from Split-Dalmatia County (SDC) (n  = 656) in the Mediterranean completed self-administered surveys. Partial least squares structural equation modelling (PLS-SEM) was used to measure reflective model assessment of adherence to NPIs according to NPT. Results PLS-SEM reflective model assessment provided two-group specific factors in inverse relationships which determined adherence to NPIs with excellent goodness-of-fit [ χ 2 = 1.292, df = 1; P  = 0.297, CFI = 1, TLI = 0.997, RMSEA = 0.011 (90% CI 0–0.105), RMSEA P  = 0.604, SRMR = 0.008, Hoelter CN (α = 0.05) = 2322.757]. Significant negative factors covariance estimate (−0.716) revealed an inverse relationship between first (adherence to NPIs and internal locus of control (LoC) (0.640)) and second factor; young adulthood age (≤25) and highest level of education (1362). As the first factor increased the second tended to decrease. LoC is expected potential mechanism by which sex (MLsex = −0.017, SE = 0.007, P  < 0.016) and belonging to coherent subgroups (MLgroup = −0.008, SE = 0.003, P  = 0.015) can produce indirect effect of adherence to NPIs. Conclusions Coherent subgroups had a more pronounced tendency toward integration of NPIs in everyday life. Group factors that facilitate the normalization were higher educated younger adults with a tendency toward external LoC. [ABSTRACT FROM AUTHOR]

Background Consumption of alcohol is a risk factor for non-communicable and infectious diseases, mental health problems, and can lead injuries and violence. The aim of this study was to evaluate the prevalence of alcohol-involved deaths among decedents who died of external causes and underwent autopsy in Lithuania. Methods Study includes age persons of any age (from 0 to 110 years) who died and were autopsied in Lithuania from 1 January 2017 to 31 December 2020. Data were obtained from the Lithuanian State Register of Deaths and Their Causes. Results Among external causes of death, the presence of alcohol was detected in 55.0% of cases. Male decedents had a significantly higher number of positive BAC level recorded, at 46.6%, compared with female decedents (32.1%; P  < 0.001). The highest incidence of deaths where the alcohol was detected in the deceased's blood was found when the decedent was listed as being in the victims of assault group (71.5%, 95% CI 65.4–77.2). However, the highest median BAC score was found for those in the accidents group (59.7%, 95% CI: 58.2–61.2, BAC 2.42 ‰, IQR 1.86). Conclusions The findings of this study suggest that alcohol use may be a contributing factor in a wide range of fatal incidents, including accidents, injuries, and cases of violent intent. Inequalities between males and females were identified, with a higher proportion of males with alcohol detected in blood at the time of death. [ABSTRACT FROM AUTHOR]

A joint spatio–temporal distribution model of mackerel (ages 3–10) was developed to investigate the age-based responses of mackerel to three environmental drivers: sea surface temperature (SST), mixed layer depth, and chlorophyll-a concentration during the summer months 2010–20 in the Nordic Seas. The study showed that SST was the most important variable amongst the ones tested and had the strongest impact on the distribution of the younger age classes (3–5), which had a narrower range of favourable SST and a stronger aversion to cold temperatures than older individuals. Consequently, the impact of SST differed regionally; in the polar front regions, SST explained up to 61% of the variability in the observed density of young individuals, where Arctic water masses likely acted as a barrier to these young individuals. That said, part of it could be confounded with the limited migration capability of young mackerels, which could not reach the furthest frontal regions. In warmer southern waters, the same environmental variables had less explanatory power for mackerel of all ages. Individuals in the south were likely not constrained by temperature and perhaps more influenced by other variables, such as food availability or ocean current (throughout their migration path), for which appropriate data are lacking. Moreover, the model showed that older mackerel were distributed more to the north and west, and their migration pattern changed when the 2013 year-class no longer migrated to the west compared to previous year-classes. Additionally, all-year classes started migrating more eastward from summer 2018. [ABSTRACT FROM AUTHOR]

Objective Spousal caregiving can have strong implications for health and wellbeing given the strain and burden associated with the role. Maintaining activity engagement is important for late-life health and wellbeing, and may be a possible contributing mechanism to caregiver health and wellbeing. This paper examined longitudinal changes in activity engagement and asks how spousal caregiving status and caregiver age related to longitudinal activity engagement in a sample of older adults. Method Data from four waves of the Health and Retirement study were used to model associations between periods of being a spousal caregiver, age, and engagement in physical, social, self-care, passive, and novel information processing activities over a 6-year period. Results Caregiving status was associated with declines in physical activity engagement over time. Older age was associated with fewer physical and more self-care and passive activities. Discussion Caregivers' declines in participation in physical activities may be an important indicator for preservation of health and management of caregiving stress. [ABSTRACT FROM AUTHOR]

This study examines the predictors of job satisfaction among public sector social workers in occupied Palestinian territories. Using a quantitative design, data were collected in summer of 2016 through a paper-based, self-administered questionnaire (N = 237). Using hierarchical multiple regression, the three models explained 15 percent to 32 percent of the variance in job satisfaction. In the final model, coefficient indicated that monthly income, contract work status, service orientation, and supervisory support are related to job satisfaction. Respondents with more children and lower salaries showed lower levels of job satisfaction. Respondents who are working as temporary contract workers, who have positive attitudes toward the social work profession, and who have positive attitudes toward supervisory support are more likely to be satisfied with their job. Implications for administrative practice and policy are presented. [ABSTRACT FROM AUTHOR]

Background Currently, 1 in 10 people diagnosed with dementia in Ireland are aged under 65, this is termed "Younger Onset Dementia" (YOD). Though small in numbers these figures (4000 people) are increasing, and important differences exist between people diagnosed with (PwYOD) and those diagnosed with later onset dementia (LOD). As dementia is normally associated with advancing age, clinicians are not always on the alert for its diagnosis in younger people. Diagnosing YOD can be especially challenging since presentation may be atypical and there is a lack of clinical ownership in this area. Methods A structured literature review was conducted to identify optimum models of diagnostic processes and pathways for PwYOD. Two research questions were addressed: (i) what models for the diagnosis of PwYOD exist nationally and internationally, and what evidence supports these and (ii) what are the differences between diagnostic processes and pathways for PwYOD compared with PwLOD. A systematic search strategy was devised to identify all relevant scientific papers. Key databases were used, supplemented by grey literature searches. A narrative synthesis approach was undertaken to assess the literature identified. Results Pathways and processes to the diagnosis of YOD are unclear and complex and compared with LOD, diagnosis takes more time. PwYOD are more likely to have multiple referrals to different specialists, have their memory and cognitive complaints misattributed to other factors such as depression and experience longer delays in obtaining a diagnosis. Conclusion Few evidence-based best-practice models or guidelines for the diagnosis of YOD exist internationally. Increased awareness of the signs and symptoms of YOD among all healthcare professionals is necessary. There is a need for improved linkages to be developed between Geriatric Medicine, Neurology, Psychiatry, and Primary Care services and in certain instances for suspected cases of YOD to be referred to neurology-led memory clinics.

The majority of people living with Alzheimer disease (AD) and related dementias are women. Longer life expectancy is one factor thought to contribute to this observation, but possible sex-specific biological mechanisms have received considerable attention from the research community. In the current issue of the Journal , Buckley et al. (Am J Epidemiol. 2019;188(7):1213–1223) use death certificate information on all deaths occurring among adults aged ≥60 years in Australia between 2006 and 2014 to evaluate sex/gender differences in rates of death with dementia (all types), AD dementia, and vascular dementia listed on the death certificate. The paper by Buckley et al. highlights several important methodological challenges for research examining sex/gender differences in risk of AD and related dementias, including challenges in measurement, survival bias and competing risks, and selection bias arising from sample selection. The current evidence on possible sex-specific biological risk factors for AD is intriguing, but there are numerous alternative explanations for differences in AD dementia and AD biomarkers between women and men. Triangulation of evidence from study designs with different strengths and weaknesses and transdisciplinary collaboration will be vital to generating conclusive evidence about sex/gender differences in risk of AD and related dementias.

Cohort or period components of trends can provide a rationale for new research or point to clues on the effectiveness of control strategies. Graphical display of trends guides models that quantify the experience of a population. In this paper, a method for smoothing rates by single year of age and year is developed and displayed to show the contributions of period and cohort to trends. The magnitude of the contribution of period and/or cohort in a model for trends may be assessed by the percentage of deviance explained and the relative contributions of cohort (C) and period (P) individually, known as the C-P score. The method is illustrated using Surveillance, Epidemiology, and End Results data (1975–2014) on lung and bronchial cancer mortality in females and prostate and colorectal cancer incidence in males. Smoothed age-period and age-cohort rates provide a useful first step in studies of etiology and the impact of disease control without imposing a restrictive model. We found that, in this data set, cohort predominates for female lung and bronchial cancer and period predominates for male prostate cancer. However, the effects change with age for male colorectal cancer incidence, indicating an age shift in relevant exposures. These methods are applied on an interactive website for both incidence and mortality at over 20 cancer sites in the United States. [ABSTRACT FROM AUTHOR]

Objectives Numerous studies reported an age-related deficit in verbal working memory (WM). Beyond the well-established general factors of cognitive aging, the alteration of the specific WM maintenance mechanisms may account for this deficit. This paper aims to investigate the hypothesis that WM attentional maintenance is impaired with age. Method In a WM task adapted to individual short-term memory and processing speed, younger and older participants maintained letters while verbally responding to a concurrent processing task, in order to constrain the use of rehearsal. Critically, the opportunity to use attentional maintenance was manipulated by varying the cognitive load (CL) of the concurrent processing via its nature and pace. Results Younger participants outperformed older participants and, in both groups, recall performance decreased as the CL increased. Importantly, in line with our predictions, the CL effect was modulated by age. Older adults benefited less from free pauses that allowed participants to engage in attentional maintenance of WM traces. Discussion Although still effective in normal aging, WM attentional maintenance seems to be altered. It could therefore be a good candidate to account for WM age-related deficits.

Aims This paper examines: (a) change over time (2001–2013) in recently reducing or ceasing drinking in the Australian population and (b) the reasons given for reducing or ceasing drinking in the most recent survey (2013); stratified by sex and age group. Short summary Rates of reducing and ceasing drinking increased between 2001 and 2013 in Australia. Young people were more likely to modify drinking due to lifestyle and enjoyment reasons; older groups were more likely to report health reasons. These trends contribute to the broader context of declining alcohol consumption in Australia. Methods Data are from five waves of the National Drug Strategy Household Survey (N = 119,397). Logistic regression models with interaction terms were used to identify a shift in sex or age over time in predicting reduction or cessation of drinking and to predict motivations for reducing or ceasing drinking by sex and age. Results Reports of recently reducing the quantity or frequency of drinking increased from 2001 to 2007 and remained stable between 2007 and 2013. There was a steady increase in the number of Australians reporting recently ceasing drinking from 2001 to 2013, with a significant effect for age (younger groups more likely than older groups to cease drinking in the past two waves). Reasons for reducing or ceasing drinking varied by age, with older people more likely to report health reasons and younger people more likely to report lifestyle reasons or enjoyment. Conclusion Increases over time in reports of reduction or cessation of drinking due to health, lifestyle, social and enjoyment reasons suggest that the social position of alcohol in Australia may be shifting, particularly among young people.

Background In Britain, the tobacco industry segments cigarettes into four price categories—premium, mid-price, economy and ultra-low-price (ULP). Our previous work shows that tobacco companies have kept ULP prices stable in real terms. Roll your own (RYO) tobacco remains cheaper still. Methods Analysis of 2001–08 General Household Survey data to examine trends in use of these cheap products and, using logistic regression, the profile of users of these products. Results Among smokers, the proportion using cheap products (economy, ULP and RYO combined) increased significantly in almost all age groups and geographic areas. Increases were most marked in under 24 year olds, 76% of whom smoked cheap cigarettes by 2008. All cheap products were more commonly used in lower socio-economic groups. Men and younger smokers were more likely to smoke RYO while women smoked economy brands. Smokers outside London and the South East of England were more likely to smoke some form of cheap tobacco even once socio-economic differences were accounted for. Conclusions This paper demonstrates that cheap tobacco use is increasing among young and disadvantaged smokers compromising declines in population smoking prevalence. Thus, tobacco industry pricing appears to play a key role in explaining smoking patterns and inequalities in smoking. [ABSTRACT FROM PUBLISHER]

Objective. The goals of this paper were: (a) to promote research using the National Social Life, Health and Aging Project (NSHAP) Wave 2 data by providing relevant background information for a broad range of chronic conditions and (b) to provide a framework for combining these chronic conditions into informative comorbidity indices. Method. The chronic conditions measured in NSHAP Wave 2 were grouped across several health domains: cardiovascular, endocrine and metabolic, cancer, lung, inflammatory and bone, neurological, and sensorimotor. Prevalences for each condition were reported as percentages and were also estimated separately by age group and gender. Additionally, 2 comorbidity indices were created: a Modified Charlson Comorbidity Index (CCI) that included conditions associated with mortality risk and the NSHAP Comorbidity Index (NCI) that included conditions from the Modified CCI as well as additional conditions related to overall health and function. Results. Hypertension, incontinence, arthritis, heart conditions, cancer, and diabetes were the most prevalent conditions. In general, prevalences of most chronic conditions increased with age. Additionally, there were several notable gender differences in chronic condition prevalence. Due to the inclusion of highly prevalent conditions, such as hypertension and incontinence, the mean comorbidity index score of the NCI was higher than that of the Modified CCI. Discussion. Wave 2 of NSHAP included a variety of measures assessing the chronic conditions that are the most prevalent in older adults. These data are a valuable resource for the study of the impact of chronic conditions on overall health and aging. [ABSTRACT FROM AUTHOR]

This article explores the theoretical binary that has tended to encompass the majority of scholarship with unaccompanied refugee young people (URYP) affected by armed conflict. In this paper, we argue that URYP scholars often theorise this population via either a trauma/victimisation framework or resiliency lens, which creates a distinct binary. While these opposing theoretical perspectives provide important insight into understanding URYP's experiences, this conceptual binary has tended to neglect the nexus of factors for URYP who are resourceful and determined in particular aspects of their lives, while simultaneously being vulnerable in others. We suggest that a more nuanced exploration of theoretical frameworks is necessary, specific to URYP's experiences. Moreover, we call for greater analysis of theories that emerge from both the Global North and, particularly, the Global South in order to gain a more holistic appreciation of the complex lives and realities of URYP, whether during armed conflict or in its aftermath. By uniting trauma and resilience theories and integrating theories from the Global South, from where a majority of URYP originate, scholars may provide a richer account of URYP that is not only beneficial for global discourse, but may have greater significance for URYP who attempt to make meaning out of their experiences.

Background: In 2015, new disability weights (DWs) for infectious diseases were constructed based on data from four European countries. In this paper, we evaluated if country, age, sex, disease experience status, income and educational levels have an impact on these DWs. Methods: We analyzed paired comparison responses of the European DW study by participants' characteristics with separate probit regression models. To evaluate the effect of participants' characteristics, we performed correlation analyses between countries and within country by respondent characteristics and constructed seven probit regression models, including a null model and six models containing participants' characteristics. We compared these seven models using Akaike Information Criterion (AIC). Results: According to AIC, the probit model including country as covariate was the best model. We found a lower correlation of the probit coefficients between countries and income levels (range rs: 0.97-0.99, P < 0.01) than between age groups (range rs: 0.98-0.99, P < 0.01), educational level (range rs: 0.98-0.99, P < 0.01), sex (rs = 0.99, P < 0.01) and disease status (rs = 0.99, P < 0.01). Within country the lowest correlations of the probit coefficients were between low and high income level (range rs = 0.89-0.94, P < 0.01). Conclusions: We observed variations in health valuation across countries and within country between income levels. These observations should be further explored in a systematic way, also in non-European countries. We recommend future researches studying the effect of other characteristics of respondents on health assessment. [ABSTRACT FROM AUTHOR]
