Project description:The study focuses on understanding the association between parental socio-economic status (SES) and the likelihood of women experiencing a first birth while single, and identifying societal factors that influence this association in 18 North American and European societies. Previous research has shown that single motherhood occurs disproportionately among those from with lower a lower parental SES. The study assesses whether this is caused by parental SES differences in the risk of single women experiencing a first conception leading to a live birth or by parental SES differences in how likely women are to enter a union during pregnancy. Additionally, an assessment is made of whether cross-national differences in these associations can be explained by a country's access to family planning, norms regarding family formation, and economic inequality. Across countries, a negative gradient of parental SES was found on the likelihood of single women to experience a first pregnancy. The negative gradient was stronger in countries with better access to family planning. In some countries, the negative gradient of parental SES was aggravated during pregnancy because women from lower parental SES were less likely to enter a union. This was mostly found in societies with less conservative norms regarding marriage. The results suggest that certain developments in Western societies may increase socio-economic differentials in family demography.Supplementary informationThe online version contains supplementary material available at 10.1007/s10680-021-09591-3.

Project description:There is growing interest in the contribution of offspring educational attainment to parents' health outcomes. However, less is known about the impacts of offspring socio-economic status (SES) on parents' cognitive decline or about the role of offspring SES disadvantage. We used data from the Mexican Health and Aging Study (n = 10,426) to evaluate the impact of adult child SES disadvantage on parents' verbal memory trajectories over fourteen years (2001-2015). We estimated linear mixed models and used measures of adult child SES (educational, financial, and employment) disadvantage. Our most robust finding was that having an adult child with less than secondary education was associated with faster decline in verbal memory z-scores for older women (β: -0.009 [95% CI: -0.01, -0.001]) and men (β: -0.01 [95% CI: -0.02, -0.01]). Although poor adult child financial well-being was associated with a faster decline in parents' verbal memory z-scores, this finding was less consistent across model specifications. Additional analyses also suggested some evidence of heterogeneity by parents' own educational attainment and gender. These findings highlight the potential importance of children's socio-economic status for the cognitive aging of their older parents.

Project description:This contribution introduces the work of the European Union network Sustainable Transport in Europe and Links and Liaisons to America (STELLA) in the first section and examines especially social and behavioural aspects of sustainable transport from a transatlantic perspective in the second section. One of the most significant societal trends, the ageing of societies, is surveyed and its implications for mobility behaviour are shown. The sustainability of this behaviour is considered along with constraints and drivers of this behaviour in Europe and North America. The contribution takes up relevant policy issues and concludes with a discussion of a transatlantic research agenda on social and behavioural aspects of sustainable transport especially concerning the elderly.

Project description:ImportanceUV radiation emissions from indoor tanning devices are carcinogenic. Regulatory actions may be associated with reduced exposure of UV radiation at a population level.ObjectiveTo estimate the long-term health and economic consequences of banning indoor tanning devices or prohibiting their use by minors only in North America and Europe compared with ongoing current levels of use.Design, setting, and participantsThis economic analysis modeled data for individuals 12 to 35 years old in North America and Europe, who commonly engage in indoor tanning. A Markov cohort model was used with outcomes projected during the cohort's remaining life-years. Models were populated by extracting data from high-quality systematic reviews and meta-analyses, epidemiologic reports, and cancer registrations.Main outcomes and measuresMain outcomes were numbers of melanomas and deaths from melanoma, numbers of keratinocyte carcinomas, life-years, and health care and productivity costs. Extensive sensitivity analyses were performed to assess the stability of results.ResultsIn an estimated population of 110 932 523 in the United States and Canada and 141 970 492 in Europe, for the next generation of youths and young adults during their remaining lifespans, regulatory actions that ban indoor tanning devices could be expected to gain 423 000 life-years, avert 240 000 melanomas (-8.2%), and avert 7.3 million keratinocyte carcinomas (-7.8%) in North America and gain 460 000 life-years, avert 204 000 melanomas (-4.9%), and avert 2.4 million keratinocyte carcinomas (-4.4%) in Europe compared with ongoing current levels of use. Economic cost savings of US $31.1 billion in North America and €21.1 billion (US $15.9 billion) in Europe could occur. Skin cancers averted and cost savings after prohibiting indoor tanning by minors may be associated with one-third of the corresponding benefits of a total ban.Conclusions and relevanceBanning indoor tanning may be associated with reduced skin cancer burden and health care costs. Corresponding gains from prohibiting indoor tanning by minors only may be smaller.

Project description:Background:Frailty, a state of vulnerability to poor resolution of homoeostasis after a health stressor, may be a result of cumulative decline in many physiological systems across the life course and its prevalence and incidence rates vary widely depending on the place and population subgroup. Objective:This study aims to examine social and economic factors as predictors of worse frailty status over 2 years of follow-up in a sample of community-dwelling older adults from the International Mobility in Aging Study. Methods:We analyzed 2012 baseline and 2014 follow-up (n = 1,724) data on participants from a populational-based, longitudinal study conducted in 4 countries (e.g., Brazil, Colombia, Albania, and Canada). Frailty was defined according to the Fried's phenotype and Poisson regression models with robust standard errors were performed to estimate the relative risks of becoming frail. Results:In our study, 366 (21.2%) participants migrated to a worse stage of frailty. After statistical adjustment (e.g., participant age, sex, and study site), insufficient income (RR = 1.40; 95% CI = 1.00-1.96) and having partner support (RR = 0.80; 95% CI = 0.64-1.01) were predictors of incident frailty status. Conclusion:Notably, transitions in frailty status were observed even in a short range of time, with sociodemographic factors predicting incident frailty.

Project description:Comparison of whole blood DNA methylation in 45 year-old humans with low and high childhood and adulthood socio-economic position Background: Disadvantaged socio-economic position (SEP) in childhood is associated with increased adult mortality and morbidity. We aimed to establish whether childhood SEP was associated with differential methylation of adult DNA. Methods: Forty adult males from the 1958 British Birth Cohort Study were selected from SEP extremes in both early childhood and mid-adulthood. We performed genome-wide methylation analysis on blood DNA taken at 45y using MeDIP (methylated DNA immunoprecipitation). We mapped in triplicate the methylation state of promoters of ~20,000 genes and 400 microRNAs. Probe methylation scores were averaged across triplicates and differential methylation between groups of individuals was determined. Differentially methylated promoter sites of selected genes were validated using pyrosequencing of bisulfite-converted DNA. Results: 9,112 variably methylated probes (from N=223,359 on the microarray) corresponded to 6,176 gene promoters with at least one variable probe. Unsupervised hierarchical clustering of probes obtained from the 500 most variable promoters revealed a cluster enriched with high SEP individuals confirming that SEP differences contribute to overall epigenetic variation. Methylation levels for 1252 gene promoters were associated with childhood SEP vs 545 promoters for adulthood SEP. Functionally, associations with childhood SEP appear in promoters of genes enriched in key cell signalling pathways. The differentially methylated promoters associated with SEP cluster in megabase-sized regions of the genome. Conclusions: Adult blood DNA methylation profiles show more associations with childhood SEP than adult SEP. Organization of these associations across the genome suggests a well-defined epigenetic pattern linked to early socio-economic environment.

Project description:BackgroundIn a rare disorder such as Huntington's disease (HD), a global network of clinical trial sites with access to patients speeds up recruitment into clinical trials. The objective was to test the hypothesis that demographics, HTT genotype, clinical spectrum, and progression are similar in HD participants of two large observational HD studies, the European Huntington's Disease Network's European REGISTRY study and the North American COHORT study.MethodsREGISTRY cross-sectional data were available from a total of 7,384 participants (1,125 [15.2%] premanifest and 6,259 [84.8%] manifest HD). COHORT cross-sectional data from 1,499 participants at 44 study sites were available (175 pre-HD [11.7%], 1,324 manifest HD [88.3%]). Participants were assessed clinically using the Unified Huntington's Disease Rating Scale (UHDRS). Longitudinal data were available for total motor score and cognitive performance in more than 50% of REGISTRY participants and more than 70% of COHORT participants.ResultsDemographics, HTT genotypes, phenotype, and progression were similar in the two studies. Patients in Europe were prescribed antidyskinetics more frequently, and antidepressants less frequently, than in North America. In either study, participants on antidyskinetic medication had higher UHDRS total motor scores, worse function assessment scores, and worse cognitive scores than those taking antidepressants or no medication. In contrast, motor, function assessment, and cognitive scores were broadly similar in participants taking antidepressants or no medication. The differences in cognitive performances between languages were small.ConclusionsOur data suggest that HD patients, and the way they are assessed, are similar across two continents with different cultures and languages.

Project description:Alcoholic liver diseases comprise a spectrum of clinical disorders and changes in liver tissue that can be detected by pathology analysis. These range from steatosis to more severe signs and symptoms of liver disease associated with inflammation, such as those observed in patients with alcoholic hepatitis or cirrhosis. Although the relationship between alcohol consumption and liver disease is well established, severe alcohol-related morbidities develop in only a minority of people who consume alcohol in excess. Inter-individual differences in susceptibility to the toxic effects of alcohol have been studied extensively-they include pattern of alcohol consumption, sex, environmental factors (such as diet), and genetic factors, which vary widely among different parts of the world. Alcoholic liver disease is becoming more common in many parts of Asia, but is decreasing in Western Europe. Treatment approaches, including availability of medications, models of care, and approach to transplantation, differ among regions.

Project description:Species become invasive if they (i) are introduced to a new range, (ii) establish themselves, and (iii) spread. To address the global problems caused by invasive species, several studies investigated steps ii and iii of this invasion process. However, only one previous study looked at step i and examined the proportion of species that have been introduced beyond their native range. We extend this research by investigating all three steps for all freshwater fish, mammals, and birds native to Europe or North America. A higher proportion of European species entered North America than vice versa. However, the introduction rate from Europe to North America peaked in the late 19th century, whereas it is still rising in the other direction. There is no clear difference in invasion success between the two directions, so neither the imperialism dogma (that Eurasian species are exceptionally successful invaders) is supported, nor is the contradictory hypothesis that North America offers more biotic resistance to invaders than Europe because of its less disturbed and richer biota. Our results do not support the tens rule either: that approximately 10% of all introduced species establish themselves and that approximately 10% of established species spread. We find a success of approximately 50% at each step. In comparison, only approximately 5% of native vertebrates were introduced in either direction. These figures show that, once a vertebrate is introduced, it has a high potential to become invasive. Thus, it is crucial to minimize the number of species introductions to effectively control invasive vertebrates.

Project description:Melanin-based dark colouration is beneficial for insects as it increases the absorption of solar energy and protects against pathogens. Thus, it is expected that insect colouration is darker in colder regions and in regions with high humidity, where it is assumed that pathogen pressure is highest. These relationships between colour lightness, insect distribution, and climate between taxa and subtaxa across continents have never been tested and compared. Here we analysed the colour lightness of nearly all butterfly species of North America and Europe using the average colour lightness of species occurring within 50 km × 50 km grid cells across both continents as the dependent variable and average insolation, temperature and humidity within grid cells as explanatory variables. We compared the direction, strength and shape of these relationships between butterfly families and continents. On both continents, butterfly assemblages in colder and more humid regions were generally darker coloured than assemblages in warmer and less humid regions. Although these relationships differed in detail between families, overall trends within families on both continents were similar. Our results add further support for the importance of insect colour lightness as a mechanistic adaptation to climate that influences biogeographical patterns of species distributions.
