Demographic aspects of aging

2021

Population aging is occurring in almost all developed countries, albeit with differences in timing and intensity. This unprecedented phenomenon is evident not only in the change in the population age structure, but also in the impressive increase in the average length of life. After describing past, current, and future population trends, this contribution presents theories explaining the reasons for this long-term process that is completely reshaping the age structure of the population. It also describes the inequalities in aging (focusing in particular on the differences by gender, education, and cause of death), and introduces some measures of the individual health and economic consequenc…

The Challenges in Moving from Ageing to Successful Longevity

2014

During the last decades survival has significantly improved and centenarians are becoming a fast-growing group of the population. Human life span is mainly dependent on environmental and genetic factors. Favourable modifications of lifestyle factors (e.g. physical activity, diet and not smoking) and healthcare (e.g. effective vascular disease prevention) have also increased human life span. Genetic factors contribute to the variation of human life span by around 25%, which is believed to be more profound after 85 years of age. It is likely that multiple factors influence life span and we need answers to questions such as: 1) What does it take to reach 100?, 2) Do centenarians have better he…

Do epigenetic clocks provide explanations for sex differences in lifespan? A cross-sectional twin study

2021

ABSTRACTBackgroundThe sex gap in life expectancy has been narrowing in Finland over the past four to five decades; however, on average, women still live longer than men. Epigenetic clocks are markers for biological aging that predict lifespan. In this study, we examined the mediating role of lifestyle factors on the association between sex and biological aging in younger and older adults.MethodsOur sample included same-sex younger and older twins (21-42-y, n = 1110; 50-76-y, n = 763) and younger opposite-sex twins (21-30-y, n = 302). Blood-based DNA methylation (DNAm) was used to compute epigenetic age acceleration by four epigenetic clocks as a measure of biological aging. Path modelling w…

Dietary Patterns and Healthy Ageing

2021

Ageing is a complex process in which multiple factors are involved that can contribute to determine whether a person will or not be affected by diseases that are more frequently observed in advanced age. The factors involved comprise genetic, environmental, behavioural, and dietary factors, which influence pathways that regulate the ageing process and the life expectancy, rendering longevity a multifaceted phenomenon. Even if a miraculous elixir or pill is not yet available, there is general agreement that nutrition has a major impact on the overall mortality and on the development of age-related chronic non-communicable diseases. Nutrition research has focused for decades on single nutrien…

Mortality in multiple sclerosis: a review.

2008

This work was undertaken to evaluate studies on mortality caused by multiple sclerosis (MS), to evaluate if useful inferences can be drawn from survival studies that can be applied to clinical practice. A literature search was carried out to find epidemiological studies on MS prognosis, survival, mortality and causes of death relevant to our aim. The World Health Organization (WHO) reports on worldwide cause-specific mortality were also considered. Studies were evaluated according to the duration of the follow-up study, the year of publication and the methodology used. We evaluated MS survival from a methodological point of view and considered if time trends could be drawn from study result…

A health promotion intervention to improve lifestyle choices and health outcomes in people with psychosis: a research programme including the IMPaCT …

2020

Background People with psychotic disorders have reduced life expectancy largely because of physical health problems, especially cardiovascular disease, that are complicated by the use of tobacco and cannabis. Objectives We set out to (1) chart lifestyle and substance use choices and the emergence of cardiometabolic risk from the earliest presentation with psychosis, (2) develop a pragmatic health promotion intervention integrated within the clinical teams to improve the lifestyle choices and health outcomes of people with psychosis and (3) evaluate the clinical effectiveness and cost-effectiveness of that health promotion intervention. Design We performed a longitudinal cohort study of peo…

Trying to control migration between zones in the world

2019

It is a fact that migration is a worrying problem in some world areas. Literature shows many studies about it. Nevertheless, no sound solutions have been proposed. Assuming that the key implied factors are development and demography, we suggest in this research, as a first step, to state a stochastic and dynamic demographic model neither considering sexes nor ages, but including the necessary and adequate economic, education and health variables. This model will be able to optimize, by means of a genetic algorithm, the amount and proportion of the main development indicators in different areas of the world along time, in order to reach the desired values of the population present in each ar…

Editorial on the special issue “Private Life Choices, Employment and Health”

2013

The health conditions of the German population have been subject to signifi cant changes in the past. Within the last forty years, for example, the life expectancy at birth of both men and women reported by the German Federal Statistical Offi ce rose by more than eight years. In recent years, chances of survival in the middle and old ages were responsible for the increase in life expectancy. In this respect – and to an extent never seen before – it is nowadays possible to spend one’s lifetime actively within the family and productively on the labour market. However, in times of a shrinking population, changes of the conditions on the labour market and new arrangements of private life choice…

Minority Integration in a Western City: An Agent-Based Modelling Approach

2019

This chapter describes the design and construction of an agent-based model we refer to as the ‘Simulation of Extended Time Integration’ (SETI) model. This model was designed with the goal of obtaining a better understanding of the conditions and mechanisms leading to the structural, social, and cultural integration of minorities into large Western societies. SETI is a virtual society with structural (employment, income, education) and demographic (marriage, reproduction, life expectancy) variables typical of Westerns countries. Initialization occurs after a hypothesized immigration event in which a single minority population settles into the majority population, bracketing the first decade …
