Associations of socio-economic position and disability among older women in Britain and Jyväskylä, Finland
2005
The aim was to compare the pattern of associations in measures of socio-economic position and disability among British and Finnish older women. In Britain data from the British Women's Heart and Health Study was used. Women from 23 towns took part in a nurse-assessed medical examination and postal questionnaire (n = 4286). In Finland, data from the Evergreen study was used. Eight hundred and four women from the city of Jyväskylä were interviewed at home. Socio-economic position was measured according to social class in childhood, education, use of a car, home ownership and previous occupation. Disability measures included questions on difficulties in washing/dressing and climbing stairs. Lo…
A twin study on the heritability of walking ability among older women
2006
BACKGROUND This study examined the role of genetic and environmental factors explaining individual differences in women's walking ability in old age. METHODS A maximal walking speed test over 10 meters and a 6-minute walking endurance test were done under standard conditions among 92 monozygotic and 105 dizygotic pairs of twin sisters reared together, aged 63-75 years. RESULTS The mean maximum walking speed was 1.73 +/- 0.32 m/s and the mean distance covered in the 6-minute walking test was 525.6 +/- 77.3 m. Multivariate genetic modeling showed that a minor part of the variances in walking speed (16%, 95% confidence interval [CI]: 0%-54%) and endurance (20%, 95% CI: 0%-56%) were accounted f…
Le vieillissement des personnes en situation de handicap : un regard démographique sur la Bourgogne-Franche-Comté
2018
The aging of people with disabilities has become, in the last forty years, a significant issue in the medico-social sector and also in our society. The lengthening of life is a positive phenomenon, a result of the efforts to professionalize the accompaniment of people with disabilities. Aging is a process, certainly irreversible, but natural. If a few people are the rare witnesses, in the 1980s, the phenomenon grows with time and becomes a demographic phenomenon. For the demographer, the notion of aging applies to a population and not to individuals. The observation of this process makes it possible to predict the trend of the changing needs of a population in the health, social and medico-…
Body Fat and Mobility Are Explained by Common Genetic and Environmental Influences in Older Women
2008
In older adults, mobility limitations often coexist with overweight or obesity, suggesting that similar factors may underlie both traits. This study examined the extent to which genetic and environmental influences explain the association between adiposity and mobility in older women. Body fat percentage (bioimpedance test), walking speed over 10 m, and distance walked in a 6-min test were evaluated in 92 monozygotic (MZ) and 104 dizygotic (DZ) pairs of twin sisters reared together, aged 63-76 years. Genetic and environmental influences on each trait were estimated using age-adjusted multivariate genetic modeling. The analyses showed that the means (and s.d.) for body fat percentage, walkin…
Force Platform Balance Measures as Predictors of Indoor and Outdoor Falls in Community-Dwelling Women Aged 63-76 Years
2008
Background. Inability to maintain balance while standing increases risk of falls in older people. The present study assessed whether center of pressure (COP) movement measured with force platform technology predicts risk for falls among older people with no manifest deficiency in standing balance. Methods. Participants were 434 community-dwelling women, aged 63-76 years. COP was measured in six stances on a force platform. Following balance tests, participants reported their falls with 12 monthly calendars. Incidence rate ratios (IRR) with 95% confidence intervals (CI) were computed from negative binomial regression models. For the analysis, those with>/=1 fall indoors were coded"indoor fal…
Mothers' and fathers' personality and parenting: the mediating role of sense of competence.
2009
This prospective longitudinal study addressed 3 key questions regarding the processes of parenting in a large community sample of mothers (n = 589) and fathers (n = 518). First, the collective impact of parental Big Five personality dimensions on overreactive and warm parenting, assessed 6 years later by adolescents, was examined. Second, mediation of these associations by sense of competence in the parenting role was addressed. Third, it was explored to what extent associations were similar for mothers and fathers. Agreeableness and Extraversion were related to lower levels of overreactivity and higher levels of warmth. Sense of competence completely mediated relations between personality …
Can personality predict retirement behaviour? A longitudinal analysis combining survey and register data from Norway.
2017
Published version of an article in the journal: European Journal of Ageing. Also available from the publisher at: http://dx.doi.org/10.1007/s10433-011-0212-6 This study investigates how far personality can predict the timing and routes of people’s retirement. It uses a large comprehensive Norwegian survey, with larger sample size than earlier related studies, providing estimates of personality based on the five-factor model. The survey data are matched with administrative data, allowing observations of retirement over the 2002–2007 period. The analysis distinguishes between the disability and the non-disability retirements. Retirement is investigated using discrete time, competing risk, log…
Factors Affecting Hesitancy to mRNA and Viral Vector COVID-19 Vaccines among College Students in Italy
2021
Vaccine hesitancy (VH) may be significant in jeopardizing efforts to mass containment of COVID-19. A cross-sectional survey was carried out on a sample of 2667 Italian college students, before the COVID-19 vaccines became available for this age group (from 7 May to 31 May 2021). An online survey was created to obtain information about socio-demographic, health-related, and psychological factors linked to mRNA and viral vector COVID-19 vaccines. Statistically significant higher VH (30.4%) and vaccine resistance (12.2%) rates were found for viral vector than mRNA COVID-19 vaccines (7.2% and 1.0%, respectively; p < 0.001). Factors related to viral vector VH were partially different from tho…
Sense and sensibility: using a model to examine the relationship between public pre-school places and fertility
2019
This paper presents a stochastic dynamic mathematical model, in which a Family Policy Index (XFPI) is included to measure and compare two different models of provision of resources to support families with children from 0 to 3 years old. The main variables in this model are the XFPI, fertility, mortality, emigration and immigration rates. This mathematical model was validated in two different countries, Spain and Norway, during the 2007–2015 period. A sensitivity analysis was applied to simulate the future trend (2016–2030), examining the influence of providing public pre-school services (0 to 3 years) on (XISF). The results obtained show that these services may indeed have an influence on …
Female reactions to male absence after pairing in the pied flycatcher
1994
Mating with an already mated pied flycatcher (Ficedula hypoleuca) male is costly for a female. Two hypotheses explain why some females still mate with already mated males. The deception hypothesis suggests that some females mate with already mated males since it is difficult to assess perfectly the mating status of a male with separate territories (polyterritoriality). The search cost hypothesis states that females are aware of male mating status but the costs of searching for an unmated male exceed costs associated with the status of secondary female. One potential cue that could disclose a male's mating status is the existence of brief visits to the primary territory by polyterritorial ma…
