What Explains the Link Between Hearing and Vision Impairment and Cognitive Function? Analysis of Mediating Effects in the USA, England and Ireland.

Objectives: Hearing and vision impairments are associated with cognitive decline and dementia risk. Explanations for this include age-related processes impacting on sensory and cognitive function (common cause), or sensory impairments having a direct or indirect impact on cognition via social engagement, depression and physical activity (cascade). We tested whether associations between hearing, vision and episodic memory were mediated by allostatic load, social engagement, depression and physical activity.

Allostatic load and risk of hearing impairment.

Background: Prevention of hearing loss via addressing potentially modifiable risk factors may offer means of reducing the global burden of hearing loss. Prior studies reported associations between individual markers of inflammation and risk of hearing impairment. Allostatic load is an index of cumulative physiological stressors, including inflammation, to multiple biological systems.

The Impact of Volunteering and Its Characteristics on Well-being After State Pension Age: Longitudinal Evidence From the English Longitudinal Study of Ageing.

Objectives: Volunteering after retirement age is beneficial to well-being. This study furthers previous research by presenting a longitudinal analysis of the well-being of volunteers, compared to non-volunteers, based on characteristics of the voluntary work in which they participate.

Method: Participants were 3,740 people aged State Pension Age and over from the English Longitudinal Study of Ageing.

Who in Europe Works beyond the State Pension Age and under which Conditions? Results from SHARE.

There is much research about those who exit the labour market prematurely, however, comparatively little is known about people working longer and about their employment and working conditions. In this paper, we describe the employment and working conditions of men and women working between 65 and 80 years, and compare them with previous conditions of those retired in the same age group. Analyses are based on wave 4 data from the Survey of Health, Ageing and Retirement in Europe (SHARE) with information collected between 2009 and 2011 from 17,625 older men and women across 16 European countries.

Trajectories of vision in older people: the role of age and social position.

Visual impairment becomes more prevalent with age. Rather than a uniform decline in vision with age, the strength and direction of change varies between people. This study applies an analytical method that posits multiple trajectories in eyesight, allowing for a more specific description of developmental course of this health outcome and its relationship with social position.

Linking Quality of Work in Midlife to Volunteering During Retirement: a European Study.

There is increasing recognition that disadvantaged work and employment conditions over the life course, including psychosocial stress at work, have negative long-term effects on health at older ages. Yet, the question whether stress at work additionally influences the likelihood of participating in voluntary work during retirement still needs to be explored. This paper studies long-term influences of stressful work during adulthood (as defined by low control and low reward at work) on participation in voluntary work in older ages.
