A healthy Nordic diet and physical performance in old age : findings from the longitudinal Helsinki Birth Cohort Study

2016

AbstractEpidemiological studies have shown that a number of nutrients are associated with better physical performance. However, little is still known about the role of the whole diet, particularly a healthy Nordic diet, in relation to physical performance. Therefore, we examined whether a healthy Nordic diet was associated with measures of physical performance 10 years later. We studied 1072 participants from the Helsinki Birth Cohort Study. Participants’ diet was assessed using a validated 128-item FFQ at the mean age of 61 years, and a priori-defined Nordic diet score (NDS) was calculated. The score included Nordic fruits and berries, vegetables, cereals, PUFA:SFA and trans-fatty acids ra…

Occupational Gerontology: Work-Related Determinants of Old Age Health and Functioning

2014

Work is one of the essential functions during the human life span. We spend almost half of our lives occupationally active. Therefore, several different work-related determinants are affecting our lives. In recent years, there has been an increasing knowledge about work-related factors and their effect on health and functioning. Both cross-sectional and longitudinal studies have provided strong evidence that both positive and negative exposures in work influence our well-being. This chapter gives an overview of recent literature about the associations between work, working conditions, and health. Within this chapter, we summarize the current knowledge on the association between work-related…

Body composition and changes in health-related quality of life in older age: a 10-year follow-up of the Helsinki Birth Cohort Study

2020

Abstract Purpose Most studies examining the associations between body composition and health-related quality of life (HRQoL) in older age have been cross-sectional and analyzed only fat or lean mass. Hence, it is poorly known whether fat and lean mass are independently associated with subsequent changes in HRQoL. We investigated whether baseline lean and fat mass are associated with changes in HRQoL over a 10-year period in older adults. Methods We studied 1044 men and women from the Helsinki Birth Cohort Study (age 57–70 years at baseline). Bioelectrical impedance analysis was used to derive baseline fat mass index (FMI, fat mass/height2) and lean mass index (lean mass/height2), dichotomiz…

Progression of functional limitations in relation to physical activity: a life course approach

2010

Abstract In this minireview, we summarize the research results to date on the progression of functional limitations and the role of physical activity during the life course in preventing risk factor accumulation. In addition, socioeconomic and health disparities play a role in the development process of functional limitation throughout life. We discuss the potential role of physical activity in alleviating this process. Functional limitations usually develop gradually over an extended period of time while the level of physical functioning varies greatly already from midlife onwards. Current research strongly suggests that physical activity has a beneficial effect on functional limitations a…

Telomere length and physical performance among older people-The Helsinki Birth Cohort Study.

Coronary artery calcium and physical performance as determinants of mortality in older age: The AGES-Reykjavik Study

2013

Background. Coronary artery calcium (CAC) and physical performance have been shown to be associated with mortality, but it is not clear whether one of them modifies the association. We investigated the association between the extent of CAC and physical performance among older individuals and explored these individual and combined effects on cardiovascular disease (CVD) mortality and non-CVD mortality. Methods. We studied 4074 participants of the AGES–Reykjavik Study who were free from coronary heart disease, had a CAC score calculated from computed tomography scans and had data on mobility limitations and gait speed at baseline in 2002–2006 at a mean age of 76 years.

Ontological diversity in gaming disorder measurement: a nationally representative registered report

2022

Gaming-related health problems have been researched since the 1980s with numerous different ontologies as reference systems, from self-assessed ‘game addiction’ to ‘pathological gambling’ (in the Diagnostic and Statistical Manual of Mental Disorders [DSM]-IV), ‘internet gaming disorder’ (in the third section of the DSM-5) and most recently ‘gaming disorder’ (in the International Classification of Diseases [ICD]-11). Our goal was to investigate how screening instruments that derive from different ontologies differ in identifying associated problem groups. By using four central screening instruments, each representing a different ontological basis, we hypothesized differences and similarities…

Work-Related Biomechanical Exposure and Job Strain as Separate and Joint Predictors of Musculoskeletal Diseases: A 28-Year Prospective Follow-up Study

2017

We investigated how work-related biomechanical exposure and job strain in midlife separately and jointly predicted back and degenerative musculoskeletal diseases (MSDs). A total of 6,257 employees participated in the Finnish Longitudinal Study on Aging Municipal Employees (FLAME) in 1981 and were followed up for 28 years. Risk ratios and the relative excessive risk due to interaction and 95% confidence intervals were modeled for separate and joint prediction estimates, respectively. After adjustment for confounders, job strain predicted degenerative MSDs among women after 4 and 11 years of follow-up. After 11 years, both exposures predicted both types of MSDs among men. Joint exposure predi…

Social Participation Considered as Meaningful in old age − the Perceptions of Senior Housing Residents in Finland

2023

AbstractAs populations across the world age, there is a recognised need for promoting social participation in older adults. Previous studies related to social participation have addressed that interactions perceived as meaningful may improve quality of life in old age. However, what is less clear is the nature of such participation from the perspective of older adults, as the vast majority of studies have been quantitative. The present study aimed to explore what characterises social participation that contributes to a meaningful everyday life, from the viewpoint of independently living Finnish older adults. Thematic analysis was used as an interpretative method drawing on semi-structured i…

Persistence of the effect of birth size on dysglycaemia and type 2 diabetes in old age: AGES-Reykjavik Study

2012

The temporal association between executive function and life-space mobility in old age

2018

Background Life-space mobility, an indicator of community mobility, describes person’s movements in terms of the distance from home, the frequency of movement, and the need of assistance for movement. Executive function (EF) is a higher-order cognitive function that supervises motor control and plays a key role in a person’s ability to function independently. Cognitive impairment often co-occurs with restricted life-space mobility; however, the direction of the longitudinal associations between EF and life-space mobility is unclear. The aim of this study was to investigate the temporal associations between EF and life-space mobility among community-dwelling older people. Methods One hundred…
