Individual and environmental factors underlying life space of older people – study protocol and design of a cohort study on life-space mobility in ol…
2012
Abstract Background A crucial issue for the sustainability of societies is how to maintain health and functioning in older people. With increasing age, losses in vision, hearing, balance, mobility and cognitive capacity render older people particularly exposed to environmental barriers. A central building block of human functioning is walking. Walking difficulties may start to develop in midlife and become increasingly prevalent with age. Life-space mobility reflects actual mobility performance by taking into account the balance between older adults internal physiologic capacity and the external challenges they encounter in daily life. The aim of the Life-Space Mobility in Old Age (LISPE) p…
Associations of Leisure-Time Physical Activity Trajectories with Fruit and Vegetable Consumption from Childhood to Adulthood: The Cardiovascular Risk…
2019
A physically active lifestyle and a diet rich in vegetables and fruits have a central role in promoting health. This study examined the associations between leisure-time physical activity (LTPA) trajectories and fruit and vegetable consumption (FVC) from childhood to middle age. The data were drawn from the Cardiovascular Risk in Young Finns Study with six age cohorts. Participants were 9 to 18 years (n = 3536
Sauna Bathing and Risk of Psychotic Disorders : A Prospective Cohort Study
2018
<b><i>Objective:</i></b> Sauna bathing has been suggested to promote mental well-being and relaxation, but the evidence is uncertain with respect to mental disorders. We aimed to assess the association of frequency of sauna bathing with risk of psychosis in the Kuopio Ischemic Heart Disease prospective population-based study. <b><i>Subjects and Methods:</i></b> Baseline sauna bathing habits were assessed in 2,138 men aged 42–61 years who had no history of psychotic disorders. Participants were classified into three groups based on the frequency of sauna bathing (once, 2–3, and 4–7 times per week). <b><i>Results:</i></b>…
Birth cohort differences in cognitive performance in 75- and 80-year-olds: a comparison of two cohorts over 28 years.
2021
Abstract Objective To evaluate cohort differences in cognitive performance in older men and women born and assessed 28 years apart. Methods Data in this study were drawn from two age-homogeneous cohorts measured in the same laboratory using the same standardized cognitive performance tests. Participants in the first cohort were born in 1910 and 1914 and assessed in 1989–1990 (Evergreen project, n = 500). Participants in the second cohort were born in 1938 or 1939 and 1942 or 1943 and assessed in 2017–2018 (Evergreen II, n = 726). Participants in both cohorts were assessed at age 75 and 80 years and were recruited from the population register. Cognitive performance was measured using the Dig…
Association of accelerometer‐measured physical activity and midlife income : A Northern Finland Birth Cohort 1966 Study
2023
This study investigated the association between physical activity (PA) and midlife income. The population-based data comprised employed members of the Northern Finland Birth Cohort 1966 (N = 2797). Using binned scatterplots and polynomial regressions, we evaluated the association between accelerometer-measured moderate PA (MPA), vigorous PA (VPA), and moderate-to-vigorous PA (MVPA) at 46 years old and register-based income at 50 years old. The models were adjusted for sex, marital status, number of children, education, adolescent PA, occupational physical strenuousness, and time preference. We found MPA (p < 0.001), VPA (p < 0.05), and MVPA (p < 0.001) to associate curvilinearly with income…
Changes in physical performance according to job demands across three cohorts of older workers in the Longitudinal Aging Study Amsterdam
2023
This study set out to evaluate the association between job demands at baseline and physical performance over a six-year period across three cohorts of older Dutch workers examined 10 years apart. Data were drawn from three cohorts (1992–1999, 2002–2009 and 2012–2019) of the Longitudinal Aging Study Amsterdam. Individuals aged 55–65 years from each cohort who worked for pay were included (n = 274, n = 416, n = 618, respectively). Physical performance was measured using gait speed and chair stand performance. A population-based job exposure matrix was used to indicate levels of exposure probability of physical (use of force and repetitive movements) and psychosocial (cognitive demands and tim…
Physical heaviness of work and sitting at work as predictors of mortality : a 26-year follow-up of the Helsinki Birth Cohort Study
2019
ObjectivesTo examine the relationships of late-career physical heaviness of work and sitting at work with mortality. A national-level job exposure matrix was used to determine the occupation-specific level of physical heaviness and sitting.DesignProspective cohort study between years 1990 and 2015.SettingCommunity.Participants5210 men and 4725 women from the Helsinki Birth Cohort Study with an occupational code at baseline (ages 45–57 years).Primary and secondary outcome measuresTotal, cardiovascular (International Classification of Diseases 10th Revision I00–I99), cancer (C00–C97) and external (S00–Y84) mortality.ResultsThe exposures, physical heaviness and sitting had a non-linear, invers…
Longitudinal physical activity patterns and the development of cardiometabolic risk factors during adolescence
2023
Purpose To examine the associations between longitudinal physical activity (PA) patterns and the development of cardiometabolic risk factors from adolescence to young adulthood. Methods This cohort study encompassed 250 participants recruited from sports clubs and schools, and examined at mean age 15 and 19. Device-measured moderate-to-vigorous PA was grouped into five patterns (via a data-driven method, using inactivity maintainers as a reference). The outcomes were: glucose, insulin, homeostasis model assessment for insulin resistance (HOMA-IR), total cholesterol, HDL and LDL cholesterol, triglycerides, blood pressure, and body mass index (BMI). Linear growth curve models were applied wit…
Higher carotid-radial pulse wave velocity is associated with non-melancholic depressive symptoms in men - findings from Helsinki Birth Cohort Study
2021
Background: Depression and cardiovascular disease (CVD) are major causes of global disease burden that are interrelated through mostly unknown mechanisms. We studied the relationship of melancholic and non-melancholic depressive symptoms with arterial stiffness, an important underlying mechanism of CVD. Methods: The Helsinki Birth Cohort Study recruited 683 previously extensively phenotyped subjects for this sub-study. Cross-sectional data along with responses regarding depressive symptoms were obtained for each participant. For evaluation of depressive symptoms, the Beck Depression Inventory (BDI)and subscales were used to measure melancholic and non-melancholic depressive symptoms. Arteri…
Walking, physical activity and life-space mobility among older people
2017
Autonomy in mobility is a central component of active ageing. Life-space mobility describes where, when, and how an individual reaches desired destinations. Walking, an important form of physical activity among older people, is a prerequisite for engaging in daily activities. This study explored the cross-sectional and longitudinal relationships between physical activity and life-space mobility. The associations of walking with reasons for going outdoors in different life-space areas, living arrangements, and environmental barriers to mobility were also examined. Data from two larger studies were used: the Life-Space Mobility in Old Age (LISPE) accelerometer substudy (n=174, median age 79.7…
