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

Telomere length has been suggested a biomarker of aging and is associated with several chronic diseases. However, the association between telomere length and physical performance is not well known. Using both cross-sectional and longitudinal data, we studied 582 women and 453 men from the Helsinki Birth Cohort Study at two time-points; a baseline examination in 2001-2004 at a mean age of 61 years and a follow-up examination approximately 10 years later in 2011-2013.

The Healthy Nordic Diet and Mediterranean Diet and Incidence of Disability 10 Years Later in Home-Dwelling Old Adults.

Background/objective: Diet has a major impact on a person's health. However, limited information exists on the long-term role of the whole diet on disability. We investigated the association of the healthy Nordic diet and the Mediterranean diet with incident disability 10 years later.

Telomere Length and Frailty: The Helsinki Birth Cohort Study.

Objectives: Telomere length is associated with aging-related pathologies. Although the association between telomere length and frailty has been studied previously, only a few studies assessing longitudinal changes in telomere length and frailty exist.

Design: Longitudinal cohort study.

Glucose regulation and physical performance among older people: the Helsinki Birth Cohort Study.

Aims: To assess whether disturbances in glucose regulation are associated with impairment in physical performance during a 10-year follow-up.

Methods: 475 Men and 603 women from the Helsinki Birth Cohort Study were studied. Glucose regulation was evaluated with a 2-h 75-g oral glucose tolerance test (OGTT) in 2001-2004.

Body composition as a predictor of physical performance in older age: A ten-year follow-up of the Helsinki Birth Cohort Study.

Background: This study assessed how different measures of body composition predict physical performance ten years later among older adults.

Methods: The participants were 1076 men and women aged 57 to 70 years. Body mass index (BMI), waist circumference, and body composition (bioelectrical impedance analysis) were measured at baseline and physical performance (Senior Fitness Test) ten years later.

The healthy Nordic diet predicts muscle strength 10 years later in old women, but not old men.

Background: a number of nutrients have been found to be associated with better muscle strength and mass; however, the role of the whole diet on muscle strength and mass remains still unknown.

Objective: to examine whether the healthy Nordic diet predicts muscle strength, and mass 10 years later among men and women.

Methods: about 1,072 participants belong to the Helsinki Birth Cohort Study, born 1934-44.

Objectively measured physical activity and physical performance in old age.

Background: physical performance is a key factor that determines how older people cope with daily tasks and maintain independency. There is strong evidence suggesting that physical activity (PA) is important in maintaining physical performance in old age. However, most studies have been done using self-reported PA.

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

Epidemiological 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.

Prenatal and childhood growth and physical performance in old age--findings from the Helsinki Birth Cohort Study 1934-1944.

Health in adulthood is in part a consequence of development and growth taking place during sensitive periods in early life. It has not been explored previously whether early growth is associated with physical performance in old age from a life course perspective taking into account health-related behavior, biological risk factors, and early life experiences. At a mean age of 71 years, physical performance was assessed using the Senior Fitness Test (SFT) in 1078 individuals belonging to the Helsinki Birth Cohort Study.

Longitudinal changes in functional capacity: effects of socio-economic position among ageing adults.

Introduction: Health and functional capacity have improved especially in Western countries over the past few decades. Nevertheless, the positive secular trend has not been able to decrease an uneven distribution of health. The main aim of this study was to follow-up changes in functional capacity among the same people in six years time and to detect whether the possible changes vary according to socio-economic position (SEP).

Self-rated health (SRH) and socioeconomic position (SEP) among urban home-dwelling older adults.

The main purpose of this study was to examine the association of education and adequacy of income with self-rated health (SRH) among home-dwelling older people aged 75 and over living in the urban area. A cross-sectional survey from 2008 was used to study 1395 older adults aged 75 and over living in one of the central areas of the city center of Helsinki, the capital of Finland. Associations of SRH with, education and adequacy of income were tested using ordinal regression model.

Comparison of self-rated health in older people of St. Petersburg, Russia, and Tampere, Finland: how sensitive is SRH to cross-cultural factors?

The aim of this study was to examine if there are differences in self-rated health (SRH) between older people in St. Petersburg, Russia, and Tampere, Finland. Two SRH measures were examined: a global measure without any frame of reference, and an age-comparative SRH with an explicitly elicited reference of age peers.
