Social Mobility and Health-Related Quality of Life Trajectory Classes Among Older Women and Men.

Objectives: Changes in socioeconomic status (SES) during life may impact health in old age. We investigated whether social mobility and childhood and adulthood SES are associated with trajectories of health-related quality of life (HrQoL) over a 17-year period.

Methods: We used data from the Helsinki Birth Cohort Study ( = 2003, 46% men, mean age 61.

Frailty in Late Midlife to Old Age and Its Relationship to Medical Imaging Use and Imaging-related Costs: A Longitudinal Study.

Background Frailty, defined as an increased vulnerability to and impaired recovery from stressors, is common in individuals in late midlife to old age. While frailty predisposes individuals to adverse health outcomes and increased health care utilization, how it impacts imaging service use and related costs remains unclear. Purpose To determine whether frailty is associated with greater use of imaging services and higher imaging-related costs.

Physical and mental functioning trajectory classes among older adults and their association with specialized healthcare use.

Background: Sex-specific physical and mental functioning trajectory classification could offer a way of understanding the differences in healthcare use at older age.

Methods: Using latent growth mixture models, sex-specific physical and mental functioning trajectory classes were formed for 1991 participants (mean age 61.5 years) of the Helsinki Birth Cohort Study.

The utilization of primary healthcare services among frail older adults - findings from the Helsinki Birth Cohort Study.

Background: The impact of frailty on primary healthcare service use, especially general practice office visits and remote contacts, is currently unknown. Further, little is known about the association of frailty with physiotherapy contacts.

Methods: We examined the utilization of primary healthcare services among 1064 participants from the Helsinki Birth Cohort Study between the years 2013 and 2017.

The utilization of specialized healthcare services among frail older adults in the Helsinki Birth Cohort Study.

Background: The association between frailty and specialized healthcare utilization is not well studied. We, therefore, examined the utilization of specialized healthcare services among frail Finnish older adults.

Methods: A sub-sample of 1060 participants of the Helsinki Birth Cohort Study were followed prospectively for specialized healthcare utilization from nationwide registers between the years 2013 and 2017.

Effects of military training on plasma amino acid concentrations and their associations with overreaching.

The diagnosis of overtraining syndrome and overreaching poses a great challenge. Military training aims at improving the physical performance of the conscripts, but an excessive training load could also lead to overreaching. This study of Finnish conscripts provides new insights into the pathophysiology of overreaching and overtraining through amino acids concentrations.
