Associations of Habitual Skeletal Loading with Bone Changes During the Menopausal Transition: A Follow-up Study.

Purpose: While weight-bearing physical activity (PA) benefits bone health, it remains unclear whether PA can counteract hormone-driven menopausal bone deterioration. This secondary analysis of a population-based prospective follow-up study examined changes in bone health indicators around menopause and evaluated whether accelerometer-measured habitual skeletal loading is associated with these changes.

Methods: A total of 189 initially perimenopausal women without estrogen therapy (mean age 52 [SD 2] years) were followed until they became postmenopausal (mean follow-up time 15 [9] months).

Health characteristics and health behaviours in male former contact sports participants: comparison with general population controls in a Finnish cohort study.

Background: Athletes who have a history of participation in contact sports appear to subsequently experience elevated rates of neurodegenerative diseases such as dementia but have a lower incidence of cardiovascular disease and selected cancers. We quantified the occurrence of little-examined cardiometabolic and mental health outcomes, plus associated lifestyle factors, in a group of former contact sports athletes and a general population sample.

Methods: In this cohort study, male former elite athletes active between 1920 and 1965 in soccer (N=303), boxing (N=281), and wrestling (N=318) were recruited using sports yearbooks and the administrative records of sports associations.

Association Between Accelerometer-Measured Physical Activity and Mobility Limitations in Twins.

Background: The associations between mobility limitations and device-measured physical activity are sparsely studied. In this study, these associations are studied among community-dwelling older twins.

Methods: This cross-sectional study utilized data gathered in 2014-2016 for the MOBILETWIN study.

Longitudinal leisure-time physical activity profiles throughout adulthood and related characteristics: a 36-year follow-up study of the older Finnish Twin Cohort.

Background: Personalized interventions aiming to increase physical activity in individuals are effective. However, from a public health perspective, it would be important to stimulate physical activity in larger groups of people who share the vulnerability to be physically inactive throughout adulthood. To find these high-risk groups, we identified 36-year leisure-time physical activity profiles from young adulthood to late midlife in females and males.

Physical activity, physical fitness and self-rated health: cross-sectional and longitudinal associations in adolescents.

Objectives: To evaluate the independent associations of physical activity and physical fitness with self-rated health in adolescents.

Methods: Data from a 2-year observational study (2013-2015) were used (n=256, 58% girls, 13.7±0.
