Vegetation Change in Peatland Buffers as an Indicator of Active Areas of Run-On from Forestry

Our aim in this study was to evaluate whether coverage change in the vegetation of a forestry buffer wetland can be used to reveal a possible increase in nutrients. To achieve this, we followed changes in vegetation on two peatland buffers, and biomass with nitrogen content in one of them. Nutrient concentrations were periodically lower in the water inflow than in the outflow. Flooding caused a species change in favor of flood-tolerant grasses and Sphagna, but this species composition did not indicate a higher trophic level. Nitrogen content in the reference site's original surface peat layer, which was rich in woody remains, was higher than that of the newly formed, more acidic Sphagnum pe…

Motor speed and lower extremity strength as predictors of fall-related bone fractures in elderly individuals.

Background and aims: The purpose of this prospective population-based study was to examine the combined effects of motor speed and knee extension strength on risk of fall-related bone fractures in elderly individuals over a 10-year period. Methods: Participants were 307 men and women aged 75 or 80 years at baseline, who visited the research laboratory at the University of Jyvaskyla, Finland. Multi-choice motor speed tests and maximal isometric knee extension strength tests were carried out at baseline. Information on fractures was collected from hospital and health center records. The presence of impairment was defined as a score in the lowest tertile of sex- and age-stratified distribution…

Endogenous Hormones, Muscle Strength, and Risk of Fall-Related Fractures in Older Women

Background. Among older people, fracture-causing fall often leads to health deterioration. The role of endogenous hormone status and muscle strength on fall-related fracture risk is unclear. This study investigates if, after adjustment for bone density, endogenous hormones and muscle strength would predict fall-related limb fracture incidence in older community-dwelling women followed-up over 10 years. Methods. As a part of a prospective population-based study, 187 75-year-old women were investigated. Serum estradiol, testosterone, sex hormone binding globulin, and dehydroepiandrosterone sulfate concentrations were analyzed, and isometric muscle strength and bone mineral density were assess…

Fall-related injuries among initially 75- and 80-year old people during a 10-year follow-up.

The aim of this study was to investigate the occurrence, type, scene and seasonal variation of fall related injuries, and the impact of socio-economic factors, mobility limitation, and the most common diseases on the risk of injurious falls over a 10-year follow-up. Elderly residents of Jyvaskyla, Finland, aged initially 75 and 80 years, took part in the study in 1989-1990. The health and functional capacity assessments were carried out at the baseline. Injurious falls were monitored over a 10-year period. The rate of injurious falls per thousand person-years was 188 among women and 78 among men. Of all fall-related diagnoses, head injuries comprised 32%, upper limb injuries 27% and hip inj…
