Excessive Dietary Intake of Vitamin A Is Associated with Reduced Bone Mineral Density and Increased Risk for Hip Fracture
This study investigated whether excessive dietary intake of vitamin A is associated with decreased bone mineral density and increased risk for hip fracture, and investigated the relation between nutrient intake and bone mineraldensity in a population-based, cross-sectional study. Expand
Smoking, Antioxidant Vitamins, and the Risk of Hip Fracture
A role for oxidant stress in the adverse effects on the skeleton of smoking is suggested, and that an insufficient dietary intake of vitamin E and C may substantially increase the risk of hip fracture in current smokers, whereas a more adequeate intake seems to be protective. Expand
Population-based screening for primary hyperparathyroidism with serum calcium and parathyroid hormone values in menopausal women.
Substantial prevalence of sporadic primary hyperparathyroidism is demonstrated in a risk group and operative findings suggested underdiagnosis of the disorder. Expand
Survival after hip fracture
The objective of this study was to establish the survival after hip fracture in women and to assess the impact of comorbidity on mortality, and to study excess mortality of hip fracture patients compared to controls using survival curves and proportional hazard regression models. Expand
Bone Metabolism in Endurance Trained Athletes: A Comparison to Population-Based Controls Based on DXA, SXA, Quantitative Ultrasound, and Biochemical Markers
Low bone turnover in runners, indicated by lower levels of PTH and biochemical markers of bone metabolism, point to an influence of endurance running at the cellular level. Expand
Primary Hyperparathyroidism Revisited in Menopausal Women with Serum Calcium in the Upper Normal Range at Population-based Screening 8 Years Ago
Population-based screening showed 2.1% prevalence of primary hyperparathyroidism (pHPT) in postmenopausal women. Individuals with total serum (s)-calcium levels of 2.55 mmol/L or more at screeningExpand
Bone Metabolism During Exercise and Recovery: The Influence of Plasma Volume and Physical Fitness
Bone turnover and PTH secretion was stimulated by exercise, and low basal levels of PTH and high BMD were induced by a high level of physical fitness, and these observations correlate well with the favorable effects of exercise and training on bone mass. Expand
Risk of arrhythmias in 52 755 long-distance cross-country skiers: a cohort study.
Among male participants of a 90 km cross-country skiing event, a faster finishing time and a high number of completed races were associated with higher risk of arrhythmia, mainly driven by a higher incidence of AF and bradyarrhythmias. Expand
Risk factors for fractures of the distal forearm: A population-based case-control study
It is concluded that lifestyle factors did not discriminate between fracture patients and controls in this strict population-based investigation, suggesting that in affluent Western societies, with their high fracture rate, most individuals have an osteoporosis-prone way of life. Expand
Vitamin D is related to blood pressure and other cardiovascular risk factors in middle-aged men.
Serum levels of 1,25-(OH)2-vitamin D, 25-OH-v vitamin D, and blood pressure were measured in 34 middle-aged men and metabolic cardiovascular risk factors were evaluated by means of intravenous glucose and fat tolerance tests, euglycemic hyperinsulinemic clamp, lipoprotein measurements, and lipop Protein lipase activity determinations.
