Aims<p> The aim was to investigate the long-term association between leisure time physical activity and hip areal bone mineral density (aBMD), in addition to change in hip aBMD over time, in 32–86 years old women and men.<p> <p>Methods <p>Data were retrieved from the 2001, 2007–2008, and 2015–2016 surveys of the Tromsø Study, a longitudinal population study in Norway. Leisure time physical ...

Objectives: It is known that self-reported health (SRH) declines with increasing age and that comorbidity increases with age. We wished to examine how age transfers its effect to SRH through comorbid disease and mental illness and whether these processes remained stable from 1994 until 2008. The hypothesis is that ageing and/or the increased age-related burden of pathology explains the declining ...

OBJECTIVE: To assess the effect of arm motor impairment on actual arm use in the early post-stroke period and explore its association with self-care dependency. SUBJECTS: Thirty-one patients recruited within the 30 first days after stroke. METHODS: Motor impairment of the upper extremity was measured with Fugl-Meyer Motor Assessment (FMA) and arm use was measured with accelerometry. Arm movement ...

<p><i>SUMMARY</i>: Childhood fracture may predict persistent skeletal fragility, but it may also reflect high physical activity which is beneficial to bone development. We observe a difference in the relationship between previous fracture and bone outcome across physical activity level and sex. Further elaboration on this variation is needed.</p> <p><i>PURPOSE</i>: Childhood fracture may be an ...

<b>Background</b> Grip strength has consistently been found to predict all-cause mortality rates. However, few studies have examined cause-speci fi c mortality or tested age differences in these associations. <b>Methods</b> In 1994, grip strength was measured in the population-based Tromsø Study, covering the ages 50 – 80 years (N=6850). Grip strength was categorised into fi fths, and ...

<p><i>Background</i>: Positive association between body weight and bone mass is well established, and the concept of body mass index (BMI) is associated with higher areal bone mineral density (aBMD) and reduced fracture risk. BMI, that comprises both fat mass (FM) and lean mass (LM) may contribute to peak bone mass achievement in different ways. This study explored the influence of body composition ...

Objective: The scarcity of research on associations between inflammatory markers and symptoms of depression and anxiety during adolescence has yielded inconsistent results. Further, not all studies have controlled for potential confounders. We explored the associations between baseline inflammatory markers and psychological distress including moderators at follow-up in a Norwegian adolescent population ...

<p><i>Summary</i>: Areal bone mineral density (aBMD) predicts future fracture risk. This study explores the development of aBMD and associated factors in Norwegian adolescents. Our results indicate a high degree of tracking of aBMD levels in adolescence. Anthropometric measures and lifestyle factors were associated with deviation from tracking.</p> <p><i>Purpose</i>: Norway has one of the highest ...

Aim: We aim to describe factors that affect self-reported health (SRH) and to describe differences in trajectories in an ageing cohort according to comorbid diseases, mental health, physical condition, education, and physical activity. Methods: Prospective cohort study of a general population in Norway utilizing repeated surveys and physical examinations (1986-2008). We included 16 745 men and ...

<i>Introduction</i>: Vertebral fractures are common osteoporotic fractures, affecting 2–46% of the population, causing morbidity and increased risk of mortality. Physical activity has beneficial effects for bone health, including increased bone mineral density and reduced hip fractures. However, evidence concerning prevention of vertebral fractures is scarce. Therefore, the aim of this study was to ...
