The association of grip strength from midlife onwards with all-cause and cause-specific mortality over 17 years of follow-up in the Tromsø Study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-08-25)<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 ... -
Between-study differences in grip strength: a comparison of Norwegian and Russian adults aged 40-69 years
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-10-03)Background - Identifying individuals with low grip strength is an initial step in many operational definitions of sarcopenia. As evidence indicates that contemporaneous Russian populations may have lower mean levels of grip strength than other populations in northern Europe, we aimed to: compare grip strength in Russian and Norwegian populations by age and sex; investigate whether height, body mass ... -

Comparing associations of handgrip strength and chair stand performance with all-cause mortality—implications for defining probable sarcopenia: the Tromsø Study 2015–2020
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-11-20)Background Widely adopted criteria suggest using either low handgrip strength or poor chair stand performance to identify probable sarcopenia. However, there are limited direct comparisons of these measures in relation to important clinical endpoints. We aimed to compare associations between these two measures of probable sarcopenia and all-cause mortality. <p><p>Methods Analyses included 7838 ... -
Consistent pattern between physical activity measures and chronic pain levels: the Tromsø Study 2015-2016
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-09-08)Epidemiological literature on the relationship between physical activity and chronic pain is scarce and inconsistent. Hence, our aim was to assess the relationship applying comprehensive methodology, including self-reported and accelerometer measures of physical activity and different severity levels of chronic pain.

Fish intake and pre-frailty in Norwegian older adults - a prospective cohort study: the Tromsø Study 1994–2016
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-07-05)Background Pre-frailty is an intermediate, potentially reversible state before the onset of frailty. Healthy dietary choices may prevent pre-frailty. Fish is included in most healthy diets, but little is known about the association between long-term habitual fish intake and pre-frailty. We aimed to elucidate the longitudinal association between the frequency of fish intake and pre-frailty in a ... -

Leisure Time Physical Activities’ Association With Cognition and Dementia: A 19 Years’ Life Course Study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-06-15)Introduction: Cognitive impairment is one of the main disabilities in dementia. Physical activity (PA) has been suggested as protective for dementia. However, the findings are disparate in studies, and the question of whether this is because of reverse causality is still open. We aimed to explore the association of PA with cognition in people who later developed dementia compared to those who ... -
Longitudinal relationships between habitual physical activity and pain tolerance in the general population
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-05-24)Physical activity (PA) might influence the risk or progression of chronic pain through pain tolerance. Hence, we aimed to assess whether habitual leisure-time PA level and PA change affects pain tolerance longitudinally in the population. Our sample (n = 10,732; 51% women) was gathered from the sixth (Tromsø6, 2007–08) and seventh (Tromsø7, 2015–16) waves of the prospective population-based Tromsø ... -

(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-01-10)Background: Disability in older adults is associated with loss of independence, institutionalization, and death. The aim of this study was to study the association between the Timed Up and Go (TUG) test and all-cause mortality in a population-based sample of older men and women. <p> Methods: Our study population was home dwellers aged 65 and above, who participated in the fifth wave of the Tromsø ... -
Moderate-to-vigorous physical activity modifies the relationship between sedentary time and sarcopenia: the Tromsø Study 2015–2016
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-06-01)<p>Background: Sarcopenia is an age-related muscle disease primarily characterized by reductions in muscle strength that increases the risk of falls, fractures, cognitive impairment, and mortality. Exercise is currently preferred in prevention and treatment, but it is unknown how different habitual physical activity and sedentary behaviour patterns associate with sarcopenia status. The purpose of ... -

Physical capability, physical activity, and their association with femoral bone mineral density in adults aged 40 years and older: The Tromsø study 2015–2016
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-04-16)Summary: Since muscles can influence bone growth and vice versa, we examined if level of physical activity and physical capability tests can predict areal bone mineral density (aBMD). Both high activity level and good test performance were associated with higher aBMD, especially in women. <p> <p>Introduction: Muscle influences bone formation and vice versa. Tests of physical capability and level ...
