    • Changes in adiposity, physical activity, cardiometabolic risk factors, diet, physical capacity and well-being in inactive women and men aged 57-74 years with obesity and cardiovascular risk – A 6-month complex lifestyle intervention with 6-month follow-up 

      Hopstock, Laila Arnesdatter; Deraas, Trygve Sigvart; Henriksen, André; Martiny-Huenger, Torsten; Grimsgaard, Sameline (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-08-25)
      A key challenge in lifestyle interventions is long-term maintenance of favorable lifestyle changes. Middle-aged and older adults are important target groups. The purpose of this analysis was to investigate changes in adiposity, physical activity, cardiometabolic risk factors, diet, physical capacity, and well-being, in inactive middle-aged and older women and men with obesity and elevated cardiovascular ...

      Fjeld, Mats Kirkeby; Årnes, Anders; Engdahl, Bo Lars; Morseth, Bente; Hopstock, Laila Arnesdatter; Horsch, Alexander; Stubhaug, Audun; Strand, Bjørn Heine; Nielsen, Christopher Sivert; Steingrímsdóttir, Ólöf Anna (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. We used data from the Tromsø Study (2015-2016). All residents in the municipality, ...
    • Consumer-Based Activity Trackers as a Tool for Physical Activity Monitoring in Epidemiological Studies During the COVID-19 Pandemic: Development and Usability Study 

      Henriksen, André; Johannessen, Erlend; Hartvigsen, Gunnar; Grimsgaard, Sameline; Hopstock, Laila Arnesdatter (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-04-23)
      Background: Consumer-based physical activity trackers have increased in popularity. The widespread use of these devices and the long-term nature of the recorded data provides a valuable source of physical activity data for epidemiological research. The challenges include the large heterogeneity between activity tracker models in terms of available data types, the accuracy of recorded data, and how ...
    • Criterion validity of two physical activity and one sedentary time questionnaire against accelerometry in a large cohort of adults and older adults

    • Cross-sectional associations between accelerometry-measured physical activity, left atrial size, and indices of left ventricular diastolic dysfunction: The Tromsø Study 

      Heitmann, Kim Arne; Løchen, Maja-Lisa; Hopstock, Laila Arnesdatter; Stylidis, Michael; Welde, Boye; Schirmer, Henrik; Morseth, Bente (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-12-31)
      Whereas left atrial (LA) enlargement is an independent predictor for adverse cardiovascular events and all-cause mortality, this is regarded a physiological adaption of exercise. Paradoxically, LA size in athletes may overlap the enlargement observed in patients with cardiac pathology. Current knowledge is mainly derived from studies of athletes, and little is known about cardiac adaptations to ...

      <p><i>Background - </i>The relationship between high sensitivity C-reactive protein and migraine is unclear. The aim of this cross-sectional population-based study was to investigate the association between high sensitivity C-reactive protein and types of headache, and to evaluate the impact of insomnia on this association. <p><i>Methods - </i>A total of 20,486 (63%) out of 32,591 invited, aged ≥40 ...
    • Dual-Energy X-Ray Absorptiometry Derived Adiposity Measures and Pre-Frailty/Frailty among Norwegian Adults: The Tromsø Study 2007–2015 

      Uchai, Shreeshti; Andersen, Lene Frost; Johansson, Jonas; Hopstock, Laila Arnesdatter; Hjartåker, Anette (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-05-25)
      OBJECTIVES: Aging is associated with changes in body composition. Excess adiposity among older adults has been linked with metabolic syndromes and aggravated age-associated decline in physical functioning. Few longitudinal studies have explored the association between dual-energy X-ray absorptiometry (DXA)-derived total as well as central adiposity measures and frailty. We examined the association ...

      Worldwide, there are socioeconomic inequalities in health and diet. We studied the relationship between education and nutrient intake in 11,302 women and men aged 40–96 years who participated in the seventh survey of the population-based Tromsø Study (2015–2016), Norway (attendance 65%). Diet was assessed using a validated food-frequency questionnaire. We examined the association between education ...
    • Effect of adiposity on differences in carotid plaque burden in studies conducted in Norway and Russia: a cross-sectional analysis of two populations at very different risk of cardiovascular mortality 

      Imahori, Yume; Frost, Chris; Mathiesen, Ellisiv B.; Ryabikov, Andrey; Kudryavtsev, Alexander V; Malyutina, Sofia; Kornev, Michael; Hughes, Alun D; Hopstock, Laila Arnesdatter; Leon, David Adrew (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-05-06)
      <i>Objectives</i> - Large differences exist in the burden of cardiovascular disease (CVD) between Russia and Western European countries including Norway. Obesity prevalence may contribute to the differences. We investigated whether difference in the level of adiposity, assessed using body mass index and waist-to-hip ratio(WHR), could explain intercountry differences in the burden of carotid plaque, ...
