    • Adiposity Without Obesity: Associations with Osteoporosis, Sarcopenia, and Falls in the Healthy Ageing Initiative Cohort Study 

      Scott, David; Johansson, Jonas; Ebeling, Peter R.; Nordström, Peter; Nordström, Anna Hava (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-10-23)
      Objective - Obesity is commonly defined by BMI rather than adiposity, which may have differential effects on musculoskeletal health. Musculoskeletal outcomes were compared in older adults with normal adiposity and normal BMI (NA‐NBMI), those with high adiposity but normal BMI (HA‐NBMI), and those with high adiposity and high BMI (HA‐HBMI).<p> <p>Methods - In 3,411 70‐year‐olds, obesity was defined ...

    • Associations of accelerometer-determined physical activity and sedentary behavior with sarcopenia and incident falls over 12 months in community-dwelling Swedish older adults 

      Scott, David; Johansson, Jonas; Gandham, Anoohya; Ebeling, Peter R; Nordström, Peter; Nordström, Anna Hava (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-02-05)
      <i>Objective</i>: To determine associations of accelerometer-determined time and bouts of sedentary behavior, light physical activity (PA) and moderate-to-vigorous PA (MVPA) with sarcopenia and incident falls over 12 months. <p> <p><i>Methods</i>:A total of 3334 Swedish 70-year-olds were assessed for sarcopenia, as defined by the revised definition of the European Working Group on Sarcopenia in ...

    • Associations of Sarcopenia and Its Components with Bone Structure and Incident Falls in Swedish Older Adults 

      Scott, David; Johansson, Jonas; McMillan, Lachlan; Ebeling, Peter R; Nordström, Peter; Nordström, Anna Hava (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-03-21)
      The aim of this study was to compare bone structure parameters and likelihood of falls across European Working Group on Sarcopenia in Older People (EWGSOP2) sarcopenia categories. 3334 Swedish 70-year olds had appendicular lean mass (normalized to height; ALMHt), lumbar spine and total hip areal BMD (aBMD) estimated by dual-energy X-ray absorptiometry. Volumetric BMD (vBMD) and structure at the ...

    • Mid-calf skeletal muscle density and its associations with physical activity, bone health and incident 12-month falls in older adults: The Healthy Ageing Initiative 

      Scott, David; Johansson, Jonas; McMillan, Lachlan; Ebeling, Peter R; Nordström, Anna Hava; Nordström, Peter (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-12-08)
      <i>Background</i> - Lower skeletal muscle density, indicating greater infiltration of adipose tissue into muscles, is associated with higher fracture risk in older adults. We aimed to determine whether mid-calf muscle density is associated with falls risk and bone health in community-dwelling older adults.<p><p> <i>Methods</i> - 2214 community-dwelling men and women who participated in the ...

    • Moderate-to-vigorous physical activity modifies the relationship between sedentary time and sarcopenia: the Tromsø Study 2015–2016 

      Johansson, Jonas; Morseth, Bente; Scott, David; Strand, Bjørn Heine; Hopstock, Laila Arnesdatter; Grimsgaard, Sameline (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 ...
