    • Effectiveness of a fourth dose of mRNA COVID-19 vaccine against all-cause mortality in long-term care facility residents and in the oldest old: A nationwide, retrospective cohort study in Sweden 

      Nordström, Peter; Ballin, Marcel; Nordström, Anna (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-07-13)
      <p><b> Background:</b> The effect of a fourth dose of COVID-19 vaccine on the risk of death in the oldest and frailest individuals is unknown. <p><b> Methods</b> Two matched cohorts were formed using Swedish nationwide registers. In the first, residents of long-term care facilities (LTCFs) given a fourth dose of an mRNA vaccine from 1 January 2022 onwards were matched 1:1 on birth year and ...

    • Effects of Resistance Training on Functional Strength and Muscle Mass in 70-Year-Old Individuals With Pre-sarcopenia: A Randomized Controlled Trial. 

      Vikberg, Sanna; Sörlén, Niklas; Brandén, Lisa; Johansson, Jonas; Nordström, Anna; Hult, Andreas; Nordström, Peter (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-11-07)
      <i>Objective</i> - Sarcopenia has been defined as age-related loss of muscle mass and function. The aim of this randomized controlled trial was to examine the effects of a 10-week instructor-led resistance training program on functional strength and body composition in men and women aged 70 years with pre-sarcopenia.<p> <p><i>Design, Setting, and Participants</i> - Participants were randomized ...

    • A multiple risk factor program is associated with decreased risk of cardiovascular disease in 70-year-olds: A cohort study from Sweden 

      Nordström, Anna; Bergman, Jonathan; Björk, Sabine; Carlberg, Bo; Johansson, Jonas; Hult, Andreas; Nordström, Peter (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-06-11)
      <i>Background</i> - In individuals below 65 years of age, primary prevention programs have not been successful in reducing the risk of cardiovascular disease (CVD) and death. However, no large study to our knowledge has previously evaluated the effects of prevention programs in individuals aged 65 years or older. The present cohort study evaluated the risk of CVD in a primary prevention program for ...

    • Physical activity levels in adults and elderly from triaxial and uniaxial accelerometry. The Tromsø Study 

      Sagelv, Edvard Hamnvik; Ekelund, Ulf; Pedersen, Sigurd; Brage, Søren; Hansen, Bjørge Hermann; Johansson, Jonas; Grimsgaard, Sameline; Nordström, Anna; Horsch, Alexander; Hopstock, Laila Arnesdatter; Morseth, Bente (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-12-03)
      <i>Introduction</i> - Surveillance of physical activity at the population level increases the knowledge on levels and trends of physical activity, which may support public health initiatives to promote physical activity. Physical activity assessed by accelerometry is challenged by varying data processing procedures, which influences the outcome. We aimed to describe the levels and prevalence estimates ...

    • Short-term balance training and acute effects on postural sway in balance-deficient older adults: a randomized controlled trial 

      Sörlén, Niklas; Hult, Andreas; Nordström, Peter; Nordström, Anna; Johansson, Jonas (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-09)
      <p>Background: We aimed to determine the effectiveness of 4 weeks of balance exercise compared with no intervention on objectively measured postural sway. <p>Methods: This was a single-center parallel randomized controlled, open label, trial. A six-sided dice was used for allocation at a 1:1-ratio between exercise and control. The trial was performed at a university hospital clinic in Sweden and ...

    • Time-varying risk of death after SARS-CoV-2 infection in Swedish long-term care facility residents: a matched cohort study 

      Ballin, Marcel; Ioannidis, John P.; Bergman, Jonathan; Kivipelto, Miia; Nordström, Anna; Nordström, Peter (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-11-24)
      Objectives - To evaluate whether SARS-CoV-2 infection in residents of long-term care (LTC) facilities is associated with higher mortality after the acute phase of infection, and to estimate survival in uninfected residents.<p> <p>Design - Extended follow-up of a previous, propensity score-matched, retrospective cohort study based on the Swedish Senior Alert register.<p> <p>Setting - LTC ...

    • Trends in Hip Fracture Incidence, Length of Hospital Stay, and 30-Day Mortality in Sweden from 1998–2017: A Nationwide Cohort Study 

      Nordström, Peter; Bergman, Jonathan; Ballin, Marcel; Nordström, Anna (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-02-15)
      In this nationwide cohort study, we investigated trends in hip fracture incidence, hospital length of stay (LOS), and 30-day mortality after admission in Sweden. The cohort included all individuals in Sweden aged ≥ 50 years with a first hip fracture diagnosis during 1998–2017 (N = 313,761). The outcomes were hip fracture incidence and 30-day mortality. The results showed that the incidence of hip ...
