    • The association between age at menarche and chronic pain outcomes in women: the Tromsø Study, 2007 to 2016 

      Lund, Charlotte I.; Engdahl, Bo Lars; Rosseland, Leiv Arne; Stubhaug, Audun; Grimnes, Guri; Furberg, Anne-Sofie; Steingrímsdóttir, Ólöf Anna; Nielsen, Christopher Sivert (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-03-01)
      Sex differences in chronic pain are well established with documented predominance in women. This study assessed relationships between age at menarche and chronic pain, site-specific chronic pain, pain characteristics, and chronic widespread pain (CWP). We used data from the Tromsø Study conducted in 2007 to 2008 and 2015 to 2016 (Tromsø 6 and Tromsø 7 waves) including participants aged 30 to 99 ...
    • A population-based study of inflammatory mechanisms and pain sensitivity 

      Schistad, Ellina Iordanova; Kong, Xiang Yi; Furberg, Anne-Sofie; Bäckryd, Emmanuel; Grimnes, Guri; Emaus, Nina; Rosseland, Leiv Arne; Gordh, Torsten; Stubhaug, Audun; Engdahl, Bo Lars; Halvorsen, Bente Evy; Nielsen, Christopher Sivert (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-10-21)
      Two recent studies suggest that experimental pain sensitivity is associated with low-grade systemic inflammation. However, only 2 biomarkers have been identified, and the studies were conducted in adult individuals where confounding effects of comorbid diseases cannot be excluded. We therefore tested associations between pain sensitivity and 119 inflammation-related serum biomarkers in 827 healthy ...
    • Reduced heart rate variability is related to the number of metabolic syndrome components and manifest diabetes in the sixth Tromsø study 2007–2008 

      Azulay, Naomi; Bjørkholt Olsen, Roy; Nielsen, Christopher Sivert; Stubhaug, Audun; Jenssen, Trond Geir; Schirmer, Henrik; Frigessi, Arnoldo; Rosseland, Leiv Arne; Tronstad, Christian (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-07-14)
      Both diabetes mellitus (DM) and the metabolic syndrome (MetS) are associated with autonomic neuropathy, which predisposes to cardiac events and death. Measures of heart rate variability (HRV) can be used to monitor the activity of the autonomic nervous system (ANS), and there are strong indications that HRV can be used to study the progression of ANS-related diabetes complications. This study ...
