      Rad, Amir; Sørbye, Sveinung; Brenn, Tormod; Tiwari, Sweta; Løchen, Maja-Lisa; Skjeldestad, Finn Egil (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-02-25)
      Background: A specific, cost-effective triage test for minor cytological abnormalities is essential for cervical cancer screening among younger women to reduce overmanagement and unnecessary healthcare utilization. We compared the triage performance of one 13-type human papillomavirus (HPV) DNA test and one 5-type HPV mRNA test. Methods: We included 4115 women aged 25–33 years with a screening ...

      Background and purpose:<br>Previous studies have shown associations between atrial fibrillation (AF) and cognitive decline. We investigated this association in a prospective population study, focusing on whether stroke risk factors modulated this association in stroke-free women and men.<br>Methods:<br>We included 4983 participants (57% women) from the fifth survey of the Tromsø Study (Tromsø 5, ...

    • Atrial Fibrillation: A prospective population study of risk factors and complications. The Tromsø Study 

      Tiwari, Sweta (Doctoral thesis; Doktorgradsavhandling, 2018-04-26)
      Background: Atrial Fibrillation (AF) is the most common arrhythmia associated with increased mortality and morbidity. It increases the lifetime risk of stroke and heart failure and affects one’s quality of life and cognition. Objective: To investigate diastolic dysfunction as risk factor for AF and AF as a risk factor for stroke and cognitive decline. Methods: Participants from the Tromsø Study ...

    • CHA2DS2-VASc score, left atrial size and atrial fibrillation as stroke risk factors in the Tromsø Study 

      Tiwari, Sweta; Løchen, Maja-Lisa; Jacobsen, Bjarne K.; Hopstock, Laila Arnesdatter; Nyrnes, Audhild; Njølstad, Inger; Mathiesen, Ellisiv B.; Schirmer, Henrik (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-09-01)
      Objective:<br> CHA2DS2-VASc score, left atrial (LA) size and atrial fibrillation (AF) have individually been associated with stroke risk. Our aim was to investigate the predictive ability of combinations of these factors for the odds of incident stroke in a population-based cohort study.<br> Methods:<br> We followed 2844 participants from the Tromsø Study from 1994 to 2012. Information on LA size ...

    • Epidemiologisk atrieflimmerforskning i Tromsøundersøkelsen. Hva har vi lært? 

      Løchen, Maja-Lisa; Tiwari, Sweta (Journal article; Tidsskriftartikkel; Peer reviewed, 2019)
      Tromsøundersøkelsen er Norges lengste, mest omfattende og best besøkte epidemiologiske befolkningsundersøkelse gjennom mer enn 40 år. Forskningen har gitt oss viktig kunnskap om helse og sykdom og bidrar til bedre pasientbehandling, nasjonalt og internasjonalt. Atrieflimmerforskning har bidratt til ny kunnskap om utbredelse og risikofaktorer.

    • Factors influencing unmet needs for family planning among currently married women in Nepal 

      Tiwari, Sweta (Master thesis; Mastergradsoppgave, 2012-08-01)
      Background: Family planning is one of the most cost-effective interventions available, but still there exists unmet needs for family planning. Women are said to have unmet needs for family planning if they want to stop or delay child bearing, but are not using any methods of contraception. According to Nepal Demographic and Health Survey (NDHS) 2001 data the prevalence of unmet needs in Nepal was ...

    • Lifestyle factors as mediators of area-level socio-economic differentials in cardiovascular disease risk factors. The Tromsø Study 

      Tiwari, Sweta; Cerin, Ester; Wilsgaard, Tom; Løvsletten, Ola; Njølstad, Inger; Grimsgaard, Sameline; Hopstock, Laila Arnesdatter; Schirmer, Henrik; Rosengren, Annika; Kristoffersen, Kathrine; Løchen, Maja-Lisa (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-09-24)
      Introduction: Cardiovascular disease (CVD) is a leading cause of death and disability and living in areas with low socio-economic status (SES) is associated with increased risk of CVD. Lifestyle factors such as smoking, physical inactivity, an unhealthy diet and harmful alcohol use are main risk factors that contribute to other modifiable risk factors, such as hypertension, raised blood cholesterol, ...

    • Lifestyle factors as mediators of area-level socioeconomic differentials in mental health and cognitive function: the Tromsø Study 

      Tiwari, Sweta; Cerin, Ester; Wilsgaard, Tom; Løvsletten, Ola; Grimsgaard, Anne Sameline; Hopstock, Laila Arnesdatter; Schirmer, Henrik; Rosengren, Annika; Kristoffersen, Kathrine; Løchen, Maja-Lisa (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-11-22)
      Introduction - Low socioeconomic status (SES) is associated with poor mental health and cognitive function. Individual-level SES and area-level SES (ASES) may affect mental health and cognitive function through lifestyle. We aimed to quantify the associations of ASES with mental health and cognitive function and examine the mediating role of lifestyle behaviours independent of individual-level SES ...
