Anthropometric measures are satisfactory substitutes for the DXA‐derived visceral adipose tissue in the association with cardiometabolic risk—The Tromsø Study 2015–2016
Lundblad, Marie Wasmuth; Jacobsen, Bjarne Koster; Johansson, Jonas; Grimsgaard, Sameline; Andersen, Lene Frost; Hopstock, Laila Arnesdatter (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-05-03)Background - Body mass index (BMI) increases while cardiometabolic risk factors decrease in individuals in high-income countries. This paradoxical observation raises the question of whether current measures of overweight and obesity properly identify cardiometabolic risk.<p> <p>Methods - A total of 3675 participants (59% women) aged 40–84 years with whole-body dual-energy x-ray absorptiometry ... -
Changes in body mass index and the prevalence of obesity during 1994–2008: repeated cross-sectional surveys and longitudinal analyses. The Tromsø Study
Jacobsen, Bjarne Koster; Aars, Nils Abel (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-06-12)Objectives: To determine the mean body mass index (BMI, kg/m2 ) and prevalence of low weight (BMI<20) and obesity (BMI≥30) in 3 population-based surveys, and to describe the longitudinal changes during 1994– 2008 in mean BMI, and the prevalence of low weight and obesity. Setting: A population study in Tromsø, Norway. Participants: A total of 29 688 different participants in 1 or more of 3 ... -
Energy and nutrient intakes in relation to National Nutrition Recommendations in a Norwegian population-based sample: the Tromsø Study 2015–16
Lundblad, Marie Wasmuth; Andersen, Lene Frost; Jacobsen, Bjarne Koster; Carlsen, Monica Hauger; Hjartåker, Anette; Grimsgaard, Sameline; Hopstock, Laila Arnesdatter (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-12-10)<i>Introduction</i>: According to the Global Burden of Disease project, unhealthy diet accounts for most of the disease burden in Norway. Current recommendations on nutrient intake in Norway reflect those published in the evidence-based Nordic Nutrition Recommendations from 2012 (NNR2012).<p> <p><i>Aim</i>: To study energy and nutrient intakes and compliance with the NNR2012 among women and men ... -
Longitudinal changes in body composition and waist circumference by self-reported levels of physical activity in leisure among adolescents: the Tromsø Study, Fit Futures
Aars, Nils Abel; Jacobsen, Bjarne Koster; Morseth, Bente; Emaus, Nina; Grimsgaard, Sameline (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-12-17)<p><i>Background - </i>It is not clear how physical activity affects body composition in adolescents. Physical activity levels are often reduced during this period, and the relative proportion of body fat mass and lean mass undergo natural changes in growing adolescents. We aimed to examine whether self-reported physical activity in leisure time at baseline or change in activity during follow-up ... -
Non‑linear associations between healthy Nordic foods and all‑cause mortality in the NOWAC study: a prospective study
Jensen, Torill Miriam Enget; Braaten, Tonje Bjørndal; Jacobsen, Bjarne Koster; Skeie, Guri (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-01-25)Background: The shape of the associations between intake of foods basic in a healthy Nordic diet and long-term health is not well known. Therefore, we have examined all-cause mortality in a large, prospective cohort of women in Norway in relation to intake of: Nordic fruits and vegetables, fatty fsh, lean fsh, wholegrain products, and low-fat dairy products.<p> <p>Methods: A total of 83 669 women ... -
Prevalence of general and abdominal obesity in 2015–2016 and 8-year longitudinal weight and waist circumference changes in adults and elderly: the Tromsø Study
Løvsletten, Ola; Jacobsen, Bjarne Koster; Grimsgaard, Sameline; Njølstad, Inger; Wilsgaard, Tom; Løchen, Maja-Lisa; Eggen, Anne Elise; Hopstock, Laila Arnesdatter (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-11-05)<i>Objectives</i> - To describe the prevalence of general (body mass index (BMI) ≥30 kg/m2) and abdominal (waist circumference women >88 cm, men >102 cm) obesity in Tromsø 7 (2015–2016), and the secular change from Tromsø 6 (2007–2008). Furthermore, to study longitudinal changes in body weight and waist circumference from Tromsø 6 to Tromsø 7.<p> <p><i>Setting</i> - A population study in Tromsø, ... -
Reference Values for DXA-Derived Visceral Adipose Tissue in Adults 40 Years and Older from a European Population: The Tromsø Study 2015–2016
Lundblad, Marie Wasmuth; Jacobsen, Bjarne Koster; Johansson, Jonas; de Lucia Rolfe, Emanuella; Grimsgaard, Sameline; Hopstock, Laila Arnesdatter (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-05-17)Background. Reference values for visceral adipose tissue (VAT) are needed and it has been advocated that body composition measures depend on both the technique and methods applied, as well as the population of interest. We aimed to develop reference values for VAT in absolute grams (VATg), percent (VAT%), and as a kilogram-per-meters-squared index (VATindex) for women and men, and investigate potential ... -

Secular and longitudinal trends in body composition: The Tromsø Study, 2001 to 2016
Lundblad, Marie Wasmuth; Johansson, Jonas; Jacobsen, Bjarne Koster; Grimsgaard, Sameline; Andersen, Lene Frost; Wilsgaard, Tom; Hopstock, Laila Arnesdatter (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-09-14)<p><i>Objective - </i>Overweight, defined as excessive fat mass, is a long-standing worldwide public health challenge. Traditional anthropometric measures used to identify overweight and obesity do not assess body composition. The aim of this study was to examine population trends in general and abdominal fat mass during the past two decades. <p><i>Methods - </i>This study included participants ...
