More than Half of High School Students Report Disordered Eating: A Cross Sectional Study among Norwegian Boys and Girls
2015
Disordered eating and eating disorders are of great concern due to their associations with physical and mental health risks. Even if adolescence has been identified as the most vulnerable time for developing disordered eating, few studies have used a broad spectrum of criteria to investigate the prevalence of disordered eating among high school students of both genders, in different programs of study, nor assessed correlates of disordered eating among this important target group. The purposes of this study were therefore to investigate the prevalence and correlates of disordered eating among both male and female high school students in sport-, general and vocational programs.

The association between time scarcity, sociodemographic correlates and consumption of ultra-processed foods among parents in Norway: a cross-sectiona…
2017
Background Use of ultra-processed foods has expanded rapidly over the last decades and high consumption has been positively associated with risk of e.g. overweight, obesity and type 2 diabetes. Ultra-processed foods offer convenience as they require minimal time for preparation. It is therefore reasonable to assume that such foods are consumed more often among people who experience time scarcity. The main aim of this study was to investigate the association between time scarcity and consumption of ultra-processed foods among parents of 2-year olds in Norway. A secondary aim was to investigate the association between sociodemographic correlates, weight status and consumption of ultra-process…

Furthermore, knowledge about weight perceptions and the relationship to food behaviour among young men is scant. The purpose of this study was to explore the relationship between BMI, health and weight perceptions and food intake patterns among young men in the military. Methods Data were collected with a 4-day food diary among 578 male recruits (age 18-26, mean 19.7) in the Norwegian National Guard (response rate 78%), in addition to a questionnaire, including questions about health and weight perceptions, and food frequency when still li…
Creatine as a Promising Component of Paternal Preconception Diet
2022
Male fertility has been declining globally over the past several decades, advancing from a personal issue to a public health problem. Beyond any doubt, a reduction in fertility (often characterized by low sperm count or motility) can severely threaten reproductive health and lifecourse framework in a long-term fashion. Aside from uncovering the currently unknown etiology of modern-day male infertility, the scientific and medical community faces a double burden: finding an efficient biomarker of impaired fertility and exploring any intervention that can act to enhance fertility. A plethora of nutritional compounds have been recognized as possible modulators of semen quality, and specific die…

The association between adherence to the New Nordic Diet and diet quality.
2016
Background : Previous studies have reported a positive association between scoring on healthy Nordic diet scales and the intake of healthy foods and nutrients, and also with higher intake of meat, sweets, cakes, and energy in general. These studies have used the same food frequency questionnaire (FFQ) responses for constructing the diet score as for calculating intakes of foods and nutrients. Thus, it is not clear whether the coexistence of healthy and less healthy dietary aspects among adherers to Nordic diets would occur even though separate methods were applied for exploring these relations. Objective : To assess the association between adherence to the New Nordic Diet (NND), derived fro…

Iron Status of Vegans, Vegetarians and Pescatarians in Norway
2021
Although plant-based diets provide well-established physical and environmental health benefits, omitting meat or meat products has also been associated with a risk of being deficient in specific nutrients, such as iron. As data on the iron status among Norwegian vegans, vegetarians and pescatarians are lacking, the present study aimed to assess iron status in these groups of healthy adults. Blood markers for iron status were measured in 191 participants (18–60 years old) comprising 106 vegans, 54 vegetarians and 31 pescatarians: serum-ferritin (S-Fe), serum-iron (S-Iron) and serum-total iron binding capacity (S-TIBC). Serum-transferrin-saturation (S-TSAT) was estimated (S-Iron/S-TIBC × 100)…

How to evaluate the effect of seven years of the Norwegian School Fruit Scheme (2007-2014) on fruit, vegetable and snack consumption and weight statu…
2019
Aim: From August 2007 to June 2014, the Norwegian School Fruit Scheme (NSFS) legally established that all pupils in junior high and combined schools (275,000 pupils every year), but not those in primary schools (343,000 pupils every year), were entitled to a free piece of fruit or vegetable every school day. The NSFS is a natural experiment, unique in terms of scope and lengthiness. Such governmental efforts to improve the diet of the public are rarely evaluated. Thus, an evaluation of the comprehensive, well-designed NSFS is warranted. The aim was to describe how the NSFS can be evaluated using existing data sets. Methods: Four data sets have been identified for the evaluation of the NSFS…

Abstract The intake of fruit and vegetables is associated with beneficial health outcomes, and studies aimed at increasing fruit and vegetable intake lack long-term follow-up. The primary objective of this study was to evaluate the long-term (14-year) effects of a multicomponent school-based educational intervention targeted to increase fruit and vegetable intake in children. The secondary objective was to evaluate the potential synergistic effect between free school fruit and the educational program. A cluster randomized school-based intervention was initiated in 2001 in Norway, known as the Fruit and Vegetable Make the Marks study. In total, 38 schools were randomized; for the interventio…

Tracking of fruit, vegetables and unhealthy snacks consumption from childhood to adulthood (15 year period): does exposure to a free school fruit pro…
2019
Background The rationale for promoting increased consumption of fruit and vegetables (FV) at an early age is based on results from previous tracking-studies, indicating that dietary habits learned in childhood sustain into adulthood. Previous tracking studies have several limitations (e.g. low study sample, few repeated measurements and/or short a follow-up period). In addition, to our knowledge, no study has shown that a dietary intervention initiated in childhood affects tracking of dietary behaviour. The main objectives in this study were therefore to assess tracking of FV and unhealthy snacks in a large sample with multiple follow-up surveys over 15-years, and whether exposure to free s…
Risk Assessment of "Other Substances" – L-lysine
2020
The Norwegian Scientific Committee for Food Safety (Vitenskapskomiteen for mattrygghet, VKM) has, at the request of the Norwegian Food Safety Authority (Mattilsynet; NFSA), assessed the risk of "other substances" in food supplements and energy drinks sold in Norway. VKM has assessed the risk of doses given by NFSA. These risk assessments will provide NFSA with the scientific basis while regulating "other substances" in food supplements.
 "Other substances" are described in the food supplement directive 2002/46/EC as substances other than vitamins or minerals that have a nutritional and/ or physiological effect. It is added mainly to food supplements, but also to energy drinks and other…

<b><i>Background:</i></b> Data on redox plasma aminothiol status in individuals on strength training are very limited. Therefore, we studied the effect of omega-3 and vitamins E + C supplementation on the concentration of B-vitamins and redox aminothiol status in elderly men after strength training for 3 months. <b><i>Methods:</i></b> Healthy men, age 60 ± 6 (mean ± SD) were randomly divided into 3 groups: group I received placebo (n = 17), group II consumed omega-3 (700 mg, n = 17), and group III consumed vitamins E + C (235 mg +1 g, n = 16) daily for 3 months. All participants completed a strength training program for the same period. <b&…

2015
Background: High quality physical education programs in high schools may facilitate adoption of sustainable healthy living among adolescents. Public health nurses often meet students who avoid taking part in physical education programs. We aimed to explore physical education teachers’ and public health nurses’ perceptions of high school students’ attitudes towards physical education, and to explore physical education teachers’ thoughts about how to facilitate and promote students’ participation in class. Methods: Prior to an initiative from physical education teachers, introducing a new physical education model in two high schools in the South of Norway, we conducted focus groups with 6 phy…

2023
The Norwegian authorities started a nationwide free school fruit program in 2007, implemented in all secondary schools (grades 8–10) and combined schools (grades 1–10) in Norway. The program ended in 2014. This study evaluates the effect of ending the nationwide free school fruit program on the consumption of fruit, vegetables, and unhealthy snacks among Norwegian sixth and seventh graders. The study sample consists of pupils at 18 schools that participated in all data collections in the Fruits and Vegetables Make the Marks project (FVMM), initiated in 2001, with new data collections in 2008 and 2018. Four of the schools were combined schools, therefore children in sixth and seventh grade a…

Risky Lives? Self-Directed Violence and Violence From Others Among Young People Not in Education, Employment, or Training (NEET)
2022
Self-directed violence and violence from others comprise a major public health concern in youth. However, we lack knowledge about the prevalence of violent experiences among young people that are not in education, employment, or training (NEET), whether violent occurrences are similar among girls and boys, and whether violence differs between NEET youths and young students. This cross-sectional study compared the occurrences of self-directed violence (suicide attempts and self-harm) and exposure to violence from others (violent threats, beaten without visible marks, or injured due to violent events) between 96 NEET youth and 384 age- and sex-matched upper secondary school students (16–21 ye…
