Objectives
Aging is associated with changes in body composition. Excess adiposity among older adults has been linked with metabolic syndromes and aggravated age-associated decline in physical functioning. Few longitudinal studies have explored the association between dual-energy X-ray absorptiometry (DXA)-derived total as well as central adiposity measures and frailty. We examined the association of DXA-derived total and central adiposity with pre-frailty/frailty among Norwegian adults after 8 years of follow-up.
Design
Prospective observational study.
Setting
Community-dwelling adults from Tromsø, Norway.
Measurements
Adiposity was defined by fat mass index (FMI) and visceral adipose tissue (VAT) mass assessed using DXA measures. Frailty status was assessed by low grip strength, slow walking speed, exhaustion, unintentional weight loss and low physical activity level. Pre-frail and frail participants at baseline were excluded. Sex-stratified multivariable logistic regression models were used to investigate the association.
Results
Participants comprised 234 women (mean age 68 years) and 146 men (mean age 69 years) attending the population-based Tromsø Study in 2007–2008 (Tromsø6) and 2015–2016 (Tromsø7). At the end of follow-up, 25.6% of the women and 27.4% of the men were pre-frail/frail. Compared with women in the lowest tertiles, those in the highest tertile of baseline FMI (odds ratio [OR] 4.42, 95% confidence interval [CI] 1.88–10.35) and VAT mass (OR 2.47, 95% CI 1.10–5.50), respectively had higher odds for pre-frailty/frailty at follow-up.
Conclusion
We found a higher likelihood of pre-frailty/frailty in later years among women with general and central adiposity in adulthood, highlighting the importance of preventing excess adiposity for healthy aging.

Background: Malnutrition in elderly institutionalized patients is a significant challenge associated with adverse health
outcomes. The ‘MyFood’ decision support system was designed to prevent and treat malnutrition and has previously
been studied in a hospital setting. The aim of this study was to explore the experiences of nursing staff regarding the
implementation of MyFood in settings treating elderly patients.
Methods: The study was conducted in two settings treating elderly patients in Norway. Nursing staff received
training in how to follow-up patients with MyFood. Qualitative interviews were conducted with 12 nursing staff. The
Consolidated Framework for Implementation Research (CFIR) was used to guide the data collection and the thematic
data analysis.
Results: The implementation of a digital decision support system to prevent and treat malnutrition into settings
treating elderly patients was found to be affected by intervention-related, contextual, and personal factors.
Although nursing staff experienced several advantages, the leadership engagement was low and hampered the
implementation.
Conclusion: Nursing staff experienced several advantages with implementing a digital decision support system for
the prevention and treatment of malnutrition in institutionalized elderly patients, including quality improvements and
time savings. The results indicate that the leadership engagement was weak and that some nursing staff experienced
low self-efficacy in digital competence. Future improvements include increasing the level of training, using MyFood
throughout the patient course and involving the patient’s next-of-kin.

In mammals, trait variation is often reported to be greater among males than females. However, to date, mainly only morphological traits have been studied. Energy expenditure represents the metabolic costs of multiple physical, physiological, and behavioral traits. Energy expenditure could exhibit particularly high greater male variation through a cumulative effect if those traits mostly exhibit greater male variation, or a lack of greater male variation if many of them do not. Sex differences in energy expenditure variation have been little explored. We analyzed a large database on energy expenditure in adult humans (1494 males and 3108 females) to investigate whether humans have evolved sex differences in the degree of interindividual variation in energy expenditure. We found that, even when statistically comparing males and females of the same age, height, and body composition, there is much more variation in total, activity, and basal energy expenditure among males. However, with aging, variation in total energy expenditure decreases, and because this happens more rapidly in males, the magnitude of greater male variation, though still large, is attenuated in older age groups. Considerably greater male variation in both total and activity energy expenditure could be explained by greater male variation in levels of daily activity. The considerably greater male variation in basal energy expenditure is remarkable and may be explained, at least in part, by greater male variation in the size of energy-demanding organs. If energy expenditure is a trait that is of indirect interest to females when choosing a sexual partner, this would suggest that energy expenditure is under sexual selection. However, we present a novel energetics model demonstrating that it is also possible that females have been under stabilizing selection pressure for an intermediate basal energy expenditure to maximize energy available for reproduction.

Young children have unique nutritional requirements, and breastfeeding is the best option to support healthy growth and development. Concerns have been raised around the increasing use of milk-based infant formulas in replacement of breastfeeding, in regards to health, social, economic and environmental factors. However, literature on the environmental impact of infant formula feeding and breastfeeding is scarce. In this study we estimated the environmental impact of four months exclusive feeding with infant formula compared to four months exclusive breastfeeding in a Norwegian setting. We used life-cycle assessment (LCA) methodology, including the impact categories global warming potential, terrestrial acidification, marine and freshwater eutrophication, and land use. We found that the environmental impact of four months exclusive feeding with infant formula was 35–72% higher than that of four months exclusive breastfeeding, depending on the impact category. For infant formula, cow milk was the main contributor to total score for all impact categories. The environmental impact of breastfeeding was dependant on the composition of the lactating mother’s diet. In conclusion, we found that breastfeeding has a lower environmental impact than feeding with infant formula. A limitation of the study is the use of secondary LCA data for raw ingredients and processes.

Low total energy expenditure (TEE, MJ/d) has been a hypothesized risk factor for weight gain, but repeatability of TEE, a critical variable in longitudinal studies of energy balance, is understudied. We examine repeated doubly labeled water (DLW) measurements of TEE in 348 adults and 47 children from the IAEA DLW Database (mean ± SD time interval: 1.9 ± 2.9 y) to assess repeatability of TEE, and to examine if TEE adjusted for age, sex, fat-free mass, and fat mass is associated with changes in weight or body composition. Here, we report that repeatability of TEE is high for adults, but not children. Bivariate Bayesian mixed models show no among or within-individual correlation between body composition (fat mass or percentage) and unadjusted TEE in adults. For adults aged 20–60 y (N = 267; time interval: 7.4 ± 12.2 weeks), increases in adjusted TEE are associated with weight gain but not with changes in body composition; results are similar for subjects with intervals >4 weeks (N = 53; 29.1 ± 12.8 weeks). This suggests low TEE is not a risk factor for, and high TEE is not protective against, weight or body fat gain over the time intervals tested.

Studies exploring mediators of socioeconomic inequalities in excess weight gain in early-life and subsequent overweight/obesity (OW/OB) among youth are limited. Thus, this study examined the mediating role of prenatal and early postnatal factors and child energy balance-related behaviours (EBRB) in the effects of parental education on (i) excess weight gain from birth to 2 years and (ii) OW/OB at 5, 8 and 14 years. The Norwegian Mother, Father and Child Cohort Study was used to include participants at the ages of 2 (n = 59,597), 5 (n = 27,134), 8 (n = 28,285) and 14 (n = 11,278) years. Causal mediation analyses using the inverse odds weighting approach were conducted. Children of low-educated parents had a higher conditional excess weight gain at 2 years compared to children of high-educated parents (total effect, RRTE = 1.06; 95% CI 1.01, 1.10). The joint mediation effects of the prenatal and early postnatal factors explained most of the total effect of low education on conditional excess weight gain at 2 years. Children of low-educated parents had a higher risk of OW/OB at 5, 8 and 14 years compared to children of high-educated parents. The mediators jointly explained 63.7%, 67% and 88.9% of the total effect of parental education on OW/OB among 5, 8 and 14 year-old-children, respectively. Of the total mediated effects at 5, 8 and 14 years, the prenatal and early postnatal mediators explained 59.2%, 61.7% and 73.7%, whereas the child EBRB explained 10.3%, 15.8.0%% and 34.8%. The mediators included were found to have a considerable mediating effect in the associations explored, in particular the prenatal and early postnatal factors. If truly causal, the findings could indicate potential targets for interventions to tackle socioeconomic inequalities in OW/OB from birth to adolescence.

Background
Protein intake is suggested as an important dietary factor in the prevention of frailty, however, the influence of lifelong intake remains unclear.
Objectives
The present study investigated the relationship between daily protein intake and patterns of protein intake over 21 years and the risk of pre-frailty/frailty.
Design
Prospective cohort study.
Setting
The population-based Tromsø Study in Tromsø municipality, Norway.
Participants
In total, 1,906 women and 1,820 men aged ≥45 years in 1994 who participated in both Tromsø4 (1994–95) and Tromsø7 (2015–16).
Measurements
Frailty status in Tromsø7 was measured according to Fried’s phenotype, classifying participants as “robust” (frailty components present: 0), “pre-frail” (1–2) or “frail” (≥3). Daily intake of protein was estimated from self-reported habitual dietary intake using food frequency questionnaires and assessed as grams per kilogram bodyweight (g/kg BW) and per megajoule energy intake (g/MJ). The protein–frailty association was assessed via longitudinal and cross-sectional multivariable logistic regression analyses.
Results
The prevalence of pre-frailty and frailty in this study was 27% and 1.0%, respectively. Longitudinal analysis showed that the odds of pre-frailty/frailty decreased by 57% (odds ratio (OR) = 0.43, 95% confidence interval (CI) = 0.31;0.58, p<0.001) with the increase in intake of one additional gram of dietary protein per kg BW. The results obtained from cross-sectional analysis were similar. Tracking analysis showed that, compared to a stable high intake of protein in g/kg BW over time, other patterns of protein intake increased the risk of pre-frailty/frailty. No associations were found between intake of protein in g/MJ and pre-frailty/frailty.
Conclusions
Intake of protein in g/kg BW both in mid-life and later in life was inversely associated with pre-frailty/frailty in older adults. This emphasizes the importance of an adequate protein intake to facilitate healthy ageing in Norwegian older adults.

Background and aims
Diet may alter gene expression in immune cells involved in atherosclerotic cardiovascular disease susceptibility. However, we still lack a robust understanding of the association between diet and immune cell-related gene expression in humans. Therefore, we examined associations between dietary patterns (DPs) and gene expression profiles in peripheral blood mononuclear cells (PBMCs) in a population of healthy, Norwegian adults (n = 130 women and 105 men).
Methods and results
We used factor analysis to define a posteriori DPs from food frequency questionnaire-based dietary assessment data. In addition, we derived interpretable features from microarray-based gene expression data (13 967 transcripts) using two algorithms: CIBERSORT for estimation of cell subtype proportions, and weighted gene co-expression network analysis (WGCNA) for cluster discovery. Finally, we associated DPs with either CIBERSORT-predicted PBMC leukocyte distribution or WGCNA gene clusters using linear regression models. We detected three DPs that broadly reflected Western, Vegetarian, and Low carbohydrate diets. CIBERSORT-predicted percentage of monocytes associated negatively with the Vegetarian DP. For women, the Vegetarian DP associated with a large gene cluster consisting of 600 genes mainly involved in regulation of DNA transcription, whereas for men, the Western DP inversely associated with a smaller cluster of 36 genes mainly involved in regulation of metabolic and inflammatory processes. A subsequent protein–protein interaction network analysis suggested that genes within these clusters might physically interact in biological networks.
Conclusions
Although the present findings are exploratory, our analysis pipeline serves as a useful framework for studying the association between diet and gene expression.

OBJECTIVE:
To report on long-term effects of a cluster randomized controlled kindergarten-based intervention trial, which aimed to increase vegetable intake among Norwegian preschool children (3-5 years at baseline). The effects of the intervention at follow-up 1 (immediately post-intervention) have previously been published. This paper presents the effects of the intervention from baseline to follow-up 2 (12 months post-intervention).
RESULTS:
Parental consents were obtained for 633 out of 1631 eligible children (response rate 38.8%). The effects of the intervention from baseline to follow-up 2 were assessed by mixed-model analyses taking the clustering effect of kindergartens into account. Children's vegetable intake was reported by the parents at baseline (spring 2015), at follow-up 1 (spring 2016) and at follow-up 2 (spring 2017). No significant long-term effects in child vegetable intake were found. A mean difference of - 0.1 times per day (95% CI - 0.5, 0.2) (P = 0.44) was found for the daily frequency of vegetable intake. A mean difference of - 0.2 different kinds of vegetables eaten over a month (95% CI - 1.0, 0.7) (P = 0.70) was found and for daily amount of vegetables a mean difference of - 15.0 g vegetables (95% CI - 38.0, 8.0) (P = 0.19) was found.

Abstract
BACKGROUND:
Iodine is crucial for normal growth and neurodevelopment. Before 1950, goitre caused by iodine deficiency was widespread in Norway, but decreased significantly after mandatory fortification of animal fodder. Recent dietary changes in milk consumption and fish intake may again have increased the risk of inadequate intakes in some population groups in Norway. The situation for children and adolescents is unclear, and data from nationally representative studies are highly needed. We aimed to describe the iodine intake in Norwegian children and adolescents and estimate the proportion of individuals with an increased risk of suboptimal, adequate and excessive usual iodine intake. In addition, we aimed to investigate whether individuals' characteristics were associated with iodine intake, and to identify the major iodine contributing foods in the diet of this population.
METHODS:
Data from 1722 individuals (4-, 9- and 13-year-olds) from a national dietary survey in Norway from 2015-2016 was used. Both descriptive and inferential statistics were conducted. Usual iodine intakes were estimated, stratified by age group and sex and compared to dietary reference intake cut-offs. Linear regression models were used to assess the association between iodine intake and participants' characteristics. The contribution of iodine from different foods was described for all and across different participant groups.
RESULTS:
We estimated that the proportion of participants with an increased risk of a suboptimal usual intake of iodine varied from 3-36%. A significant increased risk was observed for older children and girls compared to younger children and boys. Excessive usual intakes were not observed in any age group. Iodine intake was associated with sex, maternal educational level and area of residence. A lower intake was observed for girls and those with a mother with a low educational level. Moreover, those living in the western part and Mid-Norway had statistically significantly higher intakes compared to those living in the capital city and surroundings. Milk, milk products, cheese, fish and shellfish were the main contributors to iodine intake. Supplements contributed with very little of the total iodine intake.
CONCLUSIONS:
We have shown that the estimated risk of suboptimal usual iodine intakes among children and adolescents in Norway varies according to age, sex, maternal educational level and area of residence. Those with a limited intake of the main dietary contributors to iodine intake may be at risk, and adolescent girls seem to be especially vulnerable.

Background: Early childhood represents a critical period for the establishment of long-lasting healthy dietary
habits. Limited knowledge exists on how to successfully increase vegetable consumption among preschool
children. The overall aim of the present study was to improve vegetable intake among preschool children in a
kindergarten-based randomized controlled trial.
Methods: The target group was preschool children born in 2010 and 2011, attending public or private
kindergartens in two counties in Norway. Data about child intake of vegetables were collected by three methods.
First, parents filled in a web-based questionnaire of the child’s vegetable intake. Second, among a subsample,
trained researchers observed children’s vegetable intake in the kindergarten. Thirdly, a parental web-based 24-h
recall assessing the child’s vegetable intake was filled in. For allocation of kindergartens to intervention and control
groups, a stratified block randomization was used. Multiple intervention components were implemented from
September 2015 to February 2016 and components focused at influencing the four determinants availability,
accessibility, encouragement and role modelling. The effect of the intervention from baseline (spring 2015) to
follow-up 1 (spring 2016) was assessed by mixed-model analysis taking the clustering effect of kindergartens into
account.
Results: Parental consent was obtained for 38.8% of the children (633 out of 1631 eligible children). Based on the
observational data in the kindergarten setting (n 218 in the control group and n 217 in the intervention group), a
tendency to a small positive effect was seen as a mean difference of 13.3 g vegetables/day (95% CI: − 0.2, 26.9) (P =
0.054) was observed.
No significant overall effects were found for the total daily vegetable intake or for the parental reported frequency
or variety in vegetable intake.
Conclusions: Based on the observational data in the kindergarten setting, a tendency to a small positive effect was
seen with a mean difference of about 13 g vegetables/day, while no other effects on child vegetable intake were
found. Additionally, further research to understand the best strategies to involve parents in dietary interventions studies is warranted.

Aim: Elevated total cholesterol (TC) and glycated hemoglobin (HbA1c) are risk factors for cardiovascular disease however little is known about their determinants in infants. We aimed to describe TC and HbA1c concentrations in infants aged 8-14 months, and explore the relation between infant TC, HbA1c, breastfeeding, infant diet, and maternal TC and HbA1c.
Methods: In this cross-sectional pilot study, mothers of infants aged 6 and 12 months were invited to complete a food frequency questionnaire and to take home-based dried blood spot samples from themselves and their infants.
Results: Among the 143 included infants, the mean (SD, range) concentration was 4.1 (0.8, 2.3-6.6) mmol/L for TC and 4.9 (0.4, 3.7-6.0) % for HbA1c. There was no significant difference between age groups or sexes. There was a positive relation between TC concentrations of all infants and mothers (B=0.30 unadjusted, B=0.32 adjusted, P<0.001 for both), and a negative relation between infant TC and intake of unsaturated fatty acids in the oldest age group (B=-0.09, P=0.03 unadjusted, B=-0.08, P=0.06 adjusted). Infant HbA1c was not significantly related to diet or maternal HbA1c.
Conclusion: TC and HbA1c concentrations varied widely among infants aged 8-14 months. Infant TC was associated with macronutrient intake and maternal TC.

This study assessed factors associated with the perceived dose of intervention received and with the participantsatisfaction in a school-based obesity prevention intervention. It also explored the variance in the dose of in-tervention received that was at the school level. Process evaluation data from a school-based intervention studyconducted in Oslo in 2007–2009 were used. A total of 542 11-year-olds from 12 intervention schools wereincluded. A web-based questionnaire was used to collect data. Descriptive analyses and multilevel regressionanalyses were conducted. Females and those with medium (vs. low) parental education had higher odds ofreporting a high vs. low dose of intervention received at mid-way (8 months after baseline). Perceived socialcapital and perceived social support for physical activity from friends at baseline were positively associated withthe dose of intervention received at mid-way. Perceived social capital at mid-way was positively associated withthe dose of intervention reported post-intervention (20 months after baseline). Around 20% of the variance inthe perceived dose of intervention received was at the school level. Satisfaction with the intervention was highoverall and higher for females for several intervention components at mid-way and at post-intervention. Thefactors identified in this study should be taken into consideration when planning future obesity preventioninterventions among youth.

Identifying the mechanisms behind socioeconomic inequalities in adiposity among youth is vital
for efforts aimed at combating these inequalities. The study explored whether a broad range of
behavioral and familial factors mediated the associations between parental education and indicators
of adiposity among adolescents. Baseline data from a school-based intervention study conducted
in 2007 among 11-year-old adolescents were used. Anthropometric outcomes, physical activity
and sedentary time among adolescents were objectively measured. Other behavioral variables and
parental waist circumference were self-reported. Mediation analyses were conducted. Among boys,
maternal waist circumference (WC), paternal WC and TV viewing mediated 16%, 11.5% and 13% of the
association between parental education and adolescent WC. The respective proportions when body
fat percentage was used as the outcome variable were 22.5%, 16% and 21%. Among girls, maternal
and paternal WC mediated 20% and 14% of the association between parental education and WC. The
respective proportions when body fat percentage was used as the outcome variable were 14% and
10%. Other included variables did not play any mediating role. Parental WC was found to be a mediator
of socioeconomic differences in adiposity in both genders; underlying mechanisms were however not
investigated. Among boys, reducing TV time could contribute to the reduction of social inequalities in
adiposity.

Dietary intake in adolescents does often not align with the recommended dietary guidelines. Excess intakes of added sugar and saturated fat, and insufficient vegetable intake are among the identified challenges, which can affect future health negatively. Identifying targets to improve dietary practices is therefore essential. The current study aimed to examine the prevalence of meal skipping and if meal skipping days had a different diet quality than other days, using data from a recent Norwegian dietary survey in adolescents (n = 689, age 12-14 years). Their dietary intake was recorded for four days, using a web-based record system. Differences between days with, and without, breakfast or lunch were explored using mixed effect models, adjusting for correlated data and covariates, including weekday-weekend effect. In total, 8% and 11% were days without breakfast and lunch, respectively. Days with breakfast or lunch were associated with higher intake of fibre, and higher odds of consuming fruits and berries, juice and smoothie, than days without breakfast or lunch. Weekdays with lunch were also associated with lower intakes of added sugar and total fat (in % of energy), and discretionary foods, compared to weekdays without lunch. Skipping breakfast and lunch was associated with reduced diet quality in adolescents. Targeting these meals, and in particular school lunch, is a potential way forward to improve adolescents' dietary intake.

Estimating dietary intake is important for both epidemiological and clinical studies. In large
studies, a balance has to be achieved between methods with high accuracy and methods
that are easy to use. The aim of the present study was to compare results from a pre-coded
scanable food diary (PFD) with results from a weighed record (WR) in a group of Norwegian
adults. We also explored differences in day-to-day energy intake and the distribution of
energy intake across the day in acceptable reporters (ARs) and underreporters (URs). Participants
(n = 114, mean age 35 years, 68% women) recorded dietary intake with the PFD
for 7 consecutive days. One week after completing the PFD, participants completed a 7
days WR. No difference in mean energy intake was seen between methods. Few differences
were seen for the macronutrients, the most noticeable difference being the percentage
of energy (E%) from carbohydrates which was significantly lower with the PFD (47 E%)
than with the WR (49 E%). For the micronutrients, intakes of calcium and vitamin A were
both significantly higher with the PFD than with the WR. Pearson's correlation coefficient
ranged from 0.47 (tocopherol) to 0.76 (E% carbohydrates) for all nutrients. Bread intake was
significantly lower with the PFD while the intakes of edible fats, cheese and beverages were
higher. Twenty-eight percent of the participants were found to be URs with the PFD. No
clear pattern of underreporting at certain recording days or times of the day was seen. In
conclusion, the results showed similar energy intakes and few differences in food and nutrient
intakes between the PDF and the WR at the group level. Somewhat larger differences
between the methods were seen at the individual level. Because of the reduced work load
on both participants and researchers, the PFD seems a suitable alternative to the WR.

Hyaluronic acid (HA) is a high-molecular-mass polysaccharide, that is endogenously produced and present in connective tissue, synovial fluid, intraoccular fluid, and skin. The basic unit of the HA polymer consists of D-glucuronic acid and N-acetyl-D-glucosamine.
The Norwegian Food Safety Authority has requested VKM to evaluate the risk of adverse effects related to daily intake of food supplements with 150 mg, 120 mg, 64 mg, and 48 mg HA. Exposure from other sources of HA (food, cosmetics, and different medical applications) is not estimated.
