"I'm not sure whether I will implement it": exploring barriers and facilitators to implementing a digital "healthy eating" resource in early education and care settings - teachers' perspectives.

BACKGROUND: Scaling up effective interventions to promote healthy eating habits in children in real-world settings is a pressing need. The success of implementation hinges crucially on engaging end-users and tailoring interventions to meet their specific needs. Building on our prior evaluation of a digital "healthy eating" resource for early childhood education and care (ECEC) staff; this qualitative study aims to pinpoint the barriers and facilitators that influence the successful implementation of such interventions. METHODS: We conducted twelve semi-structured interviews with ECEC teachers in a Norwegian municipality. Interview participants were later invited to participate in focus groups where two discussions were conducted with five of the participants to reflect on the initial interview findings. Thematic analysis, facilitated by NVivo software, was employed to analyse the data, aiming to identify and summarize teachers' subjective experiences and perspectives. RESULTS: Teachers' perceptions of barriers to the implementation of an upcoming digital "healthy eating" resource included: (1) No established tradition of using digital resources at work; (2) Uncertainty regarding the achievable outcomes of implementation; (3) Perception of the new "healthy eating" resource as cooking-focused and unnecessary; and (4) Hectic everyday life serving as a barrier to the long-term use of a digital resource. Facilitators for implementation included: (1) A user-friendly format; (2) Newsletters featuring seasonal tips inspire and serve as effective reminders; (3) Emphasis on research and legislation; and (4) Structuring the resource as a series and an idea bank. CONCLUSIONS: The findings underscore the essential need for tailored strategies and comprehensive support structures to successfully implement a culturally appropriate digital "healthy eating" resource for ECEC staff, ensuring effectiveness and feasibility. TRIAL REGISTRATION: This study was not registered in a trial registry as it is not a clinical trial or intervention study but serves as a pilot for the Nutrition Now study, trial identifier ISRCTN10694967 ( https://doi.org/10.1186/ISRCTN10694967 ), registration date: 19/06/2022.

Nutrition in a lifecourse perspective: From molecular aspects to public health approaches.

This Special Issue covers a variety of topics related to nutrition from a lifecourse perspective, addressing diet in sensitive periods (preconception, pregnancy and infancy/toddlerhood), in different contexts, spanning from molecular nutrition to settings and gatekeepers of diet in these sensitive periods. It highlights challenges and research gaps within the field.

Staff feeding practices, food neophobia, and educational level in early education and care settings: A cross-sectional study.

Feeding practices in early childhood education and care (ECEC) settings are important for the development of healthy eating habits early in life. However, there is limited research on feeding practices among ECEC staff working with infants and toddlers, and how these practices relate to staff education. This study assessed the feeding practices, level of food neophobia, and participation in shared meals among ECEC staff, and examined whether there were differences in feeding practices related to education and shared meals. Furthermore, we explored the association between food neophobia levels among ECEC staff and their respective feeding practices in ECEC. In total, 130 ECEC teachers and other staff from two Norwegian ECEC trials completed a questionnaire about feeding practices and level of food neophobia. Our results showed that ECEC staff commonly used modelling and encouraging balance and variety feeding practices, but used food as a reward and emotion regulation less often. These practices differed by staff educational level, favoring highly educated staff. We found that more than half of ECEC staff ate lunch together with the children every day, and those who did so used positive feeding practices (encouraging balance and variety and modelling) more than those who did not eat with children; however, they also used restriction for health more often. Higher scores on food neophobia were associated with less use of emotion regulation and restriction for health when adjusted for relevant variables. In conclusion, our results show there is potential to improve feeding practices in ECEC, especially focusing on ECEC staff with low education. Suggested ways forward are updating guidelines to cover feeding practices and working on implementing these guidelines.

Associations between sleep deficit and academic achievement - triangulation across time and subject domains among students and teachers in TIMSS in Norway.

BACKGROUND: Sufficient sleep is important to an individual's health and well-being, but also for school achievement among adolescents. This study investigates the associations between sleepiness, sleep deficits, and school achievements among adolescents. METHODS: This trend study involved a representative sample of Norwegian adolescents based on the "Trends in International Mathematics and Science Study" (TIMSS), N = 4499 (2015) and N = 4685 (2019) and their teachers. The students were 9th graders from a Norwegian compulsory secondary school. The survey included questions on students' sleepiness as students reported in 2019 and sleep deficits among students that limited teaching in class as their teachers reported in 2015 and 2019. Regression, triangulation, and mediation analyses were used. Mplus was used to perform the statistical analyses. RESULTS: The results revealed significant negative associations between sleep deficits and school achievements, adjusted for gender, socioeconomic status (SES), and minority status among Norwegian 9th graders. These results were found for both mathematics and science achievements in 2015 and 2019. Sleepiness that the students reported was negatively associated with school achievements in 2019. Trend and mediation analyses showed that sleep deficits explained 18 and 11% of the decrease in mathematics and science achievements, respectively, from 2015 to 2019. CONCLUSIONS: Sleep deficits were associated with school achievements in mathematics and science among Norwegian 9th graders. Mediation analyses revealed that sleep deficits explained a significant part of the decline in academic achievements. Insufficient sleep may have negative public health implications and influence adolescents' academic achievements and competences, and should therefore be discussed in both the educational and health systems.

Alcohol consumption among students and its relationship with nutritional intake: a cross-sectional study.

OBJECTIVE: Excessive alcohol consumption during reproductive years may impact the integrity of developing eggs and sperm, potentially affecting the life-long health of future children. Inadequate diets could aggravate these preconception effects of alcohol. The aim of the present study was to assess the prevalence of excessive alcohol consumption and explore whether weekly alcohol intake is associated with energy and nutrient intake and adequacy of micronutrient intake among students. DESIGN: Cross-sectional survey using a validated and reproducibility-tested FFQ. SETTING: University of Agder, Norway, in 2018. PARTICIPANTS: 622 students (71 % female). RESULTS: More than 80 % reported having consumed alcoholic beverages the past 4 weeks. One-third of men and 13 % of women exceeded the upper recommended limit of 14 UK alcohol units/week. An inverse association between increasing alcohol intake and energy-adjusted micronutrient intake was evident for thiamine, phosphate, Fe, Zn and Se in men, and for vitamin A, ß-carotene, vitamin E and C, thiamine, vitamin B6, folate, P, Mg, K, Fe, Zn and Cu in women. A substantial proportion had vitamin D, folate, Fe and I intakes below average requirement regardless of alcohol consumption level. The combination of prevalent alcohol use, decreasing micronutrient density of diet across alcohol consumption level and a high probability of micronutrient inadequacy indicate reason for concern in a preconception public health perspective. CONCLUSIONS: Our findings call for investigations into young adults' knowledge, reflections and beliefs regarding diet and alcohol use to understand how these behaviours could be improved ahead of parenthood.

Parental phone use during mealtimes with toddlers and the associations with feeding practices and shared family meals: a cross-sectional study.

BACKGROUND: Positive parental feeding practices and a higher frequency of family meals are related to healthier child dietary habits. Parents play an essential role when it comes to the development of their child's eating habits. However, parents are increasingly distracted by their mobile phone during mealtimes. The aim of this study was to describe the feeding practices and daily shared family meals among parents who use and do not use a mobile phone during mealtimes, and further to explore the associations between the use of a mobile phone during mealtimes and feeding practices and daily shared family meals, respectively. METHODS: Cross-sectional data from the Food4toddler study were used to explore the association between mobile use during meals and parental feeding practices including family meals. In 2017/2018 parents of toddlers were recruited through social media to participate in the study. In total 298 out of 404 who volunteered to participate, filled in a baseline questionnaire, including questions from the comprehensive feeding practices questionnaire (CFPQ), questions of frequency of family meals and use of mobile phone during meals. RESULTS: Herein, 4 out of 10 parents reported various levels of phone use (meal distraction) during mealtimes. Parental phone use was associated with lower use of positive parental feeding practices like modelling (B = - 1.05 (95% CI -1.69; - 0.41)) and family food environment (B = - 0.77 (95% CI -1.51; - 0.03)), and more use of negative parental feeding practices like emotional regulation (B = 0.73 (95% CI 0.32; 1.14)) and the use of pressure to eat (B = 1.22 (95% CI 0.41; 2.03)). Furthermore, parental phone use was associated with a lower frequency of daily family breakfast (OR = 0.50 (95% CI 0.31; 0.82)) and dinner (OR = 0.57 (95% CI 0.35; 0.93)). CONCLUSIONS: Mobile phone use is common among parents during mealtimes, and findings indicate that parental phone use is associated with less healthy feeding practices and shared family meals. These findings highlight the importance of making parents aware of potential impacts of meal distractions. TRIAL REGISTRATION: ISRCTN92980420 . Registered 13 September 2017.

Family meal participation is associated with dietary intake among 12-month-olds in Southern Norway.

BACKGROUND: Family meal participation is associated with healthier eating among children and adolescents. Less is known about family meal participation among infants and toddlers. The objective of the present study was to explore whether family meal participation at 12 months of age is associated with dietary intake and whether a potential relationship differs according to maternal education or child sex. METHODS: Follow-up data from children born to mothers participating in the Norwegian Fit for Delivery (NFFD) trial during pregnancy were used to assess the frequency of intake of 11 dietary items according to frequency of participating in the respective family meals. Dietary differences according to seldom (0-3 times/week) or often (4-7 times/week) participating in each respective meal category were assessed in linear regression models. Potential dose-response associations with frequency of participation in all family meal categories combined were also estimated. Models were adjusted for maternal randomization status, education, and child sex. RESULTS: The sample comprised 408 children. A total of 74, 53 and 74% had breakfast, lunch, and dinner with family ≥4 times/week, respectively, while 39% had supper and 27% between-meal snacks with family ≥4 times/week. Having family dinner ≥4 times/week was associated with more frequent intake of vegetables, homemade infant cereal, milk, and water, and less frequent intake of commercial infant foods while the other family meal categories were associated with fewer dietary outcomes. For each additional meal category eaten with family ≥4 times/week, frequency of vegetable intake (ß = 0.45), water (ß = 0.17), and milk (ß = 0.09) per day increased, while commercial infant cereal was eaten less frequently (ß = - 0.18). The inverse association between family meals and commercial infant cereal was only evident in children born to mothers in the intervention group. Several associations with diet were stronger and only significant among boys. CONCLUSIONS: Being fed in the context of family meals at 12 months of age was associated with a more favorable diet. Including the infant in family meals has potential in the promotion of early nutritional health.

Wow! They really like celeriac! Kindergarten teachers' experiences of an intervention to increase 1-year-olds' acceptance of vegetables.

Exposure to varied foods in early life is important for short- and long-term health and development. Strategically introducing toddlers to new vegetables is not a common practice in Norwegian kindergartens. Therefore, we developed, conducted, and evaluated a web-based cluster randomised kindergarten intervention, Pre-schoolers' Food Courage 2.0. The purpose of the current qualitative study was to explore kindergarten teachers' experience of implementing this intervention and what they thought facilitated the positive impact of the intervention reported in the quantitative evaluation. Ten individual telephonic interviews with kindergarten teachers who took part in the intervention study were conducted using a semi-structured interview guide. Data were transcribed verbatim and subjected to thematic analysis. Five main themes were identified: 1) One-year-olds love food and renewal of the menus was inspiring; 2) One-year-olds are surprisingly willing to try and accept novel foods; 3) Novel food at meals stimulate social interaction; and 4) The Sapere method is a fun and explorative activity for 1-year-olds. These four themes were the features perceived as the effective elements of the intervention by the kindergarten teachers. The fifth main theme was: 5) Sustained impact on kindergarten teachers' practices and beliefs. The kindergarten teachers found the intervention easy to implement, and they were surprised by the foods 1-year-olds like and how the intervention increased their food acceptance. This age window of opportunity seems to be underused in kindergartens. By using the strategies described in the intervention, kindergarten staff effectively took advantage of this opportunity and consequently, child and kindergarten staff behaviour in relation to food was enhanced. Interventions targeting healthy feeding practices may potentially have a long-term public health impact by increasing food variety and vegetable intake in toddlers.

Effect of a Parent-Focused eHealth Intervention on Children's Fruit, Vegetable, and Discretionary Food Intake (Food4toddlers): Randomized Controlled Trial.

BACKGROUND: In Western countries, children's diets are often low in fruits and vegetables and high in discretionary foods. Diet in early life tends to track through childhood and youth and even into adulthood. Interventions should, therefore, be delivered in periods when habitual traits are established, as in toddlerhood when children adapt to their family's diet. OBJECTIVE: In this study, we assessed the effect of the Food4toddlers eHealth intervention, which aimed to enhance toddlers' diets by shaping their food and eating environment. METHODS: The Food4toddlers randomized controlled trial was conducted in Norway in 2017-2018. Parent-child dyads were recruited through social media. In total, 298 parents completed an online questionnaire at baseline (mean child age 10.9 months, SD 1.2). Postintervention questionnaires were completed immediately after the intervention (ie, follow-up 1; mean child age 17.8 months, SD 1.3) and 6 months after the intervention (ie, follow-up 2; mean child age 24.2 months, SD 1.9). The intervention was guided by social cognitive theory, which targets the linked relationship between the person, the behavior, and the environment. The intervention group (148/298, 49.7%) got access to the Food4toddlers website for 6 months from baseline. The website included information on diet and on how to create a healthy food and eating environment as well as activities, recipes, and collaboration opportunities. To assess intervention effects on child diet from baseline to follow-up 1 and from baseline to follow-up 2, we used generalized estimating equations and a time × group interaction term. Between-group differences in changes over time for frequency and variety of fruits and vegetables and frequency of discretionary foods were assessed. RESULTS: At follow-up 1, a significant time × group interaction was observed for the frequency of vegetable intake (P=.02). The difference between groups in the change from baseline to follow-up 1 was 0.46 vegetable items per day (95% CI 0.06-0.86) in favor of the intervention group. No other significant between-group differences in dietary changes from baseline to follow-up 1 or follow-up 2 were observed. However, there is a clear time trend showing that the intake of discretionary foods increases by time from less than 1 item per week at baseline to more than 4 items per week at 2 years of age (P<.001), regardless of group. CONCLUSIONS: A positive intervention effect was observed for the frequency of vegetable intake at follow-up 1 but not at follow-up 2. No other between-group effects on diet were observed. eHealth interventions of longer duration, including reminders after the main content of the intervention has been delivered, may be needed to obtain long-terms effects, along with tailoring in a digital or a personal form.

Effect of a free healthy school meal on fruit, vegetables and unhealthy snacks intake in Norwegian 10- to 12-year-old children.

BACKGROUND: Norwegian children have a lower intake of fruit, vegetables, and a higher intake of unhealthy snacks compared to dietary guidelines. Such dietary inadequacies may be detrimental for their current and future health. Schools are favorable settings to establish healthy eating practices. Still, no school meal arrangement is provided in Norway, and most children typically bring packed lunches from home. The aim of this study was to investigate whether serving a free healthy school meal for one year resulted in a higher intake of fruit and vegetables and a lower intake of unhealthy snacks in total among 10-12-year-olds in Norway. METHODS: The School Meal Project in Southern Norway was a non-randomized trial in two elementary schools in rural areas in the school year 2014/2015. The study sample consisted of 10- to 12-year-old children; an intervention group (N = 55) and a control group (N = 109) resulting in a total of 164 school children at baseline. A food frequency questionnaire was completed by the children at baseline, at five months follow-up and after one year to assess fruit, vegetable, and snacks intake. Multiple linear regression analyses were performed to assess intervention effects on overall intake of fruit and vegetables and unhealthy snacks. RESULTS: Serving of a free healthy school meal for one year was associated with a higher weekly intake of vegetables on sandwiches in the intervention group compared to the control group, adjusted for baseline intake (B: 1.11 (95% CI: .38, 1.85)) at the end of the intervention. No other significant intervention effects were found for the remaining fruit and vegetables measures. Serving of a free healthy school meal was not associated with a lower weekly intake of unhealthy snacks (i.e. potato chips, candy, sugar sweetened beverages) in the intervention group compared to the control group. CONCLUSIONS: A free healthy school meal was associated with a higher weekly intake of vegetables on sandwiches but did not significantly change any other investigated dietary behaviors. However, given the inadequate intake of vegetables among children and that even moderate improvements have public health relevance, a free healthy school meal for all school children could be beneficial.

Evaluation of an eHealth intervention aiming to promote healthy food habits from infancy -the Norwegian randomized controlled trial Early Food for Future Health.

BACKGROUND: Strategies to optimize early-life nutrition provide an important opportunity for primary prevention of childhood obesity. Interventions that can be efficiently scaled-up to the magnitude needed for sustainable childhood obesity prevention are needed. The objective of this study was to evaluate the effects of an eHealth intervention on parental feeding practices and infant eating behaviors. METHODS: The Norwegian study Early Food for Future Health is a randomized controlled trial. Parents were recruited via social media and child health clinics during spring 2016 when their child was aged 3 to 5 months. In total 718 parents completed a web-based baseline questionnaire at child age 5.5 months. The intervention group had access to a webpage with monthly short video clips addressing specific infant feeding topics and age-appropriate baby food recipes from child age 6 to 12 months. The control group received routine care. The primary outcomes were child eating behaviors, dietary intake, mealtime routines and maternal feeding practices and feeding styles. The secondary outcomes were child anthropometry. This paper reports outcomes at child age 12 months. RESULTS: More than 80% of the intervention group reported viewing all/most of the video clips addressing infant feeding topics and indicated that the films were well adapted to the child's age and easy to understand. Children in the intervention group were served vegetables/fruits more frequently (p = 0.035) and had tasted a wider variety of vegetables (p = 0.015) compared to controls. They were also more likely to eat family breakfast (p = 0.035) and dinner (p = 0.011) and less likely to be playing or watching TV/tablet during meals (p = 0.009) compared to control-group children. We found no group differences for child anthropometry or maternal feeding practices. CONCLUSIONS: Our findings suggest that the eHealth intervention is an appropriate and feasible tool to propagate information on healthy infant feeding to Norwegian mothers. Our study also suggests that anticipatory guidance on early protective feeding practices by such a tool may increase young children's daily vegetable/fruit intake and promote beneficial mealtime routines.

Free school meals as an approach to reduce health inequalities among 10-12- year-old Norwegian children.

BACKGROUND: Children spend a considerable amount of time at school and consume at least one meal/day. This study aimed to investigate if a free, healthy school meal every day for one school year was associated with children's intake of healthy foods at school, weight status and moderating effects of socio-economic status. METHODS: A non-randomized study design with an intervention and a control group was used to measure change in children's dietary habits at lunchtime. In total, 164 children participated; 55 in the intervention group and 109 in the control group (baseline). Intervention-children were served a free, healthy school meal every school day for one year. Participating children completed a food frequency questionnaire at baseline, at five months follow-up and after one year. Children's anthropometrics were measured at all three timepoints. Intervention effects on children's Healthy food score, BMI z-scores, and waist circumference were examined by conducting a Repeated Measures Multivariate ANOVA. Moderating effects of children's gender and parental socio-economic status were investigated for each outcome. RESULTS: A significant intervention effect on children's outcomes (multivariate) between baseline and after one year (F = 2.409, p < 0.001), and between follow-up 1 at five months and after one year (F = 8.209, p < 0.001) compared to the control group was found. The Univariate analyses showed a greater increase in the Healthy food score of the intervention group between baseline and follow-up 1 (F = 4.184, p = 0.043) and follow-up 2 (F = 10.941, p = 0.001) compared to the control group. The intervention-children had a significant increase in BMI z-scores between baseline and follow-up 2 (F = 10.007, p = 0,002) and between follow-up 1 and 2 (F = 22.245, p < 0.001) compared to a decrease in the control-children. The intervention-children with lower socio-economic status had a significantly higher increase in Healthy food score between baseline and follow-up 2 than the control-children with lower socio-economic status (difference of 2.8 versus 0.94), but not among children with higher socio-economic status. CONCLUSIONS: Serving a free school meal for one year increased children's intake of healthy foods, especially among children with lower socio-economic status. This study may contribute to promoting healthy eating and suggests a way forward to reduce health inequalities among school children. TRIAL REGISTRATION: ISRCTN61703361 .

Adherence to the New Nordic Diet during pregnancy and subsequent maternal weight development: a study conducted in the Norwegian Mother and Child Cohort Study (MoBa).

The rising prevalence of overweight and obesity is a worldwide public health challenge. Pregnancy and beyond is a potentially important window for future weight gain in women. We investigated associations between maternal adherence to the New Nordic diet (NND) during pregnancy and maternal BMI trajectories from delivery to 8 years post delivery. Data are from the Norwegian Mother and Child Cohort. Pregnant women from all of Norway were recruited between 1999 and 2008, and 55 056 are included in the present analysis. A previously constructed diet score, NND, was used to assess adherence to the diet. The score favours intake of Nordic fruits, root vegetables, cabbages, potatoes, oatmeal porridge, whole grains, wild fish, game, berries, milk and water. Linear spline multi-level models were used to estimate the association. We found that women with higher adherence to the NND pattern during pregnancy had on average lower post-partum BMI trajectories and slightly less weight gain up to 8 years post delivery compared with the lower NND adherers. These associations remained after adjustment for physical activity, education, maternal age, smoking and parity (mean diff at delivery (high v. low adherers): -0·3 kg/m2; 95 % CI -0·4, -0·2; mean diff at 8 years: -0·5 kg/m2; 95 % CI -0·6, -0·4), and were not explained by differences in energy intake or by exclusive breast-feeding duration. Similar patterns of associations were seen with trajectories of overweight/obesity as the outcome. In conclusion, our findings suggest that the NND may have beneficial properties to long-term weight regulation among women post-partum.

Socio-economic status and maternal BMI are associated with duration of breast-feeding of Norwegian infants.

OBJECTIVE: To explore whether there is an association between socio-economic status and maternal BMI and duration of any breast-feeding/exclusive breast-feeding among Norwegian infants at 4 and 5 months of age in 2016. DESIGN: Cross-sectional design. Baseline data from a randomized controlled trial. Data concerning breast-feeding were collected by FFQ. SETTING: Recruitment was done at child health-care centres and through Facebook in 2016. In total, 960 infants/parents registered for participating in the study Early Food for Future Health. SUBJECTS: A total of 715 infant/mother dyads completed the questionnaire when the child was between 5 and 6 months old. RESULTS: At 5 months of age, 81·0 % of infants were breast-fed and 16·4 % were exclusively breast-fed. Infants of highly educated mothers had higher odds of being breast-fed at 5 months compared with infants of mothers with less education. Infants of multiparous mothers had higher odds of being exclusively breast-fed for the first 5 months compared with infants of mothers with one child. Infants of mothers with overweight/obesity had reduced odds of both being breast-fed at all and being exclusively breast-fed at 4 months of age compared with infants of mothers with normal BMI. CONCLUSIONS: Our results show that duration of breast-feeding varies with socio-economic status and maternal BMI in Norway. Targeting groups with low socio-economic status and mothers with overweight or obesity is important, as they are less likely to breast-feed according to recommendations.

Changes in fruit and vegetable consumption habits from pre-pregnancy to early pregnancy among Norwegian women.

BACKGROUND: A healthy diet is important for pregnancy outcome and the current and future health of woman and child. The aims of the study were to explore the changes from pre-pregnancy to early pregnancy in consumption of fruits and vegetables (FV), and to describe associations with maternal educational level, body mass index (BMI) and age. METHODS: Healthy nulliparous women were included in the Norwegian Fit for Delivery (NFFD) trial from September 2009 to February 2013, recruited from eight antenatal clinics in southern Norway. At inclusion, in median gestational week 15 (range 9-20), 575 participants answered a food frequency questionnaire (FFQ) where they reported consumption of FV, both current intake and recollection of pre-pregnancy intake. Data were analysed using a linear mixed model. RESULTS: The percentage of women consuming FV daily or more frequently in the following categories increased from pre-pregnancy to early pregnancy: vegetables on sandwiches (13 vs. 17%, p <0.01), other vegetables (11 vs. 14%, p = 0.01), fruits (apples, pears, oranges or bananas) (24 vs. 41%, p < 0.01), other fruits and berries (8 vs. 15%, p < 0.01) and fruits and vegetables as snacks (14 vs. 28%, p < 0.01). The percentage of women who reported at least daily consumption of vegetables with dinner (22% at both time points) was stable. A higher proportion of older women increased their consumption of vegetables and fruits as snacks from pre-pregnancy to early pregnancy compared to younger women (p=0.04). CONCLUSIONS: We found an increase in the proportion of women consuming FV daily or more frequently from pre-pregnancy to early pregnancy.

The effect of a prenatal lifestyle intervention on glucose metabolism: results of the Norwegian Fit for Delivery randomized controlled trial.

BACKGROUND: The effectiveness of prenatal lifestyle intervention to prevent gestational diabetes and improve maternal glucose metabolism remains to be established. The Norwegian Fit for Delivery (NFFD) randomized, controlled trial studied the effect of a combined lifestyle intervention provided to a general population, and found significantly lower gestational weight gain among intervention participants but no improvement in obstetrical outcomes or the proportion of large infants. The aim of the present study is to examine the effect of the NFFD intervention on glucose metabolism, including an assessment of the subgroups of normal-weight and overweight/obese participants. METHODS: Healthy, non-diabetic women expecting their first child, with pre-pregnancy body mass index (BMI) ≥19 kg/m2, age ≥ 18 years and a singleton pregnancy of ≤20 gestational-weeks were enrolled from healthcare clinics in southern Norway. Gestational weight gain was the primary endpoint. Participants (n = 606) were individually randomized to intervention (two dietary consultations and access to twice-weekly exercise groups) or control group (routine prenatal care). The effect of intervention on glucose metabolism was a secondary endpoint, measuring glucose (fasting and 2-h following 75-g glucose load), insulin, homeostatic assessment of insulin resistance (HOMA-IR) and leptin levels at gestational-week 30. RESULTS: Blood samples from 557 (91.9%) women were analyzed. For the total group, intervention resulted in reduced insulin (adj. Mean diff -0.91 mU/l, p = 0.045) and leptin levels (adj. Mean diff -207 pmol/l, p = 0.021) compared to routine care, while glucose levels were unchanged. However, the effect of intervention on both fasting and 2-h glucose was modified by pre-pregnancy BMI (interaction p = 0.030 and p = 0.039, respectively). For overweight/obese women (n = 158), intervention was associated with increased risk of at least one glucose measurement exceeding International Association of Pregnancy and Diabetes Study Group thresholds (33.7% vs. 13.9%, adj. OR 3.89, p = 0.004). CONCLUSIONS: The Norwegian Fit for Delivery intervention lowered neither glucose levels nor GDM incidence, despite reductions in insulin and leptin. Prenatal combined lifestyle interventions designed for a general population may be unsuited to reduce GDM risk, particularly among overweight/obese women, who may require earlier and more targeted interventions.

Intervention study on school meal habits in Norwegian 10-12-year-old children.

AIM: The aim of this study was to investigate whether a free school meal every day was associated with children's intake of healthy food during school. METHODS: A non-randomized study design with an intervention and a control group was used to measure change in children's meal habits at lunchtime. In total, 164 children participated; 55 in the intervention group and 109 in the control group. Children in the intervention group were served a free, healthy school meal every school day. Participating children completed a questionnaire at baseline and at 6 months' follow up. Possible associations were evaluated with a healthy food score, which was calculated based on a food frequency questionnaire on lunch habits at school. Chi-square and Independent Samples t-test were used to analyse the data. RESULTS: At baseline, there was no significant difference in the healthy food score between the intervention and the control group ( p = 0.08). Children in the intervention group increased their healthy food score significantly compared with children in the control group after 6 months ( p ⩽ 0.01). Change in the healthy food score was mainly due to an increase in the intake of fruit ( p ⩽ 0.01), vegetables ( p ⩽ 0.01) and fish spread ( p = 0.02); all in favour of the intervention group. CONCLUSIONS: A serving of a free school meal every day for 6 months increased children's intake of healthy food at lunchtime compared with the control group. Further studies are needed to establish possible long-term effects.

Change in active transportation and weight gain in pregnancy.

BACKGROUND: Pregnancy is characterised by large weight gain over a short period, and often a notable change in mode of transportation. This makes pregnancy suitable for examining the plausible, but in the scientific literature still unclear, association between active transportation and weight gain. We hypothesize that women continuing an active mode of transportation to work or school from pre- to early pregnancy will have a lower gestational weight gain (GWG) than those who change to a less active mode of transportation. METHODS: We analysed prospective data from the Norwegian Fit for Delivery (NFFD) trial. Between September 2009 and February 2013 606 women were consecutively enrolled in median gestational week 16 (range; 8-20). Of 219 women who used an active mode of transportation (biking, walking, public transportation) pre-pregnancy, 66 (30%) converted to a less active mode in early pregnancy ("active-less active" group), and 153 (70%) continued with active transportation ("active-active" group). Pre-pregnancy weight was self-reported. Weight at gestational (GA) weeks 16, 30, 36, and at term delivery was objectively measured. Weight gain was compared between the two groups. Linear mixed effects analysis of the repeated weight measures was performed including the group*time interaction. RESULTS: A significant overall group effect was observed for the four time points together ("active-active" group: 77.3 kg vs. "active-less active" group: 78.8 kg, p = 0.008). The interaction term group*time was significant indicating different weight gain throughout pregnancy for the two groups; the mean differences between the groups were 0.7 kg at week 16, 1.4 kg at week 30, 2.1 kg at week 36, and 2.2 kg at term delivery, respectively. CONCLUSION: The findings indicate that active transportation is one possible approach to prevent excessive weight gain in pregnancy.

Changes in beverage consumption from pre-pregnancy to early pregnancy in the Norwegian Fit for Delivery study.

OBJECTIVE: To describe changes in consumption of different types of beverages from pre-pregnancy to early pregnancy, and to examine associations with maternal age, educational level and BMI. DESIGN: Cross-sectional design. Participants answered an FFQ at inclusion into a randomized controlled trial, the Fit for Delivery (FFD) trial, in median gestational week 15 (range: 9-20), reporting current consumption and in retrospect how often they drank the different beverages pre-pregnancy. SETTING: Eight local antenatal clinics in southern Norway from September 2009 to February 2013. SUBJECTS: Five hundred and seventy-five healthy pregnant nulliparous women. RESULTS: Pre-pregnancy, 27 % reported drinking alcohol at least once weekly, compared with none in early pregnancy (P<0.001). The percentage of women drinking coffee (38 % v. 10 %, P<0.001), sugar-sweetened beverages (10 % v. 6 %, P=0.011) and artificially sweetened beverages (12 % v. 9 %, P=0.001) at least daily decreased significantly from pre-pregnancy to early pregnancy, while the percentage of women who reported to drink water (85 % v. 92 %, P<0.001), fruit juice (14 % v. 20 %, P=0.001) and milk (37 % v. 42 %, P=0.001) at least daily increased significantly. From pre-pregnancy to early pregnancy higher educated women reduced their consumption frequency of coffee significantly more than women with lower education. Older women reduced their consumption frequency of coffee and artificially sweetened beverages and increased their consumption frequency of fruit juice and milk significantly more than younger women. CONCLUSIONS: There is a significant change in beverage consumption from pre-pregnancy to early pregnancy among Norwegian nulliparous women.

The Fit for Delivery study: rationale for the recommendations and test-retest reliability of a dietary score measuring adherence to 10 specific recommendations for prevention of excessive weight gain during pregnancy.

Aiming at preventing excessive weight gain during pregnancy, 10 specific dietary recommendations are given to pregnant women in the intervention arm of the Norwegian Fit for Delivery (FFD) study. This paper presents the rationale and test-retest reliability of the food frequency questionnaire (FFQ) and a dietary score measuring adherence to the recommendations. The study is part of the ongoing FFD study, a randomised, controlled, intervention study in nulliparous pregnant women. A 43-item FFQ was developed for the FFD study. A dietary score was constructed from 10 subscales corresponding to the 10 dietary recommendations. Adding the subscales yielded a score from 0 to 10 with increasing score indicating healthier dietary behaviour. The score was divided into tertiles, grouping participants into low, medium and high adherence to the dietary recommendations. Pregnant women attending ultrasound screening at about week 19 of pregnancy were asked to complete the FFQ twice, 2 weeks apart. Of 154 pregnant women completing the first questionnaire, 106 (69%) completed the form on both occasions and was included in the study. The test-retest correlations of the score and subscales were r = 0.68 and r = 0.56-0.84, respectively (both P ≤ 0.001). There was 68% test-retest correct classification of the score and 70-87% of the subscales. In conclusion, acceptable test-retest reliability of the FFQ and the dietary score was found. The score will be used in the FFD study to measure adherence to the dietary recommendations throughout pregnancy and in the following year post-partum.
