RESUMO

We examined the association between parental educational level (PEL) and children's food consumption and nutrient intake in a sample of Finnish 3- to 6-year-old preschoolers (n 811). The data were obtained from the cross-sectional DAGIS project, conducted in eight municipalities in Finland during 2015-2016. The food consumption and nutrient intake were assessed using food records. The highest educational level of the family was used as the indicator of socio-economic status. Differences in diet by PEL were analysed using a hierarchical linear model adjusted for energy intake. Compared with high PEL, low PEL was associated with a child's lower consumption of fresh vegetables and salads, vegetarian dishes, berries, white bread, blended spread, skimmed milk and ice cream but higher consumption of milk with 1-1·5 % fat content, dairy-based desserts and sugar-sweetened soft drinks. Food consumption was also examined after disaggregating dishes into their ingredients. Low PEL was associated with lower consumption of vegetables, nuts and seeds, berries and fish but higher consumption of red meat. Children in the low PEL, compared with the high PEL group, had a lower intake of protein, fibre, EPA, DHA, vitamin D, riboflavin, vitamin B6, folate, vitamin B12, vitamin C, potassium, phosphorous, Ca, Mg, Zn and iodine but a higher intake of fat and saturated, trans and MUFA. The observed diet-related disparities highlight the need for policy actions and interventions supporting healthy eating patterns such as high consumption of vegetables, nuts and berries in childhood, paying special attention to those with low PEL.

RESUMO

OBJECTIVE: This study aimed to (1) examine the clustering of energy balance-related behaviours (EBRB) and (2) investigate whether EBRB clusters, temperament and hair cortisol concentration (HCC) associate with overweight. DESIGN: We assessed food consumption using food records, screen time (ST) using sedentary behaviour diaries, sleep consistency and temperament (negative affectivity, surgency, effortful control) using questionnaires and HCC using hair samples. Accelerometers were used to assess physical activity (PA) intensities, sleep duration and sleep efficiency. Researchers measured each child's weight and height. We used finite mixture models to identify EBRB clusters and multilevel logistic regression models to examine the associations between EBRB clusters, temperament, HCC and overweight. SETTING: The cross-sectional DAGIS survey, data collected in 2015-2016. PARTICIPANTS: Finnish 3-6-year-olds (n 864) recruited through preschools. RESULTS: One-third of the participants were categorised into the cluster labelled 'Unhealthy diet, excessive screen time', characterised by unhealthy dietary choices (e.g. greater consumption of high-fat, high-sugar dairy products) and longer ST. Two-thirds were categorised into the second cluster, labelled 'Healthy diet, moderate screen time'. PA and sleep were irrelevant for clustering. Higher negative affectivity and lower effortful control associated with the 'Unhealthy diet, excessive screen time' cluster. EBRB clusters and HCC did not associate with overweight, but surgency was positively associated with overweight (OR = 1·63, 95 % CI 1·17, 2·25). CONCLUSIONS: Of the EBRB, food consumption and ST seem to associate. As temperament associates with EBRB clusters and overweight, tailored support acknowledging the child's temperament could be profitable in maintaining a healthy weight.

RESUMO

PURPOSE: The EAT-Lancet reference diet is a healthy plant-based diet produced within planetary boundaries. To inform the food system transformation, we compared Finnish pre-schoolers' food consumption with the reference diet's food group targets. METHODS: Food record data for 3- to 6-year-old pre-schoolers were collected in the cross-sectional DAGIS survey. Ingredients of composite dishes were available in the data. In addition, we manually decomposed industrial products such as sausages and biscuits by estimating the shares of ingredients. We also estimated the consumption of added sugars and converted the consumption of dairy products into milk equivalents. We used usual intake modelling to estimate the mean consumption and the proportion of children who met the reference diet's targets. We set the target amounts separately for 3- to 4-year-olds and 5- to 6-year-olds in grams by proportioning the published target amounts (assuming a 2500 kcal diet) to the children's mean reported energy intake. RESULTS: For both age groups (3- to 4-year-olds, n = 460; 5- to 6-year-olds, n = 402), the daily mean consumption of whole grains, vegetables, legumes, nuts, and unsaturated oils was below targets, whereas the consumption of red meat, dairy foods, tubers, and added sugars was above targets. The consumption of fruit and fish was in line with targets. CONCLUSION: To comply with the reference diet's targets, major changes in the diets of Finnish children are needed. The key food groups targeted for higher consumption are whole grains and legumes and targeted for lower consumption red meat and dairy products.

RESUMO

PURPOSE: An optimal diet for lowering the risk of gestational diabetes mellitus (GDM) is still to be defined, but may comprise of nutrient intakes, dietary patterns, diet quality, and eating frequency. This study was designed to investigate the contribution of diet in developing GDM in a comprehensive way. METHODS: The dietary intake of overweight or obese women, a risk group for GDM (n = 351), was assessed using 3-day food diaries and diet quality questionnaires in early pregnancy. Eating frequency and nutrient intakes were calculated, and dietary patterns identified using principal component analysis. The inflammatory potential of the diet was determined by calculating the dietary inflammatory index (DII®) and energy-adjusted DII (E-DII™). GDM was diagnosed with an oral glucose tolerance test at 24-28 gestational weeks. RESULTS: Higher adherence to 'healthier dietary pattern' characterized by consumptions of vegetables and rye bread associated with a reduced risk of GDM (adjusted OR 0.27, 95% CI 0.11-0.70). Higher E-DII score, indicating pro-inflammatory diet, was associated with a 27% higher risk of GDM (adjusted OR 1.27; 95% CI 1.08-1.49) for each E-DII point. In the evaluation of nutrient intakes, total fat, saturated fatty acids (SFAs), and trans fatty acids were higher and fiber lower in women developing GDM compared to women not developing GDM (all p < 0.05). Intakes of total fat, SFAs, and trans fatty acids were also significant predictors for GDM (all p < 0.05). CONCLUSIONS: The results emphasize the importance of an overall healthy diet and limitation of foods with SFAs, and other nutrients with a high inflammatory potential in reducing the risk of GDM.

RESUMO

PURPOSE: A shift towards more plant-based diets promotes both health and sustainability. However, controlled trials addressing the nutritional effects of replacing animal proteins with plant proteins are lacking. We examined the effects of partly replacing animal proteins with plant proteins on critical vitamin and mineral intake and statuses in healthy adults using a whole-diet approach. METHODS: Volunteers aged 20-69 years (107 female, 29 male) were randomly allocated into one of three 12-week intervention groups with different dietary protein compositions: ANIMAL: 70% animal-source protein/30% plant-source protein; 50/50: 50% animal/50% plant; PLANT: 30% animal/70% plant; all with designed protein intake of 17 E%. We analysed vitamin B-12, iodine, iron, folate, and zinc intakes from 4-day food records, haemoglobin, ferritin, transferrin receptor, folate, and holotranscobalamin II from fasting blood samples, and iodine from 24-h urine. RESULTS: At the end point, vitamin B-12 intake and status were lower in PLANT than in 50/50 or ANIMAL groups (P ≤ 0.007 for all). Vitamin B-12 intake was also lower in 50/50 than in ANIMAL (P < 0.001). Iodine intake and status were lower in both 50/50 and PLANT than in ANIMAL (P ≤ 0.002 for all). Iron and folate intakes were higher in PLANT than in ANIMAL (P < 0.001, P = 0.047), but no significant differences emerged in the respective biomarkers. CONCLUSIONS: Partial replacement of animal protein foods with plant protein foods led to marked decreases in the intake and status of vitamin B-12 and iodine. No changes in iron status were seen. More attention needs to be paid to adequate micronutrient intakes when following flexitarian diets. CLINICAL TRIAL REGISTRY: NCT03206827; registration date: 2017-06-30.

RESUMO

OBJECTIVE: We aimed to examine associations between early educators' feeding practices and opinions and children's dietary intake at pre-school, in a context where uniform meals are served and pre-schools are highly regulated. DESIGN: Cross-sectional study. Food consumption data of the children consisted of two-day food records from pre-school kept by early educators. Early educators also reported their feeding practices and opinions on pre-school food. Serving style was observed. SETTING: Municipal pre-schools in Southern and Western Finland.ParticipantsPre-schoolers (n 586) aged 3-6 years and early educators (n 378). RESULTS: Early educators' positive opinion of the food served at pre-school and the opinion that sufficient vegetables were available for the children were positively associated with children's vegetable consumption. Early educators' role modelling and a positive opinion of the food were negatively associated with children's energy intake. Encouragement to eat fruit and vegetables was associated with higher fibre intake. Intake of added sugar was low (4·4 % of energy). CONCLUSIONS: Some of the feeding practices and opinions of early educators were related to healthier dietary intake (higher vegetable consumption and fibre intake) among the children. However, in some respects, the results contradicted previous findings. Overall, early educators' feeding practices and opinions contribute to children's dietary intake and should be taken into account when promoting healthy food intake among pre-school children.

RESUMO

Although evidence exists of the association between children's temperament and weight, only few studies have examined how temperament is associated with actual food consumption among preschoolers. We examined concurrent associations between children's temperament and the consumption of different foods, and investigated whether the association between children's temperament and vegetable consumption is mediated by vegetable-related parenting practices. We utilized the data from the cross-sectional DAGIS study of 864 preschool children aged between three to six and their families, conducted between 2015 and 2016 in Finland. The parents reported their children's temperament, food consumption, and their vegetable-related parenting practices. Adjusted logistic regression analyses found positive associations between surgency and vegetable consumption as well as between effortful control and vegetable consumption. Both associations were mediated by one examined vegetable-related parenting practice: enhanced availability and autonomy support. No associations were found between children's negative affectivity and food consumption or vegetable-related parenting practices. In conclusion, children's temperament may be an important factor behind food-related parenting practices and children's diet. However, further longitudinal research and research covering different food-related parenting practices and home environment factors is necessary to better understand the complex associations between temperament and food consumption among young children.

RESUMO

OBJECTIVE: To carry out an inventory on the availability, challenges, and needs of dietary assessment (DA) methods in Africa as a pre-requisite to provide evidence, and set directions (strategies) for implementing common dietary methods and support web-research infrastructure across countries. METHODS: The inventory was performed within the framework of the "Africa's Study on Physical Activity and Dietary Assessment Methods" (AS-PADAM) project. It involves international institutional and African networks. An inventory questionnaire was developed and disseminated through the networks. Eighteen countries responded to the dietary inventory questionnaire. RESULTS: Various DA tools were reported in Africa; 24-Hour Dietary Recall and Food Frequency Questionnaire were the most commonly used tools. Few tools were validated and tested for reliability. Face-to-face interview was the common method of administration. No computerized software or other new (web) technologies were reported. No tools were standardized across countries. CONCLUSIONS: The lack of comparable DA methods across represented countries is a major obstacle to implement comprehensive and joint nutrition-related programmes for surveillance, programme evaluation, research, and prevention. There is a need to develop new or adapt existing DA methods across countries by employing related research infrastructure that has been validated and standardized in other settings, with the view to standardizing methods for wider use.

RESUMO

BACKGROUND: Studies investigating dietary resemblance between parents and their children have gained mixed results, and the resemblance seems to vary across nutrients, foods, dietary-assessment tools used, and parent-child pairs. We investigated parent-child dietary resemblance using a novel approach in applying statistical analysis, which allowed the comparison of 'whole-diet' between parents and their children. Additionally, we sought to establish whether sociodemographic factors or family meals were associated with dietary resemblance and whether parent-child dietary resemblance was dependent on the parent providing food consumption data on behalf of the child (father or mother, "the respondent"). METHODS: The DAGIS study investigated health behaviors among Finnish preschoolers using a cross-sectional design. One parent filled in a food frequency questionnaire (FFQ) measuring the child's food consumption outside preschool hours during the last week. In addition, we instructed both parents or legal guardians, should the child have two, to fill in a similar FFQ regarding their own food use. Parents also reported their educational level, the number of children living in the same household, and the number of family meals. As a measure of dietary resemblance between a parent and a child, we computed Spearman correlations ranging mostly from no resemblance (0) to complete resemblance (+ 1) between parent-child pairs over the 'whole-diet' (excluding preschool hours). These resemblance measures were further investigated using linear mixed models. RESULTS: We obtained 665 father-child and 798 mother-child resemblance measures. Mother-child resemblance was on average 0.57 and stronger than father-child resemblance (0.50, p < 0.0001), which was explained by a parent-respondent interaction: the diet of the child resembled more the diet of the parent who provided food consumption data for the child. In univariate models, father- and mother-reported number of family meals were positively associated with father-child and mother-child resemblances. Mother-reported number of family meals was positively associated with mother-child resemblance in a full model. CONCLUSIONS: The diet of the child seems to resemble more the diet of the parent responsible for the reporting of food consumption. Studies should report who provided the food consumption data for the child and take this into account in analyses, since reporter-bias can influence the results.

RESUMO

OBJECTIVE: The objective of the present study was to explore whether dietary patterns (DP) are associated with nutritional status indicators among adolescent Mozambican girls. Design/Setting/Subjects In this population-based cross-sectional study we used the FFQ data of 547 girls aged 14-19 years from Central Mozambique to derive dietary patterns by means of principal component analysis. We used two-level linear regression models to examine the associations between the DP and anthropometric and biochemical indicators of nutritional status. RESULTS: We identified three DP: 'Urban bread and fats', 'Rural meat and vegetables' and 'Rural cassava and coconut'. The 'Urban bread and fats' DP was positively associated with BMI-for-age Z-score (BMIZ), mid-upper arm circumference (MUAC), triceps skinfold (P for all<0·001) and blood Hb (P=0·025). A negative association was observed between the 'Urban bread and fats' DP and serum folate (P<0·001). The 'Rural meat and vegetables' DP and the 'Rural cassava and coconut' DP were associated negatively with BMIZ, MUAC and triceps skinfold (P for all<0·05), but the 'Rural meat and vegetables' DP was associated positively with serum ferritin (P=0·007). CONCLUSIONS: Urban and rural DP were associated with nutritional status indicators. In a low-resource setting, urban diets may promote body fat storage and blood Hb concentrations but compromise serum folate concentration. It is important to continue valuing the traditional, rural foods that are high in folate.

RESUMO

OBJECTIVE: To study the associations between home food availability and dietary patterns among pre-school children. DESIGN: Cross-sectional study in which parents of the participating children filled in an FFQ and reported how often they had certain foods in their homes. We derived dietary pattern scores using principal component analysis, and composite scores describing the availability of fruits and vegetables as well as sugar-enriched foods in the home were created for each participant. We used multilevel models to investigate the associations between availability and dietary pattern scores. SETTING: The DAGIS study, Finland. SUBJECTS: The participants were 864 Finnish 3-6-year-old children recruited from sixty-six pre-schools. The analyses included 711 children with sufficient data. RESULTS: We identified three dietary patterns explaining 16·7 % of the variance. The patterns were named 'sweets-and-treats' (high loadings of e.g. sweet biscuits, chocolate, ice cream), 'health-conscious' (high loadings of e.g. nuts, natural yoghurt, berries) and 'vegetables-and-processed meats' (high loadings of e.g. vegetables, cold cuts, fruit). In multivariate models, the availability of fruits and vegetables was inversely associated with the sweets-and-treats pattern (ß=-0·05, P<0·01) and positively associated with the health-conscious (ß=0·07, P<0·01) and vegetables-and-processed meats patterns (ß=0·06, P<0·01). The availability of sugar-enriched foods was positively associated with the sweets-and-treats pattern (ß=0·10, P<0·01) and inversely associated with the health-conscious pattern (ß=-0·03, P<0·01). CONCLUSIONS: Considering dietary patterns, the availability of sugar-enriched foods in the home seems to have a stronger role than that of fruits and vegetables. Parents should restrict the availability of unhealthy foods in the home.

RESUMO

PURPOSE: In low-income settings, dietary diversity scores (DDSs) often predict the micronutrient adequacy of diets, but little is known about whether they predict levels of biochemical indicators of micronutrient status. METHODS: In 2010, we studied two samples of non-pregnant 14- to 19-year-old girls in central Mozambique, the first in January-February ('hunger season'; n = 227) and the second in May-June (harvest season; n = 223). In this paper, we examined whether a low Women's Dietary Diversity Score (WDDS) predicts a low concentration of haemoglobin, serum ferritin, zinc, and folate, and plasma retinol in adolescent Mozambican girls. We constructed three scores: WDDS based on 24-h recalls, WDDS15g based on 24-h recall and employing a 15 g limit, and 7dWDDS based on 7-day food frequency questionnaires. Logistic regression models, stratified by season, were used to estimate the odds of having a low concentration of a status indicator (≤25th percentile of the season-specific distribution or cut-off from the literature) in those with a low score compared to those with a higher score. RESULTS: In January-February, after adjusting for confounders, a low (≤3) WDDS and a low (≤5) 7dWDDS were each associated with higher odds of having low serum zinc compared to having a higher score, regardless of which of the two types of cut-offs for serum zinc was used. These associations were not present in May-June. CONCLUSIONS: Our data from Mozambique suggest that dietary diversity is associated with serum zinc, but this association seems to be limited to the hunger season.

RESUMO

Many African diets are low in fat but are currently changing because of nutrition transition. We studied fat and fatty acid (FA) intake and the essential fatty acid (EFA) status of adolescent girls (aged 14-19 years, n 262) in Zambezia Province, central Mozambique. A cross-sectional study was carried out in a city as well as in the towns and rural villages of a coastal and an inland district. Dietary intake and FA sources were studied in a 24 h dietary recall. FA compositions of cholesteryl esters and phospholipids of non-fasting serum samples were analysed by GLC. Fat intake was low (13-18 % of energy) in all areas. Coconut and palm oil were the main sources of fat, and soyabean oil and maize were the main sources of PUFA. Compared to Food and Agriculture Organization/WHO 2010 recommendations, intake of linoleic acid (LA, 18 : 2n-6) was inadequate in the coastal district, and intakes of n-3 PUFA were inadequate in all areas. FA compositions of serum lipids differed between areas. The proportions of LA tended to be highest in the city and lowest in the rural areas. The phospholipid mead (20 : 3n-9):arachidonic acid (20 : 4n-6) ratio did not indicate EFA insufficiency. LA proportions in phospholipids were low, but those of long-chain n-6 and n-3 PUFA were high in comparison with Western adolescents. To conclude, fat sources, FA intake and EFA status differed between adolescent girls living in different types of communities. Fat intake was low, but EFA insufficiency was not indicated.

RESUMO

OBJECTIVE: To assess the validity of food photographs in portion size estimation among adolescent girls in Mozambique. The study was carried out in preparation for the larger ZANE study, which used the 24 h dietary recall method. DESIGN: Life-sized photographs of three portion sizes of two staple foods and three sauces were produced. Participants ate weighed portions of one staple food and one sauce. After the meal, they were asked to estimate the amount of food with the aid of the food photographs. SETTING: Zambezia Province, Mozambique. SUBJECTS: Ninety-nine girls aged 13­18 years. RESULTS: The mean differences between estimated and actual portion sizes relative to the actual portion size ranged from 219% to 8% for different foods. The respective mean difference for all foods combined was 25% (95% CI 212, 2 %). Especially larger portions of the staple foods were often underestimated. For the staple foods, between 62% and 64% of the participants were classified into the same thirds of the distribution of estimated and actual food consumption and for sauces, the percentages ranged from 38% to 63%. Bland­Altman plots showed wide limits of agreement. CONCLUSIONS: Using life-sized food photographs among adolescent Mozambican girls resulted in a rather large variation in the accuracy of individuals' estimates. The ability to rank individuals according to their consumption was, however, satisfactory for most foods. There seems to be a need to further develop and test food photographs used in different populations in Sub-Saharan Africa to improve the accuracy of portion size estimates.

RESUMO

An adequate alpha-tocopherol status is important for females at reproductive age. We studied the dietary intake and sources of alpha-tocopherol and alpha- and gamma-tocopherol status indicators in 14-19-year-old girls in Central Mozambique. We also explored factors associated with alpha- and gamma-tocopherol status. The participants (n 508) were from the cross-sectional ZANE Study that was conducted in 2010. We recruited two separate samples, one in January-February and the other in May-June. We collected venous blood samples and conducted 24 h dietary recall interviews. At the time of blood sampling, 11 % of participants were pregnant and 10 % were lactating. In the total sample, both seasons combined, the median intake of alpha-tocopherol was 6⋅7 mg/d, the mean plasma alpha- and gamma-tocopherol concentrations were 13⋅5 and 0⋅75 µmol/l, respectively, and the prevalence of vitamin E inadequacy (alpha-tocopherol <12 µmol/l) was 36⋅7 % (95 % CI: 31⋅9-42⋅0 %). Season and lactation status were significant predictors of alpha-tocopherol status regardless of which the three indicators (plasma concentration, alpha-tocopherol:total cholesterol ratio, gamma-tocopherol:alpha-tocopherol ratio) were used. Being a lactating mother was negatively associated and having a blood sample taken in January-February, when the main sources of alpha-tocopherol were mango and dark green leafy vegetables, was positively associated with alpha-tocopherol status. In conclusion, vitamin E inadequacy was common in Central Mozambique, and the status may fluctuate due to seasonal changes in the diet. We suggest that lactating mothers are specifically at risk of poor alpha-tocopherol status in resource-poor settings.

RESUMO

BACKGROUND: Although research has linked children's temperament with weight outcomes, the associations between temperament and dietary outcomes, particularly energy intake, remain understudied. Furthermore, little is known about how temperament is associated with diet in the early childhood education and care (ECEC) context, which is an important environment for many children. OBJECTIVES: This study examined whether temperament is associated with mean energy intake and its day-to-day variability. In addition, the associations were examined separately in the contexts of home and ECEC. METHODS: The study used data from 505 Finnish children from a cross-sectional DAGIS study conducted in 2015-2016. Parents reported their child's temperament with a questionnaire and food consumption with a food record for two weekdays (outside daycare hours) and one weekend day. Early educators at an ECEC centre reported the child's food consumption during the daycare hours on the same weekdays as the parents kept food records at home. Associations were examined with linear regression models. RESULTS: Children with higher surgency had a higher mean daily energy intake. When examined separately at home and in the ECEC centre, the association was found only in the ECEC centre. Children with higher negative affectivity had greater day-to-day variability in energy intake. This association, however, was not observed when examined separately at home and at the ECEC centre. CONCLUSIONS: The results indicate that temperament may shape children's energy intake. Moreover, the role of the ECEC context in children's eating may be different depending on a child's temperamental dispositions, which warrants further research.

RESUMO

OBJECTIVE: To investigate the purchase and use of fortified foods, and to explore and compare background characteristics, food consumption and nutrient intakes among users and non-users of voluntarily fortified foods in Finland. DESIGN: A study based on the National FINDIET Survey 2007 (48 h recall), which included also a barcode-based product diary developed to assess the type, amount and users of voluntarily fortified foods. Logistic regression analysis was employed to investigate associations between background characteristics and the use of fortified foods. SETTING: Randomly chosen subgroup of 918 adult participants in the National FINDIET 2007 Survey. SUBJECTS: Men and women aged 25-64 years from five regions. RESULTS: The product group of voluntarily fortified foods purchased in the highest volume was yoghurts (44 % of the weight of all fortified food), followed by fruit drinks (36 %). The only characteristics independently associated with the use of voluntarily fortified foods were age (older people used them less commonly) and the consumption of fruit and vegetables (participants with the highest consumption used them more commonly). Users of fortified foods had higher consumption of yoghurt, juice drinks and ready-to-eat breakfast cereals (women only) than non-users, and lower consumption of boiled potatoes (men only). CONCLUSIONS: Use of voluntarily fortified foods is associated with high consumption of fruit and vegetables but not with other health-related behaviours. The use of voluntarily fortified foods does not seem to even out the differences in nutrient intake among Finnish adults.

RESUMO

Global food systems face the challenge of providing healthy and adequate nutrition through sustainable means, which is exacerbated by climate change and increasing protein demand by the world's growing population. Recent advances in novel food production technologies demonstrate potential solutions for improving the sustainability of food systems. Yet, diet-level comparisons are lacking and are needed to fully understand the environmental impacts of incorporating novel foods in diets. Here we estimate the possible reductions in global warming potential, water use and land use by replacing animal-source foods with novel or plant-based foods in European diets. Using a linear programming model, we optimized omnivore, vegan and novel food diets for minimum environmental impacts with nutrition and feasible consumption constraints. Replacing animal-source foods in current diets with novel foods reduced all environmental impacts by over 80% and still met nutrition and feasible consumption constraints.

RESUMO

Vegan diets are gaining popularity, also in families with young children. However, the effects of strict plant-based diets on metabolism and micronutrient status of children are unknown. We recruited 40 Finnish children with a median age 3.5 years-vegans, vegetarians, or omnivores from same daycare centers-for a cross-sectional study. They enjoyed nutritionist-planned vegan or omnivore meals in daycare, and the full diets were analyzed with questionnaires and food records. Detailed analysis of serum metabolomics and biomarkers indicated vitamin A insufficiency and border-line sufficient vitamin D in all vegan participants. Their serum total, HDL and LDL cholesterol, essential amino acid, and docosahexaenoic n-3 fatty acid (DHA) levels were markedly low and primary bile acid biosynthesis, and phospholipid balance was distinct from omnivores. Possible combination of low vitamin A and DHA status raise concern for their visual health. Our evidence indicates that (i) vitamin A and D status of vegan children requires special attention; (ii) dietary recommendations for children cannot be extrapolated from adult vegan studies; and (iii) longitudinal studies on infant-onset vegan diets are warranted.

RESUMO

The study examines the effects of a preschool-based family-involving multicomponent intervention on children's energy balance-related behaviors (EBRBs) such as food consumption, screen time and physical activity (PA), and self-regulation (SR) skills, and whether the intervention effects differed among children with low or high parental educational level (PEL) backgrounds. The Increased Health and Wellbeing in Preschools (DAGIS) intervention was conducted as a clustered randomized controlled trial, clustered at preschool level, over five months in 2017-2018. Altogether, 802 children aged 3-6 years in age participated. Parents reported children's consumption of sugary everyday foods and beverages, sugary treats, fruits, and vegetables by a food frequency questionnaire, and screen time by a 7-day diary. Physical activity was assessed by a hip-worn accelerometer. Cognitive and emotional SR was reported in a questionnaire by parents. General linear mixed models with and without repeated measures were used as statistical methods. At follow-up, no differences were detected in EBRBs or SR skills between the intervention and control group, nor did differences emerge in children's EBRBs between the intervention and the control groups when stratified by PEL. The improvement in cognitive SR skills among low PEL intervention children differed from low PEL control children, the significance being borderline. The DAGIS multicomponent intervention did not significantly affect children's EBRBs or SR. Further sub-analyses and a comprehensive process evaluation may shed light on the non-significant findings.
