A tendency toward evening chronotype associates with less healthy diet among preschoolers: cross-sectional findings from the DAGIS study.

Study Objectives: Evidence suggests that adolescents and adults with a later chronotype have poorer sleep habits and are more susceptible to unhealthy behaviors, but little is known about these associations in younger children. The objective of the study was to (1) identify and compare individual chronotype tendencies among preschool-aged children and (2) investigate associations of sleep dimensions and chronotype with diet. Methods: Participants were 636 3-6 years old (mean ±â€…SD age: 4.74 ±â€…0.89 years, 49% girls) preschoolers from the cross-sectional Increased Health and Well-Being in Preschoolers (DAGIS) study in Finland. Sleep duration, sleep variability (in duration and midpoint), social jetlag, and midsleep on weekends adjusted for sleep debt (MSWEadj) were measured with 7-day actigraphy. Morning, intermediate, and evening chronotype tendencies were defined based on the lowest and highest 10th percentile cutoffs of MSWEadj. Food, energy, and macronutrient intake were assessed from 3-day records. Associations between sleep dimensions and diet were assessed with regression models. Results: MSWEadj was 1:13 ±â€…14 minutes for morning (n = 64), 2:25 ±â€…28 minutes for intermediate (n = 560), and 3:38 ±â€…15 minutes for evening (n = 64) chronotype tendency. Children with an evening chronotype tendency had greater social jetlag and sleep variability. Having an evening chronotype tendency was associated with higher added sugar, higher sugary food consumption, and lower vegetable consumption compared to intermediate tendency types. A later chronotype (MSWEadj) was associated with higher sugary food consumption, as well as lower vegetable and fiber intake. Sleep duration, social jetlag, and sleep variability were not associated with diet. Conclusions: Several less healthy sleep and diet behaviors were observed among children with later chronotypes. Future public health interventions aimed towards children would benefit from taking into account chronotype.

How energy balance-related behaviours, temperament, stress and overweight associate: a cross-sectional study of Finnish preschoolers.

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.

Comparison of actigraphy-measured and parent-reported sleep in association with weight status among preschool children.

This study compared weekday and weekend actigraphy-measured and parent-reported sleep in relation to weight status among preschool-aged children. Participants were 3-6 years old preschoolers from the cross-sectional DAGIS-study with sleep data for ≥2 weekday and ≥2 weekend nights. Parents-reported sleep onset and wake-up times were gathered alongside 24 h hip-worn actigraphy. An unsupervised Hidden-Markov Model algorithm provided actigraphy-measured night time sleep without the guidance of reported sleep times. Waist-to-height ratio and age-and-sex-specific body mass index characterised weight status. Comparison of methods were assessed with consistency in quintile divisions and Spearman correlations. Associations between sleep and weight status were assessed with adjusted regression models. Participants included 638 children (49% girls) with a mean ± SD age of 4.76 ± 0.89. On weekdays, 98%-99% of actigraphy-measured and parent-reported sleep estimates were classified in the same or adjacent quintile and were strongly correlated (rs = 0.79-0.85, p < 0.001). On weekends, 84%-98% of actigraphy-measured and parent-reported sleep estimates were respectively classified and correlations were moderate to strong (rs = 0.62-0.86, p < 0.001). Compared with actigraphy-measured sleep, parent-reported sleep had consistently earlier onset, later wake-up, and greater duration. Earlier actigraphy-measured weekday sleep onset and midpoint were associated with a higher body mass index (respective ß-estimates: -0.63, p < 0.01 and -0.75, p < 0.01) and waist-to-height ratio (-0.004, p = 0.03 and -0.01, p = 0.02). Though the sleep estimation methods were consistent and correlated, actigraphy measures should be favoured as they are more objective and sensitive to identifying associations between sleep timing and weight status compared with parent reports.

Food consumption and nutrient intake of Finnish preschool children according to parental educational level.

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.

Association of the timing of evening eating with BMI Z-score and waist-to-height ratio among preschool-aged children in Finland.

Later timing of eating has been associated with higher adiposity among adults and children in several studies, but not all. Moreover, studies in younger children are scarce. Hence, this study investigated the associations of the timing of evening eating with BMI Z-score and waist-to-height ratio (WHtR), and whether these associations were moderated by chronotype among 627 preschoolers (3-6-year-olds) from the cross-sectional DAGIS survey in Finland. Food intake was measured with 3-d food records, and sleep was measured with hip-worn actigraphy. Three variables were formed to describe the timing of evening eating: (1) clock time of the last eating occasion (EO); (2) time between the last EO and sleep onset; and (3) percentage of total daily energy intake (%TDEI) consumed 2 h before sleep onset or later. Chronotype was assessed as a sleep debt-corrected midpoint of sleep on the weekend (actigraphy data). The data were analysed with adjusted linear mixed effects models. After adjusting for several confounders, the last EO occurring closer to sleep onset (estimate = -0·006, 95 % CI (-0·010, -0·001)) and higher %TDEI consumed before sleep onset (estimate = 0·0004, 95 % CI (0·00003, 0·0007)) were associated with higher WHtR. No associations with BMI Z-score were found after adjustments. Clock time of the last EO was not significantly associated with the outcomes, and no interactions with chronotype emerged. The results highlight the importance of studying the timing of eating relative to sleep timing instead of only as clock time.

Role of early childhood educators' demographic characteristics and perceived work environment in implementation of a preschool health promotion intervention.

BACKGROUND: Research has indicated that the effectiveness of intervention programs is affected by how well these programs are implemented, but key gaps remain in our understanding of the factors that promote or inhibit implementation. This study examined how demographic characteristics and perceived work environment among early childhood educators were associated with implementation outcomes of the Increased Health and Wellbeing in Preschools (DAGIS) intervention, which was conducted as a cluster randomized trial. METHODS: Participants included 101 educators from 32 intervention preschool classrooms. Data were analyzed at the classroom level, as the DAGIS intervention was delivered in preschool classrooms consisting of several educators instead of individual implementers. Linear regression was used to estimate the associations of educators' demographic characteristics and perceived work environment with different aspects of implementation (i.e., dose delivered; dose received - exposure; dose received - satisfaction; and perceived quality, as well as a total sum score based on these four dimensions). Municipality was controlled in the adjusted models. RESULTS: Findings indicated that having a higher proportion of educators with a Bachelor's or Master's degree in education within the classroom was associated with higher dose received - exposure and higher total degree of implementation, and the significance of the models was unaffected by adjustment for municipality. Moreover, having a higher proportion of educators younger than 35 years within the classroom was associated with higher dose received - exposure. However, the association was non-significant when adjusted for municipality. No other educator factor (i.e., work experience in years and perceived support from coworkers, group work, and innovative climate) predicted implementation outcomes. CONCLUSIONS: Higher educational attainment and younger age among educators at the classroom level were associated with higher scores for some of the implementation outcomes. Educators' work experience in years at the current preschool and in early childhood education, support from coworkers, group work, and innovative climate were not significantly associated with any implementation outcomes. Future research should explore ways to improve educators' implementation of interventions aimed at promoting children's health behaviors.

Child temperament is associated with energy intake and its day-to-day variability among preschoolers-Results from a cross-sectional DAGIS study.

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.

Associations between socioeconomic status, home food availability, parental role-modeling, and children's fruit and vegetable consumption: a mediation analysis.

BACKGROUND: Recent literature has suggested that associations and interactions between family socioeconomic status (SES) and home food environment influence children's diet, but little is known about the mediation roles of parental role-modeling and food availability in the socioeconomic inequalities of children's diet. This study aimed to determine the associations between family SES and children's fruit and vegetable (FV) consumption and to assess the mediation roles of parental role-modeling and food availability in the above associations. METHODS: Cross-sectional data of 574 Finnish children (aged 3 to 6) were analyzed. Parents completed an FFQ assessing their children's FV consumption frequency and a questionnaire assessing SES and home food environment. Two exposure variables: parental educational level ("low", "middle", and "high") and the relative family income tertiles of the family were used. The frequencies of parental role-modeling of FV and sugary food and drink (SFD) consumption, and the availability of FV and SFD at home were calculated. Single- and multiple-mediator models were created using IBM SPSS 27.0. RESULTS: The positive association between high parental educational level and children's FV consumption (direct effect coefficient: 2.76, 95% CI: 0.51-4.86) was partially mediated by more frequent parental role-modeling of FV consumption (indirect effect coefficient: 0.89, 95% CI: 0.10-1.76), higher availability of FV (indirect effect coefficient: 1.00, 95% CI: 0.35-1.77), and lower availability of SFD (indirect effect coefficient: -0.30, 95% CI: -0.72 - -0.01). The relative family income was not directly associated with the outcome. However, the higher relative family income level indirectly predicted the Children's FV consumption (full mediation) through more frequent parental role-modeling of FV consumption (indirect effect coefficient: 0.91, 95% CI: 0.06-1.83) and higher availability of FV (indirect effect coefficient: 0.98, 95% CI: 0.40-1.67). Parental role-modeling on SFD consumption did not mediate any of the above associations. CONCLUSIONS: Parental educational level showed more associations with children's FV consumption than relative family income. Our findings suggest that reducing the availability of SFD is as important as increasing the availability of FV to enhance children's FV consumption. Future interventions to improve children's dietary behaviors should pay greater attention to the lower SES segments of society. Longitudinal studies and intervention studies supporting these findings are needed for making meaningful recommendations for health promotion.

The role of parental congruence in pre-school children's screen time, moderated by parental education.

AIM: This study investigated whether parental congruency regarding screen time (ST) is associated with ST in pre-school children. In addition, we investigated whether parental education levels moderated this relationship. METHODS: A cross-sectional study was conducted in 2015-2016 in Finland (N = 688). Parents completed a questionnaire reporting their children's sedentary behaviour, their parental congruency regarding ST rules, and their educational level. Associations were examined using linear regression. RESULTS: Children of parents with higher congruence regarding ST rules engaged in less ST, this was moderated by parental education levels. Children whose parents had a high level of education and parents' who strongly agree or somewhat agree on ST rules was negatively associated with ST. Furthermore, children whose parents had a medium level of education and parents' who strongly agree on ST rules was negatively associated with ST. CONCLUSION: Children of parents who agree on ST rules engaged in less ST compared with children of parents who do not agree on ST rules. Providing advice to parents regarding parental congruency could be the focus of future interventions.

Effects of the DAGIS randomized controlled trial on home environment and children's food consumption according to the degree of implementation.

BACKGROUND: Combining process evaluation data with effectiveness data and examining the possible mediators of intervention effects elicits valuable knowledge about how and for whom these interventions are effective. The aim of this study was to examine whether the parental degree of implementation (DOI) of a home-involving preschool intervention affected children's food consumption via home mediators. METHODS: The five-month Increased Health and Wellbeing in Preschools (DAGIS) intervention involved 476 participating children aged 3-6 years and was conducted in 2017-2018. Parents reported children's food consumption (g/day) outside childcare hours, the availability of foods at home, role modelling of food consumption, and the norms related to food consumption. In addition, parents reported the extent to which they had implemented the intervention program at home. Mediation analyses were conducted to examine the effect of low and high DOI compared to control group on the change in children's consumption of fruit and vegetables (FV), sugary everyday foods, sugary treats, and sugar-sweetened beverages (SSB) via food availability in the home, parental role modelling and parental norms. RESULTS: Compared to the control group, there was a direct effect of a high DOI on diminishing consumption of SSB (B -27.71, 95% CI -49.05, -4.80). No indirect effects were detected. In the high DOI group, a change in parental norm was associated with increased FV consumption showing an indirect effect (B 4.31, 95% CI 0.23, 10.59). In the low DOI group, there was an indirect effect via decreased food availability leading to decreased sugary everyday food consumption (B -2.17, 95% CI -5.09,  -0.09). CONCLUSIONS: Combining process evaluation and effectiveness data revealed a decrease in children's SSB consumption only in the high DOI group, as well as indirect effects on children's consumption of FV and sugary everyday foods. In order to gain more intervention effects, further studies are required in order to examine parental facilitators and barriers to the implementation of interventions and how to impact effectively the determinants of the targeted behavior.

Sustainability analysis of Finnish pre-schoolers' diet based on targets of the EAT-Lancet reference diet.

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.

Associations between hair and salivary cortisol, salivary alpha-amylase, and temperament dimensions among 3-6-year-olds.

Associations between hair cortisol concentration (HCC), diurnal salivary cortisol (sCort) and alpha-amylase (sAA), and temperament dimensions were examined among 3-6-year-old Finnish children (n = 833). Children's hair samples were collected at preschool, while parents collected five saliva samples from children during one weekend day and completed a questionnaire assessing child's temperament dimensions i.e. surgency, negative affectivity, and effortful control (HCC, n = 677; AUCg of sAA, n = 380; AUCg of sCort, n = 302; temperament dimensions, n = 751). In linear regression analysis, diurnal sCort associated positively with HCC, the association persisting after adjustments (ß 0.31, 95% CI 0.20-0.42). In logistic regression analysis, increasing scores in effortful control associated with higher likelihood of having high HCC (OR 1.47, 95% CI 1.07-2.03), the association slightly attenuating to non-significant after adjustments. Otherwise, no clear indication for associations between temperament and stress-related biomarkers were found.

Does temperament make children differently susceptible to their home physical food environment? A cross-sectional DAGIS study on 3-6 year old Finnish children's food consumption.

Consistently linked with children's food consumption are food availability and accessibility. However, less is known about potential individual differences among young children in their susceptibility to home food environments. The purpose of the study was to examine whether the association between home food availability and accessibility of sugar-rich foods and drinks (SFD) or fruits and vegetables (FV) and children's consumption of these foods differ according to their temperament. The study used two cross-sectional datasets collected as part of the Increased Health and Wellbeing in Preschools (DAGIS) study: 1) a cross-sectional data of 864 children aged 3-6 years old collected between fall 2015 and spring 2016, and 2) an intervention baseline data of 802 children aged 3-6 collected in fall 2017. Parents reported their children's temperament, consumption of FV and SFD, and home availability and accessibility of SFD and FV. Examination of whether associations between home availability and accessibility of FV and their consumption differ according to children's temperament involved using linear regression models. Similar models were used to examine association between home availability and accessibility of SFD and their consumption, and the moderating role of temperament. The association between home accessibility of SFD and their consumption frequency was dependent on the level of children's negative affectivity. More frequent consumption of SFD was observed with higher home accessibility of SFD. The association was stronger in children with higher scores in negative affectivity. No other interactions were found. Children with higher negative affectivity are possibly more vulnerable to food cues in the home environment than children with lower negative affectivity. Consideration of children's individual characteristics is necessary in supporting their healthy eating.

Are associations between home environment and preschool children's sedentary time influenced by parental educational level in a cross-sectional survey?

BACKGROUND: Childhood obesity is a major public health concern, especially in low socioeconomic groups. Sedentary time (SED) is an important predictor of obesity. To be able to diminish SED it is important to find modifiable predictors of sedentary behavior. The home environment associated with children's SED may vary by parental socioeconomic status. This study aims to clarify the association between parental educational level (PEL) and the home environment of 3-6-year-old children, and to examine how home environment associates with children's SED, and whether PEL modifies these associations. METHODS: A cross-sectional Increased health and wellbeing in preschools (DAGIS) study was conducted in 2015-2016 in Finland. The parents (n = 809) filled in questionnaires assessing PEL, and the home physical and social environment related to children's SED. Children's SED was measured with accelerometers, which the children (n = 745) wore for 1 week. RESULTS: High PEL was associated with a home environment restraining sedentary behaviour compared with low PEL. Stricter descriptive norms about screen time, considering it important to limit the child's screen time, and satisfaction about the child's screen time associated with children's lower SED. The association with parental psychological control and SED was influenced by PEL. In the PEL stratified analyses, however, the associations between psychological control and SED did not reach statistical significance. CONCLUSIONS: Future interventions aiming to decrease SED should pay attention to relevant factors in children's sedentary behaviour home environment. It is important to acknowledge the possible PEL differences in these factors.

Effects of the Preschool-Based Family-Involving DAGIS Intervention on Family Environment: A Cluster Randomised Trial.

Interventions promoting young children's healthy energy balance-related behaviours (EBRBs) should also examine changes in the family environment as this is an important determinant that may affect the effectiveness of the intervention. This study examines family environmental effects of the Increased Health and Wellbeing in Preschools (DAGIS) intervention study, and whether these effects differed when considering three parental educational level (PEL) groups. The DAGIS intervention was conducted in preschools and involving parents in Southern Finland from September 2017 to May 2018. It was designed as a randomised trial, clustered at preschool-level. Parents of 3-6-year-olds answered questionnaires recording PEL, parental role modelling for EBRBs, and the family environment measured as EBRBs availability and accessibility. Linear Mixed Models with Repeated Measures were used in order to detect intervention effects. Models included group by time interactions. When examining intervention effects separated by PEL groups, models with three-level interactions (group × time-points × PEL) were evaluated. There was an interaction effect for the availability of sugary everyday foods and drinks (p = 0.002). The analyses showed that the control group increased availability (p = 0.003), whereas in the intervention group no changes were detected (p = 0.150). In the analysis separated by PEL groups, changes were found only for the accessibility of sugary treats at home; the high PEL control group increased the accessibility of sugary treats (p = 0.022) (interaction effect: p = 0.027). Hence, results suggest that the DAGIS multicomponent intervention had a limited impact on determinants for children's healthy EBRBs, and no impact was found in the low PEL group.

Effects of the Preschool-Based Family-Involving DAGIS Intervention Program on Children's Energy Balance-Related Behaviors and Self-Regulation Skills: A Clustered Randomized Controlled Trial.

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.

Preschool group practices and preschool children's sedentary time: a cross-sectional study in Finland.

OBJECTIVES: Preschool is an important setting for regulating sedentary time (ST). The preschool day in Finland follows daily structures by having morning and afternoon slots for group-based activities that can encourage children for movement (eg, free play and outdoor time) or be still (eg, teacher-led sessions and sitting-based circles). This study aims to explore if the weekly routines in preschool and if more frequent visits in places encouraging physical activity (PA) are associated with children's ST during preschool hours. DESIGN: Cross-sectional DAGIS (Increased Health and Wellbeing in Preschools) study in the years 2015 and 2016. SETTING: In Finland. PARTICIPANTS: 864 children (48% girls, 4.7 years) from 159 preschool groups in 66 preschools OUTCOME MEASURES: A total of 778 children wore required lengths of time (at least 240 min per preschool day, at least 2 days) the accelerometer during preschool hours. Each preschool group reported their weekly schedule during the week, and one early educator completed a questionnaire covering practices. The following five measures related to weekly structures were formed; times of outdoors (times per day), teacher-led sessions (times per day), free play (low, middle or high), organised PA lessons (no lessons at all/others) and mixed activities (no lessons at all/others), and the following five measures about the frequencies of visits in places encouraging PA; nature trips (times per week), play parks (times per week), neighbourhood sport facilities (no visits at all/others), visits to gym or other indoor facility (no visits at all/others) and field trips to neighbourhoods (times per week). Multilevel linear regression analyses were conducted to measure the associations. RESULTS: Of all the tested associations, only more frequently conducted nature trips were associated with lower children's ST during preschool hours (ß=-1.026; 95% CI -1.804 to -0.248). CONCLUSION: Frequent nature trips in preschools may be important due to its association with lower preschool children's ST.

The Contribution of Preschool Meals to the Diet of Finnish Preschoolers.

Preschool meals may influence the formation of children's dietary habits and health. We assessed the contribution of preschool meals to the diet of Finnish children. We used food record data from the cross-sectional DAGIS survey and selected recording days which included all three meals (breakfast, lunch, afternoon snack) at preschool. We analyzed the diet of three- to four-year-olds (n = 324) and five- to six-year-olds (n = 233). Preschool meals accounted for 54% of the weekday's energy intake in both age groups, and provided ≥60% of total fiber, polyunsaturated fatty acids, and vitamins D and E. More than 60% of fish dishes but only one third of total daily fresh fruit were consumed at preschool. The mean (SD) percentages of energy from protein and fat at preschool were 17% (3%) and 30% (7%) in the younger and 17% (3%) and 31% (6%) in the older age group, respectively. The mean proportions of energy from added sugar at preschool were below 5% in both age groups. On average, salt intake exceeded recommendations and 60% of salt came from preschool food. Tackling high salt intake should be a future goal of guidance for early childhood education and care food services.

Fruit, Vegetable, and Fibre Intake among Finnish Preschoolers in Relation to Preschool-Level Facilitators and Barriers to Healthy Nutrition.

Preschool is a major factor affecting food consumption among young children in Finland, given that most preschoolers eat three meals a day in that setting. Thus, it is important to recognise the determinants of dietary intake at preschool. The aim of this study was to examine food-related factors at the preschool and manager level, and their association with the dietary intake of children in childcare. The study was a part of the cross-sectional DAGIS survey conducted in 2015 to 2016 in Finland. The managers of 58 preschools filled in a questionnaire related to food and nutrition at their preschools. Preschool personnel kept food records for the children (n = 585) on two preschool days. Multilevel linear and logistic regression analyses were conducted with age, gender, and municipality as covariates, preschool-level factors as independent variables, and children's vegetable (g/day) and fruit (yes vs. no) consumption and fibre intake (g/MJ) as outcome variables. Having many written food policies in the preschool was associated with a higher intake of vegetables (p = 0.01) and fibre (p = 0.03) among the children. Having at least two out of three cooperation-related challenges with the catering service was associated with a higher intake of fibre (p = 0.03) and lower odds of eating fruit (p = 0.01). Factors that are relatively distal from meal situations may have an effect, and should be taken into account in the promotion of healthy eating at preschool, but more studies are needed.

Neighborhood Socioeconomic Status and Feeding Practices in Finnish preschools.

Aims: Certain feeding practices, such as role modeling healthy eating and encouragement are recommended to be used in preschools. Little is known about whether preschool characteristics are associated with the use of these feeding practices. Our aim was to examine whether the socioeconomic status (SES) of the preschool neighborhood is associated with the feeding practices in preschools. Methods: This study was part of the cross-sectional DAGIS study. We studied 66 municipal preschools and 378 early childhood educators (ECEs). Preschool neighborhood SES was assessed with map grid data. Feeding practices were assessed by questionnaires and lunchtime observation. Associations between preschool neighborhood SES and feeding practices were tested with logistic regression analyses adjusted for ECEs' educational level and municipal policies on ECEs' lunch prices, and on birthday foods. Results: The crude model showed that in high-SES neighborhood preschools ECEs were more likely to eat the same lunch as the children (OR 2.46, 95% CI 1.42-4.24) and to reward children with other food for eating vegetables (OR 2.48, 95% CI 1.40-4.41). Furthermore, in high-SES preschools it was less likely that birthday foods outside of the normal menu were available on birthdays (OR 0.29, 95% CI 0.12-0.71). In the adjusted model, rewarding with other food remained associated with preschool neighborhood SES (OR 2.13, 95% CI 1.12-4.07). Conclusions: After adjustments, preschool neighborhood SES was mostly unassociated with the feeding practices in preschools. Municipal policies may have a significant impact on feeding practices and ultimately on young children's food intake in Finland where most children attend municipal preschools.
