    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.

    Screen time is increasing rapidly in young children. The aim of this study was to examine associations of long-term stress and temperament with screen time in Finnish preschool children and the moderating role of socioeconomic status. Cross-sectional DAGIS data were utilized. Long-term stress was assessed using hair cortisol concentration, indicating values of the past 2 months. Temperament was reported by the parents using the Children's Behavior Questionnaire (the Very Short Form), and three broad temperament dimensions were constructed: surgency, negative affectivity, and effortful control. Screen time was reported by the parents over 7 days. The highest education level in the household was used as an indicator of socioeconomic status. In total, 779 children (mean age, 4.7 +/- 0.9 years, 52% boys) were included in the study. Of the temperament dimensions, a higher effortful control was associated with less screen time (B = - 6.70, p = 0.002). There was no evidence for an association between hair cortisol concentration and screen time nor a moderating role of socioeconomic status in the associations (p > 0.05). Conclusion: Our findings indicate that preschool children with a higher score in effortful control had less screen time. Because effortful control reflects general self-regulatory abilities, promoting these skills may be effective in reducing screen time in young children.What is Known: center dot Screen time has increased rapidly during the last decades, and higher screen time has been linked with numerous adverse health consequences in children. center dot There are no previous studies investigating associations of long-term stress and temperament with screen time in young children.What is New: center dot Of the temperament dimensions, effortful control was associated with higher screen time in preschool children, but there was no association found between long-term stress and screen time. center dot Since effortful control reflects general self-regulatory abilities, promoting these skills may be effective in reducing screen time in young children.

    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 (beta 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.

    Whether infant regulatory behavior problems already in the first month of life indicate an increased risk of childhood neurobehavioral problems, and whether maternal depression in the postpartum and early childhood underpins these associations remain unclear. Altogether, 2049-2364 mothers from the Prediction and Prevention of Pre-eclampsia and Intrauterine Growth Restriction (PREDO) study completed the Neonatal Perception Inventory on regulatory behavior problems at the infant's age of 15.6 days (SD 3.2, range 1-30), the Infant Behavior Questionnaire-Revised on temperament at 6.5 months (SD 0.9, range 4.2-12.4), and the Ages and Stages Questionnaire-3 on developmental milestones and the Child Behavior Checklist on behavioral problems at 3.5 years (SD 0.7, range 1.9-6.0). Maternal depressive symptoms were measured by the Center for Epidemiological Studies Depression Scale (infancy follow-ups) and Beck Depression Inventory-II (childhood follow-up). Father-rated infant temperament and paternal depressive symptoms were also available (n = 1474). Higher levels of infant regulatory behavior problems predicted higher levels of mother- and father-rated negative affectivity temperament (0.13 SD units per SD unit, 95% confidence interval 0.09-0.17; and 0.09, 0.04-0.14, respectively), lower levels of mother-rated orienting/regulation temperament (- 0.09, - 0.13 to - 0.05) and problem-solving skills (- 0.12, - 0.21 to - 0.04), and higher levels of Externalizing (0.07, 0.03-0.11) and Total behavioral problems (0.07, 0.03-0.11). Regulatory behaviors partially mediated the effect of maternal depressive symptoms. Regulatory behavior problems already during the first month of life predict neurobehavioral outcomes, and partially mediate the effect of maternal depressive symptoms. Our study may inform design of interventions aimed at timely prevention in children at risk.

    Although temperament and motivation both reflect individual differences in what is perceived as rewarding or threatening, and what is to be approached and what avoided, respectively, we know rather little about how they are connected in educational settings. In this study, we examined how different aspects of temperament (reward and punishment sensitivities) predict the goals students seek to achieve in relation to learning and performance. In Study 1, four dimensions describing students’ temperament (sensitivity to punishment, intraindividual reward sensitivity, interindividual reward sensitivity, and positive expressiveness) were uncovered, and in Study 2, these were used to predict students’ achievement goal orientations (mastery-intrinsic, mastery-extrinsic, performance-approach, performance-avoidance, and avoidance). The results of exploratory structural equation modeling revealed significant predictions on all achievement goal orientations. In line with theoretical assumptions, sensitivity to punishment was predictive of performance orientations, intraindividual reward sensitivity of mastery orientations, and interindividual reward sensitivity of performance- and avoidance orientations. Positive expressiveness only had weak negative effects on performance orientations. The findings suggest that the goals and outcomes students seek to attain in an educational context are partly dictated by their sensitivity to different environmental cues and the kinds of affective and behavioral responses these typically incite.

    Objectives: Cognitive abilities are highly heritable, but several other factors beyond genes also influence the realization of one’s genetic potential. The role of temperament potentially modifying the association between genes and actualized cognitive performance is not well understood. This study examined whether temperament is associated with cognitive performance and whether it modifies an association between genetic cognitive potential and cognitive test performance. Methods: The participants (n = 1,571, 56% female, 35-50 years) were from the population-based Young Finns Study. Temperament was assessed four times (1997, 2001, 2007, and 2012) with the Temperament and Character Inventory’s four dimensions: Novelty Seeking, Harm Avoidance, Reward Dependence and Persistence. Polygenic scores were calculated based on GWA studies to measure the genetic potential for cognitive performance. Cognitive performance was assessed in 2012 with four CANTAB tests: Visual memory, Reaction Time, Sustained Attention and Spatial Working Memory. Results: Temperament did not modify the realization of genetic potential for cognitive performance but had main effects on the performance: High Persistence was associated with higher visual memory, low Harm Avoidance with higher overall cognitive and reaction time performance, while Novelty Seeking and Reward Dependence had insignificant associations. Harm Avoidance’s subscale high Anticipatory Worry was associated with lower overall cognitive and visual memory performance and high Fatigability with lower reaction time and lower sustained attention performance. High Shyness with Strangers preceded higher visual memory performance. High Fear of Uncertainty was associated with lower visual memory, but higher sustained attention performance. Conclusions: Temperament does not seem to give an advantage or hindrance for an individual to realize their genetic potential for cognitive performance. High Persistence appears beneficial for cognitive performance, whereas high Harm Avoidance is detrimental in certain tasks but beneficial in others.

    Background and objectives: Temperament may be associated with eating behaviors over the lifespan. This study examined the association of toddlerhood temperament with dietary behavior and dietary intervention outcomes across 18 years. Methods: The study comprised 660 children (52% boys) from The Special Turku Intervention Project (STRIP), which is a longitudinal randomized controlled trial from the age of 7 months until the age of 20 years (1990-2010). Temperament was assessed using Carey temperament scales when the participants were 2 years of age. Latent profile analysis yielded three temperament groups, which were called negative/low regulation (19% of the children), neutral/average regulation (52%) and positive/high regulation (28%). Dietary behavior was examined from 2 to 20 years of age using food records, which were converted into a diet score (mean= 15.7, SD 4.6). Mixed random-intercept growth curve analysis was the main analytic method. Results: Dietary behavior showed a significant quadratic U-shaped curve over time (B for quadratic association = 0.39, P<.001; B for linear association = 0.09, P = 0.58). Children in the negative/low regulation temperament group had a lower diet score (less healthy diet) across the 18 years compared to children in the neutral/average or in the positive/high regulation group. Temperament was not associated with the rate of change in diet over time. Temperament did not have any interactive effects with the intervention (F [2, 627], P = 0.72). Conclusion: Children with a temperament profile characterized by high negative mood, high irregularity and high intensity in emotion expression constitute a risk group for less healthy eating over the lifespan.

    It has repeatedly been found that temperamental inhibition and low academic achievement are associated with each other: children with cautious and wary or shy behaviour are at risk for low academic achievement. Several suggestions about the mechanism behind this association have been made, these highlighting for example, the fewer learning opportunities of cautious and wary children and more negative interaction between teachers and inhibited children. However, the empirical studies about these mechanisms are rare and, thus, they have remained unclear. This study examined whether children's maths-related self-concept of ability acts as a mediator between their temperamental inhibition and maths performance. 156 children (M-age 7.25 years) were followed during the first grade of primary school. Children's temperamental inhibition was assessed in the beginning of Grade 1. Their maths performance was tested twice, in the beginning and at the end of Grade 1, and their self-concept of ability was measured at the end of Grade 1. The research question was analysed using structural equation modelling. The results showed that children's self-concept of ability did mediate the association between temperamental inhibition and maths performance at Grade 1: that more inhibited children feel they are less capable and competent in maths than less inhibited children, and this contributes to their poorer maths performance. The findings highlight that it is important for teachers and other practitioners to be aware of this effect of temperamental inhibition on self-concept and put effort on promoting positive views of children's competencies and abilities.

    The oxytocin receptor gene (OXTR) may function as a "plasticity gene" that increases or decreases sociability in those individuals susceptible to growing up in a beneficial versus more adverse environment. This study used data from 2289 (55% female) participants from the ongoing prospective Young Finns Study. Maternal emotional warmth was assessed in 1980 when the participants were 3-18 years old. Participants' sociability temperament was measured at five follow-ups, from 1992 to 2012. Emotional warmth in childhood and OXTR genotype were not directly associated with temperamental sociability. We found a nominally significant gene environment interaction (p = .03) suggesting that participants with a genetic profile of rs1042778 T-allele and rs2254298 A-allele are affected high versus low emotional warmth, whereas homozygotes of both G-alleles are unaffected by the same environmental influence. Our findings should be, however, interpreted as a null result as the interaction effect did not survive correction for multiple testing.
