The concurrent and longitudinal associations of temperament and nutritional risk factors in early childhood

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.

Examining links between child temperament and feeding, eating, and weight outcomes: An updated systematic review of the literature

BACKGROUND

Weight outcomes have been associated with child temperament, defined as individual differences in reactivity and self-regulation. The current systematic review aims to provide an updated summary of the evidence linking temperamental negative reactivity, surgency, and regulation superfactors to early childhood feeding, eating, and weight outcomes.

METHODS

PubMed, PsycINFO and Embase databases, as well as scientific meeting programs, were searched using keywords and subject headings. Publication dates were limited to 2012-2019 as prior reviews were published in 2012 and 2014. Identified studies were eligible if they included children ages 0-5 years, a measure of child temperament, and a measure of parent/caregiver feeding, child eating, or child weight. 7113 studies were identified and 121 met inclusion criteria.

RESULTS

Feeding, eating, and weight outcomes were largely unrelated to overarching negative reactivity, surgency, and effortful control superfactors. Examination of individual temperament dimensions suggested difficult temperament was frequently linked to non-responsive feeding practices, whereas elevated emotionality and decreased self-regulation were linked to maladaptive eating behaviors, and lower inhibitory control to adiposity. Analyses with infants reported greater percentages of significant associations compared to children, and cross-sectional studies generally reported fewer significant associations than other study designs.

CONCLUSIONS

Difficult temperament, greater emotionality and lower self-regulation and inhibitory control were the aspects of temperament most consistently related to poorer early childhood feeding, eating, and weight outcomes. Associations tended to be stronger in infancy, and when examined within a non-cross-sectional study design. Findings can inform the development of tailored efforts to promote healthy eating and growth throughout childhood.

Effortful control and health among triads of mothers and twin children: An actor-partner interdependence modeling approach

Associations between effortful control and physical and mental health were examined among triads of mothers and twin children by simultaneously modeling the effects of one's own effortful control on one's own health (actor effects) with the effects of the other two family members' effortful control on one's health (partner effects). Families (N = 761 individuals; 254 families) included mothers (M_age = 39.98, SD = 5.64) and their twin children (M_age = 8.58, SD = 0.57; 51% female; 54.7% non-Hispanic White, 28% Hispanic). Mothers completed online and in-person questionnaires, and mothers' and children's body composition indicators and dominant-handgrip strength were directly assessed during two home visits. Actor effects dominated in families with twin boys and mixed-sex twins, whereas partner effects were more apparent in families with twin girls. In addition, the effects of children's effortful control on mothers' health depended on the sex of the twins. Findings uncovered important family dynamics linking effortful control to health, including that associations may vary by sex match of children in the family.

Temperament and eating self-regulation in young children with or at risk for obesity: An exploratory report

BACKGROUND

Few studies have examined the relationship between temperament and eating self-regulation in early childhood, despite emerging evidence for associations with pediatric obesity.

METHOD

The aim of this exploratory report was to examine the associations between three eating behaviors and three facets of temperament among 4- to 8-year-olds with or at risk for obesity.

RESULTS

Among 28 participants in a family intervention to reduce eating speed, we found at baseline that slower child eating speed was associated with less surgency (r = -.39, p = .04) and higher food responsiveness was associated with higher negative affect (r = .40, p = .03).

CONCLUSIONS

These findings support the potential yield of integrating temperament with eating self-regulation assessments in studies of early obesity risk. A better understanding is needed regarding ways in which parents differentially feed in response to child temperament.

Tantrums, toddlers and technology: Temperament, media emotion regulation, and problematic media use in early childhood

Parents regularly use media to help regulate their child's difficult emotions, particularly for those with a more difficult temperament. However, no research has examined how this may be related to the development of problematic (or addictive-like) media use in early childhood. The purpose of the study was to examine associations between temperament, parental media emotion regulation, and problematic media use in young children, using both questionnaires and observational data. Participants included 269 toddlers (2-3 years old) and their parents, who completed several observational tasks and questionnaires. Analyses revealed that higher levels of media emotion regulation was associated with more problematic media use and more extreme emotions when media was removed in toddlers. Additionally, temperament (specifically negative affect and surgency) was related to problematic media and extreme emotions and was mediated by media emotion regulation. Parents should avoid using media as a primary way of regulating their children's emotions as this may be related to the development of problematic media strategies during infancy.

Associations among Toddlers’ and Preschoolers’ Sleep Problems, Emotional Reactivity, Sleep Regime and Parental Applied Rules for Screen-Based Media Use

Background. Children’s sleep problems are associated with temperament. One of the dimensions of temperament – higher emotional reactivity – is defined as a risk factor for children’s emotional, behavioral, and sleep problems. Screen-based media use is a very common phenomenon among children that relates to sleep problems. Still there is a gap of research explaining the interactions between children’s sleep problems, temperament, and parental discipline (sleep regime and rules for screen-based media use). The aim of this study is to evaluate the relations between preschool children’s sleep problems and parents’ discipline (sleep regime and rules for screen-based media use), and the role of children’s emotional reactivity. Methods. This research is a part of the longitudinal study “Electronic Media Use and Young Children’s Health” conducted in the year 2017–2018 and funded by the Research Council of Lithuanian (agreement no. GER-006/2017). Participants are 876 children aged 2 to 5 years old and their parents. Children’s sleep problems and emotional reactivity were assessed using the Child Behavior Checklist (CBCL/1½-5). Information about rules for screen-based media use and sleep regime was obtained using the parent-report questionnaire. Results. Sleep problems are related to emotional reactivity, sleep regime, and rules for screen media use. Children without regular sleep regime and without constant rules for screen-based media use have higher sleep problems and emotional reactivity. The results of the regression analysis show that emotional reactivity, together with sleep regime and rules for screen-based media use, significantly explain one-fifth to one-third of children’s sleep problems at different ages of the preschool period. However, the prognostic value of emotional reactivity and parental discipline varies according to a child’s age, as they are significant predictors of sleep problems among two, three and four-year-olds, but no longer explain sleep problems of five-year-olds. The path analysis confirmed that emotional reactivity, directly and through mediating variables, e.g., parental reported child’s sleep regime and rules for screen-based media use, is significantly associated with children’s sleep problems. Conclusions. Emotional reactivity should be considered as a significant risk factor in the relation between children’s sleep problems, sleep regime and parental applied rules for screen-based media use. These results are important while identifying children at higher risk for sleep problems. The results also support that parental discipline, such as sleep regime and rules for screen-based media use, are significant for preventing sleep problems in children with higher emotional reactivity.

Temperament profiles are associated with dietary behavior from childhood to adulthood

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.

"Food" and "non-food" self-regulation in childhood: a review and reciprocal analysis

BACKGROUND

In developmental science, there is an extensive literature on non-food related self-regulation in childhood, where several domains relating to emotions, actions and cognitions have been identified. There is now growing attention to food related self-regulation in childhood, especially difficulties with ASR, and the consequences for weight gain and adiposity. The aim of this narrative review was to conduct a reciprocal analysis of self-regulation in the food and non-food domains in childhood (referred to as appetite self-regulation (ASR) and general self-regulation (GSR) respectively). The focus was on commonalities and differences in key concepts and underpinning processes.

METHODS

Databases and major journals were searched using terms such as self-regulation, appetite self-regulation, or self-regulation of energy intake, together with associated constructs (e.g., Executive Function, Effortful Control, delay-of-gratification). This was followed by backward and forward snowballing.

RESULTS AND DISCUSSION

The scholarship on GSR in childhood has had a focus on the role of the cognitively-oriented Executive Function (EF), the temperamentally-based Effortful Control (EC) and the recursive interplay between bottom-up (reactive, emotion driven, approach or avoidance) and top-down (cognitive, conscious decision-making) processes. "Hot" and "cool/cold" EF and self-regulation situations have been distinguished. There were some parallels between GSR and ASR in these areas, but uncertainty about the contribution of EF and EC to ASR in young children. Possible differences between the contribution to ASR-related outcomes of delay-of-gratification in food and non-food tasks were apparent. Unique elements of ASR were identified; associated with psychological, biological and neurological responses to food and bottom-up processes. A diverse number of situations or elements connected to ASR exist: for example, energy balance homeostasis, caloric compensation, hunger regulation, satiation, satiety, energy density of food, eating in the absence of hunger, emotional eating, etc. CONCLUSIONS: Self-regulation in food and non-food domains are amenable to a reciprocal analysis. We argue that self-regulation of appetite should be added as a domain under the umbrella of self-regulation in childhood along with the other non-food related domains. This could lead to a broader understanding of self-regulation in childhood, and generate novel lines of enquiry.

Child Temperament, Maternal Feeding Practices, and Parenting Styles and Their Influence on Obesogenic Behaviors in Hispanic Preschool Children

Although obesogenic behaviors (physical activity and/or sedentary behavior and dietary intake) are known predictors of childhood weight status, little is known about mother and child behaviors contributing to obesogenic behaviors and obesity in Hispanic preschool children, whose obesity rate is higher than in non-Hispanic Whites and non-Hispanic Blacks. The purpose of this cross-sectional, descriptive study was to examine relationships among child temperament, maternal behaviors (feeding practices and parenting style), child obesogenic behaviors, and child weight status in 100 Hispanic preschool children. Results showed that higher scores on the negative affectivity dimension of child temperament were associated with higher scores on the dimension of permissive parenting, and permissive parenting was associated with less time spent in sedentary behaviors (B = -3.53, confidence interval [-7.52, -0.90]). Findings can guide school nurses in developing interventions that consider child temperament and parenting style to promote nonobesogenic behavior in Hispanic preschoolers.
