Infant temperament: implications for later sleep and eating/feeding

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.

Relations between bedtime parenting behaviors and temperament across 14 cultures

Objectives

The present study examined parental sleep-supporting practices during toddlerhood in relation to temperament across 14 cultures. We hypothesized that passive sleep-supporting techniques (e.g., talking, cuddling), but not active techniques (e.g., walking, doing an activity together), would be associated with less challenging temperament profiles: higher Surgency (SUR) and Effortful Control (EC) and lower Negative Emotionality (NE), with fine-grained dimensions exhibiting relationships consistent with their overarching factors (e.g., parallel passive sleep-supporting approach effects for dimensions of NE).

Methods

Caregivers (N = 841) across 14 cultures (M = 61 families per site) reported toddler (between 17 and 40 months of age; 52% male) temperament and sleep-supporting activities. Utilizing linear multilevel regression models and group-mean centering procedures, we assessed the role of between- and within-cultural variance in sleep-supporting practices in relation to temperament.

Results

Both within-and between-culture differences in passive sleep-supporting techniques were associated with temperament attributes, (e.g., lower NE at the between-culture level; higher within-culture EC). For active techniques only within-culture effects were significant (e.g., demonstrating a positive association with NE). Adding sleep-supporting behaviors to the regression models accounted for significantly more between-culture temperament variance than child age and gender alone.

Conclusion

Hypotheses were largely supported. Findings suggest parental sleep practices could be potential targets for interventions to mitigate risk posed by challenging temperament profiles (e.g., reducing active techniques that are associated with greater distress proneness and NE).

Emotional Over- and Undereating in Children: A Longitudinal Analysis of Child and Contextual Predictors

Eating more or eating less in response to negative emotions, called emotional over- and undereating, is common in children, but research on the etiology of these behaviors is in its infancy. Drawing on a large, representative community sample of Norwegian children followed up on a biennial basis from 6 to 10 years of age (analysis sample: n = 802), child and contextual predictors (i.e., child temperament, depression symptoms, serious life events, family functioning, parental sensitivity and structuring) of change in emotional over- and undereating were examined. Results revealed that low (temperamental) soothability and less parental structuring at age 6 predicted increased emotional overeating at age 10 and that lower family functioning at age 6 predicted more emotional undereating during the same period.

Infant, maternal, and familial predictors and correlates of regulatory problems in early infancy: The differential role of infant temperament and maternal anxiety and depression

BACKGROUND

Excessive infant crying, feeding and sleeping problems are likely to emerge from the complex interplay of various factors.

AIMS

To investigate the role of infant (e.g., temperament), maternal (e.g., anxiety and depressive disorders), and familial (e.g., social support) factors as potential precursors of infant regulatory problems.

STUDY DESIGN

Prospective-longitudinal study.

SUBJECTS

286 mother-infant dyads were investigated from early pregnancy until 16 months postpartum via questionnaires and interviews.

OUTCOME MEASURES

Regulatory problems at 2, 4 and 16 months postpartum assessed by standardized diagnostic interviews.

RESULTS

Fussy infant temperament and maternal anxiety disorders were associated with excessive infant crying (OR=1.16, 95%CI:1.05-1.29, OR=3.28, 95%CI:1.16-9.26) and feeding problems (OR=1.05, 95%CI:1.01-1.11, OR=2.27, 95%CI:1.36-3.80) whereas maternal depressive disorders were associated with infant sleeping problems (OR=2.55, 95%CI:1.06-6.11). Moreover, high maternal age (OR=0.86, 95%CI:0.75-0.98) was associated with a lower risk for excessive crying and being a single mother (OR=0.16, 95%CI:0.03-0.73) and cognitive reappraisal to regulate emotions (OR: 0.59, 95%CI:0.36-0.96) was associated with a lower risk for sleeping problems.

CONCLUSION

Excessive infant crying and feeding problems may be related to interactional deficits of anxious mothers who perceive their infants as "difficult" during soothing or feeding situations. Sleeping problems may be transmitted already during pregnancy by an altered sleep-wake-rhythm of mothers with a history of depression or by a genetic predisposition. Therapeutic interventions should focus on maternal anxiety and depression, behavior management techniques to cope with difficult situations with "fussy" infants and potential protective factors (e.g. favorable maternal emotion regulation) to address crying, feeding and sleeping problems.

Weight Status as a Mediator of the Association Between Preschool Extraversion and Adolescent Restrained Eating

Objectives

To determine the longitudinal association between preschool extraversion and weight/dieting outcomes in adolescence.

Methods

Children (N = 180) were recruited as part of a longitudinal study, with child temperament assessed in preschool (age 5.25 years), weight assessed in 2nd grade and early adolescence, and eating outcomes assessed in early adolescence (mean age = 12.02 years).

Results

Preschoolers high in extraversion were significantly more likely to have higher body mass index z-scores (zBMI) and more restrained eating behaviors in adolescence. zBMI was found to mediate the relationship between extraversion and restrained eating, such that children with high levels of extraversion were more likely to have higher zBMI in adolescence and, owing to this higher weight status, to engage in more restrained eating.

Conclusions

Temperament is an important predictor of later maladaptive weight/dieting outcomes in adolescence, making it a potentially important early factor to consider in weight management interventions.

Associations between infant temperament, maternal stress, and infants' sleep across the first year of life

Effects of temperament and maternal stress on infant sleep behaviors were explored longitudinally. Negative temperament was associated with sleep problems, and with longer sleep latency and night wakefulness, whereas maternal stress was associated with day sleep duration, suggesting infant and maternal characteristics affect sleep differentially.
