Project description:Weight status and rate of weight gain in the first six months postpartum are strong predictors of later obesity; thus, infant feeding practices are an important target for obesity prevention efforts. The use of food to soothe (FTS) is associated with less-favorable eating habits and weight outcomes for older infants and children. However, few studies have examined correlates of use of FTS during early infancy. The primary aim of this cross-sectional study was to explore associations between use of FTS and infant weight status in the first 6 months postpartum. A secondary aim was to identify the combination of maternal and infant characteristics that predicted use of FTS. Mothers of infants aged 6 months or younger (N = 134) completed questionnaires assessing use of FTS, bottle-feeding intensity (i.e., percentage of daily feedings from bottles versus directly from the breast), levels of responsive and pressuring feeding styles, dimensions of infant temperament and eating behaviors, and family demographics. Dyads were observed during feeding to assess maternal sensitivity to infant cues and responsiveness to infant distress and infant clarity of cues and responsiveness to the mother. Infant weight and length at study entry were assessed by a trained research assistant. Use of FTS was not associated with infant weight for age z-score (WAZ), even when bottle-feeding intensity was considered as a moderator. More frequent use of FTS was predicted by the combination of greater levels of pressuring feeding style (p = .005) and infant temperamental negative affectivity (p = .001), and lower levels of infant temperamental surgency/extraversion (p = .018). In conclusion, use of FTS was associated with dimensions of infant temperament and maternal feeding style, but not with WAZ during early infancy.

Project description:ImportanceInfant temperament is associated with excess weight gain or childhood obesity risk in samples of healthy individuals, although the evidence has been inconsistent. To our knowledge, no prior research has examined this topic among children exposed to gestational diabetes mellitus (GDM) in utero.ObjectiveTo prospectively evaluate infant temperament in association with overweight and obesity status at ages 2 to 5 years among children born to mothers who experienced GDM.Design, setting, and participantsThis prospective cohort study took place at Kaiser Permanente Northern California medical centers. We studied singleton infants delivered at 35 weeks' gestational age or later to mothers who had been diagnosed with GDM. Data were collected from 2009 to 2016, and data analysis occurred from June 2017 to October 2018.ExposuresThe primary exposures in the child's first year were soothability, distress to limitations, and activity aspects of temperament, as assessed by a validated questionnaire. Modifiable covariates in the child's first year included breastfeeding intensity and duration monthly ratio scores, along with the timing of the introduction of sugary beverages and complementary foods.Main outcomes and measuresThe primary outcome was child overweight and obesity status, assessed at ages 2 to 5 years. Multinomial logistic regression models estimated adjusted odds ratios and 95% CIs for infants whose temperaments were measured at 6 to 9 weeks of age and categorized as elevated (≥75th percentile) or not elevated in the 3 domains. We controlled for nonmodifiable and modifiable covariates across models.ResultsA total of 382 mother-infant pairs participted, including 130 infants (34.0%) who were non-Hispanic white, 126 infants (33.0%) who were Hispanic, 96 infants (25.1%) who were Asian, 26 infants (6.8%) who were non-Hispanic black, and 4 infants (1.1%) who were of other races/ethnicities. In descriptive analyses, elevated infant soothability and activity temperaments were associated with the early introduction of 100% fruit juice and/or sugar-sweetened beverages (at ages <6 months) and shorter breastfeeding duration (from 0 to <3 months), while elevated distress to limitations was associated with early introduction of complementary foods (at ages <4 months). Elevated soothability consistently was associated with a higher odds of later childhood obesity, with adjusted odds ratios across models ranging from 2.22 (95% CI, 1.04-4.73) to 2.54 (95% CI, 1.28-5.03). Greater breastfeeding intensity and duration (12-month combined) score was associated with lower odds of obesity, independent of infant temperament and other covariates.Conclusions and relevanceAmong this high-risk population of infants, elevated soothability was associated with early childhood obesity risk, perhaps in part because caregivers use sugary drinks to assuage infants. Soothability temperament may be a novel screening target for early obesity prevention interventions involving responsive feeding and emotion regulation.

Project description:Parental feeding practices, such as the use of food to soothe, can be shaped by various factors, including the family environment and parents' psychological characteristics and capacities. To our knowledge, the combined effect of these factors has not been studied. Furthermore, parental feeding practices have mainly been studied in women, resulting in a gender gap in the research. This study aims to investigate the combined effect of family environment and parental characteristics on the likelihood of using food to soothe children, taking the gender of both parents into account. This cross-sectional study included a sample of 846 parents (36.3% men) of 1-year-old children from different regions of Spain. Participants completed an online survey that included questionnaires to measure whether parents used food to soothe children, the family environment, parents' characteristics, and their psychological capacities. Binary logistic regression analyses were performed to identify associations between the variables. The final model showed that, within the family environment, higher levels of dyadic adjustment between couples (OR = 0.965; p = .026) were associated with a reduced likelihood of using food to soothe children, whereas the psychological characteristic of parental fatigue (OR = 1.053; p = .007) appeared to be associated with an increased likelihood. Also associated with an increased likelihood of this practice were higher parental sense of competence (OR = 1.028; p = .029) and the attention dimension of emotional intelligence (OR = 1.043; p = .007). Our study suggests that using food to soothe children may be influenced by factors at different levels, from the quality and adjustment of the couple's relationship to parental fatigue, self-competence, and emotional intelligence. For future research, it may be worthwhile contextualizing parental practices to gain a better understanding of children's behavior.

Project description:In this functional magnetic resonance imaging (fMRI) study we examined neural processing of infant faces associated with a happy or a sad temperament in nulliparous women. We experimentally manipulated adult perception of infant temperament in a probabilistic learning task. In this task, participants learned about an infant's temperament through repeated pairing of the infant face with positive or negative facial expressions and vocalizations. At the end of the task, participants were able to differentiate between "mostly sad" infants who cried often and "mostly happy" infants who laughed often. Afterwards, brain responses to neutral faces of infants with a happy or a sad temperament were measured with fMRI and compared to brain responses to neutral infants with no temperament association. Our findings show that a brief experimental manipulation of temperament can change brain responses to infant signals. We found increased amygdala connectivity with frontal regions and the visual cortex, including the occipital fusiform gyrus, during the perception of infants with a happy temperament. In addition, amygdala connectivity was positively related to the post-manipulation ratings of infant temperament, indicating that amygdala connectivity is involved in the encoding of the rewarding value of an infant with a happy temperament.

Project description:Background: Most observational research examining factors in the home environment that contribute to child adiposity has focused on feeding and physical activity, although aspects of one's nonfood home environment such as parent-child interactions can also impact body weight. The main objectives of this study were to determine if parent-infant interactions under different contexts provide a unique contribution to infants' concurrent adiposity after accounting for known obesity-related covariates. Methods: This was a cross-sectional analysis of 121 9- to 15-month-old infants using data collected at the baseline visit of an ongoing intervention study. Mother-infant interactions during a feeding episode and a free-play task were recorded and coded. Anthropometrics of infants were measured by trained research staff. We used two-step hierarchical multivariable regression models to examine the unique contribution of mother-infant interactions to weight status after accounting for known obesity-related covariates (i.e., maternal age, BMI, education, parity, and gestational age, child sex, breastfeeding duration, age of solid food introduction, and birthweight). Results: Maternal intrusiveness, child negative affect, and child responsiveness during free-play, but not feeding were significantly associated with z-weight-for-length. For every 1-U increase in maternal intrusiveness and child negative affect there was a 0.321 (p = 0.011) and 0.415 (p = 0.028) unit increase in z-weight-for-length, respectively, whereas for every 1-U increase in child responsiveness there was a decrease of 0.386 U in z-weight-for-length (p = 0.025). Conclusion: This research contributes new findings support the idea that parent-child interactions outside of the feeding context may relate to obesity.

Project description:BACKGROUND & METHODS:To examine the relationship between breastfeeding and maternally-rated infant temperament at age 3 months, 316 infants in the prospective Cambridge Baby Growth Study, UK had infant temperament assessed at age 3 months by mothers using the Revised Infant Behavior Questionnaire, which produces scores for three main dimensions of temperament derived from 14 subscales. Infant temperament scores were related to mode of infant milk feeding at age 3 months (breast only; formula milk only; or mixed) with adjustment for infant's age at assessment and an index of deprivation. RESULTS:Infant temperament dimension scores differed across the three infant feeding groups, but appeared to be comparable between exclusive breast-fed and mixed-fed infants. Compared to formula milk-fed infants, exclusive breast-fed and mixed-fed infants were rated as having lower impulsivity and positive responses to stimulation (adjusted mean [95% CI] "Surgency/Extraversion" in formula-fed vs. mixed-fed vs. breast-fed groups: 4.3 [4.2-4.5] vs. 4.0 [3.8-4.1] vs. 4.0 [3.9-4.1]; p-heterogeneity?=?0.0006), lower ability to regulate their own emotions ("Orienting/Regulation": 5.1 [5.0-5.2], vs. 4.9 [4.8-5.1] vs. 4.9 [4.8-5.0]; p?=?0.01), and higher emotional instability ("Negative affectivity": 2.8 [2.6-2.9] vs. 3.0 [2.8-3.1] vs. 3.0 [2.9-3.1]; p?=?0.03). CONCLUSIONS:Breast and mixed-fed infants were rated by their mothers as having more challenging temperaments in all three dimensions; particular subscales included greater distress, less smiling, laughing, and vocalisation, and lower soothability. Increased awareness of the behavioural dynamics of breastfeeding, a better expectation of normal infant temperament and support to cope with difficult infant temperament could potentially help to promote successful breastfeeding.

Project description:Maternal biological systems impact infant temperament as early as the prenatal period, though the mechanisms of this association are unknown. Using a prospective, longitudinal design, we found that maternal (N = 89) amplitudes of the late positive potential (LPP) in response to negative stimuli during the second, but not the third, trimester of pregnancy predicted observed and physiological indices of temperamental reactivity in infants at age 4 months. Maternal LPP was positively associated with observed infant fear and negatively associated with frontal EEG asymmetry and cortisol reactivity in infants at age 4 months. Results identify a putative mechanism, early in pregnancy, for the intergenerational transmission of emotional reactivity from mother to infant.

Project description:Recent models of psychopathology suggest the presence of a general factor capturing the shared variance among all symptoms along with specific psychopathology factors (e.g., internalizing and externalizing). However, few studies have examined predictors that may serve as transdiagnostic risk factors for general psychopathology from early development. In the current study we examine, for the first time, whether observed and parent-reported infant temperament dimensions prospectively predict general psychopathology as well as specific psychopathology dimensions (e.g., internalizing and externalizing) across childhood. In a longitudinal cohort (N = 291), temperament dimensions were assessed at 4 months of age. Psychopathology symptoms were assessed at 7, 9, and 12 years of age. A bifactor model was used to estimate general, internalizing, and externalizing psychopathology factors. Across behavioral observations and parent-reports, higher motor activity in infancy significantly predicted greater general psychopathology in mid to late childhood. Moreover, low positive affect was predictive of the internalizing-specific factor. Other temperament dimensions were not related with any of the psychopathology factors after accounting for the general psychopathology factor. The results of this study suggest that infant motor activity may act as an early indicator of transdiagnostic risk. Our findings inform the etiology of general psychopathology and have implications for the early identification for children at risk for psychopathology.

Project description:BACKGROUND:Conditioned eating in response to external food cues may contribute to obesity risk in young children. OBJECTIVES:To develop a brief, parent-reported scale to measure external food cue responsiveness for preschool-age children. METHODS:Focus groups with parents of preschool-age children were conducted to create an initial pool of items reflecting children's behavioral responses to external food cues. Items were included in a nationally-distributed online survey of parents of preschool-age children (n?=?456). Factor analysis was used to reduce the initial item pool, the scale's psychometric properties were assessed, and scores were correlated with reported snacking behaviors. RESULTS:Nine items met inclusion criteria in the final scale, which had high internal consistency (alpha?=?0.86). Final scores were the mean across the nine items. External food cue responsiveness was greater among children with, versus without, usual TV advertisement exposure. Furthermore, greater external food cue responsiveness mediated the relationship between children's usual TV advertisement exposure and snacking during TV viewing. Findings remained statistically significant when adjusted for food responsiveness as measured with the Child Eating Behavior Questionnaire. CONCLUSIONS:Findings provide preliminary evidence that external food cue responsiveness is measurable by parental report in preschool-age children.

Project description:BackgroundUse of food to soothe infant distress has been linked to greater weight in observational studies. We used ecological momentary assessment to capture detailed patterns of food to soothe and evaluate if a responsive parenting intervention reduced parents' use of food to soothe.MethodsPrimiparous mother-newborn dyads were randomized to a responsive parenting intervention designed for obesity prevention or a safety control group. Responsive parenting curriculum included guidance on using alternative soothing strategies (e.g., swaddling), rather than feeding, as the first response to infant fussiness. After the initial intervention visit 3 weeks after delivery, mothers (n = 157) were surveyed for two 5-8 day bursts at infant ages 3 and 8 weeks. Surveys were sent via text message every 4 h between 10:00 AM-10:00 PM, with 2 surveys sent at 8:00 AM asking about nighttime hours. Infant fusses and feeds were reported for each 4-h interval. Food to soothe was defined as "Fed First" and "Not Fed First" in response to a fussy event. Use of food to soothe was modeled using random-intercept logistic regression.ResultsThe control group had greater odds of having Fed First, compared to the responsive parenting group at ages 3 and 8 weeks (3 weeks: OR = 1.9; 95% CI = 1.4-2.7; p < 0.01; 8 weeks: OR = 1.4; 95% CI = 1.0-2.1; p = 0.053). More responsive parenting mothers reported using a responsive parenting intervention strategy first, before feeding, than controls at ages 3 and 8 weeks (3 weeks: 58.1% vs. 41.9%; 8 weeks: 57.1% vs. 42.9%, respectively; p < 0.01 for both). At both ages combined, fewer fusses from responsive parenting infants were soothed best by feeding compared to controls (49.5% vs. 61.0%, respectively; p < 0.01). For both study groups combined, parents had greater odds of having Fed First during the nighttime compared to the daytime at both ages (3 weeks: OR = 1.6, 95% CI = 1.4-1.8; p < 0.01; 8 weeks: OR = 2.1; 95% CI = 1.7-2.6; p < 0.01).ConclusionsINSIGHT's responsive parenting intervention reduced use of food to soothe and increased use of alternative soothing strategies in response to infant fussiness. Education on responsive parenting behaviors around fussing and feeding during early infancy has the potential to improve later self-regulation and weight gain trajectory.Trial registrationNCT01167270 .
