Early-life family meal participation has been associated with several aspects of nutritional health, but longitudinal associations with linear growth have not yet been investigated. The aim of this study was to investigate whether family meal participation at 12 months of age associates with anthropometric measures 3 years later. We used follow-up data from children born to mothers in the Norwegian Fit for Delivery trial (NFFD) and included 368 first-borns with dietary and anthropometric data at 12 months and 4 years of age. We treated the sample as a cohort and conducted subgroup analyses by randomization status. A family meal participation score was used as exposure, and weight, height, and body mass index (BMI) as outcomes in crude and multivariable linear regression models adjusted for maternal education, randomization status, and child sex.Higher family meal participation score at 12 months was positively associated with length at 12 months (B = 0.198, 95% CI 0.028, 0.367, p = 0.022) and 4 years (B = 0.283, 95% CI 0.011, 0.555, p = 0.042) in multivariable models. After additional adjustment for maternal height the associations attenuated and were no longer significant. An inverse association with BMI at 4 years of age was observed in children born to mothers that had been exposed to the NFFD intervention (B = -0.144, 95% CI -0.275, -0.014, p = 0.030), but attenuated after adjustment for maternal BMI.The longitudinal association observed between early family meal participation and child height was largely explained by maternal height. The relationship with BMI differed according to maternal participation in a lifestyle intervention trial during pregnancy.

Parent-child dysfunctional interactions (PCDI) are known to contribute to children\'s weight status. However, the underlying mechanisms in how dysfunctional interactions between parent and child influence child weight are not clear. This study investigates the impact of PCDI on toddlers\' weight, focusing on the potential serial mediation by maternal emotional feeding and child appetite traits. We conducted a secondary analysis of longitudinal data from a larger intervention trial to prevent childhood obesity in low-income Hispanic families. A total of 241 mother-child dyads were included in these analyses. Measurements were taken at various stages: PCDI at child age 19 months, maternal emotional feeding at 28 months, and both child appetite traits and weight-for-age z-score (WFAz) at 36 months. Serial mediation analyses revealed a significant indirect effect of early PCDI on later child WFAz through maternal emotional feeding and two child food approach traits (food responsiveness, emotional overeating) out of the eight child appetite traits assessed. PCDI at 19 months was associated with increased use of emotional feeding in mothers at 28 months, which was associated with heightened food responsiveness and emotional overeating in children at 36 months, which in turn was linked to greater child WFAz at 36 months. The findings of this study expand the understanding of the mechanisms underlying PCDI and child weight, emphasizing the interplay between maternal feeding practices and child appetite in the context of adverse parent-child interactions during early childhood.

BACKGROUND: Early entry into nonparental care (NPC) and introduction to solid foods (ITS) have been linked to elevated weight, however, little research exists on the combined influence of these transitions on child weight over time.
OBJECTIVE: Identify groups of children based on early NPC and ITS timing and examine whether NPC-ITS groups differentially affect child weight over time.
METHODS: Data were drawn from STRONG Kids2 (n = 468). Primary predictors include NPC (by 3M)-ITS (< or ≥6M) groups; outcome variables include child weight-for-length/height z-scores (WFL/WFHz) (3, 12, 18, and 24 months). Multilevel regression was used to examine the NPC-ITS groups as predictors of child WFL/WFHz.
RESULTS: Six groups were identified: 27% Parental Care-ITS before 6M, 31% Parental Care-ITS after 6M, 12% Daycare-ITS before 6M, 14% Daycare-ITS after 6M, 10% Kincare-ITS before 6M, and 7% Kincare-ITS after 6M. Children who were in daycare (regardless of ITS) or kincare-ITS before 6M demonstrated the highest WFL/WFHz over time, compared to their parental care counterparts.
CONCLUSIONS: NPC-ITS combinations on child WFL/WFHz across the first 2 years of life highlight the need for a partnership approach among parental and nonparental caregivers to support the feeding of infants throughout the transition to solid foods.

The purpose of this study is to examine associations between maternal lipid profiles in pregnancy and offspring growth trajectories in a largely macrosomic cohort. This is a secondary analysis of the ROLO birth cohort (n = 293), which took place in the National Maternity Hospital, Dublin, Ireland. Infants were mostly macrosomic, with 55% having a birthweight > 4 kg. Maternal mean age was 32.4 years (SD 3.9 years), mean BMI was 26.1 kg/m2 (SD 4.4 kg/m2) and 48% of children born were males. Total cholesterol, high density lipoprotein cholesterol (HDL-cholesterol), low density lipoprotein cholesterol (LDL-cholesterol) and triglycerides were measured from fasting blood samples of mothers at 14 and 28 week gestation. The change in maternal lipid levels from early to late pregnancy was also examined. Offspring abdominal circumference and weight were measured at 20- and 34-week gestation, birth, 6 months, 2 years and 5 years postnatal. Linear spline multilevel models examined associations between maternal blood lipid profiles and offspring growth. We found some weak, significant associations between maternal blood lipids and trajectories of offspring growth. Significant findings were close to the null, providing limited evidence. For instance, 1 mmol/L increase in maternal triglycerides was associated with faster infant weight growth from 20- to 34-week gestation (0.01 kg/week, 95% CI - 0.02, - 0.001) and slower abdominal circumference from 2 to 5 years (0.01 cm/week, 95% CI - 0.02, - 0.001). These findings do not provide evidence of a clinically meaningful effect.    Conclusion: These findings raise questions about the efficacy of interventions targeting maternal blood lipid profiles in pregnancies at risk of macrosomia. New studies on this topic are needed. What is Known: • Maternal fat accumulation during early pregnancy may potentially support fetal growth in the third trimester by providing a reserve of lipids that are broken down and transferred to the infant across the placental barrier. • There are limited studies exploring the impact of maternal lipid profiles on infant and child health using growth trajectories spanning prenatal to postnatal life. What is New: • Maternal blood lipid profiles were not associated with offspring growth trajectories of weight and abdominal circumference during pregnancy up to 5 years of age in a largely macrosomic cohort, as significant findings were close to the null, providing limited evidence for a clinically meaningful relationship. • Strengths of this work include the use of infant growth trajectories that span prenatal to postnatal life and inclusion of analyses of the change of maternal lipid levels from early to late pregnancy and their associations with offspring growth trajectories from 20-week gestation to 5 years of age.

Many parents express concern about the impact of talking to children about weight on their self-esteem and wellbeing. The aim of this study was to explore the perceived relevance, utility and acceptability of new guidance for parents on talking to children about weight, developed to apply theory, evidence and expert advice into practice.
For this qualitative study, parents and public health practitioners (PHPs) were recruited from ten local authorities in England, through the National Child Measurement Programme between June and September 2021. Participants were sent a copy of the guidance document and took part in an interview approximately one week later. Interviews were transcribed verbatim and explored using thematic analysis.
12 parents and 15 PHPs took part, and were similar in their responses reporting the guidance to be acceptable, relevant and helpful. Theme 1 explored how the guidance reduced perceptions of stigma and blame through the perspective and tone that was adopted. Theme 2 explored how the guidance could provide reassurance and increase confidence as a result of case study examples, and specific tips and advice. Theme 3 explored the extent to which participants perceived the advice to be realistic and how it could fit with existing PHP practice. Suggestions for improvement included adapting for relevance for lower income families and providing separate advice for parents of older and younger children.
The guidance was perceived as relevant and needed; it showed potential to reduce parents\' negative affect and concerns, and improve confidence around talking to children about weight.

BACKGROUND: Early childhood is a pivotal period for the development of healthy eating practices. One way to promote child health is to identify early modifiable factors that affect child eating and weight. Given the intergenerational transmission of eating behaviors, this study examined how mothers\' eating behaviors were associated with child feeding practices, and whether child weight-for-length (z-WFL) moderated this relation, in a community sample.
METHODS: Participants were 72 mother-child dyads. Maternal eating behaviors-emotional, external and restrained-were assessed 9-months postpartum, using the Dutch Eating Behavior Questionnaire. Child feeding-restrictive, pressure, and concern about overeating/overweight or undereating/underweight-was measured using the Infant Feeding Questionnaire, and child z-WFL were assessed 18-months postpartum. Linear regressions were used to test the main effect of maternal eating and the interaction effect of maternal eating and child z-WFL, on child feeding practices.
RESULTS: Maternal restrained eating was associated with child pressure feeding, and contrarily with concerns about overeating/overweight. However, a significant interaction between child z-WFL and both maternal emotional and external eating were found with regard to concern about child undereating/underweight. Paradoxically, among children who weighed more, greater maternal emotional and greater external eating were associated with greater concern about child undereating/underweight.
CONCLUSIONS: In this community sample, mothers were more likely to report contradictory feeding practices and concerns, suggesting complicated relations among a mother\'s own eating behavior, her child\'s weight, and her perceptions of child eating and weight. This may indicate a need for better communication and support of infant feeding practices.
BACKGROUND: Data was collected as part of two grants (MAMAS Grant ID: HL097973-01; SEED Grant ID: HL116511-02) conducted at the University of California, San Francisco (UCSF). All subjects gave their informed consent for inclusion before they participated in the study. The study was conducted in accordance with the Declaration of Helsinki, and the protocol was approved by institutional review board at UCSF.

Child overweight remains a prevalent public health concern, but the impact of maternal psychosocial stress and related constructs, the timing, and possible trajectories on child body mass index (BMI) is controversial. We aimed to investigate the association of maternal stress, depression and anxiety symptoms, and maternal hair cortisol concentrations (HCC) at delivery, 6, and 12 months postpartum with child BMI and age- and sex-standardized BMI (BMI-SDS) at age 3 years.
Data were derived from the Ulm SPATZ Health Study with a baseline examination between 04/2012 and 05/2013 at the University Medical Centre Ulm, Germany, the only maternity clinic in Ulm, with a good representation of the source population. Adjusted regression analyses based on BMI/BMI-SDS (dependent) and trajectories of stress, depression, and anxiety (independent variables) were investigated in 596 mothers and children. Multiple imputation of missing covariates was performed.
Various trajectories in independent variables were identified, trajectories of maternal anxiety symptom differed between child sexes. We did not find an association between trajectories of maternal chronic stress, depression symptoms, or HCC and child BMI/BMI-SDS. However, trajectories of low-increasing maternal anxiety symptoms were linked to higher child BMI compared to a low-stable trajectory group (b = 0.58 kg/m2, 95% Confidence Interval: 0.11; 1.04) in girls.
Trajectories of maternal anxiety symptoms were associated with the child\'s BMI/BMI-SDS in girls at age 3 years. However, further large scale studies should include variables to determine the causal pathway and enlighten sex-specific differences.

Prevailing weight-normative approaches to health pressure adults to visually categorise children\'s weight, despite little understanding of how such judgements are made. There is no evidence this strategy improves child health, and it may harm children with higher weights. To understand decision-making processes and identify potential mechanisms of harm we examined perceptual and attitudinal factors involved in adults\' child weight category judgements. Eye movements of 42 adults were tracked while categorizing the weight of 40 computer-generated images of children (aged 4-5 & 10-11 years) varying in size. Questionnaires assessed child-focused weight bias and causal attributions for child weight. Participants\' eye movement patterns resembled those previously reported for adult bodies. Categorisation data showed a perceptual bias towards the \'mid-range\' category. For higher weight stimuli, participants whose category judgements most closely matched the stimulus\'s objective weight had higher child-focused anti-fat bias and weaker genetic attributions for child weight - i.e,. adults who \'label\' higher weight in children in line with BMI categories report more stigmatising beliefs about such children, suggesting a possible mechanism of harm. Overall, adults\' judgements reflect both unalterable perceptual biases and potentially harmful attitudinal factors, calling into question the feasibility and appropriateness of public health efforts to promote visual child weight categorisation.

UNASSIGNED: Psychosocial and physiologic stressors, such as depression and obesity, during pregnancy can have negative consequences, such as increased systemic inflammation, contributing to chronic disease for both mothers and their unborn children. These conditions disproportionately affect racial/ethnic minorities. The effects of recommended dietary patterns in mitigating the effects of these stressors remain understudied.
UNASSIGNED: We aimed to evaluate the relations between maternal Mediterranean diet adherence (MDA) and maternal and offspring outcomes during the first decade of life in African Americans, Hispanics, and Whites.
UNASSIGNED: This study included 929 mother-child dyads from the NEST (Newborn Epigenetics STudy), a prospective cohort study. FFQs were used to estimate MDA in pregnant women. Weight and height were measured in children between birth and age 8 y. Multivariable linear regression models were used to examine associations between maternal MDA, inflammatory cytokines, and pregnancy and postnatal outcomes.
UNASSIGNED: More than 55% of White women reported high MDA during the periconceptional period compared with 22% of Hispanic and 18% of African American women (P < 0.05). Higher MDA was associated with lower likelihood of depressive mood (β = -0.45; 95% CI: -0.90, -0.18; P = 0.02) and prepregnancy obesity (β = -0.29; 95% CI: -0.57, -0.0002; P = 0.05). Higher MDA was also associated with lower body size at birth, which was maintained to ages 3-5 and 6-8 y-this association was most apparent in White children (3-5 y: β = -2.9, P = 0.02; 6-8 y: β = -3.99, P = 0.01).
UNASSIGNED: If replicated in larger studies, our data suggest that MDA provides a potent avenue by which effects of prenatal stressors on maternal and fetal outcomes can be mitigated to reduce ethnic disparities in childhood obesity.

We examined the scope of literature including non-parental caregiver involvement in child obesity prevention interventions.
We conducted a scoping review following the Arksey and O\'Malley framework, including only studies reporting the effect of an intervention on growth, weight, or early childhood obesity risk among children ages 0 to three years, published between 2000 and 2021. Interventions that did not include non-parental caregivers (adults regularly involved in childcare other than parents) were excluded.
Of the 14 studies that met the inclusion criteria, all were published between 2013 and 2020, and most interventions (n = 9) were implemented in the United States. Eight of the 14 interventions purposefully included other non-parental caregivers: five included both parents and non-parental caregivers, and the remaining three included only non-parental caregivers. Most interventions (n = 9) showed no significant impact on anthropometric outcomes. All interventions found improvements in at least one behavioral outcome (e.g., food groups intake (n = 5), parental feeding practices (n = 3), and screen time (n = 2)). This review can inform future interventions that plan to involve non-parental caregivers, which may be beneficial in shaping early health behaviors and preventing obesity early in life.
