Reducing racial/ethnic disparities in childhood obesity: the role of early life risk factors

Beliefs and Perceptions of Physical Activity Among Black Adolescents in South Florida: A Qualitative Study

INTRODUCTION

In the United States, non-Hispanic Black adolescents have a significantly higher prevalence of obesity than their peers. Though physical activity (PA) has many benefits, many adolescents fail to engage in adequate amounts of PA. Black adolescents are also more sedentary than those from other races and ethnicities. This study aimed to describe the perceptions, beliefs, and barriers to PA in South Florida Black adolescents.

METHODS

Five focus groups were conducted with self-identified non-Hispanic Black adolescents (n = 38) in South Florida. A semi-structured question guide based on the Theory of Planned Behavior was used for group discussions. The open-ended questions addressed adolescents' (1) attitudes and beliefs toward PA, (2) current PA-related behaviors, and (3) environmental, social, cultural, and racial influences on health behaviors.

RESULTS

The desire to be healthy, thoughts of the future, and self-image were among the reasons participants engaged in PA. Engagement in PA was associated with a positive social environment, including encouragement from family and friends. Race, culture, and social media were also cited as influences on PA. Perceived control beliefs, such as parental pressures and self-discipline, also impacted PA.

CONCLUSION

Adolescents recognize the importance of PA; however, their behaviors do not reflect this. Barriers and motivators for Black adolescents are multifaceted. It is critical for Public Health practitioners and local legislators to understand the complexities to serve this population. This study's findings can guide the development of tailored PA and education programs for Black adolescent populations.

GLP-1 Receptor Agonists in Pediatric and Adolescent Obesity

Obesity remains highly prevalent among children in the United States and is associated with an ever-increasing burden of obesity-related diseases. Effective pediatric obesity prevention and treatment will require both societal interventions and health care system innovation. One recent advancement is the approval of glucagon-like peptide-1 receptor agonists (GLP-1RAs) for use in adolescents. GLP-1RAs are notable for their effectiveness in weight management and in their ability to ameliorate obesity-related diseases. GLP-1RAs can be an important part of a comprehensive treatment plan for pediatric patients seeking obesity care, and we will review the pediatric clinician's considerations for their effective use. We discuss the history of obesity pharmacology and development of GLP-1RAs. We review the indications for use and common adverse reactions. We highlight the importance of mental health care for obesity treatment, with a focus on disordered eating behaviors and their intersection with obesity and pharmacologic treatment of obesity. Nutrition remains an important issue for obesity prevention and management, and we highlight nutritional concerns during GLP-1RA therapy. Finally, we discuss health inequities in obesity, the dangers of perpetuating these inequities if GLP-1RA access remains biased, and the opportunities for improvement.

Barriers and Facilitators Influencing Parents' Willingness to Follow Healthcare Provider Guidance for Addressing Behaviors Linked to Early Childhood Obesity Risk: A Qualitative Descriptive Study

INTRODUCTION

This study aims to assess parents' willingness to modify behaviors associated with obesity risk upon a provider's recommendation in the first six months of life among non-Hispanic Black and Hispanic families.

METHOD

Twenty parents completed a survey about their current infant feeding, sleep, and nutritional behaviors that guided a tailored semistructured interview.

RESULTS

Barriers to parents' willingness to modify behaviors associated with obesity risk in infancy included prioritizing perception of infant hunger and relying on parental intuition. Facilitators included understanding the provider's reasoning and trusting the provider's motivations.

DISCUSSION

Health care providers are considered trusted sources by most parents and parents are willing to follow professional advice if providers share detailed explanations on the reasoning for behavior change recommendations. Future interventions created by trusted sources, like pediatric primary care providers, offer a promising mechanism for providing education on early life obesity prevention that is tailored to individual family needs.

Harnessing Mother's Strengths to THRIVE in Obesity Prevention Efforts: A Qualitative Study

Objectives

Infancy is a critical period for preventing obesity and health disparities. This study reports on the acceptability of a responsive parenting obesity prevention intervention (THRIVE) delivered via integrated behavioral health in a pediatric primary care setting. Intervention participants were invited to participate in a focus group on the acceptability of THRIVE and suggestions for refinement with particular attention to cultural responsiveness and diversity, equity, inclusion, and accessibility (DEIA).

Methods

Eleven of 32 (34.4%) mothers participated in a 45-60 minute focus group (three groups, 3-5 participants each). Sessions utilized a semi-structured interview guide, were transcribed verbatim, and analyzed according to a thematic analytic approach.

Results

Four themes emerged: (1) Lived Experience (e.g., lived experience as a mother, navigating systemic and healthcare-related barriers, and context that shaped personal experiences with THRIVE); (2) Therapeutic Processes and Cultural Responsiveness (e.g., an appreciation of families' strengths and values by the THRIVE interventionist that facilitated engagement with THRIVE); (3) Tailored Strategy Implementation (e.g., implementation of THRIVE skills and strategies by families and how strategies were adapted or tailored to meet families' needs); (4) Future Improvements to THRIVE (e.g., proposed strategies for increased attention to DEIA and reducing participant burden).

Conclusions

Conducting qualitative research prior to Phase 2-3 trials is vital to ensuring the interventions developed, implemented, and tested are not only empirically-based, but also culturally-responsive, attentive to DEIA, acceptable and relevant. Mothers provided valuable insights surrounding participation in THRIVE, highlighting important DEIA elements of THRIVE and suggested ways to decrease burden and increase access.

Racial and ethnic disparities in clinical trials for pediatric obesity

OBJECTIVE

The objective of this study was to examine the representation of historically marginalized racial and ethnic groups in pediatric obesity clinical trials.

METHODS

We performed a cross-sectional analysis of clinical trials in pediatric obesity (participants aged ≤18 years) that were registered in ClinicalTrials.gov, were completed from January 2013 to August 2023, and were conducted in the United States. We quantified disparities in trial enrollment by calculating the enrollment-prevalence disparity (EPD) for each racial and ethnic group.

RESULTS

A total of 260 trials met eligibility criteria, of which 128 trials (49.2%) reported race and/or ethnicity data. Enrollment of White, Hispanic, and Black children roughly reflects disease burden in these populations. However, relative to disease burden, Asian (EPD, -3.7%; IQR, -3.7% to 1.8%; p < 0.0001), American Indian and Alaska Native (EPD, -2.1%; IQR, -2.1% to -2.1%; p < 0.0001), and Native Hawaiian or other Pacific Islander (EPD, -0.6%; IQR, -0.6% to -0.6%; p < 0.0001) children were significantly underrepresented in these trials.

CONCLUSIONS

With the exception of Black and Hispanic children, historically marginalized racial groups were underrepresented in pediatric obesity trials, signifying a need to improve diversity of participants in these trials. Additionally, there are substantial gaps in the documentation of race and ethnicity information. Concerted efforts are needed to ensure adequate reporting of race and ethnicity information in clinical trials.

Parental Perceptions of Priorities and Features for a Mobile App to Promote Healthy Lifestyle Behaviors in Preschool Children: Mixed Methods Evaluation

BACKGROUND

Parents of preschool-aged children are a key focus for interventions to shape healthy lifestyle behaviors and support risk reduction for obesity from an early age. In light of limited existing evidence on the use of mobile technology to promote healthy lifestyle behaviors among young children, we sought to gather parental priorities regarding a mobile app focused on guided goal setting across the domains of diet, physical activity, media use, and sleep.

OBJECTIVE

The purpose of this study was to explore the priorities and needs of parents of 2- to 5-year-old children to guide developing the content and features of a mobile app aimed at promoting healthy lifestyle behaviors using a novel convergent mixed methods approach.

METHODS

From November to December 2021, we invited parents or guardians in Kentucky to complete a series of web-based concept mapping activities and semistructured interviews (total N=30). Using 2 lists of items focused on (1) parental priorities (content areas) and (2) application features, we asked participants to conduct concept mapping procedures for each list: a web-based sorting activity, where participants grouped items together into thematic piles that made sense to them, and a rating activity, where participants rated each item on a 5-point Likert-type scale. The qualitative interviews were transcribed verbatim, coded, and then analyzed by constant comparative analysis to identify themes. We used the quantitative findings from the concept mapping process to triangulate the resulting themes from the qualitative interviews and generate possible app content areas and features.

RESULTS

The concept mapping results resulted in two 3-cluster concept maps. For parental priorities, participants identified the clusters Creating Healthy Eating Habits, Forming Boundaries, and Building Good Relationships; for app features, participant clusters included Eating Healthy, Using the App, and Setting Goals. The interview themes also represented those 2 domains. Overall, the participants indicated that the top priorities were general health and wellbeing, routine and setting boundaries, and food and healthy eating when it comes to building healthy behaviors among their preschool-aged children. Parents indicated that quick, easy, and child-friendly recipes, goal tracking, and the use of tips and notifications were the features they valued most.

CONCLUSIONS

This study contributes to the understanding of what parents or caregivers of young children want from mobile apps, in both content and features, to support building healthy behaviors and routines. The findings can inform future research on the development and evaluation of existing or new mobile apps. Specific app features identified to meet family needs should be designed closely with a diverse set of families and tested using rigorous designs to identify the mechanisms of action that mobile apps may use for efficacious healthy parenting outcomes.

Psychosocial Correlates of Childhood Body Mass Index: Racial and Ethnic Differences

Objective

To examine racial/ethnic differences in the associations of family socioeconomic status (SES), neighborhood SES, and inhibitory control with body mass index (BMI) in 9-10-year-old children using data from the Adolescent Brain Cognitive Development (ABCD) study.

Methods

This cross-sectional study included a diverse sample of children aged 9-10 years, representing non-Latino White, Black, Latino, Asian, and Other racial/ethnic groups. BMI was the primary outcome. Key predictors were family SES, neighborhood SES, and inhibitory control. Multivariable regression models were stratified by race/ethnicity to identify group-specific associations.

Results

Race/ethnic groups differed in psychosocial correlates of childhood BMI at age 9 and 10. Among non-Latino White children, higher family income (B = -0.086, p < 0.001), higher parental education (B = -0.069, p < 0.001), and living in a married household (B = -0.079, p < 0.001) were associated with lower BMI. Additionally, the presence of healthy food options in the zip code (B = -0.030, p = 0.032) was linked to lower BMI, while lack of planning (B = 0.032, p = 0.030) was associated with higher BMI. For non-Latino Black children, positive urgency (B = -0.068, p = 0.022) was negatively associated with BMI, while other factors such as family SES and neighborhood SES did not show significant associations. For Latino children, higher family income (B = -0.093, p = 0.001) and parental education (B = -0.099, p < 0.001) were associated with lower BMI. In this group, male gender (B = 0.043, p = 0.033) was associated with higher BMI. Among Asian children, higher family income (B = -0.199, p = 0.006) and parental education (B = -0.144, p = 0.037) were significantly associated with lower BMI. For children in the "Other" racial/ethnic category, higher family income (B = -0.101, p = 0.023), living in a married household (B = -0.076, p = 0.026), and higher median income in the zip code (B = -0.083, p = 0.013) were associated with lower BMI. In this group, male children had lower BMI compared to females (B = -0.089, p = 0.001).

Conclusion

The findings highlight substantial racial/ethnic differences in the psychosocial and socioeconomic correlates of BMI in children. There is a need for tailored interventions that target social determinants of childhood high BMI. One size does not fit all.

Sex Differences in Diet and Physical Activity Behaviors Among Racial/Ethnic Minority Adolescents with High Metabolic Risk

Certain dietary and physical activity (PA) behaviors may differentially predispose male and female adolescents to obesity and diabetes; however, sex differences in dietary and PA behaviors and in factors that impact these behaviors (e.g., self-efficacy, social support) in this population remain unknown. Using data from a community-based adolescent diabetes prevention intervention conducted in East Harlem in New York City, we examined sex differences in baseline characteristics including clinical measurements, lifestyle behaviors, and behavioral determinants. Among 147 overweight/obese adolescents aged 13-19 years, 61.9% were girls, 69.7% were of Hispanic ethnicity, 24.8% were non-Hispanic Black, and 60.5% were diagnosed with prediabetes. Boys had higher metabolic risk scores than girls (3.8 vs. 3.3, p = 0.002) despite girls reporting more perceived barriers to healthy eating and PA. Boys reported doing more moderate to vigorous PA but also had more sedentary behaviors than girls. Boys reported higher self-efficacy and more peer support for PA. Girls reported more depressive symptoms and were more likely to compare their body images to those in magazines/social media. Overall, among a sample of urban adolescents with high metabolic risk, we found significant sex differences in many dietary and PA behaviors and related factors, which could be used to inform tailored strategies for weight management to reduce cardiometabolic risk among youth from similar high-risk populations.

Race as social determinant of growth and body composition among infants born very preterm

OBJECTIVE

Racism leads to disparities in health outcomes. Our objective was to determine if black race was independently associated with differences in fat accretion at discharge in a large cohort of very preterm infants (32 weeks of gestation or less).

METHODS

De-identified demographic, anthropometric and body composition data were collected from seven neonatal units around the United States. Weight, length, and head circumference z-scores at birth and at the time of body composition assessment or hospital discharge were calculated.

RESULTS

The median gestational age and birthweight for this cohort (n = 888) were 29 weeks [IQR, 27-30] and 1167 g [SD, 354], respectively. The study population included 53% black preterm infants. Birthweight was lower in black preterm infants compared with white infants (1112 ± 334 g vs. 1228 ± 366 g; p < 0.0001). After adjusting for birthweight, gestational age, and birthweight-for-age z-score, black preterm infants had more weight gain (adjusted mean difference: 0.5 g/kg/day; p = 0.03) but not higher BF% z-scores at hospital discharge (adjusted mean: 1.2 vs. 1.3; p = 0.14) than white infants.

CONCLUSIONS

After adjusting for covariates, black race was associated with higher weight gain velocity but not higher BF% z-scores.

IMPACT

This study presents findings from a large-scale multicenter cohort. Racial differences were observed in birth weight and the rate of weight gain; however, these differences were not associated with dissimilarities in body composition outcomes. Understanding nutrition and growth outcomes across racial groups is necessary to combat racial disparities in the neonatal intensive care unit (NICU).

Validation of Variables for Use in Pediatric Obesity Risk Score Development in Demographically and Racially Diverse United States Cohorts

OBJECTIVE

To evaluate the performance of childhood obesity prediction models in four independent cohorts in the United States, using previously validated variables obtained easily from medical records as measured in different clinical settings.

STUDY DESIGN

Data from four prospective cohorts, Latinx, Eating, and Diabetes; Stress in Pregnancy Study; Project Viva; and Center for the Health Assessment of Mothers and Children of Salinas were used to test childhood obesity risk models and predict childhood obesity by ages 4 through 6, using five clinical variables (maternal age, maternal prepregnancy body mass index, birth weight Z-score, weight-for-age Z-score change, and breastfeeding), derived from a previously validated risk model and as measured in each cohort's clinical setting. Multivariable logistic regression was performed within each cohort, and performance of each model was assessed based on discrimination and predictive accuracy.

RESULTS

The risk models performed well across all four cohorts, achieving excellent discrimination. The area under the receiver operator curve was 0.79 for Center for the Health Assessment of Mothers and Children of Salinas and Project Viva, 0.83 for Stress in Pregnancy Study, and 0.86 for Latinx, Eating, and Diabetes. At a 50th percentile threshold, the sensitivity of the models ranged from 12% to 53%, and specificity was ≥ 90%. The negative predictive values were ≥ 80% for all cohorts, and the positive predictive values ranged from 62% to 86%.

CONCLUSION

All four risk models performed well in each independent and demographically diverse cohort, demonstrating the utility of these five variables for identifying children at high risk for developing early childhood obesity in the United States.

The neighborhood food environment modifies the association between infant feeding and childhood obesity

BACKGROUND

The Special Supplemental Nutrition Program for Women, Infants and Children (WIC) issues infant formula to infants who are not fully breastfed, and prior research found elevated obesity risk among children receiving lactose-reduced infant formula with corn syrup solids (CSSF) issued by WIC. This study was conducted to evaluate associations between a broader set of specialty infant formulas issued by WIC and child obesity risk, whether neighborhood context (e.g. neighborhood food environment) modifies associations, and whether racial/ethnic disparities in obesity are partly explained by infant formula exposure and neighborhood context.

METHODS

WIC administrative data, collected from 2013-2020 on issued amount (categorical: fully formula fed, mostly formula fed, mostly breastfed, fully breastfed) and type of infant formula (standard cow's milk formula, and three specialty formulas: any CSSF, any soy-based formula, and any cow's milk-based formula with added rice starch) and obesity at ages 2-4 years (defined as a Body Mass Index z-score ≥ 95th percentile according to World Health Organization growth standard) were used to construct a cohort (n = 59,132). Associations of infant formula exposures and race/ethnicity with obesity risk were assessed in Poisson regression models, and modification of infant feeding associations with obesity by neighborhood context was assessed with interaction terms.

RESULTS

Any infant formula exposure was associated with significantly higher obesity risk relative to fully breastfeeding. Receipt of a CSSF was associated with 5% higher obesity risk relative to the standard and other specialty infant formulas (risk ratio 1.05, 95% confidence interval 1.02, 1.08) independent of breastfeeding duration and receipt of other specialty infant formulas. The association between CSSF and obesity risk was stronger in neighborhoods with healthier food environments (10% higher risk) compared to less healthy food environments (null). Racial/ethnic disparities in obesity risk were robust to adjustment for infant formula exposure and neighborhood environment.

CONCLUSIONS

Among specialty infant formulas issued by WIC, only CSSFs were associated with elevated obesity risk, and this association was stronger in healthier food environments. Future research is needed to isolate the mechanism underlying this association.

Understanding risk and causal mechanisms for developing obesity in infants and young children: A National Institutes of Health workshop

Obesity in children remains a major public health problem, with the current prevalence in youth ages 2-19 years estimated to be 19.7%. Despite progress in identifying risk factors, current models do not accurately predict development of obesity in early childhood. There is also substantial individual variability in response to a given intervention that is not well understood. On April 29-30, 2021, the National Institutes of Health convened a virtual workshop on "Understanding Risk and Causal Mechanisms for Developing Obesity in Infants and Young Children." The workshop brought together scientists from diverse disciplines to discuss (1) what is known regarding epidemiology and underlying biological and behavioral mechanisms for rapid weight gain and development of obesity and (2) what new approaches can improve risk prediction and gain novel insights into causes of obesity in early life. Participants identified gaps and opportunities for future research to advance understanding of risk and underlying mechanisms for development of obesity in early life. It was emphasized that future studies will require multi-disciplinary efforts across basic, behavioral, and clinical sciences. An exposome framework is needed to elucidate how behavioral, biological, and environmental risk factors interact. Use of novel statistical methods may provide greater insights into causal mechanisms.

Es Niño o Niña?: Gender Differences in Feeding Practices and Obesity Risk among Latino Infants

Background

Obesity prevalence is significantly higher among Latino boys than girls. Weight status at 12 mo, a significant predictor of childhood obesity, is associated with feeding practices during infancy.

Objectives

The objectives were to examine breastfeeding and formula-feeding practices overall and by infant gender and to examine relations among infant gender, milk-feeding practices, and obesity risk among Latino infants over the first year of life.

Methods

Latino mother-infant dyads (n = 90) were recruited from a pediatric clinic. Mothers were interviewed at regular intervals (infants aged 2, 4, 6, and 9 mo), and 24-h feeding recalls were conducted when infants were aged 6 and 9 mo. Infants' lengths and weights were retrieved from clinic records to calculate weight-for-length percentiles. A bivariate analysis was conducted to compare feeding practices by gender and mediation analysis to test whether feeding practices mediated the relation between gender and obesity risk.

Results

The majority (80%) of mothers were born outside the United States. In early infancy, mixed feeding of formula and breastfeeding was common. At 6 and 9 mo of age, milk-feeding practices differed, with formula feeding more common for boys than girls. At 12 mo, 38% of infants experienced obesity risk (≥85th weight-for-length percentile). Infants' obesity risk increased by 18% per 1 oz increase in powdered formula intake. Formula intake among boys was on average 1.42 oz (in dry weight) higher than that among girls, which, in turn, mediated their increased obesity risk (IERR = 1.27, 95% confidence interval: 1.02, 1.90).

Conclusions

The increased obesity risk among Latino boys compared with girls at 12 mo was explained by higher rates of formula feeding at 6 and 9 mo of age. Future investigations of cultural values and beliefs in gender-related feeding practices are warranted to understand the differences in obesity risk between Latino boys and girls.

Breastfeeding duration and associations with prevention of accelerated growth among infants from low-income, racially and ethnically diverse backgrounds

OBJECTIVE

To describe breastfeeding rates from early to late infancy and to examine associations between breastfeeding duration and infant growth, including rapid weight gain (RWG, > 0·67 SD increase in weight-for-age Z-score), among infants from low-income, racially and ethnically diverse backgrounds.

DESIGN

A short, prospective cohort study was conducted assessing breastfeeding status at infant ages 2, 4, 6, 9 and 12 months. Infant length and weight measurements were retrieved from electronic health records to calculate weight-for-length Z-scores and the rate of weight gain.

SETTING

Pediatric clinic in the Southeastern USA.

PARTICIPANTS

Mother-infant dyads (n = 256).

RESULTS

Most participants were African American (48 %) or Latina (34 %). Eighty-one per cent were participating in the Special Supplemental Nutrition Program for Women, Infants and Children. Infants were breastfed for a median duration of 4·75 months, with partial more common than exclusive breastfeeding. At 12 months, 28 % of the participants were breastfeeding. Infants breastfed beyond 6 months had significantly lower growth trajectories than infants breastfed for 0-2 months (β = 0·045, se = 0·013, P = 0·001) or 3-6 months (β = 0·054, se = 0·016, P = 0·001). Thirty-six per cent of the infants experienced RWG. RWG was more common among infants who were breastfed for 2 months or less than 6+ month breastfed group (relative risk = 1·68, CI95 (1·03, 2·74), P = 0·03).

CONCLUSIONS

Breastfeeding beyond 6 months is associated with the prevention of accelerated growth among infants from low-income, racially and ethnically diverse backgrounds, suggesting progress toward health equity.

Maternal stress and early childhood BMI among US children from the Environmental influences on Child Health Outcomes (ECHO) program

BACKGROUND

We aimed to understand the association between maternal stress in the first year of life and childhood body mass index (BMI) from 2 to 4 years of age in a large, prospective United States-based consortium of cohorts.

METHODS

We used data from the Environmental influences on Child Health Outcomes program. The main exposure was maternal stress in the first year of life measured with the Perceived Stress Scale (PSS). The main outcome was the first childhood BMI percentile after age 2 until age 4 years. We used an adjusted linear mixed effects model to examine associations between BMI and PSS quartile.

RESULTS

The mean BMI percentile in children was 59.8 (SD 30) measured at 3.0 years (SD 1) on average. In both crude models and models adjusted for maternal BMI, age, race, ethnicity, infant birthweight, and health insurance status, no linear associations were observed between maternal stress and child BMI.

CONCLUSIONS

Among 1694 maternal-infant dyads, we found no statistically significant relationships between maternal perceived stress in the first year of life and child BMI after 2 through 4 years.

IMPACT

Although existing literature suggests relationships between parental stress and childhood BMI, we found no linear associations between maternal stress in the first year of life and childhood BMI at 2-4 years of age among participants in ECHO cohorts. Higher maternal stress was significantly associated with Hispanic ethnicity, Black race, and public health insurance. Our analysis of a large, nationally representative sample challenges assumptions that maternal stress in the first year of life, as measured by a widely used scale, is associated with offspring BMI.

Differences in Infant Diet Quality Index by Race and Ethnicity Predict Differences in Later Diet Quality

BACKGROUND

Racial and ethnic disparities in infant-feeding practices may negatively influence diet quality and health.

OBJECTIVES

This study investigated the racial, ethnic, and language (English or Spanish) differences in infant diet quality, later diet quality, and weight status at 2-5 y, and whether these differences were explained through infant diet quality among participants in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC).

METHODS

Using the WIC Infant and Toddler Feeding Practices Study-2 (unweighted n = 2663; weighted n = 362,712), relationships between the Infant Dietary Quality Index (IDQI; range 0-1) and Healthy Eating Index-2020 (HEI-2020; range 0-100) and BMI z-score (BMIz) at 2-5 y were analyzed by race, ethnicity, and language preference [Hispanic Spanish-speaking, Hispanic English-speaking, non-Hispanic (NH) White, and NH Black participants]. Statistical interaction between IDQI and each group was evaluated in multivariable models. The mediation of each group through the IDQI was assessed using causal mediation methods.

RESULTS

Differences in IDQI [mean (standard deviation)] were observed between Hispanic Spanish-speaking participants [0.41 (0.10)], Hispanic English-speaking participants [0.37 (0.10)], NH White participants [0.36 (0.10)], and NH Black participants [0.35 (0.09)], P < 0.001. Differences in HEI-2020 occurred at 2-5 y, with the Hispanic Spanish-speaking participants having consistently higher HEI-2020 scores. Differences in BMIz were observed at 5 y, with higher scores among Hispanic Spanish-speaking participants. Interaction between race, ethnicity, and IDQI was observed for all outcomes except for BMIz at 3 y. Through mediation, IDQI explained 13%-20% of the difference in HEI-2020 scores between Hispanic Spanish-speaking and NH White participants at 2-5 y. IDQI explained 22%-25% of the difference in HEI-2020 scores between the Hispanic Spanish-speaking and NH Black participants at 4 y and 5 y.

CONCLUSIONS

Higher infant diet quality scores observed in Hispanic Spanish-speaking participants explain some of the racial and ethnic differences observed in later diet quality, suggesting that improving infant diet quality may help reduce diet disparities during early childhood.

Prevalence and determinants of overweight and obesity among preschool-aged children from migrant and socioeconomically disadvantaged contexts in Montreal, Canada

Among migrant and socioeconomically disadvantaged preschool-aged children followed in social perinatal primary care services in Montreal, Canada, we estimated the prevalence of overweight/obesity and identified determinants of body mass index z-score (zBMI) at 4-5 years old. We conducted a retrospective cohort study using electronic medical records of 275 child-mother dyads followed from birth to 4-5 years. Anthropometric measures and established maternal, perinatal and child risk factors for childhood obesity were examined. Age- and sex-specific zBMI at 4-5-years were computed and categorized according to WHO standards. Linear regression with model averaging was used to identify early life factors associated with zBMI. At 4-5 years, children's weight status was classified as underweight (1.5%), normal weight (69.7%), at-risk-of-overweight (19.2%), overweight (6.9%), and obesity (2.7%). Primiparity (0.51, 95% CI 0.24; 0.78), higher birthweight (1.04, 95% CI 0.70; 1.37), accelerated weight gain in the first year of life (0.21, 95% CI 0.13; 0.31), and introduction to solid foods before 6 months (0.89, 95% CI 0.42; 1.36) were associated with a higher zBMI, while less than high school education (-0.50, 95% CI -0.95; -0.05) and higher gestational age (-0.14, 95% CI -0.21; -0.05) were associated with lower zBMI at 4-5 years. Overweight/obesity is prevalent among preschool-aged children from migrant and socioeconomically disadvantaged contexts and is associated with known risk factors. Future research is needed to better understand the role of social perinatal primary care services in promoting optimal weight gain among children living in contexts of vulnerability.

Addressing Inequalities in Breast Cancer Care Delivery

Breast cancer treatment, timeliness of care, and clinical outcomes are inferior for patients of Black race and Hispanic ethnicity, and the origin of these inequities is multifactorial. Owing to aggregate reporting of data in the United States for patients of Asian, Native Hawaiian, and Pacific Islander ancestry, disparities within and across these groups are difficult to appreciate. In large part due to low prevalence, male breast cancer remains understudied, and treatment algorithms are primarily extrapolated from research conducted in female patients.

Glycemic Measures in Childhood as Predictors of Future Diabetes-Related Microvascular Complications in an Indigenous American Population

OBJECTIVE

To examine the role of glycemic measures performed during childhood in predicting future diabetes-related nephropathy and retinopathy in a high-risk indigenous American cohort.

RESEARCH DESIGN AND METHODS

We studied associations between glycated hemoglobin (HbA1c) and 2-h plasma glucose (PG), measured during childhood (age 5 to <20 years) in a longitudinal observational study of diabetes and its complications (1965-2007), and future albuminuria (albumin creatinine ratio [ACR] ≥30 mg/g), severe albuminuria (ACR ≥300 mg/g), and retinopathy (at least one microaneurysm or hemorrhage or proliferative retinopathy on direct ophthalmoscopy). Areas under the receiver operating characteristic curve (AUCs) for childhood glycemic measures when predicting nephropathy and retinopathy were compared.

RESULTS

Higher baseline levels of HbA1c and 2-h PG significantly increased the risk of future severe albuminuria (HbA1c: hazard ratio [HR] 1.45 per %; 95% CI 1.02-2.05 and 2-h PG: HR 1.21 per mmol/L; 95% CI 1.16-1.27). When categorized by baseline HbA1c, children with prediabetes had a higher incidence of albuminuria (29.7 cases per 1,000 person-years [PY]), severe albuminuria (3.8 cases per 1,000 PY), and retinopathy (7.1 cases per 1,000 PY) than children with normal HbA1c levels (23.8, 2.4, and 1.7 cases per 1,000 PY, respectively); children with diabetes at baseline had the highest incidence of the three complications. No significant differences were observed between AUCs for models with HbA1c, 2-h PG, and fasting PG when predicting albuminuria, severe albuminuria, or retinopathy.

CONCLUSIONS

In this study, higher glycemia levels ascertained by HbA1c and 2-h PG during childhood were associated with future microvascular complications; this demonstrates the potential utility of screening tests performed in high-risk children in predicting long-term health outcomes.

Evaluation of Commercially Available Infant-feeding Mobile Applications Using App Quality Evaluation Tool

OBJECTIVE

Assess the quality of free, commercially available infant-feeding mobile applications (apps) and their appropriateness for audiences with low income and of racial and ethnic diversity using the App Quality Evaluation tool.

METHODS

Researchers selected apps using an iterative process (n = 6). Health professionals (n = 10) who work with mothers with infants and low income who completed the App Quality Evaluation tool for each app, consisting of 7 domains of app quality. Average domain scores were calculated for each app (> 8 indicates high quality).

RESULTS

Evaluators highly rated app function and purpose for WebMD Baby (8.0 ± 1.8 and 8.2 ± 0.9, respectively) and Baby Center (8.0 ± 2.1 and 8.0 ± 2.6, respectively). For other apps, no domains were highly rated. No apps were rated highly for appropriateness (range 5.7-7.7) nor provided high-quality infant-feeding information for mothers with low income. Few apps were rated highly appropriate for mothers who are Black or Hispanic.

CONCLUSIONS AND IMPLICATIONS

Commercially available infant-feeding apps are of limited quality, indicating the need to develop high-quality apps for audiences with low income and Black and Hispanic identities.

Longitudinal associations between sleep and weight status in infants and toddlers

BACKGROUND

The limited research assessing relationships between sleep duration and weight status in infants and toddlers relies primarily on parent-reported sleep and cross-sectional studies.

OBJECTIVES

Examine whether average sleep duration and changes in sleep duration among 6-24-month-old children were associated with weight-for-length z-scores, and whether these associations varied by race/ethnicity, socioeconomic status and sex.

METHODS

Data were collected when children were approximately 6, 12, 18 and 24 months old (N = 116). Sleep duration was measured using actigraphy. Weight-for-length z-scores were calculated using children's height and weight. Physical activity was assessed using accelerometry. Diet was assessed using a feeding frequency questionnaire. Demographic characteristics included sex, race/ethnicity and socioeconomic status. Separate associations of between- and within-person changes in sleep duration were estimated with weight-for-length z-score treated as the outcome variable in linear mixed model analyses. Additional models were assessed that included interactions between sleep and demographic characteristics.

RESULTS

At time points where children slept longer at night compared to their own average, their weight-for-length z-score was lower. This relationship was attenuated by physical activity levels.

CONCLUSIONS

Increasing sleep duration can improve weight status outcomes in very young children who have low physical activity levels.

Developmental Contributions to Obesity: Nutritional Exposures in the First Thousand Days

Obesity is prevalent and continuing to rise across all age groups, even children. As obesity is challenging to manage and treat, prevention is critical. Here, we highlight nutritional influences during periods of early developmental plasticity, namely the prenatal period and infancy, that have been shown to contribute to the development of obesity into childhood and beyond. We review recent research that examines maternal nutritional factors including dietary patterns and quality, as well as the infant diet, such as complementary foods and beverages, that influence long-term obesity risk. We end with recommendations for clinicians.

A Mixed-Methods Analysis of a Special Supplemental Nutrition Program for Women, Infants, and Children and Primary Care Partnership to Promote Responsive Feeding for Infants in Group Well-Child Care

OBJECTIVE

To evaluate the Healthy Eating through Group Well-Child Care (GWCC) intervention, a Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) and primary care partnership which seeks to promote responsive feeding practices among low-income caregivers, by examining its impact on infant growth and exploring the experiences of caregivers who participated in this intervention.

METHODS

Using a difference-in-differences approach, we examined change in weight-for-length among infants in GWCC before versus after implementation of the intervention compared with infants in individual well-child care (IWCC) over the same time-period. In parallel, we conducted semi-structured interviews in English and Spanish with caregivers who participated in the intervention to explore their perspectives and analyzed transcripts via the constant comparative method to identify salient themes.

RESULTS

Using electronic health record data from 279 GWCC and 6134 IWCC participants, we found no significant difference in first-year weight-for-length trajectory associated with participation in the intervention. We reached thematic saturation after 19 interviews with 22 caregivers and identified four major themes around feeding: 1) structural barriers limit access to healthy foods through WIC, 2) conflicting sources of nutrition advice challenge parental decision making, 3) exposure to novel foods facilitated further experimentation with healthier foods, and 4) discussion of responsive feeding facilitated awareness and adoption.

CONCLUSIONS

A primary care and WIC partnership to promote responsive feeding in the context of GWCC was well received by caregivers but was not associated with improved weight-for-length among infants. Structural barriers to implementing responsive feeding and healthy eating practices may have impacted lack of measurable results from the intervention.

Obesity and Overweight Among Children With Medical Complexity

OBJECTIVES

To assess the prevalence of overweight or obesity among children with medical complexity (CMC), compared with children without medical complexity, and explore potentially modifiable mechanisms.

METHODS

This study involved a retrospective cohort of 41 905 children ages 2 to 18 seen in 2019 at a single academic medical center. The primary outcome was overweight or obesity, defined as a body mass index of ≥85% for age and sex. CMC was defined as ≥1 serious chronic condition in ≥1 system. Obesogenic conditions and medications were defined as those typically associated with excess weight gain. Multivariable logistic regression was used to adjust for common confounders.

RESULTS

Of the children in the cohort, 29.5% were CMC. Overweight or obesity prevalence was higher among CMC than non-CMC (31.9% vs 18.4%, P ≤.001, adjusted odds ratio [aOR] 1.27, 95% confidence interval [CI] 1.20-1.35). Among CMC, the risk for overweight or obesity was higher among children with metabolic conditions (aOR 2.09, 95% CI 1.88-2.32), gastrointestinal conditions (aOR 1.23 95% CI 1.06-1.41), malignancies (aOR 1.21 95% CI 1.07-1.38), and Spanish-speaking parents (aOR 1.47 95% CI 1.30-1.67). Among overweight or obese CMC, 91.6% had no obesogenic conditions, and only 8.5% had been seen by a registered dietitian in the previous year.

CONCLUSIONS

CMC are significantly more likely to be overweight or obese when compared with children without medical complexity. Although many CMC cases of overweight appear to be preventable, further research is necessary to determine if and how to prevent comorbid obesity among CMC.

Process and effect evaluation of the app-based parenting program Samen Happie! on infant zBMI: A randomized controlled trial

Background

Although energy balance-related parenting practices are regarded critical components in the prevention of childhood obesity, most programs targeting parenting practices with respect to a wide range of energy balance-related behaviors were not aimed at high-risk families with a lower socioeconomic position (SEP).

Objective

The Samen Happie! app-based program aimed to stimulate healthy child weight development especially among families with a lower SEP, by encouraging healthy energy balance-related parenting practices.

Methods

A two-armed randomized controlled trial examined the process and effectiveness of the Samen Happie! program on child zBMI outcomes at 6- and 12-months follow-up. In total, 357 Dutch parents with infants aged 5-15 months old at baseline participated. Parents in the app condition (n = 179) received access to the Samen Happie! app and were compared to a waitlist-control condition (n = 178). Changes in zBMI were examined through linear mixed-effects models based on intention-to-treat and exploratory per-protocol principles.

Results

Process data showed low levels of sustained app use and moderate app acceptability. A general increase in child zBMI was observed in both conditions after 6 and 12 months. Intention-to-treat analyses using multiple imputations showed several statistically significant differences between conditions and high-risk subgroups. Specifically, at 6-months follow-up, zBMI increase was least pronounced in the app condition among children of parents with lower educational level. These findings were supported by exploratory per-protocol analyses including only frequent app users. In addition, per-protocol analyses showed benefits of app use at 6-months follow-up for children of parents with higher BMI. However, these effects were reversed at 12-months follow-up in both intention-to-treat and per-protocol analyses, where children of parents in the app condition in general increased the most in zBMI.

Conclusions

This study suggests that the Samen Happie! program might prevent zBMI increases after 6 months among children of parents with lower educational level, and children of parents with higher BMI who more frequently use the app. However, the app did not prevent increases in zBMI after 12 months. Future research should investigate strategies to increase sustained app use and engagement in mHealth parenting programs for childhood obesity as well as options to combine app-based programs with additional support strategies aimed at high-risk families.

Perceived factors that influence adoption, implementation and sustainability of an evidence-based intervention promoting healthful eating and physical activity in childcare centers in an urban area in the United States serving children from low-income, racially/ethnically diverse families

Introduction

Early childcare centers offer optimal settings to provide healthy built environments where preschool age children spend a majority of their week. Many evidence-based interventions (EBIs) promoting healthful eating and physical activity for early childcare settings exist, but there is a limited understanding of how best to support adoption, implementation and sustainability in community settings. This study examined how early childcare teachers and administrators from Chicago-area childcare centers serving children from low-income, racially/ethnically diverse communities viewed an EBI called Hip to Health (H3), and the factors they perceived as relevant for EBI adoption, implementation, and sustainability.

Methods

A multiple methods study including key informant interviews and a brief survey was conducted. Key informant interviews with teachers and administrators from childcare centers located in Chicago, IL were completed between December 2020 and May 2021. An interview guide and coding guide based on the Consolidated Framework for Implementation Research (CFIR) was developed. Interview transcripts were team coded in MAXQDA Qualitative Data Analysis software. Thematic analysis was used to identify findings specific to adoption, implementation, and sustainability. Participants were also asked to respond to survey measures about the acceptability, feasibility, and appropriateness of H3.

Results

Overall, teachers (n = 20) and administrators (n = 16) agreed that H3 was acceptable, appropriate, and feasible. Low start-up costs, ease-of-use, adaptability, trialability, compatibility, and leadership engagement were important to EBI adoption. Timely and flexible training was critical to implementation. Participants noted sustainability was tied to low ongoing costs, access to ongoing support, and positive observable benefits for children and positive feedback from parents.

Conclusions

These findings suggest that EBIs suitable for adoption, implementation, and sustainment in childcare centers serving racially/ethnically diverse, low-income families should be adaptable, easy to use, and low-cost (initial and ongoing). There is also some evidence from these findings of the heterogeneity that exists among childcare centers serving low-income families in that smaller, less resourced centers are often less aware of EBIs, and the preparation needed to implement EBIs. Future research should examine how to better support EBI dissemination and implementation to these settings.

Childhood obesity risk factors by race and ethnicity

OBJECTIVE

Childhood obesity is a public health concern that often worsens with age. Although several risk factors at the child and maternal levels have been identified in cross-sectional studies, less is known about their long-term contribution to racial/ethnic disparities in childhood obesity. This study examines child- and maternal-level factors associated with the growth trajectories of White, Black, and Latino children.

METHODS

Group-based trajectory models were used to identify BMI z score trajectories from birth to 9 years of age among White, Black, and Latino children. The associations of child- and maternal-level factors with the trajectory group identified as at risk for obesity were examined using adjusted logistic regression analysis, stratified by race/ethnicity.

RESULTS

Among White children, fast-food consumption (odds ratio [OR] = 1.66; 95% CI: 1.09-2.52) was associated with higher odds of following an at-risk trajectory. Among Black and Latino children, prepregnancy BMI was associated with following an at-risk trajectory (OR = 1.05; 95% CI: 1.03-1.08 for Black children, and OR = 1.12; 95% CI: 1.07-1.17 for Latino children).

CONCLUSIONS

These findings showed racial/ethnic differences in the risk factors that influence the likelihood of obesity during childhood. Further research is needed to identify modifiable racial/ethnic specific risk factors to guide obesity-prevention interventions.

A qualitative study on the perspectives of Turkish mothers and grandmothers in the Netherlands regarding the influence of grandmothers on health related practices in the first 1000 days of a child's life

BACKGROUND

Given the importance of the first 1000 days of a child's life in terms of laying the foundations for healthy growth and development, parents are a logical target group for supporting health-related practices with regard to young children. However, little attention is paid to the influence of the wider social community on the health and development of young children during this crucial period. This includes grandmothers, who often have a significant influence on health-related practices of their grandchildren. The aim of this study was therefore to explore the influence of grandmothers on health related practices of their grandchildren during the first 1000 days, from the perspectives of both grandmothers and mothers with a Turkish background.

METHOD

This qualitative study in the Netherlands collected data during focus group discussions with grandmothers (N = 3), interviews with grandmothers (N = 18) and interviews with mothers (N = 16), all with a Turkish background. Data was collected in the period between June 2019 and April 2021 and analysed using a thematic content analysis.

RESULTS

The influence of grandmothers and the wider social community on health related practices during the first 1000 days of a child's life is substantial and self-evident. The support of grandmothers is often rooted in various socio-cultural norms and practices. The mothers of young children can experience the guidance and pressure they receive from grandmothers and the wider social community as quite stressful. Conflicting views and practices tend to arise between grandmothers and mothers when a grandmother babysits. Both mothers and grandmothers often find it difficult to discuss these differences openly, for fear this might lead to a family conflict.

CONCLUSION

This study shows that grandmothers and the wider social community play an influential role in supporting a healthy first 1000 days of a child's life. The strong involvement of grandmothers may lead to tension between the mothers and grandmothers when their ideas about healthy practices are not in agreement and may lead to unhealthy practices. In targeting this wider social community, it is important to consider the various socio-cultural factors that underlie the advice, support, practices and beliefs of the individuals involved.

Obesity Incidence in U.S. Children and Young Adults: A Pooled Analysis

INTRODUCTION

Obesity prevalence among children and adolescents has risen sharply, yet there is a limited understanding of the age-specific dynamics of obesity as there is no single nationally representative cohort following children into young adulthood. Investigators constructed a pooled data set of 5 nationally representative panels and modeled age-specific obesity incidence from childhood into young adulthood.

METHODS

This longitudinal prospective follow-up used 718,560 person-years of observation in a pooled data set of 5 high-quality nationally representative panels-National Longitudinal Survey of Youth 1979 and 1997, National Longitudinal Study of Adolescent Health, and Early Childhood Longitudinal Study-Kindergarten cohorts of 1998 and 2011-constructed by the authors, covering 1980-2016. Differences in obesity incidence across birth cohorts and disparities in obesity incidence by sex and race/ethnicity (non-Hispanic Black, Hispanic, and non-Hispanic White) were tested in multivariate models. Data were analyzed from September 2018 to October 2021.

RESULTS

Obesity incidence increased by approximately 6% for each 1 year of age (hazard ratio=1.06, 95% CI=1.05, 1.07); however, incidence was nonlinear, exhibiting an inverted "U"-shaped pattern before 15 years of age and then rising from adolescence through 30 years. Obesity incidence more than doubled between the cohorts born in 1957-1965 and those born in 1974-1985 during adolescence. There was no significant change among those born in 1991-1994 and 2003-2006 up to age 15 years. Compared with non-Hispanic White children, non-Hispanic Black and Hispanic children had higher obesity incidence in all study cohorts. The magnitude of these disparities on the relative scale remained stable throughout the study period.

CONCLUSIONS

Although many children become obese before the age of 10, obesity incidence rises from about 15 years into early adulthood, suggesting that interventions are required at multiple developmental stages.

Latino Children's Obesity Risk Varies by Place of Birth: Findings from New York City Public School Youth, 2006-2017

Introduction: Research showing that place of birth (POB) predicts excess weight gain and obesity risk among Latino adults has not prompted similar research in Latino children, although childhood is a critical period for preventing obesity. Objective: To identify differences in obesity risk among Latino children by POB. Methods: Longitudinal cohort observational study on public school children self-identified by parent/guardian as Latino in grades K-12 for school years 2006-07 through 2016-17 with measured weight and height (n = 570,172_students; 3,103,642_observations). POB reported by parent/guardian was categorized as continental United States [not New York City (NYC)] (n = 295,693), NYC (n = 166,361), South America (n = 19,452), Central America (n = 10,241), Dominican Republic (n = 57,0880), Puerto Rico (n = 9687), and Mexico (n = 9647). Age- and sex-specific BMI percentiles were estimated based on established growth charts. Data were analyzed in 2020. Results: Prevalence of obesity was highest among US (non-NYC)-born girls (21%) and boys (27%), followed by NYC-born girls (19%) and boys (25%). Among girls, South Americans (9%) had the lowest prevalence of all levels of obesity, while Puerto Ricans (19%) and Dominicans (15%) had the highest prevalence. Among boys, South Americans also had the lowest prevalence of all levels of obesity (15%), while Puerto Ricans (22%) and Mexicans (21%) had the highest. In adjusted models, obesity risk was highest in US (non-NYC)-born children, followed by children born in NYC (p < 0.001). Immigrant Latino children exhibited an advantage even after controlling for individual and neighborhood sociodemographic features, particularly Dominicans, South Americans, and Puerto Ricans. Conclusions: The heterogeneity of obesity risk among Latino children highlights the importance of POB.

Maternal Stress and Excessive Weight Gain in Infancy

Rapid weight gain in infancy increases the risk of developing obesity early in life and contributes significantly to racial and ethnic disparities in childhood obesity. While maternal perceived stress is associated with childhood obesity, little is known about the impact it has on infant weight gain. Therefore, this study explores the impact of maternal perceived stress on change in weight-for-length (WFL) z-scores and the risk of rapid weight gain in infancy. We conducted a secondary data analysis of the longitudinal Nurture birth cohort (n = 666). Most mothers in the cohort were non-Hispanic/Latinx Black (71.6%). About one-half of mothers had a body mass index (BMI) greater than 25 prior to pregnancy, were unemployed, and had a low income. Most infants in the cohort were born full-term and were of normal weight. Data were collected at 3-, 6-, 9-, and 12-months postpartum. At each assessment, mothers completed the Cohen’s Perceived Stress Scale (PSS), and research assistants weighed and measured each infant. Tertiles were used to compare mothers with high and low perceived stress. A mixed model analysis of repeated measures assessed the associations between baseline perceived stress and the change in infant WFL z-scores over time. Log-binomial models assessed the association between baseline perceived stress and rapid weight gain, defined as a change in WFL z-score > 0.67 standard deviations from three to twelve months. Just under one-half of the infants (47%) experienced rapid weight gain between three and twelve months of age. Birthweight for gestational age (RR = 1.18, 95% CI = 1.08−1.29, p-value = 0.004), gestational age at birth (RR = 1.07, 95% CI = 1.01−1.14, p-value = 0.031), and weeks breastfed (0.99, 95% CI 0.99−1.00, p-value 0.044) were associated with risk of rapid weight gain in unadjusted analyses. WFL z-scores increased significantly over time, with no effect of perceived stress on change in WFL z-score or risk of rapid weight gain. Rapid weight gain in infancy was prevalent in this sample of predominately Black infants in the Southeastern US. We did not find evidence to support the hypothesis that maternal perceived stress influenced the risk of rapid weight gain. More work is needed to identify and assess the risk factors for rapid weight gain in infancy and to understand the role that maternal stress plays in the risk of childhood obesity so that prevention efforts can be targeted.

Barriers and facilitators to implementing practices for prevention of childhood obesity in primary care: A mixed methods systematic review

Primary care providers (PCPs) have an important role in prevention of excess weight gain in pre-school children. Guidelines exist to support PCPs' practices. This systematic review of PCPs' practice behaviors and their perceptions of barriers to and facilitators of implementation of guidelines was the first step toward the development of an intervention aimed at supporting PCPs. Five databases were searched to identify qualitative, quantitative, and mixed methods studies which examined PCPs' practice patterns and factors influencing implementation of recommended practices. The convergent integrated approach of the Joanna Briggs Institute (JBI) methodology for mixed methods reviews was used for data synthesis. Following analyses, the resultant factors were mapped onto the Capability, Opportunity, and Motivation model of Behaviour (COM-B). Fifty studies met the eligibility criteria. PCPs inconsistently implement recommended practices. Barriers and facilitators were identified at the provider (e.g., lack of knowledge), parent (e.g., lack motivation), and organization level (e.g., inadequate training). Factors were mapped to all three components of the COM-B model: psychological capability (e.g., lack of skills), reflective motivation (e.g., beliefs about guidelines), automatic motivation (e.g., discomfort), physical opportunity (e.g., time constraints), and social opportunity (e.g., stigma). These findings reflect the complexity of implementation of childhood obesity prevention practices.

Cultural adaptations of obesity-related behavioral prevention interventions in early childhood: A systematic review

Interventions for obesity prevention can effectively reduce obesity-related behaviors in young children. Understanding how to leverage and adapt evidence-based interventions is needed to improve reach among culturally and linguistically diverse families. This systematic review aimed to synthesize the approaches and outcomes of culturally adapted early childhood obesity-related behavioral prevention interventions. Multiple electronic databases were systematically searched in March 2021. All study designs were included if they reported cultural adaptations of an intervention targeting at least one obesity-related behavior (infant feeding, nutrition, physical activity, and/or sleep) among children aged 0-5 years. Studies that only conducted language translations or that developed new interventions were excluded. Two authors independently conducted critical appraisals using the Mixed Method Appraisal Tool. Findings were synthesized narratively, based on the Stages of Cultural Adaptation theoretical model and the Framework for Reporting Adaptations and Modifications-Enhanced. Twelve interventions met the inclusion criteria, with varied study designs. Few reported all aspects of cultural adaptation processes, and the cultural adaptation strategies documented varied. The results suggest that cultural adaptation of obesity-related behavioral prevention interventions targeting young children increases acceptability among target cultural groups, yet effectiveness is inconclusive due to a lack of trials. More detailed reporting of cultural adaptation processes and further effectiveness trials are needed to evaluate future work.

Racial differences in growth rates and body composition of infants born preterm

OBJECTIVE

To evaluate racial disparities in weight gain velocity and body composition among preterm infants.

STUDY DESIGN

This observational study analyzed race differences in fat-free mass (FFM), fat mass (FM), percent body fat (%BF), and weight gain at discharge of infants born at 25-32 weeks of gestation.

RESULTS

No racial differences in FFM, FM and %BF measurements were found between black and white preterm infants after adjusting for birth weight, gestational age, and the presence/absence of breastfeeding (n = 143). Black infants born preterm had lower birthweights and higher weight gain from birth to discharge in unadjusted and adjusted models (13 ± 3 vs. 11 ± 3 g/kg/day; <0.001).

CONCLUSION

Black infants had higher weight gain from birth to discharge, but comparable body composition measurements at discharge. More research is needed to understand contributing factors and long-term implications of this finding.

Grandparent Coresidence and Risk of Early Child Overweight and Obesity in Low-Income, Hispanic Families in New York City

OBJECTIVE

Children in low-income Hispanic families are at high risk of obesity and are more likely to live with grandparents than their non-Hispanic white counterparts. We aimed to determine if grandparent coresidence (prenatal through age 2 years) was associated with: 1) obesogenic feeding practices; and 2) child weight outcomes from birth to three years.

METHODS

We analyzed data from 267 low-income, Hispanic mother-infant pairs in the control group of an obesity prevention trial in New York City. Linear and logistic regression tested differences in obesogenic feeding practices and weight outcomes at 2 and 3 years, dependent upon grandparent coresidence. Multilevel modeling tested associations between grandparent coresidence and WFAz over time.

RESULTS

Persistent grandparent coresidence (vs none) was associated with putting cereal in the bottle (adjusted odds ratio [aOR] 3.46; 95% confidence interval [CI] 1.43, 8.40). Persistent grandparent coresidence (vs none) was associated with higher mean WFAz (2 years: B 0.83; 95% CI 0.41, 1.25; 3 years: B 0.79; 95% CI 0.32, 1.25) and higher odds of child overweight/obesity risk (2 years: aOR 4.38; 95% CI 1.64, 11.69; 3 years: aOR 3.15; 95% CI 1.19, 8.36). In multilevel models, more occasions of grandparent coresidence were associated with higher WFAz.

CONCLUSIONS

Grandparent coresidence may be associated with higher risk of child overweight/obesity in low-income, Hispanic families. Further research is needed to elucidate mechanisms of these associations and to inform obesity prevention strategies in the context of multigenerational families.

Regional and sociodemographic differences in average BMI among US children in the ECHO program

OBJECTIVE

The aim of this study was to describe the association of individual-level characteristics (sex, race/ethnicity, birth weight, maternal education) with child BMI within each US Census region and variation in child BMI by region.

METHODS

This study used pooled data from 25 prospective cohort studies. Region of residence (Northeast, Midwest, South, West) was based on residential zip codes. Age- and sex-specific BMI z scores were the outcome.

RESULTS

The final sample included 14,313 children with 85,428 BMI measurements, 49% female and 51% non-Hispanic White. Males had a lower average BMI z score compared with females in the Midwest (β = -0.12, 95% CI: -0.19 to -0.05) and West (β = -0.12, 95% CI: -0.20 to -0.04). Compared with non-Hispanic White children, BMI z score was generally higher among children who were Hispanic and Black but not across all regions. Compared with the Northeast, average BMI z score was significantly higher in the Midwest (β = 0.09, 95% CI: 0.05 to 0.14) and lower in the South (β = -0.12, 95% CI: -0.16 to -0.08) and West (β = -0.14, 95% CI: -0.19 to -0.09) after adjustment for age, sex, race/ethnicity, and birth weight.

CONCLUSIONS

Region of residence was associated with child BMI z scores, even after adjustment for sociodemographic characteristics. Understanding regional influences can inform targeted efforts to mitigate BMI-related disparities among children.

Cultural Influences on Healthy Weight Care in Karen Children

PURPOSE

Although the rates of childhood obesity are disproportionately higher in children of racial and ethnic minorities, research rarely addresses possible cultural factors. The purpose of this study was to discover cultural influences that contribute to or prevent childhood obesity from the perspectives of Burmese-American children and adolescents of Karen ethnicity in the southeast U.S.

DESIGN AND METHODS

The ethnonursing research method was used to seek perspectives of healthy weight care from Karen children between 8 and 15 years-of-age (n = 10). Karen parents (n = 5) and non-Karen community members (n = 13) were also interviewed. Data sources - interviews, fieldnotes, and observation notes - were analyzed using the four phases of the ethnonursing method.

RESULTS

Four themes important to healthy weight care in Karen children were discovered: views of a healthy child, food and food preparation, physical activity, and mutual support among family and community. These themes revealed both Karen and non-Karen influences.

CONCLUSIONS

Most Karen cultural influences promote healthy weight care in Karen children and adolescents which may protect them from childhood obesity. Lack of after-school transportation, limited space to play/exercise, and the sedentary tendencies of girls could limit healthy weight care.

PRACTICE IMPLICATIONS

Pediatric nurses may use knowledge gained from this study for promotion of healthy weight care in Karen families and to advocate for community changes which could benefit all children.

Preliminary assessment of the Healthy Beverage Index for U.S. Children and Adolescents: a tool to quantify the overall beverage intake quality of 2- to 19-year-olds

BACKGROUND

Improving beverage patterns of children and adolescents is recommended for combatting obesity and reducing disease risk. Therefore, it is important to assess beverage intake quality in this population. For adults, the Healthy Beverage Index (HBI) was created to assess beverage intake quality, but a similar tool did not exist for children and adolescents.

OBJECTIVE

The objective was to develop an HBI for U.S. Children and Adolescents (HBI-CA), and then assess the validity and reliability of this tool.

DESIGN

Modeled after the adult HBI, age-specific, evidence-based beverage recommendations were compiled. Ten components were included to assess beverage intake quality. Validity and reliability were assessed using cross-sectional data and methods similar to those used for the evaluation of the Healthy Eating Index.

PARTICIPANTS

The 2015-2016 National Health and Nutrition Examination Survey provided 24-hour dietary recall data for 2,874 children and adolescents aged 2-19 years.

MAIN OUTCOME MEASURES

HBI-CA scores were the main outcome measure.

STATISTICAL ANALYSES PERFORMED

To assess validity, independent t-tests were used to determine differences in HBI-CA component and total scores among groups, and principal component analysis (PCA) was completed to examine multidimensionality of the HBI-CA. Pearson's bivariate correlations were used to assess reliability.

RESULTS

The HBI-CA produced a (mean±standard error) total score of 69.2±0.8, which is similar to the adult HBI mean total score of 63. PCA identified six factors, indicating the multidimensionality of the HBI-CA, with more than one combination of components contributing to variation in total scores. Most HBI-CA components were significantly correlated to the total score, with met fluid requirements, total beverage energy, sugar-sweetened beverage, and water components demonstrating the strongest correlations (r ranged 0.335-0.735, P-value ≤0.01).

CONCLUSIONS

The results provide preliminary evidence to support the validity and reliability of the HBI-CA. If future research establishes the predictive validity and sensitivity of the HBI-CA, this tool could be useful to quantify the beverage intake quality of children and adolescents.

Engagement, satisfaction, retention and behavioural outcomes of linguistically diverse mothers and infants participating in an Australian early obesity prevention trial

BACKGROUND

Early obesity prevention research interventions in Australia generally expect participants to be able to communicate in English, but do not account for other languages. This study aimed to investigate engagement, satisfaction, retention and behavioural outcomes of linguistically diverse participants from a mainstream early childhood obesity prevention trial.

METHODS

Healthy Beginnings is a nurse-led intervention based in Sydney, supporting families with optimal infant feeding and active play via telephone. This secondary analysis assessed participant engagement in the nurse telephone calls (call completions), satisfaction and behavioural outcomes (6- and 12-month survey data) and retention (survey completions), in the first year of life according to participants' language spoken at home (English or other language).

RESULTS

Of 1155 mothers, 533 (46%) spoke a language other than English at home. Significantly fewer mothers speaking a language other than English completed the 6-month survey (79%) compared to those speaking English (84%), yet mothers speaking a language other than English who completed the program were more satisfied with the program overall. Significantly fewer mothers speaking a language other than English completed the final four nurse calls (of six) (56%-65%) compared to those speaking English (70%-80%). Adjusted odds ratios showed selected behavioural outcomes were significantly more positive for participants speaking English at home.

CONCLUSIONS

Healthy Beginnings trial participants who spoke a language other than English at home had less favourable engagement, retention and behavioural outcomes compared to those who spoke English. So what? Early obesity prevention interventions should consider cultural adaptations to improve engagement and effectiveness among culturally and linguistically diverse families.

Obesity in Early Childhood: Examining the Relationship among Demographic, Behavioral, Nutritional, and Socioeconomic Factors

Background: The present study sought to explore the combined relationship of physical activity, screen time, consumption of sugar-sweetened beverages, infant feeding practices, and demographic factors with obesity in early childhood. Methods: The current study included cross-sectional Kindergarten Health Survey data collected annually from 2012 to 2016. The sample included 7814 kindergarten students, with a mean age of 5.02 [standard deviation = 0.33]. A Multinomial Logistic Regression using body mass index as the dependent variable and select demographic traits, dietary practices, sedentary behaviors, and physical activity indicators as independent variables was used to assess relationship of aforementioned factors to obesity. Results: Children were more likely to be obese if they were non-Caucasian, male, lived in rural areas, lived at or below the poverty level, had public insurance, or lived in single-parent households. Children who received less than 30 minutes of physical activity 3 or fewer days per week, had more than 2 hours of daily screen time, consumed any amount of soda, and consumed anything other than breast milk at 6 months of age also had a higher probability of being obese. Conclusions: The findings from this study suggest that investments in prevention strategies are needed to address the behavioral patterns and socioeconomic disparities before kindergarten. Efforts that increase access to nutritious food, physical activity, and overall family wellness and education, such as high-quality early childhood education, could be feasible prevention approaches.

A qualitative study of providers' perceptions of parental feeding practices of infants and toddlers to prevent childhood obesity

Background

With a recent focus on establishing US Dietary Guidance for children ages 0 to 2 years old, the objective of this qualitative study was to determine misconceptions and barriers that prevent parents from implementing early childhood feeding and obesity prevention practices as reported by healthcare, community-based, and education providers.

Methods

Trained researchers conducted one-on-one qualitative phone interviews, using a semi-structured script, with early childhood health and education providers working with families of young children. Interviews were audiotaped, transcribed verbatim, and analyzed using the classic analysis approach. Transcripts were coded by researchers and analyzed for themes.

Results

Providers (n = 21) reported commonly observed obesogenic practices including overfeeding tendencies, early initiation of solids or less optimal feeding practices, lack of autonomy and self-regulation by child, and suboptimal dietary patterns. Sources of parental misconceptions about feeding were often related to cultural, familial, and media influences, or lack of knowledge about optimal feeding practices for infants or toddlers.

Conclusions

Providers indicated a need for engaging and consistent child feeding and obesity prevention education materials appropriate for diverse cultural and literacy levels of parents, with detailed information on transitioning to solid foods. Early education and community-based providers reported limited access to evidence-based educational materials more so than healthcare providers. It is an opportune time to develop reputable and evidence-based child feeding guidance that is readily available and accessible for parents of infants and toddlers to prevent early childhood obesity.

An App-Based Parenting Program to Promote Healthy Energy Balance-Related Parenting Practices to Prevent Childhood Obesity: Protocol Using the Intervention Mapping Framework

BACKGROUND

The family environment plays an important role in the development of children's energy balance-related behaviors. As a result, parents' energy balance-related parenting practices are important targets of preventive childhood obesity programs. Families with a lower socioeconomic position (SEP) may benefit from participating in such programs but are generally less well reached than families with a higher SEP.

OBJECTIVE

This paper describes the application of the Intervention Mapping Protocol (IMP) for the development of an app-based preventive intervention program to promote healthy energy balance-related parenting practices among parents of children (aged 0-4 years) with a lower SEP.

METHODS

The 6 steps of the IMP were used as a theory- and evidence-based framework to guide the development of an app-based preventive intervention program.

RESULTS

In step 1, behavioral outcomes for the app-based program (ie, children have a healthy dietary intake, sufficient sleep, and restricted screen time and sufficient physical activity) and sociocognitive (ie, knowledge, attitudes, and self-efficacy) and automatic (ie, habitual behaviors) determinants of energy balance-related parenting were identified through a needs assessment. In step 2, the behavioral outcomes were translated into performance objectives. To influence these objectives, in step 3, theory-based intervention methods were selected for each of the determinants. In step 4, the knowledge derived from the previous steps allowed for the development of the app-based program Samen Happie! through a process of continuous cocreation with parents and health professionals. In step 5, community health services were identified as potential adopters for the app. Finally, in step 6, 2 randomized controlled trials were designed to evaluate the process and effects of the app among Dutch parents of infants (trial 1) and preschoolers (trial 2). These trials were completed in November 2019 (trial 1) and February 2020 (trial 2).

CONCLUSIONS

The IMP allowed for the effective development of the app-based parenting program Samen Happie! to promote healthy energy balance-related parenting practices among parents of infants and preschoolers. Through the integration of theory, empirical evidence, and data from the target population, as well as the process of continued cocreation, the program specifically addresses parents with a lower SEP. This increases the potential of the program to prevent the development of obesity in early childhood among families with a lower SEP.

Association of infant diet with subsequent obesity at 2-5 years among children exposed to gestational diabetes: the SWIFT study

AIMS/HYPOTHESES

This longitudinal analysis evaluated the independent and joint associations of any breastfeeding (BF) or exclusive BF (EBF) and intake of sugar-sweetened beverages (SSBs) and 100% fruit juice from birth to 1 year with subsequent overweight and obesity among young children exposed to gestational diabetes (GDM).

METHODS

The analysis utilised prospectively collected data from participants enrolled in the Study of Women, Infant Feeding and Type 2 Diabetes after GDM (SWIFT); 1035 pregnant women (20-45 years) diagnosed with GDM, of whom 75% were of Black, Hispanic or Asian race and ethnicity. Mother-infant dyad characteristics and infant dietary intake were assessed via research protocols at in-person examinations, telephone interviews and monthly mailed surveys from birth to 1 year. Child weight, length and height were obtained from electronic health records at birth (2008-2011) and ages 2-5 years (2010-2016) to classify BMI percentile groups (n = 835).

RESULTS

Adequate BF (≥6 months), adequate EBF duration (≥6 months), and SSB and 100% fruit juice intake in the first year were independently associated with child obesity at ages 2-5 years (all p < 0.05). Compared with children with adequate EBF and no intake of SSB or 100% fruit juice, those with adequate EBF and intake of 100% fruit juice and/or SSBs had a four- to fivefold higher odds of obesity (aOR 4.2, 95% CI:1.6, 11.2 for 100% fruit juice; aOR 4.5, 95% CI:1.4, 8.5 for fruit juice or SSBs; and aOR 4.7, 95% CI:1.4, 15 for SSBs; all p < 0.01), while those with inadequate EBF (<6 months) and intake of 100% fruit juice and/or SSBs had a six- to 12-fold higher odds of obesity (aOR 6.4, 95% CI:2.4, 17.2 for fruit juice; aOR 6.6, 95% CI:2.7, 14.8 for fruit juice or SSBs; and aOR 12.2, 95% CI:4.3, 25 for SSBs; all p < 0.001). Compared with children with adequate BF and no intake of SSB or 100% fruit juice, those with adequate BF and intake of 100% fruit juice and/or SSBs had a threefold higher odds of obesity (aOR 3.1, 95% CI:1.1, 7.3 for fruit juice; aOR 3.3, 95% CI:1.3, 8.3 for fruit juice or SSBs; and aOR 3.4, 95% CI:1.3, 8.5 for SSBs; all p < 0.05), while those with inadequate BF (<6 months) and intake of 100% fruit juice and/or SSB were associated with five- to tenfold higher odds of obesity (aOR 4.8, 95% CI:2.3, 12.2 for fruit juice; aOR 6.0, 95% CI:2.5, 12.8 for fruit juice or SSBs; aOR 9.5, 95% CI:3.7, 15.1 for SSBs; all p < 0.05).

CONCLUSIONS/INTERPRETATION

This is the first study to prospectively evaluate the relation of BF or EBF duration and intake of SSB and 100% fruit juice during the first year of life with subsequent obesity in children exposed to GDM. Adequate BF or EBF combined with avoidance of SSB and 100% fruit juice during early infancy may ameliorate future child obesity in this high-risk population.

A Health-Literacy Intervention for Early Childhood Obesity Prevention: A Cluster-Randomized Controlled Trial

BACKGROUND AND OBJECTIVES

Children who become overweight by age 2 have greater risk of long-term obesity and health problems. The study aim was to assess the effectiveness of a primary care-based intervention on the prevalence of overweight at age 24 months.

METHODS

In a cluster-randomized trial, sites were randomly assigned to the Greenlight intervention or an attention-control arm. Across 4 pediatric residency clinics, we enrolled infant-caregiver dyads at the 2-month well-child visit. Inclusion criteria included parent English- or Spanish-speaking and birth weight ≥1500 g. Designed with health-literacy principles, the intervention included a parent toolkit at each well-child visit, augmented by provider training in clear-health communication. The primary outcome was proportion of children overweight (BMI ≥85th percentile) at age 24 months. Secondary outcomes included weight status (BMI z score).

RESULTS

A total of 459 intervention and 406 control dyads were enrolled. In total, 49% of all children were overweight at 24 months. Adjusted odds for overweight at 24 months (treatment versus control) was 1.02 (95% confidence interval [CI]: 0.63 to 1.64). Adjusted mean BMI z score differences (treatment minus control) were -0.04 (95% CI: -0.07 to -0.01), -0.09 (95% CI: -0.14 to -0.03), -0.19 (-0.33 to -0.05), -0.20 (-0.36 to -0.03), -0.16 (95% CI: -0.34 to 0.01), and 0.00 (95% CI -0.21 to 0.21) at 4, 6, 12, 15, 18, and 24 months, respectively.

CONCLUSIONS

The intervention resulted in less weight gain through age 18 months, which was not sustained through 24 months. Clinic-based interventions may be beneficial for early weight gain, but greater intervention intensity may be needed to maintain positive effects.

Association of single nucleotide polymorphisms with taste and food preferences of the Hungarian general and Roma populations

It is reasonable to suppose that poor diet underlies the unfavorable health status of the Roma population of Europe. Previously in the framework of a complex health survey, fruit and vegetable consumption, quantity of sugar added, salting frequency; bitter, salty, sweet and fat taste preferences were evaluated of Hungarian (HG, n = 410) and Roma (HR, n = 387) populations. In the present study the associations of taste and food preferences with TAS1R3, CD36, SCNN1B, TRPV1, TAS2R38, TAS2R19 and CA6 polymorphisms were tested in the same samples. Genotype frequencies did not differ significantly between the two populations. Although we initially observed associations between certain genetic polymorphisms and taste and food preferences in our study samples, none of the p values remained significant after the multiple test correction. However, some of our results could be considered promising (0.05<corrected p < 0.20), which showed potential ethnicity-specific effects (CA6 rs2274333 with salty taste and raw kohlrabi preference, CD36 rs1527483 with fat taste preference, TAS2R19 rs10772420 with grapefruit preference, and TAS2R38 rs713598 with quantity of sugar added). Our results may suggest that genetics may mediate food preferences, and individuals with different ethnic background may require personalized interventions to modify diet. Further investigations with greater sample sizes are essential to explore the effect of these genetic variants on taste and food preferences.

A qualitative study of cognitive, behavioral, and environmental influences on Hispanic mothers' early childhood feeding practices

Young children's lifestyle behaviors are largely shaped by their parents. There are socioeconomic risk factors particular to Hispanic populations that influence the way parents feed their children. As obesity continues to be a public health issue with substantial inequities across race and ethnicity, it is critical to understand Hispanic parents' food choices and feeding practices. The objective of this qualitative study is to identify the behavioral, environmental, and cognitive factors that influence the parental food choices and feeding behaviors of Hispanic mothers of children ages 0-5 years. Snowball sampling was used to recruit participants from the community (n = 30) who were 1) female; 2) Hispanic; 3) over the age of 18; and 4) a mother to child(ren) between the ages zero and five. Each interview consisted of a brief demographic survey and a set of open-ended questions based on Social Cognitive Theory constructs. A thematic analysis using a combined deductive and inductive approach was used to analyze transcriptions. Results indicated that mothers' attitudes around breastfeeding were connected with their challenges, while their attitudes around solid foods were expressed in their feeding strategies. Mothers used strategies of modeling, repeated exposure, and practices of "sneaking" in healthy foods and bribing to promote healthy eating. Mothers were most likely to seek out information from (1) pediatricians, (2) female family members, and (3) the internet. Hispanic mothers actively seek out information from many different sources that impact how they feed their young children. Understanding their trusted sources and how it influences the SCT constructs is an important step in preventing early childhood obesity.

Racial-Ethnic Disparities in Obesity and Biological, Behavioral, and Sociocultural Influences in the United States: A Systematic Review

For a comprehensive understanding of high-level obesity in the USA, we studied the trends of obesity prevalence since 2007, and related biological, behavioral, and sociocultural factors in obesity racial/ethnic disparities. We searched PubMed, Embase, and national data archives for the studies using national survey data and published in English from January 1, 2007 to September 11, 2020. Forty-seven studies met the inclusion criteria and were systematically reviewed. After a short leveling-off during 2009-2012, the US national prevalence of obesity has steadily increased. Although women had higher racial/ethnic disparities in obesity and severe obesity than men, it decreased due to the significant drop in non-Hispanic black (NHB) women in the last 10 y. However, obesity and severe obesity prevalence increased in Mexican-American (MA) men, MA boys, and MA girls and became similar to or surpassing NHB groups. Substantial racial/ethnic disparities remained in the past decade. Even at the same level of BMI, MAs and non-Hispanic Asians had a higher percent of body fat and metabolic syndrome than other ethnic/racial groups. NHB's cultural preference for a large body significantly associated weight misperception and lower weight control practices. In addition to socioeconomic status, health behaviors, neighborhood environments, and early childhood health factors explained substantial racial/ethnic differences in obesity. Differences in biological, behavioral, and sociocultural characteristics should be considered in future public health intervention efforts to combat obesity in the USA.
