Childhood obesity and comorbidities-related perspective and experience of parents from Black and Asian minority ethnicities in England: a qualitative study.

Background: Preventing childhood obesity and associated comorbidities is often hampered by disproportionate disparity in healthcare provision in minority ethnic populations. This study contextualized factors influencing childhood obesity and related comorbidity from the perspectives and experiences of parents of ethnic minority populations. Methods: Following ethical approval, families (n = 180) from ethnic minority populations in the Northeast of England were contacted through flyers, community social groups and online forum. Of the 180 families contacted, 22 expressed interests, of whom 12 parents were eligible to participate in the study, and one family dropped out due to time constraints. Therefore 11 parents from ethnic minority communities living with at least one child with obesity were interviewed. Each family was separately visited at home and took part in a semi-structured interview based on the study's qualitative, descriptive phenomenological design. Nine of the families had one child who was diagnosed with an obesity-related comorbidity (non-alcoholic fatty liver disease, musculoskeletal problems or respiratory disorder). Semi-structured interviews were standardized around parents' perspective and experience on how their children were impacted by obesity and comorbidities, healthcare preventative interventions including lifestyle physical activity and nutrition, and views on tackling obesity impact on their lives. All interviews were analyzed using qualitative thematic analysis. Results: Parents' perspectives revealed 11 themes centered around experience of living with a child with obesity, risks, and impact of obesity related Non-Communicable Diseases; and access to support, and barriers unique to minority ethnic groups. Parents revealed social disadvantages, fear of victimization by social services, perceptions on their cultural and religious traditions, and racial stigmatization related to their child's weight. Parents reported closer bonding with their children to protect them from the untoward consequences of overweight, and little awareness of healthcare obesity prevention programs. Work pressure, lack of time, absence of guidance from professionals were seen as barriers to healthy lifestyle, while support from friends and closer family bond in adopting healthy lifestyle behaviors were facilitators. However, there was little awareness or access to current healthcare obesity preventive offerings. Conclusion: Minority ethnic communities' perspective on childhood obesity prevention does not match the healthcare system preventative offerings. Community and family-oriented obesity preventative approaches, especially lifestyle interventions are needed beyond those administered by the primary healthcare system.

Cost-effectiveness of a primary care-based Healthy Weight Clinic compared with usual care.

OBJECTIVE: The objective of this study was to project the cost-effectiveness of implementing the Healthy Weight Clinic (HWC), a primary care-based intervention for 6- to 12-year-old children with overweight or obesity, at federally qualified health centers (FQHCs) nationally. METHODS: We estimated intervention costs from a health care sector and societal perspective and used BMI change estimates from the HWC trial. Our microsimulation of national HWC implementation among all FQHCs from 2023 to 2032 estimated cost per child and per quality-adjusted life year (QALY) gained and projected impact on obesity prevalence by race and ethnicity. Probabilistic sensitivity analyses assessed uncertainty around estimates. RESULTS: National implementation is projected to reach 888,000 children over 10 years, with a mean intervention cost of $456 (95% uncertainty interval [UI]: $409-$506) per child to the health care sector and $211 (95% UI: $175-$251) to families (e.g., time participating). Assuming effect maintenance, national implementation could result in 2070 (95% UI: 859-3220) QALYs gained and save $14.6 million (95% UI: $5.6-$23.5 million) in health care costs over 10 years, yielding a net cost of $278,000 (95% CI: $177,000-$679,000) per QALY gained. We project greater reductions in obesity prevalence among Hispanic/Latino and Black versus White populations. CONCLUSIONS: The HWC is relatively low-cost per child and projected to reduce obesity disparities if implemented nationally in FQHCs.

Assessing the acceptability of a culturally adapted group-based pediatric intervention, Kokajjiriri, for Marshallese mothers and infants to improve nutrition and prevent childhood obesity.

BACKGROUND: Marshallese Pacific Islanders experience higher rates of obesity than other racial and/or ethnic communities. Despite the obesity rates experienced in this community, there are currently no childhood obesity prevention interventions designed for Marshallese Pacific Islanders in the United States. The purpose of this study is to assess the acceptability and feasibility of a culturally adapted group-based pediatric intervention, Kokajjiriri, with Marshallese mothers to improve nutrition and reduce childhood obesity. METHODS: A multi-methods design was used to culturally adapt the Kokajjiriri intervention for Marshallese mothers in Arkansas (n = 17). In phase one, we conducted 24-h dietary recalls with 20 Marshallese mothers to inform the cultural adaptation of the group-based pediatric intervention, and then in phase two, we culturally adapted and piloted three sessions of the intervention to determine the acceptability and feasibility of the intervention. RESULTS: Participants found the adapted intervention to be acceptable and feasible, found the location to be convenient and found the facilitator to be knowledgeable. Four themes emerged from the qualitative data: (1) Lactation Support; (2) Introducing Healthy Solids; (3) Rice Portion Control; and (4) Finding Resources. CONCLUSIONS: This is the first study to assess the acceptability and feasibility of a culturally adapted group-based pediatric intervention, Kokajjiriri, with Marshallese mothers to improve nutrition and reduce childhood obesity. The results from this culturally adapted group-based pediatric intervention, Kokajjiriri, will be used to inform future adaptations and implementation of the full intervention for Marshallese women and children.

Childhood Obesity and Its Comorbidities in High-Risk Minority Populations: Prevalence, Prevention and Lifestyle Intervention Guidelines.

The prevalence of childhood obesity and its associated comorbidities is a growing global health problem that disproportionately affects populations in low- and middle-income countries (LMICs) and minority ethnicities in high-income countries (HICs). The increased childhood obesity disparities among populations reflect two concerns: one is HICs' ineffective intervention approaches in terms of lifestyle, nutrition and physical activity in minority populations, and the second is the virtually non-existent lifestyle obesity interventions in LMICs. This article provides guidelines on childhood obesity and its comorbidities in high-risk minority populations based on understanding the prevalence and effectiveness of preventative lifestyle interventions. First, we highlight how inadequate obesity screening by body mass index (BMI) can be resolved by using objective adiposity fat percentage measurements alongside anthropometric and physiological components, including lean tissue and bone density. National healthcare childhood obesity prevention initiatives should embed obesity cut-off points for minority ethnicities, especially Asian and South Asian ethnicities within UK and USA populations, whose obesity-related metabolic risks are often underestimated. Secondly, lifestyle interventions are underutilised in children and adolescents with obesity and its comorbidities, especially in minority ethnicity population groups. The overwhelming evidence on lifestyle interventions involving children with obesity comorbidities from ethnic minority populations shows that personalised physical activity and nutrition interventions are successful in reversing obesity and its secondary cardiometabolic disease risks, including those related to cardiorespiratory capacity, blood pressure and glucose/insulin levels. Interventions combining cultural contextualisation and better engagement with families are the most effective in high-risk paediatric minority populations but are non-uniform amongst different minority communities. A sustained preventative health impact can be achieved through the involvement of the community, with stakeholders comprising healthcare professionals, nutritionists, exercise science specialists and policy makers. Our guidelines for obesity assessment and primary and secondary prevention of childhood obesity and associated comorbidities in minority populations are fundamental to reducing global and local health disparities and improving quality of life.

Alpha Diversity Indices as Indicators of the Variability of Gut Microbiota in Obese Adolescents of Different Ethnicities.

We compared alpha diversity indices of the intestinal microbiota in adolescents with obesity and normal body weight, taking into account their ethnicity. Intestinal biocenosis was studied by metasequencing of amplicon libraries of V3-V4 fragments of the 16S rRNA gene. The alpha diversity of the microbiota was assessed using classical and alternative indices. Statistically significant differences in intestinal microbiota were observed between Russians with obesity and Buryats with normal body weight, as well as between Russians with obesity and Buryats with obesity when assessing the Shannon-Weaver, Chao1 indices, Faith phylogenetic diversity index, ACE, Fisher, Gini coefficient, Margalef, and Menkhinik indices. It was shown that alpha diversity indices can be used to assess significance of differences and variability of the intestinal microbiota in multifactorial diseases such as obesity in adolescents; however, the scope of application of the criteria should be considered.

Associations between Adolescent Preoperative Mental Health, Psychosocial Factors, and Body Mass Index.

BACKGROUND: There is little research on adolescent bariatric surgery and mental health (depression, anxiety, etc.) with racial/ethnic minority adolescents. The objective of this study is to determine associations between adolescents' preoperative reports of depression, anxiety, and self-esteem and caregiver's' reports of the caregiver-adolescent relationship and interpersonal relationships with adolescents' BMI and differences based on race/ethnicity. METHOD: Adolescents (ages 12-21) who underwent metabolic and bariatric surgery from June 2020 to November 2022 had their responses to specific items on the BASC-3 (anxiety, depression, and self-esteem) analyzed for associations with their body mass index (BMI) and with caregiver responses to the BASC-3 for adolescents' interpersonal skills and relationship with caregiver. Demographic differences on the BASC-3 were assessed. Pearson's correlations, independent t-tests, and ANOVA were used. RESULTS: Caregivers who had higher t-scores for relationship with their adolescents had adolescents who had lower depression t-scores, lower anxiety t-scores, and higher self-esteem t-scores. Parents who had higher t-scores for their adolescents' interpersonal relations had adolescents who had lower depression t-scores, lower anxiety t-scores, and higher self-esteem t-scores. White adolescents had higher depression t-scores than Black and Hispanic adolescents. Black and Hispanic adolescents had higher self-esteem t-scores compared to White adolescents. DISCUSSION: Some of the findings within the study regarding adolescents' race and ethnicity and mental health are not consistent with prior research, affirming the need for additional research of these sub-populations.

The Tip of the Iceberg: Genotype of Puerto Rican Pediatric Obesity.

Childhood obesity is a significant public health concern, particularly among Hispanic populations. This study aimed to elucidate the genetic predisposition to obesity in Puerto Rican children of Hispanic descent, addressing a notable gap in existing research. A cohort of 103 children with obesity and hyperphagia underwent genetic screening for rare obesity-related variants. Clinical assessments and family history evaluations were conducted to characterize the demographic and clinical characteristics of the cohort. Genetic testing revealed a high prevalence of variants, with 73% of subjects having at least one reported variant. Pathogenic variants, predominantly associated with obesity-related ciliopathies, were identified in 7% of cases. Additionally, 90% of cases had variants of uncertain significance, highlighting the complexity of genetic contributions to obesity. This study emphasizes the critical need for further investigation into the genetic foundations of obesity, particularly within Hispanic communities. The findings emphasize the importance of early medical evaluation, vigilant monitoring for hyperphagia onset, and targeted interventions tailored to the unique genetic landscape of Puerto Rican children. This research provides a foundational framework for future studies to mitigate the impact of genetic obesity within this population.

Acculturation and Health Status in the Children's Healthy Living Program in the Pacific Region.

Acculturation/enculturation has been found to impact childhood health and obesity status. The objective of this study is to use cross-sectional data to examine the association between proxies of adult/caregiver acculturation/enculturation and child health status (Body Mass Index [BMI], waist circumference [WC], and acanthosis nigricans [AN]) in the U.S.-Affiliated Pacific Islands (USAPI), Alaska, and Hawai'i. Study participants were from the Children's Healthy Living (CHL) Program, an environmental intervention trial and obesity prevalence survey. Anthropometric data from 2-8 year olds and parent/caregiver questionnaires were used in this analysis. The results of this study (n = 4121) saw that those parents/caregivers who identified as traditional had children who were protected against overweight/obesity (OWOB) status and WC > 75th percentile (compared to the integrated culture identity) when adjusted for significant variables from the descriptive analysis. AN did not have a significant association with cultural classification. Future interventions in the USAPI, Alaska, and Hawai'i may want to focus efforts on parents/caregivers who associated with an integrated cultural group as an opportunity to improve health and reduce child OWOB prevalence.

BMI Growth Profiles Among Black Children from Immigrant and US-Born Families.

A large body of research has documented racial/ethnic disparities in childhood obesity in the United States (US) but less work has sought to understand differences within racial groups. Longitudinal studies are needed to describe BMI trajectories across development, particularly for Black children from immigrant families who have been underrepresented in childhood obesity research. The current study utilizes BMI data collected longitudinally from ages 5 to 8 years and growth mixture modeling to (1) identify and visualize growth patterns among Black children from primarily Caribbean immigrant families, and (2) to compare these patterns to growth trajectories among Black children from US-born families. First, we identified four classes or trajectories of growth for Black children from immigrant families. The largest trajectory (70% of the sample) maintained non-overweight throughout the study period. A second trajectory developed overweight by age 8 (25%). Two small trajectory groups demonstrated high rates of moderate and severe obesity-i.e., specifically, a trajectory of accelerated weight gain ending in moderate/severe obesity (3%), and a trajectory of early severe obesity with BMI decreasing slightly with age (2%). We identified a very similar four class/trajectory model among Black children from US-born families, and compared the model to the one for children from immigrant families using multi-group growth mixture modeling. We found that the patterns of growth did not differ significantly between the populations, with two notable exceptions. Among Black children from immigrant families, ∼ 5% were classified into the two heavier BMI trajectories, compared to ∼ 11% of children from US-born families. Additionally, among children with an accelerated weight gain trajectory, children from immigrant families had lower BMIs on average at each time point than children from US-born families. These findings describe the multiple trajectories of weight gain among Black children from immigrant families and demonstrate that although these trajectories are largely similar to those of Black children from US-born families, the differences provide some evidence for lower obesity risk among Black children from immigrant families compared to Black children from US-born families. As this study is the first to describe BMI trajectories for Black children from immigrant families across early and middle childhood, future work is needed to replicate these results and to explore differences in heavier weight trajectories between children from immigrant and US-born families.

Alanine aminotransferase elevation varies by ethnicity among Asian and Pacific Islander children with overweight or obesity.

BACKGROUND: Limited research on alanine aminotransferase (ALT) screening for metabolic dysfunction-associated steatotic liver disease (MASLD) among US Asian/Pacific Islander (PI) children necessitates investigation in this heterogeneous population. OBJECTIVE: Examine ALT elevation among Asian/PI children with overweight or obesity. METHODS: Elevated ALT prevalence (clinical threshold) and association with body mass index ≥85th percentile were compared among 18 402 Asian/PI and 25 376 non-Hispanic White (NHW) children aged 9-17 years using logistic regression. RESULTS: ALT elevation was more prevalent among Asian/PI (vs. NHW) males with overweight (4.0% vs. 2.7%), moderate (7.8% vs. 5.3%) and severe obesity (16.6% vs. 11.5%), and females with moderate (5.1% vs. 3.0%) and severe obesity (10.2% vs. 5.2%). Adjusted odds of elevated ALT were 1.6-fold and ~2-fold higher for Asian/PI (vs. NHW) males and females (with obesity), respectively. Filipino, Chinese and Southeast Asian males had 1.7-2.1-fold higher odds, but Native Hawaiian/PI (NHPI) and South Asian males did not significantly differ (vs. NHW). Filipina and Chinese females with obesity had >2-fold higher odds, Southeast and South Asian females did not differ and NHPI findings were mixed (vs. NHW). CONCLUSION: High elevated ALT prevalence among Asian/PI children with overweight and obesity emphasizes the need for MASLD risk assessment and examination of ethnic subgroups.

Projected impact of anti-obesity pharmacotherapy use on racial and ethnic disparities in adolescent obesity.

BACKGROUND: Paediatric obesity disproportionately impacts individuals from minoritized racial and ethnic backgrounds. Recent guidelines support use of anti-obesity pharmacotherapy for adolescents with obesity, but the potential impact on disparities in obesity prevalence has not been evaluated. OBJECTIVES: To model changes in obesity prevalence with increasing utilization of anti-obesity pharmacotherapy among adolescents. METHODS: Data representative of American adolescents ages 12-17 years were obtained from the National Health and Nutrition Examination Survey, cycles 2011 through pre-pandemic 2020. A body mass index (BMI) reduction of 16.7% was applied to each participant based on clinical trial results of weekly subcutaneous semaglutide 2.4 mg among adolescents. Utilization disparities were based on utilization of the same medication class among adults. Obesity prevalence was calculated assuming utilization of 10%-100%, stratified by race and ethnicity. RESULTS: Among 4442 adolescents representing 26 247 384 American adolescents, projected overall obesity prevalence decreased from 22.2% to 8.4% with 100% utilization. However, disparities increased relative to Non-Hispanic White youth, with prevalence among Non-Hispanic Black and Mexican American youth ranging from 40%-60% higher to 90%-120% higher, respectively. CONCLUSIONS: Increasing utilization of anti-obesity pharmacotherapy may widen relative disparities in obesity, particularly if utilization is unequal. Advocacy for equitable access is needed to minimize worsening of obesity-related disparities.

Randomized-controlled trial of a whole-family obesity prevention and treatment intervention designed for low-income Hispanic families: HeLP the healthy living program.

BACKGROUND: Low-income Hispanic families face marked disparities in obesity, but interventions for obesity prevention and treatment have rarely been designed with this population as a focus. Hispanic culture is characterized by Familism, a value that prioritizes familial respect, cooperation, and togetherness. We describe the rationale and design of a trial of the Healthy Living Program (HeLP), a bilingual whole-family behavioral obesity prevention and treatment intervention designed around the value Familism and addressing food insecurity. METHODS/DESIGN: This two-group randomized comparative effectiveness trial will compare the effects of HeLP versus a primary care counseling intervention (Recommended Treatment of Obesity in Primary Care, or RTOP) on decreasing body mass index (BMI; kg/m2) in Hispanic children 2-16 years of age with obesity and preventing BMI increase among siblings without obesity. 164 families per arm will be recruited from primary care practices. Families randomized to HeLP will participate in 12 two-hour sessions, followed by booster sessions. HeLP sessions include family meals and instruction in parenting skills, nutrition, culinary skills, fitness, and mindfulness delivered at community recreation centers by bilingual health educators and athletic trainers. Families randomized to RTOP will be offered individual visits in primary care every 3 months throughout the 18-month follow-up period. Secondary outcomes include changes to objectively measured child fitness, the home environment related to nutrition, physical activity, and media usage, food insecurity, child eating behaviors, quality of life, parent BMI and waist circumference, and implementation outcomes. DISCUSSION: This protocol paper describes the rationale and planned methods for the comparative effectiveness trial. TRIAL REGISTRATION: Clinicaltrials.gov Identifier NCT05041855 (6/13/2023).

Modeling BMI z score lability during childhood as a function of child temperament and genetic risk for obesity.

OBJECTIVE: This study aimed to examine whether child genetic risk for obesity and temperament (i.e., negative affectivity, effortful control) accounted for stability versus lability in children's weight status (BMI z score) over time. METHODS: A total of 561 adopted children (42% female; 56% Caucasian, 13% African American, 11% Latino, and 20% other) and their birth and adoptive parents were followed from birth to age 9 years. The multilevel location-scale model was used to examine whether child genetic risk for obesity and temperament were related to differences in level and lability in child BMI z scores over time. RESULTS: For the full sample, higher levels of child negative affectivity were associated with greater BMI z score lability, whereas higher levels of effortful control and children's mean-level BMI z scores were related to less lability across childhood. Additional analyses examined associations within groups of children with healthy versus overweight/obesity weight statuses. Within the healthy weight status group only, better effortful control was associated with more stable BMI z scores, whereas genetic risk for higher BMI was associated with more labile BMI z scores. CONCLUSIONS: These findings provide insights into factors that can be harnessed to redirect unhealthy trajectories as well as factors that may challenge redirection or maintain a healthy trajectory.

Diet Quality among Pre-Adolescent African American Girls in a Randomized Controlled Obesity Prevention Intervention Trial.

Consuming an unhealthy diet increases health risks. This study assessed the impact of a culturally adapted behaviorally innovative obesity prevention intervention (The Butterfly Girls and the Quest for Founder's Rock) on diet quality in pre-adolescent non-Hispanic Black/African American girls. The RCT consisted of three groups (experimental, comparison, and waitlist control); block randomization allocated participants to each group. The two treatment groups varied in terms of whether or not they set goals. Data were collected at baseline (prior to receiving the intervention), post 1 (3 months post-baseline), and post 2 (6 months post-baseline). Two dietitian-assisted 24 h dietary recalls were collected at each timepoint. Healthy Eating Index 2015 (HEI-2015) was used to determine diet quality. A total of 361 families were recruited; 342 completed baseline data collection. No significant differences in overall HEI score or component scores were observed. To attain more equitable health outcomes, future efforts to promote dietary intake change among at-risk children should explore other behavior change procedures and employ more child-friendly dietary assessment methods.

Novel Differentially Methylated Regions Identified by Genome-Wide DNA Methylation Analyses Contribute to Racial Disparities in Childhood Obesity.

The magnitude of the childhood obesity epidemic and its effects on public health has accelerated the pursuit of practical preventative measures. Epigenetics is one subject that holds a lot of promise, despite being relatively new. The study of potentially heritable variations in gene expression that do not require modifications to the underlying DNA sequence is known as epigenetics. Here, we used Illumina MethylationEPIC BeadChip Array to identify differentially methylated regions in DNA isolated from saliva between normal weight (NW) and overweight/obese (OW/OB) children and between European American (EA) and African American (AA) children. A total of 3133 target IDs (associated with 2313 genes) were differentially methylated (p < 0.05) between NW and OW/OB children. In OW/OB children, 792 target IDs were hypermethylated and 2341 were hypomethylated compared to NW. Similarly, in the racial groups EA and AA, a total of 1239 target IDs corresponding to 739 genes were significantly differentially methylated in which 643 target IDs were hypermethylated and 596 were hypomethylated in the AA compared to EA participants. Along with this, the study identified novel genes that could contribute to the epigenetic regulation of childhood obesity.

American Indian Alaska Native (AIAN) adolescents and obesity: the influence of social determinants of health, mental health, and substance use.

OBJECTIVE: To explore the prevalence of obesity among American Indian and Alaska Native (AIAN) adolescents aged 12-19 years in association with social determinants of health (SDOH), and mental health and substance use disorders. METHODS: Guided by the World Health Organization's Social Determinants of Health Framework, we examined data from the Indian Health Service (IHS) Improving Health Care Delivery Data Project from Fiscal Year 2013, supplemented by county-level data from the U.S. Census and USDA. Our sample included 26,226 AIAN adolescents ages 12-19 years. We described obesity prevalence in relationship to SDOH and adolescents' mental health and substance use disorder status. We then fit a multivariable logit generalized linear mixed model to estimate the relationships after adjusting for other individual and county level characteristics. RESULTS: We observed a prevalence of 32.5% for obesity, 13.8% for mental health disorders, and 5.5% for substance use disorders. Females had lower odds of obesity than males (OR = 0.76, p < 0.001), which decreased with age. Having Medicaid coverage (OR = 1.09, p < 0.01), residing in a county with lower education attainment (OR = 1.17, p < 0.05), and residing in a county with higher rates of poverty (OR = 1.51, p < 0.001) were each associated with higher odds of obesity. Residing in a county with high access to a grocery store (OR = 0.73, p < 0.001) and residing in a county with a higher proportion of AIANs (OR = 0.83, p < 0.01) were each associated with lower odds of obesity. Those with mental health disorders had higher odds of obesity (OR = 1.26, p < 0.001); substance use disorders were associated with decreased odds of obesity (OR = 0.73, p < 0.001). CONCLUSIONS: Our findings inform future obesity prevention and treatment programs among AIAN youth; in particular, the need to consider mental health, substance use, and SDOH.

Scoping review protocol of multicomponent interventions to address cardiometabolic disease risk among Pacific Islander children.

INTRODUCTION: Multicomponent interventions can reduce cardiometabolic disease (CMD) risk factors in childhood; however, little synthesis of the literature has taken place in the Pacific region. Pacific Islanders experience a disproportionately high prevalence of CMD risk factors, yet interventions have been slow to reach many communities. We present this protocol for a scoping review to identify and summarize existing multicomponent interventions to address CMD risk in Pacific Islander children. MATERIALS AND METHODS: Eligible interventions will (1) address CMD risk factors (including but not limited to obesity, hyperglycemia, dyslipidemia, elevated blood pressure, and/or health behaviors) in 2-to-12-year-old Pacific Islander children, and (2) be multi-component (including at least two lifestyle/behavior change strategies to address CMD risk factors). To investigate existing interventions for adaptation and potential use in Pacific Islander communities, we will search Scopus, MEDLINE ALL (Ovid), EMBASE (Ovid), Yale-licensed Web of Science Core Collection, Cochrane Library, CINAHL (EBSCOhost), ProQuest Dissertations & Theses Global, Global Health (EBSCO), non-indexed Pacific journals, grey literature, government reports, and clinical trial registrations. The Joanna Briggs Institute Manual for Evidence Synthesis and the Preferred Reporting Items for Scoping Reviews will guide data extraction, evidence mapping, synthesis, and reporting of information including study population, intervention components, behavioral changes, health and implementation outcomes, theoretical frameworks, and evaluation measures. ETHICS AND DISSEMINATION: Formal ethical approval is not required. The dissemination strategy will include peer-reviewed journal publications and presentations. Synthesis of existing multicomponent interventions for Pacific Islander children will help to identify best practices that could be replicated, adapted, or combined.

Do Appetite Traits Mediate the Link Between Birth Weight and Later Child Weight in Low-Income Hispanic Families?

Background: Birth weight and appetite traits (ATs) are important early life determinants of child weight and obesity. Objectives: The aim of this study is to examine whether (1) birth weight-for-gestational age z-scores (BWGAzs) were associated with ATs at child age 2 years and (2) ATs mediated the link between BWGAzs and weight-for-age z-scores (WFAzs) at child ages 3 and 4 years among Hispanic children. Methods: We conducted a secondary longitudinal analysis of data from the Starting Early Program of low-income, Hispanic mother-child pairs. ATs were assessed using the Child Eating Behavior Questionnaire at age 2 years. Child birth weight was obtained from medical records. Birth weight, sex, and gestational age were used to generate BWGAzs with Fenton growth curves. WFAz was calculated based on the CDC 2000 growth charts. Regression and mediation analyses were used to explore associations between BWGAzs, ATs, and WFAzs. Results: Infants with higher BWGAzs had significantly lower Satiety Responsiveness (B = -0.10) and Food Fussiness (B = -0.13) scores at age 2 years and higher WFAzs at ages 3 (B = 0.44) and 4 (B = 0.34) years. Lower Satiety Responsiveness at age 2 years was associated with higher WFAzs at ages 3 (B = -0.11) and 4 (B = -0.34; all p < 0.01) years. Lower Satiety Responsiveness partially mediated the positive relationship between birth weight and child WFAzs at ages 3 and 4 years. Conclusions: Children with higher birth weight and lower Satiety Responsiveness scores may be at higher risk of developing obesity in childhood. Further research is needed to understand the mechanisms through which birth weight influences child appetite. Clinical Trial Registration: ClinicalTrials.gov: NCT01541761.

The effect of AGTR1, AGТ, LPL, ADRB2 gene polymorphisms on central obesity in adolescents of the Kazakh population.

BACKGROUND: Abdominal obesity, usually measured by waist circumference and waist-to-hip ratio, is more closely related to metabolic dysfunctions that are associated with cardiovascular diseases than general obesity, which is usually assessed by body mass index. The purpose of our study was to study the distribution of alleles and genotypes AGTR1, AGТ, LPL and ADRB2 among adolescents of the Kazakh population and to identify the relationship of these genes with predictors of obesity. METHODS: The study involved 184 adolescents aged 15-18 years of the Kazakh population. RESULTS: As a result of the study, it was revealed that the G allele of the rs328 polymorphism of the LPL gene reduces the risk of developing abdominal obesity compared to the C allele.The C/G genotype reduces the risk of developing abdominal obesity. We have identified among the studied adolescents of the Kazakh population an increase in the ratio of waist volume (WV) to hip volume (HV) among boys, which may in the future lead to obesity and cardiovascular diseases in general. CONCLUSION: It was also found that the G allele of the rs328 polymorphism of the LPL gene reduces the risk of abdominal obesity. Therefore, in addition to determining BMI, we recommend determining the ratio WV to HP. It was found that an increase in the ratio of WV/HV by 1 cm increases the chance of developing hypoapolipoproteinemia A1 (Tab. 4, Fig. 1, Ref. 23).

A Community Health Center Childhood Obesity Program for Latino Families from an Agricultural Community: Mental Health and Physical Activity Outcomes.

The purpose of this study was to evaluate the impact of an ongoing multidisciplinary childhood obesity intervention, within a federally qualified health center, on mental health and physical activity outcomes with Latino children from an agricultural community. The program was evaluated using attendance and parent-reports of child mental health and physical activity levels. Paired t-tests and chi squared tests were used to examine pre-post change in outcomes. There were 100 total participants. The mean age was 9.40 years, and the mean BMI percentile was 97.39. Significant post-intervention improvements were observed in mental health externalizing and internalizing problems (p <.0001) and in weekly physical activity frequency (p =.0131) and duration (p = .0280). Childhood obesity interventions should target mental health problems as well as obesity as the two are closely related. Community health centers may be ideal settings for interventions as they can facilitate access to needed services for high-risk populations.
