Emotional Eating In Adolescents With Obesity: Case Series, Paula Dayan

Electronic Theses, Projects, and Dissertations

Childhood obesity remains a significant public health concern, with substantial implications for physical and mental well-being. This thesis aims to explore the intricate relationship between emotional eating and obesity among adolescents, with a focus on identifying emotional triggers and assessing their psychological impact. Utilizing a cross-sectional study design at a university in southern California, data were collected from two adolescents aged 13-18 years. Through surveys and body composition measurements, participants' emotional barriers to weight loss and readiness for change were assessed. The findings underscore the presence of varying degrees of emotional hurdles among adolescents with obesity, including depression, frustration, and …

STEMPS Faculty Publications

Growing rates of childhood obesity globally create concern for individuals' health outcomes and demands on health systems. While many policy approaches focus on macro-level interventions, we examine how the type of stability of a family structure might provide opportunities for policy interventions at the micro level. We examine the association between family structure trajectories and childhood overweight and obesity across three Anglophone countries using an expanded set of eight family structure categories that capture biological relationships and instability, along with potential explanatory variables that might vary across family trajectories and provide opportunities for intervention, including access to resources, family stressors, …


How Does Parents’ Social Support Impact Children’S Health Practice? Examining A Mediating Role Of Health Knowledge, Paulin Tay Straughan, Chengwei Xu Dec 2023

How Does Parents’ Social Support Impact Children’S Health Practice? Examining A Mediating Role Of Health Knowledge, Paulin Tay Straughan, Chengwei Xu

Research Collection School of Social Sciences

Background: Family environmental factors play a vital role in shaping children’s health practices (e.g., obesity prevention). It is still unclear how parents’ social support affects children’s obesity-related health practices. The present study argues that whether parents’ social support positively associates with children’s obesity-related health practice depends on if it could promote parents’ obesity-related health knowledge. Thus, we hypothesize that health knowledge mediates the relationship between parents’ social support and children’s health practice regarding weight management. Methods: To test the hypothesis, we conducted a questionnaire survey and collected a nationally representative sample of 1488 household responses in Singapore. The survey included …


Translating A Pediatric Weight Management Intervention Into Medically Underserved Areas, Caitlin Golden May 2023

Translating A Pediatric Weight Management Intervention Into Medically Underserved Areas, Caitlin Golden

Theses & Dissertations

Despite substantial prevention and treatment efforts, childhood obesity remains a pressing public health concern. Disparities persist in obesity prevalence among children of lower socioeconomic status, racial and ethnic minority groups, and those residing in rural areas. The vast majority of efficacious pediatric weight management interventions (PWMIs) have been based in larger cities and urban areas delivered through inter-disciplinary teams in a hospital or medical center, and the degree to which these or other efficacious PWMIs have been translated to, and are feasible in, typical rural or micropolitan areas is unclear. This dissertation describes a dissemination strategy and a systematic approach …


Childhood Obesity In The United States, Emma Stohl May 2023

Childhood Obesity In The United States, Emma Stohl

Ballard Brief

Childhood obesity has been a problem in the United States for decades. The rate of childhood obesity has tripled since the 1970s. As of 2023, 1 in 5 children in the US are obese, with this number rising yearly. Childhood obesity is exacerbated by the lifestyle of children, where their attention is consumed by technology use at the expense of consuming nutritious foods and participating in physical activities. The lack of physical education in schools influences children’s health education and is partly responsible for childhood obesity. Genetics also play a role in childhood obesity depending on the characteristics of a …

Development And Piloting Of A Novel Evaluation Tool For Childhood Obesity Prevention Programs, Heather Norman-Burgdolf, Anne R. Lindsay, Kelly Webber, Julie C. Parker, Ingrid K. Richards Adams, Rafida Idris, Laura Hubbs-Tait, Karen Chapman-Novakofski

Journal of Human Sciences and Extension

Childhood obesity remains chronic and high in the U.S., driven by factors including poor dietary habits and lack of physical activity. Interventions that address multiple causal factors may be the most appropriate strategy to address rising childhood obesity rates. The Cooperative Extension Service offers programs across the country to address causal factors of childhood obesity, but few coordinated or concerted efforts have been made to determine overlap, reduce duplication, or identify best practices in programming. To fill this gap, the National Institute of Food and Agriculture Multistate Project W3005 Extension Workgroup sought to develop a novel tool to compare programs …

From Childhood Obesity Risk To Healthy Growth In The U.S.: A 10-Year Social Work Research & Policy Update, Brittany R. Schuler, Christian E. Vazquez, Nicole O'Reilly

Social Work Faculty Publications and Presentations

Childhood obesity is a major health issue and a prominent chronic health condition for children in the United States (U.S.), caused by a multitude of factors. Most existing models of childhood obesity prevention have not worked, yielding little to no effect on improving weight status or the proximal health behaviors most attributed to obesity risk: nutritional intake, physical activity, sedentary behaviors, and sleep. There is an urgent need for new approaches to prevent health disparities that are responsive to impacts of economic inequality on healthy child growth in marginalized populations. In this Short Commentary, a social justice update is …


Parents’ Knowledge, Attitudes, And Practices Of Childhood Obesity In Singapore, Paulin Tay Straughan, Chengwei Xu Dec 2022

Parents’ Knowledge, Attitudes, And Practices Of Childhood Obesity In Singapore, Paulin Tay Straughan, Chengwei Xu

Research Collection School of Social Sciences

The obesity pandemic is increasingly threatening Asian populations. This is especially so for children from higher-income countries, such as Singapore. Among the various driving factors of obesity, parents’ health knowledge, attitudes, and practices are underexplored. The present study uses a nationally representative sample of 1,491 responses from Singapore to investigate parental knowledge, attitudes, and practices (KAP) about childhood obesity. Latent class analysis (LCA) on parents’ responses to the KAP survey reveals four unique parenting patterns: the limited knowledge group, the group with negative attitudes, the best practice group, and the limited practice group. Children of families in the best practice …


How Does Parents' Social Support Impact Children's Health Practice? Examining A Mediating Role Of Health Knowledge, Paulin Tay Straughan, Chengwei Xu Jul 2022

How Does Parents' Social Support Impact Children's Health Practice? Examining A Mediating Role Of Health Knowledge, Paulin Tay Straughan, Chengwei Xu

Research Collection School of Social Sciences

Background: Many existing studies have found that social support and health knowledge positively affect an individual's health status. However, it is still unclear how parents’ social support and health knowledge influence their children’s obesity. The present study hypothesizes that parents’ health knowledge has a mediating effect on the relationship between social support and children’s health practice regarding weight management. Methods: To test the hypothesis, we conducted a questionnaire survey in Singapore and collected a nationally representative sample of 1488 household responses. Structural equation modeling (SEM) via Stata was used to examine the indirect effects of parents’ social support on children’s …


Encouraging Healthier Habits In Children, Krysta Hughes Apr 2022

Encouraging Healthier Habits In Children, Krysta Hughes

IPS/BAS 495 Undergraduate Capstone Projects

Childhood obesity rates in America are the highest they've ever been. In this research we are focused on encouraging healthier habits in children. The method used was an observational, cross-sectional online survey of 5 children and 4 parents. All of the children and parents wanted to pick healthier behaviors after reading my book. A Qualtrics survey was used to record each surveyor's response. Further research on this topic should include researching how many children have began to implement healthier habits and measure if the rate of obesity in children has been affected through yearly health visits.

Child Obesity Moderates The Association Between Poverty And Academic Achievement, Ashley W. Kranjac, Dinko Kranjac

Sociology Faculty Articles and Research

Childhood overweight and obesity are major public health problems in the United States. Children who experience poverty are 1.5 times more likely to suffer with overweight and 1.6 times more likely to have obesity. The extent to which overweight or obesity exacerbates the negative influence of socioeconomic inequality on child academic outcomes has not yet been examined. We estimated the effect of poverty on math and reading achievement trajectories using the Early Childhood Longitudinal Study (ECLS) Kindergarten class of 1998−1999 survey data and multilevel growth curve modeling techniques. Our findings indicate that the impact of obesity status is more pronounced …

Sensitray: An Integrated Measuring Device For Monitoring Children’S Mealtime Dietary Intake, Hunter S. Guru, Anthony D. Weng, Santosh Pitla, Dipti Dev

Department of Child, Youth, and Family Studies: Faculty Publications

Childhood nutrition establishes consumption norms that affect an individual’s health over the course of their lives. However, early nutrition interventions to establish such norms are uncommon owing to the various inefficiencies associated with current methods of measuring childhood nutrition. Here, we present an IoT measuring device, called the SensiTray, which accurately tracks mealtime intake in a child-friendly and cost-effective fashion. Principal technologies underlying the SensiTray (including mass-sensing technologies, microcontrollers) are identified and analyzed, along with other design choices. Operation of the SensiTray is explained with special attention given to SensiTray software peripherals and algorithms. Preliminary testing consisted of static and …

An Evaluation Of A Web-Based Tool To Improve Feeding Practices And The Home Environment Among Parents Of Low-Income Minority Preadolescents At-Risk For Childhood Obesity, Katrina F. Mateo

Dissertations and Theses

Background: Web-based/mHealth interventions may be an engaging approach to promote positive dietary-related behaviors among parents of youth at-risk for childhood obesity. Importantly, childhood obesity research highlights the role of parents as a key support mechanism in improving child dietary outcomes. Intervention INC is a childhood obesity intervention that comprises a unique, interactive web-based child nutrition comic aimed at improving dietary behaviors among urban Black/African American (AA) and Latino preadolescents, and also weekly online parent newsletters (with feeding tips, healthy printable recipes, links to coupons to support healthy eating/feeding and health-promoting local/community events, and access to the child nutrition comic) to …


Childhood Obesity In California: The Impact Of School Lunch Options And Physical Education Standards In Public Elementary Schools, Audrey Connell Jan 2020

Childhood Obesity In California: The Impact Of School Lunch Options And Physical Education Standards In Public Elementary Schools, Audrey Connell

Scripps Senior Theses

Obesity is a biosocial phenomenon in that it is shaped by both biological and social processes. On the biological level, excess body fat increases one’s risk of placing the body in a non-homeostatic state that can weaken the immune response. On the social level, social inequalities are linked to obesity in the United States where racial and ethnic minority communities with low education and high poverty rates bear the largest burden of obesity. In various institutions, multiple actors such as food marketers, public health officials, policy makers, and school administrators dictate the opportunities available to children for them to reach …


Racial Differences In Factors Influencing Childhood Overweight And Obesity In The Us, Brendan C. Ibe Jan 2020

Racial Differences In Factors Influencing Childhood Overweight And Obesity In The Us, Brendan C. Ibe

Electronic Theses and Dissertations

Background: Childhood overweight and obesity in the US has persisted as a serious public health concern despite efforts to address it. Children today are now estimated to live shorter life expectancy than their parents due to the consequences of childhood overweight and obesity. The earlier focus on healthy diets and an increase in physical activity have proved inadequate in reversing the trend. Using the social ecologic model (SEM), this study assessed the ecological and behavioral influences on childhood overweight and obesity among Non-Hispanic white, Non-Hispanic black, and Hispanic children. Methods: The study data were derived from the 2016 National Survey …


Food Preferences Among Children At Arcadia Elementary School, Laurel Lee Dec 2019

Food Preferences Among Children At Arcadia Elementary School, Laurel Lee

Community Based Research

My research, conducted from September through November of 2017, showed that the children preferred more processed foods and starches instead of healthier options such as fruits and vegetables, even when healthy options were available. According to the parents/caregivers surveyed, their children prefer to eat processed American meals. Parents/caregivers desired for their children to eat a variety of different foods including fruit, vegetables, proteins, and traditional Hispanic food. This study acknowledges that healthy meal options are available at schools, but there needs to be more research on how to best encourage students to take advantage of these nutritious choices in order …

The Shape Study : The Survey Of Health And The Perceived Environment Study., Colette Patrice Davis May 2019

The Shape Study : The Survey Of Health And The Perceived Environment Study., Colette Patrice Davis

Electronic Theses and Dissertations

Introduction: Few studies have considered how an individual’s perception of their built environment may be a risk factor for being overweight or obese. Adolescents may be particularly vulnerable in the context of “impoverished environments”, which they may perceive to be difficult, dangerous, resource deficient, and unaesthetic. This study aids in clarifying how the built environment influences the risk of obesity among adolescents residing in a neighborhood in Louisville, KY. Objective: The overall objective was to conduct a cross-sectional epidemiologic pilot study among adolescents aged 12-17 years residing in West Louisville, Kentucky to evaluate the association between perceptions of …


Maternal Work Hours And Childhood Obesity: Evidence Using Instrumental Variables Related To Sibling School Eligibility, Charles J. Courtemanche, Rusty Tchernis, Xilin Zhou Jan 2019

Maternal Work Hours And Childhood Obesity: Evidence Using Instrumental Variables Related To Sibling School Eligibility, Charles J. Courtemanche, Rusty Tchernis, Xilin Zhou

Economics Faculty Publications

This study exploits plausibly exogenous variation derived from the youngest sibling’s school eligibility to estimate the effects of maternal work on the weight outcomes of older children. We first show that mothers’ work hours increase gradually along both the extensive and intensive margins as the age of the youngest child rises, whereas mothers’ spouses’ work hours do not appear to be responsive. We develop an instrumental-variables model that shows that mothers’ work hours lead to larger increases in children’s body mass index z-scores and probabilities of being overweight/obese than those identified in previous studies. Subsample analyses find that the …

Farm Fresh Foods For Healthy Kids (F3hk): An Innovative Community Supported Agriculture Intervention To Prevent Childhood Obesity In Low-Income Families And Strengthen Local Agricultural Economies, Rebecca A. Seguin, Emily H. Morgan, Karla L. Hanson, Alice S. Ammerman, Stephanie B. Jilcott Pitts, Jane Kolodinsky, Marilyn Sitaker, Florence A. Becot, Leah M. Connor, Jennifer A. Garner, Jared T. Mcguirt

College of Agriculture and Life Sciences Faculty Publications

Background: Childhood obesity persists in the United States and is associated with serious health problems. Higher rates of obesity among children from disadvantaged households may be, in part, attributable to disparities in access to healthy foods such as fruits and vegetables. Community supported agriculture can improve access to and consumption of fresh produce, but the upfront payment structure, logistical barriers, and unfamiliarity with produce items may inhibit participation by low-income families. The aim of this project is to assess the impact of subsidized, or "cost-offset," community supported agriculture participation coupled with tailored nutrition education for low-income families with children. Methods/design: …


Childhood Obesity: Physiological And Psychological Implications And Ethical Responsibilities, Connie S. Lewis Jan 2017

Childhood Obesity: Physiological And Psychological Implications And Ethical Responsibilities, Connie S. Lewis

Journal of Health Ethics

Childhood obesity continues to be a health concern in the United States with physiological and psychological consequences. Research conducted in schools may address the physiological effects and exacerbate negative psychological effects, including weight bias and stigmatization. In the home, children are dependent on parents/caregivers to provide a healthy diet and exhibit a healthy lifestyle.The ethical theory, ethics of care, emphasizes dependence and interdependence on others, and ethical and moral responsibilities in the parent/child relationship. The assurance of ethical considerations involving children in research and parental provision for healthy dietary provision is of utmost importance. Any action or inaction that results …


"Getting Your Boots Dirty": Opportunities For Farm To School In The Southern San Joaquin Valley Of California, Ross Eskridge Jan 2017

"Getting Your Boots Dirty": Opportunities For Farm To School In The Southern San Joaquin Valley Of California, Ross Eskridge

Cal Poly Humboldt theses and projects

In the past twenty to thirty years, critics-both public and private-have scrutinized the national network of public school nutrition programs and the food they serve in cafeterias. Negative claims particularly voice concerns about the quality of foods available to students. School food items have been characterized as highly processed, lacking in nutritional value, and unappetizing in taste and appearance. Furthermore, industrialized, non-locally sourced public school food has been blamed for contributing to high rates of childhood obesity and associated health risks. In response to these claims, federal, state and local governments have pushed for changes in public school nutrition programs. …
