Description
This body of research sought to explore relationships between parenting practices, physical activity resources, and Hispanic children’s physical activity. Guided by the Family Ecological Model (FEM) and the Ecological Model of Physical Activity (EMPA) this study examined the influence of parents on children’s physical activity through an integrative review. A cross sectional study was conducted to investigate potential relationships between parental perception safety at school, gender, and children’s physical activity. A cross sectional study was also utilized to examine potential correlations between parenting practices, physical activity resources, and children’s physical activity. Parental role modeling of physical activity and parental support for physical activity emerged as parenting practices that have considerable potential to impact children’s physical activity. Gender differences among children’s physical activity were also a key finding of this study with boys participating in more physical activity than boys. While quality of physical activity resources did not have significant associations with parenting practices or children’s physical activity, more research is needed to determine how resources for physical activity may impact parenting practices, and children’s physical activity.

Description
This dissertation was guided by the Ecological Model of Physical Activity and Ecological Model of Obesity and sought to determine the relationship between active transportation (AT), physical activity, and cardiometabolic health among adults and ethnic minority women. Chapter 2 presents an investigation into the relationship between walking for AT and cardiometabolic health among adults through systematic review. Chapter 3 presents an exploration of the cross-sectional relationships of AT and moderate-to-vigorous physical activity (MVPA) with cardiometabolic health among African American (AA) and Hispanic/Latina (HL) women from Texas. Chapter 4 presents an investigation into the cross-sectional relationship of AT on cardiometabolic health and physical activity among primarily HL women.
In Chapter 2, walking for AT was found to be related to smaller waist circumference, lower blood pressure, and lower prevalence of abdominal obesity and hypertension, and that differences may exist based on sex. Walking for AT was not clearly defined, and criteria used to determine the presence of cardiometabolic outcomes were inconsistent. No significant relationships between AT and cardiometabolic health were found in Chapter 3 or 4; however, AT users had slightly better cardiometabolic health. AT users had significantly higher levels of self-reported total physical activity compared to those who did not use AT in Chapter 3. Furthermore, a significant relationship was found between MVPA and diastolic blood pressure. Associations differed by ethnicity, with MVPA being inversely related to body fat in both AA and HL women, but to body mass index only in AA women. AT users were found to be seven times more likely to meet 2018 national MVPA recommendations than non-AT users in Chapter 4. Across all studies, measures of AT were subjective and of low quality, potentially limiting the ability to detect significant findings.
High quality randomized controlled studies should be conducted using clearly defined, objective measures of AT, and analyzed based on sex and race/ethnicity. Clinicians should recommend AT use to promote meeting MVPA recommendations where appropriate, potentially resulting in improved cardiometabolic health. Policymakers should advocate for changes to the built environment to encourage AT use and MVPA to improve public health.

Description
Food insecurity and childhood obesity are both major public health concerns in the United States of America. Research has not found a definite relationship between childhood obesity and food insecurity to date, with conflicting results being found due to differences in sample sizes and protocol for measuring key variables. Preschoolers (children aged 2-5 years) are a population of particular interest as there tends to be improved health behaviors and greater adaptability to change at this period of growth and development. This study aims to evaluate if there is a relationship between food insecurity and childhood obesity with diet quality as a mediator among preschoolers in the Phoenix area. A secondary data analysis from participants (n=154) from the SAGE (Sustainability via Active Garden Education) research project was used to evaluate food insecurity status, diet quality components (kcal, saturated fat, added sugars, and servings of juice, fruits, and vegetables), and anthropometrics (waist circumference and BMI percentile). No significant associations between food insecurity status, diet quality components, and anthropometric data were found. There was an increased rate of food insecurity and childhood overweight/obesity in this sample compared to state and national averages. Further research of high quality is necessary to determine whether a relationship exists between childhood obesity and food insecurity exists and in what context. Additionally, practice and policy will need to be implemented to decrease rates of food insecurity and childhood obesity among Phoenix preschoolers.
