Diet Quality And Micronutrient Intake In Long-Term Weight Loss Maintainers, Rebecca W. Pascual

Master's Theses

Objective: This study’s purpose was to examine dietary quality, macronutrient intake, and micronutrient adequacy among long term weight loss maintainers (WLM) in a commercial weight management program.

Methods: Participants were 1,207 WLM in WW (formerly Weight Watchers) who had maintained a 9.1 kg or greater weight loss (29.7 kg on average) for 3.4 years, and had an average BMI of 28.3 kg/m². A control group of weight stable adults with obesity (Controls; N=102) had a BMI of 41.1 kg/m² and 2.3 kg or less weight change over the previous five years.

Results: WLM vs. …

More Rapid Increase In Bmi From Age 5–15 Is Associated With Elevated Weight Status At Age 24 Among Non-Hispanic White Females, Katherine N. Balantekin, Emily E. Hohman, Elizabeth L. Adams, Michele E. Marini, Alison K. Ventura, Leann L. Birch, Jennifer S. Savage

Kinesiology and Public Health

Background: A rapidly increasing BMI trajectory throughout childhood is associated with negative health outcomes in adulthood such as obesity, cardiovascular disease, and diabetes. The purpose of the current study was to assess whether BMI trajectories from age 5–15 predicted changes in weight and BMI from adolescence to adulthood, and dieting-related behaviors in young adulthood.

Methods: Non-Hispanic White female participants from Early Dieting in Girls (n=182), a longitudinal cohort study, were followed from age 5 to 15 and completed a follow-up survey at age 24. Participants were classified by age 5–15 BMI trajectory groups: UPC, accelerated weight gain from age …

Prevalence And Correlates Of Overweight And Obesity Among Preschool-Aged Children In San Luis Obispo County, 2006-2014, Kristine Z. Jankovitz, Alison K. Ventura, Trevor M. Curry, Victoria B. Howarth, Caitlin C. Moran, Robin M. Mertens, Leland A. Bailey, Kristen Thompson, Karen Mcgaughey

Kinesiology and Public Health

Background and Purpose: National prevalence of overweight and obesity (OW/OB) among children remains high; surveillance of OW/OB at state- and local-levels is needed. This study determines the prevalence and sociodemographic predictors of OW/OB among preschool-age children in San Luis Obispo (SLO) County.

Methods: Cross-sectional convenience samples of Head Start, California State, and private preschools were surveyed in 2006 (n=482), 2009/10 (n=559), and 2014 (n=442). At all waves, preschool children aged 3-5 years were measured for height and weight using standardized stadiometer and digital scale protocols. In 2014, parents completed a demographics questionnaire.

Results: Children assessed in 2009/10 and 2014 were …

Does Breastfeeding Shape Food Preferences? Links To Obesity, Alison K. Ventura

Kinesiology and Public Health

The first 2 years of life have been recognized as a critical window for obesity prevention efforts. This period is characterized by rapid growth and development and, in a relatively short period of time, a child transitions from a purely milk-based diet to a more varied solid-food diet. Much learning about food and eating occurs during this critical window, and it is well-documented that early feeding and dietary exposures predict later food preferences, eating behaviors, and dietary patterns. The focus of this review will be on the earliest feeding experiences - breast- and formula-feeding - and the unique role of …

An Examination Of An Environmental Change In Beverages Available To High School Students In Santa Maria, California On Their Consumption Behavior, Susan Eileen Klucker

Master's Theses

Hypothesis: "By an environmental change in high school vending machines, making water available, students will choose water over the sugar sweetened sodas."

This document highlights a case study analysis of vendor-provided refill data for forty-five beverage vending machines at two campus sites in one high school district in 2003 and 2004. The innovative study and publicized negotiated soda contract of a 50:50 (healthy to unhealthy) beverage ratio stipulation became the “Win-Win-WEAN” compromise, in which exposure to healthier beverage options for students might prove to provide the same income opportunity for the school district.

An overview of the political …

Maternal Acculturation Levels And Their Effect On Children's Food Intake, Maternal Perceptions Of Body Size And Maternal Stress, Tracie A. Chavoor

Master's Theses

In the U.S., obesity has hit alarming rates and affects Hispanic children disproportionately. Acculturation, the shift from one culture’s values, beliefs and practices to those of a new culture, may have both negative and positive health effects on immigrants. The objectives of this study were to determine the association between the level of acculturation (low acculturation or high acculturation) of low-income Latina mothers and the foods consumed by their children (0 to 36 months old). The association between acculturation and maternal perceptions of infant and toddler body size, maternal perceptions of her own body size and maternal parenting stress were …

Pregnancy: A "Teachable Moment" For Weight Control And Obesity Prevention, Suzanne Phelan

Kinesiology and Public Health

Excessive gestational weight gain has been shown to relate to high-postpartum weight retention and the development of overweight and obesity later in life. Because many women are concerned about the health of their babies during pregnancy and are in frequent contact with their healthcare providers, pregnancy may be an especially powerful "teachable moment" for the promotion of healthy eating and physical activity behaviors among women. Initial research suggests that helping women gain the recommended amount during pregnancy through healthy eating and physical activity could make a major contribution to the prevention of postpartum weight retention. However, more randomized controlled trials …

Clinical Research In Diabetes And Urinary Incontinence: What We Know And Need To Know, Suzanne Phelan, Francine Grodstein, Jeanette S. Brown

Kinesiology and Public Health

Purpose: We discuss epidemiological and clinical trial research in women with urinary incontinence and diabetes, and provide directions for future research.
Materials and Methods: Published epidemiological and clinical trial literature examining diabetes and incontinence is presented.
Results: Multiple studies have now confirmed that the prevalence and incidence of incontinence is increased in women with type 2 diabetes. Emerging evidence also suggests higher incontinence rates in women with type 1 diabetes or prediabetes. Clinical trial research suggests that weight loss can decrease incontinence in women with prediabetes. An ongoing multicenter trial will examine the effects of weight loss on incontinence in …

Childhood Poverty And Abdominal Obesity In Adulthood: A Systematic Review, David González, Aydin Nazmi, Cesar G. Victoria

Food Science and Nutrition

Adverse socioeconomic conditions in childhood can have lasting effects on health, but evidence is lacking from prospective studies concerning the effects of early poverty on abdominal obesity in adulthood. Cross-sectional studies in adults from middle and high-income countries show that current socioeconomic status is inversely related to obesity in women, but the pattern in men is not consistent. A systematic review was undertaken to assess the influence of early socioeconomic status on waist circumference, hip circumference, and waist-hip ratio in adulthood. Thirteen relevant articles were located (five cross-sectional and eight cohort), including only one from a middle-income country and the …

The National Weight Control Registry: Is It Useful In Helping Deal With Our Obesity Epidemic?, James O. Hill, Holly Wyatt, Suzanne Phelan, Rena Wing

Kinesiology and Public Health

The National Weight Control Registry (NWCR) consists of over 4800 individuals who have been successful in long-term weight loss maintenance. The purpose of establishing the NWCR was to identify the common characteristics of those who succeed in long-term weight loss maintenance. We found very little similarity in how these individuals lost weight but some common behaviors in how they are keeping their weight off. To maintain their weight loss NWCR participants report eating a relatively low-fat diet, eating breakfast almost every day, weighing themselves regularly, and engaging in high levels (about 1 hour/day) of physical activity. Because this is not …

Combining Behavioral And Pharmacological Treatments For Obesity, Suzanne Phelan, Thomas A. Wadden

Kinesiology and Public Health

Weight-loss medications are currently recommended for use only as an adjunct to diet, exercise, and behavior modification. Little, however, is known about the benefits of combining behavioral and pharmacological therapies or about the mechanisms that would make these combined approaches more effective than either used alone. This article reviews the effects of adding pharmacotherapy (i.e., principally sibutramine and orlistat) to a modest program of lifestyle modification. Studies revealed that the addition of medication typically improved short- and long-term weight loss compared with lifestyle modification alone. The best results, however, were obtained when medications were combined with an intensive, group program …
