The Effects Of Alterations To Upper Limb Inertial Properties On Vertical Point-To-Point Movement, Adrian K. Hongo

Master's Theses

Purpose: Several studies have examined intralimb coordination between the shoulder and elbow joints during target-oriented movements. These studies have observed consistent patterns in coordination despite changes in movement variables such as speed, direction, and inertia. Researchers used intersegmental dynamics to quantitatively analyze these patterns between shoulder and elbow joints while systematically changing values of these movement variables. Some studies have examined central nervous system adaptations to inertial changes at the elbow and entire arm during a movement, but none have examined inertial changes to the upper limb. Methods: Five male and five female participants aged 27 to 39 years (mean …

Dairy Intake And 1,25-Dihydroxyvitamin D Levels In Men At High Risk For Prostate Cancer, Marilyn Tseng, Veda Giri, Deborah Watkins-Bruner, Edward Giovannucci

Kinesiology and Public Health

Objective Dairy food intake has been associated with prostate cancer in previous work, but the mechanism by which this occurs is unknown. Dairy calcium may suppress circulating levels of potentially cancer-protective 1,25-hydroxyvitamin D (1,25(OH)2D). We examined the associations of dairy, milk, calcium, and vitamin D intake with plasma 1,25(OH)2D levels among 296 men (194 black, 102 non-black) enrolled in a high risk program for prostate cancer from 10/96 to 10/07. Methods All participants completed diet and health history questionnaires and provided plasma samples, which were assessed for levels of 25-hydroxyvitamin D and 1,25(OH)2D. We used multivariate linear regression to examine …

Reproducibility Of Reported Nutrient Intake And Supplement Use During A Past Pregnancy: A Report From The Children’S Oncology Group, Jaclyn L.F. Bosco, Marilyn Tseng, Logan G. Spector, Andrew F. Olshan, Greta R. Bunin

Kinesiology and Public Health

Maternal diet and nutrition have been thought to play a role in many childhood conditions. Studies using food frequency questionnaires (FFQ) have reported associations with maternal diet, but these findings are difficult to interpret because the reliability and validity of the FFQs for diet during a past pregnancy are not known. We determined the reproducibility of reported diet and supplement use during a past pregnancy in a subset of mothers interviewed for a case–control study of maternal diet in relation to the risk of childhood brain tumours. Cases were Children’s Oncology Group patients, diagnosed at age code, race/ethnicity, and birth …

Dietary Patterns And Colon Cancer Risk In Whites And African Americans In The North Carolina Colon Cancer Study, Jessie A. Satia, Marilyn Tseng, Joseph A. Galanko, Christopher Martin, Robert S. Sandler

Kinesiology and Public Health

We examined associations of dietary patterns with colon cancer risk in African Americans and Whites from a case-control study in North Carolina. Incident colon cancer cases, 40 to 80 yr (n = 636), and matched controls (n = 1,042) were interviewed in person to elicit information on potential colon cancer risk factors. A validated food frequency questionnaire adapted to include regional foods captured diet over the year prior to diagnosis (cases) or interview date (controls). Three meaningful intake patterns were identified in both Whites and African Americans: “Western-Southern,” “fruit-vegetable,” and “metropolitan.” Compared to the Western-Southern pattern, the fruit-vegetable and metropolitan …

Becoming Physically Active After Bariatric Surgery Is Associated With Improved Weight Loss And Health-Related Quality Of Life, Dale S. Bond, Suzanne Phelan, Luke G. Wolfe, Ronald K. Evans, Jill G. Meador, John M. Kellum, James W. Maher, Rena R. Wing

Kinesiology and Public Health

The purpose of this study was to determine whether pre- to postoperative increases in physical activity (PA) are associated with weight loss and health-related quality of life (HRQoL) following bariatric surgery. Participants were 199 Roux-en-Y gastric bypass (RYGB) surgery patients. The International Physical Activity Questionnaire (IPAQ) was used to categorize participants into three groups according to their preoperative and /1-year postoperative PA level: (i) Inactive/Active (<200-min/week/≥200-min/week), (ii) Active/Active (≥200-min/week/greater ≥200-min/week) and (iii) Inactive/Inactive (<200-min/week/<200-min/week). The Medical Outcomes Study Short Form-36 (SF-36) was used to assess HRQoL. Analyses of covariance were conducted to examine the effects of PA group on weight and HRQoL changes. Inactive/Active participants, compared with Inactive/Inactive individuals, had greater reductions in weight (52.5 ± 15.4 vs. 46.4 ± 12.8 kg) and BMI (18.9 ± 4.6 vs. 16.9 ± …

Weight-Loss Maintenance In Successful Weight Losers: Surgical Vs. Non-Surgical Methods, D. S. Bond, Suzanne Phelan, T. M. Leahey, James O. Hill, Rena R. Wing

Kinesiology and Public Health

Objective: As large weight losses are rarely achieved through any method except bariatric surgery, there have been no studies comparing individuals who initially lost large amounts of weight through bariatric surgery or non-surgical means. The National Weight Control Registry (NWCR) provides a resource for making such unique comparisons. This study compared the amount of weight regain, behaviors and psychological characteristics in NWCR participants who were equally successful in losing and maintaining large amounts of weight through either bariatric surgery or non-surgical methods.
Design: Surgical participants (n=105) were matched with two non-surgical participants (n=210) on gender, entry weight, maximum weight loss …

Mechanisms Underlying The Association Between Breastfeeding And Obesity, Cynthia J. Bartok, Alison K. Ventura

Kinesiology and Public Health

Decades of epidemiological research have established that breastfeeding is associated with a modest reduction in risk of later overweight and obesity. However, no systematic effort has been made to delineate the mechanisms that may explain this association. This review summarizes evidence from a variety of disciplines to understand the potential mechanisms underlying this association. One possibility is that this association is spurious and that confounding factors fully or partially explain this association. Additionally, breastfeeding could confer protection by: encouraging the infant's emerging capabilities of self-regulation of intake; reducing problematic feeding behaviors on the part of caregivers that interfere with the …

Opportunities For The Primary Prevention Of Obesity During Infancy, Ian M. Paul, Cynthia J. Bartok, Danielle S. Downs, Cynthia A. Stifter, Alison K. Ventura, Leann L. Birch

Kinesiology and Public Health

Are chubby babies healthy babies? Whereas most seem well during infancy, evidence is increasing that heavier babies have a poorer long-term health trajectory than their trimmer counterparts. Data have emerged over the past 2 decades that early life growth patterns and behaviors play an important role in the etiology of obesity, yet there has been very little focus on the primary prevention of obesity during infancy by the medical, behavioral health, and public health communities. A recent report from the National Health and Nutrition Examination Survey (NHANES) highlighted the need for very early intervention when it revealed that between 2003 …

Maintaining Large Weight Losses: The Role Of Behavioral And Psychological Factors, Rena R. Wing, George Papandonatos, Joseph L. Fava, Amy A. Gorin, Suzanne Phelan, Jeanne Mccaffery, Deborah F. Tate

Kinesiology and Public Health

Few studies have examined predictors of weight regain after significant weight losses. This prospective study examined behavioral and psychological predictors of weight regain in 261 successful weight losers who completed an 18-month trial of weight regain prevention that compared a control condition with self-regulation interventions delivered face-to-face or via the Internet. Linear mixed effect models were used to examine behavioral and psychological predictors of weight regain, both as main effects and as interactions with treatment group. Decreases in physical activity were related to weight regain across all 3 groups, and increased frequency of self-weighing was equally protective in the 2 …

Patellofemoral Pain Syndrome (Pfps): A Systematic Review Of Anatomy And Potential Risk Factors, Gregory R. Waryasz, Ann Y. Mcdermott

Kinesiology and Public Health

Patellofemoral Pain Syndrome (PFPS), a common cause of anterior knee pain, is successfully treated in over 2/3 of patients through rehabilitation protocols designed to reduce pain and return function to the individual. Applying preventive medicine strategies, the majority of cases of PFPS may be avoided if a pre-diagnosis can be made by clinician or certified athletic trainer testing the current researched potential risk factors during a Preparticipation Screening Evaluation (PPSE). We provide a detailed and comprehensive review of the soft tissue, arterial system, and innervation to the patellofemoral joint in order to supply the clinician with the knowledge required to …

Holiday Weight Management By Successful Weight Losers And Normal Weight Individuals, Suzanne Phelan, Rena R. Wing, Hollie A. Raynor, Julia Dibello, Kim Nedeau, Wanfeng Peng

Kinesiology and Public Health

This study compared weight control strategies during the winter holidays among successful weight losers (SWL) in the National Weight Control Registry and normal weight individuals (NW) with no history of obesity. SWL (n = 178) had lost a mean of 34.9 kg and had kept =13.6 kg off for a mean of 5.9 years. NW (n = 101) had a body mass index of 18.5-24.9 kg/m². More SWL than NW reported plans to be extremely strict in maintaining their usual dietary routine (27.3% vs. 0%) and exercise routine (59.1% vs. 14.3%) over the holidays. Main effects for group indicated that …

Does Parenting Affect Children's Eating And Weight Status?, Alison K. Ventura, Leann L. Birch

Kinesiology and Public Health

Background: Worldwide, the prevalence of obesity among children has increased dramatically. Although the etiology of childhood obesity is multifactorial, to date, most preventive interventions have focused on school-aged children in school settings and have met with limited success. In this review, we focus on another set of influences that impact the development of children's eating and weight status: parenting and feeding styles and practices. Our review has two aims: (1) to assess the extent to which current evidence supports the hypothesis that parenting, via its effects on children's eating, is causally implicated in childhood obesity; and (2) to identify a …

Effects Of Short-Term Exercise And Energy Surplus On Hormones Related To Regulation Of Energy Balance, Todd A. Hagobian, Carrie G. Sharoff, Barry Braun

Kinesiology and Public Health

Energy surplus raises circulating concentrations of leptin and insulin while lowering plasma ghrelin. Exercise has the opposite effects. The purpose of this study was to determine whether exercise counters the hormonal effects of energy surplus independent of changes in energy balance. To do that, we assessed plasma concentrations of leptin, insulin, and ghrelin at baseline, after overfeeding, and after overfeeding plus exercise. Baseline (B) leptin and insulin concentrations and ghrelin area under the curve were measured during an oral glucose challenge in 9 healthy, active subjects (6 male, 3 female) after 2 days in energy balance without exercise. Measurements were …

Impact Of Metformin On Peak Aerobic Capacity, Barry Braun, Pamela Eze, Brooke R. Stephens, Todd A. Hagobian, Carrie G. Sharoff, Stuart R. Chipkin, Benjamin Goldstein

Kinesiology and Public Health

Individually, exercise and the drug metformin have been shown to prevent or delay type 2 diabetes. Metformin mildly inhibits complex I of the electron transport system and may impact aerobic capacity in people exercising while taking metformin. The purpose of the study was to evaluate the effects of metformin on maximal aerobic capacity in healthy individuals without mitochondrial dysfunction. Seventeen healthy, normal-weight men (n=11) and women (n=6) participated in a double-blind, placebo-controlled, cross-over design. Peak aerobic capacity was measured twice using a continuous, incrementally graded protocol; once after 7-9 d of metformin (final dose=2000 mg/d) and once with placebo, with …

Mediterranean Diet And Breast Density In The Minnesota Breast Cancer Family Study, Marilyn Tseng, Thomas A. Sellers, Robert A. Vierkant, Lawrence H. Kushi, Celine M. Vachon

Kinesiology and Public Health

Mediterranean populations’ lower breast cancer incidence has been attributed to a traditional Mediterranean diet, but few studies have quantified Mediterranean dietary pattern intake in relation to breast cancer. We examined the association of a Mediterranean diet scale (MDS) with mammographic breast density as a surrogate marker for breast cancer risk. Participants completed a dietary questionnaire and provided screening mammograms for breast density assessment using a computer-assisted method. Among 1,286 women, MDS was not clearly associated with percent density in multivariate linear regression analyses. Because of previous work suggesting dietary effects limited to smokers, we conducted stratified analyses and found MDS …

Dietary Patterns And Breast Density In The Minnesota Breast Cancer Family Study, Marilyn Tseng, Robert A. Vierkant, Lawrence H. Kushi, Thomas A. Sellers, Celine M. Vachon

Kinesiology and Public Health

Objective Whether dietary patterns, rather than single foods or nutrients, are associated with breast density is not known. We investigated this in the Minnesota Breast Cancer Family Study. Methods Participants completed a 153-item food frequency questionnaire and provided screening mammograms for breast density assessment using a computer-assisted method. We used multivariate linear regression to quantify dietary pattern–breast density associations. Results Among 3,147 women with dietary information, three dietary patterns emerged from principal components analysis: a fruit–vegetable–cereal pattern, a salad–sauce–pasta/ grain pattern, and a meat–starch pattern. Among 1,286 women with breast density estimates, the fruit–vegetable–cereal and salad–sauce–pasta/grain patterns were inversely associated …

Food Frequency Questionnaires And Overnight Urines Are Valid Indicators Of Daidzein And Genistein Intake In U.S. Women Relative To Multiple 24-H Urine Samples, Marilyn Tseng, Temitope Olufade, Mindy S. Kurzer, Kristiina Wahala, Carolyn Y. Fang, Yvonne T. Van Der Schouw, Mary B. Daly

Kinesiology and Public Health

Data regarding convenient, valid methods for measuring U.S. isoflavone intake are limited. We evaluated a soy food questionnaire (SFQ), the Willett food frequency questionnaire (FFQ), and overnight urine samples relative to excretion in 24-h urine samples. We also described intake among women in a high-risk program for breast or ovarian cancer. Between April 2002 and June 2003, 451 women aged 30 to 50 yr with a family history of breast or ovarian cancer completed the SFQ and FFQ. Of them, 27 provided four 24-h and overnight urine specimens. In these women, 24-h sample measures were correlated with SFQ estimates of …

Metabolic Syndrome And Health-Related Quality Of Life In Obese Individuals Seeking Weight Reduction, Adam Gilden Tsai, Thomas A. Wadden, David B. Sarwer, Robert I. Berkowitz, Leslie G. Womble, Louise A. Hesson, Suzanne Phelan, Rebecca Rothman

Kinesiology and Public Health

Background: No previous research has examined the association between metabolic syndrome (MetSyn) and health-related quality of life (HRQoL) using standard criteria for defining MetSyn. We hypothesized that MetSyn would be associated with lower HRQoL on measures of physical and mental health.
Methods and Procedures: Participants were 361 individuals in two randomized weight loss trials. MetSyn was defined by the National Cholesterol Education Panel criteria. The Medical Outcomes Study, Short Form-36 (SF-36) was used to assess HRQoL. Differences in HRQoL and in clinical and psychosocial characteristics were compared among participants with and without MetSyn. Multiple regression was used to determine predictors …

Kinesiology and Public Health

Objective: The National Weight Control Registry (NWCR) was established in 1993 to examine the characteristics of those who are successful at weight loss: individuals maintaining a 13.6-kg weight loss for >1 year. The size of the registry has increased substantially since the early descriptions of this group a decade ago. The purpose of this study was to describe in detail the weekly physical activity habits of NWCR members, to examine the relationship between amount of activity and demographic characteristics, and to determine if changes in activity parameters have occurred over time.
Methods and Procedures: Participants were 887 men and 2,796 …

Consistent Self-Monitoring Of Weight: A Key Component Of Successful Weight Loss Maintenance, Meghan L. Butryn, Suzanne Phelan, James O. Hill, Rena R. Wing

Kinesiology and Public Health

Objective: The objectives were to investigate the characteristics associated with frequent self-weighing and the relationship between self-weighing and weight loss maintenance.
Research Methods and Procedures: Participants (n = 3003) were members of the National Weight Control Registry (NWCR) who had lost ≥30 lbs, kept it off for ≥1 year, and had been administered the self-weighing frequency assessment used for this study at baseline (i.e., entry to the NWCR). Of these, 82% also completed the one-year follow-up assessment.
Results: At baseline, 36.2% of participants reported weighing themselves at least once per day, and more frequent weighing was associated with lower BMI …

Why Do High School Seniors Drink? Implications For A Targeted Approach To Intervention, Donna L. Coffman, Megan E. Patrick, Lori Ann Palen, Brittany L. Rhoades, Alison K. Ventura

Kinesiology and Public Health

The transition from high school to college provides a potentially critical window to intervene and reduce risky behavior among adolescents. Understanding the motivations (e.g., social, coping, enhancement) behind high school seniors’ alcohol use could provide one important avenue to reducing risky drinking behaviors. In the present study, latent class analysis was used to examine the relationship between different patterns of drinking motivations and behaviors in a sample of 12th graders (N = 1,877) from the 2004 Monitoring the Future survey. Unlike previous variable-centered analyses, this person-centered approach identifies types of motivations that cluster together within individuals and relates membership …

Empirical Evaluation Of Physical Activity Recommendations For Weight Control In Women, Suzanne Phelan, Marta Roberts, Wei Lang, Rena R. Wing

Kinesiology and Public Health

Purpose:Recent recommendations advise 30-60 min of physical activity per day to prevent weight gain and 60-90 min to prevent weight regain. No studies have used objective measures of physical activity to verify these public health recommendations. The purpose of this study was to use objective measures to quantify the amount and intensity of physical activity in a weight-loss-maintainer group and an always-normal-weight group, and, thus, empirically evaluate the recommendations for prevention of weight gain versus regain.

Methods: The weight-loss-maintainer group (N= 135) lost ≥ 30.6 kg, maintained ≥ 10% weight loss for 14.2 yr, and had a BMI of …

Internal Disinhibition Predicts Weight Regain Following Weight Loss And Weight Loss Maintenance, Heather M. Niemeier, Suzanne Phelan, Joseph L. Fava, Rena R. Wing

Kinesiology and Public Health

Objective: The disinhibition scale of the Eating Inventory predicts weight loss outcome; however, it may include multiple factors. The purpose of this study was to examine the factor structure of the disinhibition scale and determine how its factors independently relate to long-term weight loss outcomes.
Research Methods and Procedures: Exploratory factor analysis of the disinhibition scale was conducted on 286 participants in a behavioral weight loss trial (TRIM), and confirmatory factor analysis was conducted on 3345 members of the National Weight Control Registry (NWCR), a registry of successful weight loss maintainers. Multivariate regressions were used to examine the relationships between …

Dietary Patterns And Breast Cancer Risk In The Shanghai Breast Cancer Study, Xiaohui Cui, Qi Dai, Marilyn Tseng, Xiao-Ou Shu, Yu-Tang Gao, Wei Zheng

Kinesiology and Public Health

The association of breast cancer with dietary patterns such as a western diet has not been studied in Asian women. We examined this among Shanghai Breast Cancer Study participants. Cases were of ages 25 to 64 years, diagnosed 08/1996-03/ 1998, and identified through a rapid case ascertainment system supplemented by the Shanghai Cancer Registry. Controls, selected from the general population of urban Shanghai, were frequency matched to cases by 5-year age group. Participants provided information on diet, lifestyle, and reproductive factors. In principal component analysis among 1,556 controls, two patterns emerged. a ‘‘vegetable-soy’’ pattern (tofu, cauliflower, beans, bean sprouts, green …

Dietary Intake And Breast Density In High-Risk Women: A Cross-Sectional Study, Marilyn Tseng, Celia Byrne, Kathryn A. Evers, Mary B. Daly

Kinesiology and Public Health

Background Women with a family history of breast cancer may be at higher risk for breast cancer, but few previous studies evaluating diet and breast cancer have focused on such women. The objective of the present study was to determine whether diet, a modifiable risk factor, is related to breast density among women at high genetic risk for breast cancer. Methods Women with at least one first-degree or second-degree relative with breast cancer or ovarian cancer participating in the Fox Chase Cancer Center Family Risk Assessment Program completed health history and food frequency questionnaires and received standard screening mammograms. Cranial–caudal …

Girls’ Dairy Intake, Energy Intake, And Weight Status, Laura M. Fiorito, Alison K. Ventura, Diane C. Mitchell, Helen Smiciklas-Wright, Leann L. Birch

Kinesiology and Public Health

We explored the relationships among girls’ weight status, dairy servings, and total energy intake. The hypothesis that consuming dairy could reduce risk for overweight was evaluated by comparing energy intake and weight status of girls who met or consumed less than the recommended three servings of dairy per day. Participants included 172 11-year-old non-Hispanic white girls, assessed cross-sectionally. Intakes of dairy, calcium, and energy were measured using three 24-hour recalls. Body mass index and body fat measures from dual-energy x-ray absorptiometry were obtained. Because preliminary analyses suggested systematic underreporting of energy intake, the relationships among dairy servings and measures of …
