Adolescent Lifestyle Factors And Adult Breast Density In U.S. Chinese Immigrant Women, Marilyn Tseng, Temitope O. Olufade, Kathryn A. Evers, Celia Byrne

Kinesiology

We examined recalled measures of adolescent diet, physical activity, and body size in relation to adult breast density in 201 U.S. Chinese immigrant women recruited in January 2002 to May 2003 from Philadelphia region screening programs. Mammographic images were classified into 1 of 4 categories ranging from “entirely fatty” to “extremely dense.” Questionnaires assessed diet and physical activity between ages 12–17, relative weight and height at age 10, and weight at age 18. To estimate odds ratios (ORs), we conducted logistic regression analyses using proportional odds models for polychotomous outcomes. Higher adult breast density was significantly associated with ...


Adiposity, Adult Weight Gain And Mammographic Breast Density In Us Chinese Women, Marilyn Tseng, Celia Byrne Jan 2011

Adiposity, Adult Weight Gain And Mammographic Breast Density In Us Chinese Women, Marilyn Tseng, Celia Byrne

Kinesiology

The association of adiposity with dense tissue area in the breast is unclear, but suggests a mechanism by which adiposity might increase breast cancer risk. We examined associations of body mass index (BMI), usual BMI from age 20 to 29, waist circumference and adult weight gain with breast density in a sample of premenopausal United States Chinese immigrant women. Analyses included 415 participants in a longitudinal breast density study in Philadelphia. In addition to detailed questionnaire information, data collection included measures of anthropometry, and assessment of mammographic breast density using a computer-assisted method. We used multivariate linear regression to quantify ...

Improved Dietary Variety And Adequacy But Lower Dietary Moderation With Acculturation In Chinese Women In The United States, Amy Liu, Zekarias Berhane, Marilyn Tseng

Kinesiology

Acculturation is associated with increased chronic disease risk among Asian Americans, but its association with different aspects of diet quality remains unclear. Associations of acculturation with diet quality were examined in a convenience sample of 243 Chinese participants in a study of diet and mammographic density in the Philadelphia region between January 2002 to May 2003. An acculturation index was created based on self-reported English proficiency and within-and cross-ethnicity social interactions. Diet Quality Index-International (DQI-I) scores were based on responses to an 88-item food frequency questionnaire. Odds ratios (ORs) for falling into a higher vs lower quartile for DQI-I and ...


Pregnancy: A "Teachable Moment" For Weight Control And Obesity Prevention, Suzanne Phelan Feb 2010

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

Kinesiology

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 ...

Preventing Childhood Obesity: What Works?, Ll Birch, A K. Ventura Apr 2009

Preventing Childhood Obesity: What Works?, Ll Birch, A K. Ventura

Kinesiology

Rates of overweight in North American children and adolescents have increased dramatically since the 1970s. Childhood obesity has reached epidemic proportions and calls for prevention and treatment programs to reverse this trend have been made. However, the evidence base needed for effective action is still incomplete, especially for childhood obesity prevention programs. This paper focuses on primary prevention of childhood obesity and has three aims: (1) to briefly describe current primary prevention approaches for childhood obesity and the evidence for their impact; (2) to elucidate promising, but untested intervention strategies using an ecological framework and evidence from experimental and epidemiological ...

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

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 ...


Mechanisms Underlying The Association Between Breastfeeding And Obesity, Cynthia J. Bartok, Alison K. Ventura Jan 2009

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

Kinesiology

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 ...

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

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 ...

Kinesiology

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 ...

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

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 ...
