Faculty Publications

The purpose of this study was to identify racial differences in physical activity (PA), fitness, and BMI in female 8th-grade sports participants and nonparticipants. Girls from 31 South Carolina middle schools (N=1,903, 48% White; mean age=13.6 ± 0.63) reported PA and previous year sports-team participation, completed a submaximal fitness test, and had height and weight measured. Sports team participation was positively associated with PA and negatively associated with television viewing and BMI, in a dose-response manner. Compared with Whites, African-Americans reported less PA and more television viewing, and had greater BMI scores. Whereas PA intervention programs that incorporate …

Paripartum Cardiomyopathy: Implications For Nps, Jeffrey A. Goss, A. Elaine Bond, Renea L. Beckstrand, Lynn C. Callister

Faculty Publications

Peripartum cardiomyopathy (PPCM), the fifth leading cause of death in pregnancy, is often overlooked or misdiagnosed because of vague symptoms and a lack of specific criteria for diagnosis. The authors performed a literature review of articles published between January 2000 and November 2007, and found that early diagnosis via echocardiography and interventions with specific treatment modalities can reduce mortality. Dobutamine stress testing may be prognostic for left ventricular (LV) dysfunction. Standard heart failure (HF) drug regimens, heart transplantation, and mechanical assist devices are viable treatment modalities, depending on individual needs. Subsequent pregnancies must be followed closely. The authors recommend that …

Faculty Publications

Clinical nursing instructors are continually telling their students that they just need more confidence. But how do students find this needed confidence and how can nursing instructors help them? The author discusses sources and principles of confidence in relationship to teaching behaviors and strategies for increasing self-confidence, such as simulations, peer modeling, story telling, skill review sessions, and journaling.

Accumulating Disadvantage Over The Life Course: Evidence From A Longitudinal Study Investigating The Relationship Between Educational Advantage In Youth And Health In Middle Age, Katrina M. Walsemann, Arline T. Geronimus, Gilbert C. Gee

Faculty Publications

Recent studies suggest the importance of examining cumulative risk or advantage as potential predictors of health over the life course. Researchers investigating the cumulative health effects of education, however, have mainly conceptualized education in years or degrees, often disregarding educational quality and access to educational opportunities that may place individuals on divergent academic trajectories. We investigate whether educational advantages in youth are associated with an individual's health trajectory. We develop a novel index of educational advantage and employ random-intercept modeling using data from the National Longitudinal Survey of Youth. We find a widening health disparity in adulthood between respondents with …

Novel Role Of Antioxidant-1 (Atox1) As A Copper-Dependent Transcription Factor Involved In Cell Proliferation, S. Itoh, H. W. Kim, O. Nakagawa, K. Ozumi, Susan M. Lessner, H. Aoki, K. Akram, R. D. Mckinney, M. Ushio-Fukai, T. Fukai

Faculty Publications

Copper plays a fundamental role in regulating cell growth. Many types of human cancer tissues have higher copper levels than normal tissues. Copper can also induce gene expression. However, transcription factors that mediate copper-induced cell proliferation have not been identified in mammals. Here we show that antioxidant-1 (Atox1), previously appreciated as a copper chaperone, represents a novel copper-dependent transcription factor that mediates copper-induced cell proliferation. Stimulation of mouse embryonic fibroblasts (MEFs) with copper markedly increased cell proliferation, cyclin D1 expression, and entry into S phase, which were completely abolished in Atox1^-/- MEFs. Promoter analysis and EMSA revealed that copper …

Articulatory Changes Following Treatment Of Muscle Tension Dysphonia: Preliminary Acoustic Evidence, Christopher Dromey, Shawn L. Nissen, Ray M. Merrill, Nelson Roy

Faculty Publications

Purpose: Primary muscle tension dysphonia (MTD), a voice disturbance that occurs in the absence of structural or neurological pathology, may respond to manual circumlaryngeal techniques, which ostensibly alter the posture of the larynx and/or the configuration of the vocal folds without directly targeting supralaryngeal articulatory structures. Although the phonatory benefits of these techniques have been documented previously, this investigation examined whether acoustic evidence exists for articulatory changes accompanying successful management. Method: In this retrospective study of a clinical database, pre- and post-treatment speech samples from 111 women with MTD were analyzed for acoustic evidence of supraglottal vocal tract changes associated …

Child Psychosocial Adjustment And Parenting In Families Affected By Maternal Hiv/Aids, Tanya L. Tompkins, Gail E. Wyatt

Faculty Publications

Child adjustment and parenting were examined in 23 9-through 16-year-old youth from families affected by maternal HIV infection and 20 same-age peers whose mothers were not infected. Children whose mothers were seropositive reported significantly more externalizing problems. Infected mothers reported less age-appropriate supervision/monitoring relative to non-infected mothers. Better mother-child relationship quality and less impairment in parental supervision/monitoring of age-appropriate youth behaviors were associated with fewer externalizing difficulties among the HIV-positive group only. Similarly, only among HIV-infected mothers was refraining from engaging in inconsistent disciplinary tactics associated with lower reports of internalizing and externalizing problems. These data highlight the promise of …

Disparities In Use Of Mental Health And Substance Abuse Services By Asian And Native Hawaiian/Other Pacific Islander Women, Van M. Ta Park, H. S. Juon, A. C. Gielen, D. Steinwachs, A. Duggan

Substance Use And Social Identity In The Lesbian Community_Jls.Pdf, Molly Kerby

Faculty Publications

Although the study results report discrepancies in the rates of substance abuse in the lesbian community, the general consensus in the field of gay and lesbian studies is that these individuals, as a whole, have a higher rate of substance use. For this study, data were collected via the Internet on the use of drugs and alcohol, level of self-esteem, and degree of social identity in the lesbian community. A correlation analysis was used to determine if negative social identity within the lesbian community leads to low self-esteem that is reflected in higher rates of substance abuse. Though a positive …

An Uncertain Privilege: Implied Waiver And The Eviseration Of The Psychotherapist Patient Privilege In The Feral Courts, Deirdre M. Smith

Faculty Publications

Twelve years ago in Jaffee v. Redmond, 518 U.S. 1 (1996), the United States Supreme Court first recognized a federal common law psychotherapist-patient privilege and held that federal courts must protect confidential communications arising in psychotherapy despite the "likely evidentiary benefit" of such communications. This article examines the sharply conflicting authority in the federal courts that has developed since that landmark decision on the question of whether a plaintiff to a civil lawsuit waives the psychotherapist-patient privilege merely by seeking emotional distress damages. The federal courts' inconsistent and unprincipled approaches to this question renders the privilege itself nearly illusory and …

Where's The Kale? Environmental Availability Of Fruits And Vegetables In Two Racially Dissimilar Communities, Edith M. Williams, Bamidele O. Tayo, Beverly Mclean, Ellen Smit, Christopher T. Sempos, Carlos J. Crespo

Faculty Publications

Minority communities across the United States have limited numbers of stores that offer a variety of fruits and vegetables, creating major barriers to good eating habits and nutritional practices among minority groups such as African Americans. Factors like environmental availability of healthy food options have not been fully investigated as possible sources of current cross-population differences in disease. The present study examined whether a predominantly African American neighborhood had disproportionately less availability of fruits and vegetables than a predominantly non-Hispanic White neighborhood. Availability was judged on the bases of the types of stores available in each community and the specific …

Physical Activity And Blood Pressure In Childhood: Findings From A Population-Based Study, Sam D. Leary, Andy R. Ness, George Davey Smith, Calum Mattocks, Kevin Deere, Steven N. Blair, Chris J. Riddoch

Faculty Publications

The pathological processes associated with development of cardiovascular disease begin early in life. For example, elevated blood pressure (BP) can be seen in childhood and tracks into adulthood. The relationship between physical activity (PA) and BP in adults is well-established, but findings in children have been inconsistent, with few studies measuring PA mechanically. Children aged 11 to 12 years were recruited from the Avon Longitudinal Study of Parents and Children. 5505 had systolic and diastolic BP measurements, plus valid (at least 10 hours for at least 3 days) accelerometer measures of PA; total PA recorded as average counts per minute …

Blair, Julian Shield, Kevin Deere, Joanne Saunders, Joanne Krikby, George Davey Smith, Jonathan Wells, Nicholas Wareham, John J. Reilly, Chris J. Riddoch

Faculty Publications

Background: Objective methods can improve accuracy of physical activity measurement in field studies but uncertainties remain about their use.

Methods: Children age 11 years from the Avon Longitudinal Study of Parents and Children (ALSPAC), were asked to wear a uni-axial accelerometer (MTI Actigraph) for 7 days.

Results: Of 7159 children who attended for assessment, 5595 (78%) provided valid measures. The reliability coefficient for 3 days of recording was .7 and the power to detect a difference of 0.07 SDs (P ≤ .05) was > 90%. Measures tended to be higher on the first day of recording (17 counts/min; 95% CI, …

Individual Differences In The Conceptualization Of Food Across Eating Contexts, Christine E. Blake

Faculty Publications

Individual differences in food-related knowledge structures were explored by applying schema theory to examine the categories 42 adults used to classify foods across four eating contexts. Food card-sort labels were organized in 12 categories, category salience for each person was evaluated, and cluster analysis was used to identify clusters of participants according to the salience of their categories. Clusters were further evaluated for complexity and consistency of category use across contexts. Seven food schema clusters were identified. Meal/time and Routine categories were the most salient overall and were used by most clusters. Well-being, Person, Source, Convenience, Meal component, and Food …

The Effect Of Question Order On Reporting Physical Activity And Walking Behavior, Brent E. Hutto, Patricia A. Sharpe, Michelle L. Granner, Cheryl L. Addy, Steven P. Hooker

Faculty Publications

Background: Question order might affect self-reported regular physical activity (PA) measured with items from the Behavioral Risk Factor Surveillance System (BRFSS) PA module. Methods: A telephone survey was conducted using 2 forms (N = 1004, N = 212) with varying PA question order. The standard form presented moderate-PA, vigorous-PA, and walking questions, in that order, whereas the alternate form presented walking questions, followed by moderate-PA, and then vigorous-PA questions. Weighted, adjusted rates of vigorous PA, walking, meeting the Centers for Disease Control and Prevention (CDC) recommendation for moderate or vigorous PA, and moderate PA from each form were compared. Results: …

The Effects Of Divided Attention On Speech Motor, Verbal Fluency, And Manual Task Performance, Christopher Dromey, Erin Shim

Faculty Publications

Purpose: The goal of this study was to evaluate aspects of the functional distance hypothesis, which predicts that tasks regulated by brain networks in closer anatomic proximity will interfere more with each other than tasks controlled by spatially distant regions. Speech, verbal fluency, and manual motor tasks were examined to ascertain whether right-handed activity would interfere more with speech and language performance, because of the presumed greater demands on the left hemisphere.

Method: Twenty young adults completed a speech task (repeating a sentence), a verbal fluency task (listing words beginning with the same letter), and right- and left-handed motor tasks …

The project purpose was too determine whether measures of critical thinking show differences between three groups (simulator, non-simulator, control) of baccalaureate nursing students. The second purpose was to determine the moderating effect of students' preferred learning style. All groups experienced a moderate to large effect size in critical thinking scores. The corrected model for the total scale gain score was statistically significant but not significant for learning style or group.

Towards An Understanding Of Salient Neighborhood Boundaries: Adolescent Reports Of An Easy Walking Distance And Convenient Driving Distance, Natalie Colabianchi, Marsha Dowda, Karin A. Pfeiffer, Dwayne E. Porter, Maria João C. A. Almeida, Russell R. Pate

Faculty Publications

Numerous studies have examined the association between the surrounding neighborhood environment and physical activity levels in adolescents. Many of these studies use a road network buffer of Euclidean distance buffer around an adolescent's home to represent the appropriate geographic area for study (i.e., neighborhood). However, little empirical research has examined the appropriate buffer size to use when defining this area and there is little consistency across published research as to the buffer size used. In this study, 909 12^th grade adolescent girls of diverse racial and geographic backgrounds were asked to report their perceptions of an easy walking distance …

Objectively Assessed Associations Between Physical Activity And Body Composition In Middle-School Girls: The Trial Of Activity For Adolescent Girls, June Stevens, David M. Murray, Chris C. Baggett, John P. Elder, Timothy G. Lohman, Leslie A. Lytle, Russell R. Pate, Charlotte A. Pratt, Margarita S. Treuth, Larry S. Webber, Deborah Rohm Young

Faculty Publications

Declining levels of physical activity probably contribute to the increasing prevalence of overweight in US youth. In this study, the authors examined cross-sectional and longitudinal associations between physical activity and body composition in sixth- and eighth-grade girls. In 2003, girls were recruited from six US states as part of the Trial of Activity for Adolescent Girls. Physical activity was measured using 6 days of accelerometry, and percentage of body fat was calculated using an age- and ethnicity-specific prediction equation. Sixth-grade girls with an average of 12.8 minutes of moderate-to-vigorous physical activity (MVPA) per day (15th percentile) were 2.3 times (95% …
