Association Of Physical Activity With Hormone Receptor Status: The Shanghai Breast Cancer Study, Swann Arp Adams, Charles E. Matthews, James R. Hébert, Charity G. Moore, Joan E. Cunningham, Xiou-Oi Shu, Jeanette Fulton, Yutang Gao, Wei Zheng

Faculty Publications

Evidence exists that breast tumors differing by estrogen receptor (ER) and progesterone receptor (PR) status may be phenotypically distinct diseases resulting from dissimilar etiologic processes. Few studies have attempted to examine the association of physical activity with breast cancer subtype. Such research may prove instructive into the biological mechanisms of activity. Consequently, this investigation was designed to assess the relationship between physical activity and hormone receptor-defined breast cancers in a population of Asian women in which the distribution of receptor types differed from traditional Western populations. Participants, ages 25 to 64 years, were recruited into this population-based, case-control study of …

Criterion Validity Of The Pittsburgh Sleep Quality Index: Investigation In A Non-Clinical Sample, Michael A. Grandner, Daniel F. Kripke, In-Young Yoon, Shawn D. Youngstedt

Faculty Publications

The objective of this study was to investigate the reliability and validity of the Pittsburgh Sleep Quality Index (PSQI) in a non-clinical sample consisting of younger and older adults. There has been little research validating the PSQI with respect to multinight recording as with actigraphy, and more validation is needed in samples not specifically selected for clinical disturbance. Also, the degree to which the PSQI scores may reflect depressive symptoms versus actual sleep disturbance remains unclear. One-hundred and twelve volunteers (53 younger and 59 older) were screened for their ability to perform treadmill exercises; inclusion was not based on sleep …

Association Between Tobacco Use And Body Mass Index In Urban Indian Population: Implications For Public Health In India, Mangesh S. Pednekar, Prakash C. Gupta, Heema C. Shukla, James R. Hébert

Faculty Publications

Background: Body mass index [BMI, weight (kg)/height (m2)], a measure of relative weight, is a good overall indicator of nutritional status and predictor of overall health. As in many developing countries, the high prevalence of very low BMIs in India represents an important public health risk. Tobacco, smoked in the form of cigarettes or bidis (handmade by rolling a dried rectangular piece of temburni leaf with 0.15–0.25 g of tobacco) or chewed, is another important determinant of health. Tobacco use also may exert a strong influence on BMI.

Methods: The relationship between very low BMI (< 18.5 kg/m2) and tobacco use was examined using data from a representative cross-sectional survey of 99,598 adults (40,071 men and 59,527 women) carried out in the city of Mumbai (formerly known as Bombay) in western India. Participants were men and women aged ≥ 35 years who were residents of the main city of Mumbai.

Using Focus Groups In The Consumer Research Phase Of A Social Marketing Program To Promote Moderate-Intensity Physical Activity And Walking Trail Use In Sumter County, South Carolina, Ericka L. Burroughs, Lara E. Peck, Patricia A. Sharpe, Michelle L. Granner, Carol A. Bryant, Regina Fields

Faculty Publications

Introduction: The use of social marketing approaches in public health practice is increasing. Using marketing concepts such as the "four Ps" (product, price, place, and promotion), social marketing borrows from the principles of commercial marketing but promotes beneficial health behaviors. Consumer research is used to segment the population and develop a strategy based on those marketing concepts. In a community-based participatory research study, 17 focus groups were used in consumer research to develop a social marketing program to promote walking and other moderate-intensity physical activities.

Methods: Two phases of focus groups were conducted. Phase 1 groups, which included …
