Item Cardiorespiratory Fitness, Body Mass Index and All-Cause Mortality in Women, ACLS 1970-1994(1999-12-01) Braun, LeeAnn; Blakley, Sally; Rene, Antonio A.Braun, LeeAnn, Cardiorespiratory Fitness, Body Mass Index and All-Cause Mortality in Women, Aerobics Center Longitudinal Study, 1970-1994. Master of Public Health (Epidemiology), December, 1999, 44 p.p., 9 tables, references, 24 titles. Cardiorespiratory fitness and body mass index are related to morbidity and mortality (Manson, 1996). There is a preponderance of evidence supporting this relation in men (Gibbons, 1983; Blair, 1989, 1995, 1996; Lee, I, 1993; Barlow, 1995; Kampert, 1996; Dorn, 1997; Lee, C, 1999). The evaluation of the stated risk factors have been virtually unexplored in a cohort of women. The aim of this study is to evaluate whether higher levels of cardiorespiratory fitness attenuate the risk of all-cause mortality in overweight and obese women. In this prospective study, the study population consisted of 7572 women ages 20-89 years, who had a medical examination and achieved at least 85% of their age-adjusted maximal heart rate during a maximal treadmill test were followed for 69,979 woman-years. After adjustment for age, exam year, health status and smoking status, unfit women had a higher risk for all-cause mortality across BMI categories [RR 1.70 95% CI (1.18, 2.43)]. The benefits of cardiorespiratory fitness significantly decrease the risk of all-cause mortality in women as the concurrent consideration of cardiorespiratory fitness.Item Pilot Project Evaluation: Keep It Healthy - An Obesity-Prevention and Lifestyle-Modification Non-Profit Organization(2007-05-01) Bhatia, Shimona R.; Coggin, Claudia; Urrutia-Rojas, Ximena; Bae, SejongBhatia, Shimona R., Pilot Project Evaluation: Keep It Healthy- An Obesity Prevention and Lifestyle-Modification Non-Profit Organization. Master of Public Health (Community Health), May 2007, 120 pp., 3 tables, 5 illustrations, references, 66 titles. This study was a secondary data set analysis and pilot-project evaluation of the Keep It Healthy non-profit organization. The eighteen-week program, which twenty-one qualifying participants completed, included dietary counseling, physical activity groups and classes as well as nutritional education. Overall, there was a significant (p-value [less than] 0.05) increase in fruit and vegetable consumption per day. There was also an increase in the days per week and minutes per day spent engaging in various levels of physical activity. There was also a significant decrease of average weight (164.10 to 169.49 pounds) and average body mass index (BMI) (30.04 to 29.14) of the group over the eighteen-week program.Item The Effects of Cardiorespiratory Fitness and Body Mass Index on the Development of Osteoarthritis in Women(2001-05-01) Hathwar, Supriya; Blakley, Sally; Blair, Steven; Rene, AntonioHathwar, Supriya, The Effect of Cardiorespiratory Fitness and Body Mass Index on the Development of Osteoarthritis in Women, (ACLS 1970-1999). Master of Public Health (Epidemiology), May, 35 pp., 6 tables, references, 48 titles. Osteoarthritis (OA) of the hip and knee is one of the most important causes of pain and disability affecting nearly 21 million people in the United States. Obesity is one of the primary causes of secondary osteoarthritis especially of the hip and knee. (Felson, 1992). The aim of this prospective cohort study is to determine whether higher levels of CRF reduce the risk of development of OA in women across different body mass index (BMI) levels. The study population consisted of 3847 women, ages 20-87, examined at the Cooper Clinic, Dallas, Texas between 1970 and 1999. There were 379 cases of physician-diagnosed OA during 31,657 woman-years of follow-up. After adjustment for age, exam year and health status, obesity and overweight were found to be significant predictors of OA in women. At all levels of CRF, the odds of developing OA increase as weight increases. In the overweight category, the odds of developing OA are 80% higher among the low-fit women [OR=1.8,95% CI (1.1-3.1)], and 60% higher among the moderately fit women [OR=1.6,95%CI (1.0-2.3)] compared to high fit, normal weight women. In the obese category, the low-fit and the high fit women had the same odds of developing OA (OR=2.6), while moderately fit women had lower odds of developing OA (OR=1.7). These data suggest that CRF is not a consistent predictor for development of OA in women.
