Physical Activity and Cardiovascular Risk in Black Girls Clinical Trials Information presented on Clinical Trials Search isn't designed to be a substitute for certified healthcare advice, travels to or professional assistance using a genuine medical doctor. We are not physicians. Always confer with your dr. about Physical Activity and Cardiovascular Risk in Black Girls conditions. Clinical Trials Search.org is a site devoted to listing clinical research studies in human subjects. Physical Activity and Cardiovascular Risk in Black Girls Clinical research trials and Physical Activity and Cardiovascular Risk in Black Girls medical trials happen in hundreds of places across the United States. A clinical trial or clinical study is a research project with human volunteer subjects. Clinical drug trials and pharmaceutical clinical trials usually measure the effectualness of new drugs. The intention of the studies / undertakings is to solve certain human healthcare questions. Clinical trials are a popular manner for mDs, government agencies, and private sector companies to locate treatments for all forms of circumstances, such as Physical Activity and Cardiovascular Risk in Black Girls. Physical Activity and Cardiovascular Risk in Black Girls Clinical Trials and other clinical trials allow for volunteers to undergo medical treatment choices before they are available to the general public. Some times the human subjects get treatment for free of charge, and sometimes they are paid for their time. Occasionally there is a cost for a Physical Activity and Cardiovascular Risk in Black Girls clinical trial. Participants frequently get the best healthcare available for their Physical Activity and Cardiovascular Risk in Black Girls condition. Risks are a reality, nonetheless, and can include extra or frequent physician trips, medical risks (possibly life-jeopardising), and/or the treatment being ineffective. Trials are federally governed with exacting guidelines to protect clinical trials subjects.

Physical Activity and Cardiovascular Risk in Black Girls
For Condition: Cardiovascular Diseases,Hypertension,Heart Diseases,Obesity
Status: Completed
Sponsor(s): National Heart, Lung, and Blood Institute (NHLBI) ,
Synopsis: To conduct a longitudinal study investigating the physical activity patterns, the psychosocial predictors of physical activity, and the effects of physical activity changes on blood pressure and body fatness in a cohort of African-American girls, ages 11-17.
Details: BACKGROUND: The study contributed to an underdeveloped area of research. Physical activity is recommended as a nonpharmacological means to modify hypertension and obesity, two cardiovascular risk factors. African-American women have low levels of physical activity and high rates of obesity, hypertension, and mortality from coronary heart disease, diabetes, and hypertensive diseases. In 1992, there was an absence of longitudinal data about the physical activity habits of African-American girls even though a decline in physical activity during adolescence had been reported in other subpopulations. DESIGN NARRATIVE: Within the framework of puberty and maturation, the study: 1) described longitudinal patterns of physical activity; 2) assessed longitudinal changes in physical activity and concomitant changes in blood pressure and body fatness; and 3) determined psychosocial predictors of changes in physical activity. The investigators hypothesized that there would be a monotonic decrease in physical activity and that psychosocial variables would predict changes in physical activity. The study population consisted of 189 sixth grade, mostly African-American, girls in Fort Bend Independent School District, Missouri City, Texas. The girls were measured for four and a half years, ages 11 or 12 at entry of the study. Anthropometry, sexual maturation, blood pressure, physical activity habits and psychosocial predictors were measured twice a year for a total of nine examinations. Data on dietary, smoking and drinking habits were collected annually. Activity patterns, psychosocial predictors and other habits were assessed by interviews and questionnaires. Sexual maturation was assessed by menarche and the Tanner stages. Skinfold and circumference measures determined body fatness and body fat distribution.
