Item A Path Analysis of Body Mass Index, Body Image, and Unhealthy Dietary Behavior as Contributors to Suicidal Behavior in Female Adolescents(2004-05-01) Rorie, Michele Taylor; Balcazar, Hector; Lurie, Sue; Rene, Antonio A.Rorie, Michele Taylor, A Path Analysis of Body Mass Index, Body Image and Unhealthy Dietary Behavior as Contributors to Suicidal Behavior in Female Adolescents. Doctor of Public Health (Social and Behavioral Sciences), May 2004, 120 pp., 17 tables, 6 illustrations, references, 106 titles. Objectives- This study examined the pattern and magnitude of relationships between body mass index, body image, unhealthy dietary behaviors, and suicidal behavior among a sample of White, African American, and Hispanic adolescent females. Methods-This study employed secondary analysis of the 2001 Youth Risk Behavior Survey public-use dataset to provide quantitative estimates of the causal connections between body mass index, body image, dietary behaviors, and suicidal behavior. A sample (n=5,218) of White, African American, and Hispanic adolescent females aged 14-17 were selected for analysis. This cross-sectional study involved public high school students in grades 9-12. The variables/constructs BMI, Body Image, and Dietary Behavior were examined using a path analysis to determine the magnitude of effects on Suicidal Behavior in adolescent females. Results- The path coefficients were obtained for the path model using multiple regression equations, which took direct and indirect effects into account. The Female Adolescent Model (n= 5,218) yielded an R2 = .27. This meant that 27% of the variance in Suicidal Behavior was explained by BMI, Body Image, and Dietary Behavior. When race/ethnicity was analyzed separately, different values were observed. The White Adolescent Female Model (n=2,768) had an R2=.32. The Black or African American Model (n=1,206) had an R2=.23, and the Hispanic or Latino Model (n=1,224) had an R2=.27. Conclusion- The basic state of what is an actual fact about a person (i.e. weight) does not cause an increase of harmful or destructive behavior. The person’s beliefs drive intention as it was demonstrated through the immergence of significant indirect pathways from BMI through Body Image and Dietary Behavior to Suicidal Behavior. The path analyses for the three racial groups suggest that there are varying degrees of influence among BMI, Body Image, Dietary Behaviors, and Suicidal Behaviors.Item Promotores de Salud of North Texas: Impact of Health Education Intervention on the Change of Blood Pressure and Body Mass Index in Adult Participants in Dreams Project 1.(2008-05-01) Arslanagic, Enisa; Robert GracyArslanagic,Enisa, MD,CCRC., Promotores de Salud of North Texas: Impact of Health Education Intervention on the Change of Blood Pressure and Body Mass Index in Adult Participants in Dreams Project 1. Master of Public Health (Community Health), May 2008, 46 pp., 3 tables, references, 51 titles. The prevalence of obesity among Mexican Americans has been increasing over the past decade, and is associated with hypertension and diabetes. Secondary data from DREAMS study were used to evaluate whether behavioral intervention on diet and physical activity using promotores de salud model significantly reduced blood pressure and body mass index among adult participants. Results showed significant changes in systolic blood pressure after the trial within intervention and control group, without significant difference in changes of blood pressure and body mass index after the trial between groups. These findings suggest that more comprehensive programs are needed to better understand Hispanic population's health behavior.Item Use of Body Mass Index as a Predictor of Health Status in Firefighters(2002-05-01) Theurer, Wesley M.; Rene, Antonio A.; Clark, SharonTheurer, Wesley M., Use of Body Mass Index as a Predictor of Health Status in Firefighters. Master of Public Health (DO/MPH), May, 2002, 28 pp., 3 tables, 29 References. This study evaluated the usefulness of BMI as a screening tool for health parameters and duty fitness among firefighters. Our cohort consisted of 218 active firefighters between the ages of 18 and 58 (men 33.5 ±8.6). Two major BMI categorization methods were used: standard [low (30)] and obesity [(normal([less than] 25), overweight(≥25 [less than] 30), obese(≥30 [less than] 39), morbidly obese ≥39)] The mean BMI was 28.8 (±4.5). Standard categorization revealed that nearly 60% had medium or high BMI's; obesity categorization showed 80.7% to be overweight, obese, or morbidly obese. Statistically significant, adverse relationships between BMI and each of the following were found: systolic and diastolic blood pressure, VO2max, METS, and total cholesterol. Inconsistent or statistically insignificant relations were found between BMI and HDL, Chol/HDL ratios, Triglycerides, FVC, and FEV1sec. Tobacco use and participation in an exercise program is also reported. BMI continues to prove useful as a screening tool and may be useful in identifying individual firefighters for health and fitness intervention measures.
