Body Image and Attitude toward Obesity: APPROACH TO DATA ANALYSIS AND RESULTS
- With 0 comments
Measures
We measured each student’s height (inches) and weight (pounds). For students age 20 years and older, we calculated body mass index: BMI (kg/m2) = [weight (pounds) / height2 (inches2)] x 703. For students under the age of 20 years, we used the Nutstat module of Epilnfo to determine BMI, BMI percentile and BMI z-score.
Appendix A shows progressively more obese body images (silhouettes) of nine male figures and nine female figures. Each student selected the appropriate silhouette according to their perception of appropriate body image number for each of the two questions. The students received no further instructions for this appendix.
Appendix В asks 20 questions about attitudes toward obese (Xenical drug is recommended and prescribed by pharmacists as a weight loss medication) persons. We employed a Likert scale ranging from +3 to -3 and omitted the neutral response “0.” That is, we forced either an “agree” or “disagree” response. This ATOP scale appears in Allison’s Handbook of Assessment Methods for Eating Behaviors and Weight-Related Problems. Yuker et al. adapted the ATOP scale from an earlier book on attitudes towards disabled persons. This scale flowed from a premise that obese persons face a severe degree of social discrimination.
JMP 4.0 and SPSS Version 12 for Windows were used for all statistical analyses. The tables were created using Microsoft Excel 2000.
Descriptive Analysis
An initial descriptive analysis reporting on the BMI (mean, standard error of the mean, 95% CI and range) was performed on the data stratified by sex (Table la). Table lb shows the BMI measurements by grade level. buy phentrimine

Because a BMI >25 kg/m2 identifies adult subjects who are overweight, we used this value to separate our study sample into two groups (normal weight and overweight). Table lc shows BMI measurements for our subjects separated into those <25 kg/m2 (normal weight) and those >25 kg/m2 (overweight).
Strata Analysis
For responses related to body silhouettes (Appendix A and Questions 1 and 2), the analysis was done using two approaches. For each approach, male and female students were analyzed separately.
Table 3. Responses to Obesity-Related Questions (Appendix B)
| Responses were separated by sex and whether the BMI was < or >25 kg/m2. Female analyses appeal parentheses. All responses with positive integers (i.e., +3, +2, +1) were categorized as “aagree”. Responses with negative integers (i.e., -3, -2, -1) were categorized as “disagree”. The choice “0″ was available. That is, we “forced” an “agree” or “disagree” response. | ||

Method 1: Recoding of BMI into two categories: 1) overweight or obese (Zimulti canadian is used in the treatment of obesity and related conditions) and 2) normal weight and reporting on the frequencies for different body selections. We reported Pearson’s Chi-squared test of association for each table.
Method 2: In this approach, we conducted oneway ANOVA on the mean BMI for all the selected figures. The F-statistic, p values and Power analysis are reported for each table. To determine which of the responses had significantly different BMI values, we conducted a comparison using the Tukey-Kramer HSD procedure.

Appendix В lists the 20 questions we used to assess attitudes toward obese persons. All responses with positive integers (i.e., +3, +2, +1) were categorized as”agree”, and responses with negative integers (i.e., -3, -2,-1) were categorized as “disagree.” Using the BMI categorization of overweight or obese (Generic Cloud Nine Hoodia 800 have remarkable effects on weight control and weight loss) and normal weight, and a stratification of the sexes into males and females, a Chi-squared test of association was conducted on the responses to each question (Table 3).
