Impact of today's media on university student's body image in Pakistan: a conservative, developing country's perspective

<p>Abstract</p> <p>Background</p> <p>Living in a world greatly controlled by mass media makes it impossible to escape its pervading influence. As media in Pakistan has been free in the true sense of the word for only a few years, its impact on individuals is yet to be assessed. Our study aims to be the first to look at the effect media has on the body image of university students in a conservative, developing country like Pakistan. Also, we introduced the novel concept of body image dissatisfaction as being both negative and positive.</p> <p>Methods</p> <p>A cross-sectional study was conducted among 7 private universities over a period of two weeks in the city of Karachi, Pakistan's largest and most populous city. Convenience sampling was used to select both male and female undergraduate students aged between 18 and 25 and a sample size of 783 was calculated.</p> <p>Results</p> <p>Of the 784 final respondents, 376 (48%) were males and 408 (52%) females. The mean age of males was 20.77 (+/- 1.85) years and females was 20.38 (+/- 1.63) years. Out of these, 358 (45.6%) respondents had a positive BID (body image dissatisfaction) score while 426 (54.4%) had a negative BID score. Of the respondents who had positive BID scores, 93 (24.7%) were male and 265 (65.0%) were female. Of the respondents with a negative BID score, 283 (75.3%) were male and 143 (35.0%) were female. The results for BID vs. media exposure were similar in both high and low peer pressure groups. Low media exposure meant positive BID scores and vice versa in both groups (p < 0.0001) showing a statistically significant association between high media exposure and negative body image dissatisfaction. Finally, we looked at the association between gender and image dissatisfaction. Again a statistically significant association was found between positive body image dissatisfaction and female gender and negative body image dissatisfaction and male gender (p < 0.0001).</p> <p>Conclusions</p> <p>Our study confirmed the tendency of the media to have an overall negative effect on individuals' body image. A striking feature of our study, however, was the finding that negative body image dissatisfaction was found to be more prevalent in males as compared to females. Likewise, positive BID scores were more prevalent amongst females.</p

Portrayals of Overweight and Obese Individuals on Commercial Television

Objectives. This study examined the distribution and individual characteristics of body types on prime-time television. Methods. Five episodes of each of the 10 top-rated prime-time fictional programs on 6 broadcast networks during the 1999–2000 season were quantitatively analyzed. Results. Of 1018 major television characters, 14% of females and 24% of males were overweight or obese, less than half their percentages in the general population. Overweight and obese females were less likely to be considered attractive, to interact with romantic partners, or to display physical affection. Overweight and obese males were less likely to interact with romantic partners and friends or to talk about dating and were more likely to be shown eating. Conclusions. Overweight and obese television characters are associated with specific negative characteristics

Children With Heart Murmurs: Can Ventricular Septal Defect Be Diagnosed Reliably Without an Echocardiogram?

AbstractObjectives. This study was undertaken to determine the accuracy of expert examination for ventricular septal defect (VSD) among children with a heart murmur.Background. Because the frequency and nature of errors that might be made by reliance solely on expert examination for diagnosis of VSD are speculative, the role of echocardiography in such diagnosis is controversial.Methods. Two hundred eighty-seven consecutive previously unevaluated pediatric subjects were enrolled in the study. For each child, the pediatric cardiologists prospectively recorded a working diagnosis and their level of confidence in the diagnosis, categorizing any VSD diagnosed as small or moderate to large. After echocardiography, VSDs were subcategorized by location and requirement for treatment as minor, intermediate or major. Receiver-operating characteristic (ROC) curves described the accuracy of the clinical examination.Results. Seventy-three subjects had a VSD (minor in 52, intermediate in 10 and major in 11). ROC areas (1.0 = perfect discrimination, 0.5 = indiscriminate) were minor VSD 0.92 ± 0.02 and major/intermediate VSD 0.69 ± 0.07 (p = 0.0016). Four of 52 minor VSDs were not identified at any level of suspicion; the clinical diagnoses were moderate to large VSD in two patients and atrial septal defect and unlimited differential diagnosis in one patient each. Fourteen of 235 patients without a minor VSD were believed with confidence to have a small VSD, but the final diagnosis was intermediate VSD in 4, innocent murmur in 3, major VSD in 2, pulmonary stenosis in 2 and subaortic membrane, atrial septal defect and mitral regurgitation in 1 patient each.Conclusions. Almost all minor VSDs are recognized without echocardiography; however, errors can occur even when an expert examiner is confident. Clinical recognition of an intermediate or major VSD is less accurate than clinical recognition of a minor VSD. Failure to distinguish VSDs of major or intermediate importance from minor VSDs is a weakness of the expert clinical examination.(J Am Coll Cardiol 1997;30:243–6
