TITLE: LIFESTYLE INTERVENTION FOR THE POLYCYSTIC OVARY SYNDROME PATIENT

Brenda Bryan,RD,LDN AUTHOR:

LEARNING OUTCOME: The healthcare professional and ultimately the Polycystic Ovary Syndrome patient will be able to recognize and implement the lifestyle changes that are necessary to treat the

disorder.

ABSTRACT TEXT: Polycystic ovary syndrome (PCOS), while being the most common hormonal problem affecting women of reproductive age, is often both unrecognized and undertreated. Five to ten percent of all women of reproductiv e age have some characteristic of PCOS. Obesity, hirsutism, and lack of timely ovulation are the most common signs of PCOS. Patients may also exhibit hypertension and abnormal lipid, insulin, and glucose levels. Weight gain is a common occurrence and one of the reasons that treatment is sought. Women with PCOS need to be educated about the health implications of the syndrome. The unique insulin resistance seen in women with PCOS increases the risk of cardiovascular disease. Increased insulin levels also promote excess energy storage, which in turn results in weight gain. The patients are often instructed by their physicians to lose weight, but are given very little guidance on safe dieting practices. A 16 week lifestyle intervention program wes developed. The program emphasized healthy lifestyle changes, but not rapid weight loss. Expert guest speakers from nutrition, exercise, and psychology were incorporated into the program. Interactive cooking and exercise sessions were included along with grocery store and restaurant field trips.

TITLE: IDEALIZED FEMALE BODY IMAGES 1N PRINT MEDIA TARGETED TO MEN: A LONGITUDINAL ANALYSIS OF PLAYBOY MAGAZINE CENTERFOLD MODELS AUTHORS: Carol Byrd-Bredbenner, Ph.D., R.D., F.A.D.A. and Jessiea Murray, Rutgers University. LEARNING OUTCOME: Describe the temporal changes in anthropometric measurements (i.e., bust, waist, and hip circumferences, weight, and height) of Playboy magazine centerfold models from 1954 to 2000. ABSTRACT TEXT: There is growing concern over the idealized female body images portrayed in the media because evidence indicates that these images may foster dissatisfaction with body shape and weight among women. Indeed, negative body images are linked to excessive dieting, eating disorders, and other problems. Previous research has tended to treat the idealized female body image in the media as a homogenous image without regard to the audience to whom the media is directed. Thus, the purpose of this study was to examine the idealized female body image shown in media targeted to men over the last half century. Anthropometric measurements were compiled for a single representative centerfold model for each year Playboy magazine has been published (i.e., 1954 to 2000) (n=47). For every year a "Playmate of the Year" (PMOY) was selected, she was used as the representative model. A model was randomly selected to represent the 5 years lacking a PMOY. Height steadily increased from a mean of 64.6+1.4"SD in the 1950s to 68.3+2.7"SD in the 1990s. Weight in pounds also rose steadily from 114.3_+5.0SD in the 1950s to 123.4+11. ISD in the 1990s. Simple linear regression revealed a significant time-dependent increase in height (13=0.0001) and weight (p=0.01). However, the rate of height increase exceeded the expected rate of weight increase, thus a time-dependent significant decline in Body Mass Index (BMI) occurred (13=0.0058). Only 11% of the models had a normal BMI (i.e., 20 to 25); the remainder were underweight with 43% dipping below the WHO criterion for undernourished (BMI<18.5). Three (6%) had BMIs so low that they met the American Psychiatric Association's BMI criterion for Anorexia Nervosa (517.5). To examine changes in body shape (i.e., hourglass vs. tubular), a curvaceousness index [height/(bust-waist)+(hips-waist)] was computed. No changes were noted in body shape over time with bust-waist-hip circumference means, in inches, for all models being 35.7+1.3SD - 23.4+1.3SD - 35.2+1.2SD, respectively, i.e., hourglass shape. The idealized female body image depicted in Playboy magazine is not reflective of the actual or recommended U.S. female body size. This contrast raises issues concerning the impact of these images on men's expectations of women. CONFLICT OF INTEREST: None

TITLE: FACTORS THAT INFLUENCE WOMEN'S SUPPLEMENT INTAKE

AUTHOR(S): M. Contreras, MS,MD, G.E. Gates, Phi), RD/LD, Oklahoma State University, Stillwater OK, 74078

LEARNING OUTCOME: To determine influences on supplement intake in young women.

ABSTRACT TEXT: The purpose of this study was to determine the factors that influence supplement consumption by young women. A questionnaire was mailed to a random sample of 2,000 women (18-44 years old) in Oklahoma. Response rate was 33%. Mean age was 37 + 6 years old. Fifty percent of the respondents reported taking a vitamin/mineral supplement on a regular basis, and only 15% never took supplements. Most women who took supplements chose multivitarrfin preparations (79%). Women who took supplements regularly were more likely to exercise, weigh less, be more educated, and consume a normal diet (p<.05). Most (88%) said they would be willing to take supplements daily. Women who took supplements regularly were more likely to believe in the benefits of supplements (e.g., supplements are good for my health) and were less likely to agree with barriers to supplement intake (e.g., it is difficult to swallow pills) (p<.001). Using logistic regression analysis, several variables were associated with supplement use: scores of benefits and barriers of supplement use, age and diet. These variables correctly classified 84% of women's supplement use. When women need to consume supplements such as folic acid to prevent neural tube defects, it is important for nutrition educators to address these factors that influence their willingness to take supplements. Funding was provided by the Oklahoma Center for the Advancement of Science and Technology.

TITLE: CONSUMER AND RESEARCH APPLICATIONS FOR UNITED STATES DEPARTMENT OF AGRICULTURE'S FOOD MODEL BOOKLET

LEARNING OUTCOME: To increase awareness of a new tool for portion size and diet evaluation.

A B S T R A C T TEXT:

A Food Model Booklet consisting of 32 two-dimensional drawings of typical food vessels, abstract shapes, and geometrically-based models was developed for use in 24-hcur dietary recalls in national food intake surveys. An accuracy test of the models was conducted comparing food portions estimated by 264 participants with actual volumes of 17 popular foods. Repeated measures analysis demonstrated that the models performed better in general than conventional three-dimensional models (measuring cups, spoons, and ruler). Healthful diets are a goal for many in America but identifying reasonable portion sizes is a challenge. Therefore, a companion piece containing volumes of the models and values of selected nutrients of frequently consumed foods will accompany the booklet. Educators, dietitians, and consumers will be able to estimate portion sizes of foods with the Food Model Booklet and then determine the nutrient values of those portions. The new Food Model Booklet may serve as an evaluative tool for diets as well as for comparisons of foods and different-sized portions.
