TITLE: A HIGH PREVALENCE OF OVERWEIGHT AND OBESITY AMONG MEXICAN AMERICAN MEN AND WOMEN IN GUILFORD COUNTY, NORTH CAROLINA AUTHOR(S): L. Sanchez-Lugo, PhD, RD, LDN; D.G. Herr, PhD
LEARNING OUTCOME: To determine if serum albumin is more strongly correlated with inflammatory markers compared to nutritional markers in maintenance hemodialysis patients.
LEARNING OUTCOME: To describe the prevalence of overweight and obesity among Mexican Americans 21 years old or older in Guilford County, North Carolina.
TEXT: Abnormal serum albumin levels are commonly observed in hemodialysis patients. Whether the low serum albumin level is a reflection of true protein-energy malnutrition or resultant from an inflammatory process has not been determined. A sample of convenience was used to obtain forty four hemodialysis patients for participation in this study approved by the Hospital IRB. Serum levels of C-reactive protein, ferritin, sed rate, and fibrinogen were used as inflammatory markers and serum albumin, BMI, T. lymph, pre-albumin and protein catabolic rate (PCR) were used as nutritional markers. Descriptive statistics were used to analyze demographic variables. Pearson product correlation was used to determine the relationships between serum albumin and both inflammatory and nutritional marker variables. The level of significance was set at p⬍0.05. The mean age of participants was 62.3 ⫾ 11.5 years. Mean dry weight was 76 ⫾ 16.1 kg and the mean BMI was 24.2 ⫾ 4.77. Mean predialysis serum albumin was 3.34 ⫾ 0.45 mg/dl. Mean C-reactive protein was 1.69 ⫾ 2.2 mg/L. A significant correlation was observed between serum albumin and serum pre-albumin (p⬍0.001) as well as serum albumin and cholesterol (p⬍0.001). There were no significant relationships observed between serum albumin and any of the inflammatory markers. These results indicated that serum albumin was more strongly correlated with various nutritional markers rather than inflammatory markers in hemodialysis patients.
TEXT: Hispanics are the fastest growing minority group in the US, and the prevalence of obesity and diabetes is reaching epidemic proportions. Data related to dietary intake, anthropometrics, and demographic characteristics was collected from three hundred thirty five subjects (190 women and 145 men). Nutritional information was collected using a modified Block food frequency questionnaire (SWAN 10/95). The results are presented as the mean ⫾ the standard error of the mean. The average age was 30.8 ⫾0.8 (men) and 31.6 ⫾0.7 (women). The average body mass index (BMI) was 28.2 ⫾0.5 (men) and 29.5 ⫾0.4 (women). Sixty-two percent of men and 72 percent of women were overweight or obese according to BMI. The BMI range was from 19.2 to 56.9 (men) and 18.3 to 63.2 (women). These results show that the prevalence of overweight and obesity among these Mexican Americans surveyed are higher when compared with population-based studies (NHANESIII). The mean energy intake adjusted by age was 3370 ⫾496 kcal (men) and 2693 ⫾ 293 kcal (women). The intake of macronutrients as percent of energy intake adjusted by age was the following; for protein 16% for both genders, for fat 32% (men) and 31% (women), and for carbohydrates was 51% (men) and 53% (women). The intake of kcal and macronutrients adjusted by age varied according to different BMI strata. These results will lead to culturally relevant intervention studies related to nutrition, physical activity and behavior modification strategies in an attempt to reduce the prevalence of overweight and obesity.

LEARNING OUTCOME: To describe the intake of selected micronutrients in college tennis players’ diets. TEXT: Most micronutrient studies on athletes have used the former RDAs as reference standards. Few studies have compared micronutrient intakes in athletes to the more recent Dietary Reference Intakes (DRIs). Also, to our knowledge, this is the first study to examine the micronutrient intakes of collegiate tennis players. Nine men and four women from a Division I university completed three-day food records. The food records were analyzed using the Healthy Eating Index (HEI) and compared to the DRIs. Twenty-three percent of the athletes consumed less than 75% of the recommendations for calcium and 31% consumed less than 75% of the recommendations for folate. Fifty-four percent consumed less than 75% of the recommendations for vitamin E. Since the men were consuming 100% of the estimated kilocalories needed and the women were consuming 89% of their estimated need, we don’t think the findings are the result of underreporting intake. Comparing new dietary adequacy studies in athletes to prior studies is difficult because most past studies compared nutrient intake to the RDAs instead of the more recent DRIs. However, this study supports previous studies in which folate and calcium in athletes (especially women) were reported to be well below the RDAs. While our sample size is small, other studies of a similar nature have also had small sample sizes. However, since our sample size is small, only from one university, and because studies in this area are limited, more research is needed to determine if most college tennis players have similar micronutrient profiles.

LEARNING OUTCOME: To identify and quantify factors that influence food choices of college students. TEXT: Effective dietary modification depends on understanding factors that govern food choice; identifying factors important for specific population segments should allow development of targeted health promotion strategies. A multidimensional food-choice questionnaire has been validated for use within western urban populations. 217 college students rated 36-items on a 4-point scale in response to: “It is important to me that the food that I eat on a typical day. . ..” Participants were predominantly female (71%), Caucasian (88%) and 18 –20 years old (60%); 54% were unemployed and 2.8% followed special diets. Responses were subjected to exploratory factor analysis (SAS, version 8.2). The principal factor method extracted factors subsequently subjected to varimax rotation. Items not loading on a single factor were discarded. The Scree test suggested 7 meaningful factors that explained 50.7% of the total variance. Factors 1–7 explained 9.6, 10.0, 7.6, 9.5, 7.2, 3.8 and 3.0% of the total variance, respectively. Factor 1 (8 statements) related to diet and health. Factor 2 (5 items) related to mood. Factor 3 (3 items) related to weight control. Factor 4 (4 items) dealt with convenience and time. Factor 5 (3 items) reflected costs. Factor 6 (3 statements) related to familiarity of food. Factor 7 (2 items) related to sensory characteristics. Cronbach’s alpha of the multi-item scales ranged from 0.62 to 0.90, suggesting internal reliability. A dietary modification program employing a multi-factor approach is suggested by the percentage variance explained by these individual factors. Identifying other influential factors may allow development of a more streamlined message for this audience.
