function after dietary intervention aimed at weight loss in obese women with polycystic ovary syndrome. In obese women with polycystic ovary syndrome (PCOS), weight loss is recommended to combat endocrine and metabolic abnormalities and improve the likelihood of ovulation. While data to support an impact of weight loss on ovulatory function remain unconvincing, emerging evidence suggests that patients with greater endocrine disturbances may be less likely to experience reproductive benefit from dietary interventions. To that end, our objective was to assess the relationship between baseline androgen status and ovulatory function after weight loss in PCOS. Twenty obese subjects were recruited to a 3month hypocaloric dietary intervention. Markers of androgen status, including hirsutism, serum androgens, and ovarian morphology, were evaluated at baseline. Serial ultrasonography was used to determine ovulation during the intervention and subjects were categorized as “responders” (>1 ovulation) or “non-responders.” Differences in baseline androgen status between groups were assessed with t-tests or Wilcoxon rank-sum tests. Associations between baseline androgen status and ovulatory response were evaluated with logistic regression. Responders were distinguished from non-responders by lower hirsutism scores (p¼0.02), antral follicle counts (p¼0.03) and ovarian volumes (p¼0.01). Clinical (hirsutism: b: 0.33, p¼0.07) and sonographic (antral follicle count: b: 0.05, p¼0.09; ovarian volume: b: 0.45, p¼0.05) markers of androgen excess were associated with failure of the intervention to improve ovulatory function. Taken together, these findings suggest that patients with milder endocrine disturbances may be more likely to experience reproductive benefit from weight loss. Future analyses will elucidate the precise follicular events that lead to improved ovulatory function in PCOS.

Despite increased pubic health programming, rates of childhood overweight and obesity remain high in Michigan. It is well accepted that diet and physical activity play important roles in these conditions. This study aimed to improve diet and physical choices and self-efficacy among elementary and middle school students. This study utilized a 9 week educational intervention run through afterschool programming. Weekly lessons taught by dietetics and exercise science majors included nutrition education, hands-on food demonstrations and tastings, and physical activity. Lesson topics included food groups, label reading, hydration, and healthy activity. Students were recruited from four schools in a low income school district in Southeastern Michigan. Age, gender, and race were self-reported. Height and weight were measured pre- and post-intervention. Students completed a questionnaire to assess behaviors and self-efficacy regarding diet and physical activity pre- and postintervention. Forty-nine students participated and parental consent forms were obtained from 23. Of those with parental consent, 57% attended elementary school and 43% middle school. Following the program students reported an average decrease of 27 minutes spent watching TV during the week and of 59 minutes on the weekend. Students also reported increased active time at recess and increased self-efficacy with respect to eating the recommended number of daily servings of vegetables, dairy, and whole grains. Although not all measured behaviors improved, students benefited from education, exposure to new foods, and opportunities to participate in physical activity. Dietetics and exercise science majors gained valuable experience in the research process and in conducting community-level education.

Learning Outcome: The learner will describe the value of teaching kitchens in fitness centers. Introducing teaching kitchens to fitness centers is a practical approach to address two behaviors that can be modified to increase health and longevity. Purpose of this descriptive, mixed-methods study was to assess (1) fitness center client’s perspectives on having a teaching kitchen in the facility and (2) Registered Dietitians, specializing in wellness, perspectives on feasibility of these kitchens. Surveys for fitness center clients were conducted at an oncampus recreation center for five days at varying times in order to reach the most students, faculty, and staff. Qualitative data were gathered by interviewing dietitians in a structured format and coded for themes using axial coding. Quantitative data were entered into SPSS where descriptive analyses and frequencies were calculated. A total of 81 fitness center participants responded to the survey and four dietitians were interviewed. Most fitness center participants were interested in a teaching kitchen, specifically meal planning (56.8%), classes (49.4%), nutrition counseling (43.2%), culinary lessons (40.7%), and grocery store tour (38.3%). Dietitians indicated three potential benefits: community resource, hands-on approach for clients, and motivational tool. Potential barriers identified by dietitians included: costeffectiveness, bigger facility to accommodate, and safety regulations. Results of this study support placing a teaching kitchen inside a fitness center to help facilitate long-term success for clients. Diet and physical activity go hand in hand and clients desire nutrition knowledge as they start an exercise routine. Registered Dietitians can have an impact on wellness curriculum and collaborate with fitness professionals to help clients reach their health and wellness goals. Funding Disclosure: None
Learning Outcome: This study provides objective data on caregivers’ perceptions of their infants’ tolerance to infant formula. This assists in providing the healthcare professional information on commercially available infant formula. Background: Understanding caregiver perception of infant formula tolerance can help providers discuss feeding choices with parents. Methods: The objective of this double-blind, randomized crossover study was to assess stool consistency of infants fed two different commercially available infant formulas. Caregiver-perception of tolerance (spit-up, vomit, stool frequency, flatulence), mood, daily sleep duration and formula preference were evaluated. Exclusively formula-fed full-term infants were fed Test (100% whey, partially hydrolyzed, with prebiotics) and Control (intact cow’s milk protein with prebiotics) formulas for 2-week periods each. Caregivers kept daily tolerance records. Formula groups were compared using a paired t-test accounting for crossover design. Results: Demographics were similar among 41 subjects (mean age: 1.04 0.54 months). Infants had a higher proportion of soft stools (79.7 vs 70.0%, p¼0.0605) when consuming Test, reaching statistical significance during week 2 (86.5 vs 73.2%, p¼0.015). Subjects had significantly more liquid stools when on Control (19.0 vs 8.9%, p¼0.0014). Infants had a lower proportion of days with frequent spit-up (>5 times/day) when consuming Test (7.0 vs 13.0%, p¼0.056) which was significant in the first week of consumption (8.4 vs 14.8%, p¼0.039). There were no significant differences in secondary outcomes. For mood, caregivers stated subjects were ‘happy’ or ‘content’ the majority of the time on both formulas. Conclusion: There was a higher proportion of soft stools, and fewer days with frequent spit-up at different time points of Test formula consumption. This information is relevant when educating caregivers of formula-fed infants. Funding Disclosure: Nestle Nutrition
