Predisposing Risk Factors for Stress Fractures in Collegiate Cross-Country Runners.

ABSTRACT: Giffin, KL, Knight, KB, Bass, MA, and Valliant, MW. Predisposing risk factors and stress fractures in collegiate cross-country runners. J Strength Cond Res 35(1): 227-232, 2021-The purpose of this study was to explore factors associated with increased stress fractures in collegiate cross-country runners. Subjects in this study were 42 male and female cross-country runners at a Division I university. Each athlete completed a questionnaire regarding smoking status, vitamin/mineral intake, previous stress fracture history, birth control usage, menstrual status, and demographic information. Nutritional assessment using a 3-day food record and measurements of whole body, lumbar spine, and hip bone mineral densities (BMDs) were also conducted on each athlete. Results indicated that 40% of the female and 35% of the male runners reported a history of stress fracture, and that all of them did not meet the recommended daily energy intake or adequate intakes for calcium or vitamin D required for their amount of training. Two-tailed t-test found statistically higher incidences of lumbar spine BMD in male and female runners whose daily calcium and vitamin D intakes were below minimum requirements as well as for women whose caloric intake was below the required level. When data on the lumbar spine was evaluated, 31% of subjects (31.8% of the male and 30% of the female runners) were identified as having osteopenia and 4.8% with osteoporosis. Results warrant a need for future longitudinal studies.

Physical activity in the Families in Transformation (FIT) weight management program for children.

Background: The purpose was to determine if an 8-week nutrition education and exercise program for families could influence health and fitness parameters, and retention of nutrition knowledge. Methods: Eighteen children (mean age: 10.52 ± 1.26 year; 50% boys, 50% girls; 56% white, 25% black, 19% multiracial) participated in the Families in Transformation (FIT) program. Preand post-study anthropocentric, blood pressure, fitness, and nutrition knowledge data was collected. Results: Diastolic blood pressure decreased for the total group (66.63 ± 8.81 to 63.75 ± 11.81mm Hg). Significant (P < 0.05) increases were seen for the group for push-ups (14.31 ± 7.62 to 19.63 ± 6.62) and chair squats (30.50 ± 10.21 to 34.44 ± 7.39). The reinforcing physical activity group performed significantly better on nutrition knowledge quizzes. Conclusion: Although, body mass index (BMI) z-scores did not change, there was a decrease in diastolic blood pressure, increase in fitness parameters, and increased retention of nutrition knowledge.

Association between athletic participation and the risk of eating disorder and body dissatisfaction in college students.

OBJECTIVE: Given that females exhibit a greater prevalence of eating disorders, there is of yet no conclusive evidence whether participation in college athletics exacerbates eating disorders or body shape dissatisfaction. This study assessed how gender and participation in collegiate athletics are associated with increased risk for disordered eating attitudes and body shape concerns in college students. METHODS: This study used a cross-sectional research design. A total of 302 students at a Southern US university fully completed the eating attitudes test and the body shape questionnaire during class time or team meetings. Logistic regression was conducted to determine risk differentials for each group. RESULTS: Of 302 students, 65.6% were females and 63.2% were non-athletes. Athletic status was significant as well but became slightly less so with adjustment (unadjusted at OR = 3.14, P < 0.001 vs. adjusted OR = 3.22, P < 0.001). Moreover, it was found that that non-athletic female students are slightly more at risk for disordered eating and significantly more dissatisfied with their body shape (OR = 5.95, P < 0.001). CONCLUSIONS: Although there seems to still be many unresolved issues regarding eating disorders, one thing is clear females are at higher risk, and it remains a significant challenge to college health services. College health practitioners should be made aware of the significant effect stress has on freshman in particular.

Pertinence of the recent school-based nutrition interventions targeting fruit and vegetable consumption in the United States:a systematic review.

BACKGROUND: Schools are the major locations for implementing children's dietary behavior related educational or interventional programs. Recently, there has been an increase in school-based nutrition interventions. The objective of this systematic review was to overview the evidence for the effectiveness of school-based nutrition intervention on fruit and vegetable consumption. METHODS: PubMed was used to search for articles on school-based nutrition interventions that measured students' fruit and vegetable consumption. Our search yielded 238 articles.The article was included if published in a peer-reviewed journal, written in English language,administered in the United States, and conducted among a population-based sample of children in Kindergarten through eighth grade. A total of 14 publications met the inclusion criteria. RESULTS: Eight articles successfully showed the positive effect on increasing fruit and or vegetable consumption while the other six did not. Several factors, including (but not limited to) intervention duration, type of theory used, style of intervention leadership, and positively affecting antecedents of fruit and vegetable consumption were compared; however, no dominant factor was found to be shared among the studies with significant findings. Given that the criteria for selection were high, the lack of consistency between interventions and positive outcomes was surprising. CONCLUSION: With high levels of scrutiny and budget constraints on school nutrition, it is imperative that more research be conducted to identify the effective intervention components.

Improving breast diagnostic services with a Rapid Access Diagnostic and Support (RADS) program.

BACKGROUND: The diagnostic phase of care is an anxiety-provoking and stressful experience for the potential breast cancer patient. A multidisciplinary team of breast cancer specialists embarked on a new initiative to pilot a Rapid Diagnosis and Support (RADS) Clinic to coordinate the diagnostic workup and nursing support for patients with a high probability of breast cancer. METHODS: Consecutive patients with an initial diagnostic imaging classified as BI-RADS 5 were invited to participate in this 1-year prospective study. Coordination of diagnostic imaging workup and nursing support were provided by a nurse navigator. Wait times were evaluated at several intervals of care. Satisfaction surveys were given to study participants and compared to scores from patients who did not go through RADS clinic. RESULTS: A total of 211 patients participated in the RADS clinic. Biopsy wait times improved from a mean of 7 to 3 days (p < 0.001), pathology from 3.9 to 3.3 days (p < 0.001), surgical consultation from 16.1 to 5.9 days (p < 0.001), and operative wait times from 31.5 to 24.1 days (p = 0.042). There was a 95.3 % satisfaction rate with the RADS clinic with significantly improvement in patients' sense of an understanding of the treatment plan (p = 0.031), timeliness of tests (p = 0.045), and timeliness of results (p = 0.0419). CONCLUSIONS: The RADS clinic significantly improved diagnostic wait times and satisfaction scores for patients with a high probability of diagnosis of breast cancer and can serve as an innovative service delivery model for other breast care centers.
