Predictors of lower extremity injury among recreationally active adults.

OBJECTIVE: To identify gender-specific predictors of lower extremity injury among a sample of adults engaging in running, walking, or jogging (RWJ) for exercise. DESIGN: Prospective cohort study. SETTING: Cooper Clinic Preventive Medicine Center, Dallas, Texas. PARTICIPANTS: Participants were 2,481 men and 609 women who underwent a physical examination between 1970 and 1981 and returned a follow-up survey in 1986. Predictor variables measured at baseline included height, weight, and cardiorespiratory fitness. At follow-up, participants recalled information about musculoskeletal injuries, physical activity levels, and other predictors for lower extremity injury over two time periods, 5 years and 12 months. MAIN OUTCOME MEASURES: An injury was defined as any self-reported lower extremity injury that required a consultation with a physician. Cox proportional hazards regression (HR) was used to predict the probability of lower extremity injury for the 5-year recall period, and unconditional logistic regression was used for the 12-month recall period. RESULTS: Among men, previous lower extremity injury was the strongest predictor of lower extremity injury (HR = 1.93-2.09), regardless of recall period. Among women, RWJ mileage >20 miles/wk was the strongest predictor for the 5-year period (HR = 2.08), and previous lower extremity injury was the strongest predictor for the 12-month period (HR = 2.81). CONCLUSIONS: For healthy adults, walking at a brisk pace for 10-20 miles per week accumulates adequate moderate-intensity physical activity to meet national recommendations while minimizing the risk for musculoskeletal lower extremity injury. Clinicians may use this information to provide appropriate injury prevention counseling to their active patients.

Clonal populations of thermotolerant Enterobacteriaceae in recreational water and their potential interference with fecal Escherichia coli counts.

Bacterial strains were isolated from beach water samples using the original Environmental Protection Agency method for Escherichia coli enumeration and analyzed by pulsed-field gel electrophoresis (PFGE). Identical PFGE patterns were found for numerous isolates from 4 of the 9 days sampled, suggesting environmental replication. 16S rRNA gene sequencing, API 20E biochemical testing, and the absence of beta-glucuronidase activity revealed that these clonal isolates were Klebsiella, Citrobacter, and Enterobacter spp. In contrast, 82% of the nonclonal isolates from water samples were confirmed to be E. coli, and 16% were identified as other fecal coliforms. These nonclonal isolates produced a diverse range of PFGE patterns similar to those of isolates obtained directly from untreated sewage and gull droppings. beta-Glucuronidase activity was critical in distinguishing E. coli from other fecal coliforms, particularly for the clonal isolates. These findings demonstrate that E. coli is a better indicator of fecal pollution than fecal coliforms, which may replicate in the environment and falsely elevate indicator organism levels.

Sports and recreational injuries: regional rural injury study-II: impact on agricultural households and operations.

OBJECTIVES: To identify the incidence, severity, and potential risk factors for sports/recreational injuries incurred by children and adults in a five state, rural, Midwest, agricultural household population. METHODS: Computer assisted telephone interviews that included questions about all injuries were completed for eligible, participating households for 1999; 16,538 people participated, including 8488 children less than 20 years of age. Rates and 95% confidence intervals were calculated, and causal models guided multivariate models. RESULTS: Of a total of 2586 injuries, 1301 (50%) were not related to agricultural activity. Among these, 733 (28%) were associated with sports/recreational activities including multiple person sports (64%), general play activities (19%), and single person sports (14%). The overall rate was 46.4 injury events per 1000 persons per year. Rates for children were 99.4 for boys and 64.3 for girls. For adults (aged 20 and above), rates were 11.9 for men and 4.8 for women. For children, 93% received health care, 44% were restricted for seven or more days, and 18% lost agricultural work time of seven or more days; the respective proportions for adults were 88%, 45%, and 17%. Multivariate analysis for children showed increased risks for Nebraska residents, males, and those 10-14 or 15-19 years. For adults, increased risks were identified for males and those 20-24 years; decreased risks were observed for Nebraska residents and those 45-54 years. CONCLUSIONS: Sports/recreational activities are an important source of injury with relevant consequences for this population, including significant restricted daily activity and lost agricultural work time. Key findings provide a basis for further study to address these burdens.
