Self-reported smoking and musculoskeletal overuse injury among male and female U.S. Marine Corps recruits.

The association between self-reported smoking and overuse injury in a cohort of young men (n = 900) and women (n = 597) undergoing 12 weeks of standardized military instruction, after adjustment for physical activity, health history, and incoming fitness tests was examined. The outcome includes all International Classification of Diseases, 9th Revision codes related to injuries resulting from cumulative microtrauma (overuse injuries). The short survey asked about the subject's demographics, smoking habits, prior injuries sustained, physical activity level, self-perceived fitness, and (for women) menstrual history.

Sleep patterns before, during, and after deployment to Iraq and Afghanistan.

Study Objectives: To determine the associations between deployment in support of the wars in Iraq and Afghanistan and sleep quantity and quality.

Design: Longitudinal cohort study

Setting: The Millennium Cohort Study survey is administered via a secure website or US mail.

Participants: Data were from 41,225 Millennium Cohort members who completed baseline (2001-2003) and follow-up (2004-2006) surveys.

Physical activity and public health in older adults: recommendation from the American College of Sports Medicine and the American Heart Association.

Objective: To issue a recommendation on the types and amounts of physical activity needed to improve and maintain health in older adults.

Participants: A panel of scientists with expertise in public health, behavioral science, epidemiology, exercise science, medicine, and gerontology.

Evidence: The expert panel reviewed existing consensus statements and relevant evidence from primary research articles and reviews of the literature.

Influence of physical activity-related joint stress on the risk of self-reported hip/knee osteoarthritis: a new method to quantify physical activity.

Background: The relationship between physical activity (PA) and the development of hip/knee osteoarthritis (OA) has not been clearly defined. The purpose of this study was to develop a method to quantify PA-related joint stress and to assess its influence on the risk of hip/knee OA.

Methods: Participants in a large longitudinal study, without knee/hip OA (n = 5284), were asked about their PA participation in 1986.

Epidemiology of musculoskeletal injuries among sedentary and physically active adults.

Purpose: This study describes the types and frequencies of musculoskeletal injuries among a cohort of adults with above average activity levels who were enrolled in the Aerobics Center Longitudinal Study (Dallas, TX).

Methods: Participants were adults aged 20-85 yr who completed a baseline clinical examination (1970-1982) and returned a mailed follow-up survey in 1986. Participants (5,028 men, 1,285 women) were measured for aerobic fitness, height, and body weight during the baseline examination.

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.
