Injuries and Risk Factors in an 18-Day Marine Winter Mountain Training Exercise

This study determined the incidence of and risk factors for injuries among 356 Marines during a winter mountain training exercise. Marines received a podiatry screening and completed a questionnaire on race, education, tobacco use, height, weight, and fitness (4.8-km run, sit-ups, pull-ups). Forty-five Marines (12.6%) reported at least one injury each, 68.9% of which were traumatic injuries. Total injuries resulted in 114 days of limited duty time. A final foot examination (N = 141) revealed 118 injuries (82.2% blisters and abrasions, 11.9% frostnip). White ethnicity was a risk factor for overall injuries, and forefoot varus alignment was a risk factor for traumatic injuries. Lower education and rank and smokeless tobacco use were associated with foot injuries. The Marine ski-march leather boot and smoking were related to foot cold injuries. Military winter training is associated with injuries and lost training time. Risk factors were identified, suggesting that these injuries may be preventable.

Childhood obesity: a risk factor for traumatic injuries to anterior teeth.

The relationship between obesity and traumatic dental injuries was evaluated in a study population of 938 6- to 11-year-old schoolchildren from Rome, Italy, and it was suggested by the lifestyle and the physical activity of obese children, which, according to many authors, is different from the lifestyle of other children. The subjects were examined at school: presence and type of dental injury, overjet, incisor protrusion, upper lip incompetence and presence of obesity were recorded. Trauma predisposition was evaluated with a questionnaire investigating the behaviour which may predispose to impacts. Six out of eight questions in this questionnaire concerned the children's lifestyle and the trauma predisposition score was therefore also considered an estimate of lifestyle and physical activity. The dental injury prevalence of the study population was 21.3% and obesity prevalence was 11.4%. Of the obese children 30.8% had dental injuries vs. only 20.0% of non-obese subjects (P = 0.007). Obese children had only enamel and enamel-dentine fractures and the main reported trauma cause was indoor play; conversely, lean children also had other types of injuries and the most frequently reported cause was outdoor play. The main predisposing factors significantly affecting the probability of dental injury, evaluated with multiple logistic regression, were upper lip uncoverage (OR: 1.23; P = 0.02), overjet larger than 3 mm (OR: 1.68; P = 0.001) and obesity (OR: 1.45; P = 0.01). Surprisingly, trauma predisposition was a protective factor (OR: 0.50; P = 0.00001). The results of this study were explained by the significant inverse correlation between obesity and trauma-predisposing behaviour, thus suggesting that subjects frequently playing sports and lively games were not only less obese but also more skillful and, for this reason, less prone to trauma when they fell or sustained impacts.

Injuries on the fireground: risk factors for traumatic injuries among professional fire fighters.

This case-control study within a metropolitan fire department evaluated the effect of self-contained breathing apparatus (SCBA) and other risk factors on three types of injury at the scene of a fire (smoke inhalation, burns, and falls). Data on 75 injured fire fighters and 144 controls came from telephone interviews and department records. The two sets of uninjured fire-fighter controls were matched to cases on incident (n = 72) or on job position and fire type and size (n = 72). Smoke inhalation cases were not significantly different from controls in SCBA use, cigarette smoking, previous fires in the shift, or injury history. Jobs with high risk of burns included nozzle operator, engine officer, and forcible-entry person in first-due companies (OR = 20.1). Other risk factors for burns were: basement origin of fire (OR = 10.2); prior fire-fighting training outside the present department (same fire: OR = 11.2; similar fire: OR = 3.9); and on-duty injury in the prior 12 months (same fire: OR = 4.3; similar fire: OR = 3.5). When other risk factors were considered, consistent SCBA use was associated with falls (same fire: OR = 11.8; similar fire: OR = 4.3) but not with burns. Risk of falls also was elevated among members of truck companies (OR = 17.7) and fire fighters without children (same fire: OR = 8.4; similar fire: OR = 7.4). On-duty injury in the past 12 months was associated with falls when one compared cases with similar-fire controls (OR = 5.5), but not with controls attending the same fire. Neither age nor experience was related to injury in this population.
