ABSTRACT
BACKGROUND: Wild game hunting is a popular activity in many regions of the United States. Recently, the presence of lead fragments in wild game meat, presumably from the bullets or shot used for hunting, has raised concerns about health risks from meat consumption. OBJECTIVE: This study examined the association between blood lead levels (PbB) and wild game consumption. METHODS: We recruited 742 participants, aged 2-92 years, from six North Dakota cities. Blood lead samples were collected from 736 persons. Information on socio-demographic background, housing, lead exposure source, and types of wild game consumption (i.e., venison, other game such as moose, birds) was also collected. Generalized estimating equations (GEE) were used to determine the association between PbB and wild game consumption. RESULTS: Most participants reported consuming wild game (80.8%) obtained from hunting (98.8%). The geometric mean PbB were 1.27 and 0.84 microg/dl among persons who did and did not consume wild game, respectively. After adjusting for potential confounders, persons who consumed wild game had 0.30 microg/dl (95% confidence interval: 0.16-0.44 microg/dl) higher PbB than persons who did not. For all game types, recent (<1 month) wild game consumption was associated with higher PbB. PbB was also higher among those who consumed a larger serving size (> or = 2 oz vs. <2 oz); however, this association was significant for 'other game' consumption only. CONCLUSIONS: Participants who consumed wild game had higher PbB than those who did not consume wild game. Careful review of butchering practices and monitoring of meat-packing processes may decrease lead exposure from wild game consumption.

PROBLEM: Between 1992 and 2005, 1412 workers on farms died from tractor overturns. A Rollover Protective Structure (ROPS) is a proven intervention to reduce overturn deaths. However, farm characteristics that are associated with the adoption of ROPS are not well understood. METHODS: ROPS prevalence statistics were derived from National Institute for Occupational Safety and Health (NIOSH) surveys that tracked ROPS use on farms. Data were from the years 1993, 2001, and 2004. RESULTS: In 1993, 38% of tractors were equipped with ROPS. This increased to 51% by 2004. ROPS prevalence rates were higher on farms in the Southern region of the United States, on farms where the operator was 25-34 years old, and on farms with $100,000 or more of farm sales. Low ROPS prevalence rates were associated with farm operators 65 years old or older and with farms with less than $10,000 of farm product sales. SUMMARY: The increase in ROPS prevalence between 1993 and 2004 has not been sufficient to decrease the rate of tractor overturn deaths on farms. Incentive programs targeting older farm operators and low-income farm operations are suggested to increase ROPS use on tractors. IMPACT ON INDUSTRY: The study provides farm characteristics associated with low ROPS prevalence rates. The results can be used to target farms for future ROPS promotion activities.

BACKGROUND: Numerous studies document the health benefits of a physically active lifestyle, but relatively few document the hazards of physical activity. Because of the requirement for physical fitness to complete their mission, the United States military services have a vested interest in understanding the benefits and risks of physical activity including exercise and sports. One of these risks is injury. Rates and proportion of injuries caused by exercise- and sports-related (ESR) activities have not been reported previously across the services. PURPOSE: The purposes of this population survey were to (1) document the rates and proportion of all injuries caused by ESR activities among military personnel, (2) compare rates across the military services, and (3) describe the causes and types of ESR injuries as well as associated days of limited activity. STUDY DESIGN: Descriptive epidemiology study. METHODS: The Defense Manpower Data Center administered the web-based 2008 Status of Forces Survey of Active Duty Service Members to a random sample of active-duty personnel. In all, 10,692 servicemembers completed the survey, which included questions about injuries from any cause and from exercise and sports during the previous year. Responses were weighted to produce population estimates for injury rates (any injury and ESR injury). Percentage distributions were used to describe activities, injury types, days of limited activity, and contributing factors for ESR injuries. RESULTS: There were 49% of servicemembers who sustained an injury from any cause in the previous year; 25% had an ESR injury. Thus, 52% of all injuries were ESR injuries. ESR injury rates ranged from 20% for the Navy to 33% for the Marine Corps. Running accounted for 45% of ESR injuries. Forty percent of ESR injuries were sprains and strains. As an indicator of injury severity, 35% of ESR injuries required more than 2 weeks of limited activity. CONCLUSION: This study quantified the overall incidence of injuries and the large proportion that are caused by exercise and sports among military personnel, a population of healthy, physically active adults. Prevention strategies should focus on running, weight training, basketball, and football. Recommendations include adherence to evidence-based practices to reduce the occurrence of ESR injuries.

The aim of this study was to document risk factors for any injury and sports- and exercise-related injuries, including personal and occupational stress among active duty service members (SMs) in the Air Force, Army, Marine Corps, and Navy. A total of 10,692 SMs completed the April 2008 Status of Forces Survey of Active Duty Members. The survey asked about demographics, personal stress and occupational stress, injuries from any cause, and participation in sports- and exercise- related activities in the past year. The survey used a complex sampling procedure to create a representative sample of SMs. Logistic regression was used to examine the associations of injury outcomes with potential risk factors. 49% of SMs sought medical care for an injury in the past year and 25% sustained a sports- and exercise-related activities injury. Odds of injury were higher for the Army and Marine Corps than for the Air Force or Navy. This survey showed that higher personal and occupational stress was associated with higher risks of injury. SMs who experienced higher levels of personal or occupational stress reported higher risks of injuries. The effects of stress reduction programs on injury risks should be evaluated in military and other young physically active populations.
