Smoke alarm and battery function 42 months after installation: a randomized trial. Am J Prev Med 2010; 39:368-71. [PMID: 20837289 DOI: 10.1016/j.amepre.2010.05.018] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/11/2010] [Revised: 03/22/2010] [Accepted: 05/29/2010] [Indexed: 10/19/2022]
Abstract
BACKGROUND This randomized trial presents findings from the longest follow-up study of smoke alarm and battery function to date. PURPOSE The purpose of this study is to examine differences in long-term function of smoke alarm and battery combinations. METHODS A total of 691 households in an ongoing cohort study were randomly allocated into smoke alarm groups of ionizing and photoelectric and battery groups of zinc and lithium. Smoke alarm function was measured in 633 (91.6%) households from January 2007 through February 2008, 42 months following original smoke alarm/battery installation. Data analyses were conducted in 2009. RESULTS After 3.5 years, 81.9% of the 1898 smoke alarms were functional. Ionizing alarms with zinc batteries were the least likely to function (72.7%). In comparison, photoelectric alarms with lithium batteries were 2.9 times (95% CI=1.8, 4.5) more likely to function; ionizing alarms with lithium batteries were 2.0 times (95% CI=1.3, 3.1) more likely to function; and photoelectric alarms with zinc batteries were 1.7 times (95% CI=1.1, 2.5) more likely to function. Functionality was strongly tied to number of reports of nuisance alarms, which was higher for ionizing than photoelectric alarms. CONCLUSIONS Photoelectric smoke alarms and lithium batteries are the most likely to function long after smoke alarm installation, and may be worthwhile investments despite their increased cost.

Abstract
The Keokuk County Rural Health Study (KCRHS) is a population-based, prospective study of health status and environmental exposures of a large stratified random sample of residents in one rural Iowa county. The study focuses on injury and respiratory disease and monitors health care delivery, geriatric health, mental health, and other health outcomes, as well as behavioral risk factors for disease and injury. Injury and disease prevalence is investigated in relation to occupational, agricultural, and other environmental exposures. The KCRHS enrolled 1004 families in Round 1 (1994 to 1998) and 1002 families in Round 2 (1999 to 2004). Participants range in age from newborn to 98 years of age and are about equally divided between males and females. The families live in farm, rural nonfarm, and town households, representing men, women, and children, the elderly, farmers, and nonfarmers. The KCRHS is currently in Round 3 (2006-2011). Although the sample is stratified by residence type, the entire county is, by definition, rural, because the largest town has fewer than 2500 residents. Using the Keokuk County Rural Health Study as an example, this paper describes the methodological challenges faced in conducting a large rural prospective population-based cohort study. Some of these challenges are inherent in any large cohort study; others are unique to rural cohort studies. Topics considered include planning the study, developing the protocol, sampling, recruiting and tracking subjects, data collection and management, sustaining funding, relating to the community, and sharing data.

Abstract
BACKGROUND Previous studies indicate 20% of injuries represent 80% of injury costs in agriculture. To help prevent the most costly injuries, we aimed to identify characteristics and risk factors associated with serious injuries. METHODS We analyzed insurance records of 93,550 self-employed Finnish farmers. We ranked injury causes by claim cost and used multiple logistic regressions to identify risk factors for (any) injury and serious injury (injuries exceeding claim costs of 2000 euros). RESULTS A total of 5,507 compensated injuries occurred in 2002 (rate 5.9/100 person-years), and 1,167 or 21% of them (rate 1.25/100 person-years) were serious. The causes/sources resulting in highest average claim costs were motor vehicles; stairs, scaffoldings, and ladders; trailers and wagons; floors, walkways, and steps; other structures and obstacles; augers, mills, and grain handling equipment; horses; combines and harvesting equipment; tractor steps; and uneven and slippery terrain. Older age, male gender, higher income level, greater field size, residing on the farm, Finnish language (vs. Swedish), occupational health service (OHS) membership, and animal production were risk factors for injury. The risk factors for serious injury were similar; however, the effects of age, income level, and the raising of horses were more prominent. Language, residence, ownership status, and OHS membership were not risk factors for serious injury. CONCLUSIONS Cost-effective prevention efforts should address the following risk factors: older age, male gender, larger income and operation size, livestock production (particularly dairy, swine, and horses), motor vehicle incidents, falls from elevation, and slips, trips and falls.

Abstract
This was a 3-year retrospective cohort study of traumatic injuries in a midwestern pork meatpacking plant. Based on n = 5410 workers, this was a diverse workforce: Caucasian (56.6%), Hispanic (38.9%), African American (2.7%), Asian (1.1%) and Native American (0.8%). There were n = 1655 employees with traumatic injuries during this period. At 6 months of employment, the probability of injury was 33% in the harvest workers who were responsible for slaughter operations. The overall incidence injury rate was 22.76 per 100 full-time employees per year. Women experienced a higher incidence for injury than men. The risk ratio (RR) for traumatic injury was significantly lower in Hispanic workers compared to Caucasians (RR = 0.54, 95% CI = 0.49-0.60) and nonsignificantly higher in African American and Native American workers after adjusting for age, gender, work section assignment, and experience (RR = 1.33, 95% CI = 1.21-1.47). These findings suggest that either Hispanics are very safe employees or they underreport injuries. We make the case for the latter in the discussion.

Smoke alarms by type and battery life in rural households: a randomized controlled trial. Am J Prev Med 2008; 35:20-4. [PMID: 18482822 DOI: 10.1016/j.amepre.2008.03.020] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/31/2007] [Revised: 12/12/2007] [Accepted: 03/11/2008] [Indexed: 11/19/2022]
Abstract
BACKGROUND Although the use of smoke alarms is widely recommended, little guidance is available on the types of alarms and batteries that function best. This study examined smoke alarm and battery function 12 months after installation in rural residential households. METHODS An RCT, involving the installation of either a photoelectric or ionizing smoke alarm with either a lithium or carbon-zinc battery, was conducted in 643 rural Iowa households in July 2003. The functionality of each installed smoke alarm was tested 12 months later. Generalized estimating equations were used to model the effects of alarm type and battery type on alarm function and false alarms 12 months after installation. RESULTS Of 643 study homes, 98.8% had at least one functioning alarm, and 81.5% had all alarms functioning 12 months after installation. No difference was observed in alarm function between photoelectric alarms and ionizing alarms 12 months after installation (OR=1.30, 95% CI=0.88, 1.92). However, photoelectric alarms had significantly lower odds of false alarms than ionizing alarms. Alarms with lithium batteries had 91% higher odds of functioning than those with carbon-zinc batteries. The main reasons for nonfunctioning included a missing battery (30.7%); a missing alarm (28%); and a disconnected battery (11.3%). CONCLUSIONS Although lithium batteries and photoelectric alarms are more expensive than their counterparts, the financial investment might be worthwhile in terms of overall performance.

Abstract
CONTEXT Crash fatality and injury rates are higher on rural roadways than other roadway types. Although slow-moving farm vehicles and equipment are risk factors on rural roads, little is known about the characteristics of crashes with farm vehicles/equipment. PURPOSE To describe crashes and injuries for the drivers of farm vehicles/equipment and non-farm vehicles involved in an injury crash. Passengers are not included in this analysis. METHODS Injury crashes were included that involved a farm vehicle/equipment and at least one non-farm vehicle reported in Iowa Department of Transportation crash data from 1995 to 2004. Odds ratios were calculated through logistic regression to identify increased odds for injury among drivers of non-farm vehicles and farm vehicles/equipment. We examined frequently occurring crash characteristics to identify crash scenarios leading to the highest odds for injury. FINDINGS Non-farm vehicle drivers were 5.23 times more likely to be injured than farm vehicle/equipment drivers (95% CI = 4.12-6.46). The absence of restraint use was a significant predictor of injury for both farm vehicle/equipment drivers (OR = 2.85; 95% CI = 1.14-7.13) and non-farm vehicle drivers (OR = 2.53; 95% CI = 1.54-4.15). Crash characteristics increasing the odds of injury for non-farm vehicle drivers included speeding, passing the farm vehicle/equipment, driving on a county road, having a frontal impact collision, and crashing in darkness. Ejection was the strongest predictor of injury for the farm vehicle/equipment driver. CONCLUSION Non-farm vehicle drivers were much more likely to be injured than farm vehicle/equipment drivers, suggesting that farm vehicle/equipment crash prevention should be a priority for all rural road users. Prevention strategies that reduce motor vehicle speed, assist in safe passing, increase seat belt use, and increase conspicuousness of the farm vehicle/equipment are suggested.

Abstract
CONTEXT AND PURPOSE Rural households report high fire-related mortality and injury rates, but few studies have examined the risk factors for fires. This study aims to identify occupant and household characteristics that are associated with residential fires in a rural cohort. METHODS Of 1,005 households contacted in a single rural county, 691 (68.8%) agreed to participate. One household with missing information on a reported fire was excluded from the analysis. We used logistic regression to examine the independent association of occupant and household characteristics with reported fires, controlling for years lived in the residence. We also examined the association between the occurrence of previous fires and the adoption of safety measures. FINDINGS A total of 78 (11.3%) households reported a residential fire. Occupant characteristics that were associated with significantly higher odds of reported fires included the presence of an occupant with alcohol problems (OR = 1.82, 95% CI = 1.01-3.28) and being married (OR = 2.11, 95% CI = 1.14-3.91). Rural farm households were associated with significantly higher odds (OR = 1.72, 95% CI = 1.01-2.93) of reporting a fire when compared to residences in towns, after controlling for all other occupant and household characteristics. The presence of a fire extinguisher (OR = 2.00, 95% CI = 1.10-3.64) was the only fire safety measure that had a statistically significant association with reported fire. CONCLUSIONS Rural farm households report higher incidences of fire when compared to households located in towns. Experiencing a fire is not associated with an increased likelihood of adopting safety measures to prevent injuries once a fire has started.

Abstract
OBJECTIVE Although death rates from injuries are higher in rural areas compared with large metropolitan areas, little is known about how non-fatal injury rates vary by rurality. Data from the 1997-2001 US National Health Interview Surveys were used to explore associations between rurality and non-fatal injury. DESIGN A nationally representative survey. METHODS The annual injury rates per 1000 adults and 95% CIs were computed for medically attended injuries. Counties of residence were coded according to urban influence codes into four categories: large urban, small urban, suburban and rural. A linear-by-linear trend test was used to determine whether injury rates increase monotonically with county rurality. Logistic regression was used to control potential confounders. RESULTS Compared with large urban counties, small urban counties experienced 8% higher injury odds (95% CI 1% to 15%); suburban counties 20% higher injury odds (95% CI 10% to 31%); and rural counties 30% higher injury odds (95% CI 17% to 43%) after adjusting for age, gender, marital status, education and health insurance. CONCLUSIONS Rural residents had higher non-fatal injury rates than urban and suburban residents. Exploring this discrepancy can further contribute to new hypotheses regarding rural injury risk and ultimately lead to better suited interventions for rural residents.

Abstract
OBJECTIVE The authors used data from a population based prospective cohort study to determine if depressive symptoms predicted incidence of unintentional injury. METHODS The Keokuk County Rural Health Study, based in Iowa, is a prospective cohort study of health status that includes injury outcomes. Depressive symptoms were measured using the 11-item Center for Epidemiologic Studies Depression Scale at the beginning of the study on 1493 participants. Quarterly follow up phone calls were made to measure injury incidence. RESULTS 471 injuries were reported for an overall injury rate of 9.8 per 100 person-years. Crude injury rates were significantly higher for those with depressive symptoms (p = 0.0003). Those with depressive symptoms had a 41% increased risk for injury after controlling for antidepressant medication use, gender, prior injury, income, and sleepiness (RR = 1.41, 95% CI 1.10 to 1.80). Depressive symptoms remained a risk factor for injury regardless of current antidepressant medication use (no medication use, RR = 1.43, 95% CI 1.09 to 1.88; medication use, RR = 1.31, 95% CI 0.76 to 2.26). CONCLUSIONS Depressive symptoms were found to be risk factors for unintentional injury. Medical practitioners should consider talking about safety with their patients, especially those reporting symptoms of depression, and recognize that an increased risk for injury remains until the depressive symptoms subside.

Abstract
The aim of this study was to assess risk factors for low back injury requiring medical advice or treatment among Iowa farmers. Although farmers are at risk for low back injury, few studies have addressed risk factors for farm work-related low back injury. We screened 6999 participants in the Iowa portion of the Agricultural Health Study to identify 49 male farmers who reported farm work-related low back injury requiring medical advice or treatment in the previous year. We compared them with 465 uninjured male farmer controls. Multivariable modeling identified four risk factors significantly associated with low back injury: age less than 45 years (OR = 3.32; 95% CI 1.75-6.20), doctor-diagnosed asthma (OR = 4.26; 95% CI 1.49-12.10), education beyond high school (OR = 2.12; 95% CI 1.13-3.90), and difficulty hearing normal conversation (even with a hearing aid, in the case of those using one) (OR = 1.98; 95% CI 1.02-3.80). Although hearing difficulty may be a general risk factor for occupational injury, asthma may be a more specific risk factor for low back injury. Future research to assess the risk factors, asthma and difficulty hearing, may be particularly important, since farmers are at increased risk for hearing loss, and farmers come into contact with many inhaled agents that can cause asthma.

Abstract
OBJECTIVE The National Fire Protection Association (NFPA) has specific recommendations about the number, location, and type of smoke alarms that are needed to provide maximum protection for a household. No previous studies have examined whether or not homes are completely protected according to these guidelines. The authors describe the prevalence and home characteristics associated with compliance to recommendations for smoke alarm installation by the NFPA. DESIGN, SETTING, AND SUBJECTS Data are from the baseline on-site survey of a randomized trial to measure smoke alarm effectiveness. The trial was housed in a longitudinal cohort study in a rural Iowa county. Of 1005 homes invited, 691 (68.8%) participated. MAIN OUTCOME MEASURES Information about smoke alarm type, placement, and function, as well as home and occupant characteristics, was collected through an on-site household survey. RESULTS Although 86.0% of homes had at least one smoke alarm, only 22.3% of homes (approximately one in five) were adequately protected according to NFPA guidelines. Fourteen percent of homes had no functioning smoke alarms. More than half of the homes with smoke alarms did not have enough of them or had installed them incorrectly, and 42.4% of homes with alarms had at least one alarm that did not operate. Homes with at least one high school graduate were nearly four times more likely to be fully protected. Homes that had multiple levels, a basement, or were cluttered or poorly cleaned were significantly less likely to be fully protected. CONCLUSION These findings indicate that consumers may not be knowledgeable about the number of alarms they need or how to properly install them. Occupants are also not adequately maintaining the alarms that are installed.

Abstract
This study aimed to assess the association of sleep disturbance and injuries in a rural population of Iowa. Study participants were 1345 adults who were enrolled in the KCRHS. Sleep problems were assessed based on self-reports at the beginning of the study. Injury information was collected by telephone interviews an average of every 6 months from August 1999 to June 2004. Sleeping for less than 7.5 hours increased the risk for injuries by 61% (rate ratio, 1.61; 95% confidence interval, 1.21-2.15) compared with sleeping for 7.5 to 8.5 hours (reference). Snoring frequency/severity and daytime fatigue/sleepiness were not significant in predicting the risk for injuries. Alcohol consumption of 1 to 2 or more drinks per day increased the risk for injuries among those who had sleep problems. Having adequate hours of sleep is important in preventing injuries. Avoiding alcohol consumption would be especially helpful in reducing injuries among people with sleep disturbance.

Abstract
Agriculture remains one of the most hazardous industries in the U.S., with tractor overturns producing the greatest number of agricultural machinery-related fatalities. Rollover protective structures (ROPS) and seatbelts effectively reduce tractor overturn deaths. However, a large proportion of tractors in use in American agriculture are older tractors without ROPS and seatbelts. This article describes the tractor-related responses from participants in a population-based study conducted in Keokuk County, Iowa. This study was designed to measure rural and agricultural adverse health and injury outcomes and their respective risk factors. Questionnaires were partially developed from well-documented national surveys. Questions about agricultural machinery use, presence of safety equipment on the machinery, work practices, and attitudes about farm safety were included. Study participants on farms who owned tractors had an average of 3.1 tractors with an average age of 27 years. Only 39% of the 665 tractors had ROPS. Tractor age was associated with the presence of ROPS; 84% of tractors manufactured after 1984 were ROPS-equipped, whereas only 3% of tractors manufactured before 1960 were ROPS-equipped. ROPS-equipped tractors were significantly more common on larger farms and households with higher income. Only 4% of the farmers reported that their tractors had seatbelts and they wore them when operating their tractors. The results of this study support the findings of other studies, which indicate that many older tractors without ROPS and seatbelts remain in use in American agriculture. Until a dramatic reduction in the number of tractors in the U.S. operated without ROPS and seatbelts is achieved, the annual incidence of 120 to 130 deaths associated with tractor overturns will persist.

Abstract
BACKGROUND Homes in rural areas have a higher fire death rate. Although successful exit from a home fire could greatly reduce fire-related deaths and injuries, little is known about factors associated with behaviors of developing and practicing an escape plan. METHODS Between July 2003 and June 2004, a baseline survey was administered, in person, to 691 rural households. Information collected included a history of previous home fire, perceived risk of home fire, existing smoke alarms and their working status, and home fire safety practices, as well as home and occupant characteristics. The association of residents' perceived risk of home fire and fire escape plans was assessed. RESULTS Forty-two percent of rural households reported having a fire escape plan. Of the households with a plan, less than two thirds (56.9%) discussed or practiced the plan. Households with children were more likely to develop and practice a fire escape plan. Households with an elderly or disabled person were less likely to develop or practice the plan. Compared to respondents who perceived low or very low risk of home fire, those who perceived a high or very high risk had 3.5 times greater odds of having a fire escape plan and 5.5 times greater odds of discussion or practicing their plan. CONCLUSIONS Increasing awareness of the potential risk of home fires may help occupants develop and practice home fire escape plans. In order to reduce fire deaths and injuries, different strategies need to be developed for those households in which the occupants lack the ability to escape.

Abstract
BACKGROUND Therapeutic trauma laparotomy (TTL) is a common emergency procedure after traumatic abdominal injury, but it can lead to complications and even death. We explored the role of the time from emergency department (ED) arrival to surgical intervention as a predictor of complications and mortality from TTL. STUDY DESIGN This is a retrospective study of 175 patients receiving TTL between July 1997 and October 2003 in a Level I teaching hospital serving a primarily rural population. Mortality after TTL and complications, both general and abdominal, were the main outcomes. Time from ED arrival to operation was the primary exposure. Confounders, including time from injury to ED arrival, age, gender, injury severity, and patient status, were controlled in logistic models. RESULTS Of the 175 TTL patients, 23 (13.1%) died, 102 (58.3%) had abdominal complications, and 119 (68.0%) had general complications. Controlling for confounders, patients whose operation began more than 1 hour after ED arrival were 11.3 (95% CI=2.2 to 58.8) times more likely to die and 3.1 (95% CI=1.44 to 6.60) times more likely to have complications. CONCLUSIONS The traumatologist has little control over patient treatment and transfer before ED arrival. After arrival the traumatologist can reduce negative outcomes by reducing the time for patient assessment and start of TTL, when warranted.

Abstract
Although agriculture is one of the most hazardous industries, the costs of agricultural injuries and illnesses are not well known. This study aimed to determine the cost burden from compensated injuries and occupational diseases in Finnish agriculture using workers compensation records. The incidence rates in 1996 were 7.4/100 for injuries and 0.61/100 for occupational diseases. Men had a higher risk of injury (RR = 1.89; 95% CI: 1.81-1.97), but a lower risk of an occupational disease (RR = 0.68; 95% CI: 0.60-0.78), compared to women. The total cost burden was 75 (Euros) per person in 1983, increasing to 215 in 1999. The total insurance cost in 1996 was 23.5 million consisting of medical care (16%), per diem (lost time compensation within one year from the incident) (37%), pension (lost time compensation after one year from the incident) (23%), survivors pension (3%), impairment allowance (7%), rehabilitation (6%), and other costs (9%). The total cost was 0.7% of the national gross farm income and 2.2% of the net farm income. The mean cost of 1996 cases was 1340 for injuries and 6636 for occupational diseases. Injuries represented 92% of the claims and 71% of the total costs. Occupational diseases represented 8% of the claims and 29% of the costs. Twenty percent of the most severe claims represented 79.5% of the total insurance costs. Injuries and occupational diseases result in significant costs in agriculture. Lost time was the largest cost item. Overall, injuries were more costly than occupational diseases. This study indicates that the 20%-80% rule applies to agricultural injury and illness costs, and from the cost standpoint, it is important to focus prevention efforts on the most severe incidents.

Abstract
BACKGROUND Self-reported hearing measures are useful for surveying hearing loss in a population because they are short, and easy to administer by either questionnaire or telephone. This study aims to assess the performance of several self-reported hearing measures to identify hearing loss in a group of Iowa farmers. METHODS The study subjects were 98 male farmers who participated in the Iowa Farm Family Health and Hazard Survey. We tested three self-reported hearing measures; the hearing screening questions, the Rating Scale for Each Ear (RSEE), and the Health, Education and Welfare-Expanded Hearing Ability Scale (HEW-EHAS), which were originally developed and implemented in the National Health Interview Survey. The sensitivity and specificity of the self-reported hearing measures were assessed by comparing them with pure tone threshold averages. These sensitivity and specificity measures were compared between younger and older age groups. RESULTS The sensitivities of the screening questions, RSEE, and HEW-EHAS were 73.0%, 66.7%, and 53.3%, respectively. The specificities of the self-reported hearing measures were similar, which ranged from 81.4% to 84.8%. The sensitivities of the self-reported hearing measures were higher in the younger age group while the specificities were higher in the older age group. CONCLUSIONS The results of this study support the use of simple screening questions in identifying hearing loss among farmers.

Abstract
BACKGROUND Previous studies suggested that hearing impairment based on self-report might increase the risk of agricultural injuries. However, self-reported hearing measures may be subject to inaccuracy and subjective perception. We assessed the association of agricultural injuries with hearing loss and other hearing characteristics using measured hearing. METHODS Study subjects were 150 farmers who participated in the Iowa Certified Safe Farm study. Injury information was collected by telephone interviews at 2-5 month intervals from September 1999 to October 2002. Hearing levels were measured annually using the pure tone audiometry from 1998 to 2002. Adjusted rate ratios of injuries were calculated using the multivariate Poisson regression model. RESULTS Hearing loss in the better ear (RR = 1.62), hearing asymmetry (RR = 1.67), and fair/poor self-reported hearing (RR = 1.96) were significantly associated with the risk of agricultural injuries. It is notable that self-reported hearing might be a stronger predictor of injuries than pure tone audiometry (PTA). Exposure to noise elevated the risk of injuries in those farmers with hearing loss or hearing asymmetry. The occasional use of hearing protection was significantly associated with agricultural injuries. CONCLUSIONS This study adds substantial evidence that hearing loss acts as a risk for agricultural injuries. Prevention of hearing loss and noise exposure may be important in reducing the burden of agricultural injuries.

Abstract
OBJECTIVE This study estimates the prevalence of male abusive behavior reported by men and their female partners and identifies characteristics of abusive men. DESIGN Baseline survey from a population based cohort study of general health. SETTING A rural county in Iowa, USA. SUBJECTS 572 men and their cohabitating female partners. MAIN OUTCOME MEASURES Male-to-female physical, emotional, and sexual abuse reported by either partner. RESULTS In this cohort, 13.6% of men had performed at least one act of physical abuse and 34.9% emotional abuse. More than 45% of abusive men reported their own behaviors. Alcohol problems, antisocial personality characteristics, depressive symptoms, and financial stress were all positively associated with both physical and emotional abuse, but suicidal thoughts were less likely among abusers. CONCLUSION Identification of common characteristics of abusive men may predict proclivity towards partner violence and barriers to behavior modification.

Abstract
BACKGROUND The objective of this study was to measure changes in injury claim rates after a premium discount program was implemented in the Finnish farmers' workers' compensation insurance. We focused on measures that could indicate whether the changes occurred in the true underlying injury rate, or only in claims reporting. METHODS Monthly injury claim rates were constructed at seven disability duration levels from January 1990 to December 2003. We conducted interrupted time series analyses to measure changes in the injury claim rates after the premium discount was implemented on July 1, 1997. Three additional policy change indicators were included in the analyses. RESULTS The overall injury claim rate decreased 10.2%. Decreases occurred at four severity levels (measured by compensated disability days): 0 days (16.3%), 1-6 days (14.1%), 7-13 days (19.5%), and 14-29 days (8.4%). No changes were observed at higher severity levels. Minor injuries had a seasonal pattern with higher rates in summer months while severe injuries did not have a seasonal pattern. CONCLUSIONS The premium discount decreased the overall claim rate. Decreases were observed in all categories up to 29 disability days. This pattern suggests that under-reporting contributes to the decrease but may not be the only factor. The value of the premium discount is lower than the value of a lost-time claim, so there was no financial reason to under-report lost-time injuries. Under-reporting would be expected to be greatest in the 0 day category, but that was not the case. These observations suggest that in addition to under-reporting, the premium discount may also have some preventive effect.

Abstract
OBJECTIVE The current paper estimates the prevalence of hearing problems in a rural population, analyzes the prevalence of hearing problems across age groups, and compares the prevalence of hearing problems in this population with results obtained in other populations. DESIGN Data were obtained from a random sample of the residents of a rural county, stratified by farm, rural non-farm, and town residence. Hearing test results were obtained from participants between the ages of 8 and 92 years (N = 1972; 47% male). Pure-tone thresholds were classified as normal or impaired using a number of metrics, including speech intelligibility index values. Selected comparisons of crude rates were made with previous population-based studies of hearing loss prevalence. RESULTS Nearly all (99%) of the participants in this study had significant hearing impairment. Atypical hearing impairment is most prevalent at 6 kHz. In males, this excess impairment shifts to lower frequencies with age but monotonically decreases in females. Notched configurations were most common among those between 30 and 59 years old. In females, the prevalence of hearing impairments sufficient to interfere with speech understanding begins to rapidly increase in the 6th decade (4th decade in males). Comparisons with prior population-based studies in the United States and Great Britain identified few significant differences. CONCLUSIONS Significant hearing impairment is common in rural populations. The high prevalence in this population is similar to that found in other population-based studies. Future studies are needed to examine (1) the risk factors for hearing impairment, (2) the natural course of hearing problems across the life span, and (3) the effect of programs for the prevention of hearing impairment and rehabilitation for persons with existing hearing impairments.

Abstract
OBJECTIVES Motor vehicle crash fatality rates have been consistently higher in rural areas than in urban areas. However, the explanations for these differences are less clear. In this study the decomposition method was used to explore the factors associated with increased fatal crash involvement rates in rural communities. DESIGN Using national databases, the fatal crash incidence density was decomposed into the product of three factors: the injury fatality rate, the crash injury rate, and the crash incidence density. RESULTS As expected, the fatal crash incidence density was more than two times higher in rural than in urban areas. This was driven primarily by the injury fatality rate, which was almost three times higher in rural areas. CONCLUSIONS Further research should examine the relative roles of crash severity and the timely receipt of definitive medical care after a crash.

Abstract
In the United States, injuries are the leading cause of death among individuals aged 1 to 45 years and the fourth leading cause of death overall. Rural populations exhibit disproportionately high injury mortality rates. Deaths resulting from motor vehicle crashes, traumatic occupational injuries, drowning, residential fires, and suicide all increase with increasing rurality. We describe differences in rates and patterns of injury among rural and urban populations and discuss factors that contribute to these differences.

Abstract
BACKGROUND Farmers are at increased risk for fall-related injury compared with other occupations. Little is known about risk factors for non-fatal falls on the farm. This case-control study, nested within the Agricultural Health Study, aimed to assess risk factors for work-related falls among Iowa farmers. METHODS A screener questionnaire sent to 6,999 farmers in 1998 identified 79 farmers who reported a fall-related farm injury that required medical advice or treatment in the previous year. Multivariable logistic regression analysis was used to assess several possible risk factors for injury among these farmers compared with 473 farmers with no injury in the previous year. RESULTS There were significant associations between fall-related farm injury and age between 40 and 64 years (OR = 2.21; 95% CI = 1.20-4.07), doctor-diagnosed arthritis/rheumatism (OR = 2.05; 95% CI = 1.11-3.79), difficulty hearing normal conversation (even with a hearing aid, in the case of those who used one) (OR = 1.82; 95% CI = 1.07-3.08), and taking medications regularly (OR = 1.80; 95% CI = 1.02-3.18). CONCLUSIONS Aging and health impairments, such as arthritis and hearing difficulties, are risk factors for which accommodations and preventive strategies can be devised to prevent fall-related injuries on the farm.

Abstract
OBJECTIVE To identify risk factors for non-fatal injury among rural children. DESIGN Cross sectional health interview survey, 1994-98. SETTING A rural Iowa county, not adjacent to a metropolitan area. SUBJECTS Stratified, random sample of households, including all resident children and adults. MAIN OUTCOME MEASURES Injury episodes in the past 12 months among children aged 0-17 years and the parental and child characteristics associated with these episodes. RESULTS Of the 621 children in participating households, 137 or 22.1% were injured during the past 12 months. Children age 5-17 on a sports team were 1.88 times (95% confidence interval (CI) 1.07 to 3.31) more likely than other children to be injured. Children age 12-17 who binge drink were 3.50 times (95% CI 1.31 to 9.50) more likely than other children to be injured. Compared with children not on sports teams, girls on teams were 2.26 times (95% CI 1.02 to 5.13) more likely while boys on teams were 1.60 times (95% CI 0.71 to 3.68) more likely to have an injury episode. Compared with children who did not binge drink, girls binge drinking were 8.11 times (95% CI 1.52 to 43.33) more likely while boys binge drinking were 2.19 times (95% CI 0.70 to 6.84) more likely to have an injury episode. CONCLUSIONS Local studies such as this can provide useful clues regarding the etiology of injury. Some known and some new potential risk factors including behavioral aspects for childhood non-fatal injury in a very rural area were investigated. It is planned to address these cross sectional findings in future longitudinal follow up of this population.

Abstract
Although nonfatal burn injuries vastly outnumber fatal injuries, their epidemiology is not well defined. We sought to determine the epidemiology of nonfatal burn injuries in a largely rural region of a midwestern state to target intervention efforts at populations and injury mechanisms at risk. Data were retrospectively collected on a population-based sample of medically treated burn injuries in 10 counties in southern Iowa from 1997 to 1999 using International Classification of Diseases, 9th Revision, Clinical Modification codes (ICD-9-CM, Ncode 940-949) to identify burn-related emergency room visits from computerized lists. A total of 1430 emergency room visits were identified, with 1382 records available for review. Injuries were grouped into etiology subcategories to better delineate common mechanisms and determine methods of prevention. Scald and hot-object contact and flame-related injuries were the leading causes of burn injury. Scald and contact injuries were subdivided into three major sets of scenarios, scald and contact injuries related to household food preparation and consumption, work-related scald and contact injuries. and injuries resulting from contact with nonfood and nonbeverage-related household objects. Children ages 0 to 4 had the highest population-based scald and hot-object contact injury rate of all age groups, with an average annual incidence rate of 35.9 per 10,000. Injuries in this age group were most commonly related to household objects (34.7%) followed by food preparation (25.3%). Children and young adults ages 5 to 24 were also the most likely to be injured by flame and fire-related causes secondary to open fires. Nonfatal burn injuries typically afflict children and young adults in definable patterns, suggesting intervention strategies. Future studies need to better delineate the contributing factors associated with these injuries to refine the intervention strategies.

Abstract
Injury and illness among youth working on farms are important problems. The types of farm tasks performed by children and the ages at which they begin these activities have not been well characterized. This cross-sectional study characterized agricultural work performed by adolescents in a rural Iowa county to better understand the patterns and extent of exposures to agricultural risk factors. This information will help to develop prevention strategies for agriculture-related injury and illnesses for children working on farms. The Keokuk County Rural Health Study is a prospective cohort study of randomly selected households in Iowa. In Round 2, all youth, aged 12 to 17 years participating in this population-based study, were asked about their use of farm machinery, work with livestock, pesticide handling, and other farm activities. The age at which they actually began these activities, the age they believed youth should start these activities, and sources of health and safety training they received were also ascertained. Adults in the study were asked the same questions about youth. Matched parental reports and opinions were compared to their children's reports and opinions using McNemar's chi-square tests. A total of 143 youth and 684 adults with farming experience completed the interviews. There were 118 pairs of parents and youth. Fifty percent of male youth, and 18 percent of females had performed agricultural work at some time in their life. Twenty-five percent of all male youth, and 5 percent of females were currently working on farms. Close to 30 percent had driven tractors, all-terrain vehicles, and pick-up trucks. Despite the legal prohibition of hazardous work by children under age 16, several younger children reported that they had driven a self-propelled combine, worked in silos, or handled and applied fertilizers in the past 12 months. Youth began riding on tractors at a mean age of 7. The mean ages for driving tractors and all-terrain vehicles were 11 and 10, respectively. The mean age for driving a self-propelled combine was 13. Children began applying or handling fertilizers at the age of 12. There were discrepancies between parent and youth reports regarding the frequencies, starting age, and opinions relative to performing agricultural tasks. These results suggest the need for implementing guidelines, particularly for age appropriate agricultural tasks.

Abstract
CONTEXT Although farmers are at risk for injuries from contact with large livestock, few previous studies have examined risk factors for animal-related injuries. PURPOSE This case-control study, nested in the Agricultural Health Study, aimed to assess risk factors for animal-related injury among Iowa large-livestock farmers. METHODS A screener questionnaire sent to 6999 farmers identified 116 farmers with large livestock who had an animal-related injury requiring medical advice/treatment in the previous year. Several possible risk factors for injury were assessed by comparing these farmers with 342 farmers who had livestock but were not injured in the previous year. FINDINGS A multiple logistic regression analysis showed significant associations between animal-related injury and the use of a hearing aid (odds ratio [OR] = 5.4 [95% CI, 1.6 to 18.0]), doctor-diagnosed arthritis or rheumatism (OR = 3.0 [95% CI, 1.7 to 5.2]), education beyond high school (OR = 1.8 [95% CI, 1.1 to 2.8]), and a younger age. Farmers engaged in off-farm work were less likely to sustain animal-related injuries (OR = 0.4 [95% CI, 0.2 to 0.8]). CONCLUSIONS This is the first study to show associations between animal-related injury and a younger age, hearing difficulties, and doctor-diagnosed arthritis. Hearing loss and arthritis, which are more common among farmers than among other workers, may be particularly important risk factors to address in future preventive studies.

Abstract
As American workers age, workers with impairments and functional limitations make up a larger percentage of our workforce. This investigation presents data from the National Health Interview Survey Disability Supplement 1994-1995 (NHIS-D) describing the nature of workplace accommodations in the American workforce and factors associated with the provision of such accommodations. Of a nationally representative sample of workers aged 18 to 69 years with a wide range of impairments, 12% reported receiving workplace accommodations. Males (odds ratio (OR) 0.64: 95% confidence interval (CI) 0.53-0.78) and Southerners (OR 0.57; 95% CI = 0.47-0.70) were less likely than others to receive workplace accommodations. Those with mental health conditions were less likely than others to receive accommodations (OR 0.56; 95% CI = 0.44-0.70). College graduates (OR 1.53; 95% CI = 1.22-1.91), older workers, full time workers (OR 3.99; 95% CI = 2.63-3.87), and the self-employed (OR 1.76; 95% CI = 1.28-2.41) were more likely than others to receive accommodations.

Abstract
This study identifies factors associated with mode of transport to rural hospitals. We evaluated 11,541 trauma patient visits that came by ground ambulance or private vehicle to the Emergency Department of one of six northwest Iowa rural hospitals. We performed univariate analyses and logistic regression analyses to identify factors associated with mode of transport for each severity level (fatal, major and minor). For major/fatal injuries, we found that those aged 65 years and over were 3.6 (95% CI = 2.7-4.9) times more likely to use ambulances than those under 15. Motor vehicle traffic injuries and hip fractures were also associated with ambulance usage, while arm fractures and farm-related injuries were not. We conclude that for major/fatal injuries, older persons, those injured from high velocity causes, and those with hip fractures are more likely to use an ambulance. Emergency Medical Services may improve the community's ambulance utilization by providing public education (e.g., proper use of 911 and injury severity recognition), and by collaborating with dispatch, the local community and health care providers. Further study of the community's and individuals' decision-making factors determining mode of transportation is needed.

Abstract
The purpose of this case-control study nested in the Agricultural Health Study was to assess risk factors for agricultural injury among a large group of Iowa farmers. A questionnaire sent to 6,999 farmers identified 431 cases who had a farm work-related injury requiring medical advice/treatment in the previous year and 473 controls who had no injury in the previous year. We assessed several potential risk factors for injury. A multiple logistic regression analysis showed significant associations between farm work-related injury and weekly farming work hours (> or = 50 hours/week) (OR = 1.65; 95% CI = 1.23-2.21), the presence of large livestock (OR = 1.77; 95% CI = 1.24-2.51), education beyond high school (OR = 1.61; 95% CI = 1.21-2.12), regular medication use (OR = 1.44; 95% CI = 1.04-1.96), wearing a hearing aid (OR = 2.36; 95% CI = 1.07-5.20), and younger age. These results confirm the importance of risk factors identified in previous analytic studies and suggest directions for future research in preventive intervention strategies to reduce farm work-related injuries.

Abstract
The Keokuk County Rural Health Study (KCRHS) was designed as a 20-year, prospective cohort study focusing on chronic disease and injury in an agricultural southeastern Iowa county. The goals of the KCRHS are to prospectively describe, measure, and analyze prevalent rural and agriculturally related adverse health outcomes and their respective risk factors and to provide the basis for future community-based intervention programs to reduce disease and injury incidence. Methods of data collection included in-person interviews, medical screenings, and environmental assessments of homes and farms. All households studied were rural; comparisons were made among farm, rural nonfarm, and town households, between men and women, and between smokers and nonsmokers. The present paper reports selected adult baseline data from Round 1 of this study. Residents of farm households were somewhat younger and better educated than residents of rural nonfarm and town households; smoked less; were more likely to have ridden an all-terrain vehicle; and were more likely to report firearms in the home. Eighty-nine percent of the men and 66% of the women engaged in farming or did so in the past. Men more often reported hearing loss, were more often overweight and obese, more often reported an injury, less often reported asthma, and less often saw a medical practitioner. Women reported poorer emotional health and higher rates of depression symptoms. The KCRHS has identified several modifiable health outcomes and risk factors as candidates for further analysis and targets for community-based prevention and intervention programs.

Abstract
OBJECTIVE To examine the prevalence and correlates of suicidal ideation in a community-based rural sample. METHOD The sample was a random sample of people living in a single county in Iowa. Participants aged 18 or older (n=1617) were asked about suicidal ideation in the past year as well as mood, alcohol use, social support, and stressful life events. RESULTS About 8.2% of the sample reported suicidal ideation. Depressive symptoms, problems resulting from alcohol use, infrequent social contact and financial loss characterized the suicidal group. CONCLUSION Depressive symptoms were the strongest correlate of suicidal ideation in this rural sample. In the multivariate analysis, financial loss rather than low income remained a significant correlate of suicidal ideation after controlling for depression. This suggests that change in financial status rather than chronic poverty poses a risk for suicidal ideation.

Abstract
Farm machinery is a major cause of injury morbidity and mortality among farmers. This case-control study assessed risk factors for machinery-related injuries among Iowa farmers. A screener questionnaire sent to 6,999 farmers in 1998 identified 205 farmers who had machinery-related injuries requiring medical advice/treatment in the previous year. Possible risk factors for injury were assessed among these farmers compared with 473 farmers with no injury in the previous year. A multiple logistic regression analysis showed significant associations between machinery-related injury and hours per week spent on farmwork (OR = 2.02; 95% CI 1.38-2.94), fewer years of farming experience (OR = 1.79; 95% CI 1.14-2.79), wearing a hearing aid (OR = 4.37; 95% CI 1.55-12.25), and a high CAGE score suggesting problem drinking (OR = 2.49; 95% CI 1.00-6.19). This is the first study to show associations between machinery-related injury and hearing impairment, problem drinking, and fewer years of farming experience. These findings may be useful for future interventions to decrease injuries related to farm machinery.

Abstract
This study compares the prevalence of the health risk factors for chronic disease and injury among farmers with their prevalence among other workers, using data from the Iowa Behavioral Risk Factor Surveillance System. From January 1999 to December 1999, there were 3,620 adults who participated in the survey. This report focuses on the 2,140 subjects who reported they were working. We calculated the percentage with each health risk factor, the adjusted odds ratio (OR) and the associated 95% confidence interval (CI), comparing the prevalence of health risks among farmers and other workers. Most health conditions and risk factors were similar among farmers and other workers. However, we found that farmers had some protective behaviors. They had better oral health (OR = 0.34, 95% CI 0.20-0.57) and were less likely to smoke (OR = 0.14, 95% CI 0.06-0.29) than other workers. In contrast, we found that farmers reported some high-risk behaviors compared to other workers. They were less likely to have smoke detectors at home (OR = 0.39, 95% CI 0.18-0.82), or to have had stool blood screening for colorectal cancer (OR = 0.41, 95% CI 0.1 7-1.00). These results suggest areas for future research to define targeted preventive interventions in farm communities.

Abstract
OBJECTIVE Undertriage has seldom been evaluated in the trauma population. In rural states patients often go to the nearest hospital first, where they are evaluated and, if necessary, transferred to another hospital. If they are undertriaged when transferred to the second hospital, they will require a second transfer to a higher-level trauma center. METHODS The authors retrospectively reviewed the charts of all trauma patients at a level I trauma center from 1996 to 1999 who were seen at two acute care facilities because of a single acute traumatic event before reaching the trauma center. Ninety-three patient charts were analyzed. RESULTS Forty-six percent of the patients were victims of a motor vehicle crash. Patients were mostly transferred to the level I trauma center for non-spine orthopedic injuries (28%), followed by spine injuries (14%) and head injuries (13%). These patients were stable, as manifested by an average trauma score of 11.6. However, there was a significant positive interaction between injury severity score and time to definitive care. CONCLUSIONS The authors infer from the data analysis that more serious or complex injuries took longer to evaluate. Since these patients were physiologically stable, reducing the number of twice-transferred trauma patients will involve refining transfer protocols concerning the need for specialty care.

Abstract
Using the National Health Interview Survey Disability Supplement of 1994 to 1995, we examined the factors associated with employment among Americans with disabilities. Persons with disabilities who were more educated were more likely to be working. Married men were more likely to work than unmarried men (odds ratio [OR], 1.58). Blacks were less likely to work than whites (OR, 0.56). Persons with disabilities related to cardiovascular disease (OR, 0.23), musculoskeletal disease (OR, 0.37), and respiratory disease (OR, 0.23) were less likely to work than other Americans with disabilities. Among persons with psychiatric disorders, there was considerable variety in the propensity to work. Persons with schizophrenia (OR, 0.24) and paranoid delusional disorder (OR, 0.34) were markedly less likely to work; persons with bipolar disorder (OR, 0.60) and major depression (OR, 0.69) were also less likely to work. Lastly, persons with self-reported alcohol abuse (OR, 1.30) were more likely to work, and persons with self-reported drug abuse (OR, 0.93) were not less likely to work, than others in our study population of Americans with disabilities.

Abstract
BACKGROUND Back pain causes considerable morbidity, disability, and economic loss among workers. Farmers handle heavy objects, often in awkward postures. However, the prevalence of back pain among farmers and the risk factors associated with back pain are not well known. METHODS In this study, we assess the frequency of risk factors for back pain among 287 Iowa male farmers. From 1992 to 1994, using a mail questionnaire, we collected data on potential risk factors for back pain. Eighteen months later, we surveyed occurrence of back pain as the outcome measure. RESULTS Thirty-one percent of farmers reported having daily back pain for a week or more during the past 12 months compared to 18.5% in the general working population. Using a multiple logistic regression model, we found two factors associated with back pain: 45-59 years of age (OR = 2.13, 95% CI 1.02-4.43) and having a non-agricultural job as the major occupation (OR = 2.02, 95% CI 0.98-4.17, P = 0.055). CONCLUSIONS Farmers had a significantly higher prevalence of back pain than the general working population. Middle-aged farmers and those with additional non-agricultural jobs had the highest risk for back pain.

Abstract
BACKGROUND Health behaviors represent major risks for premature morbidity and mortality. This study aimed to establish whether health risks varied substantially across occupational groups. METHODS We focused on the 2223 Iowa Behavioral Risk Factor Surveillance System (BRFSS) subjects who reported, in 1999, that they were currently working. RESULTS Even after controlling for age and gender, we found significant associations between occupation and health risk factors. We found these associations among the different categories of health risk factors, including insurance/access, health conditions, preventive behaviors, and screening behaviors. CONCLUSIONS The considerable differences in the prevalence of risk factors for chronic disease and injury across occupational groups in Iowa underscore the need for nationwide ongoing collection of occupational status in the BRFSS. These national data on the distribution of risk factors across occupations will support development of more targeted prevention interventions.

Abstract
BACKGROUND The purpose of this study was to describe the frequency, characteristics, and risk factors of unintentional adult injury in a rural population. METHODS We interviewed 1,644 adults representing an all-rural county in Iowa. Analyses used bivariate and multivariable logistic regression. RESULTS Participants' mean age was 53 years, and 54% were women. Twenty-three percent (n = 380) of participants reported an injury during the past 12 months, of which four fifths were treated. Overexertion (25%) and falls (22%) caused nearly half the injuries. Women with high levels of depression symptoms had 1.57 times (95% confidence interval, 1.05-2.33) the prevalence of injury occurrence as did women with low levels of depression symptoms. Men with a CAGE score of 2 or more had between 0.98 and 2.56 times (according to the range of values of the relevant odds ratio 95% confidence interval) the prevalence of injury episode of men without this exposure. CONCLUSION The association of injury occurrence with alcohol problems is consistent with prior research, but the increased prevalence of injury associated with high levels of symptoms of depression requires further study and explanation.

Abstract
BACKGROUND A nested case-control analysis of high pesticide exposure events (HPEEs) was conducted using the Iowa farmers enrolled in the Agricultural Health Study (AHS). METHODS In the 12 months of the study, 36 of the 5,970 farmer applicators randomly chosen from the AHS cohort (six per 1,000 farmer applicators per year) met our definition of an HPEE, by reporting "an incident with fertilizers, weed killers, or other pesticides that caused an unusually high personal exposure" resulting in physical symptoms or a visit to a health care provider or hospital. Eligibility criteria were met by 25 HPEE cases and 603 randomly selected controls. RESULTS Significant risk factors for an HPEE included: poor financial condition of the farm which limited the purchase of rollover protective structures OR = 4.6 (1.5-16.6), and having a high score on a risk acceptance scale OR = 3.8 (1.4-11.2). Other non-significant factors were also identified. CONCLUSIONS The limited statistical power of this study necessitates replication of these analyses with a larger sample. Nonetheless, the observed elevated odds ratios of an HPEE provide hypotheses for future studies that may lead to preventive action.

Abstract
Agriculture is one of the most hazardous occupations in the United States. We examined the work-related injury rate and risk factors among 290 Iowa male principal farm operators using a population-based, prospective study. Baseline data were collected between 1991 and 1994, and injury events were surveyed in the fall of 1995. Cumulative incidence of farmwork-related injury during the previous year was 10.5%. We found that depressive symptoms (odds ratio, 3.22; 95% confidence interval, 1.04 to 9.99) and the number of hours working with animals (odds ratio, 2.14; 95% confidence interval, 1.04 to 4.44) were associated with the incidence of farmwork-related injuries.

Abstract
OBJECTIVES In the United States, firearm deaths are almost as frequent as motor vehicle deaths. Firearm unintentional and suicide death rates are raised in rural areas. This study examines firearm prevalence and storage practices in three different types of rural households. METHODS Adults from a stratified random sample of 983 households in a rural Iowa county were interviewed. The chi2 test of independence was used to assess association between loaded, unlocked firearms and seven behavioral and demographic risk factors. RESULTS Nearly 67% of respondents reported firearms in their households. Nearly 7% of households had a loaded, unlocked gun. Prevalence of firearms at home was higher while prevalence of loaded, unlocked guns was lower than reported in other surveys. Prevalence of loaded, unlocked guns in farm households, 10.5%, was about twice the level in town households, 5.5% (chi2 test, p=0.033). Having taken a gun safety course was associated with more than double the prevalence of a loaded, unlocked gun, 13.5% v 5.1% (chi2 test, p=0.001). The prevalence of loaded, unlocked guns in households with a handgun, 19.3%, was four and one half times higher than in households with a long gun only, 4.2% (chi2 test, p=0.001). Households with someone with a lifetime prevalence of alcohol abuse or dependence were about twice as likely as other households, 13.0% v 6.6% (chi2 test, p=0.004), to report having loaded, unlocked firearms. CONCLUSIONS Anyone interested in promoting safe storage of firearms in rural homes should consider these observations.

Abstract
Agricultural workers are exposed to a variety of hazards that increase their risk for dermatitis. Nevertheless, the prevalence, patterns, and risk factors for dermatitis have not been well characterized among farmers in the United States. We assessed the prevalence and risk factors for dermatitis among 382 male farmers and 256 wives of farmers in Iowa using a cross-sectional study design. From 1992 to 1994, we collected data on potential risk factors and dermatitis. The results showed that 9.6% of male farmers and 14.4% of wives of farmers reported dermatitis during the previous 12-month period. In multivariable models, a history of allergy (odds ratio [OR], 8.2; 95% confidence interval [CI], 2.0 to 33.3) was strongly associated with dermatitis among male farmers. Among wives of farmers, some college education (OR, 3.4; 95% CI, 1.1 to 9.9) and exposure to petroleum products (OR, 3.1; 95% CI, 1.3 to 7.0) were associated with dermatitis. These results can be used to form preventive efforts in controlling farmwork-related exposures.

Abstract
BACKGROUND Unintentional injuries represent a major cause of morbidity and mortality in rural communities. This study aimed to determine the distribution of injury risk factors in a rural Iowa community and to identify the rural subgroups at highest risk for injury. METHODS We reported on 1583 participants, aged > or =25 years, from Round One of the Keokuk County Rural Health Study, a longitudinal panel study of a rural community. The self-reported data were collected during face-to-face interviews. RESULTS Our data suggested that several risk factors for injury are not uniformly distributed among rural populations. Male farmers were significantly less likely to wear their seatbelts than townspeople or rural nonfarmers. However, farm women were as likely to wear seatbelts as other women. Both male and female farmers were more likely to use all-terrain vehicles than townspeople or rural nonfarmers. In contrast, townspeople were more likely to ride bicycles than either farmers or rural nonfarmers. Townspeople were less likely to have firearms in their homes than either farmers or rural nonfarmers. Farmers were most likely to have fired a gun in the last year. Male farmers aged <65 years were less than half as likely as other men the same age to report a history of alcohol abuse. Binge drinking was equally frequent among farmers, rural nonfarmers, and townspeople. CONCLUSIONS These differences in risk behavior in a rural county suggest the possibility of targeting specific rural injury prevention interventions at those with the highest risk for dangerous behavior.

Abstract
BACKGROUND Violence against workers is garnering increased attention as awareness grows of the toll violent events have on workers and work environments. METHODS In this review, we summarize information about surveillance of violent events in the workplace and summarize evaluations of intervention programs to reduce such violence. We describe surveillance programs that nationally collect data, and we compare some data. We summarize two systematic studies of workplace violence-prevention programs: The first study examined evaluations of the Crime Prevention Through Environmental Design approach to prevention, and the second examined evaluations of behavioral and administrative interventions. RESULTS Reliable national data sets of worker homicides exist, but case identification and coding problems have yet to be solved. Although the number of workplace homicides has decreased since the mid-1990s, much less is known about the incidence of nonfatal events. The role that prevention programs have played in reducing workplace homicide remains largely unknown because so few evaluations have been conducted. CONCLUSIONS Information about effective methods to reduce violence against workers is needed. Research that evaluates existing prevention programs, especially efforts conducted in a collaborative manner, will be invaluable to shaping effective programs in the future.
