Evaluation of the Implementation of the NFFF Stress First Aid Intervention in Career Fire Departments: A Cluster Randomized Controlled Trial.

Firefighting is inherently dangerous, though recently concerns have shifted from traditional fireground injuries (burns and asphyxiation) to a focus on mental and behavioral health. Although firefighters are remarkably resilient, research suggests many suffer negative psychological consequences from repeated exposures to trauma. While the Stress First Aid (SFA) model has gained increased attention and adoption among fire departments as a model for behavioral health training, it has not been formally evaluated. This cluster randomized controlled trial used a crossover design comparing the immediate SFA group to delayed SFA control to test the impact of the SFA on firefighters' mental and behavioral health changes after 10-12 months (n = 400; Mage = 37.6, 4.8% women). A convenience sample of 79 firefighters (Mage = 41.4; 8.7% women) provided evaluations on one or more of the training modules. Participants reported satisfaction with all training components (Peer team training 97.6%, Online SFA 94.9%, Curbside Manner 88.4%, After Action Review 89.4%) and reported success in changing personnel's perception of their department's ability to respond to behavioral health issues (SFA M = 3.93, Control 3.50; t = 2.52, p = 0.042). Future work should focus on additional resources and training to augment existing efforts to help departments continue their efforts.

A Single, Multimodal Exercise Tolerance Test Can Assess Combat Readiness in Army-ROTC Cadets: A Brief Report.

The Army Combat Fitness Test (ACFT) is a multi-event assessment battery designed to determine the combat readiness of U.S. Army personnel. However, for Reserve Officers' Training Corps (ROTC) programs the logistical demands of collegiate life make repeated administration of the ACFT challenging. The present study sought to design and evaluate a single, multimodal exercise tolerance test (METT) capable of serving as a time-efficient proxy measure of combat readiness. METHODS: Using a formal instrument design process, we constructed the METT to mimic the demands of the ACFT and assessed its reliability, validity, and responsiveness. RESULTS: The METT demonstrates minimal measurement error (i.e., a 2% coefficient of variation), concurrent validity with the ACFT (R2 = 0.327, F = 10.67, p < 0.001), the ability to classify cadets who may be at-risk for failing the ACFT (X2 = 8.16, p = 0.017, sensitivity = 0.878, specificity = 0.667), and appropriate change following a training intervention (5.69 ± 8.9%). CONCLUSIONS: The METT has the potential to provide a means to monitor progress, identify areas for improvement, and guide informed decision-making regarding individualization of cadet combat training plans.

The health of women in the US fire service.

BACKGROUND: Despite statements from national fire service organizations, including the International Association of Fire Fighters (IAFF) and the International Association of Fire Chiefs (IAFC), promoting a diverse work force related to gender within the fire service, rates of women firefighters remain very low. Thus, research into why this extensive gender disparity continues is a high priority. Recent years have seen a number of large scale studies on firefighter health and health risk behaviors however, none have focused on the health of women firefighters and nearly all have eliminated women from the sample due to small sample size. Data from the present report is drawn from all females in a large, randomly selected cohort of firefighters in an epidemiological study designed to assess health outcomes and health risk behaviors identified as most important to the fire service. METHODS: Data reported for the present study were collected as baseline data for the Firefighter Injury and Risk Evaluation (FIRE) Study, a longitudinal cohort study examining risk factors for injury in both career and volunteer firefighters in the IAFC Missouri Valley Region. Of the departments assessed, only 8 career and 6 volunteer departments had any women firefighters. All the women solicited for participation chose to enroll in the study. The number of women ranged from 1 to 7 in career departments and 1 to 6 in volunteer departments. RESULTS: Where possible, comparisons are made between female firefighters and published data on male firefighters as well as comparisons between female firefighters and military members. Compared to male firefighters, females had more favorable body composition among both career and volunteer firefighters. Tobacco use rates were generally higher among females than males and rates among female firefighters were similar to the rates of female military members. While rates of alcohol use were higher than the general population, only one of the participants evidenced responses in the range of concern on the CAGE screening. CONCLUSIONS: In general, the findings offer an interesting glimpse of the health of women in the fire service as a generally healthy occupational workforce with some unique health risk behavior challenges. They also highlight some of the similarities and differences between male and female firefighters and bolster the argument for studying female firefighters as a unique occupational sub-population.

Military tobacco policies: the good, the bad, and the ugly.

The United States military has the legacy of a pro-tobacco culture and still has prevalence rates of tobacco use that are higher than their civilian counterparts. One tactic for decreasing use and the subsequent health problems is through effective tobacco control policies. We collected available tobacco control policies from all four branches of the military and, through qualitative analysis, identified policies that were unique either as providing more or less detail and restriction than peer group policies. Best and worst practice policies in the areas of enforcement, smoking cessation, smokeless tobacco use, environmental tobacco smoke, framing tobacco as non-normative, designated tobacco use areas, and monitoring of tobacco use are presented. Because policy making can be an effective tool for improving the health of military members, understanding what policy components are comparatively positive or negative is an important tool for health advocates both in the military and civilian settings.

The Census of Social Institutions (CSI): a public health direct observation measure of local land use.

This manuscript describes the development of the Census of Social Institutions (CSI), a reliable direct observation parcel-level built environment measure. The CSI was used to measure all non-residential parcels (n = 10,842) in 21 one-mile-radius neighborhoods centered around census block groups of varying income and ethnicity in a large metropolitan area. One year test-retest and inter-rater intra-class correlations showed high reliability for major use type and detail code observations. The CSI accurately captured the presence of about 9,500 uses, including 828 multiple major use and 431 mixed major use parcels that would have been missed in standard commercial databases. CSI data can be utilized to determine the health impacts of environmental settings.

Reported stress and its relationship to tobacco use among U.S. military personnel.

In addition to common stressors, members of the U.S. Armed Forces experience a high level of stress unique to their status as service members. In an effort to combat stress, many military personnel report high levels of nicotine use. This study investigated the relationship between tobacco use and perceived stress among military members in all four armed services. Results indicate that those who use tobacco products specifically to reduce stress report significantly higher stress levels than those who do not use tobacco. Moreover, current users and those who both smoked and used smokeless tobacco were far more likely to report experiencing "a lot" of stress from a variety of sources than former or never users. Tobacco users also engaged more frequently in negative coping behaviors and relied less on the positive coping strategies used more often by former or never smokers. These findings are consistent with the larger body of literature suggesting that tobacco is not only an ineffective stress-reducing strategy, it also likely perpetuates a stress response in users. It is, therefore, critical that the military improve effective means of coping among nicotine-using troops.

Relationship between patterns of alcohol use and negative alcohol-related outcomes among U.S. Air Force recruits.

The negative impact of alcohol use on workplace performance is of significant concern to the U.S. military, given the costs associated with recruiting, hiring, and training personnel. However, little is known about the extent of potential alcohol use problems of recruits. We examined the history of alcohol-related problems among recruits entering the Air Force (N=37858). Although the average age of recruits was <21 years, 78% reported consuming alcohol and 49% reported binging before basic military training. Recruits who drank reported having negative alcohol-related outcomes (NAROs). In fact, >95% reported that they or someone else had been injured as a result of their drinking and that a relative, friend, doctor, or other health care worker has been concerned about their drinking. The remaining NAROs were reported by approximately one-quarter of those who drank. However, recruits who reported binge drinking were substantially more likely to report more NAROs, such as morning drinking, inability to stop drinking, having others be concerned about their drinking, having blackouts, fighting, having injured or been injured, feeling guilty about their drinking, and wanting to reduce the amount they drink. Results suggest that alcohol-related problems are common among recruits before basic military training and screening for future problems may be beneficial.

Cigarette use among two cohorts of U.S. Air Force recruits, compared with secular trends.

This study provides a comparison of cigarette smoking among two cohorts of U.S. Air Force recruits. The first cohort, Air Force 1, entered the military between August 1995 and August 1996. The second cohort, Air Force 2, entered between October 1999 and September 2000. Cigarette use significantly increased among both men (7.0-percentage point increase) and women (7.3-percentage point increase) between the two cohorts. This difference remained statistically significant in models adjusted for demographic differences between the two groups of recruits. Direct standardization methods were then used to compare rates in both Air Force surveys with rates of current smoking reported for a national sample from the Behavioral Risk Factor Surveillance System surveys from the same years. Although the average number of cigarettes smoked and years of smoking decreased between the two cohorts, troops from Air Force 2 reported being less motivated to quit. This study suggests that efforts to reduce smoking among junior enlisted troops in the Air Force should be bolstered.

Saturation of tobacco smoking models and risk of alcohol and tobacco use among adolescents.

PURPOSE: To examine how saturation of an adolescent's environment with models of cigarette smoking (e.g., parents, siblings, friends) affects the probability of tobacco and alcohol use among junior high and high school students. METHODS: The Health and Smoking Questionnaire was administered to 806 adolescents (182 smokers and 624 nonsmokers; 57.2% female) average age of 15.1 years (SD = 1.6) in a mid-size Midwestern town. The questionnaire contains standardized items in five domains: demographics, smoking status and history, perceptions of risk and risk reduction, risk factors for tobacco use, and parenting style. RESULTS: Risk for smoking or using alcohol increased dramatically as the number of models who smoke increased in an adolescent's environment. For instance, adolescents with one significant other who smoked were nearly four times (OR = 3.76, p <.001) more likely to smoke than someone with no significant others who smoked. However, if an adolescent had four significant others who smoked, they were over 160 times more likely to smoke (OR = 161.25, p <.001). Similar results were found for alcohol use; adolescents who had one significant other who smoked were more than 2.5 (OR = 2.66, p <.001) times more likely to drink than those without smoking models. Adolescents who had four significant other smoking models were 13 times (OR = 13.08, p <.001) more likely to drink. CONCLUSIONS: As the number of cigarette smokers in an adolescent's environment increases, risk of tobacco and alcohol use increases substantially. These data suggest that multiple models of tobacco use will substantially increase risk for substance use in adolescents.

Impact of obesity on disease-specific health status after percutaneous coronary intervention in coronary disease patients.

OBJECTIVE: Several investigators have focused on obesity as a specific risk factor for mortality in patients undergoing bypass surgery, but few have examined it as a risk factor among patients undergoing percutaneous coronary interventions (PCI). In addition, none have evaluated the impact of obesity on post-PCI quality of life or disease-specific health status. This study examined whether obesity is a risk factor for poor quality of life or diminished health status 12-months postprocedure among a large cohort of PCI patients. RESEARCH METHODS AND PROCEDURES: A total of 1631 consecutive PCI patients were enrolled into the study and classified as underweight (BMI <20 kg/m2), normal weight range (BMI >/=20 and <25 kg/m2), overweight (BMI >/=25 and <30 kg/m2), class I obese (BMI >/=30 kg/m2), or class II and III obese (BMI >/=35 kg/m2). The 12-month postprocedure outcomes included need for repeat procedure, survival, quality of life and health status, assessed using the Seattle Angina Questionnaire (SAQ) and the Short Form-12. RESULTS: Obese patients with and without a history of revascularization were significantly younger than overweight, normal weight range, or underweight patients at the time of PCI. However, obese patients demonstrated similar long-term recovery and improved disease-specific health status and quality of life when compared to patients in the normal weight range after PCI. In addition, mortality and risk for repeat procedure was similar to those patients in the normal weight range patients at 12-months postrevascularization. Underweight patients who had no previous history of revascularization reported lower quality of life (F=3.02; P=0.018) and poorer physical functioning (F=2.82; P=0.024) than other BMI groups. CONCLUSION: Obese patients presenting for revascularization were younger when compared to patients in the normal weight range, regardless of previous history of revascularization. However, weight status was not a significant predictor of differences in long-term disease-specific health status, quality of life, repeat procedures, or survival. Underweight patients demonstrated less improvement in quality of life and physical functioning than other BMI groups.

Weight loss in obese Mexican Americans treated for 1-year with orlistat and lifestyle modification.

OBJECTIVE: To evaluate the effectiveness of a culturally appropriate lifestyle intervention combined with orlistat in producing weight loss with obese Mexican-American women. SUBJECTS: Mexican-American women (N=108), aged 21-65 y, with a body mass index (BMI) > or =27 kg/m(2) were randomized to 1 y of treatment with orlistat and a culturally tailored lifestyle modification intervention (OLM; n=56) or a wait-list control group (WLC; n=52). DESIGN: A randomized, controlled, open-label 12-month study. Orlistat was dosed at 120 mg, three times per day. The OLM intervention included behavior modification, a low-fat (< or =30% of total daily calories) diet, and moderate physical activity (> or =150 min/week). MEASUREMENT: Primary outcomes included changes in body weight (kg), BMI, waist circumference, blood pressure, glucose, and lipids. RESULTS: A total of 72 (37 OLM, 35 WLC) and 66 participants (32 OLM, 34 WLC) completed the 6- and 12-month follow-ups, respectively. Repeated-measures ANOVA demonstrated a significant time x treatment interaction (Wilks' lambda=12.61; P<0.001), indicating that OLM-treated patients achieved significant weight loss relative to the WLC group during the study (mean percentage weight loss+/-s.e.m.; -8.1%+/-1.2 vs -1.6%+/-0.7 at 6 months and -8.8%+/-1.5 vs -0.2%+/-1.0 at 12 months, respectively). OLM-treated patients also experienced significant reductions in waist circumference, low-density-lipoprotein, and total cholesterol. CONCLUSIONS: This study demonstrates the effectiveness of an intervention combining orlistat and lifestyle modification with Mexican-American women, a population with substantial risk for obesity.

Psychometric characteristics of the General Well-Being Schedule (GWB) with African-American women.

The General Well-Being Schedule (GWB) is a brief, reliable, and valid instrument used in population studies to assess psychological well-being, although its validity with African-Americans has yet to be established. This study evaluated the reliability, validity, and factor structure of the GWB in a sample of 599 overweight African-American women who participated in multicenter weight loss trial. The results of the factor analysis indicate that the GWB is primarily unidimensional and that the existence of the six hypothesized subscales was not supported. The GWB demonstrated evidence of concurrent and construct validity when examined in association with measures of self-concept, depression, and several health behaviors. The results of this study suggest that the GWB is a reliable and valid measure of psychological well-being in African-American women.

Childhood overweight: an expanding problem.

Childhood overweight is a significant and growing health problem in the US and other parts of the world. Secular trend data in the US suggest that children have become substantially heavier over the last several decades and that their risk for a number of health problems is increasing as a result. Defining obesity in children has been difficult as assessing body fat is expensive and impractical. Body mass index (BMI), derived from weight and height, is used as a surrogate indicator in adults. In children, the consensus is to use BMI percentiles statistically derived from a reference population. There is evidence that the prenatal, early childhood, and adolescent periods are critical in the development of obesity but the mechanisms involved are yet to be elucidated. The recent rapid increase in childhood overweight and obesity is attributed to the modern obesogenic environment. Changes in dietary constituents including higher derivation of energy from nutritionally poor and energy dense foods, increased sweetened drink consumption, larger portion sizes, and more frequent intake of food outside the home have been associated with poorer diets and higher weights. Further, physical activity has reduced with decreases in school physical education classes and organized sports, fewer opportunities to expend energy for daily living activity due to more mechanization, lower frequency of walking and biking, and greater use of sedentary activities for leisure. Television watching remains the most common activity for children. There are significant health outcomes associated with childhood obesity, including the presence of cardiovascular risk factors, and greater prevalence of various medical problems including insulin resistance, type 2 diabetes mellitus, the metabolic syndrome, orthopedic problems, and pseudotumor cerebri. Of further concern is the increased risk for obesity in adulthood with its attendant co-morbidities. Interventions are imperative but not widely studied. The most effective interventions include comprehensive behavioral management, dietary modification, and exercise. Family-based interventions have been most successful at maintaining long-term weight loss. School-based interventions have the potential to significantly impact childhood overweight as large numbers of children can be reached. However, such programs require long-term follow-up and are expensive. Very low calorie diets, pharmacotherapy, and surgery remain experimental options for children. More recently, metformin has shown promise in promoting weight loss and improving insulin sensitivity among adolescents. Combining multiple approaches for treatment, addressing obesity-promoting sociocultural practices and policies, and focusing on prevention strategies will be necessary to address this epidemic.
