Occupationally Tailored, Web-Based, Nutrition and Physical Activity Program for Firefighters: Cluster Randomized Trial and Weight Outcome.

OBJECTIVE: The aim of this study was to determine the efficacy of an occupationally tailored, web-based health and wellness program, The First Twenty® (TF20), for weight change among volunteer firefighters. METHODS: The impact of TF20 on firefighters' 6-month weight change was tested in a cluster, randomized controlled trial, using a crossover design of firefighters in 10 departments. TF20 has web-based nutrition, physical activity, and behavioral health components. RESULTS: An adjusted treatment-induced weight loss from 1.7 to 2.8 lb was observed for all participants and 2.3 to 3.1 lb among overweight and obese participants. An average weight gain was observed among firefighters in the control condition and weight loss for those in the treatment condition. CONCLUSIONS: TF20 supports firefighters' weight loss. Firefighters need wellness interventions to improve nutrition and physical activity given their high prevalence of obesity.

Current Female Firefighters' Perceptions, Attitudes, and Experiences with Injury.

Research presented here examines how the demands of fire fighting uniquely affect women. A national sample of 73 female firefighters and fire-service leaders participated in focus groups and key informant interviews. Participants were asked about perceived threats to safety and standard operating procedures (SOPs) that lead to injury regarding gender differences. A thematic qualitative analysis was conducted and the following six themes were identified: (1) impact of working in a male-dominated field, (2) harassment, (3) similar rates/types of injury, (4) inadequate training, (5) ill-fitting gear, and (6) functional techniques/endurance. Both chronic and acute injuries/causes were discussed. Future direction will require diversity education and new training methodologies for the fire service.

Weight Advice Associated With Male Firefighter Weight Perception and Behavior.

INTRODUCTION: The high prevalence of overweight and obesity threatens the health and safety of the fire service. Healthcare professionals may play an important role in helping firefighters achieve a healthy weight by providing weight loss counseling to at-risk firefighters. This study characterizes the impact of healthcare professional weight loss advice on firefighter weight perceptions and weight loss behaviors among overweight and obese male firefighters. METHODS: A national sample of 763 overweight and obese male firefighters who recalled visiting a healthcare provider in the past 12 months reported information regarding healthcare visits, weight perceptions, current weight loss behaviors, and other covariates in 2011-2012. Analyzed in 2013, four unique multilevel logistic regression models estimated the association between healthcare professional weight loss advice and the outcomes of firefighter-reported weight perceptions, intentions to lose weight, reduced caloric intake, and increased physical activity. RESULTS: Healthcare professional weight loss advice was significantly associated with self-perception as overweight (OR=4.78, 95% CI=2.16, 10.57) and attempted weight loss (OR=2.06, 95% CI=1.25, 3.38), but not significantly associated with reduced caloric intake (OR=1.26, 95% CI=0.82, 1.95) and increased physical activity (OR=1.51, 95% CI=0.89, 2.61), after adjusting for confounders. CONCLUSIONS: Healthcare professional weight loss advice appears to increase the accuracy of firefighter weight perceptions, promote weight loss attempts, and may encourage dieting and physical activity behaviors among overweight firefighters. Healthcare providers should acknowledge their ability to influence the health behaviors of overweight and obese patients and make efforts to increase the quality and frequency of weight loss recommendations for all firefighters.

Findings from an online behavioural weight management programme provided with or without a fortified diet beverage.

The present multi-centre randomised weight-loss trial evaluated the efficacy of a low-intensity 12-week online behavioural modification programme, with or without a fortified diet beverage using a 2 × 2 factorial design. A total of 572 participants were randomised to: (1) an online basic lifestyle information (OBLI) intervention, consisting of one online informational class about tips for weight management; (2) an online behavioural weight management (OBWM) intervention, entailing 12 weekly online classes focused on weight-loss behaviour modification; (3) an OBLI intervention plus a fortified diet cola beverage (BEV) containing green tea extract (total catechin 167 mg), soluble fibre dextrin (10 g) and caffeine (100 mg) (OBLI+BEV); (4) OBWM+BEV. Assessments included height, weight, dual-energy X-ray absorptiometry-derived body composition, and waist circumference (WC). Attrition was 15·7 %. Intention-to-treat (ITT) models demonstrated a main effect for type of Internet programme, with those assigned to the OBWM condition losing significantly more weight (F= 7·174; P= 0·008) and fat mass (F= 4·491; P= 0·035) than those assigned to the OBLI condition. However, there was no significant main effect for the OBWM condition on body fat percentage (F= 2·906; P= 0·089) or WC (F= 3·351; P= 0·068), and no significant main effect for beverage use or significant interactions between factors in ITT models. A 12-week, low-intensity behaviourally based online programme produced a greater weight loss than a basic information website. The addition of a fortified diet beverage had no additional impact.

Excessive daytime sleepiness in firefighters in the central United States.

OBJECTIVE: To determine the prevalence and severity of excessive daytime sleepiness (EDS) in a population-based sample of firefighters. METHODS: Sleepiness was assessed using the Epworth Sleepiness Scale in a sample of male career firefighters (n = 458) from 11 randomly selected fire departments in the Midwestern United States. RESULTS: Unadjusted EDS rates (13.7% and 14.0% for on- and off-duty, respectively) were similar to the general US population and comparable occupational groups. Factors associated with EDS included 48-hour work shifts, non-private department sleep areas, and working a second job outside the fire service (P < 0.05). CONCLUSION: Given firefighters' important role in public safety, concerns have been raised about whether firefighters' work schedules result in high rates of excessive sleepiness. Nevertheless, firefighters in this study did not have high rates of EDS despite their extended work schedule.

Health concerns of the U.S. fire service: perspectives from the firehouse.

PURPOSE: Firefighters are expected to respond to any domestic emergency at a moment's notice, and therefore their health and readiness are key to the public safety net. Although emerging research is focusing on understanding firefighters' increased risk for disease and injury, the perspectives of fire service personnel is lacking. DESIGN: This study uses the cross-sectional qualitative data collection techniques of key informant interviews and focus groups. SETTING: Data collection occurred with a national sample of firefighters from 28 (municipal and federal) career fire departments. PARTICIPANTS: Participants were 332 career firefighters (57.2%), company officers (23.4%), fire chiefs (15.4%), and other fire service personnel (3.9%). METHOD: Focus groups and informant interviews were conducted with firefighters, fire chiefs, health promotion personnel, and medical directors to assess attitudes, opinions, and perceptions about firefighter health. RESULTS: Major themes that developed among fire service personnel included concerns about cancer, risk of cardiovascular disease, the importance of and barriers to physical fitness, the food culture of the firehouse, psychological stress resulting from repeated exposure to trauma, sleep disruptions, injuries, and risk for infectious disease. Health concerns identified by firefighters are juxtaposed with current efforts and trends within the national fire service. CONCLUSIONS: The health concerns of firefighters parallel both available epidemiological research and the health priorities of national fire service organizations. Unfortunately, these concerns often are in contrast with efforts by local governments to limit their financial liability for illnesses presumed to be caused by occupational exposures and long-held traditions in the fire service. This study highlights the need for epidemiological surveillance of firefighters and innovative health and organizational policy in the fire service. Future directions for the fire service, the public health community, and researchers are discussed.

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.

The impact of surveillance on weight change and predictors of change in a population-based firefighter cohort.

OBJECTIVE: To document weight changes in a population-based cohort of male career firefighters and evaluate the impact of health surveillance on subsequent participant behavior and body composition. METHODS: Body mass index, waist circumference, and body fat percentage were assessed longitudinally in 311 male firefighters. RESULTS: Firefighters who reported making no changes after the baseline assessment (42.1%) experienced a 0.64 ± 3.1 kg average weight gain, whereas firefighters who reported making one or more health behavior change (ie, changing their diet, increasing their physical activity, or both; 52.1%) lost an average of -1.3 kg. CONCLUSIONS: Regular health surveillance may motivate some firefighters to make health behavior changes. Although it is not currently the norm, fire departments should provide firefighters with annual health assessments including body composition and fitness measures, consistent with those recommended by the fire service's Wellness and Fitness Initiative.

Obesity and injury-related absenteeism in a population-based firefighter cohort.

A consistent relationship has been demonstrated between obesity and absenteeism in the workplace. However, most studies have focused on primarily sedentary occupational groups. Firefighting is a physically demanding profession that involves significant potential for exposure to dangerous situations and strenuous work. No studies to date have evaluated the impact of obesity on risk for absenteeism among firefighters. We examined the cross-sectional association between BMI and obesity and injury-related absenteeism. BMI, body fat percentage (BF%), waist circumference (WC), injury, and injury-related absenteeism were assessed in 478 career male firefighters. One hundred and fifteen firefighters reported an injury in the previous year and the number of days absent from work due to their injury. BMI was an independent predictor of absenteeism due to injury even after adjustment for confounding variables. Firefighters meeting the definition of class II and III obesity had nearly five times (odds ratio (OR) = 4.89; 95% confidence interval (CI) = 3.63-6.58) the number missed work days due to injury when compared to their normal weight counterparts and their elevated risk was greater than firefighters with class I obesity (OR = 2.71; 95% CI = 2.01-3.65) or those who were overweight (OR = 2.55; 95% CI = 1.90-3.41). The attributable per capita costs of class II and III obesity-related absenteeism over the last year were $1,682.90 per firefighter, $254.00 per firefighter for class I obesity, and $74.41 per firefighter for overweight. Our findings suggest that class II and III obesity were associated with substantial attributable costs to employers and our cost estimates probably underestimate the actual financial burden.

Tobacco use among firefighters in the central United States.

BACKGROUND: This study provides a comprehensive, population-based examination of tobacco use among both career and volunteer firefighters. METHODS: Data are from a population-based cohort study of randomly selected career (N = 11) and volunteer (N = 13) departments comprised of 677 male firefighters. RESULTS: Unadjusted rates of smoking were 13.6% and 17.4% for career and volunteer firefighters, respectively. Smoking rates were less than a comparable occupational group (military personnel) and adult males in the states represented. Smokers were more likely to have been diagnosed with an anxiety disorder (OR = 5.8; P = 0.010), have an elevated CAGE alcohol problem score (OR = 2.9; P = 0.040), and more likely to report driving after drinking too much (OR = 4.5; P = 0.020) compared to never-smokers. Large percentages of career (18.4%) and volunteer (16.8%) firefighters used smokeless tobacco. CONCLUSIONS Smoking among firefighters is associated with other significant health and safety risks. High rates of smokeless tobacco use suggest that the fire service is an important target for intervention. Thus, despite strong statements against smoking by the fire service, the need to maintain high levels of health and fitness and relatively low smoking rates, a significant proportion of firefighters continue to use tobacco products.

The prevalence of overweight, obesity, and substandard fitness in a population-based firefighter cohort.

OBJECTIVE: To examine the prevalence of overweight and obesity in firefighters. METHODS: Body mass index (BMI), waist circumference, and body fat percentage (BF%) were assessed in 478 career and 199 volunteer male firefighters from randomly selected departments. RESULTS: High prevalence rates of overweight + obesity (BMI ≥ 25 kg/m) and obesity (BMI ≥ 30 kg/m) were found in career (79.5%; 33.5%) and volunteer firefighters (78.4%; 43.2%). False-positive obesity misclassification based on BMI, compared to waist circumference and BF%, was low (9.8% and 2.9%, respectively). False negatives were much higher: 32.9% and 13.0%. Obese firefighters demonstrated unfavorable cardiovascular disease (CVD) profiles. CONCLUSIONS: The prevalence of overweight and obesity exceeded that of the US general population. Contrary to common wisdom, obesity was even more prevalent when assessed by BF% than by BMI, and misclassifying muscular firefighters as obese by using BMI occurred infrequently.

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 use of a commercial vegetable juice as a practical means to increase vegetable intake: a randomized controlled trial.

BACKGROUND: Recommendations for daily dietary vegetable intake were increased in the 2005 USDA Dietary Guidelines as consumption of a diet rich in vegetables has been associated with lower risk of certain chronic health disorders including cardiovascular disease. However, vegetable consumption in the United States has declined over the past decade; consequently, the gap between dietary recommendations and vegetable intake is widening. The primary aim of this study is to determine if drinking vegetable juice is a practical way to help meet daily dietary recommendations for vegetable intake consistent with the 2005 Dietary Guidelines and the Dietary Approaches to Stop Hypertension (DASH) diet. The secondary aim is to assess the effect of a vegetable juice on measures of cardiovascular health. METHODS: We conducted a 12-week, randomized, controlled, parallel-arm study consisting of 3 groups of free-living, healthy volunteers who participated in study visits at the Ragle Human Nutrition Research Center at the University of California, Davis. All subjects received education on the DASH diet and 0, 8 or 16 fluid ounces of vegetable juice daily. Assessments were completed of daily vegetable servings before and after incorporation of vegetable juice and cardiovascular health parameters including blood pressure. RESULTS: Without the juice, vegetable intake in all groups was lower than the 2005 Dietary Guidelines and DASH diet recommendations. The consumption of the vegetable juice helped participants reach recommended intake. In general, parameters associated with cardiovascular health did not change over time. However, in the vegetable juice intervention groups, subjects who were pre-hypertensive at the start of the study showed a significant decrease in blood pressure during the 12-week intervention period. CONCLUSION: Including 1-2 cups of vegetable juice daily was an effective and acceptable way for healthy adults to close the dietary vegetable gap. Increase in daily vegetable intake was associated with a reduction in blood pressure in subjects who were pre-hypertensive at the start of the trial. TRIAL REGISTRATION: Clinicaltrials.gov NCT01161706.

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.

Weight loss in individuals with metabolic syndrome given DASH diet counseling when provided a low sodium vegetable juice: a randomized controlled trial.

BACKGROUND: Metabolic syndrome, a constellation of metabolic risk factors for type 2 diabetes and cardiovascular disease, is one of the fastest growing disease entities in the world. Weight loss is thought to be a key to improving all aspects of metabolic syndrome. Research studies have suggested benefits from diets rich in vegetables and fruits in helping individuals reach and achieve healthy weights. OBJECTIVE: To evaluate the effects of a ready to serve vegetable juice as part of a calorie-appropriate Dietary Approaches to Stop Hypertension (DASH) diet in an ethnically diverse population of people with Metabolic Syndrome on weight loss and their ability to meet vegetable intake recommendations, and on their clinical characteristics of metabolic syndrome (waist circumference, triglycerides, HDL, fasting blood glucose and blood pressure).A secondary goal was to examine the impact of the vegetable juice on associated parameters, including leptin, vascular adhesion markers, and markers of the oxidative defense system and of oxidative stress. METHODS: A prospective 12 week, 3 group (0, 8, or 16 fluid ounces of low sodium vegetable juice) parallel arm randomized controlled trial. Participants were requested to limit their calorie intake to 1600 kcals for women and 1800 kcals for men and were educated on the DASH diet. A total of 81 (22 men & 59 women) participants with Metabolic Syndrome were enrolled into the study. Dietary nutrient and vegetable intake, weight, height, leptin, metabolic syndrome clinical characteristics and related markers of endothelial and cardiovascular health were measured at baseline, 6-, and 12-weeks. RESULTS: There were significant group by time interactions when aggregating both groups consuming vegetable juice (8 or 16 fluid ounces daily). Those consuming juice lost more weight, consumed more Vitamin C, potassium, and dietary vegetables than individuals who were in the group that only received diet counseling (p < 0.05). CONCLUSION: The incorporation of vegetable juice into the daily diet can be a simple and effective way to increase the number of daily vegetable servings. Data from this study also suggest the potential of using a low sodium vegetable juice in conjunction with a calorie restricted diet to aid in weight loss in overweight individuals with metabolic syndrome.

A qualitative analysis of the tobacco control climate in the U.S. military.

INTRODUCTION: Rates of tobacco use in the U.S. military have traditionally been higher than in the general U.S. population. While the military has experienced decreases in tobacco use over the past two decades, recent surveys suggest a trend of increased use. Given the negative impact of tobacco on both the readiness and the long-term health of military members, it is important to understand what factors may be related to the increased use rates. It has been suggested that there is a culture that supports tobacco use in the military. METHODS: We examined perceptions about the climate of tobacco control among military installation Tobacco Control Managers and Service Policy Leaders from all four branches of the military (n = 52) using semistructured interviews. RESULTS: The primary strength of the military's tobacco control program, according to the participants, was mandating the provision of treatment services on every military installation. Any military member can receive both counseling and pharmacotherapy for tobacco. Opinions vary on the most promising new strategies for tobacco control. Many have pushed for a completely tobacco-free Department of Defense, including requiring troops to be tobacco-free and banning tobacco sales on military installations. However, a number of tobacco control experts within the military worry about unintended consequences of a complete ban. DISCUSSION: While several benefits of the current tobacco control program were identified, opportunities for improvement were identified at both the installation and service level.

Effects of a school-based weight maintenance program for Mexican-American children: results at 2 years.

The prevalence of childhood overweight has increased significantly, with the highest rates noted among Mexican Americans. Many negative health outcomes are associated with overweight; thus, there is a need for effective weight-loss interventions tailored to this group. This study evaluated 24-month outcomes of a randomized, controlled trial involving an intensive lifestyle-based weight maintenance program targeting overweight Mexican-American children at a charter school in Houston, Texas. A total of 60 children (33 males, 55%) between the ages of 10 and 14 at or >85th percentile for BMI were recruited. Participants were randomized to an instructor-led intervention (ILI) or a self-help (SH) program, both aimed at modifying eating and physical activity behaviors using behavior modification strategies. Changes in participants' standardized BMI (zBMI) were assessed at baseline, 1, and 2 years. Tricep skinfold, total cholesterol, triglycerides, high-density lipoprotein cholesterol, and calculated low-density lipoprotein were assessed at baseline and 1 year. ILI participants showed significantly greater decreases in zBMI at 1 and 2 years (F = 26.8, P < 0.001, F = 4.1, P < 0.05, respectively) compared to SH controls. ILI participants showed greater improvements in body composition, as measured by tricep skinfold (F = 9.75, P < 0.01). Children in the ILI condition experienced benefits with respect to total cholesterol (F = 7.19, P < 0.05) and triglycerides (F = 4.35, P < 0.05) compared to children in the SH condition. Overall, the school-based intervention resulted in improved weight and clinical outcomes in overweight Mexican-American children, and zBMI was maintained over 2 years.

The impact of smoking status on the health status of heart failure patients.

Smoking is a major risk factor for the development of heart failure (HF). Yet, little is known about smoking's effects on the health status of established HF patients. HF patients were recruited from outpatient clinics across North America. The Kansas City Cardiomyopathy Questionnaire (KCCQ) was used to assess disease-specific health status. Smoking behaviors were classified as never having smoked, prior smoker, and as having smoked within the past 30 days. Risk-adjusted multivariable regression was used to evaluate the association of smoking status with baseline and 1-year KCCQ overall summary scores. Smoking was not associated with baseline health status. However, a significant effect was observed on 1-year health status among outpatients with HF with current smokers reporting significantly lower KCCQ scores than never smokers or ex-smokers. These findings highlight an additional adverse consequence of smoking in HF patients not previously discussed.

Factors which influence tobacco use among junior enlisted personnel in the United States Army and Air Force: a formative research study.

BACKGROUND: Despite the implementation of a host of tobacco control initiatives, tobacco use among active duty members of the U.S. Military remains high. It has been suggested that a positive culture of tobacco, which drives consumption, exists in the military. However, little is know about factors that impact tobacco use among military personnel. OBJECTIVE: This study provides the first formative data on the culture of tobacco in the U.S. Military. METHODS: A total of 15 focus groups on six military installations were conducted (n = 189). These military installations were located throughout the continental United States and were of average size for each service. RESULTS: Participants suggested that the primary method the military uses to discourage use is tobacco bans. Unfortunately, they also believed that the military accommodates tobacco use so that smoking remains convenient despite the bans on tobacco use. Smoking was believed to be encouraged through liberal smoking breaks, social interaction within designated smoking areas, and cheap and convenient tobacco products sold on military installations. Additionally, smoking was seen as an effective method to combat the stress and boredom of military life and to avoid weight gain. CONCLUSIONS: Suggestions for addressing the culture of tobacco are suggested.

The relationship between smoking, BMI, physical activity, and dietary intake among Thai adults in central Thailand.

OBJECTIVE: Evaluate dietary intake, physical activity, and BMI in adult Thais stratified by smoking status, living in the central region of Thailand. MATERIAL AND METHOD: Participants (n = 1,027) were administered a health questionnaires, 24-h dietary recall, and anthropometric measurements were obtained. RESULTS: Compared to ex-smokers (24.5 +/- 4.3 kg/m2) and non-smokers (24.8 +/- 4.0 kg/m2), current smokers (22.6 +/- 3.8 kg/m2) had significantly lower BMIs, regardless of gender (p < 0.001). In addition, male smokers had smaller waist circumferences than non-smokers. There were no statistically significant differences in nutrient intake or physical activity based on smoking status. Results from this study are consistent with others reports showing that smoking is associated with lower weights and BMI when compared to non-smokers. The mechanism for this association may be related to the potential for nicotine to increase metabolic rate rather than appetite suppression in smokers. CONCLUSION: Because the substantial negative health consequences of smoking are far stronger than those associated with modest weight differences, smoking cannot be viewed as an appropriate weight management strategy.
