RESUMO

OBJECTIVE: The purpose of this paper is to investigate intra-tour variation in total sleep time (TST) and sleep-wake cycle among US firefighters working the 24 hours on and 48 hours off shift schedule (24/48) and the 48 hours on and 96 hours off shift schedule (48/96). METHODS: Twenty-four firefighters were recruited for this sleep study and were evaluated over 18 days during a 24/48 shift schedule and again 6 months after firefighters transitioned to a 48/96 shift schedule. The primary outcome variables included TST, measured by actigraphy, and sleep-wake cycle (in-bed time and sleep offset) using the Emergency Services Sleep Diary. RESULTS: Firefighters experienced intra-tour variations in TST and sleep offset. The least TST occurred at home prior to starting shift on the 24/48 and 48/96 schedules (5.80 hours and 5.66 hours, respectively). The second least TST occurred the night preceding shift end (5.84 hours and 5.81 hours, respectively). In contrast to in-bed time, sleep offset varied throughout the schedule and was found to correlate with TST. In addition, shift start/end time appears to be responsible for advanced sleep offset. CONCLUSION: Results indicate that firefighters' sleep is complex and should not be reduced to singular averages. In both schedules, firefighters arrived at work with insufficient sleep, received insufficient sleep while on shift, and would commute home with insufficient sleep. These findings can inform future firefighter sleep research by accounting for intra-tour variations.

RESUMO

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.

RESUMO

BACKGROUND: Obesity is of increasing concern especially among firefighters. Bias in self-reported body weight, height and body mass index (BMI) has received a great deal of attention given its importance in epidemiological field research on obesity. AIMS: To determine the validity of self-reported weight, height and BMI and identify potential sources of bias in a national sample of US firefighters. METHODS: Self-reported and measured weight and height (and BMI derived from them) were assessed in a national sample of 1001 career male firefighters in the USA and errors in self-reported data were determined. RESULTS: There were 1001 participants. Self-reported weight, height and BMI were significantly correlated with their respective measured counterparts, i.e. measured weight (r = 0.990; P < 0.001), height (r = 0.961; P < 0.001) and BMI (r = 0.976; P < 0.001). The overall mean difference and standard deviation between self-reported weight, height and BMI were 1.3±2.0kg, 0.94±1.9cm and 0.09±0.9kg/m(2), respectively, for male firefighters. BMI-based weight status (P < 0.001) was the most consistent factor associated with bias in self-reported BMI, weight and height, with heavier firefighters more likely to underestimate their weight and overestimate their height, resulting in underestimated BMIs. Therefore, using self-reported BMI would have resulted in overestimating the prevalence of obesity (BMI ≥ 30.0) by 1.8%, but underestimating the prevalence of more serious levels of obesity (Class II and III) by 1.2%. CONCLUSIONS: Self-reported weight and height (and the resulting BMI) were highly correlated with measured values. A primary and consistent source of error in self-reported weight, height and BMI based on those indices was BMI-based weight status.

RESUMO

BACKGROUND: Overweight, obesity and weight gain are significant problems in the U.S. fire service. While classification of obesity using body mass index (BMI) has demonstrated accuracy and low rates of false positives when compared with body fat percentage (BF%)-based standards, no studies have examined the accuracy of BMI-based overweight and normal weight status with other comparable body composition indices. AIMS: To compare overweight and normal weight BMI categories with BF% standards from the American Council on Exercise and analogous waist circumference (WC) categories and to examine rates and types of misclassification in fire fighters. METHODS: Data were collected from 11 randomly selected career fire departments in the International Association of Fire Chief's Missouri Valley Region. Demographics, occupational history, and body composition indices (weight, BF% and WC) were obtained from male career fire fighters who were categorized as normal weight or overweight based on BMI. RESULTS: There were 293 participants of whom 92 had normal BMI. There were low rates of false positives (12%) and moderate rates of false negatives (22%) when comparing BMI categories to the compar able BF% categories. However, using WC as the standard resulted in very high rates of false positives (63%) and very low rates of false negatives (5%). CONCLUSIONS: BMI-based overweight status was associated with significant errors in classification depending on the standard to which it was compared.

RESUMO

INTRODUCTION: Firefighters currently have substantially lower smoking rates than similar occupational groups and the general U.S. population. In contrast, firefighters have very high rates of smokeless tobacco (SLT). The reasons for this paradox have not been explored; thus, the current study examined firefighters' perspectives on tobacco use. METHODS: Key informant interviews and focus groups were conducted in a national, cross-sectional purposively sampled group of 332 career firefighters. RESULTS: Firefighters suggested several reasons for the decline in smoking in the fire service including changes in the fire service culture, concerns about the impact of smoking on their ability to perform their job, regulations aimed at reducing smoking in departments, and the costs of smoking. In contrast, they felt that the greater use of SLT was primarily due to increasing restrictions on smoking. CONCLUSIONS: The primary reasons cited for decreased smoking rates by firefighters in our study were policy implementation at the state and local levels that prohibit tobacco use as a condition of employment and related presumption laws. However, reasons beyond policy mandates such as witnessing the end results of tobacco use, fitness, greater education about the negative health effects of smoking, and awareness about increased risk of exposure to toxic products of combustions also were noted. The primary reason cited for increased SLT use was the greater restrictions on smoking.

RESUMO

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.

RESUMO

BACKGROUND: Although the US National Fire Service is concerned about alcohol use among firefighters, little research has been conducted on the topic. AIMS: To survey alcohol use patterns among career and volunteer firefighters. METHODS: Data were from a population-based cohort study of male firefighters conducted in randomly selected career and volunteer departments. Data were collected from 2008 to 2010. RESULTS: There were 656 participants from 11 career and volunteer 13 departments included in the study with a response rate of 97%. Career firefighters drank approximately 10 days per month (just about half of their off duty days) and drank relatively heavily on those days. Fifty-eight per cent of career and 40% of volunteer firefighters averaged three or more drinks and similar percentages reported binge drinking on the days they consumed alcohol. In general, firefighters who drank but did not binge drink tended to have the best health outcomes, while those who binge drank typically were at highest risk of negative health outcomes. Nine per cent of career and 10% of volunteer firefighters who drank self-reported driving while intoxicated in the previous 30 days. CONCLUSIONS: Given the high rates of heavy and binge drinking, local and nationally coordinated efforts to increase the surveillance of drinking behaviour among firefighters and the development of targeted prevention interventions are critically needed.

RESUMO

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.

RESUMO

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.

RESUMO

Overweight and obesity are considered a serious health problem in Thailand. This study examined the prevalence of overweight and obesity in a nationally representative sample of Thai children and adults based on international standards. A cross-sectional population survey of 16,596 Thais aged 3 years and over was conducted. Heights and weights were obtained using standardized methods. Estimates of the overweight and obesity prevalence in children, adolescents, and adults were computed. The prevalence of overweight and obesity among children and adolescents aged 3 to 18 years was 7.6% and 9.0%, respectively, and was higher among boys than girls. Among adults, using the the Regional Office for the Western Pacific (WPRO) standard, 17.1% of adults were classified as overweight [body mass index (BMI) 23.0-24.9 kg/m²], 19.0% as class I obesity (BMI 25.0-29.9 kg/m²), and 4.8% as class II obesity (BMI ≥ 30.0 kg/m²). Using the World Health Organization (WHO) definition, 19.0% were overweight (BMI 25-29.9 kg/m²), 4.0% class I obesity (BMI 30.0-34.9 kg/m²), 0.8% class II obesity (BMI 35.0-39.9 kg/m²), and 0.1% class III obesity (BMI ≥ 40.0 kg/m²). There was a vast difference in obesity prevalence between the WHO and the WPRO criteria. Obesity prevalence when using the WPRO definition (23.8%) was almost five times greater than when defined with the WHO standard (4.9%). The present study found a high prevalence of overweight and obesity in nationally representative sample of the Thai population. Higher rates of overweight and obesity prevalence were computed using the WPRO standard when compared to the WHO standard.

RESUMO

Cigarette smoking is the leading preventable cause of death in the United States. Although smoking behavior has a significant genetic determination, the specific genes and associated mechanisms underlying the smoking behavior are largely unknown. Here, we carried out a genome-wide association study on smoking behavior in 840 Caucasians, including 417 males and 423 females, in which we examined approximately 380,000 single nucleotide polymorphisms (SNPs). We found that a cluster of nine SNPs upstream from the IL15 gene were associated with smoking status in males, with the most significant SNP, rs4956302, achieving a P-value (8.80 x 10(-8)) of genome-wide significance. Another SNP, rs17354547 that is highly conserved across multiple species achieved a P-value of 5.65 x 10(-5). These two SNPs, together with two additional SNPs (rs1402812 and rs4956396) were selected from the above nine SNPs for replication in an African-American sample containing 1251 subjects, including 412 males and 839 females. The SNP rs17354547 was replicated successfully in the male subgroup of the replication sample; it was associated with smoking quantity (SQ), the Heaviness of Smoking Index (HSI) and the Fagerstrom Test for Nicotine Dependence (FTND), with P-values of 0.031, 0.0046 and 0.019, respectively. In addition, a haplotype formed by rs17354547, rs1402812 and rs4956396 was also associated with SQ, HSI and FTND, achieving P-values of 0.039, 0.0093 and 0.0093, respectively. To further confirm our findings, we carried out an in silico replication study of the nine SNPs in a Framingham Heart Study sample containing 7623 Caucasians from 1731 families, among which, 3491 subjects were males and 4132 were females. Again, the male-specific association with smoking status was observed, for which seven of the nine SNPs achieved significant P-values (P<0.05) and two achieved marginally significant P-values (P<0.10) in males. Several of the nine SNPs, including the highly conserved one across species, rs17354547, are located at potential transcription factor binding sites, suggesting transcription regulation as a possible function for these SNPs. Through this function, the SNPs may modulate the gene expression of IL15, a key cytokine regulating immune function. As the immune system has long been recognized to influence drug addiction behavior, our association findings suggest a novel mechanism for smoking addiction involving immune modulation through the IL15 pathway.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

BACKGROUND: Most weight-loss research targets obese individuals who desire large weight reductions. However, evaluation of weight-gain prevention in overweight individuals is also critical as most Americans become obese as a result of a gradual gain of 1-2 pounds per year over many years. METHOD: This study evaluated the efficacy of an Internet-based program for weight-loss and weight-gain prevention with a two-group, prospective, randomized controlled trial. A military medical research center with a population of 17,000 active-duty military personnel supplied 446 overweight individuals (222 men; 224 women) with a mean age of 34 years and a mean BMI of 29. Recruitment and study participation occurred 2003-2005 and data were analyzed in 2006. Participants were randomly assigned to receive the 6-month behavioral Internet treatment (BIT, n=227) or usual care (n=224). Change in body weight, BMI, percent body fat, and waist circumference; presented as group by time interactions, were measured. RESULTS: After 6 months, completers who received BIT lost 1.3 kg while those assigned to usual care gained 0.6 kg (F((df=366))=24.17; I<0.001). Results were similar for the intention-to-treat model. BIT participants also had significant changes in BMI (-0.5 vs +0.2 kg/m(2); F((df=366))=24.58); percent body fat (-0.4 vs +0.6%; F((df=366))=10.45); and waist circumference (-2.1 vs -0.4 cm; F((df=366))=17.09); p<0.001 for all. CONCLUSIONS: Internet-based weight-management interventions result in small amounts of weight loss, prevent weight gain, and have potential for widespread dissemination as a population health approach. TRIAL REGISTRATION: NCT00417599.

RESUMO

OBJECTIVE: To assess parent behavioral change and perception of resident intervention on tobacco. METHODS: In a long-term study of the efficacy of training pediatric residents to address tobacco conducted at the New Jersey Medical School, sixteen pediatric training programs were assigned randomly to either special or standard training conditions. Parent surveys were administered in the fall of 2001 and 2005 in order to assess the effects of resident intervention on parent behavior, as well as parent perceptions of resident intervention. RESULTS: The percent of parents who smoke at sites associated with the special training condition, but not of those at sites associated with standard training, who reported that residents advised them to stop smoking, offered to help them quit, and provided quit smoking materials increased significantly from baseline to year 4. The percent of parents in the special training condition who reported quitting smoking in the past year also increased, although the increase was not statistically significant. A majority of the parents associated with each training condition reported receiving intervention for second hand smoke (SHS). For each training condition, the level of intervention to prevent exposure of infants and children to SHS exposure was similar at baseline and year 4, as was the percent of parents who reported having a smoke-free household. CONCLUSION: The results support the efficacy of the special training program and underscore the importance of preparing pediatric residents to address tobacco.

RESUMO

PURPOSE: To investigate sexually transmitted infection (STI) risk-taking behaviors relative to other lifestyle and risk-taking behaviors. DESIGN: The study design is cross sectional. SETTING: Lackland Air Force Base in San Antonio, Texas. SUBJECTS: Participants (N = 32,144) were 100% of Air Force recruits beginning basic military training from August 1995 to August 1996. MEASURES: Recruits completed a questionnaire that included rating the statement "Sex without condoms is sometimes worth the risk of possibly getting AIDS or sexually transmitted diseases." Risky behaviors, such as risk taking, rebelliousness, seat belt use, smoking, alcohol use and binge drinking, opinions of illicit drug use, and lifestyle behaviors, such as dietary intake and physical activity, were also assessed. ANALYSIS: Univariate and multivariate logistic regression analyses examined the relationships between participant characteristics and willingness to risk STI. RESULTS: Sixteen percent stated willingness to risk STI to have sex without a condom. Women and white/non-Hispanic participants were less likely to agree with the statement than men and minority participants. Those who reported willingness toward risky sexual behaviors were less likely to use seat belts, were more likely to binge drink, had more positive views of illicit drugs, and reported eating fewer fruits and vegetables. CONCLUSION: Results of this study suggest the importance of continued education on condom use and the possibility that multiple risk behavior interventions include sexual risk components.
