Trends in Tobacco Use among Young Adults Presenting for Military Service in the United States Air Force between 2013 and 2018

Tobacco and nicotine use among active component U.S. military service members: a comparison of 2018 estimates from the Health Related Behaviors Survey and the Periodic Health Assessment

This study compared estimates of the prevalence of and risk factors for tobacco and nicotine use obtained from the 2018 Health Related Behaviors Survey (HRBS) and Periodic Health Assessment (PHA) survey. The HRBS and the PHA are important Department of Defense sources of data on health behavior collected from U.S. military service members. While their collection methods differ, some survey questions are similar, which provides an opportunity to compare survey estimates. Active duty service members consistently reported a much lower prevalence of all types of tobacco and nicotine use on the PHA compared to the HRBS: cigarettes (11.1% vs. 18.4%), e-cigarettes (7.3% vs. 16.2%), chewing tobacco (9.7% vs. 13.4%), any tobacco or nicotine use (25.3% vs. 37.8%), and use of 2 or more tobacco or nicotine products (5.8% vs. 17.4%). Associations between tobacco and nicotine use as well as demographic and other behavioral variables were fairly similar, including age, sex, education, race and ethnicity, rank, and alcohol use. The associations with service branch, body mass index, and sleep were inconsistent. This results of this study suggest that the PHA can provide timely information on trends in military tobacco and nicotine use over time, but much higher estimates from the confidential, voluntary HRBS reported in this study suggest that the command-directed PHA may substantially underestimate the prevalence of all types of tobacco and nicotine use.

The Burden and Correlates of Waterpipe (Hookah) Smoking among Adolescents and Youth: A Systematic Review

BACKGROUND

This systematic review evaluated the available medical literature on the prevalence and trends of waterpipe tobacco smoking among adolescents and youth in jurisdictionally representative populations.

METHODS

PubMed, Embase, and Scopus were searched for relevant studies from inception until 31 December 2022 that reported the burden of waterpipe smoking among adolescents and youth (10-24 years of age). We extracted qualitative data on the demographic characteristics, burden, and correlates of waterpipe smoking (PROSPERO ID: CRD42022310982).

RESULTS

A total of 2,197 articles were screened and 62 were included in the analysis. The majority (29) of the studies was from the United States of America and there were no studies from the south-east Asian region. The prevalence of ever waterpipe smoking among the 10-24 years age group was noted to be 18.16% (95% CI, 18.03-18.29). The prevalence of current (30-day) waterpipe smoking was 6.43% (95% CI, 6.34-6.50). The age of initiation of waterpipe smoking was variable. The prevalence of waterpipe smoking was higher among males, among those who belong to the high- and middle-income groups, and among university students. The common risk factors of waterpipe smoking included cigarette smoking, alcohol, and substance use. Waterpipe smoking resulted in increased susceptibility to the use of conventional forms of tobacco (e.g. smoking) among those who were never smokers.

CONCLUSION

Waterpipe smoking usage was significantly high among adolescents and young adults. Developing regulatory guidelines for water-pipe smoking, surveillance of its use, intervention, and specific policy frameworks may be considered a public health priority.

Motives for using electronic nicotine delivery systems (ENDS) as a cessation tool are associated with tobacco abstinence at 1-year follow-up: A prospective investigation among young adults in the United States Air Force

Introduction

Smokers use electronic nicotine delivery systems (ENDS), including e-cigarettes, as a harm reduction strategy even though the Food and Drug Administration (FDA) has not approved them for tobacco cessation. The limited literature about ENDS use for cigarette cessation is concerning for the U.S. military, which is largely comprised of young adults at increased risk for tobacco use. Thus, the current study aims to evaluate use of ENDS products as a cessation tool in relation to point-prevalence tobacco abstinence at one-year follow-up in a cohort of 8,901 U.S. Air Force personnel attending entry-level job training from March 2016 to April 2019.

Methods

A propensity-score adjusted multinomial logistic regression model was used to assess the association between the baseline motives for ENDS use (i.e., for cigarette cessation versus alternative reasons) and tobacco use at the one-year follow-up (cigarette use, non-cigarette tobacco product use, and tobacco abstinence) among those reporting history of cigarette use at baseline.

Results

Smokers reporting ENDS use for cigarette cessation were more likely to be abstinent at one-year follow-up (Odds Ratio[OR] = 1.62, 95% CI: 1.06-2.49, P =.03) as well as quit using non-cigarette tobacco products (OR = 2.11, 95% CI: 1.65-2.70, P <.001) than those reporting ENDS use for alternative reasons.

Conclusions

Current tobacco users are recommended to use FDA-approved products for smoking cessation, such as nicotine replacement therapy. However, given the high prevalence of cigarette use among military populations, ENDS may provide a useful alternative harm reduction strategy for this high-risk population.

Decreasing alcohol use among young adults presenting for service in the U.S. Air Force: An epidemiological surveillance study

U.S. surveys demonstrate recent decreases in the prevalence of alcohol use and binge drinking among young adults. The current study aims to determine whether similar trends are evident in a similarly aged cohort of service members in the US Air Force to inform ongoing prevention efforts. Participants were 103,240 Air Force personnel in entry-level training between 2016 and 2019. Participants anonymously completed the AUDIT (Alcohol Use Disorder Identification Test) regarding their pre-service drinking. Logistic regression analyses and the Cochran-Armitage test were conducted to measure population trends over the study duration with stratification by age (<21 vs. ≥21) and evaluation of specific alcohol behaviors. Between 2016 and 2019, the proportion of young service members endorsing any alcohol use significantly decreased for both the <21 group (i.e. from 38.9% to 32.6%) and the ≥21 group (i.e. from 80.6% to 77.5%). Among those who endorsed drinking, a decrease over time in binge use was also observed from 46.6% to 37.8% for the <21 group and from 34.2% to 27.5% for the ≥21 group. Responses to other specific alcohol risk items and total AUDIT scores also demonstrated decreases. Binge use and risky drinking remained disproportionately common among those under the legal drinking age. It is encouraging to observe a shift toward abstinence and decreased binge use among this population of young military recruits. However, given the risk for many adverse health and legal consequences in this population, more work is needed to prevent problematic drinking, especially among those under the legal drinking age.

Sexy, trashy, cool: Perceptions of electronic cigarette users across sociodemographic groups and E-cigarette use among United States Air Force Airmen

E-cigarette use has increased in recent years. Military personnel have higher rates of e-cigarette use than civilian populations, with 15.3% of Air Force recruits using e-cigarettes. The current study assessed associations between perceptions of e-cigarette users and current use of e-cigarettes, and differences in sociodemographic characteristics to determine if there were different beliefs among different groups to inform intervention development among these straight-to-work young adults. Participants (N = 17,314) were United States Air Force Airmen (60.7% White, 29.7% women) who completed a survey during their first week of Technical Training. Regression results indicated that identifying as a man (B = 0.22, SE = 0.02), identifying as Black (B = 0.06, SE = 0.02), reporting younger age (B = -0.15, SE = 0.02), having less education (B = -0.04, SE = 0.02), and current e-cigarette use (B = 0.62, SE = 0.02) were associated with endorsing more positive e-cigarette user perceptions. Identifying as a woman (B = -0.04, SE = 0.02) and being younger (B = -0.06, SE = 0.02) were associated with endorsing more negative perceptions of e-cigarette users. Current e-cigarette use was inversely associated with negative e-cigarette user perceptions (B = -0.59, SE = 0.02). Differences across groups were found for individual e-cigarette user characteristics. Future intervention strategies among Airmen may benefit from addressing e-cigarette user perceptions to change use behaviors, as these perceptions may result in stigmatized beliefs related to e-cigarette users.

Motives of Tobacco Use Among Young Adults in the United States Air Force

PURPOSE

Research has focused on cigarette use motives and have not included military personnel. The current study assessed tobacco use motives for different products, and differences within males and females and those with different racial identities given historical disparities in tobacco use.

DESIGN

A cross-sectional survey about tobacco use was administered from October 2019 to February 2022.

SETTING

Four Technical Training bases in the US.

SAMPLE

Air Force Airmen who used tobacco (N = 3243).

MEASURES

Questions were about sociodemographic characteristics, tobacco use, and the Tobacco Motives Inventory (representing affect regulation, boredom, enhancement, and social motives).

ANALYSIS

Linear regressions assessed associations between overall tobacco use and motives. Stratified analyses assessed associations between tobacco use and motives among males and females, and individuals from different racial backgrounds. Logistic regressions assessed differences in motives and use of different tobacco products between "some day" and "everyday" users.

RESULTS

Overall, boredom (B = .09, SE = .01) and affect regulation (B = .05, SE = .00) motives were associated with higher tobacco use. Males and females and individuals from different racial backgrounds endorsed different motives, but all endorsed boredom as a motive for higher tobacco use. Individuals who used cigarettes, e-cigarettes, or smokeless tobacco "some days" endorsed higher social motives than everyday users, but everyday users endorsed different motives across products.

CONCLUSION

There are motives differentiating between "some day" and "everyday" users of tobacco products, which may need to be differentially targeted in intervention programs. Additionally, there are some overlapping motives (affect regulation, boredom) that may be beneficial to address with all tobacco users.

Musculoskeletal injuries in US Air Force Tactical Air Control Party trainees: an 11-year longitudinal retrospective cohort study and presentation of a musculoskeletal injury classification matrix

INTRODUCTION

Little is known of the epidemiology of musculoskeletal injuries (MSKIs) in US Air Force Special Warfare (AFSPECWAR) Tactical Air Control Party trainees. The purpose of this longitudinal retrospective cohort study was to (1) report the incidence and type of MSKI sustained by AFSPECWAR trainees during and up to 1 year following training, (2) identify factors associated with MSKI, and (3) develop and present the MSKI classification matrix used to identify and categorise injuries in this study.

METHODS

Trainees in the Tactical Air Control Party Apprentice Course between fiscal years 2010-2020 were included. Diagnosis codes were classified as MSKI or non-MSKI using a classification matrix. Incidence rates and incidence proportion for injury types and regions were calculated. Measures were compared for differences between those who did and did not sustain an MSKI during training. A Cox proportional hazards model was used to identify factors associated with MSKI.

RESULTS

Of the 3242 trainees, 1588 (49%) sustained an MSKI during training and the cohort sustained MSKIs at a rate of 16 MSKI per 100 person-months. Overuse/non-specific lower extremity injuries predominated. Differences were seen in some baseline measures between those who did and did not sustain an MSKI. Factors retained in the final Cox regression model were age, 1.5-mile run times and prior MSKI.

CONCLUSION

Slower run times and higher age were associated with an increased likelihood of MSKI. Prior MSKI was the strongest predictor of MSKI during training. Trainees sustained MSKIs at a higher rate than graduates in their first year in the career field. The MSKI matrix was effective in identifying and categorising MSKI over a prolonged (12-year) surveillance period and could be useful for future injury surveillance efforts in the military or civilian settings. Findings from this study could inform future injury mitigation efforts in military training environments.

Examination of Tobacco-Related Messaging and Tobacco Use over Time among U.S. Military Young Adults

Background: People from minoritized populations have historically been targeted by tobacco companies. Little is known about exposure to tobacco-related messages among military personnel from disadvantaged backgrounds. Objectives: The current study aimed to examine exposure to tobacco-related messaging across many nicotine products and through a variety of mediums (i.e., family, friends, advertisements, event promotions, social media) among diverse military populations and use one year later in a sample of young adults who recently enlisted in the U.S. Air Force. Methods: In this study, 8,901 U.S. Air Force trainees reported on demographics, tobacco use, and exposure to positive tobacco messages from social sources (i.e., friends, family, social media) and environmental sources (i.e., advertisements and promotions). Tobacco use was reported one-year later. Results: Compared to others of the same reported racial/ethnic background, Latino/a/x (Relative Risk Ratio [RRR] = 1.354, 95% CI: [1.145, 1.563]) and multiracial (RRR = 1.594, 95% CI: [1.173, 2.016]) participants who were exposed to positive tobacco messages from social sources were significantly more likely to report tobacco product use at one-year follow-up than those who were not exposed to social messages. Exposure to positive tobacco messages from environmental sources were not significantly associated with tobacco use one year later. Conclusions: Social messages may play an important role in increasing risk of tobacco use among some minoritized populations. Cultural as well as systemic factors could be addressed in future tobacco prevention programs to decrease the potency of positive tobacco-related social messages among Latino/a/x and multiracial communities.

Predictors of Cessation Outcomes Among Older Adult Smokers Enrolled in a Proactive Tobacco Quitline Intervention

OBJECTIVES

To identify predictors of older adults' likelihood of quitting following engagement in a proactive tobacco quit line.

METHODS

Older (>60 years) participants (N = 186) enrolled in a four-session quit line with 8-weeks of nicotine replacement therapy reported demographics, beliefs, and information about tobacco use. Point prevalence abstinence was reported at 3 and 12-months.

RESULTS

In final models, endorsement of quitting to take control of one's life and confidence in quitting were positively associated with 3-month cessation (OR = 1.74, 95% CI = 1.16, 2.62; OR = 1.75, 95% CI = 1.21, 2.52, respectively). At 12 months, stronger endorsement of quitting to take control of one's life and decreased nicotine dependence were associated with higher cessation (OR = 1.51, 95% CI = 1.05, 2.17; OR = 0.84, 95% CI = 0.71,0.99, respectively).

DISCUSSION

For tobacco cessation among older adults, programs should provide additional support to those with higher nicotine dependence, promote quitting self-efficacy, and encourage quitting as means to gain control of life and health.

Using the Socio-ecological Model to Explore Facilitators and Deterrents of Tobacco Use Among Airmen in Technical Training

INTRODUCTION

Military personnel have some of the highest rates of tobacco use in the USA. Within the Air Force, a common point of Airmen's (re-)initiation of tobacco use is during technical training once the tobacco ban has been lifted. Unfortunately, little is known about what factors facilitate and deter tobacco use during technical training. The socio-ecological model, which emphasizes multiple levels of influence on behavior (e.g., personal, intrapersonal, and environmental), provides a strong and comprehensive basis for which to explore factors that may impact tobacco use during technical training.

MATERIALS AND METHODS

Twenty-two focus groups were conducted among Airmen (n = 10), Military Training Leaders (MTLs, n = 7), and Technical Training Instructors (TTIs, n = 5). Semi-structured focus group protocols were developed based on the socio-ecological model and included questions intended to elicit factors that facilitated and deterred tobacco use during technical training. Focus groups were transcribed and then coded using a hybrid deductive-inductive process.

RESULTS

At the personal level, five factors were identified that influenced tobacco use: choice, fit with lifestyle, associations with the tobacco experience, association with military job outcomes, and association with health outcomes. Three interpersonal level factors were identified: peer influence, leadership influence, and normative beliefs. There were two influential environmental level factors: pricing and promotion and access to tobacco. Except for normative beliefs, all personal, interpersonal, and environmental-level factors were discussed as having aspects that could either facilitate or deter tobacco use. Normative beliefs, an interpersonal-level factor, were only discussed as a facilitator of tobacco use.

CONCLUSIONS

Taken together, study findings can be used to enhance the effectiveness of tobacco prevention and cessation programs for Air Force Technical Trainees. Specific strategies to support the reduction of tobacco use among Airmen are presented.

“It Depends on Where You Are and What Job You Do”: Differences in Tobacco Use across Career Fields in the United States Air Force

While tobacco use within the military is often discussed as being homogenously part of U.S. military culture, literature from civilian populations highlights that tobacco use varies by career field (e.g., “white collar” vs. “blue collar”). The objective of this qualitative study was to compare tobacco use by career fields in the U.S. Air Force. Airmen, Military Training Instructors, and Technical Training Instructors participated in 22 focus groups across five major Air Force Technical Training bases. Focus groups were conducted in-person using semi-structured interview guides and were audio-recorded. A conventional content-coding approach was used to code transcripts. Participants described substantial variation across the careers, which was attributed to social norms and the nature of jobs. Individuals in careers that spend most of their time outside were more likely to permit tobacco use. Conversely, tobacco use was seen as stigmatized in medical fields. Additionally, smokeless tobacco was identified as popular in certain careers because it could be used covertly on the job. Findings suggest that a one-size-fits-all approach to reducing tobacco use through policies and programs may not reflect the realities of military tobacco use. These findings may provide insights into other branches of the U.S. military with similar career fields.

Young Adults May Be Engaging in Risky Behaviors with their E-Cigarettes

E-cigarette use has significantly escalated among young adults in recent years. The purpose of the current study was to better understand alternative ways in which young adults use their e-cigarettes in situations where ad-lib use is prohibited. The current study is a secondary analysis to a parent study assessing facilitators and barriers for tobacco use among young adult military personnel. Ten focus groups were conducted with 83 Airmen at the end of their Technical (advanced) Training. Focus group discussions were transcribed and thematic analysis was used to determine trends related to risky e-cigarette use. Participants described using liquids with extremely high nicotine contents or using the e-cigarette so quickly and intensely that they could not stand up or became ill. Results highlight the ease by which individuals can make alterations to their e-cigarettes or their use behaviors, which could potentially increase their risk of nicotine poisoning.

Cheaper tobacco product prices at US Air Force Bases compared with surrounding community areas, 2019

INTRODUCTION

In March 2017, the US Department of Defense (DoD) implemented a policy requiring all military stores to set tobacco prices equal to 'prevailing prices' in the 'local community' adjusted for state and local taxes. We compared tobacco product prices in a sample of retailers located on five Air Force Bases (AFBs) in Texas and Mississippi with those sold in nearby off-base stores.

METHODS

We constructed a list of on-base and off-base tobacco retailers. Off-base retailers included stores that were located within a 1.5-mile road network service area from main AFB gates. Between July and September 2019, a trained auditor visited 23 on-base and 50 off-base retailers to confirm tobacco product sales, and documented the price of cigarettes and Copenhagen smokeless tobacco. For each area, the median price for each product, as well as the difference in median prices by on-base versus off-base status, was calculated.

RESULTS

The median price of cigarettes and smokeless products was cheaper at on-base retailers. All products were cheaper at on-base stores in Fort Sam Houston and Lackland AFB. Similarly, all products were cheaper in on-base stores at Keesler AFB, with the exception of Marlboro Red packs ($0.22 more), and at Sheppard AFB with the exception of cheapest cigarette cartons ($6.26 more).

CONCLUSION

Despite the implementation of the new DoD policy, tobacco products are cheaper in on-base retailers compared with off-base retailers. Refining of the definitions used and improved compliance with the new DoD policy are needed.

Efficacy of a group-based brief tobacco intervention among young adults aged 18-20 years in the US Air Force

INTRODUCTION

Most smokers begin using tobacco before the age of 25 years, making it important to reduce tobacco use during adolescence and early adulthood. Rates of use are historically higher among military personnel. While 'Tobacco 21' made it illegal for US retailers to sell tobacco to those aged <21 years, the policy did not address cessation for current youth and young adult tobacco users. Additionally, there is limited research on cessation interventions among young adults under 21 years. The current study evaluated the efficacy of a group-based Brief Tobacco Intervention (BTI) among US Air Force trainees, who are predominantly aged 18-20 years and directly impacted by Tobacco 21 legislation.

METHODS

Participants were 2969 US Air Force Trainees from April 2017 through January 2018 cluster randomized to three conditions: 1) BTI + Airman's Guide to Remaining Tobacco Free (AG), 2) AG alone, and 3) the National Cancer Institute's Clearing the Air (CTA) pamphlet. To assess the efficacy of the interventions among people aged 18-20 years, a domain analysis (<21 years, n=2117; and ≥21 years, n=852) of a multinomial logistic regression model was run.

RESULTS

Mono tobacco users aged <21 years at baseline who received the BTI+AG had higher odds of quitting tobacco at 3 months (OR=2.13; 95% CI: 1.02-4.46). Dual and poly users aged <21 years at baseline who received the BTI+AG intervention had higher odds of reducing the number of tobacco products used at 3 months (OR=2.94; 95% CI: 1.03-8.37).

CONCLUSIONS

The BTI was effective for people aged 18-20 years. The current study offers insight into components of interventions that might be successful in helping this age group decrease tobacco use.

Dual and polytobacco use after a period of enforced tobacco cessation

The current study aimed to assess single product, dual, and polytobacco use in a young adult military population and how an enforced tobacco ban during training impacts these behaviors. Participants were 810 U.S. Airmen who reported tobacco use as civilians. Participants completed baseline and one-year follow-up surveys about their tobacco use from 2016 to 2019. Each product used by a participant was assigned a score based on their frequency of use, which were summed to create a total score. Change scores were calculated by determining the difference between baseline and follow-up frequency scores. Tobacco frequency score and the categorical change (e.g., increased, decreased) were compared between groups using t-tests and Chi-squared tests, respectively, adjusting for clustering effects by squadron and base. Among single product users, 44.58% quit using tobacco products, 47.1% remained single product users, and 8.32% became dual or polytobacco users. Among dual users, 39.1% quit, 43.1% became single product users, 14.2% remained dual users, and 3.7% became polytobacco users. Among polytobacco users, 29.9% quit, 43.4% became single product users, 17.9% became dual users, and 8.8% continued poly-tobacco use. Most participants reduced the number and frequency of tobacco products used. Implementing stringent policies that further restrict tobacco use may decrease tobacco product use or frequency of use.

"Nobody Views It As a Negative Thing to Smoke": A Qualitative Study of the Relationship Between United States Air Force Culture and Tobacco Use

INTRODUCTION

Tobacco use has long been a part of military culture, and rates of tobacco use remain higher among military personnel compared to civilians. The current study examines aspects of Air Force tobacco culture that encourage tobacco use.

MATERIALS AND METHODS

We conducted 7 focus groups among Air Force Military Training Leaders (n=48) and 5 focus groups among Technical Training Instructors (n=33) from July 2018 to February 2019.

RESULTS

Tobacco use was seen as a core part of Air Force culture and a low risk behavior, in contrast to other potential activities. Three themes of Air Force culture that facilitate tobacco use emerged: 1) opportunity for work breaks; 2) finding common ground; and 3) stress management or stress relief during deployment. Smoke pits were seen as serving several functions that were not perceived to occur anywhere else: an opportunity for informal communication with leadership, a source of valuable information, and a space for problem solving.

CONCLUSIONS

Airmen viewed tobacco as serving a functional role, which outweighed its harm. Future programs might try to address the functions fulfilled by tobacco in order to enhance their impact.

Use of Tobacco for Weight Control across Products among Young Adults in the U.S. Military

BACKGROUND

Approximately 17% of young adults currently use tobacco, most commonly cigarettes and/or electronic cigarettes (e-cigarettes), followed by other products (i.e., cigarillos, pipe/hookah, smokeless tobacco). Cigarettes have been historically used to control weight. Little is known about use of non-cigarette products for weight control, particularly among non-college young adults. Tobacco use in the military is higher than civilians, and personnel have increased motivation for weight control due to military fitness standards. This population might be vulnerable to use tobacco for this purpose. Purpose: Exploring prevalence, as well as demographic and behavioral correlates, of using tobacco products for weight control, among a large, diverse sample of military young adults. Methods: U.S. Air Force recruits (N = 24,543) completed a questionnaire about tobacco use. Among users of tobacco products, recruits reported if they had ever used that product to maintain their weight. Results: Smokeless tobacco was most commonly used for weight control (12.2%), followed by cigarettes (7.3%), e-cigarettes (5.5%), cigarillos (3.3%), and hookah/pipe (3.2%). Using tobacco for weight control was associated with fewer harm beliefs and more regular use of that product. Among e-cigarette users, having a higher BMI and a lower educational background was associated with ever using this product for weight control. Conclusions: The belief that a tobacco product helps control one's weight might increase the prevalence, and frequency of use, of that product among military young adults. Tobacco cessation programs should assess for this motivation of use and provide education about tobacco harm and alternative strategies for weight maintenance.
