Weight gain as a barrier to smoking cessation among military personnel.

PURPOSE: To assess the relationships between active-duty military status, military weight standards, concern about weight gain, and anticipated relapse after smoking cessation. DESIGN: Cross-sectional study. SETTING: Hospital-based tobacco cessation program. SUBJECTS: Two hundred fifty-two enrollees, of 253 eligible, to a tobacco cessation program in 1999 (135 men, 117 women; 43% on active duty in the military). MEASURES: Independent variables included gender, body mass index (weight/height2), and military status. Dependent variables included about weight gain with smoking cessation and anticipated relapse. RESULTS: In multivariate regression analyses that controlled for gender and body mass index, active-duty military status was associated with an elevated level of concern about weight gain (1.9-point increase on a 10-point scale; 95% confidence interval [CI], 1.0- to 2.8-point increase), as well as higher anticipated relapse (odds ratio [OR] = 3.6; 95% CI, 1.3 to 9.8). Among subjects who were close to or over the U.S. Air Force maximum allowable weight for height, the analogous OR for active-duty military status was 6.9 (p = .02). CONCLUSIONS: Occupational weight standards or expectations may pose additional barriers for individuals contemplating or attempting smoking cessation, as they do among active-duty military personnel. These barriers are likely to hinder efforts to decrease smoking prevalence in certain groups.

Predictors of low physical fitness in a cohort of active-duty U.S. Air Force members.

BACKGROUND: Each branch of the U.S. armed forces has standards for physical fitness as well as programs for ensuring compliance with these standards. In the U.S. Air Force (USAF), physical fitness is assessed using submaximal cycle ergometry to estimate maximal oxygen uptake (VO2(max)). The purpose of this study was to identify the independent effects of demographic and behavioral factors on risk of failure to meet USAF fitness standards (hereafter called low fitness). METHODS: A retrospective cohort study (N=38,837) was conducted using self-reported health risk assessment data and cycle ergometry data from active-duty Air Force (ADAF) members. Poisson regression techniques were used to estimate the associations between the factors studied and low fitness. RESULTS: The factors studied had different effects depending on whether members passed or failed fitness testing in the previous year. All predictors had weaker effects among those with previous failure. Among those with a previous pass, demographic groups at increased risk were toward the upper end of the ADAF age distribution, senior enlisted men, and blacks. Overweight/obesity was the behavioral factor with the largest effect among men, with aerobic exercise frequency ranked second; among women, the order of these two factors was reversed. Cigarette smoking only had an adverse effect among men. For a hypothetical ADAF man who was sedentary, obese, and smoked, the results suggested that aggressive behavioral risk factor modification would produce a 77% relative decrease in risk of low fitness. CONCLUSIONS: Among ADAF members, both demographic and behavioral factors play important roles in physical fitness. Behavioral risk factors are prevalent and potentially modifiable. These data suggest that, depending on a member's risk factor profile, behavioral risk factor modification may produce impressive reductions in risk of low fitness among ADAF personnel.

Short term effects of cigarette smoking on hospitalisation and associated lost workdays in a young healthy population.

OBJECTIVE: There are relatively few published studies conducted among people of younger ages examining short term outcomes of cigarette smoking, and only a small number with outcomes important to employers. The present study was designed to assess the short term effects of smoking on hospitalisation and lost workdays. DESIGN: Retrospective cohort study. SETTING: Military population. SUBJECTS: 87 991 men and women serving on active duty in the US Army during 1987 to 1998 who took a health risk appraisal two or more times and were followed for an average of 2.4 years. MAIN OUTCOME MEASURES: Rate ratios for hospitalisations and lost workdays, and fraction of hospitalisations and lost workdays attributable to current smoking (population attributable fraction). RESULTS: Compared with never smokers, men and women who were current smokers had higher short term rates of hospitalisation and lost workdays for a broad range of conditions. Population attributable fractions (PAFs) for outcomes not related to injury or pregnancy were 7.5% (men) and 5.0% (women) for hospitalisation, and 14.1% (men) and 3.0% (women) for lost workdays. Evidence suggests that current smoking may have been under reported in this cohort, in which case the true PAFs would be higher than those reported. CONCLUSIONS: In this young healthy population, substantial fractions of hospitalisations and lost workdays were attributable to current smoking, particularly among men.

Survey of USAF flight surgeons regarding clinical preventive services, using CHD as an indicator.

BACKGROUND: A recent Department of Defense study revealed that nonpharmacologic therapy is not well documented in medical records of individuals identified at risk for coronary heart disease (CHD). Exercise and weight control are often underemphasized relative to dietary and medication interventions, even in medical journal review articles on management of dyslipidemia. METHODS: A literature review of interventions consisting of exercise alone or with diet is presented. A brief survey was developed to assess the knowledge and beliefs of USAF flight surgeons regarding training received for, and delivery of, clinical preventive services. In addition, the respondents were given a scenario patient with high cholesterol to manage. RESULTS AND DISCUSSION: The literature review demonstrates the beneficial effect of exercise alone or with dietary interventions on reducing total cholesterol and increasing high-density lipoprotein (HDL). The survey reveals that USAF flight surgeons believe that more preventive medicine training is needed in the USAF flight surgeon course, graduate medical education, and medical school. Given a scenario patient with hypercholesterolemia, the flight surgeons believe that nonpharmacologic therapy with consults to the base Health and Wellness Center (HAWC), along with follow-up by the physician, is appropriate initial medical treatment rather than pharmacologic therapy. CONCLUSIONS: The primary treatment for prevention of CHD should be an organized exercise and diet program. This treatment is proven effective through clinical trials and is supported by the flight surgeon survey results. Additional benefits of an organized exercise and diet program include decreased obesity with its associated complications, decreased incidence of hypertension, decreased cancer risk, and decreased risk for diabetes mellitus.
