BACKGROUND The specific underlying causes of adult weight gain remain uncertain. OBJECTIVE The objective was to determine the association of 3 measures of eating behavior with weight gain and body mass index (BMI; in kg/m(2)) in adults. DESIGN Current dietary restraint, disinhibition, and hunger were assessed with the use of the Eating Inventory in 638(More)
BACKGROUND Military exercises generate high levels of stress to simulate combat, providing a unique opportunity to examine cognitive and physiologic responses of normal humans to acute stress. METHODS Cognitive and physiologic markers of stress were evaluated before, during, and after an intense training exercise conducted for 53 hours in the heat.(More)
BACKGROUND Factors affecting the accuracy of reported energy intake (rEI) need to be identified. OBJECTIVE Our objective was to investigate the association of psychological measures of eating behavior with the accuracy of rEI assessed by 7-d weighed intakes, a 24-h recall, and a food-frequency questionnaire. DESIGN Subjects were 26 restrained eaters(More)
INTRODUCTION Anecdotal reports from military conflicts suggest cognitive performance and mood are severely degraded by the stress of combat. However, little objective information is available to confirm these observations. METHODS Our laboratory had several unique opportunities to study cognitive function in warfighters engaged in exercises designed to(More)
BACKGROUND Recent studies have questioned the accuracy of using the current recommended dietary allowances (RDAs) to predict usual energy requirements in adults. OBJECTIVE We developed equations to predict adult energy requirements from simple anthropometric and laboratory measures by using the doubly labeled water method to determine each subject's total(More)
PURPOSE Determine the short-term effects of creatine supplementation on performance of military tasks, thermoregulation, and health risks. METHODS Male military personnel were randomly assigned to a creatine (CR; N = 8) or a placebo (CON; N = 8) supplementation group. Testing was conducted at baseline, after a 6-day load phase (20 g/d), and after 4 weeks(More)
In the United States, nationally representative civilian studies have shown that BMI is associated with select sociodemographic characteristics. Active-duty military personnel are not included in these surveys and the persistence of these associations in military personnel is unknown. Data from the worldwide, representative 2002 and 2005 Department of(More)
New approaches to assess energy intake (EI) may have advantages over traditional written methods, but validity of these emerging methodologies must be demonstrated. This exploratory study compared EI obtained using a hand-held personal digital assistant (PDA) and traditional written records with total energy expenditure measured by doubly labeled water(More)
BACKGROUND The association of psychological eating behavior constructs with overweight and obesity during early adult life and middle age has been documented in several studies. However, the association of eating behavior with unexplained weight change in old age is relatively unexplored. METHODS Body weight, eating behavior (dietary restraint,(More)
OBJECTIVE To comply with Army Regulation 600-9, The Army Weight Control Program (AWCP), soldiers must meet age-adjusted body fat standards, regardless of whether they meet or exceed weight-for-height allowances. Recent revisions to Department of Defense (DoD) policies require changes to the AWCP. Specifically, we assessed the effects of increasing(More)
