The metabolic responses to a complete 74 hour fast (CF) and to a more prolonged 21 day period of hypocaloric intake (HC) were investigated in healthy military-eligible women and comparisons mad with those in healthy military-eligible men. The CF study included a study of leucine flux, glucose production, glycerol and free fatty acid appearance rates. The pattern of change in substrate utilization revealed the expected shift toward oxidation of body fat. The changes were similar in men and women. The RC (30% reduction from a eucaloric level) study also included 24h substrate kinetics, with a 90 min exercise period (55% VO2 max). Again, the kinetic metabolic response was consistent with a sub-optimal energy intake. There were no distinct differences between the metabolic response in woman and men. Tests of physical performance did not reveal differences between genders, Mental performance data are being evaluated. Hence, under highly controlled experimental conditions men and women respond similarly to an acute total fast and to a sub-optimal energy intake.

Two major series of investigations are being undertaken to explore the metabolic responses of women who meet military standards for body-weight and percent body-fat to the nutritional stressors of food restriction. A comparison of their responses is being made with those occurring in men, who also meet the standards established by the military. The first series (Series 1) has been devoted to the temporal (progressive) changes in lipid, carbohydrate and protein metabolism that occur during a short-term (3 day) fasting period. Data obtained so far for leucine kinetics, nitrogen output, and fatty acid kinetics do not reveal any significant differences, either qualitatively or quantitatively in the metabolic response to an acute total food lack in women versus men. This series of studies will be completed pending further analysis of samples obtained. Work is now underway on the second set of studies. The first phase of this 3-week hypercaloric intake/metabolic study involves the participation of both women and men who receive a hypocaloric diet for 21 days to achieve a 900 Kcal daily dietary deficit that is based on an equal restriction of both lipid and carbohydrate but with keeping protein content at a relatively generous intake of 1.2 g/kg/day. Body composition, metabolic and physical and mental performance changes are being monitored to assess whether there are gender differences to partial and more prolonged energy restriction.

Few human activities demand or deserve as much attention of the citizens of a nation as the array of man-made and natural “environmental” threats faced by the soldiers and other warriors defending the nation – those that pose the risk of disease, injury, combat wounds, and even death. This book is the Army’s first detailing research in computational physiology models and highlighting pivotal research. It outlines the extent to which basic and applied biomedical scientists, clinicians, modelers, and others strive to understand the extent of these threats, and provide intellectual and materiel options to mitigate these risks. This book summarizes major Army research efforts to quantify and model military relevant physiology. These chapters highlight the translation of this research into useful predictive tools. The tools are of importance to medical planners, materiel developers, commanders, and in many cases, every soldier. These chapters detail the experimental basis for many of the predictive tools that are currently in use. This book is written for military clinicians, and medical researchers who may be reasonably expected to explain some of the background, as well as those who will extend the research. Many people will find this book interesting because it details research on topics that affect everyone in everyday life, including how we sleep, eat, and exercise, as well as more specific topics such as the effects of caffeine on performance, risks associated with laser pointers, and even Army blast models that have influenced safety thresholds for car airbag deployments.

The primary purpose of fitness and body composition standards in the U.S. Armed Forces has always been to select individuals best suited to the physical demands of military service, based on the assumption that proper body weight and composition supports good health, physical fitness, and appropriate military appearance. The current epidemic of overweight and obesity in the United States affects the military services. The pool of available recruits is reduced because of failure to meet body composition standards for entry into the services and a high percentage of individuals exceeding military weight-for-height standards at the time of entry into the service leave the military before completing their term of enlistment. To aid in developing strategies for prevention and remediation of overweight in military personnel, the U.S. Army Medical Research and Materiel Command requested the Committee on Military Nutrition Research to review the scientific evidence for: factors that influence body weight, optimal components of a weight loss and weight maintenance program, and the role of gender, age, and ethnicity in weight management.

Recognizing the importance of good nutrition for physical and mental status, the Department of Defense asked the Institute of Medicine to guide the design of the nutritional composition of a ration for soldiers on short-term, high-stress missions. Nutrient Composition of Rations for Short-Term, High-Intensity Combat Operations considers military performance, health concerns, food intake, energy expenditure, physical exercise, and food technology issues. The success of military operations depends to a large extent on the physical and mental status of the individuals involved. Appropriate nutrition during assault missions is a continuous challenge mainly due to diminished appetites of individuals under stress. Many less controllable and unpredictable factors, such as individual preferences and climate, come into play to reduce appetite. In fact, soldiers usually consume about half of the calories needed, leaving them in a state called "negative energy balance." The consequences of being in negative energy balance while under these circumstances range from weight loss to fatigue to mental impairments. An individual's physiological and nutritional status can markedly affect one's ability to maximize performance during missions and may compromise effectiveness. With the number of these missions increasing, the optimization of rations has become a high priority.

The U.S. military has been continuously engaged in foreign conflicts for over two decades. The strains that these deployments, the associated increases in operational tempo, and the general challenges of military life affect not only service members but also the people who depend on them and who support them as they support the nation â€" their families. Family members provide support to service members while they serve or when they have difficulties; family problems can interfere with the ability of service members to deploy or remain in theater; and family members are central influences on whether members continue to serve. In addition, rising family diversity and complexity will likely increase the difficulty of creating military policies, programs and practices that adequately support families in the performance of military duties. Strengthening the Military Family Readiness System for a Changing American Society examines the challenges and opportunities facing military families and what is known about effective strategies for supporting and protecting military children and families, as well as lessons to be learned from these experiences. This report offers recommendations regarding what is needed to strengthen the support system for military families.

In the United States, some populations suffer from far greater disparities in health than others. Those disparities are caused not only by fundamental differences in health status across segments of the population, but also because of inequities in factors that impact health status, so-called determinants of health. Only part of an individual's health status depends on his or her behavior and choice; community-wide problems like poverty, unemployment, poor education, inadequate housing, poor public transportation, interpersonal violence, and decaying neighborhoods also contribute to health inequities, as well as the historic and ongoing interplay of structures, policies, and norms that shape lives. When these factors are not optimal in a community, it does not mean they are intractable: such inequities can be mitigated by social policies that can shape health in powerful ways. Communities in Action: Pathways to Health Equity seeks to delineate the causes of and the solutions to health inequities in the United States. This report focuses on what communities can do to promote health equity, what actions are needed by the many and varied stakeholders that are part of communities or support them, as well as the root causes and structural barriers that need to be overcome.
