The results are in: 2011 Health Related Behaviors Survey

The results from the 2011 DoD Health Related Behaviors Survey show that active duty service members excel in many areas with regard to their health, but there is still room for improvement.

The purpose of the 2011 Department of Defense Health Related Behaviors Survey of Active Duty Military Personnel (HRB) is to assess the health practices of active-duty service members. Substance abuse, mental and physical health, and lifestyle choices are important matters, especially when you need to be at your best for the demands of military life. Certain areas of this study directly affect human performance, and results (as reported in the Executive Summary) show that health behaviors vary between services.

Physical Activity/Body composition

Here are some figures from the Physical Activity/Body Composition portion:

  • Overall, service members have lower rates of obesity (as defined by BMI) compared to the general public.
  • More than one-third of active-duty service members age 20 and older were considered to be at a healthy weight, which exceeds the Healthy People goal as well as civilian population estimates.
  • 75% of active-duty members practiced moderate to vigorous physical activity in the 30 days prior to the survey, with Army and Navy personnel having the highest rates.
  • Almost half of service members do strength training three or more days a week.

Physical health and fitness are key components to optimal fitness. While these numbers are encouraging, there is no doubt that a larger portion of the military should be at a healthy weight and fit enough to fight. Make fitness and weight management your priority for performance.

Sleep

  • Only 40% of all active-duty personnel surveyed get the recommended seven to eight hours of sleep per night.

Sleep is an important factor in recovery. Poor sleep habits can take a physical and mental toll on your health, your relationships, and your performance.

Tobacco and alcohol

One area where the military could improve is in the use of tobacco products and alcohol:

  • Almost one-quarter of service members reported smoking a cigarette in the 30 days prior to taking the survey, which is higher than the civilian population and the Healthy People objective.
  • Smokeless tobacco use is also prevalent in the military with 12.8% of all service members using smokeless tobacco in the month leading up to the survey.
  • Rates of binge drinking were higher in the military than in the civilian population and more prevalent in the Marine Corps than in any other branch.

Tobacco in any form is detrimental to your health. If you’re thinking about quitting smoking or would like to talk to someone about your alcohol use, there are lots of resources and professionals that can help you achieve your goal.

Stress and mental health

After more than a decade of ongoing war, troops have—and will continue to experience—significant mental stress as a result of their service. In general, 5-20% of service members reported high rates of anxiety, depression, PTSD, and/or other mental health concerns.

  • The most common military-related sources of stress were being away from family and friends and changes in workload but included financial problems and family members’ health problems.
  • Women reported experiencing personal sources of stress more often than men did.
  • Those who drank heavily were more likely to report problems with money and relationships.

Drinking, smoking, overeating, and even attempted suicide are all negative coping factors when dealing with stress. The survey found that the most effective methods of coping were planning to solve problems and talking with friends or family members. Find out how to use productive and effective methods for coping with stress and mental health.

Nutrition and dietary supplements

Being fueled to fight is an important component for anyone in the military. Proper nutrition requires consuming healthy—and avoiding bad and potentially harmful—foods and beverages.

  • According to the survey, active-duty personnel eat too many unhealthy foods such as snacks, sweets, and sugary drinks and not enough of the recommended servings of fruits and vegetables.
  • More than one-third of personnel reported daily dietary supplement use.

What you decide to put in your body now may affect your performance and your career later. For more information on nutrition for combat effectiveness, read Chapter 15 of the Warfighter Nutrition Guide. And make sure you know what you’re putting into your body. Dietary supplements are not subject to pre-market approval by the FDA, and there are many ingredients that may do more harm than help.

DMAA products’ downward spiral

HPRC’s updated list of DMAA-containing products shows the impact of FDA’s announcement in April that dietary supplements containing DMAA are illegal.

Since we first posted our list of DMAA-containing dietary supplement products in December 2011, and especially since FDA’s announcement in April 2013, the number of products being manufactured with this ingredient has continued to decline. Our search does still occasionally turn up products with DMAA that were not on our previous lists: just six new products have been added since our last update in April 2013. Despite these additions, this update shows that about 80 dietary supplement products are apparently still being manufactured with DMAA, but note that many are by non-U.S. sources. Over the lifetime of this list 125 products have been discontinued or reformulated to exclude DMAA, including some of the most well-known ones. To the best of our knowledge and searching, 68 of these no longer appear for sale, even from distributor stock. You'll find our updated list of products containing DMAA here.

FDA warns: DMAA in dietary supplements now illegal

FDA urges consumers to check all dietary supplement product labels to ensure they do not contain the illegal stimulant DMAA.

The Food and Drug Administration (FDA) has issued a Consumer Update warning of the potential dangers of DMAA, which was announced illegal in dietary supplements on 11 April 2013. DMAA is also referred to as dimethylamylamine and other names. This dietary supplement product ingredient has been used in many weight-loss, bodybuilding, and performance-enhancement products. FDA received numerous reports of illnesses and death from the use of products containing DMAA; commonly reported reactions include heart and nervous system problems as well as psychiatric disorders. DMAA has been the focus of conflicting information regarding whether or not it is a natural extract from geranium. FDA has now found “the information insufficient to defend the use of DMAA as an ingredient in dietary supplements.” Online, FDA also stated, "Dietary supplements containing DMAA are illegal and FDA is doing everything within its authority to remove these products from the market."

DMAA products continue to dwindle

HPRC has updated its list of DMAA-containing products, showing that 20 more products have been discontinued or reformulated to exclude the ingredient.

Since we first posted our list of DMAA-containing dietary supplement products in December 2011, the number of products being manufactured with this ingredient has continued to decline. Our most recent update shows only 79 dietary supplement products still being manufactured with DMAA; over the past 13 months more than 110 products have been discontinued or reformulated to exclude DMAA. Our search does still occasionally turn up products with DMAA that were not on our previous lists, but this is increasingly rare, with only four additions since our last update in October 2012.

Caffeine in supplements – how much?

Some of the most popular dietary supplements sold on military bases may give inaccurate—or no—information about caffeine content on their labels.

A Military Times article reports on a recent study of more than 30 of the most popular dietary supplements (in capsule form) sold on military bases analyzed to determine their caffeine content. Of the 20 supplements that listed caffeine as an ingredient on their labels, six did not specify the amount. These same six contained high amounts of caffeine (210-310 mg per serving)—three or more times the amount permitted by law in soft drinks. Five others revealed significantly different amounts—some more, some less—than the quantity stated on the product label.

Consuming too much caffeine can result in health issues. And if you don’t know how much is in the supplement you’re taking, it could be easy to overdo it if you also drink coffee or energy drinks. Visit the Operation Supplement Safety (OPSS) FAQ on caffeine for additional information.
