Insomnia and motor vehicle accident-related injuries, Active Component, U.S. Armed Forces, 2007 – 2016

Infographic
1/25/2018
Insomnia is the most common sleep disorder in adults and its incidence in the U.S. Armed Forces is increasing. A potential consequence of inadequate sleep is increased risk of motor vehicle accidents (MVAs). MVAs are the leading cause of peacetime deaths and a major cause of non-fatal injuries in the U.S. military members. To examine the relationship between insomnia and motor vehicle accident-related injuries (MVAs) in the U.S. military, this retrospective cohort study compared 2007 – 2016 incidence rates of MVA-related injuries between service members with diagnosed insomnia and service members without a diagnosis of insomnia. After adjustment for multiple covariates, during 2007 – 2016, active component service members with insomnia had more than double the rate of MVA-related injuries, compared to service members without insomnia. Findings:  •	Line graph shows the annual rates of motor vehicle accident-related injuries, active component service members with and without diagnoses of insomnia, U.S. Armed Forces, 2007 – 2016  •	Annual rates of MVA-related injuries were highest in the insomnia cohort in 2007 and 2008, and lowest in 2016 •	There were 5,587 cases of MVA-related injuries in the two cohorts during the surveillance period. •	Pie chart displays the following data: 1,738 (31.1%) in the unexposed cohort and 3,849 (68.9%) in the insomnia cohort The highest overall crude rates of MVA-related injuries were seen in service members who were: •	Less than 25 years old •	Junior enlisted rank/grade •	Armor/transport occupation •	 •	With a history of mental health diagnosis •	With a history of alcohol-related disorders Access the full report in the December 2017 (Vol. 24, No. 12).

Seizures among Active Component service members, U.S. Armed Forces, 2007 – 2016

Infographic
1/25/2018
This retrospective study estimated the rates of seizures diagnosed among deployed and non-deployed service members to identify factors associated with seizures and determine if seizure rates differed in deployment settings. It also attempted to evaluate the associations between seizures, traumatic brain injury (TBI), and post-traumatic stress disorder (PTSD) by assessing correlations between the incidence rates of seizures and prior diagnoses of TBI and PTSD. Seizures have been defined as paroxysmal neurologic episodes caused by abnormal neuronal activity in the brain. Approximately one in 10 individuals will experience a seizure in their lifetime. Line graph 1: Annual crude incidence rates of seizures among non-deployed service members, active component, U.S. Armed Forces data •	A total of 16,257 seizure events of all types were identified among non-deployed service members during the 10-year surveillance period. •	The overall incidence rate was 12.9 seizures per 10,000 person-years (p-yrs.) •	There was a decrease in the rate of seizures diagnosed in the active component of the military during the 10-year period. Rates reached their lowest point in 2015 – 9.0 seizures per 10,000 p-yrs. •	Annual rates were markedly higher among service members with recent PTSD and TBI diagnoses, and among those with prior seizure diagnoses. Line graph 2: Annual crude incidence rates of seizures by traumatic brain injury (TBI) and recent post-traumatic stress disorder (PTSD) diagnosis among non-deployed active component service members, U.S. Armed Forces •	For service members who had received both TBI and PTSD diagnoses, seizure rates among the deployed and the non-deployed were two and three times the rates among those with only one of those diagnoses, respectively. •	Rates of seizures tended to be higher among service members who were: in the Army or Marine Corps, Female, African American, Younger than age 30, Veterans of no more than one previous deployment, and in the occupations of combat arms, armor, or healthcare Line graph 3: Annual crude incidence rates of seizures diagnosed among service members deployed to Operation Enduring Freedom, Operation Iraqi Freedom, or Operation New Dawn, U.S. Armed Forces, 2008 – 2016  •	A total of 814 cases of seizures were identified during deployment to operations in Iraq and Afghanistan during the 9-year surveillance period (2008 – 2016). •	For deployed service members, the overall incidence rate was 9.1 seizures per 10,000 p-yrs. •	Having either a TBI or recent PTSD diagnosis alone was associated with a 3-to 4-fold increase in the rate of seizures. •	Only 19 cases of seizures were diagnosed among deployed individuals with a recent PTSD diagnosis during the 9-year surveillance period. •	Overall incidence rates among deployed service members were highest for those in the Army, females, those younger than age 25, junior enlisted, and in healthcare occupations.

Contraception among active component service women, U.S. Armed Forces, 2012 – 2016

Infographic
1/5/2018
Because the majority of women serving in the Armed Forces are of childbearing age, and women’s military career opportunities have expanded into combat roles, contraceptive health care is an increasingly important public health issue. The lack of available, population-based descriptive information on contraceptive use among U.S. service women has generated questions and concerns about ready access to these medical products. This infographic summarizes the annual prevalence of permanent sterilization, as well as use of long – and short-acting reversible contraceptives (LARCs and SARCs, respectively), contraceptive counseling services, and use of emergency contraception from 2012 through 2016, among active component service women. FINDINGS •	2012 through 2016, Sterilization decreased from 4.2% to 3.6% LARC use increased from 17.2% to 21.7%; SARC use decreased from 38.5% to 30.4%. •	Emergency contraception use increased from 0.4% to 1.9%. •	Among deployed women, the average annual prevalence of permanent sterilization was 4.2%. •	For deployed women, LARC use was 17.9% SARC use was 28.0%. •	Emergency contraception use among deployed women was 0.4%. •	262,907 (76.2%) women of childbearing potential (WOCBP) used either a LARC or a SARC at some time during the surveillance period. •	The vast majority of service women have utilized at least one form of contraception, and women are selecting LARCs in greater numbers with each passing year.

Measles, Mumps, Rubella, and Varicella: Among service members and other beneficiaries of the Military Health System, 2010 – 2016

Infographic
11/3/2017
Measles, mumps, rubella, and varicella (MMR/V) are highly communicable infectious diseases whose causative agents are spread through contact with contaminated surfaces or airborne droplets. MMR/V were common in the U.S. before the introduction of licensed vaccines: measles (1963), mumps (1967), rubella (1969), and varicella (1995). Since then, these vaccines have been important components of routine pediatric preventive care. This report highlights the recent trends in MMR/V in both military and civilian populations as well as the importance of primary and booster vaccinations.  During 2010 – 2016, there were: •	11 confirmed measles cases – one was in a service member. •	76 confirmed mumps cases – 28 were in service members. •	7 confirmed rubella cases – two were in service members. •	62 confirmed varicella cases among service members. The reporting of cases of varicella in non-military personnel was not mandated until 2017. Individuals at highest risk for MMR/V •	Infants •	Unvaccinated persons •	Inadequately vaccinated persons •	Individuals living in communities with low vaccination rates •	Persons living in crowded and unsanitary conditions •	Those with compromised immune systems Access the full report in MSMR Vol. 24 No. 10 October 2017 for more information at Health.mil/MSMR A picture of service members in communal area displays as well as an image of team work activities.
