RESUMO
OBJECTIVES: To examine racial disparities in prenatal care (PNC) utilization and infant small for gestational age (SGA) among active duty US military women, a population with equal access to health care and known socioeconomic status. METHODS: Department of Defense Birth and Infant Health Research program data identified active duty women with singleton live births from January 2003 through August 2015. Administrative claims data were used to define PNC utilization and infant SGA, and log-binomial regression models estimated associations with race/ethnicity. To examine whether associations between maternal race/ethnicity and infant SGA were subject to effect measure modification, respective analyses were stratified by demographic and health characteristics. RESULTS: Overall, 12.2% of non-Hispanic White women initiated PNC after the first trimester, compared with 14.8% of American Indian/Alaska Native, 15.1% of Asian/Pacific Islander, 14.2% of non-Hispanic Black, and 13.0% of Hispanic women. Infant SGA prevalence was 2.4% and 1.6% among non-Hispanic Black and White women, respectively (aRR 1.52, 95% CI 1.40-1.64). This disparity persisted across stratified analyses, particularly among non-Hispanic Black versus White women with a preeclampsia or hypertension diagnosis in pregnancy (RR 1.96, 95% CI 1.67-2.29) and those aged 35 + years at infant birth (RR 2.04, 95% CI 1.56-2.67). CONCLUSIONS FOR PRACTICE: In multiple assessments of PNC utilization and infant SGA, non-Hispanic Black military women had consistently worse outcomes than their non-Hispanic White counterparts. This suggests that equal access to health care does not eliminate racial disparities in outcomes or utilization; additional research is needed to elucidate the underlying etiology of these disparities.

The U.S. military has witnessed rising obesity among active component service members. The Department of Defense authorized coverage of weight loss medications in 2018, but no study has evaluated prescription prevalence within the active component. This descriptive retrospective cohort study analyzed data from active component U.S. military service members from January 2018 through June 2023. The study used data from the Defense Medical Surveillance System to determine prescription period prevalence of weight loss medication. Data on demographics, body mass index, and history of diabetes were considered. The study revealed a 100-fold increase in the prescription period prevalence of weight loss agents in the active component from their initial authorization date. Demographics associated with higher prescription period prevalence were non-Hispanic Black race and ethnicity, female sex, and older age. Service members in the health care occupations and the Navy had higher prevalence compared to other service branches and occupations. The findings indicate a significant rise in the period prevalence of weight loss prescriptions over time. Further research is recommended to assess the effectiveness, safety, and use in austere military environments.

The Department of Veterans Affairs and Department of Defense Clinical Practice Guideline (VA/DOD CPG) provides evidence-based management pathways to mitigate the negative consequences of common sleep disorders among service members (SMs). This retrospective cohort study estimated the incidence of chronic insomnia in active component military members from 2012 through 2021 and the percentage of SMs receiving VA/DOD CPG-recommended insomnia treatments. During this period, 148,441 incident cases of chronic insomnia occurred, with an overall rate of 116.1 per 10,000 person-years (p-yrs). A sub-analysis of SMs with chronic insomnia diagnosed during 2019-2020 found that 53.9% received behavioral therapy and 72.7% received pharmacotherapy. As case ages increased, the proportion who received therapy decreased. Co-existing mental health conditions increased the likelihood of receiving therapy for insomnia cases. Clinician education about the VA/DOD CPG may improve utilization of these evidence-based management pathways for SMs with chronic insomnia.

Post -acute sequalae of COVID-19 (PASC) among U.S. military members remains unexplored. A cohort study of U. S. military members who had a COVID-19 test result, with the specimen collected between March 1, 2020 and November 30, 2021 was conducted. Demographic, inpatient and outpatient data including cardiac event diagnoses were extracted from electronic medical records and compared COVID-19 test-positive and COVID-19 test-negative service members. We used univariate and multivariable logistic regression methods to determine the effect PASC on select cardiac events. Among 997,785 service members, 15,779 (1.6%) were diagnosed with a cardiac event. In fully adjusted models, PASC was significantly associated with increased odds of any cardiac event [OR =1.64 (95% CI: 1.57, 1.71]. PASC was associated with increased odds of myocarditis [OR = 5.86 (95% CI: 4.22, 8.15)], pericarditis [OR =3.08 (95% CI: 2.31, 4.11)], syncope [OR =1.52 (95% CI: 1.41, 1.63)], tachycardia [OR =1.72 (95% CI: 1.56, 1.89)], heart failure [OR =2.15 (95% CI: 1.76, 2.63)], bradycardia [OR =1.71 (95% CI: 1.50, 1.96)], and atrial fibrillation [OR =1.33(95% CI: 1.02, 1.74)] in fully adjusted models. In a sensitivity analysis of military members with no history of cardiac events, PASC was still significantly associated with increased odds of any cardiac event [OR =1.75 (95% CI: 1.67, 1.84)]. In conclusion, we observed a significant association between PASC and cardiac outcomes including; myocarditis, pericarditis, and heart failure. These associations were observed in a relatively young and healthy population and among those without pre-existing cardiac diagnoses.
RESUMO
INTRODUCTION: A booster dose of messenger RNA vaccine protects against severe COVID-19 outcomes. This study examined the incidence of COVID-19 booster vaccination among active-duty U.S. military servicemembers between August 2021 and January 2022, factors associated with vaccination uptake, and trends over time. METHODS: This was a retrospective cohort study of active-duty military personnel using data from the Defense Medical Surveillance System. Participants were included if they served in the active component from August 2021 through January 2022 and were eligible to receive a COVID-19 booster dose by January 2022. Adjusted hazard ratio estimates of time to booster vaccination were calculated using Cox proportional hazards regression. RESULTS: Lower booster vaccine uptake was seen in the U.S. military (25%) than among the general U.S. population at the same time (45%). Booster vaccination increased with older age, with greater education, with higher income, among women, and among those stationed overseas; it decreased with previous COVID-19 infection and use of the Janssen vaccine. There were no significant racial or ethnic disparities in booster vaccination. CONCLUSIONS: In the absence of a compulsory vaccination policy, lower booster vaccine uptake was seen among servicemembers than among the general U.S. population, particularly among members who were younger, were male, Marines, and had a previous history of infection. Low vaccination rates not only increase the risk of acute and long-term health effects from COVID-19 among servicemembers, but they also degrade the overall readiness of the U.S. military.

Importance: No studies to date have evaluated the effectiveness of 3 COVID-19 vaccines in the US military population, especially during the circulation of the SARS-CoV-2 Delta (B.1.617.2) variant. Objective: To estimate the effectiveness of the mRNA-1273, BNT162b2, and JNJ-78436735 vaccines among US military personnel before and during the predominance of the Delta variant in the US. Design, Setting, and Participants: This case-control study was conducted among all unvaccinated and fully vaccinated US military personnel who had a documented SARS-CoV-2 test performed in the US between January 1 and September 24, 2021. Individuals were identified using Department of Defense (DOD) electronic medical, laboratory, and surveillance databases. The pre-Delta period was defined as January 1 to May 31, 2021, and the Delta period as June 19 to September 24, 2021. Case individuals were defined by a positive polymerase chain reaction SARS-CoV-2 test result or a positive antigen test result with symptoms. Control individuals had at least 1 negative SARS-CoV-2 test result. Exposures: COVID-19 vaccination with the mRNA-1273, BNT162b2, or JNJ-78436735 vaccine, assessed from DOD electronic vaccination records. Main Outcomes and Measures: COVID-19 vaccine effectiveness overall, by vaccine type, and by outcome stratified by the pre-Delta and Delta periods in the US. Vaccine effectiveness was estimated as 100 × (1 - odds ratio) in a logistic regression model with adjustment for potential confounders. Results: The cohort included 441â¯379 individuals, with 290â¯256 in the pre-Delta period (236â¯555 [81%] male; median age, 25 years [range, 17-68 years]) and 151â¯123 in the Delta period (120â¯536 [80%] male; median age, 26 years [range, 17-70 years]). Adjusted vaccine effectiveness of all vaccines was significantly higher during the pre-Delta period (89.2%; 95% CI, 88.1%-90.1%) compared with the Delta period (70.2%; 95% CI, 69.3%-71.1%) for all outcomes, an overall decrease of 19%. mRNA-1273 vaccine effectiveness was highest in the pre-Delta (93.5%; 95% CI, 91.9%-94.7%) and Delta (79.4%; 95% CI, 78.3%-80.4%) periods for all outcomes, whereas the JNJ-78436735 vaccine had the lowest effectiveness during the pre-Delta (81.8%; 95% CI, 74.2%- 87.1%) and Delta (38.3%; 95% CI, 34.5%-41.9%) periods. Effectiveness for all vaccines during both periods was higher for symptomatic infection and hospitalization among individuals with SARS-CoV-2 infection. Conclusions and Relevance: In this case-control study, among US military personnel, COVID-19 vaccine effectiveness was significantly lower during the period when the Delta variant predominated compared with the period before Delta variant predominance; this was especially true for the JNJ-78436735 vaccine. These findings were confounded by time since vaccination; this and the change in effectiveness support the need for booster doses and continued evaluation of vaccine effectiveness as new variants of SARS-CoV-2 emerge.

The incidence of human papillomavirus (HPV) related cancers is growing in the United States. Active duty service members (ADSM) have higher rates of HPV infection than civilians and are therefore at greater risk of developing HPV-related cancers. The purpose of this commentary is to examine the burden of HPV-related cancers in ADSM. The current HPV vaccination and cervical cancer screening uptake rates of U.S. ADSM are presented, including a literature review of military-focused studies on HPV vaccination and cervical cancer screenings. We provide directions for future research, interventions, and policy recommendations to improve HPV-related cancer prevention among ADSM.

This study examined monthly prevalence of obesity and exercise in active component U.S. military members prior to and during the COVID-19 pandemic. Information about obesity (BMI≥30) and self-reported vigorous exercise (≥150 minutes per week) were collected from Periodic Health Assessment (PHA) data. From 1 January 2018 through 31 July 2021, there was a gradual increase in obesity and an overall decrease in vigorous exercise. Comparing the mean monthly percentage of obesity during the 12-month period prior to the pandemic to the 12 months after its start showed an overall increase in obesity (0.43%); however, no obvious spike in the obesity trend was apparent following the onset of the pandemic. The prevalence of vigorous exercise showed an abrupt decrease following the onset of the COVID-19 pandemic, but this change did not coincide with an abrupt change in the obesity trend. These results suggest that the COVID-19 pandemic had a small effect on the trend of obesity in the active component U.S. military and that obesity prevalence continues to increase.

This study examined the rates of depressive symptoms in active component U.S. service members prior to and during the COVID-19 pandemic and evaluated whether SARS-CoV-2 test results (positive or negative) were associated with self-reported depressive symptoms. Depressive symptoms were measured by the Patient Health Questionnaire-2 (PHQ-2) screening instrument and were defined as positive if the total score was 3 or greater. From 1 January 2019 through 31 July 2021, 2,313,825 PHQ-2s were completed with an increase in the positive rate from 4.0% to 6.5% (absolute % difference, +2.5%; relative % change, +67.1%) from the beginning to the end of the period. While there was a gradual increase of 19.8% in the months prior to the pandemic (1.4%/month average), this increase grew to 40.4% during the pandemic (2.5%/month average). However, no association was found between a positive or negative SARS-CoV-2 test result and the PHQ-2 screening instrument result. These findings suggest that the accelerated increase in depressive symptoms is likely a function of the environment of the COVID-19 pandemic instead of the SARS-CoV-2 infection itself. Further research to better understand specific factors of the pandemic leading to depressive symptoms will improve efficient allocation of military medical resources and safeguard military medical readiness.

INTRODUCTION: The primary objective of the current study was to assess factors associated with Human Papillomavirus (HPV) vaccine initiation and compliance in a cohort of active duty US military service members (SM). MATERIALS AND METHODS: We included active-duty participants aged 18-26 years from the Millennium Cohort Study, a longitudinal cohort study of over 200,000 military SMs. The eligible study population included 22,387 female SMs and 31,705 male SMs. Vaccination was assessed over the period 2006-2017. Logistic regression was used to estimate the odds of vaccine initiation and compliance (3 doses within a 1-year period) in relation to demographic, military, health, and behavioral characteristics. RESULTS: Among female SMs, 37.8% initiated the vaccine and 40.2% of initiators completed the series within a year. Among male SMs, 3.9% initiated the vaccine and 22.1% of initiators completed the series within a year. Differences by sociodemographic factors, deployment status, branch of service, occupation, and smoking status-but not by selected mental health conditions-were observed. CONCLUSION: HPV vaccination uptake is subpar across all military service branches. Certain subgroups of SMs could be targeted to increase overall HPV vaccine coverage in the US military population.
RESUMO
Previous research suggests active duty service members (ADSM) experience higher rates of human papilloma virus infection and cervical dysplasia, which puts them at greater risk for cervical cancer. The current study examined crude rates and correlates of cervical cancer screening compliance in 2003-2015 among screening-eligible ADSM in the Millennium Cohort Study (MCS). Data were drawn from the MCS, Defense Manpower Data Center, and Military Health System Data Repository. Screening eligibility and compliance were calculated each year and initial analyses examined crude rates of compliance. Generalized estimating equations were calculated to determine whether sociodemographic, military, and mental/behavioral health covariates were associated with cervical cancer screening compliance. A majority of participants were 21-29 years old (79.4%), non-Hispanic White (60.6%), and enlisted (82.2%). Crude rates of cervical cancer screening compliance increased from 2003 (61.2%) to 2010 (83.1%), and then declined from 2010 to 2015 (59.8%). Older ADSM and those who had a history of deployment had lower odds of screening compliance. ADSM in the Air Force and those in healthcare occupations had higher odds of screening compliance. Study findings suggest that cervical cancer screening compliance is declining among ADSM. Interventions to improve screening should target groups with lower screening compliance.
RESUMO
Behaviour problems are a leading reason for dogs being relinquished to rescue centres across the world every year. The aim of this study was to investigate whether free behavioural advice would be accepted at the point of an owner requesting to relinquish their dog for behavioural reasons. The call records of 1131 relinquishment requests were reviewed and analysed to establish if the offer of free behaviour advice was accepted. The results showed that advice was accepted in 24.4% of relinquishment requests and behavioural problem was a significant predictor of whether advice was accepted (p < 0.001). The odds of advice being accepted were 5.755 times (95% CI: 2.835-11.681; p < 0.001) greater for a relinquishment request due to problems with general management behaviours compared to aggression between dogs in the home, representing 4.2% and 20.2% of overall relinquishment requests. These data suggest that owners are prepared to accept behaviour advice at the point of relinquishment request, so advice interventions could have potential to impact the levels of dog relinquishment to rescue centres. The impact of an intervention offering behaviour advice may be limited by overall levels of advice acceptance by owners and therefore complimentary proactive solutions to reduce behavioural relinquishments should also be considered.
RESUMO
The objective of this study was to assess the incidence and trends of sepsis hospitalizations in the active component U.S. military over the past decade. Between 1 January 2011 and 31 December 2020, there were 5,278 sepsis hospitalizations of any severity recorded among the active component. The overall incidence was 39.8 hospitalizations per 100,000 person-years (p-yrs). Annual incidence increased 64% from 2011 through 2019, then dropped considerably in 2020. Compared to their respective counterparts, rates were highest among female service members, the oldest and youngest age groups, and recruits. The gap in sepsis hospitalization rates between female and male service members increased over the surveillance period. Pneumonia was the most commonly co-occurring infection, followed by genitourinary infections. Among female service members, genitourinary infections were more commonly diagnosed compared to pneumonia. The most common non-infection co-occurring diagnoses were acute kidney failure and acute respiratory failure. This study demonstrates an apparent sex disparity in sepsis rates and further study is recommended to understand its cause.

The objective of this study was to assess overall vaccine initiation and completion in the active component U.S. military, with a focus on racial/ethnic disparities. From 11 December 2020 through 12 March 2021, a total of 361,538 service members (27.2%) initiated a COVID-19 mRNA vaccine. Non-Hispanic Blacks were 28% less likely to initiate vaccination (95% confidence interval: 25%-29%) in comparison to non-Hispanic Whites, after adjusting for potential confounders. Increasing age, higher education levels, higher rank, and Asian/Pacific Islander race/ethnicity were also associated with increasing incidence of initiation after adjustment. When the analysis was restricted to active component health care personnel, similar patterns were seen. Overall, 93.8% of those who initiated the vaccine series completed it during the study period, and only minor differences in completion rates were noted among the demographic subgroups. This study suggests additional factors, such as vaccine hesitancy, influence COVID-19 vaccination choices in the U.S. military. Military leadership and vaccine planners should be knowledgeable about and aware of the disparities in vaccine series initiation.

Long-acting reversible contraceptives (LARCs) are highly effective means of birth control that can improve service women's overall health and readiness. This report expands upon prior data and summarizes the annual prevalence (overall and by demographics) of LARC use from 2016 through 2020 among active component U.S. service women, compares LARC prevalence to the prevalence of short-acting reversible contraceptives (SARCs), and evaluates the probability of continued use of LARCs by type. LARC use increased from 21.9% to 23.9% from 2016 through 2019 while SARC use decreased from 28.3% to 24.9%. Both SARC and LARC use decreased in 2020 which may have been related to the coronavirus disease 2019 (COVID-19) pandemic. The prevalence of intrauterine devices (IUDs) was greater than implants, and IUDs also had a higher probability of continuation than implants. At 12 months, the continuation for IUDs was 81% compared to 73% for implants. At 24 months, the probabilities of continuation were 70% for IUDs and 54% for implants. Probabilities of continuation were similar across outsourced care and direct care settings. The increased use of LARCs along with their high frequency of continuation in U.S. service women may have a positive impact on overall health and readiness.

This report documents the numbers of air evacuations for diagnoses of coronavirus disease 2019 (COVID-19) among U.S. active duty service members (ADSMs) from locations in U.S. Central Command (CENTCOM) and U.S. European Command (EUCOM) areas of responsibility. Counted were COVID-19 evacuations both within and out of each of the theaters from 11 March through 30 September 2020. Of the 186 evacuations originating in CENTCOM, 185 resulted in the patients arriving at Landstuhl in EUCOM and 1 was within theater. A total of 169 of the CENTCOM evacuations took place in June through August 2020 and only 1 occurred in September. Of the 39 air evacuations originating in EUCOM, 38 were intra-theater transfers and 1 was to a CONUS facility. Most (n=32) of the EUCOM evacuations occurred in September. Evacuees were most often members of the Army (71%), enlisted personnel (63%), males (91%), and aged 30 years or older (58%). Among a random sample of 56 evacuees, 20% were asymptomatic. Among those with symptoms, the most common were cough, fatigue, congestion, headache, and sore throat.

BACKGROUND: The tetanus, diphtheria, and acellular pertussis (Tdap) vaccine was approved for U.S. adults in 2005 and recommended for administration in every pregnancy in 2012, with optimal timing between 27 and 36 weeks' gestation. In the military, however, a current Tdap vaccination status is compulsory for service, and active duty women may be inadvertently exposed in early pregnancy. Safety data in this population are limited. OBJECTIVES: To assess safety of inadvertent (0-13 weeks' gestation) and recommended (27-36 weeks' gestation) exposure to the Tdap vaccine in pregnancy. METHODS: Pregnancies and live births from Department of Defense Birth and Infant Health Research program data were linked with military personnel immunization records to determine pregnancy Tdap vaccine exposure among active duty women, 2006-2014. Multivariable Cox and generalized linear regression models estimated associations between Tdap vaccine exposure and adverse pregnancy or infant outcomes. RESULTS: Of 145,883 pregnancies, 1272 were exposed to the Tdap vaccine in the first trimester and 9438 between 27 and 36 weeks' gestation. Neither inadvertent nor recommended vaccine exposure were associated with spontaneous abortion, preeclampsia, or preterm labor. Among 117,724 live born infants, 984 were exposed to the Tdap vaccine in the first trimester and 9352 between 27 and 36 weeks' gestation. First trimester exposure was not associated with birth defects, growth problems in utero, growth problems in infancy, preterm birth, or low birth weight. Tdap vaccine exposure between 27 and 36 weeks' gestation was not associated with any adverse infant outcome. CONCLUSIONS: Among a population of active duty women in the U.S. military who received the Tdap vaccine during pregnancy, we detected no increased risks for adverse maternal, fetal, or infant outcomes. Our findings corroborate existing literature on the safety of exposure to the Tdap vaccine in pregnancy.

BACKGROUND: Malaria in pregnancy can cause severe maternal and fetal complications. Chloroquine (CQ) and mefloquine (MQ) are recommended for chemoprophylaxis in pregnancy, but are not always suitable. Atovaquone-proguanil (AP) might be a viable option for malaria prevention in pregnancy, but more safety data are needed. METHODS: Data for pregnancies and live births among active duty military women, 2003-2014, from the Department of Defense Birth and Infant Health Research program were linked with pharmacy data to determine antimalarial exposure. Multivariable Cox and logistic regression models were used to assess the relationship of antimalarial exposure with fetal and infant outcomes, respectively. RESULTS: Among 198,164 pregnancies, 50 were exposed to AP, 156 to MQ, and 131 to CQ. Overall, 17.6% of unexposed pregnancies and 28.0%, 16.0%, and 6.1% of pregnancies exposed to AP, MQ, and CQ, respectively, ended in fetal loss (spontaneous abortion or stillbirth) (adjusted hazard ratios [aHR] = 1.46, 95% confidence interval [CI] 0.87-2.46; aHR = 1.06, 95% CI 0.72-1.57; and aHR = 0.47, 95% CI 0.24-0.94, respectively). CONCLUSIONS: The small number of AP exposed pregnancies highlights the difficulty in assessing safety. While definitive conclusions are not possible, these data suggest further research of AP exposure in pregnancy and fetal loss is warranted. TWITTER LINE: More research on fetal loss following atovaquone-proguanil exposure in pregnancy is warranted.
RESUMO
UNLABELLED: The views expressed in this article are those of the authors and do not necessarily reflect the official policy or position of the Uniformed Services University of the Health Sciences, Department of the Navy, Department of Defense or the U. S. government. Dr. Wells is a military service member (employee of the U.S. government). This work was prepared as a part of her official duties. Title 17, USC Section 101 defines a U.S. government work as a work prepared by a military service member or employee of the U.S. government as part of the person's official duties. Despite substantial reductions in U.S. infant mortality rates, racial disparities persist, with black Americans experiencing 2.4 times the rate of their white counterparts. Low birthweight and preterm delivery contribute to this disparity. METHODS: To examine the association between antepartum nurse case management home visitation and the occurrence of low birthweight and preterm deliveries in African-American women in Montgomery County, MD, a retrospective cohort study was conducted using existing data from 109 mothers who were enrolled in the Black Babies Start More Infants Living Equally Healthy (SMILE) program. Logistic regression analysis was used. RESULTS: Women who received antepartum home visits were 0.37 (CI 0.15-0.94) times less likely to experience preterm delivery than women who did not receive antepartum home visits. The effect of antepartum home visits on preterm delivery was independent of level of prenatal care, negative life events and number of prior live births. There was no significant association between antepartum home visits and low birthweight. CONCLUSION: Antepartum home visits appeared to be protective against preterm delivery and could contribute to reducing racial disparities in infant mortality. Further study is needed to understand and replicate specific program components that may contribute to improved birth outcomes in African-American women.
