RESUMO
This report describes ivermectin prescription fill rates among U.S. active component service members (ACSM) over time during the early phases of the COVID-19 pandemic. Information about the unsubstantiated benefits of ivermectin for coronavirus 2019 (COVID-19) prevention and treatment was widely available online early in the COVID-19 pandemic. Ivermectin prescription fill rates increased among ACSM during periods of Alpha and Delta coronavirus variant predominance, but not during the predominance of the Omicron variant. At the peak of the fill rate curve, in August 2021, rates were higher among men compared to women, older compared to younger age groups, senior officers compared to junior officers, senior enlisted compared to junior enlisted service members, and those with a bachelor's or advanced degree compared to those without a bachelor's degree. Ivermectin prescriptions were more likely to have been filled at a retail pharmacy than at a military hospital or clinic. During the COVID-19 pandemic fill rates for ivermectin prescriptions among ACSM increased, including those without a qualifying diagnosis. Rates peaked in August 2021 but subsequently declined. The decrease in ivermectin fill rates was coincident with vigorous efforts to correct previous misinformation and implement pre-authorization requirements for prescriptions. Research on the impact of unproven online claims about clinical and public health interventions has potential to curtail future unnecessary and potentially harmful treatments.

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.

INTRODUCTION: We describe celiac disease epidemiology in the US military population. METHODS: This is a population-based study from data collected between 2000 and 2021. Incidence and prevalence rates and descriptive statistics for demographics are presented. RESULTS: Overall, 2248 incident cases of celiac disease were identified. The incidence rate increased from 1.2 to 14.0 per 100,000 person-years and the overall lifetime prevalence increased from 3.1 to 57.4 per 100,000 service members. In gastroenterology clinics, the incidence rate increased from 1.4 to 8.2 per 100,000 person-years, while prevalence increased from 3.3 to 33.4 per 100,000 service members. DISCUSSION: In this study, celiac disease incidence and prevalence increased significantly.

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
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.

This study evaluated trends in the prevalence of overweight, obesity, and diabetes among active component service members between 2018 and 2021, before and after the start of the COVID-19 pandemic. This study also investigated the incidence of prediabetes and type 2 diabetes mellitus (T2DM) diagnoses during the same period. Between 2018 and 2021, the prevalence of obesity among active component service members who completed a Periodic Health Assessment (PHA) increased from 16.1% to 18.8%. The incidence of prediabetes increased from 588.2 to 763.8 cases per 100,000 person-years (p-yrs), and the incidence of T2DM increased from 55.5 to 69.6 per 100,000 p-yrs. The largest relative increases in obesity prevalence were in the youngest (<30 years) age categories. Navy members and Hispanic service members experienced the largest absolute and relative increases in rates of new diabetes diagnoses. These findings indicate that during the COVID-19 pandemic active component service members experienced increased prevalence of obesity, prediabetes, and diabetes. Evaluation of lifestyle factors associated with these chronic diseases among service members may be useful to enhance deployment readiness and operational effectiveness.

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.

Objectives: Cisgender gay, bisexual, and other men who have sex with men and transgender women experience HIV incidence disparities in Senegal. These analyses determined how depression and different stigma mechanisms related to sexual behavior are associated with healthcare access, sexually transmitted infection testing, and HIV testing among cisgender gay, bisexual, and other men who have sex with men and transgender women across three cities in western Senegal. Methods: Logistic regression assessed the relationship of three stigma scales (stigma from family and friends, anticipated healthcare stigma, and general social stigma) and depression with these outcomes. Results: Depression and stigma were not associated with healthcare access, sexually transmitted infection testing, or HIV testing. However, individuals who had disclosed their sexual identity to a medical provider were more likely to test for HIV. Conclusions: Sexual behavior stigma experienced by cisgender gay, bisexual, and other men who have sex with men and trans women in Senegal may not limit access to routine healthcare, but may limit disclosure of sexual orientation and practices, limiting access to appropriate HIV prevention services.
RESUMO
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.

The validity of military hepatitis C virus (HCV) surveillance data is uncertain due to the potential for misclassification introduced when using administrative databases for surveillance purposes. The objectives of this study were to assess the validity of the surveillance case definition used by the Medical Surveillance Monthly Report (MSMR) for HCV, the over and underestimation of cases from surveillance data, and the true burden of HCV disease in the U.S. military. This was a validation study of all potential HCV cases in the active component U.S. military from calendar year 2019 obtained using several different data sources: 1) outpatient, inpatient, and reportable medical event (RME) records in the Defense Medical Surveillance System, 2) Health Level 7 (HL7) laboratory data obtained from the Navy Marine Corps Public Health Center, and 3) chart review of the electronic medical records of all potential HCV cases, to include those from privately-sourced care. The sensitivity of the MSMR case definition was 83.6% and the positive predictive value (PPV) was 60.0%. This study suggests that the U.S. military should have confidence that the previous estimates derived using the MSMR surveillance case definition were moderately close to the true burden of incident chronic HCV infection (the true incidence of chronic disease being about 27% lower), but these reports likely dramatically overestimate the incidence of acute HCV. Since HCV was selected as an RME to guide public health action, it is most suitable to invest public health efforts in strengthening the use of confirmed RMEs as the surveillance case definition.
