Objective: To examine the effect of gender affirming hormones on athletic performance among transwomen and transmen.

Methods: We reviewed fitness test results and medical records of 29 transmen and 46 transwomen who started gender affirming hormones while in the United States Air Force. We compared pre- and post-hormone fitness test results of the transwomen and transmen with the average performance of all women and men under the age of 30 in the Air Force between 2004 and 2014.

Article Synopsis
  • Limited evidence exists for pharmacogenetic (PGx) testing in children, prompting a study of 452 patients to explore its utility and future research targets.
  • The study found that 98.7% of patients had actionable gene-drug pairs, with 203 actionable gene-drug-diagnosis groups identified, indicating potential for PGx to guide treatment.
  • Key genes CYP2C19, CYP2D6, and CYP3A5 emerged as crucial in matching diagnoses with actionable prescriptions, suggesting mood disorders and gastritis/esophagitis as priority areas for further PGx research.

Background: Unplanned pregnancy is a common problem among United States servicewomen. Variation among service branches in contraceptive education and access during initial training is associated with differences in contraceptive use and childbirth rates despite access to a uniform health benefit including no-cost reproductive healthcare and contraception. However, it is unclear whether changes in branch-specific contraceptive policies can influence reproductive outcomes among junior enlisted women in that service branch.

Objective: Assess the influence of healthcare utilization on previously reported associations between contraception initiation, diagnosis of depression, and dispensing of antidepressant medications.

Study Design: Retrospective cohort analysis of insurance records from 272,693 women ages 12-34 years old enrolled in the United States Military Healthcare System in September 2014 and followed for 12 months. We compared outcomes of women who initiated hormonal contraception with all women eligible for care and then with women who accessed care during the study month using Kaplan-Meier and Cox proportional hazards analyses.

Introduction: Transgender and gender-diverse (TGD) youth are at greater risk for mental health and medical conditions than their cisgender peers; however, poor health outcomes and identity-based discrimination can be minimized in the context of optimal support. Approximately 1.7 million youth may be eligible for care covered by the Military Health System, which includes mental health and gender-affirming medications.

The Centers for Disease Control and Prevention suggests screening for Trichomonas vaginalis infection might be considered in high-prevalence populations. High asymptomatic infection rates and poor sensitivity of clinical diagnosis make it difficult to estimate local prevalence. Testing of ThinPrep samples can provide an estimate of local Trichomonas vaginalis infection rates and guide screening practices.

Background: Long-acting reversible contraception is more effective for pregnancy prevention than shorter-acting contraceptive methods and has the potential to reduce healthcare disparities and costs. However, long-acting reversible contraception is underused in the United States. One population of interest is beneficiaries of the United States military healthcare system who have access to universal healthcare, including no-cost, no-copay contraception with unlimited method switching, and comprise a large, actual use cohort.

Objective: The purpose of this project was to improve provider documentation of adolescent overweight and obesity through body mass index percentile (BMI%) documentation in the military's electronic medical record (EMR).

Methods: Using the FOCUS-PDCA (Find-Organize-Clarify-Understand-Select-Plan-Do-Check-Act) model, we developed an intervention to improve rates of diagnosis of overweight/obesity in our adolescent medicine clinic. Medical technicians documented the patient's BMI% and growth chart in the EMR.

This article's goals are to identify the characteristics of abusive heterosexual dating relationships among adolescents. Using the National Longitudinal Study of Adolescent Health dataset, an analysis of 4,441 heterosexual relationships was completed using logistic regression models (SAS PROC GENMOD). The associations between being verbally and physically abused were examined with respect to the following relationship characteristics: involvement in sexual intercourse or pregnancy with the relationship partner, description of the relationship as a "special romantic relationship," duration of the relationship, age at relationship initiation, and age difference between partners.

Purpose: The purpose of this study was to determine the associations between verbal and minor physical abuse by an intimate partner and reproductive health behavior.

Methods: Logistic regression analyses of 1996 cross-sectional data from 973 sexually active, dating female adolescents surveyed for wave II of the National Longitudinal Study of Adolescent Health Public Use Dataset examining the relationship between abuse by an intimate partner and reproductive health. We measured verbal (insulted in public, sworn at, or threatened with violence) and minor physical (threw something at them, pushed them, or shoved them) abuse by any intimate partner during the past 18 months and by any current intimate partner.
