Indicators of asthma control among students in a rural, school-based asthma management program

Abstract Objective: The evaluation sought to determine if a comprehensive, school-based asthma management program in a small, rural school district helped students improve asthma control. Methods: To determine if students in the asthma program demonstrated better asthma control than students in a comparison school district, the evaluation team used a quasi-experimental, cross-sectional design and administered questionnaires assessing asthma control (which included FEV1 measurement) to 456 students with asthma in the intervention and comparison districts. Data were analyzed for differences in asthma control between students in the two districts. To determine if students in the intervention experienced increased asthma control between baseline and follow-up, the evaluation team used a one-group retrospective design. Program records for 323 students were analyzed for differences in percent of predicted forced expiratory volume in one second (FEV1) between baseline and follow-up. Results: Students with asthma in the intervention district exhibited significantly better asthma control than students with asthma in the comparison district. Percent of predicted FEV1 did not change significantly between baseline and follow-up for the intervention participants; however, post hoc analyses revealed students with poorly controlled asthma at baseline had significantly higher FEV1 scores at follow-up, and students with well-controlled asthma at baseline had significantly lower FEV1 scores at follow-up. Conclusions: Findings suggest that the comprehensive school-based program led to improvements in asthma control for students with poorly controlled asthma at baseline, and school-based programs need mechanisms for tracking students with initially well-controlled asthma to ensure they maintain control.

Early Sexual Debut and Associated Risk Behaviors Among Sexual Minority Youth

INTRODUCTION Early sexual debut, sexual risk taking, substance use, violent victimization, and suicidal behaviors are more prevalent among sexual minority than sexual nonminority youth. Although associations between early sexual debut and these risk behaviors exist, little is known about such associations among sexual minority youth. This study examined these associations among sexual minority U.S. high school students and their sexual nonminority peers. METHODS In 2015, the national Youth Risk Behavior Survey included questions assessing sexual orientation for the first time. In 2016, data from this nationally representative sample of 15,624 U.S. high school students were analyzed to determine if associations between early sexual debut and other health risk behaviors varied by sexual orientation, by calculating adjusted (for sex, race/ethnicity, and age) prevalence ratios (APRs). RESULTS Associations between early sexual debut and other health risk behaviors did not vary significantly by sexual orientation. Early sexual debut (first sexual intercourse before age 13 years) was associated with sexual risk taking, substance use, violent victimization, and suicidal thoughts/attempts among students identifying as lesbian, gay, or bisexual (LGB) and among students identifying as heterosexual, for example, being currently sexually active (LGB students: APR=1.82, 95% CI=1.35, 2.45; heterosexual students: APR=2.50, 95% CI=2.22, 2.81) and not using a condom at last sexual intercourse (LGB students: APR=1.50, 95% CI=1.18, 1.91; heterosexual students: APR=1.29, 95% CI=1.09, 1.52). CONCLUSIONS School-based sexual health programs might appropriately utilize strategies that are inclusive of sexual minority students, encourage delay of sexual intercourse, and coordinate with violence and substance use prevention programs.

High School Students' Self-Reported Use of School Clinics and Nurses.

Access to school health clinics and nurses has been linked with improved student achievement and health. Unfortunately, no studies have examined how many students report using school clinics or nurses and for which services. This study addressed this gap with data from a nationally representative sample of 15- to 25-year-olds. Respondents who reported being in high school were provided a list of services and asked whether they had gone to a school nurse or clinic for any of the listed services. Nearly 90% reported having access to a school clinic or nurse. Among students with access, 65.6% reported using at least one service. Non-White students and younger students were more likely to report having access to a clinic or nurse. These results show many students have access to clinics or nurses and are using these services, although not uniformly for all services.

The optimal age for screening adolescents and young adults without identified risk factors for HIV

PURPOSE To assess the optimal age at which a one-time HIV screen should begin for adolescents and young adults (AYA) in the U.S. without identified HIV risk factors, incorporating clinical impact, costs, and cost-effectiveness. METHODS We simulated HIV-uninfected 12-year-olds in the U.S. without identified risk factors who faced age-specific risks of HIV infection (.6-71.3/100,000PY). We modeled a one-time screen (

/year-of-life saved (YLS) from the health-care system perspective. In sensitivity analyses, we varied HIV incidence, screening and linkage rates, and costs. RESULTS All one-time screens detected a small proportion of lifetime infections (.1%-10.3%). Compared with current U.S. screening practices, a screen at age 25 led to the most favorable care continuum outcomes at age 25: proportion diagnosed (77% vs. 51%), linked to care (71% vs. 51%), retained in care (68% vs. 44%), and virologically suppressed (49% vs. 32%). Compared with the next most effective screen, a screen at age 25 provided the greatest clinical benefit, and was cost-effective (

100,000/YLS). CONCLUSIONS For U.S. AYA without identified risk factors, a one-time routine HIV screen at age 25, after the peak of incidence, would optimize clinical outcomes and be cost-effective compared with current U.S. screening practices. Focusing screening on AYA ages 18 or younger is a less efficient use of a one-time screen among AYA than screening at a later age.

Targeting Human Immunodeficiency Virus Pre-Exposure Prophylaxis to Adolescent Sexual Minority Males in Higher Prevalence Areas of the United States: A Modeling Study

PURPOSE Adolescent sexual minority males (ASMM) comprise a high-risk group that may benefit from expanded human immunodeficiency virus (HIV) and sexually transmitted disease (STD) prevention services. The purpose of this study was to estimate the prevalence of HIV and STD testing among ASMM from pooled high school Youth Risk Behavior Surveys (YRBSs). METHODS Data came from 26 YRBSs from 2005 to 2013, which included questions on sexual identity and/or sex of sexual contacts and questions on ever being tested for HIV and/or STDs. Multivariable logistic regression was used to identify factors independently associated with lifetime HIV testing among sexually experienced ASMM. RESULTS Overall, 3027 of 43,037 (6.3%, 95% confidence interval [CI]: 5.8%-6.8%) males were categorized as ASMM. Among 1229 sexually experienced ASMM, 413 (26.6%, 95% CI: 21.8%-31.4%) reported ever being tested for HIV, and among 571 ASMM who reported not using a condom during last intercourse, 192 (29.4%, 95% CI: 21.3%-37.6%) reported testing. A longer duration since first intercourse (≥3 vs. ≤1 year: adjusted prevalence ratio [aPR]: 1.6, 95% CI: 1.0-2.6) and recent intercourse (within the past 3 months vs. earlier: aPR: 2.2, 95% CI: 1.4-3.4) was associated with a higher adjusted prevalence of HIV testing. Sixty-four of 252 (30.2%, 95% CI: 20.0%-40.4%) sexually experienced ASMM reported ever being tested for STDs. CONCLUSION Low levels of testing among sexually experienced ASMM, particularly those who reported sex without a condom at last intercourse, highlight the exigency of improving age-appropriate HIV and STD prevention services. Educating healthcare providers to better assess adolescent sexual histories is essential to increasing testing.

A multicomponent school-based asthma management program: enhancing connections to clinical care.

ABSTRACT Sexual health education, including HIV prevention information, can help prevent unintended pregnancy and sexually transmitted infections. National Youth Risk Behavior Survey data from 2011 and 2013 were used to determine HIV education prevalence among 9,825 currently sexually active students in grades 9–12. Associations between HIV education and contraceptive methods used at last sexual intercourse were examined for: (1) condom use; (2) any contraceptive method; (3) dual use of a condom and either birth control pills; IUD or implant; or shot, patch, or birth control ring; and (4) primary contraceptive method. Primary contraceptive method options were (1) no method; (2) birth control pills; (3) condoms; (4) IUD or implant; (5) shot, patch, or birth control ring; (6) withdrawal or some other method; and (7) not sure. Logistic regression (prevalence ratios [PRs] and 95% confidence intervals [CIs]) and Chi-squares were used for testing. Students who received HIV education were more likely than students who did not to use a condom (PR:1.09;CI:1.01,1.18) and any contraceptive method (PR:1.08;CI:1.04,1.12); there was no significant association with dual use. Primary contraceptive method varied significantly by receipt of HIV education (p < .001). School-based HIV education may be important for promotion of adolescent condom and contraceptive use.
