RESUMO
In the US, few adolescents get adequate school night sleep, largely due to early school start times. In the START study we aimed to test the following hypothesis: That following the implementation of later high school start times students have lesser longitudinal increases in body mass index (BMI) and shift to more healthful weight-related behaviors relative to students attending schools that retain early start times. The study enrolled a cohort of students (n = 2426) in five high schools in the Twin Cities, MN metro. Heights and weights were measured objectively, and surveys were administered annually from 9th through 11th grades (2016-2018). All study schools started early (either 7:30 am or 7:45 am) at baseline (2016). At follow-up 1 (2017) and continuing through follow-up 2 (2018), two schools delayed their start times by 50-65 min, while three comparison schools started at 7:30 am throughout the observation period. Using a difference-in-differences natural experiment design, we estimated differences in changes in BMI and weight-related behaviors over time between policy change and comparison schools. Students' BMIs increased in parallel in both policy change and comparison schools over time. However relative to changes in comparison schools after the start time shift, students in policy change schools had a modestly more healthful profile of weight-related behaviors - for instance they had a relatively greater probability of eating breakfast, having supper with their family, getting more activity, eating fast food less frequently, and eating vegetables daily. Later start times could be a durable, population-wide strategy that promotes healthful weight behaviors.

OBJECTIVES: We sought to examine the effects of high school start time delay, a proven sleep-promoting intervention, on sugary beverage (SB) consumption among U.S. adolescents. METHODS: In the Spring of 2016 (baseline), the START study recruited 2134 ninth grade students who were enrolled high schools in the Twin Cities, MN metropolitan area. These participants were surveyed again in their 10th and 11th grade years, in Spring 2017 and 2018 (follow-ups 1 and 2). All five high schools started early (7:30 or 7:45 a.m.) at baseline. By follow-up 1, two "policy change" schools shifted their start times later (8:20 or 8:50 a.m.) and maintained these later start times through follow-up 2 while three "comparison schools" retained an early start time at all time points. Generalized estimating equations using a negative binomial distribution were used to obtain estimates of the number of sugary beverages consumed per day at each wave as well as the difference in difference (DiD) estimates between baseline and each follow-up period comparing policy change to comparison schools. RESULTS: Mean baseline sugary beverage consumption was 0.9 (1.5) beverages per day in policy change schools and 1.2 (1.7) beverages per day in the comparison schools. While there was no evidence of impact of start time change on total SB consumption, DiD estimates revealed a small decrease in the number of caffeinated sugary beverages consumed between baseline and the second follow-up period in students attending the policy change schools relative to comparison schools in both crude (0.11/day reduction, p-value = 0.048) and adjusted analyses (0.11/day reduction, p-value = 0.028). CONCLUSION: Although the differences in this study were quite modest, a population-wide reduction in sugary beverage consumption could have public health benefit.

INTRODUCTION: Delaying high school start times extends adolescents' nightly sleep, but it is less clear how it affects educational outcomes. We expect links between school start time delays and academic performance because getting enough sleep is a key input to the cognitive, health, and behavioral factors necessary for educational success. Thus, we evaluated how educational outcomes changed in the 2 years following a school start time delay. METHODS: We analyzed 2153 adolescents (51% male, 49% female; mean age 15 at baseline) from START/LEARN, a cohort study of high school students in the Minneapolis-St. Paul, MN, USA metropolitan area. Adolescents experienced either a school start time delay ("policy change schools") or consistently early school start times ("comparison schools"). We compared patterns of late arrivals, absences, behavior referrals, and grade point average (GPA) 1 year before (baseline, 2015-2016) and 2 years after (follow-up 1, 2016-2017 and follow-up 2, 2017-2018) the policy change using a difference-in-differences analysis. RESULTS: A school start time delay of 50-65 min led to three fewer late arrivals, one fewer absence, a 14% lower probability of behavior referral, and 0.07-0.17 higher GPA in policy change schools versus comparison schools. Effects were larger in the 2nd year of follow-up than in the 1st year of follow-up, and differences in absences and GPA emerged in the second year of follow-up only. CONCLUSIONS: Delaying high school start times is a promising policy intervention not only for improving sleep and health but for improving adolescents' performance in school.

We developed and pilot tested a 3-month HIV self-testing intervention called HiSTEP ("HIV Self-testing Engagement Project") among 95 adult (18+ years) at-risk (condomless sex < 3 months) adults in Kampala, Uganda. HiSTEP leverages theoretically-grounded (in the Information-Motivation-Behavioral Skills model) text messages, a telehealth centre with live support, and "last-mile" HIV self-testing kit delivery to a location chosen by the participant. Nearly 94% of participants were retained at month 3. HIV self-testing was highly acceptable across age and gender groups (94% very satisfied), although older women had slightly lower acceptability ratings (92% very satisfied). Only 13% of participants used HIV self-testing prior to enrollment. Over the 3-month study period, 86% of participants ordered a total of 169 HIV self-testing kits (69% for participant use; 31% for use by others). Findings show that the intervention approach taken in HiSTEP may be particularly valuable for engaging at-risk Ugandan adults in HIV self-testing using a novel technology-assisted promotion and delivery method.

After an outbreak of meningococcal B (MenB) disease at a university, we surveyed students regarding their vaccination status 2 months and 20 months after campus-led vaccination campaigns and compared students' self-report to vaccination records. Nearly all participants accurately reported the number of vaccine doses at both visits. Among those who received two doses of the vaccine, accurate recall of the timing of MenB vaccination was 85.7% (95% CI: 82.7-88.6) in the short term and 62.9% (95% CI: 56.0-69.8) in the long term. After the outbreak, only one-third reported feeling 'very confident' in their MenB disease and vaccine knowledge. Our findings suggest that the validity of self-reported vaccination status among university students in an outbreak setting is high, but that if the duration of protection is unknown and additional doses of vaccine may be needed, documented vaccination records may be preferred over self-report to assess timing of vaccine receipt.

We pilot tested the Status Update Project (SUP) mobile app intervention to promote repeat HIV testing among HIV-negative US MSM. Participants (Mean age = 29 years; 51% racial/ethnic minority; 63% single) who were eligible and enrolled were randomized to either the SUP mobile app or a no-treatment condition, with assessments at baseline and month 4 and 8. Eighty-three percent of men were retained at the 8-month follow up. Among men randomized to the SUP arm, the app's ease and simplicity, health information, HIV testing locator, and HIV test reminders were most liked. At month 4, men randomized to the SUP arm were more likely to be repeat testers compared to those in the control arm (RR = 4.4; 95% CI 0.9, 19.9), although differences diminished by month 8 (RR = 1.2; 95% CI 0.8, 2.0). These findings add to our understanding of how mHealth interventions may play an important role in encouraging repeat HIV testing among MSM.

Advancing HIV behavioral science and its integration with recent biomedical prevention strategies-treatment as prevention and pre-exposure prophylaxis (PrEP)-is complicated because traditional definitions of sexual risk (condomless anal sex [CAS] or CAS with a serodiscordant partner) may not suffice given the success of biomedical prevention in the absence of condoms. To better understand how to define and understand risk in the era of biomedical HIV prevention, we assessed correlates of four different definitions of high-risk sexual behavior among a sample of 401 adult HIV-positive MSM (57% African American) residing in the New York City area: (1) a traditional model of risk defined as CAS with an HIV-negative or unknown serostatus partner; (2) a definition that considered participant viral load (VL); (3) a definition that considered partner PrEP use; and (4) a definition that considered participant HIV VL and partner PrEP use. Among participants reporting anal sex (n = 281) with a man in the past 3 months, 42% were considered high risk under Definition 1, 6% under Definition 2, 25% under Definition 3, and 2% under Definition 4. Correlates of risk varied across definitions. For example, while education was the strongest predictor of high-risk sexual behavior in Definitions 1 and 2, alcohol use and enacted stigma were the strongest predictors in the model that only accounted for partner PrEP use (Definition 3). These findings have implications for whom to reach for intervention efforts, the difficulty in meeting recruitment goals, and the types of interventions that should be used.

OBJECTIVES: To assess awareness of cytomegalovirus (CMV); attitudes towards screening; and frequency of behaviors that could increase the risk of prenatal infection. METHODS: We conducted a survey among 726 women at the 2017 Minnesota State Fair. Minnesota residents aged 18-44 were eligible if they had never been pregnant or had been pregnant within the past 10 years. We compared responses between never-pregnant and recently-pregnant women. RESULTS: Only 20% of study participants had previously heard of CMV. Remarkably, recently-pregnant women were no more likely to be aware of CMV than never-pregnant women after adjusting for potential confounders. After receiving information about CMV, nearly all participants indicated they believed prenatal (96%) or newborn (96%) screening should be offered. CONCLUSIONS: Although baseline awareness of CMV was low (even among recently-pregnant women), after learning more about the risks, women supported screening. Several states have passed or proposed legislation promoting CMV education and/or screening programs. We identified important gaps in knowledge about CMV among women who may benefit from education about how to reduce their risk of exposure and who may need to decide whether they would be willing to screen for CMV in the future.

APP+ is a theoretically-grounded mobile app intervention to improve antiretroviral (ART) adherence among men who have sex with men (MSM) who use stimulants. We assessed the feasibility and acceptability of APP+ in a six-month randomized controlled trial among a national sample of 90 MSM recruited online; secondarily, we examined changes in self-reported ART adherence by study arm. Retention at the final assessment was 82%, and acceptability ratings were comparable to other technology-based interventions. MSM in the APP+ group reported higher self-reported percentage ART adherence in the past 30 days at the four-month timepoint compared to a no-treatment control group (89.0% vs. 77.2%). However, once access to the app was removed after month four, group differences in ART adherence diminished by month six. APP+ may be a potentially promising intervention approach for MSM living with HIV who use stimulants but would require enhancements to optimize acceptability and demonstrate more sustained effects.

Using data from eligible participants, we evaluated procedures of a multi-step enrollment process for an mHealth, pilot randomized controlled trial aimed to promote regular HIV testing among at-risk, diverse sexual minority men. Completion rates of eligible participants were calculated and characterized for these enrollment procedures. Among 3058 men who screened, 183 were eligible and 113 enrolled. Two groups emerged: "As planned" (n = 98) followed enrollment directions as designed; "Laggers" (n = 15) did not follow these directions and required additional efforts resulting in mixed results for improving enrollment. Findings suggest the need for pre-determined enrollment decision rules based on available resources.

OBJECTIVE: Marijuana is the most commonly used illicit drug in the United States and co-use with tobacco is increasing. Preliminary studies have indicated that marijuana may suppress luteinizing hormone (LH) or shorten the luteal phase. Although the literature is mixed, these sex hormones may play a role in smoking cessation outcomes. This secondary subgroup analysis aims to explore the menstrual cycle of females who co-use marijuana and tobacco compared with females who only use tobacco in a sample of tobacco treatment-seeking individuals. METHODS: Female participants, aged 18 to 50 years, who self-reported regular menstrual cycles and co-use of marijuana and tobacco were matched 1:3 by age to participants who only use tobacco. Length of the follicular and luteal phases was determined using First Response Urine LH tests. Wilcoxon 2-sample t tests were used to determine differences in phase lengths between groups. RESULTS: Thirteen women who co-use marijuana and tobacco, and 39 women who only use tobacco were included in this analysis. Overall, participants were 37.3â±â8.0 (SD) years of age, mostly Caucasian (67%), and smoked 12.6â±â5.2 (SD) cigarettes per day. The luteal phase length among participants who co-use marijuana and tobacco (11.4 daysâ±â2.2 [SD]) was significantly shorter than among participants who only use tobacco (16.8 daysâ±â11.3 [SD]; Pâ=â0.002). No differences were found in follicular phase length or menstrual cycle length. CONCLUSIONS: These data suggest that females who co-use marijuana and tobacco may have a shortened luteal phase in comparison with females who only use tobacco. Further studies are needed to better understand how marijuana use may impact the menstrual cycle and affect smoking outcomes.

BACKGROUND: Liver fibrosis stage determines risk of morbidity and mortality from chronic hepatitis C virus (HCV) infection. Prior data have shown long-term reversal of liver fibrosis, measured by vibration-controlled transient elastography (VCTE), in patients successfully treated with interferon-based therapies. AIM: Our study sought to determine the effect of treatment with modern HCV direct-acting antiviral (DAA) therapy on noninvasive liver fibrosis measurements. METHODS: A total of 70 patients had VCTE-based liver stiffness measurement (LSM) taken before treatment, directly after treatment completion, and at least 12 months after completion of DAA therapy. Our primary outcome was a >30% improvement in VCTE score at the end of follow-up, relative to baseline. RESULTS: The sustained virologic response rate in our cohort was 95.7%. In our cohort, 34 (48.6%) met the primary outcome. Those who had baseline elevated alanine aminotransferase (OR 3.27; 95% CI 1.13-9.47) and genotype 1 (OR 14.63; 95% CI 1.70-125.83) had higher odds of meeting that outcome, and this remained significant after adjusting for age, baseline body mass index, gender, baseline elevated alkaline phosphatase levels, treatment experience, liver transplant status, smoking, and baseline liver stiffness. CONCLUSION: Treatment of chronic HCV with modern DAA therapy was associated with a significant improvement in LSM by VCTE measurement, suggesting possible early improvement in liver fibrosis along with resolution of inflammation over the first year after treatment completion.

OBJECTIVE: To determine retention in care and virologic suppression among HIV-infected adolescents and young adults attending an adolescent-friendly clinic compared to those attending the standard pediatric clinic at the same site. DESIGN: Retrospective cohort analysis. SETTING: Government supported, hospital-based antiretroviral clinic in KwaZulu-Natal, South Africa. PARTICIPANTS: Two hundred forty-one perinatally HIV-infected adolescents and young adults aged 13 to 24 years attending an adolescent-friendly clinic or the standard pediatric clinic from April 2007 to November 2015. INTERVENTION: Attendance in an adolescent-friendly clinic compared to a standard pediatric clinic. OUTCOMES MEASURES: Retention in care defined as one clinic visit or pharmacy refill in the prior 6 months; HIV-1 viral suppression defined as < 400 copies/ml. RESULTS: Overall, among 241 adolescents and young adults, retention was 89% (214/241) and viral suppression was 81% (196/241). Retention was higher among those attending adolescent clinic (95%) versus standard pediatric clinic (85%; OR 3.7; 95% confidence interval (CI) 1.2-11.1; p = 0.018). Multivariable logistic regression adjusted for age at ART initiation, gender, pre-ART CD4 count, months on ART, and tuberculosis history indicated higher odds of retention in adolescents and young adults attending adolescent compared to standard clinic (AOR = 8.5; 95% CI 2.3-32.4; p = 0.002). Viral suppression was higher among adolescents and young adults attending adolescent (91%) versus standard pediatric clinic (80%; OR 2.5; 95% CI 1.1-5.8; p = 0.028). A similar multivariable logistic regression model indicated higher odds of viral suppression in adolescents and young adults attending adolescent versus standard pediatric clinic (AOR = 3.8; 95% CI 1.5-9.7; p = 0.005). CONCLUSION: Adolescents and young adults attending an adolescent-friendly clinic had higher retention in care and viral suppression compared to adolescents attending the standard pediatric clinic. Further studies are needed to prospectively assess the impact of adolescent-friendly services on these outcomes.

PURPOSE OF REVIEW: This review describes recent literature on novel ways technology is used for assessment of illicit drug use and HIV risk behaviours, suggestions for optimizing intervention acceptability, and recently completed and ongoing technology-based interventions for drug-using persons at risk for HIV and others with high rates of drug use and HIV risk behaviour. RECENT FINDINGS: Among studies (nâ=â5) comparing technology-based to traditional assessment methods, those using Ecological Momentary Assessment (EMA) had high rates of reported drug use and high concordance with traditional assessment methods. The two recent studies assessing the acceptability of mHealth approaches overall demonstrate high interest in these approaches. Current or in-progress technology-based interventions (nâ=â8) are delivered using mobile apps (nâ=â5), text messaging (nâ=â2) and computers (nâ=â1). Most intervention studies are in progress or do not report intervention outcomes; the results from one efficacy trial showed significantly higher HIV testing rates among persons in need of drug treatment. SUMMARY: Studies are needed to continually assess technology adoption and intervention preferences among drug-using populations to ensure that interventions are appropriately matched to users. Large-scale technology-based intervention trials to assess the efficacy of these approaches, as well as the impact of individual intervention components, on drug use and other high-risk behaviours are recommended.

Zika virus has recently been introduced to the Americas and is spreading rapidly. We evaluated the characteristics of US travelers to Zika virus-affected countries who were seen at Global TravEpiNet sites during March 2015-October 2016. Nearly three quarters of travelers were men or women of reproductive age.

BACKGROUND: International travellers are at risk of travel-related, vaccine-preventable diseases. More data are needed on the proportion of travellers who refuse vaccines during a pre-travel health consultation and their reasons for refusing vaccines. METHODS: We analyzed data on travellers seen for a pre-travel health consultation from July 2012 through June 2014 in the Global TravEpiNet (GTEN) consortium. Providers were required to indicate one of three reasons for a traveller refusing a recommended vaccine: (1) cost concerns, (2) safety concerns or (3) not concerned with the illness. We calculated refusal rates among travellers eligible for each vaccine based on CDC recommendations current at the time of travel. We used multivariable logistic regression models to examine the effect of individual variables on the likelihood of accepting all recommended vaccines. RESULTS: Of 24 478 travellers, 23 768 (97%) were eligible for at least one vaccine. Travellers were most frequently eligible for typhoid (N = 20 092), hepatitis A (N = 12 990) and influenza vaccines (N = 10 539). Of 23 768 eligible travellers, 6573 (25%) refused one or more recommended vaccine(s). Of those eligible, more than one-third refused the following vaccines: meningococcal: 2232 (44%) of 5029; rabies: 1155 (44%) of 2650; Japanese encephalitis: 761 (41%) of 1846; and influenza: 3527 (33%) of 10 539. The most common reason for declining vaccines was that the traveller was not concerned about the illness. In multivariable analysis, travellers visiting friends and relatives (VFR) in low or medium human development countries were less likely to accept all recommended vaccines, compared with non-VFR travellers (OR = 0.74 (0.59-0.95)). CONCLUSIONS: Travellers who sought pre-travel health care refused recommended vaccines at varying rates. A lack of concern about the associated illness was the most commonly cited reason for all refused vaccines. Our data suggest more effective education about disease risk is needed for international travellers, even those who seek pre-travel advice.

UNLABELLED: Patients with prior virologic failure (VF) are at an increased risk of subsequent failure, emergence of resistance, and death. This analysis identifies outcomes and correlates of VF in a high-risk population. METHODS: A5251 was designed to evaluate an enhanced adherence counseling intervention delivered by nurses from a central call site on virologic suppression. Due to slow enrollment, the study was closed prematurely and revised study endpoints were evaluated (week 24 VF (HIV-1 RNA ≥200 copies/ml) and non-perfect adherence (<100% self-reported using both the ACTG adherence questionnaire and visual analog scale (VAS)). RESULTS: Fifty-nine participants were enrolled, 43 (73%) black non-Hispanic and 23 (39%) women. Median prior antiretroviral regimen changes were three and the co-morbidity in this population was higher than typical for HIV clinical trials. At week 24 (n = 41), 24 (59%) failed to reach virologic suppression (HIV-1 RNA <200 copies/ml) and 25 (63%) reported non-perfect adherence. Higher depression (CES-D10) and adverse illness perceptions (IPQ-B) were associated with week 24 non-adherence. Early clinical assessments (week 12 HIV-RNA ≥200 copies/mL and non-perfect adherence) as well as higher depression and adverse illness perceptions were associated with week 24 VF. DISCUSSION: In this high-risk population, the proportion of participants with suboptimal adherence and VF was unacceptably high. Interventions to address this treatment gap are clearly needed. Depression and a higher illness perception score, failure to achieve virologic suppression by week 12, and less than perfect adherence could be used to target individuals for early interventions in treatment-experienced, high-risk individuals at high risk for VF.

BACKGROUND: Effective and easy to implement interventions to improve adherence to antiretroviral therapy are needed. OBJECTIVE: To compare site nurse-initiated adherence and symptom support telephone calls for HIV-positive individuals starting antiretroviral therapy to the study site's standard of care. METHODS: A randomized controlled trial of site nurse-initiated adherence and symptom support telephone calls for HIV-positive individuals starting antiretroviral therapy. Subjects were randomized to receive site nurse-initiated telephone calls (intervention) or no additional calls to the site's standard of care (control). Subjects received calls 1 to 3 days after initiating antiretrovirals, on weeks 1, 2, 3, 6, 10, 14, 18, 22, and 26, and every 8 weeks thereafter. Self-reported adherence was captured during study visits. RESULTS: A total of 333 subjects starting antiretrovirals as part of ACTG 384 were co-enrolled into ACTG 5031. Subjects were followed for up to 160 weeks and were contacted for 74% of scheduled calls. There was no significant difference in proportion of patients with â¯95% mean total adherence (87.9% and 91.2%; P = .34) and mean self-reported total adherence (97.9% and 98.4%) in the intervention and control groups, respectively, or in symptom distress and clinical endpoints. CONCLUSIONS: In the context of a clinical trial where self-reported adherence was exceptionally high, the site nurse-initiated telephone calls did not further improve self-reported adherence, symptom distress, or clinical outcomes.

BACKGROUND: Data to support improved patient outcomes from clinical decision-support systems (CDSSs) are lacking in HIV care. OBJECTIVE: To test the efficacy of a CDSS in improving HIV outcomes in an outpatient clinic. DESIGN: Randomized, controlled trial. (ClinicalTrials.gov registration number: NCT00678600) SETTING: Massachusetts General Hospital HIV Clinic. PARTICIPANTS: HIV care providers and their patients. INTERVENTION: Computer alerts were generated for virologic failure (HIV RNA level >400 copies/mL after a previous HIV RNA level ≤400 copies/mL), evidence of suboptimal follow-up, and 11 abnormal laboratory test results. Providers received interactive computer alerts, facilitating appointment rescheduling and repeated laboratory testing, for half of their patients and static alerts for the other half. MEASUREMENTS: The primary end point was change in CD4 cell count. Other end points included time to clinical event, 6-month suboptimal follow-up, and severe laboratory toxicity. RESULTS: Thirty-three HIV care providers followed 1011 patients with HIV. In the intervention group, the mean increase in CD4 cell count was greater (0.0053 vs. 0.0032 × 109 cells/L per month; difference, 0.0021 × 109 cells/L per month [95% CI, 0.0001 to 0.004]; P = 0.040) and the rate of 6-month suboptimal follow-up was lower (20.6 vs. 30.1 events per 100 patient-years; P = 0.022) than those in the control group. Median time to next scheduled appointment was shorter in the intervention group than in the control group after a suboptimal follow-up alert (1.71 vs. 3.48 months; P < 0.001) and after a toxicity alert (2.79 vs. >6 months; P = 0.072). More than 90% of providers supported adopting the CDSS as part of standard care. LIMITATION: This was a 1-year informatics study conducted at a single hospital subspecialty clinic. CONCLUSION: A CDSS using interactive provider alerts improved CD4 cell counts and clinic follow-up for patients with HIV. Wider implementation of such systems can provide important clinical benefits.
