MedicalResearch.com Interview with: [caption id="attachment_46749" align="alignleft" width="159"]Richard Miech Ph.D Professor Principal Investigator, Monitoring the Future Institute for Social Research University of Michigan Dr. Miech[/caption] Richard Miech Ph.D Professor Principal Investigator, Monitoring the Future Institute for Social Research University of Michigan MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Every year Monitoring the Future conducts a survey to examine trends in adolescent substance use.  We draw a random sample of schools from a list of all schools in the United States and conduct our survey in ~400 schools.  Our survey is representative of U.S. 8th, 10th, and 12th grade students.  In other words, our results are what you would find if you surveyed every single 8th, 10th, and 12th graders in the United States, within the bounds of a small sampling error of a few percentage points. An increase in vaping is the big news for 2018.  In 10th and 12th grade the increase in nicotine vaping was the largest we've ever seen for any substance in the past 43 years.  As a result of this increase in nicotine vaping, overall use of nicotine increased as well, which suggests that vaping is drawing youth into nicotine use.  We also saw a significant increase in marijuana vaping.

What are the main findings? Response: ​For this study we analyzed data that were collected as part of a larger survey study that recruited a sample of adolescents who were coming to the doctor's office for routine medical care.  We asked them a lot of questions about their health, school, extracurricular activities, plans for the future, substance use patterns and problems associated with use among other things. The main finding was that among the participants who reported marijuana use in the past year, many of them, more than 40%, said that they had experienced either an hallucination, or paranoia/anxiety related to their use. Kids who used more frequently and those who met criteria for a substance use disorder were more likely to experience these symptoms, as were those who had symptoms of depression

What are the main findings? Response: Previous research has found some troubling relations between adolescent cannabis use and subsequent increases in conduct problems and other unhealthy consequences.  These studies were done in New Zealand in the late 90’s and we wanted to re-examine those relationships using more contemporary data in the US. We had data on 364 adolescents who were followed from age 13 to 19 in Philadelphia that could provide a more up to date picture of the effects of using cannabis on one important outcome, conduct disorder.  We also wanted to use more sensitive methods than had been used in prior research that would enable us to examine reciprocal relations between cannabis use and c (CP).  That is, it might be the case that youth with CP are prone to using cannabis and that this helps to explain why there appears to be a relation over time between cannabis use and CP rather than cannabis use leading to CP. Our findings supported that hypothesis.  There was no prospective relation between changes in cannabis use and subsequent changes in conduct problems.  Instead, changes in conduct problems were found to predict changes in use of cannabis.  Youth with conduct problems also affiliated more with peers who used cannabis, adding further to their own use.  There was also no evidence that youth who used cannabis sought out peers who used it apart from the effects of CP. Finally, both use of cannabis and  conduct problems predicted subsequent development of a mild cannabis use disorder (CUD).

MedicalResearch.com Interview with: “Me holding USP gun” by Nghị Trần is licensed under CC BY 2.0Faiz Gani, PhD Postdoctoral research fellow Department of Surgery Johns Hopkins University School of Medicine MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Firearm related injuries are a leading cause of injury and death in the United States, yet, due to combination of factors, limited data exist that evaluate these injuries, particularly among younger patients (patients younger than 18 years). The objective of this study was to describe emergency department utilization for firearm related injuries and to quantitate the financial burden associated with these injuries. In our study of over 75,000 emergency department visits, we observed that each year, over 8,300 children and adolescents present to the emergency department for the treatment / management of a gunshot injury. Within this sub-population of patients, we observed that these injuries are most frequent among patients aged 15-17 years and while these injuries decreased over time initially, were observed to increase again towards the end of the time period studied. In addition to describing the clinical burden of these injuries, we also sought to describe the financial burden associated with these injuries. For patients discharged from the emergency department, the average (median) charge associated with their care was $2,445, while for patients admitted as inpatients for further care, the average (median) charge was $44,966. Collectively these injuries resulted in $2.5 billion in emergency department and hospital charges over the time period studied. This translates to an annual financial burden of approximately $270 million.

What are the main findings? Response: We wanted to look at reasons parents don’t vaccinate their children against HPV, including how those reasons have changed over time from 2010-2016 and how those reasons are different between boys and girls in the most recent data from 2016. We used a nationwide dataset which is publically available from the CDC (Centers for Disease Control) – the National Immunization Survey-Teen, or NIS-Teen - which surveys parents of teens ages 13-17 years old every year to determine rates of all recommended vaccinations. In parents who report that they don’t intend to vaccinate their child against HPV , the survey asks parents why. We found that from 2010 to 2016, the percentage of parents reporting concerns about their child not being sexually active yet went down significantly for both boys and girls. Also, in boys specifically, parents reported male gender as a less common reason for not vaccinating. For both boys and girls, we found that concerns about safety and side effects, necessity, and lack of knowledge about the vaccine were common reasons for not planning to vaccinate.  Also, 10% of parents of girls vs. 20% of parents of boys reporting never having a provider recommendation for the vaccine as their primary reason for not vaccinating. These results may reflect the growing public understanding of the HPV vaccine as a vaccine which is best given before exposure, so before initiation of sexual activity between the ages of 11 and 12, and that it is recommended for both boys and girls. Also, over 80% of people will have an HPV infection in their lifetime, so everyone should get vaccinated regardless of anticipated sexual activity. Additionally, providers should focus their counseling and recommendation on improving knowledge about the HPV vaccine, including its decade-long track record of safety and necessity.

MedicalResearch.com Interview with: Joshua Barocas, MD Assistant Professor of Medicine Section of Infectious Diseases Boston Medical Center / Boston University School of Medicine Joshua Barocas, MD Assistant Professor of Medicine Section of Infectious Diseases Boston Medical Center / Boston University School of Medicine  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Massachusetts has been particularly hard hit by the opioid epidemic despite lower opioid prescribing rates, near universal health insurance, and availability of opioid treatment. That said, it is difficult to estimate the population with or at-risk for opioid use disorder. It is generally a highly stigmatized disease and typical methods to estimate of opioid use disorder relay on contact with the healthcare system and/or patient reporting. We used a unique and powerful methodology coupled with a first-in-the-nation linked database in Massachusetts to obtain both an accurate count of people with opioid use disorder who are known to the healthcare system and estimate the number who are out there but not yet known to the system. We found that more than 275,000 people – or 4.6 percent of people over the age of 11 in Massachusetts– have opioid use disorder, a figure nearly four times higher than previous estimates based on national data. In 2011 and 2012, the prevalence of opioid use disorder in Massachusetts for those over the age of 11 was 2.72 percent and 2.87 percent, respectively. That increased to 3.87 percent in 2013, and even more, to 4.6 percent in 2015. Those between the ages of 11 and 25 experienced the greatest increase in prevalence of all age groups. The number of “known” persons increased throughout the study period – from 63,989 in 2011 to 75,431 in 2012, and 93,878 in 2013 to 119,160 in 2015.

MedicalResearch.com Interview with: "Electronic Cigarette/E-Cigs/E-Cigarettes" by Chris F is licensed under CC BY 2.0Brian King, PhD Lead author and Deputy Director for Research Translation Office on Smoking and Health. CDC MedicalResearch.com: What is the background for this study? Response: Since first entering the U.S. marketplace in 2007, e-cigarettes have been a rapidly evolving product class. Typically, national surveys provide annual, self-reported estimates of e-cigarette use among adults and youth. However, given the dynamic nature of the e-cigarettes landscape, data collected at a sub-annual level can be useful for identifying rapid changes and patterns. For example, retail sales data, which is available at more frequent intervals, such as weekly, can complement annual surveys and help keep a pulse on emerging trends. This study assessed e-cigarette retail sales data in the United States from 2013 through 2017.

MedicalResearch.com Interview with: [caption id="attachment_44480" align="alignleft" width="132"]Katrina Trivers, PhD, MSP Lead author and lead epidemiologist Office on Smoking and Health CDC Dr. Trivers[/caption] Katrina Trivers, PhD, MSP Lead author and lead epidemiologist Office on Smoking and Health CDC MedicalResearch.com: What is the background for this study? Response: Although we’ve seen considerable declines in the use of regular cigarettes among U.S. youth over the past several decades, the tobacco product landscape is evolving, and the use of other tobacco products have become increasingly popular. For example, as of 2014, e-cigarettes have become the most commonly used tobacco product among US youth. During 2011-2015, e-cigarette use increased 900% among U.S. high school students before declining in 2016. No change was observed in 2017, with about 2 million youth, including 12% of high school students and 3% of middle school students, reporting they had used e-cigarettes in the past 30 days. This is a public health concern because the use of any form of tobacco product is unsafe among youth, irrespective of whether it’s smoked, smokeless, or electronic. The U.S. Surgeon General has concluded that the aerosol emitted from e-cigarettes is not harmless. It can contain harmful ingredients, including nicotine, carbonyl compounds, and volatile organic compounds known to have adverse health effects. The nicotine in these products is of particular concern given that nicotine exposure during adolescence can cause addiction and can harm the developing adolescent brain. In recent years, many youth have also been using other psychoactive substances in e-cigarettes, including cannabinoids and other illicit drugs. This could have been fueled, in part, by shifts in the social acceptability and access to cannabis as several states have or are considering legalized cannabis sales for adults. A previous CDC study found that in 2015, almost 1 in 3 students reported using e-cigarettes with non-nicotine substances. However, it wasn’t possible to identify what exactly those substances were based on the question. Given the high concurrent use of tobacco and other substances, including cannabis, a more detailed question was added to a future survey to assess the use of cannabis in e-cigarettes among U.S. youth. This study presents the findings from that question.

Response: Amidst a worsening overdose epidemic in the United States, adolescents and young adults have not been spared. Although evidence-based medications like buprenorphine, naltrexone, and methadone are recommended for adolescents and young adults, the extent to which youth receive these medications — and whether these medications help retain youth in addiction treatment — isn’t yet known.

What are the main findings? Response: Homicide is the third leading cause of death among adolescents, and disproportionately affects minority youth in under-resourced urban communities. Most research on youth violence focuses on risk factors, such as weapon carrying and substance abuse. We know much less about factors that protect youth from violence. Future orientation, defined as hopes and plans for the future, is linked to many important positive outcomes for youth, including doing well in school and avoiding illicit substances. However, there has been very little research to examine whether future orientation may also protect youth from violence. To study links between future orientation and violence perpetration, we surveyed over 850 male youth in lower resource neighborhoods in Pittsburgh as part of a community-based sexual violence prevention study. We found that youth with positive future orientation were significantly less likely to report threatening someone with a weapon or injuring someone with a weapon in the past nine months.

Would you briefly explain what is meant by JUUL?  Response: The JUUL vaporizer is the latest advancement in electronic cigarette technology, delivering nicotine to the user from a device about the size and shape of a thumb drive. JUUL has taken the electronic cigarette market by storm experiencing a year-over-year growth of about 700 percent. In our most recent study, we wanted to document and describe the public’s initial experiences with JUUL. We collected posts to Twitter containing the term “Juul” from April 1, 2017 to December 14, 2017. We analyzed over 80,000 posts representing tweets from 52,098 unique users during this period and used text classifiers (automated processes that find specified words and phrases) to identify topics in posts.

Response: Buprenorphine is a prescription opioid medication commonly used to treat opioid use disorder. From 2005 to 2010, the annual number of individual patients who received a buprenorphine prescription increased from 100,000 to more than 800,000. Although buprenorphine is important for the treatment of opioid use disorder, pediatric exposure to this medication can result in serious adverse outcomes.

MedicalResearch.com Interview with: Randall C. Swaim, Ph.D. Senior Research Scientist and Director Linda R. Stanley, Ph.D. Senior Research Scientist Tri-Ethnic Center for Prevention Research Department of Psychology Colorado State University                           MedicalResearch.com: What is the background for this study? Response: American Indian adolescents consistently report the highest levels of substance use compared with other US racial/ethnic groups. The harm associated with these high rates of use include higher risk of developing a substance use disorder, more alcohol-related problems, including alcohol-attributable death, and other negative outcomes such as school failure. These findings point to the importance of continuing to monitor this group, particularly given changing trends in perceived harmfulness of illicit substances as new statutes alter access to medical and recreational use of cannabis.

Response: There has not been a comprehensive review of how allergic rhinitis impacts the adolescent population. Most studies put adolescents in with children and yet we know that how disease affects adolescents may be dramatically different than children. Adolescents is a difficult enough time with a chronic condition MedicalResearch.com: What is the key take-home message? Response: The symptoms associated with nasal and eye allergies can be different in adolescents compared with adults and children and lead to poor quality of life and impair learning in school. Adolescents with AR/ARC may experience difficulties falling asleep, night waking, and snoring, and generally have poorer sleep. Therefore health care providers need to aggressively control the adolescent’s allergic rhinitis.

MedicalResearch.com Interview with: Natalie Castellanos Ryan, PhD École de Psychoéducation Université de Montréal Outremont Canada  MedicalResearch.com: What is the background for this study? Response: Our study followed a group of boys living in low socioeconomic neighbourhoods in Montreal (N=1030) from early childhood to 28 years of age to investigate: 1) whether the age at which one starts to use cannabis across adolescence is associated with the risk of developing drug abuse by early adulthood, when one controls for  arrange of known risk factors for cannabis use and problems assessed across development (risk factors in childhood, adolescence and early adulthood); and 2) the developmental pathways from early risk factors to drug abuse problems. To examine these associations, the study collected  self-reported cannabis use information from these boys annually from ages 13 to 17 years and drug abuse symptoms at 28 years, as well as teacher, parent and child reported information on a number of environmental (family and friend) and child characteristics (e.g., impulsivity, delinquency, school performance) across childhood and adolescence. Alcohol and other drug use was also assessed across adolescence and early adulthood.

What are the main findings? Response: We have been studying the steady increase in gun violence that has been occurring in popular PG-13 movies since the new rating was adopted in 1984.  It has recently even surpassed the amount of gun violence in R-rated movies.  Since these movies are open to the public at any age, we are concerned that they promote the use of guns and potentially socialize youth to believe that using guns to defend oneself is an appropriate way to handle threats and other conflicts. We knew that the rating requires the omission of graphic consequences, such as blood and suffering, that can make the violence more acceptable.  But we also wondered whether the motivation for the violence might make a difference as well.  Many of the characters in PG-13 movies are seen as heroic (e.g., Bruce Willis and Liam Neeson).  Could that also be a factor that makes such films more acceptable to parents despite their concerns about their children seeing so much violence in the movies.  So, we conducted this experiment to see if parents are less upset by justified violence in PG-13 style movies.

What are the main findings? Response: 2-3% of adolescents have idiopathic scoliosis and 1 in 10 of these individuals will require surgery to correct severe scoliosis which if left untreated can lead to back pain and disability as well as pulmonary (breathing) problems later in life. For the adolescent with curvatures that require surgical treatment, body image and self esteem are big issues as they are for all adolescents going through their developmental stages. Scoliosis has an impact on body shape, which is seen by the affected individual looking in the mirror as well as by their peers and those around them. This can lead to self esteem and body image disturbance issues. We set out to explore the body shape distortions that occur with scoliosis, that are not depicted by x-rays that are standardly used to assess curvatures of the spine, and the improvements in parameters of body shape that occur with corrective surgery. We can assess body shape directly through surface topography imaging, that is light-based, thus, not involving x-ray exposure. This technology (Diers Formetrics) uses the same scientific methodology that is used to create modern topographical maps through satellite imagery. We found dramatic improvements in body shape asymmetry with surgery that correlated with some improvements in quality of life for the adolescent in this cohort of 23 patients as well as with the improvements in curvatures evaluated by x-rays.

MedicalResearch.com Interview with: “medical marijuana : strains and varieties” by torbakhopper is licensed under CC BY 2.0Professor Deborah Hasin PhD Department of Epidemiology in Psychiatry Mailman School of Public Health Columbia University MedicalResearch.com: What is the background for this study? What are the main findings? Response: We began to think about this study after we published an earlier report (Hasin et al., The Lancet Psychiatry 2015) showing that after state medical marijuana laws (MML) were passed, U.S. teen marijuana use did not increase compared to the period before the laws were passed and to overall national trends. However, people continued to question whether MML led to teen increases in marijuana use. Therefore, in the present study, we combined findings from 11 large-scale national studies of teens to provide a more definite answer. The findings were clear that teen marijuana use did not increase after passage of medical marijuana laws. Medical marijuana is widely available from stores like kush guys, yet despite this prevalence, there is no conclusive evidence of abuse. Rather the benefits are plain to see.

Wheaton, Ph.D. Epidemiologist Centers for Disease Control and Prevention National Center for Chronic Disease Prevention and Health Promotion Division of Population Health Epidemiology and Surveillance Branch Atlanta, GA  30341-3717 MedicalResearch.com: What is the background for this study? Response: Insufficient sleep among children and adolescents is associated with an increased risk for obesity, diabetes, injuries, poor mental health, and attention and behavior problems. In previous reports, CDC had found that, nationwide, approximately two thirds of U.S. high school students report sleeping <8 hours per night on school nights. CDC conducted this study to provide state-level estimates of short sleep duration on school nights among middle school and high school students using age-specific recommendations from the American Academy of Sleep Medicine (AASM). AASM has recommended that children aged 6–12 years should regularly sleep 9–12 hours per 24 hours and teenagers aged 13–18 years should sleep 8–10 hours per 24 hours for optimal health.

Our findings suggest an important association between the use of social media and short sleep duration among student aged 11-20 years. Using social media for at least one hour per day was associated with short sleep duration in a dose-response manner.

What are the main findings? Response: Monitoring the Future conducts annual, nationally-representative surveys of ~45,000 adolescents every year to assess trends in substance use. We track which drugs are gaining traction among adolescents and which are falling out of favor. The survey draws separate, nationally-representative samples of 8th, 10th, and 12th grade students from about 400 total schools every year. Once a recruited school agrees to participate, a field interviewer travels to the school to administer the paper-and-pencil survey, typically in classrooms. The project is funded by the National Institute of Drug Abuse and is carried out by the University of Michigan. More details on the project's survey design and survey procedures can be found in chapter 3 here: http://monitoringthefutu re.org/pubs/monographs/mtf- vol1_2016.pdf

Adams, PhD, RN Specialist, Division of Adolescent and Young Adult  Medicine Adolescent and Young Adult Health National Resource Center University of California, San Francisco Benioff Children’s Hospital San Francisco, CA 94118 MedicalResearch.com: What is the background for this study? Response: Major causes of adolescent illness and mortality are preventable. To address this, in the 1990s, professional medical organizations developed healthcare provider guidelines for the delivery of adolescent preventive healthcare. These include the receipt of anticipatory guidance and risk screening services in the effort to promote healthy behaviors and avoid risky behaviors that are intended to be covered within a preventive care visit, but could be addressed in other healthcare visits. The adolescent developmental period is an important time for adolescents to be engaged with the healthcare system. Transitioning from childhood to adulthood, adolescents are becoming increasingly independent - having more responsibility and freedom for decision making in many areas, including healthy choices in behaviors and activities. While families and community settings (schools, churches) play strong roles in this process, the healthcare system also plays an important role.

MedicalResearch.com Interview with: M. Loredana Marcovecchio, M.D. Clinical Scientist and Professor David Dunger M.D. Director of Research Professor of Paediatrics University of Cambridge MedicalResearch.com: What is the background for this study? What are the main findings? Response: The efficacy and safety of ACE Inhibitors and statins in adolescents have been shown in the context of hypertension and familial hypercholesterolemia, respectively. However, there is a lack of data on the long-term use of these drugs in those with type 1 diabetes and, in particular, there is no clear indication for their use in patients with increased albumin excretion. The Adolescent type 1 Diabetes cardio-renal Intervention Trial (AdDIT) was a multi-centre, international study, set up by investigators in the UK, Australia and Canada to explore if drugs already used to lower blood pressure (ACE inhibitors) and cholesterol levels (Statins) in adults with diabetes could reduce the risk of kidney, eye and cardiovascular disease in adolescents with Type 1 diabetes. Neither ACE inhibitors nor statins significantly reduced the albumin-creatinine ratio during the 2-4 year trial period. However, some of the secondary outcomes suggest that the drugs may have important benefits. Treatment with the ACE inhibitor resulted in a 43% reduction in the rates of progression to microalbuminuria, which was not statistically significant, but it could have important clinical implications. Preventing even intermittent cases of microalbuminuria is known to reduce the future risk of kidney and cardiovascular complications. Statin therapy led to reduced levels of lipid levels, which could reduce long-term risk for cardiovascular complications. These findings could translate into long-term benefits, but follow-up of this unique cohort will be essential. The essential biological samples and data provided by the participants will continue to inform our future understanding and our options for effective therapies for this vulnerable group of young people with type 1 diabetes.

Rasberry, PhD Health Scientist, Division of Adolescent and School Health CDC Atlanta MedicalResearch.com: What is the background for this study? What are the main findings? Response: For many years, researchers have documented links between health-related behaviors and educational outcomes such as letter grades, test scores, and other measures of academic achievement. However, many of those studies are becoming out-of-date or have used samples that were not nationally representative. The aim of this study was to see if previous findings held in a current, national sample of high school students. Consistent with previous studies, our findings revealed that regardless of sex, race/ethnicity and grade-level, high school students who received mostly A’s, mostly B’s, or mostly C’s had higher levels of most protective health-related behaviors and lower levels of most health-related risk behaviors. For example, we found that:
  • Students who reported receiving mostly Ds and Fs, were nine times more likely than students who received mostly As to report having ever injected any illegal drugs.
  • Also, students who reported receiving mostly Ds and Fs were more than four times more likely than students who received mostly As to report that they had four or more sexual partners.
  • Conversely, students who reported receiving mostly As were twice as likely as students who received mostly Ds and Fs to report eating breakfast every day in the past week.

MedicalResearch.com Interview with: [caption id="attachment_36623" align="alignleft" width="200"]Dan Romer PhD Research director, Annenberg Public Policy Center Director of its Adolescent Communication Institute University of Pennsylvania Dr. Dan Romer[/caption] Dan Romer PhD Research director, Annenberg Public Policy Center Director of its Adolescent Communication Institute University of Pennsylvania MedicalResearch.com: What is the background for this study? Response: In recent years, findings from research in developmental neuroscience indicate that the myelination of the prefrontal cortex (PFC) extends into the third decade of life, proceeding more slowly than in other brain regions. Because subcortical and sensory brain regions appear to mature earlier, this and other findings have been taken as evidence that adolescents may have less ability to control their behavior than children do. These findings spawned theories of “imbalanced” adolescent brain development that were proposed to explain heightened vulnerability to risky behavior and adverse health outcomes during adolescence. Although there is little doubt that as adolescents enter adulthood, they are at risk for many health outcomes that can accompany the initiation of such behaviors as driving, having sex, using drugs, and playing sports. But most adolescents make it through this period of development without serious health consequences. Thus, the argument that a brain deficit is responsible for such adverse health outcomes seemed to overgeneralize effects that only occur for a minority of adolescents. Furthermore, when my colleagues and I examined the evidence in support of imbalance theories, we found it unconvincing. Indeed, it seemed that findings from neuroscience were interpreted through the lens of stereotypes about adolescents that conflate exploration with impulsivity. That is, many of the risky behaviors that attract adolescents are novel activities that reflect lack of experience rather than lack of control over behavior.

MedicalResearch.com Interview with: [caption id="attachment_36583" align="alignleft" width="180"]Galit Dunietz, Ph.D., MPH Doctor of Philosophy Department of Neurology University of Michigan  Ann Arbor MI Dr. Dunietz[/caption] Galit Dunietz, Ph.D., MPH Epidemiologist, Sleep Disorders Center Department of Neurology University of Michigan Ann Arbor MI MedicalResearch.com: What is the background for this study? What are the main findings? Response: Insufficient sleep has a negative impact on health, cognition and mood and is linked to motor vehicle accidents. However, sleep loss in adolescents has become an epidemic and arises in part from biological processes that delay sleep and wake timing at the onset of puberty. This biology does not fit well with early school start times (before 8:30 a.m.). Despite recommendations from the American Academy of Pediatrics and the American Academy of Sleep Medicine to delay school start times, most schools in the U.S. have current start times before 8:30 a.m. In this nationally representative study of US parents of teens, we examined whether parents supported or opposed later school start times (after 8:30 a.m.). We also examined what may have influenced their opinions. We found that only about half of surveyed parents of teens with early school start times supported later school start times. Opinions appeared to depend in part on what challenges and benefits were expected to result from the change. For example, parents who expected an improvement in their teen’s academic performance or sleep quantity tended to support the change, whereas parents that expected negative impact on afterschool activities or transportation opposed delays in school start times.  We also found that parents had misconception about sleep needs of their adolescents, as the majority perceived 7-7.5 hours of sleep as sufficient, or possibly sufficient even at this young age when 8-10 hours are typically recommended.

Cope MD Medical Officer Division of Foodborne, Waterborne, and Environmental Diseases National Center for Emerging and Zoonotic Infectious Diseases CDC MedicalResearch.com: What is the background for this study? What are the main findings? Response: Wearing contact lenses can increase your chances of getting a severe eye infection. Eye infections can lead to serious problems, including blindness. All contact lens wearers can help prevent serious eye infections by correctly wearing and caring for their contact lenses. Eighty-one percent of young adults, 85% of adolescents, and 88% of older adults regularly did at least one risky behavior related to their contact lenses. The most frequently reported risk behaviors in adolescents were not visiting an eye doctor as least annually, sleeping or napping in lenses, and swimming in lenses. Among young adults and older adults, the most frequently reported risk behaviors were replacing lenses at intervals longer than those prescribed, replacing lens storage cases at intervals longer than those recommended, swimming in lenses, and sleeping or napping in lenses.

Response: Dr Stephanie Chiuve and colleagues at the Harvard TH Chan School of Public Health developed the Healthy Heart Score to predict the risk of heart disease in older adults based on lifestyle factors measured in middle age. We have known for some time that the precursor to heart disease – known as atherosclerosis – actually starts in childhood and adolescence. We calculated the Healthy Heart Score for young adults ages 18-30 years old and found it works in this age group as well.

What are the main findings? Response: Oregon legalized sale and use of marijuana for recreational purposes and the part of the law (regarding use) took effect in July 2015. However, there have been no controlled studies of which we’re aware of the possible effects of the Oregon law that take into account the trends toward increased marijuana use across the country and differences in use rates between states that predated the law. We used survey data on college students in Oregon and in 6 states without recreational legalization to examine the issue.
