MedicalResearch.com: What is the background for this study?
Response: It has been well known that sexual minority adults in the US have worse health as compared with heterosexual peers. Queer folks are found to have poorer physical, mental and behavioral health outcomes because of their marginalized status and social environments. But we know very little about prevalence of sleep problems in the population of sexual minorities compared to heterosexual people. Do sexual minorities lose sleep? Do they wake up more often during the night? Do they sleep less? This study aims to address this important gap in the LGBT health literature. Using recent nationally representative data, we exam whether sexual minority adults have greater odds of having short sleep duration and poor sleep quality. In addition, we also investigate sexual minorities’ sleep in the context of gender and race/ethnicity

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: The aging of the baby boomer population is focusing attention on the health experience of this sector of the population. Arthritis is one of the most frequent chronic health problems in the population. Our research question was to investigate whether the prevalence of arthritis differs between generations (also called birth cohorts) and what might be associated with any differences. Using data collected in a longitudinal Canadian population health survey between 1994 and 2011, we looked at 4 generations: the World War II generation born 1935-1944, older baby boomers born 1945-1954, younger baby boomers born 1955-64, and Generation X born 1965-1974.

MedicalResearch.com: What is the background for this study?
Response: Stevens-Johnson syndrome and Toxic Epidermal Necrolysis (SJS/TEN) are relatively rare and potentially life-threatening disorders. There have been some recent advances in our understanding of the epidemiology and risk factors of SJS/TEN in adults.
However, little is known about the epidemiology of pediatric SJS/TEN.
26 Mar Psoriasis Patients At Higher Risk for Multiple Pathological Fractures
MedicalResearch.com Interview with: Dr. Jonathan L. Silverberg MD PhD MPH Assistant Professor in Dermatology Medical Social Sciences and Preventive Medicine Northwestern University, Chicago, Illinois [caption id="attachment_24142" align="alignleft" width="128"] Dr. Jonathan Silverberg[/caption]
Response: Psoriasis is associated with a number of potential risk factors for developing osteoporosis and pathological fractures, including including low vitamin D, chronic inflammation, higher rates of cigarette smoking and systemic corticosteroid usage. We hypothesized that adults with psoriasis have higher rates of osteoporosis and pathological fractures.
We examined data from the 2002-2012 National Inpatient Sample, which contains a representative 20% sample of all hospitalizations in the United States. We found that psoriasis was associated with higher odds of osteopenia, osteoporosis, osteomalacia, ankylosing spondylitis, and pathological fractures. In particular, psoriasis was associated with vertebral, pelvic, femoral and tibial/fibular fractures. The associations between psoriasis and pathological fractures were more pronounced in women than men.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Atopic dermatitis (AD) is associated with considerable morbidity and quality of life impairment. AD patients may require hospitalization for acute treatment of serious flares and/or inadequately controlled chronic disease.
We examined data from the 2002-2012 National Inpatient Sample, which contains a representative 20% sample of all hospitalizations in the United States. We found that there were substantial numbers of children and adults hospitalized in the United States for AD. Hospitalization rates for atopic dermatitis were highest in the northeast during the winter likely due to cold and dry weather and south during the summer likely due to heat and humidity. Further, hospitalization rates for AD significantly increased in adults between 2002 and 2012. The costs per individual hospitalization were lower in children and adults with AD compared to those without atopic dermatitis. However, the high prevalence of hospitalization resulted in total inpatient costs of >$8 and >$3 million per-year for adults and children, respectively.
25 Mar Home Health Care Providers Increase, But Geographic Variability Persists
MedicalResearch.com Interview with: Sheila Eckenrode RN, CPHQ Quality Improvement Consultant The New England QIN-QIO Qualidigm, Wethersfield, Connecticut MedicalResearch.com: What is the background for this study? Response: Post-acute care has become a focus for improving quality and cost effectiveness of healthcare in the United States. Changes in Medicare payment systems such as bundled payments and the emergence of Affordable Healthcare Organizations will most likely lead to expansion of post-acute care services and decrease in acute care hospitalizations. Approximately 30% of hospitalized Medicare beneficiaries were referred to home health care at discharge in 2012. In 2013, home health agencies served 3.5 million beneficiaries with Medicare paying $18 billion for these services. Home health care has been emphasized under the Improving Medicare Post-Acute Care Transformation Act of 2014 to provide and improve care at individual patient and community levels. In anticipation of increasing utilization of home care services, our study aimed to demonstrate the overall growth in home care availability as well as identify geographical variation and potential gaps in service.24 Mar Youth With Autism Use Emergency Rooms At Markedly Increased Rate

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: ALS is a fatal neurodegenerative disease in which motor neurons, cells that control muscle activity such as walking, talking and breathing, gradually die off, resulting in paralysis. There is no cure for ALS.
In a groundbreaking study published in the journal Neurology, and led by Mary-Louise Rogers, Ph.D., senior research fellow at Flinders University, Australia, and Michael Benatar, M.D., Ph.D, University of Miami, Miller School of Medicine, have identified concentrations of p75ECD, the extracellular domain on the common neurotrophin receptor p75, as the first biological fluid-based biomarker for ALS progression. .
Neurotrophin receptor p75 is a growth factor receptor for neurotrophins whom promote the survival of nerve cells. Under normal circumstances, it is highly expressed on motor neurons during development but decreases after birth. Following nerve injury, however, the expression of p75 is increased and the extracellular domain of p75 is detectable in urine. Dr Rogers and her Doctoral student Stephanie Shepheard hypothesized and then showed, that p75ECD is excreted into the urine of SOD1 mice, the most commonly used animal model of ALS. These findings empowered further investigation of p75ECD, showing raised levels in the urine of patients with ALS and that it might have potential as an ALS biomarker.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: BRCA testing in patients diagnosed with early-onset breast or ovarian cancer can identify women with high-risk mutations, which can guide treatment. Women who learn they have a high-risk mutation may also want to inform family members that they may also carry a high-risk mutation.
Additionally, BRCA testing can be used to identify high-risk mutation carriers before they develop breast or ovarian cancer. Carriers can then manage their cancer risks with screening (MRI/mammogram), chemoprevention, or prophylactic surgery. Current guidelines recommend BRCA testing for individuals who are considered high-risk for breast or ovarian cancer based on personal or family history. However, this practice fails to identify most BRCA mutation carriers. It is estimated that more than 90% of mutation carriers have not been identified. One of the issues is that many women who do get tested are actually low-risk and do not have any personal or family history of breast or ovarian cancer.
This study assessed how BRCA testing was used in the US health care system during the past decade. We found that in 2004 most of the tests (75.7%) were performed in patients who had been diagnosed with breast or ovarian cancer. Only 24.3% of tests were performed in unaffected women. However, since 2006, the proportion of BRCA tests performed in unaffected women has increased sharply, with over 60% of the tests performed in unaffected women in 2014.
24 Mar Based on Genetic Profile, Longer Adjuvant Treatment Recommended for Some GIST Tumors
MedicalResearch.com Interview with: Heikki Joensuu, MD Department of Oncology Helsinki University Hospital University of Helsinki Helsinki, Finland MedicalResearch.com: What is the background for this study? Response: The randomized Scandinavian Sarcoma Group (SSG) XVIII trial compared three years of adjuvant imatinib to one year of adjuvant imatinib as adjuvant treatments of patients who had undergone macroscopically complete surgery for a GIST with a high risk for tumor recurrence. In this trial, patients treated with 3 years of imatinib had improved overall survival as compared to those who were allocated to one year of adjuvant imatinib. In 2 other randomized trials that compared either 1 year of adjuvant imatinib to one year or placebo, or 2 years of adjuvant imatinib to observation, no improvement in overall survival was found, although in all three trials adjuvant imatinib improved recurrence-free survival (RFS). The reasons for the discrepant findings with respect of overall survival in the 3 trials have been unclear.24 Mar How Does Fruit Juice Affect Weight Gain in Children?

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: The question of whether 100% fruit juice causes poor health outcomes in children, such as weight gain, has been a subject of controversy. On one hand, 100% fruit juice contains vitamins and nutrients that many children lack, is often cheaper than whole fruit, and may help kids with limited access to healthy food meet their daily fruit requirements.
On the other hand, leading nutrition experts have expressed concern that fruit juice contains amounts of sugar equal to or greater than those of sugary drinks like regular soda. Guidelines from the American Academy of Pediatrics warn that 100% juice can be a significant source of calories and contribute to obesity if consumed excessively.
Our main finding was that consuming 1 serving/day of 100% fruit juice was not associated with weight gain in children. Children ages 1 to 6 years gained a small amount of weight, but not enough to negatively impact health. Children ages 7 and older gained no weight. We did not study amounts of 100% fruit juice higher than 1 serving/day.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Sleep apnea is a very common comorbidity of patients with heart failure (both reduced ejection fraction and preserved ejection fraction). Early evidence from observational and small studies suggested that treating sleep apnea with adaptive servo-ventilation (ASV) therapy may improve patient outcomes. There is minimal clinical evidence about identifying and treating sleep apnea in those who’ve been hospitalized with acute decompensated heart failure. The CAT-HF study was designed to help address this, with the primary endpoint being cardiovascular outcomes measured as a Global Rank Score that included survival free from cardiovascular hospitalization and change in functional capacity as measured by the six-minute walk distance. It was also planned to expand on the SERVE-HF study that was investigating the use of ASV therapy to treat central sleep apnea (CSA) in chronic stable heart failure patients with reduced ejection fraction patients (HFrEF).

MedicalResearch.com Interview with:
Zachary Borabm, Research fellow

NYU Langone Medical Center
MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Recent studies have shown that health care providers perform poorly in risk stratifying their patients for venous thromboembolism (VTE) which leads to inadequate VTE prophylaxis delivery, especially in surgical patients. Computerized Clinical Decision Support Systems (CCDSSs) are programs integrated into an electronic health record that have the power to aid health care providers. Using a meta-analysis study technique we were able to pool data from 11 studies, including 156,366 patients that either had CCDSSs intervention or routine care without CCDSSs.
Our main outcome measures were the rate of prophylaxis for VTE and the rate of actual VTE events. We found that CCDSSs increased the rate of VTE prophylaxis (odds ratio 2.35, p<0.001) and decreased the risk of VTE events (risk ratio 0.78, p<0.001).

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: This study builds on our previous work showing that weight-bearing, high-impact physical activity throughout the lifespan is associated with greater bone mass in men. We previously conducted a 12-month randomized trial of the effectiveness of resistance training versus jump training to increase bone mass in men with low bone density of the hip or lumbar spine.
The current study is a follow up study investigating how exercise might work to increase bone mass.
The main findings are that exercise reduced circulating levels of a bone protein that inhibits bone formation (sclerostin) and increased levels of insulin-like growth factor-I (IGF-I), a hormone with osteogenic effects.
23 Mar Gunshot Injuries Cost US Taxpayers Billions
MedicalResearch.com Interview with: Sarabeth Spitzer MD Candidate | MS2 Stanford University School of Medicine MedicalResearch.com: What is the background for this study? Response: While firearm homicides make headlines, they cause many more injuries than deaths.[1] No one had performed any recent analysis on the costs of hospitalizations for firearm-related injuries. Stanford is a Level One trauma center, and we care for patients injured by firearms. We wanted to know how much it costs the health system to treat these patients.23 Mar Coffee shops, 24-hour ATMs Best Locations For Public Cardiac Defibrillators
MedicalResearch.com Interview with: Christopher L.F. Sun MIE PhD candidate Department of Mechanical and Industrial Engineering University of Toronto, ON, Canada MedicalResearch.com: What is the background for this study? What are the main findings? Response: Strategic automated external defibrillator (AED) placement is critical for reducing the time to treatment and improving survival outcomes of public out-of-hospital cardiac arrest (OHCA). Many previous studies have focused on examining broad location categories without considering temporal availability (i.e. hours of operation). These broad location categories are often composed of many individual businesses, each with their own unique properties including varying accessibility. Examining specific businesses and locations while incorporating hours of operations and time of OHCA occurrence can improve AED placements in respect to where and when they are needed. Our goal was to examine individual businesses and municipal locations that maximize spatiotemporal OHCA coverage, the number of OHCAs that occurred within 100 m of each location when it was open. We identified a total of 41 businesses and municipal locations with 20 or more locations in Toronto to include the study. We proceeded to rank these businesses and municipal locations by spatiotemporal coverage. We found that coffee shops and bank automated teller machines (ATMs) were the best places to put public AEDs, corresponding to 8 of the "Top 10" ranking stop in Toronto. Specifically, the Canadian coffee shop chain Tim Hortons ranked first of all 41 businesses considered.23 Mar Land-Based Salmon Farms Degrade Natural Waters With Dissolved Organic Materials

MedicalResearch.com: What is the background for this study?
Response: Aquacultures are of great importance worldwide but pollute pristine headwater streams, lakes, and estuaries.
Chilean salmon production is economically important, contributing ~25% of the worldwide salmon yield
(Chile ranks second of the world’s salmon-producing countries). Salmon
farming has continuously increased in recent decades; the annual
salmonid production in Chile was 820,000 tons in 2012, representing a
value of 4.9 billion USD (32% of the total worldwide value of salmonid
production). Small salmon are reared in land-based aquacultures supplied
with stream water, whereas mid-sized fish are grown in cages in lakes
and adult fish in cages along the coast. The effluents from land-based
aquaculture pollute pristine streams with nutrients, antibiotics and
organic carbon, resulting in oxygen depletion and negative consequences
for the abundance and biodiversity of stream organisms. While
aquacultures have recently started to remove suspended matter from waste
water using sedimentation basins and rotating drum filters, dissolved
components are still discharged untreated. Nutrients and dissolved
organic matter (DOM) originating from the leaching of remaining food
pellets, fish faeces and fish excretions are major components released
by aquacultures. One aquaculture in northern Patagonia was estimated to
release DOM amounting to 21% of the carbon applied as feed and 76% of
the annual fish production.

Response: We based our research on recent findings that suggest that 70 percent of the adult U.S. population is overweight or obese. With that in mind, we wanted to find which metro areas offer the best environments for a healthy and active lifestyle.
Based on the report's methodology, we concluded that areas in the south tend to have higher overweight and obese rates, as some fail to offer residents healthy environments and amenities that would facilitate a more active lifestyle.

23 Mar High Risk Individuals Are Testing For HIV More Frequently
MedicalResearch.com Interview with: Qian An, PhD Epidemiologist/statistician Division of HIV/AIDS Prevention CDC MedicalResearch.com: What is the background for this study? Response: Since 2006, the Centers for Disease Control and Prevention (CDC) has recommended HIV testing for all persons aged 13-64 years old. Persons at high risk for HIV infection should be tested more frequently. Among sexually active men who have sex with men (MSM), repeat testing is recommended at least annually. An analysis in 2011 suggested that MSM might benefit from more frequent than annual testing.(1) Among non-MSM, repeat testing is recommended at least annually for persons at high risk, including persons who inject drugs (PWID) and their sex partners, those who have sex in exchange for money or drugs, heterosexuals who have had more than one sex partner since their most recent HIV test, and those whose partners are living with HIV.. Using statistical models based on renewal theory, we estimate the mean HIV inter-test interval (ITI) — meaning the average time period (in months) between two successive HIV tests — to describe temporal trends in HIV testing frequency among MSM, PWID and high-risk heterosexuals (HRH) and differences in testing frequency by age and race/ethnicity. A decrease in ITI means individuals are testing more frequently.23 Mar Reward Circuit in Brain Localized To Central Amygdala
MedicalResearch.com Interview with: Joshua Kim, researcher RIKEN-MIT Center for Neural Circuit Genetics at The Picower Institute for Learning and Memory, Department of Biology and Department of Brain and Cognitive Sciences, Massachusetts Institute of Technology, Cambridge, MA 02139, USA Howard Hughes Medical Institute, Massachusetts Institute of Technology Cambridge, MA 02139 MedicalResearch.com: What is the background for this study? Response: We previously identified to populations of neurons in a structure known as the basolateral amygdala, one that is capable of mediated fear-related behaviors and the other reward-related behaviors. Both of these basolateral amygdala populations send projections to a structure known as the central amygdala. For this study, we wanted to examine the function of 7 different populations of central amygdala neurons in regard to fear-related and reward-related function and how each of these 7 populations are connected to the 2 basolateral amygdala populations.23 Mar Association Between Cardiovascular Risk Factors and Aortic Stenosis
MedicalResearch.com Interview with: Andrew T. Yan, MD Terrence Donnelly Heart Centre St Michael's Hospital University of Toronto Toronto, Ontario, Canada MedicalResearch.com: What is the background for this study? What are the main findings? Response: The pathogenesis of aortic stenosis is complex and incompletely understood. Previous experimental data and epidemiologic studies (mostly cross-sectional) have demonstrated an association between conventional cardiovascular risk factors such as hypertension, diabetes, and dyslipidemia, and aortic sclerosis or stenosis. However, there is a paucity of longitudinal data from large population studies. Therefore, we sought to examine the relationship between conventional cardiovascular risk factors and incident severe aortic stenosis during extended follow-up in a large unselected elderly population in Ontario, Canada. In over 1 million individuals older than 65 who were followed for a median of 13 years, hypertension, diabetes and dyslipidemia were all significantly and independently associated with development of severe aortic stenosis requiring hospitalization or intervention. Furthermore, we observed a positive dose-response relationship between the number and duration of cardiac risk factors, and the risk of aortic stenosis. Together, these risk factors accounted for approximately one third of the incidence of severe aortic stenosis at a population level.23 Mar Development and Assessment of BPX-01, a Novel Topical Minocycline Gel for Treatment of Acne Vulgaris
MedicalResearch.com Interview with: Usha Nagavarapu, PhD Senior director of preclinical drug development BioPharmX MedicalResearch.com: What is the background for this study? What are the main findings? Response: Acne vulgaris is a complex chronic inflammatory disease known to be linked with P. acnes and can have profound social and psychological effects. Though a number of treatments exist, there is promise of a long-term benefit for acne patients. BioPharmX’s in vitro and in vivo studies have revealed that a low-dose, topical 1% minocycline gel (BPX-01) provided a localized and targeted delivery of adequate minocycline to the epidermis and pilosebaceous units that can potentially limit systemic exposure and may reduce treatment related side effects. At the intended clinical dose, toxicity and safety animal studies found that BPX-01 was well tolerated with no significant local or systemic toxic effects. A comparative animal study with oral minocycline demonstrated that topical application of minocycline can limit systemic exposure while delivering sufficient minocycline to the skin to treat acne vulgaris. Along the same lines, a 4-week clinical study with extended release oral minocycline to assess the skin and plasma concentrations of minocycline was conducted. A marked reduction of mean acne lesion counts from baseline was seen with oral minocycline with presence in plasma. On the contrary no minocycline was identified in the skin from periauricular biopsies. Recently, BioPharmX completed a 4-week Phase 2 clinical repeat-dose study of BPX-01. The minocycline gel was well tolerated and over 90% of P. acnes were eliminated. A 12-week Phase 2 dose-finding clinical trial to further assess the efficacy and safety of BPX-01 for the treatment of moderate-to-severe, non-nodular inflammatory acne vulgaris has been initiated. The dose-finding study will provide additional support for the planned Phase 3 clinical trial program with BPX-01.22 Mar Educational Disparities in Mortality Between Adults Aged 50–64 and 66–79 Years, U.S.
MedicalResearch.com Interview with: Jiemin Ma PhD MHS Strategic Director, Cancer Interventions Surveillance American Cancer Society, Inc. Atlanta, GA 30303 [caption id="attachment_33223" align="alignleft" width="153"]
Dr. Jiemin Ma[/caption]
MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Previous studies have shown that educational disparities are smaller in the elderly than in working-aged Americans. The differences may partly be explained by the higher health insurance coverage among the elderly (near universal coverage through Medicare for adults aged 65), as well as some aging-related changes in lifestyle and social factors (e.g. retirement). Some of the previous studies were limited by the use of proxy-reported educational information, which tended to be inaccurate for the elderly.
Our study used self-reported educational attainment to estimate relative differences in educational disparities in mortality rates between adults aged 50–64 and 66–79 years in a national representative cohort from the National Longitudinal Mortality Study (NLMS).
We found that educational disparities in all-cause mortality for ages 66–79 years were about 41% and 61% lower than those for ages 50–64 years in non-Hispanic whites and non-Hispanic blacks, respectively. Diminished disparities in the elderly were also found for deaths from cardiovascular disease and cancer among non-Hispanic Americans.
22 Mar Intracoronary Nitroglycerin, the Forgotten Stepchild of Cardiovascular Guidelines
MedicalResearch.com Interview with: Alec Vishnevsky, MD Cardiology Fellow and First Author Thomas Jefferson University Hospital Michael P. Savage, MD FACC FSCAI FACP Ralph J. Roberts Professor of Cardiology Sidney Kimmel Medical College at Thomas Jefferson University Director, Cardiac Catheterization Laboratory MedicalResearch.com: What is the background for this study? What are the main findings? Response: Percutaneous coronary intervention (PCI) has been a mainstay treatment for patients with symptomatic coronary artery disease. While current guidelines emphasize the importance of periprocedural antithrombotic medications, they fail to mention the use of nitroglycerin prior to PCI to rule out coronary artery spasm as the etiology of a stenosis seen on coronary angiography. This distinction is paramount as it can avoid unnecessary stenting procedures. In this case series, we described a series of patients presenting with chest pain and angiographically significant stenoses that resolved with administration of intracoronary nitroglycerin (IC NTG) prior to planned PCI. The study group consisted of 6 patients with a mean age of 52, all of whom had anginal symptoms and significant stenoses seen on coronary angiogram. In each case, giving intracoronary nitroglycerin resulted in resolution of the stenosis, and all 6 patients were successfully managed medically without stenting.22 Mar Autism Increases Risk of Death From Injury, Especially Drowning
MedicalResearch.com Interview with: Joseph Guan MPH Candidate in Epidemiology, Certificate in Chronic Diseases Epidemiology Columbia University Mailman School of Public Health MedicalResearch.com: What is the background for this study? What are the main findings? Response: The prevalence of autism has been increasing especially in the past two decades. With an estimate of more than 3.5 million people living with autism in the US, approximately 500,000 of them are children under 15 years old. Current studies show that males are approximately four times as likely than females to be diagnosed with autism. There is also evidence that people with autism are at a heightened risk of injury. However, the research on the relationship between autism and injury is understudied. We found that 28% of deaths in individuals with autism were due to injury, compared to 7% of deaths in the general population. Injury deaths in individuals with autism occurred at a much younger age (29.1 years) on average compared to injury deaths in the general population (54.7 years). Our study show that drowning was the leading cause of injury death among individuals with autism, followed by suffocation and asphyxiation. Children under the age of 15 years were 160 times more likely to die from drowning.21 Mar Diabetic Retinopathy: OCTA May Improve Staging, Diagnosis and Monitoring

Response: In this study, we evaluated the clinical utility of quantitative measures of microvasculature in optical coherence tomographic angiography (OCTA). Although several studies have demonstrated the potential value of measures of microvasculature in the management of diabetic retinopathy (DR), our study uses the ROC curve to compare the overall value of different approaches. In this age matched population with a range of disease, the mean vessel density measured in the SRL had the highest AUC, indicating that it is best among the methods tested at differentiating normal eyes from eyes with diabetic retinopathy.

Response: There’s so much in the news about health care today. It’s on people’s mind more than ever before due to rising costs and deductibles and, of course, the repeal debate.
With that in mind, we wanted to see how the current landscape affects two things: 1) People’s trust in the health system in general; and 2) Their attitude towards the doctor-patient relationship.
It shouldn’t be surprising that different generations had different perceptions. But we were amazed by how some generational stereotypes held true when it came to doctor-patient relationships and the health care attitudes.
Millennials – Health Care Idealists
Being in their 20s and 30s, Millennials are young and in general a healthy bunch. For the most part, they’ve utilized less health care services than other generations. Only 35 percent have a primary care provider, and one in four say they use an alternative care facility, like an urgent care center, when they are sick.
Often characterized as optimistic and idealistic, those traits may help explain why they have a high degree of trust in the system and in their doctors. They’re the least likely to question their doctor’s authority or their integrity when it comes to fessing up to medical mistakes.
Confident and idealistic, Millennials are often labeled as over-sharers for their habits both on social media and in the real world. But this translates into an open doctor-patient relationship. Millennials are more likely than other generations to say they can tell their doctor “anything.” Perhaps a byproduct of their parents raising them to believe their voice matters, Millennials have an expectation that they can and should engage authority. Yet, that collaborative and open dialogue leads to another positive: They’re the most likely to follow their doctor’s medical advice.
Millennials have grown up as digital natives. As such, they’re the most likely to use online reviews to “check up” on a new doctor. Yet, their familiarity with technology leads them to be the least suspicious of pitfalls. More than other generations, Millennials trust health facilities with their personal health information.
