Author Interviews, Nutrition, Social Issues / 10.05.2017

MedicalResearch.com Interview with: Jay L. Zagorsky Center for Human Resource Research The Ohio State University and Patricia K. Smith PhD Department of Social Sciences University of Michigan-Dearborn MedicalResearch.com: What is the background for this study? Response: The prevalence of adult obesity in the U.S. has risen substantially, from about 13% in the early 1960s to nearly 38% now.  Obesity is associated with a variety of illnesses and imposes significant costs on individuals and society. Socioeconomic (SES) gradients in health and the prevalence of disease, including obesity, have been documented: health improves and disease prevalence falls as we move up each step of the SES ladder.  Differences in nutrition could help explain these health gradients and Americans commonly think the poor eat fast food more often than those in the middle and upper classes. Policy based on this notion has been proposed.  For example, in 2008 Los Angeles placed a moratorium on new fast-food restaurants in poor neighborhoods. (more…)

MedicalResearch.com Interview with: Tarani Chandola Professor of Medical Sociology Social Statistics Disciplinary Area of the School of Social Sciences University of Manchester MedicalResearch.com: What is the background for this study? Response: We (the authors) were particularly interested in examining evidence for the common perception that people at the top of the occupational hierarchy are the most stressed. And also what happens to people’s stress levels when they retire. We had assumed that people with poorer quality work to have decreased levels of stress when they retired. There have been other studies on this topic before, but none that have used salivary cortisol to measure physiological stress responses. We analysed changes in people’s stress levels before and after retirement, in a follow up study of over 1,000 older workers in the British civil service. Stress levels were measured by taking salivary cortisol samples across the day, from awakening until bedtime. (more…)

MedicalResearch.com Interview with: Wendy Tan Senior Medical Social Worker Medical Social Work The National Kidney Foundation MedicalResearch.com: What is the background for this study? Response: End Stage Renal Disease (ESRD) patients experience significant changes to their daily routine and lifestyle. Their time and attention were often centred solely on their sickness whilst receiving treatment accentuating the employment isolation. This study determined the need for extra support to assist patients adjust (e.g. learning about their psychological wellbeing, change of role and mindset, suitable work conditions and employment support) in returning to work. It also sheds light on how individuals perceive the particular situations they are facing, how they are making sense of their health conditions and the society at large in relations to seeking continued employment.

MedicalResearch.com Interview with: Ms. Shifra Mincer Medical Student in the class of 2019 SUNY Downstate Medical School MedicalResearch.com: What is the background for this study? What are the main findings? Response: Hypophosphatemia is commonly encountered in the post-transplant setting. Early post-transplant hypophosphatemia has been ascribed to excess FGF23 and hyperphosphaturia. Many patients remain hypohosphatemic months or even years after their transplant and the mechanism was assumed to be the same, however, our group recently reported that patients with late post-transplant hypophosphatemia had very little phosphorous in their urine (Wu S, Brar A, Markell, MS. Am J Kidney Dis. 2016,67(5): A18). We hypothesized that they were not eating enough phosphorous to compensate for the acute phosphorous losses they experienced immediately post-transplant. In this study, using both 3-day diet journals and 24-hour diet recall questionnaires, we found that mean intake of phosphorous and protein was barely at the Recommended Daily Allowance, and that despite 70% of the patients using EBT, 30% of those patients still reported concerns regarding food security. Patients who reported that the cost of food influenced their dietary choices ate 43% less protein (average 48,5 gms vs. 85.8 gms) and 29% less phosphorous (average 887 mg vs 1257 mg). When ability to rise from a chair over a 30 second period was evaluated, only patients who expressed food cost concerns were unable to complete the test. (more…)

MedicalResearch.com Interview with: Madeleine A. Fugère, Ph.D. Professor of Psychology Eastern CT State University Willimantic, Connecticut MedicalResearch.com: What is the background for this study? What are the main findings? Response: Previous research has shown that both daughters and their parents rate many traits as more important than physical attractiveness in a potential mate (for daughters), including traits such as respectfulness, honesty, and trustworthiness. Previous research also shows that women rate physical attractiveness as more important in a mate for themselves than parents do in a mate for their daughters. In our research project, we experimentally manipulated the physical attractiveness of male targets (using photographs) and we experimentally manipulated the traits associated with each male target. The trait profiles included the “respectful” trait profile which consisted of the traits respectful, honest, and trustworthy, the “friendly” trait profile which included the traits friendly, dependable, and mature, and the “pleasing” trait profile which contained the traits pleasing disposition, ambitious, and intelligent. We found that both women and their mothers were strongly influenced by the physical attractiveness of the men and preferred the attractive and moderately attractive targets. Both women and their mothers rated the attractive and moderately attractive men most favorably, especially when they were paired with the most positive trait profile (the “respectful” trait profile). However, the unattractive man was never rated more positively than his more attractive counterparts even when he possessed the most favorable trait profile. (more…)
Author Interviews, Genetic Research, Social Issues / 15.03.2017

MedicalResearch.com Interview with: Emily Rauscher PhD Assistant Professor Department of Sociology University of Kansas   MedicalResearch.com: What is the background for this study? Response: A lot of previous research has identified genotypes that increase sensitivity to context.  Much of this research, however, looks at particular aspects of health and is not able to address the methodological challenges of investigating gene-environment interactions.  To gain a better sense of the potential outcomes that may be susceptible to gene-environment interactions, I examine financial standing in young adulthood.  Testing this type of interaction is challenging because genotype and social environment are not randomly distributed throughout the population. Given this non-random distribution, unobserved confounders (such as parental behaviors, education, ethnicity, or social capital) could influence both parent and child financial standing. (more…)
Aging, Author Interviews, Geriatrics, Karolinski Institute, Social Issues / 14.03.2017

MedicalResearch.com Interview with: Dr. Karin Modig, PhD Institute of Environmental Medicine,Epidemiology Karolinska Institute MedicalResearch.com: What is the background for this study? Response: The background to the study was that even though it is established that parents live longer than non-parents the underlying mechanisms are not clear. And it was not known how the association changed with the age of the parents. We hypothesize that if social support is one mechanism – the association between having children and the death risk of parents-non-parents would increase with age of the parents, when health starts to deteriorate and the need of support increases.

MedicalResearch.com Interview with: Brooke E. Wells, Ph.D. Associate Professor & PhD Program Director Center for Human Sexuality Studies Widener University One University Place Chester, PA 19013 MedicalResearch.com: What is the background for this study? Response: It is widely believed that Americans today are more sexually liberated and open than ever before. While research indicates that Americans do indeed have more liberal attitudes about a range of sexual behaviors, Americans are actually reporting fewer sexual partners and higher rates of adult sexual abstinence. But are Americans reporting similar levels of sexual frequency with fewer partners? Our research set out to examine changes over time in sexual frequency to better understand our changing sexual landscape. (more…)
Author Interviews, Social Issues / 09.03.2017

MedicalResearch.com Interview with: Ella Daniel, PhD Department of School Counseling and Special Education Constantiner School of Education Tel Aviv University MedicalResearch.com: What is the background for this study? Response: The development of disruptive behavior in early childhood is extremely important, as disruptive behavior starts early in life and behavioral patterns may become stable and resistant to influence later on. Siblings have a high potential to influence each other's behavior, as they spend a considerable amount of time together, are close in age and likely to become role models. However, the role of siblings in disruptive behavior development was mostly studied among adolescents, and hardly among young children. In the current study, conducted in collaboration with Dr. Jennifer Jenkins and colleagues at the University of Toronto and funded by the Canadian Institute for Health Research, we asked parents in some 400 families in and around Toronto, about the behavior of their young children. Both mothers and fathers reported the frequency of disruptive behaviors among their children, including violence, disobedience, destruction of property etc.. At the time of the study, the youngest children in the family were only 18 months of age. They all had an older sibling who was less that 5.5 years of age, and some had additional older siblings, up to four children in a  amily. Using advanced statistical models, we aimed to identify the role of siblings in the development of each child's disruptive behavior over time, taking into account heredity, parenting, social environment and shared history.

Author Interviews, Genetic Research, Social Issues, Weight Research / 08.03.2017

MedicalResearch.com Interview with: Professor Don Haider-Markel Chair, Department of Political Science University of Kansas Lawrence, KS 66045 MedicalResearch.com: What is the background for this study? Response: We have studied causal attributions for conditions and problems in society for some time. We noticed that public debate over obesity had increased and new policy proposals were being proposed to address what was deemed as a growing public health problem. As the salience of the issue increased so too did partisan views on the topic. Based on these observations, we wanted to explore individual beliefs about the causes, or attributions for, obesity. Existing research and theory suggested that Republicans following a conservative philosophy would be more likely to attribute obesity to personal choices, such as eating habits and lack of exercise—in short, putting the locus of control on individuals. Meanwhile liberal leaning Democrats, with a known predisposition to suggest conditions or problems are outside of the control of the individual, would be more likely to attribute obesity to either genetic or other biological factors, or the broader context of widely available low-cost high-fat food sources. Additionally, we know that individuals tend to make attributions that are self-serving. In other words, people tend to make attributions that put themselves in a positive light. Thus, personal weight should factor into obesity attributions. Here we expected that overweight people would be more likely to make attributions that removed personal blame, such as pointing to a genetic cause. People closer to an ideal weight would, on the other hand, be more likely to attribute weight-level to personal choices. (more…)
Author Interviews, Mental Health Research, Pediatrics, Social Issues, Stroke / 28.02.2017

MedicalResearch.com Interview with: Emily C. Maxwell, Ph.D. Pediatric Neuropsychology Bugher Fellow Division of Neurology Instructor | Department of Pediatrics University of Colorado School of Medicine Aurora, CO 80045  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Previous research has found increased psychological problems and significantly higher rates of psychiatric disorders after pediatric stroke. However, past studies have mainly used global indices, without comparison to age-based norms. Thus, little is known about the discrete symptomatology exhibited by these children and how discrepant these symptoms may be from normative expectations. At the University of Colorado Denver and Children’s Hospital Colorado, we studied 50 patients who suffered an arterial ischemic stroke during childhood. The parents of these patients completed the Child Behavior Checklist, a questionnaire assessing emotional and behavioral problems. We found that children with stroke had higher symptoms of depression, anxiety, physical complaints, and behavioral difficulties compared to a normative sample of same-aged peers. Additionally, levels of anxiety were higher in children who had a stroke at an early age (before 6 years of age) compared to children who had a stroke at a later age (after 10 years of age). (more…)

CPT, MC, USA Medical Director, Intrepid Spirit, Traumatic Brain Injury Clinic Staff Neurologist, Department of Medicine Teaching Fellow, Uniformed Services University Carl R. Darnall Army Medical Center Fort Hood, Texas 76544 MedicalResearch.com: What is the background for this study? Response: Racial and Socioeconomic disparities in the outcomes of stroke patients is well documented in the US Civilian Healthcare system. That Healthcare system has wide variations in access to care and in the levels of available care. In contrast, the Military Healthcare system is a single payer system meaning that every member has the same healthcare benefits. (more…)

MedicalResearch.com Interview with: Nicholas H. Wolfinger PhD Professor, Department of Family and Consumer Studies Adjunct Professor, Department of Sociology University of Utah Salt Lake City, UT 84112-0080 MedicalResearch.com: What is the background for this study? What are the main findings? Response: W. Bradford Wilcox and I have been studying marriage and divorce for fifteen years. Last year we published Soul Mates: Religion, Sex, Love and Marriage among African Americans and Latinos (Oxford University Press). We’re always looking for opportunities to present our findings to the public, so Valentines Day is a great excuse! It’s probably too strong a statement to call our new research brief a study, as we’re not offering any novel findings. Instead, we’re just compiling data from different sources—some published by other scholars, some based on our own analysis of national data—to reaffirm a basic point: marriage is good for men in myriad ways (Marriage is also good for women, but they await their own research brief.) In particular, marriage offers these benefits to men:
  • Higher earnings, greater assets and more job stability. Married men make about $16,000 a year more than their single peers with otherwise similar backgrounds.
  • Better sex lives compared to both single and cohabiting men. According to data from the National Health and Social Life Survey, 51 percent of married men report they are extremely emotionally satisfied with sex, compared to 39 percent of cohabiting men and 36 percent of single men.
  • Longer and happier lives. Men who get and stay married live almost 10 years longer than their unmarried peers. Also, young married men are about twice as happy: 43 percent of married men report they are “very happy” with life, compared to 20 percent of single men and 24 percent of cohabiting men.

Accidents & Violence, Author Interviews, Pediatrics, Social Issues, University of Pittsburgh / 21.02.2017

MedicalResearch.com Interview with: Christian D. Pulcini, MD, MEd, MPH Pediatric Resident Children's Hospital of Pittsburgh of UPMC Chair, Section on Pediatric Trainees (SOPT) American Academy of Pediatrics MedicalResearch.com: What is the background for this study? What are the main findings? Response: Poverty influences the well-being of children and adolescents in a negative way. Poor children are often exposed to toxic health stressors, including violence, environmental toxins, and inadequate nutrition. Children in poverty with chronic health conditions also are more likely to have higher rates of secondary disorders and worse outcomes. We studied children with asthma, attention-deficit/hyperactivity disorder (ADHD), and autism spectrum disorder (ASD), to describe the how much disease and if the children had multiple (comorbid) conditons and how these vary by poverty status. Parents reported through the National Survey of Children's Health that asthma and ADHD rose 18% and 44% from 2003-2011/2012, respectively, whereas the lifetime prevalence of ASD rose 32% from 2007-2011/2012 in all income levels. For asthma, the rise was most among the poor at 25.8%. For ADHD, the percent change among the poor was similar, however the rise in autism spectrum disorder was associated with being non-poor. Publicly insured children with asthma, ADHD, and ASD also had a significant higher chance (1.9×, 1.6×, 3.0×, respectively) of having higher more than one chronic condition. In addition, kids who were poor with asthma and ADHD. (more…)

MedicalResearch.com Interview with: James K. Rilling, PhD Professor, Anthropology, Psychiatry and Behavioral Science Emory University School of Medicine MedicalResearch.com: What is the background for this study? What are the main findings? Response: It has been known for a long time that female mammals experience hormonal changes during pregnancy that prepare them to care for their offspring. More recently, it has been shown that some mammalian males, including humans, can also experience hormonal changes that prepare them to care for their offspring. For example, oxytocin levels can increase in human fathers and studies have shown that oxytocin facilitates paternal physical stimulation, play and emotional synchrony with their children. We examined the effects of intranasal oxytocin on brain function in human fathers. We found that intranasal oxytocin increased activation in brain areas involved with reward and empathy when human fathers viewed pictures of their children, but not unknown children. (more…)
Abuse and Neglect, Author Interviews, Social Issues / 18.02.2017

MedicalResearch.com Interview with: Andrew Fenelon PhD Assistant Professor, Department of Health Services Administration University of Maryland School of Public Health. College Park, MD 20742 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Despite the relatively large public investment in housing assistance at the federal level, there have been few nationwide analyses of the impacts of these programs on health and well-being. And as policymakers seek solutions to health disparities that incorporate some of the non-medical determinants of health (such as housing quality), our study can make an important contribution to both health and housing policy. We use an innovative data linkage program which links individuals in a federal household health survey and administrative housing records from the U.S. Department of Housing and Urban Development (HUD). We examine the health impacts of three HUD housing programs: public housing, housing choice vouchers, and multifamily housing. We find that public housing and multifamily housing lead to an improvement in self-reported health status, and public housing leads to a reduction in serious psychological distress. We do not find health impacts associated with housing choice vouchers. (more…)

MedicalResearch.com Interview with: Brian Chin, B.S. PhD Student Doctoral Student Department of Psychology Carnegie Mellon University MedicalResearch.com: What is the background for this study? What are the main findings? Response: Numerous studies demonstrate that married people tend to be healthier than those who are single, divorced, or widowed. However, less clear are the psychological and biological mechanisms through which this occurs. To this end, recent research has focused on how the unmarried may experience either greater amounts of stress or different types of stressful situations that put them at increased risk for morbidity and mortality. Models linking stress and disease often implicate the HPA axis as one pathway through which these stressful experiences can affect health. One way to index HPA axis activity is by measuring cortisol, a hormone that plays a regulatory role for many immunological and metabolic processes in the body. The primary aim of our study was to examine whether cortisol could be one biological mechanism through which marital status impacts health. Over three non-consecutive days, 572 healthy adult participants between 21-55 years old provided multiple saliva samples that were used to measure cortisol. Relative to their never married or previously married counterparts, married people had both lower cortisol outputs and steeper daily declines – both of which have been shown to be associated with better health outcomes.

MedicalResearch.com Interview with: Sanne Peters, PhD Research Fellow in Epidemiology The George Institute for Global Health University of Oxford Oxford United Kingdom MedicalResearch.com: What is the background for this study? Response: People from disadvantaged backgrounds are, on average, at greater risk of cardiovascular diseases than people with more affluent backgrounds. Some studies have suggested that these socioeconomic inequalities in cardiovascular disease are more consistent and stronger in women than in men. However, the literature is inconsistent. (more…)

MedicalResearch.com Interview with: PD Dr. René Proyer Martin-Luther-Universität Halle-Wittenberg Institut für Psychologie Abteilung Differentielle Psychologie und Psychologische Diagnostik MedicalResearch.com: What is the background for this study? Response: I got interested in the study of playfulness and adult playfulness in particular while I was working in the Psychology Department at the University of Zurich in Switzerland. There we worked with the so-called Values-in-Action (VIA) classification of strength and virtues (developed by Chris Peterson and Martin Seligman). In this classification humor and playfulness are being used synonymously. One of my first aims was testing whether this reflects their relation or whether they should be used separately. Overall, findings suggest that there is a relationship, but that the two are not redundant and should be studied separately. From there my interest in the field grew and I started reading more and more. It soon was clear that playfulness is an understudied individual differences variable and that current conceptualizations focus primarily on the facets of playfulness that are associated with fun and entertainment, while disregarding others. My research is aimed at narrowing some gaps in the literature and developing a structural model of how adult playfulness could be understood. (more…)
Author Interviews, Brigham & Women's - Harvard, Heart Disease, Lancet, Medical Imaging, MRI, Social Issues / 12.01.2017

MedicalResearch.com Interview with: Dr Ahmed Tawakol MD Co-Director, Cardiac MR PET CT Program Massachusetts General Hospital and Harvard Medical School  MedicalResearch.com: What is the background for this study? What are the main findings? Response: While the link between stress and heart disease has long been established, the mechanism mediating that risk hasn’t been clearly understood. Animal studies showed that stress activates bone marrow to produce white blood cells, leading to arterial inflammation.  This study suggests an analogous path exists in humans. Moreover, this study identifies, for the first time in animal models or humans, the region of the brain (the amygdala) that links stress to the risk of heart attack and stroke. The paper reports on two complementary studies. The first analyzed imaging and medical records data from almost 300 individuals who had PET/CT brain imaging, primarily for cancer screening, using a radiopharmaceutical called FDG that both measures the activity of areas within the brain and reflects inflammation within arteries.  All participants in that study had no active cancer or cardiovascular disease at the time of imaging and each had information in their medical records on at least three additional clinical visits after imaging. The second study enrolled 13 individuals with a history of post-traumatic stress disorder, who were evaluated for their current levels of perceived stress and received FDG-PET scanning to measure both amygdala activity and arterial inflammation.

Aging, Author Interviews, Social Issues / 25.12.2016

MedicalResearch.com Interview with: Sonja Hilbrand MSc Department of Psychology University of Basel Basel, Switzerland. MedicalResearch.com: What is the background for this study? Response: Grandparenting is a topic of both great practical and theoretical interest. For instance, grandparents in industrialized societies invest substantial amounts of time and money in their grandchildren and there are many studies examining the potential benefits for these grandchildren. Other studies have focused on potentially negative effects on grandparental mortality associated with providing custudial care for grandchildren. In addition to previous research we wanted to ask whether there are tangible benefits to the donors (grandparents) of the resources. In other words, is caring a one-way street or not. In our study we examined whether moderate amounts of caregiving were associated with the longevity of older adults. For our analysis we used longitudinal data of over 500 German individuals aged between 70 and 103 years. (more…)
Author Interviews, Blood Pressure - Hypertension, Genetic Research, PLoS, Race/Ethnic Diversity, Social Issues / 25.12.2016

MedicalResearch.com Interview with: Connie J. Mulligan, PhD Professor, Department of Anthropology University of Florida Gainesville, FL MedicalResearch.com: What is the background for this study? Response: Lance Gravlee (UF Dept of Anthropology, UF Genetics Institute) started this research over 10 years ago. As a cultural anthropologist, Lance uses ethnographic (open-ended questions) interviews and discovered that over half of the participants in our study talked about experiences of discrimination that happened to people close to them. As a geneticist (UF Dept of Anthropology, UF Genetics Institute), I came into the project because I was interested in seeing how genetics and sociocultural stressors, like discrimination, interact. In our project, we look at blood pressure because hypertension is a disease that shows racial disparities and also because it is a complex disease that is caused by both genetic and environmental factors (like discrimination).

MedicalResearch.com Interview with: Matthew E. Dupre, Ph.D. Associate Professor Department of Community and Family Medicine & Duke Clinical Research Institute (DCRI) Duke University MedicalResearch.com: What is the background for this study? What are the main findings? Response: There have been a handful of recent studies showing how divorce and widowhood increase one’s risk of suffering a serious health event such as a heart attack or stroke. Our research is the first to show that an individual’s marital history can have significant consequences for their prognosis after having a stroke. We found that people who never married and those with a history of marital loss were significantly more likely to die after suffering a stroke than those who were stably married. We also found that adults who experienced more than one divorce or widowhood in their lifetime were about 50% more likely to die after having a stroke than those in a long-term stable marriage. We were also somewhat surprised to find that remarriage did not seem to reduce the risks from past marital losses. (more…)

MedicalResearch.com Interview with: Jonathan Y. Bernard, PhD Inserm UMRS 1153 – Centre for research in Epidemiology and Biostatistics Sorbonne Paris Cité (CRESS) Team ORCHAD: early Origin of the Child Health And Development Hôpital Paul Brousse MedicalResearch.com: What is the background for this study? What are the main findings? Response: Despite the World Health Organization’s recommendations promoting breast feeding, wide variations in breast feeding initiation rates are observed among Western countries: some reach >95%, while others remain <80%. Many individual-level determinants of breast feeding are known, including maternal age, education, ethnicity, smoking and employment status. Less is known regarding cultural determinants, such as religion, which could be underlying and explain rate differences between and within countries. We aimed at comparing countries’ breast feeding rates with the proportions of Catholics and Protestants. We thus carried out an ecological study by collating publicly available online data for 135 countries. We additionally gathered within-country data for 5 Western nations: France, Ireland, the UK, Canada and the USA. We found that, in Western countries, the proportion of Catholics was negatively correlated with the rate of breast feeding. This was also observed within countries in France, Ireland, the UK and Canada. In the USA, where breast feeding rates vary hugely between states, race was an important confounder. Interestingly, we also found the correlation in non-Hispanic whites. All our findings hold even when we account for wealth indicators, such as gross domestic product per capita. (more…)
Author Interviews, Gender Differences, Ophthalmology, Social Issues / 02.12.2016

MedicalResearch.com Interview with: Antoine Coutrot PhD CoMPLEX University College London London, UK MedicalResearch.com: What is the background for this study? What are the main findings? Response: The human face is central to our everyday social interactions. Recent studies have shown that while gazing at faces, each one of us has a particular eye-scanning pattern, highly stable across time. Although variables such as culture or personality have been shown to modulate gaze behavior, we still don't know what shapes these idiosyncrasies. Moreover, most previous observations rely on analyses of small-sized eye-position datasets, often from the WEIRD (western, educated, industrialized, rich, and democratic) population. Here we use a very large and diverse dataset (400+ participants from 58 nationalities) and show that among many observer characteristics, gender is the one that best explains the differences in gaze behaviour. When looking at faces, women are more exploratory than men and more biased toward the left side. We even trained a classifier able to infer the gender of observers only based on their gaze. (more…)

MedicalResearch.com Interview with: Charles Opondo, BPharm MSc PhD. Researcher in Statistics and Epidemiology National Perinatal Epidemiology Unit Nuffield Department of Population Health University of Oxford Oxford MedicalResearch.com: What is the background for this study? What are the main findings? Response: Our study measured fathers’ involvement in their child’s upbringing in infancy by looking at their emotional response to their child (e.g. feeling confident with the child, making a strong bond with the child), how involved they were in childcare (e.g. changing nappies, playing, night feeding, and also general care tasks around the house such as meal preparation) and their feelings of being a secure in their role as a parent (e.g. feeling included by mother in childcare, not feeling inexperienced with children). We found that the children of fathers who scored highly in terms of their emotional response and feeling like a secure parent were less likely to have symptoms of behavioural problems when they were 9 or 11 years. However, fathers being more involved in direct childcare did not seem to affect the child’s risk of having later behavioural problems. (more…)

MedicalResearch.com Interview with: Carlota Batres, Ph.D. Perception Lab School of Psychology and Neuroscience University of St Andrews UK MedicalResearch.com: What is the background for this study? Response: The background for this study is that previous research had found that people in different environments prefer different faces, which suggests that preferences change according to the environment. However, because previous research had never tracked the same participants across environmental changes, such a link could not be confirmed. Therefore, we sought to determine if, and to what extent, face preferences were malleable by repeatedly testing participants whose environment was not changing as well participants undergoing intensive training at an army camp.

MedicalResearch.com Interview with: Adam L. Beckman Yale College, New Haven, CT (at the time this work was completed) Erica S Spatz MD MHS Assistant Professor, Section of Cardiovascular Medicine Center for Outcomes Research and Evaluation Yale-New Haven Hospital Yale University School of Medicine MedicalResearch.com: What is the background for this study? Beckman: Despite the expansion of insurance coverage, young adults face major challenges to obtaining affordable healthcare. We suspected women may experience greater challenges than men — they often have lower income and less complete medical coverage than men, and care for multiple generations of family, and that this may in part explain why young women have worse outcomes following a heart attack as compared with similarly-aged men.

MedicalResearch.com Interview with: Anita P. Barbee, MSSW, Ph.D. Professor and Distinguished University Scholar President-Elect, International Association for Relationship Research Kent School of Social Work University of Louisville Louisville, KY 40292 MedicalResearch.com: What is the background for this study? Response: In 2010, our team at the University of Louisville with colleagues from Spalding University, were awarded a Tier 2 grant from the Office of Adolescent Health to study innovative teen pregnancy prevention interventions. We assembled a fantastic team of staff, students, community members and twenty three community based organizations to work together collaboratively to recruit and retain close to 1450 youth from the most distressed areas of our metropolitan area in order to conduct a randomized controlled trial. We tested the efficacy of two interventions compared to a control condition. Our reason for this was to see how a new type of teen pregnancy intervention would perform compared to a more typical comprehensive sex education program, Reducing the Risk, which was already on the OAH list of evidence based interventions as well as to a control condition, which focused on community building but had no content on personal self esteem building, healthy relationships, dating violence or sexuality. The new program that was tested was Love Notes. Love Notes is a healthy relationship curriculum that addresses the context of sexual exploration as well as key points in preventing problematic outcomes of sexual activity such as the spread of disease, pregnancy and emotional heartache. The groups of youth that continue to have high rates of pregnancy tend to be disconnected from society through poverty and discrimination (minority and poor youth) or from family as a result of leaving home countries (refugees and immigrants), being removed from their homes due to child abuse or neglect (foster youth) or being rejected from families due to their LGBTQ orientations.
