Socio-Economic Factors Influence Genetic Tendency Toward Obesity

MedicalResearch.com Interview with: Professor Timothy Frayling PhD Professor of Human Genetics University of Exeter Medical School Exeter, UK MedicalResearch.com: What is the background for this study? What are the main findings? Response: We know that genes and environmental factors influence our Body mass index. We know less about if and how they interact. We wanted to answer the question of whether or not aspects of the environment and our lifestyles accentuate any genetic predisposition to obesity. The question is important as it may highlight aspects of the environment that cause some people to be particularly susceptible to gaining weight. Previous, separate, studies have suggested that specific aspects of the environment are to blame. These included sugary drinks, fried food and TV watching. (more…)

Brain Scans Can Predict Specific Spontaneous Emotions

MedicalResearch.com Interview with: Kevin S. LaBar, Ph.D. Professor and Head, Cognition & Cognitive Neuroscience Program Co-Director of Undergraduate Studies in Neuroscience Center for Cognitive Neuroscience Duke University Durham, NC MedicalResearch.com: What is the background for this study? What are the main findings? Response: Emotion research is limited by a lack of objective markers of emotional states. Most human research relies on self-report, but individuals may not have good insight into their own emotions. We have developed a new way to identify emotional states using brain imaging and machine learning tools. First, we induced emotional states using film and music clips while individuals were in an MRI scanner. We trained a computer algorithm to identify the brain areas that distinguished 7 emotions from each other (fear, anger, surprise, sadness, amusement, contentment, and a neutral state). This procedure created a brain map for each of the 7 emotions. Then, a new group of participants self-reported their emotional state every 30 seconds in an MRI scanner while no stimuli were presented. We could predict which emotion was spontaneously reported by the subjects by comparing their brain scans to each of the 7 emotion maps. Finally, in a large group of 499 subjects, we found that the presence of the fear map during rest predicted state and trait anxiety while the presence of the sadness map predicted state and trait depression.

Low-Intensity Interventions Addressing Social Needs In Pediatric Settings Can Improve Child Health

MedicalResearch.com Interview with: Laura M. Gottlieb, MD, MPH Department of Family and Community Medicine, 2Center for Health and Community University of California, San Francisco MedicalResearch.com: What is the background for this study? What are the main findings? Response: Numerous studies have demonstrated that childhood exposures to social adversities, like family financial insecurity, food insecurity, and housing instability, lead to poorer health outcomes across the life course. These social adversities disproportionately affect low-income and racial minority populations. In response to this evidence there have been calls to address social needs in pediatric clinical care settings. For example, recently the American Academy of Pediatrics’ Task Force on Childhood Poverty endorsed the promotion of evidenced-based strategies to reduce the negative health effects of poverty on low-income children, including by increasing the availability of clinic-based interventions addressing social risks. In response to these calls to action, a growing number of pediatric health care organizations are screening for and address families’ social needs. There is a critical need for more evidence on the effectiveness of these types of interventions. Many of the studies conducted so far have focused primarily on assessing program process outcomes or impacts on families’ social needs, but have not evaluated actual health outcomes resulting from program participation. To our knowledge, this study was the first randomized clinical trial evaluating the impacts of a pediatric social needs navigation program on child health. The reported number of social needs identified at baseline ranged from 0 to 11 out of 14 possible items, with a mean [SD] of 2.7[2.2] needs identified by participating families. Family participation in the navigation program intervention significantly decreased families’ reports of social needs by a mean (SE) of .39(0.13) vs. an increase of a mean (SE) of .22(0.13) in the active control arm. Participation in the navigation program also significantly improved parent-reported overall child health, with a mean (SE) change of -.036(0.05), compared to the active control arm with a mean (SE) change of -0.12(0.05). At 4 months post enrollment, the number of social needs reported by those that participated in the navigation program decreased by a mean (SE) of .39(0.13). (more…)

Can Bartenders Have ‘Normal’ Home and Family Lives?

MedicalResearch.com Interview with: Emily H. Starr, M.A. Doctoral Candidate City, Culture, & Community Tulane University, New Orleans MedicalResearch.com: What is the background for this study? What are the main findings? Response: This study examines the relationship between work, partnering, and parenthood through the perspectives of bartenders working in the New Orleans metro area. Bartenders frame work, intimate relationships, and family as interlocking matrices and view their lack of legitimate work (or their lack of a normative 9-5 job with security, benefits, and a salary) as a prohibitive or complicating factor in their ability to assume the roles of partner and parent. Some of the fastest growing segments of the U.S. labor market are low-wage and low-skill jobs meaning that young people will increasingly grapple with hegemonic "white picket fence" ideologies that prescribe certain family forms and occupational/labor relationships as ideal. Moreover, the matrices of performative adulthood are gendered with women and men framing their work as incompatible with family life for different reasons. Women more often experience sexual harassment/objectification, feel their skills and abilities are called into question, and perceive that women bartenders are marginalized as "certain types of women." These perceptions lend themselves towards women bartenders framing barwork as incompatible or undesirable with mothering. Men express anxiety about their long-term earning potential and combating the stigma of low-status work through the professionalization of the craft cocktail and spirits industry. Thus, men are more concerned about their role as breadwinner rather than viewing bartending and fatherhood roles as mutually-exclusive. These findings suggest that bartenders draw upon dominant ideologies of normative adulthood and invoke traditional gender roles to frame their perspectives about bartending and family life. Importantly, the contours and realities of their working lives are the prohibitive factor in bartenders' perspectives about the possibility for participating in long-term intimate relationships and parenthood.

Higher Minimum Wage Associated With Fewer Small Babies and Neonatal Deaths

MedicalResearch.com Interview with: Kelli A. Komro, MPH, PhD, Professor Director of Graduate Studies Behavioral Sciences and Health Education Jointly Appointed, Epidemiology Rollins School of Public Health Emory University Atlanta, GA 30322 MedicalResearch.com: What is the background for this study? Dr. Komro: Epidemiologists have done a thorough job describing the income-health gradient, which shows a clear association between income and health. That is, as income increases, exposure to health risks and premature mortality decreases. Each step down on the income ladder decreases one’s health for many reasons related to material resources, physical environment exposures and social circumstances. The income to health association begins at birth, and more than one in four women giving birth in the U.S. are below the poverty level, putting nearly 1 million babies at risk each year. Low-income mothers are more likely to give birth prematurely, to have low birth weight babies, and to suffer the death of their infant during the post-neonatal period (28 to 364 days old). Given the importance of the income-health gradient, we set out to test the health effects of policies that are designed to increase economic security among low-income families. Our main question is: Do policies designed to reduce poverty and improve family economic security also improve health? One relevant policy is minimum wage laws. A federal minimum wage was first enacted in 1938. The real value (in 2015 dollars) of the federal minimum wage reached a high of $10.85 in 1968. The current federal rate is $7.25. Many cities and states have passed minimum wage laws that are higher than the federal rate, and currently there is a range of minimum wage increases under active public and policymaker discussion. Given that some states pass minimum wage standards and others do not, and that laws within states change over time, we took advantage of all the changes that have occurred to design a natural experiment. Our natural experiment examined the effects of state minimum wage laws on infant health. (more…)

Father’s Lengthy Work Commute Linked to Emotional Distress in Children

MedicalResearch.com Interview with: Dr. Jianghong Li, Senior Scientist (PhD) From the President’s Project Group, WZB Berlin Social Science Center (Wissenschaftszentrum Berlin für Sozialforschung GmbH: www.wzb.eu) Reichpietschufer 50, 10785 Berlin, Germany MedicalResearch.com: What is the background for this study? Dr. Jianghong Li: Commuting to work is a common phenomenon in developed countries. In the US full-time wage workers residing in urban counties on average commuted about 55 minutes to work. In the UK, workers commuted 42 minutes (round trip) for work in 2008. German workers commute 13 kilometers and 44 minutes both ways to work on average. The average daily commuting time for work in other European countries ranges from 29 minutes in Portugal to 51 minutes in Hungary. To make your commute a little easier, why not try the Moovit app with its handy tracking tools such as the metro map. Men commute longer than women to work and working fathers commute further to work than working mothers. Men who are employed full-time and with children commute longer than their counterparts without children, regardless of the age of the youngest child. Previous research has shown that long commuting to workplace is associated with reduced civic participation and social interactions, lower life satisfaction, elevated stress hormone and reduced task performance, and increased risk for marriage breakdown. Daily experiences of unreliable transport, conflicting time schedules, congested roads and crowded trains contribute to commuters’ physical and psychological stress. These health and psychosocial consequences of commuting raise a concern about its plausible negative impact on children’s well-being. Yet, there was no inquiry about the effect of commuting on children’s well-being, except one small-scale study in the US of mothers leaving welfare for employment. (more…)

Many Caregivers Report High Levels of Depression and Loss of Control Over Their Lives

MedicalResearch.com Interview with: Jill Cameron, PhD Canadian Institutes of Health Research New Investigator Associate Professor, Department of Occupational Science and Occupational Therapy Rehabilitation Sciences Institute Faculty of Medicine, University of Toronto MedicalResearch.com: What is the background for this study? What are the main findings? Dr. Cameron: In the world of critical illness, a lot of research has focused on helping people to survive – and now that more people are surviving, we need to ask ourselves, what does quality of life and wellbeing look like afterwards for both patients and caregivers? The aim of our research was to identify factors associated with family caregiver health and wellbeing during the first year after patients were discharged from the Intensive Care Unit. We examined factors related to the patient and their functional wellbeing, the caregiving situation including the impact it has on caregivers everyday lives, and caregiver including their sense of control over their lives and available social support. We used Pearlin’s Caregiving Stress Process model to guide this research. From 2007-2014, caregivers of patients who received seven or more days of mechanical ventilation in an ICU across 10 Canadian university-affiliated hospitals were given self-administered questionnaires to assess caregiver and patient characteristics, caregiver depression symptoms, psychological wellbeing, and health-related quality of life. Assessments occurred seven days and three, six and 12-months after ICU discharge. The study found that most caregivers reported high levels of depression symptoms, which commonly persisted up to one year and did not improve in some. Caregiver sense of control, impact on caregivers’ everyday lives, and social support had the largest relationships with the outcomes. Caregivers’ experienced better health outcomes when they were older, caring for a spouse, had higher income, better social support, sense of control, and caregiving had less of a negative impact on their everyday lives. No patient characteristics or indicators of illness severity were associated with caregiver outcomes. Poor caregiver outcomes may compromise patients’ rehabilitation potential and sustainability of home care. Identifying risk factors for caregiver distress is an important first step to prevent more suffering and allow ICU survivors and caregivers to regain active and fulfilling lives. (more…)

When It Comes To Sexual Satisfaction Between Partners, Gut-Level Responses May Be Most Accurate

MedicalResearch.com Interview with: Lindsey Hicks Doctoral Student Social Psychology Florida State University MedicalResearch.com: What is the background for this study? What are the main findings? Response: My colleagues and I are very interested in the factors that differentially predict peoples’ self-reported relationship satisfaction and their gut-level feelings about their partners—the spontaneous feelings they have and may not articulate. Because explicit self-reports require conscious deliberation they are subject to the influence of biases and beliefs about relationships; gut-level, automatic attitudes do not require conscious deliberation and thus appear to better track actual experience. With that in mind, we examined whether sexual frequency influences automatic but not explicit evaluations of the partner. Previous research has yielded inconsistent results regarding the influence of sexual frequency on relationship satisfaction, and we thought such inconsistencies may stem from the influence of deliberate reasoning and biased beliefs regarding the sometimes taboo topic of sex. Thus, we tested the association between partners’ sexual frequency and their gut-level feelings about each other. Basically we found that the frequency with which couples have sex has no influence on whether or not they report being happy with their relationship, but their sexual frequency does influence their more spontaneous, automatic, gut-level feelings about their partners. This is particularly important in light of previous research done by my colleagues demonstrating that it these automatic attitudes ultimately predict whether or not they’ll end up becoming dissatisfied with their relationship.

Street Children Report Poverty, Family Conflict, and Abuse as Reasons For Their Homelessness

MedicalResearch.com Interview with: Paula Braitstein, PhD Division of Epidemiology, Dalla Lana School of Public Health, University of Toronto, Toronto, Ontario, Canada Department of Medicine, College of Health Sciences, School of Medicine, Moi University, Eldoret, Kenya Department of Epidemiology, Fairbanks School of Public Health, Indiana University, Indianapolis Regenstrief Institute Inc, Indianapolis, Indiana MedicalResearch.com: What is the background for this study? Dr. Braitstein: There are vast numbers of children and youth in the world who find themselves in street circumstances. Yet, there is an absence of consensus among academics, policymakers, stakeholders, and international organizations regarding the causes of child and youth street-involvement around the world. Without data concerning these reasons, policies are developed or implemented to mitigate street-involvement without taking these causes into account. Often, the prevailing paradigm assumes that children and youth on the street are juvenile delinquents and the government response is often characterized by social exclusion, criminalization, and oppression by police and civic authorities. Therefore we wanted to find out what reasons do children and youth self-report for their street-involvement globally. MedicalResearch.com: What are the main findings? Dr. Braitstein: We systematically reviewed the literature and compiled data from 49 studies representing 24 countries globally. Street-connected children and youth most frequently reported poverty, family conflict, and abuse as their reasons for street-involvement. They infrequently identified delinquent behaviours for their circumstances. There were no significant differences between males and females reported reasons, with the exception of females in developed regions who were more likely to report abuse. (more…)

Strong Men Given Higher Status By Others In Hopes of Group Gain

MedicalResearch.com Interview with: Aaron W. Lukaszewski, Ph.D. Assistant Professor Department of Psychology Oklahoma State University Medical Research: What is the background for this study? What are the main findings? Dr. Lukaszewski: A large body of evidence from multiple social science fields indicates that physically formidable men tend to attain positions of leadership and prestige within cooperative groups (e.g., communities, businesses, nations). The most common explanation for this phenomenon is that strong men ascend hierarchies by aggressively intimidating their rivals and fellow group members into submission -- much like chickens use physical contests to establish "pecking orders" that define rank. The current research advances a different explanation for why formidable men attain high status. Specifically, we propose that members of cooperative groups willingly confer high status upon physically strong men, because they are perceived as possessing specific leadership capacities. To test this, we had people view photographs of men and women whose physical strength had been previously measured, and evaluate them along specific dimensions. As predicted, stronger men (but not women) were seen as deserving higher status, and this was explained by the fact that such men were seen as being better leaders (as defined by their apparent ability to enforce group policies and represent the group to outsiders). Moreover, physically strong men who were seen as being likely to aggressively intimidate others were projected to acquire less status than their apparently gentler counterparts. Taken together, the findings support the idea that strong men are given higher status by others because they are perceived as being likely to use their strength to benefit the group by cost-effectively providing valuable leadership services.

Increased rates of incarceration may mean more sexual partners and STDs

MedicalResearch.com Interview with: Andrea K. Knittel, MD, PhD PGY-3, Department of Obstetrics, Gynecology, and Reproductive Sciences University of California, San Francisco Medical Research: What is the background for this study? Dr. Knittel: The United States has the highest rate of incarceration in the world, and many studies have shown that involvement in the criminal justice system may be a risk factor for HIV/AIDS or other STDs. For example, some studies have found that in areas with high rates of incarceration, rates of STDs are higher, and others have shown that incarcerated individuals are more likely to have higher rates of concurrent sexual partnerships and a greater number of sexual partners. This may happen because of increased rates of partnership dissolution due to physical and emotional distance, as well as a desire on the part of formerly incarcerated men for an increased number of sexual partners to “make up for lost time,” which some studies have suggested. In addition, the female partners of incarcerated men may rely on other relationships, including new sexual partners, for emotional and financial support while their partners are incarcerated, whether their relationships end permanently or temporarily or they maintain their relationships through visits and calls. Very few studies have been able to look at community level effects of incarceration, however, because it is difficult to gather data at this level. This study uses an agent-based model, a computational approach that provide a closed system in which to test hypotheses. An agent-based model is a computer simulation that creates a small community (250 “agents” or simulated people) in which the agents can date and have sexual relationships. The model used in this paper has been shown previously to be similar to young people in the US. The experiment in this study was to run the model without incarceration and see how many partners men and women in the community had, and then add incarceration into the model and see what happened. Based on data from other studies, when men in the model were incarcerated they had a slightly higher risk of ending a relationship and became slightly less desirable as partners. (more…)

States That Spend More On Social Services Have Lower AIDS Deaths

MedicalResearch.com Interview with: Kristina Marie Talbert-Slagle, PhD Lecturer in Epidemiology (Microbial Diseases) and in Public Health (Health Policy); Senior Scientific Officer, Yale Global Health Leadership Institute Yale School of Public Health Medical Research: What is the background for this study? What are the main findings? Dr. Talbert-Slagle: The interest for this study originally came as a result of work done by Elizabeth Bradley, PhD, co-author of The American Health Care Paradox. In the book, Dr. Bradley compared spending rates of social services to health care services between the U.S. and other countries and found that while the U.S. invested more money in health care services than any other country we had worse health outcomes. By contrast, countries that spent more on social services per dollar spent on health care had better outcomes. We applied that same idea to AIDS. There are still more than 50,000 cases of HIV/AIDS diagnosed in the U.S. each year. Although many medical advances have been made in treatment and prevention of this infection, we were curious as to why rates of HIV/AIDS have remained stagnate. We wanted to explore how spending relates to differences in case rates among the states and found a significant difference among states regarding social service and public health spending related to HIV/AIDS. We looked at all 50 states’ spending habits over the past 10 years and discovered that states that invested more money in social services such as education, housing, and nutrition per person in poverty had significantly lower rates of HIV/AIDS deaths.

Video Interaction Project Improved School Readiness In Impoverished Children

MedicalResearch.com Interview with: Alan Mendelsohn, MD Associate professor, Departments of Pediatrics and Population Health Adriana Weisleder, PhD Research scientist, Department of Pediatrics NYU Langone Medical Center Medical Research: What is the background for this study? What are the main findings? Response: In the last decade, scientists have begun to understand the mechanisms by which poverty can cause changes in brain development that can lead to higher rates of behavior problems and lower educational achievement for disadvantaged children. This study shows that pediatric-based programs that promote reading aloud and play can help prevent these problems before they arise. The Video Interaction Project (VIP) – the main program studied in the research – takes place at regular pediatric check-ups starting at birth. A trained parenting coach meets with the family at each visit and records the parent and child playing and reading together with materials provided by the program. The coach then reviews the video with the parent to identify and reinforce positive interactions and encourage strong parent-child relationships. The second intervention program, Building Blocks, is a lower-intensity option in which families receive parenting pamphlets and learning materials monthly by mail to facilitate reaching specific developmental goals. The results of the three-year randomized-controlled trial showed notable benefits for children’s social and emotional development. Children of families who participated in the Video Interaction Project had better attention and play skills as toddlers and reduced hyperactivity and aggression at three years, compared to children in a control group. For the highest risk families, hyperactivity was reduced by more than half. These findings are important because a child’s ability to control or regulate his or her behavior is a critical factor in their learning and success at school. (more…)
