Predict My Future reveals the answers to one of life's most fundamental questions: what makes us who we are? 43 years ago a New Zealand medical school embarked on a remarkable project—the ultimate nature versus nurture test. They decided to follow every one of the 1,037 babies born in the city of Dunedin between April 1972 and March 1973 for their entire lives. And they have. Those children have become the 1,000 most studied people in the world.
For almost four decades every aspect of their health and development has been monitored—their genes, their growth, their physical well-being, their psychology, their emotional ups and downs, criminal convictions, successes, failures—the lot. The result is the Dunedin Longitudinal Study, the broadest and the most in-depth study of human beings in the world. The project has become the richest and most productive archive of human development anywhere. It is truly unique; the study has retained an unprecedented 96% of its starting participants. It is re-writing the book on what makes us all human. Predict My Future details the study's findings, and explores what they have to say about all our lives. This series has a global audience and is being screened across Europe, and in Australasia, with additional territories in negotiation.
Join us for a screening of the first installment of the four-part documentary in the Connection at SSRI. Lunch will be provided and gourmet cotton candy will be spun on site.
Professor Terrie Moffitt, associate director of the study, will introduce the documentary and stay for a Q&A after the showing.
Please let us know if you can join us. View the invitation and RSVP here. What: Predict My Future

Dear DUPRI Colleagues,
I am touching base with you all as we approach the end of the spring semester to bring you up to date on all that has been happening with DUPRI and its affiliated centers this year. DUPRI is a network of cooperating centers that shares staff and spatial resources in association with the Social Science Research Institute (SSRI). The core centers in this network include the Center for Population Health and Aging, the Duke Network Analysis Center, and the Duke Center for Population Research, but each has other affiliated centers as well. Each core center has distinctive intellectual aims and research needs, but many faculty have overlapping memberships across these centers. The bases for these overlapping memberships include common interests in excellence and scientific impact in (1) research on the social bases of physical and mental health across the lifespan and across social contexts; (2) innovative data collection and analysis strategies to enrich our knowledge of lives across time and space; and (3) training and mentorship of the next generation of population scientists.
Much work has been done in the last two years to secure the scaffolding of our networked organization of population scientists. Our primary efforts have been directed at winning university and federally funded support for the DUPRI center infrastructure (principally staffing and programmatic space). The NIA P30 center grant awarded September 2014 to the Center for Population Health and Aging (CPHA) is the first weight-bearing component of this scaffolding. The second to be reviewed at NICHD shortly is the PRC grant proposal for a general population dynamics center called the Duke Population Research Center (DPRC). The third is the Duke Network Analysis Center (DNAC) that is pending award as a NIH R25 center. We have received university support directly from the Dean of Arts & Sciences and the Provost office and indirectly from the Provost through the Social Science Research Institute. This support has come (with more to come conditional on funding) as direct support for staff, programming and new space.
DUPRI also responded to the SSRI $250k Challenge for innovative proposals for data analysis this Spring and has been recognized to move to a second round of discussions with the DUHS to establish a Duke infrastructure to support regular mechanisms for collaboration between population scientists and DUHS through access to medical center databases and collaborations on clinical research projects. This negotiation is in progress. You will be invited to participate in this process, with an initial meeting on Monday April 27th (the announcement has been transmitted to you). This promises to be a long-term signature program for population science at Duke. It will probably take the next half year to develop such an infrastructure, but we have the active attention of Medical Center folks and we ask for your involvement in the months to come.
Currently, we are working to submit a continuation of the NIA supported T32 training grant supporting doctoral and postdoctoral students in the social and economic demography of aging, which we have had for over 25 years. If you have been invited to become involved in this effort (which faces a May 25, 2015 deadline), please respond. If you are interested in being involved, please contact DUPRI.
Finally, woven through all these efforts has been a robust emergent collaboration with UNC-Chapel Hill’s Carolina Population Center. You have probably noticed announcements of jointly sponsored seminars and speakers. NIH funding has already resulted from this collaboration. Our hope is that more collaboration will come in the future.
This has all been possible because Duke has a productive and growing network of scientists making groundbreaking contributions in population studies, not only on human populations but also primate populations, at the ecological, social and molecular levels.

Ryan Brown, an economics doctoral candidate in DuPRI’s National Institute on Aging-funded training program, has received the Minnesota Population Center's 2012 IPUMS-USA Research Award for the "best published or unpublished work by a graduate student." His paper titled, "On the Long Term Effects of the 1918 U.S. Influenza Pandemic," is based on the Center's U.S. Census microdata series and was unanimously selected by the MPC panel for the recognition.
Brown's as yet unpublished study, written with Economics professor and DUPRI Fellow Duncan Thomas, examines the socioeconomic backgrounds of the cohort of U.S. children who were in utero during the flu pandemic of 1918-1919 and tests a theory that these kids suffered particular hardships, even into old age, as a result of that early-life exposure. The paper shows how challenging a single assumption in a prior analysis can alter its results dramatically.
Brown's paper was not an attempt to challenge the idea that early-life exposures can cause permanent harm, he cautions, but rather a reminder to fellow economists that, "We need to think really hard about how we go about using natural experiments. It's really important to have strong theory behind it, and to take your assumptions very seriously, because they are that, they are assumptions."
In 2006, amid heightened concern over the possibility that a new strain of avian influenza could morph into a global human flu pandemic to rival the Great Influenza, Columbia University economist Douglas Almond published his analysis showing the lifelong disadvantages experienced by the babies born in the U.S. during and just after the 1918-1919 crisis. They had fewer years of education, earned less as adults and had more disability late in life.
Evidence from biology and epidemiology strongly supports the idea that prenatal exposures—whether to exogenous chemicals, disease or other forms of maternal stress—can impact a developing fetus in ways that may harm its health and fitness for a lifetime. And a growing body of research suggests that such developmental deficits can lead to real social and economic losses.
Almond argued that the 1918 pandemic was an ideal natural experiment for identifying these long-term consequences of an early exposure because the flu infected about a third of the U.S. population, including a slightly higher proportion of pregnant women. The pandemic came on suddenly, lasted for a relatively short and clearly defined period, and its spread appeared to be geographically random—no part of the nation was spared.
Brown and Thomas have shown, however, that the fate of being a fetus during the great pandemic was anything but random. They write: "A key assumption underlying [Almond's study] is that the characteristics of the 1919 birth cohort are following the same linear trend as the surrounding birth cohorts."
In fact, the authors remind us, there was still a war going on at the time the flu hit in 1918, and in that era wealth and education made men more eligible for military service, not less so. An exemption from service for sole providers whose absence would cause severe financial hardship was more likely to favor the breadwinners of poorer families than those with ample resources. That meant the men left behind to potentially father children in 1918 were likely of lower socioeconomic status. Together with the fact that higher-status families are more prone and better able to delay childbearing during a period of crisis and uncertainty, Brown and Thomas argue that the family backgrounds of the 1919 birth cohort are a key variable to consider when examining their later-life outcomes.

Using data from the IPUMS samples of the 1920 and 1930 U.S. Censuses, they show "that those who were at highest risk of being exposed in utero were born to families of lower socio-economic status relative to the cohorts who were not exposed. Specifically, the fathers that produced a child in 1919 were significantly less likely to be WWI veterans, had jobs that produced less income, had lower socioeconomic status (SES), were older, had more total children, and were less likely to be white than fathers of those who were not at high risk of being exposed to influenza in utero."
As a result, they write of Almond's original analysis, "When including controls for childhood environment, the effect of in utero exposure on adult outcomes becomes small in magnitude and not statistically significant. Conclusions about the deleterious impact of in utero exposure to the influenza pandemic on socio-economic prosperity in adulthood are, at best, premature."
The issue, Brown says, is not that the 1919 cohort was particularly unlucky. On the contrary, "it's that they're just a different set of children, born to less well off parents, and when you compare them to the mixture [of children born before and after the pandemic], it makes them look bad. But when you compare them to a similar group by controlling for the parents' characteristics, it looks like they're doing just as well."
He and Thomas cannot speak to why the exposed cohort appear to be doing as well as the unexposed, and the authors are careful not to imply that being a pandemic baby had no ripple effects. But they conclude on a positive note that their findings at least suggest there is room for mitigating interventions later in life that could offset an early exposure.
Brown was drawn to Almond's paper because it was widely considered the strongest evidence of the potential for prenatal exposures to influence success throughout life. "And the topic itself is one I find incredibly interesting, the idea that things that can happen to us in utero can have such long-lasting and serious effects," he says. "I don't know if everyone is aware that's the case. We think a lot about helping the next generation, but I don't think we think about helping the next generation in utero.... It brings up a lot of interesting questions, so since this was the seminal work, I thought it was worthwhile to think deeply about it."
Brown credits mentoring by Thomas and DUPRI director Seth Sanders with "shaping the economist I am today" and instilling an appreciation for the importance of scientific rigor. Unlike the so-called hard sciences, he says, "We have to deal with a lot of confounding factors that there's no way to control, which does make social science a bit more challenging and brings back the issue of doing your best to look under every rock to make sure the assumptions you're making are valid."
His interest in natural experiments - and in testing their validity for answering specific questions - extends to another ongoing research project to examine the effects of maternal psychological stress on health outcomes for babies in utero during the terrorist attacks of September 11, 2001.
Brown, who will be working on completing his dissertation this summer and hitting the job market in the fall says of his IPUMS-USA Research Award, "Every time your peers say something you've done is worthwhile, and worth checking out, that means a lot. You work really hard on these things, and you really have your head down trying to get it right. It's nice when people you respect as your peers respect what you've done."
"Monkeys don't smoke, and they don't do yoga," says Jenny Tung. But monkeys do experience the kind of psychosocial stress that can drive humans to embrace both of those coping mechanisms. That's why Tung, an Assistant Professor of Evolutionary Anthropology and DuPRI Faculty Associate, believes monkeys are especially useful for shedding light on the ways that persistent stress can undermine human health.

In captivity, the rhesus macaques Tung is studying don't have to worry about predators, but they're all the more exposed to the constant harassment of higher-ranking individuals, who have all the power and never let subordinates forget it. For low-ranking animals, the inescapable bullying and lack of control exert the sort of chronic stress shown in the famous Whitehall Study of British civil servants to lead to an early death.
The fact that low status, whether at work or in society in general, greatly raises a human being's chances for heart disease, stroke and a range of other illnesses is well documented but still poorly understood. So Tung is embarking on a five-year study to try to get at some of the underlying mechanisms of those health effects. With a $2.8 million grant from the National Institute of General Medical Sciences, Tung and her collaborators will create new social groups of female macaques at the Yerkes National Primate Research Center in Atlanta, manipulate the animals' social hierarchy and use a range of molecular techniques to profile their gene activity and immune responses.SIGNATURES OF STRESS
In a preliminary project while she was a postdoctoral fellow at the University of Chicago, Tung found significant differences in gene regulation in the immune cells of female macaques depending on their social status—patterns so consistent that an individual's rank could be predicted with 80 percent accuracy based on her gene-expression profile alone. The results of that study, published in April, illustrate how stress-related hormones may signal immune cells to ready themselves for conflict, which the cells would do by raising or lowering the activity of certain genes. In the blood cells Tung examined, the biggest activity changes seen were in genes involved in inflammation and T-cell activation. Those processes help to fight infection, but are also implicated in heart disease and many other degenerative conditions.

The study also identified a possible mechanism for the gene-activity changes themselves. Methylation, the sequence of chemical groups along the surface of a DNA strand, constitutes a second "epigenetic" code involved in regulating which genes are activated and when. Tung's team identified clear signatures of rank in methylation changes near DNA regions involved in regulating the immune-related genes. One of Tung's goals in the new project is to explore whether any of the methylation changes associated with stress are long-lasting. There's already evidence that early-life stress can leave a permanent, even heritable, mark on DNA methylation. Noah Snyder-Mackler, a postdoc in Tung's lab who is currently looking at whether published signatures of social stress recapitulate those of aging, will examine the same question for the methylation changes associated with rank in macaques.
"We, like a lot of investigators at DuPRI who come from different directions, are interested in life history, health over the life course," says Tung. "Which is for [non-human primates] 'fitness'… Survival and health and reproduction are really where the rubber meets the road as far as fitness, and how social interactions affect differences in how individuals age over the life course, and how stress accumulates to influence those kinds of outcomes." Tung adds that she sees a lot of potential for cross-disciplinary work in genomics and aging. "We actually have a lot of shared questions, we just come at it from different angles."
A cross-species perspective was central during Tung's postdoc in Yoav Gilad's laboratory at the University of Chicago. Gilad, who is in the Department of Human Genetics, focuses on comparing primate genomes to understand gene-regulatory mechanisms and evolution. And, according to Tung, being around so many people doing human genetics work inspired ideas for getting the most out of the preliminary macaque study, many of which will carry over into the new project. In addition to looking at DNA methylation, the team examined the composition of immune cells in the monkeys' blood, to see whether certain types of cells were increasing or decreasing in response to stress. That also let them account for the possibility that apparent gene activity changes in a given cell type were the result of there being more of that type of cell present. In the new study, Tung and her colleagues will be measuring gene expression through RNA sequencing, which will let them look not just at the level of activity by a particular gene, but also whether its RNA is being "spliced" in alternative versions under different stress conditions.
Finally, Tung and her collaborators want to see how all these gene-activity changes might translate into a direct effect on health by challenging the monkeys' immune systems. Rather than exposing the animals to pathogens, though, the team will draw blood from the 10 highest-ranking and 10 lowest-ranking macaques directly into test tubes laced with antigens that immune cells recognize as parts of viruses or bacteria. This will allow them to capture the sets of genes that respond to a challenge, the magnitude of the response and identify which aspects of immunity (innate, adaptive, etc.) are influenced by dominance-rank effects.GENE-BEHAVIOR DIALOGUE
Tung completed her Ph.D. in Biology at Duke in 2010, under the direction of Gregory Wray and Susan Alberts, and she hopes to continue work she started as a graduate student investigating subtle changes among wild baboons in Kenya's Amboseli National Park. The original population of yellow baboons there is now intermingled with a different subspecies, and Tung, who just returned from Kenya in July, is interested in how that admixture and hybridization affects maturation and mating behavior in the group. The baboon studies with Alberts "focus on longitudinal work, mostly observational, but also genetics," Tung says, "so the data are behavioral and social and demographic, with similarities to the types of data that some of the investigators at DUPRI collect" on people. With non-human primates, though, it's easier to eliminate some of the "noise," she explains.
Rhesus macaques at Yerkes, copyright Yerkes National Primate Research Center."One of the problems with humans is to demonstrate causality. Is the gene expression coming first or the social environment coming first?" Tung says. "We want what we're doing to be relevant to humans, so it's really helpful to do the parallel studies in humans, but doing them in macaques first establishes that social environment seems to have an effect as best we can assess." The social environment for a rhesus macaque is complex but a lot simpler than it is for humans. Especially in modern society, people are "interfacing with a lot of different individuals, depending on the day or time of day or context," according to Tung. So a person might be high-status at work, but berated at home, making it hard to characterize the influence of social status. "The other thing we can do with nonhuman primates is watch them all the time," Tung notes.
In the new experiment, Snyder-Mackler is also interested in seeing whether the low-ranking monkeys adopt any behavioral patterns to help them cope with stress. "Social support is relevant for nonhuman primates, and some of the work my colleagues have done on baboons, for instance, has suggested that survival probabilities are affected by the strength of social bonds," Tung says. "That's mediated by grooming and proximity, also if someone is stressing you out, you should probably get away from them." The macaques at Yerkes will be divided into 10 social groups of five animals each, so it might be hard for an individual to avoid harassment from another of higher rank. For that reason, Tung thinks the investigators might get "a particularly clear signal" of social stress. "In a naturally constituted group, you might have more kin support to help offset that kind of harassment, just by being there or forming coalitions to dissuade that kind of behavior," she says.
If there's a theme to the Tung lab's work, it is adaptation - genetic and behavioral - to changing circumstances. "All of us are interested in the relationship between behavior and social structure and social structure and genes and the genome, and we pursue it in a lot of different ways," Tung says. "I have always worked on primate genetics in the context of evolution, so it's a natural fit. It's the sort of research that bridges between biology and evolution and aspects of behavior and genetics and evolutionary anthropology, so it doesn't seem like a stretch."

Jenny Tung, Faculty Associate at DUPRI and an Assistant Professor in the Department of Evolutionary Anthropology, has been awarded a five-year R01 grant from the National Institute of General Medical Sciences totaling $2.8 million to study changes in gene regulation in response to psychosocial stress among rhesus macaques. As a model for the human experience of chronic stress, Tung says the macaques' gene responses may shed light on mechanisms underlying some of the well-documented health effects linked to stress in people.
In a preliminary project while at the University of Chicago, Tung and her colleagues showed significant differences in gene activity in the immune cells of female macaques depending on their rank within the social group—patterns so consistent that an individual's rank could be predicted with 80 percent accuracy based on her gene-expression profile alone. The new work, to be conducted with macaques at the Yerkes National Primate Research Center, will further examine genetic and epigenetic changes linked to rank-associated stresses as well as differences in how the animals' immune systems respond to challenge. Collaborators will include Zachary P. Johnson and Mark E. Wilson at Yerkes and Luis B. Barreiro at the University of Montreal. Tung, who earned her PhD in Biology at Duke in 2010, completed a postdoctoral fellowship in the laboratory of Yoav Gilad in Chicago and recently returned to Duke to form her own lab.
