  • Spring 2015 Progress Report on DuPRI | DuPRI
    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

  • DuPRI Faculty Spotlight: Anatoliy I. Yashin, PhD. | DuPRI
    about those who made it to very old age that allowed them to keep on going Vaupel had already devised the concept of individual frailty to describe such an intrinsic quality whether an aspect of the environment or an inherited predisposition for example that would influence a person s lifespan To examine this quality in the oldest old more closely they needed a model that could tease apart the genetic and environmental influences on longevity in individuals They also needed a lot of data on twins Yashin and Vaupel began working with Danish registry data and eventually moved their operation to the University of Southern Denmark in Odense to work on determining which aspect of individual frailty genes or environment is more important to lifespan The correlated frailty model Yashin developed there with PhD student Ivan A Iachine in 1995 remains widely used today by researchers trying to parse the relative influences of genes and environment Applied to Scandinavian twins it offered Yashin and Vaupel the surprising finding that genes were fairly unimportant to longevity perhaps 25 percent of the picture Genes though could explain about 50 percent of the differences in frailty between individuals The intriguing result also begged a new set of questions with or without fortunate genes what had the very old done or exposed themselves to or avoided during their lifetimes that might account for their survival INTERCONNECTED SYSTEMS By 1996 Vaupel and Yashin were at the MPIDR in Rostock Germany and shifting their focus to the interactions between genes and environment over a lifetime that might shed light on extreme longevity They realized that longitudinal studies could provide the kind of long term data on health histories and mortality they would need but wouldn t contain everything required to understand the life course of individuals We understood that in order to study aging we should take into account the wealth of knowledge about aging and lifespan that is accumulated in the field Yashin says It is not represented in specific data but people have found connections between phenomena of aging for example stress resistance tends to decline with age which means that the same stress that could be tolerated when we were young could be very dangerous when we re old Similarly important he adds are adaptive capacity the body s ability to adjust its functioning in response to stressors as well as so called allostatic load essentially the burden of chronically making those adjustments The quadratic hazard model Yashin developed to incorporate those kinds of unobserved variables along with longitudinal data made it possible to analyze a much richer picture of the forces influencing health and lifespan With this new approach Yashin and his colleagues have demonstrated the importance of stress and other exposures on how we age and even found evidence for the controversial phenomenon of hormesis the idea that a little bit of stress even in the form of a toxin can produce beneficial effects in the body The model also allowed

  • DuPRI Faculty Spotlight: M. Giovanna Merli, Ph.D. | DuPRI
    China particularly in cities has led its people to acquire a new sense of privacy Merli explains They don t feel they need to appease local authorities so they refuse to answer questions They re pretty much behaving like the U S population now Merli right with an employee at the Shandong Province Rural Family Planning Station 1995 Nonetheless in 2007 2008 Merli and her collaborators at the Fudan University School of Public Health accomplished the first ever survey of local sexual networks in China The Shanghai Sexual Behavior and Sexual Networks Survey asked a population representative sample of 1 600 men and women in that city of 19 million about their sexual activity and partners as well as their reproductive preferences Responses to the sexual behavior questions were fed into the network simulations Moody and Merli generated to model potential HIV spread And Merli used the participants answers about their reproductive ideals to examine what might happen if China lifted its controversial one child policy established in 1979 When the family size restrictions were first announced they were only supposed to last a generation Now more than 30 years later as scholars and politicians debate whether to rescind the decree a generation of singleton kids are themselves getting married and making choices about having a family In a 2000 study based on early 1990s data Merli found that birth rates among rural Chinese families were low but slightly higher than official reports claimed in part due to underreporting of female babies born to families trying for a son Merli argued that these girls were likely hidden with the knowledge of local officials charged with enforcing the one child policy and motivated to meet their quotas Still a subsequent examination of the same data set in 2002 showed that in some rural areas the one child policy had not only succeeded overall in changing reproductive behavior but had also started shifting personal preferences toward having fewer children In the December 2011 issue of Population Merli makes the case that based on her more recent Shanghai survey sample the shift in fertility preferences at least in Chinese cities is sincere and grounded in a new individualism and consumerism that have little to do with official fertility policy Her respondents professed in many cases to be content with a single child or two at most They often cited reasons like the expense lifestyle constraints and career costs of large families that will ring familiar in other nations where fertility rates have fallen naturally as prosperity rose TOOLS OF THE TRADE Though the Shanghai residents in the larger sexual networks survey were selected through standard census based probability driven sampling techniques Merli s sex worker survey used a recruitment approach gaining popularity for reaching people in the shadowy margins of society Respondent Driven Sampling relies on an initial group of survey respondents to invite select associates to participate with the chain of referrals revealing an ever larger sample of the target population The
