Physical Activity Across The Lifespan And Liver Cancer Incidence In The Nih-Aarp Diet And Health Study Cohort., Hannah Arem, Erikka Loftfield, Pedro F Saint-Maurice, Neal D Freedman, Charles E Matthews

Epidemiology Faculty Publications

While liver cancer rates in the United States are increasing, 5-year survival is only 17.6%, underscoring the importance of prevention. Physical activity has been associated with lower risk of developing liver cancer, but most studies assess physical activity only at a single point in time, often in midlife. We utilized physical activity data from 296,661 men and women in the NIH-AARP Diet and Health Study cohort to test whether physical activity patterns over the life course could elucidate the importance of timing of physical activity on liver cancer risk. We used group modeling of longitudinal data to create physical activity …

Rural And Urban Injection Drug Use In Puerto Rico: Network Implications For Human Immunodeficiency Virus And Hepatitis C Virus Infection, Courtney Thrash, Melissa L. Welch-Lazoritz, G. Robin Gauthier, Bilal Khan, Roberto Abadie, Kirk Dombrowski, Sandra Miranda De Leon, Yadira Rolon Colon

Department of Sociology: Faculty Publications

Understanding the short- and long-term transmission dynamics of blood-borne illnesses in network contexts represents an important public health priority for people who inject drugs and the general population that surrounds them. The purpose of this article is to compare the risk networks of urban and rural people who inject drugs in Puerto Rico. In the current study, network characteristics are drawn from the sampling “trees” used to recruit participants to the study. We found that injection frequency is the only factor significantly related to clustering behavior among both urban and rural people who inject drugs.

Coffee Drinking And Leukocyte Telomere Length: A Meta-Analysis, Bella Kotlyar

Yale Day of Data

Telomeres are long tandem nucleotide repeats responsible for maintaining chromosomal integrity. They shorten with each cell division, serving as markers for cellular aging and replicative ability, and shorter telomere length has been associated with greater risk of various chronic diseases of aging. There is increasing interest in the relationship between telomere length and lifestyle factors, such as components of the diet, that are associated with age-related chronic diseases, like cancer and diabetes.

There is mounting evidence that coffee, one of the most commonly consumed beverages in the world, has potential protective effects against chronic disease and mortality. Few studies have …
