This population-based prospective cohort study was initiated in 1996, in which ~75,000 Chinese women living in Shanghai were recruited from 1996 to 2000. In addition to survey data, most study participants donated a blood or mouthwash sample and a urine sample at baseline. This cohort of women is being followed for incidence of site-specific cancers and cause-specific mortality. Five in-person follow-up surveys have been completed, each with a response rate greater than 90%. The resources from this study have supported more than 200 studies, including approximately 40 international research consortia, to address etiologic hypotheses for cancers and other chronic diseases. The SWHS, with its large sample size, wealth of resources, unique exposure patterns, and disease spectrum, provides exceptional opportunities to address many significant hypotheses that cannot be adequately investigated in other existing cohorts.

The SCCS was initiated in 2001. Nearly 86,000 adults aged 40-79 at cohort entry were recruited during 2002-2009 across 12 southern states, mostly at Community Health Centers (institutions providing basic health and preventive services in underserved areas). By design, two-thirds of the cohort was selected to be African American and the remainder predominantly non-Hispanic white to help remedy the underrepresentation of African Americans in health studies and enable direct black/white comparisons. Most of the cohort members, both black and white, had low income and education levels. In addition to detailed survey data, biospecimens were collected from more than 76,000 cohort members at baseline, with blood obtained and stored for approximately 39,000, mouth rinses/saliva for 38,000, and urine for 24,000, so that genomic DNA could be extracted from nearly 90% of participants. In 2018, we initiated stool sample collection and have collected these samples from ~8,500 cohort members. This cohort is being followed for incidence of site-specific cancers and cause-specific mortality. Data and biospecimens collected in the SCCS have been used to support large numbers of epidemiologic and genetic studies of cancer and other chronic diseases.

We will use a combination of human natural quasi-randomization studies of infant RSV infection specifically designed to assess the impact of infant RSV infection on subsequent respiratory health and the airway epithelium, and in vitro models of RSV infection of nasal airway epithelial cells (NAECs). The overarching objectives of the 3 aims that will test these hypotheses are: 1) to determine whether the age of first infant RSV infection is associated with risk of subsequent incident recurrent wheeze and asthma; 2) to delineate the longitudinal effects of RSV on airway epithelial cell differentiation and metabolism throughout infancy and childhood; 3) to evaluate host gene infant RSV infection interactions and RSV-dependent NAEC DNAm longitudinally to identify changes and temporal stability of RSV-dependent DNAm marks and their association with recurrent wheeze and asthma.
