Study authors, "conducted a household survey of 8782 adults residing in 343 Chicago, Illinois, neighborhoods to assess mean levels of perceived social support and used U.S. Census data to estimate neighborhood economic disadvantage."

After adjustment for individual-level risk factors, this difference was reduced to 154 g," reported S.L. Buka and coauthors, Harvard University, School of Public Health.
