Objectives: To investigate the extent to which spatial social polarization is associated with preterm birth among urban African-American and non-Latinx white women, and whether prenatal care modifies this relationship.

Results: Women who resided in the bottom ICE quintile neighborhoods had a preterm birth rate of 11.

Context: As response rates to health surveys conducted by telephone continue to decline and costs continue to increase, practitioners are increasingly considering a transition to self-administered mail contact modes.

Objective: To compare empirical differences observed across adjacent administrations of the Healthy Chicago Survey (HCS) conducted by telephone versus self-administered via mail contact.

Design: Data from the 2016, 2018, and 2020 administrations of the HCS are contrasted, and demographic distributions are benchmarked against the American Community Survey to investigate differences that may be linked to the HCS' transition from a telephone to self-administered mail mode between 2018 and 2020.

Objective: Among HIV-infected persons, we evaluated use of client partner notification (CPN) and health-department partner notification strategies to inform sex partners of possible HIV exposure, and prior exposure to partner counseling and referral services.

Methods: We conducted a cross-sectional, observational study of 590 persons diagnosed with HIV in the prior 6 months at 51 HIV test, medical, and research providers in Chicago and Los Angeles in 2003 and 2004. Logistic regression was used to identify independent correlates of using CPN to notify all locatable partners.
