  1. Fulltext. Neighborhood risk factors for low birthweight in Baltimore : A multilevel analysis.

    Article - En anglais



    Past research on low birthweight has focused on individual-level risk factors.

    We sought to assess the contribution of macrolevel social factors by using census tract-level data on social stratification, community empowerment, and environmental stressors.


    Census tract-level information on social risk was linked to birth certificate records from Baltimore, Md, for the period 1985 through 1989.

    Individual-level factors included maternal education. maternal age, medical assistance health insurance (Medicaid), and trimester of prenatal care initiation.

    Methods of multilevel modeling using two-stage regression analyses were employed.


    Macrolevel factors had both direct associations and interactions with low birthweight.

    All individual risk factors showed interaction with macrolevel variables ; that is, individual-level risk factors for low birthweight behaved differently depending upon the characteristics of the neighborhood of residence.

    For example, women living in high-risk neighborhoods benefited less from prenatal care than did women living in lower-risk neighborhoods.


    Multilevel modeling is an important tool that allows simultaneous study of macro-and individual-level risk factors.

    Multilevel analyses should play a larger role in the formulation of public health policies.
