Measuring progress in meeting healthy people goals for low birth weight and infant mortality among the 100 largest cities and their suburbs

Abstract

We examined the progress of the nation's 100 largest cities and their surrounding suburban areas toward achieving Healthy People 2000/2010 goals for two measures of infant health: low birth weight (LBW) and infant mortality (IM). Using data from the National Center for Health Statistics, we compared 1990 and 2000 urban and suburban LBW and IM rates to target rates for Healthy People 2000 and 2010 objectives. Although the 2000 LBW weight rate for the 100 largest cities was higher than the average for the suburbs (8.9% vs. 7.1%), the increase in LBW rates for the suburbs was nearly four times that of the cities (15.7% vs. 4.1%). Suburban and urban white infants led the increases in LBW rates; urban and suburban black infants showed a slight decrease or no change in LBW rates. Neither cities nor suburbs, on average, met the 2000 target rate of 5%. It appears unlikely that most of the 100 largest cities and suburbs will meet the Healthy People 2010 goal, which remains at 5%, without reductions in preterm births, nationally on the rise. The IM rate declined across most cities and suburbs between 1990 and 2000. However, the 100 largest cities on average did not meet the 2000 IM rate target of 7 infant deaths per 1000 live births; their suburbs did (8.5 vs. 6.4, respectively). The cities and suburbs that did not meet the 2000 target may be especially challenged to meet the 2010 goal for IM unless rates of preterm births are reduced. With the continuing black-white disparities in LBW and IM rates and the overall differences in the racial composition of the largest cities and suburbs, strategies for meeting Healthy People goals will likely need to be targeted to the specific populations they serve.
