title: Exploring the persistent black risk of low birthweight: findings from the GLOWBS Study.
abstract: Results are presented from the Galveston Low Birthweight Survey (GLOWBS) Study, a tri-ethnic survey (N = 1,179) of live, single births, conducted in Galveston, Texas, from 1986 to 1987. Four principal findings emerged pointing to a persistent black risk for low birthweight (less than 2,500g). First, black infants (2,997g) have significantly lower mean birthweight than either Anglos (3,281g) or Hispanics (3,270g). Second, blacks are at significantly higher risk of low birthweight than nonblacks (risk ratio = 1.71). Third, despite controlling for a variety of pregnancy- and health-related, psychosocial, socioeconomic, and health services factors (including even gestational length), being black still exerts a significant, inverse effect on birthweight (beta = -0.137). Fourth, of the above factors only gestational length (R2 = 0.39) accounts for more than a negligible amount of the total variance in birthweight among blacks. These findings are discussed, and several lines of follow-up research are proposed.
