[BDSP. Notice produite par INIST Oo0avR0x. Diffusion soumise à autorisation]. This study presents a structural equation model describing the influence of stressful life experiences on low birth weight. Data were gathered prospectively in two waves from 5295 inner-city women as part of a a city-wide preterm birth prevention project. Using interviews and the medical record. over 200 measures were gathered on each mother and her infant, where each measure was included because of its relevance documented in the risk factor literature. Seventeen of these measures reflected real life stressful experiences and through measurement modeling, eleven of these measures were chosen to represent three underlying measures of stress : economic stress, family stress, and the lack of social support. This study incorporates these psychosocial stressors into a full structural equation model to show their influence on addictive behavior and low birth weight The full model emerged from tests of alternative causal conceptualizations of how these stressors influence each other and low birth weight - whether their influence on low birth weight in simple and direct, or whether their influence is mediated by addictive behaviors.
