"Reproductive Patterns and Child Mortality in Guatemala" [PDF]
Studies in Family Planning, 1987 Abstract In this paper, we investigate the association of child mortality with maternal age, parity, birth spacing, and socioeconomic status, in a sample of Guatemalan children who were included in a public health intervention program. Our results indicate that maternal age, birth order, and the length of the previous and following birth
