We conducted a meta-anlysis of 18 studies published between 1996 and 2008 that investigated the association between birth weight and breast cancer. Women whose own birth weight was greater than 4000 grams or 8.5 pounds had a 20% higher risk of developing breast cancer.

Morse, S. B., Zheng, H., Tang, Y., Roth, J. (2009).Early school age outcomes of late preterm infants. Pediatrics, 123(4),e622-e629.

Late preterm infants represent a significant portion of preterm deliveries. Until recently, these infants have received little attention because of assumptions that they carry minimal risk for long-term morbidities. The purpose of this study was to compare prekindergarten and kindergarten outcomes among healthy late preterm infants, 34 to 36 weeks’ gestation at birth, and healthy term infants, 37 to 41 weeks’ gestation at birth.

Figlio, D., Hamersma, S., and Roth, J. (2009) Does prenatal WIC participation improve birth outcomes? New evidence from Florida. Journal of Public Economics, 93, 235-245.

By focusing on small for gestational age infants, we consider one of the possible pathways through which prenatal nutrition affects fetal growth.

Rao, P.V., Li, Haihong, L., and Roth, J.(2008) Recursive Path Models when Both Predictor and Response Variables are Categorical. Journal of Statistical Theory and Practice, 2, 663-676.

In this paper, we develop an approach for recursive path analysis when both predictor and response variables are categorical. The approach defines direct and indirect effects in terms of relative risks and odds ratios and can be used with common categorical data models such as Poisson, probit and logistic regression models. The method can be implemented using standard statistical software such as the GENMOD procedure of SAS.

Liu, X. and Roth, J. (2008). Development and validation of an infant morbidity index using latent variable models. Statistics in Medicine, 27, 971-989.

In this paper, we develop extended latent variable (LV) models and modified Gauss-Newton algorithms for multiple multinomial morbidity outcomes with complete responses. By assuming the marginal distribution of the LV to be log-normal, we model the conditional probability of each outcome as a nonlinear function of the LV, which has properties similar to the logistic function. The estimated generalized nonlinear least-square method is used to solve equations for parameters of interest.

We justify and recommend using standardized risks, i.e., standardized probabilities, which do provide information about prevalence, in addition to adjusted odds ratios, for pairwise comparisons of the levels of a significant factor. We illustrate the advantages of generally reporting standardized risk estimates in the context of assessing the effect of blood lead levels during the preschool years on occurrence of academic problems in kindergarten.

Encyclopedia on Early Childhood Development. Montreal: Centre for Excellence for Early Childhood Development.

This commentary assesses claims made on behalf of two of the most thoroughly researched family-centered interventions for preterm infants: the Newborn Individualized Developmental Care and Assessment Program (NIDCAP), which starts at birth and ends at hospital discharge, and the Infant Health and Development Program (IHDP), which begins at hospital discharge and ends at the child’s third birthday.

We investigate the practical impact of differences between three models for calculating value added measures of school performance (by grade and subject area): hierarchical linear models, layed mixed effects models, and simple fixed effects models. The question of whether to adjust for student level variables such as minority status and poverty remains the most important issue facing implementation of a school accountability system.

Guoerguiva, R. V., Carter, R., Shah, N., L, Mahan, C. S., Ariet, M., Roth, J., Thompson, D., Teng, C. H., Bucciarelli, R., Curran, J., & Resnick, M. B. (2003). A risk assessment screening for very low birthweight. Maternal and Child Health Journal, 7(2), 127-136.

Generalized Linear Modeling was used to estimate associations between risk factors and very low birth weight. A risk assessment system was then developed using the estimated model. The resulting screening test was compared with the one used by the Florida State Department of Health in terms of sensitivity and specificity on an independent validation sample. The proposed screening tool had comparable specificity to the Healthy Start screening tool but significantly better sensitivity.

This study found that race, sex, and transport status correlated significantly with survival. Using multivariable statistical procedures to generarte predicted survival probabilities for different subpopulations can help physicians develop clinical guidelines for extending care to infants at the threshold of viability.

This study followed neonatal intensive care unit graduates ( n = 457) into Floria public schools and compared thier educational outcomes with those of newborn nursery graduates (n = 656).  The only clear-cut neonatal intensive care unit effect occurred among children born with sensory or physical imparments.
