Developmental Well-Being among Low and Normal Birth Weight U.S. Puerto Rican Children

Abstract

Low birth weight is a more common occurrence among Puerto Rican children than among children from most other racial and ethnic groups in the United States, and they are more likely to experience the added risk of living in poverty. This study addresses what is protective for the development 602 normal birth weight and 554 low birth weight children from the Puerto Rican Maternal and Infant Health Study. The results presented in the current analysis identify several protective influences for development (particularly maternal social support, medical insurance, and paternal employment) among low birth weight children (who are at a high risk for developmental problems), and almost none for normal birth weight children. The results largely support the contention that protective factors emerge, or increase in strength, only in the presence of risk, indicating the use of targeted child health programs based on birth weight are an effective and efficient way to improve the developmental well-being of young Puerto Rican children in the United States.
