Child disability and mothers' tubal sterilization

CONTEXT: The needs of children with disability can be substantial, leading some parents to consider contraceptive sterilization to prevent additional births.
METHODS: Matched records from the 1993 National Health Interview Survey and the 1995 National Survey of Family Growth were used to investigate the relationship between child disability and mothers' sterilization. Data included the birth records of 8,711 children, information on older children in the household, and the mothers' background and reproductive characteristics. Logistic and Cox regression models were used to estimate the effect of the birth of a child with a disability on the risk of mothers' sterilization.
RESULTS: The birth of a child with disability has no effect on the likelihood that a mother will undergo sterilization within the next month; however, women who have an older child with severe disability are more likely than those whose older children are nondisabled to undergo sterilization within a month after the birth of another child (odds ratio, 2.6). Severe disability in a newborn significantly increases the risk of sterilization 1-36 months after birth (risk ratio, 1.7); severe disability among older children also appears to increase the risk of sterilization 1-36 months after birth (1.5), although this result was only marginally significant.
CONCLUSIONS: Women often respond to the birth of children with disabilities by changing their fertility plans, although usually not immediately unless they have older children with severe disability. These findings are consistent with parents' desire to have a nondisabled child and with their need to care for an exceptional child by forgoing additional births.
