Factors that relate to reproductive patterns in 129 families after the birth of a child with phenylketonuria (PKU) include birth order of the index child, age of the parents at the birth of the index child, and expressed intentions of the parents whether or not to have additional children. Factors that do not correlate with reproductive histories include knowledge of the genetic and metabolic nature of PKU, the relationship of PKU to mental retardation and special diet, parental upset about the diagnosis, sex of the affected child, parental IQ, religion, education, and social class. Correlations found related to the question, "Is PKU the reason you don't want more children?" include stress factors in family functioning, mother's upset with the diagnosis, father's concerns about being a carrier, sex of the child with PKU, and degree of knowledge about PKU. Many of the Collaborative Study clinics tend to be more concerned about the consequences of PKU on the family than on society, and feel that families should receive genetic counseling to determine their reproductive risks and future plans. Upon self-report, many clinics declare their counseling to be either "completely nondirective" or making a "conscious effort to be nondirective."
In response to 1982 legislation and 1984 changes in the Wisconsin Adoption Records Laws requiring the collection of a medical-genetic history at the time of termination of parental rights, a continuing education program in genetics was conducted for adoption workers in 1984 and 1985. The education program provided 14 workshops in five locations throughout the state and consisted of a variety of formats and levels of training. In all, 164 participants were trained at least at the introductory level with approximately 40 of these individuals taking part in the advanced levels of training. Evaluations of the training by participants and by a sample of the agency supervisors of trainees ranked the program very highly. A review of genetic history forms completed in post-training sessions verified the expectation that training was beneficial. Trained workers completing the medical-genetic history forms scored somewhat higher than untrained workers and much higher than parents who completed the forms without professional guidance. Medical-genetic history forms completed by birth fathers as part of step-parent adoptions contained little to no useful information about the birth father's genetic background.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
