PIP: South Carolina ranks 18th among all US states with regard to its incidence of adolescent pregnancies. No formal sex education was provided in any of Spartanburg County's schools before 1976, even though adolescents aged 12-16 years accounted for 9% of all deliveries at Spartanburg Regional Medical Center (SRMC), a county-owned tertiary care center which accepts complicated obstetrical cases from a three-county catchment area. Docs Oughta Care (DOC), an international voluntary organization of concerned primary care physicians, together with teams of male and female family medicine residents at SRMC, developed slide presentations on human reproductive anatomy, venereal disease, and pregnancy prevention. The presentations were factual, with neither scare tactics nor heavy moral overtones. Respect for self and others, independent thinking, a positive self image, and understanding peer pressures were central themes. Following the announcement of the availability of the teams to all Spartanburg County schools in the fall of 1978, junior and senior high schools in the four largest of seven school districts requested visits. The majority of students reached were aged 13-17 years. However, lack of resident interest and leaders led to waning enthusiasm for the presentations after 1980 and their cessation during 1982-85. Within 2-3 years of the program's launch, the percentage of adolescents under age 16 years delivering babies at SRMC declined from the usual level of 9% to slightly more than 4% of all deliveries. This reduction persisted beyond the decline of the DOC program, although some recidivism was noted as the peak of the effort passed.
