The Integrated Project (IP), originated by the Japanese Organization for International Cooperation in Family Planning (JOICFP) was started in China in 1984. The 2nd phase covered 210,000 people in 8 townships in Inner Mongolia Autonomous Region, and others in Liaoning, Jiangsu and Shandong Provinces, in 1987-1989. 2 pilot areas, monitored by representatives from IPPF's East and Southeast Asia and Oceania Region in September 1990, showed significant gains in contraceptive prevalence as well as health benefits and community acceptance. The IP consists of integrated family planning, maternal and child health and parasite control for rural areas. In Tumotezuo County, Inner Mongolia, the village of Bashi with 2526 people was mobilized to construct its own health clinic with a delivery room and a maternal and child health unit, where night classes were held for women. Because of antihelminthic treatment, installation of water pipes and toilets, parasites were controlled. Neighboring towns benefited by treatment of common disorders such as anemia and rickets. In the pilot areas there have been no maternal deaths in 3 years, and declines in perinatal mortality from 33.3 to 17.9/1000, and in infant mortality from 35.1 to 21.5/1000. Incidence of roundworm infection fell from 27.8 to 7.6%, Contraceptive prevalence, already high at 91.8%, rose to 93.7% among the Han majority, and from 65.9 to 77.2% in minorities. Family planning was spread by using the "core household" approach. The large household of the village leader, with 13 women of childbearing age, subscribed to several periodicals on family planning and farm and home economics, so people learned how to become well off by raising vegetables and pigs, and how to limit family size with the correct concept of a happy healthy family.
