PIP: 1390 women aged 15-44 were surveyed between February-June 1988 in the vicinity of the Park Health Education Center by the Ankara University School of Medicine, Department of Public Health. Within this sample, the survey focused on the knowledge, attitude and behavior of the 1082 married women, regarding birth control. Birth control pills, IUDs, and condoms were classified as effective modern birth control methods. Other less effective traditional methods were classified as ineffective. Analysis of the data indicated 74.2% of the subjects resort to some form of birth control while 66.2% use an effective modern method. Age, education, work status, number of children and type and location of housing influence family planning decisions. In general, the women using birth control are primary school graduates aged between 25-39, living in urban areas for at least 5 years. Most have 2 to 3 children and have had an abortion. The most frequently used method of birth control is the IUD. It is notable that 29.5% use the ineffective withdrawal method. 58.62% of the women who do not use birth control, avoid family planning because of their husbands. These women have 2 or more children and are illiterate or primary school graduates between the ages of 25-35 when they are most likely to become pregnant. Family planning services should be geared towards educating these families, especially the husbands. Education services should also target families using the withdrawal method and the 35-44 age group of women who show a low percentage of contraceptive use.
