The alterations of cervical cytology in 3206 'users' of steroid contraceptives (SC) and 2394 'non-users' (controls) have been followed by means of five surveys for eight years. The alterations of cervical cytology have not differed significantly between the two groups seven years after the first examination, but have differed significantly between younger and older women in both groups. The incidence of progression to and regression from PAP III class cytology was more frequent than the prevalence, but again it did not differ significantly between users of SC and controls. In pairs of SC users and controls, matched by year of birth and presence of PAP III cytology, the users differed significantly from controls in the frequency of pregnancy, abortion and the circumcision of their husbands. The highly prevalent risk factor common to both groups was vaginal infection, including Trichomonas vaginalis. In conclusion the author offers some comments and raises questions and speculations based on the findings of this study about the nature of alterations of cervical cytology.

31,233 women in the regions of Bosnia and Hercegovina were questioned in 1973 in order to determine the success of communication about family planning and the variables involved in the different reactions of the subjects. The most effective method (44.9%) of communication was that of direct, ''face-to-face'' contact, followed by dispensing of information by the Commision for Abortion (24.2%), advertising (7.3%), and by means of maternity service (2%). The 25-39 year old age group of women displayed the most interest in contraceptive services. The potential of contraceptive education in schools is emphasized, although at this point is inadequately taken advantage of.

The results and statistical tables are presented from a KAP study carried out in 1970 on public knowledge, attitudes, and practice in family planning in Yugoslavia. The study's objective was to determine the mechanism of population growth in the various individual provinces, as the growth rates of these individual areas vary widely, causing a very unstable level of overall growth for the country. 7982 women from all parts of the country, aged 15-44 years, were questioned as to their family planning programs. An analysis was also made of factors influencing the growth rates and, indirectly the family planning programs, such as socioeconomic levels of various groups of the population, effectiveness of use of contraceptives, and the solidarity of marriages. Full report on this study was presented in 2 volumes in 1972.
