| Abstract: | In the Philippines more and more couples are practicing natural family planning (NFP), but there is a need to improve instruction on this method to increase its effectiveness. Calendar rhythm has been the most popular technique of NFP, but failure rates have been high. This could be changed by improved calendar rythm instruction and the introduction of newer, more effective natural techniques like the basal body temperature, cervical mucus, and symptothermal methods. Dr. John E. Laing, in a paper entitled "research on Natural Family Planning in the Philippines," examines the trends in NFP and summarizes major findings of past research related to NFP and the status of current research. It also discusses the implications of such findings for the National Population Program and the needs for current research. Cting World Fertility Survey (WFS) data on 19 developing countries, Laing states that the Philippines is second only to Peru in current and past use of the rhythm method. He also indicates that since the start of the National Population Program in 1971, rhythm has been offered as an official program method. Yet, in the early years of the program rhythm was not promoted as actively as the other family planning methods. In the last few years, program, officials have become more interested in NFP. 1976 National Acceptor Survey (NAS) data showed that rhythm reduced fertility by 78% compared to the condom's 79%, oral contraceptive's 94%, and the IUD's 98%. A comparison of data from the 1972, 1974, and 1976 NAS indicated a decline in continuation rates and an increase in overall pregnancy rates for all methods except rhythm. The overall pregnancy rate of rhythm declined, but there was no significant change in continuation rate. Laing suggests that probably, while the national population program was increasingly recruiting less motivated couples to try other methods, the rhythm acceptors, who were largely self initiated, mantained earlier levels of motivaton. Evidence points to the widespread use of crude formulas that do not take into account individual variations in cycle length. Many users do not even fully understand the mechanism by which rhythm affects fertility. There is also little knowledge among acceptors of the new and more reliable techniques of NFP for identifying the safe and unsafe periods. Despite problems, a considerable number of acceptors still prefer rhythm to other methods. The commission on population has embarked on a solution to some of the problems by committing itself to the training of volunteers of community-based organizations, particlarly lay leaders. 3 large scale projects are planned for this purpose. |
