PIP: This paper, which reports on the effect of health services in Kanniambadi block, is a continuation of a previous paper on knowledge, attitude and practice surveys in 3 blocks in North Arcot District, Tamil Nadu. It was found that knowledge of family planning is poor, especially for temporary methods, even in the service area. However, both attitudes and practice showed a definite improvement in the service area. Knowledge of antenatal care was also poor, with only slight improvement in the service area. The influence of different factors on family planning and implications for health education are discussed. More use of group methods, and more education about temporary methods is recommended, as well as close linkage between health and development programs.
