Primary health workers( behvarzes) have the responsibility of birth control education in rural areas. To evaluate the practice of behvarzes in their own birth spacing, a questionnaire was prepared by the investigators and it was completed by married behvarzes. The results were as follows: of 437 behvarzes 50.8℅ were females and 84(19.2℅) were couples. Mean age of behvarzes was 29.4 and the mean duration of their employment was 7 years. The mean age of marriage was 20.2℅ among females and 18.6℅ years among the wives of the male behvarzes. The mean age of first pregnancy was 21.4 and 19.3 years respectively, but the mean number of their children was 2 . The mean of birth spacing among behvarzes was 32 months. The mean interval between the last two pregnancies was 36.6 months in female behvarzes, 34.8 among the wives of males, and 26.9 in the rural women. The mediam of birth spacing of last two deliveries were 35.9, 32.8 and 21.7 respectively. Overall , parameters related to behvarzes, practice in fertility related behaviours, compared with rural women, though not completely acceptable , seem by and large satisfactory.
