OBJECTIVE
To estimate the effect of contraception on fertility in the border region of Chiapas, Mexico.
MATERIALS AND METHODS
In 1994 an epidemiological cross-sectional study was carried out on a representative sample of 1,560 non-indigenous women between ages 15 and 49 in the border region of Chiapas. The prevalence of contraception practices and the total fertility rates (TFR) were obtained and stratified by rural, intermediate and urban communities. TFR were compared between women who had never used contraceptives and those who had used them.
RESULTS
The estimated TFR was 3.67 and varied from 4.14 in rural areas to 3.36 in urban areas. There were no differences in the TFR (3.74 and 3.88) nor in the average live births (3.47 and 3.48) between women who had never used contraceptives and those who had used them.
CONCLUSIONS
The major effect of contraception on fertility was observed in rural areas. Factors which influence the small impact of contraception on fertility include the late use of these methods and the early age of first union among users.
