Analysis on reasons of unwanted pregnancy by women of child-bearing age and its strategies

Wang Daiquan,Liu Changyan,Xiang Qiong and Ma Daici

Strategic Study of CAE 2014, Volume 16, Issue 5,   Pages 11-15

Abstract:

This paper makes relative questionnaire from cluster sampling of induced abortion from Jan. 2011 to May 2013 as well as looking up medical records to analyze reasons of unwanted pregnancy. Among 1 360 cases of unwanted pregnancy，21.62 % are unmarried，78.38 % are married；age distribution ranges between 20～39（73.82 %）；pregnant time distri-bution is between the second and third pregnancy（57.87 %）；44.34 % is due to contraceptive failure，55.66 % is due to no contraceptive use；IUD accounts for 10.51 % of choice of contraceptive measures，use of condoms is 10.51 %，contraceptive is 8.24 %，external use is 6.62 %， other mean is 8.46 %. The main reasons of unwanted pregnancy are due to taking chances with no contraceptive use or no contraceptive use after removal of IUD；98.90 % of interviewed subjects know contraceptive knowledge，15.37 % know emergency contraception，18.38 % know the necessity of contraception measures for nursing mothers. Married people get information of the contraception knowledge mainly from medical workers，family planning cadres，publicity materials. More farmers and migrant workers are willing to get free services than urban residents，government employees，commercial service personnel and other migrants.
