Unintended pregnancy and the associated factors among pregnant females: Sukh Survey-Karachi, Pakistan.

OBJECTIVE: Unintended pregnancy has become a substantially growing reproductive health concern in South Asian region. The objective of this survey was to assess the magnitude of unintended pregnancy along with its correlates among currently pregnant women residing in Karachi. METHODS: A community based, multistage, cross-sectional study was carried out among 612 currently pregnant women from squatter settlements of Karachi, inquiring for "unintended pregnancy", outcome of interest. Multivariable logistic analysis was done using SPSS v.19 to determine associated factors. RESULTS: Of 612 pregnant women interviewed, 168(27.4%) reported their pregnancies as unintended. The multivariable regression identified a high likelihood of unintended pregnancy among females aged ≥ 35 years (adjusted odds ratio =3.0, 95% Confidence Interval =1.2 to 4.9)], having: ideal family structure perceived as ≤ two children (Adj. OR=2.3, CI=1.3 - 4.5), no media exposure (Adj. OR=2.9, CI=1.7 to 5.0), no inter-spousal communication about planning a family (Adj. OR=1.5, CI=1.1 - 2.3), ≥5 children (Adj. OR=7.2, CI: 3.4 to 15.1), more sons than daughters (Adj. OR=4.0, CI=1.7 to 6.7), and positive attitude towards using family planning method (Adj. OR=1.8, CI=1.2 to 2.8). Unintended pregnancy decreased with increased age at marriage (Adj. OR= 0.8, CI=0.8, 0.7 - 0.9) and with use of contraceptive methods ever in life (Adj. OR=0.7, CI=0.5 - 0.9). CONCLUSIONS: We found important predictors which suggest policy measures for enhancing media exposure, promoting effective family planning usage, and incorporating behaviour change models in reproductive health clinics to modify fertility intentions of couples.
