Postpartum fertility behaviours and contraceptive use among women in rural Ghana

BACKGROUND: Although most women would want to wait for more than two years before having another baby, their fertility behaviours during the first year following birth may decrease or increase the length of the birth interval. The objectives of this study were to: assess how protected postpartum women in the Mfantseman municipal were against pregnancy, based on their patterns of amenorrhoea and sexual abstinence; determine the timing of postpartum contraception in relation to amenorrhoea and sexual abstinence; and determine the predictors of postpartum contraceptive use. METHODS: This was a prospective study carried out in the Mfantseman Municipality of the Central region of Ghana. Out of 1914 women attending antenatal clinic in the municipal within the study period, 1350 agreed to be part of the study to ascertain their postpartum fertility and contraceptive behaviours a year following delivery. These women were traced to their communities using telephone and house numbers provided and only 1003 of the women were finally traced and interviewed. The women were asked about their breastfeeding behaviour, postpartum sexual abstinence, duration of amenorrhoea and postpartum contraceptive use. RESULTS: The mean age of the respondents was 29.9 ± 6.5 years; adolescents constituted the least proportion (3.3%) of the women. More than half (54.1%) of the women had Middle, Junior secondary school or Junior high school education. Most (43.3%) of the women were married by means of traditional rites and more than half (51.4%) of them were petty traders. The mean durations of breastfeeding, amenorrhoea and sexual abstinence were 6.6 ± 2.8 months, 7.8 ± 3.8 months and 4.4 ± 3.1 months respectively, whilst mean time of first contraceptive uptake was 3.5 ± 2.7 months postpartum. The time to first use of modern contraceptive method during the postpartum period indicates that about 50% of the women had started use of modern contraceptive methods by 2.7 months postpartum, and occured 0.6 and 3.6 months before sexual relations and resumption of menses respectively. Occupation (likelihood ratio p = 0.013), area of residence (likelihood ratio p = 0.004), mode of delivery (likelihood ratio p < 0.001), breastfeeding (p = 0.024), period since delivery (p < 0.001), preferred number of children (p < 0.001) and parity (p < 0.001) were found to be predictors of postpartum contraceptive use. CONCLUSION: Postpartum women in the Mfantseman municipal who did not use contraceptives or delayed in the use of contraceptives after birth were least likely to be protected against pregnancy in the post partum period, whilst those who adopted postpartum family planning were likely to be better protected because they were likely to adopt it within the first three months after birth and before the onset of sexual relations and first menses. The predictors of postpartum contraceptive use were breastfeeding pattern, occupation, parity, preferred number of children, period since delivery, place of residence and mode of delivery.
