Association of socioeconomic status with adverse birth outcomes at the Women and Newborn Hospital of the University Teaching Hospitals in Lusaka, Zambia

Background: Low socioeconomic status has generally been associated with adverse birth outcomes worldwide. Adverse birth outcomes significantly contribute to perinatal morbidity and mortality worldwide with some literatures showing conflicting results. At Women and New-born Hospital in Zambia, this relationship had remained unclear among women who experienced poor neonatal outcome; hence the study was done to explore this association between socioeconomic status and adverse birth outcomes. Methods: A retrospective cohort study was conducted. Secondary data from ZAPPS study that had been collected prospectively between August 2015 and September 201 7 was retrieved. Altogether, 1,450 participants' information was retrieved, out of which 1,084 data records were set out for analysis after excluding those not meeting eligibility criteria. Socioeconomic status was an explanatory variable which was estimated using the standardized wealth score derived from principal component analysis of 14 variables. The wealth quintiles were further categorised into poor and not poor. Response variables were low birth weight, preterm birth and small for gestation age. SPSS version 21 was used for data analysis and p value< 0.05 was significant Results: This study found the incidences of SGA, LBW and preterm births to be 164, 124 and 13 5 per 1000 live births respectively. In survival analysis, the proportion of babies who survived LBW among mothers who were poor was lower (82.9%) compared to babies born to rich mothers (87.5%) (p-value = 0.189). Furthermore, the proportion of babies who survived SGA for the poor was lower (79 .1 % ) compared to babies born to none poor mothers (85.8%) (p-value = 0.032) and preterm birth for the poor (78.4%) compared to babies born to mothers who were rich (83 .6%) (p-value = 0.022). In multiple Cox regression analysis socioeconomic status was not a significant risk factor for SGA ( aHR = 1.08; 95% CI; p=0.099), LBW and preterm birth (aHR = 1.17; 95% CI; p= l.41). However, male babies (aHR = 1.80; 95% CI; p=0.012), domestic violence or abuse during pregnancy (aHR = 3.48; 95% CI [1.59 - 7.34]; p = 0.002) and maternal anaemia (aHR = 2.1; 95% CI; p = 0.019) were risk factors for SGA while prior preterm birth ( aHR = 2.02; 95% CI; p = 0.002), HIV infection (aHR = 1.22; 95% CI; p = 0.040) and anaemia (aHR = 1.37; 95% CI; p = 0.009) were predictors of preterm delivery. Conclusion: There was no statistically significant association between low socioeconomic status and adverse birth outcomes although being pregnant with a male baby, HIV infection, anaemia and prior preterm birth were significantly associated with SGAand preterm

Maternal factors and short-term outcome associated with episiotomy during vaginal delivery at the Women and Newborn Hospital, Lusaka, Zambia

Objective:To explore the maternal factors and short-term outcomes associated with episiotomy during vaginal delivery at Women and Newborn Hospital, Lusaka, Zambia.Materials and Methods:An unmatched case control study was conducted in postnatal wards of Women and New-born hospital in Lusaka, Zambia between November 2019 and April 2020 with convenient sample for the cases and systematic sample for the controls.Asemi-structuredintervieweradministered questionnaire was used and 102 participants (cases) who had episiotomy performed were recruited while 204(controls) werewithoutepisiotomy.Results:Atotal of 306 (102 are cases and 204 are control) were included. Age was found to be a good predictor of episiotomy in that those younger than 18 years were more than seven times likely to have an episiotomy (AOR=7.65; 95%CI 1.36-18.21; p=0.035). It was also found out that primi gravidas were five times likely to have an episiotomy performed compared to parous women (OR=4.96; 95%CI 2.58-9.52; p<0.001). Out of those delivered by a midwife, 73(28.3%) participants had an episiotomy performed compared to 29(60.4%) deliveredbyamedicalofficer.Multivariateregression it was shown that being delivered by a midwife was protective against an episiotomy (OR=0.260; 95%CI 0.14-0.49; p=0.001). Out of the 102 participants who had an episiotomy, only two had third degree tear extension. It was also noted that 99 out of 102 (97%) participants who had an episiotomy experienced post-delivery perineal pain compared to 94 out of 204(46%) of those who had no episiotomies. In univariate analysis, it was found that post-delivery perineal pain was associated with episiotomy (p<0.001). It was further found that those who had an episiotomy performed were about 4 times likely to experience perineal pain post- delivery (OR=3.8; 95%CI 1.2-12.3) Conclusion:Maternal factors associated with episiotomy includedage,parity,method of induction,and the personnel conducting the elivery. Shorttermmaternaloutcomesofepisiotomy were perineal tear extension, and post-delivery perineal pain. It was found that 8.5% of women had undergone an episiotomy done on them. Health professional conducting deliveries should be educated on indications of episiotomy, patient selection during episiotomy and trained on surgical skills to repair episiotomy to reduce morbidity associated the procedure.
