Prelabour caesarean section and neurodevelopmental outcome at 4 and 12 months of age: an observational study.

ABSTRACT:

Background

With prelabour caesarean section rates growing globally, there is direct and indirect evidence of negative cognitive outcomes in childhood. The objective of this study was to assess the short-term neurodevelopmental outcomes after prelabour caesarean section as compared to vaginally born infants.

Methods

We conducted a prospective, observational study of infants delivered by prelabour caesarean section at the Hospital of Halland, Halmstad, Sweden and compared their development with an historical group of infants born by non-instrumental vaginal delivery.

Results

Infants born by prelabour caesarean section were compared with a group of vaginally born infants. Follow-up assessments were performed at 4 and 12 months. Prelabour caesarean infants (n = 66) had significantly lower Ages and Stages Questionnaire, second edition (ASQ-II) scores in all domains (communication, gross motor, fine motor, problem solving and personal-social) at 4 months of age with an adjusted mean difference (95% CI) of - 20.7 (- 28.7 to - 12.6) in ASQ-II total score as compared to vaginally born infants (n = 352). These differences remained for gross-motor skills at the 12 month assessment, adjusted mean difference (95% CI) -4.7 (- 8.8 to - 0.7), n = 62 and 336.

Conclusions

Adverse neurodevelopmental outcomes in infants born by prelabour caesarean section may be apparent already a few months after birth. Additional studies are warranted to explore this relationship further.

Project description:ObjectivesCaesarean section (CS) conducted before labour (prelabour CS (PLCS)), compared with vaginal birth, may pose additional maternal and perinatal risks. No multicountry analysis has examined PLCS in low-income and middle-income countries (LMICs). This study assessed rates, risk factors and associations of PLCS with perinatal outcomes in LMICs.DesignPopulation-based cross-sectional surveys.SettingDemographic and Health Surveys conducted between 2015 and 2018 in 26 LMICs (13 countries in Africa, 11 in Asia and 2 in the Americas).ParticipantsWomen aged 15-49 years with singleton term births.Outcome measuresMain outcomes were early neonatal mortality, neonatal mortality, early breastfeeding (within 1 hour of birth), skin-to-skin contact and duration of hospital stay.Results255 227 women were included in the main analysis. Average rates of primary PLCS ranged from 1.3% in Zambia to 19.5% in Maldives. Median PLCS rate was 1.8% in the poorest versus 5.8% in the richest subgroups.Higher maternal age, education, economic status and BMI, lower parity, urban residence, delivery in private hospitals, larger baby size, having health insurance, more antenatal care (ANC) visits, ANC by a doctor and ANC in private hospitals were associated with increased primary PLCS.Across the 26 countries, primary PLCS, compared with vaginal delivery, was associated with increased neonatal mortality (adjusted odds ratio, aOR 1.2, 95% CI 1.0 to 1.5), decreased early breastfeeding (aOR 0.4, 95% CI 0.3 to 0.5) and skin-to-skin contact (aOR 0.4, 95% CI 0.3 to 0.5) and longer hospital stay (aOR 6.6, 95% CI 5.9 to 7.4). No significant association was found for early neonatal mortality (aOR 1.2, 95% CI 0.9 to 1.5).ConclusionPrimary PLCS, compared with vaginal birth, is associated with adverse perinatal outcomes in singleton term pregnancies in LMICs. Caesarean births should be audited regularly to monitor trends, appropriateness and context-specific drivers of CS.

Project description:ObjectiveTo provide an update on economic related inequalities in caesarean section rates within countries.DesignSecondary analysis of demographic and health surveys and multiple indicator cluster surveys.Setting72 low and middle income countries with a survey conducted between 2010 and 2014 for analysis of the latest situation of inequality, and 28 countries with a survey also conducted between 2000 and 2004 for analysis of the change in inequality over time.ParticipantsWomen aged 15-49 years with a live birth during the two or three years preceding the survey.Main outcome measuresData on caesarean section were disaggregated by asset based household wealth status and presented separately for five subgroups, ranging from the poorest to the richest fifth. Absolute and relative inequalities were measured using difference and ratio measures. The pace of change in the poorest and richest fifths was compared using a measure of excess change.ResultsNational caesarean section rates ranged from 0.6% in South Sudan to 58.9% in the Dominican Republic. Within countries, caesarean section rates were lowest in the poorest fifth (median 3.7%) and highest in the richest fifth (median 18.4%). 18 out of 72 study countries reported a difference of 20 percentage points or higher between the richest and poorest fifth. The highest caesarean section rates and greatest levels of absolute inequality were observed in countries from the region of the Americas, whereas countries from the African region had low levels of caesarean use and comparatively lower levels of absolute inequality, although relative inequality was quite high in some countries. 26 out of 28 countries reported increases in caesarean section rates over time. Rates tended to increase faster in the richest fifth (median 0.9 percentage points per year) compared with the poorest fifth (median 0.2 percentage points per year), indicating an increase in inequality over time in most of these countries.ConclusionsSubstantial within country economic inequalities in caesarean deliveries remain. These inequalities might be due to a combination of inadequate access to emergency obstetric care among the poorest subgroups and high levels of caesarean use without medical indication in the richest subgroups, especially in middle income countries. Country specific strategies should address these inequalities to improve maternal and newborn health.
