Trend and decomposition analysis of risk factors of childbirths with no one present in Nigeria, 1990-2018

Correlates of non-institutional delivery to delayed initiation of breastfeeding in Nigeria: logit-decomposition and subnational analysis of population-based survey

BACKGROUND

Studies have connected newborn delivery settings and modality to optimal breastfeeding, but how it influences untimely initiation, mostly prevalent in sub-Saharan Africa is unknown. Hence, the role of home delivery on delay initiation of breastfeeding (DIBF) in Nigeria was investigated to inform evidence-based strategy for improved breastfeeding practice.

METHODOLOGY

This is a secondary analysis of births (11,469 home and 7632 facility delivery) by 19,101 reproductive age women in the 2018 NDHS. DIBF is the outcome, home birth is the exposure, and explanatory variables were classified as: socio-demographics, obstetrics and economic factors. Descriptive statistics (frequencies and percentages) were reported, and bivariate (chi-square) analysis was carried out at 20% (p < 0.20) cutoff point. Multivariable logistic regression assessed the probability and significance of the outcome per place of birth. Multivariate decomposition further evaluated the endowment and coefficient effect contribution by independent factors to the outcome. Analysis was carried out at p < 0.05 (95% confidence level) on Stata.

RESULTS

56.6% of mothers DIBF, with 37.1% and 19.5% from home and facility delivery, respectively. Home delivery (AOR = 1.34, 95% CI 1.17-1.52) increase the chance of DIBF by 34%, while DIBF probability reduces by 26% in facility delivery (AOR = 0.74, 95% CI 0.65-0.85). DIBF is 5 times more likely in caesarian section delivery (AOR = 5.10, 95% CI 4.08-6.38) compared to virginal birth in facility delivery. Skilled antenatal provider, parity and wealth are negatively associated with DIBF in home birth, while undesired pregnancy, rural residency, partial/no skin-to-skin contact and large child size positively influence DIBF in both home and facility delivery. Skilled antenatal provider (C =  - 66.3%, p < 0.01) and skin-to-skin contact (C =  - 60.6%, p < 0.001) contributed most to reducing the negative DIBF effect with 69% and 31% overall characteristics and coefficient effect component, respectively. DIBF is more likely in Bauchi and Sokoto but less likely in Bayelsa.

CONCLUSIONS

High DIBF prevalent in Nigeria was largely due to elevated rate of home birth, positively associated with DIBF. Caesarian section delivery though heightens the chance of DIBF in facility delivery. Strengthening utilization of skilled provider and skin-to-skin contact can eliminate two-third of the adverse DIBF effect and improve early initiation rate. Adopting this strategy will bridge home-facility delivery gap to achieve optimal breastfeeding practice.

Effect of caesarian section delivery on breastfeeding initiation in Nigeria: logit-based decomposition and subnational analysis of cross-sectional survey

OBJECTIVES

This study investigates caesarian section (CS) and vaginal delivery disparity, impact and contributions to timely initiation of breastfeeding (TIBF) to guide evidence-based strategy for improved breastfeeding practice.

DESIGN AND SETTINGS

A cross-sectional (population-based) analysis of 19 101 non-missing breastfeeding data from the 2018 Nigerian Demographic Health Survey collected via a two-stage stratified-random sampling across the 37 states in the 6 geopolitical-zones of Nigeria.

PARTICIPANTS

Complete responses from reproductive-age women (15-49 years) who had at least a childbirth in the last 5 years prior to the 2018 survey.

MAIN OUTCOME MEASURES

TIBF, that is, breastfeeding initiation within the first hour of newborn life is the outcome, CS is the exposure variable and explanatory factors were classified as; socio-demographic and obstetrics.

METHODS

Descriptive statistics were reported and graphically presented. Bivariate χ2 analysis initially assessed the relationship. Crude and adjusted logistic regression evaluated the likelihood and significance of multivariable association. Multivariate decomposition further quantified predictors' contribution and importance. Statistical analysis was performed at a 95% confidence level in Stata V.17.

RESULTS

44.1% and 20.2% of women with vaginal and CS delivery observed TIBF, respectively. Odds of TIBF were five times lower in women with CS delivery (adjusted OR 'AOR'=0.21: 95% CI=0.16 to 0.26). TIBF odds increase among women who used skilled prenatal provider (AOR=1.29: 95% CI=1.15 to 1.45), had hospital delivery (AOR=1.34: 95% CI=1.18 to 1.52) and in rich wealth class (AOR=1.44: 95% CI=1.29 to 1.60), respectively. Rural residency, unwanted pregnancy and large child size at birth however reduces the odds. Partial skin-to-skin contacts contributed to about 54% (p<0.05) of the negative effect. TIBF is highest in Kano (3.4%) and lowest in Taraba (0.02%) with topmost impact in Bayelsa state (crude OR 'COR'=63.9: 95% CI=28.2 to 144.9).

CONCLUSIONS

CS exposure reduced the odds of TIBF by fivefolds. Hence, the adverse effect of CS exposure on TIBF. Skin-to-skin contact can reduce the negative effect of CS on TIBF. Early mother-child contact peculiar to CS women is critical for improved breastfeeding practice.

Birth Preparedness and Complication Readiness among Antenatal Attendees in a Tertiary Hospital in Northern Nigeria

Background and Objective

Every expectant mother is at risk of complications during pregnancy, delivery, or after delivery. Delays in receiving care with accompanying maternal morbidity and mortality can be significantly reduced with adequate birth preparedness and complication readiness (BPCR). This study aims to determine the factors affecting BPCR among antenatal attendees in Gusau, Zamfara State, a security-challenged setting.

Methods

A cross-sectional study was conducted among pregnant women attending the antenatal clinic at Federal Medical Center, Gusau, Nigeria. Data were collected using a pretested questionnaire and analyzed using the Statistical Package for Social Sciences (SPSS) Version 26. Descriptive data using means, percentages, and frequency were presented in tables. Statistical testing using Chi-square for bivariate analysis and binary logistic regression for multivariate analysis was carried out with a significance level of p < 0.05.

Results

One hundred and forty-seven women were recruited; 111 (75.5%) had good knowledge of the danger signs of pregnancy, labor, and the postpartum period. One hundred and fourteen (77.6%) were birth-prepared and complications-ready. One hundred and ten (75%) identified insecurity as the most important hindrance to BPCR. The respondents with higher educational levels were thrice more likely to be birth-prepared and complications-ready (OR: 2.95, 95% CI: [1.65-5.27]). The women were twice more likely to be birth-prepared and complications-ready with an increase of ₦20,000 ($46.3) in monthly income (OR: 2.53, 95% CI: 1.97-5.29).

Conclusion and Global Health Implications

Education and wealth status are the key determinants of BPCR. Low educational status, financial constraints, and security challenges were identified as barriers that must be addressed to improve maternal and infant well-being.

Factors contributing to household wealth inequality in under-five deaths in low- and middle-income countries: decomposition analysis

BACKGROUND

The burden of under-5 deaths is disproportionately high among poor households relative to economically viable ones in developing countries. Despite this, the factors driving this inequality has not been well explored. This study decomposed the contributions of the factors associated with wealth inequalities in under-5 deaths in low- and middle-income countries (LMICs).

METHODS

We analysed data of 856,987 children from 66,495 neighbourhoods across 59 LMICs spanning recent Demographic and Health Surveys (2010-2018). Under-5 mortality was described as deaths among live births within 0 to 59 months of birth and it was treated as a dichotomous variable (dead or alive). The prevalence of under-five deaths was stratified using household wealth status. A Fairlie decomposition analysis was utilized to investigate the relative contribution of the factors associated with household wealth inequality in under-5 deaths at p<0.05. The WHO health equity assessment toolkit Plus was used to assess the differences (D) ratios (R), population attributable risk (PAR), and population attributable fraction (PAF) in household wealth inequalities across the countries.

RESULTS

The proportion of children from poor households was 45%. The prevalence of under-5 deaths in all samples was 51 per 1000 children, with 60 per 1000 and 44 per 1000 among children from poor and non-poor households (p<0.001). The prevalence of under-5 deaths was higher among children from poor households than those from non-poor households in all countries except in Ethiopia, Tanzania, Zambia, Lesotho, Gambia and Sierra Leone, and in the Maldives. Thirty-four of the 59 countries showed significantly higher under-5 deaths in poor households than in non-poor households (pro-non-poor inequality) and no significant pro-poor inequality. Rural-urban contexts, maternal education, neighborhood socioeconomic status, sex of the child, toilet kinds, birth weight and preceding birth intervals, and sources of drinking water are the most significant drivers of pro-poor inequities in under-5 deaths in these countries.

CONCLUSIONS

Individual-level and neighbourhood-level factors were associated with a high prevalence of under-5 deaths among poor households in LMICs. Interventions in countries should focus on reducing the gap between the poor and the rich as well as improve the education and livelihood of disadvantaged people.

Multivariate decomposition of trends, inequalities and predictors of skilled birth attendants utilisation in Nigeria (1990-2018): a cross-sectional analysis of change drivers

OBJECTIVES

Literature has assessed skilled birth attendants (SBAs) utilisation, but little is known about what contributes to the changes in SBA use. Multivariate decomposition analysis was thus applied in this study to examine; levels, trends, inequalities and drivers of changes in SBA utilisation.

DESIGN AND SETTING

A cross-sectional analysis of five-waves of NDHS-data (1990, 2003, 2008, 2013, and 2018), collected through similar multistage sampling across the 36 states and the federal-capital-territory of Nigeria.

PARTICIPANTS

Women of reproductive age (15-49 years), and with at least one birth in the last 5 years preceding each of the surveys.

MAIN OUTCOME MEASURE

SBA use is the response variable while explanatory variables were classified into; Demographics, Health, Economic and Corporal factors.

METHODS

Chi-square test for trends of proportions across the ordered survey years assessed trends in SBA use. MDA that quantifies and partition predictors effect into endowment and coefficient components evaluated contributors to changes in SBA use. Statistical analysis was carried out at a 95% confidence interval in Stata 16.

RESULTS

SBA use increased with significant (p<0.05) linear trends by 12% between 2003 and 2018. The decomposition analysis showed that differences in characteristics (endowment) accounted for 11.5% of the changes while the remaining 88.5% were due to differences in effects (coefficient). SBA utilisation rises by 61% when respondents decided on her health compared to when such decisions were made by the spouse. Utilisation of SBA, however, fell by 88% among women who reside in the states with high rural populations percentage.

CONCLUSIONS

SBA use remained low in Nigeria, and slowly increase at the rate of <1% yearly. Women health decision-making power contributed most to positive changes. Residing in states with high rural populations has a negative impact on SBA use. Maternal health programmes that strengthen women's health autonomy and capacity building in rural communities should be encouraged.
