Under-five mortality and maternal HIV status in Tanzania: analysis of trends between 2003 and 2012 using AIDS Indicator Survey data

Zero-inflated Poisson regression analysis of factors associated with under-five mortality in Ethiopia using 2019 Ethiopian mini demographic and health survey data

BACKGROUND

Remarkable reduction in global under-five mortality has been seen over the past two decades. However, Ethiopia is among the five countries which account for about half (49%) of all under-five mortality worldwide. This study aimed at identifying factors associated with under-five children mortality in Ethiopia using the 2019 Ethiopia mini demography and health survey data.

METHODS

The most recent national representative demography and health survey data of Ethiopia, 2019 Ethiopia mini demography and health survey data, were used for this study. Count data regression models were applied to identify the factors associated with under-five children mortality. Statistical significance was declared at P-value less than 0.05.

RESULTS

Zero-Inflated Poisson (ZIP) regression model was found to be the best model compared to other count regression models based on models comparison Criteria. The ZIP model revealed that decreased risk of under-five mortality was associated with mothers aged 25-34 years, unmarried mothers, mothers delivered in health facility, mothers used Pill/IUD, mothers who had larger number of children at home whereas increased risk of under-five mortality was associated with older mothers at their first births, mothers from rural areas, mothers travel for 1-30 min and >30 min to get drinking water, mothers used charcoal and wood, children with higher birth order and multiple births.

CONCLUSIONS

In this study, place of residence, region, place of delivery, religion, age of mother, mother's age at first birth, marital status, birth order, birth type, current contraceptive type used, type of cooking fuel, time to get drinking water, and number of children at home were statistically significant factors associated with under-five mortality in Ethiopia. Thus, the Ethiopian Ministry of Health and other concerned bodies are recommended to encourage mothers to deliver at health institutions, give awareness for mothers to use Pill/IUD contraceptive type, and facilitate rural areas to have electricity and drinking water near to homes so as to minimize the under-five mortality to achieve the sustainable development goal.

Survival time and predictors of death among HIV infected under five children after initiation of anti -retroviral therapy in West Amhara Referral Hospitals, Northwest Ethiopia

BACKGROUND

Acquired immune deficiency syndrome is an infectious disease caused by the human immunodeficiency virus (HIV) that primarily targets an individual's immune system. In Ethiopia, nearly 24% of HIV-related deaths occur in children under the age of five. However, studies regarding the survival time of HIV-positive under-five children after anti-retroviral therapy initiation are limited with poor evidence of predictors of death.

OBJECTIVE

To assess survival time and predictors of death among HIV infected under-five children after initiation of anti-retroviral therapy in West Amhara Referral Hospitals, Northwest Ethiopia, 2021.

METHODS

A multicenter institution-based retrospective follow-up study was conducted among 432 HIV-positive under-five children on anti-retroviral therapy selected by simple random sampling from January 2010 to December 2019. A standardized data extraction tool was employed, which was adapted from anti-retroviral therapy entry and follow-up forms. The event of interest for this study is death, whereas the absence of experience of death is censored. Data were entered into Epi-Data version 3.1 and exported to STATA version 14. The Kaplan-Meier curve was used to estimate the survival probability. The Cox regression model was used to identify independent predictors of death.

RESULTS

Among the 415 records included in the final analysis, 25 (6.02%) of the individuals were died. The incidence rate of death was found to be 2.87 per 1000 child-months (95%CI: 1.94-4.25). The cumulative survival probabilities of children after 6, 12, 24, and 36 months were 0.97, 0.95, 0.92, and 0.85 respectively. HIV-infected under-five children who lived in rural areas (AHR 3.32:-95% CI 1.17-9.39), with poor adherence to anti-retroviral therapy (AHR = 3.36; CI: 1.06, 10.69), without Isoniazide prophylaxis (AHR = 3.15; CI: 1.11, 8.94) and with anemia (AHR: 3.05, 95% CI: 1.16, 8.03) were at higher risk of death.

CONCLUSION AND RECOMMENDATION

Death of HIV-infected under-five children on anti-retroviral therapy is high within the first one year after enrolment. Living in rural area, had poor adherence, lacked Isoniazide prophylaxis, and anemia were predictors of death. Therefore, clinicians shall emphasize for those specific risk factors of death and take action accordingly.

Socio-economic factors affecting high infant and child mortality rates in selected African countries: does globalisation play any role?

Background

Despite the declining trends worldwide, infant and child mortality rates are still high in many African countries. These high rates are problematic; therefore, this study attempts to explore the contributing factors that cause high infant and child mortality rates in 14 African countries using panel data for the period of 2000–2018. In particular, the role globalisation is explored.

Methods

The panel corrected standard error (PCSE), the Feasible generalized least square (FGLS) models, and the pair-wise Granger causality test have been applied as methodological approaches.

Results

The public health expenditure, numbers of physicians, globalization, economic development, education, good governance, and HIV prevalence rate have been revealed as the determinants of infant and child mortality in these countries. All these variables except the HIV prevalence rate negatively affect the infant and child mortality rates, while the HIV prevalence rate is found to be positive. Bidirectional and unidirectional causal relationships between the variables are also attained.

Conclusions

Effective socio-economic policy priority with due consideration of globalization should be emphasized to reduce infant and child mortality rates in these countries.
