RESUMEN
BACKGROUND: Under-five mortality is still a major health issue in many developing countries like Tanzania. To achieve the Sustainable Development Goal target of ending preventable child deaths in Tanzania, a detailed understanding of the risk factors for under-five deaths is essential to guide targeted interventions. This study aimed to investigate trends and determinants of neonatal, post-neonatal, infant, child and under-five mortalities in Tanzania from 2004 to 2016. METHODS: The study used combined data from the 2004-2005, 2010 and 2015-2016 Tanzania Demographic and Health Surveys, with a sample of 25,951 singletons live births and 1585 under-five deaths. We calculated age-specific mortality rates, followed by an assessment of trends and determinants (community, socioeconomic, individual and health service) of neonatal, postneonatal, infant, child and under-five mortalities in Cox regression models. The models adjusted for potential confounders, clustering and sampling weights. RESULTS: Between 2004 and 2016, we found that neonatal mortality rate remained unchanged, while postneonatal mortality and child mortality rates have halved in Tanzania. Infant mortality and under-five mortality rates have also declined. Mothers who gave births through caesarean section, younger mothers (< 20 years), mothers who perceived their babies to be small or very small and those with fourth or higher birth rank and a short preceding birth interval (≤2 years) reported higher risk of neonatal, postneonatal and infant mortalities. CONCLUSION: Our study suggests that there was increased survival of children under-5 years in Tanzania driven by significant improvements in postneonatal, infant and child survival rates. However, there remains unfinished work in ending preventable child deaths in Tanzania.

Background: In Nigeria, diarrhoea contributes significantly to childhood morbidity and mortality, with suboptimal breastfeeding practices playing a key role. The present study aimed to report on diarrhoea deaths and disability-adjusted life years (DALYs) among children aged under five years attributable to suboptimal breastfeeding practices in Nigeria. Methods: This study used data from the Global Burden of Disease study 2016, which estimated mortality from diarrhoea in the Cause of Death Ensemble model. Suboptimal breastfeeding was assessed as a combination of non-exclusive breastfeeding and discontinued breastfeeding. The comparative risk assessment approach was used to estimate the attributable burden of diarrhoea deaths and DALYs due to suboptimal breastfeeding practices in the spatial-temporal Gaussian Process Regression tool. Results: In 2016, suboptimal breastfeeding practices accounted for an estimated 56.5% (95% uncertainty intervals [UI]: 47.5, 68.3) of diarrhoea deaths in the late neonatal period, 39.0% (31.0, 46.3) in post-neonatal period, 39.0% (31.3, 46.20) in infancy period and 22.8% (16.9, 29.9) in children aged under five years in Nigeria. In the same year, 22,371 (14,259, 32,746) total diarrhoea deaths in children under five years could be attributed to suboptimal breastfeeding practices. DALYs from diarrhoea attributable to suboptimal breastfeeding practices was 1.9 million (1.2, 2.8 million) among children under five years in 2016. Between 1990 and 2016, the proportion of children who died from diarrhoea due to suboptimal breastfeeding did not change substantially across all age groups in Nigeria. Conclusions: Suboptimal breastfeeding practices remain a significant contributor to diarrhoea mortality and disability among children under five years in Nigeria. The study builds on previously published works on breastfeeding practices in Nigeria and provides evidence to support calls for the scale-up of efforts to improve infant feeding outcomes and reduce diarrhoea burden in Nigeria.

Background: Exclusive breastfeeding (EBF) has important benefits for both the mother and child. In India, no nationwide studies have examined patterns of EBF in the past decade to inform national and subnational breastfeeding programmes. The present study aimed to investigate the regional prevalence and determinants of EBF in India. Methods: This study used a total weighted sample of 21,352 from the 2015-2016 India National Family Health Survey. EBF was measured as the proportion of infants 0-5 months of age who received breast milk as the only source of nourishment, based on mother's recall on feeds given to the infant 24 h before the survey. The prevalence of EBF and other breastfeeding patterns were estimated by region, and multivariable logistic regression that adjusted for clustering and sampling weights was used to investigate the association between the study factors (child, maternal, household, health service and community factors) and EBF by regional areas in India. Results: This study indicated that wide differences in the prevalence of EBF and other childhood feeding practices exist across regions of India, where Southern India had the highest EBF prevalence (79.2%) and the North-East reported the lowest (68.0%). EBF prevalence decreased with infant age, dropping faster in the South (43.7% at 5 months) compared to the North-East region (54.0% at 5 months). Similarly, substantial variations in key determinants of EBF were evident by region, where higher birth order was the only common factor associated with non-EBF across all regions. Key modifiable determinants of non-EBF included higher maternal education in the South and belonging to rich households in Central India, while those for EBF were higher maternal education in the Central region and frequent antenatal care (≥ 4) visits in Northern India. Conclusion: This study demonstrates wide variations in regional prevalence and determinants of EBF in India. Improving EBF participation in India would require multifaceted national and subnational efforts that include dedicated funds and the establishment of appropriate policy and interventions that are consistently monitored and evaluated.

RESUMEN
Antenatal care (ANC) reduces adverse health outcomes for both mother and baby during pregnancy and childbirth. The present study investigated the enablers and barriers to ANC service use among Indian women. The study used data on 183,091 women from the 2015-2016 India Demographic and Health Survey. Multivariate multinomial logistic regression models (using generalised linear latent and mixed models (GLLAMM) with the mlogit link and binomial family) that adjusted for clustering and sampling weights were used to investigate the association between the study factors and frequency of ANC service use. More than half (51.7%, 95% confidence interval (95% CI): 51.1-52.2%) of Indian women had four or more ANC visits, 31.7% (95% CI: 31.3-32.2%) had between one and three ANC visits, and 16.6% (95% CI: 16.3-17.0%) had no ANC visit. Higher household wealth status and parental education, belonging to other tribes or castes, a woman's autonomy to visit the health facility, residence in Southern India, and exposure to the media were enablers of the recommended ANC (≥4) visits. In contrast, lower household wealth, a lack of a woman's autonomy, and residence in East and Central India were barriers to appropriate ANC service use. Our study suggests that barriers to the recommended ANC service use in India can be amended by socioeconomic and health policy interventions, including improvements in education and social services, as well as community health education on the importance of ANC.

BACKGROUND: Following the successful implementation of the Millennium Development Goals (MDGs) strategy in Tanzania, improvements in child health indicators were observed. However, it remains unclear whether complementary feeding practices have improved given the renewed global agenda on child nutrition. This study investigated trends and socioeconomic and health service factors of complementary feeding practices in Tanzania for the period spanning from 2004 to2016. METHODS: The study was based on the Tanzania Demographic and Health Survey data for the years 2004-2005 (n = 2480), 2010 (n = 2275) and 2015-2016 (n = 2949) to estimate the trends in complementary feeding practices. Multivariate logistic regression models that adjusted for year of the survey, clustering and sampling weights were used to investigate the association between the modifiable study factors (socioeconomic and health service factors) and complementary feeding practices among children aged 6-23 months in Tanzania. RESULTS: Over the study period, minimum dietary diversity (MDD) and minimum acceptable diet (MAD) have worsened from 46% (95% confidence interval [95% CI] 41.5-50.7%) in 2004-2005 to 30% (95% CI 25.7-32.9%) in 2015-2016 and 16.9% (95% CI 14.9-18.9%) in 2004-2005 to 6.0% (95% CI 4.9-7.1%) in 2015-2016, respectively. Minimum meal frequency (MMF) remained unchanged, 37% in 2004-2005 and 2015-2016. The introduction of solid, semi-solid and soft foods improved from 79% (95% CI 74.5-83.9%) in 2004-2005 to 87% (95% CI 83.7-90.9%) in 2015-2016. Multivariate analyses revealed that higher maternal education and household wealth, mother's employment, health facility birthing and postnatal care (PNC) visit were associated with MDD, MAD and MMF. Traditional birth attendant-assisted births and PNC visits were associated with the introduction of complementary foods. In contrast, birthing in the health facility was associated with the delayed introduction of complementary foods. CONCLUSION: Between 2004 and 2016, the prevalence and determinants of complementary feeding practices varied in Tanzania. Improving complementary feeding practices is feasible in Tanzania given the renewed focus on child nutrition in the country. Child nutrition policy interventions should target all mothers, particularly mothers from low socioeconomic background and those with limited access to health services to maximise results.
RESUMEN
BACKGROUND: According to the World Health Organization, Nigeria is one of the countries with a high burden of tuberculosis (TB) worldwide. Improving the burden of TB among HIV-negative people would require comprehensive and up-to-date data to inform targeted policy actions in Nigeria. The study aimed to describe the incidence, prevalence, mortality, disability-adjusted life years (DALYs) and risk factors of tuberculosis in Nigeria between 1990 and 2016. METHODS: This study used the most recent data from the global burden of disease study 2016. TB deaths were estimated using the Cause of Death Ensemble model, while TB incidence, prevalence and DALYs, as well as years of life lost and years of life lived with disability were calculated in the DisMod-MR 2.1, a Bayesian meta-regression tool. Using a comparative risk assessment approach, TB burden attributable to risk factors was estimated in a spatial-temporal Gaussian Process Regression tool. RESULTS: In 2016, the prevalence of TB among HIV-negative people was 27% (95% uncertainty interval [95% UI] 23-31%) in Nigeria. TB incidence rate (new and relapse cases) was 158 per 100,000 people (95% UI; 128-193), while the total number of TB mortality was 39,933 deaths (95% UI; 30,488-55,039) in 2016. Between 2000 and 2016, the age-standardised prevalence and incidence rates of TB-HIV negative decreased by 20.0 and 87.6%, respectively. The age-standardised mortality rate also dropped by 191.6% over the same period. DALYs due to TB among HIV-negative Nigerians was high but varied across the age groups. Of the risk factors studied, alcohol use accounted for the highest number of TB deaths and DALYs, followed by diabetes and smoking in 2016. CONCLUSION: The study shows an improving trend in TB disease burden among HIV-negative individuals in Nigeria from 1990 to 2016. Despite this progress, this study suggests that additional efforts are still needed to ensure that Nigeria is not left behind in the current global strategy to end TB disease. Reducing TB disease burden in the country will require a multipronged approach that includes increased funding, health system strengthening and improved TB surveillance, as well as preventive efforts for alcohol use, smoking and diabetes.
