Limited Progress in Increasing Coverage of Neonatal and Child-health Interventions in Africa and Asia

The study was conducted to analyze recent trends in the coverage of selected child-survival interventions. A systematic analysis of the coverage of six key child-health interventions in 29 African and Asian countries that had two recent demographic and health surveys—the latest one carried out in 2001 onwards and the immediately preceding survey conducted after 1990—was undertaken. A regression model was used for examining the relationship between the changes in the coverage of interventions and the changes in rates of mortality among children aged less than five years (under-five mortality). A limited increase in the coverage of key child-health interventions occurred in the past 5–10 years in these 29 countries in sub-Saharan Africa and Asia. More than half of the countries had no significant improvement or a significant reduction in the coverage of oral rehydration therapy (ORT) for diarrhoea (17/29) and care-seeking for acute respiratory infection (ARI) (16/29). Results of multivariate analysis revealed that increases in the coverage of early initiation of breastfeeding, ORT for diarrhoea, and care-seeking for ARI were significantly associated with reductions in under-five mortality. The results of this analysis should serve as a wake-up call for policy-makers and programme managers in countries, donors, and international agencies to accelerate efforts to increase the coverage of key child-survival interventions. The following three main actions are proposed: setting of the clear target; mobilization of resources for increasing skilled birth attendants and health workers trained in integrated management of childhood illness; and implementation of community-based approaches

Global and regional estimates of cancer mortality and incidence by site: I. Application of regional cancer survival model to estimate cancer mortality distribution by site

BACKGROUND: The Global Burden of Disease 2000 (GBD 2000) study starts from an analysis of the overall mortality envelope in order to ensure that the cause-specific estimates add to the total all cause mortality by age and sex. For regions where information on the distribution of cancer deaths is not available, a site-specific survival model was developed to estimate the distribution of cancer deaths by site. METHODS: An age-period-cohort model of cancer survival was developed based on data from the Surveillance, Epidemiology, and End Results (SEER). The model was further adjusted for the level of economic development in each region. Combined with the available incidence data, cancer death distributions were estimated and the model estimates were validated against vital registration data from regions other than the United States. RESULTS: Comparison with cancer mortality distribution from vital registration confirmed the validity of this approach. The model also yielded the cancer mortality distribution which is consistent with the estimates based on regional cancer registries. There was a significant variation in relative interval survival across regions, in particular for cancers of bladder, breast, melanoma of the skin, prostate and haematological malignancies. Moderate variations were observed among cancers of colon, rectum, and uterus. Cancers with very poor prognosis such as liver, lung, and pancreas cancers showed very small variations across the regions. CONCLUSIONS: The survival model presented here offers a new approach to the calculation of the distribution of deaths for areas where mortality data are either scarce or unavailable

Data collection tools for maternal and child health in humanitarian emergencies: a systematic review

OBJECTIVE: To describe tools used for the assessment of maternal and child health issues in humanitarian emergency settings. METHODS: We systematically searched MEDLINE, Web of Knowledge and POPLINE databases for studies published between January 2000 and June 2014. We also searched the websites of organizations active in humanitarian emergencies. We included studies reporting the development or use of data collection tools concerning the health of women and children in humanitarian emergencies. We used narrative synthesis to summarize the studies. FINDINGS: We identified 100 studies: 80 reported on conflict situations and 20 followed natural disasters. Most studies (76/100) focused on the health status of the affected population while 24 focused on the availability and coverage of health services. Of 17 different data collection tools identified, 14 focused on sexual and reproductive health, nine concerned maternal, newborn and child health and four were used to collect information on sexual or gender-based violence. Sixty-nine studies were done for monitoring and evaluation purposes, 18 for advocacy, seven for operational research and six for needs assessment. CONCLUSION: Practical and effective means of data collection are needed to inform life-saving actions in humanitarian emergencies. There are a wide variety of tools available, not all of which have been used in the field. A simplified, standardized tool should be developed for assessment of health issues in the early stages of humanitarian emergencies. A cluster approach is recommended, in partnership with operational researchers and humanitarian agencies, coordinated by the World Health Organization

The effect of Haemophilus influenzae type b and pneumococcal conjugate vaccines on childhood pneumonia incidence, severe morbidity and mortality

Background With the aim of populating the Lives Saved Tool (LiST) with parameters of effectiveness of existing interventions, we conducted a systematic review of the literature assessing the effect of Haemophilus influenzae type b (Hib) and pneumococcal (PC) conjugate vaccines on incidence, severe morbidity and mortality from childhood pneumonia. Methods We summarized cluster randomized controlled trials (cRCTs) and case-control studies of Hib conjugate vaccines and RCTs of 9- and 11-valent PC conjugate vaccines conducted in developing countries across outcome measures using standard meta-analysis methods. We used a set of standardized rules developed for the purpose of populating the LiST tool with required parameters to promote comparability across reviews of interventions against the major causes of childhood mortality. The estimates could be adjusted further to account for factors such as PC vaccine serotype content, PC serotype distribution and human immunodeficiency virus prevalence but this was not included as part of the LiST model approach. Results The available evidence from published data points to a summary effect of the Hib conjugate vaccine on clinical pneumonia of 4%, on clinical severe pneumonia of 6% and on radiologically confirmed pneumonia of 18%. Respective effectiveness estimates for PC vaccines (all valent) on clinical pneumonia is 7%, clinical severe pneumonia is 7% and radiologically confirmed pneumonia is 26%. Conclusions The findings indicated that radiologically confirmed pneumonia, as a severe morbidity proxy for mortality, provided better estimates for the LiST model of effect of interventions on mortality reduction than did other outcomes evaluated. The LiST model will use this to estimate the pneumonia mortality reduction which might be observed when scaling up Hib and PC conjugate vaccination in the context of an overall package of child health intervention

Tendência das desigualdades sociodemográficas no pré-natal na Baixada Litorânea do estado do Rio de Janeiro, 2000-2020: um estudo ecológico

Objective: To analyze trends of sociodemographic inequalities in access and utilization of prenatal care in the ‘Baixada Litorânea’ of Rio de Janeiro, 2000-2020. Methods: Ecological study –Time series – of number of visits and adequacy of access to prenatal care. Absolute (differences) and relative (ratios) inequalities were estimated between extreme variable categories. Trends were estimated by Joinpoint regression. Results: 185,242 women were studied. The proportion of ≥7 visits increased, 2.9% (CI95% 0.7;5.1), annually, between 2013 (54.4%) and 2020 (64.7%), stable for women with < 8 years of education. Adequacy of access increased 2.6% (CI95% 1.2;4.0), stable in ≥35 years-old women, and in those with ≥12 years of education. Absolute inequalities decreased (from 3.5 to 6.4%) for age and skin color, and relative inequalities (from 7.7 to 20.0%) for all variables. Conclusion: Access and number of visits increased, but persisted lower for adolescents, women with low-education, and who self-reported skin color/race brown/black women.Objetivo: Analizar la tendencia de las desigualdades sociodemográficas en el acceso y uso de la atención prenatal (APN) en la ‘Baixada Litorânea’ en Rio de Janeiro, 2000/2020.

Revitalizing child health: lessons from the past

Essential health, education and other service disruptions arising from the COVID-19 pandemic risk reversing some of the hard-won gains in improving child survival over the past 40 years. Although children have milder symptoms of COVID-19 disease than adults, pandemic control measures in many countries have disrupted health, education and other services for children, often leaving them without access to birth and postnatal care, vaccinations and early childhood preventive and treatment services. These disruptions mean that the SARS-CoV-2 virus, along with climate change and shifting epidemiological and demographic patterns, are challenging the survival gains that we have seen over the past 40 years. We revisit the initiatives and actions of the past that catalyzed survival improvements in an effort to learn how to maintain these gains even in the face of today's global challenges

Diarrhea incidence in low- and middle-income countries in 1990 and 2010: a systematic review

<p>Abstract</p> <p>Background</p> <p>Diarrhea is recognized as a leading cause of morbidity and mortality among children under 5 years of age in low- and middle-income countries yet updated estimates of diarrhea incidence by age for these countries are greatly needed. We conducted a systematic literature review to identify cohort studies that sought to quantify diarrhea incidence among any age group of children 0-59 mo of age.</p> <p>Methods</p> <p>We used the Expectation-Maximization algorithm as a part of a two-stage regression model to handle diverse age data and overall incidence rate variation by study to generate country specific incidence rates for low- and middle-income countries for 1990 and 2010. We then calculated regional incidence rates and uncertainty ranges using the bootstrap method, and estimated the total number of episodes for children 0-59 mo of age in 1990 and 2010.</p> <p>Results</p> <p>We estimate that incidence has declined from 3.4 episodes/child year in 1990 to 2.9 episodes/child year in 2010. As was the case previously, incidence rates are highest among infants 6-11 mo of age; 4.5 episodes/child year in 2010. Among these 139 countries there were nearly 1.9 billion episodes of childhood diarrhea in 1990 and nearly 1.7 billion episodes in 2010.</p> <p>Conclusions</p> <p>Although our results indicate that diarrhea incidence rates may be declining slightly, the total burden on the health of each child due to multiple episodes per year is tremendous and additional funds are needed to improve both prevention and treatment practices in low- and middle-income countries.</p
