Decomposing Wealth-Based Inequalities in Under-Five Mortality in West Africa.

BACKGROUND: This study aimed to analysis the inequalities of mortality of children under 5 years in West Africa by examining the determinants and contributing factors to the overall inequality concentration in these countries. METHOD: Data used came from the DHS surveys conducted in the six countries in West Africa: Burkina Faso (2010), Benin (2006), Cote d'Ivoire 2011), Ghana (2008), Mali (2006), Nigeria (2008) and Niger (2012). The concentration index (CI) and Generalized Linear Model (GLM) with logit link were used to access inequality. RESULTS: The results show that in all countries, the poorest Q1 have the highest proportions of deaths: Nigeria (31.4%), Cote d'Ivoire (30.4%) and Ghana (36.4%), over 30% of deaths of children under 5 years are among the children of the poorest (Q1) and the absolute differences of proportions Q1-Q5 are more than 20 points (25.8 in Ghana and 23.6 in Nigeria). The contributing factors of inequalities of child mortality were birth order, maternal age, parity and household size. Our findings also showed that the intensity of inequality varies from one country to another. CONCLUSION: The most important conclusion of this study is to reduce mortality in children under 5 years, it is needed to reduce economic and social inequalities and improve the country's economic and social condition. There is a need for monitoring and assessment inequalities by leading causes of death and morbidity among children in the region in order to advance in understanding the gaps and finding a way to reduce them in West Africa countries.

TB/HIV risk factors identified from a General Household Survey of South Africa in 2006.

The level of human immunodeficiency virus (HIV), tuberculosis (TB) as well as the co-infection TB/HIV in South Africa is among the highest in the world. TB is curable while HIV is not, yet the combination of both is a growing feature in the world. This study examined TB and HIV affecting people living in South Africa. Analyses have been undertaken based on data from the General Household Survey of South Africa in 2006. The study focused on respondents aged 15-49 years, corresponding to a total of 55,384 people composed of 25,859 males and 29,525 females. Among this population, 5935 people suffered from illness/injury, including 2469 (41.6%) males and 3466 (58.4%) females. Weighted multivariate logistic regression is performed on TB and/or HIV in association with the province, background characteristics of the target population, and selected socioeconomic and demographic variables included in the survey. In this study we focus on variables of health status and whether subjects suffered from TB and/or HIV. Findings of this investigation show that TB is the second most common cause of illness in the provinces of KwaZulu-Natal (KN) (9.1%), North West (5.4%) and Limpopo (4.2%). People who are married have a 50% lower risk compared to those currently not married to suffer from TB and/or HIV. Those with living spouses have a 5% lower risk to suffer from TB and/or HIV than those whose partners are not alive. This study concluded that rapid action is needed to curb the spread of TB and/or HIV to produce a healthy population. Therefore, follow-up care and special preventative measures are urgently needed in provinces with higher reported rates of TB and/or HIV such as KN.

Maternal Mortality in Burkina Faso: A Method from Population Census 2006.

BACKGROUND: Estimating maternal mortality level is constantly challenging researchers and planners both in rich and poor countries. In developing countries, particularly in Burkina Faso where the registration system is not working properly, censuses and surveys are the main providers of maternal mortality estimates. However, censuses provide more reliable data about maternal mortality especially at sub-national level. Strength of this situation, the census 2006 of Burkina Faso collected information about maternal mortality. Unfortunately, the census also under reported the phenomenon. In this regard, a methodology was developed to provide adjusted estimates of the phenomenon. METHODS: This paper aims to assess the census 2006 estimates of maternal mortality through a critical review of the questionnaire, data quality, adjustment technique and outputs. Incoherencies, duplicated cases and missing data were the key aspects of the data quality assessment. The assumptions and outputs of the method were examined and comparison made with existent estimates. RESULTS: Findings highlighted weaknesses regarding the assumptions of the method and showed that the levels of the phenomenon were still under-estimated. In this research, propositions have been made concerning data cleaning, situations of adjustment coefficients less than 1 and the problem of weak assumptions. Findings led to a MMRatio of 331 [293-402] maternal deaths per 100 000 live births. CONCLUSION: The level of maternal mortality as published in the census 2006 report (MMRatio of 307) is acceptable because falling in the range 293-402. However, the questionnaire, data and method used needed improvements.
