HIV-1 incidence has been increasing more rapidly in the Middle East and North Africa than in any other global region. Despite this trend, HIV epidemiology in the region remains poorly defined. We conducted an analysis of 3284 publicly available HIV-1 sequences from 15 countries in the Middle East and North Africa to better characterize the regional epidemic. A phylogenetic tree based on the rev...
Berbers live in groups scattered across North Africa whose origins and genetic relationships with their neighbours are not well established. The first hypervariable segment of the mitochondrial DNA (mtDNA) control region was sequenced in a total of 155 individuals from three Tunisian Berber groups and compared to other North Africans. The mtDNA lineages found belong to a common set of mtDNA hap...

Drosophila melanogaster spread from sub-Saharan Africa to the rest of the world colonizing new environments. Here, we modeled the joint demography of African (Zimbabwe), European (The Netherlands), and North American (North Carolina) populations using an approximate Bayesian computation (ABC) approach. By testing different models (including scenarios with continuous migration), we found that ad...
This paper investigates whether there is gender bias in the duration that children are breastfed in Africa. Given evidence that breastfeeding is negatively related to future fertility, we further investigate whether any part of the gender bias is due to son preference in fertility choice. We use identical methodology to Jayachandran and Kuziemko (2010), and compare our results on Africa to thei...
Human population movements in North Africa have been mostly restricted to an east-west direction due to the geographical barriers imposed by the Sahara Desert and the Mediterranean Sea. Although these barriers have not completely impeded human migrations, genetic studies have shown that an east-west genetic gradient exists. However, the lack of genetic information of certain geographical areas ...
OBJECTIVES Inhabitants of developing countries such as those in North Africa have experienced lifestyle changes that have increased the risk of cardiovascular disease. The aim of the Epidemiological Trial of Hypertension in North Africa (ETHNA) was to evaluate the prevalence and clinical profile of hypertension in a large sample of individuals in North Africa. METHODS This was an internationa...
