Mental disorders as risk factors: assessing the evidence for the Global Burden of Disease Study

Background: Mental disorders are associated with a considerable burden of disease as well as being risk factors for other health outcomes. The new Global Burden of Disease (GBD) Study will make estimates for both the disability and mortality directly associated with mental disorders, as well as the burden attributable to other health outcomes. Herein we discuss the process by which health outcomes in which mental disorders are risk factors are selected for inclusion in the GBD Study. We make suggestions for future research to strengthen the body of evidence for mental disorders as risk factors

Revisiting the 'Cotton Problem': A Comparative Analysis of Cotton Reforms in Sub-Saharan Africa

The cotton sector has been amongst the most regulated in Africa, and still is to a large extent in West and Central Africa (WCA), despite repeated refirm recommendations by international donors. On the other hand, orthodox refirms in East and Southern Africa (ESA) have not always yielded the expected results. This paper uses a stylised contracting model to investigate the link between market structure and equity and efficiency in sub-Saharan cotton sectors; explain the outcomes of refirms in ESA; and analyze the potential consequences of orthodox refirms in WCA. We argue that the level of the world price and of government intervention, the nature of pre-refirm institutional organisation, as well as the degree of parastatal inefficiency, all contribute to making refirms less attractive to firmers and governments in WCA today, as compared to ESA in the 1990s.We illustrate our arguments with empirical observations on the perfirmance of cotton sectors across sub-Saharan Africa

Patterns and Predictors of Language Development from 4 to 7 Years in Verbal Children With and Without Autism Spectrum Disorder

This study used a prospective community-based sample to describe patterns and predictors of language development from 4 to 7 years in verbal children (IQ ≥ 70) with autism spectrum disorder (ASD; n = 26–27). Children with typical language (TD; n = 858–861) and language impairment (LI; n = 119) were used for comparison. Children with ASD and LI had similar mean language scores that were lower on average than children with TD. Similar proportions across all groups had declining, increasing and stable patterns. Language progressed at a similar rate for all groups, with progress influenced by IQ and language ability at 4 years rather than social communication skills or diagnosis of ASD. These findings inform advice for parents about language prognosis in ASD.No Full Tex
