Long-term studies of chronic disease needed in Africa
11-May-2010 - There is an urgent need for longitudinal cohorts based in sub-Saharan Africa to address the growing burden of non-communicable
diseases in the region, according to a new article published in PLoS Medicine. Michelle Holmes from the Channing Laboratory at Harvard Medical School and colleagues
argue that public health in sub-Saharan Africa has historically focused on communicable diseases including HIV/AIDS, malaria and other infectious disease.
However, non communicable diseases (NCDs), including cardiovascular diseases, mental illnesses, trauma, cancer, and diabetes, are now major sources
of morbidity and mortality in the region and are projected to overtake infectious diseases by 2030. The authors point out that prospective cohort
studies can be used to study multiple complex diseases and risk factors simultaneously over an individual's lifetime, and that such studies
have proved crucial in understanding the etiology, course, and outcome of NCDs in other populations. They have also informed the design
of prevention programs. In addition, cohort studies provide an incomparable resource for the training of public health researchers.
Because the payoff from cohort studies continues-and often grows-over time, they are a long-term investment in public health,
and are relevant to the sub-Saharan region, say the authors.
