Comment on paper by Cohen, Patel, Thara, and Gureje.

摘要

I agree with the authors' criticism of the use of the dichotomy between developed and developing countries, partly because of the difficulty in defining these terms and partly due to the myriad different social, cultural, and economic factors subsumed by them. While "low income" and "middb Income" can be reasonably accurately defined, they also encompass a great diversity of factors, both within and between countries. In addition, the authors have aggregated 23 studies including prevalence and incidence samples and prospective and retrospective designs.
