One of the articles in the Alma-Ata series in The Lancet in 2008 was on community participation, and I think it's a reflection of the growing recognition of what's been missing in so much of global health work which is a real partnership with the community and a real engagement of the community, and the enormous benefits that can come from community empowerment and womens' empowerment for the sake of health in a technical and real medical kind of way, and the randomized control trial that I mentioned reported in t he Lancet from community participatory women's groups is one of many examples now, of the power of this approach.
