The 2001-03 Famine and the Dynamics of HIV in Malawi: A Natural Experiment
Fig 3
Change in prevalence of farmers at antenatal sites through the famine in relation to rural hunger.
The independent variable is the proportion of rural households estimated from a humanitarian survey to be in need of food assistance in December 2002-March 2003 in the district surrounding antenatal sites. The observed values of the dependent variable are the ratio of the proportion of farmers among the women attending antenatal clinics in 2003, after the worst of the famine, to the proportion in 1999/2000, prior to the rapid rise in food prices. The fitted values are from multilevel log binomial regression (model 3, S2 Table). (A) Rural sites; (B) Non-rural sites (squares: cities, triangles: towns, open triangle: Nsanje, which is included in the analysis).
