[Quantitative epidemiological investigation on social, economic and geographic factors contributing to falciparum malaria in southern Henan province].
A case-control study was conducted at Xinyang prefecture, Henan province in 1988 to investigate social, economic and geographic factors believed to be associated with the occurrence of residual falciparum malaria cases. Data were obtained from 65 residual cases and 195 matched control samples from neighbours, residents in the same village and extravillage. The questionnaire contained a total of 27 relevant items. The results of analysis of conditional logistic multi-regression model with IBM PC/XT microcomputer showed that six important risk factors related to residual falciparum malaria cases, i.e., the type of breeding places, yellow-brown soil, the knowledge of malaria transmission, open-sleep habit, family's malaria history and number of livestock. The epidemiological significance of these findings was discussed briefly.
