[Logistic regression of the environmental risk factors in areas with Kashin-Beck disease].
OBJECTIVE
In order to find the factors influencing the prevalence of KBD, the possible nosogenetic factors of the family in Kashin-Beck disease (KBD) areas were analyzed.


METHODS
The possible nosogenetic factors in mild, middle, high prevalence KBD areas were analyzed by logistic regression. The differences of the factors between three kinds of KBD areas were compared.


RESULTS
Univariate analysis found sanitary conditions and meat-egg-mild were associated with KBD prevalence in all kinds KBD areas. Binary logistic analysis of multivariate suggested the possible nosogenetic factors were different in the different kind of KBD areas. It was wheat in mild prevalence area, sanitary conditions and meat-egg-mild in middle prevalence area, and sanitary conditions, rice and meat-egg-mild in high prevalence area.


CONCLUSIONS
The risk factors are associated with the kind of KBD areas. The different preventive methods should be taken according to the kind of KBD areas, which will improve the effect of prevention.
