A STUDY ON THE EFFECTS OF EARLY AND COMPREHENSIVE PREVENTION OF RIC-KETS IN INFANTS AND TODDLERS

报道1987～1989年广西阳朔县佝偻病早期综合防治的效果.结果:(1)婴儿期早期综合防治后发病率比防治前下降了95.1%,病期均为轻型,与同期对照组比较,保护率为86.1%,三种投药法效果差别不大,采用每季投药法简便易行.(2)胎儿期投药预防效果不明显.(3)婴幼儿期综合防治后发病率比防治前下降了68.1%,病期也均属轻型.

The effects of early and comprehensive prevention (E.C.P) on rickets were reported with the following results: (1) The morbidity of rickets in the infant group after E.C.P was significantly lower than that before E.C.P, with a reduced rate of 95.1 percent.Although a few cases were still reported after E.C.P, all of them were very mild Comparing with the control group, the protective rate was 86.1 percent.There were no significant differences in the effects among the three VD administered groups (daily, monthly, and seasonly).But the seasonly VD administered method was more simple and convenient.(2)The E.C.P effect on the prevention of rickets in the fetus group was not significant.(3) In the infant-toddler group the morbidity of rickets after E.C.P was lower than that before E.C.P, with a reduced rate of 68.1 percent, and were of the mild type.This study suggests that a program of early and comprehensive prevention of rickets might provide a good economical and social benefit.
