The report indicates that 5.6 million infant deaths and 2,000,000 maternal Deaths could be prevented this year if women chose to have theirs children ____3____ within the safest years with adequate intervals among births and limited their ____4____ families to moderate size. This amounts to about half of the 9.8 million infant and 370.000 maternal deaths in developing countries, excluded China, estimated for this year by ____5____ the United Nation?s Children?s Fund and the US Centers for Disease Control respectably.
