Low Birth Weight - Continued

Variations between and within geographic regions remain considerable and have not greatly changed (Table 1). The incidence of LBW, by region, ranges from 31.1% in Middle South Asia and 19.7% for Asia as a whole to 14.0% in Africa, 10.1% in Latin America, 6.8% in North America, and 6.5% in Europe.

In Africa, the estimated percentage of LBW infants for 1982 is 14.0%, 1% lower than that for 1979. This decrease is largely due to changes in Northern and Southern Africa, where more recent data have changed the estimates for a number of countries, including Egypt and Lesotho. There is no evidence of substantive changes in Eastern and Western Africa, with the possible exception of Kenya which has improved, and Rwanda and the United Republic of Tanzania which have deteriorated. New information is available for a number of countries in these regions, but national rates are all between 10% and 20%. The only change found for Middle Africa was a slight deterioration for Cameroon.
