In the total population of infants with birth weight 500 g or more born in a Norwegian county (Vestfold) 1970-84 (n = 34,756), the incidence of low birth weight (500-2499 g) declined significantly, from 5\% during the 10-year period 1970-79, to 4.1\% during the 5-year period 1980-84 (p less than 0.01). The decline was stronger for very low birth weight infants (500-1499 g) than for moderately low birth weight infants (1500-2499 g) (31\% vs. 13\%; p less than 0.01). Perinatal mortality decreased from 17 to 10.3\% (p less than 0.01), and the incidence of CP from 2.6 to 2.1\% (p = 0.4). Because low birth weight infants were at increased risk for perinatal death and CP, the declining incidence of low birth weight was attributable 41.4\% of the decline in perinatal mortality, and 40\% of the reduction of CP from the period 1970-79 to 1980-84. Strategies for prevention of low birth weight may be important for further reduction of perinatal mortality and handicaps related to low birth weight.
