Between 1983 and 1987 over 99% of all infants born in England and Wales had their birth weights recorded when the birth was registered. Trends in occurrence and one year survival of those who weighed under 1500 g at birth have been calculated in 100 g groups, separately for single and multiple births. By 1987 singleton live births in England and Wales who weighed between 700 and 799 g had a 43% chance of surviving to 1 year compared with a 32% chance five years earlier; those who weighed 800 to 899 g had a 55% chance compared with 46%. The absolute number of survivors weighing between 500 and 999 g at birth increased by nearly 50% between 1983 and 1987, and there was a 30% increase overall in survivors weighing less than 1500 g.
1983年至1987年间，在英格兰和威尔士出生的所有婴儿中，超过99%在出生登记时记录了出生体重。已按100克分组计算了出生时体重低于1500克的婴儿的发生率和1岁生存率趋势，单胎和多胎分别计算。到1987年，英格兰和威尔士出生体重在700至799克之间的单胎活产婴儿活到1岁的几率为43%，而五年前为32%；体重在800至899克之间的婴儿活到1岁的几率为55%，而五年前为46%。1983年至1987年间，出生时体重在500至999克之间的存活婴儿绝对数量增加了近50%，体重低于1500克的存活婴儿总数增加了30%。
