作者研究了短（12个月间隔）的影响和人群水平的影响，间隔<6个月的母亲极低（<1.5 kg）出生体重分娩的风险增加约50%至80%，极早产（<32周）分娩的风险增加30%至90%。Logistic回归分析显示，短间隔的不良影响减少了约10%，但在控制了母亲年龄、教育、产次、婚姻状况、产前护理、吸烟和既往早产的潜在混杂因素后，大部分仍显着。
The authors studied the effects and population-level impact of short (12-month intervals, mothers with <6-month intervals had an approximately 50% to 80% increased risk of very low (<1.5 kg) birth weight delivery and a 30% to 90% increased risk of very preterm (<32 weeks) delivery. Logistic regression analyses showed that the adverse effects of short intervals were reduced by about 10% but remained for the most part significant after controlling for potential confounding by maternal age, education, parity, marital status, prenatal care, smoking, and previous preterm delivery.
