In a previous study we reported that healthy children born at 34 or fewer gestational weeks, with adequate weight for gestational age, had not completed their bone catch-up at mean age of 6.3 years.
This is a follow up report, performed on the same population one year later to determine at which age premature - born children achieve their bone mineral density (BMD) catch-up, compared to term-born controls.
Fifteen children mean age 7 years 3 months, born at 25 to 34 weeks of gestation, with a birth weight of 740 to 2.200 g were studied Radius, lumbar spine and femoral neck bone mineral density, whole body bone mineral content and body composition were assessed by DEXA.
Height, body mass index, peripheral BMD, axial BMD, fat and lean body mass in these children were not different from term born controls.
Premature born children with adequate weight for gestational age, achieved peripheral and axial bone mineral density catch-up at the age of 7 to 8 years.
在之前的一项研究中，我们报告称，孕周为34周及以下且出生体重适合孕周的健康儿童，在6.3岁时其骨骼追赶生长尚未完成。
这是一份后续报告，一年后对同一人群进行研究，以确定与足月儿对照组相比，早产儿童在哪个年龄实现其骨矿物质密度（BMD）的追赶。
研究了15名平均年龄为7岁3个月的儿童，他们出生时孕周为25至34周，出生体重为740至2200克。通过双能X线吸收法（DEXA）评估桡骨、腰椎和股骨颈的骨矿物质密度、全身骨矿物质含量和身体成分。
这些儿童的身高、体重指数、外周骨密度、轴向骨密度、脂肪和瘦体重与足月儿对照组无差异。
出生体重适合孕周的早产儿童在7至8岁时实现了外周和轴向骨矿物质密度的追赶。
