To use Pea Pod, a device based on air displacement plethysmography, to study body composition of healthy, full-term infants born to well-nourished women with a western life-style.
Body composition was assessed in 53 girls and 55 boys at 1 week (before 10 days of age) and at 12 weeks (between 77 and 91 days of age).
At 1 week girls contained 13.4 +/- 3.7% body fat and boys 12.5 +/- 4.0%. At 12 weeks, these figures were 26.3 +/- 4.2% (girls) and 26.4 +/- 5.1% (boys). Body fat (%) did not differ significantly between the genders. Body fat (%) at the two measurements was not correlated. At 1 week, the weight (r = 0.20, p = 0.044) and BMI (r = 0.26, p = 0.007) of the infants, but not their body fat (g, %) or fat free mass (g), correlated with BMI before pregnancy in their mothers.
Pea Pod has potential for use in studies investigating the effect of external (i.e. nutritional status) and internal (i.e. age, gender, gestational age at birth) factors on infant body composition. This may be of value when studying relationships between the nutritional situation during early life and adult health.
使用基于空气置换体积描记法的 Pea Pod 设备研究生活方式西化的营养良好的足月妇女所生健康婴儿的身体成分。
在 1 周（<10 天龄前）和 12 周（77-91 天龄之间）时，对 53 名女婴和 55 名男婴进行身体成分评估。
1 周龄时，女婴的体脂含量为 13.4±3.7%，男婴为 12.5±4.0%。12 周龄时，这些数字分别为 26.3±4.2%（女婴）和 26.4±5.1%（男婴）。性别之间体脂（%）无显著差异。两次测量的体脂（%）之间没有相关性。1 周龄时，婴儿的体重（r=0.20，p=0.044）和 BMI（r=0.26，p=0.007），但不是体脂肪（g，%）或去脂体重（g），与母亲妊娠前 BMI 相关。
Pea Pod 可用于研究外部（即营养状况）和内部（即年龄、性别、出生时的胎龄）因素对婴儿身体成分的影响。当研究生命早期营养状况与成人健康之间的关系时，这可能具有重要价值。
