Usefulness of Growth Measurements for Preventing Obesity After Birth

中西, 増代

内容記述
The objective of the present study is to investigate the usefulness of growth measurements for preventing obesity based on the onset of adiposity rebound (AR) and the characteristics of allometry as determined from body mass index (BMI) measurements taken after birth. The height, body weight, and BMI of 18 one-year-old children at a nursery school(14 boys, 4 girls) were monitored. A quadratic equation was applied to the obtained BMI, and the lowest point was taken to be the age at AR. An allometric equation between the logarithms of height and body weight was derived, and its slope was determined. Based on the results, subjects were classified into type A, in which the BMI after birth changed along the percentile curve for standard values, and type B, in which the BMI decreased by changing from a high-percentile curve to a low-percentile curve. Age at AR was lower for subjects at or above the 75th percentile compared to those below the 75th percentile. In addition, subjects with a steep slope for the allometric equation tended to be type A. The key finding was that monitoring allometry, rather than age at AR alone, is also necessary in order to prevent future obesity.
