The growth of the skull from birth till adulthood was studied among Gilbertese from Betio. With few exceptions the average head circumference was bigger in males than in females, but rarely at statistically significant levels. After the age of six months the mean head circumference of the Gilbertese fell almost invariably below the third percentile of a North American standard. The rate of growth of the skull in Gilbertese was also smaller than in North Americans, both absolutely and relative to the head circumference at birth. The possible role of early protein-energy malnutrition remained obscure.
对来自贝蒂奥的吉尔伯特群岛居民从出生到成年期间颅骨的生长情况进行了研究。除少数例外情况外，男性的平均头围比女性大，但很少达到统计学显著水平。六个月大之后，吉尔伯特群岛居民的平均头围几乎总是低于北美标准的第三百分位数。吉尔伯特群岛居民颅骨的生长速度，无论是绝对速度还是相对于出生时的头围而言，也都比北美居民小。早期蛋白质 - 能量营养不良可能起到的作用仍不明确。
