We analyzed the characteristics associated with the growth in height of Japanese triplets from birth to 12 years of age. The study included 376 mothers and their 1,128 triplet children, who were born between 1978 and 2006. Data were collected through a mailed questionnaire sent to the mothers asking for information recorded in medical records. For these births, data on triplets' length and height growth, gestational age, sex, parity, maternal age at delivery, and maternal height were obtained from records in the Maternal and Child Health Handbooks and records in the school which children receive health check-ups. The height deficit of the triplets compared to the general population of Japan remained between 2% and 5% until 12 years of age. Moreover, at 12 years of age, the differences of height between the general population and triplets were approximately -3.6 cm for male and -4.4 cm for female. Maternal height showed the strongest contribution to height of triplets from 6 to 12 years of age. In conclusion, triplets remain shorter than singletons until 12 years of age.
