“…These trends were consistent with those reported by Buckler and Green (1994). However in the present study, the weight deficit of the triplets, which was more than 40% at birth, decreased within the first year but remained between 4% and 9% until 6 years of age.…”

“…Studies on the birthweight of twins or triplets have been conducted in many countries (Arbuckle et al, 1993;Buckler & Green 1994;Glinianaia et al, 2000;Kato, 2004;Min et al, 2000;Min et al, 2004). However, there are few previous studies on the physical growth of triplets after birth in the world, while a number of studies on the physical growth of twins after birth have been conducted (Akerman & Fischbein, 1992;Alfieri et al, 1987;Luke et al, 1995;Ooki & Yokoyama, 2004;Philip, 1981;Silventoinen et al, 2007a;Wilson, 1974;Wilson, 1976;Wilson, 1979).…”

W e analyzed the characteristics of weight growth and present the weight growth charts from birth to 6 years of age in Japanese triplets. The study included 366 mothers and their 1098 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' weight growth, gestational age, sex, parity, and maternal age at delivery were obtained from records in the Maternal and Child Health Handbooks, which is provided by the authorities after a report of pregnancy. Birthweight proved to be the strongest contribution on weight of triplets from 1 to 6 years of age. In addition, gestational age was also a significant contributing factor to weight from birth to 6 years of age. Moreover, males had a higher weight from birth to 6 years of age than females. Compared to the 50th percentile of the growth standard for the general population of Japan, the weight deficit of the triplets was more than 40% at birth (male, -1.28 kg; female, -1.28 kg), decreased within the first 1 year of age, and fluctuated between 4% and 9% until 6 years of age (male, -1.82 kg; female, -1.78 kg). In conclusion, triplets have lower birth weight than singletons and in spite of the rapid catch-up growth during first year of life they are behind singletons even in mid-childhood. This study provides growth curves for use in triplets.

“…Previous studies in twins have reported similar results at birth (Buckler & Green, 1994;Glinianaia et al, 2000) and from 3 to 12 years of age (Silventoinen et al, 2007). Moreover, Lamb et al (2011) reported that the thirdborn trizygotic triplets were lighter than the second-born or the firstborn trizygotic children.…”

“…In the meanwhile, a number of studies on the postnatal growth of twins have been conducted (Akerman & Fischbein, 1992;Alfieri et al, 1987;Luke et al, 1995;Buckler & Green, 2004;Ooki & Yokoyama, 2004;Silventoinen et al, 2007;Wilson, 1976;Wilson, 1979). The weight deficit of twins is greatest at birth but decreases dramatically during the first year of life because of rapid catch-up growth, reaching as little as approximately 2% for weight, by 4 years of age (Buckler & Green, 1994;Ooki & Yokoyama, 2004). However, there are few previous studies on the postnatal growth of triplets in the world.…”

We analyzed the characteristics associated with the growth in weight 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' weight growth, gestational age, sex, parity, maternal age at delivery, maternal height, and maternal body mass index were obtained from records in the Maternal and Child Health Handbooks and records in the school where children receive health check-ups. The weight deficit of the triplets compared to the general population of Japan remained between 10% and 17% until 12 years of age. Moreover, at 12 years of age, the differences of weight between the general population and triplets were approximately -4.75 kg for boys and -6.00 kg for girls. Very low birth weight had the strongest contribution to body weight until 8 years of age. After 8 years of age, maternal body mass index was a significant factor affecting the weight of triplets until 12 years of age.

Context It has been reported that childhood psychotic symptoms are common in the general population and may signal neurodevelopmental processes that lead to schizophrenia. However, it is not clear whether these symptoms are associated with the same extensive risk factors established for adult schizophrenia. Objective To examine the construct validity of children’s self-reported psychotic symptoms by testing whether these symptoms share the risk factors and clinical features of adult schizophrenia. Design Prospective, longitudinal cohort study of a nationally representative birth cohort in Great Britain. Participants A total of 2232 twelve-year-old children followed up since age 5 years (retention, 96%). Main Outcome Measure Children’s self-reported hallucinations and delusions. Results Children’s psychotic symptoms are familial and heritable and are associated with social risk factors (eg, urbanicity); cognitive impairments at age 5; home-rearing risk factors (eg, maternal expressed emotion); behavioral, emotional, and educational problems at age 5; and comorbid conditions, including self-harm. Conclusions The results provide a comprehensive picture of the construct validity of children’s self-reported psychotic symptoms. For researchers, the findings indicate that children who have psychotic symptoms can be recruited for neuroscience research to determine the pathogenesis of schizophrenia. For clinicians, the findings indicate that psychotic symptoms in childhood are often a marker of an impaired developmental process and should be actively assessed.
