The prevalence, stability and significance of developmental language delays in preschool children | 1980
Silva, P.A.
Developmental Medicine and Child Neurology, 1980, 22(22), 768-777.
Our ref: RO7
Show abstract » A sample of 937 children in Dunedin, New Zealand, was assessed at ages three and five years in order to estimate the nature, prevalence, stability and significance of developmental language delays in three-year-olds. Assessments included language development, intelligence, and fine and gross motor-co-ordination. Detailed results are given which described three types of language delay at age three: delayed verbal comprehension only, delayed verbal expression only, and delayed development in both aspects of language. Follow-up testing at age five indicated that the specific language delays were not highly stable, whereas delays in both aspects were highly stable. A large proportion of the latter children gained very low scores on the measures at age five, and they accounted for 84 per cent of all children with very low intelligence. The implications of the results for a screening programme to identify three-year-old children at high risk of later developmental delays are considered.

Show abstract » A study of 1037 representative Dunedin children delivered by a variety of modes was described. The results showed that there were no significant differences in maternal general mental ability, training in child development, or background of child experiences among the five delivery groups studied. Also, there were no significant differences between children who were spontaneous deliveries or any of the other groups in age at which the developmental milestones were achieved, nor in any of the developmental characteristics assessed.

Show abstract » Poisoning, burns, and other accidents experienced by 1037 Dunedin children during their first three years of life are described. 7.8% of the children ingested poison, 4.9% were burned, and 21.4% experienced other accidents for which medical advice was sought. The children who had been poisoned were of significantly lower intelligence than the remainder although those who had had other accidents did not differ significantly in this respect. The mothers of children poisoned or who had had accidents were not significantly different from the remainder in terms of general mental ability or training in child development.

Breast-feeding and some reasons for electing to wean the infant: A report from The Dunedin Multidisciplinary Child Development Study | 1978

New Zealand Medical Journal, 1978, 88(88), 273-276.
Our ref: NZ4
Show abstract » Data are presented on the prevalence of breast feeding among 1037 Dunedin mothers who gave birth to infants between April 1972 and March 1973 and their reasons for weaning. Although breast feeding was becoming more common at that time, more than two-thirds of the mothers weaned their babies as a result of the difficulties they encountered. One of the most significant factors in lactation failure is the mismanagement of breast feeding by health professionals.

New Zealand Medical Journal, 1976, 11(11), 74-77.
Our ref: NZ2
Show abstract » An experimental group of 142 children aged four years who had experienced neonatal at risk factors and a control group of 112 children whose perinatal histories were optimal had vision screening tests to detect defective vision or strabismus. Five (3.5 percent) in the at risk group and 10 (8.9 percent) in the control group (total 15, 5.9 percent) were found to have a visual defect. Of those, six had already been identified because of a manifest squint. Nine children with defective vision were first identified through the study. The importance of the early identification and treatment of visual disorders, particularly amblyopia, is emphasised, and recommendations are made for more widespread vision screening of preschool children.

New Zealand Medical Journal, 1975, 81(81), 279-282.
Our ref: NZ1
Show abstract » The four-year-old growth status of 56 preterm, 35 small for gestational age, and 111 randomly selected appropriate weight for gestational age children who were born at the Queen Mary Hospital (Dunedin) in 1968, is described. Children who were preterm but were greater than 2500g at birth were significantly heavier, taller and had larger head circumference measures than the control group. Preterm children who had weighed less than 2500g at birth were significantly lighter than the controls. Children who were smaller for gestational age were significantly shorter and lighter than the control group. Other results were reported on relationships between gestational age and birth weight and the later growth status of children, and some implications were discussed.

Show abstract » Aims: To investigate the occurrence, associations, and impacts of self-reported nocturnal parafunction, daytime parafunction, temporomandibular joint (TMJ) pain, and TMJ clicking in a New Zealand birth cohort of 38-year-old individuals. Methods: A cross-sectional analysis of data from a longstanding prospective observational study of a Dunedin, New Zealand birth cohort was undertaken. A questionnaire was used to measure self-reported nocturnal parafunction, daytime parafunction, TMJ pain, and TMJ clicking, and the short-form Oral Health Impact Profile (OHIP-14) tool was used to measure the impacts of these factors while controlling for personality traits. Results: Of the 912 participants (49.7% female) who were dentally assessed and had completed questionnaire data, 31.6% reported nocturnal parafunction and 48.3% reported daytime parafunction. TMJ pain was reported by 29.4% and TMJ clicking by 34.8%. The prevalence of daytime grinding was significantly greater among women (54.2%) than men (42.5%), as was the prevalence of TMJ pain (34.5% and 24.1%, respectively). Those with parafunction or TMJ symptoms had higher mean OHIP-14 scores, and this difference remained significant after controlling for sex, socioeconomic status, xerostomia, untreated dental caries, missing teeth, and personality traits. Conclusion: People with parafunction or TMJ symptoms have poorer oral health–related quality of life than those without these symptoms.
