There were 1954 boys and 1909 girls in the study. They were(More)
The associations between perinatal events and neonatal morbidity were examined in a regional population of 5 380 newborns weighing 500 g or more. Perinatal mortality was 6.9%, and neonatal mortality was 3.0%. The low birth weight (less than 2500 g) rate was 3.8%. The incidence of prematurity (gestational age less than 37 weeks) was 6.6%. Respiratory(More)
Neonatal mortality (NNM) was investigated in the region of the University Central Hospital of Turku (UCHT), Finland, during a 15-year period from 1968 till 1982. During the study period 81 620 liveborn infants were born. The NNM rate declined from 13.5 in 1968 to 3.0 in 1982 during the study period. Significant declines occurred in NNM due to respiratory(More)
The somatic growth of a regional birth cohort of 351 preterm infants was followed during their first two years. The measurements of weight, height, head and thorax circumferences took place at the well-baby clinics run by public health nurses at 3, 6, 12, 18 and 24 months of conceptional age. The growth of the preterm infants was compared with that of their(More)
In a representative study of 5356 five-year-old children, 4405 (82.2%) could be traced for follow-up. Headache occurred in 861 (19.5%) of them; highly frequently in 0.2%, fairly frequently in 0.5%, less frequently in 4.3% and infrequently in 14.5%. Type of dwelling was the only predictor of housing standard, the risk of headache being about 1.5-fold in(More)
At the age of two years developmental outcome of 519 small-for-gestational age (SGA) children and 3375 control children was studied in southwestern Finland. A modification of the Denver Developmental Screening Test was used for follow-up. A significantly higher number of developmental abnormalities was found in SGA children than in the control children at(More)
The physical growth of 519 small for gestational age infants (SGA), with a birth weight below the 10th percentile on our own growth curve, born in the region of University Central Hospital of Turku during the period June 1, 1981-May 31, 1982, was studied. The study population consists of 4,517 term, appropriate for gestational age (AGA) infants, 488 term(More)
Perinatal mortality (PNM) in the catchment area of the University Central Hospital of Turku (UCHT), Finland, was investigated during a 15-year period from 1968 to 1982. During the study period, 82,151 babies were born, there were 531 fetal deaths and 505 cases of early neonatal death. The PNM rate declined during the study period from 17.9 in 1968 to 7.0 in(More)
