Health status development in a cohort of preterm children.

OBJECTIVE: To determine the impact of preterm birth on health status (HS) development at the ages of 5 and 10 years in a cohort of children born before term. SAMPLE: Six hundred eighty-eight children, born in 1983 with a gestational age of <32 weeks and a birth weight of <1500 g. DESIGN: Prospectively collected HS variables, obtained from the parents, were analyzed in a longitudinal perspective by using principal component analyses. RESULTS: One third of the sample had minor to severe HS problems at both ages of measurement. One third had problems on one assessment only. The remainder of the sample had no HS problems at either age. The analyses grouped the HS variables into 3 combinations. Problems in basic functioning, such as mobility or speech, decreased with age. Negative moods substantially increased, and concentration problems increased slightly. Specifically at risk were preterm born children with handicaps, boys, and children who were small for gestational age. CONCLUSION: According to the parents, one third of the cohort had no HS problems at either age. The pattern of HS problems of the preterm born children changed between 5 and 10 years of age.

School absence and treatment in school children with respiratory symptoms in The Netherlands: data from the Child Health Monitoring System.

STUDY OBJECTIVE: To assess the prevalence of respiratory problems, and the relation of these problems with school attendance, medicine use, and medical treatment. DESIGN: The Child Health Monitoring System. SETTING: Nineteen public health services across the Netherlands. PARTICIPANTS: 5186 school children aged 4-15 years, who were eligible for a routine health assessment in the 1991/1992 school year. MAIN RESULTS: Respiratory symptoms were present in 12% of the children. Recent symptoms suggestive of asthma (wheezing or episodes of shortness of breath with wheezing in the past 12 months, or chronic cough, or a combination of these) were reported for 8%. These symptoms were most frequent in the younger children, and in children at school in towns with less than 20,000 inhabitants. Of the children with recent symptoms suggestive of asthma, 37% reported school absence for at least one week during the past 12 months, compared with 16% in children without respiratory symptoms. School absence because of respiratory illness was reported for 22%, and medicine use for respiratory problems for 38% of the children with recent symptoms suggestive of asthma. Of these children, 21% were receiving medical treatment, compared with 15% of the asymptomatic children. CONCLUSIONS: Respiratory symptoms are a common health problem in children, and they are an important cause of school absence and medicine use. However, the percentage of children receiving medical treatment seemed quite low, indicating that proper diagnosis and treatment are probably still a problem.

School performance at nine years of age in very premature and very low birth weight infants: perinatal risk factors and predictors at five years of age. Collaborative Project on Preterm and Small for Gestational Age (POPS) Infants in The Netherlands.

To assess the impact of both perinatal disorders and developmental problems identified at preschool age on school performance, we followed a virtually complete birth cohort of very premature (< 32 completed weeks of gestation) and very low birth weight infants until they were 9 years of age. In 84% of the survivors (n = 813), data on school performance were available for analysis. At the age of 9 years, 19% of the children were in special education. Of the children in mainstream education, 32% were in a grade below the appropriate level for age and 38% had special assistance. After correction for other perinatal items, children of low socioeconomic status and boys had significantly higher adjusted odds ratios for special education. Logistic regression with a perinatal and a 5-year time category showed that the most predictive factors for special education were developmental delay, neuromotor and speech/language function, inattention and hyperactivity score, total problem score, and reported school results at the age of 5 years. When children with disabilities were left out of the analysis, the importance of neuromotor function and total problem score disappeared. Increased risks of any school failure in nondisabled children included mild or severe developmental delay and marginal or poor school performance at the age of 5 years. Long-term follow-up with specific attention to these predictors at 5 years of age, although time-consuming, is necessary.

Social class, ethnicity and other risk factors for small for gestational age and preterm delivery in The Netherlands.

Social class and ethnicity are important risk factors for small-for-gestational-age and preterm delivery in many countries. This study was performed to assess whether this is also the case in the Netherlands, a country with a high level of social security, relatively small income differences and easy access to medical care for all its inhabitants. Other risk factors that were taken into account were smoking, drinking, occupation, age and height. Information was collected by interview in the first 3 weeks of life of the mothers of 2027 (response 97%) live-born singletons born in the period from April 1988 to October 1989 in the study area. After adjustment for possible confounding factors very low social class, compared with high social class, was significantly associated with reduced birthweight (-4.0%; 95% CI, -7.4% to -0.7%), but not with preterm delivery (OR, 2.09; 95% CI, 0.67-6.48). The adjusted birthweight of Turkish infants (2.7%; 95% CI, -1.1% to 6.5%) and the adjusted birthweight of infants from Suriname or the Antilles (-1.6%; 95% CI, -5.5% to 2.1%) were not significantly different compared with infants of Dutch mothers. After adjustment, the frequency of preterm birth was lower in Turkish infants, but not significantly (OR, 0.22; 95% CI, 0.04-1.10), whereas the frequency of preterm birth in infants from Suriname or the Antilles was significantly higher (OR, 2.51; 95% CI, 1.04-6.08) compared with Dutch infants. Of the other factors the main risk factors were smoking (negatively related with birth-weight) and maternal age(ABSTRACT TRUNCATED AT 250 WORDS)

Is it correct to correct? Developmental milestones in 555 "normal" preterm infants compared with term infants.

To determine whether correction for preterm birth should be applied during developmental assessment, we conducted a prospective national survey of very premature infants (born at less than 32 weeks of gestation); neurodevelopment in the first 2 years was studied with the Dutch child health care developmental assessment. In 555 preterm children who had no evidence of handicap at 2 years of age, the age at which developmental milestones were reached was established. The results were compared with the results of the same assessment in Dutch children born at term. During the first year, the development of the very premature children equaled the development of normal children when full correction was applied. At 2 years of age, development was equal to or better than normal children's development without correction. We conclude that full correction for prematurity should be applied in the first year to avoid overreferral for developmental stimulation, whereas at 2 years of age correction is not necessary.
