Disabilities and health of extremely low-birthweight teenagers: a population-based study

Poorer outcomes of all low birth weight groups at age 10: Missouri statewide case-control study

BACKGROUND

In 1989-1991, a population-based cohort of every Missouri birth weighing < 1500 g was identified over a 16-month period. Infants born moderately low birth weight (MLBW, 1500-2499 g) and normal birth weight (NBW, ≥ 2500 g), were matched to < 1500 g infants by delivery date, race, maternal age, and residence.

AIMS

To compare outcomes of extremely low birth weight (ELBW, < 1000 g), very low birth weight (VLBW, 1000-1499 g), and MLBW, to NBW infants at age 10.

STUDY DESIGN

A population-based cohort and matched case-control study OUTCOME MEASURES: A Child Health and Development Questionnaire developed for this study collected social, medical, educational and special services history. The Conners' Parent Rating Scale-Revised was also completed by parents/caregivers.

RESULTS

As birth weight declined, the prevalence of adverse outcomes increased. Children in all LBW groups were more likely than NBW children to have problems in speech and language, vision, fine and gross motor tasks, illnesses, attention, school performance, and increased requirements for therapy and accommodation. Repetition of a grade was three times higher for MLBW children and over three times higher for the other LBW groups.

CONCLUSION

In this statewide population-based study, controlling for child's sex, mother's age, race, residence, education, marital status, Medicaid assistance, and smoking or alcohol use during pregnancy, failed to eliminate the strong effect of decreasing birth weight. Problems were most frequent in ELBW, however, VLBW and MLBW also had many significantly greater problems than NBW children. All LBW groups of children experienced greater adverse health and developmental outcomes resulting in significant habilitation and educational challenges.

Interpretation of ambiguities by schoolchildren with low birth weight from Embu das Artes, São Paulo state, Brazil

PURPOSE

To assess the development of language regarding the ability to recognize and interpret lexical ambiguity in low-birth-weight schoolchildren enrolled at the school system in the municipality of Embu das Artes, Sao Paulo state, compared with that of schoolchildren with normal birth weight.

METHODS

A case-control, retrospective, cross-sectional study conducted with 378 schoolchildren, both genders, aged 5 to 9.9 years, from the municipal schools of Embu das Artes. Study Group (SG) comprising 210 schoolchildren with birth weight < 2500 g. Control Group (CG) composed of 168 school children with birth weight ≥ 2500 g. Participants of both groups were compared with respect to the skills of recognition and verbal interpretation of sentences containing lexical ambiguity using the Test of Language Competence. Variables of interest: Age and gender of children; age and schooling of mothers. Statistical analysis: Descriptive analysis to characterize the sample and score per group; Student's t test for comparison between the total scores of each skill/subtest; Chi-square test to compare items within each subtest; multiple regression analysis for the intervening variables.

RESULTS

Participants of the SG presented lower scores for ambiguous sentences compared with those of participants of the CG. Multiple regression analysis showed that child's current age was a predictor for all metalinguistic skills regarding interpretation of ambiguities in both groups.

CONCLUSION

Participants of the SG presented lower specific and total scores than those of participants of the CG for ambiguity skills. The child's current age factor positively influenced the ambiguity skills in both groups.

School children with low birth weight inserted in system of Embu's education: construction of sentences

PURPOSE

To characterize the construction of sentences in schoolchildren born with low weight.

METHODS

We selected 413 students from Embu das Artes (SP), Brazil. Application of Recreating Speech Acts of Test of Language Competence sub-test. We analyzed the number of words and the holistic score. Age group of 6-10 years old, female/male, with low birth weight (<2,500 g) in Study Group (SG; n=238), and birth weight above or equal to 2,500 g composing the Control Group (CG; n=175). Children with anomalies were excluded. The both groups' responses were considered as well as the association of the responses with variables birth weight, gender, age of child and maternal age and education, through Student's t-test, χ2test and linear regression.

RESULTS

The SG scored less on the total number of words and had worst performance in items that involved prepositions with a sense of temporality and place, with adverb functions. There was no difference between groups regarding the holistic score. It was found positive impact of the variables birth weight (p=0.002), age of child, age of mother and maternal education on standard test scores in both groups.

CONCLUSION

The SG had fewer words compared to CG. The higher the birth weight, the higher the score test pattern. It was evident the age-related changes in morpho-syntactic skills addressed in the study, and protection factors mother's schooling and age had a positive impact on language performance.

Behavior and well-being of extremely low birth weight teenagers in Iceland

BACKGROUND

Preterm children are at risk for behavioral and emotional problems.

AIMS

To evaluate behavior and emotional well-being of extremely low birth weight (ELBW) teenagers born in Iceland in 1991-1995.

METHODS

Participants, 30 of 35 ELBW survivors (25 girls, 5 boys, mean age 16.8 years), were interviewed, underwent medical examination and answered the Youth Self-Report for ages 11-18 (YSR) of the Achenbach System of Empirically Based Assessment (ASEBA). The ELBW parents answered the ASEBA Child Behavior Checklist for ages 6-18 and the Autism Spectrum Screening Questionnaire (ASSQ). A comparison group of 30 teenagers (23 girls, 7 boys, mean age 16.5 years) answered the YSR questionnaire and their parents answered the CBCL and ASSQ questionnaires.

RESULTS

ELBW teenagers and parents report more behavior problems than the full term comparison teenagers and parents. They score significantly higher on the YSR and CBCL syndrome scales except for YSR and CBCL rule-breaking behavior and CBCL thought problems. The ELBW teenagers self-report on total competence, activities, social participation and academic performance was not significantly lower than the comparison teenagers. Parents of ELBW teenagers rated total competence, social participation and school performance of their children significantly lower than parents of comparison teenagers. The YSR Positive Qualities Scale was not significantly different between the two teenage groups. Two ELBW teenagers scored above cut-off points on the ASSQ questionnaire and none of the comparison teenagers. Bullying was reported by 20% of ELBW parents compared to none of the comparison group.

CONCLUSION

ELBW teenagers experience emotional, behavior and social challenges. The teenagers value their positive qualities, activities and academic performance similar to peers.

Quality of life of adolescents born with extremely low birth weight

AIM

To explore extremely low birth weight [ELBW] adolescents' self-reported quality of life [QoL] and compare it with control group of same age full-term peers.

METHODS

This project is nested within a national follow-up study on the long-term outcome of ELBW infants born in Iceland in 1991-1995. Twenty-nine ELBW adolescents and 30 controls evaluated their QoL using KIDSCREEN-52. To evaluate group differences, Chi-square tests and Mann-Whitney U-tests were conducted. Multivariate logistic regression was used to determine the influence of birth weight on QoL in ten dimensions.

RESULTS

No differences were observed between the groups on six of ten KIDSCREEN dimensions. ELBW adolescents reported significantly lower QoL on four dimensions: Physical well-being (OR 3.41; CI, 1.14-10.25), Psychological well-being (OR 7.65; CI, 2.04-28.78), Moods and emotion (OR 5.20; CI, 1.53-17.82), and Self-perception (OR 3.20; CI, 1.05-9.74).

CONCLUSION

ELBW adolescents report similar social well-being and participation compared with same age full-term peers. Conversely, they report lower physical and emotional quality of life.
