Are fetal growth impairment and preterm birth causally related to child attention problems and ADHD?:Evidence from a comparison between high-income and middle-income cohorts
No full textBACKGROUND: Cross-cohort comparison is an established method for improving causal inference. This study compared 2 cohorts, 1 from a high-income country and another from a middle-income country, to (1) establish whether birth exposures may play a causal role in the development of childhood attention problems; and (2) identify whether confounding structures play a different role in parent-reported attention difficulties compared with attention deficit hyperactivity disorder (ADHD) diagnoses.METHODS: Birth exposures included low birth weight (LBW), small-for-gestational age (SGA), small head circumference (HC) and preterm birth (PTB)). Outcomes of interest were attention difficulties (Strengths and Difficulties Questionnaire, SDQ) and ADHD (Development and Well-Being Assessment, DAWBA). Associations between exposures and outcomes were compared between 7-year-old children from the Avon Longitudinal Study of Parents and Children (ALSPAC) in the UK (N=6849) and the 2004 Pelotas cohort in Brazil (N=3509).RESULTS: For attention difficulties (SDQ), the pattern of association with birth exposures was similar between cohorts: following adjustment, attention difficulties were associated with SGA (OR=1.59, 95% CI 1.20 to 2.19) and small HC (OR=1.64, 95% CI 1.11 to 2.41) in ALSPAC and SGA (OR=1.35, 95% CI 1.04 to 1.75) in Pelotas. For ADHD, however, the pattern of association following adjustment differed markedly between cohorts. In ALSPAC, ADHD was associated with LBW (OR=2.29, 95% CI 1.09 to 4.80) and PTB (OR=2.33, 95% CI 1.23 to 4.42). In the Pelotas cohort, however, ADHD was associated with SGA (OR=1.69, 95% CI 1.02 to 2.82).CONCLUSIONS: The findings suggest that fetal growth impairment may play a causal role in the development of attention difficulties in childhood, as similar associations were identified across both cohorts. Confounding structures, however, appear to play a greater role in determining whether a child meets the full diagnostic criteria for ADHD.</p

Birth Weight And Hospital Mortality Among The Newborns In Maternity, 1975-1996 [peso Ao Nascer E Mortalidade Hospitalar Entre Nascidos Vivos, 1975-1996]
No full textObjective To assess the trend of birth weight and hospital mortality rate of newborns, in a maternity hospital of Campinas, SP. Methods A total of 215,435 births of a maternity hospital in Campinas, S. Paulo State, Brazil, was studied between 1976 and 1996. Information was collected from registration files and annual reports of medical care. All the newborns from that period were included. The causes of death that occurred before the discharge, regardless the age, were analyzed. For data analysis, Epi info 6.01 method was used. Results Birth weight distribution remained the same for the 22 years period studied. Low birth weight was seen in about 9% of newborns, and accounted for 82% of hospital deaths in 1996. Below average weight was observed in about 24% of the newborns. We could notice an improvement in survival for those who had a birth weight between 1,000 g and 1,999 g. In 1975, 13.3% of those with weights between 1,000 g and 1,499 g survived and 73.8% of those who weighed between 1,500 g and 1,999 g. In 1996, survival rates increased to 69.1 % and 87.7% respectively. Hospital mortality rate among infants whose weight was below 1,000 g remained high, between 78.9% and 100%, even in the 90's. There was a reduction of hospital mortality rates from 17 to 11 per thousand live births. Conclusions There was not any change in the distribution of birth weight despite improvements in life conditions of Campinas population. The decrease in mortality rates is due to improvement in health care which is very expensive. There is a need of other studies to allow why birth weight distribution remained the same.3417176Barros, F.C., Vaughan, J.P., Victora, C.G., Huttly, S.R.A., Epidemic of cesarean sections in Brazil (1991) Lancet, 339, pp. 167-169Caiado, A.S.C., Metrópoles, cidades médias e pequenos municípios paulistas: Estudo comparado da qualidade de vida e dinâmica socioespacial (1997) Migração, Condições de Vida e Dinâmica Urbana: São Paulo, 1980-1993, pp. 115-152. , Patarra NL et al., organizadores.
