Behavioural and cognitive associations of XXXX at 5 years.

@entity1 @entity2673 @entity851 @entity102
OBJECTIVES: To determine the extent to which childhood @entity851 is associated with cognitive, behavioural and chronic health problems, and whether these problems could be attributed to recognized adverse biological, psychosocial or psychological factors. METHODOLOGY: At their first antenatal session, 8556 @entity1 were enrolled in a prospective study of pregnancy. When their @entity1 were 4 and 6 years of age, mothers completed a detailed questionnaire concerning their @entity1 's health and behaviour. A Peabody Picture Vocabulary Test-Revised (PPVT-R) was completed by the @entity1 at 5 years of age. Z scores were used to categorize height measurements in 3986 @entity1 . The relationship of these height categories with the @entity1 's health, and behavioural and cognitive problems was then examined. RESULTS: No association was found between height and symptoms of @entity102 or behaviour problems in @entity1 or @entity1 . On the unadjusted analysis, mean PPVT-R scores were significantly lower in @entity1 with heights < 3 percentile and 3-< 10 percentile compared with study @entity1 between 10 to 90 percentile (P < 0.01). Scores were similarly significantly lower in @entity1 with heights < 3 percentile and 3-10 percentile (P = 0.01). Even after adjusting for psychosocial and biological confounders, @entity851 remained a significant predictor for lower PPVT-R scores in both @entity1 and @entity1 , although height only accounted for 1.1% of the variance in scores in @entity1 and 0.5% of the variance in PPVT-R scores in @entity1 . Psychosocial factors had a greater role than height in determining PPVT-R scores at 5 years of age. CONCLUSIONS: These findings suggest a significant, though small, association between height and PPVT-R scores at 5 years of age, independent of @entity2673 and known biological risk factors.
