RT Journal Article SR Electronic T1 Influence of illness on developmental progress in children under two JF The Journal of the Royal College of General Practitioners JO J R Coll Gen Pract FD British Journal of General Practice SP 273 OP 277 VO 28 IS 190 A1 Starte, G. D. YR 1978 UL http://bjgp.org/content/28/190/273.abstract AB Illnesses occurring in children under two were recorded in relation to a systematic programme of child surveillance in one general practice. The most important result of this study was that although illness does have a detectable effect on developmental progress, the degree of that influence is for the most part small. Illnesses experienced between 0 and 7 months have less influence upon seven-month developmental scores than upon 24-month developmental scores, but have a greater influence upon the latter than do illnesses experienced between 7 and 24 months. There was a significantly higher consultation rate for boys and for children from social classes 3b, 4, and 5.
