OBJECTIVES: To determine why, in the London Borough of Hackney before 1990, fewer children than expected were identified with remedial causes of short stature. To construct a practical model for height surveillance of 5 and 11 year old school entrants to improve the quality of child growth surveillance. SETTING: City and Hackney Borough, London, United Kingdom. METHODS: School nurses were trained by a clinical auxologist to measure children's height at school entry accurately and reproducibly. New procedures for measurement technique, plotting of data, referral, and audit were established. A reference manual was provided and a continuing training programme was started. RESULTS: During the first year the percentage of the target group measured was low. Changes in work practice led to improvements from 77% measured in the first year to 91% in the second year and 87% in the third year for 5 year olds. Improvements for 11 year olds were from 36% to 86% to 87% over the three years. Only 1.2% of 5 year olds and 2.6% of 11 year olds measured had height less than the third centile (compared with Tanner's height standards). CONCLUSIONS: School nurses measured height reliably. New audit procedures led to rapid changes in working practice and improvements in the percentage of children measured. The low numbers of short children previously identified with unrecognised abnormality may indicate an upward trend in height in this inner city population.
The authors aim at finding the connection between the intrauterine ponderal index (IUPol) and the neonatal ponderal index (NPol) and to estimate the efficiency of IUPol in the prediction of the asymmetric growth retardation in the new born babies with NPol below 2SD for the corresponding gestational age. 142 patients were examined. The foetus weight was calculated by the formula: EFBW = 1,4 x BPD x FL - 200, and the foetus length was calculated by the formula: 6,18 x 5,9 x FL. The authors concluded that the good sensitivity and specificity of the application of IUPol in the diagnostics of the asymmetric growth retardation need wider use of this method and the IUPol can be used for the elimination of the fetal retardation, because of the high predictable level of the negative test.
OBJECTIVE: To establish whether poor height or height velocity, assessed during the year of school entry, might identify children with previously undiagnosed organic disease. DESIGN: Observation of a total population and their case controls. SETTING: Community base. SUBJECTS: All 14,346 children in two health districts entering school during two consecutive years were screened for height by school nurses, and those whose height lay below the 3rd centile according to Tanner and Whitehouse standards (n = 180) were identified. After excluding 32 with known organic disease, five from ethnic minorities, and three who refused to take part, the remaining 140 short normal children were matched with 140 age and sex matched controls of average height (10th-90th centile) and their height velocities over 12 months measured. MAIN OUTCOME MEASURES: Height, height velocity, previously diagnosed organic disease, and organic disease diagnosed as a result of blood tests and specialist examination. RESULTS: Twenty five of the 180 short children (14%) were already known to have chronic organic disease which could explain their poor growth. Blood tests and specialist examination revealed a further seven with organic disease, which was acquired rather than congenital in three, and a second cause of short stature in one with known organic disease. These eight conditions had been missed at the school entry medical examination. The shorter the child, the more likely an underlying organic disorder, with seven of the 12 children whose heights were more than 3 standard deviations below the mean having some organic disease. Height velocity measured over 12 months, however, did not distinguish short normal children from those with disease or from their matched controls. CONCLUSIONS: Height, but not height velocity, is a useful index for identifying unrecognised organic disease at school entry. The shorter the stature the greater the prevalence of organic disease. The frequency of newly diagnosed remediable disease in this study (1 in 3-4000) is similar to that of neonatal hypothyroidism, which is routinely screened for. Routine investigation of all very short school entrants is recommended.
