RESUMEN
OBJECTIVE: To assess health status of 9-10-year old school children in Sri Lanka. DESIGN: A cross-sectional, descriptive study. Schools were selected to obtain a sample representative at national and provincial levels and 20 children were randomly selected from Grade 5 classes in each school. MEASUREMENTS: Children were examined for Bitot's spots and goitre. Height, weight, and visual acuity were measured according to standard procedures. Haemoglobin level was measured using finger-prick blood and a HemoCue meter. Geohelminth infections were quantified by faecal examination using the modified Kato-Katz technique. Height for age Z-scores (HAZ) and body mass index (BMI) were calculated as indicators of nutritional status. RESULTS: Two thousand five hundred and twenty eight children (1351 boys) from 144 schools (140 state schools and four private schools) were examined. Nationally, 15.5% of children were stunted (HAZ lower than -2.0 SD); 52.6% were thin (BMI < 5th centile of age- and sex-matched reference population); 3.1% were overweight (BMI > 85th centile); 12.1% were anaemic; 0.3% had Bitot's spots; 3% had a visible or palpable goitre; 4.6% were shortsighted; and 6.9% had one or more soil-transmitted nematode infection. Among children on whom anthropometry, haemoglobin and faecal examinations were all done, 64.6% (1332/2063) were thin, stunted, anaemic or infected with worms. A much higher proportion of children in the Northern and Eastern provinces had health problems when compared to the other provinces. CONCLUSIONS: The majority of older primary schoolchildren in Sri Lanka are undernourished. Anaemia, vitamin A deficiency, iodine deficiency and soil-transmitted nematode infections affect a much smaller proportion of them.

A worm was extracted from the subconjunctival space of the left eye in a 14-year old Sri Lankan girl, who returned to Sri Lanka in 1983 after spending six years in Nigeria. It was identified as a male Loa loa. A history of evanescent (Calabar) swellings was obtained. She also had significant eosinophilia. Microfilariae were not detected in the blood. This is the first case of Loa loa infection reported from Sri Lanka.
