A preliminary survey of XXXX and helminthiasis among schoolchildren in one mountain and one lowland ujamaa village in Northern Tanzania.

The nutritional status, parasite prevalence and immediate @entity272 to Ascaris and @entity4114 antigens were determined for 185 schoolchildren living in two ujamaa villages in Northern Tanzania. In the lowland village of Kwamsisi the parasite ova found were @entity4114 (53.8%), Ascaris (26.0%) and hookworm (24.7%). 57.5% of the @entity1 examined were regarded as malnourished, being less than 80% of their expected weight for age. In the mountain village of Ubiri the parasite prevalence rates were 15.2% for @entity4114 , 1.6% for @entity383 , 65.2% Ascaris and 24.1% hookworm. @entity3147 was found in 81.9% of the @entity1 and in 41.2% of the @entity1 . This sex difference is considered to be due to the physiological effects of living in a hilly environment. Correlation between @entity3147 and @entity281 of Ascaris, hookworm and @entity4114 gave a chi-square value of 5.972 (p = 0.02). All other statistical comparisons between parasite prevalence and nutritional status were insignificant. Immediate @entity272 tests proved unreliable with 23.3% false negatives (negative skin test with parasite ova found). The serum IgE levels were extremely high with a mean of 3174 units per ml suggesting that the immune mechanisms were not retarded by undernutrition.
