“…The specimens were stored on ice until they were transported to the laboratory twice weekly. They were analyzed using the Kato Thick Smear Method (Martin & Beaver, 1968) to determine the presence and intensity of Ascaris lumbricoides and Trichuris trichiura infections.…”

Objective: To determine whether nutritional status, anaemia and geohelminth infections were related to school achievement and attendance in Jamaican children. Design: A cross-sectional study using a randomly selected sample. Subjects: Eight hundred children aged 9±13 y randomly selected from those enrolled in grade 5 in 16 primary schools in rural Jamaica. Results: The mean height-for-age of the children was 70.37 z-score AE 1.0 s.d. with 4.9% having heights-for-agè 72 s.d. of the NCHS references. Anaemia (Hb`11 g/dl) was present in 14.7% of the children, 38.3% were infected with Trichuris trichiura and 19.4% with Ascaris lumbricoides. Achievement levels on the Wide Range Achievement Test were low, with children performing at grade 3 level. In multilevel analyses, controlling for socioeconomic status, children with Trichuris infections had lower achievement levels than uninfected children in spelling, reading and arithmetic (P`0.05). Children with Ascaris infections had lower scores in spelling and reading (P`0.05) Height-for-age (P`0.01) was positively associated with performance in arithmetic. Ascaris infection (P`0.001) and anaemia (P`0.01) predicted poorer school attendance. Conclusion: Despite mild levels, undernutrition and geohelminth infections were associated with achievement, suggesting that efforts to increase school achievement levels in developing countries should include strategies to improve the health and nutritional status of children Sponsorship: Funding was provided by the Commonwealth Caribbean Medical Research Council and the InterAmerican Development Bank.

“…Parasitological and specific immunodiagnostic assessment -Stool examination was performed by a formol-ether assay (Martin & Beaver 1968) and quantified by the Kato-Katz technique (Katz et al 1972). From each subject, two fecal samples were collected on different days before, and two after, treatment.…”

“…Although the Kato-Katz method is widely used for the diagnosis of intestinal helminths infections, its reported effectiveness varies. Garcia et al 2 observed that the Kato-Katz method was more sensitive than the thick smear technique for diagnosing helminths 2 , while Martin & Beaver 5 concluded that the Kato thick-smear technique is reliable and practical for the quantitative diagnosis of hookworm, Trichuris Trichiura and Schistosome infections 5 . On the other hand, Engels et al 1 showed that the Kato-Katz method is not suitable for hookworm, protozoa and filariform larvae detection 1 ; while another study concluded that the Kato method has a low sensitivity for identifying hookworm eggs, and observed that hookworm eggs collapsed and disappeared shortly after the thick smear had cleared 9 .…”
