Abstract
Children are frequently invited to exercise before micturition, as it is believed that this activity will result in higher egg excretion, and hence, increases sensitivity of microscopic diagnoses. However, the evidence of this recommendation is scant. In the study presented here, 257 children, aged 2-15 years from south Côte d'Ivoire, provided urine samples for microscopy on consecutive days; one sample without prior exercise and one sample after exercise. Comparing the same individuals without and with prior exercise, sample positivity for (25.7% versus 23.0%, = 0.31) and mean egg counts (10.2 eggs/10 mL versus 8.5 eggs/10 mL, = 0.45) did not differ. Exercise before urine collection does not appear to increase egg excretion.
