ObjectiveThe study was conducted to assess the effectiveness of six monthly albendazole (ABZ) for improving the weight and height of preschool children when initiated at 0.5-1 year of age in populations with a high transmission rate of intestinal roundworm, Ascaris lumbricoides. It was a cluster randomized trial in the urban slums of Lucknow, North India.MethodsControl children received 2 ml (1 ml to infants) of Vitamin A every six month whereas those in the ABZ areas received, in addition, 400 mg of ABZ suspension (Zentel, SKB) every six month. Sixty-three and sixty-one slum areas were randomized to albendazole (ABZ) or to control groups, respectively. Children aged 0.5-1 year were recruited in April 1996 and followed up for 1.5 years. Of 1022 children recruited from control and 988 from ABZ areas, the loss to follow-up at 1.5 year was 15.6% and 14.6% respectively. Mean (+/- SE) weight gain in Kg in control versus ABZ areas was 3.04 (0.03) versus 3.22 (0.03), (p = 0.01).ResultsAfter controlling for the presence of weight-for age z-score < -2.00 at enrollment in the ordinary least square's regression model, the extra weight gain in 1.5 years in those who received ABZ plus vitamin A was 0.13 Kg (95% CI: 0.004 to 0.26 Kg., p value = 0.043) when compared to those who received only vitamin A; underweight children at enrollment benefiting more than the normal ones.ConclusionIt was concluded that there was an improvement in weight with six monthly ABZ over 1.5 years. However, a much larger trial would be needed to determine whether there is any net effect of improvement in weight on under five mortality rate.
