Filter by:Autism and associated entities, grouped under the Autism Spectrum Disorders (ASD) is the fastest growing intellectual disability in the world, statistics signal for a 1 to 3% prevalence on infants. The cause is unknown, although some data suggest that zinc deficiency during pregnancy may have an important role in its presentation. This study seeks to supplement the nutrition of randomly selected prospective and actually pregnant women with a zinc-Amino-acid complex (Zn-AA), during pregnancy and early lactation, and compare the rate of ASD in their offspring with the rate in a similar and also randomly selected cohort of non supplemented women, to assess if Zn-AA supplementation during pregnancy has any effect on this outcome
The overall aim of this trial is to determine whether the use of the household-based water treatment device Life Straw Family (LSF) can be an effective strategy to improve zinc status and health status of vulnerable populations in developing country rural settings with poor access to potable water. To assess the effectiveness of the LSF strategy (a filter delivering purified and zinc enriched water) a double blind controlled field efficacy trial will take place over a period of 12 months in rural villages in the district of Natitingou, North-West Benin. In order to attain the research objectives the efficacy trial will envisage 3 arms: intervention (zinc enriching filter), placebo (filter) and control group (disinfection tables). During the trial the following outcomes will be monitored: zinc status and growth rate of the participating children, zinc status and pregnancy outcome in a sub-sample of pregnant women (pregnancy sub-study), diarrhea prevalence in all participating subjects, water quality, zinc enrichment of water, and modality and consistency of use of the LSF-device by the study population. The study hypotheses are: 1) the use of the LSF-device will reduce microbiological contamination of the household water, 2) the use of the LSF-device will increase zinc intakes and serum zinc concentration in preschool children, 3) the use of the LSF-device will increase zinc intakes and serum zinc concentration in pregnant women, 4) the achievement of 1 and 2 will improve growth and lower frequency and length of diarrhea episodes in participating preschool children, 5) the achievement of 1 and 3 will improve pregnancy outcome and lower frequency and length of diarrhea episodes in participating pregnant women, 6) the use of the LSF-device will lower frequency and length of diarrhea episodes in participating households members.
