Summary

The study evaluates the impact of a personal and domestic hygiene intervention on exposure to lead in a community close to a mine dump. A before and after intervention study will be conducted in a selected area to determine lead exposure levels and the reduction or not after application of the intervention.

Detailed description

A before and after intervention study will be conducted with a control and intervention group, where data will be collected at the household (through questionnaire based interviews, floor and/or windowsill samples and soil samples collection) and individual level (through hand dust wipe sample collection). In phase one, both the control and intervention group will be interviewed, household floor and/or windowsill dust wipes will be taken, yard soil sample collected and hand dust wipe samples will be taken from children in participating households. After baseline data collection, participants will be allocated into either intervention or control group. The intervention group will participate in the domestic hygiene demonstration and educational discussion.

Interventions

Type	Name	Description
BEHAVIORAL	Domestic Hygiene and household hygiene Intervention	A demonstration on the domestic hygiene intervention will be conducted where participants will be guided on optimal cleaning of windowsills, floors and other surfaces with water and detergent, and advised on appropriate method of cleaning. Participants will be provided with a package of cleaning materials (mop, bucket, detergent, hand wash liquid soap and cloth for wet dusting) which will be used during the demonstration, and retained by participants to facilitate sustainability of the intervention during and after the study. Participants will be further engaged in an educational discussion, with the aid of a specially designed educational pamphlet containing information about health effects potentially associated with dust lead exposure from mine dumps and the personal hygiene and domestic hygiene steps that may be followed to reduce dust lead exposure.
