Prevalence of safe turmeric consumption was significantly higher in the intervention versus control arm at endline (adjusted risk difference: 0.22 [0.10 to 0.32]).
Contexto
What changed: Community health workers delivered group sessions on lead toxicity and demonstrated how to avoid adulterated turmeric and lead-soldered storage cans. Comparison: Control villages receiving standard early childhood development and WASH sessions without the lead module. Limits: Behaviors were largely self-reported and biological markers such as blood lead levels were not measured.
