 A total of 240 CHWs, who work in the province, will be stratified in four groups according to gender and urbanrural setting. A stratified sample of 240 CHWs was randomly selected with proportional allocation to strata. Within strata, CHWs were randomly assigned 1:1 to study groups. All selected CHWs were informed about the study by the PHC heads. We will produce computer-generated random number lists for the CHW random selection and the intervention allocation. Blinding of intervention and outcome assessments was not feasible.
