Results were aggregated across all four surveys i.e. ‘never’ = responded with ‘never’ in all surveys the household participated; ‘at times’ = household reported the behaviour as ‘sometimes’ in at least one survey round or had conflicting statements; ‘always’ = responded with ‘always’ in all surveys the household participated. Exposure and attitude were similarly aggregated, i.e., ‘once’ = reported exposure or positive attitude score at one of the four survey rounds; ‘twice or more’ = at two or more survey rounds
