Handwashing with soap is recognised as a cost-effective intervention to reduce morbidity and mortality associated with enteric and respiratory infections. This study analyses rural Indonesian households’ hygiene behaviours and attitudes to examine how motivations for handwashing, locations of handwashing space in the household, and handwashing moments are associated with handwashing with soap as potential determinants of the behaviour.
The analysis was conducted using results from a UNICEF cross-sectional study of 1,700 households in six districts across three provinces of Indonesia. A composite measure of handwashing with soap was developed that included self-reported handwashing, a handwashing demonstration, and observed handwashing materials and location of facilities in the home. Prevalence ratios were calculated to analyse associations between handwashing with soap and hypothesised determinants of the behaviour.
Results showed that determinants that had a significant association with handwashing with soap included: (1) a desire to smell nice; (2) interpersonal influences; (3) the presence of handwashing places within 10 paces of the kitchen and the toilet; and (4) key handwashing moments when hands felt dirty, including after eating and after cleaning child stools. This study concludes that handwashing with soap may be more effectively promoted through the use of non-health messages.
