Handwashing with soap is recognized as a cost-effective intervention to reduce morbidity and mortality associated with enteric and respiratory infections. This study analyzes rural Indonesian households’ hygiene behaviors 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 behavior. The analysis was conducted using results from a UNICEF cross-sectional study of 1700 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 analyze associations between handwashing with soap and hypothesized determinants of the behavior. Our 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.

Women experience many motivational drivers for improving sanitation, but it is unclear how women's role in household decision making affects whether a household opts for better sanitation. We analyzed the Kenya Demographic and Health Survey 2008/2009 with a representative sample of 4,556 married and cohabiting women to examine the association between women's decision making power in relation to that of partners and the type of sanitation facilities used by household members. The independent effects of respondents’ education, employment status, and socioeconomic status on the type of sanitation facilities were also explored. The direct measurement of women's ability to influence sanitation practice was not available. To address this problem, this study used proxy measures of women's decision making power in the household. The results of this study revealed that women's decision making power for major household purchases was positively associated with households having better sanitation (p < 0.05). The findings suggest that increased gender equity could potentially have spillover effects that result in more households opting to improve their sanitation conditions.

BackgroundHigh-risk water, sanitation, and hygiene (WASH) practices are still prevalent in most low-income countries. Because of limited access to WASH, children may be put at an increased risk of diarrheal diseases.ObjectivesThis study aims to 1) develop a new measure of WASH-induced burden, the WASH Resource Index (WRI), and estimate its correlation with child diarrhea and an additive index of high-risk WASH practices; 2) explore the geographic distribution of high-risk WASH practices, child diarrhea, and summary indices at the cluster level; and 3) examine the association between the WRI and child diarrhea at the individual level.DesignA sample of 7,019 children from the Uganda Demographic and Health Survey 2011 were included in this study. Principal component analysis was used to develop a WRI, and households were classified as WASH poorest, poorer, middle, richer, and richest. A hot spot analysis was conducted to assess whether and how high-risk WASH practices and child diarrhea were geographically c...

Handwashing (HW) with soap is considered the most cost-effective intervention for reducing the risk of child diarrhea, but reliable measurement of HW behaviors is difficult. This study examined the association between proxy HW measures and child diarrhea by analyzing nationally representative household survey data from 25 countries in sub-Saharan Africa (n = 212,492). The main explanatory variable was the HW ladder, representing a varying level of availability of HW materials in the household, and the outcome variable was a 2-week prevalence of child diarrhea. We estimated the prevalence ratio of child diarrhea between children with a basic HW station and without a HW place. Our analysis revealed that availability of water and soap at a HW place was associated with both increased and decreased prevalence ratios: 0.89 (95% CI 0.79–0.99) in Chad, 0.82 (0.69–0.97) in Mauritania, 1.30 (1.02–1.66) in Burkina Faso, and 1.67 (1.20–2.33) in Ghana. After controlling for country-fixed effects, the prevalence ratio was 0.95 (0.92–0.99), suggesting a protective effect of having a HW station with water and soap. Availability of HW resources is an important indicator to prevent child diarrhea, and HW promotion programs should be tailored to the unique context of each country.
