| Résumé : | [BDSP. Notice produite par INIST-CNRS R0xhf3rS. Diffusion soumise à autorisation]. Background : Spot checks are becoming a popular method to assess hygiene behaviours ; however, little is known about their repeatability or predictability. We evaluated the within-household repeatability of hygiene indices created from spot checks and their ability to predict incidence of diarrhoea in young Guatemalan children. Methods : We observed hygiene behaviours in 588 households in four rural Guatemalan communities over 36 months. Four indices related to drinking water (DWI ; score=0-3), food (FI ; score=0-3), personal hygiene (PHI ; score=0-3), and domestic household hygiene (DHI ; score=0-6) and one summary hygiene index (SHI ; range 0-15) were created. Morbidity of 694 children aged birth to 36 months living in the study households was assessed using biweekly recall. Intraclass correlation coefficients were calculated to assess within-household repeatability ; the generalized estimating equations approach was employed to analyse diarrhoea morbidity. Results : Households were observed a mean of 22.1+/-11.2 times. All indices decreased with duration of follow-up (SHI=-0.67+/-0.05 points/year ; WI=-0.04+/-0.01 ; FI=-0.07+/-0.01 ; PHI=-0.21+/-0.01 ; DHI=-0.37+/-0.02 ; all P<0.05). Intraclass correlations were low to moderate (SHI=0.35-0.51 ; DWI=0.17-0.21 ; FI=0.16-0.18 ; PHI=0.27-0.32 ; DHI=0.27-0.38). Six separate spot checks would be needed to estimate a household's underlying level of hygiene within 20%. SHI and PHI scores were inversely associated with diarrhoea morbidity (both P<0.05). Conclusions : Hygiene indices created using spot checks can be a rapid and efficient method for assessing hygiene and useful for predicting diarrhoea morbidity in young children. Multiple measures are required to accurately estimate the true hygiene pattern of a household. |
