Prevalence of diarrhea and associated risk factors among children under-five years of age in Eastern Ethiopia: A cross-sectional study

Background Diarrhea is recognized as a leading cause of morbidity and mortality among children under 5 years of age in low- and middle-income countries yet updated estimates of diarrhea incidence by age for these countries are greatly needed. We conducted a systematic literature review to identify cohort studies that sought to quantify diarrhea incidence among any age group of children 0-59 mo of age. Methods We used the Expectation-Maximization algorithm as a part of a two-stage regression model to handle diverse age data and overall incidence rate variation by study to generate country specific incidence rates for low- and middle-income countries for 1990 and 2010. We then calculated regional incidence rates and uncertainty ranges using the bootstrap method, and estimated the total number of episodes for children 0-59 mo of age in 1990 and 2010. Results We estimate that incidence has declined from 3.4 episodes/child year in 1990 to 2.9 episodes/child year in 2010. As was the case previously, incidence rates are highest among infants 6-11 mo of age; 4.5 episodes/child year in 2010. Among these 139 countries there were nearly 1.9 billion episodes of childhood diarrhea in 1990 and nearly 1.7 billion episodes in 2010. Conclusions Although our results indicate that diarrhea incidence rates may be declining slightly, the total burden on the health of each child due to multiple episodes per year is tremendous and additional funds are needed to improve both prevention and treatment practices in low- and middle-income countries.

Background We analyzed data from the baseline assessment of a large intervention project to describe typical handwashing practices in rural Bangladesh, and compare measures of hand cleanliness with household characteristics. Methods We randomly selected 100 villages from 36 districts in rural Bangladesh. Field workers identified 17 eligible households per village using systematic sampling. Field workers conducted 5-hour structured observations in 1000 households, and a cross-sectional assessment in 1692 households that included spot checks, an evaluation of hand cleanliness and a request that residents demonstrate their usual handwashing practices after defecation. Results Although 47% of caregivers reported and 51% demonstrated washing both hands with soap after defecation, in structured observation, only 33% of caregivers and 14% of all persons observed washed both hands with soap after defecation. Less than 1% used soap and water for handwashing before eating and/or feeding a child. More commonly people washed their hands only with water, 23% after defecation and 5% before eating. Spot checks during the cross sectional survey classified 930 caregivers (55%) and 453 children (28%) as having clean appearing hands. In multivariate analysis economic status and water available at handwashing locations were significantly associated with hand cleanliness among both caregivers and children. Conclusions A minority of rural Bangladeshi residents washed both hands with soap at key handwashing times, though rinsing hands with only water was more common. To realize the health benefits of handwashing, efforts to improve handwashing in these communities should target adding soap to current hand rinsing practices.

Diarrhoea and acute respiratory infection (ARI) are leading causes of mortality and morbidity in children under the age of five in developing countries. On the African continent, pneumonia (14%) and diarrhoea (17%) cause more child deaths than Malaria (16%), HIV/AIDS (4%), and measles (1%) combined. This paper set out to investigate the factors associated with the occurrence of diarrhoea and ARI incidence for children under five years in Uganda. We used a nationally representative Uganda Demographic and Health Survey (UDHS) (2006). Sampling was done in two stages. In the first stage 321 clusters were selected from among a list of clusters sampled in the 2005/06 Uganda National Household Survey (UNHS), 17 clusters from the 2002 Census frame from Karamoja, and 30 internally displaced camps (IDPs). In the second stage, households in each cluster were selected as per UNHS listing. In addition 20 households were randomly selected in each cluster. Questionnaires were used during data collection. During the analysis, a maximum likelihood probit model was used in order to ascertain the probability of occurrence of diseases. On average, 32% and 48% of children in the survey suffered from diarrhoea and ARI in the two weeks prior to the survey date. The occurrence was concentrated amongst children aged 0-24 months. Mother's education, especially at postsecondary level, reduced the probability of diarrhoea occurrence but had no effect on ARI occurrence. First hour initiation and exclusive breastfeeding reduced the probability occurrence of both diarrhoea and ARI. Other significant factors associated with the occurrence of both diseases include: regional and location differentials, wealth status, type of dwelling, mother's occupation, child age, and child nutritional status. Policy interventions should target female education, eliminate location and regional disadvantages, and educate the population to adopt breastfeeding practices recommended by the World Health Organization (WHO). The government should also ensure proper dwelling places for the population that are associated with favourable health outcomes. Other proper feeding practices together with breastfeeding (after six months), should be made known to the masses so as to reduce the number of children that are malnourished and growth retarded.
