Background: Diarrhoea remains a major cause of morbidity and mortality in children under 5 years in sub-Saharan Africa. Of the three East African countries, Uganda has the worst mortality rate in children < 5 years, with 22% of these deaths attributed to diarrhoea. For proper planning and implementation of control, an understanding of the prevalence and determinants of the disease is crucial. This study assessed the prevalence of diarrhoea and related risk factors among children < 5 years in Pajule Subcounty, Pader District in northern Uganda. Methods: A cross-sectional survey was conducted in April 2018, covering 244 randomly selected households having children < 5 years old in the study area. A semi-structured questionnaire was used to interview the households about diarrhoeal history in their children in the last 2 weeks preceding the survey, and on the risk factors predisposing children to diarrhoeal infections. Bivariate and multivariate logistic regression analyses with a 95% confidence interval and p < 0.05 was used to identify the risk factors associated with childhood diarrhoeal disease. Results: We found a prevalence of diarrhoea of 29.1% [95% CI (23.7-35.0)] among children < 5 years in Pajule Subcounty during the 2 weeks preceding the survey. Use of unprotected water sources, age of child caretaker, child weaning time and family size had significant associations with diarrhoeal morbidity. Conclusion: The prevalence of childhood diarrhoea among children < 5 years of age in rural settings of Pajule Subcounty was higher than the Ugandan national average. Use of unprotected water sources, age of child caretaker, child weaning time and family size were identified as predictors of diarrhoeal occurrence. These findings underscore the need for improving access to clean water and providing community health education as the best methods for fighting childhood diarrhoea in the study area.
Ruspolia differens (Serville) (Orthoptera: Tettigoniidae, Conocephalinae) (its common names including ‘African edible bush‐cricket’, ‘edible grasshopper’, and ‘nsenene’) is an important source of food for humans in East Africa, but its ecology and biology are poorly understood. We explored the host plants of R. differens with a series of no‐choice and multiple‐choice laboratory experiments using 18 local common grass and sedge species in Uganda. In no‐choice experiments, the degree of acceptance differed significantly among the studied plant species, but in only three species were leaves rejected and in one species were inflorescences rejected. The pattern of acceptance among plant species was different in the local vs. swarming populations. Leaves were generally more accepted by the local population, whereas inflorescences were generally more accepted by the swarming population. Both leaves and inflorescences were more readily accepted by males than by females. According to the multiple‐choice experiments, R. differens preferred inflorescences over leaves. Our results demonstrate that R. differens is a facultatively oligophagous grass‐specialist, which has a clear preference for certain grass or sedge species (especially inflorescences), but it accepts many host plants if the preferred ones are not available. To preserve viable natural populations of R. differens in East Africa in the long term, our results draw special attention to the availability of grasslands where accepted and preferred host plants are available year‐round.
Background: Diarrhoea remains a major cause of morbidity and mortality in children < 5 years in sub-Saharan Africa. Uganda has the worst mortality rate in children < 5 years among the three East African countries, with 22% of these deaths attributed to diarrhoea. For proper planning and implementation of control interventions, an understanding of the prevalence and determinants of the disease is crucial. This study assessed the prevalence of diarrhoea and related risk factors among children aged < 5 years in Pajule sub-county in Pader district in northern Uganda. Methods: A cross-sectional survey was conducted covering 244 randomly selected households having children < 5 years old in the study area. A semi-structured questionnaire was used to interview the households about diarrhoeal history in their children in the last two weeks preceding the survey, and on the risk factors predisposing children to diarrhoeal infections. Descriptive statistics was used to summarize the risk factors whereas bivariate and multivariate logistic regression analyses (95% confidence interval and p < 0.05) were used to identify the risk factors associated with childhood diarrhoea.Results: We found a prevalence of diarrhoea of 29.1% among children < 5 years of age in Pajule sub-county during the two weeks preceding the survey. Multivariate logistic regression revealed significant associations between diarrhoeal prevalence and use of unprotected water sources (adjusted Odd Ratio, aOR=2.866, 95% CI: [1.431 – 5.741]), presence of animals in respondents’ homes (aOR=3.950, 95%CI: [1.399 – 11.156]) and infrequent hand washing practices (aOR=2.737, 95% CI: [1.304 – 5.743]). Conclusion: The present study identified a high prevalence of diarrhoea among children < 5 years of age in Pajule sub-county, higher than the Ugandan national average. Extensive use of unprotected water sources, animals’ presence in homes and poor hand washing practices had significant associations with diarrhoeal occurrence. These findings underscore the need for continuous community health promotion emphasizing good hand washing practices and interventions that target improvement of hygiene practices at homes as the best methods for fighting childhood diarrhoea in the study area.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
