Urban health extension program model housing and household visits improved the utilization of health Services in Urban Ethiopia: a community-based cross-sectional study

Abstract Background The government of Ethiopia launched an innovative program called Urban Health Extension Program (UHEP) in 2009, aims to produce better health outcomes to the urban populations using urban health extension professionals (UHE-ps) by enabling households to implement most health intervention packages designed by the government, which is referred to as model households (practice and implement at least 75% of the training provided by UHE-ps on UHEP packages). The objective of this study was to assess health service use and its associated factors. Methods A community-based cross-sectional study was conducted to assess the health service use in Addis Ababa. Structured questionnaires were filled out by 1086 women, and a binary logistic regression was performed. Results Urban health extension professionals performed home visits to 57.1% (95% CI (confidence interval) =54.2 to 59.8%) of the households. Mothers who had heard of the program (had information about UHEP) were 2.13 times more likely to visit the health center (HC) (AOR (adjusted odds ratio) =2.13, 95% CI = 1.36 to 3.32) than mothers who had not heard of the program. Mothers from model households were 2.12 times more likely to visit the HC (AOR = 2.12, 95% CI = 1.16 to 3.88) than mothers from non-model households. Mothers whose households were visited by the UHE-ps were 1.89 times more likely to visit the HC (AOR = 1.89, 95% CI = 1.22 to 2.94) than mothers whose households were not visited. Similarly, mothers who were in the reproductive age group (18 to 49 years) were 1.74 times more likely to visit the HC (AOR = 1.74, 95%CI = 1.12 to 2.71) than mothers above 49 years old. Conclusions Model households and mothers in the reproductive age group exhibited significant associations with health service use. Sustaining the practices of graduated and certified model households is essential to maximize the benefits of the UHEP’s activities regarding health service use. Regular home visits to both model and non-model households are essential to scale up health service use and design re-graduation or other sustainable options for already graduated households

Prevalence and Trends of Drinking Water Disinfection Byproducts-Related Cancers in Addis Ababa, Ethiopia

Background: Disinfection byproducts (DBPs) from chlorinated drinking water have been linked to an increased risk of cancer in the bladder, stomach, colon, and rectum. No studies showed the independent trends and prevalence of these cancers in Ethiopia. Therefore, this study aimed to determine the prevalence and trends of disinfection byproducts-related cancers in Addis Ababa, Ethiopia. Methods: Data were collected from the Addis Ababa Cancer Registry. Spatial data sets were produced and classified into households receiving chlorinated surface water and less chlorinated groundwater. The Cochran-Armitage trend test was used to evaluate whether there was a disinfection byproducts-related cancers (DBRCs) trend among communities receiving chlorinated water. Negative binomial regression was used to analyze the incidence rate. Results: A total of 11, 438 cancer cases were registered between 2012 and 2016, and DBRCs accounted for approximately 17%. The majority of the total cancer cases were female; 7,706 (67%). The prevalence of DBRCs was found to be higher in communities supplied with chlorinated water. From 2012 to 2016, the trend of colon cancer increased (β = 10.3, P value = .034); however, esophageal cancer decreased (β = −6.5, P value = .018). Approximately 56% of colorectal cancer patients and 53% of stomach cancer patients are known to be using chlorinated surface water for drinking regularly. In addition, approximately 57.1% and 54% of kidney and bladder cancer patients, respectively, used chlorinated surface water. Conclusion: The prevalence of DBRCs in this study was found to be high. The colon cancer trend increased substantially from 2012 to 2016. The prevalence of DBRCs was higher in communities supplied with chlorinated surface water. Similarly, the prevalence of DBRCs was higher among males than females. Further study is required to validate the association between DBRCs and water chlorination

Trihalomethanes and physicochemical quality of drinking water in Addis Ababa, Ethiopia

Background: Trihalomethanes (THMs) are the most dominant fraction of all the byproducts formed during chlorination of water. Disinfection by product (DBP) formation in water is a function of numerous factors, including pH, temperature, residual chlorine, source water characteristics, and organic matter. No study has determined the THM level in the drinking water supply of Addis Ababa, Ethiopia. Methods: A cross-sectional design was conducted to collect water samples in the water supply distribution networks of Addis Ababa, Ethiopia. Twenty-one (21) sampling stations yielded a total of one hundred twenty (120) samples of drinking water. The sample handling and collection procedures were carried out in accordance with USEPA guidelines. A DB-5 capillary column was used to separate the THMs, which were detected using GC-ECD (gas chromatography-electron capture detector). Spectrophotometric and in situ methods were used for physicochemical parameters. Redundancy analysis (RDA) was used for data analysis of trihalomethanes and environmental variables using CANOCO 4.5. Results: The mean concentration of total trihalomethanes in drinking water in Addis Ababa was 76.3 μg/L. The concentration of chloroform in the drinking water supply in Addis Ababa, Ethiopia, ranged between 4.03 and 79.4 μg/L. The mean total THMs in the Legedadi and Gefersa water supply systems were 77.4 μg/L and 69.66 μg/L, respectively. The residual chlorine, phosphates, UV absorbance at 254 nm, and combined chlorine had positive correlations with THM formation. However, electron conductivity had a negative correlation with THM formation. Conclusions: Chloroform contributed the most to TTHMs in nearly all samples. The residual chlorine, UV absorbance, phosphate and hardness as calcium, and electron conductivity were found to be the main predictors determining the abundance and distribution of trihalomethanes. The monitoring and regulation of the THMs is required on a regular basis to analyse trends and guide the water treatment and distribution system
