Acute respiratory symptoms and its associated factors among mothers who have under five-years-old children in northwest, Ethiopia

BACKGROUND@#Poor air quality of the household is likely to be the largest public health concern in resource-constrained countries. Exposure to household air pollution, poor working environment, and fuel type used at household level have been associated with respiratory symptoms. This study aimed to assess acute respiratory symptoms and its associated factors among mothers who have under five-years-old children in Gondar city, northwest Ethiopia.@*METHOD@#A cross-sectional study was carried out from February 15, 2019 to June 20, 2019. Study participants were selected using simple random sampling, and data were collected via face-to-face interviews. Binary logistic regression analysis was used to test the association of explanatory and outcome variables. Variables with p < 0.05 were considered as significantly associated with the outcome variable.@*RESULTS@#The prevalence of respiratory symptoms among mothers of under-five years-old children in this study was 46.1%. Education (vocational training compared to cannot read and write) (adjusted odd ratio (AOR) = 0.26 at 95% confidence interval (CI): 0.08-0.82), working in dusty environment (AOR = 2.90 at 95% CI: 1.39-6.08), wood fire use (AOR = 0.37 at 95% CI: 0.16-0.85), living in mud- and wood-walled houses (AOR = 0.53 at CI: 0.32-0.89), recent house painting (AOR = 1.95 at 95% CI: 1.03-3.69), new carpet (AOR = 2.02 at 95% CI: 1.08-3.77), pesticide use (AOR = 1.71 at 95% CI: 1.03-2.84), damp stain (AOR = 2.45 at 95% CI: 1.04-5.75), spending longer time in house for 6 to 11 h (AOR = 2.59 at 95% CI: 1.53-4.37) and 11 to 15 h (AOR = 3.47 at 95% CI: 1.87-6.43), and living less than 100 m from unpaved roads/streets (AOR = 4.35 at 95% CI: 2.64-7.18) were significantly associated with respiratory symptoms among mothers of under-five years-old children.@*CONCLUSION@#Respiratory symptoms were common among mothers who have under five-years-old children. Air quality improvement, fuel selection, and residential planning will help to reduce respiratory symptoms.

Sick building syndrome and associated risk factors among the population of Gondar town, northwest Ethiopia

BACKGROUND@#Sick building syndrome (SBS) consists of a group of mucosal, skin, and general symptoms temporally related to residential and office buildings of unclear causes. These symptoms are common in the general population. However, SBS symptoms and their contributing factors are poorly understood, and the community associates it with bad sprits. This community-based cross-sectional study was, therefore, conducted to assess the prevalence and associated factors of SBS in Gondar town.@*METHODS@#A community-based cross-sectional study was conducted from March to April 2017. A total of 3405 study subjects were included using multistage and systematic random sampling techniques. A structured questionnaire and observational checklists were used to collect data. SBS was assessed by 24 building-related symptoms and confirmed by five SBS confirmation criteria. Multivariable binary logistic regression analysis was used to identify factors associated with SBS on the basis of adjusted odds ratio (AOR) with 95% confidence interval (CI) and p < 0.05. The Hosmer and Lemeshow goodness of fit test was used to check model fitness, and variance inflation factor (VIF) was also used to test interactions between variables.@*RESULTS@#The prevalence of SBS in Gondar town was 21.7% (95% CI = 20.3-23.0%). Of this, the mucosal symptoms account for 64%, the general symptoms account for 54%, and the skin symptoms account for 10%. From study participants who reported SBS symptoms, 44% had more than one symptom. Headache (15.7%), asthma (8.3%), rhinitis (8.0%), and dizziness (7.5%) were the commonest reported symptoms. SBS was significantly associated with fungal growth in the building [AOR = 1.25, 95% CI = (1.05, 1.49)], unclean building [AOR = 1.26, 95% CI = (1.03, 1.55)], houses with no functional windows [AOR = 1.35, 95% CI = (1.12, 1.63)], houses with no fan [AOR = 1.90, 95% CI = (1.22, 2.96)], utilization of charcoal as a cooking energy source [AOR = 1.40, 95% CI = (1.02, 1.91)], cooking inside the living quarters [AOR = 1.31, 95% CI = (1.09, 1.58)], and incensing and joss stick use [AOR = 1.48, 95% CI = (1.23, 1.77)].@*CONCLUSION@#The prevalence of SBS in Gondar town was high, and significant proportion of the population had more than one SBS symptom. Headache, asthma, rhinitis, and dizziness were the commonest reported SBS symptoms. Fungal growth, cleanliness of the building, availability of functional windows, availability of fan in the living quarters, using charcoal as a cooking energy source, cooking inside the quarters, and incensing habit or joss stick use were identified as factors associated with SBS. Improving the sanitation of the living environment and housekeeping practices of the occupants is useful to minimize the prevalence of SBS.

Childhood intestinal parasitic infection and sanitation predictors in rural Dembiya, northwest Ethiopia

BACKGROUND@#Intestinal parasites are a common problem in the world. The greater proportion of infections is associated with poor water, sanitation, and hygiene (WASH). This study was conducted to assess intestinal parasites, WASH condition, and their association in rural Dembiya, northwest Ethiopia.@*METHODS@#A cross-sectional study was employed. Two hundred twenty-five children aged 6-59 months were included. Mothers were interviewed using a structured questionnaire, and the living environment was observed using checklists. Kato-Katz technique was used to determine the intensity of parasitic infections. Escherichia coli (E. coli) was used as a biological indicator for drinking water quality. Multivariable binary logistic regression analysis was conducted to identify WASH predictors of parasites on the basis of adjusted odds ratio (AOR) with 95% confidence interval (CI) and p < 0.05.@*RESULTS@#The prevalence of intestinal parasites was 25.8% (95% CI = 20.3-32.0%). Ascaris lumbricoides (78%), hookworm (12%), Hymenolepis nana (7%), Enterobius vermicularis (5%), Schistosoma mansoni (3%), Giardia lamblia (3%), and Trichuris trichiuria (2%) were identified infections. Intestinal parasites were associated with poor child hand washing practice [AOR = 3.86, 95% CI = 1.53, 9.75], unprotected water sources [AOR = 7.79, 95% CI = 3.30, 18.40], access to water below 20 l/c/d [AOR = 3.05, 95% CI = 1.28, 7.23], poor food safety[AOR = 4.33, 95% CI = 1.62, 11.58], and poor sanitation [AOR = 5.01, 95% CI = 1.56, 16.16].@*CONCLUSION@#A. lumbricoides, hookworm, H. nana, E. vermicularis, S. mansoni, G. lamblia, and T. trichiuria were identified. Child hand washing practice, service level of water supply, water sources, food safety, and sanitation were associated with intestinal parasites. WASH promotion is needed to prevent infections.
