Background: The carcinogenic properties of arsenic make it one of the most hazardous chemicals globally. Nevertheless, the exact level of human exposure to arsenic and the associated risks of cancer and non-cancer effects through different pathways in Ethiopia are still uncertain.
Objective: The primary aim of this study was to evaluate the risk of both cancer and non-cancer outcomes among children and adults who have been exposed to arsenic through drinking water in the Adami Tulu Jido Kombolcha district of Ethiopia.
Article Synopsis
- - The study examined the prevalence of arsenic-induced skin lesions in the Adami Tulu Jido Kombolcha district, Ethiopia, using a community-based cross-sectional design with 403 participants from June 2-20, 2022.
- - Results showed that the prevalence of arsenicosis was 2.2%, with keratosis being the most common manifestation (55.6%), followed by hyperpigmentation (33.3%) and hyperkeratosis (11.1%).
- - Significant factors associated with these skin lesions included the consumption of well water, smoking, and chewing khat, indicating a need for more research on arsenic exposure and its health risks.
Generalized estimating equations (GEE), proposed by Liang and Zeger (1986), provide a popular method to analyze correlated non-Gaussian data. When data are incomplete, the GEE method suffers from its frequentist nature and inferences under this method are valid only under the strong assumption that the missing data are missing completely at random. When response data are missing at random, two modifications of GEE can be considered, based on inverse-probability weighting or on multiple imputation.
