Background: Skin diseases are among the most frequent diseases affecting people of all ages, and cause a significant burden on patients and the healthcare system. The pattern of these diseases varies from country to country, region to region, and community to community due to different factors. However, there is no study showing a pattern of skin diseases and associated factors in the study area. Objective: To assess the proportion of skin diseases and associated factors at a primary hospital in Bahir Dar from June 2020 to May 2021. Method: A hospital-based, cross-sectional study was conducted. Applying Slovin's formula on study population of 2028, the sample size was calculated to be 338. A pre-designed data collection format was used to extract demographic and diagnostic information from the patients’ medical cards and residents’ logbooks. A systematic random sampling of the population data was performed. A pre-coded data was cleaned, entered into Excel, and exported in to SPSS 20 for analysis. Analysis was done using descriptive statistics. Chi-Square and Fisher’s Exact Tests were used to determine the strength of association. The level of significance was set at a P value < 0.05. Result: In this study, the most common skin disease categories were dermatitis (23.0%), fungal infections (20.5%), bacterial infections (10.4%), scabies (9.6%), and pigmentary disorders (8.7%). Age, sex, and seasons have statistically significant associations with various skin conditions. Conclusion: The study has shown the most common skin disease categories and specific skin diseases in the area of study. It has also demonstrated that variables including age, sex, and season have significant associations with various skin diseases. Knowledge of the extent of these skin disorders and associated factors is crucial for determining priorities for resources, developing public awareness campaigns and preventative measures in resource-constrained settings like ours.
