The most frequent dysergonomic risk in the construction sector is the adoption of forced postures that contribute to the development of musculoskeletal disorders (MSDs) that affect the worker’s quality of life. The purpose of the study is to establish the possible chronic occupational pathologies that could produce alterations to the worker’s health, considering the variable of age, gender, size, among others. The methodological application is quantitative and qualitative for a finite sample of 538 construction workers. A questionnaire was applied for data collection, allowing the detection and analysis of musculoskeletal discomfort in different areas of the body. The risk assessment for forced postures is determined by means of the ISO 11226:2014 method, in order to establish the level of postural exposure. With the information gathered, it can be established that workers between 30 and 40 years old are more likely to suffer from a pathological clinical picture, while those between 60 and 70 years old have a lower probability of developing MSDs, due to the body control during the development of each task to be performed, for avoiding overexertion and exposure during the working day.
