Prevalence of Musculoskeletal Complaints Among Dentists in Some Egyptian Cities

Background: Musculoskeletal complaints represent a significant occupational health issue in dentistry. In Egypt , data about the prevalence and risk factors of this problem are little. The aim of the study was to assess the prevalence of musculoskeletal (MSK) complaints among dentists in some Egyptian cities ,evaluate the influence of personalcharacteristics, physical and psychological risk factors at work and health status on the occurrence of MSK complaints and to detect the association between MSK complaints and other contributing factors in the development of sickness absence among dentists. Methods: A self-administered questionnaire was distributed to a random sample of 350 dentists in 3 cities of Egypt (Cairo , Al-mehalla El-kobra and El-mansoura).The questionnaire involved information on the respondent’s individual characteristics, job history, physical and psychosocial risk factors at work, general health status, and theoccurrence of musculoskeletal complaints.Results: Occupational neck and low-back pain were the most prevalent MSK complaintsamong dentists in the past 12 months in Egypt (75.1% and 58.5%, respectively). On the other hand low-back pain was the most prevalent chronic MSK complaints (11.4%) followed by chronic neck pain (7.4%). The occurrence of MSK pain was associated with at least one work- related physical load. Especially important was awkwardposture followed by improper workplace ergonomics, prolonged static posture, and repetitive movements .High job demands were associated with shoulder and hand/wrist complaints (OR= 2.26 and 2.17, respectively) . In this study, 27.4% of the respondents reported sickness absence . Chronic low-back pain was the only complaint thatincreased the risk of sickness absence (OR= 4.83). BMI >30, age > 40 years, perceived moderate general health, need for recovery and basic education were significant contributing factors for sickness absence. Conclusions: MSK complaints are a significant occupational health problem among dentists in some Egyptian cities. Interaction of physical load, psychosocial load, general health conditions, and personal criteria in developing the MSK pain require integratedpreventive strategies to minimize their impacts.
