Introduction: Work-related musculoskeletal disorders (WMSDs) are described as discomforts experienced by the worker on the musculoskeletal and neurovascular systems. According to the Occupational Safety and Health Administration, nurses are in the 10 major occupations which have the high risk of work-related musculoskeletal disease. It is more relevant in less-developed countries because of prolonged hospital stays and increased patient loads. Aim of work: To estimate the prevalence of musculoskeletal complaints and its associated factors among nurses. Materials and Methods: A cross sectional study with comparative component was conducted among nurses working in Mansoura Children University Hospital during the period from January to May 2017. Data was collected using a questionnaire included personal, past and occupational histories. Furthermore, a Nordic Questionnaire was used to examine the prevalence of musculoskeletal complaints among the participants. Dutch Musculoskeletal Questionnaire was employed to study the possible associated ergonomic factors. Results: The prevalence of musculoskeletal complaints among nurses was 85.9 % .The most common sites were elbow (85.2%) followed by pelvis/ thigh (74.9%) and wrist (64.6%). Surprisingly the least site for pain was low back pain (37%). This prevalence was statistically lower among age group (30-<40 years old) compared to younger age group (80.0% versus 91.2%). It increased for continuous working ≥ 6 hours and shift work with adjusted odds ratio (2.59, 2.19; respectively).

Introduction: Shift work means working at times out of normal daylight hours (8:00 am to 2:00 pm) or work during the weekends. Also it refers to a work schedule that involves irregular or unusual hours, such as night work and rotating shift work, in contrast to normal daytime work. Shift workers prefer to eat fast foods and tend to have fewer meals over 24 hours. Security guards experience shifts that negatively affect their dietary behavior and nutritional status. Aim of work: To assess the effect of shift work on dietary habits and nutrients intake among the security guards at Mansoura University. Materials and methods: A cross sectional study of all (166) security guards at Mansoura University who were exposed to an interviewer-administrated questionnaire for socio-demographic data and occupational history, anthropometric measurement, evaluation of dietary habits and dietary survey. Results: Mean±SD of Body Mass Index (BMI) (34.6±8.8) and waist circumference (105.1±15.9 cm) were statistically significantly higher among night shift guards than those with other shifts. Number of meals was statistically significantly fewer (2 meals/day) but snacks number was significantly higher (> 3 snacks/day) among night shift guards. Night shift guards had the highest daily carbohydrate and fat intake and lowest daily protein intake with a statistically significant difference with other shifts. They also had the lowest daily intake of iron, calcium and vitamin. Conclusion: Security guards with night shift experienced few meals intake with more snacks during their shift with reduced intake of protein, iron, calcium and vitamin A and with increased carbohydrate and fat intake.
