Aim: This study aimed to investigate the effect of circadian rhythm stability and amplitude on musculoskeletal disorder prevalence and work–family conflict among nurses. Design: This cross‐sectional study was conducted on 386 nurses working in three hospitals, in Shahroud, Iran. Method: The data were collected using the Circadian Rhythm Inventory, Nordic Musculoskeletal Disorders, and Carlson Work‐Family Conflict questionnaires. Results: The highest prevalence of musculoskeletal disorders was reported in the lower back (68.4%), upper back (65.5%) and shoulders (53.6%), respectively. No significant relation was found between circadian rhythm stability and amplitude, and musculoskeletal disorders prevalence. The nurses who could not overcome drowsiness reported more Work Interference with Family (WIF), Family Interference with Work (FIW) (time‐based) and FIW (strain‐based) compared to the nurses who overcame drowsiness. In addition, the appropriate nurses for shift work experienced less WIF, FIW (behavioural‐based) and WIF (strain‐based) compared to the nurses who could not work overtime or at night.

There has been a growing interest in assessing the condition and quality of life in older adult population, and factors contributing to it. In this context, fear of falling syndrome is introduced as one of the main factors that can affect the quality of life in the general adult population. However, little is known about the relationship between fear of falling and other disorders in older adults, particularly among the Middle East population. Here we investigated the associations between fear of falling and anxiety and depression disorders. A standardized questionnaire was used to assess sociodemographic variables and physical health condition. Subsequently, fear of falling and anxiety and depression scales were assessed using the Falls Efficacy Scale International and the Hospital Anxiety Depression Scale, respectively. Our results highlighted the high risk of having anxiety and depression disorders among older adults. The findings also indicate that physical and mental health disorders play a significant role in incident fear of falling. Therefore, improving mental health might lend controlling fear of falling syndrome, which then preventing falls incident and subsequent injury in older adult population. [ABSTRACT FROM AUTHOR]
