ObjectivesThe purpose of our study was to explore the prevalence, and the role of mood, exercise frequency, age, and gender differences of exercise dependence. Methods: Regular exercisers (N = 409) completed a socio-demographic questionnaire, the Exercise Dependence Scale, and the Profile of Mood States. For data analyses, the participants were stratified for sex and age (age ranges = young adults: 18–24 years, adults: 25–44 years, and middle-aged adults: 45–64 years). Results: We found that: (a) 4.4% of the participants were classified as at-risk for exercise dependence; (b) the men and the two younger groups (i.e., young adults and adults) had higher exercise dependence scores; and (c) age, gender, exercise frequency, and mood state were related to exercise dependence. Conclusions: Our results support previous research on the prevalence of exercise dependence and reveal that adulthood may be the critical age for developing exercise dependence. These findings have practical implication for identifying individuals at-risk for exercise dependence symptoms, and may aid in targeting and guiding the implementation of prevention program for adults.

Preparing children through playful dramatization of the operative procedure, manipulation of medical instruments and psychologist's support may be useful in pediatric surgery structures.

This study adds new encouraging data, further supporting the potential use of melatonin premedication in reducing anxiety and improving compliance to induction of anaesthesia in children undergoing surgery. Nevertheless, further larger controlled clinical trials are needed to confirm the real effectiveness of melatonin as a premedicant agent in paediatric population. What is Known: • Although midazolam represents the preferred treatment as a premedication for children before induction of anaesthesia, it has several side effects. • Melatonin has been successfully used as a premedicant agent in adults, while data regarding effectiveness in children are controversial. What is New: • In this study, melatonin was as effective as midazolam in reducing children's anxiety in both preoperative room and at induction of anaesthesia.
