Objective Smartphone addiction is a public health problem increasing with the technologic developments. It particularly affects the university students negatively in terms of psychological, physical, academic achievement and social relations. This study aims to investigate the relation of eating attitudes between smartphone addiction and internet gaming disorder, also the relation of smartphone addiction with obesity.Methods This cross-sectional and prospective study is consisted of 358 volunteer university students. Socio-demographic data form, Short Form of Smartphone Addiction Scale (SF-SAS), Eating Attitude Test (EAT), and internet gaming disorder scale were administered to the participants.Results Mean age of the participants was 22.27±3.10 years and 59.8% (n=214) were female. In terms of the variables “body mass index, body weight, faculty of the student, economic status of the family, and the people they live with together” were significantly different from controls. Also “monthly mobile phone invoice, EAT score, SF-SAS scores” were statistically different. A significant difference was found among “body weight groups” in terms of both EAT score and SF-SAS. According to the linear regression model variables of “gender, smartphone addiction, and school year” were determined as the predictors for EAT.Conclusion Our current study has revealed the relation between smartphone addiction and eating attitudes, and obesity. Smartphone addiction may lead to an increase in body weight, by affecting eating attitudes. Therefore, the effect of eating behavior disorders in the emergence of the smartphone addiction should be considered. Multi-disciplinary solutions are required to prevent this addiction that may increase over time.

Objective Functional neurogical symptom disorder (FNSD) is a somatic symptom disorder with loss of voluntary motor or sensory functions, which cannot be explained by another medical condition. The study aimed to examine the relationship of vasopressin and oxytocin in persistent type FNSD.Methods This study included 27 female patients between the ages of 20–57 who were diagnosed with FNSD according to DSM-5 and 27 healthy controls matched in terms of age and gender. Serum vasopressin and oxytocin levels were measured twice on the same day in fasting blood samples and the results were compared statistically.Results Vasopressin were lower in patients compared to controls while there was no difference between oxytocin levels. Childhood traumas were more common in patient group, and mean oxytocin level was lower in patients who exposed to childhood trauma, compared to controls. No significant difference was found between the groups in terms of vasopressin.Conclusion Changes in vasopressin and oxytocin balance in the pathogenesis of persistant FNSD, may likely to lead to physiological and behavioral consequences. Lower oxytocin levels may also be a marker of exposure to childhood trauma in FNSD. These neuropeptides plays important role in neuroendocrine balance of emotional behavior.
