|Bariatric surgery is highly recommended treatment for patients with severe obesity (i.e. BMI>40 kg/m2 or BMI>35 kg/m2 with at least one obesity related comorbid somatic condition). Engagement in health promoting behaviors, including regular exercise and healthy eating behaviors are related to maintenance of weight loss and physical and mental wellbeing after surgery. Adherence to these treatment guidelines in regard to physical exercise and eating habits varies among patients after bariatric surgery. Psychological factors are found to influence psychosocial outcome, weight loss and adherence to treatment guidelines in patients that have undergone bariatric surgery
High-impact journals are those considered to be highly influential in their respective fields. The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information. The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
