The objective of this work was to establish the bibliometric profile of Tunisian theses in ‘general surgery’ and to describe their themes, their study designs, and their writing quality. This is a retrospective descriptive bibliometric study, covering all the theses in medicine in the specialty of ‘general surgery’, defended in the four medical faculties of Tunisia, during the forty last years from 1980 to 2019. During the study period, 739 theses in ‘general surgery’ were discussed in Tunisia, with an average of 19 theses per year. The most studied research topic was emergencies (41%), followed by common surgical pathologies (26%) and digestive oncology (21.5%). Descriptive studies and case studies represented the majority of study designs with respective proportions of 56.9% and 40.6%. Only 20.7% of these theses had a scientific writing quality deemed satisfactory. The least respected elements in writing their summaries were statistical (confidence intervals and standard deviations) and documentary (keywords). Despite the plethora of themes of Tunisian theses in ‘general surgery’, their basic methodology and their editorial non conformity require the educational reform of the dissertations, both doctoral students and supervisors, by strengthening their skills in research methodology and scientific communication written.
Aim:To investigate differences in attitude toward physical activity in normal-weight, overweight, and obese adolescents.Materials and Methods:We conducted a cross-sectional survey carried out in 2009/2010. It concerned randomly selected schoolchildren of colleges of Sousse in seventh and ninth grade. The sample was composed of 4003 schoolchildren. A questionnaire was used to evaluate habits and perception of physical activity, and we took anthropometric measurements of height and weight.Results:Among schoolchildren who performed a recommended level of physical activity, there was no significant difference in perceptions according to weight status. However, among those who did not practice physical activity, obese participants had significantly less positive perception. Overweight and obesity significantly increase the risk of negative perception of physical activity practice among participants who do not do the recommended level of physical activity. However, this association becomes non significant among those who practice recommended level of physical activity. The same findings were observed after adjustment by age and sex.Conclusion:Negative attitudes among inactive children may favor the development of a vicious circle perpetuating physical inactivity among normal-weight and overweight children.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
