We translated and adapted the WOMAC index into Arabic to suit Tunisian people. The translated questionnaire is reliable but not valid in its original form. We propose the use of a modified version of PF subscale of the WOMAC, although the psychometric properties of this instrument must be examined in a larger population.
We translated into Arabic language and adapted the SF-36 scale for use in Tunisian population. The Arabic version is reliable and valid. Although the scale was validated in a Tunisian population, we expect that it is suitable for other Arab populations, especially North Africans. Further studies are needed to confirm such a hypothesis.
Our survey demonstrated the beneficial effect of combining dietary measures and physical training in obese patients. In addition to weight loss, the programme enabled a reduction in the patients' body fat mass and abdominal obesity, a correction of metabolic disorders and an improvement in aerobic capacity. The improvement in all these parameters also enhanced the patients' psychological status and quality of life. The addition of strength training produced notable improvements in weight loss, arm muscle strength and abdominal obesity.
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.
