Recently, the beneficial effects of ginger on obesity is taken into consideration. Albeit, it seems that the anti-obesity effect of ginger and its mechanism of action has not yet been reviewed. Therefore, the aim of this study was to systematically review the effect of Zingiber officinale Roscoe on obesity management. Databases including PubMed, Scopus, Google scholar, and Science Direct were searched from 1995 until May 2017 using the definitive keywords. Searching was limited to articles with English language. All of the relevant human and animal studies and also in vitro studies were included. Review articles, abstract in congress, and also other varieties of ginger were excluded. Eligibility of included articles were evaluated by 3 reviewers, which also extracted data. Articles were critically assessed individually for possible risk of bias. Twenty-seven articles (6 in vitro, 17 animal, and 4 human studies) were reviewed. Most of the experimental studies supported the weight lowering effect of ginger extract or powder in obese animal models, whereas the results of the available limited clinical studies showed no changes or slight changes of anthropometric measurements and body composition in subjects with obesity. Ginger could modulate obesity through various potential mechanisms including increasing thermogenesis, increasing lipolysis, suppression of lipogenesis, inhibition of intestinal fat absorption, and controlling appetite. This review article provides some convincing evidence to support the efficacy of ginger in obesity management and demonstrates the importance of future clinical trials.

The carrying of schoolbags by primary school children and their musculoskeletal symptoms were investigated. The results provide evidence that the current weight limit may not be appropriate for younger school children, and that such guidelines should consider a broader combination of the factors that influence the use of schoolbags.

Background: Physical activity (PA) programs are inexpensive, non-pharmaceutical and universally accessible options with demonstrated efficacy in reducing menopausal symptoms. The purpose of this study was to determine the effectiveness of a behavioral strategy for initiating and sustaining PA with the hope to reduce or eliminate menopausal symptoms. Methods: Menopausal and perimenopausal women (n=190) were randomly assigned to intervention (n=95) and non-intervention (n=95) groups using a random-numbers table. The intervention group consisted of 18 neighborhood network subgroups, each consisting of five to six women known to one another. They participated in a 12-week regular PA program, augmented by eight interactive group education and discussion sessions. The Menopause Rating Scale (MRS) self-report instrument was used to determine perceived severity of menopausal symptoms. Results: The intervention group showed a significant reduction in the frequency and severity of menopausal symptoms (P < 0.001). Those whose symptoms rated severe/very severe for hot flushes were reduced from 30.1% to 11.8%. Also, participants whose sleep problems and joint discomfort rated severe/very severe declined from 28% to 6.5% and joint discomfort rated severe or very severe was reduced from 52.7% to 4.4%, respectively. Conversely in the nonintervention group, hot flushes, sleep problems and joint problems got significantly worse(P < 0.05). Conclusion: Implementing educational program that increases awareness of PA benefits in combination with existing neighborhood networks that facilitate communication and cooperation may increase PA levels and decrease menopausal symptoms. Such networks offer alow-cost means of improving quality of life (QOL) for perimenopausal and menopausal women.
