Nine(50%) studies were randomized controlled trials. Five(27.8%) studies utilized biopsy to examine the effects of physical activity on hepatic histology. The most commonly employed imaging modality to determine change in hepatic steatosis was hydrogen-magnetic resonance spectroscopy. Only two studies examined the effects of low impact physical activity for patients with significant mobility limitations and one compared the efficacy of aerobic and resistance exercise. No studies examined the exact duration of exercise required for hepatic and metabolic improvement in NAFLD.CONCLUSION: While exercise improved hepatic steatosis and underlying metabolic abnormalities in NAFLD, more studies are needed to define the most beneficial form and duration of exercise treatment.展开更多

Participants were 90,712 primary, junior middle, and junior high school children(boy: 47%; girl: 53%), recruited from 1204 rural and urban schools across 32 administrative provinces and regions in the Mainland of China. Main outcomes were(a) average MVPA minutes per day in the previous 7 days by self-reports and(b) percentage meeting MVPA recommendations.Results: Average MVPA time was 45.4 min/day, with boys having more MVPA(47.2 min/day) than girls(43.7 min/day) overall and across the 3 school grade categories. About 30% of participants met MVPA recommendations, with a higher percentage of boys(32%) than girls(28%) overall and across the 3 grades categories. Urban school children outperformed rural children in terms of MVPA time. Overall, boys were more likely to meet MVPA recommendations(adjusted odds ratio(a OR) = 1.19, 95% confidence interval(CI): 1.16–1.22) compared with girls; children in higher grades(junior middle(a OR = 0.92, 95%CI: 0.87–0.98) and junior high(a OR = 0.59, 95%CI: 0.53–0.66)) were less likely to meet recommendations compared with primary school children. The odds of meeting recommendations did not differ between urban and rural children(p = 0.07),but urban boys were found to be more likely to meet recommendations compared with rural boys(a OR = 1.14, 95%CI: 1.06–1.19).Conclusion: Overall, the average MVPA minutes per day among Chinese school-aged children is low, and less than one-third of them meet MVPA recommendations. These results were most evident among junior middle and junior high school children and those living rural areas.展开更多
