This meta-analysis revealed that moderate-to-severe SDB during pregnancy may be associated with most of adverse perinatal outcomes. Further well-designed studies are warranted to confirm our findings.

Results from recent trials assessing the effect of vitamin D supplementation on the prevention of childhood acute respiratory infections (ARI) have been inconsistent. In the present study, we determined whether vitamin D supplementation prevents ARI in healthy children and repeated infections in children with previous ARI. We conducted a systematic literature search using MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials. The search included only randomised controlled clinical trials (RCT) comparing vitamin D supplementation with either placebo or no intervention in children younger than 18 years of age. We identified seven RCT and found that the summary estimates were not statistically significantly associated with a reduction in the risk of ARI (relative risk (RR) 0·79, 95 % CI 0·55, 1·13), all-cause mortality (RR 1·18, 95 % CI 0·71, 1·94), or the rate of hospital admission due to respiratory infection in healthy children (RR 0·95, 95 % CI 0·72, 1·26). However, in children previously diagnosed with asthma, vitamin D supplementation resulted in a 74 % reduction in the risk of asthma exacerbation (RR 0·26, 95 % CI 0·11, 0·59; test of heterogeneity, I 2 ¼ 0·0 %). Our findings indicate a lack of evidence supporting the routine use of vitamin D supplementation for the prevention of ARI in healthy children; however, they suggest that such supplementation may benefit children previously diagnosed with asthma. Due to the heterogeneity of the included studies and possible publication biases related to this field, these results should be interpreted with caution.

This pilot project in Zhejiang Province, China, aimed at improving the nutrition and health status of students, school personnel and parents, and developing a model project for nutrition interventions for the development of health-promoting schools (HPS) in China. Three primary and three secondary schools participated. Interventions included establishing school-based working groups, nutrition training for school staff, distribution of materials on nutrition, nutrition education for students, student competitions, school-wide health promotion efforts and outreach to families and communities. Results of a pre- and post-intervention survey one and a half years apart showed improvements in nutrition knowledge, attitudes and behavior among all target groups. Primary school students at the pilot schools made the greatest knowledge gains in the areas of Chinese dietary guidelines (increased from 49.2 to 78.0%, p < 0.01) and adequate dietary principles (increased from 42.9 to 68.0%, p < 0.01). Scores of secondary school students who reported liking school lunches rose at pilot schools from 17.9 to 45.2% (p < 0.01). School staff at control schools who reported taking breakfast declined from 81.4 to 66.6% (p < 0.01), while staff who reported taking lunch at school increased in pilot schools from 87.5% at baseline to 93.9% (p < 0.01). The largest increases in nutrition knowledge among all target groups occurred among parents and guardians. At the pilot schools parents increased their knowledge in the areas of nutritional deficiencies (from 35.0 to 66.2%, p < 0.01) and nutrient-rich foods (from 38.8 to 66.8%, p < 0.01). Talks with target groups confirmed changes in attitudes and behavior, and school visits revealed improvements to school facilities and school health services, establishing of school policies and a positive school climate. This study suggests that nutrition can effectively serve as an entry point to establish HPS in China and that the HPS concept is feasible to improve the dietary knowledge, attitudes and behavior of students, parents and school personnel.

Background In early 2020, over 80,000 cases of coronavirus disease (COVID-19) were confirmed in China. Public prevention and control measures, along with efforts from all sectors of society, were undertaken to control and eliminate disease transmission. Objective This paper describes Chinese citizens’ response to the epidemic, the preventive measures they implemented to avoid being infected, and the public strategies that were carried out by the government, health workers, etc. We also discuss the efficacy of these measures in controlling the epidemic in China. Methods Information on the responses and behaviors of Chinese citizens were collected through a cross-sectional, internet-based survey using Dingxiang Doctor’s public account on WeChat. Information on public strategies implemented by all sectors of society to control the epidemic and data on new COVID-19 cases were collected from the internet, mainly from government websites. Standard descriptive statistics and multivariate logistic regression analyses were conducted to analyze the data. Results A total of 10,304 participants responded to the survey, with 10,198 valid responses; 74.1% (n=7557) were female and 25.9% (n=2641) were male. Overall, 98.2% (n=10,013) of participants paid high or very high attention to the epidemic, with WeChat being their main information source (n=9400, 92.2%). Over half the participants (n=5878, 57.7%) were confident that the epidemic could be curbed in China; 92.4% (n=9427) opened windows for ventilation more frequently than usual; 97.9% (n=9986) used masks in public; 95.7% (n=9759) avoided large crowds and stayed at home as much as possible; and 97.9% (n=9988) washed their hands more often than usual. Women were more likely to practice these behaviors than men (P<.001). With a series of strict public control measures, like nationwide health education campaigns, holiday extensions, the Examine and Approve Policy on the resumption of work, close management of working and living quarters, a health QR (Quick Response) code system, community screening, and social distancing policies, the number of new cases have decreased dramatically since February 12, 2020. Conclusions The methods employed by Chinese citizens and authorities have effectively curtailed the spread of COVID-19, demonstrating that this pandemic can be brought under control as long as the right measures are taken.
