| 1 | Report on Childhood Obesity in China (10): Association of Sleep Duration with Obesity显示文摘Objectives To explore the association of sleep duration with obesity among children in urban areas of China.Methods A total of 6 576 children(3 293 boys and 3 283 girls) aged 7-11 years were randomly selected from 36 primary schools in 6 metropolitan cities in China.A 7-day Physical Activity Recall was used to assess the sleep duration and physical activity level.The height,weight,waist circumference(WC) and percentage of body fat(%BF,as determined by bioelectrical impedance analysis technique) were measured by following the standardized operation procedures.The information on demography,lifestyle and eating habits was collected with a self-administered questionnaire from participants and their parents.Results The average sleep duration per night in the children was 9.7 h with the decreasing trends along with the increase of age(P<0.05).The sleep duration was negatively associated with body mass index(BMI) and WC in both boys and girls after adjustment for confounders(β value-0.23 and-0.82 for boys,-0.24 and-0.91 for girls,respectively,P<0.01).However,no significant association of sleep duration with %BF was found.Children who slept less than 9.0 h per night had a higher risk for overweight and obesity(OR=1.29,95% CI:1.01,1.64) and abdominal obesity(OR=1.38,95% CI:1.04,1.83) as compared with those who slept for 10.0-10.9 h.Conclusions Short sleep duration is associated with obesity.It is important to ensure adequate sleep duration of children and foster their healthy lifestyle at an early stage of life. | MENG Li Ping LIUAi Ling HU Xiao Qi ZHANG Qian DU Song Ming FANG Hong Yun MA Jun XU Gui Fa LI Ying GUO Hong Wei DU Lin MA Guan Sheng | 2012 | Biomedical and Environmental Sciences2012，25，2： | 16 |
| 2 | How Work Organization Affects the Prevalence of WMSDs: A Case-control Study显示文摘Objective In this study, we aimed at exploring the association between work-related musculoskeletal disorders(WMSDs) and work organization based on a case-control study. Methods A total of 1938 workers who claimed to suffer from WMSDs were selected from Beijing, Henan, Hubei, and the Guangdong province. The control group consisted of 2009 workers employed in similar industries without severe disease or musculoskeletal discomforts. We used a modified version of the questionnaire developed by the NMQ and the DMQ to investigate individual and work-related factors. Results A total of 13 variables(P<0.1) were selected by the chi-square test and finally, 7 variables entered into the equation, with 6 variables reaching statistical significance(P<0.05). The odds ratios(OR) of ‘work changing with season' and ‘sufficient rest time' did not reach 1(0.749 and 0.441, respectively). In addition, ‘sufficient rest time' seemed to be the stronger protective factor according to its higher standardized coefficient. And ‘repetitive work every minute', ‘constantly repetitive work'(every day), ‘shortage of site personnel', and ‘often switching shifts with others' seemed to be the risk factors. Conclusion Work organization may have comprehensive effects on the occurrence of WMSDs. This pattern of associations suggests that further investigation into the mechanism of how work organization affects the prevalence of WMSDs is required. | LIU Lu CHEN Song Gen TANG Shi Chuan WANG Sheng HE Li Hua GUO Ze Hua LI Jing Yun YU Shan Fa WANG Zhong Xu | 2015 | Biomedical and Environmental Sciences2015，28，9： | 11 |
| 3 | Risk Factors of Low Back Pain among the Chinese Occupational Population:A Case-control Study显示文摘Objective To explore the risk factors of low back pain among the Chinese occupational population in several major industries.Methods A total of 7200 subjects(3600 cases and 3600 controls) were randomly sampled from a cross-sectional study,and they were investigated for individual and occupational factors of low back pain.The potential risk factors were first selected by using chi-square tests.Secondly,collinearity diagnosis proceeded by using the Kendall's rank correlation.Finally,binary logistic regression model was used for multi-factor analysis.Results Collinearity diagnosis showed that there was a severe collinearity problem among the potential risk factors of low back pain.Logistic regression model included 20 variables with statistical significance.Bending neck forward or holding neck in a forward posture for long periods(OR=1.408) was the most important risk factor inducing low back pain in this study,followed by bending heavily with the trunk(OR=1.402),carrying out identical work almost for the whole day(OR=1.340).Additionally,sufficient normal break was a protective factor of low back pain.Conclusion Low back pain among the Chinese occupational population was associated with body height,occupation,work organization,physical work,working posture,and others.All these risk factors could be regarded as the indicators of low back pain,and some relevant preventive measures should be taken to reduce low back pain risk. | LI Jing Yun WANG Sheng HE Li Hua WU Shan Shan YANG Lei YU Shan Fa LI Li Ping WANG Jian Xin HUANG Yan Di | 2012 | Biomedical and Environmental Sciences2012，25，4： | 7 |

| 6 | Analysis of a Community-based Intervention to Reduce Heat-related Illness during Heat Waves in Licheng,China:a Quasi-experimental Study显示文摘Objective To reduce health-related threats of heat waves, interventions have been implemented in many parts of the world. However, there is a lack of higher-level evidence concerning the intervention efficacy. This study aimed to determine the efficacy of an intervention to reduce the number of heat-related illnesses. Methods A quasi-experimental design was employed by two cross-sectional surveys in the year 2014 and 2015, including 2,240 participants and 2,356 participants, respectively. Each survey was designed to include one control group and one intervention group, which conducted in Licheng, China. A representative sample was selected using a multistage sampling method. Data, collected from questionnaires about heat waves in 2014 and 2015, were analyzed using a difference-in-difference analysis and cost effectiveness analysis. Outcomes included changes in the prevalence of heat-related illnesses and cost-effectiveness variables. Results Relative to the control participants, the prevalence of heat-related illness in the intervention participants decreased to a greater extent in rural areas than in urban areas(OR=0.495 vs. OR=1.281). Moreover, the cost-effectiveness ratio in the intervention group was less than that in the control group(US$15.06 vs. US$15.69 per participant). Furthermore, to avoid one additional patient, the incremental cost-effectiveness ratio showed that an additional US$14.47 would be needed for the intervention compared to when no intervention was applied. Conclusion The intervention program may be considered a worthwhile investment for rural areas that are more likely to experience heat waves. Meanwhile, corresponding improving measures should be presented towards urban areas. Future research should examine whether the intervention strategies could be spread out in other domestic or international regions where heat waves are usually experienced. | LI Jing XU Xin WANG Jun ZHAO Yun SONG Xiu Ping LIU Zhi Dong CAO Li Na JIANG Bao Fa LIUQiYong | 2016 | Biomedical and Environmental Sciences2016，29，11： | 3 |

| 8 | Associations of Sedentary Time and Physical Activity with Metabolic Syndrome among Chinese Adults:Results from the China Health and Nutrition Survey显示文摘Objective This study aimed to determine the independent and joint associations of sedentary time(ST)and physical activity(PA) with metabolic syndrome(MetS) and its components among Chinese adults.Methods The study analyzed data from 4,865 adults aged ≥ 18 years who participated in the 2009 and2015 China Health and Nutrition Surveys(CHNS). Four types of leisure ST and three types of PA selfreported at baseline were collected. Multivariable logistic regressions were used to determine the independent and joint associations of ST and PA with the odds of MetS or its components.Results For independent effects, higher levels of television time and total leisure ST was associated with higher MetS risk [odds ratio(OR) 1.3, 95% confidence interval(CI) 1.1–1.6, P < 0.001;OR 1.4, 95% CI1.2–1.8, P < 0.001, respectively]. The MetS risk in the computer time > 7 hours/week(h/w) group was higher than that in the < 7 h/w group in(OR 1.5, 95% CI 1.2–1.9). Higher levels of moderate-to-vigorousintensity physical activity(MVPA) and total PA were associated with a lower MetS risk(OR 0.7, 95% CI0.6–0.9, P < 0.001;OR 0.8, 95% CI 0.7–0.9, P < 0.001, respectively). For the joint effects, compared with those reporting the lowest level of total leisure ST(< 14 h/w) and the most active tertile of MVPA(≥ 61.0 MET-h/w), participants reporting the most total leisure ST(≥ 35 h/w) and the lowest level of MVPA(0 MET-h/w) had the highest odds of MetS(OR 2.0;95% CI 1.4–2.7). Except for people reporting ST(14–21 h/w) within the most active tertile of MVPA, the associations in all other groups were significant.With the increase of TV time and decreased MVPA, the odds of MetS almost showed a curve acceleration.Conclusions MVPA and total PA have independent preventive effects, and sedentary behavior(mainly watching TV) has an unsafe effect on MetS and its components. Strengthening the participation of MVPA and combining the LPA to replace the TV-based ST to increase the total PA may be necessary to reduce the prevalence of MetS in Chinese adults. | BAI Jing WANG Yun ZHANG Xian Fan OUYANG Yi Fei ZHANG Bing WANG Zhi Hong DU Shu Fa WANG Hui Jun | 2021 | Biomedical and Environmental Sciences2021，34，12： | 2 |
| 9 | Automatic Identification of Clear-Air Echoes Based on Millimeter-wave Cloud Radar Measurements显示文摘Millimeter-wave cloud radar(MMCR)provides the capability of detecting the features of micro particles inside clouds and describing the internal microphysical structure of the clouds.Therefore,MMCR has been widely applied in cloud observations.However,due to the influence of non-meteorological factors such as insects,the cloud observations are often contaminated by non-meteorological echoes in the clear air,known as clear-air echoes.It is of great significance to automatically identify the clear-air echoes in order to extract effective meteorological information from the complex weather background.The characteristics of clear-air echoes are studied here by combining data from four devices:an MMCR,a laser-ceilometer,an L-band radiosonde,and an all-sky camera.In addition,a new algorithm,which includes feature extraction,feature selection,and classification,is proposed to achieve the automatic identification of clear-air echoes.The results show that the recognition algorithm is fairly satisfied in both simple and complex weather conditions.The recognition accuracy can reach up to 95.86%for the simple cases when cloud echoes and clear-air echoes are separate,and 88.38%for the complicated cases when low cloud echoes and clear-air echoes are mixed. | Ling YANG Yun WANG Zhongke WANG Qian YANG Xingang FAN Fa TAO Xiaoqiong ZHEN Zhipeng YANG | 2020 | Advances in Atmospheric Sciences2020，37，8： | 2 |
| 10 | Porous covalent organic frameworks-improved solid phase microextraction ambient mass spectrometry for ultrasensitive analysis of tetrabromobisphenol-A analogs显示文摘Owing to frequent environmental monitoring of tetrabromobisphenol-A(TBBPA)analogs and their potential ecotoxicological effects on organisms,analysis of trace levels of TBBPA analogs with more non-polar and less water-soluble characteristics is of great significance for studying their environmental behaviors and toxic effects.Herein,a fast and sensitive technique is developed for directly detecting aqueous TBBPA analogs,including TBBPA mono(allyl ether)(TBBPA-MAE),TBBPA mono(2,3-dibromopropyl ether)(TBBPAMDBPE),TBBPA mono(2-hydroxyethyl ether)(TBBPA-MHEE)and TBBPA mono(glycidyl ether)(TBBPAMGE),by combining solid phase microextraction(SPME)based on porous covalent organic frameworks(Porous-COFs)with constant flow desorption ionization-mass spectrometry(CFDI-MS).As chromatographic separation is replaced by constant flow desorption,each sample can be analyzed within 7 min.The hierarchical porous structures(microporous,mesoporous and macroporous)of COFs lead to the enhanced mass transfer and the easier accessibility of active sites to TBBPA analogs,so that the extraction efficiency is 2.3-3.6 times higher than pure microporous COFs,and far superior to commercial coatings.The detection limit and quantification limit of this method are 0.1-1 and 0.4-3.2 ng/L,respectively.Ultratrace levels of TBBPA analogs from 5.0 ng/L to 66 ng/L have been successfully detected in river and sea water samples,showing great potential for subsequent studies of their environmental behaviors and toxicological effects. | Wei Gao Min Li Yun Fa Zongshan Zhao Yaqi Cai Xiangfeng Liang Yongliang Yu Guibin Jiang | 2022 | Chinese Chemical Letters2022，33，8： | 1 |
