RESUMEN

Objective@#To understand sleep behavior among primary and middle school students and its impact on overweight and obesity changes, to provide evidence for developing obesity prevention and controlling strategies in children and adolescents.@*Methods@#Primary and middle school students from three cities in Zhejiang Province who participated in questionnaire surveys and physical measurements in both 2017 and 2019 were selected. A follow up dataset of 605 students was developed and the relationship between sleep duration and body mass index was analyzed.@*Results@#From 2017 to 2019, BMI Z scores for male and female participants increased by 0.24 and 0.13, respectively. BMI Z scores increased by 0.29 in students of 9-12 years old and increased by 0.11 and 0.25 in urban and rural students, respectively ( P <0.05). The prevalence of insufficient sleep duration increased from 37.0 % to 41.8% simultaneously ( χ 2=3.68, P =0.06). After adjusting for confounding factors, the BMI Z score of students with insufficient sleep was 0.20 higher than those with sufficient sleep duration ( P <0.01). Compared with participants who had sufficient sleep duration from 2017 to 2019, participants whose sleep duration changed from sufficient to insufficient, and those who always had insufficient sleep duration increased by 0.23, respectively ( P <0.05).@*Conclusion@#Insufficient sleep duration is a risk factor for obesity. Shortened sleep duration is related to weight gain, and maintaining sufficient sleep duration may reduce the risk of obesity in children and adolescents.

RESUMEN

Objective @#To understand the prevalence of overweight and obesity, and the influencing factors among students aged 7-22 years in Zhejiang Province. @*Methods @#Stratified random cluster sampling was used to randomly select students aged 7-22 years in 11 prefectures of Zhejiang Province in 2019. Height and weight were measured. The general information, dietary habits and living habits of students were collected using the Student Health Status and Influencing Factors Questionnaire. The multivariate logistic regression model was used to analyze the influencing factors of overweight and obesity. @*Results @#A total of 33 800 respondents were included, 7 685 (22.74%) were overweight/obese, 4 729 ( 13.99% ) were overweight, and 2 956 ( 8.75% ) were obese. The multivariate logistic regression analysis suggested that boys ( OR=2.059, 95%CI:1.949-2.175), not living on campus( OR=1.306, 95%CI: 1.214-1.405), history of alcohol consumption ( OR=1.158, 95%CI:1.083-1.238 ), average daily consumption of sugar-sweetened beverages in the past week ( less than once, OR=1.214, 95%CI: 1.103-1.336; once and more, OR=1.431, 95%CI: 1.259-1.626 ), average daily consumption of fries in the past week ( less than once, OR=1.171, 95%CI: 1.065-1.288; once and more, OR=1.266, 95%CI: 1.102-1.454 ), and average daily consumption of sweets in the past week (less than once, OR=0.727, 95%CI: 0.658-0.802; once and more, OR=0.504, 95%CI: 0.444-0.572) were associated with overweight and obesity in students. @*Conclusion @#The prevalence rates of overweight and obesity among students aged 7-22 years in Zhejiang Province are 13.99% and 8.75%, respectively, which are associated with boys, not living on campus, and consumption of sugar-sweetened beverages, fries, sweets and alcohol.

RESUMEN

This study aimed to evaluate the therapeutic effect of IR-61, a novel mitochondrial heptamethine cyanine dye with antioxidant effects, on diabetes mellitus-induced erectile dysfunction (DMED). Eight-week-old male Sprague-Dawley rats were intraperitoneally injected with streptozotocin (STZ) to induce type 1 diabetes. Eight weeks after STZ injection, all rats were divided into three groups: the control group, DM group, and DM + IR-61 group. In the DM + IR-61 group, the rats were administered IR-61 (1.6 mg kg

RESUMEN

Objective@#To explore the influencing factors for the primary and secondary school students with abnormal angle of trunk rotation for the prevention.@*Methods@#The students of Grade Four to Nine in Jiashan County of Zhejiang Province were selected by cluster sampling method. A self-designed questionnaire was used to collect social demographic data, diet behaviors, physical activities, reading and writing habits. The angle of trunk rotation was measured by scoliometer. Logistic regression model was used to investigate the influencing factors for abnormal angle of trunk rotation. @*Results@#This study included 2 942 schoolchildren, with 1 582 ( 53.78% ) boys and 1 360 ( 46.23% ) girls. The incidence rate of abnormal angle of trunk rotation was 7.82%. The incidence rate of abnormal angle of trunk rotation in girls was 10.74%, which was higher than 5.31% in boys ( P<0.05 ). Grade ( OR=1.485, 95%CI: 1.058-2.085 ), gender ( OR=2.084, 95%CI: 1.536-2.828 ), frequency of eating fresh vegetables in the past week ( OR=0.749, 95%CI: 0.633-0.887 ) and watching electronic screen in the dark ( OR=1.188, 95%CI: 1.002-1.408 ) were the influencing factors for abnormal angle of trunk rotation in primary and secondary school students. Grade ( OR=2.664, 95%CI: 1.481-4.791 ) and watching electronic screen in the dark ( OR=1.325, 95%CI: 1.030-1.704 ) were influencing factors for abnormal angle of trunk rotation in boys. Frequency of eating fresh vegetables in the past week ( OR=0.714, 95%CI: 0.574-0.887 ) and uncorrected eyesight less than 5.0 ( OR=1.795, 95%CI: 1.164-2.767 ) were influencing factors for abnormal angle of trunk rotation in girls. @*Conclusion@#The abnormal angle of trunk rotation in primary and secondary school students is related to gender, grade, reading and writing behaviors as well as diets; and the influencing factors are different in male and female students.

RESUMEN

Objective@#To investigate the prevalence and influencing factors of adolescent depression symptoms in Zhejiang, so as to provide reference for improving their mental health. @*Methods@#The middle school and university students in 11 cities of Zhejiang Province were selected by stratified cluster random sampling method. The depression symptoms of the adolescents were assessed by Center for Epidemiological Survey-Depression Scale ( CES-D ) and the influencing factors were analyzed by multivariate logistic regression model.@*Results@# A total of 25 855 students were investigated, and 25 614 ( 99.07% ) valid questionnaires were collected. The detection rate of depressive symptoms was 26.86%(6 879 cases). The detection rate of depressive symptoms in girls was 29.75%, which was higher than 24.12% in boys ( P<0.05). The detection rate of depressive symptoms in high school students was 31.74%, the highest compared with other grades. The multivariate regression analysis showed that female students ( OR=1.690, 95%CI: 1.592-1.794 ), resident students ( OR=1.071, 95%CI: 1.010-1.137 ) , internet addiction ( OR=2.948, 95%CI: 2.527-3.439 ) , attempt smoking ( OR=1.516, 95%CI: 1.359-1.690 ), drinking ( OR=1.624, 95%CI: 1.525-1.729 ), bullied in the past 30 days ( OR=3.143, 95%CI: 2.938-3.363 and having serious injuries within a year ( OR=1.369, 95%CI: 1.263-1.543 ) were associated with adolescents who had depressive symptoms.@*Conclusions@#The detection rate of depressive symptoms is relative 26.86% among adolescents of Zhejiang Province. The students who are female, live on campus, have internet addiction, have been bullied or seriously injured, smoke and drink are more likely to have depressive symptoms.
