ABSTRACT
Objective@#To investigate the use of e-cigarette and analyze its influencing factors among high school students in Wuhan City, so as to provide insights into developing control measures for adolescents.@*Methods@#From September to November 2019, high school students in Wuhan City were selected by the multi-stage stratified cluster random sampling method, and basic information, e-cigarette use and second-hand smoke exposure were collected through questionnaire surveys. Proportions of e-cigarette current use and attempt to use were analyzed, and factors affecting the current use of e-cigarettes were identified using a multivariable logistic regression model.@*Results@#Totally 5 700 questionnaires were allocated, and 5 602 valid questionnaires were recovered, with an effective rate of 98.28%. The respondents included 2 925 males (52.21%) and 2 677 females (47.79%); 4 033 high school students (71.99%) and 1 569 vocational high school students (28.01%). The proportion of attempt to use e-cigarettes was 9.23%, and the proportion of current e-cigarette use was 2.03%. Multivariable logistic regression analysis identified male (OR=2.112, 95%CI: 1.285-3.471), vocational high school (OR=1.967, 95%CI: 1.214-3.186), private high school (OR=9.684, 95%CI: 5.648-16.605), family second-hand smoke exposure (OR=3.064, 95%CI: 1.741-5.392), second-hand smoke exposure in public places (OR=4.402, 95%CI: 1.687-11.484) and having close friends who were smokers (OR=6.432, 95%CI: 3.219-12.852) as factors affecting current e-cigarette use among high school students.@*Conclusions@#The proportion of current e-cigarette use among high school students in Wuhan City was 2.03%. Male, vocational high school, private high school, second-hand smoke exposure and having close friends who were smokers may be promoting factors for e-cigarette use.
ABSTRACT
Objective@#To understand the level of health behaviors related to prevention and control of Corona Virus Disease 2019, COVID-19 among primary school students in Wuhan during the epidemic, and to provide a basis for further targeted health education and promotion.@*Methods@#Stratified random sampling was used to select 12 primary schools in Wuhan. Relying on the "questionnaire star", the head teacher of the selected school sent the questionnaire link to students through the QQ or WeChat group, and all students participated in the survey voluntarily.@*Results@#A total of 8 569 valid questionnaires were collected. The rate of prevention and control of COVID-19 among primary school students in Wuhan was 39.3%. Among them, wearing masks, hand hygiene and other healthy behavior accounted for 53.4%, 42.0% and 75.2%, respectively. Multivariate logistic regression analysis showed that girl, grade 3-4 and 5-6, higher maternal education (>graduate degree) were more likely to have overall health behaviors in the prevention and control of COVID-19, and the OR values were 1.13(95%CI=1.04-1.24), 1.18(95%CI=1.06-1.31) 1.58(95%CI=1.41-1.75) and 1.62(95%CI=1.00-2.62)(P<0.05), respectively. Compared with fathers whose occupations were state agencies, managers of enterprises and institutions, students whose fathers’ occupations were professional technicians and ordinary employees were less likely to have level of overall health behaviors in the prevention and control of COVID-19, and the OR values were 0.78(95%CI=0.61-0.99) and 0.72(95%CI=0.58-0.90)(P<0.05), respectively.@*Conclusion@#The level of health behaviors of primary school children in Wuhan against COVID-19 was not high and targeted health education and promotion should be provided.
ABSTRACT
ABSTRACT Objectives: Our study aimed to investigate the associations of glucose tolerance status with insulin-like growth factor-I (IGF-I) and other clinical laboratory parameters of acromegalic patients before and after the patients underwent transsphenoidal adenomectomy (TSA) by conducting a single-center, retrospective study. Subjects and methods: A total of 218 patients with acromegaly who had undergone TSA as the first treatment were retrospectively analyzed. Serum IGF-I, growth hormone (GH) and glucose levels were measured before and after surgery. Results: The follow-up levels for random GH, GH nadir, and the percentage of the upper limit of normal IGF-I (%ULN IGF-I) were decreased significantly. The percentages of normal (39.0%), early carbohydrate metabolism disorders (33.0%) and diabetes mellitus (28.0%) changed to 70.2%, 16.5% and 13.3%, respectively, after TSA. %ULN IGF-I at baseline was higher in the diabetes mellitus (DM) group than in the normal glucose tolerance group and impaired glucose tolerance (IGT) /impaired fasting glucose (IFG) groups before TSA, and the DM group exhibited a greater reduction in %ULN IGF-I value after surgery. The follow-up %ULN IGF-I value after surgery was significantly lower in the improved group, and Pearson's correlation analysis revealed that the reductions in %ULN IGF-I corresponded with the reductions in glucose level. Conclusion: This study examined the largest reported sample with complete preoperative and follow-up data. The results suggest that the age- and sex-adjusted IGF-I level, which reflects altered glucose metabolism, and the change of it are associated with improved glucose tolerance in acromegalic patients both before and after TSA.
