ABSTRACT
Objective@#To understand physical development of children aged 7 to 12 in the oroqen autonomous banner experimental primary school in the oroqen settlement area from 2013 to 2018, and to provide scientific basis for their physical fitness and health.@*Methods@#According to the standards of "National Student Physical Health Standards (2014 Revised Edition)" and the standards of "Overweight and Obesity Screening for School age Children and Adolescents" issued by the National Health and Family Planning Commission in 2018, the Oroqen Autonomous Banner Experimental Primary School was 7-12 years old. The average value and growth rate of children s height, weight and BMI in the past 6 years.@*Results@#From 2013 to 2018, the height and weight of boys and girls aged 7 to 12 showed an increasing trend, with height growth values of boys were 1.8,1.7,1.9,2.6,5.7,5.9 cm,girls were 2.8,4.5,1.9,1.8,3.6,2.9 cm.And the weight groups values of boys were 2.2,2.5,5.1,6.3,6.4,7.2 kg,girls were 2.4,3.6,3.1,1.3,4.6,3.0 kg. The growth rate of girls aged 7 to 8 was higher than that of boys, and the growth rate of boys aged 9 to 12 was higher than that of girls. With the increase of age, the average BMI of boys and girls aged 7 to 12 showed an upward trend, and the BMI of boys of the same age was always higher than that of girls. Among them, the average BMI of boys aged 7 to 12 in 2018 exceeded the critical value of overweight BMI.@*Conclusion@#The physical shape of children aged 7-12 years increases with age, but the development tends to be overweight and obese, which is related to the natural environment of life, lifestyle, and reduction in physical activity.
ABSTRACT
Objective:To investigate the current situation of students' academic procrastination behavior in medical colleges and universities and its influencing factors, and to put forward suggestions to reduce the academic procrastination of medical students.Methods:A total of 1 327 undergraduate students from three medical colleges and universities in Heilongjiang Province were randomly selected to receive questionnaire investigation on life satisfaction, anxiety, and academic procrastination. SPSS 23.0 was used for data analysis.Results:①The total procrastination scores of medical students were (35.00±8.92) points. ②There were statistical differences in the academic procrastination of medical students with different genders, whether the only children, the reasons for choosing the major, and the level of achievement ( P < 0.05). There was no statistical difference in academic procrastination among medical students of different ages and grades ( P > 0.05). ③Medical students' procrastination was positively correlated with their anxiety level ( r = 0.102, P < 0.01), and negatively correlated with life satisfaction ( r = -0.117, P < 0.01). ④Regression analysis showed that the following six predictive variables including the level of achievement, gender, life satisfaction, anxiety, reasons for choosing the major, and whether the only children could effectively explain the variance of 14.2% academic procrastination of medical students. Conclusion:The overall degree of academic procrastination of medical students is higher than that of non-medical students. And the students' achievement level, gender, life satisfaction, anxiety, the reasons for choosing this major and whether the only child are the influencing factors of academic procrastination.

ABSTRACT
Objective To examine the current situation of the career plateau among anesthesiologists and analyze the impact of occupational stressors on it. Methods A questionnaire survey was conducted on the anesthesiologists. A total of 300 questionnaires were distributed and 278 questionnaires were effectively collected. Statistical analysis using SPSS 19.0 was performed to assess the status quo of career plateau among anesthesiologists. Pearson correlation analysis and stepwise regression analysis were used to analyze the influence of occupational stressors on career plateau . Results The average value of occupational stressors among anesthesiologists was (3.22±0.55), and the average value of career plateau was (3.90±0.70). Occupational interest in the occupational stressors of anesthesiologists is negatively correlated with the occupational plateau (r=-0.552, P<0.01), and career development is negatively correlated with occupational plateau (r=-0.541, P<0.01) as well. Both occupational interest and career development show a negative predictive effect on the career plateau (β=-0.359, P<0.01 andβ=-0.334, P<0.01, respectively). Conclusion Career plateau among anesthesiologists is at a medium-to-high level. Occupational interest and occupational development in occupational stressors have a negative predictive effect on occupational plateaus, so hospital managers should pay attention to them.
ABSTRACT
Objective To explore the impact of work-family conflict on job satisfaction and turnover intention of anesthesiologists in Heilongjiang Province.Methods Questionnaire survey was used for data collection.Descriptive statistics,Pearson correlation analysis and multivariate linear hierarchy regression analysis were performed to analyze the impact of work-family conflict on job satisfaction and turnover intention of anesthesiologists.Results The average value of work-family conflict among anesthesiologists was (2.99 ± 0.57).The finding indicated that work-family conflict of anesthesiologists had a significant negative effect on job satisfaction (β=-0.248,P＜0.01) and a positive effect on turnover intention (β=0.329,P＜0.01).Conclusion Anesthesiologists' work-family conflict is above the middle level in Heilongjiang Province.The work-family conflict of anesthesiologists can reduce job satisfaction and increase turnover intention.
