ABSTRACT
Objective:
To explore the
obesity-related factors among primary and middle
school students in Hangzhou.
Methods:
A stratified random
cluster sampling cross-sectional study was conducted using Hangzhou city's 2016-2020 annual
school health survey data. Finally, 9 213 primary and
secondary school students with complete data were selected as the
research objects. The standard of
Overweight and
Obesity Screening for
School-age
Children and
Adolescents (WS/T 586-2018) was used to verify
students'
obesity. SPSS 25.0
software was applied to conduct
statistical analysis on the related factors of
obesity.
Results:
The overall
obesity detection rate among primary and middle
school students in Hangzhou was 8.52%. The results of
logistic regression analysis showed that
inadequate sleep (OR=6.507, 95%CI 2.371-17.861, P<0.001), 3- hours (OR=5.666, 95%CI 2.164-14.835, P<0.001) and ≥4 hours (OR=7.530, 95%CI 2.804-20.221, P<0.001) of watching video every day in the past week, being beaten and scolded by
parents in the past week (OR=1.627, 95%CI 1.161-2.280, P=0.005),
parents often reduce
students'
exercise time in order to
let students have more
time to study in the past week (OR=3.310, 95%CI 1.243-8.819, P=0.017), age 16-18 years old (OR=0.137, 95%CI 0.050-0.374, P<0.001), often suffering from campus
violence in the past week (OR=0.332, 95%CI 0.141-0.783, P=0.012), 1 hour of watching video every day in the past week (OR=0.023, 95%CI 0.006-0.083, P<0.001), sometimes having
breakfast (OR=0.151, 95%CI 0.058-0.397, P<0.001) and
eating breakfast every day (OR=0.020, 95%CI 0.005-0.065, P<0.001) in the past week,
eating vegetables and
fruits sometimes (OR=0.015, 95%CI 0.010-0.023, P<0.001) and every day (OR=0.020, 95%CI 0.008-0.053, P<0.001) in the past week,
eating sweet
food sometimes (OR=0.089, 95%CI 0.035-0.227, P<0.001) and every day (OR=2.568, 95%CI 1.632-4.041, P<0.001) in the past week,
eating fried
food sometimes (OR=0.274, 95%CI 0.094-0.800, P=0.018) in the past week, and having three
physical education classes every week (OR=0.156, 95%CI 0.057-0.423, P<0.001) were the main related factors affecting the occurrence of
obesity in primary and
secondary school students.
Conclusions:
With the higher
obesity prevalence among primary and middle
school students in Hangzhou,
parents and teachers should strengthen
health education for primary and middle
school students, help
children develop scientific
eating behavior, develop positive and healthy living
habits of
children, and effectively prevent
overweight/
obesity in primary and middle
school students.
