ABSTRACT
Background: The outbreak of COVID-19 had a huge impact on daily life. It greatly reduced our physical activity (PA) and caused an increase in negative emotions. The emotions of different ages and sexes were impacted during the pandemic but the most severely influenced were adolescents. Therefore, the study's main purpose was to explore the influence of age and gender on adolescent physical activity and emotions during the pandemic. Methods: The subjects of the present study were 14,045 adolescents aged 10-18 years from the Yan'an Shaanxi province. The International Physical Activity Questionnaire Short Form (IPAQ-SF) was used to investigate the PA and Profile of Mood States (POMS) was used to investigate adolescents' mood states. Results: we found that girls and boys have significant differences in total PA and moderate PA (p < 0.01). The adolescents' PA levels of different ages had significant differences (p < 0.01). Meanwhile, boys had higher negative emotion scores (anger, fatigue, depression, confusion) than girls. Girls, in contrast, had higher positive emotion scores (self-esteem, vigor) (p < 0.01). With increasing age, the increase in emotional states seems to diminish (p < 0.01). Conclusions: Results show long-term social isolation causes reduced PA and increased negative mood states. Girls' PA was higher than boys, and boys had higher levels of mood disturbances. PA and levels of mood disturbances were significantly associated with age from 10 to 18 years old. This research study aimed to help the correlation department understand the relationship between PA and mood states of adolescents of different ages and sexes during COVID-19. Providing health promotion and preventative advice for different sex and age groups has expanded globally.
ABSTRACT
The COVID-19 epidemic adversely affects the lifestyle of people. This study aimed to examine the impacts of social isolation on physical activity (PA) levels and mood states of children and adolescents and to explore the correlation between them during the COVID-19 epidemic. A total of 9979 children and adolescents (11.63 ± 1.23 years old) from Yan'an, China volunteered to participate in this study and completed online questionnaires. PA and mood states were measured by International Physical Activity Questionnaire Short Form (IPAQ-SF) and Profile of Mood States (POMS), respectively. The results showed that the mean of students' moderate-to-vigorous PA (MVPA) was 23.19 min per day. The total mood disturbance in the moderate and high-level PA groups were significantly lower than those in the low-level PA group (p < 0.05). Additionally, boys and girls had significant differences in PA levels (p < 0.01), and the PA levels of students in different grades were also significantly different (p < 0.01). Meanwhile, boys' mood states were worse than girls'. The Grade 4 in primary schools had the worst mood states while Grade 5 had the best mood states. The results suggested that the MVPA of students has dropped badly, compared with the results of previous studies investigated in normal times. In addition, the PA level had a significantly positive impact on the mood states of children and adolescents during the COVID-19 epidemic. Sex and grades were factors which affected the PA levels and mood states. This study can help policymakers and healthcare professionals understand PA and mood states of Chinese children and adolescents during the epidemic. We should pay attention to the changes in PA levels and mood states of children and adolescents.
