Our study investigated parenting and children’s emotional and lifestyle responses to the COVID-19 epidemic in China. More than 80% of parents or children frequently communicated about the COVID-19 epidemic, and more than 10% of parents had a more irritable attitude and reported worse parent-child closeness during the epidemic. Around 10% of children were at a risk of clinically significant emotional problems, and about half of the children had stress symptoms during the epidemic. Our study also found a high prevalence (30%~80%) of unhealthy lifestyles both at normal times (before the epidemic) and during the epidemic, with a higher prevalence during the epidemic. Differing emotional and lifestyle responses were observed among children from socially disadvantaged families, making them more vulnerable to the epidemic. Children whose parents frequently communicated about COVID-19, or were more irritable, or who experienced worse closeness with their parents were more likely to have internalized emotional problems, stress symptoms, and worse lifestyles during the COVID-19 epidemic.
Our survey found a high prevalence of inactive children even during normal times (before the epidemic), concurring with the findings of earlier studies. In a pooled analysis of 298 population-based surveys, the overall prevalence of insufficient physical activity was 84.3% among Chinese adolescents aged 11–17 years in 2016 [23], and in another study with a sample of 131,859 Chinese students aged 7–19 years, about 35% of children did not meet the recommended screen viewing time [11]. Moreover, we found that screen viewing time and physical activity levels worsened during the epidemic (compared to normal times) in both Wuhan and Shanghai. This finding highlights potential challenges to China achieving the WHO target of a 15% relative reduction in insufficient physical activity for children by 2030 due to the COVID-19 epidemic [24]. Furthermore, lesser hours of sleep and worse sleep quality were observed among children during the epidemic; the prevalence of children and adolescents sleeping less than 8 hours increased from 34% normally to 54% during the epidemic. Children’s sleep, physical activity and screen time are often found interacted, where more screen time and less time outdoors are known to be adversely associated with sleep outcomes [25,26]. Therefore, a multi-tiered approach involving the society, school and family is required to promote better mental and physical health for children and adolescents during the epidemic and similar public health emergencies [27].
In our study, parenting characteristics were observed to play an important role in children’s emotional and lifestyle responses to the COVID-19 epidemic. Frequent communication about the epidemic between parents and children, having irritable parents and worse parent-child closeness were observed to be associated with an increased odd of emotional problems and unhealthy lifestyles among children. There was an increased spread of misinformation and rumors about the epidemic, and excessive exposure to negative information may increase fears and anxieties for both parents and children. Our findings concur with the view that parents who lack appropriate skill or guidance to help themselves and their children face greater adversity during a public health emergency. A previous study also found similar results for adults; adults who spent more time focusing on the epidemic were more likely to develop anxiety symptoms [28]. Family systems theory suggests that children and adolescents in families are strongly influenced by marital problems and poor parenting [15]. If parents have psychological distress, they are likely to transmit their distress during interactions with their children and create a negative atmosphere which could lead to persistent or delayed-onset distress symptoms [27]. Many studies have illustrated that mental health is worst among children whose caregivers have experienced negative mental health outcomes from disasters [29–31]. Therefore, health education should be provided to parents to improve their knowledge about the epidemic and reinforce good parenting skills to improve the quality of communication between parents and children. Parents should be educated with scientific information to generate awareness about the importance of healthy lifestyles such as ongoing physical activity and reduced screen time especially during the epidemic.
Our study also shows that children from socially-disadvantaged families have worse parenting, emotional and lifestyle responses to the epidemic than those from advantaged families. Parents who are socially disadvantaged (in terms of education, employment or economic status) may have lower health literacy and awareness about their own or their child’s health risks; and they may not be able to recognize negative changes in their child’s emotional health and lifestyles and provide timely support to their children [32,33]. In addition, socially disadvantaged parents may also be more likely to suffer psychological stresses and other health problems themselves, especially during the epidemic [34,35]. A previous study observed that parents who had not returned to work due to the epidemic were more likely to experience higher stress and anxiety regarding job continuity and financial security [25]. Highly stressed parents may in turn be more irritable towards their children and more likely to express negative emotions in their child’s presence, which may lead to more frequent emotional and lifestyle problems among their children. Therefore, it is vital to deliver interventions targeting parents from such disadvantaged groups, providing them appropriate health education and psychological services to decrease the disproportionate emotional and behavioral responses their children face during the COVID-19 epidemic.
Our study had a few limitations. First, there may be a degree of recall bias as we aimed to investigate changes in children’s lifestyle outcomes during the COVID-19 epidemic compared to the previous winter break (based on parent recall). Second, most respondents were parents instead of the children themselves, which may lead to reporting bias. Third, our results may be affected by selection bias from the use of an online survey methodology. We sent multiple invitations to respondents who did not initially respond to our survey to mitigate this bias. Finally, this was a cross-sectional study, and there is a need for follow-up studies on the emotional and lifestyle changes of children and adolescents during public health emergencies such as the COVID-19 epidemic to validate our findings.
