Social Isolation Has Minimal Impact on Children’s Sleep and Eating Behaviours

Reading Time: 2 minutes

Social relationships play a crucial role in mental and physical well-being, impacting both adults and adolescents. The recent study investigates the influence of social isolation on sleep and eating behaviours in young children during the Covid pandemic. Researchers from the University of Fribourg and the University Hospital Zurich aimed to determine whether the extent of social contact during the pandemic significantly affected children’s sleep quality and eating patterns.

This observational study involved 439 carers of 562 children aged 0–6 years who provided information on their children’s sleep and eating behaviours, as well as their level of social contact during the early months of the pandemic in 2020. The data collected included the children’s sleep duration, sleep latency, bedtimes, and nighttime awakenings, along with their consumption of meals, sweet and salty snacks, fruits, and vegetables.

The findings were published in the journal Sleep.

The study found that social isolation had minimal impact on the sleep and eating behaviours of infants (0–3 years) and preschool children (3–6 years). 

The study found no significant relationship between the extent of social contact and changes in sleep duration, sleep latency, bedtimes, or nighttime awakenings in both infants and preschool children.

For infants, changes in meal size and the consumption of snacks, fruits, and vegetables were not significantly linked to their social contact levels. However, a trend was observed in preschool children, suggesting that quarantine status might be associated with increased meal size, although this trend did not reach statistical significance after adjustments.

These findings are noteworthy as they challenge the expectation that social isolation would significantly disrupt children’s sleep and eating behaviours, similar to effects observed in adults. The negligible associations in young children suggest that other factors may play a more prominent role in shaping these behaviours.

The results indicated that the changes in sleep patterns observed during the pandemic were not strongly linked to social isolation. While sleep duration and quality did see some shifts, these were not directly tied to the levels of social contact. This contrasts with adults, where social isolation is well-documented to adversely affect sleep quality, often leading to shorter sleep durations and more frequent nighttime awakenings.

Similarly, the study found that the changes in eating behaviour, such as meal size and the consumption of snacks, fruits, and vegetables, were not significantly associated with social isolation in infants. Preschool children in quarantine did show a tendency towards increased meal sizes, yet this finding was not statistically robust.

The study’s observational nature and reliance on caregiver-reported data introduce potential biases, such as recall bias, which could affect the accuracy of reported behaviours. Additionally, the study did not account for the timing of meals or other aspects of dietary habits that could influence sleep patterns.

Further research is needed to explore the potential influence of other factors, such as psychological stress, physical activity, and the broader family context, on children’s sleep and eating behaviours. Understanding these dynamics is particularly important given the rising rates of childhood obesity and sleep problems in recent years.
