Abstract
Background
Individuals who visit hospitals with neurodevelopmental disorders have recently increased.
To locate the cause for this increase, various factors, such as environmental and
genetic ones, are being investigated. The objective of this study is to analyze the
developmental delay in children and their background.
Methods
The participants were children who underwent the checkup for 18-month-old children
in Togane city, Japan, from 2011 to 2021; 4,145 children—2,147 boys and 1,998 girls
with a mean age of 18.8 months—were included. To examine the tendency over time and
the background, we used the questionnaire about development and lifestyle reported
by parents.
Results
The number of children who did not produce pointing gestures or respond to their names
and low-volume sounds tended to increase over the survey period (p = 0.0125, p = 0.0435,
p = 0.0275). Next, we examined the relationship between pointing gestures and lifestyle
and found that there was a relationship between attending a nursery school and bedtime
and pointing gestures.
Conclusion
A slow developmental trend over the last decade has been observed among children.
The background was related to attending a nursery school and bedtime, suggesting that
interaction with others and sleep are important for the development of children.
