Brief Summary

The aim was to evaluate the relationship between dietary AGE intake and sleep quality and some nutrient intake of healthy children aged 3-5 years registered in various nurseries in Ankara. The main question that the study aimed to answer is: Does dietary AGE intake affect sleep quality in preschool children? 304 children (140 girls, 164 boys) were included in the study. According to the SDSC scale, 67.5% of the participants were at risk of sleep disorders. The dAGE intake of children at risk of sleep disorders was significantly higher compared to children with normal sleep status.

Outcome Measures

Primary Outcomes (2)

• sleep quality

  To categorize sleep disturbances in children, the psychometric properties were evaluated using the 27-item Likert-type rating scale, the SDSC. The total score is 26 - 130. As the score increases, sleep quality deteriorates.

  Baseline

• dAGE intake

  Dietary AGE measurements were calculated based on the database of Uribarri et al. A 24-hour retrospective food consumption record was obtained from the children.
