Insights
Childhood overnutrition is linked to sleep-disordered breathing (SDB). Severely obese children and those with thicker skinfolds showed a higher prevalence of SDB.
Area of Science:
- Pediatrics
- Public Health
- Sleep Medicine
Background:
- Childhood overnutrition is a global health concern.
- Overnutrition is associated with various diseases, including sleep-disordered breathing (SDB).
- SDB is an emerging health issue in children.
Purpose of the Study:
- To investigate the association between nutritional status and SDB in schoolchildren.
- To determine if anthropometric measurements correlate with SDB prevalence.
Main Methods:
- A cross-sectional study involving 127 schoolchildren in Valdivia, Chile.
- Nutritional status assessed via anthropometric measurements.
- SDB presence determined using the Pediatric Sleep Questionnaire (PSQ).
Main Results:
- High prevalence of overnutrition (71.7%) and obesity (39.4%) was observed.
- SDB prevalence was 32.3% among the schoolchildren.
- Children with SDB had significantly higher biceps and triceps skinfold thickness.
Conclusions:
- A significant association exists between overnutrition and SDB in schoolchildren.
- Greater biceps and triceps skinfold thickness are linked to the presence of SDB.
- Findings highlight the importance of nutritional status assessment in pediatric SDB.
Introduction:
Overnutrition in childhood constitutes a global epidemic and has been associated with multiple di seases and complications. Among them, sleep-disordered breathing (SDB) stands out, a spectrum of diseases that have emerged as a relevant health problem.
Objective:
To evaluate the association between nutritional status and SDB in schoolchildren.
Subjects And Method:
Cross-sectional analyti cal study of 127 schoolchildren randomly selected from five public schools in Valdivia, Chile. After the informed assent and informed consent process of the child and parents/guardian respectively, the students were incorporated into the study. Anthropometric measurements were performed and the presence of SDB was determined through the Pediatric Sleep Questionnaire (PSQ). For the data analysis, the t-test and %2 test were used to determine the association of variables with SDB. Re sults: There was a high prevalence of overnutrition (71.7%) and obesity reached 39.4%. Regarding the prevalence of SDB, it was 32.3%. There was a higher proportion of children with SDB in severely obese schoolchildren (56.3%), as well as, a significantly higher mean of biceps and triceps skinfold thickness in children with SDB (14.6 mm ± 7.3 vs. 12.0 mm ± 6.6, p = 0.002, and 19.8 ± 6.7 mm vs. 16.2 mm ± 6.0, p = 0.04, respectively).
Conclusions:
There is high prevalence of overnutrition and SDB. Out of the anthropometric measurements, the presence of SDB was associated with greater thickness of the biceps and triceps skinfolds.
