Effect of Sleeping Disorders on the Growth Parameters of Lebanese Children.

BACKGROUND: Sleep is a vital physiological function for the maintenance of health and quality of life by ensuring body rest and restoring its energy levels. Remarkably, some children have sleep disordered breathing (SDB) that can disturb their normal sleep and affect the quality of their lives.

OBJECTIVE: The aim of this study was to assess the correlation between SDB and growth impairments and wether the growth parameters vary among genders.

METHODS: This study was conducted in two steps: 1500 questionnaires were distributed to children aged 3 to 12 years. The questionnaire covered personal information, medical history, and the Pediatric Sleep Questionnaire. The latter was used to evaluate the incidence of sleep-disordered breathing and was completed by parents of the involved children. Growth assessment was then determined for the population to find the correlation between sleep disorders and growth impairments.

RESULTS: A total of 931 completed questionnaires were returned (70.7% response rate). Among the respondents, 56.3% were females whereas 43.3% were males. The mean age was 8 years. The result showed that 16.11% of children were at high risk of sleep-disordered breathing. A significant effect of SDB syndrome on growth parameters (weight-for-age parameter z-score and BMI for age z-score) was observed among males. Concerning the weight for age z-score, a significant difference was found between the means of control and SDB individuals (P = 0.0302). In male groups, the difference was significant (P=0.043), while non-significant difference was found in female groups (P = 0.69).

CONCLUSION: This study highlights a significant effect of SDB on growth parameters among males aged between 3 and 12 years.
