Insights

Pediatric obstructive sleep apnea negatively impacts child growth. Higher respiratory disturbance and lower oxygen saturation during sleep are linked to reduced height z-scores in children.

Area of Science:

  • Pediatric Pulmonology
  • Sleep Medicine
  • Pediatric Endocrinology

Background:

  • Pediatric obstructive sleep apnea (POSA) is common and linked to health issues.
  • Growth disturbance is a debated complication of POSA.

Purpose of the Study:

  • To investigate the relationship between POSA severity and longitudinal growth in children.
  • To determine if sleep-disordered breathing affects height in pediatric patients.

Main Methods:

  • 745 children with POSA underwent polysomnography.
  • Height, weight, and BMI were converted to z-scores.
  • Multiple linear regression analyzed correlations between POSA metrics and height z-scores.

Main Results:

  • Higher respiratory disturbance index and lower oxygen saturation correlated with smaller height z-scores.
  • POSA severity metrics (AHI, RDI, OAI, HI) negatively correlated with height z-scores.
  • Mean oxygen saturation positively correlated with height z-scores.

Conclusions:

  • POSA negatively affects longitudinal growth in children.
  • Sleep-disordered breathing and oxygen desaturation are associated with reduced height.
  • Findings suggest POSA is a risk factor for growth impairment.

Sleep Apnea01:21

Sleep Apnea

Sleep apnea is a condition where breathing stops intermittently during sleep, often leading to significant health issues. Each episode can last from 10 to 20 seconds or more and is frequently accompanied by a brief arousal from sleep. This disturbance, largely unnoticed by the individual, can lead to severe daytime fatigue. Commonly, individuals seek help after being informed by their partners about loud snoring and noticeable breathing pauses during sleep.
The condition is more prevalent among...

Correlations02:20

Correlations

Correlation means that there is a relationship between two or more variables (such as ice cream consumption and crime), but this relationship does not necessarily imply cause and effect. When two variables are correlated, it simply means that as one variable changes, so does the other. We can measure correlation by calculating a statistic known as a correlation coefficient. A correlation coefficient is a number from -1 to +1 that indicates the strength and direction of the relationship between...

Longitudinal Research02:20

Longitudinal Research

Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

Correlation and Causation01:27

Correlation and Causation

Statistical tests can calculate whether there is a relationship, or correlation, between independent and dependent variables. An indirect relationship of the variables signifies a correlation, while a direct relationship shows causation. If it is determined that no connection exists between the variables, then the correlation is a coincidence.
Correlation versus Causation
If the dependent variable increases or decreases when the independent variable increases, there is a positive or negative...

Insufficient Sleep and Sleep Deprivation01:13

Insufficient Sleep and Sleep Deprivation

Insufficient sleep refers to not getting the recommended amount of sleep for optimal functioning, even if it's just slightly less than needed. Sleep insufficiency may occur due to lifestyle choices, such as staying up late for social events or work, resulting in routinely getting less sleep than required. For example, consistently sleeping 6 hours when the body needs 7-9 hours can lead to cumulative effects on health and well-being.
Sleep deprivation is a more severe form of sleep loss...

Correlation01:09

Correlation

In statistics, two variables are said to be correlated if the values of one variable are associated with the other variable. Depending on the relationship between two variables, correlation can be of three types– positive correlation, negative correlation, and zero correlation.
Two variables, for example, a and b, are said to be positively correlated if both variables move in the same direction. In other words, a positive correlation exists between two variables, a and b, if:
