Insights

Adiposity rebound (AR), a rise in BMI in childhood, typically occurs before age 5. Early AR is linked to breastfeeding, diet, and reduced sugary drink intake, influencing underweight and overweight patterns.

Area of Science:

  • Pediatrics
  • Public Health
  • Childhood Obesity

Background:

  • Adiposity rebound (AR) signifies a critical phase in childhood growth, marking the second rise in body mass index (BMI).
  • Understanding the timing and determinants of early adiposity rebound (EAR) is crucial for addressing childhood weight trajectories.

Purpose of the Study:

  • To determine the timing of AR in a large cohort of Korean children.
  • To identify key factors influencing the risk of early AR (EAR).

Main Methods:

  • Utilized large-scale, nationwide longitudinal data from 142,668 Korean children tracked across seven age periods (4-71 months).
  • Analyzed body mass index (BMI) patterns to identify AR timing and associated risk factors for EAR.
  • Examined sex-specific parameters predicting EAR risk.

Main Results:

  • The average AR occurred before 5 years of age (54-60 months).
  • EAR was associated with distinct BMI patterns, including M-shaped curves for underweight and W-shaped curves for overweight/obese children.
  • Adequate breastfeeding, diet, and reduced sugar-sweetened beverage consumption were identified as protective factors against EAR.

Conclusions:

  • This study provides the first large-scale, nationwide data on AR timing and EAR determinants in Korean infants and children.
  • Early intervention focusing on breastfeeding, diet, and limiting sugar-sweetened beverages may help mitigate risks associated with EAR.

Obesity

The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in...

Regression Toward the Mean

Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when...

Socioemotional Development during Infancy

Socio-emotional development in infancy is primarily shaped by early emotional responses and social connections, with temperament playing a central role. Temperament refers to the consistent patterns in an individual's emotional and behavioral responses, observable even in infancy. By examining temperament, researchers can better understand an infant's unique ways of interacting with the world, influencing subsequent personality and socio-emotional growth.
