Insights

High birth weight (HBW) in infants is linked to childhood overweight and obesity. Exclusive breastfeeding for six months significantly reduces this risk, offering a protective effect.

Area of Science:

  • Pediatrics
  • Public Health
  • Childhood Obesity

Background:

  • Birth weight (BW) is positively associated with body mass index (BMI) in children.
  • Understanding BMI trajectories based on BW status is crucial for early intervention.

Purpose of the Study:

  • Investigate BMI trajectory across different birth weight categories.
  • Evaluate the protective effect of breastfeeding on overweight/obesity prevalence at age 6.

Main Methods:

  • Retrospective cohort study (2008-2016) with 38,049 Korean children.
  • Analysis of health check-up data from birth to 6 years.
  • Logistic regression to assess associations between birth weight status (LBW, NBW, HBW) and growth development.

Main Results:

  • High birth weight (HBW) infants showed increased odds of being overweight/obese (OR, 1.70-2.35) compared to normal birth weight (NBW) infants.
  • Low birth weight (LBW) infants had higher odds of being underweight (OR, 1.69-2.20).
  • Breastfeeding HBW infants for 6 months significantly reduced overweight/obesity risk (OR, 0.54-0.76).

Conclusions:

  • High birth weight is a significant risk factor for childhood overweight and obesity.
  • Exclusive breastfeeding serves as a protective factor against overweight/obesity in high birth weight children.

Birth Control Methods01:22

Birth Control Methods

Vasectomy is a surgical form of male sterilization that involves severing and sealing the vasa deferentia, preventing sperm from mixing with semen during ejaculation. Because a vasectomy does not impact the testes' ability to produce testosterone, hormone levels, libido, and sexual function generally remain unchanged. While vasectomy is highly effective in preventing pregnancy, with a success rate near 99.85%, rare cases of recanalization (spontaneous reconnection) can occur. Although...

Obesity01:24

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...

Weighted Mean00:57

Weighted Mean

While taking the arithmetic, geometric, or harmonic mean of a sample data set, equal importance is assigned to all the data points. However, all the values may not always be equally important in some data sets. An intrinsic bias might make it more important to give more weightage to specific values over others.
For example, consider the number of goals scored in the matches of a tournament. While computing the average number of goals scored in the tournament, it may be more important to...

Mass and Weight01:19

Mass and Weight

Mass and weight are often used interchangeably in everyday conversation. For example,  medical records often show our weight in kilograms, but never in the correct units of newtons. In physics, however, there is an important distinction. Weight is the pull of the Earth on an object. It depends on the distance from the center of the Earth. Weight dramatically varies if we leave the Earth's surface, unlike mass, which does not vary with location. On the Moon, for example, the...

Atomic Weight01:25

Atomic Weight

Protons and neutrons have approximately the same mass, about 1.67 × 10-24 grams. Scientists arbitrarily define this amount of mass as one atomic mass unit (amu) or one Dalton. Electrons are much smaller in mass than protons, weighing only 9.11 × 10-28 grams, or about 1/1800 of an atomic mass unit. As a result, they do not contribute much to an element's overall atomic mass. This means that, when considering atomic mass, it is customary to ignore the mass of any electrons and...
