Insights

High household chaos is linked to increased infant weight-for-length z-score at 12 months. This study found no evidence that breastfeeding, sleep, or screen time mediate this association in infancy.

Area of Science:

  • Pediatrics
  • Public Health
  • Child Development

Background:

  • Infancy is a crucial period for preventing obesity.
  • Household chaos is linked to adverse health outcomes, but its effect on infant obesity is not well understood.

Purpose of the Study:

  • To investigate the association between household chaos and infant weight-for-length z-score at 12 months.
  • To explore potential mediation by infant sleep and screen time.

Main Methods:

  • Study involved 401 predominantly Black women and infants in the southeastern US.
  • Multivariable linear regressions were used to analyze the relationship between household chaos and infant weight-for-length z-score.
  • Breastfeeding, sleep, and screen time were assessed as potential mediators.

Main Results:

  • Higher household chaos was significantly associated with a greater infant weight-for-length z-score at 12 months (p=0.04).
  • No significant associations were found between household chaos and infant breastfeeding duration, sleep patterns, or screen time.

Conclusions:

  • Increased household chaos is associated with higher infant weight at 12 months.
  • Breastfeeding, sleep, and screen time do not appear to mediate the relationship between household chaos and infant weight in this cohort.

Socioemotional Development during Infancy01:30

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.

Household Wiring And Electrical Safety01:13

Household Wiring And Electrical Safety

Companies that supply power to most modern households use three conductors, typically called a three-wire line. While one is neutral, the other two are both at 120 V but with opposite polarity, giving a voltage of 240 V between them. With a three-wire line, high-power appliances that require 240 V, such as electric stoves and clothes dryers, are linked between the two hot lines. 120 V appliances can be connected between the neutral and either of the hot lines. The neutral side, which is always...

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...

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...

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...

Apparent Weight01:09

Apparent Weight

True weight is the measure of the gravitational force acting on an object. However, if the object accelerates, its measured weight is different from its true weight. Similar observations can be made when the object is submerged in water. An object's weight in water is its apparent weight, which is equal to the difference between its true weight and the buoyant forces.
Consider a person standing on a bathroom scale inside an elevator. If the scale is accurate at rest, its reading equals the...
