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...
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 acceleration due to...

Variation in Acceleration due to Gravity near the Earth's Surface01:20

Variation in Acceleration due to Gravity near the Earth's Surface

An object's apparent weight is its weight measured by a spring balance at its location. It is different from its true weight, the force with which the Earth pulls it, because of the Earth's rotation. Mathematically, an object's apparent weight equals its true weight minus the centripetal force that keeps it in a circular motion along with the Earth's surface every 24 hours.
The difference between the true and apparent weights is proportional to the square of the Earth's angular speed. Since the...
Regression Toward the Mean01:52

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 researchers try to extrapolate results...
Self-Discrepancy and Its Effects01:29

Self-Discrepancy and Its Effects

Self-discrepancy theory explains how people compare their actual self to their ideal and ought selves and how mismatches between these self-guides can lead to emotional distress. Developed by E. Tory Higgins, the theory distinguishes among three components of self-concept: the actual self, the ideal self, and the ought self. These refer respectively to how individuals perceive themselves, how they aspire to be, and how they believe they are obligated to be. Emotional well-being, self-esteem,...

Summary
This summary is machine-generated.

Women often misreport pre-pregnancy weight and gestational weight gain (GWG). Overweight and obese individuals particularly underestimate weight, impacting Institute of Medicine (IOM) guideline adherence.

Area of Science:

  • Obstetrics and Gynecology
  • Maternal Health
  • Nutritional Science

Background:

  • Accurate pre-pregnancy weight and gestational weight gain (GWG) are crucial for maternal and infant health.
  • The Institute of Medicine (IOM) provides guidelines for recommended GWG based on pre-pregnancy body mass index (BMI).
  • Self-reported weights are commonly used but may differ from documented values.

Purpose of the Study:

  • To compare self-reported pre-pregnancy and delivery weights with documented values.
  • To assess differences between self-reported and documented GWG.
  • To evaluate discrepancies in BMI and GWG categorization relative to IOM guidelines.

Main Methods:

  • Retrospective analysis of 234 women with documented height, self-reported, and documented weights.
  • Calculated differences between self-reported and documented pre-pregnancy weights and delivery weights.
  • Determined GWG using documented weights and compared against IOM criteria.

Main Results:

  • Self-reported pre-pregnancy weight was significantly lower than documented weight (2.94 kg less, p < 0.0001).
  • Self-reported BMI was lower than documented BMI (1.11 mg/kg², p < 0.0001).
  • Self-reported GWG was significantly higher than documented GWG (3.01 kg greater, p < 0.0001).

Conclusions:

  • Overweight and obese women tend to underestimate their pre-pregnancy weight.
  • These women also overestimate their GWG, potentially misclassifying adherence to IOM guidelines.
  • Discrepancies highlight the need for accurate weight documentation in clinical practice.
