概括
与BMI较低的人相比,肥胖 (BMI≥30) 个体在分娩期间没有报告较低的感知控制. 然而,最高BMI类别 (≥40) 显示出降低分娩控制的趋势,在调整后,这一趋势在统计学上并不显著.
科学领域:
- 产科和妇科 产科和妇科
- 孕产妇和胎儿医学 孕产妇和胎儿医学
- 生殖健康 生殖健康
背景情况:
- 增加的身体质量指数 (BMI) 与更高的围产期精神健康障碍率有关.
- 在分娩期间感知到缺乏控制与分娩后情绪和焦虑障碍有关.
- 体重指数和劳动控制经验之间的关系仍未得到充分研究.
研究的目的:
- 评估与BMI<30 kg/m2的人相比,BMI≥30 kg/m2的个体对分娩的感知控制.
- 调查不同BMI类别与劳动控制经验之间的关联.
主要方法:
- 一项涉及产后患者的横截面研究的二次分析.
- 使用劳工代理度量 (LAS) 来衡量对劳动力的感知控制.

01:24Obesity
510
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...

01:19Mass and Weight
11.7K
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...

01:52Regression Toward the Mean
6.3K
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...

One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.

01:28Apparent Weight and the Earth's Rotation
3.6K
Since all objects on the Earth's surface move through a circle every 24 hours, there must be a net centripetal force on each object, directed towards the center of that circle. The points of the north and south poles are the only exception to this rule.
For an object on the Earth's equator, the net centripetal force that accounts for its rotation is the Earth's pull towards its center, or the weight minus the normal force that prevents it from piercing into the Earth's surface....

01:12Reduced Mass Coordinates: Isolated Two-body Problem
1.3K
In classical mechanics, the two-body problem is one of the fundamental problems describing the motion of two interacting bodies under gravity or any other central force. When considering the motion of two bodies, one of the most important concepts is the reduced mass coordinates, a quantity that allows the two-body problem to be solved like a single-body problem. In these circumstances, it is assumed that a single body with reduced mass revolves around another body fixed in a position with an...
