在预孕期间个人暴露于热量是适度的,与室外温度的相关性很低. 诸如空调使用等因素并不能显著解释个人热量暴露的变化.
科学领域:
- 环境健康 环境健康
- 生殖流行病学 生殖流行病学
- 个人暴露监测 个人暴露监测
背景情况:
- 升高的温度对怀孕的结果构成风险.
- 户外空气温度经常被用作个人暴露于热量的代理值.
- 室外温度可能不会准确地反映个体体验到的热量.
研究的目的:
- 为了评估预先概念队列中的个人热量暴露.
- 评估个人和室外温度之间的相关性.
- 确定影响个人热暴露相关性变化的因素.
主要方法:
- 使用可穿戴式监视器收集一个月的个人温度和湿度数据.
- 计算个人热量指标 (温度,热量指数) 强度,频率和持续时间.
- 将个人指标与基于居住的室外温度进行比较,分析因环境和人口因素分层的相关性.
主要成果:
- 平均每日个人平均温度为22.9°C;4%的读数超过了极端高温值.
- 在日常平均室内和室外温度 (r=0.33) 之间观察到较低的相关性.
- 参与者内部的中位相关性也很低 (r=0.34),户外时间或空调使用的解释力有限.
结论:
- 在这个美国预孕队伍中,个人热量暴露通常是适度的.
- 个人和户外温度的相关性很弱,这表明户外测量是很差的代理.
- 个人暴露于热量的变化并没有被AC使用或户外时间等因素显著解释.

Equipments Used to Measure Body Temperature
Glass-bulb Thermometer:
Glass-bulb thermometers are hollow glass tubes with a bulb tip containing liquid such as ethanol or mercury. Historically, glass bulb mercury thermometers were the standard device to measure body temperature. Today, mercury thermometers are prohibited in many countries due to the hazardous effects of mercury and the risk of exposure if the glass bulb breaks. In general,...
Assessing Body Temperature - Axilla
Step 1: Perform hand hygiene and put on clean gloves to maintain infection control and prevent cross-contamination.
Step 2: Prepare the patient by explaining the procedure to ensure understanding and cooperation. Ensure privacy, expose the axilla, and inform the patient that minimal movement is crucial for an accurate reading.
Step 3: Adjust the patient’s clothing to expose only the axilla. It minimizes...
Assessing Body Temperature - Temporal Artery
Step 1: Perform hand hygiene and don a fresh pair of gloves to prevent cross-infection and ensure patient safety.
Step 2: Explain the procedure to the patient to establish trust. Clear communication establishes trust with the patient, ensures they understand what to expect, promotes cooperation, and enhances comfort during the procedure.
Step 3: Assess the patient's...
Assessing Body Temperature - Oral
Step 1:
Start by practicing proper hand hygiene to prevent the spread of microorganisms.
Step 2:
Take the thermometer out of the charging unit, switch it on, and wait for the ready sign.
Step 3:
Gently slide the probe cover until a click is heard. This simple action prevents cross-contamination and ensures the correct placement of the probe cover.
Step 4:
Instruct the patient to open their mouth and place...
