概括
老年人在家外度过的时间增加与住院治疗减少有关. 这一发现表明,社区流动性是老年人健康状况的关键指标.
科学领域:
- 老年学是一门学科.
- 公共卫生 公共卫生
- 数字健康数字健康
背景情况:
- 居住在社区的老年人是健康结果研究的焦点.
- 评估流动性对于了解老年人的健康风险至关重要.
- 全球定位系统 (GPS) 技术为测量社区流动性提供了新的方法.
研究的目的:
- 调查GPS测量社区流动性与老年人的健康结果之间的关联.
- 为了确定流动性指标是否预测住院,急诊室 (ED) 访问和跌倒.
- 探索GPS数据在老年健康研究中的实用性.
主要方法:
- 一项涉及148名老年人 (平均年龄76.9岁) 的随机试验的二次分析.
- 参与者在干预后佩戴GPS设备,收集1年多的移动数据.
- 一般化的线性模型分析了GPS移动指标 (例如,外出时间) 与事件健康事件之间的关系,并对共变量进行调整.

01:26Levels of Health Promotion and Illness Prevention
12.7K
Health promotion allows a person to control the determinants of health, resulting in an improved health status. It enhances the quality of life and reduces premature deaths. Health promotion and illness prevention programs help people make beneficial choices to reduce the risk of disease and disabilities. There are three health promotion and illness prevention levels: primary, secondary, and tertiary prevention.
In primary prevention, actions taken before disease onset prevent the disease from...

01:30Types of Global Positioning System Surveys
77
GPS surveying methods vary in application, accuracy, and data collection techniques, catering to diverse surveying and mapping needs. Static GPS, kinematic GPS, and real-time kinematic (RTK) surveying are widely used. Each technique offers distinct advantages.Static GPS involves placing one receiver at a known reference point and another at the target point. It collects exact positional data by observing multiple satellite ranges over an extended period, achieving centimeter-level accuracy for...

70
Surveyors use Global Positioning System (GPS) technology to measure the precise location and elevation of points on Earth. In a recent survey, GPS receivers were used to determine the coordinates and elevations of two park monuments. The process involved careful mission planning, data collection, and correction to ensure accuracy. The survey began with mission planning to identify optimal satellite visibility and minimize Position Dilution of Precision (PDOP). A geodetic control point...
