概括
中心的肥胖指标,如腰与身高的比率 (WHtR),比BMI更好地预测健康风险,特别是在老年人中. 肥胖患病率随着时间的推移而增加,由年龄驱动,而不是队列效应.
科学领域:
- 公共卫生 公共卫生
- 流行病学 流行病学
- 老年学是一门学科.
背景情况:
- 中央肥胖度量 (WC,WHR,WHtR) 在预测健康风险方面优于BMI.
- 在老年人中,BMI往往低估了肥胖的诊断.
- 对于肥胖指标的高风险分类,已有确定的值.
研究的目的:
- 为了比较中央肥胖测量与BMI在预测不同年龄组的健康风险方面的有效性.
- 分析使用各种措施对肥胖患病率的年龄,周期和队列效应.
- 评估腰与身高比率 (WHtR) 作为与年龄相关的肥胖风险的一致指标的适用性.
主要方法:
- 利用英格兰健康调查数据 (2005-2021) 来自120,024名 (11-89岁) 个人.
- 定义了高风险分类,使用了WC,WHR,WHtR和BMI的既定值.
- 使用后勤回归与分组变量来评估年龄,时期和队列效应 (APC分析).
主要成果:
- 所有措施的肥胖率随着时间的推移而增加,中心措施显示了直线年龄趋势,直到70岁.
- 体重指数表现出一个反转的U形年龄趋势,与中心肥胖症的线性增加不同.
- 腰与身高比率 (WHtR) 的趋势反映了BMI人口水平,但确定了不同的高风险个体;高风险的WHtR随着年龄的增长而显著增加,特别是在老年人中.
结论:
- 与BMI相比,腰与身高的比率 (WHtR) 提供了与年龄相关的肥胖风险的更一致的反映.
- 随着年龄的增长,中心肥胖率的线性增加与已知的肥胖相关并发症增加一致.
- 人口老龄化预计将推动整体肥胖患病率的进一步增加.

Obesity
1.1K
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...

Longitudinal Research
13.0K
Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

Longitudinal Studies
454
Longitudinal studies are also widely used in other medical and social science fields. For instance, in cardiovascular research, they can monitor patients' health over decades to identify risk factors for heart disease, such as high cholesterol or smoking, and evaluate the long-term effectiveness of preventive measures. Similarly, in mental health studies, researchers might follow individuals from adolescence into adulthood to understand the development and progression of conditions like...

Bias in Epidemiological Studies
1.2K
Biases can arise at various stages of research, from study design and data collection to analysis and interpretation. Recognizing and addressing these biases is essential to ensure the validity and reliability of epidemiological findings.Broadly speaking, biases in epidemiology fall into three main categories: selection bias, information bias, and confounding. A more detailed description of possible biases is:

Lifestyle Factors and Health
397
Lifestyle factors play a critical role in maintaining overall health and preventing chronic diseases. Key elements, such as regular physical activity, a nutritious diet, and abstinence from smoking, can significantly enhance physical, mental, and emotional well-being while reducing the risk of several life-threatening conditions.
Benefits of Physical Activity
Physical activity, whether through structured exercise or casual activities like walking, biking, or dancing, is a cornerstone of a...

Changes in the Appendicular Skeleton with Age
3.3K
The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
