概括

超重的成年人身体组成的变化因性别和年龄而异. 年龄较大的雄性增加脂肪并失去肌肉,而雌性显示的变化较小. 中枢脂肪和肉症随着年龄的增长而增加.

科学领域:

肥胖问题研究研究
老年学是一门学科.
身体组成分析身体成分分析

背景情况:

超重或肥胖个体的身体组成 (BC) 变化尚未得到充分理解.
像体质指数 (BMI) 这样的现有指标可能无法完全捕捉年龄和性别特定的BC变化.

研究的目的:

调查超重或肥胖的成年人中性别和年龄组之间的身体组成模式如何不同.
为了识别与年龄相关的脂肪分布和肌肉质量的变化,特别是中心脂肪和肉.

主要方法:

双能X射线吸收计 (DXA) 用于评估2844名意大利成年人 (BMI≥25 kg/m2) 的BC.
参与者被分为三个年龄组:年轻人 (20-39岁),中年 (40-59岁) 和老年人 (60-80岁),根据体重和BMI进行匹配.

主要成果:

男性的总体脂肪百分比增加,随着年龄的增长,总肌肉量减少.
在不同年龄组的女性中,总体脂肪和肌肉质量变化不那么明显.
中年和老年人,不论性别,与年轻人相比,干脂肪百分比更高,尾肌肉质量较低,这表明中心脂肪和肉.

结论:

体重指数 (BMI) 在检测超重/肥胖人口中与年龄相关的身体组成差异方面有限.
需要新的评估工具来更好地描述这些人口中的身体组成.
需要进一步的研究,以了解这些性别和年龄特定的BC模式对健康的影响.

关键词:

Obesity

Obesity

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...

Changes in the Appendicular Skeleton with Age

Changes in the Appendicular Skeleton with Age

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...

Bias in Epidemiological Studies

Bias in Epidemiological Studies

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:

Bone Disorders

Bone Disorders

Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Signs of Puberty

Signs of Puberty

Puberty is a critical phase, typically beginning between the ages of 8 and 13 in girls and 9 and 14 in boys, though timing can vary based on genetics, environmental factors, and overall health. This period is characterized by the development of secondary sexual characteristics and the attainment of reproductive potential. Endocrine changes underpin puberty, with hormonal surges of Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH) instigated by Gonadotropin-Releasing Hormone (GnRH)...

Two-Way ANOVA

Two-Way ANOVA

The two-way ANOVA is an extension of the one-way ANOVA. It is a statistical test performed on three or more samples categorized by two factors - a row factor and a column factor. Ronald Fischer mentioned it in 1925 in his book 'Statistical Methods for Researchers.'
The two-way ANOVA analysis initially begins by stating the null hypothesis that there is an interaction effect between the two factors of a dataset. This effect can be visualized using line segments formed by joining the...
