概括
非常早产的婴儿与满期婴儿的身体组成不同,但晚期早产的婴儿没有. 晚些时候的体重增长比早期的增长更大程度上影响了儿童的身体组成.
科学领域:
- 儿科生长和发育的发展.
- 身体组成分析分析.
- 新生儿研究新生儿研究
背景情况:
- 出生时的妊娠年龄是影响婴儿发育的关键因素.
- 了解产后生长模式对于评估长期健康结果至关重要.
- 儿童时期的身体组成差异可能会对未来的健康产生影响.
研究的目的:
- 调查出生时妊娠年龄与儿童身体组成之间的关系.
- 为了检查产后生长轨迹如何影响儿童的身体组成.
- 为了比较非常早产,晚期早产和满期出生的孩子之间的身体组成.
主要方法:
- 在不同妊娠年龄 (非常早产,晚期早产,终产) 出生的新西兰儿童的纵向研究.
- 在2岁和6岁时使用生物电阻测量身体成分 (脂肪质量指数,无脂肪质量指数).
- 计算条件增长率 (出生-2岁,2-6岁) 和使用多变量线性回归的分析.
主要成果:
- 非常早产的孩子在2岁和6岁时,体重,身高,脂肪质量指数和无脂肪质量指数都较低,相比于按时出生的孩子.
- 晚期早产儿和晚期早产儿之间没有观察到身体组成的显著差异.
- 2至6岁之间的体重增长与6岁的身体组成 (脂肪质量和无脂肪质量) 与早期的增长或身高增长相比,显示出更强的关联.
结论:
- 非常早产的婴儿在2岁和6岁时的身体组成不同,与按期出生的婴儿相比.
- 与晚期早产相比,晚期早产似乎不会显著改变儿童的身体组成.
- 婴儿后期 (2-6岁) 的产后体重增加比早期的生长阶段更为重要,它决定了人体构成.

01:10Nature and Nurture
20.4K
Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience,...

01:27Signs of Puberty
246
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)...

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...

01:09Changes in the Appendicular Skeleton with Age
1.8K
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...

01:28Anorexia Nervosa
43
Anorexia nervosa is a complex and severe eating disorder characterized by an intense fear of weight gain, an unrelenting pursuit of thinness, and a distorted body image. It often leads to dangerously low body weight relative to an individual's age and height. This disorder is marked by significant physical and psychological consequences, making it one of the most life-threatening psychiatric illnesses.

01:07Teratogenicity
2.3K
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
