まとめ
2歳から19歳の若者の11%以上がBMIの97%のパーセンチルにあるため,小児肥満は依然として懸念事項です. 最近の国内データでは,1999年から2006年にかけての高BMIの流行に重大な変化がないことが示されています.
科学分野:
- 小児内分泌学について
- 公衆衛生 栄養 栄養について
- エピデミオロジー エピデミオロジー
背景:
- 1980年から2004年にかけて,米国の子供や若者の肥満の罹患率は著しく増加しました.
- 現在の高体量指数 (BMI) の流行と傾向を理解することは,公衆衛生の介入にとって極めて重要です.
研究 の 目的:
- 米国の子供と青少年における年齢相応の高BMIの3つの主要な測定値の流行を推定する.
- 測定された身長と体重を含む全国調査データを用いて,年齢に応じて高いBMIの最近の傾向を分析する.
主な方法:
- 2003年,2004年,2005年,2006年の全国保健栄養調査 (NHANES) の8165人の子供と青少年のデータを活用した.
- CDCの成長図に基づいた85パーセント,95パーセント,97パーセントの年齢別BMIと推定罹患率を計算した.
- 1999年から2006年にかけての4つの全国調査期間における傾向を調べた.
主要な成果:
- 2003年から2006年の間に,子どもと青少年 (2~19歳) の11.3%が,年齢別BMIの97%のパーセンチルまたはそれ以上でした.
- 16.3%が95パーセントまたはそれ以上で, 31.9%が85パーセントまたはそれ以上でした.
- 1999年から2006年の間に,男女ともに,年齢相応のBMIの高度の有意な傾向は観察されなかった.
結論:
- 米国の子供と青少年における年齢相応のBMIが高い人の罹患率は,2003~2004年と2005~2006年の間に有意に変化しなかった.
- 1999年から2006年の間に,全国的に年齢に応じて高いBMIの有意な傾向は検出されませんでしたが,この期間中に流行が安定したことを示しています.

Nature and Nurture
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, such as differences...
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...

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 adipocytes...
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)...
Drug Dosing: Obese Patients
In the United States, obesity is a prominent concern. It is linked to heightened mortality rates due to increased occurrences of conditions such as hypertension, atherosclerosis, coronary artery disease, and diabetes compared to nonobese individuals. A patient is classified as obese if their actual body weight surpasses the ideal or desirable body weight by 20%, based on Metropolitan Life Insurance Company data. Ideal body weights consider average weights and heights for males and females...
Anorexia Nervosa
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.
