まとめ

幼児の肥満は後に潰瘍性大腸炎を発症するリスクが高くなります幼児の体量指数 (BMI) と炎症性腸疾患 (IBD) の関連性を理解するには,さらなる研究が必要である.

科学分野:

小児の健康
胃腸内科
流行病学について

背景:

子どもの肥満や肥満は免疫機能に潜在的影響を及ぼす世界的な健康問題です
幼児のボディマス指数 (BMI) と炎症性腸疾患 (IBD) の発症リスクとの関係を調べることは極めて重要です.

研究の目的:

幼児の体量指数 (BMI) と,その後の炎症性腸疾患 (IBD) のリスクとの関連を調べる.
誕生から子供期までのBMIの軌道を分析し,IBDの発達との相関を分析する.

主な方法:

スカンジナビアの2つの大規模な出生コホート (ABISとMoBa) を利用し,長期の追跡調査を行った.
生まれてから7~8歳までの年齢別BMIパーセンチルとカテゴリー (体重不足,体重正常,体重過剰,肥満) を評価.
IBDリスクは,複数のコバリアートに調整し,ランダム効果モデルをプーリングして分析した.

主要な成果:

7~8歳の肥満児では,性大腸炎のリスクが有意に増加することが観察された (総合調整された危険比率[aHR] = 5. 10).
3歳の子供の肥満と後のIBDリスクとの間に有意な関連性は見つかりませんでした.
早期のBMIの軌跡はIBDの発症との一貫した関連性を示さなかった.

結論:

7~8歳の子供の肥満は,潰瘍性大腸炎を発症するリスクが高くなります.
この発見は子どもの肥満への対処の重要性を強調しています肥満がもたらす長期的な健康への影響が大きいからです
幼児の肥満と潰瘍性大腸炎の関連メカニズムを明らかにするためにさらなる研究が必要である.

Anatomy of the Intestines

73.9K

Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the...

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy

419

Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

Inflammatory Bowel Disease II: Crohn's Disease

382

Introduction
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...

Inflammatory Bowel Disease I: Ulcerative Colitis

321

Introduction
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Chronic Bowel Disorders: Introduction

540

Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

Irritable Bowel Syndrome I: Introduction

375

Irritable Bowel Syndrome (IBS) is characterized by functional disturbances in the gastrointestinal system, presenting a cluster of symptoms without evident structural or biochemical abnormalities. It primarily affects the large intestine and may cause abdominal pain, bloating, excessive gas, diarrhea, constipation, or both.
IBS is a chronic condition that can persist over a long period or recur frequently.
The pathogenesis of IBS involves a complex interplay of the following factors:
Altered...
