背景:
- 1978年から1991年の間に,米国における肥満と体重過剰の流行率は増加しました.
- 以前の報告では,継続的な上昇を示していたが,自己報告データに依存しており,客観的な測定で検証する必要があった.
研究 の 目的:
- 米国の成人における過体重 (体量指数 (BMI) ≥25) と肥満 (BMI ≥30) の傾向と罹患率を調査する.
- 測定された身長と体重データを正確に評価するために使用し,以前の自己報告された推定値と対照的にします.
主な方法:
- 1999~2000年に成人の男女4115人を対象に調査が行われました.
- データは,米国国民全体の代表的なサンプルを確保するために,国立健康と栄養検査調査 (NHANES) の一部として収集されました.
- 年齢調整された罹患率を計算し,以前の調査と比較し,異なる性別,年齢層,人種/民族のカテゴリーの具体的な見積もりを行いました.
主要な成果:
- 年齢調整された肥満の罹患率は,1988年から1994年にかけての22.9%から1999年から2000年の間に30.5%に上昇した (NHANES III).
- 肥満の罹患率は,同じ期間に55.9%から64.5%に増加した.
- 極端な肥満 (BMI ≥40) も,2.9%から4.7%に大幅に増加しました. 増加はほとんどの人口集団で観察され,非ヒスパニック系黒人女性の割合が最も高かった.
結論:
- 米国で観察された肥満と過体重の増加傾向は1999年から2000年まで続いた.
- この発見は,過剰体重と肥満を減らすための戦略が公衆衛生にとって極めて重要であることを強調しています.
- 測定されたデータは,BMIカテゴリーの有意な増加を確認し,効果的な公衆衛生介入の必要性を強調しています.

1.6K
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...

01:21Drug 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...

01:25Pharmacokinetics in Obese Patients: Drug Absorption and Distribution

Obesity significantly alters the pharmacokinetic processes of drug absorption and distribution, presenting unique challenges in medical treatment. The increased fat tissue and decreased lean muscle in obese individuals can significantly affect how drugs are absorbed into the body and distributed across different tissues. This alteration can lead to variances in the effectiveness and safety of medications, necessitating adjustments in dosing or drug selection for obese patients.One notable...

01:20Pharmacokinetics in Obese Patients: Drug Metabolism and Excretion

Drug metabolism, a critical process in the liver, involves two primary phases: Phase I reactions and Phase II conjugation. Obesity introduces significant alterations in this metabolic process, primarily due to fatty infiltration of the liver, leading to conditions such as nonalcoholic fatty liver disease (NAFLD). This condition can modify the activities of both Phase I and II enzymes, impacting how drugs are metabolized in obese patients.Phase I metabolism sees variable effects across...

In statistical epidemiology and health sciences, two essential metrics—prevalence and incidence—are fundamental for understanding disease dynamics within a population. These measures enable public health officials, epidemiologists, and researchers to assess the burden of diseases, allocate resources effectively, and design impactful public health policies and interventions.
Prevalence indicates the proportion of individuals in a population who have a specific disease or health...

Binge eating disorder is a significant mental health condition characterized by recurrent episodes of excessive food consumption within a short period, accompanied by a perceived loss of control over eating behavior. Unlike occasional overeating, binge eating disorder is marked by distressing emotions such as guilt, shame, and anxiety following binge episodes. The disorder affects individuals across different ages and backgrounds, with profound implications for physical and psychological...
