まとめ
栄養不良の二重負担は 低所得国において増加しており 原因は 肥満と肥満の増加です これは,食糧システムと身体活動への介入の緊急の必要性を強調しています.
科学分野:
- 世界保健
- 栄養学的流行病学
- 公衆衛生政策
背景:
- 栄養不良と肥満の共存によって特徴づけられる 栄養不良の二重負担 (DBM) は,低所得国および中所得国 (LMICs) の重要な公衆衛生上の課題である.
- DBMはLMICに不釣り合いな影響を及ぼし,最も貧しい国々で顕著な増加が観察されています.
- インドネシアは,アジアやサハラ以南のアフリカの多くの国々と共に,深刻なDBMを持つ国の例です.
研究 の 目的:
- 低所得国におけるDBMの動態を記述し,社会経済レベルの違いを調査する.
- 過剰体重と肥満に焦点を当てて,DBMの増加の主な要因を特定する.
- 様々なレベルでDBMに取り組むための潜在的な戦略を探求する.
主な方法:
- この研究は,LMICにおけるDBMに関する既存のデータと文献の包括的なレビューと分析を含むシリーズ論文です.
- この分析は,社会経済的地位によって差異化され,DBMの傾向と決定因子に焦点を当てています.
- この論文は,DBMに寄与する食品システムと身体活動パターンの変化を調査しています.
主要な成果:
- DBMは最も貧しいLMICで増加しており,主に肥満と肥満率の上昇によって引き起こされています.
- 食料システムの急速な変化や 低価格の超加工食品や飲料の普及が 重要な要因です
- テクノロジー導入に伴う 労働,交通,家庭,レジャー分野における 身体活動の大幅な減少も 重要な役割を果たしています
結論:
- 最低所得のLMICは重度のDBMを経験し,肥満が主な直接的な原因である.
- これらの要因を理解することは,DBMと闘うための標的型介入の開発に不可欠です.
- DBMに取り組むには,食品環境と身体活動の促進に焦点を当てた多層のアプローチが必要です.

808
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.

608
Bulimia nervosa is a complex and severe eating disorder characterized by a cyclical pattern of binge-and-purge eating pattern. It generally involves an episode of binge eating, followed by compensatory behaviors such as vomiting, excessive exercise, laxative use, or fasting, to prevent weight gain. Despite often maintaining a normal weight, individuals with bulimia are intensely preoccupied with their body image and harbor an overwhelming fear of gaining weight. This can contribute to the...

646
Parenteral Nutrition (PN) delivers essential nutrients directly into the bloodstream, bypassing the digestive system. It is commonly used for individuals with severe digestive disorders or conditions that prevent normal nutrient absorption.
PN can be administered through two primary routes:
1. Central Parenteral Nutrition (CPN):
CPN involves delivering a high concentration of nutrients through a large vein. This is typically achieved using a Peripherally Inserted Central Catheter (PICC) or,...

01:10Nature and Nurture
22.0K
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,...

01:24Obesity
1.1K
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...

01:19Energy Balance
972
The human body gets energy from the three macronutrients: carbohydrates, proteins, and fats. Energy is released when the chemical bonds in the organic compounds present in the food are broken down. The energy content of food is measured in kilocalories (kcal), defined as the amount of heat required to raise the temperature of one kilogram of water by one degree Celsius. This value is determined by measuring the temperature change of the water surrounding a calorimeter after the complete...
