まとめ
習慣的に食事を終えること、すなわちプレートクリアは、ボディマス指数に有意な影響を与えないようです。このメタアナリシスでは、皿をきれいにすることと体重増加との間に一般的な関係は見られませんでした。
科学分野:
- 栄養科学;行動科学;公衆衛生
背景:
- 現代の食環境はより大きなポーションサイズを促進し、全体的な食物摂取量を増加させる可能性があります。プレートクリア(ポーション全体を終えること)の実践は、体重増加に寄与すると仮定されています。プレートクリアとボディマス指数(BMI)の関連に関する既存の研究は、一貫性のない結果を示しています。
研究 の 目的:
- プレートクリア傾向とボディマス指数の間の相関関係を調べるメタアナリシスを実施すること。全体的な関係を決定するために複数の研究からの所見を統合すること。
主な方法:
- 22の独立したサンプルからのデータに対してメタアナリシスが実行されました。プール効果を評価し、潜在的なモデレーターを特定するために、メタ回帰を含む統計分析が使用されました。
主要な成果:
- 全体的なプール効果(r = 0.04)は、プレートクリアとBMIの間に有意な関係がないことを示しました。メタ回帰により、サンプル中の女性の割合と使用された特定の自己申告尺度が効果を調整することが明らかになりました。男性およびプレートクリア傾向尺度を使用した場合には、小さな正の関連が存在する可能性があります。
結論:
- 習慣的なプレートクリアは、一般的に体重が多いこととは関連していません。明確な関連がないことは、寄与要因のさらなる調査を保証します。自己申告バイアスが所見に影響を与える可能性がありますが、堅牢な関連がないことは注目に値します。

Reduced Mass Coordinates: Isolated Two-body Problem
2.4K
In classical mechanics, the two-body problem is one of the fundamental problems describing the motion of two interacting bodies under gravity or any other central force. When considering the motion of two bodies, one of the most important concepts is the reduced mass coordinates, a quantity that allows the two-body problem to be solved like a single-body problem. In these circumstances, it is assumed that a single body with reduced mass revolves around another body fixed in a position with an...

Directing Effect of Substituents: meta-Directing Groups
5.8K
Substituents on the benzene ring that direct an incoming electrophile to undergo substitution at the meta position are called meta directors. All meta directors either have a positive charge on the atom directly bonded to the ring or a partial positive charge. These groups function by withdrawing electrons from the ring through inductive and resonance effects. Consider the carbocation intermediates formed upon the addition of an electrophile on nitrobenzene at the...

Mass Spectrometry: Complex Analysis
1.7K
Mass spectrometry is an important technique for the identification of pure compounds. However, it has some limitations for the analysis of complex mixtures, often due to excessive fragmentation making the spectrum too complicated to decipher. Mass spectrometry can be combined with suitable separation methods in sequence, forming hyphenated methods, which are useful in the analysis of complex mixtures.

Atomic Mass
69.7K
Atoms — and the protons, neutrons, and electrons that compose them — are extremely small. For example, a carbon atom weighs less than 2 × 10−23 g. When describing the properties of tiny objects such as atoms, we use appropriately small units of measure, such as the atomic mass unit (amu). The amu was originally defined based on hydrogen, the lightest element, then later in terms of oxygen. Since 1961, it has been defined with regard to the most abundant isotope of carbon, atoms of which...

Molar Mass

The identity of a substance is defined not only by the types of atoms or ions it contains but by the quantity of each type of atom or ion. For example, water, H2O, and hydrogen peroxide, H2O2, are alike in that their respective molecules are composed of hydrogen and oxygen atoms. However, because a hydrogen peroxide molecule contains two oxygen atoms, as opposed to the water molecule, which has only one, the two substances exhibit very different properties.

Body Temperature
1.4K
Body temperature reflects the equilibrium between heat production and heat loss within the body. Most heat is generated by metabolically active tissues, particularly the liver, heart, brain, kidneys, and endocrine organs. At rest, skeletal muscles contribute 20–30% of total heat production, but during vigorous exercise, this can increase up to 30–40 times.
The average body temperature is approximately 37°C (98.6°F) and typically ranges from 36.1–37.2°C...
