まとめ
肥満者は、非肥満者と比較して、発声時間短縮、音響測定値の変化など、声の質が低いことを示す。ボディマス指数(BMI)の増加は、声のパラメータの悪化と相関しており、肥満が声の健康に悪影響を与えることを示唆している。
科学分野:
- 耳鼻咽喉科
- 音声言語病理学
- 肥満医学
背景:
- 肥満は世界的に増加している健康問題である。
- 肥満と音声障害の潜在的な関連を示唆するエビデンスが増えている。
- 肥満集団における包括的な音声評価は、健康への影響を理解するために不可欠である。
研究 の 目的:
- 肥満者と非肥満者の音声特性を比較する。
- 聴覚的知覚、音響、自己評価法を用いて音声パラメータを評価する。
- 肥満者におけるボディマス指数(BMI)と音声パラメータの関係を調査する。
主な方法:
- 86人の参加者(肥満者43人、非肥満者43人)を対象とした前向き横断研究。
- 評価には、最大発声時間(MPT)、GRBASスケール、音響分析(F0、ジッター、シマー、HNR、AVQI、ABI、DSI)、音声関連生活の質(V-RQOL)、および音声疲労指数(VFI)が含まれた。
- データは、比較統計およびBMIとの相関分析を用いて分析された。
主要な成果:
- 肥満者は、非肥満者と比較して、MPTが有意に短く、HNRが低く、AVQIおよびABIが高く、DSIが低い(P < 0.005)。
- 肥満者は、V-RQOLが低く、VFIが高い(P < 0.001)と報告し、GRBASの評価も高かった(P < 0.05)。
- BMIは、GRB、MPT、F0、AVQI、ABI、DSI、V-RQOL、およびVFIと中程度かつ有意な相関を示した(P < 0.05)。
結論:
- 肥満は声質に悪影響を与え、音響パラメータと主観的な声の健康に影響を与える。
- BMIが高いほど、声の悪化と関連している。
- 従来の測定法に加えて、多因子音響ツールは、肥満者に対する包括的な音声評価を提供する。

Obesity
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...

Assessment of Ventilation II: Respiratory Depth and Rhythm

Respiratory Depth
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:

Assessment of the Gastrointestinal System II: Health Perception Pattern
456
Assessing the gastrointestinal (GI) system is a complex process that begins with collecting subjective data. This data, collected through patient interviews, provides crucial insights into the patient's health history, perception patterns, and lifestyle habits, all contributing significantly to GI health.
Health Perception Patterns
Health perception patterns offer valuable insights into a patient's lifestyle habits and how they may impact their GI health. These patterns include:

Cross-Sectional Research
12.4K
In cross-sectional research, a researcher compares multiple segments of the population at the same time. If they were interested in people's dietary habits, the researcher might directly compare different groups of people by age. Instead of following a group of people for 20 years to see how their dietary habits changed from decade to decade, the researcher would study a group of 20-year-old individuals and compare them to a group of 30-year-old individuals and a group of 40-year-old...
