まとめ
バイナリ調整は,連続調整と比較して健康格差を過大評価する. 障害のない健康的な平均寿命の測定値のスケーリングを調整することで,品質調整された平均寿命と比較しやすくなり,健康の公平性分析を改善します.
科学分野:
- 健康経済学 医療経済学
- 公衆衛生は公衆衛生である.
- 社会流行病学 社会流行病学とは
背景:
- 健康関連の生活の質 (HRQOL) の調整は,健康における社会的不平等の推定に大きく影響する.
- 分配費用対効果分析 (DCEA) は,健康格差の正確な測定に依拠し,公平性の重み付けを行う.
- バイナリと継続的なHRQOLの調整の選択は,健康の公平性に関する政策に関連する結論に影響を与える可能性があります.
研究 の 目的:
- バイナリ対連続HRQOLの調整が,生涯の健康における社会的不平等の推定にどのように影響するか調査する.
- これらの調整がDCEA.内の株式重量に及ぼす影響を調査する.
- 品質調整寿命 (QALE),無障害寿命 (DFLE),健康寿命 (HLE) を含む,寿命の異なる測定値を比較する.
主な方法:
- 英国の2018年の健康調査とONSの死亡率/人口データを利用した.
- QALE (EQ-5D-5L),DFLE (長期的な病気を制限する),HLE (自己評価された健康) の近所の欠乏クインティルの健康分布を比較した.
- アトキンソン不平等回避パラメータと,年齢と貧困による HRQOL のクロステーブル化を使用して,間接的資本重量を引き出した.
主要な成果:
- 継続的調整は,バイナリ調整と比較して,最も貧乏なクインティルと最も貧乏なクインティルの間の格差のギャップが小さいことを明らかにしました (QALE: 11.25,DFLE: 16.00,HLE: 18.53).
- バイナリ調整は,特に格差の嫌悪性の高いレベルでは,実質的により高い株式重量をもたらしました.
- 社会集団のHRQOLの差異は,罹病率とその負担の両方によって引き起こされ,罹病率はより大きな要因であった.
結論:
- 障害のない健康的な寿命の測定は,バイナリスケーリングにより,品質調整寿命よりも大きな推定健康格差を示しています.
- バイナリスケーリングは,暗黙的に,障害や健康状態の悪さ,すなわち死亡にゼロのHRQOL値を割り当てます.
- バイナリスケールのエンドポイントの簡単な調整は,これらの測定値の比較性を高め,健康の公平性評価を改善することができます.

Self-Discrepancy and Its Effects
339
Self-discrepancy theory explains how people compare their actual self to their ideal and ought selves and how mismatches between these self-guides can lead to emotional distress. Developed by E. Tory Higgins, the theory distinguishes among three components of self-concept: the actual self, the ideal self, and the ought self. These refer respectively to how individuals perceive themselves, how they aspire to be, and how they believe they are obligated to be. Emotional well-being, self-esteem,...

Bias in Epidemiological Studies
1.4K
Biases can arise at various stages of research, from study design and data collection to analysis and interpretation. Recognizing and addressing these biases is essential to ensure the validity and reliability of epidemiological findings.Broadly speaking, biases in epidemiology fall into three main categories: selection bias, information bias, and confounding. A more detailed description of possible biases is:

One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.

Intellectual Disability

Intellectual disability (ID) is a neurodevelopmental condition characterized by deficits in intellectual and adaptive functioning that manifest during the developmental period. This condition encompasses challenges in reasoning, memory, problem-solving, and learning, accompanied by impairments in everyday life skills, such as communication, self-care, and social interactions. Intellectual disability affects approximately 1% of the population in the United States, impacting an estimated 5...

Factors Affecting Illness

When a person's physical, emotional, intellectual, social development or spiritual functioning is compromised, this deviation from a healthy normal state is called illness. Illness creates stress that in turn harms individuals. Irritation, anger, denial, hopelessness, and fear are behavioral and emotional changes an individual experiences in the phases of illness. A variety of factors influence a person's health and well-being.
For instance, risk factors are connected to illness,...

Life tables are versatile across various fields, providing a quantitative basis for analyzing mortality and survival rates. Whether used by demographers, actuaries, epidemiologists, or sociologists, life tables offer valuable insights into the dynamics of life and death, facilitating informed decisions in public health, insurance, conservation, and beyond. Their broad applicability highlights the interconnectedness of demographic data with practical outcomes in everyday life and strategic...
