Levels of Health Promotion and Illness Prevention

14.1K
Health promotion allows a person to control the determinants of health, resulting in an improved health status. It enhances the quality of life and reduces premature deaths. Health promotion and illness prevention programs help people make beneficial choices to reduce the risk of disease and disabilities. There are three health promotion and illness prevention levels: primary, secondary, and tertiary prevention.
In primary prevention, actions taken before disease onset prevent the disease from...

Preventive Healthcare Services

1.8K
Preventive healthcare services keep people healthy via frequent check-ups, screening, and counseling. They primarily aid in disease prevention rather than treating an acute or chronic illness. Preventive treatment also keeps individuals productive and energetic, allowing them to work well into their retirement years. Examples of preventive care services include:

Principles of Disease Surveillance01:26

Principles of Disease Surveillance

439
Disease surveillance is the systematic collection, analysis, and interpretation of health data essential to the planning, implementation, and evaluation of public health practice. This process integrates data dissemination to entities responsible for preventing and controlling disease, injury, and disability. Surveillance systems provide crucial information for action, helping public health authorities make informed decisions to manage and prevent outbreaks, ensure public safety, optimize...

Methods Of Healthcare Delivery System

3.9K
At the different levels of the healthcare system, we see varying methods of healthcare used. These methods include managed care systems, case management, and primary healthcare.
Managed Care System:
The managed care system is designed to control the cost while maintaining the quality of care. The patient's care from admission to discharge is planned by the primary care provider or the case manager, also known as the gatekeeper. In a managed care system, the number of care providers is...

科学分野:

  • 遺伝学
  • 神経科学
  • 集団健康

背景:

  • アルツハイマー病(AD)は認知機能低下と関連しており、APOE4アレルなどの遺伝的要因はリスクを高める。
  • 多因子リスクスコア(PRS)は、AD感受性を予測するために遺伝子変異を蓄積する。
  • 本研究では、ブラジル(SABE)およびヨーロッパ(ADNI)集団におけるPRSモデルを調査し、認知障害に対する遺伝的影響を理解する。

研究 の 目的:

  • 異なる多因子リスクスコア(PRS)モデルが認知障害を予測する有効性を評価する。
  • 遺伝的祖先とAPOE4アレルが、混合系およびヨーロッパ系集団における認知機能に与える影響を調べる。
  • SABEおよびADNIデータセット間でPRSモデルのパフォーマンスを比較する。

主な方法:

  • PRSice-2を使用して、Bel、Kunkle、Kunkle-AFR、およびPRS_SUMモデルを含むPRSを生成した。
  • SABE(ブラジル、n=1,103)およびADNI(ヨーロッパ、n=785)コホートのデータを解析した。
  • 年齢、性別、教育、APOE4の状態、および局所祖量を調整した線形回帰とブートストラップを使用した。

主要な成果:

  • SABEコホートでは、年齢は認知機能に負の影響を与え、教育は正の影響を与えた。APOE4は軽微な影響を示し、ヨーロッパ系祖先を持つ個人でより顕著であった。PRSモデルは分散の26.6-26.8%を説明した。SABEにおける局所祖先解析では、ヨーロッパ系および東アジア系の祖先でホモ接合性が高いことが明らかになった。
  • ADNIコホートでは、APOE4はMMSEスコアに有意な影響を与えた。Kunkle PRSモデル(R2=0.155)は、認知変動性においてKunkle-AFR(R2=0.131)よりも高い予測力を示した。

結論:

  • PRSモデルは、異なる祖先集団間での認知機能に対する予測能力が様々であることを示す。
  • 局所祖先は、SABEコホートのような混合系集団における認知障害の理解にとって重要である。
  • PRSおよびAPOE4を含む遺伝的要因は、高齢化集団における認知機能の健康に影響を与える祖先と複雑に相互作用する。
