Primary Healthcare Services

1.9K
Primary care promotes wellness and prevents disease. This care includes health promotion, education, protection (such as immunizations), early disease screening, and environmental considerations. Settings providing this type of healthcare include physician offices, public health clinics, school nursing, and community health nursing.
In 1978, international leaders convened in Alma-Ata, Kazakhstan, for what would be a pivotal event in global health. The Alma-Ata Declaration was the first to call...

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...

科学领域:

  • 神经科学是一个神经科学.
  • 遗传学 是一个遗传学.
  • 老年学是指老年学的学科.

背景情况:

  • 早期更年期与认知能力下降和痴呆症有关.
  • 该BDNF Val66Met多态 (Met等位基) 与脑衍生的神经营养因子减少和较差的认知结果有关.
  • 身体活动可以提高BDNF水平,可能抵消早期更年期或Met等位基运输的认知缺陷.

研究的目的:

  • 研究更年期时年龄,BDNF基因型 (Met载体) 和体力活动对更年期后妇女认知功能的相互作用影响.
  • 为了确定身体活动是否可以减轻早期更年期和BDNF Met等位基因的负面认知影响.

主要方法:

  • 利用了加拿大长度老龄化研究 (N=8,101名绝经后妇女) 的基线数据.
  • 评估BDNF Val66Met基因型,自我报告的更年期年龄,以及使用PASE评分的身体活动.
  • 通过神经心理测试和线性回归模型分析了全球认知,并根据共变量进行调整.

主要成果:

  • 较早的更年期和较低的体力活动独立地与较差的认知分数有关.
  • 单独BDNF Met携带并没有显著影响认知.
  • 一个显著的三方相互作用表明,较高的体力活动减轻了早期更年期的负面认知影响在Met载体中,但不是在非载体中.

结论:

  • 更年期的年龄,BDNF基因型和身体活动相互作用,影响更年期后妇女的认知功能.
  • 身体活动似乎特别有利于保持早期更年期的女性的认知健康,并携带BDNF Met等位基因.
