概括
通过正常化差异植被指数 (NDVI) 衡量的城市绿色与COVID-19大流行期间抑郁症的几率较低有关. 更高的绿色带来了保护作用,尤其对那些社会经济地位较低的人来说.
科学领域:
- 环境心理学
- 公共卫生
- 流行病学
背景情况:
- 城市绿色与改善心理健康,减少抑郁和孤独有关.
- 在COVID-19大流行期间,绿色对抑郁症的影响仍未得到充分研究.
- 这项研究考察了加拿大成年人在疫情期间的城市绿色与抑郁之间的联系.
研究的目的:
- 调查住宅绿化与COVID-19大流行期间患抑郁症的几率之间的关系.
- 评估疫情前的抑郁状态是否会改变绿色对疫情相关的抑郁的影响.
- 探索绿色与抑郁之间的社会经济差异.
主要方法:
- 分析了来自加拿大长度研究中的13,130名加拿大成年人 (50岁以上).
- 使用大流行前和大流行后6个月的CES-D-10尺度来评估抑郁症.
- 在500米的缓冲区内使用规范差异植被指数 (NDVI) 量化了住宅绿地.
主要成果:
- 抑郁症的患病率从大流行前到大流行期间几乎翻了一番 (男性:8.5%至16.5%;女性:14.4%至27.1%).
- 较高的住宅绿色 (NDVI) 与大流行期间抑郁的几率显著降低 (OR=0.91对于非抑郁的流行前).
- 绿色的保护作用在社会经济地位较低的人群中最为明显.
结论:
- 城市绿地可以作为对抑郁症的保护因素,特别是在COVID-19流行病等公共卫生危机期间.

Long-term Depression
2.6K
Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.

Chronic stress profoundly affects mental health, significantly influencing mood, behavior, and overall quality of life. Research closely links chronic stress with mental health conditions such as depression, anxiety, and substance use disorders. Ongoing exposure to stress can lead to physiological and psychological changes, initiating a cycle of emotional distress and maladaptive coping mechanisms.

Cognitive Development During Adulthood
267
Cognitive development continues throughout adulthood, undergoing significant shifts across early, middle, and late stages. Individual transition occurs from adolescent idealism to pragmatic and adaptable thinking in early adulthood. During this period, individuals learn to integrate personal beliefs with the recognition that other perspectives are equally valid. Exposure to the complexities of modern society, diverse experiences, and higher education contribute to this adaptive thought process,...

Depressive Disorders: MDD and Dysthymia
212
Depressive disorders are a group of mental health conditions characterized by pervasive feelings of sadness, diminished pleasure in life, and a significant impact on daily functioning. These conditions are most prevalent in individuals during their 30s and affect women at twice the rate of men. Contrary to popular belief, younger individuals are generally more susceptible to these disorders than older adults. Two key types of depressive disorders include Major Depressive Disorder (MDD) and...
