这项研究发现,精神分裂症和严重抑郁症在遗传上增加了跌倒的风险. 吸烟开始部分调解了这种因果关系,突出了预防跌倒的潜在干预目标.
科学领域:
- 精神病学遗传学 精神病学遗传学
- 流行病学 流行病学
- 老年学是指老年学的学科.
背景情况:
- 精神疾病与增加跌倒风险之间的因果关系尚未得到充分证实.
- 这项研究探讨了常见的精神疾病和跌倒风险之间的关系的遗传基础.
研究的目的:
- 探索遗传决定性精神分裂症 (SCZ),主要抑郁症 (MDD) 和阿尔茨海默病 (AD) 之间的因果关系,以及使用孟德尔随机化 (MR) 的跌倒风险.
主要方法:
- 利用全基因组关联研究 (GWAS) 对SCZ,MDD,AD和跌倒风险的数据.
- 采用单变量和多变量门德尔随机化 (MR) 分析,包括反变量加权 (IVW).
- 进行了敏感性分析和调解MR,以评估因果关系并确定像吸烟开始这样的调解因素.
主要成果:
- 精神分裂症 (SCZ) 和严重抑郁症 (MDD) 显示出与跌风险增加的显著积极因果关系.
- 多变量MR证实了SCZ,MDD和跌倒风险之间的持续联系,即使调整了BMI和吸烟开始.
- 吸烟的开始被确定为SCZ和MDD对跌倒风险的因果作用的部分调解者.
结论:
- 提供了强有力的遗传证据,支持SCZ和MDD之间的因果关系以及较高的跌倒风险.
- 强调医疗保健提供者需要识别和管理SCZ和MDD患者的跌倒风险.
- 建议戒烟干预措施可能有助于减轻患有这些精神疾病的人的跌倒风险.
