To estimate quantitatively (the aetiological fraction) the impact of poor social network on premature death from cardiovascular disease in middle aged, white men.
The causality of the relationship has already been discussed in a large review, and it is assumed to be well documented. The numerical estimation of the impact was based on a review of all published cohort studies on the relationship between social network and mortality in white, middle aged men.
The studies reviewed are all of high epidemiological quality and present a consistent and stable dose-response pattern. The aetiological fraction was estimated to be 30%, with a plausible range of 20-40%.
Social network was an important, independent, risk factor for cardiovascular disease in white, middle aged men. It had a strong impact on mortality, comparable to that of traditional risk factors. Social network should have a more central role in future epidemiological research into cardiovascular disease. The factors that result in a strong social network should be identified and strategies applicable in preventive work should be developed.
定量评估(病因分数)不良社交网络对中年白人男性心血管疾病过早死亡的影响。
该关系的因果性已在一篇大型综述中讨论过,且假定有充分记录。影响的数值估计基于对所有已发表的关于社交网络与白人中年男性死亡率关系的队列研究的综述。
所综述的研究均具有较高的流行病学质量,并呈现出一致且稳定的剂量反应模式。病因分数估计为30%,合理范围为20%-40%。
社交网络是白人中年男性心血管疾病的一个重要、独立的风险因素。它对死亡率有很强的影响,与传统风险因素相当。社交网络在未来心血管疾病的流行病学研究中应发挥更核心的作用。应确定导致强大社交网络的因素,并制定适用于预防工作的策略。
