背景以前的研究已经将骑自行车与改善心理健康联系起来，但这些研究倾向于使用样本量小和自我报告的健康措施的横断面调查数据，并且可能容易受到遗漏变量偏差和反向因果关系的影响。我们使用工具变量方法和从关联的行政数据中获取的心理疾病的客观衡量标准来问：“骑自行车上下班是否降低了心理疾病的风险？”方法我们的研究链接数据在爱丁堡和格拉斯哥从苏格兰人口普查与精神健康处方从国家卫生服务处方信息系统的记录。我们使用的道路距离从家到最近的自行车道作为一个工具变量为cyclecommuting.ResultsIn总，378 253人年龄在16-74岁的生活和工作在爱丁堡市和格拉斯哥市理事会地区在2011年人口普查被列入我们的研究; 1.85%的通勤者在格拉斯哥和4.8%的通勤者在爱丁堡骑自行车上班。 在骑自行车的人中，9%的人有心理健康处方，而非骑自行车的人只有14%。使用双变量probit模型，我们估计在人口普查后的5年内，抗抑郁药和/或抗焦虑药处方的平均平均减少率为-15.1%（95%置信区间：-15.3%至-15.0%）之间的周期通勤者相比，那些谁使用任何其他模式commut.ConclusionsThis工作表明，周期通勤是因果关系，以减少精神疾病。该报告还提供了进一步的证据，支持促进积极出行，以鼓励距离较短的通勤者改为骑自行车通勤。
BackgroundPrevious studies have linked cycling with improved mental wellbeing but these studies tend to use cross-sectional survey data that have small sample sizes and self-reported health measures, and are potentially susceptible to omitted-variable bias and reverse causation. We use an instrumental variable approach and an objective measure of mental ill-health taken from linked administrative data to ask: ‘Does cycle commuting reduce the risk of mental ill-health?’MethodsOur study links data on commuting in Edinburgh and Glasgow from the Scottish population census with mental health prescriptions from the National Health Service Prescribing Information System records. We use road distance from home to nearest cycle path as an instrumental variable for cycle commuting.ResultsIn total, 378 253 people aged 16–74 years living and working in the City of Edinburgh and Glasgow City council areas at the 2011 census were included in our study; 1.85% of commuters in Glasgow and 4.8% of commuters in Edinburgh cycled to work. Amongst cyclists, 9% had a prescription for mental health compared with 14% amongst non-cyclists. Using a bivariate probit model, we estimate a mean average reduction in prescriptions for antidepressants and/or anxiolytics in the 5 years following the census of –15.1% (95% CI: –15.3% to –15.0%) amongst cycle commuters compared with those who use any other mode to commute.ConclusionsThis work suggests that cycle commuting is causally related to reduced mental ill-health and provides further evidence in support of the promotion of active travel to encourage commuters travelling shorter distances to shift to cycle commutes.
