There is emerging evidence that people affected by flooding suffer adverse impacts on their mental well-being, mostly based on self-reports.
We examined prescription records for drugs used in the management of common mental disorder among primary care practices located in the vicinity of recent large flood events in England, 2011-2014. A controlled interrupted time series analysis was conducted of the number of prescribing items for antidepressant drugs in the year before and after the flood onset. Pre-post changes were compared by distance of the practice from the inundated boundaries among 930 practices located within 10 km of a flood.
After control for deprivation and population density, there was an increase of 0.59% (95% CI 0.24 to 0.94) prescriptions in the postflood year among practices located within 1 km of a flood over and above the change observed in the furthest distance band. The increase was greater in more deprived areas.
This study suggests an increase in prescribed antidepressant drugs in the year after flooding in primary care practices close to recent major floods in England. The degree to which the increase is actually concentrated in those flooded can only be determined by more detailed linkage studies.
越来越多的证据表明，受洪水影响的人群心理健康受到不利影响，这大多基于自我报告。
我们研究了2011 - 2014年英格兰近期发生重大洪水事件附近的基层医疗实践中用于治疗常见精神障碍的药物处方记录。对洪水发生前后一年抗抑郁药物的处方数量进行了对照中断时间序列分析。在距离洪水淹没边界10公里内的930家医疗实践中，根据实践与淹没边界的距离比较前后变化。
在控制了贫困程度和人口密度后，距离洪水1公里内的医疗实践在洪水发生后的年份里，处方量比最远区域观察到的变化增加了0.59%（95%可信区间0.24至0.94）。在更贫困地区增加幅度更大。
本研究表明，在英格兰近期发生重大洪水后，靠近洪水区域的基层医疗实践中，抗抑郁药物的处方量在次年有所增加。实际增加量集中在受洪水影响人群中的程度，只能通过更详细的关联研究来确定。
