每天几杯咖啡是否有助于缓解抑郁1

Causes of death were tracked during the study period by reviewing death certificates; 277 deaths were the result of suicide.

对于研究期间发生的死亡案例，研究人员会查看死亡证明书以追踪死因；277例死亡源于自杀。

The analysis showed that the risk of suicide among adults drinking 2-4 cups of coffee (the equivalent of about 400 mg of caffeine) a day was 50% less than the risk for adults who drank decaffeinated coffee or one cup or less of caffeinated coffee. Drinking more than 4 cups of coffee didn’t drop the suicide risk lower.

分析显示，每天饮用2-4杯咖啡（相当于约400毫克咖啡因）的成年人中，自杀的风险比饮用脱咖啡因咖啡或一杯以下含咖啡因咖啡的成年人低50%。每天饮用四杯以上咖啡并未进一步降低自杀风险。

As with all correlative results, it’s worth noting that this analysis does not show causation between drinking coffee and lower suicide risk, and there’s nothing in this study to suggest that suddenly bumping up your caffeine intake will curb depression. It’s also worth noting that the three studies examined in this one were cohort studies, meaning they tracked multiple health risk factors across large groups over the course of several years, and it’s notoriously difficult to control for variables with this study design. Cohort study results aren’t very popular with statisticians.
