美國布列根和婦女醫院和哈佛醫學院JoAnn E. Manson聯合麻薩諸塞總醫院和哈佛醫學院Olivia I. Okereke團隊,研究了長期補充維生素D3與安慰劑相比對抑鬱或臨床相關抑鬱症狀風險以及情緒評分變化的影響。2020年8月4日,《美國醫學會雜誌》發表了該成果。
25-羥基維生素D水平較低與之後生活中抑鬱風險較高有關,但長期、大劑量的大規模試驗很少。
為了評估補充維生素D3對晚年抑鬱症風險和情緒評分的影響,研究組在美國一項針對25871名成年人的心血管疾病和癌症預防的隨機臨床試驗中進行了一項輔助試驗,2011年11月至2014年3月,招募了18353名50歲及以上的參與者,其中16657名有發生抑鬱症的風險,1696名有抑鬱症復發的風險(既往有抑鬱史,但過去兩年內無治療)。將其隨機分組,其中9181名每日口服維生素D3,9172名服用相匹配的安慰劑。
18353名參與者的平均年齡為67.5歲,女性佔49.2%,中位治療5.3年後,有90.5%的參與者完成了試驗。維生素D3組中有609例發生抑鬱症或臨床相關抑鬱症狀事件,發生率為每1000人年12.9例,安慰劑中有625例,發生率為每1000人年13.3例,兩組間抑鬱症發生率或復發率均無顯著差異。兩組間情緒評分隨時間的變化無明顯差異;8項患者健康問卷抑鬱量表(PHQ-8)得分均未改善。
總之,對於在基線檢查時沒有臨床相關抑鬱症狀的50歲及以上的成年人中,維生素D3治療與安慰劑相比,在中位5.3年的隨訪中,抑鬱症或臨床相關抑鬱症狀的發生率和復發率,以及情緒評分的變化,均未顯著改善。

Abstract: Importance Low levels of 25-hydroxyvitamin D have been associated with higher risk for depression later in life, but there have been few long-term, high-dose large-scale trials.
Objective To test the effects of vitamin D3 supplementation on late-life depression risk and mood scores.
Design, Setting, and Participants There were 18353 men and women aged 50 years or older in the VITAL-DEP (Vitamin D and Omega-3 Trial-Depression Endpoint Prevention) ancillary study to VITAL, a randomized clinical trial of cardiovascular disease and cancer prevention among 25871 adults in the US. There were 16657 at risk for incident depression (ie, no depression history) and 1696 at risk for recurrent depression (ie, depression history but no treatment for depression within the past 2 years). Randomization occurred from November 2011 through March 2014; randomized treatment ended on December 31, 2017, and this was the final date of follow-up.
Intervention Randomized assignment in a 2×2 factorial design to vitamin D3 (2000 IU/d of cholecalciferol) and fish oil or placebo; 9181 were randomized to vitamin D3 and 9172 were randomized to matching placebo.
Main Outcomes and Measures The primary outcomes were the risk of depression or clinically relevant depressive symptoms (total of incident and recurrent cases) and the mean difference in mood scores (8-item Patient Health Questionnaire depression scale [PHQ-8]; score range, 0 points [least symptoms] to 24 points [most symptoms]; the minimal clinically important difference for change in scores was 0.5 points).
Results Among the 18353 randomized participants (mean age, 67.5 [SD, 7.1] years; 49.2% women), the median treatment duration was 5.3 years and 90.5% completed the trial (93.5% among those alive at the end of the trial). Risk of depression or clinically relevant depressive symptoms was not significantly different between the vitamin D3 group (609 depression or clinically relevant depressive symptom events; 12.9/1000 person-years) and the placebo group (625 depression or clinically relevant depressive symptom events; 13.3/1000 person-years) (hazard ratio, 0.97 [95% CI, 0.87 to 1.09]; P=.62); there were no significant differences between groups in depression incidence or recurrence. No significant differences were observed between treatment groups for change in mood scores over time; mean change in PHQ-8 score was not significantly different from zero (mean difference for change in mood scores, 0.01 points [95% CI, 0.04 to 0.05 points]).
Conclusions and Relevance Among adults aged 50 years or older without clinically relevant depressive symptoms at baseline, treatment with vitamin D3 compared with placebo did not result in a statistically significant difference in the incidence and recurrence of depression or clinically relevant depressive symptoms or for change in mood scores over a median follow-up of 5.3 years. These findings do not support the use of vitamin D3 in adults to prevent depression.
