Abstract

OBJECTIVE: We investigated whether micronutrients given acutely following the Christchurch earthquakes continued to confer benefit 1 year following the treatment. METHODS: Sixty-four adults from the original 91 participants experiencing heightened anxiety or stress 2-3 months following the 22nd February 2011 earthquake and who had been randomized to receive three different doses of micronutrients completed on-line questionnaires assessing mood, anxiety, stress, and symptoms associated with post-traumatic stress disorder 1 year after completing the initial study. Twenty-one out of 29 nonrandomized controls who did not receive the treatment also completed the questionnaires. RESULTS: Both the treated and control groups experienced significant improvement in psychological functioning compared with end-of-trial. However, treated participants had better long-term outcomes on most measures compared with controls (ES = 0.69-1.31). Those who stayed on micronutrients through to follow-up or stopped all treatment reported better psychological functioning than those who switched to other treatments including medications. About 10% of the sample continued to have post-traumatic stress disorder symptoms. CONCLUSIONS: Disaster survivors improve psychologically over time regardless of receiving intervention; however, those taking micronutrients during the acute phase following a disaster show better outcomes, identifying micronutrients as a viable treatment for acute stress following a natural disaster with maintenance of benefits 1 year later.
