The Ariel University Survey on Dietary Changes and Anxiety During the Coronavirus Pandemic

The study will leverage the COVID-19 pandemic to study associations between dietary patterns, weight changes and anxiety. The study utilizes an online survey, publicized on public and personal social media pages, to query demographics, dietary and exercise patterns and measures of anxiety. Dietary patterns are assessed using the Mediterranean Diet Score, which evaluates the similarity between reported dietary intake and the Mediterranen Diet Pattern, which has been shown to reduce all-cause mortality and cardiovascular morbidity and mortality. Changes in dietary patterns and duration of exercise during vs. prior to the pandemic are measured. Anxiety is measured using the General Anxiety Disorder (GAD)-7 scale. Additional measures of social isolation, both prior to and during the pandemic, are queried in the survey. Data are anonymous and investigators have no ability to associated the response to an individual or IP address. However, interested respondents can provide an email address to which an analysis of the diet score can be sent. Data are automatically downloaded to an Excel spreadsheet, and this is cleaned and uploaded to SPSS for analysis. Continuous data are assessed for normality using the Kolmogorov-Smirnov test and will be summarized using median (IQ range) or mean (sd) as appropriate. Nominal data will be summarized in frequency tables and presented as n (%). Associations between the total Mediterranean Diet Score and the GAD-7 will be described by calculating the Pearson's or Spearman's correlation coefficient as appropriate. Before vs. after responses will be evaluated using the Wilcoxon Signed Ranks Test or the McNemar Test. Differences in responses by demographic characteristics will be measured using the t-test for independent samples, the Mann-Whitney U or ANOVA as appropriate. The GAD-7 score will be dichotomized to moderate anxiety or more (GAD-7=10) vs. lower, and modeled using logistic regression analyisis. The survey format permits real time response to the ongoing pandemic and the multi-lingual presentation allows for a wide potential population of respondents who can reply in a language in which they are comfortable. Further, this permits by-language comparisons.
