A Study of United States Registered Dietitian Nutritionists during COVID-19: From Impact to Adaptation.

The COVID-19 pandemic introduced an unprecedented health crisis, requiring many Registered Dietitian Nutritionists (RDNs) to expand their duties and services, while other RDNs faced unemployment, reduced hours, and changes to their work environment. This study evaluated whether the pandemic impacted RDNs' weight, eating behaviors, and psychological factors, and whether professional training as an RDN was perceived as a protective factor in maintaining healthy habits. A 57-item, cross-sectional, online questionnaire including open-ended questions was distributed to RDNs residing in the United States. Over two months (January 2021 to February 2021), 477 RDNs completed the questionnaire. Among RDNs, 68.5% reported no weight change, 21.4% reported weight gain greater than 5 pounds, and 10.3% reported weight loss greater than 5 pounds. Approximately 75% (n = 360) reported their RDN professional training equipped them with the skills needed to maintain healthy eating behaviors. Reduced physical activity and mental health were the top qualitative themes that emerged regarding reasons for weight change. These findings suggest that RDN professional practice skills may have conferred some personal health benefits, as evidenced by smaller weight gains, the maintenance of healthy habits, and fewer reporting psychological effects relative to the general population and other health professionals, thereby limiting the impact of pandemic-induced work and life disruptions.
