Obesity, lifestyle behaviours and psychological effects of the COVID-19 lockdown: A survey of patients attending a tertiary weight loss clinic.

Lockdown measures due to coronavirus-19 disease (COVID-19) have impacted lifestyle factors. This study aimed to explore whether health and lifestyle behaviours changed during the 2020 COVID-19 lockdown among patients with obesity. A specifically designed online survey and the Depression Anxiety Stress Scale (DASS-21) were administered to patients scheduled to attend a tertiary weight management service between 6 June-12 August 2020. A total of 210 participants completed the survey; mean age (SD) was 52.1 (12.5) years, 69% female and 67% Caucasian. Only 1.4% had tested positive to COVID-19. There was a statistically significant increase in weight pre- and post-COVID-19 lockdown, with no sex differences. Most (61.3%) gained weight, 30.4% lost weight and 8.3% maintained. The majority changed their overall purchasing (88.4%) and eating behaviours (91.6%). Two-thirds (64%) reported they did some form of exercise during the lockdown. Of those, exercise declined in 56.8% and increased in 18%. DASS-21 scores were positively correlated to worry about COVID-19, eating fewer core foods and eating more convenient/treat foods and negatively correlated with exercise. The results provide insights into how and why behaviour change occurs during stressful periods like the COVID-19 pandemic. Although there was variability in individual weight trajectories, on average people with obesity gained weight and changed lifestyle behaviours during the COVID-19 lockdown period. Strategies and support for people with obesity are required at these times.
