Abstract:

Objective

To investigate the impact of the 2019 novel coronavirus disease (COVID-19) pandemic on the willingness to change dietary habits among young adults in Shenzhen.

Methods

With an anonymous network sampling method, we conducted a questionnaire survey among 22,459 residents aged 15 to 45 years living in Shenzhen in March 2020. The questionnaire included socio-demographic information, subjective impact of the epidemic on individuals, and willingness to change dietary habits due to COVID-19. Multivariable linear regression model was used to analyzed the influencing factors of willingness to change dietary habits.

Results

Average age of the subjects was 27.9±7.8 years old. The mean score of willingness to change dietary habits was 2.17 (ranges from -9 to 9). Among them, the female, ≥35 years old people, with (bachelor degree or above education, married, non-medical staff, and with BMI of (18.5~23.9)kg/m2 had a good performance of the score, which were 2.84, 2.96, 2.52, 2.70, 2.19 and 2.34, respectively (P<0.05). Multivariate regression analysis showed that the impact of the COVID-19 pandemic (epidemic concern, impact of psychology, impact of work or study) are associated with a higher score of willingness to change dietary habits among female, the older, non-medical worker, and individuals married or with higher education level, normal BMI.

Conclusions

After experiencing the impact of COVID-19, there was a positive improvement on the willingness to adopt a proper diet among young adults in Shenzhen. We should strengthen the health education and promotion of reasonable diet. Individual subjective influence, gender, age, education level, occupation, marital status and BMI are the factors that influence the willingness.
