Preprints with The Lancet is part of SSRN´s First Look, a place where journals identify content of interest prior to publication. Authors have opted in at submission to The Lancet family of journals to post their preprints on Preprints with The Lancet. The usual SSRN checks and a Lancet-specific check for appropriateness and transparency have been applied. Preprints available here are not Lancet publications or necessarily under review with a Lancet journal. These preprints are early stage research papers that have not been peer-reviewed. The findings should not be used for clinical or public health decision making and should not be presented to a lay audience without highlighting that they are preliminary and have not been peer-reviewed.

Background: The pandemic of 2019 novel coronavirus (COVID-19) poses a challenge to health promotion in the days of lockdown. We aimed to evaluate the characteristics of lifestyle in China during the initial stage of COVID-19 lock down.
Methods: The questionnaire was distributed to Chinese adults living in 31 provinces of China via internet using a snowball sampling strategy. Information on 7-day physical activity recall, sedentary screen time, and emotional state were collected between January 24 and February 2, 2020. ANOVA, χ² test, and spearman’s correlation coefficient were used for statistical analysis.
Findings: 12107 participants aged 18-80 years old were included. During the initial phase of COVID-19 outbreak, nearly 60% of Chinese adults had inadequate physical activity (95% CI 56.6%-58.3%), which was more than twice the global prevalence (27·5%, 25·0–32·2%). Their mean screen time was more than 4 hours per day during home stay (261·3 ± 189·8 minutes per day). Of all participants, the positive affect score was 24·78 and the negative affect score was 19·34. In addition, we found that the proportions of confirmed COVID-9 cases were positively and significantly correlated with provincial negative affect scores (r=0·501, p =0·004) but not correlated with the prevalence of insufficient physical activity, screen time, and positive scores ( p >0·05). Individuals with vigorous physical activity appeared to have better emotional state and less sedentary screen time than those with light physical activity.
Interpretation: During this nationwide lockdown, more than half of Chinese adults were temporarily living in a sedentary lifestyle with insufficient physical activity, more screen time, and poor emotion states, which may carry considerable health risks. Promotion of home-based self-exercise can potentially help improve health and wellness.
