【摘要】 [目的]本研究旨在阐明2022年12月中国实施动态清零政策后，新型冠状病毒感染（COVID-19）康复者的短期症状、持续时间及其影响因素。[方法]采用2023年1月14日至2月1日在中国开展的大规模线上调查数据。研究对象涵盖所有年龄段人群。通过卡方检验和多因素逻辑回归分析确定不同症状的相关影响因素。[结果]研究共纳入来自中国七大区域的21,012名患者（女性占71.22%）。多数患者从症状出现到核酸检测转阴的时间≤10天（72.33%）。症状分布随时间变化呈现差异，其中呼吸系统症状（1-4周）和心理-心脏症状（5-8周）最为常见。多因素分析显示，男性、无合并症、居住于东北和西北地区（与华中地区相比）是症状发生风险降低的独立影响因素，而41-60岁年龄组（与18-40岁相比）可能是潜在风险因素。[结论]COVID-19康复后最常见的短期症状为呼吸系统症状和心理-心脏症状。性别、年龄、地理区域和合并症是短期症状发生的潜在影响因素。更多还原

【Abstract】 Objectives: This study aimed to clarify the short-term symptoms, duration, and influencing factors in people recovering from coronavirus disease 2019(COVID-19) after China’s dynamic zero-COVID-19 policy was implemented in December 2022.Methods: We included data from a large-scale on-line survey conducted in China between January 14 and February 1, 2023. Participants were individuals of all ages. Chi-squared tests and multivariate logistic regression analyses were performed to identify factors associated with different symptoms.Results: Overall, 21,012 patients from seven regions of China were included in this study(female: 71.22%). For most patients, the period from symptom onset to a negative nucleic acid test result was ≤10 days(72.33%). The distribution of symptoms varied at different times, with respiratory(1–4 weeks) and psychocardiology(5–8 weeks) symptoms being the most common. Multivariate analysis identified male sex, no comorbidity, and living in northeast and northwest China(compared with central China) as independent factors associated with a lower risk of symptoms, while age(41–60 years) was a possible risk factor(compared with 18–40 years).Conclusions: Short-term respiratory and psychocardiology symptoms were the most common after COVID-19 recovery. Sex, age, geographical region, and comorbidities were potential influencing factors for the development of short-term symptoms.更多还原
