This study aimed to determine the occurrence and risk factors for persistent symptoms after mild to moderate severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in patients who presented in primary care during the 2021 pandemic. A retrospective cross-sectional survey was conducted in six public family health care units in Joao Pessoa, Brazil. A questionnaire with a set of 18 validated clinical outcomes was used to assess prolonged symptoms beyond 3 months of duration in 226 adults who had confirmed SARS-CoV-2 infection. Binary logistic regression models were used to estimate adjusted odds ratios (aOR) and risk factors for Long COVID. A total of 16 outcomes were significantly associated with Long COVID. The largest aOR were estimated for short-term memory loss, anxiety, and loss of attention. The risk factors for Long COVID included ≥ 5 symptoms (15.82, 7.33-34.15, p < 0.0001), female sex (aOR: 1.91, 95% CI: 1.03-3.53, p = 0.032), age 40-49 years (3.45, 1.14-10.51, p = 0.029), and age 70+ years (4.0, 1.01-15.51, p = 0.045). Findings highlight a high frequency of persistent symptoms in adults who initially had non-severe SARS-CoV-2 infection, who are predominantly of working age, and who did not present multiple comorbidities. This study supports the need for assessing clinical outcomes and risk factors on Long COVID in primary care using routinely recorded clinical outcomes.
本研究旨在确定2021年大流行期间在初级保健机构就诊的轻度至中度严重急性呼吸综合征冠状病毒2（SARS-CoV-2）感染患者持续症状的发生率及风险因素。在巴西若昂佩索阿的六个公共家庭医疗保健单位进行了一项回顾性横断面调查。使用一份包含18项经过验证的临床结果的问卷，对226名确诊感染SARS-CoV-2的成年人持续3个月以上的症状进行评估。采用二元逻辑回归模型估计新冠长期症状的调整比值比（aOR）和风险因素。共有16项结果与新冠长期症状显著相关。短期记忆丧失、焦虑和注意力不集中的aOR估计值最高。新冠长期症状的风险因素包括≥5种症状（15.82，7.33 - 34.15，p < 0.0001）、女性（aOR：1.91，95%CI：1.03 - 3.53，p = 0.032）、40 - 49岁（3.45，1.14 - 10.51，p = 0.029）以及70岁及以上（4.0，1.01 - 15.51，p = 0.045）。研究结果凸显了最初感染非重症SARS-CoV-2、主要为工作年龄且无多种合并症的成年人中持续症状的高发生率。本研究支持在初级保健中使用常规记录的临床结果评估新冠长期症状的临床结果和风险因素的必要性。
