RESUMO
Introduction: It could be beneficial to accelerate the hospitalization of patients with the identified clinical risk factors of intensive care unit (ICU) admission, in order to control and reduce COVID-19-related mortality. This study aimed to determine the clinical risk factors associated with ICU hospitalization of COVID-19 patients. Methods: The current research was a cross-sectional study. The study recruited 7182 patients who had positive PCR tests between February 23, 2020, and September 7, 2021 and were admitted to Afzalipour Hospital in Kerman, Iran, for at least 24 hours. Their demographic characteristics, underlying diseases, and clinical parameters were collected. In order to analyze the relationship between the studied variables and ICU admission, multiple logistic regression model, classification tree, and support vector machine were used. Results: It was found that 14.7 percent (1056 patients) of the study participants were admitted to ICU. The patients' average age was 51.25±21 years, and 52.8% of them were male. In the study, some factors such as decreasing oxygen saturation level (OR=0.954, 95%CI: 0.944-0.964), age (OR=1.007, 95%CI: 1.004-1.011), respiratory distress (OR=1.658, 95%CI: 1.410-1.951), reduced level of consciousness (OR=2.487, 95%CI: 1.721-3.596), hypertension (OR=1.249, 95%CI: 1.042-1.496), chronic pulmonary disease (OR=1.250, 95%CI: 1.006-1.554), heart diseases (OR=1.250, 95%CI: 1.009-1.548), chronic kidney disease (OR=1.515, 95%CI: 1.111-2.066), cancer (OR=1.682, 95%CI: 1.130-2.505), seizures (OR=3.428, 95%CI: 1.615-7.274), and gender (OR=1.179, 95%CI: 1.028-1.352) were found to significantly affect ICU admissions. Conclusions: As evidenced by the obtained results, blood oxygen saturation level, the patient's age, and their level of consciousness are crucial for ICU admission.
RESUMO
BACKGROUND: Because of high prevalence of coronary artery diseases (CADs) in Iran and their relationship with low physical activity (LPA), this study aimed to measure the epidemic size of LPA, its incidence rate, and its relationship with other CAD risk factors in Kerman, Iran. METHODS: About 10,000 adults were randomly recruited through single-stage cluster sampling. Demographic characteristics, biochemical variables, smoking, opium use, mental status, and physical activities were assessed. The relationship between LPA and 7 other CAD risk factors was measured. Five-year incidence rate of LPA was calculated according to the data from the physically active participants in the first phase of the study (n = 3416) who attended the second phase after 5 years. RESULTS: The prevalence of low, moderate, and intense physical activity was 47.2%, 34.8%, and 18.0%, respectively. LPA rose from 45.1% to 62.2% after the age of 25 years. Women had higher LPA than men. Participants with LPA had significantly higher chance of cigarette smoking, diabetes, overweight/obesity, hypertension, and opium addiction. Five-year incidence rate of LPA was 5.1 persons/100 person-years among physically active population. CONCLUSION: Almost half of the studied population suffering from LPA was at risk of CAD. Such risky lifestyle pattern while worsened in the last 5 years makes the emerging of CAD epidemic unavoidable, if appropriate timely interventions not being in place accordingly.
