Insights
Obesity and contact with COVID-19 patients increase infection risk in children. Unlike adults, COVID-19 appears less severe in children, regardless of gender or comorbidities.
Area of Science:
- Pediatrics
- Infectious Diseases
- Epidemiology
Background:
- Comorbidities are known risk factors for severe COVID-19 in adults.
- The impact of comorbidities on COVID-19 susceptibility in children remains unclear.
Purpose of the Study:
- To investigate risk factors for COVID-19 susceptibility in children.
- To determine if specific comorbidities increase the risk of contracting COVID-19 in pediatric populations.
Main Methods:
- A case-control study was conducted in Mexico.
- Data collected included contact history, obesity, diabetes, hypertension, and immunosuppression.
Main Results:
- Contact with COVID-19 patients and obesity were significant risk factors for infection in the overall sample.
- These factors remained significant when analyzing boys and girls separately.
- No significant differences in disease severity (pneumonia, ICU admission, death) were observed between cases and controls in children.
Conclusions:
- Obesity is associated with increased susceptibility to COVID-19 in children, not just severe disease.
- COVID-19 appears to be less severe in children compared to adults.
- Further research is needed to understand the mechanisms linking obesity and COVID-19 in children.
Abstract:
Some comorbidities are risk factors for severe coronavirus disease (Covid-19) but it is unknown whether some increase susceptibility to Covid-19 in children. In this Mexican case-control study, contact with patients with Covid-19, or having obesity, or having diabetes, or hypertension or been immunosuppressed independently increased the risk for Covid-19 in the whole sample analysis. However, only contact history and obesity remained statistically significant in the separated analysis of girls and boys. The results suggest that obesity is not only associated with severe disease but also increases risk for Covid-19. Contrary to findings in adults, no difference between cases and controls was found for gender, presence of pneumonia or surrogates of severe disease including admission to intensive care unit, tracheal intubation or whether patient had died. This indicates that Covid-19 is less severe in children than adults. Future research is needed to establish the mechanisms involved in obesity and Covid-19 in children.

Medical History
Common Respiratory Disorders
Upper respiratory disorders impact the airways above the vocal cords, encompassing areas like the nose, sinuses, and throat. Various conditions fall under this category, including the common cold and allergic rhinitis. These disorders can stem from several causes,...

COPD: Pathogenesis and Clinical Features
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...
Chronic Obstructive Pulmonary Disease
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...
