Summary
Infant feeding practices and family factors are linked to atopic illness in Hong Kong toddlers. Maternal antibiotic use and later mixed feeding increased atopy risk, while exclusive breastfeeding showed a protective association.
Area of Science:
- Pediatrics
- Immunology
- Public Health
Background:
- Atopic illnesses, such as eczema and allergies, are common in early childhood.
- Understanding the influence of infant feeding and family factors on atopy development is crucial for prevention strategies.
Purpose of the Study:
- To investigate the association between infant feeding methods, family, and environmental factors with atopic illness in Hong Kong toddlers.
- To identify risk and protective factors for atopy in early childhood.
Main Methods:
- A case-control study design was employed.
- 206 toddlers aged 4 months to 3 years in Hong Kong were recruited.
- Binary logistic regression analysis was used to determine associations.
Main Results:
- Atopy was associated with male gender (OR 2.072), maternal antibiotic use (OR 2.276), delayed mixed feeding (OR 2.497), and exclusive breastfeeding for 3 months (OR 1.972).
- Maternal history of eczema significantly increased the risk of atopy in toddlers (OR 4.510).
Conclusions:
- Infant feeding practices, maternal health, and family history are significant factors in toddler atopy.
- While exclusive breastfeeding shows a protective effect, further research into breast milk's nutritional components is recommended.

3.8K
Asthma is a chronic respiratory ailment that requires careful management due to its varying symptoms and influencing factors. It is characterized by airway inflammation, bronchial hyperresponsiveness, and reversible airflow obstruction, leading to symptoms like wheezing, shortness of breath, chest tightness, and coughing. The symptom frequency and intensity may vary considerably over time. It is also linked to immune system responses to allergens and irritants, highlighting the complex...

Asthma is a prevalent chronic respiratory condition marked by inflammation and hyperresponsiveness of the airways. Its pathophysiology involves complex interactions among inflammatory pathways, immune responses, and neural mechanisms.
Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
Critical processes in asthma pathophysiology include:

Asthma is a chronic pulmonary condition involving inflammation of the airways, hyper-reactivity, and reversible obstruction of the airways. This condition can significantly impact a person's quality of life, making breathing difficult and leading to distressing symptoms.
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
