Clean Home, Still Allergic? Nearly Half of Taiwan's Children Suffer Allergies! Taiwan Society for Immunology Calls on Parents to 'Prevent Early, Adjust Constitution'

"It's just that the child's skin is sensitive; it will naturally get better with age"—a reassuring phrase for many parents, but one that may cause children to miss the most critical window for allergy prevention. Physicians emphasize that atopic dermatitis (eczema) is not necessarily a temporary condition, but could be the starting point of the "Atopic March," which, once initiated, may lead to food allergies, allergic rhinitis, and even asthma. Allergy prevention should not wait for symptoms to appear. True proactive action means early intervention during the golden period before age three.

In response to World Allergy Day on July 8, the Taiwan Society of Allergy, Asthma & Clinical Immunology held a public education press conference ahead of the event. Fifth-term President Dr. Ou Liang-Hsiu and Fourth-term President Dr. Lu Ke-Huan analyzed Taiwan's pediatric allergy landscape, common parental misconceptions, and the latest international research. They urged parents to adopt a correct allergy prevention mindset of "early assessment, early intervention, and internal-external balance," ensuring children do not miss the critical early stage of immune system development.

Seize the First Three Years: Implement Evidence-Based Prevention Strategies

The Taiwan Society of Allergy, Asthma & Clinical Immunology highlights that, according to a recent large-scale cohort study involving over 2 million Taiwanese children [2], allergic rhinitis, asthma, and atopic dermatitis are major chronic diseases in children. The prevalence of allergic rhinitis is nearly 50%, asthma ranges from 20–30%, and atopic dermatitis exceeds 10%. Allergies are now highly prevalent among children, significantly impacting their quality of life and family caregiving. Pediatric allergies have become a national health concern.

Dr. Ou Liang-Hsiu, Fifth-term President, notes that in clinical practice, children often start with atopic dermatitis and progress to food allergies, allergic rhinitis, and eventually asthma—a phenomenon known as the "Atopic March." He emphasizes that recurring symptoms such as rashes, nighttime coughing, and morning sneezing are warning signs of allergies, potentially affecting sleep, concentration, growth, and learning. True proactive prevention requires seizing the golden 1,000-day window of immune system development from birth.

However, Dr. Ou also warns that postnatal care practices profoundly influence immune development: "Allergy prevention cannot be half-hearted." Beyond environmental control, proper nutritional care should be combined to form a comprehensive "internal-external" prevention strategy, reducing future allergy risks at the root.

Choosing Formula Based on Evidence: Pediatricians Stress Not All Hydrolyzed Formulas Are Equal

Many parents online ask: "Is drinking hydrolyzed formula enough?" or "Can goat milk also prevent allergies?" In response, Dr. Lu Ke-Huan, Fourth-term President, states that breast milk remains the top choice for infant nutrition and allergy prevention. Research [3] shows that certain clinically proven hydrolyzed formulas can reduce the risk of atopic dermatitis in high-risk infants. When exclusive breastfeeding is not possible, parents should choose accurately hydrolyzed formulas with clinical evidence. The key is not brand or milk source, but whether there is product-specific clinical research support. Regarding the popular goat milk, Dr. Lu clarifies that there is currently insufficient and inconsistent evidence for allergy prevention.

Dr. Lu further explains that not all "hydrolyzed" formulas offer allergy prevention benefits—differences in protein source, degree of hydrolysis, and peptide fragment size lead to varying effectiveness. The landmark German Infant Nutritional Intervention Study (GINI Study), which followed over 2,000 high-risk infants for 20 years, is one of the longest-running allergy prevention studies globally. It confirmed that a specific, precisely hydrolyzed formula reduced the cumulative incidence of atopic dermatitis/eczema by 41% and allergic rhinitis risk by 33% compared to standard cow’s milk formula, with a 56% lower asthma prevalence in adolescence.

Parents are advised to rely on product-specific evidence when selecting formulas. A complete prevention strategy must follow three principles: "early initiation," "internal-external balance," and "scientific evidence." Especially for high-risk infants with a family history of allergies, early consultation with a pediatrician is crucial if exclusive breastfeeding is not feasible. Given each baby’s unique constitution and risk profile, parents are encouraged to bring family allergy history to a pediatrician for personalized prevention planning.

Parent Self-Check: 50% of Allergic Children Come from Non-Allergic Families—Doctors Urge 'Prevention from Birth'

Even without parental allergies, children can still develop allergies. The Taiwan Society recommends parents use the "Family Allergy Score (FAS)" to assess their baby’s allergy risk based on family members’ allergy status. Pediatricians advise that every newborn needs proactive allergy prevention. Parents should seize the golden period before age three and consult pediatricians early to develop prevention strategies.

Dr. Ou Liang-Hsiu stresses that children are not miniature adults. From newborns to adolescence, immune function, physiology, and nutritional needs change continuously. Pediatric care goes beyond treating illness—it includes growth monitoring, vaccination, and allergy management. Given the high prevalence and chronic nature of pediatric allergies in Taiwan, the society urges that children under 18 prioritize consultation with pediatricians for early assessment and long-term follow-up, helping children build a healthy immune foundation from life’s start and grow up without allergies interrupting their development.
