ABSTRACT

<p><b>OBJECTIVE</b>To identify methods in reducing the prevalence of lactose intolerance in children.</p><p><b>METHODS</b>A hydrogen respiration test (HRT) method was used in screening lactose intolerance (LI) subjects after taking 25 g of lactose among 106 children aged from 10 to 11 years old in a primary school located in the suburban area of Beijing. A cross-design was used to detect the effects of low lactose milk, yogurt and cereal-effect among 68 selected LI children.</p><p><b>RESULTS</b>The incidence of LI was 80.2% after the children took 25 g of lactose, and after taking a 250 ml of full milk, lactase-fermented milk, coinfected milk, yogurt, or milk with meal, the LI incidences were 21.1% (12/57), 0% (0/25), 6.1% (2/33), 8.6% (3/35) and 13.6% (3/22) respectively.</p><p><b>CONCLUSION</b>Low lactose milks and yogurt could reduce the LI incidence among LI children significantly.</p>
