We studied the association of lactose intolerance with growth in children.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>In this prospective case\u2013control study, we compared Caucasian prepubertal children with lactose intolerance (LI) [<jats:italic>n<\/jats:italic>\u2009=\u200930, median age\u2009=\u20097.87 years (3.00\u201312.75)] to healthy controls [(<jats:italic>n<\/jats:italic>\u2009=\u200975, median age\u2009=\u20092.25 years (2.00\u20137.25)]. A lactose tolerance test was performed for lactose intolerance diagnosis. The gastrointestinal symptom score was administered at baseline and after a lactose-free diet for a median period of 9.0 months [range 5%\u201395% (6.0\u201324.0)]. The anthropometric parameters were measured at baseline and follow-up. All the anthropometric data were converted into standard deviation scores (SDS).

Nonetheless, due to the small sample size, the results on the anthropometric profile of the LI group require careful interpretation.
