A validated questionnaire was filled in by parents. Snoring was reported as never, occasional (<once/wk), frequent (1-4 times/wk), or constant (5-7 times/wk).Results: Children enrolled were 194 [median (range) age 5.2 (4.5-7.0) yr, GA 28.1 (23-31) wk]. Rint was performed by 193 children, Rrs8 and Xrs8 by 185. Mean (SD) results by snoring group are reported in the table.View this table:No difference was found in Rint, Rrs8 or Xrs8 among the first 3 categories of snoring. When comparing those who snored constantly to the other categories grouped together Rint was borderline higher (1.01 vs 0.89 kPa.L-1.s; p=0.062) and Rrs8 was significantly increased (9.16 vs 8.14 hPa.L-1.s; p 0.032), while no difference was found for Xrs8 (-3.00 vs -2.59 hPa.L-1.s; p= 0.191).Conclusion: Children born very preterm with constant snoring have increased respiratory resistance that can be detected at preschool age using feasible techniques.
