Abstract:
Objective To discuss the relationship between body mass index(BMI)and flag_raising syncope ( PS)and micturition syncope(MS)in children and adolescents. Methods One hundred and six children and adoles_cents with PS or MS diagnosed at the Department of Dediatric Cardiovasology,Childrenˊs Medical Center,the Second Xiangya Hospital,Central South University from January 2003 to September 2017 were studied,including 51 males and 55 females,and their ages ranged from 5 to 18 years. There were 63 cases in the PS group(21 males and 42 females) and 43 cases in the MS group(30 males and 13 females). One hundred healthy children and adolescents including 50 males and 50 females who had routine healthy examinations at the hospital in the same period were selected as control subjects(healthy control group). Body length and body mass were measured,and BMI was calculated. Statistical inves_tigations were conducted with SDSS 22. 0 software. Results (1)The body mass and BMI in the PS group were lower than those in the MS group[(36. 33 ± 9. 85)kg vs.(42. 85 ± 12. 44)kg;(16. 56 ± 2. 41)kg∕m2 vs.(18. 48 ± 3. 04) kg∕m2],and the differences were statistically significant(F﹦7. 529,12. 411,all P〈0. 05). There was no difference in body length among the PS group,the MS group and the healthy control group[(146. 62 ± 12. 89)cm vs.(150. 79 ± 12. 78)cm vs.( 149. 75 ± 16. 02 )cm,F ﹦1. 314,P 〉0. 05 ]. No differences were found in age,frequency,body length,body mass and BMI between the PS syncope group and the MS group with different genders(all P〉0. 05).(2) The number of BMI_underweight children increased in the PS group(82. 53%,52∕63 cases)compared with that of the MS group(58. 14%,25∕43 cases)and that of the healthy control group( 52. 00%,52∕100 cases),and the difference was statistically significant(χ2 ﹦14. 556,P〈0. 01).(3)The positive rate by head_up tilt test(HUTT)was 72. 64%(77∕104 cases),and HUTT of the PS group was higher than that of the MS group[82. 53%(52∕63 cases)vs. 58. 14%(25∕43 cases)],and there was a significant difference statistically(χ2 ﹦7. 656,P〈0. 01). Conclusions Low BMI is prone to PS in children and adolescents.
