Key result
Sitting height measures were positively associated with body mass index (p<0.001) and blood pressure in children, though the blood pressure association was dependent on BMI.
Why the study?

Are sitting-height measures associated with body mass index and blood pressure levels in children?
Sitting height is strongly associated with BMI and blood pressure in children, though the relationship with blood pressure is likely mediated by BMI.
SH measures link to BMI and BP in children but not independently of obesity; leaves open whether proportions add CV risk value beyond adiposity.
OBJECTIVE: Sitting height (SH) is an important parameter in the evaluation of children with growth and pubertal disorders. Besides this, it has been viewed as a biomarker of cardiovascular risk, which is increased in adults with relatively short legs. So, the aim of this study was to evaluate the relationship between body proportions and cardiovascular risk markers in children. SUBJECTS AND METHODS: Eight hundred and seventeen children aged 6-13 years were evaluated. Weight, height, sitting-height (SH), sitting-height/height (SH/H), body mass index (BMI) and blood pressure (BP) were assessed and converted to standard deviation scores (SDS) for age and sex. Statistical analyses were performed. RESULTS: There was a positive association of BMI SDS with SH and SH/H SDS (p<0.001). Overweight children showed SH 0.8 SDS superior to eutrophic children (p<0.001). SH SDS was also directly related to BP SDS, but this association was not independent of the association between obesity and BP when assessed by multiple regression analyzes. CONCLUSION: Measures of SH are strongly associated with BMI and BP in children, although the association between SH and BP is probably dependent on the association of both those variables with BMI. This is (an) important information for correct interpretation of SH values in children.

Marcato et al. (2014) reported a cross-sectional. Sitting height (SH) and sitting-height/height (SH/H) ratio was evaluated on Body mass index (BMI) SDS and blood pressure (BP) SDS (p=<0.001). Sitting height measures were positively associated with body mass index (p<0.001) and blood pressure in children, though the blood pressure association was dependent on BMI.
