Abstract

Objectives

To compare the hydration status between children with obesity and normal-weighted children and to determine whether obesity is related to less water consumption.

Methods

Children aged between 7 and 18 years with obesity (Group 1, n=31) were compared with nonobese healthy volunteers (Group 2, n=30) in terms of body composition analysis, urine density and daily fluid intake.

Results

The fluid intake per body surface of Group 1 was found significantly less than Group 2 (p<0.001). The urine density was found significantly higher in Group 1 (1020 (10) vs. 1015(10), p<0.001). Subjects in Group 1 had a higher percentage of body fat (p<0.001), lower percentages of total body water and fat-free mass (p=0.007 and <0.001, respectively). While 55% of subjects in Group 1 satisfied the recommended daily fluid intake, this was 80% in Group 2 (p=0.036). The consumption of SSBs was 71% in Group 1 and 20% in Group 2, with higher amount in Group 1 (median 200 vs. 0 mL, p<0.001).

Conclusions

Children with obesity had less fluid consumption, lower TBW percentages and higher urine density. The results of this cross-sectional study showed that children with obesity were less hydrated than normal weighted children.
