Anthropometric and cardiopulmonary parameters in Bulgarian and Romany children: cross-sectional study.

AIM: To examine anthropometric parameters and cardiopulmonary function in Bulgarian and Romany children. METHODS: Two hundred and ten healthy children (153 Bulgarian and 57 Romany) of similar age (10.5-/+0.5 years, mean-/+standard deviation) underwent an anthropometric and pulmonary function assessment and performed an exercise test on a treadmill, using the modified Balke protocol. RESULTS: Bulgarian children were significantly taller (145-/+7 vs 142-/+7 cm) and heavier (39-/+9 vs 35-/+8 kg) than Romany children. They also had more body fat (20.5-/+8.1% vs 17.8-/+7.6% in Romanies). In a subset of the whole sample, it was established that Bulgarian children had significantly higher birth weight in comparison with Romanies (3,358-/+513 vs 3,095-/+435 g; P=0.006). Mean absolute values of vital capacity (VC), forced expiratory volume in 1 s (FEV(1)) and transfer factor (T(L,CO)) were lower for Romany than for Bulgarian children, 7.8%, 7.3%, and 10.2%, respectively. The data from the incremental treadmill test showed that peak oxygen uptake (VO(2)peak) did not differ significantly between the two ethnic groups (1,341-/+293 vs 1,260-/+280 mL/min). The level of physical exertion was almost the same in the studied groups (respiratory exchange ratio (RER)=1.08-/+0.08 vs 1.08-/+0.06), but the perception of exertion was higher in Bulgarian children (Borg score=4.9-/+1.5 vs 3.2-/+1.5; P<0.001). CONCLUSIONS: There are significant differences between Bulgarian and Romany children with regard to anthropometric parameters, including stature, lung function indices, and perception of exertion.
