Abstract
This study was undertaken to investigate and compare the sympathetic cardio vascular parameters in age matched overweight, underweight and normal weight school going boys in southern Odisha. 75 Boys between age group of 12-16 were subjected to study out of which 25 were overweight (BMI>25), next 25 were underweight(BMI<18.5),rest 25 were control group having normal BMI. Cold pressure test and hand grip dynamometer test were performed and blood pressure was measured during and after the tests as measures of cardiovascular parameter. Baseline SBP and MAP were significantly higher in overweight boys & lower in underweight boys. Maximum rise of SBP, DBP & MAP during hand grip dynamometer test were significantly higher in overweight boys & lower in underweight boys. Increase in SBP & MAP from their basal value during cold pressure test were significantly lower in overweight boys & higher in underweight boys. Thus it is concluded that both overweight & underweight boys have derangement of sympathetic cardiovascular function. SBP- Systolic blood pressure, DBP- Diastolic blood pressure , MAP- Mean arterial pressure
