Key result
Central adiposity in premenopausal obese women was associated with greater stress-related increases in diastolic blood pressure and total peripheral resistance compared to peripheral adiposity.
Why the study?
Does central adiposity compared to peripheral adiposity alter hemodynamic stress responses in premenopausal obese women?

Does central adiposity compared to peripheral adiposity alter hemodynamic stress responses in premenopausal obese women?
Central adiposity in premenopausal obese women is associated with enhanced vascular responses to stress, potentially increasing cardiovascular disease risk.

May signal elevated stress-related CVD vulnerability in central obesity; leaves open causality and requires prospective validation.
To examine the relationship between body fat distribution and hemodynamic stress responses, cardiovascular responses to a speech task and a forehead cold pressor task were evaluated with 24 premenopausal women classified a priori as either centrally or peripherally obese. Results showed that women with central adiposity exhibited greater stress-related increases in diastolic blood pressure and total peripheral resistance, whereas women with peripheral adiposity exhibited greater stress-related increases in cardiac output. Depression, self-consciousness, hostility, and mood scores did not explain significant variance in the stress response differences between regional adiposity groups. The findings suggest that central adiposity may increase the risk of cardiovascular disease in women at least in part by enhancing vascular responses to stress.

Davis et al. (1999) conducted a cross-sectional in Obesity (n=24). Central adiposity vs. Peripheral adiposity was evaluated on Cardiovascular responses to a speech task and a forehead cold pressor task. Central adiposity in premenopausal obese women was associated with greater stress-related increases in diastolic blood pressure and total peripheral resistance compared to peripheral adiposity.
