The current study was conducted to determine the effect of adiposity on vascular distensibility in Gujarati Indian adolescents as research indicating the pathogenesis of hypertension among overweight and/or obese Indian adolescents is scant and ethnic differences exist in the pathogenesis of hypertension
A cross-sectional study was conducted on 488 Gujarati Indian adolescents of 16-19 years age group. Adiposity was assessed in terms of BMI, Body Fat %, Fat Mass, Fat Mass Index and Waist Circumference. Arterial blood pressure was recorded and pulse pressure (PP) was calculated using the standard equation based on the difference between systolic blood pressure (SBP) and diastolic blood pressure (DBP). Pearson's correlation coefficient was determined to find the association between the markers of adiposity and SBP, DBP and PP.
A significant positive correlationship was found between adiposity and PP in boys. However, no significant correlationship was found between adiposity and PP in girls.
An increase in total as well as visceral adiposity is probably associated with a decrease in vascular distensibility in the Gujarati Indian adolescent boys but not in girls, thus indicating a protective role of female sex hormone estrogen which has been shown earlier to protect the vasculature from atherosclerosis, endothelial dysfunction which occurs with increase in adiposity.
开展本研究以确定肥胖对古吉拉特邦印度青少年血管扩张性的影响,因为表明超重和/或肥胖的印度青少年高血压发病机制的研究较少,且高血压发病机制存在种族差异。
对488名年龄在16 - 19岁的古吉拉特邦印度青少年进行了一项横断面研究。根据体重指数(BMI)、体脂百分比、脂肪量、脂肪量指数和腰围评估肥胖情况。记录动脉血压,并根据收缩压(SBP)和舒张压(DBP)之差,使用标准公式计算脉压(PP)。通过计算皮尔逊相关系数来确定肥胖指标与收缩压、舒张压和脉压之间的关联。
在男孩中,肥胖与脉压之间存在显著正相关。然而,在女孩中,肥胖与脉压之间未发现显著相关性。
总体及内脏肥胖的增加可能与古吉拉特邦印度青少年男孩而非女孩的血管扩张性降低有关,这表明女性性激素雌激素具有保护作用,此前已表明雌激素可保护血管免受动脉粥样硬化、随着肥胖增加而出现的内皮功能障碍的影响。
