Effect of gender on the association of adiposity with cardiovascular reactivity in Gujarati Indian adolescents.
Studies have reported that both gender and adiposity influence cardiovascular reactivity amongst adolescents. However, not much is known about the effect of gender on the association of adiposity with cardiovascular reactivity. The current study was conducted to learn how gender affects the association of adiposity with cardiovascular reactivity in the Gujarati Indian adolescents so as to develop preventive strategies for the local population. A cross-sectional study was conducted on 428 (Girls-173, Boys-255) Gujarati Indian adolescents of age group 16-19 years. Adiposity was assessed in terms of Body Mass Index (BMI), Body Fat Percentage (BF %), Fat Mass (FM), Fat Mass Index (FMI) and Waist Circumference (WC). Percentage Rise in Pulse Rate (%RPR) and Percentage Rise in Diastolic Blood Pressure (%RDBP) during Isometric Handgrip Test were used to assess the cardiovascular reactivity to acute sympathetic stress. Pearson's correlation coefficient was determined to find the association of adiposity with cardiovascular reactivity. Boys were found to have a significantly larger WC, higher physical fitness and greater %RDBP in comparison to girls while girls had a significantly higher BF% and FMI in comparison to boys. In both boys and girls, BMI, BF%, FMI and WC showed significant positive association with %RDBP with stronger correlationship found in girls. Girls also showed a significant negative correlationship between physical fitness and vascular reactivity. It could thus be concluded that gender affected the association of adiposity with vascular reactivity in Gujarati Indian adolescent such that girls tend to have a larger correlationship between adiposity and vascular reactivity than boys which is most likely due to lower physical fitness.
