Abstract
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.
