A study to assess reaction time and its association with adiposity indices in healthy individuals in Uttarakhand

Introduction: Reaction time is the central indicator of the central nervous system's sensorimotor coordination and processing skills, as well as coordinated peripheral movement response. There is a substantial positive link between body mass index (BMI) and reaction time. However, no studies on the impact of old and novel adiposity indices on cognitive capacity measurement have been done. As a result, this study was carried out to see if there was a link between visceral adiposity index (VAI) and lipid accumulation product (LAP) and reaction time in healthy Uttarakhand residents. Materials and Methods: The observational study was conducted in 2018 from January to June at AIIMS, Rishikesh to screen 89 individuals aged 20–40 years, who were in good health and lived in adjacent areas to examine reaction time simple reaction time (SRT) and choice reaction time [CRT]) and its relationship with adiposity indices. The Deary-Liewald reaction time task (software) was used to examine the participants' reaction time, which was followed by anthropometric measurements and other biochemical tests. Results: Among 89 individuals, 61% were male and 39% were female. In terms of age, BMI, waist circumference (WC), waist-to-hip ratio, and response time, there was no significant difference between males and females. However, males had a faster reaction time than females. VAI is substantially higher in females than in males. Females have more LAP than males, although the difference is not statistically significant. Conclusion: LAP had a substantially better association than BMI and WC in the case of females with respect to the association with CRT because LAP includes both anthropometric WC and lipid parameters (triglycerides). In healthy people, LAP could be recommended as a superior indicator for assessing response time as a measure of cognitive ability.
