Since this is a vital developmental phase, studying the health patterns of young adults, particularly cardiovascular health, is critical. Autonomic function testing (AFT) is a crucial non-invasive procedure for determining the state of one's cardiovascular system. There are only a few studies on autonomic responsiveness in young people. To study the autonomic responses to various cardiovascular autonomic function tests among young adult subjects and to look into the gender-based variations.Males made up 114 (50.67 percent) of the total 225 individuals, while females made up the rest. The study's target age group was 18-29 years old. The CANWIN analyser of genesis medical systems was used to investigate autonomic function tests such as resting heart rate, heart rate reaction to slow deep breathing (SDB), Valsalva Ratio (VR), 30:15 ratios response to standing, and blood pressure response to sustained handgrip. CANWIN is a state-of-the-art Cardiac Autonomic Neuropathy (CAN) Analysis System with interpretation for PC Windows*. The data was analysed statistically using STATA software (version 13.1).: Dysautonomia was seen in 150 of the 225 participants (66.66 percent). The number of dysautonomia participants was not statistically different between males and females (P value=0.15).: Anxiety, stress, a poor diet, and a disrupted sleep cycle could all contribute to the high number of dysautonomia patients. There have been a number of reports linking dysautonomia to nutritional deficits. To investigate the causative factors, more longitudinal studies including nutritional status assessments are needed.

Background: The sex hormones, estrogen, and progesterone, as well as the gonadotropins, luteinizing hormone, and follicle-stimulating hormone produced from the anterior pituitary, govern the three stages of the menstrual cycle: menstrual, follicular, and luteal. Hormone fluctuations cause changes in autonomic function. There have been relatively few studies that show autonomic function modification throughout various periods of the menstrual cycle. Aim and Objectives: The current study was undertaken to investigate the difference in mean parasympathetic autonomic characteristics between the proliferative and secretory stages of the menstrual cycle. Materials and Methods: A total of 120 healthy young adult female volunteers were recruited among Kalinga Institute of Medical Sciences, Kalinga Institute of Nursing Sciences, and Kalinga Institute of Dental Sciences students. The study eliminated 20 students who were in the bleeding phase of their cycle. The electrocardiogram was captured, and parasympathetic parameters were determined using the fully automated CANWin instrument in the Department of Physiology. The data of the abovementioned parameters were compiled, tabulated, and entered into Microsoft Excel 2013 and statistically analyzed using STATA software 15.1. Results: The subjects’ mean ages, heights, and weights were 18.9 ± 0.70 years, 156.6 ± 5.25 cm, and 53.7 ± 8.63 kg, respectively. The mean resting heart rate in the secretory phase was substantially greater than in the proliferative phase, indicating sympathetic dominance. The 30:15 ratio between proliferative and secretory stages. The mean E: I ratio calculated from the slow deep breathing maneuver reveals a statistically significant difference between the proliferative and secretory phases. Conclusion: During the secretory phase, there is a considerable rise in parasympathetic activity among the individuals in the current study. Changes in parasympathetic activity throughout the follicular and secretory stages of the menstrual cycle may be caused by fluctuations in estrogen and progesterone levels.
