Journal Title: Harsukh Educational Charitable Society International Journal of Community Health and Medical Research - Year 2018, Vol 4, Issue 3
Abstract
Background:-Obesity is a nutritional health problem, which is a potential risk factor for cardiovascular morbidity and mortality and it is gradually rising and affecting a major section of adult population. Altered parasympathetic activity may be considered as a risk factor for obesity and vice versa. Material and method:- The present study is an attempt to pinpoint the defect (if any) in the activity of parasympathetic limb of the autonomic nervous system (ANS) in obesity. Total 80 subjects belonging to the age group of 18-60 years were recruited for the study. The participants were divided into two groups as non obese and obese based body mass index (BMI). The functioning of parasympathetic autonomic nervous system was evaluated by 4 non invasive cardiovascular reflex tests- Resting heart rate,30:15 ratio, expiration/inspiration ratio (E/I ratio) and valsalva maneuver Results:-In the present study, the resting heart rate (beats/minute) was insignificantly (p>0.05) higher in obese subjects and lower values of Expiration/inspiration ratio ,30:15 Ratio and Valsalva Ratio were found in obese subjects when compared to normal weight subjects indicating reduced vagal or parasympathetic activity. Statistically result of Expiration/inspiration ratio and 30:15 Ratio showed significant results (p-value<0.05) and on the other side result of valsalva maneuver showed statistically insignificant result(p-value>0.05).Conclusion:-So from our study it may concluded that there is need of early interventional programs (weight reduction, life style changes and physical exercise) to prevent obesity related cardiovascular sequel in future.
