Background: Sedentary lifestyle is public health concern that threatening human health. It is an independent predictor of cardiovascular disease (CVD) morbidity and mortality. Sedentary lifestyle affect the autonomic nervous system thus cardiovascular health.

Methods: This cross-sectional analytical study was conducted from January 2019 to December 2019 in the Department of Physiology, Rangpur Medical College, Rangpur. After obtaining permission, a total 120 subjects who were met the inclusion criteria was enrolled in the study after briefing them objectives of the study. Among them 30 were healthy adult male sedentary workers (Group-A), 30 healthy adult male light workers (Group-B), 30 were healthy adult male moderate workers (Group-C) and 30 were healthy adult male heavy workers (Group-D). The evaluation of cardiovascular autonomic functions of selected individuals was done by performing six simple noninvasive cardiovascular autonomic reflex tests as diagnostic tools. The individuals were selected from different areas of Rangpur district. For statistical analysis one-way ANOVA (post-Hoc) test was performed by computer-based software SPSS-23.0 version for windows. Significance for the statistical test was predetermined at a probability (p) value of < 0.05.

Results: Resting heart rate (p < 0.001), resting systolic blood pressure and resting diastolic pressure were significantly higher in group A (p < 0.01). Heart rate response to valsalva maneuver was significantly lower in group A (p < 0.01). Heart rate response to deep breathing was significantly lower in group A (p < 0.01). Heart rate response to standing was significantly lower in group A (p < 0.05). Blood pressure response to sustained handgrip was significantly lower in group A (p < 0.01). Blood pressure response to standing was not significantly lower group A (p > 0.05). Systolic blood pressure in response to cold pressor test was significantly lower in group A (p < 0.01). Diastolic blood pressure in response to cold pressor test was significantly lower in group A (p < 0.001). Among the sedentary workers 19 (63.34%) showed impaired cardiovascular autonomic nerve functions.

Conclusion: Sedentary workers exhibit modifications in the autonomic nervous system characterized by a reduction in both sympathetic and parasympathetic activity.
