Heart Rate Variability in Metabolically Healthy and Metabolically Unhealthy Obese Premenopausal Women

Acta Endo (Buc) 2016, 12 (1): 35-42
doi: 10.4183/aeb.2016.35

Content. Metabolically healthy obese (MHO) individuals are characterized by absence of metabolic syndrome. The role of autonomic nervous system in metabolic profile of obese subjects has not been sufficiently investigated. Objective. We analyzed heart rate variability (HRV) in MHO and metabolically unhealthy obese (MUO) premenopausal women. Design. In 42 women metabolic profile was defined as MHO and MUO. Subjects and Methods. For metabolic profile Wildman, IDF and HOMA-IR criteria were used. Autonomic nervous system activity was assessed by analysis of heart rate variability. Results. There was no significant difference in HRV between MHO and MUO premenopausal women. In Wildman division, after adjustment for systolic blood pressure, RRNN and LF/HF were statistically different between groups (p=0.0001; p=0.029). In IDF division, adjusting for waist circumference, LF was significantly different between groups (p=0.004). In HOMA division, adjusting for HOMA, groups were different in SDNN (p=0.009), RMSSD (p=0.002), pNN50 (p=0.003), HF(p=0.002) and TP (p=0.005). Conclusions. Autonomic nervous system does not share the leading role in premenopausal women metabolic profile. The differences in HRV between MHO and MUO women depend on the metabolic health criteria. Systolic blood pressure, HOMA and waist circumference have significant effect on HRV differences between MHO and MUO premenopausal women.
