Abstract:
Objective: To determine the effect of breakfast taking
habits on Heart Rate Variability (HRV) amongst adults.
Methodology: This cross-sectional study was
conducted in department of Physiology, IIMC from
September 2022 to August 2023. It included 216
healthy, unhealthy breakfast consumers and breakfast
skippers. We used Breakfast Quality Evaluation
questionnaire. The ECG of the participants was
recorded using power lab data acquisition system. Heart
rate variability (HRV) was analyzed for frequency
domain parameters including Low Frequency (LFnu),
High Frequency (HFnu) and Low Frequency to High
Frequency (LF/HF) ratio by software lab chart 8 pro on
two consecutive days and average value was
considered. One way ANOVA in SPSS version 25 was
used to analyze data.
Results: LFnu was significantly low in healthy than
unhealthy breakfast consumers (p=0.028) and skippers
(p<0.001). Significantly low LFnu found in unhealthy
breakfast consumers than skippers (p=0.033). A
significantly high HFnu found in healthy breakfast
consumers than skippers (0.022). LF/HF ratio was
significantly low in healthy than unhealthy breakfast
consumers (p=0.002) and skippers (p<0.001). Results
were considered significant at 95% CI.
Conclusion: The breakfast taking habits of healthy,
unhealthy and breakfast skipping had impact on HRV.
Healthy breakfast was associated with increased HRV
as compared to unhealthy and breakfast skipping.
