Key result
Higher depression scores in seventh-grade students were associated with increased heart rate and lower standard deviation of heart rate, though these findings were not statistically significant.
Why the study?
Is there an association between depression/anxiety scores and heart rate variability in junior high school students?

Is there an association between depression/anxiety scores and heart rate variability in junior high school students?
The study suggests a potential, though not statistically significant, association between higher depression scores and altered heart rate variability in adolescents, particularly females.
BACKGROUND: The impact of depression and anxiety on heart rate variability (HRV) is not clear in adolescents. We hypothesised that HRV investigation in adolescents may early prevent the mental diseases occurrence. METHODS: Three hundred and thirty-three seventh grade students participated in this study programme. HRV instrumental analysis and spectral with scale of depression were measured respectively. RESULTS: It showed that among the participants, the depression score of female was higher than male. The population with lower depression score present with lower high frequency and higher low frequency/high frequency ratio but not statistically significant. Oppositely, participants with higher depression score were increased with heart rate and present with lower standard deviation of heart rate. However, it is also not statistically significant. CONCLUSION: This study supported the positive relation between HRV and depression, especially in the female gender. Therefore, HRV in depression may be beneficial in the detection and prevention of mental disorder development, even suicide behaviour in teenagers.

Kong-Sang Wan (2012) conducted a cross-sectional in Depression and anxiety (n=333). Depression vs. Lower depression score was evaluated on Heart rate variability parameters (high frequency, LF/HF ratio, heart rate, standard deviation of heart rate). Higher depression scores in seventh-grade students were associated with increased heart rate and lower standard deviation of heart rate, though these findings were not statistically significant.
