Strengths and limitations
First, compared with similar studies, the number of participants in this
study is more than 700. Second, we investigated depression, anxiety,
hypertension and quality of life, and analyzed the influence of their
interaction on quality of life. Finally, a complex adjustment model
based on the concept of social support is also used. Social support
helps to explain the relationship between depression and anxiety and
quality of life by regulating the model, which provides evidence for the
mechanism of social support regulating depression and anxiety disorder.
This study is a cross-sectional study, so we can not get the causal
relationship between variables. The effect of confounding factors was
not taken into account, and the conclusion may be biased. In the future,
we will continue to do longitudinal research on the samples involved,
and consider more factors.
