Association between noise pollution perception and prevalence of cardiovascular disease in a Chinese adult population: a cross-sectional study based on the CGSS 2021 cardiovascular disease dataset.

ObjectiveTo explore the association between Chinese adults' subjective perception of noise pollution and the prevalence of cardiovascular diseases, so as to make up for the deficiencies in data and perspectives of previous studies and provide a basis for formulating relevant prevention and control strategies.MethodsA total of 2,717 relevant records from the 2021 China General Social Survey (CGSS 2021) cardiovascular disease dataset were used. The core independent variable was the degree of noise pollution perceived by residents themselves (low pollution, high pollution), and the dependent variable was whether they suffered from cardiovascular diseases (including hypertension, dyslipidemia, heart disease, and stroke). Data processing and statistical analysis were conducted through chi-square test and binary Logistic regression analysis using software such as SPSS 25.0 and Stata 12.0.ResultsThere was no statistically significant difference in the prevalence of overall cardiovascular diseases (χ2 = 0.083, P = 0.773), hypertension (χ2 = 0.790, P = 0.374), dyslipidemia (χ2 = 2.063, P = 0.151), heart disease (χ2 = 2.596, P = 0.107) and stroke (χ2 = 3.748, P = 0.053) between the group with high noise pollution perception and the group with low noise pollution perception. However, after controlling for confounding factors, the group with higher noise pollution perception had a higher prevalence of heart disease compared with the group with lower noise pollution perception (OR = 1.751, 95% CI = 1.203~2.550, P < 0.01).ConclusionThere is a significant positive association between Chinese adults' subjective perception of noise pollution and the prevalence of heart disease. This suggests that when formulating strategies for noise pollution prevention and control and cardiovascular disease prevention, both objective data and residents' subjective perceptions need to be considered.
