Relationship between Two-week Prevalence of Cardiovascular and Cerebrovascular Diseases and Living Environment Factor of Community Residents in Xigu District, Lanzhou

Objective  To investigate the effect of living environment on the health of residents.

Methods  Totally 1 032 permanent residents selected randomly in Xigu District of Lanzhou city. A questionnaire was conducted to explore the living environment of cardiovascular disease and two-week prevalence rate.

Results  The authors in this investigation issued a total of 1 032 questionnaires, excluding 3 unvalid questionnaires, the final valid questionnaires were 1 029. The questionnaire recovery rate was 100% and the effective rate was 99.7%. After statistical analysis, the different family living environment of hypertension two-week prevalence rate showed that in the summer season of the different ventilation under the condition two-week prevalence rate of hypertension was statistically significant (χ²=20.633, P < 0.001). The single factor logistic regression analysis results showed that a family history of cardiovascular disease and ventiated 3 times or less in a week at summer and autumn showed higher rates of hypertension. However, the results appeared no statistical significance (P>0.05).In addition, different family living environment of cerebrovascular disease two-week prevalence rate comparison results showed that there were no significant differences (P>0.05).

Conclusions  There maybe no correlation between the incidence of cardiovascular and cerebrovascular diseases and different family living environment in Lanzhou Xigu District. Nevertheless, in summer and autumn ventilation and family history of cardiovascular disease could affect the incidence of hypertension in residents.
