The Cox proportional hazards regression model was applied to estimate the associations of formaldehyde with hypertension and angina pectoris symptoms. Mediating effect analysis was used to investigate the mediating effect of hypertension between formaldehyde exposure and angina pectoris symptoms. Long\u2010term exposure to formaldehyde was positively associated with the risk of angina pectoris symptoms (hazard ratio [HR], 1.66 [95% CI, 1.29\u20132.13], per interquartile range [IQR], 3.33, 10\n              <jats:sup>15<\/jats:sup>\n              molecules\/cm\n              <jats:sup>2<\/jats:sup>\n              ) and hypertension (HR, 1.17 [95% CI, 1.02\u20131.34], per IQR, 3.34, 10\n              <jats:sup>15<\/jats:sup>\n              molecules\/cm\n              <jats:sup>2<\/jats:sup>\n              ). The associations between formaldehyde and angina pectoris symptoms were greater in participants aged \u226565\u2009years (HR, 1.90 [95% CI, 1.29\u20132.80]) and in rural areas (HR, 2.71 [95% CI, 1.54\u20134.77]), whereas the associations of formaldehyde with hypertension were stronger in men (HR, 1.27 [95% CI, 1.02\u20131.58]), rural areas (HR, 1.22 [95% CI, 0.94\u20131.59]), and in ever smokers (HR, 1.33 [95% CI, 1.02\u20131.72]). The mediation effect analysis indicated that 18.44% (95% CI, 2.17\u201337.65) of the association between formaldehyde exposure and angina pectoris symptoms was mediated by hypertension.\n            <\/jats:p>\n          <\/jats:sec>\n          <jats:sec xml:lang=\"en\">\n            <jats:title>Conclusions<\/jats:title>\n            <jats:p xml:lang=\"en\">Long\u2010term exposure to ambient formaldehyde was positively associated with hypertension and angina pectoris symptoms.
