Association of ambient PM₁ exposure with maternal blood pressure and hypertensive disorders of pregnancy in China.

ABSTRACT: Evidence concerning PM₁ exposure, maternal blood pressure (BP), and hypertensive disorders of pregnancy (HDP) is sparse. We evaluated the associations using 105,063 participants from a nationwide cohort. PM₁ concentrations were evaluated using generalized additive model. BP was measured according to the American Heart Association recommendations. Generalized linear mixed models were used to assess the PM₁-BP/HDP associations. Each 10 μg/m³ higher first-trimester PM₁ was significantly associated with 1.696 mmHg and 1.056 mmHg higher first-trimester SBP and DBP, and with 11.4% higher odds for HDP, respectively. The above associations were stronger among older participants (> 35 years) or those educated longer than 17 years or those with
