We used ICD\u201010 codes to specify postpartum hypertension, infection, or hemorrhage during PHU (i.e., \u201ccause\u2010specific PHU\u201d) because these are leading mortality causes.

Obesity was associated with cause\u2010specific PHU of postpartum hypertension (adjusted odds ratio [aOR]: 2.2, 95% confidence limits [CL]: 1.8\u20132.7, normal weight referent) and wound infection (aOR: 1.5, 95% CL: 1.2\u20131.8), but not hemorrhage (aOR: 0.9, 95% CL: 0.7\u20131.3), mastitis, or genitourinary infection (aOR: 1.1, 95% CL: 0.9\u20131.3).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Among individuals without other comorbidities, elevated BMI was associated with PHU.
