Figure 2. Total gestational weight change in pre-pregnancy body mass index specific quintiles and the adjusted association with all-cause mortality stratified by pre-pregnancy body mass index (n=46,042).
Abbreviations: BMI, body mass index; CI, confidence interval; IQR, interquartile range; HR, hazard ratio.
a Quintiles of gestational weight change were defined within each pre-pregnancy BMI category. Overall, the minimum weight change was −12·7 kg; however, the 5th percentile was −4·5 kg. The maximum weight change was 34·0 kg; however, the 95th percentile was 18·1 kg.
b Mortality rate estimated obtained from a single imputed dataset.
c Analyses adjusted for the following index pregnancy variables: age, smoking, race/ethnicity, parity, marital status, income, education, preexisting diabetes, preexisting cardiovascular conditions, preexisting cancer/tumors, preexisting neurological conditions, preexisting renal conditions, preexisting respiratory conditions, prior pregnancy loss, site, study year, pre-pregnancy body mass index, gestational week at delivery.
