Abstract

Objective: To investigate the relation between preterm birth (gestational age <37 weeks) and risk of CKD from childhood into mid-adulthood. Design: National cohort study. Setting: Sweden. Participants: 4 186 615 singleton live births in Sweden during 1973-2014. Exposures: Gestational age at birth, identified from nationwide birth records in the Swedish birth registry. Main outcome measures: CKD, identified from nationwide inpatient and outpatient diagnoses through 2015 (maximum age 43 years). Cox regression was used to examine gestational age at birth and risk of CKD while adjusting for potential confounders, and co-sibling analyses assessed the influence of unmeasured shared familial (genetic or environmental) factors. Results: 4305 (0.1%) participants had a diagnosis of CKD during 87.0 million person years of follow-up. Preterm birth and extremely preterm birth (<28 weeks) were associated with nearly twofold and threefold risks of CKD, respectively, from birth into mid-adulthood (adjusted hazard ratio 1.94, 95% confidence interval 1.74 to 2.16; P<0.001; 3.01, 1.67 to 5.45; P<0.001). An increased risk was observed even among those born at early term (37-38 weeks) (1.30, 1.20 to 1.40; P<0.001). The association between preterm birth and CKD was strongest at ages 0-9 years (5.09, 4.11 to 6.31; P<0.001), then weakened but remained increased at ages 10-19 years (1.97, 1.57 to 2.49; P<0.001) and 20-43 years (1.34, 1.15 to 1.57; P<0.001). These associations affected both males and females and did not seem to be related to shared genetic or environmental factors in families. Conclusions: Preterm and early term birth are strong risk factors for the development of CKD from childhood into mid-adulthood. People born prematurely need long term follow-up for monitoring and preventive actions to preserve renal function across the life course.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
