Birthweight and Glucose Tolerance Status Are Associated With Organ Sizes in Older Adults

Diabetes Obes MetabPublished longitudinal follow-up study

Authors' conclusion

Lower birthweight was associated with smaller kidneys, and to some extent lungs, and with larger adrenal glands, whereas diabetes and prediabetes were associated with larger kidney, liver and adrenal glands, and with lower pancreas volumes. Further studies are needed to understand the clinical and/or physiological implications of these findings.

Study context

Population
Participants aged 53–83 years from the Danish Inter99 20-year follow-up study, with original midwife birthweight recordsparticipants who underwent computed tomography imaging
Participants
1,212 participants
Exposure
Associations between birthweight and organ sizes, and differences in organ sizes across normoglycaemic, prediabetes and diabetes groups
Outcome
Kidney volume per 1 kg lower birthweight
Methodological detailscomputed tomography imaging, linear regression
  • Computed tomography imaging
  • Linear regression

Main finding

As reported in the abstract

Lower kidney volume per 1 kg lower birthweight

2.0%

95% CI 0.1%, 3.9%

Observational data: associations, not effects.

Further findings

Lung volume per 1 kg lower birthweight

Lower lung volume per 1 kg lower birthweight
3.8% (95% CI: 1.2%, 6.5%)
Further adjustment for subcutaneous and visceral adipose tissue attenuated the lung association
  • Adjusted for sex, age, birth year, preterm birth and body surface area

Adrenal gland volume per 1 kg lower birthweight

Larger adrenal gland volume per 1 kg lower birthweight
3.9% (95% CI: 0.3%, 7.5%)
  • Adjusted for sex, age, birth year, preterm birth and body surface area

Organ volumes by glycaemic status

Compared with normoglycaemic participants, individuals with prediabetes and/or diabetes showed larger liver, kidney and adrenal gland volumes, whereas pancreas volume was smaller
  • Adjusted for birthweight and body size
