Authors' conclusion

In a large population-based study, PHPT was associated with death, diabetes, renal stones, and osteoporosis, independent of serum vitamin D concentration.

Study context

Population
People with primary hyperparathyroidism (PHPT) across Tayside, Scotland, 1997–2019 (66.8% female)matched cohort
Exposure
PHPT vs age- and gender-matched cohort
  • PHPTn = 11,616
Outcome
Death (mortality)
Follow-up
Mean 8.8 years
Methodological detailsdata linkage, age- and gender-matched comparison cohort, Cox proportional hazards models
  • Data linkage

As reported in the abstract

Observational data: associations, not effects.

Further findings

CVD

Increased risk of CVD, HR
1.34 (1.24-1.45) (95% CI)

Cerebrovascular disease

Increased risk of cerebrovascular disease, HR
1.29 (1.15-1.45) (95% CI)

Diabetes

Increased risk of diabetes, HR
1.39 (1.26-1.54) (95% CI)

Renal stones

Increased risk of renal stones, HR
3.02 (2.19-4.17) (95% CI)

Osteoporosis

Increased risk of osteoporosis, HR
1.31 (1.16-1.49) (95% CI)

Outcomes after adjustment for serum vitamin D concentrations

Participants with serum vitamin D concentrations
2748
Increased risks for death, diabetes, renal stones and osteoporosis persisted, but not for CVD or cerebrovascular disease
