BACKGROUND: The role of parental cardiorespiratory conditions on fracture risk is unclear. We examined the associations between parental cardiorespiratory conditions and offspring fracture risk.

METHODS: In this population-based retrospective cohort study, we identified 279,085 offspring aged≥40 years between April 1, 1997 and December 31, 2015 with successful linkage to 273,852 mothers and 254,622 fathers. Parental cardiorespiratory conditions, including cerebral vascular disease, congestive heart failure, hypertension, ischemic heart disease, myocardial infarction, chronic obstructive pulmonary disease (COPD) and peripheral vascular disease, were ascertained using physician and hospital records dating back to 1979. The outcome was offspring incident major osteoporotic fracture (MOF).

RESULTS: During an average of 11.8 years of offspring follow-up, we identified 8762 (3.1%) incident MOF. Either parent congestive heart failure (adjusted hazard ratio [HR]: 1.13; 95% confidence interval [CI] 1.07-1.19) and COPD (adjusted HR: 1.12; 95% CI 1.07-1.17) were independently associated with increased offspring MOF risk; all their false discovery rates were < 0.001. Similar risk estimates were observed when analyses were performed for fathers only, mothers only or both parents, in multivariable models with and without adjustment for offspring cardiorespiratory conditions, and stratified by offspring sex and offspring incident fracture site. Parental cerebrovascular disease, hypertension, ischemic heart disease and myocardial infarction were not associated with offspring MOF.

CONCLUSIONS: Parental congestive heart failure and parental COPD are independent risk factors for offspring MOF.
