Analysis of postmenopausal women in China links reproductive history — including age at menarche, parity, and age at menopause — to the population burden of ischaemic heart disease, with the magnitude of that burden differing across socioeconomic strata. Women in lower socioeconomic groups carry a disproportionate share of reproductive factor-associated cardiovascular risk. The findings position reproductive history as an early, documentable marker of long-term cardiovascular trajectory rather than an isolated obstetric detail.
Key Points
- Reproductive history predicts ischaemic heart disease burden in postmenopausal women
- Socioeconomic position modifies the size of that cardiovascular burden
- Menarche timing, parity, and menopause age carry decades-long vascular signal
Longevity Analysis
Reproductive timing is a readout of cumulative hormonal exposure, and that exposure shapes vascular structure, lipid handling, and endothelial resilience long before symptoms appear. A woman's menarche age, number of pregnancies, and menopause timing are already recorded in most medical histories — they constitute usable risk information that typically goes uninterpreted. The socioeconomic gradient indicates that the same reproductive profile does not carry equal consequence across populations; nutritional quality, chronic stress load, environmental exposure, and access to early intervention determine how that underlying signal expresses itself. Acting on this information means moving cardiovascular assessment decades earlier in women identified as higher risk, and addressing the modifiable burdens that amplify it.
