OBJECTIVE: We aimed to assess the reliability of self-reported reproductive variables in postmenopausal women.
STUDY DESIGN AND SETTING: We evaluated 535 women in two interviews, as part of the recruitment and first follow-up of a cohort of Portuguese adults. Median time between evaluations was 5 years. Women were inquired about sociodemographic characteristics, cognitive status, and reproductive history: gravidity, parity, lifetime use of oral contraceptives, menopausal status, age at menopause, hysterectomy, oophorectomy, and lifetime use of hormone replacement therapy (HRT).
RESULTS: Age at menopause was consistent within 1 year for 66% of women and agreement was higher in women reporting surgical menopause. Reliability regarding age at menopause decreased with time since menopause. Gravidity was consistent for 81% of women, whereas parity was consistent for 94%. The proportion of different answers regarding number of pregnancies and number of live births was higher in women with high gravidity and parity, respectively. Agreement was 96% for hysterectomy and 92% for oophorectomy. The proportion of consistent reports was 90% for oral contraceptives and 93% for HRT. Women with higher education reported parity and HRT more reliably.
CONCLUSION: Agreement was over 90% for self-reported parity, hysterectomy, oophorectomy, and HRT, which supports their use in analytical studies.
