摘要: OBJECTIVES: This study examined the prevalence and biosocial correlates of hysterectomy. METHODS: Data were from a 1995 national survey women aged 20 to 59 years. We applied piecewise nonparametric exponential hazards models subsample 25 estimate effects on hysterectomy likelihood. RESULTS: Risks for 1991 through lower than those before 1981. University-educated professional less likely undergo Higher parity intrauterine device side increased risk. CONCLUSIONS: confirms international results, especially education occupation, but also points ethnicity's mediating role. Education occupation covary independently with Analysis time variance periodicity showed declines in likelihood
