Based on Norwegian registry and census data, the influence of reproductive factors on excess mortality from cervical cancer was examined. Parity level had no impact on the excess mortality. In parous women, a beneficial effect of an early first birth was found, most pronounced in 20- to 39-year-old women with squamous cell carcinoma.
基于挪威的登记和人口普查数据,研究了生殖因素对宫颈癌超额死亡率的影响。产次水平对超额死亡率没有影响。在经产妇中,发现首次生育早有有益影响,在20至39岁患鳞状细胞癌的女性中最为明显。
