Objective To investigate the association of menstrual, marital, childbearing, sexual life and sex hormone level to natural longevities(>=90 years old) of Uygur nationality people in Hetian area of Xinjiang Uygur Autonomous Region. Methods A questionnaire for natural longevity and interrelated factors was used through the systemic survey in Luopu County, Moyu County and Hetian County of Xinjiang Hetian area. The level of estradiol (E2 ) and testosterone (T) was measured by radioimmunoassay. All data were compared with those of 65-70-year-old Han nationality and Kazak nationality people. Results The sex ratio of male to female longevity was 1.8:1; remarriage rate was 73% and average marriage frequency was 3. 65 times for male longevity. The main characters in this area included marriage between elder husband and younger wife, a stable family status and keeping normal sexual life. T level was 19. 6 nmol/L, closed to that of the elder Han nationality and Kazak nationality people. For female longevity people, femininities, early marriage and more than one marriage throughout women's life (average 2. 62 times), lower social status in family, poor medical conditions during childbearing were main characters. E2 level (21.9 pmol/L) was higher in Uygur longevity than that in general elder Uygur and Han populations, and in the same level as that of Kazak elder women. Conclusions The Uygur natural longevity of male in Hetian area was more than that of female (male/female 1. 8:1), all higher than the same aged people of Han and Kazak nationalities. It may relate to the normal family status, normal sexual life and keeping higher level of estradiol and testosterone may contribute to the natural longevity.
