[Intake of soy isoflavones and its correlation with prevalence of chronic diseases among rural women in Weichang County and Lanzhou City in China].
To evaluate the average intake of soy isoflavones and the correlation between this intake and prevalence of chronic diseases among Chinese rural women, soy food consumption and medical history of 1188 recruited rural adult women from Weichang County (Hebei Province) and Lanzhou City (Gansu Province) were collected using food frequency questionnaire. The results showed that the intake of soy isoflavones by Weichang and Lanzhou women was (15.3 +/- 18.9) mg/d (M = 8.8) and (19.5 +/- 32.9) mg/d (M = 10.1), respectively. There had statistically significant difference (P < 0.05). The distribution of soy isoflavones intake was skewed to the right. The reported disease prevalence in Weichang was 25.6% and higher than that in Lanzhou (18.8%). The average intake of soy isoflavones by healthy women was (17.8 +/- 22.8) mg/d (M = 9.5), which was higher than that by women who reported to have one of chronic diseases [(15.7 +/- 22.5) mg/d (M = 8.3)] and significantly higher than that by women who reported to have cardiovascular diseases or chronic digestive system diseases (P < 0.05). These findings indicated an inverse correlation between soy isoflavones intakes and the prevalence of chronic diseases, suggesting that soy isoflavones may play a potential role in the prevention for chronic diseases.
