RESUMO
Differences in the age at natural menopause were examined using a retrospective population sample of 289 naturally menopausal women. The mean age at natural menopause was 46.70 +/- 5.44 years. Earlier menopause occurred in women living in semiurban areas, divorced/separated and less educated women, and women who were younger at: first marriage, widowhood, divorce/separation and first or last full-term pregnancy. Later menopause occurred in women who had: irregular menstrual periods before 25 years, dysmenorrhoea and mid-cycle spotting. Duration of oral contraceptives use, weight and body mass index were significantly positively correlated with age at natural menopause. Multiple regression analyses indicated that age at last full-term pregnancy, residence, pattern of menstrual cessation and duration of oral contraceptive use were the significant predictors of the end of menstrual activity

Thirty patients having placenta previa and 20 normal pregnant women were investigated for the uterine and umbilical artery flow velocity waveforms during the third trimester of pregnancy. All c and idates were subjected to initial ultrasound examination, weekly Doppler ultrasound for uterine and umbilical artery S/D ratios, and weekly ultrasound for interval growth and BPS. Neonatal outcome was assessed by 1 and 5-minute Apgar scores, neonatal weight and placental weight. The study revealed no significant effect of placental location on uterine and umbilical artery S/D in cases of placenta previa and normal controls. However, cases of unilateral placenta previa had significantly higher uterine S/D ratio with compromised placental perfusion and low birth weight. Finally, the report recommended the use of uterine and umbilical artery Doppler studies complemented by standard surveillance tests as BPS to attain a more reliable assessment of fetal well-being
