ABSTRACT
Objective To survey the prevalence of stress urinary incontinence(SUI)and related knowledge among postpartum women in Shanghai Melong district.Methods A questionnaire survey on the knowledge of stress urinary incontinence was conducted among 317 postpartum women who were home visited by Meilong Community Health Service Center between March 2017 and June 2017.The self-designed questionnaire included the general situation(age, height, weight, occupation, menstrual history), pregnancy and childbirth, and knowledge of SUI; the International Consultation on Incontinence Questionnaire Short form(ICIQ-SF)was also used.Total 317 questionnaires were distributed and 313 valid ones were retrieved(98.73%).Results The prevalence of SUI in the participants was 26.84%(84/313).Multivariate logistic regression showed that BMI≥24 kg/m2(OR=6.24, 95% CI: 3.41 -11.41), complicated metabolic syndrome(OR=9.84, 95% CI: 2.77 -34.96)and birth weight of previous child ≥4 kg(OR=0.09,95%CI:0.04-0.19)is independent risk factors for the development of SUI.The average SUI knowledge score was(10.39 +8.65)points, only 26.20%(82/313)of the participants knew Kegel training(score 5.99 ±1.60).The SUI knowledge level of postpartum women was associated with educational level(F=12.41),occupation(F=9.06), income(F=4.05), reproductive history(F=10.98)and presence of urinary incontinence symptom(F=22.31)(all P<0.05). Conclusion The knowledge level of maternal stress urinary incontinence in Meilong district is relatively low,and the publicity of SUI and pelvic floor rehabilitation knowledge should be enhanced for the pregnant women.
ABSTRACT
Objective To develop a method for determination of mercury in blood by atomic fluorescence spectrometry. Methods Using a thiourea extraction method, the mercury in blood is determined by atomic fluorescence spectrometry. Results The linearity of calibration curve of mercury was in the concentration of 0.000-10.00 ?g/L. The detection limit was 0.06 ?g/L. The recovery rates were 95.5%-100.3%.The RSDs were 4.1%-4.5%. Conclusion The method has the advantages of simple operation, high sensitivity, good repeatability and is applicable to the determination of mercury in blood.
