目的:了解上海市城区产后妇女意外妊娠的发生及其影响因素。方法:通过结构式问卷,对1767名产后1-2年妇女的产后意外妊娠情况进行调查。结果:产后第1年和第2年意外妊娠发生密度分别为4.64/100人年和6.57/100人年。产后性生活恢复、避孕开始、母乳喂养和产后闭经的中位时间分别为产后4个月、5个月、6个月和4个月。产后妇女最常用的3种避孕措施为避孕套、安全期和体外排精。产后1年内意外妊娠单因素分析显示:不同年龄组、文化程度、户籍、产后性生活开始早晚、母乳喂养及闭经时间长短间意外妊娠的发生密度差异有统计学意义(P<0.05)。多元Cox逐步回归分析显示,产妇年龄越大、母乳喂养时间越长、性生活开始时间越晚,产后1年内意外妊娠发生的风险越小;而外来人口意外妊娠发生的风险高于户籍人口。结论:产后妇女避孕开始滞后于性生活恢复,大多使用避孕效果相对不太稳定的避孕方法。外来人口、年轻产妇、产后开始性生活较早、母乳喂养时间较短的人群是产后1年内意外妊娠的高危人群。产后应尽早落实可靠的避孕措施及加强避孕套正确使用的宣教。 相似文献

产后暴露于无避孕措施的性行为及其影响因素分析 总被引:9,自引:0,他引:9
本文利用上海市两个区和两个郊县3898名妇女产后15个月的随访资料.对产后意外妊娠的危险因素—暴露于无避孕措施的性行为及其影响因素进行了分析。结果显示,产后意外妊娠的妇女中,44.1%因未用避孕措施而妊娠,其中95.5%的妇女妊娠前从未使用过任何避孕措施。产后首次性生活时妇女避孕措施使用的比例仅34.53%,市区高于郊县。产后一年内恢复性生活的妇女仅33.0%每次性生活都用避孕措施。性生活未立即使用避孕措施的主要原因为:认为哺乳期不会怀孕,认为未转经不会怀孕及认为性生活次数少不会怀孕。影响妇女产后性生活时是否使用避孕措施的因素有:居住地、妇女受教育程度、职业、首次性生活时是否已转经、夫妇产后是否接受过有关产后性生活和产后避孕的宣教及产后性生活开始时间等。研究结果提示:应加强对产后避孕的宣教,纠正错误的传统观念,提高妇女产后的避孕率。 相似文献

OBJECTIVE: To determine the potential efficacy of two simple fertility awareness-based methods of family planning-the Standard Days Method and the TwoDay Method-among breastfeeding women. DESIGN: Analysis of pre-existing data set, collected in 1986-1990. SETTING: Pre-existing data from Australia, Britain, and Canada. PATIENT(S): Seventy-three breastfeeding women in Australia, Britain, and Canada, who were followed starting 42 days postpartum, until they had at least two potentially fertile cycles (defined as cycles with adequate levels of urinary estrogens (E) and pregnanediol glucuronide and a long enough luteal phase to support a pregnancy). We examine this existing data set. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Probability of pregnancy from intercourse on different days of the cycle relative to ovulation for breastfeeding women following the instructions of the Standard Days Method or the TwoDay Method. RESULT(S): These two methods may be appropriate for different groups of breastfeeding women at different times. The Standard Days Method may be appropriate after cycle regularity is established, whereas the TwoDay Method may be a more effective option earlier in the postpartum period. CONCLUSION: A need remains for a more appropriate simple fertility awareness-based method during this early period. 相似文献

OBJECTIVE: To test the efficacy of the TwoDay Method, a new fertility awareness-based method of family planning that provides women with simple instructions to identify the days each cycle when they are most likely to become pregnant. Users avoid unprotected intercourse on days when cervical secretions are present on that day or on the day before, to prevent pregnancy. DESIGN: Prospective, nonrandomized, multicenter study. SETTING: Five culturally diverse sites in Guatemala, Peru, and the Philippines. PATIENT(S): Four hundred fifty women, aged 18-39 years, wishing to use a fertility awareness-based method to prevent or delay pregnancy. INTERVENTION(S): Study participants were followed for up to 13 cycles of method use. MAIN OUTCOME MEASURE(S): Life table pregnancy rate. RESULT(S): The first-year pregnancy rate was 3.5 (pregnancies per 100 women/years) with correct use of the method (pregnancies and cycles with no intercourse on identified fertile days), 6.3 with use of a backup method on the fertile days, and 13.7 including all cycles and all pregnancies in the analysis. CONCLUSION(S): The TwoDay Method offers a valuable addition to the services that reproductive health and other programs can offer. Its efficacy compares well with that of other coitus-dependent family-planning methods; it is easy to teach, learn, and use; and it can address the need of women for simple, accurate instructions for identifying their fertile days. 相似文献

Helping clients select and use appropriate family planning methods is a basic component of midwifery care. Many women prefer nonhormonal, nondevice methods, and may be interested in methods that involve understanding their natural fertility. Two new fertility awareness-based methods, the Standard Days Method and the TwoDay Method, meet the need for effective, easy-to-provide, easy-to-use approaches. The Standard Days Method is appropriate for women with most menstrual cycles between 26 and 32 days long. Women using this method are taught to avoid unprotected intercourse on potentially fertile days 8 through 19 of their cycles to prevent pregnancy. They use CycleBeads, a color-coded string of beads representing the menstrual cycle, to monitor their cycle days and cycle lengths. The Standard Days Method is more than 95% effective with correct use. The TwoDay Method is based on the presence or absence of cervical secretions to identify fertile days. To use this method, women are taught to note everyday whether they have secretions. If they had secretions on the current day or the previous day, they consider themselves fertile. The TwoDay Method is 96% effective with correct use. Both methods fit well into midwifery practice. 相似文献

ObjectiveThis study investigated the efficacy of GnRH agonists concomitantly with transient aromatase inhibitor and tranexamic acid to treat women with uterine arteriovenous malformations (AVMs) associated with abnormal uterine bleeding (AUB) to preserve fertility and determine reproductive outcome.MethodsThis was a prospective cohort study in a tertiary centre. Doppler ultrasound demonstrated AVM in 19 women with AUB 1–28 weeks following spontaneous or therapeutic abortion and in one woman 4 years after normal pregnancy while taking an oral contraceptive. On the basis of experience from the first three cases, 17 women were treated with tranexamic acid (1 g three times daily orally for 5 days), a GnRH agonist (3.75–11.25 mg, for 1–3 months), plus an aromatase inhibitor (letrozole 2.5 mg once daily for 5days) with the initial injection of GnRH agonist. Two women required blood transfusion, and one required uterine tamponade with Foley catheter balloon in the first 48 hours to control heavy bleeding (Canadian Task Force Classification II-2).ResultsAll 20 AVMs resolved within 1–3 months of treatment. Of 16 women who attempted pregnancy, all (100%), including two who had uterine artery embolization (one after hysteroscopic septoplasty), conceived spontaneously with 18 live births. Two women are using contraception (one taking an oral contraceptive, one using a levonorgestrel intrauterine system), and one 40-year-old is not using contraception. One woman had hysteroscopic endometrial ablation followed by vaginal hysterectomy for AUB at 1 and 2 years later.ConclusionA GnRH agonist in combination with transient aromatase inhibitor and tranexamic acid is an effective management strategy to treat and maintain reproduction in women with AVMs associated with AUB. 相似文献

Objectives: To evaluate the effect on menstrual pain in women with primary and secondary dysmenorrhea of a novel 'frameless' intrauterine drug delivery system (IUS), FibroPlant-levonorgestrel (LNG) (Contrel Research, Belgium), releasing 14 μg of LNG per day. An ancillary objective was to evaluate the effect of the new IUS on menstrual blood loss. Study design: An open label, non-comparative ongoing pilot study. Eighteen insertions were performed in women between 16 and 52 years of age by the first author. Four insertions were performed in nulligravid women. Eight women were categorized as having primary dysmenorrhea and 10 as having secondary dysmenorrhea. Twelve women complained of heavy bleeding. Three women had significant fibroids and three were suspected to have adenomyosis. Results: The trial covers a period from a minimum of 3 months up to 33 months. By the end of August 2001, 12 recruited women had at least 12 months' follow-up and six had between 3 months and 1 year. All women reported much reduced pain, or no pain at all, and strongly reduced bleeding which started as soon as 1 month after insertion of the FibroPlant-LNG IUS. There was one exception; this woman had significant fibroids. She reported much reduced bleeding but this was not as pronounced as in the other women in the study. All women are continuing to use the method. Conclusion: The results of this preliminary study suggest that the FibroPlant-LNG IUS, releasing 14 μg of LNG per day, is a safe and effective method for the treatment of primary and secondary dysmenorrhea. The absence of a frame is particularly advantageous in these women. Of significant added importance is the high effectiveness in reducing menstrual bleeding, a symptom often present in women with menstrual pain complaints, and the fact that the system provides effective contraception. The low daily release rate of LNG from the FibroPlant-LNG IUS results in a virtual absence of hormonal side-effects. 相似文献

Forty-seven woman volunteers used a new highly potent stimulatory analog of the hypothalamic gonadotropin-releasing hormone (GnRH) for contraception. The superagonist nafarelin acetate, D-Nal(2)6-GnRH, was administered intranasally in one daily dose of 125 micrograms to 25 women and 250 micrograms to 22 women. Ovulation was consistently inhibited during 261 of 262 treatment months. No pregnancy occurred during 222 months in which no additional contraceptives were used. The mean plasma estradiol level after 6 months of treatment was 162 pmol/l. The predominant bleeding pattern was oligomenorrhea. Three women on the lower dose and six women on the higher dose discontinued the trial prematurely, mainly because of hot flushes. No serious side effects were reported. Ovulatory menstruations returned after a median time of 43 days after discontinuation of therapy. Daily intranasal nafarelin treatment for inhibition of ovulation proved to be an effective and rapidly reversible method of contraception. 相似文献
