In preparation for introducing the injectable contraceptive norethisterone enanthate (NET-EN) into the national family planning program, a field study was conducted in 6 family planning clinics in Bangladesh. 3 of the clinics were located in Dhaka, the capital city, 1 was located in a town approximately 15 kilometers from Dhaka, and the other 2 clinics were located several hundred kilometers from Dhaka. A total of 913 women were chosen to receive injections of NET-EN every 8 weeks for 6 months and every 12 weeks thereafter. The mean age of the subjects was 26.8 years, and the mean number of live births was 3.4. The overall cumulative discontinuation rates were 26.3/100 women at 6 months, 37.3/100 at 12 months, and 42.9/100 at 18 months. The most common reason for discontinuing was a disturbance in bleeding. Heavy and/or prolonged bleeding was the single most frequent reason (6.3/100 women at 12 months), but amenorrhea was not uncommon (5.1/100 women at 12 months), while irregular bleeding or spotting was given as a reason somewhat less frequently (3.9/100 women). 3 women became pregnant during the study, giving a cumulative pregnancy rate of 0.4/100 women at 18 months. A variety of complaints fell within the category of "other medical reasons," the most common being fatigue, headache, and dizziness. The overall discontinuation rates varied markedly by center, as did the reasons for discontinuation. The lowest discontinuation rate of 14.7/100 women at 12 months was seen in the Mohammedpur Fertility Services and Training Center. This rate was considerably lower than that in any other center. The highest discontinuation rate was found by the Bangladesh Association for Voluntary Sterilization -- 52.0/100 women at 12 months. The variation in rate of discontinuation because of bleeding disturbances was most dramatic, with relatively high rates at the Bangladesh Association for Voluntary Sterilization, markedly low rates in the Mohammedpur Fertility Services and Training Centre, and intermediate rates elsewhere. Neither the overall discontinuation rate, nor the individual reasons for discontinuation varied much by age group. The most notable finding regarding discontinuation of NET-EN was the marked difference between centers. This is particularly notable given the lack of any major differences with respect to age, parity, residence, and history of contraception of the subjects. These findings suggest that the specific approach used in each clinic had a considerable impact on continuation rates and acceptance of NET-EN.

Menopause and the accompanying reduction in estrogen production may cause a number of symptoms in women which include hot flushes, sweating, mood and sleep disturbances, fatigue and urogenital dysfunction. The effectiveness of estrogen-based hormone replacement therapy (HRT) in ameliorating these symptoms, and in preventing long term sequelae such as osteoporosis, is well established. Comparative trials indicate that oral conjugated estrogens 0.625mg, oral ethinyl estradiol 0.02mg and transdermal estradiol 0.05mg have equivalent efficacy in relief of mild to moderate menopausal symptoms and prevention of bone mineral loss. Concomitant progestogen therapy is usually prescribed for women with intact uteri to protect against endometrial hyperplasia and carcinoma. The addition of progestogen maintains and may even enhance the bone-conserving effects of estrogen, and continuous regimens appear to reduce the incidence of irregular menses. Adverse reactions are predominantly local skin irritation with transdermal preparations (14% of patients) and systemic effects common to most forms of HRT including breast tenderness, flushing, headache and irregular bleeding, occurring in less than or equal to 2% of patients. Data concerning the effect of HRT on quality of life are limited, but most analyses have assigned utility values of 0.99 for mild and 0.95 for severe menopausal symptoms. However, recent clinical data suggest that these utility values may underestimate the impact of menopausal symptoms on quality of life. The cost benefit and cost effectiveness of HRT in the treatment of menopausal symptoms have not been fully researched, although preliminary results suggest that conjugated estrogens and transdermal estradiol compare well with alternative therapies such as veralipride and Chinese medicines. A Swedish study using a prevalence-based approach estimated that estriol treatment in all women with urinary incontinence aged greater than or equal to 65 years resulted in monetary savings compared with treating 20% of women. Cost-utility data indicated that the change in quality-adjusted life years (QALYs) with HRT was always positive, but the degree of change was determined by the baseline assumptions. Estimated changes in QALYs with HRT ranged from 0.006 for 5 years of treatment with unopposed estrogen in women with intact uteri, to 0.5 for 10 years of the same treatment in women with severe menopausal symptoms following hysterectomy. Compliance with HRT is suboptimal as 5 to 50% of women withdraw from therapy, thereby increasing costs per year of life saved.(ABSTRACT TRUNCATED AT 400 WORDS)

The injectable contraceptive depot-medroxyprogesterone acetate (DMPA) dissolves slowly and is released over 3 months to suppress ovulation. It is more than 99% effective at preventing pregnancy. More than 30 million women in 90 countries have used DMPA and none have died from using it. A World Health Organization [WHO] study showed that DMPA did not significantly increase the risk of breast cancer or other cancers. One study points to a small reduction in bone density with DMPA use, but the reduction did not become larger with long-term use and may even be reversible. The US Food and Drug Administration (FDA) thoroughly reviewed these studies and the experiences of DMPA users. This review resulted in the FDA's approving DMPA as a contraceptive in October, 1992. Almost all DMPA users experience menstrual changes with irregular bleeding and spotting occurring during the 1st few months. After 12 months, at least 50% of DMPA users experience amenorrhea, which some women consider a benefit. Other possible but rare side effects are weight gain, headache, breast tenderness, loss of libido, depression, nervousness, and fatigue. It takes longer for past DMPA users to conceive after stopping DMPA use than users of other contraceptive methods, but by 18 months more than 90% of past DMPA users who wanted to become pregnant conceived. DMPA does not protect users from sexually transmitted diseases (STDs) or HIV/AIDS. They need to use latex condoms to prevent STD/HIV transmission. DMPA users must return to their health care provider every 3 months for another injection. DMPA is a viable contraceptive for women wanting a safe, reliable, long-term, reversible contraceptive. Any woman wanting to use DMPA should discuss it with her provider.
