Women taking HT had a significantly decreased incidence of fracture with long-term use .
Research ers found no strong evidence that HT has a clinical ly meaningful impact on the incidence of colorectal cancer .
AUTHORS ' CONCLUSIONS : Women with intolerable menopausal symptoms may wish to weigh the benefits of symptom relief against the small absolute risk of harm arising from short-term use of low-dose HT , provided they do not have specific contraindications .
HT may be unsuitable for some women , including those at increased risk of cardiovascular disease , increased risk of thromboembolic disease ( such as those with obesity or a history of venous thrombosis ) or increased risk of some types of cancer ( such as breast cancer , in women with a uterus ) .
The risk of endometrial cancer among women with a uterus taking oestrogen-only HT is well documented .
HT is not indicated for primary or secondary prevention of cardiovascular disease or dementia , nor for prevention of deterioration of cognitive function in postmenopausal women .
Although HT is considered effective for the prevention of postmenopausal osteoporosis , it is generally recommended as an option only for women at significant risk for whom non-oestrogen therapies are unsuitable .
BACKGROUND : Hormone therapy ( HT ) is widely provided for control of menopausal symptoms and has been used for the management and prevention of cardiovascular disease , osteoporosis and  dementia in older women .
This is an up date d version of a Cochrane review first published in 2005 .
OBJECTIVES : To assess effects of long-term HT ( at least 1 year 's duration ) on mortality , cardiovascular outcomes , cancer , gallbladder disease , fracture and cognition in perimenopausal and postmenopausal women during and after cessation of treatment .
The estrogen replacement and atherosclerosis (ERA) study: study design and baseline characteristics of the cohort.
The Estrogen Replacement and Atherosclerosis ( ERA ) trial is a three-arm , r and omized , placebo-controlled , double-blind trial to evaluate the effects of estrogen replacement therapy ( 0.625 mg/day oral conjugated estrogen ) with or without continuous low-dose progestin ( 2.5 mg oral medroxyprogesterone acetate/day ) versus placebo on progression of atherosclerosis .  A total of 309 postmenopausal women at five sites underwent baseline coronary angiography and were r and omized . Participants will have repeat coronary angiography  after an average of 3.25 years of treatment . The primary outcome of interest will be change in minimum diameter of the major epicardial segments , as assessed by quantitative coronary angiography . The primary aim is to test the hypothesis that either form of hormone therapy will slow the progression or induce regression of coronary atherosclerosis compared to placebo . The secondary aims are to assess the effects of the two treatments versus placebo on endothelial function ( measured using flow-mediated vasodilator responses ) , on several presumed mediators of estrogen 's effect on atherosclerosis ( i.e. , plasma lipids and lipoproteins , blood pressure , glucose metabolism , hemostatic factors , and antioxidant activity ) , on other factors that influence the development of coronary heart disease ( i.e. , diet , smoking status , exercise , weight , and health-related quality of life issues ) , and on clinical cardiovascular events . The ERA trial is the first angiographic endpoint clinical trial to examine the effects of postmenopausal hormone replacement on  coronary atherosclerosis in women . It will provide an unparalleled opportunity to determine if either regimen of hormone therapy is effective in slowing the progress of angiographically defined coronary atherosclerosis . This study will complement other estrogen replacement trials , such as the PEPI , HERS , and Women 's Health Initiative studies , to provide a more comprehensive examination of the effects of estrogen replacement on cardiovascular risk factors , anatomic and functional manifestations of atherosclerosis , and risk for coronary heart disease in postmenopausal women .
