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 Postmenopausal Estrogen/Progestin Interventions Study: primary outcomes in adherent women.
OBJECTIVE To assess the efficacy of unopposed estrogen , and three estrogen/progestin regimens on selected heart disease risk factors among adherent women and to contrast those results with efficacy among all women in the PEPI study . DESIGN A 3-year , multicenter , r and omized , double-blinded , placebo-controlled clinical trial . PARTICIPANTS A total of 847 healthy postmenopausal women aged 45 to 64 years of age with no known contraindication to hormone therapy , who attended their 36 month clinical visit . INTERVENTION Participants were r and omized in equal numbers to one of the following treatments : ( 1 ) placebo ; ( 2 ) conjugated equine estrogen ( CEE ) 0.625 mg daily ; ( 3 ) CEE 0.625 daily plus medroxyprogesterone acetate ( MPA ) 10 mg , days 1 - 12 ; ( 4 ) CEE 0.625 daily plus MPA 2.5 mg daily ; or ( 5 ) CEE 0.625 daily plus micronized progesterone ( MP ) 200 mg , days 1 - 12 . ANALYSIS Analyses are based on adherent women , where adherence is defined as taking at least 80 % of pills at each 6-month visit . RESULTS Adherence rates were high in all groups except women with a uterus assigned to unopposed CEE . The difference in HDL-C levels result ing from the CEE vs. CEE+MP was approximately three times larger than in the intent-to-treat analyses , reaching statistical significance ( P < 0.05 ) . In each active treatment , LDL-C decreased 10 - 15 % . Triglycerides increased 15 - 20 % in each opposed CEE arm and over 25 % in the CEE only arm ; this difference was not statistically significant . Fibrinogen increased by 7 % among placebo adherers , but decreased or remained fairly stable among the active arm adherers . Systolic blood pressure increased 3 - 5 % in all treatment arms . Women adherent to the CEE+MPA arms had twice the increase of 2 h glucose levels as women adherent to CEE only , or CEE+MP ( 8 - 9 % vs. 3 - 4 % ) . Two-hour insulin levels decreased 3 - 12 % for all arms . The patterns of change for fibrinogen , SBP , 2 h glucose and insulin were similar to those from the intent-to-treat analyses . CONCLUSIONS In analyses limited to adherent women , all active treatments , compared to placebo , continued to have similar and favorable effects on LDL-cholesterol and fibrinogen and no significant effects on blood pressure or insulin levels . Given the overall high adherence rates in PEPI , the results are similar to the intent-to-treat analyses , as expected . Only the trend of HDL-C to have a larger increase in the CEE only arm ( in the intent-to-treat analyses ) gained statistical significance in analyses restricted to adherers
