WIDER IMPLICATION S The findings of this review indicate that alcohol consumption , particularly low and moderate alcohol intake , might be associated with later onset of menopause although the magnitude of the association is low .
BACKGROUND Early onset of menopause is associated with long-term health risks , including cardiovascular disease and premature death .
Although alcohol intake has been suggested to affect the age at which natural menopause occurs , results from observational studies are not consistent .
OBJECTIVE AND RATIONALE In the view of the differing risks to the health of early menopause and the increasing trends in alcohol consumption in women , in this systematic review , we aim ed to quantify the association between all levels of alcohol consumption and menopause onset .
Factors associated with age of onset and type of menopause in a cohort of UK women.
OBJECTIVE We sought to describe the pattern of  age at menopause  and factors associated with type of menopause . STUDY DESIGN This was a prospect i ve cohort study of 5113 postmenopausal health survey respondents in the Royal College of General Practitioners ' Oral Contraception Study .  Logistic regression was used to evaluate associations between sociodemographics , lifestyle , and medical history and menopause type . RESULTS Median age at natural menopause ( n = 3650 ) was 49.0 years ( interquartile range , 45.0 - 51.0 ) , and at surgical menopause ( n = 1463 ) was 42.4 years ( 38.0 - 46.4 ) . Early natural menopause was associated with smoking , ever-use of oral contraception , sterilization , and history of endometriosis ( all increased odds ratios ) and ever-use of hormone replacement therapy ( decreased ) . Surgical menopause was associated with manual social class , sterilization , and having a history of endometriosis , menorrhagia , or painful menstruation ( all increased ) , and ever-use of hormone replacement therapy ( decreased ) . CONCLUSION Age at natural menopause was younger in this cohort than in other studies . More associations were found for surgical menopause than early natural menopause
