How can you use “menarche” in a sentence? Here are some example sentences to help you improve your vocabulary:
Prehn and West, using 1990 census data, calculated breast cancer incidence rates for aggregations of census block groups matched to Marin County on characteristics associated with higher breast cancer risk (percentage white population, urban status, average parity, median household income, percentage of persons with a college degree, percentage of persons with a working-class occupation, and percentage of households living below the poverty line), and found rates in the matched areas to be comparable with those in Marin County [ 4 ] . In another study using interview-based information, higher breast cancer incidence rates among white women in the SFBA were also fully explained by the distribution of parity, age at first birth, months of breast-feeding, age at menarche, and age at menopause [ 5 ] . Other previous analyses of nationwide variation in breast cancer incidence and mortality found most of it attributable to the distribution of known breast cancer risk factors [ 15 16 ] . It thus seems likely that a substantial part of the excess incidence observed in Marin County is explained by a higher concentration of women with a higher breast cancer risk profile.
Although the biological mechanisms underlying the inverse association between menarcheal age and adult obesity are uncertain, it has been suggested that early maturing girls may have a longer period of positive energy balance [ 1 ] , or that various endocrine factors influence both the rate of sexual maturation and the accumulation of body fat [ 6 ] . However, it is also possible that the apparent influence of menarcheal age on adult obesity reflects the underlying importance of childhood obesity, with relatively fat children at increased risk for both early menarche [ 7 9 13 14 15 ] and adult obesity [ 7 16 ] .
Despite the absence of a strong difference in age at menarche between cases and controls in this group, those women who developed breast cancer had relatively later menopause, indicating a greater number of years of active menstruation.
However, most (60% to 75%) of the apparent effect of menarcheal age is due to the faster maturation of girls who are relatively heavy for their age, and the importance of childhood obesity on the subsequent timing of menarche was evident even among 5- to 6-year-olds.
In multivariable logistic regression analysis, adjusted for age, age at menarche, age at first pregnancy and height, there was no significant association between the WHR and breast cancer risk (Table 3).
