“…Consistent with the results of other studies (23,24), a high proportion of subjects (62.1%) were able to recall accurately their ages at menarche. Similar to Koo and Rohan (23), we observed that the longer the interval between menarche and recall, the less accurate was the respondent's recall of age at menarche.…”

KOPROWSKI, CAROL, RALPH J. COATES, AND LESLIE BERNSTEIN. Ability of young women to recall past body size and age at menarche. Obes Res. 2001;9: 478 -485. Objective: The ability of young women (n ϭ 132, average age 17 years) to recall body size and age at menarche was examined. The use of body silhouettes to assist women in recalling their body size at menarche and to represent their current body size was also evaluated. Research Methods and Procedures: Subjects, who previously participated in a cohort study, were asked to recall height and weight at the time of menarche, to select body silhouettes that best reflected their body shape at the time of menarche and their current body shape, and to recall age at menarche. Two sets of body silhouettes were developed, one representative of an adult body shape and another representative of an adolescent body shape. Results: Pearson correlation coefficients between the adult and adolescent body figures and actual body mass index (BMI; kg/m 2 ) at the time of menarche were not significantly different (r ϭ 0.82 for adult figures vs. r ϭ 0.72 for adolescent figures, p Ͼ 0.05). The correlation between actual BMI at the time of menarche and body silhouette (r ϭ 0.77, all subjects) was similar to the correlation between actual and recalled BMI at the time of menarche (r ϭ 0.83) as well as the correlation between current BMI and current body silhouette (r ϭ 0.75). Recalled and actual ages at menarche were highly correlated (r ϭ 0.83). Discussion: The recall of body shape was considered to be a less precise measure of body size than asking about height and weight, but use of body silhouettes may offer advantages in certain situations.

“…A limitation of our study was that age at menarche was reported by recall many years later. However, other studies have shown high correlations (r=0.67 to 0.79) between age at menarche by recall during middle-age and the original childhood data [17,18]. Bias is unlikely and the observed association may therefore be slightly weakened by regression dilution.…”

Association between age at menarche and risk of diabetes in adults: results from the EPIC-Norfolk cohort study

et al. 2008

Aims/hypothesis Earlier age at menarche is associated with increased BMI and obesity risk from early childhood through to adulthood. We hypothesised that earlier age at menarche would also predict subsequent diabetes risk. Methods This was a population-based prospective cohort study of 13,308 women, who were aged 40 to 75 years between 1993 and 1997 and participating in the Norfolk cohort of the European Prospective Investigation into Cancer and Nutrition (EPIC-Norfolk). We used data on age at menarche and ascertained diabetes incidence to 2005. Results There were 734 cases of diabetes (363 incident and 371 prevalent cases). Mean age at menarche was lower in women with diabetes than in non-diabetic women (12.8 vs 13.0 years, p=0.008). Compared with the earliest quintile (menarche at 8-11 years), women in the oldest quintile (menarche at 15-18 years) had lower BMI (25.5 vs 27.4 kg/m 2 , p<0.0001) and a reduced risk of diabetes (OR 0.66 [95% CI 0.51-0.86] adjusted for age, family history, physical activity, smoking, occupational social class, parity and use of hormonal preparations). The association between age at menarche and diabetes was linear (adjusted OR 0.91 [95% CI 0.87-0.96] per 1 year later menarche) and appeared to be completely mediated by adult BMI or waist circumference , further adjusted for BMI at age 40-75 years). Conclusions/interpretation Earlier age at menarche increases the risk of diabetes in women and this association appears to be mediated by increased adiposity. History of earlier menarche may help to identify women with increased subsequent risk of diabetes.

“…(1,(5)(6)(7)(23)(24)(25)(26) This relationship has been mainly studied in women, partly because menarcheal age is a rather reliable and easily assessed measure of pubertal timing. (27)(28)(29) No similar self-reported measure is available in men. Age at PHV, used in the present study, is an objective assessment of pubertal timing that can be used in both genders.…”

The aim of this study was to investigate the development of bone mineral density (BMD) and bone mineral content (BMC) in relation to peak height velocity (PHV), and to investigate whether late normal puberty was associated with remaining low BMD and BMC in early adulthood in men. In total, 501 men (mean AE SD, 18.9 AE 0.5 years of age at baseline) were included in this 5-year longitudinal study. Areal BMD (aBMD) and BMC, volumetric BMD (vBMD) and cortical bone size were measured using dual-energy X-ray absorptiometry (DXA) and pQCT. Detailed growth and weight charts were used to calculate age at PHV, an objective assessment of pubertal timing. Age at PHV was a strong positive predictor of the increase in aBMD and BMC of the total body (R 2 aBMD 11.7%; BMC 4.3%), radius (R 2 aBMD 23.5%; BMC 22.3%), and lumbar spine (R 2 aBMD 11.9%; BMC 10.5%) between 19 and 24 years (p < 0.001). Subjects were divided into three groups according to age at PHV (early, middle, and late). Men with late puberty gained markedly more in aBMD and BMC at the total body, radius, and lumbar spine, and lost less at the femoral neck (p < 0.001) than men with early puberty. At age 24 years, no significant differences in aBMD or BMC of the lumbar spine, femoral neck, or total body were observed, whereas a deficit of 4.2% in radius aBMD, but not in BMC, was seen for men with late versus early puberty (p < 0.001). pQCT measurements of the radius at follow-up demonstrated no significant differences in bone size, whereas cortical and trabecular vBMD were 0.7% (p < 0.001) and 4.8% (p < 0.05) lower in men with late versus early puberty. In conclusion, our results demonstrate that late puberty in males was associated with a substantial catch up in aBMD and BMC in young adulthood, leaving no deficits of the lumbar spine, femoral neck, or total body at age 24 years. ß
