“…In this study, there was no significant relationship between socioeconomic status and menarche age, which is consistent with the Sylvia Kirchengast's study in Austria in 2007 (27). However, this result was not similar to the results of the ADANU study in Ghana in 2006 (36) and Jansen study in Colombia in 2015 (37).…”

Objectives: The age of menarche can be different among girls based on region, ethnic, and some individual factors such as body mass index (BMI). Little is known about the menarche age in Kurdish girls. This study was conducted to determine the menarche age and its association to BMI and socioeconomic status among Kurdish schoolgirls. Methods: This was a cross-sectional study conducted on 400 schoolgirls from different secondary and high schools in Sanandaj, northwest of Iran. Multi stage sampling was used to select the study samples. Data were collected using a checklist, which included demographic information and other variables under investigation. SPSS version 20 was used for data analysis. Independent sample t-test, one-way ANOVA, and logistic regression were used for data analysis. The significance level of the tests was considered to be 0.05. Results: The mean and standard deviation (SD) of menarche age was 12.87 ± 1.17 years. About 60.3% of girls had normal BMI and 31%, 6.8%, and 2% of them were underweight, overweight, and obese, respectively. There was a significant relationship between higher BMI (P = 0.02) and menarche age. Based on multivariate analysis, the chance of early menarche in children with higher BMI (≥ 25) was significantly 3.57 times higher than others (P = 0.004). There was no significant relationship between socioeconomic status, physical activity, and birth season, attitude towards menarche, nutritional status, and number of brothers with age of menarche. Conclusions: The results showed a significant relationship between menarche age and BMI. The age of menarche in our region was also different compared to other regions of the globe. The findings of the present study can be used by health policy makers for planning and conducting the interventional programs related to menarche in girls.

“…Daughters whose mothers gained greater than 40 lbs of gestational weight had a 30% increased risk of experiencing menarche before 11 years of age (OR 1.27; CI 1.06-1.56) (Boynton-Jarrett et al 2011). These findings are supported by other studies that report an inverse association between maternal prepregnancy BMI and GWG and age of menarche of their daughters (Shrestha et al 2011, Deardorff et al 2013, Jansen et al 2015, Lawn et al 2018. Both maternal prepregnancy BMI and GWG were inversely associated with daughter's age at menarche and interestingly the associations remained unchanged after adjustment for many confounders, but were attenuated when adjusted for daughter's prepubertal BMI (Lawn et al 2018).…”

It is well established that early life environmental signals, including nutrition, set the stage for long-term health and disease risk – effects that span multiple generations. This relationship begins early, in the periconceptional period and extends into embryonic, fetal and early infant phases of life. Now known as the Developmental Origins of Health and Disease (DOHaD), this concept describes the adaptations that a developing organism makes in response to early life cues, resulting in adjustments in homeostatic systems that may prove maladaptive in postnatal life, leading to an increased risk of chronic disease and/or the inheritance of risk factors across generations. Reproductive maturation and function is similarly influenced by early life events. This should not be surprising, since primordial germ cells are established early in life and thus vulnerable to early life adversity. A multitude of ‘modifying’ cues inducing developmental adaptations have been identified that result in changes in reproductive development and impairments in reproductive function. Many types of nutritional challenges including caloric restriction, macronutrient excess and micronutrient insufficiencies have been shown to induce early life adaptations that produce long-term reproductive dysfunction. Many pathways have been suggested to underpin these associations, including epigenetic reprogramming of germ cells. While the mechanisms still remain to be fully investigated, it is clear that a lifecourse approach to understanding lifetime reproductive function is necessary. Furthermore, investigations of the impacts of early life adversity must be extended to include the paternal environment, especially in epidemiological and clinical studies of offspring reproductive function.

“…There is substantial variability in the timing of menarche across populations and a secular trend toward earlier menarche within countries (8)(9)(10). This suggests that the timing of puberty may be responsive to changes in environmental conditions.…”
