“…If inadequate growth is evident then menarche is delayed, and proper growth depends on nutrition. Menarche occurred earlier among those who had achieved adequate growth indicators, including height [31][32][33], weight [32][33][34], vital capacity [32], and arm circumference [33]. Conversely, a study from Bangladesh found that those with physical stunting (thought to be due to inadequate growth from inadequate nutrition) had later menarche than those without stunting [45].…”

“…Environmental causes of early menarche have been more frequently studied than those associated with late menarche, with 15 articles reporting findings related to early menarche vs. 7 for late menarche and 3 studying both early and late menarche. The most commonly studied environmental causes were related to nutrition, adequate food intake, and proper growth parameters (e.g., height, weight) [17,[31][32][33][34]. One study noted that greater childhood growth coupled with high socioeconomic status was associated with in early menarche [35].…”

Menarche is the first occurrence of a woman’s menstruation, an event that symbolizes reproductive capacity and the transition from childhood into womanhood. The global average age for menarche is 12 years and this has been declining in recent years. Many factors that affect the timing menarche in girls could be affected by climate change. A systematic literature review was performed regarding the timing of menarche and four publication databases were interrogated: EMBASE, SCOPUS, PubMed, and Cochrane Reviews. Themes were identified from 112 articles and related to environmental causes of perturbations in menarche (either early or late), disease causes and consequences of perturbations, and social causes and consequences. Research from climatology was incorporated to describe how climate change events, including increased hurricanes, avalanches/mudslides/landslides, and extreme weather events could alter the age of menarche by disrupting food availability or via increased toxin/pollutant release. Overall, our review revealed that these perturbations in the timing of menarche are likely to increase the disease burden for women in four key areas: mental health, fertility-related conditions, cardiovascular disease, and bone health. In summary, the climate does have the potential to impact women’s health through perturbation in the timing of menarche and this, in turn, will affect women’s risk of disease in future.

“…Peak height velocity occurs about 1.2-1.5 years before menarche [26]. To determine the age at peak height velocity assumes that (longitudinal) data are available for about 3-year periods before and after this event [19].…”

Body Composition Assessment in Children and Adolescents

The most variable component of human body composition, fat tissue, ranges from approximately 5% to over 50% of body mass [1]. There has been increasing scientific interest in fat mass largely because of its relationship to health status [2][3][4][5]. However, there are still some difficulties in the accurate estimation of body fat, particularly in children [6][7][8].It is evident that the prediction of fat percentage by skinfolds depends on a range of factors including sex, ethnicity, age and the site of the measured skinfold [7,9,10]. Many studies have recommended that an increase in the number of measurement sites reduces errors and corrects possible differences in fat distribution between individuals within the same age and sex group [4, 11]. Some authors [12,13] have shown that the relationship between skinfold thickness and body fat percentage depends on body size. Furthermore, the dimensions of the body should also be considered in the prediction equations. Studies of body composition based on skinfold measurements show that the sum of skinfolds is more indicative of subcutaneous fat than single skinfolds [14].A small number of investigations have addressed the relationships between skinfold thicknesses and other anthropometric variables and sexual maturity characteristics in children [10,15] and young athletes [16,17]. Generally, investigations on the relationship between biological maturation and anthropometric characteristics of a given population use two different methodologies: correlation analysis or contrasting of maturity groups [17,18]. At all age levels between 6 and 16 years, more mature girls are characterised by larger body

“…There are many publications worldwide that have dealt with anthropometry and body composition among pre-pubertal and pubertal girls (Slaughter et al, 1988;Weststrate and Deurenberg, 1989;Deurenberg et al, 1990;Goran, 1999;Guo et al, 1993;Ramirez, 1993;Ohsawa et al, 1997;Leccia et al, 1999;Morrison et al, 2001a, b;Tahara et al, 2002;Sampei et al, 2003). These investigations have studied body composition among American Whites, African-Americans, Asian-Americans, Hispanics, Dutch, Italians, Japanese, and Chinese prepubertal and pubertal girls.…”

A study on 111 pre-menarcheal (PMG) and 123 menarcheal (MG) Bengalee Hindu girls was undertaken to compare differences in their anthropometric and body composition characteristics. The mean ages of the PMG (12.5 years, SD = 1.2) and MG (12.6, SD = 1.1) subjects were similar. Anthropometric measurements included height, weight, triceps, and calf skinfolds. Two derived indices (body mass index [BMI] and sum of skinfolds) and four body composition measures, percent body fat (PBF), fat mass (FM), fat free mass (FFM), and fat mass index (FMI) were also studied. The mean, 25th, 50th, and 70th percentile values of age at menarche were 12.0, 11.1, 12.0 and 12.9 years, respectively. Results showed that MG had significantly (P < 0.001) higher mean values for all anthropometric and body composition variables. The difference in mean height, weight, and BMI were 10.5 cm, 11.0 kg, and 3.0 kg/m 2 , respectively. The differences between the two groups in mean PBF, FM, FFM, and FMI were 7.7%, 5.1 kg, 5.9 kg, and 2.0 kg/m 2 , respectively. The percent difference (after attainment of menarche) in mean FM and mean FFM were 50.5% and 19.9%, respectively. Multivariate regression analyses revealed that attainment of menarcheal status had significant impact on all four measures of body composition (PBF: P < 0.0001; FM: P < 0.0001; FFM: P < 0.0001; FMI: P < 0.001) independent of BMI. Using BMI as a covariate, results of ANOVA revealed that the mean values of PBF, FM, FFM, and FMI were significantly higher among MG compared with the PMG subjects, even after adjustment for BMI. In conclusion, this study clearly indicated that there existed significant differences in body composition, irrespective of BMI, between MG and PMG Bengalee Hindus. It also demonstrated that relative difference in mean FM was significantly greater, compared to the relative difference in mean FFM, after the attainment of menarche.
