“…Dans notre population, moins de 5 % des filles dé claraient être en surpoids ou obè ses selon les normes de l'International Obesity Task Force [16] à partir de l'IMC calculé d'aprè s la taille et le poids dé claré s. Cette fré quence justifie de ne pas prendre en compte cet effet potentiel dans nos estimations. L'âge moyen à la mé narche calculé dans notre é tude é tait proche des estimations disponibles dans les autres pays dé veloppé s qui variaient de 12,3 ans en Grè ce [17] à 13,3 ans en Finlande [18] pour les é tudes les plus ré centes.

“…For example, European data collected in the 1990s showed mean ages of menarche that are older than those from the US data (eg, menarche mean ages ranged from 13.0 to 13.4 years in Denmark, 83,84 ϳ13.2 years in Norway 85 and Sweden, 86 and 12.6 -12.9 years for white girls in the United States 3,5,46,47 ). Urban-rural differences in the mean age of menarche have also been observed within a country 87 ; however, it is not possible to conclude definitively that mean age at menarche is different among countries without an analysis of the study design comparability.…”

Examination of US Puberty-Timing Data from 1940 to 1994 for Secular Trends: Panel Findings

Whether children, especially girls, are entering and progressing through puberty earlier today than in the mid-1900s has been debated. Secular trend analysis, based on available data, is limited by data comparability among studies in different populations, in different periods of time, and using different methods. As a result, conclusions from data comparisons have not been consistent. An expert panel was asked to evaluate the weight of evidence for whether the data, collected from 1940 to 1994, are sufficient to suggest or establish a secular trend in the timing of puberty markers in US boys or girls. A majority of the panelists agreed that data are sufficient to suggest a trend toward an earlier breast development onset and menarche in girls but not for other female pubertal markers. A minority of panelists concluded that the current data on girls' puberty timing for any marker are insufficient. Almost all panelists concluded, on the basis of few studies and reliability issues of some male puberty markers, that current data for boys are insufficient to evaluate secular trends in male pubertal development. The panel agreed that altered puberty timing should be considered an adverse effect, although the magnitude of change considered adverse was not assessed. The panel recommended (1) additional analyses of existing puberty-timing data to examine secular trends and trends in the temporal sequence of pubertal events; (2) the development of biomarkers for pubertal timing and methods to discriminate fat versus breast tissue, and (3) establishment of cohorts to examine pubertal markers longitudinally within the same individuals.

Background-Atherosclerosis development might be delayed or prevented by dietary measures. The aims of the present study were to evaluate the effect of low-saturated-fat, low-cholesterol dietary counseling on fat intakes, growth, serum cholesterol values, and pubertal development in children and adolescents. Methods and Results-In the randomized prospective Special Turku Coronary Risk Factor Intervention Project (STRIP), a low-saturated-fat, low-cholesterol diet was introduced to intervention infants (nϭ540) at 7 months of age, and control children (nϭ522) received an unrestricted diet. Dietary intakes, serum cholesterol values, somatic growth, and development were followed up throughout childhood and adolescence. Saturated fat intakes, serum total cholesterol, and low-density lipoprotein cholesterol values were lower (PϽ0.001) in the intervention than in control children during the 14 years, whereas high-density lipoprotein cholesterol values in the 2 study groups showed no difference. Boys had lower total and low-density lipoprotein cholesterol concentrations than girls throughout childhood (PϽ0.001), and the intervention effect on serum cholesterol concentration was larger in boys than girls. The 2 study groups showed no difference in growth, body mass index, pubertal development, or age at menarche (median, 13.0 and 12.8 years in the intervention and control girls, respectively; Pϭ0.52). The cholesterol values decreased as puberty progressed. Mean concentrations of total and high-density lipoprotein cholesterol decreased from Ϸ4.5 and Ϸ1.4 mmol/L, respectively, in Tanner stage 1 (prepubertal) boys to Ϸ3.9 and Ϸ1.1 mmol/L in Tanner stage 4 (late pubertal) boys. Conclusions-Repeated dietary counseling remains effective in decreasing saturated fat and cholesterol intake and serum cholesterol values at least until 14 years of age. Puberty markedly influences serum cholesterol concentrations.
