“…Ethnic differences in the age of onset of puberty have been noted in both girls and boys 56 57. These differences add to the overall variation in pubertal timing when looking at large groups of mixed ethnic background.…”

“…The age range of participants was 11 to 13 years old and their mean age was 12.16 ± 0.74 years. Given that previous studies proposed the age of 12 as the best age for teaching puberty health [31] and considering that the mean age of the onset of menstrual cycle is reported to be 13 years old in Iran [31,32], sixth grade primary school girls were selected as participants. The inclusion criteria were: having had at least three menstrual periods and inclination for participation in the study.…”

Background: As children approach adolescence, they focus increasingly on their appearance and physical attraction due to teenage body-image. Teaching the concepts of adolescent health changes an individual's attitudes towards parts of the body. The health belief model (HBM) is one of the significant pedagogic models in health education. According to this model, the individual's decision and motivation for adopting healthy behaviors depends on three separate categories "personal perception, adaptive behaviors, and probability of performing that action or behavior". This study investigated the effect of teaching puberty health concepts on the basis of a HBM on perceived body image in female adolescents. Methods: A quasi-experimental research design was used in the study. This study was conducted with 60 sixth grade girls in state elementary schools in Yazd, Iran, that were selected with cluster sampling method and assigned randomly into experimental and control groups. The experimental group were educated in the school during eight 45-min sessions based on the HBM, whereas the control group were educated using the traditional lecturing method. The data were collected with demographic and self-body image questionnaires completed before and after intervention. The data were analyzed with SPSS16 using analysis of covariance (ANCOVA). Results: The mean age of the participants was 12.16 ± 0.74 years. The findings showed that "perceived body image" and "students' self-attitude" improved significantly after intervention; yet, no significant difference was found between the subscales "attitudes towards weight" and "satisfaction with various parts of the body". Conclusion: The results of the study confirmed the efficacy and efficiency of teaching puberty health on the basis of the HBM on improving perceived body image in female adolescents.

“…Many studies have shown the earlier onset of puberty especially in girls, but the age of menarche has not significantly changed. Racially different data has been shown in various studies [2][3][4]. Therefore, each country should have its own national reference data for use in clinical practices and for other researches in this area.…”

Pubertal growth in normal Thai children: a longitudinal study

et al. 2010

Background: Pubertal growth data in Thai children has been reported as cross-sectional studies. There is no longitudinal study in Thai children. Objective: Investigate the longitudinal growth data in normal Thai children including the relationship between age at pubertal onset and other growth parameters. Material and method: Eighty-eight normal children (44 boys, 44 girls) were longitudinally assessed for the growth and puberty until they reached their final adult height. Pubertal staging was assessed by the Tanner method. Results: Mean age of pubertal onset was 10.2 ± 1.2 years for girls and 12.2 ± 1.0 years for boys. Total pubertal height gain was 18.3 ± 4.0 cm for girls and 22.3 ± 4.4 cm for boys. Total pubertal height gain had a negative correlation with age at pubertal onset for girls, but not for boys. Conclusion: The onset of puberty was not much changed from previous studies. Girls with early puberty had a higher pubertal height gain. This might be due to a compensatory mechanism. These longitudinal growth data can be used as a reference in clinical practices for Thai children.
