Indicators of nutritional status and physical activity level as factors associated with the onset of menarche of ten year old girls from Zadar county, Croatia
Objectives: The aim is to determine the differences in nutritional status and level of physical activity (PA) of ten year old menstruating and non-menstruating girls. Methods: On the sample of 208 girls, fourth graders of elementary schools in Croatia, the indicators of nutritional status were measured: body mass index(BMI), body fat % and waist to hip ratio(WHR), while the PA was assessed using PAQ-C questionnaire. Welch´s t-test was applied to establish the differences and multivariate regression analysis was applied to establish the relationships. Results: Menstruating girls have significantly higher body mass (43.42 kg±8.31 vs. 38.64 kg±8.33), waist circumference (68.10 cm ± 9.86 vs. 62.22 cm ± 7.16), hip circumference (80.81 cm ± 7.24 vs. 76.63 cm ± 7.7), BMI (19.70 ± 3.42 vs. 17.74 ± 3.10), body fat % (28.05 ± 7.54 vs. 21.98 ± 7.67) and WHR (0.84 ± 0.06 vs. 0.81 ± 0.05) in comparison to non-menstruating girls, while non-menstruating girls have significantly higher PA level (2.93 ± 0.57 vs. 2.68 ± 0.57). The regression analysis have shown a ignificant relationship between body fat % and the onset of menarche (β=−0.23, SEβ=0.07, p<0.01). Conclusions: Results show differences in the indicators of nutritional status of girls with regard to the status of maturity. Increased nutritional status and body fat % may be indicators of the accelerated developmental tempo and a determinant for the earlier onset of menarche.
