The aim of the present study was to examine (a) the relationship of body fat (BF) assessed by bioimpedance analysis (BIA) and skinfold thickness (SKF) and (b) the variation of BF by age depending on the assessment method. Participants were 32 women and 134 men recreational marathon runners, who were tested for BF using both assessment methods (BIA and SKF). Rc between BIA and SKF assessment methods was 0.803 (95% CI; 0.640, 0.897) in women and 0.568 (95% CI; 0.481, 0.644) in men. A large main effect of the assessment method on BF was observed ( p < 0.001 , η 2 = 0.156 ) with SKF presenting higher BF than BIA by 2.9%. The difference between SKF and BIA was 3.9 ± 2.7 % (95% confidence intervals, CI; 3.4; 4.3, p < 0.001 ) in men, whereas no difference was found in women ( − 0.9 ± 2.9 % ; 95% CI; -1.9; -0.2, p = 0.101 ). BF correlated with age with small magnitude (BIA, r = 0.18 , p = 0.036 ; SKF, r = 0.23 , p = 0.007 ) in men, i.e., the older the age, the higher the BF. A similar trend of moderate magnitude was observed in women for BIA ( r = 0.45 , p = 0.011 ), but not for SKF ( r = 0.33 , p = 0.067 ). In conclusion, practitioners involved in the training of recreational runners would be advised to consider that BIA elicits a lower BF value than the SKF method in men.

The Difference

Based on nutritional status, women who are obese have a higher risk of menstrual cycle disorder compared to women with normal nutrient status. The purpose of the study was to promote the difference in the prevalence of menstrual patterns based on nutritional status in teenagers in midwifery school, Universitas Muslim Indonesia. This research used cross-sectional design. Samples in this study were 56 people. The data were collected by filling questionnaires and direct measurements of nutritional status based on the per cent of body fat using a Bioelectrical Impedance Analysis (BIA) method, then analysed using Chi-Square. The results of this study showed 56 young women who had an average body fat per cent of 29 (51.8%). As the results, it indicated a significant relationship between the per cent of body fat with the long disorders period of menstruation (p = 0.01). Whereas the per cent of body fat with menstrual cycles did not show the prominent relationship (p = 0.33) as well as between per cent body fat with painful menstruation which there is no significant relationship (p = 0.24). Besides, the situation can be caused by several factors such as changes in hormone and stress.

Tujuan penelitian adalah memgetahui perbedaan prevalensi gangguan pola menstruasi, berdasarkan status gizi pada remaja di program D-III Kebidanan UMI. Desain penelitian ini adalah cross sectional. Sampel penelitian ini adalah 56 orang. Data dikumpulkan melalui pengisian kuesioner dan pengukuran langsung status gizi berdasarkan persen lemak tubuh menggunakan metode Bioelectrical Impedance Analysis (BIA). Data dianalisis menggunakan uji Chi square. Hasil penelitian ini menunjukkan bahwa dari 56 remaja putri yang memiliki persen lemak tubuh normal sebanyak 29 (51,8%). Terdapat hubungan yang signifikan antara persen lemak tubuh dengan gangguan lama menstruasi (p=0,01), sedangkan antara persen lemak tubuh dengan siklus menstruasi tidak ada hubungan signifikan (p=0,33) begitupun juga dengan antara persen lemak tubuh dengan nyeri haid tidak ada hubungan yang signifikan (p=0,24) hal ini bisa disebabkan oleh beberapa faktor antar lain perubahan hormon dan stress.

Age And Sex

In 1229 subjects, 521 males and 708 females, with a wide range in body mass index (BMI; 13.9–40.9 kg/m2), and an age range of 7–83 years, body composition was determined by densitometry and anthropometry. The relationship between densitometrically-determined body fat percentage (BF%) and BMI, taking age and sex (males =1, females = 0) into account, was analysed. For children aged 15 years and younger, the relationship differed from that in adults, due to the height-related increase in BMI in children. In children the BF% could be predicted by the formula BF% = 1.51xBMI–0.70xage–3.6xsex+1.4 (R2 0.38, SE of estimate (see) 4.4% BF%). In adults the prediction formula was: BF% = 1.20xBMI+0.23xage−10.8xsex–5.4 (R2 0.79, see = 4.1% BF%). Internal and external cross-validation of the prediction formulas showed that they gave valid estimates of body fat in males and females at all ages. In obese subjects however, the prediction formulas slightly overestimated the BF%. The prediction error is comparable to the prediction error obtained with other methods of estimating BF%, such as skinfold thickness measurements or bioelectrical impedance.
