the combined national prevalence of obesity in 2012 in school-age children&#44; using the World Health Organization &#40;WHO&#41; criteria&#44; was 34&#46;4&#37; &#40;19&#46;8&#37; and 14&#46;6&#37;&#44; respectively&#41;&#46;<span class="elsevierStyleSup">2 </span>Although the body mass index &#40;BMI&#41; remains the most widely used method for clinical diagnosis of obesity&#44; it is not a measure of body composition because it only provides information about global changes in the body&#44; without specifying the components that are specifically affected in situations of malnutrition and&#47;or obesity&#46;<span class="elsevierStyleSup">3&#44;4</span></p><p class="elsevierStylePara"> There are several ways to indirectly measure adipose tissue&#46; Among these are 2 kinds of impedance analyses&#58; single frequency and multi-frequency&#44; which both calculate lean body mass&#59; however&#44; their accuracy varies with hydration and the presence of body fluids&#44; although they have the advantage of being non-invasive and accessible&#46; Likewise&#44; there are other more sophisticated methods to assess body composition&#58; dual X-ray absorptiometry &#40;DXA&#41;&#44; computerized tomography &#40;CT&#41;&#44; and magnetic resonance imaging &#40;MrI&#41;&#44; with the latter 2 being used for research purposes&#46; Although various methods are available&#44; some have a number of disadvantages&#44; such as low precision and a need for the individual&#8217;s cooperation&#46; This makes it necessary to find an easy&#44; reliable&#44; and economical method that can be used in professional clinical practice&#46;</p><p class="elsevierStylePara"> DXA is a method commonly used to determine bone mineral density&#44; but it also accurately estimates fat mass and fat-free mass&#46;<span class="elsevierStyleSup">5&#44;6 </span>It is relatively fast and safe&#44; providing high accuracy and requiring little patient cooperation&#46;<span class="elsevierStyleSup">7 </span>Thus DXA has some advantages over MrI&#44; such as the relative ease of access and simplicity of measurements&#46;<span class="elsevierStyleSup">8&#44;9</span></p><p class="elsevierStylePara"> This highlights the importance of this study for clinical application in children with and without obesity with respect to body composition by DXA&#44; relating this to BMI and associating the latter with metabolic abnormalities related to excess adipose tissue&#46;<span class="elsevierStyleSup">10 </span>The purpose of this study is to use DXA to determine whether there is any difference in the content of fat mass&#44; lean mass&#44; and bone mineral density in Mexican schoolchildren with and without obesity&#46;</p><p class="elsevierStylePara"><span class="elsevierStyleBold">Material and methods </span></p><p class="elsevierStylePara"> We developed an observational&#44;

In the obese group a mean bone mineral content of 1&#44;094 was found and in the non-obese group of 979&#44; which&#44; although it was not statistically significant &#40;<span class="elsevierStyleItalic">p</span>&#61;0&#46;051&#41; showed a trend toward increased bone mineral content in obese children&#44; which is probably due to dietary and environmental factors &#40;Table 3&#41;&#46; A significant positive correlation was found between BMI and total fat mass in grams calculated by DXA &#40;Table 4&#41;&#46;</p><p class="elsevierStylePara"><img alt="Table 3 Comparison of body composition between 2 groups of children in Monterrey&#44;

most agree that the most suitable method for estimating body fat should be based on anthropometric measures because of its accessibility&#44; simplicity and reproducibility&#44; harmlessness&#44; and low cost&#46; The BMI is an indicator of body fat&#44; but the relationship between BMI and percentage of body fat varies among individuals&#46; Therefore&#44; it is important to distinguish whether the excess weight is truly due to fat or muscle since we must not forget that children who are overweight but do not have excess fat do not have an increased health risk&#46;<span class="elsevierStyleSup">12-15</span></p><p class="elsevierStylePara"> DXA is becoming an extremely useful tool for assessing changes in bone mass&#44; muscle mass&#44; and especially fat mass not only in adults but children and adolescents&#46;</p><p class="elsevierStylePara"> Haroun et al&#46;<span class="elsevierStyleSup">16</span> analyzed body composition in obese and non-obese Ukrainian children analyzing lean mass&#46; Their study showed that lean mass is different in obese and non-obese children&#46; Body water and mineral content are higher in obese children&#46; These results are consistent with our data regarding the analysis of lean mass&#44; where we also found statistically significant differences between the 2 groups&#46; Again&#44; as with fat mass&#44; the trunk had the greatest percentage of lean body mass in both groups&#46; Likewise&#44; boys had the highest amount of lean mass&#46;</p><p class="elsevierStylePara"> The trunk was the area where the greatest amount of fat was found in both groups&#59; this amount showed statistically significant differences between children with and without obesity&#46; These results are consistent with data published in medical literature in studies using the same method to assess body composition&#46;<span class="elsevierStyleSup">17 </span>We found that boys in both groups showed more body fat than girls&#44; while female patients with obesity often have early&#44; accelerated and rapidly progressive puberties compared to their non-obese peers&#44; leading to an earlier presentation of pubertal changes in body composition&#44; the group of female patients in our study had not yet presented pubertal changes&#46; The distribution of fat mass is clinically important because these deposits in the thoracoabdominal region could be predictive in children with diseases such as diabetes and hyperlipidemia&#44; among others&#46;</p><p class="elsevierStylePara"> We found a positive and statistically significant correlation between BMI and fat mass in both groups of Mexican schoolchildren&#44; making it possible to conclude that this index can also be applied to the Mexican population&#46; The results of our study show that BMI is an indicator of adiposity and it correlates with fat mass determined by DXA&#46; These results are consistent with those described in other publications&#46; Pietrobelli et al&#46;<span class="elsevierStyleSup">18</span> found a correlation between BMI and percentage of body fat measured by DXA in ranges of 0&#46;85 and 0&#46;89 for children 5 to 19 years of age&#46;</p><p class="elsevierStylePara"> Leonard et al&#46;<span class="elsevierStyleSup">19</span> mentioned in their research that obesity during childhood and adolescence is associated with increased bone density and body mass&#46; It is also known that estrogen plays a role in female patients who have already submitted their menarche and likewise in pubertal male patients&#59; aromatase converts testosterone to estrogen&#44; and these play an important role in bone mass gain&#46; However&#44; this was not the case in our study as none of the patients had onset of puberty&#46; In our study&#44; the determination of bone mineral content showed no statistically significant difference between the 2 groups&#46; These data do not agree with what is described in medical literature&#44;<span class="elsevierStyleSup">20-22</span> although it is probably due to dietary and environmental factors as described by Jurimae<span class="elsevierStyleSup">23 </span>in Estonia&#44; who conducted a study on the factors affecting bone density and bone mineral content&#46; These factors include age&#44; since 90&#37; of bone mass is reached at age 18 for women and 22 years for men&#44; making those the best ages for evaluation&#59; nutritional status&#44; which should be taken into account since obese patients often have accelerated bone mineralization&#44; with advanced bone age and size above the familiar&#59; and physical activity&#44; with the latter playing an important role in bone density development&#46; Likewise&#44; there are other rare diseases that affect bone mineral density&#44; namely Turner syndrome&#44; Noonan syndrome&#44; Klinefelter syndrome&#44; Kallman syndrome and others associated with hypogonadism&#44; congenital adrenal hyper-plasia&#44; Cushing&#8217;s endogenous syndrome&#44; rickets&#44; renal tubular acidosis&#44; deletions of 22q11&#44; hypo and hyperthyroidism disorders&#44; hormone deficiency and growth resistance&#44; parathyroid disorders&#44; kidney disorders&#44; inactivating and activating mutations of GNAS&#44; use of loop diuretics&#44; bone dysplasias and rheumatic diseases&#46;</p><p class="elsevierStylePara"> By using DXA&#44; we were able to assess its application in children&#46; One of its main advantages is its low radiation dose&#44; plus the pediatric patient is at an age to cooperate comfortably during the procedure&#44; therefore there is no need for sedation and it is very quick&#46; It would be desirable in the future to expand the sample size and classify patients by pubertal stage to establish baseline reference values&#46; It is important to continue studies involving DXA&#44; so that it becomes a useful tool for assessing changes in fat mass&#44; lean mass&#44; and bone mineral content in childhood&#44; to unify reference values&#46;</p><p class="elsevierStylePara"><span class="elsevierStyleBold">Conflicts of interest </span></p><p class="elsevierStylePara"> The authors have no conflicts of interest to declare&#46;</p><p class="elsevierStylePara"><span class="elsevierStyleBold">Funding </span></p><p class="elsevierStylePara"> No financial support was provided&#46;</p><hr></hr><p class="elsevierStylePara"> Received&#58;
