Introduction: Obesity is a global health problem, and it is linked to great number of pathologies both later in life. Childhood is the stage where there is the greatest peak of bone mass growth. With the increase in fat mass there is also an increase in bone mineral density, but the latest studies suggest that the Bone mineral density (BMD) does not increase proportionally to body weight, increasing consequently the risk of fractures. There is a new classification for obese population, classifying them as either metabolically healthy obese (MHO) or metabolically unhealthy obese (MUO) according to their risk of associating metabolic complications. The aim of this study is to find out if there is a statistically significant difference in BMD between the MHO and MUO.
Material and methods: In this study, we used a sample of 96 patients between the age of 6 and 17, who all attended the endocrinology service of the Sant Joan university hospital in Alicante. All of them with a BMI Z-score> 2 SD for their sex, age and reference population. They were classified according to the Homeostasis Model assessment index (HOMA) into MHO and MUO and underwent a DEXA scan, with which their bone mineral content or CMO and their bone mineral density or BMD were calculated.
Results: The 33 patients classified as MUO had a greater BMD and BMC, moreover, they also had a higher IMC Z-score, age, and troncular fat percentage than the 63 patients classified as MHO. In addition, an apportion of the HOMAclassification components (blood glucose and insulin) was made, and they were individually compared with the BMD. The results showed that the scattering graphic that shows the value BMD in relation to blood insulin levels would be the almost equal to the dispersion graphic showing BMD in relation to HOMA, whereas blood glucose would not show any specific statistical pattern.
Discussion: The results show a higher BMD in MUO patients. On the other hand, the association we found between the role of HOMA in BMD, which seems to depend mainly on insulin, could be due to the role of insulin as an activator of osteoblasts
