Fat mass index and hip bone mineral density in a group of Lebanese adolescents and young adults

Objective: The main aim of this study was to explore the relationship between fat mass index and hip bone mineral density in a group of Lebanese adolescents and young adults

Methods and Results: 91 females and 111 males [aged 13 to 30] participated in this study. Body com- position [lean mass, fat mass and bone mineral con- tent] and bone mineral density [BMD] of whole body [WB], total hip [TH] and femoral neck [FN] were assessed by dual-energy X-ray absorptiometry [DXA]. Weight and height were measured, and body mass index [BMI], lean mass index [LMI] and fat mass index [FMI] were calculated. Body weight, BMI, lean mass and LMI were positively correlated to TH BMD and FN BMD in females and males. Fat mass and FMI were positively correlated to TH BMD and FN BMD in females but not in males

Conclusion: This study suggests that FMI is a positive determinant of TH BMD and FN BMD in adolescent girls and young women but not in adolescent boys and young men while LMI is a positive determinant of TH BMD and FN BMD in both genders
