Abstract
The objective of the present study is to investigate the relationships between body
composition, nutritional profile, muscular fitness (MF) and bone health in a sample of children
and adolescents from Colombia. Participants included 1118 children and adolescents (54.6% girls).

The objective of the present study is to investigate the relationships between body
composition, nutritional profile, muscular fitness (MF) and bone health in a sample of children
and adolescents from Colombia. Participants included 1118 children and adolescents (54.6% girls).
Calcaneal broadband ultrasound attenuation (c-BUA) was obtained as a marker of bone health.
Body composition (fat mass and lean mass) was assessed using bioelectrical impedance analysis.
Furthermore height, weight, waist circumference and Tanner stage were measured and body mass
index (BMI) was calculated. Standing long-jump (SLJ) and isometric handgrip dynamometry were
used respectively as indicators of lower and upper body muscular fitness. A muscular index score
was also computed by summing up the standardised values of both SLJ and handgrip strength.
Dietary intake and degree of adherence to the Mediterranean diet were assessed by a 7-day recall
questionnaire for food frequency and the Kidmed questionnaire. Poor bone health was considered
using a z-score cut off of ≤−1.5 standard deviation. Once the results were adjusted for age and
Tanner stage, the predisposing factors of having a c-BUA z-score ≤−1.5 standard deviation included
being underweight or obese, having an unhealthy lean mass, having an unhealthy fat mass, SLJ
performance, handgrip performance, and unhealthy muscular index score. In conclusion, body
composition (fat mass and lean body mass) and MF both influenced bone health in a sample of
children and adolescents from Colombia. Thus promoting strength adaptation and preservation in
Colombian youth will help to improve bone health, an important protective factor against osteoporosis
in later life.
