Cardiorespiratory fitness in males, and upper limbs muscular strength in
females, are positively related with 25-hydroxyvitamin D plasma
concentrations in European adolescents: the HELENA study
Περίληψη:
Background: High prevalence of vitamin D insufficiency (<75 nmol/l) has
been previously reported in European adolescents. Vitamin D deficiency
has been related to physical fitness and adiposity but it is not clearly
known whether this relationship applies to growing children and
adolescents.
Aim: To determine how body composition and physical fitness are related
to 25-hydroxyvitamin D [25(OH) D] concentrations in European
adolescents.
Design: The HEalthy Lifestyle in Europe by Nutrition in Adolescence-CSS
study was a multi-centre cross-sectional study.
Methods: Plasma 25(OH) D, body composition and physical fitness measures
were obtained in 1006 European adolescents (470 males) aged 12.5-17.5
years. Stepwise regression and ANCOVA were performed by gender using
25(OH) D as dependent variable, with body composition, physical fitness
as independent variables controlling for age, seasonality and latitude.
Results: For males, maximum oxygen consumption (VO2max) (B = 0.189) and
body mass index (BMI) (B = -0.124) were independently associated with
25(OH) D concentrations (both P < 0.05). For females, handgrip strength
(B = 0.168; P < 0.01) was independently associated with 25(OH) D
concentrations. Those adolescents at lower BMI and high fitness score
presented significant higher 25(OH) D concentrations than those at lower
fitness score in the other BMI groups (P < 0.05).
Conclusions: Cardiorespiratory fitness and upper limbs muscular strength
are positively associated with 25(OH) D concentrations in male and
female adolescents, respectively. Adiposity in males and low fat free
mass in females are related to hypovitaminosis D. The interaction
between fitness and BMI has a positive effect on 25(OH) D
concentrations. Therapeutic interventions to correct the high rates of
vitamin D deficiency in adolescents should consider physical fitness.
