    ObjectiveTo analyse the prevalence of hypovitaminosisD and associated factors in school children and adolescents living in a region of northern Spain.DesignCross-sectional study (convenience sampling).SettingPrimary Health Care.ParticipantsA total of 602 Caucasian individuals (aged 3.1 to 15.4years) were included in the study.Main MeasurementsPrevalence of hypovitaminosisD were calculated (dependent variable). HypovitaminosisD is defined according to the US Endocrine Society criteria: deficiency (calcidiol <20ng/mL), insufficiency (calcidiol: 20-29ng/mL), and sufficiency (calcidiol ≥30ng/mL). Gender, age, body mass index, residence, and season of the year were recorded (independent variables), and their association with hypovitaminosisD was analysed by multiple regression.ResultsThe prevalence of hypovitaminosisD was 60.4% (insufficiency: 44.6%; deficiency: 15.8%). Multivariate analysis showed that factors associated to hypovitaminosisD were being female (OR: 1.6; 95%CI: 1.1-2.3), pubertal age (OR: 1.8; 95%CI: 1.2-2.6), autumn (OR: 9.5; 95%CI: 4.8-18.7), winter (OR: 8.8; 95%CI: 4.5-17.5) and spring time (OR: 13.2; 95%CI: 6.4-27.5), living in urban areas (OR:1.6; CI95%: 1.1-2.2), and severe obesity (OR: 4.4; 95%CI: 1.9-10.3).ConclusionsThere is a high prevalence of hypovitaminosisD in juvenile populations. being female, pubertal age, autumn, winter and spring seasons, severe obesity, and living in urban areas are factors associated to hypovitaminosisD. Consideration should be given to the administration of vitamin supplements and/or the increase in the ingestion of natural vitaminD dietary sources.Copyright © 2017 Elsevier España, S.L.U.
