“…In contrast, another study realized in Germany found that serum concentrations of individuals varied according to factors like the seasons, living in an urban or rural environment and the body mass index, in addition to time spent in sunny regions and Our results demonstrate that gender may be a determining factor that is strongly associated with vitamin D deficiency, since female adolescents had higher prevalence than males. Similar results have been found in other studies around the world (25,29). A recent cohort study conducted in the United States showed that in a model adjusted for several variables similar to ours, male participants had higher concentrations of 25 (OH) D over time when compared to females (30).…”

ResumenIntroducción: la hipovitaminosis D es un problema frecuente en el mundo y puede verse influenciada por varios factores. Objetivo: estimar la prevalencia de hipovitaminosis D y factores asociados en adolescentes de una ciudad capital del noreste de Brasil. Métodos: estudio epidemiológico transversal que evaluó a 220 adolescentes de ambos sexos de 15 a 19 años de edad. Se aplicó un cuestionario para evaluar los datos sociodemográficos y de comportamiento. El estado nutricional antropométrico fue evaluado por IMC para la edad. Las concentraciones séricas de 25 (OH) D, PTH y calcio en suero se midieron mediante muestras de sangre. Se identificaron individuos con hipovitaminosis D como aquellos con 25 (OH) D < 30 ng/dl. El análisis de factores asociados con la hipovitaminosis D se realizó mediante Regresión de Poisson simple y multivariante. Resultados: la prevalencia de hipovitaminosis D fue del 57,3%. La población femenina tenía una prevalencia significativamente mayor que la masculina. En el modelo ajustado final, la variable independientemente asociada con la hipovitaminosis D en las mujeres fue la más baja de las concentraciones séricas de calcio, y para los hombres fue el IMC, en el que los adolescentes con sobrepeso/obesidad tenían 2,4 veces más probabilidades de tener hipovitaminosis que los eutróficos. Conclusiones: el presente estudio encontró una alta prevalencia de hipovitaminosis D en la población analizada, especialmente en adolescentes. Además, se encontró que los factores asociados de forma independiente con la hipovitaminosis D fueron el sobrepeso/obesidad en los niños y concentraciones bajas de calcio en las niñas. AbstractBackground: Hypovitaminosis D is a frequent problem in the world and can be influenced by several factors. Objective: To estimate the prevalence of hypovitaminosis D and associated factors in adolescent students of a capital city of northeastern Brazil. Methods: Cross-sectional epidemiological study assessing 220 school adolescents of both sexes aged 15 to 19 years. A questionnaire was applied to assess sociodemographic (skin color, mother's education and receiving social benefits) and behavioral data (number of hours of sleep per day, sun exposure, physical activity and dietary vitamin D intake). Anthropometric nutritional status was assessed by BMI (body mass index) for age. Serum 25 (OH) D concentrations, PTH and serum calcium were measured by blood samples. We identified individuals with hypovitaminosis D as those with 25 (OH) D < 30 ng/dL. The analysis of factors associated with hypovitaminosis D was performed by simple and multivariate Poisson Regression. Results: The prevalence of hypovitaminosis D was 57.3%. The female population had a significantly higher prevalence than the male. In the final adjusted model, the variable independently associated with hypovitaminosis D in females was the lowest serum calcium concentrations, and for males it was BMI, in whic...

“…Indeed our observation that adolescent residing in Dubai have much higher percentage of vitamin D deficiency than expected, has been seen before by a group of investigators in Al-Ain ,United Arab Emirate, they found majority of young Emirati girls attending public school, aged between 11-18year, were deficient in Vitamin D [21].…”

“…This study supports the previous results of very high Hypovitaminosis D in U.A.E. females [3,19,28]. Other significant result noticeable is that dietary Vitamin D is not linked to Vitamin D status in general population of Emarati females from Abu Dhabi, and this was also observed in previous studies in university sample from Abu Dhabi [2], hence supplement use might me be the best way to achieve Vitamin D sufficient levels in this temperate country females.…”
