BACKGROUND 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…

Vitamin D status and prevalence of hypovitaminosis D in different genders throughout life stages: A Brazilian cross-sectional study
TLDR
Descriptive curves showed that, in both sexes, the mean values of 25(OH) D decreased from the first years of life until adolescence, then slightly increased, and then tended to stabilize during adulthood, which was higher in children and lower in adolescents and women.
Vitamin D and PTH: data from a cross-sectional study in an equatorial population
TLDR
The equatorial population showed low prevalence of vitamin D hypovitaminosis ranging with age bracket, and the insufficient category by Endocrine Society was corroborated by PTH data.
Cardiometabolic risk factors and hypovitaminosis D in adolescents with overweight from a sunny region in northeast Brazil: A cross-sectional study.
BACKGROUND obesity can influence vitamin D levels, which in turn might be associated with cardiometabolic risk factors. OBJECTIVES this study assessed the association between 25-hydroxyvitamin D
Vitamin D insufficiency/deficiency and its association with cardiometabolic risk factors in Brazilian adolescents.
TLDR
A high proportion of adolescents presenting insufficiency/vitamin D deficiency was ssociated with cardiometabolic risk factors, and an evident relationship between the three indicators involved in overweight assessed in this study BMI, WC and AGR was revealed.
Deficiency and Insufficiency of Vitamin D in Women of Childbearing Age: A Systematic Review and Meta-analysis.
TLDR
Although the magnitude of the prevalence of inadequate levels of Vitamin D is uncertain, the evidence suggests that presence of vitamin D deficiency or insufficiency in women of reproductive age can cause moderate to severe problems.
Body composition and nutritional and metabolic parameters in postmenopausal women sufficient, insufficient and deficient in vitamin D.
TLDR
Serum levels of 25-OH-D were negatively correlated with serum levels of triglycerides, total cholesterol and LDL cholesterol, showing an association with an unfavourable lipid profile.
Relationship between BsmI polymorphism and VDR gene methylation profile, gender, metabolic profile, oxidative stress, and inflammation in adolescents.
TLDR
It is concluded that the methylation profile of the VDR gene is not influenced by the different BsmI polymorphism genotypes, and that serum vitamin D and serum markers of oxidative stress and inflammation can modulate this profile.
Adequate sleep duration among children and adolescents: a review of the Brazil's Report Card
TLDR
It can be observed that, because of the wide range of results and the lack of data with national representativeness, the prevalence of sufficient sleep among young people aged below 18 remains undefined in Brazil.
ОСОБЕННОСТИ ВЛИЯНИЯ РАЗЛИЧНЫХ ФОРМ ВИТАМИНА D НА КОСТНО-СУСТАВНУЮ СИСТЕМУ
TLDR
The simultaneous corrections of vitamin D levels are defined as an important component of the compensation of bone disorders in trauma and orthopedic patients and should be considered for long-term work.
Hipovitaminosis D en niños y adultos en un prestador de salud del Uruguay y su relación con el uso de antiepilépticos
Introducción: la hipovitaminosis D se encuentra ampliamente extendida a nivel mundial, con consecuencias clínicas a nivel óseo y extraóseo. Entre los factores que la causan se encuentran los

Hypovitaminosis D in adolescent females – an analytical cohort study in the United Arab Emirates
TLDR
The finding of a high prevalence of hypovitaminosis D in adolescent females in UAE is of serious concern for their health and that of their infants during their reproductive lives.
Hypovitaminosis D and its association with lifestyle factors
TLDR
Serum vitamin D levels of study population were below normal and were associated with female gender, less physical activity, indoor jobs, less sun exposure, higher education and higher socioeconomic class and relatively fair skin complexion.
Association of vitamin D insufficiency with adiposity and metabolic disorders in Brazilian adolescents
TLDR
The results support the negative association among serum 25(OH)D levels and vitamin D intake with non-skeletal outcomes in Brazilian adolescents and Vitamin D fortification of foods and/or the use of vitamin D supplements need to be considered to raise vitamin D Intake in the adolescent population, even in a sunny country like Brazil.
Prevalence of Vitamin D Insufficiency in Brazilian Adolescents
TLDR
The present study suggests that even in a sunny climate like Brazil the prevalence of vitamin D insufficiency in adolescents is high, most likely this is due to low intakes ofitamin D in this group.
Prevalence of vitamin D deficiency during the summer and its relationship with sun exposure and skin phototype in elderly men living in the tropics
TLDR
A high prevalence of vitamin D deficiency among elderly men despite their high sun exposure during the summer months is found and sun index and body mass index were associated positively and negatively, respectively with serum 25(OH)D independently.
Vitamin D deficiency in girls from South Brazil: a cross-sectional study on prevalence and association with vitamin D receptor gene variants
TLDR
The BsmI, ApaI and TaqI wild variants of the VDR gene, as well as the GGT haplotype, were associated with lower vitamin D levels, suggesting that VDR genetic polymorphisms could be linked to higher susceptibility to vitamin D deficiency in a sub-population of children and adolescents.
[25-hydroxyvitamin D concentrations and blood pressure levels in hypertensive elderly patients].
TLDR
The prevalence of inadequate vitamin D concentrations was related with higher blood pressure in elderly patients and greater fish weekly consumption influenced greater 25-hydroxyvitamin D concentration.
Vitamin D deficiency among subfertile women: case-control study
TLDR
Vitamin D deficiency is prevalent among subfertile women and optimization of serum calcium and vitamin D levels is encouraged.
