In this context, hypovitaminosis D has been a frequent finding among the elderly individual, especially in those institutionalized. The objective of the present study was to evaluate the vitamin D status and associated factors in elderly living in nursing homes (NH) in Natal/RN. A cross-sectional study was carried out with 153 elderly individuals living in nine Nursing Homes (NH) of the city of Natal-RN, Brazil between 2012 and 2015. The theoretical model was constructed according to the Social Determinants of Health (SDH), being chosen as dependent variable the 25 hydroxyvitamin D [25 (OH)D] level and as independent variables: type of NH, institutionalization time and schooling (distal layers); age, sex, skin color, body mass index, calf and abdominal circumference, physical activity, mobility, dietary intake of vitamin D and calcium, use of vitamin D supplementation, use of antiepileptics (proximal layers); and season (transverse layer). The concentration of 25 (OH) D in serum was determined by chemiluminescence. The elderly diagnosed with "insufficient" status when they presented values less than or equal to 29 ng/mL. Food consumption data were obtained by direct weighing of food method. Pearson's Chi-square test was used to ascertain the associations between variables. The mean age of the participants was 81.7 (9.2) years, with a predominance of females (78.4%). The majority of the elderly lived in NH (68%) and 54.7% of the elderly individuals were white. A high dietary inadequacy of vitamin D (95.4%) and calcium (79.7%) was observed, and 71.2% of the population presented hypovitaminosis D (23.9 ng / mL; CI: 22.81 - 26.13 ). Among other characteristics, 70.2% did not practice physical activity, 86.9% had some degree of mobility and 66.7% had severe cognitive impairment. Concentrations of 25 (OH) D were not significantly associated with SDH. The health care of the elderly should focus on modifiable risk factors and intervention with vitamin D, considering the aging process.Acesso AbertoVitamina DIdososInstituição de longa permanênciamasterThesisCNPQ::CIENCIAS DA SAUDE::NUTRICAO
