[Hypovitaminosis D: its high prevalence in elderly outpatients in Barcelona. Associated factors].

Abstract

BACKGROUND

Hypovitaminosis D is a frequent finding in the elderly of northern countries. In Spain because of high sun irradiation it has been traditionally considered that hypovitaminosis D is not a frequent problem. In this study we have evaluated the prevalence of hypovitaminosis D in the elderly and the associated factors.

SUBJECTS AND METHODS

All individuals older than 65 years attending a primary care unit (november 1995-march 1996) and without any disease modifying vitamin D status were included. The following data were recorded: age, gender, height, weight, white and red cell counts, glycaemia, serum ions, albuminemia, plasma creatinine, creatinine clearance, urinary creatinine and calcium, parathyroid hormone (PTHi), calcidiol and calcitriol. Sun exposure and fish ingestion was also determined by questionnaire.

RESULTS

127 individuals were evaluated (age: mean [SD] 74.8 [6.4] years; 47 men, 37.0%). Forty-four subjects (34.6%; CI 95%: 26.3-42.9%) had calcidiol levels < or = 10 ng/ml, 15 (11.8%; CI 95%: 6.2-17.4%) low values of calcidiol, and 13 (10.2%; CI 95%: 4.9-15.5%) high PTHi values. Subjects with hypovitaminosis D (calcidiol levels < or = 10 ng/ml) were mainly women, older, short stature, had a lower values of body surface, albuminemia, phosphatemia, creatinine clearance, sun exposure and fish intake and higher PTHi levels. In the logistic regression model, hypovitaminosis D was positively associated with age and negatively with sun exposure, albuminemia, height and phosphoremia.

CONCLUSIONS

Hypovitaminosis D is a very frequent finding in Spanish elderly people. Its presence is independently associated with age (positively) and sun exposure, serum albumin, height and phosphoremia (negatively).
