Ability to follow drug treatment with calcium and vitamin D in postmenopausal women with reduced bone mass.
OBJECTIVE
The aim of this study was to evaluate the ability of women with reduced bone mass to follow calcium/vitamin D treatment in relation to prescribed regimen, dose, indication, mode of intake, and the associated factors.


METHODS
A cross-sectional study of postmenopausal women taking medication after bone mineral density diagnosis of osteopenia or osteoporosis was conducted using the MedTake questionnaire. A total of 186 patients attending a menopause clinic were studied. Sociodemographic characteristics, history of comorbid conditions, concomitant use of medication, length of medication use, and ability to follow treatment in relation to prescribed regimen, dose, indication, and mode of ingestion were assessed.


RESULTS
The mean (SD) age of the women analyzed was 61.6 (8.21) years. The mean time since menopause was 16.8 years. Most women reported having difficulty reading, and 79% were white. The ability to follow treatment, evaluated using MedTake, was lower than 60% in most women. Taking the wrong dose was the most frequent error. The only factor associated with inadequate treatment was the use of concomitant medication (odds ratio, 2.32; 95% CI, 1.06-5.08).


CONCLUSIONS
The ability to follow adjuvant calcium and vitamin D treatment for decreased bone mass is low and associated with concomitant use of medication.
