Community pharmacy is the key to improving vitamin D levels

Abstract

Introduction: Vitamin D is an essential micronutrient that participates in the body's fundamental physiological processes. The pharmacist should involve the patient in his medication adherence, leading to a change in the patient's attitude towards his medication and towards his health problem, in order to achieve the pharmacological objective set. Methods: Quasi-experimental multicenter study design with non-probabilistic convenience sampling. A pharmacist-led intervention in health educationwas carried out, divided in two groups, face-to-face interviewand on-line survey, and the results were evaluated 3 months later to observe if there was any change in the patient's health status or in their vitamin D levels. Results: The study was conducted in four pharmacies through face-to-face interviews (n=49 patients) and online surveys (n = 23). Pharmaceutical intervention improved habits of exercise (0.81 ± 1.44 days/week face-to-face interviews vs −0.09 ± 2.35 days/week online surveys (p = 0.048)). In face-to-face interviews, consumption of vitamin D-rich foods was increased (0.55 unit of tuna/week; p = 0.035 and 0.56 unit of avocado/week; p = 0.001) and was improved correct intake of vitamin D supplements (32.5% baseline to 69.8% at 3 months). The increase in 25- hydroxyvitamin D levels (11.5 ng/mL after 3 months (p = 0.021)) was correlated to salmon consumption (0.951; p = 0.013) and the improvement of quality of life was correlated to avocado consumption (1; p < 0.001). Conclusion: There are habits that improve vitamin D production such as increased physical activity, the correct use of vitamin D supplements and the consumption of foods with high vitamin D levels. The role of the pharmacist is crucial, involving the patient in the treatment making aware of the benefits for his/her health status of increasing vitamin D levels.
