dc.description.abstractBackground Vitamin deficiency is a cause of health related problems in elderly people. The aims were to study associations between vitamin B6 (B6) and diseases (primarily functional gastrointestinal disorders) in elderly people in nursing homes, the prevalence of B6 deficiency and factors associated with B6 deficiency. Methods This cross-sectional study included residents in nursing homes. Demographics, nutritional status (Mini Nutritional Assessment, MNA® ), physical activity, activity of daily living (Katz Index), dietary habits, use of drugs, and psychiatric and somatic diseases were recorded. A blood sample was collected for haematological and biochemical screening, including B6 (p-PLP); p-PLP values < 20 nmol/l indicates B6 deficiency. The results are given as mean (SD). Results Sixty-one residents (men/women: 22/39) with an age of 85.3 (6.8) years and BMI 25.7 (4.5) kg/m2 were included. Malnutrition and risk of malnutrition were present in 11.5% and 61% respectively. Dietary intake of B6 (mg/day) in men and women were 1.60 (0.30) and 1.18 (0.31) (recommended 1.6 and 1.2 respectively), and 14 (23%) used B6 supplements. Median p-PLP was 20.7 (range <4.0-175.8), 30 subjects (49%) had B6 deficiency. B6 deficiency was associated with old age, low s-alanine aminotransferase and s-albumin, elevated s-homocysteine and inactivity (p-values 0.01-0.03). There were no clinically significant associations between B6 deficiency and somatic or psychiatric disorders, and B6 deficiency was not observed in subjects given B6 supplements. Conclusions Half of the residents had vitamin B6 deficiency. Vitamin supplement was effective prophylaxis for deficiency and should be recommended to all elderly people in nursing homes.nb_NO
