Vitamin D status of refugees arriving in Canada: findings from the Calgary Refugee Health Program.

OBJECTIVE: To determine the 25-hydroxyvitamin D (25[OH]D) serum levels in refugee women of childbearing age and in refugee children; to compare their 25(OH)D levels with the recommended levels in order to determine the prevalence of deficiency; to compare their 25(OH)D levels with those in the general Canadian population in the appropriate age and sex groups; and to investigate the association of vitamin D deficiency with potential risk factors. DESIGN: Cross-sectional chart review. SETTING: The Calgary Refugee Health Program, an urban family practice that serves newly arrived refugees in Calgary, Alta. PARTICIPANTS: A total of 1217 refugee women and children screened between June 2005 and January 2010. MAIN OUTCOME MEASURES: Serum 25(OH)D values that were measured during initial screening visits. RESULTS: Overall, 1217 of the 1768 eligible participants (69%) had 25(OH)D laboratory values recorded. The mean concentration of 25(OH)D was 52.0 nmol/L (95% CI 50.6 to 53.3 nmol/L). Using the Institute of Medicine guideline for adequate serum vitamin D levels (>50 nmol/L), 61% of women and 42% of children had lower-than-desirable 25(OH)D levels. Considering the Osteoporosis Canada guidelines, 88% of women and 81% of children had lower-than-desirable 25(OH)D levels (<75 nmol/L), and 21% of women and 10% of children were vitamin D deficient (<25 nmol/L). Mean levels of 25(OH)D were significantly lower across all age and sex groupings compared with the general Canadian population (P<.001). Women from the Middle East had lower mean 25(OH)D values (24.6 nmol/L, 95% CI 21.7 to 27.5 nmol/L) compared with women from Asia, Africa, or South America (P<.001). Mean values of 25(OH)D were lower during the winter in children (P=.01) but not in women. Female refugees between the ages of 12 and 19 years old had lower mean values of 25(OH)D than male refugees in the same age group did (P=.01). CONCLUSION: Most refugees had lower-than-desirable vitamin D levels. All age groups studied had lower mean 25(OH)D levels compared with the general Canadian population. Health care providers should be aware of this concern and consider vitamin D supplementation among refugees.

Evaluation of a Mindfulness-Based Stress Reduction (MBSR) program for caregivers of children with chronic conditions.

OBJECTIVES: Given the demands of caring for chronically ill children, it is not surprising that caregivers often experience high levels of chronic stress. A Mindfulness-Based Stress Reduction (MBSR) program may offer relief to these caregivers by providing tools for self-care and heath promotion that otherwise may be lacking. METHODS: MBSR classes were offered without restriction to parents of children attending various clinics at a large urban children's medical centre. Caregivers completed the Profile of Mood States (POMS) and Symptoms of Stress Inventory (SOSI) both before and after program participation. RESULTS: Forty-four caregivers participated in one of seven group MBSR sessions that were offered between August 2001 and February 2004. Most were mothers of children with special needs and various chronic conditions, who had been diagnosed an average of 7 years previous. Prior to the intervention, caregivers reported very high levels of stress and mood disturbance. These decreased substantially over the 8-week program, with an overall reduction in stress symptoms of 32% (p < .001), and in total mood disturbance of 56% (p < .001). CONCLUSIONS: This brief MBSR program for caregivers of chronically ill children was successful in significantly decreasing substantial stress symptoms and mood disturbance. Further studies would benefit from using more rigorous methodology and applying the program to other groups of chronically stressed caregivers.
