Vitamin D Knowledge, Awareness, and Attitudes of Adolescents and Adults: A Systematic Review.

INTRODUCTION: The aims of this systematic review were 2-fold: (1) evaluate the effect of vitamin D educational interventions on serum 25-hydroxyvitamin D (25-OHD) concentration in adolescents (aged 10-19 years) and adults, and (2) assess the association between serum 25-OHD concentration and vitamin D knowledge, awareness of vitamin D deficiency risk, and attitudes toward behaviors associated with acquiring vitamin D. METHODS: Medline, CINAHL, Embase, and SPORTDiscus were systematically searched for studies reporting associations between serum 25-OHD concentration and vitamin D knowledge, awareness, and attitudes. Results were summarized narratively. Effect sizes were calculated when data were available. RESULTS: Eight studies reported experimental effects (2 randomized controlled trials, 1 cluster randomized trial, 4 quasi-experiments, 1 clinical audit), and 14 reported cross-sectional associations. Seven of 8 interventions reported no effect of educational interventions on serum 25-OHD concentration. A slight majority (53%; κ = 19) of studies reported statistically significant associations between serum 25-OHD concentration and vitamin D knowledge and attitudes. IMPLICATIONS FOR RESEARCH AND PRACTICE: The few educational interventions employed to increase serum 25-OHD concentration lack effectiveness. Future studies may use randomized controlled trial designs, enroll those at risk for vitamin D insufficiency and underrepresented in the literature, increase the salience of the information to the target population, and include safe sun exposure recommendations.

Alleviating diabetes distress and improving diabetes self-management through health coaching in a primary care setting.

Considering the rising global burden of diabetes and its complications, effective interventions for addressing barriers to diabetes self-management are needed. Diabetes distress, a psychological barrier to diabetes self-management, has become increasingly recognised in the literature, but effective and feasible ways of addressing it in routine primary care settings are not known. We present the case of a middle-aged non-Hispanic white American woman with poorly controlled diabetes (haemoglobin A1c (HbA1c): 13.9%) and elevated diabetes distress (baseline Diabetes Distress Scale Score: 2.53) who participated in a health coaching intervention. After the 5-month programme, which included eight 45 minute long sessions with a trained health coach, the patient achieved and sustained a 0.8-point reduction in diabetes distress, an improvement in insulin adherence and a 3.6-point reduction in HbA1c. This case demonstrates a novel approach to managing diabetes distress that entails providing patients a safe, nonjudgemental space to express their feelings and explore challenges with diabetes self-management.
