Cutaneous Synthesis

As a number of seasonal factors affect cutaneous synthesis of vitamin D, especially in young children, our objective was to verify if winter and summer vitamin D intakes in Quebec preschoolers reach the adequate intake of 5 µg/day. A three-month retrospective food frequency questionnaire and a 24-hour food recall were used with parents of 98 children (mean age 56 months) in summer and of 72 of these children (mean age 65 months) in winter. To ensure completeness of data, vitamin D content of foods not covered in the Canadian Nutrient File was taken from other sources. According to the food frequency questionnaire, total vitamin D intakes were 9.7 ± 4.3 g/day in summer and 11.6 ± 4.8 g/day in winter. Only 10% of children in summer and 7% in winter had an intake below 5 µg/day. The 24-hour food recall vitamin D intake estimate was lower (summer 7.0 ± 3.8 µg/day, winter 7.2 ± 4.2 µg/day). This difference could be partly due to a discrepancy in the estimation of multivitamin supplement intake. However, according to both estimates, vitamin D intakes appeared generally adequate in this sample of Quebec preschoolers.

Abstract Objective The aim of the present study was to develop and validate a vitamin D food frequency questionnaire (FFQ) for assessment of dietary vitamin D intake in healthy adults in England, UK. Design: The current study assessed the agreement between a four-day food diary (4d-FD) and a new vitamin D FFQ to measure dietary intake of vitamin D. Dietary intake was estimated using Nutritics dietary analysis software and Spearman’s and Bland-Altman tests were utilised to assess correlation and agreement, respectively. Participants also provided a blood sample for plasma analysis of vitamin D concentrations. Setting: Home setting. Participants: Fifty participants were recruited to the study from the University of Chester and vicinity. Results: Results showed a strong correlation between vitamin D intake recorded by the FFQ and the 4d-FD (r = 0.609; P < 0.0001) within 95% limits of agreement. Furthermore, a significant correlation between plasma 25(OH)D concentrations and vitamin D intake measured by the FFQ (r = 0.290, P = 0.041) and the 4d-FD (r = 0.360, P = 0.01) was observed. Conclusion: Our analysis suggests this FFQ is a useful and rapid tool for researchers and health professionals to assess vitamin D dietary intakes in healthy adults in the UK.
