Abstract

Objective: The aim of the present study was to investigate vitamin D status among female out-patients in Saudi Arabia during the summer and winter seasons. Design: Data were retrospectively collected using medical record abstraction. Setting: A multidisciplinary hospital in Riyadh between January and December 2009. Subjects: Saudi females (age ≥19 years;n 1556) attending out-patient clinics for various complaints comprised the studied population. The population was subdivided into two groups depending on the date of their visit where blood samples were collected: summer (n 659) and winter groups (n 897). The summer group was further subdivided into premenopausal (age 19–49 years;n 425) and postmenopausal subgroups (age ≥50 years;n 234). Similarly, the winter group was subdivided into premenopausal (n 543) and postmenopausal subgroups (n 354). Serum levels of 25-hydroxyvitamin D (25(OH)D) were measured using HPLC. Results: The prevalence of vitamin D deficiency (25(OH)D <50 nmol/l) was high in both premenopausal and postmenopausal groups (80 % and 68 %, respectively) during the summer, as well as during the winter (85 % and 76 %, respectively). Conclusions: A high prevalence of vitamin D deficiency among Saudi female out-patients was observed throughout the year despite the routine supplementation with 10–20 μg vitamin D 3 for postmenopausal women. Clinicians should seriously consider determining the vitamin D status of Saudi females routinely and prescribing them proper supplementation.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The lack of seasonal deviation in Middle Eastern/African origin populations could be due to the narrow range and low year-round mean 25(OH)D concentrations in these populations (28.5-33.3 nmol/L in winter and summer, respectively).

    “This could be due to the narrow range and low year-round mean 25(OH)D concentrations in these populations (28.5–33.3 nmol/L in winter and summer, respectively) [93].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
