BACKGROUND: Vitamin D is essential for women's health, yet deficiency is widespread among Moroccan premenopausal women.
OBJECTIVES: This study examined vitamin D intake, dietary sources, determinants, and predictors of serum 25-hydroxyvitamin D [25(OH)D3] in 355 women aged 18-49 years in Meknes, Morocco.
METHODS: Intake and sun exposure were assessed with validated questionnaires, and serum 25(OH)D3 was measured by chemiluminescence immunoassay. Multivariable and penalized regression (LASSO) were applied to deseasonalized values.
RESULTS: Median intake was 2.89 µg/day, and fewer than 20% of participants met the 5 µg/day recommendation. Fish (48%), dairy (24.39%), and meat (9.40%) were the main sources. Intake varied by age and residence: women aged 18-25 had significantly lower intakes (p = 0.027), while rural women consumed less than urban women (2.73 vs. 3.18 µg/day, p = 0.014), with inadequacy in 67.70% vs. 32.30% (p = 0.018). In adjusted regression, quartiles Q2-Q4 (1.76-16.60 µg/day) were associated with ~+3 ng/mL higher serum 25(OH)D compared to Q1 (0.20-1.76 µg/day, p < 0.05). Increments plateaued beyond Q2, and deficiency (<20 ng/mL) persisted in all quartiles (>59%, including 64% in Q4), reflecting limited sun exposure and high adiposity. Sun exposure was a strong positive predictor (β = 0.35, p < 0.001), while BMI was inversely associated (β = -0.37, p < 0.001). In LASSO, only sun exposure remained, explaining ~3% of variance.
CONCLUSION: In this population, improving sun exposure (≥20 min/day) should be prioritized, alongside increasing vitamin D intake through richer food sources and fortification, while also addressing obesity, with a focus on women at risk of deficiency.
