Abstract:
Objective:To explore the correlation between serum vitamin D level and glucose and lipid metabolism among primary and middle school students in Inner Mongolia, so as to providing a scientific basis for guiding rational vitamin D supplementation among primary and middle school students in Inner Mongolia Region.
Methods:A total of 2 206 students of primary and middle school students from 8 counties (districts) in Inner Mongolia were enrolled for a questionnaire survey, physical examination, and laboratory test by a multi stage stratified random sampling approach.The levels of fasting blood glucose, blood lipid and other related indexes with different vitamin D levels were analyzed, and their correlation was further discussed.
Results:The deficiency and insufficiency rates of vitamin D among primary and middle school students were 33.2% and 42.8%, respectively, and the suitable rate was 24.0%. The body mass index (BMI) and waist height ratio (WHtR) of the vitamin D deficiency group [(22.87±7.41) kg/m 2 , 0.46±0.08)]were higher than the insufficiency [(20.59±8.00)kg/m 2, 0.44±0.09)] and suitable group [(18.01±7.38)kg/m 2, 0.43 ±0.08)] ( P <0.05). Compared with the vitamin D suitable group [(3.87±0.85) mmol/L], the total cholesterol (TC) level in the deficiency group [(3.73±0.67)mmol/L] decreased, with a statistically significant difference ( P <0.05). The levels of high density lipoproteins (HDL) in the vitamin D insufficiency[(1.40±0.33)mmol/L] and deficiency groups [(1.34±0.31)mmol/L] were lower than the suitable group [(1.48±0.34)mmol/L], with a statistically significant difference ( P <0.05). The detection rate of hyperuricemia (HUA) in the vitamin D deficiency group (22.95%) was higher than the suitable group (17.20%), with a statistically significant difference ( P <0.016 7). Pearson correlation analysis showed that vitamin D was negatively correlated with BMI and WHtR ( r =-0.23, -0.11), and positively correlated with TC and HDL level ( r =0.06, 0.16) ( P <0.05).
Conclusions:The deficiency and insufficiency rates of serum vitamin D among primary and middle school students in Inner Mongolia are high which are associated with several indicators of blood lipids. Therefore, it is recommended to supplement vitamin D preparations in moderation in daily life.
