This study aimed to evaluate the relationship between daily dietary intake of riboflavin (DDIR) and impaired lung function associated with dibutyl phthalate (DBP) exposure. The results showed that higher DDIR was associated with less lung function impairment related to DBP exposure, and inhibiting neutrophil recruitment may be the potential mechanism.
This study aimed to evaluate the relationship between the daily dietary intake of riboflavin (DDIR) and impaired lung function associated with dibutyl phthalate (DBP) exposure. Data of 4631 adults in this national cross-sectional survey were included. Urinary mono-benzyl phthalate (MBP) was used to evaluate the level of DBP exposure. The ln-transformed urinary creatinine-corrected MBP (ln(MBP/UCr)) level was used in the statistical models. High DDIR was defined as the DDIR >= 1.8 mg per day. The results of lung function impairment and high monocytes were significantly higher in the highest MBP group compared with the lowest MBP group. A significant interaction between ln(MBP/UCr) and DDIR (P-interaction = 0.029) was detected for the risk of lung function impairment. The risk of lung function impairment (ORquartiles4 vs. 1 1.85, 95% CI, 1.27-2.71; P-trend = 0.018) and high neutrophils (ORquartiles4 vs. 1 1.45, 95% CI, 1.06-1.97; P-trend = 0.018) was significantly higher in the highest vs. the lowest quartile of MBP in participants with low/normal DDIR but not in in participants with high DDIR. The results of this study showed that high DDIR was associated with less lung function impairment related with DBP exposure, and the inhibiting of the neutrophil recruitment might be the potential mechanism.
