Abstract:
Objective: To describe the differences of plasma folate concentration and prevalence of folate deficiency in genders and ages in Chinese adults aged 35 to 64 years. Methods: By cross-sectional analysis, plasma folate concentration was measured in 2 545 adults including men and women by microbiological assay. Results: (1) Men tended to have lower plasma folate concentration and higher prevalence of folate deficiency(9.70 nmol/L, 31.0%) than did women(14.2 nmol/L, 12.5%, P=0.001). (2) Men in South have significantly higher plasma folate concentration and lower prevalence of folate deficiency than in North. The difference of plasma folate concentration was not evident between urban and rural area, but evident in North between in winter and spring. There were no significant differences of prevalence of folate deficiency for men between urban and rural areas in both regions. For women, the differences of plasma folate concentration in areas were significant, which were higher in South and urban, and lower in North and rural areas. (3) Plasma folate concentration increased with age in Southern men. A similar trend for others was not significant. Conclusion: Men have lower plasma folate concentration and higher prevalence of plasma folate deficiency than do women. The distribution of plasma folate concentrations in urban and rural areas seems different between men and women.
