Prevalence of vitamin B12 deficiency in healthy Indian school-going adolescents from rural and urban localities and its relationship with various anthropometric indices: a cross-sectional study

摘要: BACKGROUND Micronutrient deficiency is a global health burden, especially among developing countries. The present cross-sectional study aimed to determine the prevalence of vitamin B12 in healthy Indian school-going adolescents, based on area residence, sex and body mass index (BMI). Furthermore, relationship serum concentration with dietary intake anthropometric indices was assessed adolescents from rural urban India. METHODS A total 2403 (11-17 years) National Capital Region areas Haryana, India were selected. Serum concentrations estimated using an electrochemiluminescence immunoassay. Dietary assessments conducted 65% participants (n = 1556) by two 24-h diet recalls. RESULTS population 32.4% (rural: 43.9% versus urban: 30.1%, P < 0.001; male: 34.4% female: 31.0%, P < 0.05; normal weight: 28.1%, overweight: 39.8%, obese: 51.2%, P < 0.001). More than half (51.2%) obese deficient. On multiple linear regression analysis, associated age (β = -0.12, P < 0.05). Among BMI (β = -0.08, P < 0.05) adjusted (β = 0.14, levels found be lower females P = 0.030) males (β: 0.11, P < 0.001) compared their respective contemporaries. CONCLUSIONS Vitamin higher adolescents. Boys had girls. Inverse associations adiposity observed. positively intake.
