Official title: Study to Evaluate the Efficacy of Fortified Rice on Hemoglobin Levels and Levels of Vitamins and Minerals in Healthy Asian Migrant Workers in Singapore

Status Completed

Clinical Trial Summary

The study is a single center, open label, nutrition intervention study. Healthy adult male working at a Singapore construction site are included if they fulfill inclusion and exclusion criteria. Volunteers receive fortified rice for their daily lunch and dinner each day of the week (i e 14 meals/week) over six months.

Clinical Trial Description

The study is a single center, open label, uncontrolled longitudinal nutrition intervention study. Migrant construction workers of either Bangladeshi or Indian ethnicity from a single dormitory in Singapore volunteer to participate at the study. Only eligible workers are included in the study if they fulfilled all inclusion and exclusion criteria; 20 and 51 years old, a BMI between 17.0 to 27.5 kg/m2, willing to adhere to the study procedure for at least six months, and sign informed consent, are free of current medical and/or chronic/non communicable diseases, no history of heavy smoking or alcohol consumption. The eligible subjects receive fortified rice for their daily lunch and dinner each day of the week (i e 14 meals/week) over six months. The nutrient levels per 100 g fortified rice contain 150 µg vitamin A (Vitamin A palmitate), 0.5 mg vitamin B1 (thiamin mononitrate), 7 mg vitamin B3 (niacin amide), 0.6 mg vitamin B6 (pyridoxine hydrochloride), 1 µg vitamin B12 (cyanocobalamin), 130 µg folic acid, 4 mg iron (ferric pyrosphosphate), and 6 mg zinc (zinc oxide). At baseline and after 6 months of intervention, BMI and vital signs such as blood pressure, pulse and body temperature are collected. Also, 10 ml venous blood is sampled at baseline and after 6 months of intervention and subsequently tested for hemoglobin, serum folate, and serum zinc, serum ferritin and serum vitamin B12 status. In a small subset of the migrant construction workers, an extra 5 ml blood sample is taken for homocysteine testing. ;
