Impact of Fortified Rice on Workers' Nutrition Status

February 4, 2021 updated by: DSM Nutritional Products, Inc.

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

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. Nutrition status in blood is measured at baseline and after six months of fortified rice consumption.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed 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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
