Riboflavin Status in a Saudi Population – A Study in Riyadh

Abstract

Riboflavin is essential for several metabolic processes taking place in the human body. A deficiency of riboflavin has been reported to occur at a high prevalence in several populations, particularly in children and adolescents from low-socioeconomic groups. We investigated the riboflavin status in 502 Saudi males and 213 Saudi females using a determination of red-cell glutathione reductase activity in the presence and absence of flavin adenine dinucleotide. The population was grouped according to age and the glutathione reductase activity coefficient (AC) was calculated in each of the groups. An AC value of 1.3 or above was recorded in 38% of the females and 17% of the males. In the female group the lowest percentage was in girls less than 12 years of age, and the highest in the age group 21 -30 years, while among males boys of less than 12 years and men over 30 years of age had the highest percentage. In this paper we report and discuss the riboflavin status, as indicated by the glutathione reductase AC, in the Saudi male and female population in the Riyadh area.

Assessment of thiamin (vitamin B1) and riboflavin (vitamin B2) status in an adult Mediterranean population

“…Our value for the prevalence of vitamin B 2 deficiency in southern Spain (see p. 663) was similar to that reported for a population of independently living elderly Spanish individuals (López-Sobaler et al 2002), and lower than that found for an elderly British population (Bailey et al 1997), elderly Guatemalan individuals (Boisvert et al 1993) and a Saudi population (El-Hazmi & Warsy, 1987).…”

“…Riboflavin plays critical roles in maintaining energy supply and mucous membranes, producing hormones, and aiding fetal development. When deficient, it can cause oral inflammation, dermal dryness, stomatitis, and growth retardation [ 16 , 26 ]. Riboflavin is relatively stable to heat and oxidation but is easily destructive under alkaline conditions and ultraviolet (UV) and visible light exposure [ 27 ].…”

Comparison of the retention rates of thiamin, riboflavin, and niacin between normal and high-oleic peanuts after roasting

“…Riboflavin (vitamin B 2 ) is involved in growth promotion, oral mucosal protection, and in vivo oxidation and reduction. Riboflavin deficiency can cause stunted growth in children, stomatitis, glossitis, and angular stomatitis [14]. Niacin (vitamin B 3 ) governs the oxidation and reduction of nutrients, dilates peripheral blood vessels to promote blood circulation, and reduces cholesterol levels in the body.…”
