Serum levels of vitamin A (VA) and zinc of sixty-one randomly selected preschool children aged 4 to 60 months from Sokoto in the Northwestern Nigeria were investigated. The serum VA was assayed spectrophotometrically by ultraviolet irradiation method while Zn level was determined using atomic absorption spectrophotometer (AAS). The results obtained were analysed by correlation and regression me...

This overview of multiple micronutrients during pregnancy and lactation emphasizes 2 relatively neglected issues. The first is that maternal micronutrient status in the periconceptional period, and throughout pregnancy and lactation, should be viewed as a continuum; too often these 3 stages are treated and discussed separately from both a scientific and a public health perspective. Iron and vit...

The nutritional requirements of older women is an area of great interest because the extended life expectancy leads to an increase in women living into their 80s, 90s, and longer. The recommended dietary allowances (RDAs) and dietary reference intakes (DRIs) are not specific for women living to advanced ages, and little research has been conducted specifically on the micronutrient needs of elde...

INTRODUCTION Data already demonstrated the increased prevalence of obesity in various segments of the population. In this context, bariatric surgery is accepted nowadays as the most effective tool in the treatment and control of morbid obesity. Several studies have evaluated the nutritional status after bariatric surgery, especially mixed by detecting a reduction in food intake of protein, vita...

BACKGROUND Undernourishment and micronutrient deficiencies exacerbate immunosuppression, oxidative stress, acceleration of human immunodeficiency virus (HIV) replication and CD4 T-cell depletion in HIV-infected individuals. MATERIALS AND METHODS The current work reports the serum levels of antioxidant vitamins (vitamins A, C and E) and minerals (Zn, Fe, Cu) in 90 HIV positive subjects attendi...

OBJECTIVE The objective of the current analysis was to explore the association of multiple micronutrients with Hb concentration among pregnant women in a South Asian setting, a topic that has not been adequately explored. DESIGN Sociodemographic, anthropometric and micronutrient status (plasma ferritin, transferrin receptor, retinol, a- and g-tocopherol, folate, vitamin B12, Zn) and Hb concen...

Previous studies have suggested that susceptibility to arsenic toxicity could be influenced by micronutrients, in particular selenium, methionine, and beta-carotene. A case-control study was conducted in West Bengal, India, in a region known to have groundwater arsenic contamination, to determine whether differences in micronutrient status contribute to susceptibility to arsenic-induced skin le...

A deficiency of any of the micronutrients: folic acid, Vitamin B12, Vitamin B6, niacin, Vitamin C, Vitamin E, iron, or zinc, mimics radiation in damaging DNA by causing single- and double-strand breaks, oxidative lesions, or both. For example, the percentage of the US population that has a low intake (<50% of the RDA) for each of these eight micronutrients ranges from 2 to >20%. A level of fola...

BACKGROUND In developing countries, incomplete resolution of anemia with iron supplementation is often attributed to poor compliance or inadequate duration of supplementation, but it could result from deficiencies of other micronutrients. OBJECTIVE Our objective was to assess children's hematologic response to supervised, long-term iron supplementation and the relation of this response to oth...
