Multi-frequency bioelectrical impedance for the prediction of body water compartments: validation in different ethnic groups.

Body weight, body height and impedance at 1 kHz and at 100 kHz were measured in the fasting state in groups of healthy adult males and females from Ethiopia, China, Italy and The Netherlands. Total body water (TBW) and extracellular water (ECW) were determined by deuterium oxide and bromide dilution respectively. TBW/height and ECW/height were calculated as a measure of body build.

Validity of predicted total body water and extracellular water using multifrequency bioelectrical impedance in an Ethiopian population.

Total body water (TBW) and extracellular water (ECW) were measured by deuterium oxide dilution and bromide dilution, respectively, in a group of 24 male and 20 female healthy Ethiopians, living in the capital Addis Ababa. Body weight, body height, skinfolds and total body impedance at 1 and at 100 kHz were also measured. TBW and ECW were predicted from impedance values at 1 and 100 kHz, respectively, using prediction equations developed in a Dutch adult population.

Interrelationship between vitamin A, iodine and iron status in schoolchildren in Shoa Region, central Ethiopia.

A total of 14,740 schoolchildren in seven provinces of Shoa Administrative Region in Central Ethiopia were surveyed for the prevalence of goitre, xerophthalmia and anaemia. Haemoglobin and packed cell volume were assessed in 966 children in one province while an in-depth study was conducted on 344 children in the same province and two others. Goitre, xerophthalmia (Bitot's spots) and clinical anaemia were observed in 34.

Severe vitamin A deficiency in a rural village in the Hararge region of Ethiopia.

A total of 240 children were examined for vitamin A deficiency in a village in Hararge region of Ethiopia. Night blindness, Bitot's spots, corneal xerosis, corneal ulceration and corneal scars were observed in 69, 16, 2, 15 and 14 children, respectively, based on the most severe eye signs. Blood was collected from 76 children with eye signs and 9 other children selected at random.

Goitre in Ethiopia.

A stratified goitre survey was conducted on 35,635 schoolchildren and 19,158 household members in all Regions of Ethiopia except Eritrea and Tigrai. The gross goitre prevalence (mean of male and female values) among schoolchildren and household members was 30.6 and 18.
