Nutritional parameters in urban and rural Zulus

Anthropometric, biochemical and haematological nutritional parameters were measured in 103 (65 men, 38 women) Durban Zulu adults (urban) and 109 (41 men, 68 women) Tugela Ferry Zulu adults (rural). Men conformed to an ideal weight for height whereas women were 18% overweight in Tugela Ferry and 30% so in Durban. Mean arm muscle circumference in men was between the 10th and 20th centiles. Other nutritional parameters were similar to those accepted internationally as normal. In particular the serum albumin level was normal in both urban and rural Zulus. There was little change in the parameters with age except that hand grip as measured by dynamometry fell with age (P less than 0,05). Serum albumin levels fell with age in women (P less than 0,01) but not in men. Nine mothers of babies suffering from kwashiorkor showed normal nutritional profiles.
