The results of a cross-sectional anthropometric survey of Sudanese children up to the age of thirteen years and six months is reported. Children in whom a quick clinical examination revealed pathology were excluded, as were children who did not have a true birth certificate. Height, weight and mid-arm circumference were measured in all children, head and chest circumference were measured in children up to the age of 5 years and 6 months. Skinfold thickness at biceps, triceps, subscapular and suprailiac sites were measured in children above the age of 30 months. The children were found to be shorter and lighter, and to have less subcutaneous fat than British children. The findings are also compared with those from other African populations. Comparison with a survey performed in the same village seven years earlier reveals that the heights and weights of the children have hardly changed despite a considerable improvement in economic status. The children have a lower weight for height than British and other African populations.
The results of a mixed cross-sectional and longitudinal anthropometric survey of Sudanese children up to the age of sixteen years are reported. Weight velocity, height velocity, mid arm circumference velocity, and mid arm muscle circumference velocity, and the age at which 50% of females have reached menarche have been calculated. Growth velocities are lower than for English children and the puberty growth spurts occurs about one year later in Sudanese than in English children
The data collected in a mixed cross-sectional longitudinal survey of children in a village in rural Khartoum, Sudan, were analysed in order to identify age-independent anthropometric indices. The mean values of weight/height, weight/height, mid arm circumference, mid arm fat area and triceps skinfold thickness all change little with age over certain parts of the age range. 15% of the boys and 22% of the girls had weights less than 75% of standard weight for age. The ability of age-independent indices to identify these low-weight individuals was investigated in terms of their sensitivity and specificity. Weight/height discriminated best, correctly classifying 85% of the low weight boys and 78% of the normal weight boys in the under-five age group. Weight/height and mid arm circumference were also useful, but triceps skinfold thickness and mid arm fat area did not discriminate usefully. All tests performed better in the under-five age group than in the older age bands.
