    Mseleni joint disease : a study of the clinical and radiological aspects and possible modes of inheritance
    (1983) Lockitch, Gillian; Fellingham, Stephen Arthur
    Mseleni Joint Disease is a disabling polyarticular disorder occurring with a high prevalence in the Mseleni area of Northern Zululand. During the past three years the series of epidemiological, genealogical and clinico-radiological studies carried out in the Mseleni Joint Disease Project have resulted in: 1. the localisation of a high prevalence area and a neighbouring control or low prevalence area; 2. the identification of individuals affected by the disease and of families consisting of many such individuals; 3. the definition of the clinical and radiological aspects of the disease. The description of these studies forms the subject of this thesis.

    A multivariate statistical approach to the assessment of nutrition status
    (1972) Fellingham, Stephen Arthur; Troskie, Casper G
    Attention is drawn to the confusion which surrounds the concept of nutrition status and the problem of selecting an optimum subset of variables by which nutrition status can best be assessed is defined. Using a multidisciplinary data set of some 60 variables observed on 1898 school children from four racial groups, the study aims to identify statistically, both those variables which are unrelated to nutrition status and also those which, although related, are so highly correlated that the measurement of all would be an unnecessary extravagance. It is found that, while the somatometric variables provide a reasonably good (but non-specific) estimate of nutrition status, the disciplines form meaningful groups and the variables of the various disciplines tend to supplement rather than replicate each other. Certain variables from most of the disciplines are, therefore, necessary for an optimum and specific estimate of nutrition status. Both the potential and the shortcomings of a number of statistical techniques are demonstrated.
