Protein-energy malnutrition and the home environment : a study among children in Coast Province, Kenya
Abr. abstr.: This is an account of a study concerning the occurrence of childhood malnutrition in Kilifi District, Kenya. The socioeconomic characteristics of women with malnourished children who attended Kilifi Family Life Training Centre in the year 1984/1985 were analysed. Next, the possible influence of intra-household factors on the occurrence of childhood malnutrition was examined. A comparison of two groups of ten mother/child pairs, focusing on feeding and weaning patterns, hygiene, parental care and home stimulation, revealed important variations as regards child/caretaker relationships. In households where no malnutrition had occurred, children were fed more regularly and were provided with more types of stimulation. The question remains whether a malnourished child generates a lower level of stimulation on the caretaker's part, or whether lack of stimulation by the caretaker leads to an increased risk of malnutrition. However, the present findings indicate not only that a relationship between childhood malnutrition and home stimulation exists, but that it persists beyond the acute episode and subsequent rehabilitation. Consequently, it is recommended that emphasis during rehabilitation should not only be on nutritional requirements and general child care, but also on individual attention and stimulation given to the chil
Non-universal behavior for aperiodic interactions within a mean-field approximation
We study the spin-1/2 Ising model on a Bethe lattice in the mean-field limit,
with the interaction constants following two deterministic aperiodic sequences:
Fibonacci or period-doubling ones. New algorithms of sequence generation were
implemented, which were fundamental in obtaining long sequences and, therefore,
precise results. We calculate the exact critical temperature for both
sequences, as well as the critical exponent , and . For
the Fibonacci sequence, the exponents are classical, while for the
period-doubling one they depend on the ratio between the two exchange
constants. The usual relations between critical exponents are satisfied, within
error bars, for the period-doubling sequence. Therefore, we show that
mean-field-like procedures may lead to nonclassical critical exponents.Comment: 6 pages, 7 figures, to be published in Phys. Rev.
High temperature thermal conductivity of 2-leg spin-1/2 ladders
Based on numerical simulations, a study of the high temperature, finite
frequency, thermal conductivity of spin-1/2 ladders is
presented. The exact diagonalization and a novel Lanczos technique are
employed.The conductivity spectra, analyzed as a function of rung coupling,
point to a non-diverging limit but to an unconventional low frequency
behavior. The results are discussed with perspective recent experiments
indicating a significant magnetic contribution to the energy transport in
quasi-one dimensional compounds.Comment: 4 pages, 4 figure
Preliminary studies on some aspects of Kikuyu food habits
Description of a research project. The studies cover general aspects of Kikuyu food habits such as foods presently in use, the classification of foods and food preferences for children. The emphasises is on the methods employed in these studies which can also be used elsewhere to obtain information vital to the evaluation and planning of child nutrition programmes. A discussion on foods used by the Kikuyu in the rural areas is accompanied by a list of food names in the vernacular.ASC – Publicaties niet-programma gebonde

The impact of nutrition education at three health centres in Central Province, Kenya
This report contains an account of a study of the effects of nutrition education as given at three health centres in different ecological zones in Central Province, Kenya. Two groups of mothers in similar social and economic situations were selected for interviewing: frequent and infrequent visitors. They were compared on the following indicators: nutritional knowledge, maternal food preferences, food consumption of the children during the previous day and nutritional status of the children. Conclusion: nutrition education has little or no impact on the whole range of nutritional attitudes of mothers, their behaviour and the nutritional status of children.ASC – Publicaties niet-programma gebonde
The nutritional impact of the Pre-School Health Programme at three clinics in Central Province, Kenya
Contains an account of a study of the effects of the Pre-School Health Programme at three clinics in different ecological zones in Central Province, Kenya. Two groups of mothers were selected for interviewing: recent entrants and longtime participants. The study concentrates on the following aspects: nutritional knowledge; maternal food preferences; food consumption of the children during the previous day; and nutritional status of the children. Conclusion: the strenght of the programme lies in the food distribution rather than in the educational component.ASC – Publicaties niet-programma gebonde
