Comparative Study
Do nutrition programs make a difference? The case of Brazil.
Four Brazilian food and nutrition programs operating during some part of 1974-86 are evaluated for their effectiveness in curing or preventing infant and child malnutrition, including low birth weight when pregnant women were beneficiaries. Two programs distributed free food to identified clients: traditional commercial foods in one case and specially formulated supplements in the other. The other two programs subsidized four or more basic foodstuffs: one experiment quantitatively restricted a subsidy to identified families, and the other was unrestricted and open to all families patronizing certain shops. ⋯ Donation programs including medical and educational components proved more effective than pure subsidies, showing that while poverty may be the chief cause of malnutrition, the problem should be seen as poor health rather than simply low food consumption. Evaluation also shows that programs were inefficient in transferring benefits, and that clients were deterred from participating by the costs of obtaining the food and its poor quality and small volume. Longer participation improved results, but more frequent participation in a given interval did not necessarily do so.

ReviewThe epidemiology of acute respiratory infections in children and adults: a global perspective.
While a number of advances have been made in our understanding of the epidemiology of acute respiratory infections in the past two decades, a number of serious questions still require urgent answers. The associations of factors such as chronic disease in adults, direct smoking, passive smoking, crowding, and breast feeding to acute respiratory infections are now well documented. Appropriate changes in public health policy need not be predicated on results from still further studies. ⋯ Greater standardization of data collection methods in developed and developing countries also needs to be more seriously addressed. Given that some advances have been made in this area, the time may be right for development of acute symptom questionnaires, akin to the American Thoracic Society chronic respiratory questionnaire, for use in both developed and developing countries. Standardization of diaries, although somewhat more difficult, would also be extremely useful in many instances.

Comparative Study
Do the benefits of breastfeeding outweigh the risk of postnatal transmission of HIV via breastmilk?
Conflicting recommendations have been offered about whether HIV+ mothers should breastfeed. Since there is a strong precedent for US infant feeding practices to be imitated in developing countries, a model was constructed to estimate infant mortality if the CDC admonition for HIV+ mothers not to breastfeed were upheld in less developed settings. ⋯ The infant mortality associated with HIV infection acquired through breastfeeding is estimated to be lower than the mortality associated with the diseases of infancy that would result if breastmilk were withheld. The difference in these estimates is greater in areas with high baseline levels of infant mortality.

Global review on ORT (oral rehydration therapy) programme with special reference to Indian scene.
This communication is an attempt to review the status and implementation of the Oral Rehydration Therapy in the programme for Control for Diarrhoeal Diseases. The Global and the Indian situations are separately discussed, with more emphasis on the latter. Use of Home Available Fluids (HAF), Salt Sugar Solution (SSS). Commercial packets of ORS and the Government supplied packets of ORS are also assessed.
