It was expanded into a statewide program and integrated into PHC, linked to periodic immunization initiatives (IVACG, 1992). The book also analyzes the composition of important foods and feed ingredients and offers guidelines on feed processing and diet formulation. After 18 months, project evaluation documented improved KAP, greater consumption of DGL Vs and some fruits (papaya), and a reduction of xerophthalmia, all indicators of at least short-term success. Annu Rev Nutr. 9:180–185. 91–116. : L517–L527. Although the national survey of 1977–1978 (23 of 27 provinces) has not been repeated, surveys in 15 individual provinces conducted in 1992 suggested that xerophthalmia was no longer of public health significance. Some situations may require only the availability of simple food grinders or sieves. 125:1211–1221. New York. Would you like email updates of new search results?

From birth onward, an infant's vitamin A status on the continuum may advance by small increments, be maintained, or deteriorate, depending on the balance between dietary intake relative to growth and development needs and to disease patterns that effect vitamin A economy. It is in these areas that local NGOs can make major contributions. Significant improvement in serum levels of retinol followed the addition of vegetables that contained beta-carotene (750 RE/day was the highest level fed). through nutrition education may relate to the lack of a systematic analysis of the local situation.

Recent reports from closely monitored, random, controlled vitamin A supplementation field trials in deficient children clearly demonstrate a decreased severity of subsequent diarrheal morbidity (Barreto et al., 1994; Bhandari et al., 1994). Data from this surveillance system, together with some small surveys and clinical trials, called attention to the serious public health problem that affects certain areas and was seen nationally in "at-risk" groups (Kavishe, 1992). Report of a WHO Expert Committee, WHO Technical Report Series 854. Results. Nutr. Also, multiple DGLVs were promoted, rather than a single product.

Am. The examples of field experience reviewed above represent strong arguments for formulating an overall national control strategy in which interventions overlap, each receiving the degree of emphasis appropriate for the community context and the severity of the VAD problem and a comparable share of the resources available for VAD control. 1992.

Ending Hidden Hunger: A Policy Conference on Micronutrient Malnutrition. Whenever food consumed by the target population can be fortified at reasonable cost, fortification can provide the same vitamin A-related benefits as changes in diet, and it is likely to be easier and occur faster.

A subanalysis of data from the women in each of the three groups showed that all responded; the enriched-wafer group responded significantly more than the other two groups, whose responses were not significantly different (de Pee et al., 1995). If national strategies are planned to concurrently begin to phase in more sustainable food-based approaches, the high coverage achieved through special event days and other specially created delivery systems should not be required beyond 2 to 5 years. The link in humans between clinically evident symptoms and signs and a faulty diet was suggested in about 1860 and subsequently confirmed in many societies (Guggenheim, 1981; Wolf, 1996). a In addition, a serum level of vitamin A (retinol) has been used with the clinical classification to provide supportive evidence of an important problem. 1995. organizations (NGOs) (women's groups) complement the mass media strategies to attain the interpersonal contact through home visits that is needed to reinforce desired modifications in behavior and to contact hard-to-reach and high-risk populations (such as poor urban residents and those not attending local health posts). These general criteria, as well as additional factors found to be specific to the vitamin A context, were the framework used to judge the vitamin A control programs reviewed for this paper.
