  • Nutritional Status Assessment Full nutritional status assessment is reserved for seriously ill patients and those at very high nutritional risk when the cause of malnutrition is still uncertain after initial clinical evaluation and dietary assessment. It involves multiple dimensions, including documentation of dietary intake, anthropometric measurements, biochemical measurements of blood and urine, clinical examination, health history, and functional status. For further discussion of nutritional assessment, see Chap. 72.

  • Assessment of Circulating (Visceral) Proteins The serum proteins most used to assess nutritional status include albumin, total iron-binding capacity (or transferrin), thyroxine-binding prealbumin (or transthyretin), and retinol-binding protein. Because they have differing synthesis rates and half-lives—the half-life of serum albumin is about 21 days whereas those of prealbumin and retinol-binding protein are about 2 days and 12 h, respectively—some of these proteins reflect changes in nutritional status more quickly than others.

  • T he science of human nutrition and its applications to health promotion continue to gain momentum. In the relatively short time since the release of the first edition of this Encyclopedia, a few landmark discoveries have had a dramatic multiplying effect over nutrition science: the mapping of the human genome, the links between molecular bioenergetics and lifespan, the influence of nutrients on viral mutation, to name a few.

  • Acute Care Settings Acute care settings, anorexia, various diseases, test procedures, and medications can compromise dietary intake. Under such circumstances, the goal is to identify and avoid inadequate intake and ensure appropriate alimentation. Dietary assessment focuses on what patients are currently eating, whether they are able and willing to eat, and whether they experience any problems with eating. Dietary intake assessment is based on information from observed intakes; medical record; history; clinical examination; and anthropometric, biochemical, and functional status.

  • The poor nutritional status of women in developing countries has been associated with maternal mortality. Maternal deaths do not result from malnutrition alone, however, but mainly from a lack of access to obstetric care and from previous conditions that may be aggravated by poor nutrition.

  • It has been recognized for many years that states of nutrient deficiency are associated with an impaired immune response and with increased susceptibility to infectious disease. In turn, infection can affect the status of several nutrients, thus setting up a vicious circle of under nutrition, compromised immune function and infection.

  • The sex distribution in SEC is reasonably close to that in the 1998 census and 2000 DHS. The 1999 Socioeconomic Survey is somewhat out of line with the other sources. Likewise, the age distribution of older persons in the SEC is quite similar to that in the other sources. The marital status distribution in the SES for men is also fairly similar to that found in the other three sources but not for women. The SEC sample has relatively fewer women who are currently married and relatively more who are widowed than indicated by the census and the...

  • A coffeepot that was connected to the Internet (before it was even called the Internet) and which provided information about its status (long before there was Twitter). In 1991, researchers at Cambridge University shared a single coffeepot among several floors. The researchers were frustrated by the fact that they would often climb several flights of stairs, only to find the coffeepot empty. They set up a videocamera that broadcast a still image to their desktops about three times per minute — enough to determine the level of coffee in the glass pot.

  • Acupuncture is growing in popularity world-wide. Since it started to be scientifically studied in the 1970’s, acupuncture is conquering position as an efficient and safe therapeutic method. The amount of cumulated scientific evidence is already enough to guarantee a highly detached status for acupuncture among other complementary therapies. In many countries, acupuncture is well integrated into the conventional health system. This scenario would seem to be very favorable and the value of acupuncture would thus seem well consolidated.

  • In community-dwelling elders, the relation between dietary quality, social support and living arrangements is controversial. Some studies have found positive relations,21,65,68,70,78-80 whereas others have found diet quality to be unaffected by a poor social network.81 It has been suggested that geographical isolation has an adverse effect on nutritional status among the elderly.

  • There is no doubt that the protection of women during pregnancy and lactation must be one of the major priorities of health systems and social policies. The effect of women’s nutritional status on pregnancy outcomes is particularly strong, and adequate maternal nutrition is closely related to the survival and well-being of babies and children. However, not all women are mothers, and their nutritional and health needs go far beyond motherhood and reproduction. Women of all ages in developing countries face elevated risks of nutritional deficiencies.

  • The Hypothalamushypophysis- gonadal (HPG) axis is subject to both positive feed-forward and negative feedback regulation at several levels. At the level of the hypothalamus, early recognition of the pulsatile nature of gonadotropin releasing hormone secretion led to the notion of a central ‘‘pulse generator”, the inherent oscillatory activity of which controls the secretory rhythm of GnRH neurons (Knobil, 1980).

  • In addition to this, health measures typically used in empirical studies may be affected by endogenous reporting behaviour. The outcome of a direct question to an individual’s health status may depend on the labour market status of the respondent. There may be economic motives or it may be the case that individual’s are inclined to give their answer conform to social norms. Reporting health as a major determinant for inactivity is socially more accepted, and eligibility conditions for some Social Security Benefits, notably Disability Insurance ...

  • Available information shows that the nutritional status of Mexican women differs widely within the country, according to geographical regions, urban and rural areas, and income groups. Nutritional deficiencies, anaemia and stunting, for example, are more common in poor women who live in the less-developed regions of the country, in rural and indigenous communities or in marginal urban areas. On the other hand, overweight and obesity currently affect women of all income groups, but rates are higher in the more economically advanced regions and big cities.

  • What have been the impacts of the GGDP-generated maize technologies? In the absence of reliable baseline data, it was not possible to calculate quantitative measures of project impact. Based on farmers’ qualitative judgments, however, it is clear that adoption of the GGDP-generated technologies has been associated with significant farm-level productivity gains (measured in terms of maize yields) and noticeable increases in the income earned from sales of maize. Impacts on the nutritional status of rural households, however, appear to have been less pronounced.
