Nutrition assessment: a management tool for providing quality care.

When planning nutrition intervention programs in a health care facility or the community, an analysis of the service population is necessary to determine the levels of care than can be provided. The use of screening and monitoring techniques will maximize the resources that are available and increase the amount of care that can be given. By using baseline nutrition assessment data, health outcomes can be measured over time and cost-effectiveness of the program can be evaluated. Examples of studies that measure effectiveness of nutrition services and programs are reviewed. Specific steps are suggested to simplify the documentation of the process and outcomes of nutrition intervention.

Colorimetric measurement of glycosylated protein in whole blood, red blood cells, plasma and dried blood.

A colorimetric method for the measurement of whole-blood glycosylation (WBG), glycosylated haemoglobin in red blood cells (GHb), glycosylated plasma protein (GPP) and dried-blood glycosylation (DBG) is described which is rapid, inexpensive and precise. GHb correlated well with HbA1 measured by cation-exchange chromatography and was also correlated with WBG, DBG and GPP. DBG, which showed good correlation with GHb, could be measured on several drops of blood dried on filter paper treated with glucose oxidase. Filter papers are posted to the laboratory prior to clinic visits, and by having the DBG result available more rational diabetic management is possible. For DBG, the intra- and inter-assay coefficient of variation at three levels is less than 6%. Reference values in non-diabetic children have been calculated and are compared with values obtained in 'good' clinical diabetic control and in 'fair' control. The filter-paper assay DBG method has a high degree of patient acceptance.

The Anti-Coronary Club: 1957 to 1972.

The Diet and Coronary Heart Disease Study Project, known as the Anti-Coronary Club, was established by the New York City Department of Health, Bureau of Nutrition in June 1957. The major goals were: 1) to develop an acceptable experimental diet capable of reducing serum cholesterol in ambulatory middle-aged men; and 2) to test the hypothesis that a reduction in serum cholesterol is associated with a modified diet and a reduced incidence of coronary heart disease development. The Prudent Diet was developed to provide a way of eating consistent with the American dietary pattern, avoiding an excess of empty calories, saturated fat, and food cholesterol. It provides a favorable balance of nutrients, limits total fat content and makes possible a more desirable ratio of PUFA to saturated fats. Based on the data, it seems reasonable to attribute the lower coronary heart disease incidence rates in the active experimental group of both age categories studied (40 to 49 and 50 to 59) directly to the reduction in serum cholesterol levels, with weight reduction as a beneficial accomplishment. Dietary intervention with the Prudent Diet was instrumental in achieving the lower coronary heart disease incidence rates that demonstrated the efficacy of the Prudent Diet as a sensible diet.

Factors predictive of response to growth hormone therapy in Turner's syndrome.

In Turner's syndrome there is marked heterogeneity of growth response to growth hormone (GH) therapy. The study aim was to identify pretreatment factors that influence response to GH therapy. The 70 subjects recruited were prepubertal, had not received sex steroids and had received 28 units/m2/week of GH for > or = 1 year. Pretreatment variables associated with the greatest improvement in height SDS (r2 = 0.58) were weight for length index (p = 0.0001), target height (p = 0.004), bone age delay (p = 0.008) and age (p = 0.04). In conclusion, during two years of GH therapy the best growth response occurred in girls who were younger, heavier, had a delayed bone age and tall parents. Height SDS as a continuous variable is the most effective measure of growth when considering pretreatment factors that may influence response to GH therapy.
