Self-reported versus measured weight and height in an older adult meal program population.

BACKGROUND: Self-reported weight and height are used to compute ponderal indices in studies where it is impractical to obtain objectively measured data. Little is known about the associations between self-reported and measured weight and height in older adults. METHODS: Participants in congregate and home-delivered meal programs in a rural Wisconsin county recorded their height and weight on a questionnaire as part of a study on nutritional risk and quality of life. Objective measurements of height and weight were made on the same day. Data for 131 subjects, ranging in age from 62-92 years, were analyzed to evaluate associations between self-reported and measured weights and heights. RESULTS: Correlation coefficients between self-reported and measured values suggested that self-reported weight was somewhat more valid than self-reported height in this population. However, self-reported weight was misreported by 10 pounds or more in 20% of the sample. CONCLUSIONS: More data are needed to evaluate the utility of self-reported data for weight and height in groups of older people. Judging from this study, self-reported height and weight data, if used at all for older adults, should only be used as a continuous variable rather than for classifying subjects into relative weight categories.

Factors associated with not receiving adequate prenatal care in an urban black population: program planning implications.

REcords of 36,608 Black single live births and 762 infant deaths in Washington, D.C., from 1980 to 1985 were analyzed. Bivariate and multivariate contingency table analysis were carried out to identify the groups at high risk for not obtaining adequate prenatal care. Results show that the groups of mothers which are less likely to receive adequate care also have a high risk of delivering low birthweight infants even when they receive adequate care. The paper focuses on women with high gravidity and short birth intervals for in-depth analysis of programming needs.

Programmed population control by cell-cell communication and regulated killing.

De novo engineering of gene circuits inside cells is extremely difficult, and efforts to realize predictable and robust performance must deal with noise in gene expression and variation in phenotypes between cells. Here we demonstrate that by coupling gene expression to cell survival and death using cell-cell communication, we can programme the dynamics of a population despite variability in the behaviour of individual cells. Specifically, we have built and characterized a 'population control' circuit that autonomously regulates the density of an Escherichia coli population. The cell density is broadcasted and detected by elements from a bacterial quorum-sensing system, which in turn regulate the death rate. As predicted by a simple mathematical model, the circuit can set a stable steady state in terms of cell density and gene expression that is easily tunable by varying the stability of the cell-cell communication signal. This circuit incorporates a mechanism for programmed death in response to changes in the environment, and allows us to probe the design principles of its more complex natural counterparts.

Teaching nurses to focus on the health needs of populations: a Master's Degree Program in Population Health Nursing.

Responding to the mandate to prepare nurses for practice in population-based healthcare, the faculty at Cleveland State University (CSU) developed a unique Master of Science in Nursing program to prepare Population Health Nurse Experts. The program prepares nurses to examine the health status of populations and to design, implement, and evaluate nursing interventions accounting for the varied factors impacting on the health of a defined group. The speciality of population health nursing is practiced by nurses who can use population sciences (epidemiology, demography, population projections, and population behavioral theories) along with post-baccalaureate nursing competencies to work with defined populations across care environments. The authors discuss a curriculum that prepares nurses for this emerging speciality.
