The evaluation of the Henry J. Kaiser Family Foundation's Community Health Promotion Grant Program: design

The Kaiser Family Foundation's Community Health Promotion Grant Program (CHPGP) provides funding and technical assistance in support of community-based efforts to prevent major health problems. The first phase of the program was implemented in 11 communities in the western United States. This paper describes the evaluation design of the CHPGP in the West, the methods of data collection, and the baseline comparability of intervention and control communities. Major features of the evaluation design include: (1) the randomization of qualified communities making application into funded and unfunded comparison groups; (2) a second set of matched control communities for some intervention sites; (3) data gathering through repeated surveys of community residents (probability samples of adults and adolescents) and institutions (health-related organizations and randomly sampled grocery stores and restaurants); and (4) the use of secondary data to monitor health events. Selected baseline data show that intervention and control communities differ in racial/ethnic composition, but relevant health behaviors and ratings of community activation for health promotion appear comparable.     

Integrating diet therapy and dietary counseling: an alternative education technique

The purpose of this study was to examine the effects of a change in education methods on learning among students enrolled in a coordinated undergraduate program (CUP). An experimental process applying the principles of diet therapy and counseling in a situation involving volunteer clients was initiated, and the effects were measured. A pretest-post-test design was used for this investigation. Two psychometric instruments, the Myers-Briggs Type Indicator and the Affective Sensitivity Scale, were used to measure changes in attitudes, values, and aptitude. The curriculum of the treatment group (19 juniors in the CUP) was reorganized so that diet therapy and dietary counseling would be taught during the same semester. The laboratory sessions were combined the last 6 weeks of the semester to provide an opportunity for students to counsel clients recruited from the university campus. The comparison group (11 seniors in the CUP) had enrolled in diet therapy the first semester of the junior year and dietetic counseling the second semester; those students were tested during their senior year. The research indicated that the students in the treatment group learned effectively. They significantly increased their awareness, listening, and understanding during the treatment period. The post-test of the treatment group indicated that they had increased perception and more acute affective sensitivity in comparison with the control group.     

Restrained drinking: risk factor for problems with alcohol?

A seven-item Drinking Restraint Scale (DRS) has been developed which indicates that a style of alcohol consumption, equivalent in a number of ways to the style of food consumption termed eating restraint, may exist. Several hypothesized relationships between DRS scores and other drinking-related measures were confirmed. A restrained drinking style was associated with: more extreme patterns of alcohol consumption; a higher proportion of drinking occasions that result in intoxication; more external styles of alcohol consumption control; and more alcohol-related negative consequences. The latter three relationships were found even when heavy drinkers were excluded from the analysis, which suggests that these relationships are not dependent on a heavy drinking pattern. These findings encourage continued investigation of drinking restraint as a risk factor for developing problems with alcohol.     

Congenital hip dislocation: the importance of early detection and comprehensive treatment.

Hip dislocation is the musculoskeletal condition most commonly missed during neonatal examinations. Failure to diagnose the condition can lead to long-term disability and is a common target in pediatric legal suits concerning damage to the musculoskeletal system. Early neonatal assessment for hip dislocation includes an examination using the Barlow and Ortolani tests. Later examinations include assessment of gluteal folds, knee height and the degree of hip abduction. The preferred treatment is use of the Pavlik harness, an outpatient treatment regime that provides effective reduction in 90 percent of the cases. The harness uses flexion and free abduction to direct the femoral head into the acetabulum; it uses time, gravity and motion to position the hip in a reduced position. The harness requires three to six months of continuous wear for the hip to become radiographically stable. Health care providers are instrumental in diagnosing congenital hip dislocation and teaching families how to promote the infant's physical and psychosocial well-being. If this condition is not detected until after the infant is 6 weeks old, or the harness is ineffective after three weeks, skin traction, closed reduction and spica-cast application may be needed. Open reduction and recasting are also options. In rare cases, total hip replacement is necessary in later life.     

Rural-urban differences in access to Iowa child health services.

Indicators of access, utilization, and quality of available child health services as well as health status were obtained through a telephone survey of Iowa households with children under age six. These indicators were compared for rural-urban subsamples within an AFDC sample drawn from Iowa Department of Human Service files (N = 637), and within poverty (N = 129) and nonpoverty groups (N = 631) drawn from the population of all households in the state with children under age six. About 55 percent of all households studied were rural. Rural households were generally larger than urban households, more likely to be intact maritally, white, and earning a living from farming. The findings support the hypothesis that place of residence has an impact on access, utilization, and quality of child health services over and above family income, although not always to the disadvantage of rural children. Typical problems for rural children, irrespective of income, were access to pediatric care, greater travel time to providers, and discontinuity of well care and sick care. Rural children in all income groups had lower seat belt use than urban children; they were also less likely to have well visits and their providers showed less attentiveness to behavioral and developmental issues at these visits. Rural residency exacerbated problems in access to care for low income children, who were less likely to be eligible for AFDC/Medicaid than their urban counterparts. Medicaid coverage, however, did not eliminate rural-urban differences in receiving desired medical care.     

Hemorrhagic intracranial malignant neoplasms: spin-echo MR imaging

Twelve patients with 15 separate, spontaneously hemorrhagic, intracranial malignant lesions (seven primary gliomas, eight metastatic lesions) were examined with spin-echo magnetic resonance imaging at 1.5 T, and with computed tomography. The signal intensity patterns of these lesions, as seen on both short repetition time (TR)/short echo time (TE) and long-TR/long-TE spin-echo pulse sequences, were compared with the previously described appearance at 1.5 T of non-neoplastic intracerebral hematomas. The images of hemorrhagic intracranial malignancies showed notable signal heterogeneity, often with identifiable nonhemorrhagic tissue corresponding to tumor; diminished, irregular, or absent hemosiderin deposition; delayed hematoma evolution; and pronounced or persistent edema, compared with non-neoplastic hematomas. The demonstration of these characteristics in the appropriate clinical setting may suggest malignancy as the cause of an intracranial hematoma.     

Complete and partial ureteral obstruction: evaluation of renal effects with P-31 MR spectroscopy and Tc-DMSA scintigraphy

Phosphorus-31 magnetic resonance (MR) spectroscopy was used to study the effects of partial and complete ureteral obstruction on the porcine kidney; results were compared with renal tubular function as determined with technetium-99m dimercaptosuccinic acid (DMSA) scintigraphy. Twenty-seven pigs were used: nine as sham-operated controls, six with partial ureteral obstruction, and 12 with complete ureteral obstruction. P-31 MR spectra and Tc-DMSA scintiscans were obtained weekly over 3 weeks. Partial obstruction caused no significant change in P-31 MR spectra, whereas Tc-DMSA scintiscans showed a 74% decrease in tubular function by the end of 3 weeks. Complete obstruction caused a 43% reduction in the mean adenosine triphosphate (ATP) to inorganic phosphate (Pi) ratio, which paralleled the 96% decrease in Tc-DMSA uptake over 3 weeks. The difference in ATP/Pi ratios between control and completely obstructed kidneys was significant (P less than .01) at 2 and 3 weeks after ligation. These results indicate that radionuclide Tc-99m DMSA uptake is very sensitive to the pathophysiologic changes in renal tubular function, while the organ average cellular bioenergetic state (ATP/Pi) is not as strongly affected.
