ABSTRACT
OBJECTIVE: To determine whether a community based coronary heart disease health promotion project, undertaken over four years, was associated with changes in the prevalence in adults of lifestyle risk factors known to affect the development of coronary heart disease, and to estimate whether such an approach was cost effective. DESIGN: Prospective, comparative study of the effects of a health promotion intervention on coronary heart disease lifestyle risk factors, assessed by postal questionnaire sent to a randomly chosen sample, both at baseline and after four years. SUBJECTS: Intervention and control populations of adults aged 18-64 in Rotherham, both from areas with a high incidence of coronary heart disease and similar socioeconomic composition. MAIN OUTCOME MEASURES: Changes in prevalence of lifestyle risk factors between the control and intervention communities from 1991 to 1995. The effect of the intervention on certain lifestyle behaviours was evaluated using multiple logistic regression to model the proportion with a particular behaviour in the study communities as a function of age (18-40 or 41-64 years), sex, the year of observation (1991 or 1995), and area (intervention of control). RESULTS: 6.9% fewer people smoked and 8.7% more drank low fat milk in the intervention area, but no other statistically significant changes between the areas were detected. The estimated cost per life year gained was pounds 31. CONCLUSIONS: It is possible to have a cost effective impact on coronary heart disease lifestyle risk factors in a population of adults over four years using only modest resources.

A community health promotion project called Action Heart was undertaken in two electoral wards in Rotherham to try to change lifestyles of people. Schools were included within the project. Coronary heart disease lifestyle risk factors were measured at baseline and after a three year period in the intervention area and a similar control area. Lifestyle factors in schoolchildren were measured separately from adults using a different instrument. The post intervention survey of adults and economic evaluation demonstrated that Action Heart had achieved cost-effective estimated health gains. In the schoolchildren however, a mixture of positive and negative risk factor changes in both areas was demonstrated. Significant changes in lifestyle risk factors in schoolchildren were not elicited using this approach. The possible reasons for the lack of impact on lifestyle risk factors in schoolchildren are examined and the implications for further work explored.

The triolein breath test (TBT) is a simple, noninvasive technique for the evaluation of steatorrhea. However, because it depends on intermediary hepatic processes, and because both liver damage and pancreatic dysfunction often co-exist in the alcoholic, the overall usefulness of the test in patients with liver injury was reassessed. We found that even in the absence of steatorrhea, a majority of patients with advanced liver injury (alcoholic hepatitis, cirrhosis, or both) had abnormal TBT results that failed to correct with pancreatic extract. In contrast, patients with less severe lesions (steatosis) had results that were not significantly different from those in normal controls. Inasmuch as the abnormal TBT results in patients with advanced alcohol-induced lesions did not correct with pancreatic extract, the test may not accurately differentiate pancreatic from nonpancreatic steatorrhea in some alcoholics.
