Purpose: To analyze the effects of customized home visiting health services on the health and health behaviors of clients with hypertension (n=107) and diabetes mellitus (DM: n=67). Methods: A one group pre and post-test research design was used. The subjects were registered in a customized 8-week, interventional, home visiting health services available in Daegu. Data was collected from November 17, 2008 to January 23, 2009. Analyses involved descriptive statistics, $x^2$ test and paired t-test. Result: Hypertension control rate was improved 25.2% and DM control rate was improved 3.0%. There were significantly beneficial hypertension-related differences in BP, health belief, health knowledge and health behaviors including performance of 10 min of moderate exercise, diet, BP monitoring and medication. Significantly beneficial DM-related changes included glucose, health belief, health knowledge and health behaviors including performance of 10 min of moderate exercise and glucose monitoring. But there were no significant hypertension-related differences in health belief (barrier) and health behavior including drinking and exercise length/frequency. Also, no significant DM-related differences were evident in health belief (barrier) and health behaviors including drinking, smoking, exercise length/frequency, diet and medication. Conclusion: Customized home visiting health service can provide effective, but not complete. Whether these benefits are maintained in the longer term is unknown.
