Intensive Lifestyle Intervention for Type 2 Diabetics: The KP TLC Pilot (KPTLCP)

Intensive Lifestyle Intervention for Type 2 Diabetics: The Kaiser Permanente TLC Pilot

The purpose of this study is to determine if a healthy lifestyle intervention can significantly improve blood sugar control in type 2 diabetics over a course of 3 months.

Study Overview

• Status: Withdrawn
• Conditions: Type 2 Diabetes
• Intervention / Treatment: Behavioral: Coronary Health Improvement Project Program

Detailed Description

Peer reviewed research studies have proven the benefits of lifestyle interventions including the reversal of coronary artery disease and of diabetes. Experts agree that such a lifestyle must include a diet rich in whole, grown foods while low in saturated fat and cholesterol; regular physical activity; and healthy ways to cope with stress.

There are several challenges with implementing such lifestyle interventions such as educating the general public and health care providers to the components of this lifestyle and in getting people to adopt these healthy lifestyle changes.

While retreat-style, intensive lifestyle programs have shown that these obstacles can be overcome, they require monetary and time investments generally not feasible for the general public.

A community-based, lifestyle program such as 'The Coronary Health Improvement Project' program offers similar potential benefits at a more reasonable cost. It does so through an intensive education (32 hours total) taught over 4 weeks, followed by an 8-week consolidation period which include live or DVD based group sessions, discussions led by a program facilitator, and medical monitoring.

Kaiser Permanente, the leading Health maintenance organization in the nation, places special focus and significant resources into preventive medicine and health promotion, providing services to thousands of plan members but none with the level of intensity of 'The Coronary Health Improvement Project'.

This study aims to determine if 'The Coronary Health Improvement Project' program can significantly improve blood sugar control in kaiser plan members with uncontrolled diabetes.

Behavioral: Coronary Health Improvement Project Program; The Coronary Health Improvement Project' (CHIP; an intensive, community-based, lifestyle change program including a low saturated fat diet rich in whole, grown foods) has been shown to improve the health of diabetics through an intensive education taught over a 12 week period, but has not been studied in terms of its effect on HBAIC. Kaiser Permanente places significant resources into preventive medicine but does not have programs with the level of intensity of CHIP. This study aims to determine if Kaiser members with uncontrolled type 2 diabetes can achieve a significant improvement in their HBAIC after 12 weeks of participation in the CHIP program.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
HBAIC before and after intervention	Baseline HbA1C will be measured within two weeks of the start of the intervention. Follow-up HbA1C will be measured at 12 weeks after the start of the intervention, as HbA1C is a measure of glycemic control over approximately 12 weeks.	3 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Average weekly blood sugar	Baseline blood glucose readings will be checked one week prior to the start of the intervention, as well as weekly during the study for medication adjustment by a specialized Kaiser Permanente physician (weekly monitoring of blood glucose levels based on checks performed 3 times/day, for at least 3 consecutive days during the week, and then averaged). Follow-up blood glucose levels will be self-measured by patient glucometer, 3 times/ day, for at least 3 consecutive days. The average of these readings will be computed, as the "average weekly blood sugar"	3 months
Lipids	Baseline fasting lipid panel will be ascertained within two weeks prior to the start of the intervention. Follow-up fasting lipids will be measured at 4 weeks and at 12 weeks after the start of the intervention.	3 months
Weight	Baseline height, weight, waist circumference, hip circumference, and systolic and diastolic blood pressure will be measured within one week of the start of the intervention. Follow-up measures will be ascertained at 4, 8, and 12 weeks after the start of the intervention.	3 months
waist circumference	Baseline height, weight, waist circumference, hip circumference, and systolic and diastolic blood pressure will be measured within one week of the start of the intervention. Follow-up measures will be ascertained at 4, 8, and 12 weeks after the start of the intervention.	3 months
Blood pressure	Baseline height, weight, waist circumference, hip circumference, and systolic and diastolic blood pressure will be measured within one week of the start of the intervention. Follow-up measures will be ascertained at 4, 8, and 12 weeks after the start of the intervention.	3 months
