Abstract

AIM:

To examine the effectiveness within the Australasian context of the Complete Health Improvement Program (CHIP) lifestyle intervention, which has been shown to produce meaningful reductions in selected chronic disease risk factors in the United States.

METHODS:

Changes in body weight, blood pressure, blood lipid profile and fasting plasma glucose were assessed in 836 self-selected participants (age=55.9 plus or minus 12.7 yrs, 35% male/65% female) from 18 sites throughout New Zealand (N=731) and Australia (N=105).

RESULTS:

In the 30 days of the program, significant overall reductions (p<0.001) were recorded in the participants' body mass (-3.8%; 87.1 plus or minus 22.4 versus 83.9 plus or minus 21.5 kg), systolic blood pressure (-5.6%; 135 plus or minus 19 versus 127 plus or minus 17 mmHg), diastolic blood pressure (-4.6%; 80 plus or minus 12 versus 76 plus or minus 12 mmHg), total cholesterol (-14.7%; 5.17 plus or minus 1.08 versus 4.41 plus or minus 0.96 mmol/L), low-density lipoprotein cholesterol (-17.9%; 3.17 plus or minus 0.95 versus 2.60 plus or minus 0.83 mmol/L), triglycerides (-12.5%; 1.51 plus or minus 0.98 versus 1.32 plus or minus 0.71 mmol/L) and fasting plasma glucose (-5.6%; 5.55 plus or minus 1.49 versus 5.24 plus or minus 1.11 mmol/L). Participants at program entry with the highest classifications of total cholesterol, low-density lipoprotein, triglycerides and fasting plasma glucose experienced over 20% reductions in these measures in 30 days.

CONCLUSIONS:

Significant reductions in selected chronic disease risk factors were observed in 30 days using the CHIP intervention and the improvements were comparable to that observed in cohorts from the United States. The results of this feasibility study indicate that lifestyle interventions like CHIP may be useful for combating the burgeoning epidemic of chronic disease and further research is warranted.
