Abstract

Purpose: The short-term effectiveness of the nutrition-centred Complete Health Improvement Program (CHIP) lifestyle intervention for improving selected chronic disease risk factors was examined in the Canadian setting.
Methods: A total of 1003 people (aged 56.3 ± 12.1 years, 68% female) were self-selected to participate in one of 27 CHIP interventions hosted in community settings by Seventh-day Adventist churches throughout Canada, between 2005 and 2011. The program centred on the promotion of a whole-food, plant-based eating pattern, and daily physical activity was also encouraged. Biometric measures, including body mass index (BMI), blood pressure (BP), blood lipid profile, and fasting blood sugar (FBS), were determined at program entry and 30 days into the intervention.
Results: Over 30 days, significant overall reductions (P<0.001) were recorded in the participants’ BMI (-3.1%), systolic BP (-7.3%), diastolic BP (-4.3%), total cholesterol ([TC] -11.3%), low-density lipoprotein cholesterol ([LDL-C] -12.9%), triglycerides ([TG] -8.2%), and FBS (-7.0%). Participants with the highest classifications of TC, LDL-C, TG, and FBS at program entry experienced approximately 20% reductions in these measures in 30 days.
Conclusions: The CHIP intervention, which centres on a whole-food, plant-based eating pattern, can lead to rapid and meaningful reductions in chronic disease risk factors in the Canadian context.

Résumé

Objectif: L’efficacité à court terme de l’intervention sur le style de vie axée sur la nutrition Complete Health Improvement Program [Programme global d’amélioration de la santé] (CHIP) à améliorer certains facteurs de risque de maladies chroniques a été examinée en contexte canadien.
Méthodes: Au total, 1003 personnes (âgées de 56,3 ± 12,1 ans, 68% de femmes) se sont portées volontaires entre 2005 et 2011 pour participer à l’une de 27 interventions CHIP chapeautées dans la communauté par des églises adventistes du septième jour de partout au Canada. Le programme était axé sur la promotion d’habitudes alimentaires à base d’aliments entiers de source végétale, et l’activité physique quotidienne était également encouragée. Des mesures biométriques, dont l’indice de masse corporelle (IMC), la tension artérielle (TA), le profil lipidique sanguin et la glycémie à jeun (GJ) ont été prises au commencement du programme puis 30 jours après le début de l’intervention.
Résultats: Après 30 jours, des réductions globales significatives (p < 0,001) ont été notées chez les participants en ce qui a trait à l’IMC (-3,1%), à la TA systolique (-7,3%), à la TA diastolique (-4,3%), au cholestérol total ([CT] -11,3%), au cholestérol à lipoprotéines de faible densité ([C-LDL] -12,9%), aux triglycérides ([TG] -8,2%) et à la GJ (-7,0%). Les participants présentant les résultats les plus élevés pour le CT, le C-LDL, les TG et la GJ au début du programme ont connu une réduction d’environ 20% de ces mesures en 30 jours.
Conclusions: L’intervention CHIP, qui est axée sur des habitudes alimentaires à base d’aliments entiers de source végétale, peut rapidement mener à une réduction significative des facteurs de risque de maladies chroniques en contexte canadien.
