Impact of short-duration lifestyle intervention in collaboration with general practitioners in patients with the metabolic syndrome.

AIM: As the constantly progressing metabolic syndrome is accompanied by an increased risk of type 2 diabetes and cardiovascular complications, it is essential to take appropriate, non-pharmacological, cost-effective measures immediately after the diagnosis has been made. The purpose of our prospective, non-controlled, 6-month study was to determine the impact of lifestyle interventions involving patients' behaviour in collaboration with their general practitioners (GPs).

METHODS: We recruited 95 patients (46 men and 49 women, aged 45 to 60 years) who presented with the metabolic syndrome. Each patient received a copy of the national French recommendations (PNNS) leaflet, containing guidelines aimed to balance dietary intake and increase daily physical activity. Socioeconomic status was estimated using the EPICES score. Following a less than 1 hour face-to-face interventional session with each patient to present the lifestyle-modification goals, we contacted each patient's GP by phone to advise on measures to reinforce these lifestyle modifications.

RESULTS: The percentage of patients presenting with the metabolic syndrome decreased by 52.4% after 6 months. Hypertension, triglycerides and waist circumference decreased by 30.5, 29.3 and 22.0%, respectively, in the study patients. Rates of compliance to PNNS goals at the last follow-up versus baseline were: for drinks, 63.0% versus 22.2%; for sweet products, 91.4% versus 49.4%; for fat, 91.4% versus 80.3%; and for increased exercise, 26.9% versus 6.4%.

CONCLUSION: Short-term, single lifestyle modifications targeting the metabolic syndrome in collaboration with GPs was effective in decreasing most of the parameters of the syndrome. However, no factors predictive of success were identified.
