Hoe lang duurt het voordat u veranderingen in levensgewoontes merkt?*

Als u echt uw voedingsgewoontes verandert en iedere dag gaat bewegen duurt het zes weken om de kans op chronische ziektes duidelijk te verminderen, volgens een studie van de Brigham Young Universiteit. Men volgenden 337 personen in de leeftijd van 43-81 jaar gedurende zes weken en men constateerde duidelijke vermindering van het lichaamsvet, cholesterol waarden (gemiddeld 12% minder). Het aantal personen met hoge bloeddruk nam af van 18,% tot 7,%. De personen kregen een voedingsdieet rijk aan fruit, groenten, bonen, peulen, soja en granen verder moest men iedere dag 30 minuten redelijk intensief bewegen. Zij die vooraf een cursus gevolgd hadden over de voordelen van veranderde levensgewoontes hadden duidelijk nog betere resultaten.

Abstract

Background

This study assessed the clinical impact of lifestyle change education on chronic disease risk factors within a community.

Design

Randomized clinical trial.

Setting/participants

Participants included 337 volunteers age 43 to 81 years from the Rockford, IL, metropolitan area.

Intervention

The intervention group attended a 40-hour educational course delivered over a 4-week period. Participants learned the importance of making healthful lifestyle choices and how to make improvements in nutrition and physical activity.

Main outcome measures

Changes in health knowledge, nutrition, and physical activity behavior, and several chronic disease risk factors were assessed at baseline and 6 weeks.

Results

Beneficial mean changes in scores tended to be significant for the intervention group but not for the control group. Variables with improved scores included health knowledge, percent body fat, total steps per week, and most nutrition variables. Clinical improvements were seen in resting heart rate, total cholesterol, low-density lipoprotein cholesterol, and systolic and diastolic blood pressure. The control group experienced comparatively small but significant improvements in health knowledge, systolic and diastolic blood pressure, glucose, and in some nutrition variables. For almost all variables, the intervention group showed significantly greater improvements.

Conclusions

This lifestyle modification program is an efficacious nutrition and physical activity intervention in the short term and has the potential to dramatically reduce the risks associated with common chronic diseases in the long term.
