Preconception lifestyle intervention reduces long term energy intake in women with obesity and infertility: a randomised controlled trial.

ABSTRACT: BACKGROUND:The preconceptional period may be an optimal window of opportunity to improve lifestyle. We previously showed that a 6?month preconception lifestyle intervention among women with obesity and infertility was successful in decreasing the intake of high caloric snacks and beverages, increasing physical activity and in reducing weight in the short term. We now report the effects of the preconception lifestyle intervention on diet, physical activity and body mass index (BMI) at 5.5?years (range?=?3.7-7.0?years) after the intervention. METHODS:We followed women who participated in the LIFEstyle study, a multicentre RCT in which women with obesity and infertility were assigned to a six-month lifestyle intervention program or prompt infertility treatment (N?=?577). Diet and physical activity 5.5?years later were assessed with an 173-item food frequency questionnaire (N?=?175) and Actigraph triaxial accelerometers (N?=?155), respectively. BMI was calculated from self-reported weight and previously measured height (N?=?179). Dietary intake, physical activity, and BMI in the intervention and control group were compared using multivariate regression models. Additionally, dietary intake, physical activity and BMI of women allocated to the intervention arm with successful weight loss during the intervention (i.e. BMI?
