R Santos et al (2009) .Walking and body mass index in a Portuguese sample of adults: a multilevel analysis. European Journal of Clinical Nutrition 63, 1260–1262;

Physical inactivity is an important risk factor for many chronic diseases. This study examined if there were any realtionship between how much individuals walked and body mass index (BMI). This study looked at 9991 adults (5723 women), aged 37.8 9.5 years, from the 2004 Azorean Physical Activity and Health Study. Walking was assessed with the International Physical Activity Questionnaire, and expressed as minutes per week. BMI was calculated from self-reported weight and height.
The results show that, in both genders, and after adjustments for potential confounders, walking was not a significant predictor of BMI.
