- Aim: The main purpose of this study was to examine the accuracy of a specific pedometer (Silva model Pedometer Plus 56013-3) and accelerometer (Silva model Ex3 plus 56026) in women suffering from obesity. The second aim was to study the impact of BMI, waist and hip circumference and waist-hip ratio on different pedometer and accelerometer positions on the body. Methods: Forty women with a BMI > 30 kg/m 2 wore two pedometers and two accelerometers during a standardized 6 minute walk test. Accelerometer 1 (A1) was placed around the neck. Accelerometer 2 (A2) was attached to the waistband of the woman's trousers in line with left hip, Pedometer 1 (P1) in line with right hip and pedometer 2 (P2) behind back in line with the spine. During the test an assistant manually counted number of steps, using a hand counter as reference for step accuracy. Results: Steps registered with the pedometer were significantly different from actual steps counted. The intra class correlations for the actual steps counted compared with the steps registered were P1 = 0.13, P2 = 0.20, A1= 0.99 and A2 = 0.41. All correlations between the tested pedometer and accelerometer at the different locations and BMI, waist circumference, hip circumference and hip-to waist ratio were little (if any) or low. Conclusions: The accelerometer is more accurate than the pedometer in measuring steps in women suffering from obesity. The location, which gave the most accurate results, was found to be around the neck. © Wiklund et al.

Journal article (peer-reviewed)abstract
- Abstract: Background and purpose: Obesity is a major global health problem today and the only evidence-based method leading to a long-lasting weight reduction is bariatric surgery. Physical activity improves health, decreases the incidence of several diseases and may influence weight loss outcome after bariatric surgery. Knowledge regarding how patients experience physical activity after bariatric surgery could provide us with better tools to enhance physically active. Methods: The aim of the present study was to describe how patients experience physical activity one year after bariatric surgery. An inductive qualitative content analysis was used to analyse semi-structured interviews with twenty-four patients one year after bariatric surgery. Results: The main findings emerged in four overarching themes: “Hindrances of physical activity”, “Physical activity with a less obese body implies achievement”, “Coming to an understanding of the benefits of physical activity” and “Need of support”. Conclusion: According to our findings patients experience both achievements and hinders with regard to physical activity one year after surgery. Patients had an increased understanding of the benefits of physical activities, but support appears necessary to obtain and maintain a suitable level.

Physical Fitness and Physical Activity in Swedish Women before and onePhysical Fitness and Physical Activity in Swedish Women before and one Year after Roux-en-Y Gastric Bypass Surgery
- 2014
-
In: The Open Obesity Journal. - : Bentham Science Publishers Ltd.. - 1876-8237. ; 6, s. 38-43
-
Journal article (peer-reviewed)abstract
- Aim: To investigate physical fitness, physical activity level and time spent sitting in Swedish women before and one year after laparoscopic Roux-en-Y Gastric Bypass surgery (LRYGB). Method: Thirty-seven women (age: 41.2±9.6 years and Body Mass Index (BMI): 42±6.5 kg/m2) were tested before and one year after LRYGB. (BMI: 30.5±5.8 kg/m2). Physical fitness was assessed using the six minute walk test (6MWT), and three muscular endurance and one handgrip test. Physical activity level and sitting time were assessed using the short form of the International Physical Activity Questionnaire (IPAQ). Results: One year after surgery the mean distance walked during 6MWT increased from 532 m to 599 m (p=<0.001) and the muscular endurance was significantly improved (p0.016), while no statistical significant difference was found in grip force compared to pre-operatively. After surgery, the women walked significantly more minutes/week (p=0.018) and increased their level of moderate (p=0.039) and vigorous (p=0.033) physical activity, but there were no significant differences in sitting time (p=0.206) compared to preoperatively. Conclusions: The physical activity level as well as physical fitness increased while grip strength remained same in Swedish women one year after LRYGB, compared to before surgery. The improved physical fitness and the considerable weight loss are important factors in reducing the risk of developing lifestyle associated diseases and risk of premature death in this group of women. But even if both physical activity and physical fitness increased at group level one year after LRYGB, some individuals still needed to be more physically active and to enhance the physical fitness level. These patients might benefit from physiotherapy to be able to be more physically active.

Physical Function and Health Related Quality of Life Before and 18 Months after Bariatric Surgery
- 2015
-
In: The Open Obesity Journal. - : Bentham Science Publishers Ltd.. - 1876-8237. ; 7, s. 12-16
-
Journal article (peer-reviewed)abstract
- Introduction: The mobility disability experienced by people with obesity is well known and has been found to be associated with reduced health related quality of life (HRQoL) compared to people without obesity. Research is lacking related to the patients experiences that how their capacity to perform various daily physical activities and HRQoL are affected by weight loss following bariatric surgery. Aim: To evaluate patients’ experiences of their HRQoL and physical function before and 18 months after laparoscopic Roux-en-Y Gastric Bypass surgery (LRYGB). Method: A series of 70 patients filled in one HRQoL questionnaire, the EQ-5D (including EQ VAS and EQ-5D descriptive system) and two self-assessment questionnaires that evaluate disability by assessing activity and participation limitations, the Disability Rating Index (DRI) and a questionnaire with five disease-specific questions. Results: All activities, in both DRI as well as the five disease-specific questions were experienced as significantly less difficult to perform postoperatively than preoperatively (p<0.05). In this study, the median (min, max) EQ VAS score was 60 (20, 100) mm preoperatively and 80 (20, 100) mm postoperatively (100 = best imaginable health; 0 = worst imaginable health). The difference between pre- and postoperative EQ VAS was significant (p<0.001). Conclusion: Both the HRQoL and the self experienced ability to perform various daily physical activities increased significantly 18 months after LRYGB compared to preoperatively.
