  • A Smartphone App to Promote Healthy Weight Gain, Diet, and Physical Activity During Pregnancy (HealthyMoms) Protocol for a Randomized Controlled Trial
  • 2019
  • Ingår i: JMIR Research Protocols. - 1929-0748 .- 1929-0748. ; 8:3
  • Tidskriftsartikel (refereegranskat)abstract
    • <p><strong>BACKGROUND:</strong> Excessive gestational weight gain is common and associated with adverse outcomes both in the short and long term. Although traditional lifestyle-based interventions have shown to mitigate excess gestational weight gain, little is known about whether mobile Health (mHealth) apps can promote healthy weight gain, diet, and physical activity during pregnancy.</p><p><strong>OBJECTIVE:</strong> The primary aim of the HealthyMoms trial is to determine the effectiveness of a smartphone app (HealthyMoms) for mitigating excess gestational weight gain during pregnancy. Secondary aims are to determine the effectiveness of the app on dietary habits, physical activity, body fatness, and glycemia during pregnancy.</p><p><strong>METHODS:</strong> HealthyMoms is a two-arm randomized controlled trial. Women are being recruited at routine visits at the maternity clinics in Linköping, Norrköping and Motala, Sweden. Women are randomized to the control or intervention group (n=150 per group). All women will receive standard care, and women in the intervention group will also receive the HealthyMoms smartphone app.</p><p><strong>RESULTS:</strong> Recruitment of participants to the trial was initiated in October 2017, and 190 women have so far completed the baseline measurement. The baseline measures are estimated to be finalized in December 2019, and the follow-up measures are estimated to be completed in June 2020.</p><p><strong>CONCLUSIONS:</strong> This project will evaluate a novel smartphone app intervention integrated with existing maternity health care. If successful, it has great potential to be implemented nationally in order to promote healthy weight gain and health behaviors during pregnancy.</p><p><strong>INTERNATIONAL REGISTERED REPORT IDENTIFIER (IRRID):</strong> DERR1-10.2196/13011.</p>

  • Principles for knowledge co-production in sustainability research
  • 2020
  • Ingår i: Nature Sustainability. - 2398-9629. ; 3:3, s. 182-190
  • Tidskriftsartikel (refereegranskat)abstract
    • <p>Research practice, funding agencies and global science organizations suggest that research aimed at addressing sustainability challenges is most effective when 'co-produced' by academics and non-academics. Co-production promises to address the complex nature of contemporary sustainability challenges better than more traditional scientific approaches. But definitions of knowledge co-production are diverse and often contradictory. We propose a set of four general principles that underlie high-quality knowledge co-production for sustainability research. Using these principles, we offer practical guidance on how to engage in meaningful co-productive practices, and how to evaluate their quality and success. Research addressing sustainability issues is more effective if 'co-produced' by academics and non-academics, but definitions of co-production vary. This Perspective presents four knowledge co-production principles for sustainability research and guides on how to engage in co-productive practices.</p>

  • Energy expenditure differences across lying,sitting, and standing positions in younghealthy adults
  • 2019

  • Tidskriftsartikel (refereegranskat)abstract
    • <p>The time spent in sedentary behaviour represents an important public health burden. Toreduce sedentary time in the general population, the simplest, most effective, and mostaccessible method is to decrease lying and sitting time. We aimed to compare differenceson energy expenditure (EE) across lying, sitting, and standing positions; and to analyse theassociations between the change on EE of changing from one position to another andanthropometric and body composition parameters in young healthy adults. A total of 55(69% women) young healthy adults aged 21.7 ± 2.2 participated in the study. We measuredEE by indirect calorimetry across lying, sitting, and standing positions following the standardprocedures. The EE was significantly higher in standing than in both lying and sitting positions(mean difference: 0.121±0.292 and 0.125±0.241 kcal/min, respectively; all P&lt;0.001),and no differences were observed between lying and sitting positions (P = 1.000). Therewas a negative association between the EE differences in sitting vs. standing position andlean body mass (P = 0.048), yet no associations between EE differences with the rest of theanthropometric and body composition parameters were observed in each position pair studied(all P&gt;0.321). Our findings support the fact that increasing the time spent standing couldbe a simple strategy to slightly increase EE. Therefore, our results have important clinicalimplications including a better monitoring, characterizing, and promoting countermeasuresto sedentariness through low-level physical activities.</p>

  • Congruent Validity of Resting Energy ExpenditurePredictive Equations in Young Adults
  • 2019
  • Ingår i: Nutrients. - 2072-6643 .- 2072-6643. ; :11
  • Tidskriftsartikel (refereegranskat)abstract
    • <p>Having valid and reliable resting energy expenditure (REE) estimations is crucial toestablish reachable goals for dietary and exercise interventions. However, most of the REE predictiveequations were developed some time ago and, as the body composition of the current populationhas changed, it is highly relevant to assess the validity of REE predictive equations in contemporaryyoung adults. In addition, little is known about the role of sex and weight status on the validity ofthese predictive equations. Therefore, this study aimed to investigate the role of sex and weight statusin congruent validity of REE predictive equations in young adults. A total of 132 young healthy adults(67.4% women, 18–26 years old) participated in the study. We measured REE by indirect calorimetrystrictly following the standard procedures, and we compared it to 45 predictive equations. The mostaccurate equations were the following: (i) the Schofield and the “Food and Agriculture Organizationof the United Nations/World Health Organization/United Nations” (FAO/WHO/UNU) equationsin normal weight men; (ii) the Mifflin and FAO/WHO/UNU equations in normal weight women;(iii) the Livingston and Korth equations in overweight men; (iv) the Johnstone and Frankenfieldequations in overweight women; (v) the Owen and Bernstein equations in obese men; and (vi) theOwen equation in obese women. In conclusion, the results of this study show that the best equationto estimate REE depends on sex and weight status in young healthy adults.</p>

    • It is generally believed that estrogens exert their bone sparing effects directly on the cells within the bone compartment. The aim of the present study was to investigate if central mechanisms might be involved in the bone sparing effect of estrogens. The dose-response of central (i.c.v) 17beta-estradiol (E2) administration was compared with that of peripheral (s.c.) administration in ovariectomized (ovx) mice. The dose-response curves for central and peripheral E2 administration did not differ for any of the studied estrogen-responsive tissues, indicating that these effects were mainly peripheral. In addition, ovx mice were treated with E2 and/or the peripheral estrogen receptor antagonist ICI 182,780. ICI 182,780 attenuated most of the estrogenic response regarding uterus weight, retroperitoneal fat weight, cortical BMC and trabecular bone mineral content (P

  • Med accelerometrar kan fysisk aktivitet mätas objektivt- Snabb metodutveckling, men mer kompetens krävs för användning fullt ut i klinisk praxis Physical Activity Measured With Accelerometers
  • 2019
  • Ingår i: Läkartidningen. - 1652-7518. ; 116
  • Forskningsöversikt (refereegranskat)abstract
    • The development of accelerometers has revolutionized measurement of physical activity, and they are used to a large extent in research and have started to be implemented into clinical settings. However, achievement of reliable outcomes requires good methodological knowledge and skills by the user. Otherwise, significant measurement errors may occur, interfering with assessment of the physical activity level in the population, group differences, associations with health parameters or effect of treatments. This paper by the Swedish Network for Objective Measurement of Movement (NORM) provides an overview of physical activity measurement including sections of data collection, processing of raw data into useful metrics and statistical analysis. It targets users of accelerometer in research, health care and national surveys.

  • Global Matrix 3.0 Physical Activity Report Card Grades for Children and Youth: Results and Analysis From 49 Countries
  • 2018
  • Ingår i: Journal of Physical Activity and Health. - HUMAN KINETICS PUBL INC. - 1543-3080 .- 1543-5474. ; 15, s. S251-S273
  • Tidskriftsartikel (refereegranskat)abstract
    • <p>Background: Accumulating sufficient moderate to vigorous physical activity is recognized as a key determinant of physical, physiological, developmental, mental, cognitive, and social health among children and youth (aged 5-17 y). The Global Matrix 3.0 of Report Card grades on physical activity was developed to achieve a better understanding of the global variation in child and youth physical activity and associated supports. Methods: Work groups from 49 countries followed harmonized procedures to develop their Report Cards by grading 10 common indicators using the best available data. The participating countries were divided into 3 categories using the United Nations human development index (HDI) classification (low or medium, high, and very high HDI). Results: A total of 490 grades, including 369 letter grades and 121 incomplete grades, were assigned by the 49 work groups. Overall, an average grade of "C-," "D+," and "C-" was obtained for the low and medium HDI countries, high HDI countries, and very high HDI countries, respectively. Conclusions: The present study provides rich new evidence showing that the situation regarding the physical activity of children and youth is a concern worldwide. Strategic public investments to implement effective interventions to increase physical activity opportunities are needed.</p>
