Currently, the most effective and well-established psychological treatment for BED is cognitive behavioral therapy (CBT) with a remission rate around 80%. CBT is sometimes combined with pharmacotherapy targeting comorbidities associated with BED, such as obesity and depression. Another avenue of treatment that has been less studied is PA. It has been suggested that PA addresses the underlying mechanisms of BED and, thus, increases treatment efficiency. This systematic review provides additional knowledge concerning the benefits of PA in the treatment of individuals with BED including reduction of binge eating (BE) episodes and improvement in other associated comorbidities. Potential mechanisms of action of PA include neurochemical alterations affecting the reward system, reduction of negative affect, and its anorexigenic effects.

ObjectivesPregnancy-related lumbopelvic pain (LPP) is a frequent condition known to significantly affect women in their daily life. The aetiology of pregnancy-related LPP pain is still not clearly established but the mode of conception has been suggested to contribute to LPP. Anxiety related to fertility treatments may be one of the contributing factors. The primary objectives of this study were to determine the evolution of LPP prevalence and severity, and anxiety throughout pregnancy in women who conceived spontaneously (SP) or after fertility treatments (FT). A further aim was to examine the relationship between pregnancy-related LPP severity and anxiety. The secondary objective was to determine the evolution of physical activity and their correlation with the severity of pregnancy-related LPP.DesignProspective cohort study.SettingPregnant women were recruited through physicians’ referrals, posters and newspaper advertisements in the local and surrounding communities (hospital, maternity care clinic, prenatal centres, sports centres, local university) in the city of Trois-Rivières, Canada.Participants59 pregnant women (33 SP and 26 FT) were assessed during the first, second and third trimester of pregnancy.Primary and secondary outcome measuresPregnancy-related LPP prevalence and severity (primary), trait and state anxiety, and physical activity levels (secondary).ResultsThere was no relationship between the mode of conception and the outcome measures. The prevalence and severity of LPP increased over the course of pregnancy (time effect, p<0.0001) whereas trait anxiety decreased from early to mid-pregnancy (time effect, p=0.03). Activity limitations increased throughout pregnancy (time effect, p<0.0001) and physical activity levels decreased (time effect, p<0.0001). The severity of LPP was positively correlated with activity limitations (r=0.51 to 0.55) but negatively with physical activity levels (r=−0.39 to −0.41).ConclusionsMaternal health-related factors, such as LPP, anxiety and physical activity, are not different in women who conceived spontaneously or after fertility treatments. The more LPP was severe, the more the women were physically limited and inactive.

Physical activity (PA) is a part of a healthy pregnancy. To date, no consumer-based activity monitors have been validated with this population. The aim of this study was to validate the Fitbit Zip and Fitbit Flex monitors in free-living conditions with pregnant women using the ActiGraph GT3X as the ?gold standard?. We compared the accuracy of the Fitbit Zip and Fitbit Flex devices in measuring steps, sedentary time and time spent in different activity intensities. Sixteen women in their third trimester of pregnancy wore the ActiGraph GT3X (hip) plus one Fibit Zip (hip) and one Fitbit Flex (wrist) during seven consecutive days. The validity of Fitbit Zip and Fitbit Flex is good, depending on measured parameters. Fitbit Zip is accurate to measure steps whereas Fitbit Flex is precise for MVPA. When choosing between Fitbit Zip and Fitbit Flex monitors, pregnant women should take into account their preferred PA and the parameters they want to measure..

We compared physical activity (PA) levels between pregnant women who conceived naturally (NC) or after fertility treatments (FT) and determined factors predicting prenatal moderate-to-vigorous intensity physical activity (MVPA).The study was conducted in Trois-Rivières (Canada) between October 2015 and July 2018. MVPA and anxiety levels were assessed at each trimester of pregnancy (TR1, TR2 and TR3) using an accelerometer and the State-Trait Anxiety Inventory, respectively. Sociodemographic and reproductive history data were self-reported or collected from medical files. Repeated measures analysis of variance and regression analyses were conducted.Ninety-six women were included in the analyses (58 NC and 38 FT). MVPA levels and daily step counts decreased significantly throughout pregnancy (time effect: F = 28.68, p < 0.0001 and F = 39.18, p < 0.0001, respectively), but NC and FT women presented similar MVPA and daily step counts (no group effect). The decline in PA practice throughout pregnancy was similar in both groups (no interaction effect). At TR1, State (β = −0.272, p = 0.012) and Trait (β = −0.349, p = 0.001) anxiety and past PA (β = 0.483, p < 0.0001) were correlated with MVPA. Past MVPA was also correlated with MVPA at TR2 (β = 0.595, p < 0.0001) and TR3 (β = 0.654, p < 0.0001). Past PA was the strongest predictors of MVPA levels at TR1, TR2, and TR3, predicting 17% (p = 0.0002), 34% (p < 0.0001) and 42% (p < 0.0001), respectively. Overall, our findings suggest that MVPA practice throughout pregnancy is built on past PA practice. Therefore, to be effective at promoting PA throughout pregnancy, obstetric health care providers and fitness professionals should reinforce the importance of being active as early as possible during pregnancy.

Cette étude vise l’approfondissement du lien entre l’estime de soi explicite et implicite, l’estime corporelle et les attitudes alimentaires en comparant 58 femmes atteintes de troubles des conduites alimentaires (TCA) à 54 femmes ayant un trouble anxieux et 96 femmes provenant d’un groupe contrôle. Les résultats montrent que le groupe TCA rapporte davantage d’attitudes alimentaires dysfonctionnelles et d’insatisfaction corporelle. Il présente l’estime de soi explicite et implicite les plus faibles. Chez les TCA, bien que l’estime de soi explicite s’avère le meilleur prédicteur des construits à l’étude, l’estime de soi implicite ajoute une contribution indépendante signifiant l’importance de s’y attarder.The aim of this study is to deepen our understanding of the relationship between explicit self-esteem, implicit self-esteem, body esteem and eating attitudes.  It compares 58 adult women suffering from eating disorders (ED) to 54 women presenting an anxiety disorder and 96 women from a control group on these variables. The ED group presents more dysfunctional eating attitudes and body dissatisfaction as well as lower explicit and implicit self-esteem than the other groups. Among ED, although explicit self-esteem is the best predictor of eating attitudes and body esteem, implicit self-esteem contributes significantly in the explanation of many subscales.  These results indicate the importance of further studies on the subject
