RESUMO

BACKGROUND: Microalgae like Phaeodactylum tricornutum (PT) contain the carotenoid, fucoxanthin, which has been purported to promote fat loss, lower blood lipids, and improve glucose management. This study examined whether dietary supplementation with microalgae extracts from PT containing 4.4 mg/d of fucoxanthin affects changes in body composition or health markers in overweight women during an exercise and diet intervention. MATERIALS AND METHODS: A total of 37 females (28.6 ± 7.9 years, 80.2 ± 14.9 kg, 29.6 ± 3.8 kg/m², 41.4 ± 4.2% fat) fasted for 12 h, donated a fasting blood sample, completed health and mood state inventories, and undertook body composition, health, and exercise assessments. In a counterbalanced, randomized, and double-blind manner, participants ingested a placebo (PL), or microalgae extract of Phaeodactylum tricornutum standardized to 4.4 mg of fucoxanthin (FX) for 12 weeks while participating in a supervised exercise program that included resistance-training and walking (3 days/week) with encouragement to accumulate 10,000 steps/day on remaining days of the week. The diet intervention involved reducing energy intake by about -300 kcal/d (i.e., ≈1400-1600 kcals/d, 55% carbohydrate, 30% fat, 15% protein) to promote a -500 kcal/d energy deficit with exercise. Follow-up testing was performed at 6 and 12 weeks. A general linear model (GLM) with repeated measures statistical analysis was used to analyze group responses and changes from baseline with 95% confidence intervals. RESULTS: Dietary supplementation with microalgae extract from PT containing fucoxanthin for 12 weeks did not promote additional weight loss or fat loss in overweight but otherwise healthy females initiating an exercise and diet intervention designed to promote modest weight loss. However, fucoxanthin supplementation preserved bone mass, increased bone density, and saw greater improvements in walking steps/day, resting heart rate, aerobic capacity, blood lipid profiles, adherence to diet goals, functional activity tolerance, and measures of quality of life. Consequently, there appears to be some benefit to supplementing microalgae extract from PT containing fucoxanthin during a diet and exercise program. Registered clinical trial #NCT04761406.

RESUMO

Excessive body fat is associated with various comorbidities including cardiovascular disease, type 2 diabetes mellitus and certain types of cancer. The search for effective, relatively easy to maintain body-fat reduction interventions has been ongoing. We aimed to review the current literature to assess the effectiveness of high-intensity interval training with and without dietary supplementation on body fat loss, concentration of markers of metabolic health and aerobic capacity of adults with overweight and obesity. Seventy full-text articles were assessed to determine their eligibility and thirteen were included in the review. The methodology of this systematic review was developed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Almost all studies (93%) demonstrated effectiveness of high-intensity interval training of various protocols in reducing body fat, improving metabolic health and aerobic capacity of adults with overweight and obesity. These effects were enhanced by an addition of a dietary supplement, such as green tea or ginger or other. Although combining HIIT with dietary supplementation seem to improve body composition, metabolic health and aerobic capacity in adults with overweight and obesity in some instances to a greater extent than HIIT alone, it does not seem to be necessary to combine these two interventions.

RESUMO

This study aimed to compare the effects of 12-week Bafa Wubu Tai Chi (BW-TC) and traditional He-style Tai Chi (TH-TC) exercise training on physical fitness parameters in overweight university students and to compare the differences in their effects. A total of 81 overweight male university students were randomly assigned to the BW-TC group (N = 27), the TH-TC group (N = 27), and the control group (CG, N = 27). Upper limb grip strength, wall squat, sitting and reaching, 6-minute walk, single-leg stance, and Y-balance were measured at baseline and after 12 weeks of Tai Chi training. There were no significant differences in demographic characteristics and assessment parameters among the groups at baseline (p>0.05). Both BW-TC and TH-TC performed Tai Chi exercise program training lasting 12 weeks, with three sessions per week, each lasting 60 minutes intervention. The changes in mean scores for the sit-and-reach test were 3.11 cm and 4.52 cm, for the wall squat test were 27.56 s and 36.85 s, and for the 6-minute walk test were 22.93 m and 63.22 m, and Y-balance (p<0.05) significantly increased in both BW-TC and TH-TC groups, while the mean score of single-leg stance significantly decreased (p<0.05). Additionally, compared to the BW-TC group, the TH-TC group showed a significant increase in lower limb strength (13.89 s, p = 0.048) and the distance of the Y-balance test in the left posterior medial direction (4.04 cm, p = 0.031). BW-TC and TH-TC interventions effectively improved physical fitness in overweight university students. However, TH-TC showed superior results in lower limb strength improvement.

RESUMO

N-3 long-chain PUFA (LC-PUFA) and probiotics are generally considered to induce health benefits. The objective was to investigate (1) the impact of fish oil and/or probiotics on serum fatty acids (sFA), (2) the interaction of sFA with low-grade inflammation and (3) the relation of sFA to the onset of gestational diabetes mellitus (GDM). Pregnant women with overweight/obesity were allocated into intervention groups with fish oil + placebo, probiotics + placebo, fish oil + probiotics or placebo + placebo in early pregnancy (fish oil: 1·9 g DHA and 0·22 g EPA, probiotics: Lacticaseibacillus rhamnosus HN001 and Bifidobacterium animalis ssp. lactis 420, 1010 CFU, each daily). Blood samples were collected in early (n 431) and late pregnancy (n 361) for analysis of fatty acids in serum phosphatidylcholine (PC), cholesteryl esters (CE), TAG and NEFA with GC and high-sensitivity C-reactive protein and GlycA by immunoassay and NMR spectroscopy, respectively. GDM was diagnosed according to 2 h 75 g oral glucose tolerance test. EPA in PC, CE and TAG and DHA in PC, CE, TAG and NEFA were higher in fish oil and fish oil + probiotics groups compared with placebo. EPA in serum NEFA was lower in women receiving probiotics compared with women not receiving. Low-grade inflammation was inversely associated with n-3 LC-PUFA, which were related to an increased risk of GDM. Fish oil and fish oil + probiotics consumption increase serum n-3 LC-PUFA in pregnant women with overweight/obesity. Although these fatty acids were inversely related to inflammatory markers, n-3 LC-PUFA were linked with an increased risk for GDM.

RESUMO

Providing interventions that facilitate improvement of dietary intake and other health behaviors can improve nutrition-related outcomes in adults with overweight or obesity. Medical nutrition therapy (MNT) behavioral interventions require expertise from registered dietitian nutritionists or international equivalents (dietitians), which no other health care provider can provide for adults with obesity. Current evidence supports the role of MNT behavioral interventions for adults with overweight or obesity as an effective treatment option, when appropriate for and desired by the client. This Academy of Nutrition and Dietetics Position Paper describes potential benefits and concerns regarding dietitian-provided MNT behavioral interventions for adults with overweight and obesity and informs dietitians about implications for practice. This Position Paper is supported by a systematic review examining effectiveness of MNT interventions provided by dietitians and by an evidence-based practice guideline. It is the position of the Academy of Nutrition and Dietetics that MNT behavioral interventions for adults (aged 18 years and older) with overweight or obesity should be a treatment option, when appropriate and desired by the client, to improve cardiometabolic, quality of life, and anthropometric outcomes. Dietitians providing MNT recognize the complex contributors to overweight and obesity, and thus individualize interventions, based on a shared decision-making process, and deliver interventions in an inclusive, compassionate, and client-centered manner. Interventions should include collaboration with an interprofessional team when needed. Dietitians strive to increase health equity and reduce health disparities by advocating and providing opportunities for increased access to effective nutrition care services. This position remains in effect until December 31, 2031.

RESUMO

OBJECTIVES: To compare the effect of different frequency of acupoint thread-embedding on weight loss in subjects with overweight/obesity of spleen deficiency and dampness retention. METHODS: A total of 126 subjects with overweight/obesity of spleen deficiency and dampness retention were randomized into a 2-week group(63 cases, 13 cases dropped out)and a 3-week group(63 cases, 11 cases dropped out, 1 case was eliminated). The two groups were treated with acupoint thread-embedding once every 2 weeks and once every 3 weeks respectively, Zhongwan(CV 12), Shuifen(CV 9), Qihai(CV 6), Guanyuan(CV 4) and bilateral Zhangmen(LR 13), Tianshu(ST 25), Liangmen(ST 21), Daheng(SP 15), Fujie(SP 14), Pishu(BL 20), Yinlingquan(SP 9)were selected. Four times were required in the two groups. Before and after treatment, follow-up after 2 months of treatment completion, the body mass index(BMI), body weight, waist circumference, hip circumference, waist-to-hip ratio, obesity degree, fat percentage(F%), skin fold thickness were observed in the two groups. RESULTS: After treatment and in follow-up, the BMI, body weight, waist circumference, hip circumference, waist-to-hip ratio, obesity degree, F%, skin fold thickness in the two groups were decreased compared with those before treatment (P<0.001, P<0.01), the changes of BMI, body weight, obesity degree, F%, skin fold thickness in the 2-week group were larger than those in the 3-week group(P<0.05, P<0.01, P<0.001). CONCLUSIONS: The effect of acupoint thread-embedding once every 2 weeks on weight loss in subjects with overweight/obesity of spleen deficiency and dampness retention is superior to that once every 3 weeks.

RESUMO

OBJECTIVE: The objective of this study was to assess the effects of an acupuncture-diet program for treatment of overweight and obesity. METHODS: The program consisted of weekly acupuncture sessions combined with a very low-carbohydrate diet in patients with a body mass index (BMI) of 25 kg/m2 or above. Data were collected retrospectively between 2002 and 2021 in seven clinics in Switzerland through automated data extraction of existing medical records. The treatments described are standard care at the facilities where they took place. RESULTS: A total of 11,233 patients were included. In those with a BMI of 25 kg/m2 or above, a positive effect on body weight was noted with a peak average body weight loss of approximately 17.5 kg reached after 7 months. Long-term stabilization was at about 15.5 kg after 18 months. Significant male-female differences (p < 0.01) were observed with women losing less weight. Differences were also noted between overweight, obese and extremely obese patients suggesting a BMI-dependent effect. Maximum weight loss of patients with BMI of 35 kg/m2 or above was 29.8 ± 12 kg, while it was 18.8 ± 8 kg for obese patients (BMI = 30-34.9 kg/m2) and 12 ± 7 kg for overweight patients (BMI = 25-29.9 kg/m2), reflecting a significant overall difference between groups (p < 0.01). Compliance to the protocol by patients and physicians seemed to be another differentiating factor; more adherent patients appeared to lose more weight and preserve body weight loss better over time. CONCLUSION: Although this study lacked a control group and was retrospective and observational in nature, a program of acupuncture combined with a very low-carbohydrate diet appeared to be effective at inducing weight loss among obese patients. The observed weight reduction in this retrospective chart review represents a good starting point for further investigation of this approach via a comparative evaluation.

RESUMO

BACKGROUND: Although increasing evidence has revealed the efficacy of acupuncture in obesity/overweight, actual improvement in metabolism in children and adolescents is unclear. Therefore, we conducted a meta-analysis to evaluate this correlation. METHODS: A comprehensive search was conducted using multiple databases, including Medline, Cochrane, Embase, Web of Science, Chinese Biomedical Literature Database, China National Knowledge Infrastructure, Chinese Scientific Journal Database, and Wan-fang Data, to identify relevant randomized controlled trials published before February 1, 2023. General information and data for the descriptive and quantitative analyses were extracted. RESULTS: Fifteen randomized controlled trials of 1288 obese/overweight children and teenagers were included. All the trials were conducted in China and South Korea. Regarding quality assessment, no other significant risk of bias was found. The acupuncture groups were more likely to have improved metabolic indicators of obesity/overweight than the control groups, in terms of body mass index (standardized mean difference [SMD] = -0.45, 95% confidence interval [CI]: -0.69 to -0.21, I2 = 71.4%), body weight (SMD = -0.48, 95% CI: -0.92 to -0.05, I2 = 84.9%), and serum leptin (SMD = -0.34, 95% CI: -0.58 to -0.10, I2 = 91.8%). The subgroup analysis showed that for body mass index, the results were consistent regardless of the intervention duration, body acupuncture or auricular acupuncture combined with other interventions. CONCLUSION: Our results suggest that acupuncture is effective in improving metabolic outcomes of obese/overweight children and adolescents. Owing to the limited number of trials included in this study, the results should be interpreted with caution.

RESUMO

Polycystic ovary syndrome (PCOS) is the most common female endocrine disorder, and it has two main pathological aspects: reproductive and metabolic. Overweight/obesity is a risk factor in terms of adverse effects during hormone stimulation, a reduced response to ovulation induction regimens, reduced success of IVF, and an increased risk of obstetric complications. To resolve this vicious cycle of pathological events, weight loss and lifestyle modifications are promising strategies. Among these possible approaches, the consumption of a very-low-calorie ketogenic diet (VLCKD) or Mediterranean diet (MD) represents a valid option. In our study, 84 obese/overweight PCOS patients were recruited to evaluate the effects induced by the VLCKD and MD on weight, hormonal, and metabolic parameters. BMI decreased significantly among the VLKCD patients compared to the MD patients (both presenting p values < 0.0001 at 90 and 120 days), and a significant reduction in body circumference was observed. At the same time, HOMA index values statistically decreased for the VLCKD patients compared to those on the MD (p value < 0.001 at 90 days and p value < 0.05 at 120 days), and this phenomenon was also observed for AFC at 90 and 120 days (both p values < 0.001) and AMH at 90 days (p value < 0.05). Interestingly, the ovarian hyperstimulation syndrome (OHSS) incidence was statistically lower in the VLKCD patients compared to the MD patients (p < 0.001). We state that these dietary regimes may improve anthropometric parameters (such as BMI) and women's reproductive health, restore menstrual regularity, and reduce the risk of OHSS. Regarding the different nutritional therapies, the results suggest that the VLCKD is an optimal choice for entry into IVF, especially in terms of the time range in which these results are achieved.

RESUMO

BACKGROUND: The prevalence of overweight or obesity in women of reproductive age continues to increase. A high pre-pregnancy body mass index (BMI) has been shown to increase the risk of pregnancy complications and predispose offspring to childhood obesity. However, little is known about factors affecting women's ability to achieve sustainable weight management and very few studies have applied behavior change theory to qualitative data. AIM: This study aimed to explore barriers and facilitators for weight management among women with overweight or obesity, who wanted to lose weight before pregnancy. METHODS: We conducted semi-structured interviews with 17 women with a BMI ≥ 27 kg/m2, who planned to become pregnant in the near future. Data were analyzed using an abductive approach and the Capability, Opportunity, Motivation, and Behavior model was applied as a conceptual framework. RESULTS: The women's strongest motivator for pre-conception weight loss was their ability to become pregnant. Barriers to successful weight management included their partners' unhealthy behaviors, mental health challenges, competing priorities, and internalized weight stigmatization. The women described careful planning, partners' health behaviors, social support, and good mental health as facilitators for sustainable weight management. CONCLUSION: Our study provides insights into factors affecting weight management among women with overweight or obesity in the pre-conception period. Future interventions on weight management require a holistic approach, including a focus on social support, especially from the partner, and mental health, as well as an effort to limit internalized weight stigma.

RESUMO

The combined exercise with citrulline (CIT) supplementation is a potential adjuvant treatment approach to address the declining body composition and lower limb function of overweight older adults. However, research on this approach is limited. Thus, this study performed a meta-analysis review to explore the effects of combined exercise with CIT supplementation on body composition and lower limb function among overweight older adults. The search strategy and manuscript development of this study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. Eligible studies were first searched through four databases (Web of Science, Scopus, PubMed, and EBSCO) from January 2003 until April 2023, followed by screening. The main inclusion criteria for the article selection are as follows: 1) Randomized Controlled Trial studies; 2) Participants aged over 55; 3) Studies involved exercise with CIT supplementation for the experimental group and exercise with Placebo (PLA) supplementation for the control group; 4) Body composition and lower limb function were measured at pre- and post-intervention. Subsequently, the Cochrane risk of bias assessment tool was utilized to evaluate the selected studies' quality. The Standardized Mean Difference (SMD) was chosen as the suitable effect scale index, and the mean differences of the data from the selected articles were analyzed using Revman 5.4 software with a 95% Confidence Interval (CI). A total of seven studies fulfilled the inclusion criteria and were selected for the meta-analysis. The included studies involved 105 males and 198 females, where 157 belonged to the PLA group and 146 from the CIT group. Significant improvements were observed among overweight older adults with CIT supplementation in 6-Minute Walking Test (6MWT) (P = 0.04, I2 = 4%), SMD (95% CI) = -0.28 (-0.54, -0.01), and Lower Limb Strength (LLS) (P < 0.01, I2 = 30%), SMD (95% CI) = -0.38 (-0.65, -0.12) compared to those with PLA supplementation. Combined exercise with CIT supplementation could be an effective non-pharmaceutical intervention to improve the physical function of overweight older adults by increasing their muscle strength.

RESUMO

The aim of this study was to evaluate the effects of Bafa Wubu Tai Chi (BW-TC) and traditional He-style Tai Chi (TH-TC) exercises on physical health risk factors in overweight male college students and to compare the effectiveness of the two Tai Chi exercise forms in improving these risk factors. METHODS: Eighty-one overweight male university students between the ages of 18 and 23 were randomly assigned in a 1:1:1 ratio to the BW-TC group, TH-TC group, and control group (CG). The Tai Chi exercise training consisted of 12 weeks, three times a week, for 60 min per session. The CG attended three health lectures and maintained their normal study routine. The outcomes were body composition and blood lipids. Data were collected at baseline and post-intervention and analyzed using one-way ANOVA and mixed-design ANOVA. RESULTS: At baseline, there were no significant differences in demographic characteristics and assessed parameters (p > 0.05) among the groups. The BW TC and TH TC groups both significantly decreased their body weight (2.69 kg, 2.04 kg, respectively), body mass index (0.90 kg/m2, 0.67 kg/m2, respectively), body fat percentage (1.46%, 1.10%, respectively), low-density lipoprotein cholesterol (8.82 mg/dL, 9.27 mg/dL, respectively), total cholesterol (8.57 mg/dL, 9.34 mg/dL, respectively) and triglycerides (10.14 mg/dL, 10.63 mg/dL, respectively); and increased their muscle mass (-0.56 kg, -1.13 kg, respectively) and high-density lipoprotein cholesterol (-5.77 mg/dL, -6.37 mg/dL, respectively). Multiple comparisons showed that both Tai Chi groups were significantly better than the CG in improving the evaluated parameters. CONCLUSIONS: Two types of Tai Chi interventions were effective in improving body composition and blood lipids in overweight university students, without significant differences between the two.

RESUMO

Physical activity is essential in weight management, improves overall health, and mitigates obesity-related risk markers. Besides inducing changes in systemic metabolism, habitual exercise may improve gut's microbial diversity and increase the abundance of beneficial taxa in a correlated fashion. Since there is a lack of integrative omics studies on exercise and overweight populations, we studied the metabolomes and gut microbiota associated with programmed exercise in obese individuals. We measured the serum and fecal metabolites of 17 adult women with overweight during a 6-week endurance exercise program. Further, we integrated the exercise-responsive metabolites with variations in the gut microbiome and cardiorespiratory parameters. We found clear correlation with several serum and fecal metabolites, and metabolic pathways, during the exercise period in comparison to the control period, indicating increased lipid oxidation and oxidative stress. Especially, exercise caused co-occurring increase in levels of serum lyso-phosphatidylcholine moieties and fecal glycerophosphocholine. This signature was associated with several microbial metagenome pathways and the abundance of Akkermansia. The study demonstrates that, in the absence of body composition changes, aerobic exercise can induce metabolic shifts that provide substrates for beneficial gut microbiota in overweight individuals.

RESUMO

BACKGROUND: Mindfulness is a meaningful therapeutic target in the treatment of emotional eating in adults with overweight/obesity. Descriptive research mapping relations between mindfulness facets and emotional eating types in treatment-seeking adults with overweight/obesity is needed. METHODS: Cross-sectional relations between mindfulness facets (i.e., acting with awareness, describe, non-judgment, non-reactive, and observe; Five Facet Mindfulness Questionnaire-Short Form) and emotional eating types (i.e., self-reported negative and positive emotional eating; Emotional Eating Scale-Revised, Emotional Appetite Questionnaire) were examined in a treatment-seeking sample of adults with overweight/obesity (N = 63). RESULTS: Significant bivariate correlations revealed negative relations between mindfulness facets and emotional eating types. Multiple regressions revealed that higher describe (ß = - 0.42, p = 0.004) mindfulness was associated with lower self-reported emotional eating-anger/anxiety; higher non-reactive (ß = - 0.31, p = 0.01) and non-judgment (ß = - 0.28, p = 0.02) mindfulness were associated with lower self-reported emotional eating-depression; and higher non-judgment (ß = 0.26, p = 0.04) mindfulness was associated with higher self-reported emotional eating-positive. CONCLUSIONS: Describe, non-judgment, and non-reactive mindfulness were uniquely and significantly associated with eating in response to negative and positive emotions. Results suggest the potential need for intervention programs to be sensitive to the multidimensional nature of mindfulness in the treatment of distinct types of emotional eating in adults with overweight/obesity. LEVEL OF EVIDENCE: V, cross-sectional descriptive study.

RESUMO

BACKGROUND: Obesity is recognised as an important risk factor for obstructive sleep apnea (OSA), with obese individuals at a four times higher risk of being diagnosed with the syndrome. Treating obesity with lifestyle modification is associated with a reduction in the severity of obstructive sleep apnea. Yoga comprises lifestyle modification that includes asana (postures), pranayama (breathing techniques), dhyana (meditation) and guideline principles for healthy living (Yama and Niyama). There is a scarcity of data to evaluate the effect of yoga on OSA. This study was conducted to evaluate the efficacy of Yoga based lifestyle modification on OSA. METHODS: Consenting obese patients (BMI >23) diagnosed with obstructive sleep apnea (OSA) (AHI>5) on Polysomnography (PSG) were enrolled. Eligible patients were randomized into two groups. The control group received counselling for dietary modification (staple Indian) with regular exercise and the active intervention group received Yoga intervention as treatment (OSA module) in addition to similar dietary modification and regular exercise counselling. Polysomnography (PSG) was conducted at baseline and one year follow-up. All patients were evaluated at baseline, six months, and one year for compliance and anthropometric parameters. Additional assessment with Hamilton scales for depression and anxiety, SF-36, and the Pittsburgh sleep quality index was also conducted. RESULTS: A total of 37 eligible patients (19 in the control group and 18 in the yoga group) were recruited for the study. The age [45.73 ± 10.71 vs. 46.22 ± 9.39 years, p = 0.88] and gender [15(78.95%) vs. 12(66.67%), p = 0.48 (males)] distribution was similar in both groups. After adjusting for age and gender, the percentage reduction in weight between the two groups did not reach statistical significance at one year. There was no significant difference in mean AHI between the two groups at one year. However, the number of patients with more than 40% AHI reduction [2/19 (10.52%) vs 8/18 (44.44%), p = 0.02] was significantly higher in the yoga group. Additionally, within the groups, the mean AHI at one year was significantly reduced in the yoga group [51.2 ± 28.0 to 36.8 ± 21.0/hour, p = 0.003], while no significant change was found in the control group [47.2 ± 23 to 38.8 ± 19.9/hour, p = 0.08]. CONCLUSIONS: Lifestyle alteration using Yoga intervention and modification of staple Indian diet may be effective in reducing OSA severity among obese patients. CTRI NUMBER: CTRI/2017/05/008462.

RESUMO

PURPOSE: Updated evidence for the treatment of obesity in cancer survivors includes behavioural lifestyle interventions underpinning at least one theoretical framework. The aim of this systematic review was to assess the effectiveness of theory-based lifestyle interventions for the treatment of overweight/obesity in breast cancer survivors and to report effective behavioural change techniques (BCTs) and components used in these interventions. METHODS: Four databases were searched for RCTs published between database inception and July 2022. The search strategy included MeSH terms and text words, using the PICO-framework to guide the eligibility criteria. The PRISMA guidelines were followed. Risk-of-bias, TIDier Checklist for interventions' content, and the extent of behaviour change theories and techniques application were assessed. To evaluate the effectiveness of interventions, trials were categorised as "very," "quite," or "non" promising according to their potential to reduce body weight, and BCTs promise ratios were calculated to assess the potential of BCTs within interventions to decrease body weight. RESULTS: Eleven RCTs met the inclusion criteria. Seven trials were classified as "very", three as "quite" and one study was "non" promising. Studies' size, design, and intervention strategies varied greatly, but the weight-loss goal in all studies was ≥ 5% of the initial body weight through a 500-1000 kcal/day energy deficit and a gradually increased exercise goal of ≥ 30 min/day. Social Cognitive Theory was the most commonly used theory (n = 10). BCTs ranged from 10 to 23 in the interventions, but all trials included behaviour goal setting, self-monitoring, instructions on the behaviour, and credible source. The risk-of-bias was "moderate" in eight studies and "high" in three. CONCLUSION: The present systematic review identified the components of theory-based nutrition and physical activity behaviour change interventions that may be beneficial for the treatment of overweight/obesity in breast cancer survivors. The strategies mentioned, in addition to reported behavioural models and BCTs, should be considered when developing weight-loss interventions for breast cancer survivors.

RESUMO

Many current treatment options for managing overweight and obesity consist of rather strict diet and exercise regimes that are difficult to implement as a lifelong routine. Therefore, alternative initiatives such as mindful eating and pleasure-oriented physical activity with more focus on implementation and enjoyment are needed to reverse the obesity epidemic. Mindful eating is an approach focusing on inner hunger and satiety signals. YogaDance is a novel exercise approach combining elements of yoga and dance. This study was a randomized controlled trial investigating the individual and combined effects of mindful eating and YogaDance. Participants were healthy, inactive women with overweight or obesity (body mass index ≥ 25 kg/m2 and/or waist circumference ≥ 80 cm) who were randomized to one of four groups for 8 weeks: mindful eating alone, YogaDance alone, the combination of mindful eating and YogaDance, or control. Fat mass was the primary outcome and secondary outcomes included body weight, waist circumference, and other physiological, behavioral, and quality-of-life outcomes. Sixty-one women were included in the study and randomized to mindful eating and YogaDance combined, YogaDance, mindful eating, or control. Fat mass was reduced by 1.3 kg (95% CI [-10.0, 7.3] kg; p = 0.77), 3.0 kg (95% CI [-11.1, 5.1] kg; p = 0.48), and 1.8 kg (95% CI [-10.1, 6.6] kg; p = 0.69) for the mindful eating, YogaDance, and combined mindful eating and YogaDance interventions, respectively, compared to the control, with corresponding effect sizes of 0.15, 0.34, and 0.21. In complete-case analyses, fat percent and waist circumference were reduced whereas mental quality of life and eating behavior were improved for mindful eating and mindful eating and YogaDance combined compared to the control. In conclusion, the study found modest benefits of an 8-week combination of mindful eating and YogaDance, corroborating findings in previous studies on mindful eating, yoga, and dance. However, the study had several limitations that should be taken into consideration, including low power due to a large drop-out as well as low to moderate training load and compliance. The trial was retrospectively registered (ISRCTN87234794).

RESUMO

BACKGROUND: Childhood obesity is a chronic disease with negative physical and psychosocial health consequences. To manage childhood overweight and obesity, integrated care as part of an integrated approach is needed. To realise implementation of this integrated care, practical guidance for policy and practice is needed. The aim of this study is to describe the development of a Dutch national model of integrated care for childhood overweight and obesity and accompanying materials for policy and practice. METHODS: The development of the national model was led by a university-based team in collaboration with eight selected Dutch municipalities who were responsible for the local realisation of the integrated care and with frequent input from other stakeholders. Learning communities were organised to exchange knowledge, experiences and tools between the participating municipalities. RESULTS: The developed national model describes the vision, process, partners and finance of the integrated care. It sets out a structure that provides a basis for local integrated care that should facilitate support and care for children with overweight or obesity and their families. The accompanying materials are divided into materials for policymakers to support local realisation of the integrated care and materials for healthcare professionals to support them in delivering the needed support and care. CONCLUSIONS: The developed national model and accompanying materials can contribute to improvement of support and care for children with overweight or obesity and their families, and thereby help improve the health, quality of life and societal participation of these children. Further implementation of the evidence- and practice-based integrated care while evaluating on the way is needed.
