RESUMO

BACKGROUND: The anthroposophical philosophy is a holistic educational and lifestyle approach. Limited information exists on the health-promoting behavioral norms and obesity rates among children living anthroposophical vs. conventional lifestyles. AIMS: This study aims to compare the prevalence of childhood obesity, and parents' perceptions of their children's food environment, between anthroposophical and conventional education systems. METHODS: We performed a cross-sectional analysis of the National Anthropometric Measurement Survey for first grade students in Israel, comparing anthroposophical schools with matched conventional schools. Additionally, an online survey was distributed among parents of children in both school systems, assessing children's eating norms and dietary intake. RESULTS: Overweight and obesity rates were higher among students in conventional schools (n = 205,500) compared to anthroposophical schools (n = 2247) (11.2% vs. 9.6%, and 7.8% vs. 4.8%, respectively; Pv < 0.001). Anthroposophical schools were perceived by more parents to have health-promoting curricula, health promoting teacher behavior, and health promoting social dietary norms, while their children's dietary intake was perceived as healthier both in school and in the after-school, social, and familial environment (Pv < 0.001). CONCLUSIONS: Children in anthroposophical education exhibited lower overweight and obesity rates, and engaged in more health-promoting behaviors. Further research is needed to explore the relationship between the anthroposophical lifestyle and childhood obesity, and to identify effective anthroposophical strategies for health promotion among children.

RESUMO

BACKGROUND: Obesity and unemployment are complex social and health issues with underlying causes that are interconnected. While a clear link has been established, there is lack of evidence on the underlying causal pathways and how health-related interventions could reduce obesity and unemployment using a holistic approach. OBJECTIVES: The aim of this realist synthesis was to identify the common strategies used by health-related interventions to reduce obesity, overweight and unemployment and to determine for whom and under what circumstances these interventions were successful or unsuccessful and why. METHODS: A realist synthesis approach was used. Systematic literature searches were conducted in Cochrane library, Medline, SocIndex, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Scopus, and PsychInfo. The evidence from included studies were synthesised into Context-Mechanism-Outcome configurations (CMOcs) to better understand when and how programmes work, for which participants and to refine the final programme theory. RESULTS: A total of 83 articles met the inclusion criteria. 8 CMOcs elucidating the contexts of the health-related interventions, underlying mechanisms and outcomes were identified. Interventions that were tailored to the target population using multiple strategies, addressing different aspects of individual and external environments led to positive outcomes for reemployment and reduction of obesity. CONCLUSION: This realist synthesis presents a broad array of contexts, mechanisms underlying the success of health-related interventions to reduce obesity and unemployment. It provides novel insights and key factors that influence the success of such interventions and highlights a need for participatory and holistic approaches to maximise the effectiveness of programmes designed to reduce obesity and unemployment.

RESUMO

Excess weight causes disorders in locomotor, cardiorespiratory and reproductive systems and increases the incidence of endocrinopathies, as well it can often cause dyslipidemias, leading to atherosclerosis. Aims: Report the evolution of homeopathic treatment in 4 overweight patients, being 2 female dogs and 2 female rabbits with hypertriglyceridemia, analyzing the values in biochemical test. Methodology:Homeopathic treatment was chosen, based on the principle of similitude, using Cholesterinum due to its action to decrease cholesterol and triglyceride levels. Results:The same protocol was made for all of the four patients, included 2 globules of Cholesterinum 30CH direct in its mouth, every 12 hours for 30 days. The first dog attended on 01/09/2019, and presented 328 mg/dL of triglycerides, decreasing this level to 132 mg/dL after just one-monthtreatment. The second dog attended on 04/05/2019, presented higher hypertriglyceridemia with 617 mg/dL that decreased to 259 mg/dL. Likewise, on 02/06/2019, the first rabbit attended, presented 445mg/dL of triglycerides, which were reduced to 337 mg/dL, while the second rabbit, on 06/27/2019, presented 372 mg/dL of triglycerides, decreasing to 274 mg/dL after. Although the values of cholesterol in all patients were in agreement with the reference, the treatment still proved improvements. In the beginning of the treatment, the first dog showed 207 mg/dL of cholesterol and in the end, it reduced to 170 mg/dL, as well with the second dog with 218 mg/dL in the beginning and 200 mg/dL after. Regarding rabbits, the first one presented an initialvalue of 60 mg/dL, which decreased to 52 mg/dL, while the second started with 57 mg/dL and went to 41 mg/dL. Conventionally, Bezafibrate is indicated as a lipid-lowering agent, but it is contraindicated in patients with liver or kidney failure, vesicular diseases,and for pregnant or lactating. Conclusion:Dyslipidemia can be controlled with High dilution. (The exposed information is consented by the tutors)

RESUMO

Older adults (≥65 years) are the fastest growing population group. Thus, ensuring nutritional well-being of the 'over-65s' to optimise health is critically important. Older adults represent a diverse population - some are fit and healthy, others are frail and many live with chronic conditions. Up to 78% of older Irish adults living independently are overweight or obese. The present paper describes how these issues were accommodated into the development of food-based dietary guidelines for older adults living independently in Ireland. Food-based dietary guidelines previously established for the general adult population served as the basis for developing more specific recommendations appropriate for older adults. Published international reports were used to update nutrient intake goals for older adults, and available Irish data on dietary intakes and nutritional status biomarkers were explored from a population-based study (the National Adult Nutrition Survey; NANS) and two longitudinal cohorts: the Trinity-Ulster and Department of Agriculture (TUDA) and the Irish Longitudinal Study on Ageing (TILDA) studies. Nutrients of public health concern were identified for further examination. While most nutrient intake goals were similar to those for the general adult population, other aspects were identified where nutritional concerns of ageing require more specific food-based dietary guidelines. These include, a more protein-dense diet using high-quality protein foods to preserve muscle mass; weight maintenance in overweight or obese older adults with no health issues and, where weight-loss is required, that lean tissue is preserved; the promotion of fortified foods, particularly as a bioavailable source of B vitamins and the need for vitamin D supplementation.

RESUMO

Adolescence is a pivotal point in the life course, characterised by transformative physical, cognitive, and emotional growth, an openness to change, and a drive to reshape the social environment. It offers unique opportunities to adopt changes in diet and physical activity that can persist into later life. Yet pre-existing nutritional problems, including micronutrient deficiencies, food insecurity, and poor-quality diets, persist at the same time as adolescents face the rapid emergence of an obesity epidemic. Adolescent growth and nutrition has been largely overlooked in intervention and policy research. Most intervention studies have emphasised micronutrient supplementation, with few taking into account the multiple drivers of adolescent diets. This Series paper highlights that effective interventions and policies will need to cut across sectors; be supported by multifaceted and multilevel policy; and extend across education, health, food systems, social protection, and digital media. Better data standardisation and systems will be essential in coordinating and monitoring these responses. In a context of shifts in planetary ecosystems and commercial drivers, resilient food systems will need to both ensure access to healthy and affordable foods and provide the infrastructure and incentives for continuing physical activity. Intergenerational partnerships with young people will be essential in bringing about transformative change and ensuring that food policies reflect their needs and aspirations.

RESUMO

Data concerning overweight and obesity in children and adolescent populations are alarming and represent one of the most serious public health problems of our time. Moreover, it is demonstrated that the school environment may play an important role in health promotion with regard to nutritional aspects. This article reports the results of a study conducted in the Apulia region (Southern Italy), aimed at providing an integrated surveillance of the behaviors related to nutrition habits in students and the hygienic and nutritional conditions of the school's canteens attended by enrolled students. To this purpose, a sample of 501 students attending primary school (third class-children approximately eight years old) replied to a validated questionnaire, and official controls (OC), of both food and nutritional safety, were performed in 22 primary schools. A team of healthcare professionals carried out the study, and the implementation of all the prescribed improvement actions were subsequently verified through follow-up OC. The results of our study show a critical situation in the student sample, with 41.3% of children having a weight excess (overweight or obesity). With regard to the children's behaviors, only 59.8% of children ate at least one fruit or had a fruit juice for breakfast, and 10.8% did not have breakfast at all. Overall, 40.1% of the total children played outdoors the afternoon before the survey and 45% reported going to school on foot or by bicycle. During the afternoon, 83.5% of the sample watched television or used video games/tablets/mobile phones, while 42.3% played sports. The schools had an internal canteen with on-site preparation of meals in 36.4%, the remaining 63.6% received meals from external food establishments. With regard to OC, for the hygienic-sanitary section, eleven prescriptions were issued, in the great part related to the structure and organization of the canteen. For the nutritional section, nine corrective actions were prescribed, mainly related to official documents and management. The follow-up OC showed that all prescriptions were subsequently addressed. Eating at school was less frequent among obese and overweight students compared with those with normal weight. Although this evidence needs to be further confirmed, it highlights the potential role that the school canteens may play in health promotion and prevention of nutritional disorders. On the other hand, in order to fulfill its health promotion task, the school canteens have to comply with official regulations and guidelines; therefore, OC during the management of the food service at school are needed.

RESUMO

Nutritional factors (diet, weight, alcohol, physical activity) are identified as factors having an impact on the onset of several cancer sites. Less abundant scientific data also underline their impact on the tumor progression. A review of the scientific literature was carried out by a group of experts established by the French National Cancer Institute (INCa) to better document the influence of nutritional factors during and after cancer on outcomes such as overall mortality, cancer specific mortality, recurrence, second primary cancers and quality of life. This analysis of the literature completes messages of reduction of alcohol consumption, prevention of undernutrition or excess weight and adherence to dietary recommendations, avoiding the use of dietary supplements, fasting or restrictive diets and strengthens messages promoting the practice of physical activity and the fight against sedentary lifestyle.

RESUMO

BACKGROUND: Mindful eating has been introduced as a strategy to help prevent overweight and obesity. AIM: The purpose of this research was to develop a simple system dynamics model to investigate the impact of different interventions on population level mindfulness, mindful eating and healthy weight over a 10-year period. METHODS: A model was constructed and outcomes analysed following the addition of four mindful eating interventions, including decreasing busyness (formal and informal work), promotion of mindful eating (e.g. classes and media), promotion of mindfulness, reduction of external eating cues (decreased portion sizes and variety) or a combination of all interventions. RESULTS: The model projected that if the current situation was to continue over the next 10-year period, there would be a small decrease of 0.6% in the healthy-weight population despite a 42% increase in people practising mindfulness and 40% increase in people eating mindfully. Of the four interventions introduced, decreasing busyness had the greatest impact on the number of people practising mindfulness, eating mindfully and of a healthy weight. However, when all four interventions were introduced together this resulted in the greatest (19%) increase in the proportion of healthy-weight people. CONCLUSIONS: The study suggests that mindful eating can be improved through intervention, however, the interventions will not greatly contribute to improving the healthy-weight population unless implemented in combination.

RESUMO

Increasing prevalence of obesity poses challenges for public health. Men have been under-served by weight management programs, highlighting a need for gender-sensitized programs that can be embedded into routine practice or adapted for new settings/populations, to accelerate the process of implementing programs that are successful and cost-effective under research conditions. To address gaps in examples of how to bridge the research to practice gap, we describe the scale-up and scale-out of Football Fans in Training (FFIT), a weight management and healthy living program in relation to two implementation frameworks. The paper presents: the development, evaluation and scale-up of FFIT, mapped onto the PRACTIS guide; outcomes in scale-up deliveries; and the scale-out of FFIT through programs delivered in other contexts (other countries, professional sports, target groups, public health focus). FFIT has been scaled-up through a single-license franchise model in over 40 UK professional football clubs to 2019 (and 30 more from 2020) and scaled-out into football and other sporting contexts in Australia, Canada, New Zealand, England and other European countries. The successful scale-up and scale-out of FFIT demonstrates that, with attention to cultural constructions of masculinity, public health interventions can appeal to men and support them in sustainable lifestyle change.

RESUMO

BACKGROUND: Overweight and obesity are the result of a complex interaction between genetic and environmental factors, which begins prenatally. AIM: To analyse an intervention based on play as a means of improving the body composition of children who are overweight or obese. METHODS: The Kids-Play study is a randomized clinical trial (RCT) consisting of 49 children aged 8-12 years on a nine-month intervention programme based on physical activity, play and nutritional advice. Controls had another 49 children, who received only nutritional advice. RESULTS: The play-based intervention achieved a moderate-vigorous level of physical activity in the study group of 81.18 min per day, while the corresponding level for the control group was only 37.34 min. At the start of the intervention, the children in the study group had an average body fat content of 41.66%, a level that decreased to 38.85% by the end of the programme. Among the control group, body fat increased from 38.83% to 41.4% during the same period. CONCLUSIONS: The intervention programme considered, based on both play and nutritional recommendations, produced a decrease in body fat among children aged 8-12 years. However, the control group, which received only nutritional recommendations, experienced an increase in body weight.

RESUMO

The primary aim of our study was to determine the influence of taking chromium plus carnitine on insulin resistance, with a secondary objective of evaluating the influences on lipid profiles and weight loss in overweight subjects with polycystic ovary syndrome (PCOS). In a 12-week randomized, double-blind, placebo-controlled clinical trial, 54 overweight women were randomly assigned to receive either supplements (200 µg/day chromium picolinate plus 1000 mg/day carnitine) or placebo (27/each group). Chromium and carnitine co-supplementation decreased weight (- 3.6 ± 1.8 vs. - 1.0 ± 0.7 kg, P < 0.001), BMI (- 1.3 ± 0.7 vs. - 0.3 ± 0.3 kg/m2, P < 0.001), fasting plasma glucose (FPG) (- 5.1 ± 6.0 vs. - 1.1 ± 4.9 mg/dL, P = 0.01), insulin (- 2.0 ± 1.4 vs. - 0.2 ± 1.2 µIU/mL, P < 0.001), insulin resistance (- 0.5 ± 0.4 vs. - 0.04 ± 0.3, P < 0.001), triglycerides (- 18.0 ± 25.2 vs. + 5.5 ± 14.4 mg/dL, P < 0.001), total (- 17.0 ± 20.3 vs. + 3.6 ± 12.0 mg/dL, P < 0.001), and LDL cholesterol (- 13.3 ± 19.2 vs. + 1.4 ± 13.3 mg/dL, P = 0.002), and elevated insulin sensitivity (+ 0.007 ± 0.005 vs. + 0.002 ± 0.005, P < 0.001). In addition, co-supplementation upregulated peroxisome proliferator-activated receptor gamma (P = 0.02) and low-density lipoprotein receptor expression (P = 0.02). Overall, chromium and carnitine co-supplementation for 12 weeks to overweight women with PCOS had beneficial effects on body weight, glycemic control, lipid profiles except HDL cholesterol levels, and gene expression of PPAR-γ and LDLR.

RESUMO

INTRODUCTION: The purpose of this study was to develop and validate a predictive model for the early identification of nonresponders to a 12-month lifestyle change program in clinical practice. METHODS: Investigators identified lifestyle change program participants in the electronic health records of a large healthcare delivery system between 2010 and 2017. Nonresponse was defined as weight gain or no weight loss at 12 months from the program initiation (baseline). Logistic regression with percentage weight change at 2-12 weeks from baseline was used as an independent predictor of nonresponse. Baseline demographics and clinical characteristics were also tested as potential predictors. The authors performed ten-fold cross-validation for model assessment and examined model performance with the area under the receiver operating characteristic curve, sensitivity, specificity, and positive and negative predictive values. The analyses were conducted in 2019. RESULTS: Among 947 program participants, 30% were classified as nonresponders at 12 months. The model with the best discrimination of responders from nonresponders included weight change at 12 weeks from baseline as the sole predictor (area under the receiver operating characteristic curve, 0.789). Sensitivity and positive predictive value were maximized at 0.56 (specificity and negative predictive value, 0.81 each). CONCLUSIONS: In a cohort of lifestyle change program participants from clinical practice, percentage weight change at 12 weeks from baseline can serve as a single indicator of nonresponse at the completion of the 12-month program. Clinicians can easily apply this algorithm to identify and assess participants in potential need of adjunctive or alternative therapy to maximize treatment outcomes.

RESUMO

Childhood obesity is a global public health challenge. Early prevention, particularly during the first 1000 days, is advocated. Health professionals have a role to play in obesity prevention efforts, in part due to the multiple routine contacts they have with parents. We synthesized the evidence for the effectiveness of obesity prevention interventions delivered by health professionals during this time period, as reviews to date have not examined effectiveness by intervention provider. We also explored what behaviour change theories and/or techniques were associated with more effective intervention outcomes. Eleven electronic databases and three trial registers were searched from inception to 04 April 2019. A total of 180 studies, describing 39 trials involving 46 intervention arms, were included. While the number of interventions has grown considerably, we found some evidence for the effectiveness of health professional-delivered interventions during the first 1000 days. Only four interventions were effective on a primary (adiposity/weight) and secondary (behavioural) outcome measure. Twenty-two were effective on a behavioural outcome only. Several methodological limitations were noted, impacting on efforts to establish the active ingredients of interventions. Future work should focus on the conduct and reporting of interventions.

RESUMO

A dose of proanthocyanidins with satiating properties proved to be able to limit body weight increase several weeks after administration under exposure to a cafeteria diet. Here we describe some of the molecular targets and the duration of the effects. We treated rats with 500 mg grape seed proanthocyanidin extract (GSPE)/kg BW for ten days. Seven or seventeen weeks after the last GSPE dose, while animals were on a cafeteria diet, we used reverse transcriptase-polymerase chain reaction (RT-PCR) to measure the mRNA of the key energy metabolism enzymes from the liver, adipose depots and muscle. We found that a reduction in the expression of adipose Lpl might explain the lower amount of adipose tissue in rats seven weeks after the last GSPE dose. The liver showed increased expression of Cpt1a and Hmgs2 together with a reduction in Fasn and Dgat2. In addition, muscle showed a higher fatty oxidation (Oxct1 and Cpt1b mRNA). However, after seventeen weeks, there was a completely different gene expression pattern. At the conclusion of the study, seven weeks after the last GSPE administration there was a limitation in adipose accrual that might be mediated by an inhibition of the gene expression of the adipose tissue Lpl. Concomitantly there was an increase in fatty acid oxidation in liver and muscle.

RESUMO

BACKGROUND: Since 2006 there has been substantial long-term investment in school-based child obesity prevention programs in New South Wales (Australia). Whether these programs have led to population level improvements in children's weight status and weight-related behaviors are yet to be determined. The purpose of this study was to describe changes in children's weight status and weight-related behaviors, including Indigenous children, who are at greater risk of poorer health outcomes than non-Indigenous children. METHODS: Representative cross-sectional population surveys conducted in 2010 and 2015 among children age 5-16 years (n = 15,613). Objective measurements included height, weight, waist circumference, cardiorespiratory fitness, and fundamental movement skills. Indigenous status and indicators of weight-related behavior (i.e., diet, physical activity, school travel, screen-time) were measured by questionnaire with parents responding for children age <10 years and self-report by children age ≥10 years. RESULTS: The prevalences of overweight/obesity, obesity and abdominal obesity were higher in 2015, than 2010, and higher among Indigenous than non-Indigenous children at both timepoints. There were some small positive changes towards healthier weight-related behaviors between surveys among all children, but many unhealthy weight-related behaviors remain highly prevalent. The magnitude of changes and the 2015 prevalences of weight-related behaviors were generally similar for Indigenous and non-Indigenous children. CONCLUSIONS: Schools play an important role in health promotion, but our findings suggest the current approaches need re-thinking. Upstream factors that shape weight-related behaviors such as the regulation of the food industry and food environment, urban, neighborhood and public transport planning must be including in solutions to ensure populations can eat healthily and be physical active.

RESUMO

In Mexico, data from the last National Health and Nutrition Survey (2016) described the increase in the prevalence of overweight and obesity in school-aged children (33.2%). Obesity prevention strategies have not been effective, and currently, Mexico has one of the highest prevalence of childhood obesity. Thus, there is an urgent need to develop strategies that can prevent childhood obesity and also to avoid these children to remain overweight/obese through adulthood. The objective of this study was to provide a step-by-step description of the design, implementation and evaluation of an intervention plan for Mexican mothers of school aged children to promote healthy eating and to prevent childhood obesity. The program Niño Sano Adulto Sano was developed using the Intervention Mapping Approach and the Social Cognitive Theory frameworks to provide Mexican mothers with knowledge and skills to positively modify their children's food behavior, thus preventing future weight gain. The program was developed, piloted and delivered to the target population with positive results on the mothers' nutrition knowledge and children's BMI. Intervention Mapping and Social Cognitive Theory are useful models to design and deliver an intervention that provides a holistic approach to promote healthy eating.

RESUMO

Endothelial dysfunction is recognized as an early sign of systemic atherosclerosis, and it represents a therapeutic target to prevent long-term cardiovascular (CV) consequences. Alpha-lipoic acid (ALA) is a commonly used dietary supplement exerting anti-oxidant and anti-inflammatory effects. We investigated whether a three-month treatment with ALA improves endothelial function, as assessed by flow-mediated dilation (FMD) of the brachial artery, and clinical and metabolic risk factors in overweight/obese youths. We enrolled 67 overweight/obese children, and 22 normal-weight metabolically healthy controls. Overweight/obese youths were randomly allocated in a double-blinded manner to receive ALA (n = 34) or placebo (n = 33). Of these, 64 (32 ALA, 32 placebo) completed the follow-up. At baseline, in ALA and placebo groups, FMD was similar, but lower as compared with that in controls (p = 0.045). At three months, within the ALA and placebo groups, FMD did not change significantly. However, the basal and peak diameter of brachial artery significantly increased after ALA treatment as compared to placebo (p = 0.036 and p = 0.01, respectively). There were no significant within- and between-group changes for anthropometric and metabolic variables. The results show that ALA supplementation improves vascular tone and may have a beneficial effect on CV health in overweight/obese youths.

RESUMO

OBJECTIVE: Functional Imagery Training (FIT) is a new brief motivational intervention based on the Elaborated Intrusion theory of desire. FIT trains the habitual use of personalised, affective, goal-directed mental imagery to plan behaviours, anticipate obstacles, and mentally try out solutions from previous successes. It is delivered in the client-centred style of Motivational Interviewing (MI). We tested the impact of FIT on weight loss, compared with time- and contact-matched MI. DESIGN: We recruited 141 adults with BMI (kg/m²) ≥25, via a community newspaper, to a single-centre randomised controlled trial. Participants were allocated to one of two active interventions: FIT or MI. Primary data collection and analyses were conducted by researchers blind to interventions. All participants received two sessions of their allocated intervention; the first face-to-face (1 h), the second by phone (maximum 45 min). Booster calls of up to 15 min were provided every 2 weeks for 3 months, then once-monthly until 6 months. Maximum contact time was 4 h of individual consultation. Participants were assessed at Baseline, at the end of the intervention phase (6 months), and again 12 months post-baseline. MAIN OUTCOME MEASURES: Weight (kg) and waist circumference (WC, cm) reductions at 6 and 12 months. RESULTS: FIT participants (N = 59) lost 4.11 kg and 7.02 cm of WC, compared to .74 kg and 2.72 cm in the MI group (N = 55) at 6 months (weight mean difference (WMD) = 3.37 kg, p < .001, 95% CI [-5.2, -2.1], waist-circumference mean difference (WCMD) = 4.3 cm, p < .001, 95% CI [-6.3,-2.6]). Between-group differences were maintained and increased at month 12: FIT participants lost 6.44 kg (W) and 9.1 cm (WC) compared to the MI who lost .67 kg and 2.46 cm (WMD = 5.77 kg, p < .001, 95% CI [-7.5, -4.4], WCMD = 6.64 cm, p < .001, 95% CI [-7.5, -4.4]). CONCLUSION: FIT is a theoretically informed motivational intervention which offers substantial benefits for weight loss and maintenance of weight reduction, compared with MI alone, despite including no lifestyle education or advice.

RESUMO

BACKGROUND: Intermittent dieting may be an alternative to continuous dieting for weight reduction. OBJECTIVE: To evaluate the effect of intermittent dieting versus continuous dieting on weight and body composition in overweight or obese adults. DESIGN: A systematic review and meta-analysis of randomized controlled trials (RCTs). Five databases were searched until February 2018 for RCTs comparing intermittent versus continuous dieting. Intermittent dieting consisted of two types: regular intermittent was caloric restriction interspersed with days of weight maintenance or ad libitum eating; intensified intermittent was caloric restriction interspersed with days of even lower caloric restriction. Continuous was continual caloric restriction. Primary outcomes were weight, body fat, lean mass, waist circumference, hip circumference, and energy expenditure. Data were pooled by the inverse variance method using random-effects models and expressed as mean differences (MD) and their 95% confidence intervals (CI). RESULTS: Nine trials met the inclusion criteria (n = 782), six comparing regular intermittent vs continuous (n = 553), and three comparing intensified intermittent vs continuous (n = 229). Populations were heterogeneous: obese only in five studies, and overweight or obese (mixed) in four studies. Lean mass was significantly lower in regular intermittent vs continuous (MD -0.86 kg; 95% CI -1.62 to -0.10; p = 0.03). No differences were found for the remaining outcomes for both comparisons (regular intermittent or intensified intermittent vs continuous). There was low heterogeneity of effects across trials. Subgroup effects by time to follow-up, gender, per-protocol versus intention-to-treat, enforced exercise, and diabetes were similar to main analyses. CONCLUSIONS: This systematic review in obese and overweight individuals showed that regular intermittent dieting decreased lean mass compared to continuous dieting. There were no differences in effects for either intermittent vs continuous interventions across all other outcomes. In contrast to previous systematic reviews, this study suggested that lean mass is better preserved in continuous dieting compared to regular intermittent dieting.

RESUMO

OBJECTIVE: Assess impact of multimodality weight gain prevention intervention. METHODS: Randomized clinical trial among 39 overweight young Puerto Rico college students using 10 weekly peer-support sessions promoting dietary, physical activity, and other lifestyle changes enhanced by stress-reduction and mindfulness approaches. Body mass index (BMI) and self-reported behaviors were measured at baseline and at 10 weeks and 6 months after baseline. RESULTS: At the completion of the intervention, BMIs in the experimental arm were 0.8 units lower than at baseline (z = -3.0; P = .008) and 1.2 lower at 6 months after baseline (z = -4.1; P < .001); BMIs in the control arm were 0.7 higher (z = 2.7; P = .02) at 10 weeks and 0.8 higher at 6 months (z = 3.1; P = .005). Group × time interaction confirmed that BMI differed significantly over time between arms (χ2 = 26.9; degrees of freedom = 2; P < .001). Analysis of behavioral changes was mostly inconclusive although the experimental arm reported a considerable increase in walking at 10 weeks. Qualitative data suggested that yoga and mindfulness components were particularly useful for motivating participants to maintain healthier lifestyle patterns. CONCLUSIONS: Body mass index in the experimental arm decreased at the end of intervention and was maintained at 6 months' follow-up.
