Guazzelli Marques, C, de Piano Ganen, A, Zaccaro de Barros, A, Thomatieli Dos Santos, RV, Dos Santos Quaresma, MVL
Clinical nutrition (Edinburgh, Scotland). 2020;(3):694-704
Abstract
Obese individuals present adverse changes in the diversity and composition of the gut microbiota, leading to alterations in energy balance, lipid metabolism, endocrine disturbances, and low-grade chronic systemic inflammation increases. Probiotic supplementation appears to change gut microbiota by decrease gut permeability, inflammation, and metabolic disorders, creating a promising environment to weight loss. This revision resumes the main findings of probiotic supplementation and weight loss that contributed to building the current background linking changes in gut microbiota profile and with obesity.

Africa's Changing Food Environments and Nutritional Effects on Adults and Children.
Demmler, KM, Qaim, M
World review of nutrition and dietetics. 2020;:31-41
Abstract
Many low- and middle-income countries (LMICs) are experiencing profound changes in food environments, including a rapid growth of supermarkets and other modern retailers. Changing food environments can influence people's diets, nutrition, and health. While in many LMICs, undernutrition and micronutrient deficiencies are still widespread, problems of overweight, obesity, and related non-communicable diseases are also massively on the rise. Supermarkets seem to contribute to overweight and obesity among adults, but effects on children and adolescents could possibly be different. Here, we review the available evidence about the implications of supermarkets for people's diets, nutrition, and health. Particular emphasis is placed on recent studies from urban Kenya that used panel data and differencing techniques to identify causal effects on different age cohorts. The results from Kenya show that shopping in supermarkets contributes to higher consumption of processed and highly processed foods and lower consumption of unprocessed foods. These dietary changes lead to significant increases in the body mass index and the probability of being overweight/obese and pre-diabetic among adults. For children, the same increases in overweight are not observed. Instead, supermarket shopping increases child height-for-age Z-scores. Despite higher food processing levels, supermarkets enhance food variety and dietary diversity in the relatively poor households. The results confirm that the growth of supermarkets affects adult and child nutrition differently; while the effects on adults are negative, the effects on children are positive, especially in the Kenyan context where child undernutrition is still widespread. Better understanding the effects of changing food environments on different age cohorts and in different contexts is important to design strategies that can help to make food choices in LMICs healthier. More research in different geographical settings will be useful.

Abstract
Behavioural weight management interventions in research studies and clinical practice differ in length, advice, frequency of meetings, staff, and cost. Few real-world programmes have published patient outcomes and those that have used different ways of reporting information, making it impossible to compare interventions and develop the evidence base. To address this issue, we have developed a core outcome set for behavioural weight management intervention programmes for adults with overweight and obesity. Outcomes were identified via systematic review of the literature. A representative expert group was formed comprising people with experience of adult weight management services. An online Delphi process was employed to reach consensus as to which outcomes should be measured and reported and which definitions/instruments should be utilised. The expert group identified eight core outcomes and 12 core processes for reporting by weight management services. Eleven outcomes and five processes were identified as optional. The most appropriate definitions/instruments for measuring each outcome/process were also agreed. Our core outcome set will ensure consistency of reporting. This will allow behavioural weight management interventions to be compared, revealing which interventions work best for which members of the population and helping inform development of adult behavioural weight management interventions.

Review of the Experience of Weight-Based Stigmatization in Romantic Relationships.
Côté, M, Bégin, C
Current obesity reports. 2020;(3):280-287
Abstract
PURPOSE OF REVIEW This narrative review summarizes literature on the stigma and prejudices experienced by individuals based on their weight in the context of romantic relationships. RECENT FINDINGS Individuals presenting with overweight or obesity, particularly women, are disadvantaged in the formation of romantic relationships compared with their normal-weight counterparts. They are also more prone to experience weight-based stigmatization towards their couple (from others), as well as among their couple (from their romantic partner). Currently available studies showed that weight-based stigmatization by a romantic partner was found to be associated with personal and interpersonal correlates, such as body dissatisfaction, relationship and sexual dissatisfaction, and disordered eating behaviors. Scientific literature on weight-based stigmatization among romantic relationships is still scarce. Prospective researches are clearly needed to identify consequences of this specific type of stigmatization on individuals' personal and interpersonal well-being. The use of dyadic designs could help to deepen our understanding as it would take into account the interdependence of both partners.

Can diet-induced weight loss improve iron homoeostasis in patients with obesity: A systematic review and meta-analysis.
Teng, IC, Tseng, SH, Aulia, B, Shih, CK, Bai, CH, Chang, JS
Obesity reviews : an official journal of the International Association for the Study of Obesity. 2020;(12):e13080
Abstract
Despite the increasing worldwide prevalence of obesity and iron deficiency (ID), there are still no guidelines on how to treat and manage obesity-related ID. The aim of this systematic review and meta-analysis was to investigate whether weight loss can re-establish iron homoeostasis among subjects with unhealthy weight (overweight [OW] or obesity). PubMed, Medline, Embase, Web of Science, and the Cochrane Library were systemically searched for studies that compared the iron status before and after a weight-loss intervention. A random-effects model was used to calculate the pooled and subgroup weighted mean differences (WMDs) of iron biomarkers. In total, 879 subjects were pooled across 14 studies. Improved haemoglobin was found in longitudinal studies (WMD = 2.50 g/dl, 95% confidence interval [CI]: 0.88, 4.12 g/dl, I2 = 14%) but not in randomized controlled trials or after being stratified by dietary programmes. Significantly increased transferrin saturation was observed in pooled (WMD = 1.68%, 95% CI: 0.97%, 2.39%, I2 = 44%) and subgroup analyses. A meta-regression showed that changes in the iron status were positively correlated with changes in the body mass index (BMI) and the intervention duration but negatively correlated with the baseline body weight/BMI, age, gender and a standard hypocaloric diet. Our data suggested that in spite of energy restrictions, weight loss may help re-establish iron homoeostasis in people who are OW or obese.

Implementation of WHO Recommended Policies and Interventions on Healthy Diet in the Countries of the Eastern Mediterranean Region: From Policy to Action.
Al-Jawaldeh, A, Hammerich, A, Doggui, R, Engesveen, K, Lang, K, McColl, K
Nutrients. 2020;(12)
Abstract
Non-communicable diseases (NCDs) are responsible for almost two-thirds of the deaths in the 22 countries and territories of the WHO Eastern Mediterranean Region and unhealthy diets are a major contributor. Prevalence of overweight and obesity has increased among adults, adolescents and older children in recent decades. Among countries with the highest prevalence there are signs that the increase is slowing down or even that prevalence is declining. There has been no increase in the prevalence rate in younger children, although the absolute number of children under five years affected by overweight has increased. This review summarizes prevalence data and examines current implementation of regulatory, fiscal and voluntary measures to promote healthy diet across the Region. The last decade has seen a step up in such action. Ten of the Region's countries have policies relating to trans-fatty acids and they are increasingly implementing specific regulatory measures. Thirteen countries had fully or partially implemented national salt reduction policies by 2019. Only four countries had adopted policies relating to aspects of marketing food to children by 2019, and concrete action in this area is still lacking. Eight countries have introduced taxes-sometimes at a rate of 50%-on carbonated or sugar-sweetened beverages. In order to meet the agreed global and regional goals relating to nutrition and diet-related NCDs, countries will need to build on this progress and scale up action across the Region while intensifying efforts in areas where concrete action is lacking.

Nutritional challenges in children and adolescents with Down syndrome.
Nordstrøm, M, Retterstøl, K, Hope, S, Kolset, SO
The Lancet. Child & adolescent health. 2020;(6):455-464
Abstract
Several features and comorbidities in Down syndrome have nutritional implications and consequences. In infancy and early childhood, children with Down syndrome have a high risk of oral motor difficulties and pharyngeal dysphagia with aspiration, which both require systematic attention. To improve nutritional status in children who are underweight and who have clinical signs of feeding problems, further evaluation of underlying causes is required. Clinical interventions should promote swallowing safety and development of feeding abilities. Even from 4-5 years of age, overweight in children with Down syndrome can be a concern. To prevent disease later in life, an urgent need exists for more research on nutritional aspects in the prevention and treatment of obesity in adolescents with Down syndrome. This Review did not find any data to support the use of dietary supplementation, except when deficiency is documented. Additionally, the literature reported the need for more research that uses larger study samples and control groups and that addresses important nutritional challenges in children and adolescents with Down syndrome.

Abstract
BACKGROUND Although there are many interventions targeting childhood obesity prevention, only few have demonstrated positive results. The current review aimed to gather and evaluate available school-based intervention studies with family involvement targeting dietary, physical activity and sedentary behaviors among primary schoolchildren and their families, in order to identify the most effective strategies. METHODS Studies published between 2000 and January 2015 were retrieved from scientific electronic databases and grey literature. The databases used included MEDLINE/PubMed, Web-of-Science, CINAHL and Scopus. Included studies had to be experimental controlled studies and had duration over 1 school year, had family involvement, combined PA and dietary behaviors and were implemented in school setting. A complementary search was executed to update the review to cover the period from February 2015 to January 2019. RESULTS From the studies examined (n = 425), 27 intervention programs (33 publications) fulfilled the inclusion criteria. Among these, 15 presented significant effect on weight status and/ or overweight/ obesity or clinical indices, 3 presented significant effect on most energy balance-related behaviors (EBRBs) while 9 presented significant effect on some/few EBRBs or determinants. Strategies implemented in effective interventions were: teachers acting as role-models and being actively involved in the delivery of the intervention, school policies supporting the availability of healthy food and beverage choices and limiting unhealthy snacks, changes in the schoolyard, in the recess rules and in the physical education classes to increase physical activity, and involving parents in the intervention via assignments, meetings, informative material and encouraging them to improve the home environment. Use of incentives for children, social marketing techniques, collaboration with local stakeholders were found to increase effectiveness. Programs that focused only on educational sessions and material for parents, without promoting relevant environmental and policy changes, were found to be less effective. Cultural adaptations have been suggested to increase the intervention's acceptance in specific or vulnerable population groups. CONCLUSIONS Several effective strategies were identified in the reviewed programs. Outcomes of the current review were taken into account in developing the Feel4Diabetes-intervention and summed up as recommendations in the current work in order to facilitate other researchers designing similar childhood obesity prevention initiatives.

What Model of Nutrition Can Be Recommended to People Ending Their Professional Sports Career? An Analysis of the Mediterranean Diet and the CRON Diet in the Context of Former Athletes.
Hołowko-Ziółek, J, Cięszczyk, P, Biliński, J, Basak, GW, Stachowska, E
Nutrients. 2020;(12)
Abstract
Athletes who retire from their sporting career face an increase in body weight, leading to overweight or obesity. Simultaneously, a significant number of these athletes meet the criteria of metabolic syndrome. The available literature does not offer clearly defined standards of nutrition for the discussed group of people. In this situation, it seems advisable to develop different standards of dietary behavior typical of athletes finishing their sports careers. For this purpose, the study analyzed two types of diets: the Mediterranean diet and the Calorie Restriction with Optimal Nutrition (CRON) diet based on significant calorie restrictions. Both diets seem to meet the requirements of this group of people.

Obesity, the new childhood disability? An umbrella review on the association between adiposity and physical function.
Tsiros, MD, Tian, EJ, Shultz, SP, Olds, T, Hills, AP, Duff, J, Kumar, S
Obesity reviews : an official journal of the International Association for the Study of Obesity. 2020;(12):e13121
Abstract
The adverse physical impacts of childhood obesity are increasingly being recognized. The objective of this study is to examine relationships between physical function and adiposity in youth. An umbrella review searched seven databases from inception to May 2019 for systematic reviews examining associations between adiposity and physical function in 0-20-year-olds. Findings were synthesized using the International Classification of Functioning, Disability and Health Framework and NHMRC FORM. Seventeen of 21 systematic reviews reported impairments to body function, including cardiorespiratory fitness (CRF), muscle function, balance/coordination, gait biomechanics, pain and injury. Six reviews reported activity restrictions in motor skills, running speed/agility and functional mobility, and two found inverse associations between adiposity and physical health-related quality of life (p-HRQOL). Some causal relationships indicated that adiposity inversely predicted p-HRQOL/CRF and CRF/muscle function inversely predicted adiposity. Assessments of physical function were heterogeneous and impacts on participation in life situations meaningful to the individual were largely unknown. Substantial evidence associates childhood overweight/obesity with reduced physical function. Associations were mainly cross-sectional, with causative evidence for some outcomes. Comprehensive physical function assessments by qualified health professionals are needed, along with targeted interventions to address deficits. Research should further examine causality of relationships, underlying mechanisms and participation challenges in real-life contexts.
