Plain language summary
Infants and children are consuming increasing amounts of foods with added sugars, high in salt, and high in saturated or trans fats. Commercially prepared foods are more likely to be high in energy, low in nutrients (energy dense, nutrient-poor), and ultra-processed. The aim of this study was to examine, in children aged ≤10.9 y, the risks of greater consumption of unhealthy foods and beverages compared with no or low consumption on overweight and obesity. This study is a systematic review and meta-analysis which included the summarized characterises of 71 articles from 60 included studies. Results indicate that in children aged ≤10.9 years, consumption of sugar-sweetened beverages and unhealthy foods may increase body mass index, percentage body fat, or the odds of overweight/obesity (low to very-low certainty). Furthermore, there was little or no difference to body mass index, percentage body fat, or overweight/obesity outcomes (low certainty) after consumption of artificially sweetened beverages and 100% fruit juices. Authors conclude that policy recommendations are needed to address the growing burden of overweight and obesity that children are experiencing worldwide.
Abstract
This WHO-commissioned review contributed to the update of complementary feeding recommendations, synthesizing evidence on effects of unhealthy food and beverage consumption in children on overweight and obesity. We searched PubMed (Medline), Cochrane CENTRAL and Embase for articles, irrespective of language or geography. Inclusion criteria were: 1) randomized controlled trials (RCTs); non-RCTs; cohort studies and pre/post studies with control; 2) participants ≤ 10.9 y at exposure; 3) studies reporting greater consumption of unhealthy foods/beverages vs. no or low consumption; 4) studies assessing anthropometric and/or body composition; and 5) publication date ≥ 1971. Unhealthy foods and beverages were defined using nutrient- and food-based approaches. Risk of bias was assessed using the ROBINS-I and RoB2 tools for non-randomized and randomized studies, respectively. Narrative synthesis was complemented by meta-analyses where appropriate. Certainty of evidence was assessed using GRADE. Of 26,542 identified citations, 60 studies from 71 articles were included. Most studies were observational (59/60), and no included studies were from low-income countries. The evidence base was low quality, as assessed by ROBINS-I and RoB2 tools. Evidence synthesis was limited by the different interventions and comparators across studies. Evidence indicated that consumption of sugar-sweetened beverages (SSB) and unhealthy foods in childhood may increase body mass index (BMI)/BMI z-score, % body fat or odds of overweight/obesity (low certainty of evidence). Artificially-sweetened beverages and 100% fruit juice consumption may make little/no difference to BMI, % body fat or overweight/obesity outcomes (low certainty of evidence). Meta-analyses of a subset of studies indicated a positive association between SSB intake and % body fat, but no association with change in BMI and BMI z-score. High-quality epidemiological studies that are designed to assess the effects of unhealthy food consumption during childhood on risk of overweight/obesity are needed to contribute to a more robust evidence base upon which to design policy recommendations.

Plain language summary
It has been recognised that mechanisms to cope with stress and the inability to feel pleasure can include eating foods high in sugar, carbohydrates, and fat, resulting in obesity. The current Covid-19 pandemic could be causing stress and anxiety to many individuals. This cross-sectional study aimed to determine the role of anxiety and reduced feelings of pleasure on diet and weight during the covid-19 pandemic in 1725 individuals in Chile. The results showed that anxiety levels were related to an increased consumption of sugar-sweetened drinks, fast food, and pastries. However, there was no relationship between lockdown measures due to Covid-19 and feelings of anxiety or reduced feelings of pleasure. Increased portion sizes were also related to anxiety levels. It was concluded that high levels of anxiety were related to increased consumption of unhealthy foods. This study could be used by healthcare professionals to recognise the need to recommend healthy eating habits for the wellbeing of patients who are suffering from anxiety.
Abstract
The current epidemic of COVID-19 has gained attention and highlighted the need for a better understanding of the population's mental health. Diet has been identified as an environmental determinant of mental health. In this regard, it has been suggested that the consumption of palatable foods represents a strategy to mitigate negative emotions, such as anxiety. This study aimed to evaluate the association between symptoms of anxiety and/or anhedonia to food consumption patterns during the period of COVID-19 quarantine in Chile. We conducted a cross-sectional study with non-randomized sampling via an online survey. A total of 1725 responses were collected. Each person self-answered the Beck Anxiety Inventory, Snaith-Hamilton Pleasure Scale for anhedonia, the Food Intake Questionnaire, and questions regarding type and duration of lockdown, as well as body weight and food serving variation. Significant correlations were observed between fried food consumption and self-reported body weight. The subjects who consumed fried food three times a week, had higher weight (63.5%) (χ2 = 48.5 and p < 0.001). Those who ate one and two or more pastries on a week had 1.41 and 1.49, respectively higher odds of reporting increased body weight. We found a relationship anxiety level and sugar-sweetened beverages level (χ2 = 25.5; p 0.013), fast food intake (χ2 = 63.4; p < 0.001), and pastry consumption (χ2 = 37.7; p < 0.001). In conclusion, it is important to monitor the evolution of these findings since they could represent a risk of increased health problems in the future post-lockdown period.
