Plain language summary
Childhood obesity is a major public health issue across the world. The incidence of skipping breakfast among children and adolescent is rising. Numerous studies have shown a positive relationship between skipping breakfast and overweight or obesity. The aim of the study was to analyse the association of skipping breakfast with body weight and metabolic outcomes in the paediatric population. The study is a systemic review focusing on studies published in the last ten years. 39 articles were included for analysis and data from a total of 286,804 children and adolescents were reported. The systemic review demonstrates that children and adolescents who skip breakfast are at higher risk to be or become overweight or obese. Authors conclude that skipping breakfast may be a potential marker of lifestyle behaviours in children and adolescents that promote overweight or obesity and metabolic diseases.
Abstract
The incidence of skipping breakfast in pediatric subjects is rising, and a relationship with overweight (OW) and obesity (OB) has been shown. Associations with cardiovascular outcomes and skipping breakfast in adults have been reported. The purpose of this systematic review was to summarize the association of skipping breakfast with body weight and metabolic outcomes in the pediatric population. We searched relevant databases (2008⁻2018) and identified 56 articles, of which 39 were suitable to be included, basing on inclusion criteria (observational; defined breakfast skipping; weight and/or metabolic outcomes). Overall, 286,804 children and adolescents living in 33 countries were included. The definitions of OW/OB, skipping breakfast, and the nutrient assessment were highly heterogeneous. Confounding factors were reported infrequently. The prevalence of skipping breakfast ranged 10⁻30%, with an increasing trend in adolescents, mainly in girls. Skipping breakfast was associated with OW/OB in the 94.7% of the subjects. The lack of association was shown mainly in infants. Moreover, 16,130 subjects were investigated for cardiometabolic outcomes. Skipping breakfast was associated with a worse lipid profile, blood pressure levels, insulin-resistance, and metabolic syndrome. Five studies reported a lower quality dietary intake in breakfast skippers. This review supports skipping breakfast as an easy marker of the risk of OW/OB and metabolic diseases, whether or not it is directly involved in causality. We encourage intervention studies using standardized and generalizable indicators. Data on confounders, time of fasting, chronotypes, and nutrition quality are needed to establish the best practice for using it as a tool for assessing obesity risk.

Plain language summary
Metabolic syndrome (MetS) is a complex disease characterised by high blood sugar, raised blood pressure, dyslipidemia and obesity. It is a major contributing factor to chronic disease such as type 2 diabetes and cardiovascular disease. The aim of this study is to review the cause of MetS, understand how it progresses to chronic disease and analyse the efficacy of clinical interventions in reducing this progression. According to the existing research, this study found insulin sensitivity to be a critical aspect of the pathogenesis in MetS. Effective intervention strategies should be aimed at increasing insulin sensitivity. Based on this information, the authors conclude health practitioners should help patients manage energy balance and reduce overall inflammatory markers to best control the progression of MetS.
Abstract
The growing prevalence of metabolic syndrome (MetS) in the U.S. and even worldwide is becoming a serious health problem and economic burden. MetS has become a crucial risk factor for the development of type 2 diabetes mellitus (T2D) and cardiovascular diseases (CVD). The rising rates of CVD and diabetes, which are the two leading causes of death, simultaneously exist. To prevent the progression of MetS to diabetes and CVD, we have to understand how MetS occurs and how it progresses. Too many causative factors interact with each other, making the investigation and treatment of metabolic syndrome a very complex issue. Recently, a number of studies were conducted to investigate mechanisms and interventions of MetS, from different aspects. In this review, the proposed and demonstrated mechanisms of MetS pathogenesis are discussed and summarized. More importantly, different interventions are discussed, so that health practitioners can have a better understanding of the most recent research progress and have available references for their daily practice.
