[Physical activity in preventing metabolic syndrome in children]

Metabolic syndrome therapy in pediatric age - between classic and modern. From diets to pipeline drugs

The metabolic syndrome, made up of the sum of the entities that define it (obesity, hypertension, dyslipidemias and non-alcoholic hepatic steatosis) has gained an important place in the research of the last decades. This aspect is mainly due to the complexity of management in pediatric practice. The main directions in his approach therefore bring together the concern of counteracting the noise or systemic, of the multiple intercurrents at the physiopathological level, as well as the negative imprint exerted on the quality of life. Its appearance and evolution are currently controversial topics, but the influence of genetic predisposition and lifestyle (diet, physical activity, psychological balance) are certainties. Considering the escalation of the incident at the global level, it is self-evident that it is necessary to know the pathogenesis and practice countermeasures for prophylactic or therapeutic purposes. The present work aims to summarize general aspects related to the metabolic syndrome encountered in pediatric age, with an emphasis on complementary therapeutic perspectives and their effectiveness, by analyzing the latest data from the specialized literature, accessed with the help of international databases (e.g., PubMed, Web of Science, Scopus, Embase, Google Scholar).

The need for dialysis in Haiti: dream or reality?

According to the World Health Organization reports, nowadays burden of chronic kidney diseases (CKD) is well documented. The high prevalence of noncommunicable diseases (NCD) such as hypertension, diabetes, and obesity, which are the main causes of CKD, is a big concern in the world health scenario. These NCD can progress slowly to end-stage renal disease (ESRD) and the low-middle income countries (LMIC) like Haiti are not left unscathed by this worldwide scourge. Several well-known public health issues prevalent in Haiti such as acute diarrheal infections, malaria, tuberculosis, cholera, and acquired immunodeficiency syndrome (AIDS), can also impair the function of the kidney. Dialysis, a form of renal replacement therapy (RRT), represents a life-saving therapy for all patients affected with impaired kidney. In Haiti, few patients have access to health insurance or disability financial support. Considering that seventy-two percent (72%) of Haitians live with less than USD 2 per day, survival with CKD can be quite stressful for them. Data on the weight of the dialysis and its management are scarce. Addressing the need for dialysis in Haiti is an important component in decision-making and planning processes in the health sector. This paper is intended to bring forth discussion on the use of this type of renal replacement therapy in Haiti: the past, the present, and the challenges it presents. We will also make some recommendations in order to manage this serious problem.

Childhood obesity and walking: guidelines and challenges

The development and maintenance of excess body mass in many children is partly attributable to levels of physical activity that are lower than the recommended 60 minutes/day. Walking is a recommended form of physical activity for obese children, due to its convenience and perceived ease of adoption. Unfortunately, studies that have used objective physical activity assessment continue to report low step counts and levels of physical activity in obese children. This may be due to physiological and/or biomechanical factors that make walking more difficult for obese children. The purpose of this review is to highlight the current recommended and measured levels of physical activity for children and to discuss the physiological and biomechanical challenges of walking for obese children that may help explain why these children are not meeting physical activity goals.

Insight into physical activity in combating the infantile metabolic syndrome

Metabolic syndrome (MetS) is increasingly reported in children, mainly in the presence of overweight/obesity. From the most recent report, up to 60% of overweight and obese children can be affected by this syndrome. MetS acquired during childhood has been shown to track into adulthood, including its clinical complications, such as type 2 diabetes and cardiovascular diseases. Among the practical preventive and therapeutic measures to be taken in children, physical activity (PA) appears to be at least as efficient as the most adequate pharmacology. The current literature suggests that exercise programs based either on aerobic-or resistance-type exercises, or a combination of these 2 types of structured activity, may promote insulin sensitivity and weaken or suppress MetS in children. Furthermore, daily-living activities such as brisk walking were found to substantially reduce the risk of MetS among children. Regardless of their weight status, PA needs to be promoted among children as early as possible.
