This overview of reviews aimed to summarize the effects of exercise training programs on weight loss, changes in body composition, and weight maintenance in adults with overweight or obesity. A systematic search of systematic reviews and metaanalyses (SR-MAs) published between 2010 and December 2019 was performed. Only SR-MAs of controlled trials were included. The mean difference (MD) or standardized MD (SMD) were extracted from SR-MAs. Twelve SR-MAs (149 studies) were included. Exercise led to a significant weight loss (4 SR-MAs, MDs ranging from −1.5 to −3.5 kg), fat loss (4 SR-MAs, MDs ranging from −1.3 to −2.6 kg) and visceral fat loss (3 SR-MAs, SMDs ranging from −0.33 to −0.56). No difference in weight, fat, and visceral loss was found between aerobic and high-intensity interval training as

We aimed to assess the effectiveness of exercise training programs in adults with severe obesity undergoing bariatric surgery. A systematic search of controlled trials published up to October 2019 that assigned participants to either a preoperative or postoperative exercise training group or a nonexercise group was performed.Meta-analyses were conducted using random-effects models. Twenty-two training programs were assessed (18 performed after bariatric surgery). The effect of preoperative exercise training on postsurgery outcomes was reported in only one study.

There is a need for updated practice recommendations on exercise in the management of overweight and obesity in adults. We summarize the evidence provided by a series of seven systematic literature reviews performed by a group of experts from across Europe. The following recommendations with highest strength (Grade A) were derived. For loss in body weight, total fat, visceral fat, intra-hepatic fat, and for improvement in blood pressure, an exercise training program based on aerobic exercise at moderate intensity is preferentially advised. Expected weight loss is however on average not more than 2 to 3 kg. For preservation of lean mass during weight loss, PROSPERO registration number: CRD42019157823.

The prevalence of dental decay is expected to rise in many developing countries due to the growing consumption of sugars. This study aimed to assess knowledge, attitudes and practices of sweet food and beverage consumption among schoolchildren in Jazan, Saudi Arabia and to determine the relationship with dental caries. In a cross-sectional, descriptive study 853 children aged 6-15 years (520 boys and 333 girls) were assessed by questionnaire and clinical examinations. Caries prevalence (≥ 1 dft/DMFT) was high (91.3%). While knowledge was generally good, 83.5% boys and 85.8% girls had poor attitudes to sweet foods and > 90% frequently consumed sweet foods/beverages. Multiple regression analysis showed that children whose mothers were less educated (OR 2.46; 95% CI: 1.15-5.28) and children with poor dietary attitudes and practices (OR 4.05; 95% CI: 2.33-7.03 and OR 7.80; 95% CI: 4.50-13.52 respectively) were more likely to have dental caries. Well-directed health promotion programmes are needed in Jazan. ,03 et OR 7,80 ; IC à 95 % : 4,50-13,52 respectivement) étaient plus à risque de présenter des caries dentaires. Des programmes de promotion de la santé convenablement ciblés sont nécessaires à Jazan. ‫ـنان‬

Background: Nutrition education is one method to change the knowledge and attittude of nutrition on school children.The study aimed to see the effect of nutrition education on knowledge and attitude of nutrition among school children.Methods: The study was one group pre-post test design of a quasi experimental design. Subjects were 99 schoolchildren randomly selected through multi stage sampling method among the 4th, 5th, and 6th graders. They were givennutrition education using posters and pocket books in children meeting for three months. The data of knowledge andattitude were collected through interview using structure questionares. The differences in knowledge attitude andpractice of of nutrition among school children were tested by wilcoxon test.Results: The mean of knowledge about nutrition among school children before nutrition education is 66,45±9,6%increasing to 71,61±9,3% after nutrition education. Median of attitude before nutrition education is 70,31% increasingto 75% after nutrition education. The result showed that there was an effect of nutrition education on knowledge andattitude of school children.Conclusion: Nutrition education can improve knowledge and attitude of school children.
