The aims of this study was to determine the cutoff values for tri-ponderal mass index (TMI) and investigate the association between overweight/obesity as classified by TMI and cardiometabolic risk factors in Brazilian adolescents aged 12 to 17 y. ⋯ Obesity, as classified by TMI, was strongly associated with several cardiovascular risk factors. Our data showed that TMI was stable across the age span. Therefore, a fixed cutoff value to determine weight status in Brazilian adolescents seems appropriate.

Globally, the prevalence of overweight and obesity, including among pregnant women, has substantially increased in the past three decades. This has been fueled by, among other factors, an increase in the consumption of high energy-dense foods and a decrease in physical activity. Additionally, global prevalence of anemia among pregnant women remains a public health concern. ⋯ Yet current knowledge in this field, including prevalence rates, risk factors, and health consequences for mother and offspring being exposed to these conditions, is staggeringly sparse. In this review we describe the current evidence on prevalence rates, risk factors, and effects for mother and offspring regarding coexistence of overweight/obesity and anaemia in pregnant women based on a systematic literature search. We also highlight research gaps and suggest avenues for future research.

Overnutrition is a poor dietary habit that has been correlated with increased health risks, especially in the developed world. This leads to an imbalance between energy storage and energy breakdown. Many biochemical processes involving hormones are involved in conveying the excess of energy into pathologic states, mainly atherosclerosis, hypertension, cardiovascular diseases, and diabetes. ⋯ In parallel, important effects of diets on the immune system are explored as essential components that can undermine the overall health outcome. Additionally, the subtle but relevant relation between diet and sleep is investigated for its impact on the cardiovascular system and quality of life. The aim of this review is to focus on how calorie restriction triggers multiple molecular pathways that ultimately lead to hormetic effects resulting in cell longevity and resistance to cardiovascular disease, stroke, and cancer.

Randomized Controlled Trial
Maternal diets have effects on intestinal mucosal flora and susceptibility to colitis of offspring mice during early life.
Intestinal flora is considered closely related to the occurrence of inflammatory bowel disease (IBD). This study aimed to discover whether diverse diet conditions during early life lead to different intestinal flora structure and impact different susceptibility to IBD. ⋯ In general, our study shows that a maternal high-protein diet during early life can negatively regulate the intestinal flora diversity of offspring mice. A high-protein diet during early life led to higher susceptibility of IBD in offspring rats.

Type 2 diabetes control occurs within a few days after Roux-en-Y gastric bypass (RYGB) and might be related to intestinal adaptation to the new anatomic arrangement. The aim of this study was to evaluate the intestinal transcriptome response to RYGB and its correlation with markers of glycemic homeostasis. ⋯ In obese women, complete remission of T2D after RYGB might include intestinal transcriptomic changes that suggest a potential role of intracellular cholesterol and lipid homeostasis on glucose control.
