Murdoch Childrens Research Institute via EurekAlert! – Obesity rates are set to skyrocket, with one in six children and adolescents worldwide forecast to be obese by 2050, according to a new study. But with significant increases predicted within the next five years, the researchers stress urgent action now could turn the tide on the public health crisis. The research, led by Murdoch Children’s Research Institute (MCRI) and published in The Lancet, found a third of children and adolescents will be overweight (385 million) or obese (360 million) within the next 25 years. The forecast equates to 356 million children aged 5–14 years and 390 million aged 15–24 years with one in six facing obesity. The global obesity rate for those between 5-24 years old tripled from 1990 to 2021, rising by 244 per cent to 174 million, suggesting that current approaches to curbing increases in obesity have failed a generation of young people. As of 2021, 493 million children and adolescents were overweight or obese. MCRI Dr Jessica Kerr said if immediate five-year action plans were not developed, the future was bleak for our youth. “Children and adolescents remain a vulnerable population within the obesity epidemic,” she said. Prevention is key as obesity rarely resolves after adolescence. “This giant burden will not only cost the health system and the economy billions, but complications associated with a high Body Mass Index (BMI), including diabetes, cancer, heart problems, breathing issues, fertility problems and mental health challenge, will negatively impact our children and adolescents now and into the future, even holding the potential to impact our grandchildren’s risk of obesity and quality of life for decades to come. “Despite these findings indicating monumental societal failures and a lack of coordinated global action across the entire developmental window to reduce obesity, our results provide optimism that this trajectory can be avoided if action comes before 2030.” The analysis, released on World Obesity Day, used the 2021 Global Burden of Diseases, Injuries, and Risk Factors Study led by the Institute for Health Metrics and Evaluation to estimate the latest overweight and obesity levels and forecasts in 204 countries and territories. The United Arab Emirates, Cook Islands, Nauru and Tonga are forecast to have the highest prevalence while China, Egypt, India and the US will have the greatest number of children and adolescents with obesity by 2050. In Australia, children and adolescents have experienced some of the fastest transitions to obesity in the world. Girls are already more likely to be obese than overweight. Overall, by 2050 for those aged 5-24 years, 2.2 million are forecasted to be obese and 1.6 million overweight. Globally, there will be more boys, 5–14 years, with obesity than being overweight by 2050. “Without urgent policy reform, the transition to obesity will be particularly rapid in north Africa, the Middle East, Latin America and in the Caribbean, where the rise is concurrent with high population numbers and limited resources,” Dr Kerr said. “Many regions have historically had to focus on preventing undernutrition and stunting in children. To prevent a public health emergency from this newer threat, an immediate imperative should be creating national surveillance surveys of obesity in children and adolescents in every country.” Dr Kerr said older adolescent girls, aged 15-24 years entering their reproductive years, were a priority population for intervention. “Adolescent girls who are obese are a main focus if we are to avoid intergenerational transmission of obesity, chronic conditions and the dire financial and societal costs across future generations,” she said. “With this age group increasingly being out of school and cared for by adult services, we need to focus interventions at the community and commercial level.” MCRI Professor Susan Sawyer said governments needed to invest in multicomponent strategies that reduce obesity drivers, across food and drink, activity, lifestyle and the built environment. “While people and families can work to balance their physical activity, diet and sleep, everything in our environments works to counteract these efforts,” she said. “Given this huge global shift in children’s and adolescents’ weight, we can no longer keep blaming people for their choices. We require governments to step up by addressing regulatory interventions including taxing sugar sweetened beverages, banning junk food advertising aimed at children and young people and funding healthy meals in primary and secondary schools. We also need to consider the benefits of wider policies such as overhauling urban planning to encourage active lifestyles.” Publication: ‘Global, regional, and national prevalence of child and adolescent overweight and obesity, 1990-2021, with forecasts to 2050: a forecasting study for the Global Burden of Disease Study 2021,’ The Lancet. *The content of this communication is the sole responsibility of MCRI and does not reflect the views of the NHMRC.

Weight Loss Surgery Undergone Before Pregnancy May Influence Children’s Weight Gain

The AHA! Team — Thu, 05 Sep 2024 08:29:54 +0000

The Endocrine Society via EurekAlert! – BOSTON—The type of weight loss surgery women undergo before becoming pregnant may affect how much weight their children gain in the first three years of life, suggests a study being presented Monday at ENDO 2024, the Endocrine Society’s annual meeting in Boston, Mass. Researchers found children born to women who underwent the bariatric procedure known as sleeve gastrectomy before they became pregnant gain more weight per month on average in the first three years of life compared with children born to women who had the less common Roux-en-Y gastric bypass weight loss procedure. “Either the extent of pre-pregnancy weight loss or the metabolic changes from Roux-en-Y gastric bypass may be favorable for the children’s early childhood weight gain,” said researcher Vidhu Thaker, M.D., of the Columbia University Irving Medical Center in New York, N.Y. Maternal obesity is a risk factor for obesity in children. Women are more likely to conceive following weight loss procedures, but less is known about the early growth of the children born after pre-pregnancy weight loss procedures. Sleeve gastrectomy and Roux-en-Y gastric bypass are two of the more common types of weight loss surgery, also known as bariatric and metabolic surgery. These surgeries result in sustained weight loss and improve the body’s metabolism in the majority of patients. In vertical sleeve gastrectomy (also called gastric sleeve surgery), a surgeon removes most of the stomach, leaving only a banana-shaped section that is closed with staples. By removing a part of the stomach that makes hormones that drive hunger, this procedure also decreases appetite. In gastric bypass, the surgeon divides the stomach into two parts, sealing off the upper section from the lower. The surgeon then connects the upper stomach directly to the lower section of the small intestine. This creates a shortcut for food, bypassing part of the stomach and the small intestine. Skipping these parts of the digestive tract means the body absorbs fewer calories and nutrients. The researchers examined the weight and length of offspring born after pre-pregnancy weight loss procedures in the first three years of life. The study used data from 20,515 deliveries over three years, of which 450 had pre-pregnancy weight loss procedures. Among the mothers who underwent weight loss surgery, 57% had sleeve gastrectomy and 41% had Roux-en-Y gastric bypass. Long-term weight and length data were available for about half of the babies in each group. The researchers found there was no difference in birth weight among the babies born after weight loss surgery. The pace of weight gain was higher in those born after pre-pregnancy sleeve gastrectomy compared to those born following Roux-en-Y gastric bypass, while adjusting for several other variables including pre-pregnancy body mass index. “While we did not have data on the magnitude of weight loss following bariatric surgery, Roux-en-Y gastric bypass is known to have higher weight loss and metabolic changes compared to sleeve gastrectomy,” Thaker noted. The authors concluded that the either the extent of pre-pregnancy weight loss or the metabolic changes from Roux-en-Y gastric bypass may be favorable for the offspring’s early childhood weight trajectory. “A study of the mechanisms underlying the associations of the sustained pre-pregnancy weight loss and the offspring’s early life growth may also apply to other methods of weight loss, including the most recently approved anti-obesity medications,” Thaker said. # # # Endocrinologists are at the core of solving the most pressing health problems of our time, from diabetes and obesity to infertility, bone health, and hormone-related cancers.

Gut Microbiota Influences the Ability to Lose Weight

AHA Publisher — Fri, 17 Sep 2021 07:00:21 +0000

American Society for Microbiology (ASM) via Newswise – Washington, D.C. – September 14, 2021 – Gut microbiota influences the ability to lose weight in humans, according to new research. The findings were published this week in mSystems, an open-access journal of the American Society for Microbiology. “Your gut microbiome can help or cause resistance to weight loss and this opens up the possibility to try to alter the gut microbiome to impact weight loss,” said lead study author Christian Diener, Ph.D., a research scientist at the Institute for Systems Biology in Seattle, Washington. To conduct their research, Dr. Diener and colleagues focused on a large cohort of individuals who were involved in a lifestyle intervention study. Instead of a specific diet or exercise program, this intervention involved a commercial behavioral coaching program paired with advice from a dietician and nurse coach. The researchers focused on 48 individuals who lost more than 1% of their body weight per month over a 6 to 12 month period and 57 individuals who did not lose any weight and had a stable body mass index (BMI) over the same period. The researchers relied on metagenomics, the study of genetic material recovered from blood and stool samples. The individuals analyzed blood metabolites, blood proteins, clinical labs, dietary questionnaires and gut bacteria in the two groups. After controlling for age, sex and baseline BMI, the researchers identified 31 baseline stool metagenomic functional features that were associated with weight loss responses. These included complex polysaccharide and protein degradation genes, stress-response genes, respiration-related genes, cell wall synthesis genes and gut bacterial replication rates. A major finding was that the ability of the gut microbiome to break down starches was increased in people who did not lose weight. Another key finding was that genes that help bacteria grow faster, multiply, replicate and assemble cell walls were increased in people who lost more weight. “Before this study, we knew the composition of bacteria in the gut were different in obese people than in people who were non-obese, but now we have seen that there are a different set of genes that are encoded in the bacteria in our gut that also responds to weight loss interventions,” said Dr. Diener. “The gut microbiome is a major player in modulating whether a weight loss intervention will have success or not. The factors that dictate obesity versus nonobesity are not the same factors that dictate whether you will lose weight on a lifestyle intervention.” Research has already shown that if you change your diet, you can alter the composition of bacteria in your gut. According to Dr. Diener, if someone has a composition of gut bacterial genes that confers resistance to weight loss, then perhaps you can alter their diet to shift to a composition that would help them lose weight.
