“…Concerningly, some countries report increasing rates of the highest BMI groups growing for children and adolescents, with potential for excess weight to track through into adulthood. This would differ from current patterns, when rates are lower in early adulthood, peaking in middle age . Unusually, the survey data from Brunei Darussalam showed 19‐ to 29‐year‐olds having some of the highest rates of BMI ≥40 across the age trajectory…”

Rising prevalence of BMI ≥40 kg/m²: A high‐demand epidemic needing better documentation

Summary Whilst previously rare, some surveys indicate substantial increases in the population with body mass index (BMI) ≥40 kg/m2 since the 1980s. Clinicians report emerging care challenges for this population, often with high resource demands. Accurate prevalence data, gathered using reliable methods, are needed to inform health care practice, planning, and research. We searched digitally for English language sources with measured prevalence data on adult BMI ≥40 collected since 2010. The search strategy included sources identified from recent work by NCD‐RisC (2017), grey sources, a literature search to find current sources, and digital snowball searching. Eighteen countries, across five continents, reported BMI ≥40 prevalence data in surveys since 2010: 12% of eligible national surveys examined. Prevalence of BMI ≥40 ranged from 1.3% (Spain) to 7.7% (USA) for all adults, 0.7% (Serbia) to 5.6% (USA) for men, and 1.8% (Poland) to 9.7% (USA) for women. Limited trend data covering recent decades support significant growth of BMI ≥40 population. Methodological limitations include small samples and data collection methods likely to exclude people with very high BMIs. BMI ≥40 data are not routinely reported in international surveys. Lack of data impairs surveillance of population trends, understanding of causation, and societal provision for individuals living with higher weights.

“…There is limited literature on the prevalence and characteristics of RH in overweight and obese patients, with one report estimating a prevalence of apparent treatment‐resistant hypertension (ATRH), defined as RH detected at the office, in obese patients of around 14% based on the BP cutoff of ≥140/90 mm Hg to diagnose hypertension . The effect of obesity on RH and BP control has become an important topic recently, especially with the global increase in the prevalence of both diseases over the past few decades . To our knowledge, there are no studies that evaluated RH in this population based on the new hypertension definition with BP cutoff of ≥130/80 mm Hg to diagnose the condition.…”

Obesity is significantly associated with uncontrolled blood pressure and resistant hypertension (RH). There are limited studies on the prevalence and determinants of RH in patients with higher body mass index (BMI) values. Since the hypertension guidelines changed in 2017, the prevalence of RH has become unknown and now is subject to be estimated by further studies. We conducted a cross‐sectional study in an urban Federally Qualified Health Center in New York City aiming to estimate the prevalence of RH in high‐risk overweight and obese patients based on the new hypertension definition, BP threshold ≥130/80 mm Hg, and also to describe the associated comorbid conditions in these patients. We identified 761 eligible high‐risk overweight and obese subjects with hypertension between October 2017 and October 2018. Apparent treatment‐RH was found in 13.6% among the entire study population. This represented 15.4% of those treated with BP‐lowering agents. True RH confirmed with out‐of‐office elevated BP was found in 6.7% of the study population and 7.4% among patients treated with BP‐lowering agents. Prevalence was higher with higher BMI values. Those with true RH were more likely to be black, to have diabetes mellitus requiring insulin, chronic kidney disease stage 3 or above and diastolic heart failure. In conclusion, obesity is significantly associated with RH and other significant metabolic comorbid conditions.

“…Obesity presents a pressing public health challenge , with 40% of adults in the United States with obesity and another third with overweight . Although a healthy diet is key to obesity treatment and prevention, weight‐loss trials that incorporate dietary changes have mixed success, with variation in participants’ levels of treatment engagement, dietary adherence, and weight outcomes .…”

Objective The purpose of this study was to examine correlates of failure—trial attrition and weight gain—in a randomized clinical weight‐loss trial. Methods The Diet Intervention Examining The Factors Interacting with Treatment Success (DIETFITS) trial included 609 adults (18‐50 years; BMI 28‐40). Participants were randomized to a 12‐month healthy low‐fat or healthy low‐carbohydrate diet for weight loss. At baseline, participants completed psychosocial, demographic, and anthropometric measures. Stepwise logistic regressions identified baseline factors associated with (1) study attrition and (2) among trial completers, weight gain at 12 months. Results Having higher baseline food addiction and self‐efficacy was linked to treatment failure. Being younger, not having a college education, having higher outcome expectations and quality of life, and having lower social functioning and self‐control increased the odds of trial attrition. Identifying as other than non‐Hispanic white; not being married or cohabitating; having higher cognitive restraint and self‐control; and having lower amotivation, family encouragement, and physical limitations increased the odds of gaining weight by treatment’s end. Conclusions Participants’ baseline psychosocial and demographic factors may support or impede successful weight loss. Trialists should attend to these factors when designing treatments in order to promote participants’ likelihood of completing the trial and achieving their weight‐loss goals.
