New investigation being presented astatine this year's European Congress connected Obesity (ECO) successful Venice, Italy (12-15 May), identifies nan optimum assemblage weight scope for adults pinch type 2 glucosuria to minimize their consequence of dying from immoderate cardiovascular disease, including bosom failure, bosom disease, stroke, and chronic kidney disease.

The findings, based connected wellness information from nan UK Biobank, bespeak that for adults aged 65 years aliases younger, maintaining a assemblage wide scale (BMI) wrong nan normal scope of 23–25 kg/m² was associated pinch nan lowest consequence of dying from cardiovascular disease. But for those complete 65 years old, being moderately overweight pinch a BMI of 26–28 kg/m², had nan lowest risk.

Maintaining a patient weight is important for reducing nan consequence of cardiovascular diseases, peculiarly for people pinch type 2 diabetes who are predisposed to cardiovascular illness and death. However, it's not clear whether nan optimal BMI scope for group pinch type 2 glucosuria varies by age.

To plug these knowledge gaps, researchers explored nan property differences successful nan relation betwixt BMI and consequence of cardiovascular decease successful 22,874 UK Biobank participants pinch a erstwhile test of type 2 glucosuria astatine nan clip they enrolled betwixt 2006 and 2010. Patients pinch anterior cardiovascular diseases were not excluded.

The mean property of each nan participants was 59 years, and astir 59% were women. Their cardiovascular wellness was tracked, utilizing linked wellness records, for astir 13 years during which clip 891 participants died from cardiovascular diseases.

Researchers analyzed information successful 2 property groups-;the aged (over 65 years) and nan middle-aged (age 65 years aliases younger)-;and assessed nan narration betwixt variables specified arsenic BMI, waist circumference, and waist-to-height ratio and nan consequence of cardiovascular death.

The optimal BMI cut-off constituent was besides calculated successful different property groups and nan findings were adjusted for accepted cardiometabolic consequence factors and different factors associated pinch adverse cardiovascular outcomes including age, sex, smoking history, intoxicant consumption, level of beingness exercise, and history of cardiovascular diseases.

The analyses recovered that successful nan middle-aged group, having a BMI successful nan overweight scope range (25 kg/m² to 29.9 kg/m²) was associated pinch a 13% greater consequence of dying from cardiovascular illness than those pinch a BMI successful nan normal scope (less than 25.0 kg/m²).

However, successful nan aged group, having a BMI successful nan overweight scope (25 kg/m² to 29.9 kg/m²) was associated pinch an 18% little consequence of dying compared to having a BMI successful nan normal scope (less than 25.0 kg/m²).

The narration betwixt BMI and cardiovascular decease consequence exhibited a U-shaped pattern, moreover aft stratification by age, truthful nan optimal BMI cut-off constituent was different successful nan aged and middle-aged groups. For nan middle-aged group, nan optimal BMI cut-off was 24 kg/m², whereas for nan aged group, it was 27 kg/m². Consequently, personalized curen plans tin beryllium developed successful objective settings by tailoring recommendations to different property groups.

The researchers besides recovered a affirmative narration betwixt some waist circumference and waist-to-height ratio and nan consequence of cardiovascular death. As waist circumference increased, nan consequence of cardiovascular decease besides showed a corresponding rise. When nan study organization was divided into older and middle-aged categories, this upward inclination remained consistent. Similar patterns were observed for nan waist-to-height ratio. However, nary important BMI cut-off constituent was identified.

Importantly, we show that optimal BMI for group pinch type 2 glucosuria varies by age, independent of accepted cardiometabolic consequence factors. Our findings propose that for older individuals who are moderately overweight but not obese, maintaining alternatively than losing weight whitethorn beryllium a much applicable measurement of reducing their consequence of dying from cardiovascular disease."

He adds, "Our findings besides bespeak that adiposity whitethorn connection immoderate protection against fatal diseases to immoderate extent. The imaginable biologic mechanisms that explicate this 'obesity endurance paradox' successful aged group whitethorn beryllium associated pinch a little complaint of bony wide loss, which reduces nan effects of autumn and trauma episodes, and greater nutritional reserves to accommodate periods of acute stress."

The authors opportunity that successful nan future, measures of cardinal obesity, specified arsenic waist circumference, would beryllium utilized to further refine nan risk.

This is an observational study, and arsenic such, can't found cause. And nan researchers admit various limitations to their findings, including mini numbers of cardiovascular deaths and nary accusation connected type of cardiovascular illness aliases circumstantial treatments. They besides statement that astir of nan UK Biobank study participants are White, truthful nan findings mightiness not use to group of different taste backgrounds. Also, nan quality of nan cohort study whitethorn create imaginable classification errors that could partially impact nan conclusions, because anthropometric measurements were only assessed astatine nan commencement of nan study, and assemblage weight whitethorn alteration during nan follow-up period.
