New study: Being fat does not make you die earlier

Please read this and pass it around:

Mortality risk for overweight and obese is no greater than for ‘normal’ when hypertension and diabetes are controlled for, (Anthony Jerant, Peter Franks. “Body Mass Index, Diabetes, Hypertension, and Short-Term Mortality: A Population-Based Observational Study, 2000–2006” J Am Board Fam Med July-August 2012 vol. 25 no. 4 422-431)

It’s been added to the Truth About Fat page.

A quote:

Methods: This was a population-based observational study of data from 50,994 adults aged 18 to 90 years who responded to the 2000 to 2005 Medical Expenditures Panel Surveys. Cox regression analyses were employed to model survival during up to 6 years of follow-up (ascertained via National Death Index linkage) by self-reported BMI category (underweight, <20 kg/m2; normal weight, 20-<25 [reference]; overweight, 25-<30; obese, 30-<35; severely obese, ≥35), without and with adjustment for diabetes and hypertension. Survival by BMI category also was modeled for diabetic and hypertensive individuals. All models were adjusted for sociodemographics, smoking, and Medical Expenditures Panel Surveys response year.

Results: In analyses not adjusted for diabetes or hypertension, only severe obesity was associated with mortality (adjusted hazard ratio, 1.26; 95% confidence interval, 1.00–1.59). After adjusting for diabetes and hypertension, severe obesity was no longer associated with mortality, and milder obesity (BMI 30-<35) was associated with decreased mortality (adjusted hazard ratio, 0.81; 95% confidence interval, 0.68–0.97). There was a significant interaction between diabetes (but not hypertension) and BMI (F [4, 235] = 2.71; P = .03), such that the mortality risk of diabetes was lower among mildly and severely obese persons than among those in lower BMI categories.

Conclusions: Obesity-associated mortality risk was lower than estimated in studies employing older BMI data. Only severe obesity (but not milder obesity or overweight) was associated with increased mortality, an association accounted for by coexisting diabetes and hypertension. Mortality in diabetes was lower among obese versus normal weight individuals.

    So those of us who are DEATHFATZ and don’t have any problems with blood pressure or blood sugar aren’t going to drop dead within 5 five years if we don’t lose weight like, yesterday? Gee, I think I could have told them that, even though I’m not a statistic, I’m just anecdotal evidence, seeing as how I’ve been DEATHFATZ for over 35 of my 58 years of life and haven’t dropped dead yet (and have had that normal blood sugar, blood pressure, AND cholesterol the whole time). I want to print out that study and shove it in my doctor’s face so I can tell him to STFU already about my “risk factors” because I’m so damned fat. He’s a new doctor, and another in a long line of doctors who espouse the party line of calories in/calories out and being fat is bad for you/it’s going to shorten your life (like the years it’s going to take off my life are the good ones anyway – the ones I’d be spending in a nursing home having someone change my diapers and wipe my ass? I don’t think so).
