11.1 Energy Balance: Obesity Statistics


– WELCOME TO CHAPTER 9: ENERGY BALANCE AND OBESITY. IN THIS FIRST SECTION WE’LL BE GOING OVER THE
OBESITY STATISTICS. WHAT I’D LIKE TO DO IS
START WITH SOME CDC DATA. SO THIS IS THE CENTER FOR
DISEASE CONTROL AND THEIR DATA MAPPING FOR THE OBESITY
PREVALENCE IN THE UNITED STATES. AND YOU CAN SEE HERE AS
WE’RE STARTING WITH 1985, AND WE CAN LOOK AT
THE WHITE AREAS, WHICH IS JUST THE LACK OF DATA,
BUT THEN LIGHT BLUE SHOWING THE PREVALENCE OF OBESITY IN
THESE STATES IS LESS THAN 10%. AS WE GET TO A LITTLE BIT OF THE
DARKER BLUE, NOT THE REAL DARK, BUT YOU CAN SEE THAT IT’S
ABOUT 10-14% IN THESE STATES. BUT, YOU KNOW, WE DON’T
HAVE ANY OF THE STATES OVER 15% AND DEFINITELY
NO STATES OVER 30%. SO THIS IS BACK IN 1985. AND I WANT YOU TO START WATCHING
AS I CLICK THROUGH THESE SLIDES TO 1990 THAT WE’RE
STARTING TO SEE ALMOST ALL OF THE STATES NOW DO HAVE
SOME OBESITY PREVALENCE. ONE IS THAT THERE IS MORE
DATA THAT’S BEING COLLECTED, BUT ALSO YOU CAN SEE THE
INCREASE IN OBESITY AS WELL. THROUGH WE START– NOW, FINALLY BY 1995
WE DO HAVE STATES THAT DO HAVE 15-19% OF THE
POPULATION THAT IS OBESE. AND YOU CAN SEE MOSTLY
WE GO THROUGH THE MIDWEST AND THROUGHOUT
THE SOUTHERN STATES. NOW, STARTING TO GET OVER
20% IN THOSE SAME STATES WITH THOSE OTHER STATES
CATCHING UP ON THE WEST COAST. NOTICE THAT COLORADO KIND OF
SITS HERE ABOUT 10-14%. AND THIS IS IN 2000-2005,
NOW WE’RE NOT SEEING ANY BLUE, SO HARDLY ANY OF THE STATES
HAVE LESS THAN 20% OBESITY RATE. NOW, SOME OF THESE
SOUTHERN STATES, OVER 30% OF THE
POPULATION IS OBESE. AND THE MOST RECENT DATA’S
ACTUALLY OPEN UP TO 2010, BUT LOOK THROUGH THESE
SOUTHERN STATES HERE; OBESITY RATES UP
GREATER THAN 30%, THE 20-25% RATE IN THROUGH
THESE WESTERN STATES, THEN KIND OF THE NORTHWEST
AND MIDWEST IN 25-29%. SO THIS IS AN AMAZING STATISTICS OVER THE PAST FEW DECADES. THIS HAS NOT BEEN
THAT LONG. 1985. I WAS A SOPHOMORE
IN HIGH SCHOOL. SO THIS WAS AMIDST THE LOW-FAT
AGE AS WE WOULD CALL IT, THE LOW-FAT PERIOD RIGHT
IN THE MIDDLE OF THE 80’s. NOW, WHY IS OBESITY A PROBLEM? WHY DO WE CARE IF
THERE’S OBESITY? WELL, WE’RE GOING TO DISCUSS
THIS IN MORE DETAIL LATER, BUT OBESITY IS ASSOCIATED WITH
A NUMBER OF HEALTH PROBLEMS. DYSLIPIDEMIA, WHICH MEANS
ABNORMAL BLOOD LIPIDS; HYPERTENSION, WHICH IS
HIGH BLOOD-PRESSURE; TYPE 2 DIABETES, WHICH WE DISCUSSED EARLIER
IN OUR CARBOHYDRATE CHAPTER; STROKE AND HEART DISEASE; GALLBLADDER DISEASE; OSTEOARTHRITIS; SLEEP APNEA; AND RESPIRATORY PROBLEMS. NOW, THIS IS DATA
FROM THE CDC AND WE’RE LOOKING AT OBESITY RATES, WHICH WE JUST SAW,
IN COMPARISON TO DIABETES. SO LOOK AT THE INCREASE IN
PREVALENCE OF DIABETES AND HOW IT CORRELATES WITH
THE INCREASE IN OBESITY. NOW, ALTHOUGH IT’S NOT EXACT, YOU CAN SEE THAT SOME OF THESE
SAME SOUTHERN STATES INITIALLY HAVE A GREATER PREVALENCE
DOWN IN THROUGH HERE. OBESITY AS RELATED
TO THE DIABETES WITH SOME OF THE SAME STATES
THAT HAVE A LOWER RATE OF PREVALENCE OF OBESITY
ALSO DEAL WITH DIABETES. SO THERE IS A DIRECT CORRELATION
BETWEEN OBESITY AND DIABETES. NOW, WHAT ABOUT THE PERCENT OF AMERICANS WHO ARE
OVERWEIGHT NOW? WE HAVE ABOUT 30% OF THE
POPULATION HAS A HEALTHY WEIGHT. AND WE’RE GOING TO DISCUSS
THIS LATER IN THE NEXT SECTION EXACTLY HOW WE
DEFINE A HEALTHY WEIGHT. ABOUT 27% ARE OVERWEIGHT
WITH 35% OBESE. THEN WE HAVE THIS EXTREME
OBESITY AND THEN UNDERWEIGHT. AND ACTUALLY IF WE TAKE
THE OVERWEIGHT, OBESE, AND EXTREME OBESITY AND
WE LUMP THEM ALL TOGETHER THAT’S GOING TO BE 68%
OF OUR TOTAL POPULATION. 68%, SO ALMOST 70% IS
EITHER OVERWEIGHT, OBESE, OR EXTREMELY OBESE WHEREAS
ONLY 30% ARE A HEALTHY WEIGHT. THAT LEAVES THIS LITTLE
SLIVER, YOU KNOW, JUST A COUPLE PERCENT OF PEOPLE
WHO ARE ACTUALLY UNDERWEIGHT. NOW, NEXT WE’LL TALK ABOUT
EXACTLY WHY THIS IS IMPORTANT AND HOW WE DETERMINE
OVERWEIGHT AND OBESITY. SO THIS IS THE END
OF THE FIRST SECTION.
