Introduction to obesity

In a Nutshell: More people are overweight than underweight today! Think of it like this: If we were a pack of gummy bears, there'd be more double-sized gummies than regular ones. That's the "obesity pandemic".

 

Real-World Example: In 2014, imagine 1.9 billion adults as a huge crowd. Now, from that crowd, imagine about a third, or over 600 million people, as extra chubby. That's the number of obese adults globally in 2014!

 

Worth Remembering: Obesity can be prevented. It's like a game, and there are strategies to keep winning.

What is obesity?

In a Nutshell: Obesity is when you've got more body fat than is healthy. It's like carrying around a backpack full of textbooks all the time.

 

Fun Fact: We measure obesity using the Body Mass Index (BMI), an idea from the 19th century. It's like an old-fashioned bathroom scale! But some people think it's not the best measure.

 

Real-World Example: In a class of 25 students, if everyone's weight in kg is divided by their height in m squared (that's how BMI is calculated), and more than a quarter of the class has a BMI over 25, they'd be considered overweight.

How is besity data collected?

In a Nutshell: Data on obesity is collected from various places - surveys, schools, health services, and cohort studies (like class photos, but for health!). But it's not perfect, as people might fudge their numbers a bit (like when you say you've done all your homework, but you haven't).

 

Real-World Example: Imagine you're part of a school health check-up where they measure your height and weight. This information can be used to track changes in obesity levels over time.
