The waist size thing reminds me of something that is relevant given this is feminist topic.
It was a couple of years ago and a couple of papers & BBC maybe had a headline saying something along the lines of "women with larger waists at risk" and the articles were all about how women who had "pear" shape bodies were less likely to get cardiovascular issues etc and they mooted whether this was to do with a protective effect of more female hormones or fat stored away from heart in bum & thighs etc etc etc.
Anyway the whole thrust was that women without a "classic" female shape of small waist wider hips were at risk because of their body shape.
The first thing I thought was well that's a bit shit as you can't change where on your body you store fat when you have any!
Then the next thing I thought was, that as an apple shape, my mum once described me as having a "male distribution of fat". Which makes sense, apple women put on weight around their middles not their hips and arse which is what most men do.
So about these articles, I thought what they actually meant was that apple women and teh vast majority of men are at a disadvantage as they put weight around their middles not their arses.
And then I got really pissed off, because men weren't mentioned in any of the articles at all. It was all about women being this shape, that shape, right shape, wrong shape. In big capital letters. And all of the men? Not a mention.
So spotting the media bias and kind of making sure you note it can help. As it's invariably women. Like when they have a "OMG people are getting fat" story the accompanying picture / film clip almost always shows fat women / fat women's bottoms. I think things are getting a bit more even with that, they occasionally show a man with tummies eating chips now but for years and still most of the time now a story about the nation getting fatter will be accompanied by a picture of a woman.
