00:00:00.593 --> 00:00:04.237
Waist-to-height ratio is one division, but a useful

00:00:04.150 --> 00:00:06.594
answer starts with a consistent measurement.

00:00:06.907 --> 00:00:09.312
Moving the tape to whichever position gives the

00:00:09.225 --> 00:00:12.269
smallest number changes the comparison before you even

00:00:12.182 --> 00:00:12.962
calculate it.

00:00:13.838 --> 00:00:15.976
Find the bottom of the ribs and the

00:00:15.890 --> 00:00:16.962
top of the hips.

00:00:17.248 --> 00:00:20.012
Place the tape midway between them, keep it

00:00:19.926 --> 00:00:21.997
level, and breathe out naturally.

00:00:22.310 --> 00:00:24.528
Do not deliberately pull your abdomen in.

00:00:25.293 --> 00:00:27.938
Use the same units for waist and height.

00:00:28.237 --> 00:00:31.534
Eighty-four centimetres divided by one hundred seventy-five

00:00:31.447 --> 00:00:34.425
centimetres equals zero point four eight.

00:00:34.738 --> 00:00:37.981
Centimetres divided by inches would give a meaningless

00:00:37.881 --> 00:00:38.754
comparison.

00:00:39.528 --> 00:00:42.678
NICE uses this measure alongside BMI for adults

00:00:42.592 --> 00:00:44.796
with BMI below thirty-five.

00:00:45.096 --> 00:00:47.407
It can add screening information, but it does

00:00:47.320 --> 00:00:50.138
not diagnose a disease or measure an exact

00:00:50.051 --> 00:00:51.736
body-fat percentage for you.

00:00:52.458 --> 00:00:55.009
Record the measurements, units and date.

00:00:55.309 --> 00:00:58.019
If the number changes, check your method before

00:00:57.933 --> 00:01:00.137
assuming a major change in your body.

00:01:00.424 --> 00:01:03.481
A consistent record is more useful than repeated

00:01:03.394 --> 00:01:05.466
adjustments during one session.

00:01:06.211 --> 00:01:09.294
A ratio cannot choose a supplement or treatment.

00:01:09.607 --> 00:01:12.012
Put it alongside the wider health picture.

00:01:12.338 --> 00:01:16.194
