It's derived from those same effed up actuarial weights the insurance industry developed, that give us those craptastic Ideal Body Weights. BTW, it's worth noting that the original tables & formulas were developed in the 1930s - right when food insecurity was a HUGE problem in the US and Europe.<br /><br />I would still be hesitant about the UK requirements. Daily energy needs are just about THE most variable thing EVAR, and you can multiply that by at LEAST 100 for kids. Populational "ranges" are at high probability to be off by a considerable amount. Added to this problem, is that the formulas to calculate daily caloric needs have been "tweeked" over the past decade or so, and most of the publicly available ones substantially UNDERESTIMATE caloric requirements. Even on the USDA and other "official" websites. <br /><br />(The reason for this is, of course, the Obesity Epidemic BOOGA BOOGA BOOGA, and the completely UNVALIDATED assumption that people are fat because they are eating "too much". As a result, the calculators are adjusted down.)<br /><br />However, you can still get good information if you know where to dig. Which of course, I do. Protein-calorie and micronutrient malnutrition are large risk factors for worse hospital outcomes. The assumptions the literature make for hospital ICU patients are very different from those made for all of us eating too much fat fatties on the outside.<br /><br />Here is a great pediatric monograph. The topic is (sadly) children who need tube feeding. This gives the range for a 12-18yo child as 30-60kcal / kg / day. Please note that that is a HUGE range. A 100lb kid - which would be a very small 18yo or a middlin 12yo, is about 45kg, and the range would be 1350 - 2700 for that kid. <br /><br />Now, this is baseline for a healthy kid.<br /> - a fever increases daily needs by 10-12% per increased degree C;<br /> - cardiac failure increases it by 15-25%;<br /> - surgery by 20-30%;<br /> - LONG TERM GROWTH FAILURE BY 50-100%. (caplockishness mine).<br /><br />http://www.uic.edu/classes/pmpr/pmpr652/Final/krauss/pedsnutrition.html<br />IrishUphttps://www.blogger.com/profile/00897171486597041582noreply@blogger.com
