Image National growth charts for boys (left) and girls (right) from birth to age 3, published by the C.D.C. Credit Centers for Disease Control and PreventionThe first “national” growth charts were produced in 1977 and pulled height, weight and head circumference measurements from large cross-country health surveys. These data points provide the basis for the curves and percentiles you’ve become accustomed to seeing in the pediatrician’s office today. If your 6-month-old’s weight is at the 75th percentile, for instance, roughly 75 percent of 6-month-olds across the country weigh less than your child and 25 percent weigh more. If her height is at the 90th percentile, 90 percent of children her age are shorter than her and 10 percent are taller.However, the data upon which those charts relied was suboptimal.
The CDC growth charts should be used in this population, with consideration of the potential influence of specific conditions on growth. Disease-specific growth charts (ie, Down syndrome) may be used in conjunction with the CDC charts.
Those national surveys, for instance, didn’t contain data for kids from birth to 12 months — which are the ages that parents obsess over the most — so experts had to turn to a different data source. That new source, however, had: Almost all of the infants in the data set were formula-fed, white, middle-class infants living in southwest Ohio. There was no reason to believe that children with different backgrounds, ethnicities or diets would (or should) grow similarly.In 2000, the Centers for Disease Control and Prevention charts to include more nationally representative information about kids in their first year. Then, confusing things further, the World Health Organization released its own version for children between 0 and 5, focusing on how kids should grow under optimal conditions (such as being breastfed and living in safe, comfortable, smoke-free homes).
Because some experts believed that the W.H.O.’s charts for 0-to-2-year-olds were better than those produced for those age ranges from the C.D.C., the C.D.C. Recommended in 2010 that pediatricians start using the W.H.O. Charts until children were 2, and then switch back to C.D.C. Charts after that.

Growth charts for girls (left) and boys (right) from birth to age 2, published by the C.D.C. Credit Centers for Disease Control and PreventionEven with those improvements, however, the charts are still imperfect.
Those lines you see on the growth chart don’t represent a single child’s growth — they’re an amalgam of measurements of millions of kids at different ages. So while they might give you the impression that children are supposed to follow them (or stay on the curve), there’s no reason to think that’s the case. No study says that a child who is at the 25th percentile for weight at 2 months, for instance, should remain there at 4 months or 6 months.But parents struggle to grasp this reality. They think that if a child measures at a certain percentile once or twice, that’s destiny. They think if their child goes up or down, that’s a problem. It’s often not.How do we know this?
My colleagues and I in 2014, where we used our local clinical records to plot nearly 10,000 kids’ heights and weights across their first year of life. Experts make growth charts, remember, by measuring many kids of different ages at one point in time and then plotting those measurements into curves. Our team, on the other hand, followed the same children over multiple points across their first year to see how their measurements, and percentiles, changed.We found that they go all over the place. From birth to 12 months, about two-thirds of the children fell by at least one percentile line with respect to weight (meaning they went from the 10th to fifth percentile, for example, or the 90th to 75th). More than one-third dropped by at least two lines. And of the entire group, more than 30 percent dropped by at least two lines over a six-month period, which meets the clinical definition of “failure to thrive.”Yet almost none of these kids were “failing to thrive.” Most were just growing at different rates. By the close of the one-year study period, just 27 percent of the children ended up at the same percentile line they started at.Should we update the growth charts with our data?
We were studying a mostly minority patient population, most of them covered by Medicaid. They were no more nationally representative than the population that made the 1997 growth charts. But our study did show that parents (and doctors) should not necessarily be alarmed when kids move from one percentile to another. Instead, they should take those numbers with a grain of salt and consider that most kids are just fine.Moreover, too many people don’t understand percentiles. That while most parents have seen and think they know how to interpret a growth chart, most actually don’t know how to correctly explain its meaning. There’s nothing inherently good or bad — normal or not normal — about any one number. Being at the 90th percentile for height isn’t better than being at the 25th percentile, no matter how strange that sounds to our grade-obsessed-brains.
Some kids are meant to be shorter and some taller. I see far too many parents worried that their child is at the 10th percentile for height, as if that means they’ll never get into college.In fact, we are socially wired to think that bigger — in terms of height and weight — is better.
Authors of a in 2012, for instance, asked 281 mothers to assess their toddlers’ body size. About 70 percent of the assessments were inaccurate. The mothers of toddlers who were overweight were 87 percent less likely to recognize that their kids were heavy compared to mothers of toddlers who were a healthy weight.In other words, we’ve come to see heavy toddlers as “normal.”Growth charts were originally intended to help doctors catch kids who truly were “off the chart” in one way or another. Then they became a tool to track kids over time, so that pediatricians seeing a new child could have a sense of their growth history.
They were never intended to be a way to grade a child’s health.But we’ve seen that problems can arise when parents focus too much on the numbers. A few weeks ago, a colleague who has a 4-month-old told me that she became concerned when she learned at a recent pediatrician visit that her daughter had gone from the 50th percentile for weight at birth to the 25th months later.
She considered running to her daughter’s day care each day to feed her supplemental breastmilk to catch her up.I probably didn’t control my eye-roll too well. Just because she was at a higher percentile at 2 months didn’t mean that she needed to stay there. And since my colleague, who was 5 feet tall, was far below the national average for height (and likely weight), her daughter was probably going to be on the lower end of the spectrum as well. Trying to reverse that trend by feeding her more wasn’t going to help.Of course, you should never ignore sudden changes in weight or height, or significant changes that occur suddenly after years of steady progress. Changes that are coupled with symptoms that indicate a health concern, or significant growth in weight that is unaccompanied by growth in height, are important to flag as well. But a good doctor will be able to help you determine if your child is gaining, or failing to gain, weight in an unhealthy fashion. A good doctor will also almost always tell you to remain calm and not rely too much on the numbers.Worried about your kid’s weight?Aaron E.

Growth curve of a girl, compared to the 2006 WHO curves.A growth chart is used by and other health care providers to follow a child's growth over time. Growth charts have been constructed by observing the growth of large numbers of normal children over time. The, and of a child can be compared to the expected parameters of children of the same age and sex to determine whether the child is growing appropriately.
Growth charts can also be used to predict the expected adult height and weight of a child because, in general, children maintain a fairly constant growth curve. When a child deviates from his or her previously established growth curve, investigation into the cause is generally warranted. For instance, a decrease in the growth velocity may indicate the onset of a chronic illness such as. Sample growth chart for use with American boys from birth to age 36 months.Growth charts can also be compiled with a portion of the population deemed to have been raised in more or less ideal environments, such as nutrition that conforms to pediatric guidelines, and no.
Charts from these sources end up with slightly taller but thinner averages.Growth charts are different for boys and girls, due in part to pubertal differences and disparity in final adult height. In addition, children with diseases such as and follow distinct growth curves which deviate significantly from children without these conditions.
As such, growth charts have been created to describe the expected growth patterns of several genetic conditions.Since there are differences in normal growth rates between breastfed and formula-fed babies, the World Health Organization growth charts, which better reflect the growth pattern of the healthy, breastfed infant are considered the standard for U.S. Children under age two.
