News about childhood obesity is everywhere these days. Hardly a day goes by without a screaming headline in the media about this issue. Jamie Oliver has further popularized it by his TV show and even Mrs Obama has taken up this cause via her Let’s Move campaign. There is no doubt that we must address childhood obesity, but what about the problem of underweight and short stature? How worried should a parent be if their toddler falls under the 5th percentile in weight and height?
Recently, registered dietitian Teresa Wagner tackled a reader question in our Ask the Expert column about a toddler not gaining weight. I received a follow up email from another reader who was worried that her 8 month old child was below the 5th percentile and not eating much. The tone of her message reflected her extreme worry and frustration at not knowing what to do.
There is a reason why our media does not focus on this problem. The numbers, when taken as a whole nationwide are not that high. See below a chart based on the 2008 data CDC’s Pediatric Nutrition Surveillance System (PedNSS) on growth indicators. The PedNSS system is a public health surveillance system which monitors the nutritional status of children from low income families under Federal programs. Data comes from public health clinics where these children are seen for routine care, nutrition education and supplemental food.
Percentage of children 2-5 years old who are underweight or of short stature is between 3-5% for Whites, Blacks and Hispanics. These numbers are even smaller for American Indians and Alaskan Natives. Compared to the 20-30% obesity rates, these numbers are too low to capture the attention of mainstream media and policy makers. Besides, the media loves to show extreme images of either very fat kids or severely malnourished starving kids from the third world countries. Anything else does not make the cut for prime time!
As a parent, it is natural to worry. It becomes a personal issue and fancy nationwide statistics do not make a difference. The frustrating part is that it is not always possible to get enough credible information to make informed decisions. The result is that each day becomes a battle to force feed a child in the hope that she will put on some weight. Since children have a natural ability to regulate their food intake based on their current needs, it may seem like they are not eating enough. Anger, frustration and despair are the emotions most parents feel under these circumstances.
Here are 5 questions you can consider to assess the situation and take appropriate actions
Is there a trend in my child’s growth chart numbers?
A single data point on the growth chart, although important, should not cause concern. Take time to understand growth charts and their limitations so you can use them to evaluate the general growth pattern of your child. Another thing to keep in mind is that your child may not be in the normal range for both weight and height. For example, our twins are tall for their age group but lag behind in weight. From this perspective, I like the BMI for age chart because it takes into account both weight and height at the same time. You can use this online calculator for BMI chart or ask your doctor about it.
Is there a medical reason for slow growth?
This is where keeping a close eye on your child’s growth pattern will help you find medical issues that may be affecting her growth. There may be known birth defects or undiagnosed metabolic or digestive disorders. Severe case of reflux like GERD is also a concern. Detecting them early and working with a specialist for corrective action is very important.
Is there a specific reason for poor appetite?
Nearly all toddlers are picky eaters and it is natural for them to frequently show poor appetite. But if it persists over a long period of time, you will need to be extra vigilant so you can find the root cause. Are there food allergies? Special environmental or seasonal triggers? Does a change in menu or feeding schedule help? The important thing is to pay attention to the unique needs of your child so each feeding is most effective. Siblings around the same age, twins or multiples need different treatments based on their individual personalities. Clearly a challenge for most parents, but there is no perfect answer. Practicing the principles of attachment parenting and nutrition can help.
Does my child seem different than his siblings or other family members?
Although it is not always a good idea to compare your children, you have to take into account your family history and genetic makeup. In some ways, a consideration of these factors is probably more important than the growth charts which are based on population averages. If your family ethnicity is not one of mainstream population, it is unlikely that the growth chart standards will be accurate for your child. Evaluate your child’s height, weight and BMI through the lens of your family’s history to determine if there are differences you should be concerned about.
Are there any special circumstances in my family?
Every family goes through ups and downs – financial, emotional or health-related – often over an extended period of time. Assess if you have certain stresses in your personal life or your family situation at the moment. Even toddlers pick on them easily even if they cannot articulate it. If these problems persists over a long period, there may be slow weight gain or even a loss in weight. Recognize these problems early and seek help from family, friends or your doctor to manage them.
One last thing to remember – early childhood height and weight is often a poor predictor of adult height and weight, except in the case of overweight or obesity. You may be surprised how fast your child can grow upon reaching puberty. Keep a close eye on the growth charts, spot the problems early and take appropriate action. No need for excessive worry just because of a couple of low points on the charts!
Most importantly, focus on building healthy eating habits. Offer a variety of foods in healthy balance and moderation.
