Blog Assignment 10


The CDC states that the percentage of children aged 6-11 years in the United States who were obese increased from 7% in 1980 to almost 20% in 2008 (CDC). The relevance of this age group is that it generally represents children at the elementary school age, which is also a crucial stage of development. Obesity at this age can lead to significant immediate and long-term health effects. For example, a population based sample of 5 to 17 year olds showed that 70% of obese youth had at least one risk factor for cardiovascular disease (CDC). Furthermore, children who are obese are more likely to be obese as adults, so it is easy to see the impact obesity can have on a child throughout their whole life.

The magnitude of this problem is great and what is even more staggering is the rapidity with which the rates have climbed over the last 30 years or so. What is most interesting about this increases that took place over different racial and ethnic groups. While there has been an increase in obesity prevalence overall in children there was an increase in prevalence from 10.7% to 19.8% among non-Hispanic black boys, from 14.1% to 26.8% among Mexican-American boys, but just an increase from 11.6% to 16.7% among non-Hispanic white boys (CDC). This trend is similar for girls. There was an increase in prevalence from 8.9% to 14.5% among non-Hispanic white girls, from 16.3% to 29.2% among non-Hispanic black girls, from 13.4% to 17.4% among Mexican-American girls (CDC).

An indirect indicator of differences in prevalence of childhood obesity among different ethnic and racial groups can be displayed in the number of fast food restaurants in different neighborhoods. An archive study in New Orleans found that Predominantly black neighborhoods have 2.4 fast-food restaurants per square mile compared to 1.5 restaurants in predominantly white neighborhoods (Archive).

  1. Focusing on such a young age group is definitely ideal, especially because that's the age during which eating habits develop that are then carried by children for the rest of their lives. The difference in obesity rate increases between racial and ethnic groups is really interesting, especially because the groups are so specific, consisting of race or ethnicity, as well as gender (specifically boys). It's good that your topic is something that can be studied at a level this specific, that's really beneficial to your paper! Your indicators so far are also very clear and effective; I agree with you in that obesity is partially caused by environmental factors such as the presence of fast food restaurants. I'm curious to see whether you treat this public health issue as the responsibility of the individual or of society or both, and even more curious to see whether you're going to discuss solving this problem in a preventive way in an attempt to protect future generations or in a curative way, focusing on those who are already suffering from obesity.
