Harvard study: More children showing signs of adult illnesses like hypertension

The goal of this society should be to raise healthy and happy children who will grow into concerned and involved adults who care about their fellow citizens and environment. In order to accomplish this goal, all children must receive a good basic education and in order to achieve that goal, children must arrive at school, ready to learn. There is an epidemic of childhood obesity and obesity is often prevalent among poor children. The American Heart Association has some great information about Physical Activity and Children http://www.heart.org/HEARTORG/GettingHealthy/Physical-Activity-and-Children_UCM_304053_Article.jsp#.TummU1bfW-c
Because many children are obese, they are at increased risk of adult diseases.

Alexandra Sifferlin reports in the Time article, Sick Before Their Time: More Kids Diagnosed With Adult Diseases:

Diabetes, obesity and elevated blood pressure typically emerge in middle-age, but more young children are showing signs of chronic conditions that may take a toll on their health.
The latest report on the trend, from researchers at Harvard Medical School found that children and adolescents are increasingly suffering from elevated blood pressure. Published in the American Heart Association journal Hypertension, the study showed a 27% increase in the proportion of children aged 8 years to 17 years with elevated blood pressure over a thirteen-year period.
The scientists compared over 3,200 children involved in the National Health and Nutrition Examination Survey (NHANES) III in 1988-1994 to over 8,300 who participated in NHANES in 1999-2008. The national survey records health, eating and lifestyle behaviors of the volunteers. More kids in the recent survey were overweight, with larger waistlines than those in the previous cohort. And the children with body mass index (BMI) readings in the top 25% of their age group were two times more likely to have elevated blood pressure than the kids in the bottom 25%.
The kids did not have diagnosed hypertension, which requires a threshold of 140 -90, but elevated blood pressure — anything above 120-80 — at such young ages could prime them for hypertension later. “High blood pressure is dangerous in part because many people don’t know they have it,” said lead study author Bernard Rosner, a professor of medicine at Harvard Medical School in a statement.
The results are only the latest to reveal the first signs of chronic conditions that normally don’t occur until middle-age, in children and teens.

Abstract
The obesity epidemic in children makes it plausible that prevalence rates of elevated blood pressure (BP) are increasing over time. Yet, previous literature is inconsistent because of small sample sizes. Also, it is unclear whether adjusting for risk factors can explain longitudinal trends in prevalence of elevated BP. Thus, we analyzed a population-based sample of 3248 children in National Health and Nutrition Examination Survey (NHANES) III (1988–1994) and 8388 children in continuous NHANES (1999–2008), aged 8 to 17 years. Our main outcome measure was elevated BP (systolic BP or diastolic BP ≥90th percentile or systolic BP/diastolic BP ≥120/80 mm Hg). We found that the prevalence of elevated BP increased from NHANES III to NHANES 1999–2008 (Boys: 15.8% to 19.2%, P=0.057; Girls: 8.2% to 12.6%, P=0.007). Body mass index (Q4 versus Q1; odds ratio=2.00; P<0.001), waist circumference (Q4 versus Q1; odds ratio=2.14; P<0.001), and sodium (Na) intake (≥3450 mg versus <2300 mg/2000 calories; odds ratio=1.36; P=0.024) were independently associated with prevalence of elevated BP. Also, mean systolic BP, but not diastolic BP, was associated with increased Na intake in children (quintile 5 [Q5] versus quintile 1 [Q1] of Na intake; β=1.25±0.58; P=0.034). In conclusion, we demonstrate an association between high Na intake and elevated BP in children. After adjustment for age, sex, race/ethnicity, body mass index, waist circumference, and sodium intake, odds ratio for elevated BP in NHANES 1999–2008 versus NHANES III=1.27, P=0.069.

The issue of childhood obesity is complicated and there are probably many factors. If a child’s family does not model healthy eating habits, it probably will be difficult to change the food preferences of the child. Our goal as a society should be:

A healthy child in a healthy family who attends a healthy school in a healthy neighborhood ©
