The prevalence of obesity among children is increasing at an alarming rate. Overweight four-year-old children have twice the risk of high blood pressure by the age of six years. This heightens the risk of future heart attack and stroke. The World Health Organization (WHO) has listed childhood obesity among the most serious public health challenges of the 21st century.

Obesity is a multifactorial disorder; unhealthy diet – eating foods high in fats, sugar and salt (junk food, processed food) and a sedentary lifestyle (TV, internet, computer and mobile games have taken precedence over outdoor sports) contribute significantly to this escalating epidemic. Women should lose those extra pounds before conceiving, avoid gaining excess weight during pregnancy, and quit smoking, as these are known risk factors for childhood obesity.

Most obese children grow up to have obesity in adulthood. Overweight and obese children are at risk of other lifestyle disorders such as type 2 diabetes, hypertension, dyslipidemia, metabolic syndrome later in life. They are more likely to have joint problems, sleep apnea and social and psychological problems.

Healthy habits in childhood lay a foundation for a healthier adulthood. Here are some tips that parents can follow at home to tackle obesity and unhealthy habits in children:

  • Encourage healthy eating habits right from the begining.
  • Try making the dishes healthier. Few changes can make the snacks healthier.
  • Avoid tempting children with calorie-rich food. Treat them but in moderation and by limiting high-fat and high-sugar or salty snacks.
  • Make kids understand the importance of being physically active.
  • Indulge yourself in at least 60 minutes of moderate to intense physical activity every day and set an example for your kids
  • Reduce sedentary time. While reading is a good option, too much of screen time is not good.
  • Replace screen time with outdoor fun activities to keep children engaged.

Nine modifiable risk factors for heart attack

The majority of known risk factors for heart attack are modifiable by specific preventive measures.

The nine potentially modifiable factors include smoking, dyslipidemia, hypertension, diabetes, abdominal obesity, psychosocial factors, regular alcohol consumption, daily consumption of fruits and vegetables and regular physical activity. These account for over 90% of the population attributable risk of a first heart attack.

In addition, aspirin is recommended for primary prevention of heart disease for men and women whose 10-year risk of a first heart attack event is 6% or greater.

Smoking cessation reduces the risk of both heart attack and stroke. One year after quitting, the risk of heart attack and death from heart disease is reduced by one-half, and after several years, begins to approach that of nonsmokers.

A number of observational studies have shown a strong inverse relationship between leisure time activity and decreased risks of CVD. Walking 80 minutes in a day and whenever possible with a speed of 80 steps per minute are the current recommendations.

A too-tight shirt collar can indicate future heart trouble. The standard ways to assess obesity is to measure the waistline and determine body-mass index.

An obese person can be pear-shaped, with most of the non visceral excess fat weight around the hips; or apple-shaped, with most of the visceral fat weight in the upper part of the body. Cardiologists up till now have been measuring the abdominal fat to help assess the risk of heart disease but now fat in the neck has been shown to be associated with good cholesterol levels and diabetes.

Waist circumference represents visceral fat in the abdomen and neck fats denote visceral fat in the upper body. Both independently contribute to cardio metabolic risk. A fat neck is a ‘crude measure’ of upper body fat.

The Framingham Heart Study using data on 3,320 people has shown that “Neck circumference is associated with cardio-metabolic risk factors, even after adjustment for visceral fat. While risk was higher regardless of waistline, it was compounded for those who had both a fat neck and who were larger than average around the middle.

The research findings

1. Average neck circumferences were 40.5cm in men and 34.2 cm in women.

2. For every nearly-3 cm more of neck, men had 2.2 mg/dl less good HDL cholesterol.

3.  For every nearly-3 cm more of neck, women had 2.7 mg/dl less good HDL cholesterol.

4. For every nearly-3 cm more of neck, men had 3.0 mg/dl more blood glucose levels.

5. For every nearly-3 cm more of neck, women had 2.1 mg/dl more blood glucose levels.

Implications

1. 1% reduction in HDL cholesterol increases the chances of heart attack by 3% and vice versa.

2. In adults with a BMI of 22.9 to 34.9 kg/m2, a waist circumference greater than 85 cm for men and 80 cm for women is associated with a greater risk of hypertension, type 2 diabetes, and dyslipidemia, and heart disease.

3. In patients with a BMI ≥ 35 kg/m2, measurement of waist circumference is less helpful since it adds little to the predictive power of the disease risk classification of BMI; almost all individuals with this BMI also have an abnormal waist circumference.

4. A neck circumference of > 42.5 cm is also associated with snoring with sleep apnea and subsequent high blood pressure.
