Parents, please take note. Among the lifestyle habits that influence the risk of overweight and obesity in children, watching television is the worst, suggests new research.

“Identifying habits linked to overweight and obesity in the early stages of life can help us to define preventive strategies against other conditions, such as cardiovascular and metabolic diseases during adulthood,” said lead author of the study Rowaedh Bawaked, researcher at the Hospital del Mar Medical Research Institute in Spain.

The researchers analysed five lifestyle habits: physical activity, sleep time, television time, plant-based food consumption and ultra-processed food consumption.

The study, published in the journal Pediatric Obesity, was based on data from 1,480 children.

Parents were asked to complete various questionnaires on the children’s lifestyle habits at four years of age.

To calculate the health impact of these habits, the researchers measured the children’s body mass index (BMI), waist circumference and blood pressure at four and seven years of age.

Children who were less active and spent more time in front of the television at four years of age were at greater risk of being affected by overweight, obesity and metabolic syndrome at seven years of age, showed the findings.

The researchers also measured the time spent by the children on other sedentary activities, such as reading, drawing and doing puzzles. However, these activities did not appear to be associated with overweight or obesity.

“When children watch TV, they see a huge number of advertisements for unhealthy food,” said co-leader of the study Dora Romaguera from Barcelona Institute for Global Health in Spain.

“This may encourage them to consume these products,” Romaguera said.

Ultra-processed foods, such as pastries, sweet beverages and refined-grain products, are high in sugar, salt and saturated fat and low in nutritional value.

The study showed that high intake of these products at four years of age was associated with a higher BMI at seven years of age.

Moreover, television viewing “discourages physical activity and interrupts sleep time”, explained Silvia Fernandez, a post-doctoral researcher at Barcelona Institute for Global Health.

As the researchers noted, adequate sleep time in early childhood is essential for weight control later in childhood.

The study concluded that adult health depends on the establishment of healthy lifestyle habits during childhood: limited television time, extracurricular physical activity, getting enough hours of sleep, eating lots of vegetables and avoiding ultra-processed foods. (IANS)

Heart patients, please take note, here’s a new health news. Researchers have found that heart attack survivors who carry excess fat around their waist are at increased risk of another heart attack.

“Abdominal obesity not only increases your risk for a first heart attack or stroke, but also the risk for recurrent events after the first misfortune,” said study author Hanieh Mohammadi from the Karolinska Institute in Sweden.

Prior studies have shown that abdominal obesity is an important risk factor for having a first heart attack. But until now, the association between abdominal obesity and the risk of a subsequent heart attack or stroke was unknown.

The research, published in the European Journal of Preventive Cardiology, followed more than 22,000 patients after their first heart attack and investigated the relation between abdominal obesity (measured by waist circumference) and the risk for recurrent cardiovascular disease events. The researchers specifically looked at events caused by clogged arteries, such as fatal and non-fatal heart attack and stroke.

Patients were recruited from the nationwide SWEDEHEART registry and followed for a median of 3.8 years. Most patients — 78 per cent of men and 90 per cent of women — had abdominal obesity (waist circumference 94 cm or above for men and 80 cm or above for women).

Increasing abdominal obesity was independently associated with fatal and non-fatal heart attacks and strokes, regardless of other risk factors (such as smoking, diabetes, hypertension, blood pressure, blood lipids and body mass index [BMI]) and secondary prevention treatments. According to the researchers, waist circumference was a more important marker of recurrent events than overall obesity.

The reason abdominal obesity is very common in patients with a first heart attack is that it is closely linked with conditions that accelerate the clogging of arteries through atherosclerosi, the researchers said. These conditions include increased blood pressure, high blood sugar and insulin resistance (diabetes) as well as raised blood lipid levels.

“Our results, however, suggest that there may be other negative mechanisms associated with abdominal obesity that are independent of these risk factors and remain unrecognised,” Mohammadi said.

“In our study, patients with increasing levels of abdominal obesity still had a raised risk for recurrent events despite being on therapies that lower traditional risk factors connected with abdominal obesity such as anti-hypertensives, diabetes medication and lipid lowering drugs,” she added.

According to the study, the relationship between waist circumference and recurrent events was stronger and more linear in men.

“There were three times as many men in the study compared to women, contributing to less statistical power in the female group. Therefore, more studies are needed before definite conclusions can be drawn according to gender,” Mohammadi noted. (IANS)
