By Ejaromedoghene Ofuoma

Introduction

Educating teenagers about heart health is crucial for building lifelong healthy habits. Many teenagers are under the impression that one can get heart diseases much later in life, but heart diseases do start early. Preconceived notions about who is at risk of getting heart problems and what those problems are can lead to neglecting important lifestyle choices. According to the American Heart Association (AHA), early education about heart health can significantly reduce the risk of heart-related issues later in life. By addressing misconceptions of teenagers about heart health and providing useful tips, we can help teenagers take proactive steps toward maintaining a healthy heart.

1.      Heart disease only affects older adults

The most common misconception about heart disease is that it only happens to old people. In reality, diseases of the heart and blood vessels may develop at early ages of childhood /adolescence due to early personal decisions and habits such as lack of adequate physical activity; consumption of poor and quality nutrition; and exposure to tobacco or alcohol use during the adolescent years. Teenagers with these habits are at risk of contracting cardiovascular diseases later in their lifetime (The Centres for Disease Control and Prevention (CDC). Johns Hopkins Medicine notes that plaques may start to form in the arteries in teenage years and lead to diseases such as atherosclerosis as the individual ages. While the symptoms may not appear until adulthood, the damage often starts in youth.

2.      Only Overweight People Have Heart Problems

Another common misconception is that only overweight individuals develop heart disease. While obesity is a risk factor for heart conditions, slim individuals can also have heart problems due to genetic predispositions, stress, or a lack of exercise. While obesity is a risk factor for heart disease, it is important to note that slim individuals can also develop heart issues. Genetics, stress, and lack of exercise can contribute to heart problems, regardless of body weight. The British Heart Foundation emphasizes the importance of focusing on overall lifestyle choices and genetic factors rather than body weight alone. [2]

3.     Your Heart is Fine; if You Don’t Have Symptoms

It is dangerous to assume that the absence of visible symptoms indicates a healthy heart. Some heart conditions, such as hypertension, onset of coronary artery disease and high cholesterol, may not show symptoms until they get to advanced stages. Hence, preventive care and regular check-ups are crucial for early detection and treatment because heart disease can progress without noticeable signs of heart problems.

Moreover, Hopkins Medicine suggests that teenagers with a family history of heart disease, should have their cholesterol levels, blood pressure, and overall heart health monitored periodically. Early diagnosis and lifestyle adjustments can help manage conditions before they worsen.

Finally, the importance of heart health is a crucial aspect of overall well-being, and it is essential to start developing healthy habits early in life. Heart disease is not just a concern for older adults or overweight individuals—it’s something that everyone, including teenagers, should be aware of. Preventive care and regular check-ups play a vital role in catching potential problems before they become serious.

The Impact of Technology and Screen Time on Heart Health 

By Ejaromedoghene Ofuoma

Technology and screen time have become integral parts of children’s daily routines in today’s digital age. Children and teenagers are spending more time in front of screens than ever before, either through cell phones, computers, or gaming consoles. While technology offers educational and entertaining benefits, there is rising worry about its impact on children’s health, particularly their cardiovascular health. According to the World Health Organization (WHO), the increasing frequency of sedentary behaviours associated with excessive screen time is a significant risk factor for chronic illnesses such as obesity and heart disease. The impact of technology and screen time on cardiovascular health can be explored through: examining lifestyle choices; its impact on mental and emotional health; and recommendations on the safe way to use technology. 

Lifestyle and Heart Health

The association between prolonged screen time and decreasing physical activity is a big concern. Children who spend much time in front of screens frequently miss out on important physical activities like riding, walking, or even running. This lack of movement can result in a sedentary lifestyle, which increases the risk of heart conditions like obesity, high blood pressure, and high cholesterol levels. 

This behaviour also contributes to the development of other conditions like hypertension (high blood pressure), which can lead to long-term cardiovascular complications. A study published in the Journal of the American College of Cardiology emphasised that even small increases in daily sedentary time are associated with higher risks of cardiovascular events in children as they age.

The impact of screen time on mental and emotional health

The American Psychological Association (APA) found that children and teens who are frequently exposed to negative social interactions online may experience heightened levels of stress, which can increase blood pressure and trigger harmful physiological responses. Stress can also increase the production of cortisol, a hormone that, when elevated over long periods of time, can contribute to the development of cardiovascular issues such as increased heart rate and hypertension. These psychological effects of excessive screen time can indirectly contribute to cardiovascular problems. In addition, stress and anxiety stemming from social media, gaming, or other online activities can have a significant impact on a child’s heart health.

Safe Utilisation of Technology: The Way Forward

Health organisations have made some recommendations to assist parents and kids in finding a balance between screen time and exercise:

  •  Younger children should have even tougher guidelines, with the American Academy of Paediatrics (AAP) recommending that children six years old and older limit their recreational screen usage to no more than two hours per day; 
  • In order to maintain a healthy body and heart, the WHO also recommends that kids and teenagers participate in moderate-to-intense physical exercise for at least 60 minutes per day; 
  • It’s essential to motivate kids to walk more throughout the day in order to lessen the negative impacts of screen time on heart health. This might be as easy as stepping away from screens to stretch, going for a stroll, or taking part in sports; 
  • In addition, parents ought to set an example of good health by cutting back on their own screen time and giving family time to engage in physical activities like riding or hiking. 

Despite the fact that modern life involves technology and screen time, excessive use of either can lead to a sedentary lifestyle that is awful for heart health. In addition, to keeping an eye on their kids’ screen time, parents should also promote heart-healthy behaviours like frequent exercise and stress reduction. Children can reap the benefits of both technology use and active living without compromising their cardiovascular health by striking a balance between the two.

Recognising Cardiovascular Conditions in Youth and Adolescents

By Ejaromedoghene Ofuoma

Cardiovascular diseases (CVD) are a major global health issue, contributing significantly to worldwide mortality. According to the World Health Organization (WHO), 17 million people died from CVD in 2011, and this number is expected to rise to 23.6 million by 2030. Many CVD risk factors, such as poor diet and sedentary lifestyles, often begin in childhood and adolescence and can continue into adulthood.

Although they are more frequently linked to adults, cardiovascular diseases (CVD) can also strike adolescents and teenagers. Although many people believe that heart disease is a “problem for adults,” heart disorders can affect children at birth as well as they get older. Whether inherited or acquired, these illnesses can have a serious negative effect on a child’s life if they are not detected and treated at an early age. Promoting early identification and efficient treatment of CVD requires an understanding of how the disease affects kids and teenagers.


Key Risk Factors for CVD

  1. Modifiable Factors
    Several lifestyle choices increase the risk of developing CVD, including: Poor diet (rich in saturated fats, cholesterol, salt, and sugar); Lack of physical activity (sedentary lifestyle); Stress; Alcohol consumption and; Smoking. 
  2. Non-Modifiable Factor
    Heredity (genetic factors) is the only risk factor that cannot be changed.

Impact of Obesity and Associated Conditions
Obesity, particularly in children, is a global concern. It is linked to conditions such as hypertension, diabetes, and dyslipidaemia, which increase the likelihood of developing CVD later in life. Obese children with comorbidities (like high blood pressure and metabolic syndrome) are more at risk for CVD in adulthood.

Preventive Measures
Regular physical activity can significantly reduce the risks of developing glucose intolerance, hypertension, high cholesterol, and stress-related issues, lowering the chances of CVD. Limiting alcohol consumption and avoiding tobacco use are also crucial for heart health.

Cardiovascular Disease Types in Adolescents and Children

Congenital heart abnormalities are the most frequent type of cardiovascular disease in children. These are congenital malformations, or structural issues with the heart, such as holes in the heart (septal defects), misformed heart valves, faulty heart valve formation, or problems with blood arteries. The severity of congenital cardiac abnormalities varies; some may need surgery at a young age, while others may be treated with medicine or lifestyle changes.

Acquired heart disorders are a subset of CVD that manifest after birth. These include ailments like myocarditis, an inflammation of the heart muscle that is frequently brought on by a viral infection, and Kawasaki disease, a sickness that causes inflammation of blood vessels. Another acquired heart disorder that can cause long-term harm to the heart if left untreated is rheumatic heart disease, which is a consequence of untreated strep throat or scarlet fever.

Children who have a genetic susceptibility, a family history of cardiovascular disease, and certain lifestyle variables are more likely to develop cardiovascular problems.

Early intervention for cardiovascular illnesses in children requires an understanding of their symptoms. Fatigue, fast breathing, chest pain, light-headedness, and fainting episodes are typical symptoms. In addition to poor growth and feeding difficulties, children with cardiac issues may also have cyanosis, or bluish skin, lips, or fingernails.

It is crucial to get a diagnosis as soon as possible because many cardiac diseases can worsen silently. Frequent check-ups enable the monitoring of cardiac function and can identify possible issues before they worsen.

Therapy and Administration

The kind and degree of a child’s cardiovascular disease determine how the illness is managed and treated. Medical interventions can include changes in lifestyle to support heart health, medicines that manage symptoms or reduce the risk of consequences, and surgery to correct heart abnormalities. To properly manage their illness, some youngsters could need lifelong observation and care.

Children’s cardiovascular illnesses are best managed with regular heart exams. These examinations give medical professionals the chance to keep an eye on a child’s cardiac health, monitor the effectiveness of any therapies, and make any necessary adjustments. To reduce the chance of developing new issues, preventive care is also crucial. Examples of this include promoting a diet low in fat, frequent exercise, and weight control.

The factors leading to CVD often begin early in life and progress into adulthood, with heredity being the only unchangeable risk factor. Recognizing the socioeconomic and clinical factors influencing children and adolescents can help shape targeted interventions. These efforts would aim to promote healthier lifestyle habits and prevent CVD from developing later in life. It is imperative for parents to recognise the early indicators of cardiovascular disease in their children and take proactive measures to schedule routine examinations. Although, children’s cardiac disorders can have a profound impact on their lives, but with early detection and appropriate care, these conditions can be properly managed, and the children can go on to lead happy, healthy lives. Making heart health a priority from a young age is a big step in the direction of a healthy future.
