The American Academy of Pediatrics is reported at its site, Healthy Children.Org in the study, Energy Drinks Can Harm Children:

Energy drinks may pose a risk for serious adverse health effects in some children, especially those with diabetes, seizures, cardiac abnormalities or mood and behavior disorders.
A new study, “Health Effects of Energy Drinks on Children, Adolescents, and Young Adults,” in the March issue of Pediatrics (published online Feb. 14), determined that energy drinks have no therapeutic benefit to children, and both the known and unknown properties of the ingredients, combined with reports of toxicity, may put some children at risk for adverse health events.
Youth account for half of the energy drink market, and according to surveys, 30 percent to 50 percent of adolescents report consuming energy drinks. Typically, energy drinks contain high levels of stimulants such as caffeine, taurine, and guarana, and safe consumption levels have not been established for most adolescents. Because energy drinks are frequently marketed to athletes and at-risk young adults, it is important for pediatric health care providers to screen for heavy use both alone and with alcohol, and to educate families and children at-risk for energy drink overdose, which can result in seizures, stroke and even sudden death.

Several deaths have been attributed to energy drinks.

The Washington Post reported in the article Energy drink popularity booms at college, despite health concerns:

A 2008 study of undergraduates at a large public university found that 39 percent of students had consumed at least one energy drink in the past month, with considerably higher rates for males and white students. The study, funded with a National Institute on Drug Abuse grant, noted that energy drink marketing tactics are “similar to those used to sell tobacco and alcohol to youths….”
Red Bull, which hit the country in the late 1990s, is credited with creating this industry using a Thai recipe. Today there are hundreds of energy drinks on the market, ranging from 1.93-ounce 5-Hour Energy shots to 32-ounce cans of Monster. Even Starbucks has gotten into the game, producing sparkling energy drinks and canned espresso beverages.
That proliferation has intensified debate about a long-standing question: Are energy drinks safe?
The focus of that question is often one of the main ingredients: caffeine. Energy drinks contain from 2.5 to 35.7 milligrams of caffeine per ounce; energy shots may have as much as 170 milligrams of caffeine per ounce, according to researchers. http://www.washingtonpost.com/local/education/energy-drink-popularity-booms-at-college-despite-health-concerns/2012/12/18/740e994e-45f8-11e2-8e70-e1993528222d_story.html

Alexandra Sifferlin reported in the Time article, Boys and Girls Are Impacted By Caffeine Differently:

New research shows even low doses of caffeine impact kids, and bodies of boys and girls react differently
Boys and girls’ bodies react differently to caffeine after they hit puberty, new research shows.
It’s established that caffeine consumption can increase blood pressure and lower heart rate in adults, and researchers from University at Buffalo in Buffalo, New York, have shown in the past that the same side effects happen in kids. This new research, published in the journal Pediatrics, found that the different ways caffeine affects males and females starts at puberty, with boys’ hearts more affected than girls’.
The researchers are unsure why exactly there are reaction differences—it could be due to hormones or other physiological factors—but it’s concerning since doses were low, at 1 and 2 mg/kg, and since caffeinated energy drinks are popular among kids and teens….
Currently, the FDA does not require the amount of caffeine in a product to be included on food labels. Since the FDA says caffeine is a natural chemical found in items like tea leaves and coffee beans, it’s regulated as an ingredient not a drug. Energy drinks are not regulated because they are sold as dietary supplements. A 2012 Consumer Reports review of 27 best-selling energy drinks found that 11 do not list caffeine content. Among those that do, the tested amount was on average 20% higher than what was on the label.
The FDA says 400 milligrams a day, about four or five cups of coffee, is generally not considered dangerous for adults. The American Academy of Pediatrics discourages caffeine consumption among young kids and adolescents.
The latest study did have weaknesses, since its study group was primarily among white, middle class, and well educated, and they could not completely confirm that control groups were totally abstinent when it came to consuming caffeine. Still, the research is important as medical and governmental groups take a closer look at how the stimulant may be impacting children’s health. http://time.com/2878504/boys-and-girls-are-impacted-by-caffeine-differently/

Abstract
BACKGROUND: Caffeine use is on the rise among children and adolescents. Previous studies from our laboratory reported gender differences in the effects of caffeine in adolescents. The purpose of this study was to test the hypotheses that gender differences in cardiovascular responses to caffeine emerge after puberty and that cardiovascular responses to caffeine differ across the phases of the menstrual cycle.
METHODS: To test these hypotheses, we examined heart rate and blood pressure before and after administration of placebo and 2 doses of caffeine (1 and 2 mg/kg) in prepubertal (8- to 9-year-olds; n = 52) and postpubertal (15- to 17-year-olds; n = 49) boys (n = 54) and girls (n = 47) by using a double-blind, placebo-controlled, dose-response design.
RESULTS: There was an interaction between gender and caffeine dose, with boys having a greater response to caffeine than girls. In addition, we found interactions between pubertal phase, gender, and caffeine dose, with gender differences present in postpubertal, but not in prepubertal, participants. Finally, we found differences in responses to caffeine across the menstrual cycle in postpubertal girls, with decreases in heart rate that were greater in the midfollicular phase and blood pressure increases that were greater in the midluteal phase of the menstrual cycle.
CONCLUSIONS: These data suggest that gender differences in response to caffeine emerge after puberty. Future research will determine the extent to which these gender differences are mediated by physiological factors, such as steroid hormones, or psychosocial factors, such as more autonomy and control over beverage purchases.

Here is the press release from the University of Buffalo:

Caffeine affects boys and girls differently after puberty, study finds
Jennifer Temple
“In this study, we were looking exclusively into the physical results of caffeine ingestion.”
Jennifer Temple, associate professor of exercise and nutrition science
University at Buffalo
BUFFALO, N.Y. – Caffeine intake by children and adolescents has been rising for decades, due in large part to the popularity of caffeinated sodas and energy drinks, which now are marketed to children as young as four. Despite this, there is little research on the effects of caffeine on young people.
One researcher who is conducting such investigations is Jennifer Temple, PhD, associate professor in the Department of Exercise and Nutrition Sciences, University at Buffalo School of Public Health and Health Professions.
Her new study finds that after puberty, boys and girls experience different heart rate and blood pressure changes after consuming caffeine. Girls also experience some differences in caffeine effect during their menstrual cycles.
The study, “Cardiovascular Responses to Caffeine by Gender and Pubertal Stage,” will be published online June 16 in the July 2014 edition of the journal Pediatrics.
Past studies, including those by this research team, have shown that caffeine increases blood pressure and decreases heart rate in children, teens and adults, including pre-adolescent boys and girls. The purpose here was to learn whether gender differences in cardiovascular responses to caffeine emerge after puberty and if those responses differ across phases of the menstrual cycle.
Temple says, “We found an interaction between gender and caffeine dose, with boys having a greater response to caffeine than girls, as well as interactions between pubertal phase, gender and caffeine dose, with gender differences present in post-pubertal, but not in pre-pubertal, participants.
“Finally,” she says, “we found differences in responses to caffeine across the menstrual cycle in post-pubertal girls, with decreases in heart rate that were greater in the mid-luteal phase and blood pressure increases that were greater in the mid-follicular phase of the menstrual cycle.
“In this study, we were looking exclusively into the physical results of caffeine ingestion,” she says.
Phases of the menstrual cycle, marked by changing levels of hormones, are the follicular phase, which begins on the first day of menstruation and ends with ovulation, and the luteal phase, which follows ovulation and is marked by significantly higher levels of progesterone than the previous phase.
Future research in this area will determine the extent to which gender differences are mediated by physiological factors such as steroid hormone level or by differences in patterns of caffeine use, caffeine use by peers or more autonomy and control over beverage purchases, Temple says.
This double-blind, placebo-controlled, dose-response study was funded by a grant from the National Institute on Drug Abuse of the National Institutes of Health.
It examined heart rate and blood pressure before and after administration of placebo and two doses of caffeine (1 and 2 mg/kg) in pre-pubertal (8- to 9-year-old; n = 52) and post-pubertal (15- to 17-year-old; n = 49) boys (n = 54) and girls (n = 47).

Because children are still growing and developing, caffeine affects their development.

Diet Health Club has some excellent information in the article, Caffeine and Teenagers:

Café shops have become a common place for teen’s hangout. But they don’t realize that they are just sitting with a cup of fat, sugar and caffeine, unless they choose skim milk instead of cream in their coffee.
Side effects of caffeine on teenagers
1. Caffeine when taken in moderate amounts can increase mental alertness. However when taken in higher doses, it can cause anxiety, headaches, moods, dizziness and may also interfere with normal sleep. Caffeine when taken in very high dose can be very harmful to the body.
2. Caffeine is addictive and if stopped abruptly can cause many withdrawal symptoms like headache, irritability, temporary depression and muscle ache.
3. Regular caffeine consumption can reduce caffeine sensitivity that means the caffeine required is higher to achieve the same effects. Thus more caffeine a teenager consumes the more will be its need to feel the same effects.
4. Caffeine is a diuretic it causes water loss from the body (through urination). Especially in summers caffeine is a very bad choice and it may cause dehydration.
5. Caffeine is not stored in the body and is passed through the urine, but if the person is sensitive to caffeine he/she might feel its effects up to six hours.
6. Caffeine when consumed in large amounts can cause loss of calcium and potassium from the body that can lead to sore muscles and delayed recovery time after any exercise.
7. Some teenagers may be unaware of the fact that caffeine in high amounts can cause nervous disorders and may also aggravate heart problems.
Try to cut down the caffeine in your diet gradually; moderation is the key (amounts less than 100 milligrams). Include healthy options like fresh fruit juices, water, milk, flavored seltzer, decaffeinated soda or tea instead of caffeinated beverages, soft drinks, sodas and other caffeine rich drinks. Make sure to read the nutritional fact labels for caffeine content before consuming the product. http://www.diethealthclub.com/caffeine/caffeine-and-teenagers.html

Children and teens should limit their caffeine intake.

Energy drinks may pose a danger

The American Academy of Pediatrics is reporting at its site, Healthy Children.Org in the study, Energy Drinks Can Harm Children

Energy drinks may pose a risk for serious adverse health effects in some children, especially those with diabetes, seizures, cardiac abnormalities or mood and behavior disorders.

As more young people consume energy drinks, more problems are occurring.

Daniel J. DeNoon of WebMD Health News reports in the article, More Deaths, Illness Linked to Energy Drinks which was reviewed by Louise Chang, MD reports:

Nov. 16, 2012 — The FDA has posted adverse-event reports for two more energy drinks: 40 illnesses and five deaths linked to Monster Energy, and 13 illnesses and two lasting disabilities linked to Rockstar Energy.

The new reports follow this week’s revelation of FDA reports linking 92 illnesses and 13 deaths to 5-Hour Energy shots. The FDA previously said it was investigating the deaths linked to Monster Energy.

These adverse-event reports (AERs) are filed by patients, families, or doctors. They simply warn that the products might have harmed someone — but they do not prove that the product caused harm. The FDA can remove a product from the market only when investigation shows that the product causes harm when used according to the product label.

“If we find a relationship between consumption of the product and harm, FDA will take appropriate action to reduce or eliminate the risk,”  FDA public information officer Shelly Burgess says.

Moreover, the reports do not offer details on any underlying medical conditions that may have led to product-related illnesses.

The reports, some dating back to 2004, are not a complete inventory of all events that product users may have suffered. Most people, and many doctors, do not know how to file these reports or do not get around to filing them. And even when a product actually causes an illness, a user or doctor may not associate the product with the illness.

The new reports detail the events suffered by users of 5-Hour, Monster, and Rockstar energy drinks. These include:

  • Deaths due to heart attack or suicide linked to 5-Hour Energy
  • A miscarriage linked to 5-Hour Energy
  • Convulsions, life-threatening fear, deafness, and hemorrhage linked to 5-Hour Energy
  • Deaths due to heart attack or loss of consciousness linked to Monster Energy drink
  • Hospitalization due to irregular heartbeat, severe diarrhea, migraine, psychotic disorder, heart attack, and/or vomiting linked to Monster Energy drink
  • Disability from irregular heartbeat or stroke linked to Rockstar Energy drink
  • Hospitalization due to psychotic disorder, increased heart rate, or loss of consciousness linked to Rockstar Energy drink

All of these reports are collected by the product manufacturers. Because they market their products as nutritional supplements, they are required to submit them to the FDA. http://www.webmd.com/diet/news/20121116/more-deaths-illness-energy-drinks

There are many reasons why people use energy drinks.

Barbara Aufiero reports in the Livestrong article, Why Do People Buy Energy Drinks?

Daytime Sleepiness

Many people depend on coffee to start their day. Caffeine boosts your energy and causes you to feel more alert and awake. Since these effects wear off after a few hours, you may experience a mid-afternoon lull shortly after lunch. Energy drinks can provide the extra oomph that you seek in order to get through your day. These energy drinks are often marketed towards young adults who have responsibilities in addition to work, such as family obligations, or aspirations to further their education.

Lack of Sleep

The regular use of energy drinks may be indicative of an underlying condition such as fatigue or insomnia, according to registered dietitian Kara Mitchell from Duke University. Fatigue is a symptom of a multitude of mental and physical health conditions. Fatigue caused by insomnia or lack of sleep is treatable. However, frequent use of energy drinks may mask the underlying condition. Energy drinks may also cause adverse health conditions such as irritability and high blood pressure, according to Mitchell.

Alcohol

The majority of energy drinks do not contain alcohol. Mixing alcohol with energy drinks is not uncommon among college students and young adults. The idea is that caffeine will reduce the sedative effects of alcohol and make you more alert. Researchers assessed the attention and reaction times of young adult drinkers between the ages of 21 and 30, after drinking energy drinks with alcohol. This study was published in the February 2011 issue of “Addiction,” and found an association between alcohol and impairments in attention and reaction. However, the addition of caffeine did not mitigate these impairments.

Increase Performance

Energy drinks and sports drinks, like Gatorade and Powerade, are not interchangeable. As such, they may be kept in separate aisles at supermarkets. Dr. Edward Laskowski of the Mayo Clinic suggests drinking water or sports drinks when you exercise, not energy drinks. One reason is that sports drinks replenish fluids and electrolytes, whereas energy drinks do not. Another reason is that the caffeine in energy drinks may cause restlessness, headaches, nausea and tremors. Excessive use is associated with chest pains, seizures, heart attack and even sudden cardiac death.

Whatever benefit there is to the use of energy drinks must be weighed against the risks which can be substantial for some individuals.
