Child obesity grows tenfold since 1975: study
Child obesity grows tenfold since 1975: study
Warning of a “double burden” of malnutrition, researchers said the rate of increase in obesity far outstripped the decline in under-nutrition.
“If post-2000 trends continue, child and adolescent obesity is expected to surpass moderate and severe underweight by 2022,” researchers wrote in The Lancet medical journal.
The team found that there were 74 million obese boys aged 5-19 in 2016, up from six million four decades earlier.
For girls, the tally swelled from five million to 50 million.
By comparison, there were 117 million underweight boys and 75 million underweight girls last year after the number peaked around the year 2000, the study said.
Almost two thirds of the underweight children lived in south Asia.
Obesity ballooned in every region in the world, while the number of underweight children slowly decreased everywhere except south and southeast Asia, and central, east and west Africa.
The prevalence of underweight children decreased from 9.2 percent to 8.4 percent of girls aged 5-19 over the study period, and from 14.8 percent to 12.4 percent in boys.
Obesity grew from 0.7 percent to 5.6 percent among girls and from 0.9 percent to 7.8 percent in boys.
In Nauru, the Cook Islands and Palau, more than 30 percent of children and teenagers were obese in 2016.
In some countries in Polynesia and Micronesia, the Middle East, North Africa, the Caribbean and the United States, more than one in five children were obese.
Experts divide people into body mass categories calculated on the basis of their weight-to-height ratio. These range from underweight, normal weight, overweight and three categories of obese.
Obesity comes with the risk of chronic diseases such as diabetes, while underweight children are more at risk from infectious diseases.
Children in either category can be stunted if their diet does not include healthy nutrients.
“There is a continued need for policies that enhance food security in low-income countries and households, especially in south Asia,” said study author Majid Ezzati from Imperial College London.
“But our data also shows that the transition from underweight to overweight and obesity can happen quickly in an unhealthy nutritional transition with an increase in nutrient-poor, energy-dense foods.”
The team used the height and weight data of 129 million people older than five to estimate body mass trends for 200 countries from 1975 to 2016.
While obesity in children and teens appears to have plateaued in rich countries, its rise continued in low- and middle-income countries, they found.
“Very few policies and programs attempt to make healthy foods such as whole grains and fresh fruits and vegetables affordable to poor families,” Ezzati said in a statement.
“Unaffordability of healthy food options to the poor can lead to social inequalities in obesity, and limit how much we can reduce its burden.”
Take a healthy approach to the issue of nutritional supplements
JEDDAH: There is a growing need for dietary supplements in Saudi Arabia, given the increasing popularity of junk food and the effective role supplements can play in treating diseases caused by mineral and vitamin deficiencies.
A recent study found that 22 percent of Saudi people take nutritional supplements. It is no surprise, then, that many Saudi businesses have forged partnerships with international dietary-supplement companies.
Dr. Rowaidah Idriss, a Saudi dietitian with a Ph.D. in nutrition, said dietary supplements can be defined as substances that provide the human body with a nutrient missing from a person’s regular diet. However, she stressed that they are not intended to replace healthy eating.
She also warned against taking them without first talking to a doctor or dietitian, as some products can have side effects, especially if taken before surgery or with other medicines.
“They can also cause problems if someone has a history of certain health issues,” she added.
A blood test can determine which nutrients we are not getting enough of in our diet, and therefore which supplements might be beneficial. Nutritional supplements are also used to help treat certain health conditions.
“Vitamin C, for example, is often used to reduce cold symptoms,” said Idriss. “Fish oil is taken to lower elevated blood triglycerides.”
She suggested four daily essentials that can bridge nutritional gaps in our diet: a multivitamin, vitamin D, calcium and omega-3 fatty acids.
“I routinely recommend a daily multivitamin and mineral supplement to my clients after consulting with their doctors,” she said.
“For menstruating women, who require 18 milligrams of iron each day, a daily supplement helps boost iron intake.”
She said people over the age of 50 are advised to take a multivitamin to ensure they are getting enough B12, which plays a key role in the functioning of the nervous system and the development of red blood cells.
“Older adults are more vulnerable to B12 deficiency because they are more likely to have decreased production of stomach acid, which is needed to release B12 from the proteins in food.” said Idriss.
“It is also a good idea to take a daily multivitamin if one is following a low-calorie diet.”
She also pointed out that a high intake of DHA and EPA, the two omega-3 fatty acids found in fish oil, are linked with a lower risk of heart disease and Type 2 diabetes. A deficiency of DHA might also increase the risk of Alzheimer’s.
“A daily intake of 1,000 milligrams of both DHA and EPA is equivalent to eating 12 ounces of salmon a week,” said Idriss.
The dietitian believes that the Saudis who take food supplements often do so more to benefit their appearance than their health.
“Saudi women consume more dietary supplements than other people in Saudi Arabia,” she said.
“They do so either to lose weight or to care for their hair and nails. Bodybuilders also take large amounts of supplements.”
However, both groups, according to Idriss, tend to take supplements on the recommendation of friends and trainers, not doctors.
She warned that commercials and social-media rumors can persuade people to buy supplements online that may not be approved as safe by the Saudi Food and Drug Authority, and advised people to get as much of their daily nutrient needs as possible from healthy eating.
“Along with vitamins and minerals, a healthy diet provides fiber and hundreds of protective phytochemicals, something a supplement cannot do,” she said, adding that the body absorbs natural food more effectively than supplements.
In addition, combining supplements with medications can have dangerous, even life-threatening, effects.
“Drugs for heart disease and depression, treatments for organ transplants, and birth-control pills are less effective when taken with herbal supplements,” she said.
“Taking an anticoagulant, aspirin, and a vitamin E supplement together may increase the potential for internal bleeding or even stroke.”
With the spread of fast-food restaurants and their alluring ads, the long-term health of the Saudi people is in danger, as children and young people snub natural sources of nutrients, such as fruit and vegetables.
“This can lead to many deficiency diseases. Moreover, vegetarians can develop similar illnesses due to the absence of meat in their diet,” she said.
Dr. Ashraf Ameer, a family-medicine consultant, said the importance of nutritional supplements lies in treating mineral and vitamin deficiency, especially for pregnant women, growing children, diabetics, people with chronic diseases, and the elderly.
“However, these products should come from reliable companies and meet Saudi food and drug requirements,”he added.
Mohammed Yaseen, who has a food supplements business, said his company works with a leading British health-care company to provide the Saudi market with high quality products.
“With this we hope we can contribute to the national transformation program by raising private-sector spending in health care from 25 percent to 35 percent, which in turn would lead to the sector’s financial sustainability and boost economic and social development in the Kingdom,” Yaseen said.
