Bottom line: Exercise works
The increasing rates of overweight and obesity in children in the United States have “significant downstream consequences that include increased risk of metabolic disease, including diabetes and hypertension, as well as increased rates of anxiety and depression,” Neil Skolnik, MD, professor of family and community medicine at the Sidney Kimmel Medical College of Thomas Jefferson University, Philadelphia, said in an interview.
Therefore, the effect of interventions such as exercise training on outcomes is important, he said.
The current study findings are “what you would hope for and expect – improvement in cardiometabolic parameters and fitness,” said Dr. Skolnik. “It was encouraging to see the effect of this relatively short duration of intervention has a clear positive effect on weight, BMI, and cardiometabolic parameters,” he said. “The real benefit, of course, comes from sustaining these habits over a long period of time.”
The lack of improvement in mental health is not surprising given the small study population “who did not have a high rate of mental health problems to begin with,” Dr. Skolnik added.
Barriers to promoting exercise programs for obese and overweight children in primary care are many, Dr. Skolnik said, including “having the motivation and funding to create programs like this so they are readily available to youth.”
However, the key message from the current study is simple and straightforward, according to Dr. Skolnik. “Exercise works! It works to improve fitness, cardiometabolic parameters, and weight control,” he said.
“There is always room for more research,” Dr. Skolnik added. The questions now are not about whether exercise benefits health; they are about figuring out how to implement the known benefits of exercise into daily living for all children, athletes and nonathletes alike, he said. “We need to find nonjudgmental ways to encourage exercise as a part of routine daily healthy living, up there with brushing teeth every day,” he emphasized.
The study was supported by grants from the Spanish Ministry of Economy and Competitiveness and El Fondo Europeo de Desarrollo Regional (FEDER) and by the MCIN (Ministerio de Ciencia e Innovación) / AEI (Agencia Estatal de Investigación. The researchers and Dr. Skolnik had no financial conflicts to disclose. Dr. Skolnik serves on the editorial advisory board of Family Practice News.
