Childhood Obesity: 4 Out Of 10 Children Suffer From Foot And Leg Pain

A study by Spanish universities warns that 38% of overweight or obese children suffer from pain in their extremities, a direct consequence of the pressure their feet and legs bear at an early age.

Leg and foot pain has become a silent reality for thousands of children in Spain. A joint study by several universities and health centers reveals that more than a third of children between the ages of 9 and 12 who are obese or overweight experience discomfort in their lower extremities, a warning sign about the physical consequences of excess weight at an early age.

The study, conducted by the universities of Malaga, Seville, Valencia and the European University of Madrid, with support from the Virgen de la Victoria University Hospital and the Arroyo de la Miel Primary Care Centre (Malaga), shows compelling data: 27.3% of overweight children report pain in one or more areas of their legs, while 10.7% suffer discomfort exclusively in their feet.

Childhood obesity and musculoskeletal pain

Researchers note that obesity not only increases the risk of metabolic diseases, but is also a determining factor in musculoskeletal pain in children, with a higher prevalence of pain in multiple areas of the body rather than just one.

Pediatric podiatrist Elena García, a member of the COPOAN educational and sports initiative, explains that excess weight alters the structure of the foot, causing it to flatten and lose functionality. “ The ligaments and joints bear an excessive load, which causes progressive weakness and makes it difficult for the feet to perform their function properly,” she explains.

Consequences on children’s quality of life

This biomechanical deterioration translates into fatigue, discomfort when walking, and a reluctance to engage in physical activity. The specialist warns that poor foot function not only restricts mobility but also affects children’s self-esteem. Many children end up avoiding sports, opting for a sedentary lifestyle that perpetuates the cycle of childhood obesity .

Healthy habits and appropriate footwear are preventive keys

Prevention is possible. International studies, such as those conducted at the University of Potsdam (Germany) and the University of Applied Sciences, Health and Physiotherapy in Bern (Switzerland), highlight that maintaining a balanced diet, exercising regularly, and wearing appropriate footwear are essential measures for reducing foot and leg discomfort in childhood.

García recommends shoes with a wide last, good support, and a spacious toe box to promote internal muscle development. The sole, he adds, should be thin and flexible, so that the rapidly developing nervous system can enhance the foot’s functionality. He also insists that the heel counter should be nonexistent so that the ankle gains natural firmness.

In the case of athletic footwear, the specialist emphasizes that each discipline requires a tailored design, as running on asphalt is not the same as playing basketball on an indoor court.

Importance of early detection

Another preventative measure is performing a gait analysis at an early age, which allows for the detection of possible structural abnormalities and the anticipation of complications. Aspects such as posture, body weight distribution, and exercise practice are decisive factors in ensuring long-term foot health.

“Early detection, along with appropriate measures, allows children to enjoy an active life without limitations. Well-cared-for feet from childhood make a significant difference in overall physical well-being and help prevent future musculoskeletal problems,” García concludes.
