Abstract

Background

In recent years, there has been a sharp rise in the prevalence of obesity in adolescents . Numerous micronutrients, including magnesium, are deficient in obese people. Magnesium is a vital cofactor for hundreds of enzyme systems and is involved in the metabolism of sugars, proteins, and lipids. Obesity is one of the most significant risk factors associated with the development of glucose intolerance, cardiovascular disease, high blood pressure, and hyperlipidemia. This study aimed to compare serum magnesium and blood sugar levels between obese and normal-weight adolescents.

Methods

In this case-control study, fifty-seven 12-18-year-old obese and overweight adolescents (BMI above 85% as the case group) or normal-weight adolescents (BMI between 65% and 85% as the control group) were selected randomly from high schools across Birjand. Upon recruitment and assignment of participants, blood samples were collected and serum magnesium and glucose levels were measured. SPSS 15 software was utilized to analyze the collected data.

Results

Age and gender distributions were similar between the case and control groups (P> 0.05). The mean serum magnesium concentration was significantly lower in the case group than in the control group (P <0.05). The mean blood sugar level in the case group was significantly higher than in the control group (P <0.05). There was no correlation between blood glucose and magnesium in the two groups (P> 0.05).

Conclusion

The mean serum magnesium concentration of overweight and obese adolescents is lower than that of children of normal weight. Further research is required to evaluate the precise role of magnesium in obesity prevention and to establish the causal relationship between obesity and magnesium deficiency.
