Type 2 diabetes increases risk for obesity among subsequent generations

Area of Science:

• Pediatric Endocrinology
• Metabolic Disorders
• Public Health

Background:

• Childhood obesity is a growing global concern, with emerging prevalence in affluent urban Indian children.
• Limited data exists on the clinical profile of obese Indian children.
• This study aimed to characterize obese and overweight children and adolescents in India.

Purpose of the Study:

• To assess the clinical profile of overweight and obese children and adolescents presenting to a tertiary-care hospital.
• To identify associated metabolic and clinical conditions in this population.
• To explore potential risk factors, including familial history of diabetes mellitus.

Main Methods:

• A cohort of 109 children and adolescents (5-18 years) with overweight or obesity was recruited.
• Participants underwent comprehensive assessments: medical history, physical examination, blood tests (hemogram, liver function, glucose tolerance, insulin), and body fat estimation.
• Data was compared to healthy lean controls where applicable.

Main Results:

• The study included 70 boys and 39 girls; 73 were obese and 33 were overweight.
• Significant comorbidities were observed: 25% had hypertension, 44% had dyslipidemia, and 25% had abnormal glucose tolerance.
• Elevated plasma insulin levels were noted, and 75 children had a family history of diabetes mellitus (parents/grandparents).

Conclusions:

• Children with a family history of diabetes mellitus are at increased risk for developing obesity.
• Hyperinsulinemia may play a role in promoting obesity by influencing behavior and lifestyle.
• Early identification and intervention are crucial for at-risk populations.
