Prevalence of fatty pancreas and its relation with anthropometric values on the Growth and Obesity Cohort Study.

OBJECTIVE

Nonalcoholic Fatty Pancreas Disease (NAFPD) is characterized by excessive lipid accumulation within the pancreas in the absence of alcohol intake, potentially leading to pancreatic dysfunction and metabolic complications, including type 2 diabetes mellitus, acute and chronic pancreatitis, and pancreatic carcinoma. The authors aim to estimate the prevalence of NAFPD and its association with anthropometric parameters in a cohort of Chilean adolescents.

METHOD

The authors conducted a cross-sectional analysis of the "Growth and Obesity Chilean Cohort Study" (GOCS), a longitudinal study involving nearly 1000 children, followed yearly since 2006. All participants underwent anthropometric measurements and abdominal ultrasonography.

RESULTS

A total of 741 adolescents were included; 30 exhibited ultrasonography findings compatible with fatty pancreas (4 %). Adolescents with NAFPD had higher BMI z-score (2.33 (1.52-2.69) vs 0.67 (-0.2-1.4), p < 0.001), waist circumference (WC) (90.9 (81.53-98.58) vs 72.2 (67.55-79.83), p < 0.001), waist-to-height ratio (0.55 (0.48-0.6) vs 0.44 (0.41-0.49), p < 0.001), triponderal index (17.35 (15.14-19.25) vs 13.62 (12.07-15.54), p < 0.001), subcutaneous fat (32.4 (21.77-44.95) vs 16.2 (9.3 - 25.3), p < 0.001), visceral fat (45.15 (36.92-62.08) vs 35.5 (28.55-44.25), p < 0.001), systolic blood pressure (p = 0.009), and diastolic blood pressure but only in boys (p = 0.004) compared with controls. The prevalence of liver steatosis was significantly higher in the NAFPD group (63.3% vs 5.2 %, p < 0.001). After adjusting for sex and BMI, only the association with waist circumference and liver steatosis remains statistically significant.

CONCLUSION

In adolescents, NAFPD has a prevalence of 4 % and is associated with a higher BMI z-score, WC, superficial fat, and blood pressure levels. Liver steatosis exhibited a strong association with NAFPD.
