    Abstract:
    BACKGROUND: Malnutrition and bone disease are common in adults with chronic pancreatitis (CP). We studied the nutritional status and bone mineral density (BMD) of children with CP and the factors predicting them. METHODS: CP children were prospectively evaluated with a detailed questionnaire, anthropometry, 25-hydroxy vitamin D, fecal elastase and BMD [total body less head (TBLH), spine and hip] by dual energy x-ray absorptiometry. Body mass index (BMI) Z score of -1 to -1.9, -2 to -2.9 and <-3 was taken as mild, moderate and severe malnutrition respectively. Low BMD and osteoporosis were defined as per International Society for Clinical Densitometry. RESULTS: 83 children (46 boys, 14[4.3-21]years) with CP were enrolled. Majority had Cambridge IV (51,62.2%) or III (15,18.3%) changes. 34(41%) had undernutrition (mild-37.3%, moderate-2.4%, severe-1.2%). Overweight and obesity were present in 3.6% and 1.2% cases. BMI had a significant correlation with haemoglobin, serum albumin, percentage body fat and BMD. A majority had low fecal elastase (69 [84.1%], <100 μg/g) and vitamin D deficiency (70[84.3%],<20 ng/ml). 9 cases had a history of fractures. 14/75(18.6%) cases had low TBLH-BMD and this group had a lower BMI (-1.3[-1.9 to 0.34] vs 0.8 [-2.1 to 5.50; p = 0.03) than patients with normal BMD. There was no difference in age, disease duration, vitamin D, fecal elastase and Cambridge grade between normal and low BMD. CONCLUSIONS: 41% CP children have undernutrition with a majority having mild undernutrition. Nearly 20% have low BMD, with osteoporosis in none. Subjects with low BMI have lower BMD and percentage body fat.
