The effect of educational and encouraging interventions on anthropometric characteristics and perilipin-1 levels:...

Perilipin protein located in lipid droplets is involved in formation and storage of lipid in adipocytes; thus, it is considered as one of the obesity biomarkers. This study was performed to examine the effect of educational and encouragement interventions and lifestyle modifications on anthropometric characteristics and perilipin-1 level.

This quasi-experimental study was conducted on subsample of TABASSOM Study. Participants were 42 overweight and obese children and adolescents aged 6-18 years old and 80 overweight and obese adults aged 19-65 years old. Anthropometric characteristics including weight, height, waist circumference (WC), body fat percentage (BFP), and perilipin-1 level were measured at the first and the end of study (after one year).

After intervention, the mean of perilipin-1 decreased significantly in total children and adolescents (before vs. after: 26.79 ± 13.17 vs. 22.57 ± 8.03; P = 0.006) and girls (27.75 ± 10.51 vs. 22.00 ± 8.15; P = 0.001), but decreasing was not significant in boys. In adults, perilipin-1 levels were significantly reduced in total subjects (before vs. after: 16.19 ± 13.42 vs. 15.34 ± 11.25; P = 0.029) and men (18.02 ± 15.78 vs. 15.44 ± 10.61; P = 0.003). There was no significant difference in mean of body mass index (BMI), WC, and BFP in both groups after 12 months.

Educational and encouraging interventions and lifestyle modifications could lead to decreasing perilipin-1 level in adults, children, and adolescents.
