The effect of dietary intervention and physical activities on the lipid profile of obese children
Abstract
Background Obesity is defined as body weight increase due toexcessive fat accumulation. Obesity during childhood and teenage
years is related to cardiovascular risks including hyperinsulinism,
hypercholesterolemia, decreased high density lipoprotein (HOI),
and hypertension. The principles of managing obesity are reducing
energy intake and increasing energy use, e.g., by increasing physical
activities, changing life habits and, most importantly by involving
family in the therapeutic process.
Objective To evaluate the effect of dietary intervention and
physical activity on obese children.
Methods Seventy-six obese primary school children were
randomly allocated to either receive intervention (diet and
physical activities) or no intervention. At the beginning of the
study, lipid profile was measured in all subjects. Subjects in the
intervention group were asked to reduce calorie intake by 200 -
500 kCal per day, and participating in a walk of 20-30 minutes for
five days per week over a period of one month. After one month,
the lipid profile of both groups was remeasured and compared.
Results After one month, 7 3 children had successfully completed
the study and had complete data for analysis. There was a
significant change in the mean HOL level before intervention
(47.3 [SO 36.2] mg/dl) compared with after intervention (100.5
[SO 35.7] mg/dl, P<0.05) in the group where intervention was
implemented.
Conclusion There are no significant differences in serum lipid
values after intervention in both groups.
