Abstract
Survey of 1057 children (both sexes) aged 10-15 yrs from HIG, MIG and LIG was done to study the factors affecting prevalence of obesity and its association with dyslipidemia. Data was collected by using personal interview schedule on anthropometry (height, weight and BMI), dietary (24 hr recall method), education performance, physical activity pattern etc. Blood lipid profile and total body fat percent was done of sub-sample. BMI was calculated from weight and height and prevalence of obesity was determined. Mean ± SE of weight for HIG, MIG and LIG girls 10+ yrs was 35.34±4.93, 33.12±5.36 and 30.53±3.63; 11+ yrs 37.51±7.37, 33.54±5.22 and 31.0±4.30; 12+ yrs 39.74±5.87, 39.0±7.07 and 36.29±2.27; 13+ yrs 43.85±5.77, 41.46±7.73 and 40.33±3.63; 14+ yrs 50.29±4.90, 48.70±7.15 and 46.3±4.69 and 15+ yrs 52.05±9.09, 49.56±7.67 and 46.97±3.90 respectively. Similarly weight of boys was 10+ yrs 35.34±4.93, 33.12±5.36 and 30.53±3.63; 11+ yrs 37.51±7.37, 33.54±5.22 and 31.0±4.30; 12+ yrs 39.74±5.87, 39.0±7.07 and 36.29±2.27; 13+ yrs 43.85±5.77, 41.46±7.73 and 40.33±3.63; 14+ yrs 50.29±4.90, 48.70±7.15 and 46.3±4.69 and 15+ yrs 52.05±9.09, 49.56±7.67 and 46.97±3.90 respectively. Prevalence of obesity in HIG was 4.81, MIG 2.75 and LIG 1.05 per thousand children. Nutrient intake as compared to RDA by 10-12 yrs and 13-15 yrs obese girls and boys was energy 126% , 114% & 146% ,131%, protein 111.54% , 126.12% & 160%, 120%, total fat 245.1 %, 285.2% & 291%, 284% , thiamine 149% , 133.1% & 117%, 118%, riboflavin 141% ,134% & 119%,112%, Vitamin B12 143% ,102% & 145%, 135% ascorbic acid 114.95 , 108% & 159%, 155% iron 94.36%, 96% & 111% , 92% and calcium 110% , 96% & 113%, 103% respectively. Blood lipid profile of obese and nonobese children was blood glucose 111.50±1.00 & 88.20±1.83, TG 92.90±3.77 &77.50±3.40, total cholesterol 184.80±5.84 & 146.40±6.19 , HDL cholesterol 34.00±1.75 & 48.60±1.10 and LDL cholesterol 160.80±5.41 & 77.56±7.02. Fast food consumption, total fat intake, less physical activity (more time spent on T.V viewing), less participation in games, hereditary was found to be associated with the prevalence of obesity. Those children spent < 4hrs watching TV are more obese than, those watching > 4 hrs. Fat intake & weight was significantly positively correlated with total cholesterol & LDL cholesterol. Dyslipidemia and obesity was more associated in HIG children then MIG and LIG.
