The short-term effects of an intervention programme on the modifications of plasma lipids in workers. The pilot study

The purpose of the pilot study was to determine the effectiveness of a medical intervention program in the reduction of plasma lipids in a group of hyperlipemic persons. Two groups were compared in this study over a one year period. The groups consisted of a group of hyperlipemic persons with TG levels greater than 150 mg% and a second group with plasma lipids within normal limits. The plasma lipids concerned in this study were cholesterol, triglycerides, and HDL-C. The group of hyperlipemic subjects received intense nutritional counselling while the normal subjects received only printed guidelines to normal healthy nutrition. The results of this study, confirm positive results obtained by other intervention programs. A substantial reduction in TG levels was observed in 37.7% of the hyperlipemic group while 14.1% of the normal group had considerable increases in their TG levels during this one year study period. The results of the serum lipid surveys proved the high interyear correlation for both HDL-C and TC, but a very much weak interyear correlation for TG.
