Serum cholesterol (total, low-density lipoprotein, and high-density lipoprotein cholesterol), triglyceride levels, and fat consumption among Jerusalem Arab and Jewish schoolchildren

Abstract

As part of initial health screening for the “Know Your Body” Program-based comprehensive health education program, 841 Jerusalem first- and second-grade schoolchildren were tested for total serum cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, and triglycerides. The same population, which included 643 Jewish (76.5%) and 198 Arab children (23.5%), had their nutritional habits evaluated by means of a parent-completed food-frequency questionnaire. Arab schoolchildren had significantly lower total, high-density lipoprotein, and low-density lipoprotein cholesterol levels and higher triglyceride levels than the Jewish children studied (total cholesterol: Arab mean, 153.1 mg/dl, Jewish mean, 170.3 mg/dl; high-density lipoprotein cholesterol: Arab mean, 46.4 mg/dl, Jewish mean, 48.5 mg/dl; low-density lipoprotein cholesterol: Arab mean, 90.7 mg/dl, Jewish mean, 108.5 mg/dl; triglycerides: Arab mean, 77.9 mg/dl, Jewish mean, 66.3 mg/dl). No significant differences in consumption level of foods high in saturated fats and/or cholesterol were found between populations, although the Arab children showed a tendency to eat more of these foods. Significant differences in total cholesterol values were also found among Jewish children of different origins, but no significant differences were found in consumption levels of saturated fats and cholesterol. Further studies are needed to determine the reasons for the differences in total cholesterol and lipoprotein levels found between Jewish and Arab schoolchildren.
