Children Genetically Predisposed: The Added Perspectives


Lipid profile in children aged 5 to 15 years with parental history of ischemic heart disease (IHD) hypertension (HT) an diabetes mellitus (DM)(1) makes an interesting and serious reading. The subjects methods and the results have certain added perspectives which need further discussion.

(a) Not merely DM, but even HT and IHD may be found in both parents of a child under consideration. Moreover, these three diseases may not exist in isolation since HT contributes and predisposes to IHD while DM to HT and IHD both. At certain time one disease is manifest while another is occult.

(b) Genetic profile when clubbed with ‘environmental’ factors like diet, stress, lifestyle, obesity, indoor and outdoor work and exercise results generally in disease. Life style of children also implies sedentary habits like passion for TV and video games and even the lack of sports. Purely on genetic basis, risk of diabetes in children of one diabetic parent and both parents diabetic is 1 in 8 and 1 in 4 respectively. DM and HT are moreover examples of psychosomatic and stress disorders and likewise, to certain extent, IHD to stress. Puberty and adolescence is an explosive phase in life given all sorts of stress. We already know now how DM affects young Indians given the life styles and particular food habits not merely of carbohydrates but fats as well. The data of 11 children out of 75 with genetic profile of either parent diseased shows that these 11 children between 14-15 years had no difference in the HDL-c levels as compared to controls. This is significant under the higher HDL-c in children below 14 years. This further focuses our attention on adolescent phase since HDL-c has a protective function against HT and IHD in their future life.

(c) Fortunately, serum triglycerides like aminoacids form a metabolic pool, to which additions and eliminations are constantly being made during healthy active life. Ways of reducing triglycerides include indoor and outdoor work and exercise appropriate for age, situations and life style. This conscious effort augmented by training is being increasingly neglected during school life and at home under the increasing burden of study and the knowledge explosion and fierce competition even among school children now. This study excludes obese children, otherwise results would have been different.

(d) It is heartening to note from this study that high serum total cholesterol, HDL-c and triglycerides do not have predilection for female children since otherwise these considerations would have worrisome dimensions during their pregnancy and child birth in future.

(e) The authors have mentioned that the parents of these 75 children out of 100 had one of the diseases IHD, HT & DM for longer than 5 years without stating exactly how long and the stakes are higher longer the duration. Chronic disease is a higher risk factor considering the generally higher age of marriage possibly of such parents hence the higher age at which parenthood begins. This is significant for family and community too. Possibly lipid profile of children with more chronic disease(s) of parents would be different.

Viscosity of blood increases particularly under high lipoprotein Lp(a) factor and this is even worse than the risk with LDL-c. Indians have one of the highest levels of Lp(a) world over next only to Africans which, combined with high LDL-c and triglycerides levels results in high cardiovascular morbidity and mortality. A separate study on similar lines with incorporation of Lp(a) as extra high risk factor is worthwhile.
