Abstract
OBJECTIVE
Obesity is a serious public health problem associated with excessive food intake. Regulation of food intake in highly organized organisms is under the control of a large number of orexigenic and anorexigenic molecules. Therefore, the main purpose of this study has been to determine the relationship between obesity and some of the circulating orexigenic and anorexigenic peptides that have a role in appetite control and to determine whether the concentrations of these molecules differ according to blood groups.
PATIENTS AND METHODS
The study included 400 individuals of whom 100 were obese women, 100 obese men, 100 healthy men and 100 healthy women. Obese women and men were divided into 4 groups, according to their blood groups. In the control group, healthy women and healthy men were similarly divided into 4 blood groups. Each blood group within the groups, therefore, had 25 participants.
RESULTS
When leptin, nesfatin-1, obestatin and neuropeptide-Y, ghrelin and galanin levels of the control group and obese participants were compared, regardless of blood groups, leptin, nesfatin-1, obestatin and neuropeptide-Y were significantly higher, whereas only the ghrelin levels were significantly lower in obese patients. When the amounts of these hormones were measured according to gender, the situation was similar. When leptin, nesfatin-1, obestatin and neuropeptide-Y values of the control and obese participants' blood groups were compared with each other; these hormones were high in all blood groups; however, leptin levels in A blood group, nesfatin-1 levels in AB and O blood group, obestatin levels in AB blood group, neuropeptide-Y levels in A, B, AB blood groups were significantly higher. When the ghrelin levels of the blood groups in the control group and obese participants were compared, it was only significantly lower in the AB blood group. The ghrelin levels in the other blood groups of the obese individuals were again low, but not significantly so. When the distribution of hormones according to gender was evaluated, a situation parallel to the above results was recorded.
CONCLUSIONS
Leptin, nesfatin-1, obestatin and neuropeptide-Y and galanin levels of obese individuals were significantly higher than the control values, whereas the ghrelin values were significantly lower regardless of blood groups. Also, these hormones in blood partly varied with ABO blood groups. These different concentrations of hormones in ABO blood groups might be related with stimulation or suppression of appetite in human. However, further studies in other ethnic groups are needed to confirm these results.
