Introduction. Obesity is today one of the most dangerous and the fastest growing civilization diseases in the world. The number of overweight or obese people is continually increasing. Obesity is defined as abnormal fat accumulation in an organism that may cause health impairment. Obesity may be conducive to an increased risk increase for occurrence of cardiovascular diseases as well as stroke, some types of cancer, endocrinal disorders, osteoarthritis and other bone disorders. Some studies have demonstrated that high body mass index (BMI) is protective against the development of osteoporosis and osteoporotic fractures in men and women. In slim people with a lower BMI than normal, weight loss is associated with low bone mineral density (BMD). On the other hand, obesity in childhood may lead to fragility fractures and may lead to early development of osteoporosis in adulthood. Currently, we have numerous methods for measurement of obesity such as dual-energy X-ray absorptiometry (DXA), bioelectrical impedance analysis (BIA), total body electrical conductivity (TOBEC) as well as magnetic resonance imaging (MRI) and computed tomography (CT). These methods are useful for diagnosing obesity and bone tissue disorders such as osteopenia with sarcopenia or osteoporosis, in particular in perimenopausal women and men after andropause. Aim of the study. The purpose of the study was review the literature on obesity and bone tissue disorders and their interrelations. Material and method. Analysis of literature.

The study catalogues all currently known finds of bone and antler harpoons and points associated with Paleolithic, Mesolithic and Protoneolithic culture in the southern Baltic zone, between the mouths of the Oder and Niemen rivers. It undertakes an analysis of the category in typological, chronological and cultural terms, taking into consideration results of recent paleogeographic investigations and research on the Stone Age in this region. An important element of this study are drawn plates of nearly all of the discussed objects as well as distribution maps. The author gives a critical analysis of the classic harpoon and point typology presented by J.G.D. Clark (1936) in the context of a broader source base, encompassing finds from the entire Baltic zone. A detailed morphological classification of harpoon barbs is one of the most important tools essential to this end.
