Relationship of actual nutrition and health of elderly and old age-6

Material analysis shows that in all groups there was a statistically significant relationship between the total amount of fat in the diet and in essential lipids in the blood serum. Between the total amount of fat and the level of hypercholesterolemia and letsitinemii were correlated, respectively, r = 0.82 and -0.74. This dependence is most clearly manifested in the value of the coefficient of lecithin / cholesterol: it was the most favorable at low levels of fat in the diet (1,04 ± 0,009) and least favorable — at high (0,97 ± 0,01). Note the presence of such a link, depending on the content in the diet of vegetable and animal fats failed.
The severity of atherosclerotic lesions of major vessels of the heart, the brain, consistent with the state of lipid exchange parameters characterizing the functional state of the cardiovascular system in the examinees. Noteworthy in this regard the relationship with different calorie integral evaluation of bioelectric processes in the heart (as the complex age-related changes). It was found that in the low-calorie food people with ECG changes are more common grade 0-1 (74.6%) than at high (53.9%). These results are fully consistent with those of some of the ECG. So, if I group the heart rate to 60 beats per minute was detected in 13% of older men, the III group — 58.2% (p <0.05). The pulse rate of over 70 per minute in group I was found in 39.2% of cases, whereas in the group-III at 22.5%, and so on, which indicates the most favorable chronotropic activity of the heart, most examinees with low-calorie diet.
The number of older people with the difference in performance between the actual and proper electrical systole to 0.02 s in group III was 70.2% in group I — 66.6%. At the same time the margin between Q-T = 0.05 and above as the elderly and old people most frequently detected in the I group.
Value of the total voltage of the T wave in standard and precordial ECG in older people is also related to caloric intake. Thus, while in Group I of its value to 17 mm were found in 49.4%. and up to 26 mm and above — in 19.1%, and in Group III -, respectively, in 49.7 and 29.6% of persons.
Less pronounced changes in systolic index identified in the examined groups II and III compared to I group. Thus, in the III group change its value to 10%, 10% or more were detected in 79.4 and 20.6% of the elderly, in the III group — respectively, 87.5 and 12.5%.
BCG analysis of data indicates that the changes BKG I-II degree (at Brown) were found in group II examined in 48.1%, and in Group I — in 36.3% of cases, changes in III-IV degree — at 63, 6 and 51.9%, respectively, in groups I and II.
Taking into account that the evaluation function with "state of the cardiovascular system would be incomplete without taking into account the elastic properties of the vascular wall, we analyzed the data of the surveyed arteriopezografii accommodating different caloric intake. It was found that in group I individuals with pulse wave velocity D 12 m / s or more of 10.4%, while in Group III — only 5.6%, the number of people with pulse wave velocity in the range of 7.6 D m / s was determined in inverse proportion, accounting for 8.7 and 14.3%.
Given the evidence in the literature (Ries, 1970; Gordon, Kennel, 1973, etc.) of the close connection of overweight people with the development of pathological changes in the body, we subjected the raw materials and the analysis in this regard. We proceed from the known locations of the excess weight the body has high requirements to the functional state of the cardiovascular system, promotes the development of hyperlipidemia, is a "risk factor" in the development of atherosclerosis, affects the nature of metabolism and so on (Fig. 22). The findings lead to the conclusion of the correlation between caloric intake and body weight in older people (r = + 0.88). and weight body in the elderly than in the old, and the ratio between height and weight greater in women than in men. With the increase in caloric intake weight the body of the surveyed increased. Given that the excess weight body usually has the alimentary nature (Burger, 1960; Ries, 1970), we can assume that observed changes of the cardiovascular system in older people due to the group I degenerative "changes in the system, since the latter is usually observed for obesity .

Site "Survival in the wild nature", glad to see you. If you come to us, it means you want to get complete information about survival in a variety of extreme conditions, in emergency situations. Man, throughout the development, sought to preserve and protect themselves from the various negative factors surrounding it - cold, heat, hunger, dangerous animals and insects.

Site structure "Survival in the wild nature" is simple and logical, selecting a specific section, you will find information. You will find on our website recommendations and practical advice on survival, unique descriptions and pictures of animals and plants, turn-based scheme to trap wild animals, tests and reviews of travel gear, rare books on survival and wildlife. The site also has a large section devoted to video on survival survivalist-known professionals around the world.

The main theme of the site, "Survival in the wild nature" - is to be ready to be in the wild, and the ability to survive in extreme conditions.

The Survival in the wild nature - how correctly to behave, it having appeared in an emergency situation. Ability to find a way out from any situation: to kindle a fire, to put traps, to prepare food, to arrange dwelling and a lodging for the night; to learn to knit knots, to clear water, to be guided by districts, correctly to choose equipment, a knife. Also you can download directories to tourists, encyclopedias survivals, video Bear Grills to Survive at any cost (Man vs. Wild).
