OBJECTIVE: As mood disorders and obesity are interrelated, and both are linked to increased morbidity and mortality, risk factors for obesity should be identified and closely monitored in patients with bipolar disorder (BD). The aim of this study was to determine the diet quality of BD patients and to investigate its putative associations with comorbid obesity and disorders of carbohydrate metabolism, as well as the relationship between diet and clinical features of BD. PATIENTS AND METHODS: Eating patterns in 113 euthymic BD patients and 160 healthy control subjects were assessed using data obtained from a food frequency questionnaire. Associations of diet quality with subjects' weight, waist circumference (WC), insulin resistance index and clinical features of BD were also analyzed. RESULTS: BD patients had lower Mediterranean Diet Score than controls. Using principal analysis, four dietary patterns were revealed in the BD group (western-type, pro-healthy carbohydrates, unhealthy snacks, and meats and potatoes). Over 70% of patients with BD had Body Mass Index above 25kg/m2. The values of Fasting Triglycerides Glucose Index and WC were significantly higher in BD patients than in the control group. No significant association between diet quality indices and the clinical course of BD was found. CONCLUSIONS: In our work, euthymic bipolar patients showed unhealthy dietary patterns and had lower adherence to the Mediterranean diet than the controls. Increased values of insulin resistance indicators in the BD group point to the necessity of monitoring glucose and triglycerides levels and measurement of waist circumference in bipolar patients in the routine clinical practice. The cooperation between psychiatrists, dieticians and other medical professionals are necessary to develop dietary recommendations for patients with bipolar disorder. [ABSTRACT FROM AUTHOR]

OBJECTIVE: Due to the growing aging of societies an increasingly large group of people suffers from age-related impairment of cognitive functions and thus reducing the quality of life of the elderly. The purpose of the study was to evaluate the efficiency of cognitive functions in a group of aging residents of rural areas. PATIENTS AND METHODS: The inhabitants of a rural area were recruited and assessed: cognitive function as well as intellectual and physical activity, number of years of education, presence of diseases, using stimulants, diet, sources of living, marital status and family situation Subjects were divided into two groups: persons above 65 and older, constituting the studied group and persons between 40 and 64 years of age, constituting the control group. Both groups did not significantly differ in terms of sex or years of education. RESULTS: Statistically significant differences (p < 0.05) were found in the results of the tests concerning such functions as the sight recognition memory and spatial recognition memory, spatial operating memory both on the strategy level and on the level of committed errors. An analysis of the results obtained in the group of elderly people did not indicate any major differences between men and women as regards the analyzed cognitive functions, no statistically significant differences were found in cognitive testing depending on the number of years of education. The studied persons included in the physically active group scored better in the visual memory and learning tests. CONCLUSIONS: The conducted studies elucidated the dependence of the level of cognitive functions on age, a positive impact of physical activity on some cognitive functions, however we could not find differences between the efficiency of those functions and education, sex, presence of somatic diseases and activity of persons aged > 65.

OBJECTIVE: Last few decades have witnessed rapid ageing of the population. The prevalence of mild cognitive impairment and dementia is significantly higher in people aged 60 and over than in younger. The aim of the study was the assessment of the putative associations between physical activity and cognitive functioning in elderly inhabitants of a rural area. PATIENTS AND METHODS: The participants underwent physical assessment, physical activity, cognitive functions, depression were assessed. RESULTS: Highly active participants had better results in tests assessing psychomotor speed and in measuring attention and its flexibility comparing to groups of medium and low physical activity. Active people made fewer errors in the test measuring visual memory and new learning, and had significantly better results in the spatial-recognition memory test. Persons with symptoms of depression performed worse in visuospatial memory and working memory tests. Associations between physical activity and cognitive test results as well as association between body mass index and blood pressure and cognitive performance were observed. CONCLUSIONS: The results of the study suggest an association between higher physical activity and better cognitive functioning in the field of working memory and visual and spatial-recognition, attention and attention flexibility. Symptoms of depression, hypertension and increased BMI may adversely affect cognitive performance in elderly. [ABSTRACT FROM AUTHOR]

OBJECTIVE: In European countries more than 50% of the population are overweight, 30% with obesity. In Poland overweight was present in 41% of men and 28.7% of women (obesity 15.7% and 19.9%). It was examined whether obesity affects serum levels of brain-derived neurotrophic factor (BDNF) and interleukin-6 (IL-6), which may lead to the consequences of obesity, such as type 2 diabetes, hypertension, and finally the metabolic syndrome. We aimed to examine whether obesity affects the serum levels of BDNF and IL-6. PATIENTS AND METHODS: The study involved 144 people aged 45 to 86 years, 80 subjects with diagnosed obesity and 64 with normal body weight, ≤ 65 years old (n = 45) and > 65 years old (n = 99). All patients underwent tests of glucose, total cholesterol, HDL, LDL, triglycerides levels, using routine laboratory methods. A test of the concentration of IL-6 and BDNF was carried out. The declared level of physical activity (gymnastics, cycling or walking) was considered. RESULTS: It was shown that in women ≤ 65 years old, obesity was associated with higher levels of interleukin-6. When the test group, divided into the above categories, was analyzed for the diagnosis of hypertension, heart failure or diabetes mellitus, no statistically significant differences in the investigated parameters were detected. The concentration of brain-derived neurotrophic factor did not differ in the investigated subjects, regardless of sex, age, obesity, or the declared physical activity. CONCLUSIONS: The concentration of interleukin-6 in younger people, including those with normal body weight, correlated with total cholesterol and triglyceride levels, and it was significantly higher in obese women compared to those with normal body weight.
