Introduction and objective: The developing brain of a child is extremely prone to damage resulting from exposure to harmful environmental factors, e.g. heavy metals. Intoxication of children’s organisms with lead and cadmium affects their intellectual development. Even a relatively small amount of this metal in children’s blood can lead to developmental dysfunctions. The aim of this study was to analyse the correlation between blood lead and cadmium levels in children with behaviour disorders and their functioning in the home. Material and methods: This survey-based study was conducted among 78 families with children diagnosed as having behaviour disorders. It was performed using the ADHD-Rating Scale-IV. To determine lead and cadmium levels the laboratory procedure was based on Stoppler and Brandt’s method. Results: The mean blood lead level was 19.71 μg/l and the mean blood cadmium level was 0.215μg/l. Higher blood lead levels in children correlates positively with incidences of hyperactive and impulsive behaviour in the home, as assessed by parents (p=0.048). Statistically significant effects of cadmium on children’s behaviour were not noticed. Conclusions: The effect of lead on the developing organism of a child has such behavioural consequences as attention disorders, hyperactivity and impulsive behaviour which, in turn, may interfere with children’s functioning in the home. A negative effect of cadmium on the functioning of children with behaviour disorders in the home was not proved.
Background: Lifestyle and health behaviours are determined by the level of knowledge, beliefs, existing dysfunctions, and interpersonal relationships, as well as personality factors. The aim of this study was to assess health behaviours undertaken by postmenopausal women, and to analyze how they are influenced by personality factors. Material/Method: The study included 196 postmenopausal women at the mean age of 56.80 +/- 4.08. The Health Behaviour Inventory and a personality questionnaire (NEO-FFI) were used. Results: In the study, women living in cities of over 100.000 residents scored higher than those living in smaller towns (p<0.05). The level of neuroticism negatively correlated with overall health behaviours, health practices, and a positive mental attitude (p<0.05). The level of conscientiousness negatively correlated with health behaviours, a positive mental attitude, and preventive behaviours (p<0.05). Positive correlations were observed between the level of extraversion and overall health behaviours, preventive behaviours, normal eating habits, health practices, and a positive mental attitude (p<0.05). Conclusions: 1. Raising the awareness through educational programmes implemented as part of care provided by primary care centres (especially in smaller towns and rural areas) could improve the level of healthful behaviours undertaken by postmenopausal women. 2. Health behaviours are also greatly dependent on personality traits, which are biologically determined and relatively stable.
Introduction and objective: The level of trace elements is extremely important for the maintenance of normal functioning of the human body. The risk of disturbance of their balance increases especially dynamically during the period of menopause. The objective of the study was the effect of MHT on the levels of bioelements (Mg and Zn) in blood plasma, and toxic metals (Pb and Cd) in the whole blood in postmenopausal women. Materials and methods: The study covered 323 women at postmenopausal age from the population of the West Pomeranian Region, in whom the levels of Mg, Zn, Pb and Cd were determined. The women were divided into two groups: study and control. The study group were 152 women who used menopausal hormone therapy (MHT). The control group were 171 women who did not use MHT, and had had their final menstrual period at least one year prior to inclusion in the study. The mean age of the women examined was 56±5. Results: Significantly higher levels of the bioelements Mg, Zn were observed in women who used MHT, compared to the control group (p<0.05). The concentration of Pb in whole blood was significantly lower in the study than the control group: 16.09±7.33 μg/l and 20.18±9.01 μg/l, respectively. An elevated level of Cd in whole blood was found in both groups of women: 0.9±1.03 μg/l and 0.8±1.1 μg/l, respectively. It was noted that women who used MHT more frequently declared the presence of climacteric symptoms (p<0.05). Conclusions: 1) Higher levels of Mg and Zn were found in blood plasma of women who used MHT. 2) The mean concentration of Cd in the blood of women in both groups was similar. 3) In women who use MHT the level of Pb in whole blood was lower, compared to the rest of the women.
Health behaviours are actions taken by a person in the field of health. Risky behaviours are those that pose a threat to health. Bioelements are essential for the proper functioning of every organism. Their trace amounts are necessary for life and health. The aim of this study was to determine the relationship between health behaviours and the levels of bioelements in the blood serum of secondary school students. This survey-based study was carried out on a sample of 376 secondary school students aged 13-16 years. It was performed using the HBSC questionnaire (Health Behaviour In School-aged Children: A WHO Collaborative Cross-national Study). Next, cubital vein blood was collected for laboratory tests, and the levels of bioelements (Mg, Ca, Cu, Fe, Zn) in blood serum were determined. The analysis of the research material did not demonstrate substantial differences in the mean serum levels of Ca, Mg, Zn, Cu, Fe between smokers and non-smokers, alcohol consumers and non-consumers, drug users and non-users. There were no statistically significant correlations between the levels of bioelements and the frequency of drinking beer and vodka (p>0.05). A statistically significant correlation was observed between Cu levels and drinking wine (p≤0.05). Subjects showing aggressive behaviours (getting into scuffles) had lower Mg and Zn levels than other secondary school students. There were weak but statistically significant correlations between Cu levels and the frequency of wine consumption, and between serum Zn levels and smoking marijuana among the subjects.
