Lifestyle of students from different universities in Wroclaw, Poland.

BACKGROUND: Changes in the economic and political system that took place in Poland in recent decades had a significant impact on lifestyles of different social groups, especially in youngsters as vulnerable and open to all novelty and changes. OBJECTIVE: The aim of this study was to evaluate the healthy or non-healthy behaviours including physical activity, diet, time devoted for sleeping, leisure, stress and the use of drugs by students of four universities in Wroclaw. MATERIAL AND METHODS: The study involved 604 students (305 women and 299 men) from four universities in Wroclaw: University of Wroclaw - 25.0%, Wroclaw University of Technology - 24.5%, University School of Physical Education (AWF) - 25.2% and Wroclaw Medical University - 25.3%. A questionnaire developed for this study was used. The questions were both open and closed, one or multiple answers could be matched. The questions related to: physical activity, nutrition, time devoted for sleeping, leisure, stress and stimulants. RESULTS: On the basis of the results it was found that students mostly reported an average level of physical activity. The highest level of physical activity was presented by students of the University School of Physical Education and the lowest by students of the University of Wroclaw. Just one in ten students consumed meals on a regular basis, including one in five studying in the AWF. Almost half of the respondents (48.7%) spent 5-7 hours sleeping. Every tenth student slept less than five hours. Most respondents preferred passive forms of recreation, only one in three practiced sports in their spare time (usually students of the AWF). Every fourth student declared smoking, and more than 90% consumed alcohol. CONCLUSIONS: Lifestyle of majority of the students surveyed did not follow the recommendations of preventive care. The need for more efficient education of students is obvious, which will lead to the future positive changes in their lifestyle, reducing the risk of lifestyle diseases.

Effect of attending childbirth education classes on psychological distress in pregnant women measured by means of the General Health Questionnaire.

BACKGROUND: Pregnancy brings about many changes in a woman's life in somatic, psychological and social spheres. Therefore, many women decide to participate in childbirth education classes. The aim of study was to determine the differences in emotional distress between women who participated in childbirth education classes and these who did not. MATERIAL AND METHODS: Seventy first-time mothers after labor were examined. Based on a survey carried out, the women were divided into two equal groups. Group I consisted of women who had participated in childbirth education classes and Group II of women who had not. The data was gathered by means of the General Health Questionnaire (GHQ-12) adapted to Polish conditions. RESULTS: There were no differences either in age or in BMI rates among the examined women. The level of education and knowledge about labor was significantly higher among the participants of childbirth classes. The results of the GHQ-12 revealed that women from Group I had a better mental status than women from Group II. Significant differences were observed in terms of sleep deprivation, overcoming difficulties and in the ability to enjoy daily activities. CONCLUSIONS: Participation in childbirth classes has a significant influence on psychological well-being in pregnant women as measured by the GHQ-12.

Melanocortin-4 receptor gene polymorphism and the level of physical activity in men (HALS Study).

Melanocortin plays an important role in the energy balance in humans. Actions of melanocortin are exerted through activation of five receptors among which the melanocortin-4 receptor (MC4R) is especially abundant within the central nervous system (CNS). It has been proved that genetic variations of the MC4R gene are associated with the energy intake. Recent data has suggested that MC4R gene polymorphism might influence physical activity/energy expenditure as well. Our aim was to search for associations between MC4R polymorphisms and the level of physical activity. We genotyped MC4R in a population-based cohort of 311 men. The level of physical activity was determined with use of the International Physical Activity Questionnaire. We have found that physical effort expressed as log METs-min/week (corrected for age, BMI and educational status) was 6.61 in men declaring low, 7.56-moderate and 8.96-high level of physical activity. We have not found any associations between the C-2745T MC4R polymorphism and the level of physical activity (P = 0.53). There were no interactions between the level of physical activity and the C-2745T polymorphisms either (P = 0.47). We conclude that the C-2745T genetic polymorphism of the MC4R gene does not influence the level of physical activity in healthy, adult men.
