The aim of this study is to evaluate the prevalence of overweight and obesity in a sample of children who were exclusively or predominantly breastfed for at least 6 months compared to Czech references that were constructed based on a representative sample of children, regardless of their mode of feeding. Between 2008 and 2011, a longitudinal study on the growth of breastfed infants was carried out in the Czech Republic. Forty-three GP pediatricians addressed parents at 18-month preventive examinations and collected data on the families’ socio-economic conditions and the infants’ feeding conditions. The children were measured (length, weight, and head circumference), and anthropometric measurements from 10 previous preventive examinations were obtained from the health records. Out of the collected 1775 questionnaires, 960 children were selected according to the criteria of the WHO Multicentre Growth Reference Study. For the purpose of this study, 799 children who were exclusively or predominantly breastfed for at least 6 months were selected. We found that the proportions of children who were classified as overweight (>90th percentile) or obese (>97th percentile) at 6, 12, and 18-month examinations were far below the proportions of the Czech references. An update of the Czech references and growth charts is highly recommended by GP pediatricians for the valid assessment of growth and nutritional status, including a screening of overweight and obesity in primary preventive health care.

This study seeks to assess smoking habits, attitudes and intention to quit in students of the Third Faculty of Medicine of Charles University in Prague, Czech Republic. A cross-sectional survey designed to obtain information on smoking history, current smoking status, cessation attempts, and attitudes towards smoking among health professionals was conducted in 452 students of the first and last years of a 6-year Master's Study Programme (General Medicine) and a 3-year Bachelor's Study Programme (Public Health). An anonymous questionnaire was administered during the classes in the course of academic years 2011-12 and 2012-13. 5.7% of the Master's Study Programme students (3.3% women and 9.0% men ) and 4.8% of the Bachelor's Study Programme students reported that they are regular smokers. The share of regular smokers was almost twice as big in students of the English Curriculum of the Master's Programme (10.7%) in comparison with the students of the Czech Curriculum (4.5%), and more than twice as big in students of the last years of both study programmes (3.9% in students of the 1st year and 10.8% in students of the 6th year of the Master's Programme; 3.2% in students of the 1st year and 7.0% in students of the 3rd year of the Bachelor's Study Programme). At the time of the research, 18.9% of students of the Master's Programme and 17.1% of students of the Bachelor's Programme were occasional smokers. 5.9% of students of the Master's Programme and 19.0% of students of the Bachelor's Programme reported that they quit smoking during their studies at the medical faculty; on the contrary, 9.8% of students of the Master's Programme and 14.3% of students of the Bachelor's Programme started smoking during that time. Smoking in health professionals undermines their significant role in health promotion and prevention of chronic diseases in their patients. Therefore, education at the medical faculty should focus on motivation of future health professionals towards non-smoking except providing knowledge on current research and guidance on early identification and further intervention in smokers.
