[Selected eating habits and caries occurrence in adolescents]. / Wybrane zachowania zywieniowe a wystepowanie próchnicy U Mlodziezy.

INTRODUCTION: Normal nutrition is an important element of caries prophylaxis. The aim of the study was to evaluate the influence of chosen bad eating habits on caries occurrence in adolescents. MATERIAL AND METHODS: The examination was carried out in the group of 367 (68.5% girls and 31.5% boys) pupils of the 3rd year of high schools in Bialystok in 2011. Own questionnaire was used for the evaluation of eating habits. Caries intensity (PUW) was assessed by dental examination. To verify statistic hypotheses, the level of significance was estimated at p < 0.05. All calculation was performed with the use of the Statistic programme Statistica 7.0 (StatSoft). RESULTS: It was stated that 5 meals a day were consumed by 29.4% of examined pupils, 4 meals were eaten by 33.2%, 3 meals--by 31.3%, 2 meals--by 5.4%, and one meal was consumed by 0.5% of pupils. There were 55.3% of pupils who had irregular meals while 24.3% did not eat breakfast and 62.9%--did not have elevenses. Eating between meals was stated in 96.7% of pupils. Sweets consumption was revealed as follows: 16.8% several times a day, 19%--once a day, 40.5%--several times a week, 18.5%--several times a month, 5.2%--rarely or never. "Fast food" was not consumed by 34% of examined pupils while 54.6% consumed such meals several times a month, 10.9%--several times a week, and 0.5%--once a day. Higher level of caries intensity was observed in girls (mean coefficient PUW = 11.3) than in boys (mean coefficient PUW = 10.8). Mean coefficient PUW = 11.5 concerned pupils with consumption of fast food several times a month while PUW = 11.0 in those who consumed it several times a week, and PUW = 10.7 in pupils who eat rarely or never such food. As far as eating sweets, PUW was higher than mean (12.4) in pupils who eat sweets several times a day. Persons who eat between meals were characterized by higher coefficient (PUW = 13.0) as compared to those who eat between meals rarely (PUW = 11.3) and those who do not eat between meals (PUW = 8.9). CONCLUSIONS: (1) Bad eating habits (irregular meals, skipping breakfast, eating between meals as well as overeating sweets) in the developmental age can be a significant caries coefficient in adolescents. 2. High mean coefficient PUW in the examined group of 18-year-old pupils, in relation to abnormal eating habits in the significant percentage of those pupils, indicates the necessity of health education as far as caries prophylaxis is concerned.

[Helicobacter pylori genome alleles S1 and S2 and morphological changes gastric mucosa in children and adults in the Bialystok province]. / Allel S1 I S2 genomu helicobacter pylori a zmiany morfologiczne blony sluzowej zoladka u dzieci I doroslych w województwie podlaskim.

UNLABELLED: Bacteria virulent proteins, among other vacA, have a significant role in the occurrence of gastric mucositis. AIM: The aim of the study was the evaluation of occurrence rate of alleles s1 and s2 of Helicobacter pylori vacA genome in children and adults, inhabitants of the Podlasie province. It was also to determine the correlation between infection with a determined s1 or s2 vacA genotype of the bacterium and the degree of severity and activity of antral mucositis. METHODS: 68-H. pylori infected persons (38 children and 30 adults) were examined, vacA genotypes of 70 H. pylori strain were evaluated. RESULTS: The degree of inflammatory changes in antral mucosa was differentiated and depended on vacA alleles of H. pylori strain. Allele s1 more frequently coexisted with moderate and severe antral mucositis in adults than in children (56.3% vs 50,0%, respectively). Allele s1 occurrence correlated with high activity inflammation in 47.5% of cases, medium activity--18.6%, and low activity--5.1%. CONCLUSIONS: Allele s1 was more frequently stated both in children and adults (86.8% and 81.3%, respectively) as compared to allele s2. Allele s1 also more frequently coexisted with low-activity inflammation or with no-activity inflammation of antral mucositis in children than in adults (36.8% vs 18.8%, respectively).
