[Assessment of association of birth weight and existence of hypertension in children and adolescents normostenic, obese or with metabolic syndrome]. / Masa urodzeniowa ciala a wystepowanie nadcisnienia tetniczego w grupie dzieci i mlodziezy normostenicznej, z otyloscia lub z cechami zespolu metabolicznego.

UNLABELLED: It has been proved that Low Birth Weight (LBW) is a predisposing factor of elevated blood pressure in children. The aim of our study was to analyze birth weight of patients with diagnosed hypertension (HT). There has been 114 children, 6 to 17 years old, included into our study. We decided to divide them into 3 following groups: Group I--normal body mass and HT (51 children); Group II--metabolic syndrome (MS) with HT (32 children); Group III--overweight and obese children with HT (31 children). At 85% of all patients HT was diagnosed after performing ABPM. Statistically significant difference of birth weight was observed between patients with normal body mass (I) and those with overweight or obesity (III) (p<0,01). The most number of children with LBW (<2500 g) was observed in Group I (15.7%) and Group II (12.5%). It was observed that obese children with HT had had normal or high birth weigh (96.8%). CONCLUSION: 1. The frequency of low birth weight is similar in normostenic children with hipertension and children with metabolic syndrome. 2. The birth weight higher than 4000 g is more frequent in obesy hipertensive children and children with metabolic syndrome than in normo-stenic patients with hipertension.

[Evaluation of infants and younger children passive smoking at home and prevalence of their lower respiratory tract infectious]. / Ocena narazenia niemowlat i dzieci mlodszych na bierne palenie tytoniu w srodowisku domowym w odniesieniu do czestosci wystepowania u nich zapalen dolnych dróg oddechowych.

The nicotine's metabolites were determined in urine of 92 children--59 children of smoking parents (SP) and 33 of non-smoking parents (NSP). The level of metabolites of nicotine and the ratio of the nicotine's metabolites to creatinine concentration were analyzed in infants (older than 5 months) and children 2-4 years old. Moreover the frequency of bronchitis and pneumonia in children was estimated on the basis of the interview with their parents. The nicotine's metabolites concentration was significantly higher in urine of children of SP than in urine of NSP children, as well in the group of infants as in children aged 2 to 4 years. Respiratory tract infections were frequent in 69.4% of SP children and in 21.1% of NSP children. In addition, the mean and the highest level of metabolites of nicotine in urine of SP children were multiple higher in comparison to the levels found in the group of NSP children suffering from the respiratory tract infections with equal frequency.
