Introduction. Environmental conditions have been changing over the years and the body’s capacity to adapt affects human development, its growth and typogenesis. Aim. To confirm the secular trend in the population of children and adolescents aged 4 to 18 from Rzeszów in the last 35 years in terms of growing and differentiation body proportions. Materials and methods. In 2013/2014, a total of 1,563 children from Rzeszów were examined. The length of the trunk, the upper limb, the lower limb, the width of the shoulders and the width of the hips were measured and the following indices were calculated: trunk length, upper limb length, lower limb length, inter-limb, hip-shoulder and shoulder width. The data was subjected to statistical analysis and compared to the data collected in 1978/79, 1993/1994 and 2003/2004. Results. During the 35-year period, the following symptoms were observed: elongation of upper and lower limbs in both sexes, increase in shoulder width in boys from 15-18 years of age, and in girls generally in the entire examined age, tendency to decrease in hip width in both sexes in most age classes. Conclusions. The secular trend in the population of children and adolescents aged 4 to 18 from Rzeszów in the last 35 years regarding growth process and differentiating body proportions was confirmed.

Introduction. Changes occurring over the years in environmental conditions and in organism’s adaptability contribute to changes in the human morphological and functional phenotype. Purpose of the study. Assessment of progress in body weight, body height, chest circumference, as well as Quetelet II (BMI), Rohrer, and Marty indexes in children and adolescents from Rzeszów, aged 4-18, and changes in the period of the recent 35 years. Material and methods. The total of 1,563 children from Rzeszów were examined in 2013/2014. Measurements were carried out to identify body weight, body height, chest circumference; based on that Quetelet II, Rohrer, and Marty indexes were calculated. Results. The findings, presented in tables and figures, have been interpreted. Conclusions. Somatic growth in the examined population is consistent with generally recognized regularities. The secular trend continues in the period of 35 years. It is impossible to make an explicit claim regarding stabilization of growth during the last 10 years.
Trend sekularny występowania cukrzycy typu 1 w województwie podkarpackim w latach 2009- 2019
(Uniwersytet Rzeszowski, 2023-01-27) Brzuszek, Marta
Cukrzyca typu 1 jest jedną z najczęściej rozpoznawanych chorób wieku dziecięcego. Na świecie, w Europie, a także w Polsce, liczba zachorowań gwałtownie wzrasta. Średni wskaźnik zapadalności na cukrzycę typu 1 w populacji dzieci i młodzieży do 18. roku życia, w badanych latach 2009- 2019 wynosi 21,2 dzieci/ 100 tys. osób/ rok. Powiaty o najwyższym wskaźniku zapadalności to: strzyżowski, przeworski i łańcucki ( 30/ 100 tys./ rok). Zaobserwowano wzrastającą tendencję wskaźnika zapadalności we wszystkich grupach wiekowych, w szczególności w grupie dzieci w wieku 5-9 i 10- 14 lat. Zapadalność była większa i istotnie zróżnicowana w populacji chłopców w poszczególnych powiatach oraz w grupie dzieci zamieszkujących w mieście. Potwierdzono także istotną statystycznie zależność pomiędzy liczbą zachorowań, a sezonem zachorowania. Najwięcej dzieci zachorowało w październiku i listopadzie, a najmniej w maju i w czerwcu.
