The effects of prenatal exposure to pollutants from the World Trade Center (WTC) disaster on fetal growth and subsequent health and development of exposed children remain a source of concern. We ...assessed the impact of gestational timing of the disaster and distance from the WTC in the 4 weeks after 11 September on the birth outcomes of 300 nonsmoking women who were pregnant at the time of the event. They were recruited at delivery between December 2001 and June 2002 from three hospitals close to the WTC site. Residential and work addresses of all participants for each of the 4 weeks after 11 September 2001 were geocoded for classification by place and timing of exposure. Average daily hours spent at each location were based on the women's reports for each week. Biomedical pregnancy and delivery data extracted from the medical records of each mother and newborn included medical complications, type of delivery, length of gestation, birth weight, birth length, and head circumference. Term infants born to women who were pregnant on 11 September 2001 and who were living within a 2-mile radius of the WTC during the month after the event showed significant decrements in term birth weight (-149 g) and birth length (-0.82 cm), compared with infants born to the other pregnant women studied, after controlling for sociodemographic and biomedical risk factors. The decrements remained significant with adjustment for gestational duration (-122 g and -0.74 cm, respectively). Women in the first trimester of pregnancy at the time of the WTC event delivered infants with significantly shorter gestation (-3.6 days) and a smaller head circumference (-0.48 cm), compared with women at later stages of pregnancy, regardless of the distance of their residence or work sites from the WTC. The observed adverse effects suggest an impact of pollutants and/or stress related to the WTC disaster and have implications for the health and development of exposed children.
Cilj rada. Ispitati odnos između porodne težine i duljine te težine, visine i BMI odrasle žene. Ispitanice i metode. U 735 zdravih žena određena je prosječna životna dob (godine), prosječna porodna ...težina (g) i duljina (cm), zatim prosječna težina (kg), visina (cm) i BMI kg/m2. BMI do 19,9 je nizak, od 20,0 do 24,9 je normalan (idealan), od 25,0 do 29,9 je visok (velika težina), a od 30,0 i veći je vrlo visok (pretilost). Statistička obrada učinjena je pomoću aritmetičke sredine (x), standardne devijacije (SD), 2-testa uporabom n X m tablica kontingencije s nul-hipotezom i analizom vari¬janci. Razlika je značajna ako je p manji od 0,05. Rezultati. Prosječna životna dob odraslih ispitanica iznosi 27,86±5,4 godine, porodna težina 3490,2±544,2 g, a duljina 51,4±3,76 cm. Prosječna težina odrasle žene je 64,03±9,32 kg, visina 169,9±11,9 cm i BMI 22,77±6,74 kg/m2. Povećanjem porodne težine i porodne duljine povećava se tjelesna težina, visina i BMI kg/m2 odrasle žene (p<0,009). Povećanjem porodne težine smanjuje se broj odraslih žena s niskim (do 19,9 kg/m2) BMI, a povećava s visokim (25,0 kg/m2 i veći) BMI (p<0,001). Povećanjem porodnih duljina ne povećava se učestalost odraslih žena s niskim, umjerenim, visokim i vrlo visokim BMI (p>0,05). Među ispitanicama je 19,4% s niskim, 64,0% s umjerenim, 15% s visokim i 1,4% s vrlo visokim BMI. Zaključak. Postoji dobra pozitivna povezanost između porodne težine i duljine te prosječne tjelesne težine, visine i BMI odrasle žene. Porodna duljina nema utjecaja na raspodjelu odraslih¬ žena prema skupinama BMI. Visoka je učestalost pretilih i ekstremno pretilih žena mlađe životne dobi.
