بازداری رفتاری و رویکرد رفتاری در بزرگسالان جوان با وزن بسیار کم هنگام تولد - مطالعه هلسینکی بزرگسالان با وزن تولد بسیار پایین

We compared 164 VLBW young adults, of whom 54 were born small for gestational age (SGA, <−2 SD) and 110 appropriate for gestational age (AGA, −2 to +2 SD), with 172 term controls. Behavioral inhibition and behavioral approach were assessed with the BIS/BAS Scales. The VLBW participants scored lower than the controls on BAS-related fun seeking. Further, the VLBW-SGA women scored higher than the control women on behavioral inhibition and the VLBW-SGA men scored higher than the VLBW-AGA men on BAS-related drive. Results remained similar after adjustment for major confounders (age, body mass index and parental education). Our results indicate that perinatal conditions such as severely preterm birth and small birth weight for gestational age may be related to differences in adulthood personality.
