Table 4 shows the results of multiple linear regression models of the behavioral and dietary restrictions score on health-related quality of life and the perceived stress score after controlling for demographic, socioeconomic, obstetric and medical variables. Among the variables, only the Physical health component (PCS) of Health-related quality of life (SF-12) was significant (β = –.127, p < .001); the pregnant women who adhered to behavioral restrictions were more likely to be those who had poor physical health. However, there was no significant difference in PSS scores (p > .05) between the pregnant women who had adhered to pregnancy restrictions and those who had not.
