Abstract

OBJECTIVE:

To analyze the risk factors of low birth weight, the authors conducted a matched case-control study.

METHODS:

155 women which infants were singleton term SGA cases and 155 with singleton term non-SGA controls were interviewed. Cases and controls were matched by infant sex and maternal age. Analyses were performed by conditional logistic regression.

RESULTS:

Low prepregnancy weight (< or = 52kg), low weight gain (< or = 16kg), passive smoking and drinking tea during pregnancy, dying hair, marcel or curium oil three month before pregnancy and during pregnancy, low husband height (< 173cm), and maternal BMI (> or = 19) were associated with risk of term SGA. The odds ratio of those risk factors were 2.08, 2.83, 3.07, 2.94, 3.42, 2.72, 5.67, 2.92 and 0.41 respectively.

CONCLUSION:

It was also found significant positive interactions between low maternal weight and low weight gain, and dying hair, marcel or curium oil three month before pregnancy and during pregnancy, and low husband's height, and passive smoking during pregnancy.
