The authors conducted a study of women's ability to recall diet during a past pregnancy. For a prospective study, women completed self-administered food frequency questionnaires (FFQs) before and during pregnancy (1989-1992). These women, mostly White and well-educated, were contacted 3-7 years later (1996-1997) for a retrospective dietary assessment performed by either telephone interview (n = 154) or self-administered FFQ (n = 115). Energy-adjusted Pearson correlations ranged from 0.10 to 0.49 for the telephone interview group and from 0.02 to 0.67 for the self-administered questionnaire group. When participants' intakes were ranked, quintile agreement (within one quintile) between original diet and recalled diet ranged from 60% to 69% in the telephone interview group and from 69% to 79% in the self-administered questionnaire group. Correlations and percentages of agreement were higher among women who used the same questionnaire for both dietary assessments than among those who used different questionnaires. These results suggest that diet during pregnancy is recalled with similar accuracy as or perhaps slightly lower accuracy than adult diet generally. This may reflect, in part, the influence of current (nonpregnancy) diet on recall of past (pregnancy) diet. While the results of this study may not be generalizable to those obtained from other populations, to the authors' knowledge it is the first study of recall of diet during pregnancy.

To examine the association between mental health factors with smoking cessation during pregnancy and postpartum relapse. We used data from 1,416 women who participated in the Minnesota Pregnancy Risk Assessment Monitoring System survey in 2004-2006 and reported smoking immediately prior to pregnancy. Maternal mood during pregnancy, stressful life events and postpartum depression were the mental health variables. We used multivariate logistic regression to examine the association between these variables and two outcomes, smoking cessation during pregnancy and postpartum relapse. Stressful life events was associated with smoking cessation in multivariate regression models, however maternal mood was not. Smoking cessation was also associated with pre-conception smoking intensity, maternal education, and income. Maternal mood, stressful life events and postpartum depression were not associated with relapse in multivariate regression models. Breastfeeding at the time of the survey was the strongest correlate of relapse, with women who breast fed 60% less likely to resume smoking during the postpartum. Post-hoc analysis suggests that mental health variables may interact with other mitigating factors to influence smoking behavior during pregnancy. Mental health variables may be important to successful prenatal smoking cessation. Further research with larger sample sizes is needed to explore the possibility of interactive relationships between mental health variables and other co-factors on prenatal smoking cessation and postpartum relapse.

The main objective of this work is to examine low prenatal mood, alcohol and tobacco use and rates of preterm (PTB) and low birth weight (LBW) births among women in Minnesota between 2002 and 2006. We examined the Minnesota version of the national, cross-sectional survey of postpartum women, the Pregnancy Risk Assessment Monitoring System (MN PRAMS). Of the 11,891 women sampled in 2002-2006, 7,457 had complete data for analysis; the weighted response rates averaged 76%. The major variables of interest were: LBW, PTB, maternal mood during pregnancy, prenatal alcohol use, prenatal tobacco use and interaction terms created from the mood and substance use variables. Women with low mood who used tobacco during pregnancy were twice as likely to have a LBW infant as women who did not smoke and reported high mood (AOR = 2.12, 95% CI: 1.35, 3.33, P = 0.001). Among women who abstained from alcohol during pregnancy, those with low mood were at an increased risk for PTB (AOR = 1.95, 95% CI: 1.54-2.45, P < 0.0001) compared to women with high mood. Low maternal mood was associated with increased risks for PTB, and LBW births among MN PRAMS respondents. Substance use and low prenatal mood co-occur and the combined effect on PTB and LBW birth outcomes warrants further investigation.

This study linked birth certificates with Minnesota Medicaid deliveries in order to identify Medicaid births. This article describes the link between methodology and results. Medicaid claims from 1997 were used to identify women with a delivery code. Identifiers for these women were linked to birth certificate files, with a match rate of 93.2 percent. Women's match status did not differ by maternal age. Women in some border counties matched at much lower rates than the rest of the population. The methodology was effective in linking Medicaid and birth certificate data and will be implemented as a data linkage protocol for Minnesota.
