Cohort Study of Cannabis Use History and Perinatal Cigarette Use Among Overweight and Obese Women.

OBJECTIVES: In non-pregnant populations, cannabis use and cannabis use disorder (CUD) have been linked to tobacco use and less successful quit attempts. We compared perinatal cigarette use in women across 3 groups: never used cannabis (No CU group); used cannabis but did not meet CUD criteria (CU group); history of CUD (CUD group). METHODS: Interviews with 257 pregnant women with overweight/obesity (M age = 28 years; 52% white) were conducted for a study of eating behavior in Western Pennsylvania from 2012-2016. Tobacco use was assessed early in pregnancy (< 20 weeks gestation), late in pregnancy (34-38 weeks gestation) and 6 months postpartum. CUD was measured with the Structured Clinical Interview for DSM-IV (SCID). Data relevant to the proposed analyses were available for 252 women. Generalized mixed effect models were used to predict perinatal cigarette use based on cannabis use group, time and their interaction, adjusting for age, race, education, income, parity, and mood/anxiety disorder. RESULTS: Forty-eight percent of participants reported prior cannabis use and 15% were diagnosed with lifetime CUD. History of cannabis use predicted cigarette smoking in early pregnancy (OR 11.12, CI 3.27-37.85), late pregnancy (OR 6.55, CI 1.70-25.27), and 6 months postpartum (OR 7.57, CI 2.72-21.07), regardless of CUD. CONCLUSIONS: A history of CUD did not appear to confer additional risk for perinatal cigarette use. Given increasing rates of cannabis use among pregnant women, these results highlight the importance of addressing history of cannabis use in conjunction with tobacco use to improve smoking cessation efforts.

Childhood traumatic events and loss of control eating in pregnancy: Findings from a community sample of women with overweight and obesity.

Although eating disorder symptoms generally decrease in pregnancy, loss of control eating (LOC), defined by the consumption of food accompanied by a sense of being unable to control what or how much is eaten, often persists and may develop in pregnancy. Given that LOC is associated with higher weight status and psychological distress, it is important to understand factors associated with perinatal LOC. Although childhood traumatic events have been linked to LOC in non-pregnant women, the impact of such events on LOC in pregnancy is unknown. Accordingly, the present study aimed to examine the association between a history of childhood traumatic events and LOC prior to and during pregnancy among a community sample of pregnant women with overweight or obesity. Pregnant women (N = 244) were enrolled in a longitudinal study. Women completed interviews between 12 and 20 weeks gestation to document a history of childhood traumatic events and the presence of LOC in the three months prior to and during their current pregnancy. Women were assessed for LOC monthly for the remainder of pregnancy. Results from a multinomial regression model showed that women with a history of childhood traumatic events had higher odds of engaging in LOC both prior to and during pregnancy (OR = 2.52, 95% CI [1.13, 5.64], p = 0.02) but not during pregnancy only (OR = 1.58, 95% CI [0.87, 2.89], p = 0.39). These findings indicate that women with a history of childhood traumatic events may be especially prone to LOC in the months prior to conception that continues throughout pregnancy.

Factors associated with early gestational weight gain among women with pre-pregnancy overweight or obesity.

The present study aimed to document the prevalence of and identify factors associated with excessive gestational weight gain (GWG) in early pregnancy among women with pre-pregnancy overweight or obesity. Women with pre-pregnancy overweight or obesity (n = 247) were recruited between 12 and 20 weeks of gestation and completed questionnaires and were weighed to estimate early GWG. Nearly one-third of women met (17%, n = 42) or exceeded (13%, n = 33) guidelines for total GWG in early pregnancy. Univariate analyses showed race, income, and pre-pregnancy weight status to be significantly related to GWG category in early pregnancy (p < .009). Only race and pre-pregnancy weight status remained significant in a multivariate model, with Black women and women with pre-pregnancy obesity having higher odds of having met or exceeded guidelines for total GWG in early pregnancy compared with White women and women with pre-pregnancy overweight (p < .04). These findings highlight the need for early intervention to reduce weight-related complications among pregnant women.Impact statementWhat is already known on this subject? Women with pre-pregnancy overweight or obesity who gain excessive gestational weight early in pregnancy are at unique risk for pregnancy complications and adverse birth outcomes.What do the results of this study add? The present study adds to a growing body of literature documenting that a notable amount of women are gaining excessive gestational weight early in pregnancy. The present study further documents that Black women and women with pre-pregnancy obesity are at particular risk of gaining excessive gestational weight early in pregnancy.What are the implications of these findings for clinical practice and/or further research? Additional work examining modifiable risk factors, particularly among Black women and women with pre-pregnancy obesity, that contribute to excessive gestational weight gain (GWG) in the first half of pregnancy is warranted and will be necessary to inform interventions aimed at promoting weight loss during the preconception and interconception periods or encouraging appropriate GWG across the entire course of pregnancy.

Healthcare provider advice on gestational weight gain: uncovering a need for more effective weight counselling.

Limited research has examined the factors related to knowledge of gestational weight gain (GWG) recommendations and the receipt of advice from healthcare providers regarding GWG recommendations among women with pre-pregnancy overweight/obesity. Women with pre-pregnancy overweight/obesity (N = 191) reported the amount of gestational weight they believed they should gain and that healthcare providers advised them to gain. Only 24% (n = 46) of women had a correct knowledge of GWG recommendations. Women were less likely to have a correct knowledge of GWG recommendations if they had pre-pregnancy obesity, were of a minority race, or were socioeconomically disadvantaged. Meanwhile, only 17% (n = 32) of women reported being correctly advised about GWG recommendations by healthcare providers. There were no differences between women who did and did not report being correctly advised about GWG recommendations from healthcare providers. These findings indicate that women with pre-pregnancy overweight/obesity lack knowledge of GWG recommendations and report being incorrectly advised about GWG recommendations from healthcare providers. Impact statement What is already known on this subject? Extant literature indicates that women's knowledge of gestational weight gain (GWG) recommendations and women's receipt of information from their healthcare providers regarding GWG recommendations are predictive of meeting the Institute of Medicine guidelines for GWG. What do the results of this study add? Findings from the present study indicate that the majority of women with pre-pregnancy overweight/obesity lack knowledge of GWG recommendations and report that education on GWG recommendations from healthcare providers is an aspect of their prenatal care that is largely insufficient. Although there were no differences between women who did and did not report being correctly advised about GWG recommendations by healthcare providers, women were less likely to have a correct knowledge of GWG recommendations if they had pre-pregnancy obesity, were of a minority race, or were socioeconomically disadvantaged. What are the implications of these findings for clinical practise and/or further research? These findings highlight a need for more effective tailoring of prenatal care to ensure that women receive accurate advice from healthcare providers regarding GWG recommendations.
