Smoking concordance during pregnancy: Are there relationship benefits?

Couples often engage in similar patterns of behavior, including substance use, and similarity may benefit relationship quality. Such relationship benefits may be especially salient for adolescent and young couples, whose relationships are often unstable and prone to breakups. This study examined the effect of mutual smoking during pregnancy on relationship quality in pregnant adolescent and young adult couples. Methods Couples (N = 228; M AgeFemale  = 18.69; M AgeMale  = 21.12) were recruited from obstetrics/gynecology clinics in Connecticut from July 2007 to February 2011. Couples completed measures of recent smoking and relationship quality (i.e. satisfaction, affectional expression, cohesion, and consensus) during pregnancy and at six months postpartum. Data were analyzed using multilevel models to account for interdependence within dyads. Results Discrepant smoking patterns were associated with a reduction in satisfaction and cohesion over time (B = −1.14, p = 0.03, and, B = −2.74, p = 0.03, respectively), and a reduction in consensus over time for female participants, B = −1.98, p = 0.07, but not for male participants, p = 0.51. Discrepant smoking was not related to affectional expression, p = 0.11. Conclusions Results suggest relationship benefits concordant smoking patterns during pregnancy. Interventions should consider potential unintended relationship consequences of changing individual health behavior and instead work to develop couple-level health interventions.
