Association between generational status and smoking behaviors before and during pregnancy among Hispanic women

Abstract

Background: Evidence is limited on the risk of maternal smoking before and during pregnancy across generations of Hispanic immigrants.

Purpose: The aim of this study was to determine whether immigration generational status predicts maternal smoking behaviors before and during pregnancy among Hispanic women.

Methods: Data on pregnancies in National Longitudinal Survey of Youth 1979 were used. Current study sample consists of Hispanic women (15-24 years) reporting pregnancy between 1979 and 2014 (n = 616). Data on birthplaces of the respondent and their parents were used to determine generation status. Maternal smoking behaviors before and during pregnancy were self-reported. Data were analyzed using weighted covariate-adjusted logistic regression models.

Results: There were 24% first-generation, 20% second-generation, and 56% third or higher generation Hispanic women in the sample. Majority of participants were married (72%), with a high school degree or more (69%), and of Mexican origin (56%). After controlling for covariates, first generation Hispanic women had lower likelihood of smoking prior to (OR = 0.40, p = 0.009) and during pregnancy (OR = 0.35, p = 0.007) compared to third or higher generation women. The second-generation women had lower likelihood of smoking during pregnancy (OR = 0.46, p = 0.038) compared to third or higher generation women.

Conclusions: First generation Hispanic women are at lower risk of smoking both prior to and during pregnancy. Identification of cultural factors discouraging smoking during pregnancy among first/second generation Hispanic women and incorporating in smoking prevention interventions targeting Hispanic women could benefits the later generations of Hispanic immigrants.
