Introduction: Research across the past 4 decades has supported a cross-sectional association between adult cigarette smoking and lower fruit and vegetable consumption (FVC), and emerging research suggests higher FVC may predict cessation. Among youth, findings are limited to a few cross-sectional studies with somewhat mixed results. Here we evaluated the FVC-smoking association among youth both cross-sectionally and longitudinally.

Methods: We analyzed data from a subsample of the National Longitudinal Survey of Youth 1979: Child and Young Adult. The subsample included adolescents aged 14-18 years at baseline in the year 2004. Multivariable cross-sectional analyses assessed whether baseline FVC was associated with smoking frequency among ever-smokers (n = 578). Longitudinally, the study assessed whether baseline FVC predicted smoking progression among baseline never-smokers who tried a cigarette by 4-year follow-up (n = 388). Multivariable regression models adjusted for age, gender, race/ethnicity, parental education, and health behavior orientation.

Background: Studies have consistently reported associations among depression, cigarette smoking, and fruit and vegetable intake (FVI). This study evaluated FVI as a moderator of the association between depressive symptoms and smoking.

Methods: We analyzed data from the National Longitudinal Survey of Youth 1979: Child and Young Adult. The study sample was adults aged 19–33 years at baseline in the year 2004 from the Young Adult Survey portion. Moderation analyses were performed using the Johnson-Neyman technique to assess whether baseline FVI moderated the association between depressive symptoms and smoking status cross-sectionally and as a predictor of smoking cessation longitudinally at 4-year follow-up.

Results: Cross-sectionally, at lower levels of FVI (< 4.9 times/day) there was a significant association between smoking and depressive symptoms (p < .05), but not at higher levels of FVI (≥ 4.9 times/day; p > .05). Longitudinally, there was an inverse association between depressive symptoms and quitting smoking at FVI < 1.2 times/day (p < .05), but there was not a significant association at FVI ≥ 1.2 times/day (p ≥ .05).

Conclusions: FVI moderated the association between depressive symptoms and cigarette smoking cross-sectionally and longitudinally. The cross-sectional findings might be partially explained by the longitudinal findings paired with prior research; there might be fewer smokers with high FVI because depressive symptoms are removed as an impediment to cessation. Further experimental research is warranted to test the efficacy of increased FVI as an adjunct to smoking cessation with a possible mechanism of action being reduced depressive symptoms during quit attempts.
