Behaviors during pregnancy including eating, exercise, cigarette smoking, and other substance use affect the health of a pregnant woman and her fetus. However, little is known about what influences pregnant women to engage in these health behaviors. Based upon relevant theory, we hypothesized that because health-promoting behaviors require continuous efforts that may depend upon a reliable, stable set of resources, intrapersonal traits, namely self-esteem and optimism, would be associated with the practice of health-promoting behaviors during pregnancy. In addition, we hypothesized that variables reactive to the more immediate context, pregnancy-specific stress and perceived control over pregnancy, would be associated with the practice of health-impairing behaviors. We distinguished health-promoting and health-impairing behaviors in a diverse sample of 165 pregnant women and investigated whether such behaviors are associated with distinct psychosocial factors. Results supported study hypotheses and provide evidence that even after controlling for maternal age, income, body mass index, and gestation, a stable, self-relevant disposition, self-esteem, is associated with the practice of health-promoting behaviors in pregnancy whereas pregnancy-specific stress, a situationally-evoked factor, is associated with the practice of health-impairing prenatal behaviors. Perceived control over pregnancy, which may reflect stable disposition and situational perceptions, was associated with health-promoting and health-impairing behaviors.

IMPORTANCE The US Food and Drug Administration recommends that indoor tanners (ITs) be screened regularly for skin cancer (SC). OBJECTIVE To investigate the association between indoor tanning and SC screening. DESIGN, SETTING, AND PARTICIPANTS The 2015 National Health Interview Survey was a multistage, clustered, cross-sectional design with 30 352 US adults participating. The response rate for the sample adult data used in this study was 55.20% after excluding 1099 individuals who reported a history of SC and 2221 individuals with unknown SC screening or indoor tanning history. To examine the independent correlates of screening, we conducted multiple logistic regressions separately for ITs and nontanners (NTs), simultaneously including all preselected variables of interest as potential predictors. Formal interaction analyses were also performed to determine if the covariate effects differed significantly between ITs and NTs. EXPOSURES Indoor tanning as well as sociodemographic, health care, and SC risk and sun protection factors. MAIN OUTCOMES AND MEASURES The primary outcome was self-reported full-body SC screening by a physician. Univariable and multivariable analyses were conducted to determine the secondary outcome, correlates of SC screening among ITs and NTs. RESULTS A total of 15 777 participants (51.98%) were female, and 23 823 (78.49%) were white; 4987 (16.43%) of the sample had indoor tanned, and 1077 (21.59%) of these had tanned last year. A total of 1505 ITs (30.18%) and 4951 NTs (19.52%) had been screened for SC. Correlates of screening for ITs and NTs were older age (ITs: odds ratio [
