In this Chinese population, CU usually affected youth, and CSU was the most common subtype. Autoreactivity and alcohol consumption were the top two triggers for CU, whereas latent infectious and chronic inflammatory diseases were not as common as in previous reports.

IntroductionKorean women are reluctant to pursue in-person smoking cessation treatment due to stigma attached to women smokers and prefer treatment such as telephone and online smoking cessation programs that they can access secretively at home. However, there is some evidence that face-to-face interaction is the most helpful intervention component for them to quit smoking.MethodsThis study is a pilot clinical trial that examined the acceptability and feasibility of a videoconferencing smoking cessation intervention for Korean American women and compared its preliminary efficacy with a telephone-based intervention. Women of Korean ethnicity were recruited nationwide in the United States and randomly assigned at a ratio of 1:1 to either a video arm or a telephone arm. Both arms received eight 30-minute weekly individualized counseling sessions of a deep cultural smoking cessation intervention and nicotine patches for 8 weeks. Participants were followed over 3 months from the quit day.ResultsThe videoconferencing intervention was acceptable and feasible for Korean women aged <50 years, whereas it was not for older women. Self-reported abstinence was high at 67% and 48% for the video and telephone arm at 1 month post-quit, respectively. The rates declined to 33% for the video arm and 28% for the telephone arm at 3 months post-quit when salivary cotinine test was performed.ConclusionFindings support that both videoconferencing and telephone counseling can be effective, and personal preference is likely an important factor in treatment matching. The deep cultural smoking cessation intervention may account for the outcomes of telephone counseling being better than prior studies in the literature for Korean women.

Background Korean men and women have the highest current smoking rates across all Asian ethnic subgroups in the United States. Methods This is a 2-arm randomized controlled study of a culturally adapted smoking cessation intervention. The experimental condition received eight weekly 40-minute individualized counseling sessions that incorporated Korean-specific cultural elements, whereas the control condition received eight weekly 10-minute individualized counseling sessions that were not culturally adapted. All participants also received nicotine patches for 8 weeks. Results One-hundred nine Korean immigrants (91 men and 18 women) participated in the study. The rate of biochemically verified 12-month prolonged abstinence was significantly higher for the experimental condition than the control condition (38.2% vs. 11.1%, χ2 = 10.7, p < 0.01). Perceived family norm significantly mediated the effect of cessation intervention on abstinence. Discussion Smoking cessation intervention for Korean Americans should be culturally adapted and involve family members to produce a long-term treatment effect.

Smoking during pregnancy is a persistent public health problem that has been linked to later adverse outcomes. The neonatal period-the first month of life-carries substantial developmental change in regulatory skills and is the period when tobacco metabolites are cleared physiologically. Studies to date mostly have used cross-sectional designs that limit characterizing potential impacts of prenatal tobacco exposure on the development of key self-regulatory processes and cannot disentangle short-term withdrawal effects from residual exposure-related impacts. In this study, pregnant participants (N ϭ 304) were recruited prospectively during pregnancy, and smoking was measured at multiple time points, with both self-report and biochemical measures. Neonatal attention, irritable reactivity, and stress dysregulation were examined longitudinally at three time points during the first month of life, and physical growth indices were measured at birth. Tobacco-exposed infants showed significantly poorer attention skills after birth, and the magnitude of the difference between exposed and nonexposed groups attenuated across the neonatal period. In contrast, exposure-related differences in irritable reactivity largely were not evident across the 1st month of life, differing marginally at 4 weeks of age only. Third-trimester smoking was associated with pervasive, deleterious, dose-response impacts on physical growth measured at birth, whereas nearly all smoking indicators throughout pregnancy predicted level and growth rates of early attention. The observed neonatal pattern is consistent with the neurobiology of tobacco on the developing nervous system and fits with developmental vulnerabilities observed later in life.
