Background: Smoking is a risk factor for lung cancers, and a myriad of other acute and chronic ailments. The purpose of this study was to predict initiation and sustenance of smoking cessation among smokers using a fourth-generation behavioral framework, multi-theory model (MTM) of health behavior change. Methods: A convenience sample of smokers from a shopping mall in rural, Appalachian Kentucky county was invited to participate in this cross-sectional study. A 38-item, face and content validated, MTM-based survey instrument was administered to the participants. Results: A total of 148 participants completed the study. The mean age of the participants was 35.53 (SD = 14.52) years. Most were male (58.1%) and Caucasian (95.9%). Participants reported smoking for an average of 16.45 (SD = 13.12) years. Participatory dialogue (β = 0.235, P = .003) and behavioral confidence (β = 0.305, P = .005) were significant predictors of intention for initiation for smoking cessation behavior. Emotional transformation (β = 0.319, P = .001) was a significant predictor of intention for sustenance for smoking cessation behavior. Discussion: Two of the MTM constructs for initiation and one of the MTM constructs for sustenance of change accounted for a moderate amount of variance in initiation and sustenance of smoking cessation behavior among community members in a rural, Kentucky county. MTM has utility for predicting both initiation and sustenance of smoking cessation behavior. Future interventions using MTM constructs should be developed for smoking cessation behavior change.

Survey results showed that the MTM is a useful framework for designing behavior change interventions to promote fruit and vegetable consumption among college students.

Skin cancers are becoming a substantial public health problem in China. Fair skin and increased exposure to ultraviolet B (UVB) rays from the sun are among the most substantial risk factors for skin cancer development, thus making the Chinese people vulnerable to this group of diseases. The purpose of this article is to present a narrative review of the knowledge, attitudes, and practices (KAP) related to skin cancers within the Chinese population. A systematic electronic search of MEDLINE (PubMed), CINAHL, ScienceDirect, and Google Scholar databases yielded nine articles that met the inclusion criteria. The review found that although sunscreen application was a commonly used method of skin protection among the general Chinese population, educational interventions enhancing current knowledge and attitudes about the effects of UVB rays on skin from undue sun exposure were limited in many smaller communities of the country. Hence, there is an essential need to design effective, evidence-based educational programs promoting sun protection behaviors in both congregated and sparsely populated areas of China.

Context: The multitheory model (MTM) is a newly developed fourth-generation theoretical framework that addresses both initiation and sustenance of health behavior change. Studies have shown that the MTM is efficacious in predicting a range of health behaviors. Objective: To assess the utility of the MTM in predicting initiation and sustenance of physical activity behavior among osteopathic medical students. Methods: In this cross-sectional study, a volunteer convenience sample was recruited from an osteopathic medical school student population at a university in the southeastern region of the United States. An online survey was used to collect self-reported data on sociodemographic information and MTM constructs. Multiple linear regression using the enter method for modeling was performed to determine the predictive ability of the MTM constructs. Results: Of the 135 participants, 52.6% were women and 67.7% were white. The initiation model explained 25.8% of the variance (adjusted R 2 =0.238). Behavioral confidence was a statistically significant predictor of initiation of physical activity behavior change. The sustenance model explained 41.7% of the variance (adjusted R 2 =0.402). Changes in social environment and emotional transformation were statistically significant predictors of sustenance of physical activity behavior change. Conclusion: The MTM appears to be a robust theoretical framework for designing behavior change interventions to increase physical activity among osteopathic medical students.
