Asian Americans are among the fastest growing population groups in the USA. Despite the fact that colorectal cancer (CRC) is the second most common cancer for this group, Asian Americans have low CRC screening rates. An established health promotion program, Healthy Asian Americans Project (HAAP), expanded to include community-based CRC education during 2005-2006. Using Asian-language media, HAAP promoted awareness throughout local Asian Indian, Chinese, Filipino, Hmong, Japanese, Korean, and Vietnamese American communities and recruited men and women over 50 years to attend health fairs at local community/cultural centers. Evaluation data from 304 participants in an evidence-based educational intervention showed significantly increased knowledge and attitudes about the importance of screening. Follow-up conducted between 6 and 12 months showed that 78% of those receiving the educational intervention had been screened in the last 12 months, compared with the 37% who had ever been screened with any of the tests prior to the study. This community-based health promotion program reached underserved populations and the educational intervention improved CRC screening rates. This and similar programs may help lower CRC mortality among Asian Americans.

Asian American women have the lowest mammography screening rate and are often diagnosed at later stages of breast cancer compared with other ethnic groups. This study applied the Transtheoretical Model and examined the relationships between stages of mammography adoption and mammography-related beliefs while controlling for socio-demographic factors. The study consisted of a convenience sample of 315 participants from four populous Asian ethnic groups in Michigan (109 Asian Indians, 51 Chinese, 36 Koreans and 119 Filipinos). In this relatively small sample, Koreans appeared to be more likely to be at the pre-contemplation stage and less likely to be at the maintenance stage. Perceived barriers and decisional balance scores differed by stage, with pre-contemplators reporting highest barriers and lowest scores in decisional balance. In terms of specific barrier items, pre-contemplators also displayed significantly greater agreement for most of the barrier items. Participants in the action stage have less favorable decisional balance than those in two earlier stages (i.e. contemplation and relapse). Common barriers for this sample of Asian participants included the items related to access and modesty issues. Overall, the study supports the notion that assessing differences in mammography-related beliefs by stage of screening behavior may facilitate the development of stage-matched interventions for Asian ethnic groups.

We sought to examine latent classes of family functioning and parent support trajectories during high school and whether these trajectories are associated with an increased risk of substance use and misuse among urban youth. A total of 850 adolescents (Mage = 15.1 years) were included in this study, assessed at baseline, 12-, 24-, and 36-months postbaseline, and completed self-report measures on past 30-day alcohol and marijuana use, binge drinking, and measures of family functioning and parent support. Latent class growth analysis revealed that trajectories of high family functioning and parent support are associated with a decreased risk of marijuana use. Findings may be helpful to inform family-based preventive interventions.

Background Heavy drinking is highly comorbid with nicotine and marijuana use among young adults. Yet, our knowledge about the longitudinal effects of nicotine and marijuana use (including onset timing and quantity/frequency) on heavy drinking and whether the effects vary by gender is very limited. This study aims to characterize gender-specific developmental trajectories of multiple substance use and examine gender differences in the effects of nicotine and marijuana use on heavy drinking. Methods We conducted secondary analysis on 8 waves of data from 850 high risk youth who were recruited as ninth graders with low GPA in an economically disadvantaged school district in the Midwest, and were followed up annually to young adulthood. Onset ages and quantity/frequency of multiple substance use were assessed by a self-report questionnaire at each wave. The time-varying effect model and linear mixed model were adopted for statistical analysis. Results Males’ levels of heavy drinking, nicotine use, and marijuana use tended to grow persistently from adolescence to emerging adulthood. Females, on the other hand, only gradually increased their nicotine use across time while maintaining low levels of heavy drinking and marijuana use. Controlling for the early onset status of alcohol use, early onset statuses of nicotine use and marijuana use both added additional risk for heavy drinking; late onset marijuana users were also at higher risk for heavy drinking than nonusers of marijuana. Controlling for substance use onset statuses, higher quantity/frequency of nicotine and marijuana use both contributed to more involvement in heavy drinking. We also found that the effect of nicotine use quantity on heavy drinking was greater among males. Conclusions Our study demonstrates the longitudinal effects of onset timing and quantity/frequency of nicotine and marijuana use on heavy drinking. Our analysis of gender differences also identifies female youth’s nicotine use and male youth’s co-use of nicotine and alcohol as two important areas for future prevention and intervention work.
