Diabetes programmes include community health workers as team members in a variety of roles. There are some preliminary data demonstrating improvements in participant knowledge and behaviour. Much additional research, however, is needed to understand the incremental benefit of community health workers in multicomponent interventions and to identify appropriate settings and optimal roles for community health workers in the care of persons with diabetes.

Introduction: Smoking prevalence is high among limited English-proficient Chinese and Vietnamese American men, who are frequently unmotivated to quit and who underutilize smoking cessation resources. This study applied lay health worker outreach to leverage peer and family networks to promote smoking cessation among these men. Methods: We integrated qualitative formative research findings and Social Network Theory to develop a social-network family-focused intervention. In a pilot single-group trial, 15 lay health workers recruited 96 dyads (N = 192, 75% Vietnamese) of Chinese or Vietnamese male daily smokers and their family members and delivered the intervention consisting of two small group education sessions and two individual telephone calls over 2 months. Results: At baseline, 42% of smokers were at precontemplation. At 3 months following the initiation of the intervention, 7-day and 30-day point prevalence smoking abstinence rates as reported by smokers and independently corroborated by family members were 30% and 24%, respectively. Utilization of smoking cessation resources (medication, quitline, physician's advice) increased from 2% to 60% (P < .001). Findings showed high acceptability of the intervention as it facilitated learning about tobacco-related health risks and cessation resources, and communications between smokers and their families. Conclusions: This novel social network family-focused intervention to promote smoking cessation among Chinese and Vietnamese smokers appears to be acceptable, feasible, and potentially efficacious. Findings warrant evaluation of long-term efficacy of the intervention in a larger scale randomized controlled trial.

Background Vietnamese-American women underutilize breast cancer screening. Design An RCT was conducted comparing the effect of lay health workers (LHWs) and media education (ME) to ME alone on breast cancer screening among these women. Setting/participants Conducted in California from 2004 to 2007, the study included 1100 Vietnamese-American women aged ≥40 years who were recruited through LHW social networks. Data were analyzed from 2007 to 2009. Intervention Both groups received targeted ME. The intervention group received two LHW educational sessions and two telephone calls. Main outcome measures Change in self-reported receipt of mammography ever, mammography within 2 years, clinical breast examination (CBE) ever, or CBE within 2 years. Results The LHW+ME group increased receipt of mammography ever and mammography in the past 2 years (84.1% to 91.6% and 64.7% to 82.1%, p<0.001) while the ME group did not. Both ME (73.1% to 79.0%, p<0.001) and LHW+ME (68.1% to 85.5%, p<0.001) groups increased receipt of CBE ever, but the LHW+ME group had a significantly greater increase. The results were similar for CBE within 2 years. In multivariate analyses, LHW+ME was significantly more effective than ME for all four outcomes, with ORs of 3.62 (95% CI=1.35, 9.76) for mammography ever; 3.14 (95% CI=1.98, 5.01) for mammography within 2 years; 2.94 (95% CI=1.63, 5.30) for CBE ever; and 3.04 (95% CI=2.11, 4.37) for CBE within 2 years. Conclusions Increased breast cancer screening by LHWs among Vietnamese-American women. Future research should focus on how LHWs work and whether LHW outreach can be disseminated to other ethnic groups.

IntroductionPopulation-based studies have reported high rates of smoking prevalence among Chinese and Vietnamese American men. Although nicotine replacement therapy (NRT) is effective, recommended, and accessible without prescription, these populations underuse NRT for smoking cessation. The aim of this study was to assess understanding and use of NRT and nonpharmacologic treatments among Chinese and Vietnamese American male smokers and their families.MethodsIn-depth qualitative interviews were conducted with 13 smoker–family pairs, followed by individual interviews with each participant. A total of 39 interviews were conducted in Vietnamese or Chinese, recorded, translated, and transcribed into English for analysis.ResultsFour themes were identified: use and understanding of NRT, nonpharmacologic strategies, familial and religious approaches, and willpower. Both smokers and their family members believed strongly in willpower and a sense of personal responsibility as the primary drivers for stopping smoking. Lack of these 2 qualities keeps many Chinese and Vietnamese men from using NRT to quit smoking. Those who do use NRT often use it incorrectly, following their own preferences rather than product instructions.ConclusionOur findings indicate the importance of culturally appropriate patient education about NRT. It may be necessary to teach smokers and their families at an individual level about NRT as a complementary approach that can strengthen their resolve to quit smoking. At a community level, public health education on the indication and appropriate use of evidence-based smoking cessation resources, such as NRT, would be an important component of effective tobacco control.
