Objective: Screening for cancer and other chronic conditions tends to be conducted in independent programmes; that is, screening for one disease at a time. The Keelung community-based multiple disease screening programme, developed in Keelung city, Taiwan, is a notable exception. Here, we report on the Keelung programme's ethos and development within the community, focusing on equity of delivery of the service, and community involvement. In addition, we present some preliminary cost-effectiveness analyses of multiple disease screening. Methods: The Keelung programme offers screening for breast, colorectal and liver cancers, cervical and oral neoplasia, all of which have an evidence base for their efficacy, and for diabetes, hypertension, osteoporosis and hyperlipidaemia, which are of unknown efficacy. We assessed variability of coverage rates of the Keelung Community-based Integrated Screening (KCIS) programme with age and socioeconomic status, availability of facilities for referral of positive screenees, and numbers of community social workers, general practitioners and local hospitals involved in the programme. We also assessed in qualitative terms how the programme interacts with non-health agencies. Finally, we simulated activities and costs for a variety of single- and multiple-disease screening situations. Results: Between 1999 and 2003, coverage increased overall from 14.7 to 34.4%, and increased most dramatically in people aged 60–79 years (from around 30 to 60%) and in those of lower educational status (from around 40 to 70%). There was a significant growth in the involvement of social workers and volunteers in the programme, and an increase in the availability of local diagnostic and care facilities for those screened positive. In addition, there was substantial involvement of non-health agencies in publicizing the programme. In the health economic simulations, compared with no screening, the extra costs to gain an additional life year were estimated as US$667, $608, $4227 and $4789 for multiple screening with 100% attendance, multiple screening with 70% attendance, single disease screening with 100% attendance and single disease screening with 30% attendance at each programme (i.e. 74% attendance for at least one out of four programmes), respectively. Conclusions: The innovative design and outreach procedures of the KCIS have led to a growth in delivery of screening services to groups sometimes overlooked (equity), community involvement in health care (participation) and the use of non-health organizations for publicity and health education (collaboration). Simulation studies indicate that multiple disease screening may be more cost-effective than single disease screening. [ABSTRACT FROM AUTHOR]

Objective: The aims of this study were to investigate the influence of home smoking restriction (HSR) and the modified effect of parental smoking on smoking initiation among adolescents., Design: Prospective Cohort Study., Setting: Junior high school in Keelung City, Taiwan., Participants: This study collected and evaluated primary data from the Adolescent Smoking and Other Health-Related Behaviour Survey conducted in Keelung City, which aimed to investigate smoking and health-related behaviours in junior high school students (2008-2009). Data on students free of smoking in 2008 and following them until 2009 (n=901) to ascertain whether they had started smoking were analysed with logistic regression mode to examine the proposed postulates., Main Outcome Measure: The outcome variable was smoking initiation, which was defined as smoking status (yes/no) in the 2009 follow-up questionnaire. The main independent variable was HSR obtained from an adolescent self-reported questionnaire. Information on parental smoking was measured by adolescents self-reporting the smoking behaviour of their father and mother., Results: The rate of HSR was 29.79% among 7th grade adolescents. The effect of HSR on smoking initiation in adolescents was statistically significantly modified by paternal smoking (p=0.04) but not by maternal smoking (p=0.54). The effect of HSR on smoking initiation was small for fathers with the habit of smoking (OR=0.89, 95% CI (0.42 to 1.88)), but the corresponding effect size was 3.2-fold (OR=2.84, 95% CI 1.19 to 6.81) for fathers without the habit of smoking., Conclusions: Paternal smoking behaviour may play an interactive role with HSR in preventing smoking initiation among Taiwanese adolescents., (Published by the BMJ Publishing Group Limited.

We aimed to investigate the associations between three smoking-related constructs (pros and cons of smoking, temptation to smoke, and self-efficacy of resisting smoking) and stage of change (precontemplation, contemplation, preparation, and action) based on the transtheoretical model among smokers attending a community-based screening program. We also assessed their effects on long-term all-cause mortality. A prospective cohort study, with an average of 7 years of follow-up, was conducted by enrolling 454 male smoking screenees. The comparisons of the mean score of each variable pertaining to three smoking-related constructs across four stages of smoking cessation were assessed by analysis of variance. The impacts of both smoking-related constructs and smoking cessation stage measured at baseline on 7-year mortality were assessed by using proportional hazards regression model. The differences in the mean scores of pros and cons of smoking, temptation to smoke, and self-efficacy of resisting smoking across four stages of smoking cessation were statistically significant (P < 0.01). The precontemplation group and the contemplation group as opposed to the action group increased the risk for all-cause mortality, but the size of effect was not statistically significant (P = 0.39) when age, duration of smoking, and three smoking- related constructs were controlled. Those with a lower social aspect of self-efficacy were approximately threefold [adjusted hazard ratio = 3.22 (95 % CI 1.26-8.21)] risk for all-cause death compared with those with a higher one. Three smoking-related constructs were highly associated with smoking cessation stage, and low self-efficacy was independently predictive of long-term mortality among male smokers attending a community-based screening program.

Aims: To estimate the prevalence and severity of periodontal disease (PD) in the Taiwanese population aged 35-44 years and to investigate the association between demographic factors and PD., Materials and Methods: Between 2003 and 2005, residents of Keelung of the appropriate age were invited to screening. The community periodontal index (CPI) and loss of attachment (LA) index were used to measure the periodontal status at subject (prevalence) and sextant levels (severity). Basic demographic information was also collected by a questionnaire., Results: Of 8462 enrollees, 94.8% had some signs of PD, of whom 29.7% had periodontal pockets >3 mm and 35% LA >3 mm. Calculus was the most common problem in terms of both prevalence (49.6%) and severity (affecting an average of 3.0 sextants per person). Risk factors for poor periodontal status (as measured by CPI) were older age (odds ratio, OR: 1.44), male gender (OR: 2.70), low education level (OR: 1.40), and being a manual worker (OR: 1.51). Similar findings were observed for LA., Conclusion: The prevalence of PD in 35-44-year-olds was found to be high in this large community-based study of screening for PD with CPI and LA. Poorer periodontal health was observed in males, the less educated, and manual workers.
