Stages of change, determinants, and mortality for smoking cessation in adult Taiwanese screenees.

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.

Mortality and suicide after self-harm: community cohort study in Taiwan.

BACKGROUND: Little is known about outcomes after self-harm in East Asia. AIMS: To investigate mortality after self-harm in a Taiwanese population. METHOD: Between 2000 and 2003, 1083 individuals who self-harmed were identified through a population self-harm register in Nantou County, Taiwan, and followed until 2007 for date and cause of death on a national mortality database. RESULTS: In total, 145 individuals died, 48 through suicide. The risks of all-cause and suicide mortality in the first year were 4.7% and 2.1% respectively, representing 8- and 131-fold age- and gender-standardised increases. Male gender and older age were independent risk factors for both suicide and non-suicide mortality. Use of more lethal methods in the index episode was associated with higher mortality but this was accounted for by gender. CONCLUSIONS: Results in this sample support the recommendation that people with a history of recent self-harm should be a major target for suicide prevention programmes.

Non-fatal repetition of self-harm: population-based prospective cohort study in Taiwan.

BACKGROUND: Repeated self-harm is relatively common and is linked with an elevated risk of eventual suicide. There has been no study of this involving a large sample from the Far East. AIMS: To estimate the risk over the medium term of non-fatal repetition of self-harm and identify predictive factors in those carrying out self-harm. METHOD: A total of 970 individuals who had self-harmed were recruited from a community-based suicide behaviour register system in Nantou, Taiwan from July 2000 to February 2003. Information regarding demography and suicide methods was collected. Individuals were followed-up until December 2005 to examine the risk of repeated self-harm and independent predictive factors. RESULTS: Ninety cohort members had repeated self-harm during the follow-up period (accounting for 131 repeated self-harm episodes in all). The cumulative risks were 5.7% for the first year, 7.8% for the second year and 9.5% for the fourth year. The risk was highest within the first year after the self-harm event. Independent risk factors included female gender and self-cutting as well as self-poisoning with drugs. Effect of younger age was mediated through the choice of methods. CONCLUSIONS: Individuals with self-harm have a high risk of repetition, especially within the first year. Suicide prevention strategies need to focus on intervening with this population to reduce their repetition.

Seroprevalence and sources of Toxoplasma infection among indigenous and immigrant pregnant women in Taiwan.

Investigation on seroprevalence and risk factors of Toxoplasma gondii infections among indigenous and immigrant pregnant women in Mid-Taiwan showed that anti Taxoplasma-specific IgG antibody counts were significantly higher in indigenes (40.6%) than in immigrants (18.2%), with an odds ratio of OR=3.34 (95% CI: 1.93-4.80). The titre of Taxoplasma-specific IgG was also significantly higher in indigenes than in immigrants (P<0.001). Differences of living styles for Toxoplasma infection between the two groups were drinking untreated water (OR=2.34, 95% CI: 1.36-4.02), consumption of raw/undercooked meats (OR=10.11 95% CI: 4.92-20.78), especially raw/undercooked pork (P=0.000), or raw/undercooked viscera (OR=9.16, 95% CI: 2.97-27.94), contact with cats (OR=5.69, 95% CI: 2.83-11.47), or soil (OR=2.55 95% CI: 1.72-3.80). Differences of risk factors for Toxoplasma infection in terms of positive IgG in the two groups were consumption of raw/undercooked meats (P=0.005) especially raw/undercooked pork (P=0.004), and contact with cats (P=0.013) or soil (P=0.028). It is concluded that seroprevalence of Toxoplasma infection is higher in indigenous pregnant women and related to their living styles. To prevent congenital toxoplasmosis, health education seems required.

Long-term psychological outcome of 1999 Taiwan earthquake survivors: a survey of a high-risk sample with property damage.

OBJECTIVE: Severe natural disasters can cause long-term psychological impact on the survivors. This study aimed to examine the prevalence and risk factors of posttraumatic stress symptoms and psychiatric morbidity among survivors of the severe earthquake that occurred in Chi-Chi, Taiwan, in September 21, 1999. METHODS: A total of 6412 earthquake survivors whose houses were destroyed by earthquake were recruited about 2 years after the disaster. They completed a self-report questionnaire assessing posttraumatic stress symptoms, psychiatric morbidity, and information of demographics, trauma exposure, and current living status. RESULTS: The estimated rates of posttraumatic stress disorder caseness and psychiatric morbidity were 20.9% and 39.8%, respectively. Psychiatric morbidity occurred mainly in survivors who were female, older, with low education level, and currently living in a prefabricated house. The risk factors for posttraumatic stress disorder caseness were female sex, currently living in a prefabricated house, low education level, and experienced complete destruction of property. CONCLUSION: These results showed that severe earthquake can cause long-term psychological impact in the survivors. The findings of risk factors suggest avenues for targeting postdisaster interventions.

Preliminary study of the effect of low-intensity home-based physical therapy in chronic stroke patients.

This study was a preliminary examination of the effect of low-intensity home-based physical therapy on the performance of activities of daily living (ADL) and motor function in patients more than 1 year after stroke. Twenty patients were recruited from a community stroke register in Nan-Tou County, Taiwan, to a randomized, crossover trial comparing intervention by a physical therapist immediately after entry into the trial (Group I) or after a delay of 10 weeks (Group II). The intervention consisted of home-based physical therapy once a week for 10 weeks. The Barthel Index (BI) and Stroke Rehabilitation Assessment of Movement (STREAM) were used as standard measures for ADL and motor function. At the first follow-up assessment at 11 weeks, Group I showed greater improvement in lower limb motor function than Group II. At the second follow-up assessment at 22 weeks, Group II showed improvement while Group I had declined. At 22 weeks, the motor function of upper limbs, mobility, and ADL performance in Group II had improved slightly more than in Group I, but the between-group differences were not significant. It appears that low-intensity home-based physical therapy can improve lower limb motor function in chronic stroke survivors. Further studies will be needed to confirm these findings.
