Cancer is a serious public health problem worldwide, and its relationship
with affective disorders is not clear.
To investigate alcohol- and tobacco-related cancer risk among patients
with affective disorders in a large Taiwanese cohort.
Records of newly admitted patients with affective disorders from January
1997 through December 2002 were retrieved from the Psychiatric Inpatient
Medical Claims database in Taiwan. Cancers were stratified by site and
grouped into tobacco- or alcohol-related cancers. Standardised incidence
ratios (SIRs) were calculated to compare the risk of cancer between those
with affective disorders and the general population.
Some 10 207 patients with bipolar disorder and 9826 with major depression
were included. The risk of cancer was higher in patients with major
depression (SIR = 2.01, 95% CI 1.85–2.19) than in those with bipolar
disorder (SIR 1.39, 95% CI 1.26–1.53). The elevated cancer risk among
individuals ever admitted to hospital for affective disorders was more
pronounced in tobacco- and/or alcohol-related cancers.
Elevated cancer risk was found in patients who had received in-patient
care for affective disorders. They require holistic approaches to
lifestyle behaviours and associated cancer risks.
Repeat self-harm is an important risk factor for suicide. Few studies have explored risk factors for non-fatal repeat self-harm in Asia.
To investigate the risk of non-fatal repeat self-harm in a large cohort of patients presenting to hospital in Taipei City, Taiwan.
Prospective cohort study of 7601 patients with self-harm presenting to emergency departments (January 2004–December 2006). Survival analysis was used to examine the rates, timing and factors associated with repeat self-harm.
In total 778 (10.2%) patients presented to hospital with one or more further episodes of self-harm. The cumulative risk of non-fatal repetition within 1 year of a self-harm episode was 9.3% (95% CI 8.7–10.1). The median time to repetition within 1 year was 105 days. Females had a higher incidence of repeat self-harm than males (adjusted hazard ratio 1.25, 95% CI 1.05–1.48) but males had shorter median time to repetition (107 v. 80 days). Other independent risk factors for repeat self-harm within 1 year of an index episode were: young age, self-harm by medicine overdose and increasing number of repeat episodes of self-harm.
The risk of non-fatal repeat self-harm in Taipei City is lower than that seen in the West. Risk factors for repeat non-fatal self-harm differ from those for fatal self-harm. The first 3 months after self-harm is a crucial period for intervention.
Most previous studies of long-term mortality risk following self-harm
have been conducted in Western countries with few studies from Asia.
To investigate suicide and non-suicide mortality after non-fatal
self-harm in Taipei City, Taiwan.
Prospective cohort study (median follow-up 3.3 years) of 7601 individuals
presenting to hospital with self-harm (January 2004 to December 2006).
Standardised mortality ratios (SMRs) for suicide and non-suicide
mortality were calculated.
Suicide risk in the year following self-harm was over 100 times higher
than in the general population (SMR = 119.6, 95% CI 99.6–142.5). Males
and middle-aged and older adults had the highest subsequent risk of
suicide. Compared with people who took an overdose, individuals who used
hanging or charcoal burning in their index episode had the highest risk
of suicide. For non-suicide mortality the SMRs were 6.7 (95% CI 5.7–7.8)
in the first year and 4.4 (95% CI 3.9–4.9) during the whole follow-up
Patterns of increased all-cause and suicide mortality following an
episode of self-harm are similar in Taipei City to those seen in Western
countries. Designing better aftercare following non-fatal self-harm,
particularly for those with underlying physical disorders or who have
used lethal self-harm methods, should be a priority for suicide
prevention programmes in Asia.
All suicides (n=12 497) in Taiwan in 2001–2004 were identified from mortality records retrieved from the National Health Insurance Database. Altogether, 95.1% of females and 84.9% of males had been in contact with healthcare services in the year before their death. Females received significantly more diagnoses of psychiatric disorders (48.0% v. 30.2%) and major depression (17.8% v. 7.4%) than males. Such differences were consistent across different medical settings where contact with hospital-based non-psychiatric physicians was as common as with general practitioners (GPs). However, diagnoses of psychiatric disorders were underdiagnosed in both genders.
Although teachers are the key participants in health-promoting schools (HPS) programme delivery, it is still unknown whether teachers are appropriate health information resources and role models for students with respect to healthy diets. The present study aimed to investigate the effects of implementing HPS programmes on teachers’ nutrition knowledge and diets.
One HPS programme aiming at dietary intervention (HP-D) and one HPS not aiming at dietary intervention (HP-ND) were selected, along with two non-health-promoting (NHP) schools matched for school size and urbanization level with the two HPS. All 361 teachers in the four schools were invited to participate, yielding a 78·4 % overall valid response rate. A structured, self-reported questionnaire was administered, with regression models used for statistical analysis.
Teachers in the HP-D group had a mean score of 21·1 on a range of 0–30 for nutrition knowledge, which was significantly higher than the mean scores of 18·5 in the HP-ND group and 19·1 in the NHP group (P < 0·001). Better dietary behaviours were also observed among HP-D teachers. Further, being a ‘health education’ course instructor was associated with significantly higher scores on nutrition knowledge (β = 2·6, P < 0·001) and vegetable and fruit consumption (β = 1·4, P = 0·02) in the HP-D group than in the NHP group. The HP-ND and NHP groups exhibited similar patterns of non-significant differences compared with the HP-D group.
Implementation of a coordinated HPS framework on nutrition and diet was positively correlated with schoolteachers’ nutrition knowledge and dietary intake.
To evaluate the effect on decrease in blood pressure of modifying risk factors for stroke, such as blood lipid profiles, diet habits and indices of body weight, through a family-based nutrition health education programme among hypertensive patients and pre-hypertensive subjects without taking any antihypertensive drugs.
Design and setting
This was a community-based prospective study. The study population was randomly selected from communities in Taipei; potential subjects were invited by telephone to participate.
After excluding subjects whose blood pressure was normal and those using antihypertensive drugs, there were 390 participants included in the study. Subjects in the intervention group (n 293) received nutrition health education on blood pressure control and stroke-related risk factor modification at each visit. Non-intervention subjects (n 97) only acquired a general education sheet available in clinics. The blood pressure of study subjects was measured at baseline and 6-month follow-up to evaluate the intervention’s effect on decrease in blood pressure.
Significant decreases of 2·0 mmHg and 5·9 mmHg in systolic blood pressure were observed both in pre-hypertensive and hypertensive subjects in the intervention group. Additionally, intervention subjects with improvement of total cholesterol and LDL cholesterol, decrease in indices of body weight and increase in consumption of fruit and vegetables also had significant lowering of blood pressure.
The present study provided evidence that the blood pressure of pre-hypertensive and hypertensive subjects could decrease significantly, without taking antihypertensive drugs, after modifying blood lipid profiles and waist by dietary habits changed through a family-based nutrition heath education programme, resulting in a significant effect on stroke risk reduction.
An integrated optical method for measuring deformation of micro-mechanical systems with better than sub-micron resolutions is detailed. Both a confocal laser scanning microscope and a photon tunneling microscope were integrated into a single microscopy system due to their complimentary capabilities for examining sub-micrometer deformations. A halogen lamp and laser were adopted as the two light sources for the measurements. Since topographic information of samples up to a 15μm by 15μm area can be measured, a three-dimensional displacement field of the sample was extracted by comparing topographies of the same specimen area before and after deformation. The bending and twisting deformation of a micro-mirror driven by the electrostatic force was measured to demonstrate the capability of this newly developed instrument. The experimental data obtained agrees reasonably well with the theoretical results calculated by adopting an analytical solution and a finite element method. The small discrepancy in the result can be traced to the surface roughness effect, which is often non-negligible in micro-systems.
