Background: Media guidelines for suicide reporting are available in many countries. However, to what extent the mass media comply with the guidelines is unknown. Few studies are available that investigate systematically whether the mass media reflect the epidemiological reality of suicide deaths in their articles. Methods: Based on the WHO media guidelines, this study investigated the characteristics of newspaper articles of suicides in three Chinese communities, namely Hong Kong, Taiwan and Guangzhou. Epidemiological comparisons were conducted to identify the age and gender differences between the suicide victims as reported in the newspapers and the official records of suicide deaths in all three places. Results: The results found that one media characteristic complied with the WHO media guidelines (ie, only about 2% of the articles were printed on the front page), but there were a number of instances of non-compliance (ie, only 4--14% provided sources for help-seeking and 27--90% printed with photos). The epidemiological comparisons revealed an over-representation of younger suicides and an under-representation of late-life suicides in the newspapers of all three places. Furthermore, female suicides were found to be under-reported in Taiwan and Guangzhou newspapers, but not in Hong Kong papers. Conclusion: Non-compliant suicide articles are prevalent in the newspapers of these three Chinese settings. The observed media misrepresentations may potentially mislead the public and the policy makers about the actual risk for suicide in some demographic groups. [ABSTRACT FROM AUTHOR]

Background: Second-hand smoke SHS) exposure is a modifiable cause of ill health. Despite the smoking ban in public places introduced in Hong Kong in 2007, infants and children continue to be exposed within the home. Aims: To determine the critical windows of SHS exposure and the duration of its impact on serious infectious morbidity in the first 8 years of life. Methods: The Hong Kong "Children of 1997" birth cohort is a prospective, population-based study of 8327 children comprising 88% of all births in April and May 1997, of whom 7402 (89%) were followed up until their eighth birthday in 2005. We used multivariable Cox regression to assess the relation between postnatal SHS exposure and risk of first admission to public hospitals (together accounting for >95% total bed-days overall) for respiratory, other and all infections from birth to 8 years of age, for all individuals and for vulnerable subgroups. Results: Overall, household SHS exposure within 3 metres in early life was associated with a higher risk of admission for infectious illness up until 8 years of age (hazard ratio 1.14, 95% Cl 1.00 to 1.31), after adjustment for sex, birthweight, gestational age, feeding method, maternal age, highest parental education and proxies of preferred service sector. The association was strongest in the first 6 months of life (HR 1.45, 95% Cl 1.15 to 1.83). In vulnerable subgroups such as premature babies, the association held through to 8 years of age (HR 2.00, 95% Cl 1.08 to 3.72). Infants exposed to SHS in the first 3 months of life were most vulnerable to infectious causes of hospitalisation. Conclusion: Household SHS exposure in early infancy increases severe infectious morbidity requiring hospital admission. Reducing SHS exposure in infants and particularly in more vulnerable infants will lower the bed-days burden due to infectious causes. [ABSTRACT FROM AUTHOR]

Objective: To assess the prevalence and reasons for non-use of condoms among the Hong Kong Chinese population and obtain baseline data to monitor sexual behavioural change.Methods: Cross sectional self administered questionnaire surveys in convenience sampled groups of Hong Kong Chinese residents were carried out.Results: Of the 1508 respondents, 24% reported consistent condom use and 76% inconsistent use. Overall, 17% of respondents reported having sex with strangers. People who were at increased risk for inconsistent condom use included STD clinics attendees, those who never married, and those reporting low self efficacy for condom use or sex with strangers. Common reasons for not using condoms were trust in partner, use of other contraceptives, and reduced sensation while using condoms.Conclusions: Given the reported high prevalence of travel and sexual contact with strangers, and misconceptions about condoms among the Hong Kong Chinese population, innovative condom social marketing campaigns are needed. Periodic monitoring of condom use behaviours should be an integral part of HIV/STD surveillance activity. [ABSTRACT FROM AUTHOR]

Background Health professionals including psychiatrists were reported to have stigmatising opinions on psychiatric patients. Their views may be affected by clinical, social and cultural factors. Objective This study explored the views of Chinese psychiatrists on stigmatisation of psychiatric patients. Methods Focus group discussions with psychiatrists were conducted in Hong Kong. Their views towards stigmatisation of psychiatric patients and strategies to reduce stigmatisation were discussed. Findings The psychiatrists perceived the clinical needs to classify the patients according to the diagnoses and they did not see it as stigmatisation. They believed that some mental illnesses are characterised with violence or deviance, and were not completely curable. Instead of trying to eliminate stigma, they managed in ways that took social expectations into consideration. They might offer a relative vague diagnostic label to save the 'face' of the patients and secure greater acceptance for the illness from the public. They tended to accept family members to make decisions on behalf of the patients. Reconciling public interest and patients' autonomy, they encouraged stable psychotic patients to live in the community but agreed to institutionalise those patients with violent behaviours. Conclusion While the psychiatrists argued that the diagnosis was not a form of stigma, they were sensitive enough and framed responses to patients in ways to minimise stigma. They tended to believe that stigma was inevitable given the nature of some psychotic disorders. Disguising the stigma appeared to be the common approach to deal with stigma in a Chinese context. Clinical Implications The psychiatrists, especially those practicing in a Chinese context, may consider a wider perspective of community mental health rehabilitation which is not limited to social stability but also social life.

The author discusses the smoking prevalence data in Hong Kong, China and the move to prevent the possible increase and burden due to smoking.

Smoking scenes in movies, exploited by the tobacco industry to circumvent advertisement bans, are linked to adolescent smoking. Recently, a Hong Kong romantic comedy Love in a puff put smoking at centre stage, with numerous smoking scenes and words that glamourise smoking. Although WHO has issued guidelines on reducing the exposure of children to smoking in movies, none is adopted in Hong Kong. Comprehensive tobacco control strategies are urgently needed to protect young people in Hong Kong from cigarette promotion in movies. [ABSTRACT FROM AUTHOR]

Background In March 2007, the Hong Kong Government halved its heavy excise taxes on beer and wine, and 1 year later, it eliminated all duties on these beverages. This study examines the impact of such duty reductions on cardiovascular disease (CVD)-related mortality among the elderly in Hong Kong. Methods Box-Jenkins autoregressive integrated moving average intervention time series analyses were applied to monthly morality data from 2001 to 2010 to quantify the impacts of duty reduction and exemption on CVD death rates among those aged 65 years or older. Results The alcohol duty reduction in March 2007 was associated with an estimated 13% increase (95% CI 2% to 24%) in CVD death rates among elderly men, after controlling for the other intervention, outlier, trends and seasonal variations. This was equivalent to an extra 11 CVD deaths per 100 000 elderly men each month. Much of the observed impacts on CVD death rates were found to have contributed only by that on ischaemic heart disease mortality (18% increase in rate for men (95% CI 4% to 34%); 15% increase for women (95% CI 0.4% to 31%)), not by mortality due to stroke or hypertension. The alcohol duty exemption on March 2008 was not found to have impacted the CVD death rates. Conclusions The increase in CVD death rates among the Chinese elderly after alcohol duty reduction suggest that the purported beneficial effect of moderate alcohol use may not apply to certain Chinese populations, adding fuel to the ongoing debate on the risks and benefits of moderate alcohol consumption on mortality.

Objective To assess the perceived effectiveness of cigarette health warnings in China, compared with picture and text-only warnings from other countries. Method 1169 individuals (adult smokers, adult nonsmokers and youth) from four Chinese cities (Beijing, Shanghai, Kunming and Yinchuan) viewed 10 health warnings on cigarette packages, which included (a) the current Chinese text warnings covering 30% of the front/back of the pack (introduced October 2008); (b) the former Chinese text warning located on the side of the pack; (c) four picture warnings covering 50% of the front/back of the pack from Canada (lung cancer), Singapore (mouth disease), Hong Kong (gangrene) and European Union (clogged arteries); and (d) the same four warnings without the picture. Participants rated and ranked the 10 warnings on dimensions including how effective each would be in motivating smokers to quit and in convincing youth not to start smoking. Results Both Chinese warnings were consistently rated as least effective, with the new Chinese warning rated only slightly higher than the old warning. The picture warnings were consistently ranked or rated as most effective, with the text-only versions in the middle. Results were consistent across subject group, city and sex. Conclusions (1) Picture warnings are rated as much more effective than the same warnings without pictures. (2) The revised health warnings in China, introduced in October 2008, are only marginally more effective than the previous warning and far less effective than even text warnings from other countries. These results, coupled with population-based evaluation studies, suggest that pictorial warnings would significantly increase the impact of health warnings in China. [ABSTRACT FROM PUBLISHER]

Background: Setting physical barriers, for example platform screen doors (PSDs), has been proven to be effective in preventing falls onto railway tracks, but its cost-effectiveness is not known. For economic evaluation of public health interventions, the importance of including non-health factors has been noted despite a lack of empirical studies. This study aimed to investigate the effectiveness and cost-effectiveness of PSDs, which are installed in part of the Hong Kong railway system, for preventing railway injuries. Methods: Data on railway injuries from 1997 to 2007 were obtained from the railway operators. Poisson regression was used to examine the risk reduction. Two incremental cost-effectiveness ratios (ICER) were calculated to assess the cost-effectiveness based on (1) disability-adjusted life years (DALYs) only and (2) DALYs with potential fare revenue and passengers' waiting time lost due to railway circulation collapse. Results: The PSD installation has effectively reduced railway injuries (adjusted 5-year average percentage change: --68.8%, p<0.0001) with no apparent substitution effect to the other platforms observed. To be cost-effective, the cost of gaining a healthy life year (ICER) should not exceed three times the per capita GDP (US$74 700). The PSD installation would only be cost-effective if the loss of fare revenue and passengers' waiting time, in addition to DALY, were included (ICER: US$65 400), while the ICER based on DALY only would be US$77 900. Conclusion: The challenges of complexity for economic evaluation appear in many community-based health interventions. A more extensive perspective for exploring other outcome measurements and evaluation methods to reflect a fair and appropriate value of the intervention's cost-effectiveness is needed.

Background Existing studies have described a strong correlation between unemployment rates and suicide rates, but the exact mechanisms through which they may interact with one another remain unknown. Method This study examined the complex relationships between suicide rates and both regional unemployment rates and individual employment status during times of economic recession (2000-3) and recovery (2003-6) in Hong Kong. Results Despite the strong correlation (0.86) between the unemployment rates and suicide rates for 2000e6, the rates of suicides within the employed and unemployed groups moved in the opposite direction from the overall population trend. That is, the suicide rate among the unemployed decreased during economic recession and increased during recovery. Conclusion It is important to be able to distinguish precisely between population-level concepts, such as rates, and individual-level characteristics, such as employment status, when considering the development of evidence-based suicide prevention strategies.

Background Research on trends in cancer incidence has usually examined single sites in populations that long ago completed the economic transition. The trends in 11 cancers in three groups in the recently transitioned Hong Kong Chinese population were examined to delineate the effects of economic transition and provide generalized aetiological insights. Methods Sex-specific Poisson models were fitted to cancer incidence in Hong Kong (1974-2003) to examine age, period and birth cohort effects. Cancers were grouped as: hormonally modulated (including breast, endometrium, ovary and prostate), infection-related (cervix, liver, nasopharynx, lymphoma and stomach) and lifestyle-related (colorectum and lung). Results Age-standardised incidence of hormonally modulated female cancers increased for the first generation (women born ~ 1940) to experience puberty in the transitioning environment of Hong Kong. Prostate cancer incidence increased, despite a downturn for the first generation growing up in Hong Kong. Incidence of infection-related cancers decreased, mainly due to birth cohort effects; coinciding with birth for liver cancer and lymphoma, with reaching adulthood for cervical and male nasopharyngeal cancers, and with a generation for stomach cancer. Lifestyle-related cancers had sex-specific declines by birth cohort. Conclusion With economic transition and the associated lifestyle changes, environmentally determined levels of pubertal female hormones may drive intergenerational increases in hormonally related female cancers. Economic development, via improved living conditions, may also reduce infection-related cancers, possibly including prostate cancer; however, the effects depend on transmission dynamics and perhaps specific public health initiatives. In traditional societies, males may benefit from economic development sooner than females. [ABSTRACT FROM AUTHOR]

Background: Although the harms of smoking are well established, it is unclear how they extend into old age in the Chinese. Aim: To examine the relationship of smoking with all-cause and major cause-specific mortality in elderly Chinese men and women, respectively, in Hong Kong. Methods: Mortality by smoking status was examined in a prospective cohort study of 56 167 (18 749 men, 37 416 women) Chinese aged ≥ 65 years enrolled from 1998 to 2000 at all the 18 elderly health centres of the Hong Kong Government Department of Health. Results: After a mean follow-up of 4.1 years, 1848 male and 2035 female deaths occurred among 54 214 subjects (96.5% successful follow-up). At baseline, more men than women were current smokers (20.3% vs 4.0%) and former smokers (40.8% vs 7.9%). The adjusted RRs (95% CI) for all-cause mortality in former and current smokers, compared with never smokers, were 1.39 (1.23 to 1.56) and 1.75 (1.53 to 2.00) in men and 1.43 (1.25 to 1.64) and 1.38 (1.14 to 1.68) in women, respectively. For current smokers, the RRs (95% CI) for all-cause mortality were 1.59 (1.39 to 1.82), 1.72 (1.48 to 2.00) and 1.84 (1.43 to 2.35) for daily consumption of 1-9, 10-20 and > 21 cigarettes, respectively (p for trend < 0.001 ). RRs (95% CI) were 1.49 (1.30 to 1.72) and 2.20 (1.88 to 2.57) in former and current smokers for all deaths from cancer, and 1.24 (1.04 to 1.47) and 1.57 (1.28 to 1.94) for all cardiovascular deaths, respectively. Quitters had significantly lower risks of death than current smokers from all causes, lung cancer, all cancers, stroke and all cardiovascular diseases. Conclusions: In old age, smoking continues to be a major cause of death, and quitting is beneficial. Smoking cessation is urgently needed in rapidly ageing populations in the East.

Background: The Health Promoting School (HPS) is a WHO sponsored framework, compiled to enable education and health sectors to be more effective in school based initiatives. Aims: This study attempted to test the hypothesis that students from schools that had comprehensively embraced the HPS concept as indicated by the Healthy School Award, were better, in terms of health risk behaviour, self reported health status, and academic results, than students from schools that did not reach the standard of the award. Methods and Results: The results presented came from nine schools (four primary and five secondary) applying for accreditation of the Healthy Schools Award after adopting the HPS framework for two years. Regular consultancy support and training were available to all schools. Students had completed before and after surveys to assess their health behaviours, self reported health status, and academic standing before the two year intervention, and at its end. Data from the before and after surveys of the students attending schools that reached certain level of HPS standard as indicated by the award, were compared with students whose schools did not receive the award, and the results showed differences. Some differences were found to be more significant among the primary school students than secondary schools students. This illustrated early intervention for lifestyle changes to be more effective. Students' satisfaction with life also improved if their schools adopted the concept of HPS comprehensively. Conclusions: The results suggest that comprehensive implementation of HPS would contribute to differences in certain behaviours and self reported health and academic status. [ABSTRACT FROM AUTHOR]

Background: Costs of tobacco-related disease can be useful evidence to support tobacco control. In Hong Kong we now have locally derived data on the risks of smoking, including passive smoking. Aim: To estimate the health-related costs of tobacco from both active and passive smoking. Methods: Using local data, we estimated active and passive smoking-attributable mortality, hospital admissions, outpatient, emergency and general practitioner visits for adults and children, use of nursing homes and domestic help, time lost from work due to illness and premature mortality in the productive years. Morbidity risk data were used where possible but otherwise estimates based on mortality risks were used. Utilisation was valued at unit costs or from survey data. Work time lost was valued at the median wage and an additional costing included a value of US$1.3 million for a life lost. Results: In the Hong Kong population of 6.5 million in 1998, the annual value of direct medical costs, long term care and productivity loss was US$532 million for active smoking and US$156 million for passive smoking; passive smoking accounted for 23% of the total costs. Adding the value of attributable lives lost brought the annual cost to US$9.4 billion. Conclusion: The health costs of tobacco use are high and represent a net loss to society. Passive smoking increases these costs by at least a quarter. This quantification of the costs of tobacco provides strong motivation for legislative action on smoke-free areas in the Asia Pacific Region and elsewhere. [ABSTRACT FROM AUTHOR]

Objective: To describe the characteristics of the Chinese subjects who utilised the first telephone smoking cessation service in Hong Kong, and to evaluate its effectiveness. Methods: The Quitline provided Hong Kong residents with free telephone smoking cessation services which was publicised through a press conference, media reports, pamphlets, and posters at public and private hospitals and clinics. Callers who completed an initial interview from 13 December 2000 to 31 May 2002 were included. Smokers were interviewed using a structured record sheet and provided with stage matched counselling. A follow up interview was carried out after six months. Analysis was conducted by intention-to-treat. Results: Of the 1120 callers who completed initial assessments, 1047 were current smokers and 872 consented to follow ups. Compared to the general smoking population, the Quitline attracted more of those who were female, younger, single, unemployed, higher educated, smoking more than 20 cigarettes per day, and those with quitting experience. At six months, 12% (95% confidence interval 10% to 15%) of the participants reported that they had not smoked a cigarette for the past seven days. A stepwise logistic regression model showed that the use of nicotine replacement therapy at the present attempt to quit, having made one or more serious attempts to quit in the past, perceiving less difficulties in quitting, and smoking the first cigarette at age 15 years or above were significant predictors of quitting. Conclusion: This first Quitline in Asia appears to be acceptable to Chinese smokers, with quit rate comparable to those of better funded Quitlines in the West. A low cost Quitline is a promising model for smoking cessation services in the East. [ABSTRACT FROM AUTHOR]

Study Objective: To report the evolution in perceptions and behaviours of the general public in response to the severe acute respiratory syndrome (SARS) epidemic in Hong Kong. Design: Ten similar and sequential telephone surveys were conducted during outbreak of SARS, which are classified as belonging to the First and second phases of the epidemic. Setting: Hong Kong, China. Participants: 1397 Hong Kong residents between 18 and 60 years of age. Main outcome measures: Perceptions and behaviours to SARS and its prevention. Results: Most of the respondents believed that SARS could be transmitted via direct body contact and droplets. About half of respondents believed that SARS was curable, which increased in the initial phase and decreased in the second phase. Perceived chance of infection was low (9%) but fear of infection in public places was high (48%). Perceived efficacy of hygiene measures (wearing a mask: 82%, hand washing: 93%, and home disinfection: 75%) remained high in both phases and the perceived efficacy of avoiding crowded place, and using public transportation, etc, increased initially and decreased in the second phase. In parallel, use of the three hygiene measures increased significantly in the first phase and remained high for wearing a mask and washing hands in the second phase. Percentages of people avoiding crowded place and public transportation significantly increased initially and decreased in the second phase. Conclusion: SARS related perceptions and behaviours evolved rapidly during the epidemic and Hong Kong residents quickly adopted appropriate SARS prevention measures. Timely dissemination of information seems effective in public health crises management. [ABSTRACT FROM AUTHOR]

Reports on the appointment of people infamous for their previous service to the tobacco industry in the health sector and government agency in Hong Kong, China. Appointment of former Philip Morris consultant Sarah Liao Sau-tung as secretary for environment, transport and works; Public relations services offered to former Tobacco Institute chairwoman Brenda Chow by the medical faculty of University of Hong Kong.

The article discusses Philip Morris' introduction of a plastic outer cover to its Marlboro cigarette packs to circumvent statutory health warning in Hong Kong, China. It allows the upper section, bearing the same health warnings as those printed in the same position on the actual pack, to be removed for access to the pack and the cigarettes. The cover which features the Marlboro cowboy can be slipped over the packs that will bear Hong Kong's own set of graphic warnings.
