RESUMEN

BACKGROUND: The prevalence and correlates of hardcore smokers, who have high daily cigarette consumption, no quitting history and no intention to quit, have been studied in several western developed countries, but no previous trials of smoking cessation have tested intervention effectiveness for these smokers. The current study examined if hardcore smokers can benefit from smoking reduction intervention to achieve cessation, and explored the underlying reasons. METHODS: A posteriori analysis was conducted on data from a randomized controlled trial of smoking reduction intervention on 1,154 smokers who did not want to quit. Odds ratios of 7-day point prevalence of abstinence, smoking reduction by at least 50% and quit attempt at the 6-month follow-up comparing subgroups of smokers were analyzed. RESULTS: In hardcore smokers, the odds ratio comparing the quit rate between the intervention and control group was 4.18 (95% CI: 0.51-34.65), which was greater than non-hardcore smokers (OR = 1.58, 95% CI: 0.98-2.54). The number needed to treat for hardcore and non-hardcore smokers was 8.33 (95% CI: 5.56-16.67) and 16.67 (95% CI: 8.33-233.64), respectively. In smokers who did not have quit attempt experience and those who smoked more than 15 cigarettes daily, the odds ratio comparing intervention and control group was 3.29 (95% CI: 0.72-14.98) and 1.36 (95% CI: 0.78-2.36), respectively. CONCLUSIONS: The a posteriori analysis provided pilot results that smoking reduction intervention may be effective to help hardcore smokers to quit and reduce smoking. Having no previous quit attempt was identified as more important than having large cigarette consumption in explaining the greater effectiveness of the intervention.

RESUMEN

OBJECTIVES: To examine the factors associated with smoking cessation among adult Chinese males in rural China. METHODS: The data were collected by face-to-face interviews at the respondents' household using interviewer-administered questionnaires. RESULTS: The factors associated with quitting were being residents of Guiyang, having received junior or high school education, being unmarried, being a farmer or other job holder, smoking fewer than 20 cigarettes per day, starting smoking late, smoking for shorter duration, and having a high mean score on hedonism seeking. CONCLUSIONS: Several predictors of successful quitting were identified that could help improve smoking cessation programs in China. The findings also have implications for the need for future surveys on the quitting process among rural Chinese.

RESUMEN

BACKGROUND: Different smoking cessation programmes have been developed in the last decade but utilization by the elderly is low. We evaluated a pilot mobile smoking cessation service for the Chinese elderly in Hong Kong and identified predictors of quitting. METHODS: The Mobile Smoking Cessation Programme (MSCP) targeted elderly smokers (aged 60 or above) and provided service in a place that was convenient to the elderly. Trained counsellors provided individual counselling and 4 week's free supply of nicotine replacement therapy (NRT). Follow up was arranged at 1 month by face-to-face and at 3 and 6 months by telephone plus urinary cotinine validation. A structured record sheet was used for data collection. The service was evaluated in terms of process, outcome and cost. RESULTS: 102 governmental and non-governmental social service units and private residential homes for the elderly participated in the MSCP. We held 90 health talks with 3266 elderly (1140 smokers and 2126 non-smokers) attended. Of the 1140 smokers, 365 (32%) received intensive smoking cessation service. By intention-to-treat, the validated 7 day point prevalence quit rate was 20.3% (95% confidence interval: 16.2%-24.8%). Smoking less than 11 cigarettes per day and being adherent to NRT for 4 weeks or more were significant predictors of quitting. The average cost per contact was US$54 (smokers only); per smoker with counselling: US$168; per self-reported quitter: US$594; and per cotinine validated quitter: US$827. CONCLUSION: This mobile smoking cessation programme was acceptable to elderly Chinese smokers, with quit rate comparable to other comprehensive programmes in the West. A mobile clinic is a promising model to reach the elderly and probably other hard to reach smokers.

RESUMEN

BACKGROUND: Expatriate corporate workers stationed in remote regions of developing countries with limited health care resources are at substantial risk for a variety of infectious diseases. METHODS: A survey was carried out among expatriates working at a large power plant construction site in western Ghana in 1998 to evaluate their use of pretravel medical services, current knowledge, and behavioral practices in relation to food- and waterborne disease prevention, diarrhea, malaria, respiratory infections, alcohol use, and high-risk sexual activity. An anonymous, structured, and pretested questionnaire was used. RESULTS: The response rate was 42 of 60 (70%). Most respondents were men (39 of 42, 93%) with previous international construction experience. Adherence to food and water safety recommendations decreased with time. Expatriates (15 of 23, 65%) from developed countries reported at least one episode of diarrhea, whereas no expatriates (0 of 9) from resource-poor countries reported diarrhea (p < 0.001). Use of malaria chemoprophylaxis deteriorated with increasing duration of time on the job site. None of the expatriates (0 of 9) who had been on the site for more than a year was still taking an antimalarial compared to those who had been there for 3 months or less (13 of 16) (p < 0.01). Forty-three percent (18 of 42) of the respondents reported having had a respiratory infection in the past 3 months. Only 38% (15 of 39) received preplacement education on human immunodeficiency virus (HIV) risk. A higher proportion of those who received pretravel HIV education used condoms always (4 of 5) than those who did not receive HIV education (1 of 5). DISCUSSION: The use of health advice and preventive measures was generally low among the expatriate corporate survey respondents. Adherence to preventive measures declined with the increase in length of stay. Corporations need to develop appropriate health promotion strategies targeting their expatriates in developing countries.

RESUMEN

BACKGROUND: Although evidence has shown high prevalence rates of tobacco use in the general urban populations in China, relatively little is known in its rural population. The purposes of this study were to examine smoking patterns and sociodemographic correlates of smoking in a sample of rural Chinese male residents. METHODS: The study employed a cross-sectional, multi-stage sampling design. Residents (N = 4,414; aged 15 years and older) were recruited from four geographic regions in China. Information on participants' tobacco use (of all forms), including their daily use, and sociodemographic characteristics were collected via survey questionnaires and the resultant data were analyzed using chi-square tests and logistic regression procedures. RESULTS: The overall smoking prevalence in the study sample was 66.8% (n = 2,950). Of these, the average use of tobacco products per day was 12.70 (SD = 7.99) and over 60% reported daily smoking of more than 10 cigarettes. Geographic regions of the study areas, age of the participants, marital status, ethnicity, education, occupation, and average personal annual income were found to be significantly associated with an increased likelihood of smoking among rural Chinese male residents. CONCLUSION: There is a high smoking prevalence in the Chinese rural population and smoking behaviors are associated with important sociodemographic factors. Findings suggest the need for tobacco control and intervention policies aimed at reducing tobacco use in Chinese rural smoking populations.

RESUMEN

BACKGROUND: The Chinese National People's Congress ratified the WHO Framework Convention on Tobacco Control (FCTC) on 27 August 2005, signaling China's commitment to implement tobacco control policies and legislation consistent with the treaty. This study was designed to examine attitudes towards four WHO FCTC measures among Chinese urban residents. METHODS: In a cross-sectional design study, survey data were collected from two Chinese urban cities involving a sample of 3,003 residents aged 15 years or older. Through a face-to-face interview, respondents were asked about attitudes toward four tobacco control measures developed by the WHO FCTC. Data on the four dependent measures were analyzed using multivariate logistic regression analyses. Using descriptive statistics, potential change in smoking behavior that smokers might make in response to increasing cigarette prices is also reported. RESULTS: 81.8% of the respondents in the study sample supported banning smoking in public places, 68.8% favored increasing the cigarette tax, 85.1% supported health warnings on cigarette packages, and 85.7% favored banning tobacco advertising. The likelihood to support these measures was associated with gender, educational level, and personal income. Smokers were less likely to support these measures than non-smokers, with decreased support expressed by daily smokers compared to occasional smokers, and heavy smokers compared to light smokers. The proportion of switching to cheaper cigarette brands, decreasing smoking, and quitting smoking altogether with increased cigarette prices were 29.1%, 30.90% and 40.0% for occasional smokers, respectively; and 30.8%, 32.7% and 36.5% for daily smokers, respectively. CONCLUSION: Results from this study indicate strong public support in key WHO FCTC measures and that increases in cigarette price may reduce tobacco consumption among Chinese urban residents. Findings from this study have implications with respect to policymaking and legislation for tobacco control in China.

RESUMEN

OBJECTIVES: To describe accessibility to tuberculosis (TB) diagnosis in non-resident TB patients in Shanghai, China, and to identify factors associated with delay in diagnosis. METHODS: A face-to-face interview of 222 newly diagnosed, non-resident TB patients registered in two districts of Shanghai: Changning District and Putuo District, was conducted using a structured questionnaire. RESULTS: Among the 222 non-resident TB patients, median patient's delay was 21 days and median doctor's delay was 8 days. The duration of doctor's delay was significantly longer in Changning District than Putuo District (13 vs. 5 days, P < 0.001). One-fourth of the subjects had a patient's delay longer than 42 days and a doctor's delay longer than 15 days. Logistic regression model shows that patients at lower income level, and who did not have haemoptysis symptom were more likely to have longer patient's delay. Patients who registered in Changning were more likely to have a longer doctor's delay. The proportion of diagnosis or consideration as suspected TB for referral was significantly higher in hospitals than non-hospitals. CONCLUSION: The results of this study indicate that patient- and doctor-related factors contribute significantly to delays in the diagnosis of non-resident TB patients in Chinese cities. Non-resident's poor economic status, clinical status, complexities in referral and diagnostic procedure at different districts accounted for delayed TB care-seeking and diagnosis.

RESUMEN

BACKGROUND: Although there has been a marked increase in travel among Hong Kong residents, travel-related health risks have not been well characterized nor has their use of travel medicine services. OBJECTIVES: To assess the travel health care needs of Chinese residents in Hong Kong by examining travel health problems of returning Hong Kong residents and by understanding their use of travel health services before or after travel. METHODS: Review of available data followed by a cross-sectional telephone survey of 280 travellers and 15 service providers. A structured pre-tested questionnaire was used for data collection. Household members, who were ethnic Chinese, aged 15-64 years, able to communicate in Cantonese, and who had travelled at least once during the preceding 12 months were invited to participate. RESULTS: There was a scarcity of travel medicine services in Hong Kong. The most common destinations for travellers were countries in the Asia-Pacific region, especially mainland China (33%). Twenty percent of the respondents developed health problems during or shortly after travel. Although only 9% of respondents had received pre-travel health advice, 61% used some form of precautions. Twelve percent had lost at least a day due to travel-related health problems. The service providers agreed that there are demands for travel health services. However, half of the service providers had not been trained in travel or tropical medicine. CONCLUSIONS: This study indicates the need for specialized travel medicine services in Hong Kong to improve the health of travellers.

RESUMEN

BACKGROUND: Physicians play a crucial role in promoting smoking cessation. However, there are lack of data on Chinese doctors' knowledge, beliefs, attitudes, confidence and usual practices in relation to smoking cessation. Understanding of these indicators is important in the design of any effective intervention program targeting doctors. METHODS: To assess Chinese doctors' knowledge, beliefs, attitudes, confidence and usual practices in relation to smoking cessation, a mailed questionnaire survey was conducted among 4,000 doctors registered with the Hong Kong Medical Association (HKMA) in 2002. RESULTS: Of the 757 respondents (18.9% response rate), 78% were male, 94% were non-smokers and 50% had received no basic training on smoking cessation. More than half of the doctors did not hold adequate knowledge (53%) or favorable attitudes (55%) towards smoking cessation; 44% were less confident in their smoking cessation skills. About 77% of the doctors obtained information on their patients' smoking status and recorded it in their medical record, and 29% advised all smoking patients to quit. Doctors who gave smoking cessation advice were more likely to be aged above 50 years, with more than 30 years' practice experience, working in the private sector, non- or ex-smokers, with more positive beliefs towards smoking cessation, and with higher confidence in smoking cessation skills (p < 0.001). Different factors associated with establishing and recording smoking status, arranging follow-up sessions, acquiring more knowledge and developing a more favorable attitude and greater confidence on smoking cessation-related matters were also identified. CONCLUSION: The survey has shown that existing smoking cessation service provision in Hong Kong for patients who smoke is inadequate, and has identified a lack of smoking cessation skills among doctors. Action should be taken to train doctors in smoking cessation skills and encourage them to routinely establish the smoking status of their patients and to advise all smokers to quit smoking.

RESUMEN

The aim of this study was to investigate the attitudes of Chinese adolescents toward smoking, giving up smoking, and smoking cessation programs presently available. The study was a qualitative study carried out in 2002 by focus groups of 32 male secondary school students in Hong Kong who were either current smokers or had recently given up smoking. Subjects were students (grades 8-10) attending two full-day secondary schools in Hong Kong. Participants did not feel the need to make any serious psychological preparation for quitting. They underestimated the addictive nature of cigarette smoking and felt that they could choose to quit smoking at any time with little difficulty. Several barriers to quitting were reported, including boredom, peer influence, the urge to smoke, school work pressure, the wish to do something with their hands, difficulty in concentrating, and the ready availability of free cigarettes from peers. Those who had attempted to quit smoking (26/32) reported that peer influence and boredom were the main reasons why they started smoking and insisted that willpower and determination could have helped them in their quitting attempt. Participants were unanimous that pressure or encouragement from teachers, parents, or girlfriends did not help them to stay off cigarettes. Most (24/32) of the current smokers knew that smoking cessation services were available in Hong Kong, only 50% (12/24) of those who knew had made use of such services. None of the participants were able to identify any effective way of quitting smoking, though some suggested that the best practical measure was to avoid friends who smoked. The study suggests that attempts to persuade young people to quit smoking might benefit if they were framed to address issues such as the strong influence of their peers, the ease with which tobacco products can be obtained, the casual attitudes of young people toward smoking cessation, the perceived pros and cons of quitting, and (given that underage smoking is frowned upon by many parents and teachers) the need to respect confidentiality when offering support.

RESUMEN

PURPOSE: To assess the predictors of smoking cessation and intention to quit among the Chinese elderly smokers. DESIGN: A cross-sectional survey of elderly smokers. SETTING: Shamsuipo district, Hong Kong. SUBJECT: A total of 1,318 elderly were interviewed (response rate = 83%). MEASURES: A structured questionnaire was used for data collection. The questionnaire sought information on the subject's sociodemographic background and smoking habits. The predictors for successful quitting and intention to quit were assessed by chi-square tests and multiple logistic regression. RESULTS: Of the respondents, 20.2% were current smokers, 25.4% were ex-smokers, and 54.4% were never smokers. Of the smoker (current and ex-smokers) respondents, 55.7% (335/601) had successfully quit at the time of enumeration. The predictors of quitting were living with others, receiving assistance for mobility, being nondrinkers, smoking for shorter duration, and smoking more cigarettes per day. Having health problems in the past, smoking for shorter duration, and smoking fewer cigarettes per day were predictors of intention to quit smoking. CONCLUSION: The study identified several predictors of successful quitting that could help improve the provision of current smoking cessation services. Population-based smoking cessation programs, especially those targeted to elderly, should take these predictors into consideration in the design of interventions.

RESUMEN

This study assessed the gender and age differences in smoking cessation among the Chinese youth and identified factors associated with quitting smoking. This was a clinic based cross-sectional study with longitudinal components among 129 Chinese young smokers. All services in the clinic including one week's supply of nicotine replacement therapy (NRT) were free. We used structured questionnaires at baseline and at 1, 3 and 12 months. The analysis was by intention-to-treat basis. At 12 month follow up, the 7 day point prevalence quit rate (abstinence from tobacco smoking during the 7 days preceding the follow up) was 19% (25/129) and 36% (25/69) among all the attendees and among those who were successfully followed up, respectively. There was no significant gender or age differences in the quitting outcome but females and the older youth reported more withdrawal symptoms. Not reporting any withdrawal symptoms at 3 months follow up and adherence to use NRT for at least 4 weeks were significant predictors of quitting. A clinic-based smoking cessation service among Chinese young smokers produced an acceptable quit rate with no gender and age difference, indicating that a more general quit smoking approach could be taken for the youth.

RESUMEN

OBJECTIVE: To examine whether telephone counselling based on the stages of change component of Transtheoretical model of behaviour change together with educational materials could help non-motivated smoking parents of young children to cease. DESIGN: Randomised controlled trial. SETTING: Hong Kong Special Administrative Region, PR China. PARTICIPANTS: 952 smoker fathers and mothers of Chinese children aged 5 years. INTERVENTION: Participants were randomly allocated into two groups: the intervention group received printed self-help materials and three-session telephone-based smoking cessation counselling delivered by trained counsellors; the control group received printed self-help materials only. A structured questionnaire was used for data collection at baseline and at 1, 3 and 6 month follow up. MAIN OUTCOME MEASURES: The main outcome is 7 day point prevalence quit rate at 6 months (defined as not smoking during the 7 days preceding the 6 month follow up) determined by self reports. Other secondary outcomes were self reported 24 h point prevalence quit rate and self-reported continuous quit rate and bio-chemically validated quit rate at 6 months. RESULTS: A total of 952 smoker fathers and mothers were randomized to the intervention (n = 467) and control (n = 485) groups. Most were daily smokers (92.4%) and the mean number of cigarettes smoked per day was 14.5 (SD = 8.9). By using intention-to-treat analysis, the 7 day point prevalence quit rate at 6 month follow up was significantly greater in the intervention group (15.3%; 68/444) than the control group (7.4%; 34/459) (P < 0.001). The absolute risk reduction was 7.9% (95% confidence interval: 3.78% to 12.01%). The number needed to treat to get one additional smoker to quit was 13 (95% CI: 8-26). The crude odds ratio of quitting was 2.3(95% CI: 1.5-3.5). The adjusted odds ratio was 2.1 (95% CI: 1.4-3.4) (adjusted for age, number of years smoked, and alcohol dependency). CONCLUSION: Proactive telephone counselling is an effective aid to promote smoking cessation among parents of young children.

RESUMEN

Smoking is the greatest preventable cause of death worldwide. In recent years considerable efforts have been devoted to reducing exposure to tobacco and related products. The ultimate aim has been to persuade people to stop smoking. It is generally recognized that smoking cessation is effective in reducing the burden of disease associated with smoking. However, smoking is an addiction to nicotine and relatively few people can quit successfully without professional help. Many do not want even to try. There is evidence that a reduction in cigarette consumption could result in improved health and provide an intermediate step before complete cessation, especially for those smokers who are not ready or willing to quit. Smoking reduction intervention with counselling and/or nicotine replacement therapy (NRT) have been shown by randomised controlled trials to be effective in reducing cigarette consumption for the general smoking population. We here present the argument that there may be a case for promoting smoking reduction both as a desirable goal in itself and as a first step towards smoking cessation.

RESUMEN

BACKGROUND: The effectiveness of preventive measures in combating travel-related illnesses is well recognized. However, there is a lack of information on the economic value of any travel-associated preventive measures in the literature. OBJECTIVES: The purpose of this article is to report the values of willingness to pay (WTP) to prevent travel health problems in Hong Kong's travelers. METHODS: A cross-sectional telephone survey for a sample of Hong Kong population was conducted in 1998 using a random digit dialing technique. The sample WTP values were elicited using an open-ended question. Logistic regression was performed to identify predictors of WTP. Mean WTP was estimated using Heckman's sample selection model on log-WTP. RESULTS: Of the subjects interviewed, 77% (285/369) offered positive values of WTP to prevent travel health problems. The observable WTP (zero excluded) had a higher mean (447 Hong Kong dollars) than did the zero-inclusive data (351 Hong Kong dollars). The median values were 200 Hong Kong dollars in both cases because there were a large number of protest responses. Age, travel frequency, ability to assess travel health risk, precautionary behavior, and previous exposure to health protection materials explained one's willingness to pay a positive amount for preventing travel health problems. Age, education level, and precautionary behavior were predictors of the WTP levels. CONCLUSION: The findings of this study suggest that Chinese travelers are willing to pay for the prevention of travel-related illnesses. The predictors of WTP identified could be used to suggest policy changes. However, future studies are needed to explore further the relationship between the experience of travel illnesses, the magnitude of travel health risks, and WTP.

RESUMEN

PURPOSE: To assess the prevalence of each step in the smoking-cessation process (intention to quit, attempts to quit, and successful quitting) and to examine the factors associated with them among Chinese smokers. DESIGN: A cross-sectional survey of subjects from randomly selected households. SETTING: Four thousand one hundred forty-two households in Hong Kong. SUBJECTS: A total of 11,779 persons, aged 15 years or older, were enumerated (response rate = 74.0%). MEASURES: A validated structured questionnaire was used for data collection. The questionnaire sought information on the subject's sociodemographic background, smoking habits, and workplace attitude to smoking. The predictors for successful quitting, past quitting attempts, and intention to quit were assessed by chi2 tests and multiple logistic regression. RESULTS: Of the respondents, 14.4% were current smokers, 7.5% were ex-smokers, and 78.1% were nonsmokers. Of the daily smokers, 52% intended to quit. The factors associated with quitting were being married, being in the student/retired/others category, being older, having received higher education, not smoking to kill time, and smoking because of curiosity. Being married and not smoking to kill time were associated with past quitting attempts. Being male, married, and not smoking to kill time were associated with the intention to quit smoking. CONCLUSION: The findings of this study indicate that differing predictors may contribute to the different transitional stages of smoking cessation. Population-based smoking-cessation programs should take these predictors into consideration in the design of interventions.

RESUMEN

This study aims to examine the validity of self-reports and reliability of spousal proxy reports of smoking behavior among Chinese parents with young children. Agreement of self-reported smoking status with expired CO concentration among parents in the intake interview was significant with kappa at 0.70. Agreement of the mothers' and fathers' proxy reports on their spouses' smoking status and cigarette consumption by ICC were 1.0 and 0.58, and 0.82 and 0.33, respectively. Self-report and proxy reports of smoking status are considered valid and reliable to assess smoking behavior of parents with young children in Hong Kong.

RESUMEN

RATIONALE: There are over 300 million Chinese smokers, but use of nicotine replacement therapy (NRT) is rare. On the other hand, data on the factors associated with quitting and adherence to NRT use are scarce in the East. OBJECTIVES: To describe adherence and other predictors of quitting smoking at the 12-month follow-up amongst Chinese smokers in Hong Kong. METHODS: Chinese smokers (1186) who attended the Smoking Cessation Health Centre from August 2000 through January 2002 were studied. Trained counsellors provided individual counselling and carried out follow-up interviews. We used structured questionnaires at baseline and at 1, 3 and 12 months and an intention-to-treat approach for analysis. RESULTS: Among those who received NRT (1051/1186), the prevalence of adherence (self-reported NRT use for at least 4 weeks) was 16% (95% confidence interval 14-18%). The 7-day point prevalence quit rate at 12 months (not smoking any cigarette during the past 7 days at the 12 month follow-up) was 27% (95% CI, CI 24-29%). Stepwise logistic regression model showed that adherence to NRT use, a higher income, good perceived health and having more confidence in quitting were significant predictors of quitting. The quit rate in the adherent group (40%) was greater than that of the non-adherent group (25%) (P<0.001). Older age, male, higher education, experience of NRT use, perceiving quitting as more difficult and willingness to pay were significant predictors of adherence. CONCLUSIONS: Clinically significant smoking cessation rates can be achieved among Chinese smokers in a clinic-based smoking cessation service. The NRT adherence was low and low adherence was associated with a lower quit rate. Trials of interventions to improve adherence and increase quit rates are needed.

RESUMEN

BACKGROUND: In the West, the effectiveness of smoking cessation programmes is well established. Smoking cessation programmes in the East are rare. We evaluated a pilot smoking cessation health centre (SCHC) of the Hong Kong Council on Smoking and Health (COSH). METHODS: The clinic operated 3 days a week from 6 to 9 pm. Smokers were recruited mainly by low cost publicity. Trained counsellors provided individual counselling and a 1 week free supply of nicotine replacement therapy (NRT). The programme was evaluated in terms of process, outcome and cost. RESULTS: During August 2000 to January 2002, 2212 calls were received through the clinic hotline and 1203 smokers attended the clinic. Eight hundred and forty-one were successfully followed up at 12 months. Based on intention-to-treat analysis, the 7 day point prevalence quit rate at 12 months (not smoking any cigarette during the past 7 days at the 12 month follow-up) was 27 per cent (95 per cent confidence interval, CI 25-30 per cent). The average cost per quitter was USD 339 (USD 440 including NRT cost for a 1 week free supply). Other benefits included training of healthcare workers and medical students, organization of seminars, health talks and self-help groups, and promotion of research and training. CONCLUSION: This first evaluation of a clinic-based smoking cessation service in Asia showed that the service was acceptable to Chinese smokers. The quit rate in this pilot part-time clinic is comparable to those of full-time and better funded clinics in the West. A part-time smoking cessation clinic is a promising model for piloting smoking cessation services in the East.

RESUMEN

Sexually transmissible diseases (STDs), the most common notifiable infectious conditions, remain major threats to reproductive and public health worldwide. Travelers are particularly vulnerable to STDs, because of voluntary or involuntary sexual behavior while abroad, and are significant vectors who introduce new pathogens and resistant strains to unaffected parts of the world. This article outlines some key issues that travel medicine specialists and other clinicians should revisit when providing services to travelers. We discuss obstacles to promoting sexual health, including the diversity of the target group, unanticipated opportunities for sexual risk, ambivalent cooperation by the travel and tourism industries, poorly developed travel health sectors, illegal migration and sex tourism, and lack of research about the association between travel and STDs. We also outlined some programmatic aspects of public health that should be identified and addressed for the promotion of sexual health among travelers.
