RESUMO

OBJECTIVES: To evaluate the association between healthy lifestyle behaviours and the incidence of irritable bowel syndrome (IBS). DESIGN: Population-based prospective cohort study. SETTING: The UK Biobank. PARTICIPANTS: 64 268 adults aged 37 to 73 years who had no IBS diagnosis at baseline were enrolled between 2006 and 2010 and followed up to 2022. MAIN EXPOSURE: The five healthy lifestyle behaviours studied were never smoking, optimal sleep, high level of vigorous physical activity, high dietary quality and moderate alcohol intake. MAIN OUTCOME MEASURE: The incidence of IBS. RESULTS: During a mean follow-up of 12.6 years, 961 (1.5%) incident IBS cases were recorded. Among the 64 268 participants (mean age 55.9 years, 35 342 (55.0%) female, 7604 (11.8%) reported none of the five healthy lifestyle behaviours, 20 662 (32.1%) reported 1 behaviour, 21 901 (34.1%) reported 2 behaviours and 14 101 (21.9%) reported 3 to 5 behaviours at baseline. The multivariable adjusted hazard ratios associated with having 1, 2 and 3 to 5 behaviours for IBS incidence were 0.79 (95% confidence intervals 0.65 to 0.96), 0.64 (0.53 to 0.78) and 0.58 (0.46 to 0.72), respectively (P for trend <0.001). Never smoking (0.86, 0.76 to 0.98, P=0.02), high level of vigorous physical activity (0.83, 0.73 to 0.95, P=0.006) and optimal sleep (0.73, 0.60 to 0.88, P=0.001) demonstrated significant independent inverse associations with IBS incidence. No significant interactions were observed between these associations and age, sex, employment status, geographic location, gastrointestinal infection, endometriosis, family history of IBS or lifestyle behaviours. CONCLUSIONS: Adhering to a higher number of healthy lifestyle behaviours is significantly associated with a lower incidence of IBS in the general population. Our findings suggest the potential of lifestyle modifications as a primary prevention strategy for IBS.

RESUMO

BACKGROUND: To inform the development of an intervention, it is essential to have a well-developed theoretical understanding of how an intervention causes change, as stated in the UK Medical Research Council guidelines for developing complex interventions. Theoretical foundations are often ignored in the development of mobile health apps intended to support pain self-management for patients with cancer. OBJECTIVE: This study aims to systematically set a theory- and evidence-driven design for a pain self-management app and specify the app's active features. METHODS: The Behavior Change Wheel (BCW) framework, a step-by-step theoretical approach to the development of interventions, was adopted to achieve the aim of this study. This started by understanding and identifying sources of behavior that could be targeted to support better pain management. Ultimately, the application of the BCW framework guided the identification of the active contents of the app, which were characterized using the Behavior Change Technique Taxonomy version 1. RESULTS: The theoretical analysis revealed that patients may have deficits in their capability, opportunity, and motivation that prevent them from performing pain self-management. The app needs to use education, persuasion, training, and enablement intervention functions because, based on the analysis, they were found the most likely to address the specified factors. Eighteen behavior change techniques were selected to describe precisely how the intervention functions can be presented to induce the desired change regarding the intervention context. In other words, they were selected to form the active contents of the app, potentially reducing barriers and serving to support patients in the self-management of pain while using the app. CONCLUSIONS: This study fully reports the design and development of a pain self-management app underpinned by theory and evidence and intended for patients with cancer. It provides a model example of the BCW framework application for health app development. The work presented in this study is the first systematic theory- and evidence-driven design for a pain app for patients with cancer. This systematic approach can support clarity in evaluating the intervention's underlying mechanisms and support future replication.

RESUMO

BACKGROUND: There is growing interest in the collection and use of patient-reported outcome measures (PROMs) to support clinical decision making in patients with non-small cell lung cancer (NSCLC). However, an overview of research into the prognostic value of PROMs is currently lacking. AIM: To explore to what extent, how, and how robustly the value of PROMs for prognostic prediction has been investigated in adults diagnosed with NSCLC. METHODS: We systematically searched Medline, Embase, CINAHL Plus and Scopus for English-language articles published from 2011 to 2021 that report prognostic factor study, prognostic model development or validation study. Example data charting forms from the Cochrane Prognosis Methods Group guided our data charting on study characteristics, PROMs as predictors, predicted outcomes, and statistical methods. Two reviewers independently charted the data and critically appraised studies using the QUality In Prognosis Studies (QUIPS) tool for prognostic factor studies, and the risk of bias assessment section of the Prediction model Risk Of Bias ASsessment Tool (PROBAST) for prognostic model studies. RESULTS: Our search yielded 2,769 unique titles of which we included 31 studies, reporting the results of 33 unique analyses and models. Out of the 17 PROMs used for prediction, the EORTC QLQ-C30 was most frequently used (16/33); 12/33 analyses used PROM subdomain scores instead of the overall scores. PROMs data was mostly collected at baseline (24/33) and predominantly used to predict survival (32/33) but seldom other clinical outcomes (1/33). Almost all prognostic factor studies (26/27) had moderate to high risk of bias and all four prognostic model development studies had high risk of bias. CONCLUSION: There is an emerging body of research into the value of PROMs as a prognostic factor for survival in people with NSCLC but the methodological quality of this research is poor with significant bias. This warrants more robust studies into the prognostic value of PROMs, in particular for predicting outcomes other than survival. This will enable further development of PROM-based prediction models to support clinical decision making in NSCLC.

RESUMO

BACKGROUND: There is no definitive method of accurately diagnosing appendicitis before surgery. We evaluated the feasibility of collecting breath samples in children with abdominal pain and gathered preliminary data on the accuracy of breath tests. METHODS: We conducted a prospective pilot study at a large tertiary referral paediatric hospital in the UK. We recruited 50 participants with suspected appendicitis, aged between 5 and 15 years. Five had primary diagnosis of appendicitis. The primary outcome was the number of breath samples collected. We also measured the number of samples processed within 2 h and had CO2 ≥ 3.5%. Usability was assessed by patient-reported pain pre- and post-sampling and user-reported sampling difficulty. Logistic regression analysis was used to predict appendicitis and evaluated using the area under the receiver operator characteristic curve (AUROC). RESULTS: Samples were collected from all participants. Of the 45 samples, 36 were processed within 2 h. Of the 49 samples, 19 had %CO2 ≥ 3.5%. No difference in patient-reported pain was observed (p = 0.24). Sampling difficulty was associated with patient age (p = 0.004). The logistic regression model had AUROC = 0.86. CONCLUSIONS: Breath tests are feasible and acceptable to patients presenting with abdominal pain in clinical settings. We demonstrated adequate data collection with no evidence of harm to patients. The AUROC was better than a random classifier; more specific sensors are likely to improve diagnostic performance. TRIAL REGISTRATION: ClinicalTrials.gov, NCT03248102. Registered 14 Aug 2017.

RESUMO

CONTEXT: Pain is one of the most devastating symptoms for cancer patients. One third of patients who experience pain do not receive effective treatment. A key barrier to effective pain management is lack of routine measurement and monitoring of pain. Patient-reported outcome measures (PROMs) are recommended for measuring cancer pain. However, evidence to guide the selection of the most appropriate measure to identify and monitor cancer pain is limited. A systematic review of measurement properties of PROMs for pain in cancer patients is needed to identify the best validated measure for adoption to an electronic platform. OBJECTIVES: To systematically review measurement properties of PROMs used for adult cancer patients to measure pain and, as a secondary goal, to investigate the evidence of validated mobile health (mHealth) applications used to measure pain (registration number: CRD42017065575). METHODS: Medline, Embase, and the Cumulative Index to Nursing and Allied Health Literature (CINAHL) were systematically searched in March 2018 for studies examining measurement properties for PROMs for pain in adult cancer patients. The methodological quality of the studies and their results were appraised using the Consensus-based Standards for the Selection of Health Measurement Instruments (COSMIN) checklist and specific measurement properties criteria, respectively. RESULTS: Sixteen studies evaluating 8 instruments were included. No studies using a PROM in an mHealth application were identified. The methodological quality of the measurement properties ranged between poor and fair. No instrument showed strong positive evidence for all the evaluated measurement properties. Based on the available evidence, the Brief Pain Inventory-Short Form (BPI-SF) had the strongest evidence to support its selection for the measurement of cancer pain. CONCLUSION: The BPI-SF was the best performing measure across all properties evaluated through COSMIN. Better quality validation studies of PROMs for cancer pain are needed to explore the full range of measurement properties. Utilizing mHealth applications to measure pain in cancer patients is an innovative approach worthy of further investigation.

RESUMO

Concentrations of both fine particulate matter (PM2.5) and ozone (O3) in the United States (US) have decreased significantly since 1990, mainly because of air quality regulations. Exposure to these air pollutants is associated with premature death. Here we quantify the annual mortality burdens from PM2.5 and O3 in the US from 1990 to 2010, estimate trends and inter-annual variability, and evaluate the contributions to those trends from changes in pollutant concentrations, population, and baseline mortality rates. We use a fine-resolution (36 km) self-consistent 21-year simulation of air pollutant concentrations in the US from 1990 to 2010, a health impact function, and annual county-level population and baseline mortality rate estimates. From 1990 to 2010, the modeled population-weighted annual PM2.5 decreased by 39 %, and summertime (April to September) 1 h average daily maximum O3 decreased by 9 % from 1990 to 2010. The PM2.5-related mortality burden from ischemic heart disease, chronic obstructive pulmonary disease, lung cancer, and stroke steadily decreased by 54% from 123 700 deaths year-1 (95% confidence interval, 70 800-178 100) in 1990 to 58 600 deaths year-1 (24 900-98 500) in 2010. The PM2.5-related mortality burden would have decreased by only 24% from 1990 to 2010 if the PM2.5 concentrations had stayed at the 1990 level, due to decreases in baseline mortality rates for major diseases affected by PM2.5. The mortality burden associated with O3 from chronic respiratory disease increased by 13% from 10 900 deaths year-1 (3700-17 500) in 1990 to 12 300 deaths year-1 (4100-19 800) in 2010, mainly caused by increases in the baseline mortality rates and population, despite decreases in O3 concentration. The O3-related mortality burden would have increased by 55% from 1990 to 2010 if the O3 concentrations had stayed at the 1990 level. The detrended annual O3 mortality burden has larger inter-annual variability (coefficient of variation of 12%) than the PM2.5-related burden (4%), mainly from the inter-annual variation of O3 concentration. We conclude that air quality improvements have significantly decreased the mortality burden, avoiding roughly 35 800 (38%) PM2.5-related deaths and 4600 (27%) O3-related deaths in 2010, compared to the case if air quality had stayed at 1990 levels (at 2010 baseline mortality rates and population).

RESUMO

Intracardiac leiomyomatosis is a rare complication that occurs when a uterine leiomyoma (fibroid) undergoes vascular invasion and propagates within the inferior vena cava to reach the right atrium. This article describes a case of intracardiac leiomyomatosis in a middle-aged woman, exploring the presentation, diagnosis and surgical management of this condition. In this case the presenting complaints were syncope and atrial fibrillation, illustrating the importance of performing a transthoracic echocardiogram in patients presenting with their first episode of atrial fibrillation. Clinicians should consider intracardiac leiomyomatosis when evaluating women with right heart masses, especially those with a history of uterine leiomyomas.

RESUMO

INTRODUCTION: Young smokers often report depressive symptoms while receiving smoking cessation counseling. This study examines time patterns in the quitting process among young smokers with or without notable depressive symptoms. METHODS: The quitting trajectories of young smokers aged 12 to 25 (n = 578) who called the Youth Quitline in Hong Kong between March 2006 and May 2011 were recorded and analyzed through multiple telephone sessions over periods of up to 6 months. The time patterns of young smokers who had or did not have notable depressive symptoms were compared using nonparametric Kaplan-Meier methods with log-rank tests. RESULTS: Among young smokers with low levels of nicotine dependence, those who had notable depressive symptoms were less likely to initiate a quit attempt within 28 days after their baseline telephone intervention (probability = .38 vs. .60; P value = .04). Furthermore, young smokers who had notable depressive symptoms were less likely to remain abstinent from smoking for 2 days after starting a quit attempt (probability = .50 vs. .64; P value = .012). Young adults aged 18 or above were more likely to relapse into smoking (adjusted HR = 1.50, 95% CI = 1.01, 2.22). CONCLUSIONS: Depressive symptoms may delay young smokers from initiating quit attempts and shorten their abstinence. A baseline screening process is suggested for identifying youths with co-occurring depressive disorder and nicotine dependence. Further studies should examine a collaborative model of smoking cessation that involves both counselors and physicians in preventing young smokers from rapid relapses after they make quit attempts.

RESUMO

IMPORTANCE: Intracameral injection of cefuroxime sodium (1 mg/0.1 mL) has been reported to reduce the risk of endophthalmitis following cataract surgery. In the United States it must be compounded, which is subject to dilution error. We describe a series of 13 eyes that received intracameral injection of cefuroxime sodium, 9 mg/0.1 mL, intraoperatively. OBSERVATIONS: On postoperative day 1, 6 of 13 eyes (46%; 95% CI, 19%-75%) had visual acuity of 20/70 or worse and macular edema. Spectral-domain optical coherence tomography of 2 eyes revealed central subfield thicknesses of 909 and 873 µm. On postoperative day 4, the mean (SD) central subfield thickness was 309 (78) µm in the 6 eyes with diagnosed macular edema, 279 (23) µm in the fellow eyes, and 271 (38) µm in the 7 exposed eyes without macular edema. The mean (SD) time to resolution of macular edema was 5.2 (1.3) days; the final central subfield thickness ranged from 193 to 293 µm. All eyes, except 2 with preexisting ocular comorbidity, had a best-corrected final visual acuity at 1 month of 20/30 or better. Significant corneal edema was not observed. CONCLUSIONS AND RELEVANCE: Intracameral injection of cefuroxime sodium at a dose of 9 mg/0.1 mL was associated with transient macular edema and diminished visual acuity in 6 of 13 exposed eyes (46%), resolving largely within 1 week.

RESUMO

The present trial examined the effectiveness of brief interventions for smokers who joined the Hong Kong Quit to Win Contest to quit smoking. A block randomized controlled trial allocated 1003 adult daily smokers to three groups: (i) The TEL group (n = 338) received a 5-min nurse-led telephone counselling; (ii) The SMS group (n = 335) received eight text messages through mobile phone and (iii) The CONTROL group (n = 330) did not receive the above interventions. Participants with biochemically verified abstinence at 6-month follow-up could receive cash incentive. The primary outcome was the self-reported 7-day point prevalence (PP) of tobacco abstinence at 6-month follow-up. The abstinence rate in the TEL, SMS and CONTROL group was 22.2, 20.6 and 20.3%, respectively (P for TEL versus CONTROL = 0.32; P for SMS versus CONTROL = 0.40). When abstinence at 2-, 6- and 12-month follow-up was modelled simultaneously, the TEL group had a higher abstinence than the CONTROL group (Adjusted OR = 1.38, 95% CI = 1.01-1.88, P = 0 .04). In the Quit to Win Contest, the brief telephone counselling might have increased abstinence, but the text messages had no significant effect. Further studies on intensive intervention and interactive messaging services are warranted.

RESUMO

BACKGROUND: Second-hand smoke is a severe health hazard for children. Clinical guidelines suggest that nurses advise smoking parents to quit when they accompany their sick children to paediatric settings, but the guidelines did not mention what nurses can do if the parents are not with the children. This study examines the effectiveness of a low-intensity, nurse-led health instructional initiative for non-smoking mothers, to motivate them to take action to help their husbands stop smoking. METHODS: This was a randomised controlled trial and 1,483 non-smoking women, who were living with husbands who do smoke, were recruited when they accompanied with their sick children on hospital admission in general paediatic wards/outpatient departments of four hospitals in Hong Kong. The women were randomly allocated into intervention and control groups. The former received brief health education counselling from nurses, a purpose-designed health education booklet, a "no smoking" sticker, and a telephone reminder one week later; the control group received usual care. The primary outcome was the women"s action to help their smoking husbands stop smoking at 3-, 6- and 12-month follow-ups. RESULTS: A higher proportion of women in the intervention than the control group had taken action to help their husbands stop smoking at the 3-month (76% vs. 65%, P < .001), 6-month (66% vs. 49%, P < .001) and 12-month (52% vs. 40%, P < .001) follow-ups. Women who had received the intervention, had better knowledge of the health hazards of smoking, higher intention to take action, perceived their husbands' willingness to stop/reduce smoking, had previously advised their husbands to give up smoking, were aware of their husbands' history of smoking and, were aware that their husbands had made an earlier quit attempt and intended to help them stop smoking at the follow-ups. CONCLUSIONS: A brief health education intervention by nurses in paediatric settings can be effective in motivating the mothers of sick children to take action to help their husbands quit smoking. We recommend adding the following to the clinical practice guidelines on treating tobacco use and dependence: 'Nurses should offer every non-smoking mother of a sick child brief advice to encourage their husbands to stop smoking'.

RESUMO

AIM: To examine the effectiveness of a stage-matched smoking cessation counselling intervention for smokers who had cardiac diseases. METHODS: A total of 1860 Chinese cardiac patients who smoked at least one cigarette in the past 7 days and aged 18 years or above recruited from cardiac out-patient clinics in Hong Kong hospitals were allocated randomly to an intervention group or control group. The intervention group (n = 938) received counselling matched with their stage of readiness to quit by trained counsellors at baseline, 1 week and 1 month. The control group (n = 922) received brief counselling on healthy diet at baseline. The primary outcomes were self-reported 7-day and 30-day point prevalence (PP) of tobacco abstinence at 12 months after baseline. The secondary outcome measures included biochemically validated abstinence at 12-month follow-up, self-reported 7-day and 30-day PP abstinence and reduction of cigarette consumption by 50% at 3 and 6 months. RESULTS: By intention-to-treat analysis, the intervention and control groups showed no significant difference in self-reported 7-day PP abstinence (intervention: 26.5% versus control: 25.5%; P = 0.60) and 30-day PP (intervention: 25.4% versus control: 24.2%; P = 0.55), biochemically validated abstinence (intervention: 6.6% versus control: 4.9%; P = 0.14) and overall quit attempts of least 24 hours (intervention: 40.3% versus control: 34.3%; P = 0.007) at the 12-month follow-up, adjusted for the baseline stage of readiness to quit smoking. CONCLUSIONS: An intervention, based on the Stages of Change model, to promote smoking cessation in cardiac patients in China failed to find any long-term benefit.

RESUMO

INTRODUCTION: The smoking patterns of youth remain unknown after they have received smoking cessation counseling. This study aims to examine the quitting trajectories of Chinese youth smokers after they have received quitline services and to examine factors to predict their quitting trajectories. METHODS: A total of 402 Chinese youth smokers (aged 12-25 years) called a quitline and participated in telephone follow-ups at 1 week, 1 month, and 3 and 6 months after initial telephone counseling. Finite mixture modeling was employed to examine the quitting trajectories by the SAS Proc Traj group-based modeling procedure. Hierarchical multinomial logistic regression was used to compare the baseline intention to quit smoking, prosmoking attitudes, social influences, self-efficacy to quit, smoking profile, quitting history, and demographic characteristics among the trajectory groups. RESULTS: Three distinct quitting trajectory groups were identified: quitters, reducers, and persistent smokers. Both quitters and reducers dramatically reduced the level of their cigarette consumption immediately after initial counseling. Youth smokers who were intended to quit at baseline, perceived confidence to quit, and perceived importance of quitting were more likely to have successfully quit smoking at six-month follow-up. Those who had prosmoking attitudes were less likely to quit smoking. CONCLUSION: The findings reveal the profiles of youth smokers who can quit successfully and can guide the development of better and relevant interventions based on the psychosocial characteristics of youth smokers. Short-term goals such as an abrupt quit attempt or immediately reducing cigarette consumption by half may be the key to help youth smokers quit successfully.

RESUMO

OBJECTIVES: To examine the time patterns and predictors of initiating a quit attempt and subsequent sustained abstinence among youth smokers after receiving a telephone smoking cessation intervention. METHODS: This was a longitudinal study of 408 current youth smokers aged 12-25 years who called a smoking cessation hotline in Hong Kong. Telephone surveys were conducted at baseline; 1 week; and 1, 3, and 6 months to assess smoking status and other risk factors. Nonparametric Kaplan-Meier methods and hierarchical Cox's proportional odds models were applied to explore the time patterns and predictors of the quitting process. RESULTS: Half of the youth smokers initiated a quit attempt within 1 month after receiving the baseline telephone intervention, while the likelihood of further quit attempts decreased over time. Two thirds relapsed within the first 7 days after starting a quit attempt. Intention to quit, previous quit attempts, perceived physical unfitness, and other factors could predict the initiation of a quit attempt. Sustained abstinence was facilitated by making an immediate attempt to quit, adopting self-help strategies, and a perceived improvement in physical health. CONCLUSIONS: Our findings support the "catastrophic" pathway of youth smokers initiating a quit attempt. Counselors should capture the quitting momentum and motivate youth smokers to quit immediately. Interventions should include a health assessment and discussion of smokers' physical fitness. During the first week of abstinence, intensive monitoring of withdrawal symptoms, together with booster counseling, is helpful in preventing smoking relapse and could remotivate those who fail to sustain their quit attempt.

RESUMO

BACKGROUND: Behavioral theories suggest that a past quit attempt influences psycho-social determinants to predict smokers' intention to quit, although no study has tested the hypothesis among youth smokers. METHODS: A sample of 1561 Chinese secondary students, who were current smokers, were collected in a cross-sectional school-based survey in Hong Kong. RESULTS: For the 943 students with past quit attempts, those with lower daily cigarette consumption; who perceived smoking would not elicit positive social responses from others; who had one parent/teacher who prohibited them to smoke; who were aware of the health hazards of smoking and being male smokers, were more likely to have an intention to quit smoking. For the 618 students without a past quit attempt, those who did not perceive any benefit from smoking; who had parents and teachers to prohibit them to smoke and who received social support to quit, were more likely to have an intention to quit smoking. CONCLUSION: Strengthening the prohibition of smoking and providing social support may help initiate the intention to quit among youth smokers without a past quit attempt, while de-normalizing social images of smoking, providing information about the health hazards of smoking and relieving nicotine addiction may sustain quitting intentions among youth smokers with past quit attempts.

RESUMO

INTRODUCTION: New smoke-free legislation implemented in Hong Kong on 1 January 2007, prohibited smoking in the vast majority of indoor workplaces and public places. Experiences of western countries indicated that the need for smoking cessation services would increase after enactment of the smoke-free legislation, but no systematic study of this issue has been undertaken in Southeast Asia. The present study aimed to examine the impact of smoke-free legislation in promoting smoking cessation through a local quitline. METHODS: The present study reports the results of a telephone survey using interrupted time-series analysis. We operated a toll-free smoking cessation hotline (quitline) for the general public from August 2005 to September 2007. The present study measured the percent change in the number of telephone calls received and handled before and after the smoke-free legislation. RESULTS: We evaluated the quitline for 9-month periods before (January-September 2006) and after (January-September 2007) the smoke-free legislation was implemented. The call rate in the initial period was 27.6 per month compared with 34.9 per month after enactment of the legislation, a 26% increase. Based on interrupted time-series models, the initial impact of the smoke-free legislation was to increase the number of telephone calls received and handled per week (p < .001), but the impact was temporal and deteriorated within 6 months. DISCUSSION: Implementation of the new smoke-free legislation had a short-term effect in promoting the utilization of a smoking cessation quitline in Hong Kong. A systematic and long-term tobacco control campaign should be combined with smoke-free legislation to promote and sustain smokers' interests in smoking cessation.

RESUMO

PURPOSE: Assess the effectiveness of a two-step health education program by nurses delivered through nonsmoking mothers to help fathers of sick children quit smoking. DESIGN: Randomized, controlled trial. SETTING: General pediatric wards of four major hospitals in Hong Kong. SUBJECTS: Nonsmoking mothers who had a live-in smoking spouse were recruited when they brought sick children to the hospital. A total of 752 mothers were randomized into the intervention arm and 731 into the control arm. INTERVENTION: The intervention group received standardized health advice, behavior modification booklets, and a 1-week telephone reminder. The control group received usual care. MEASUREMENTS: The main outcome measure was the quit rate (7-day point prevalence) of smoking fathers as determined by telephone follow-up with mothers at 3 and 12 months. Quit attempts and smoking reduction were secondary outcome measures. RESULTS: At 3 months, more fathers in the intervention group had quit smoking (7.4% vs. 4.8%; p = .03), reduced daily cigarette consumption by 50% or more (30.6% vs. 22.6%; p < .001), and reported quit attempts (6.5% vs. 3.6%; p = .01). The differences were not statistically significant by 12 months. CONCLUSION: A simple health education intervention provided by nurses to mothers of sick children has a short-term effect in helping smoking fathers quit, reduce consumption, and trigger quit attempts. Future studies should confirm the longer-term sustainability of the effect.

RESUMO

This study examined the outcome of a 2-hour introductory lecture on tobacco and health in improving the knowledge and attitudes of nursing students toward smoking and tobacco control. A group of 78 first-year undergraduate nursing students of a major university in Hong Kong were invited to complete a self-administered questionnaire before and after the lecture. The findings indicated a significant improvement in knowledge of and attitudes about tobacco control. The study suggests that education about smoking and tobacco control should be introduced into the nursing curriculum at an early stage so appropriate knowledge, attitudes, and skills can be subsequently strengthened to prepare students to lead an effective role in delivering tobacco control nursing interventions. Finally, a model of integrating tobacco control content in the undergraduate nursing curriculum was recommended.

RESUMO

This study describes the establishment, promotion, and preliminary findings of a peer-led smoking cessation quitline for Chinese youth smokers in Hong Kong. The Youth Quitline targeted Chinese smokers aged 12 to 25, who smoked at least one cigarette in the past 30 days and were willing to leave telephone numbers for follow up. The protocol was translated from the California Smoker's Helpline and we provided toll-free telephone counseling based on motivational intervention with multiple follow-up sessions for smokers who called the service. By intention-to-treat analysis, 55% reported at least one quit attempt, and the quit rate was 22.1% (self-reported 7-day point prevalence) or 17.5% (self-reported 30-day point prevalence). The Hong Kong Youth Quitline, along with enforcement of the antismoking legislation for both youth and adults, advocacy to de-normalize smoking in the society, and appropriate publicity, could help to promote quitting among youth smokers in Hong Kong.

RESUMO

OBJECTIVE: To evaluate the effectiveness of a community-based health education program via a mobile van to promote the awareness of breast cancer and breast self-examination (BSE) practice among women in Hong Kong. DESIGN: One group pretest/posttest design. SAMPLE AND MEASUREMENTS: Seven hundred and seventy-seven women in Hong Kong completed a self-administered questionnaire before and after a breast health education program from May 2002 to March 2003. RESULTS: About half were aware of breast health and breast diseases (53.7%) and breast screening methods (48.6%) before the intervention. It was found that women who had received instruction on BSE practice, and those who were aware of breast screening methods, breast health, and breast diseases were more likely to have had prior BSE practice. Most indicated their willingness to practice BSE regularly (93.3%) and to pass on the BSE knowledge to their relatives and friends (92%) in the posttest. CONCLUSIONS: The outreach health education program has successfully reached women living in the 18 districts in Hong Kong. It appears to be useful in raising the awareness of breast health and BSE practice among the women, but longer term follow-up is required to ascertain its sustainability.
