Deconstructing subjective unmet healthcare needs: a South Korean case study with policy implications

Background

Despite widespread efforts by many countries to reduce the prevalence of unmet healthcare needs within their populations, there remains a scarcity of research systematically exploring the components of these needs.

Objectives

This study aims to deconstruct subjective unmet healthcare needs into two distinct components: the experience of subjective healthcare needs (the "Needs" component) and the experience of unmet needs contingent on those healthcare needs (the "Unmet" component).

Methods

This analysis utilizes data from 13,359 adults aged 19 or older, collected through the 2018 Korea Health Panel survey, with the aim of minimizing the influence of the coronavirus disease 19 pandemic. The two dependent variables are the experience of subjective healthcare needs and whether these needs have been met. The independent variables include 15 socio-demographic, health, and functional characteristics. The study employs both a population proportion analysis and a multivariable bivariate probit model with sample selection.

Results

In South Korea, 11.6% (CI [confidence interval] = 11.0-12.3%) of the population experienced subjective unmet healthcare needs. Upon deconstructing these, 96.7% (CI = 96.2-97.1%) of the population exhibited the Needs component, and 12.0% (CI = 11.4-12.7%) displayed the Unmet component. Each independent variable showed different associations between the two components. Furthermore, effective interventions targeting the characteristics associated with each component could reduce the proportion of the population experiencing subjective unmet healthcare needs from 11.6 to 4.0%.

Conclusion

South Korea faces a significant challenge due to the considerable prevalence of subjective unmet healthcare needs. To address this challenge effectively, the universal healthcare coverage system should adapt its approach based on the characteristics associated with both the Needs and Unmet components of subjective unmet healthcare needs. To achieve this goal, it is highly recommended that the government prioritize strengthening community-based primary healthcare, which currently suffers from insufficient resources.

Smoking Behavior and Wellness among Individuals in Substance Use Disorder Treatment

Tobacco-related morbidity and mortality disproportionately affect people with substance use disorders (SUD). Encouraging overall wellness may support tobacco use cessation. We investigated relationships between wellness (health status, physical activity, sugar-sweetened beverage (SSB) consumption), cigarette smoking, and smoking cessation among SUD treatment patients to inform clinical care. Cross-sectional surveys were conducted with 395 patients in 20 California residential SUD programs. Using multivariate regression, we examined associations between smoking status and wellness. Among smokers, we examined associations between lifetime smoking exposure, cessation behaviors and attitudes, and wellness. Compared to nonsmokers (n = 121), smokers (n = 274) reported more SSB consumption, poorer physical health, and more respiratory symptoms. Among smokers, SSB consumption and respiratory symptoms increased per ten pack-years of smoking. Smokers with respiratory symptoms reported higher motivation to quit and more use of nicotine replacement therapy (NRT). Smokers with more days of poor mental health reported lower motivation to quit. Overall, cigarette smoking was associated with other health-risk behaviors among SUD treatment patients. Respiratory symptoms may increase, and poor mental health may decrease, SUD patients' intent to quit smoking. To reduce chronic disease risk among SUD patients, treatment programs should consider promoting overall wellness concurrently with smoking cessation.

Changes in Barriers That Cause Unmet Healthcare Needs in the Life Cycle of Adulthood and Their Policy Implications: A Need-Selection Model Analysis of the Korea Health Panel Survey Data

Using 68,930 observations selected from 16,535 adults in the Korea Health Panel Survey (2014-2018), this study explored healthcare barriers that prevent people from meeting their healthcare needs most severely during adulthood, and the characteristics that are highly associated with the barrier. This study derived two outcome variables: a dichotomous outcome variable on whether an individual has experienced healthcare needs, and a quadchotomous outcome variable on how an individual's healthcare needs ended. An analysis was conducted using a multivariable panel multinomial probit model with sample selection. The results showed that the main cause of unmet healthcare needs was not financial difficulties but non-financial barriers, which were time constraints up to a certain age and the lack of caring and support after that age. People with functional limitations were at a high risk of experiencing unmet healthcare needs due to a lack of caring and support. To reduce unmet healthcare needs in South Korea, the government should focus on lowering non-financial barriers to healthcare, including time constraints and lack of caring and support. It seems urgent to strengthen the foundation of "primary care", which is exceptionally scarce now, and to expand it to "community-based integrated care" and "people-centered care".

Self-Efficacy, Social-Support, and Physical Activity Measures Among Hospital Employees: A Multisite Cross-Sectional Study

INTRODUCTION

Associations across self-efficacy, social support, and multiple measures of physical activity (PA) have not been thoroughly explored in hospital employees.

METHODS

Validated surveys assessed psychosocial factors; the IPAQ-long assessed PA, and mixed-effects analyses examined relations between psychosocial variables and PA in 920 employees from 6 Texas hospitals.

RESULTS

At P <.05, self-efficacy was significantly associated with light (β = 1.67), moderate (β = 1.63), and vigorous (β = 2.78) leisure PA; with domestic PA (β = 1.64); and with moderate commute PA (β = 0.03). At P < .05, family social-support was significantly associated with light (β = 0.94), moderate (β = 0.63), and vigorous (β = .74) leisure PA; with moderate (β = 0.46) and vigorous (β = 1.24) occupation PA; with light (β = 0.58) and moderate (β = 0.20) commute PA; and with domestic PA (β = 1.18). At P < .05, social support from friends was significantly associated with light (β = 0.74), moderate (β = 0.58), and vigorous (β = .91) leisure PA; with moderate commute (β = 0.21); and with domestic PA (β = 0.82).

CONCLUSION

Interventions must emphasize self-efficacy-building strategies and the role of family support to meaningfully impact PA behaviors in this unique population.

Prevalence of and factors related with abnormal fundoscopic findings among the elderly population in a rural community in South Korea

We aimed to report the results of fundus photography ophthalmic examinations among older adults in a rural community in South Korea. We used data from the Korean Social Life, Health, and Aging Project cohort study, which was designed to examine the entire population of individuals aged 60 years or older and their spouses living in a rural Village K of Ganghwa Island, South Korea. At baseline, a total of 860 people was targeted as the study population. From December 2011 to January 2019, five health examinations were conducted, including baseline and follow-up tests. During the fifth wave of the study, we performed fundus photography to assess eye health. Ophthalmic and physical examinations were conducted for 387 people who participated in the fifth wave by trained researchers. Systemic factors were evaluated via blood and diagnostic tests. After excluding eight people who did not undergo follow-up fundoscopy, a total of 379 participants was included for analysis. We classified the participants into two groups with either no (zero) or one or more suspicious ophthalmic diseases. The abnormalities included media opacity, suspected glaucoma, and suspicion of retinal disease as diagnosed by a trained specialist. We further categorized ophthalmic conditions as clinically insignificant, follow-up needed, semi-urgent, and urgent conditions. We included 379 participants, of which 225 (59.4%) were women. The mean age of the participants was 76.4 ± 6.2 years. Among all participants, 81% (n=307) had one or more abnormalities on fundus screening. Older age, living alone, high blood pressure, and high fasting insulin were associated with an increased risk of having ≥ one eye disease. In terms of triage, 3.7% (n= 14) of the observed conditions were urgent, and 25.9% (n= 98) were semi-urgent. Therefore, we documented fundoscopy results among the elderly population in a rural community in South Korea. Elderly people living alone were more likely to have eye disease. Policies to improve eye health are needed to prevent vision loss in this population.

Knowledge on the action to be taken and recognition of symptoms of stroke in a community: findings from the May Measurement Month 2017 blood pressure screening Programme in Malaysia

Background

Information regarding the knowledge on the action to be taken during stroke and good recognition of stroke symptoms is mandatory in helping to plan out educational strategies to deliver health education to the community.

Methods

This is a cross-sectional study of adults aged 18 and above attending a blood pressure screening program in community in conjunction with May Measurement Month 2017 in Malaysia. A structured self-administered questionnaire was given to the participants who gave verbal consent. Data analysis was done using SPSS v. 23 and multiple logistic regression was used to identify the determinants of knowledge on actions to be taken during stroke and recognition of stroke symptoms.

Results

Out of 4096 respondents, 82.9–92.1% of them able to recognise the common stroke symptoms. and 74.2% of the study respondents will go to hospital within 4.5 h of stroke onset. According to binomial logistic regression analyses, adults aged 45 years old and above (OR 1.39 95%CI 1.01–1.92), being Malay (OR 1.74, 95% CI 1.27–2.40), being non-smokers (OR = 2.491, 95% CI: 1.64–3.78), hypertensives (OR: 1.57, 95% CI: 1.02–2.42)and diabetics (OR: 2.54, 95% CI:1.38–4.69) are determinants of right actions to be taken during stroke. Meanwhile, respondents aged 45 years old and older (OR = 1.68, 95% CI: 1.39–2.03), being Malay (OR = 1.49, 95% CI: 1.24–1.79), hypertensive (OR = 1.32, 95% CI: 1.04–1.66) and those who had a previous history of stroke (OR = 2.25, 95% CI: 1.01–5.00) are determinants of good recognition of stroke symptoms.

Conclusions

The overall knowledge of stroke in our study population was good. Older age, being Malay, non-smokers, hypertensives and diabetics are determinants of right actions to be taken during stroke. Meanwhile, older age, being Malay, hypertensive and those who had a previous history of stroke are determinants of good recognition of stroke symptoms.

Exercise interventions for smoking cessation

BACKGROUND

Taking regular exercise, whether cardiovascular-type exercise or resistance exercise, may help people to give up smoking, particularly by reducing cigarette withdrawal symptoms and cravings, and by helping to manage weight gain.

OBJECTIVES

To determine the effectiveness of exercise-based interventions alone, or combined with a smoking cessation programme, for achieving long-term smoking cessation, compared with a smoking cessation intervention alone or other non-exercise intervention.

SEARCH METHODS

We searched the Cochrane Tobacco Addiction Group Specialised Register for studies, using the term 'exercise' or 'physical activity' in the title, abstract or keywords. The date of the most recent search was May 2019.

SELECTION CRITERIA

We included randomised controlled trials that compared an exercise programme alone, or an exercise programme as an adjunct to a cessation programme, with a cessation programme alone or another non-exercise control group. Trials were required to recruit smokers wishing to quit or recent quitters, to assess abstinence as an outcome and have follow-up of at least six months.

DATA COLLECTION AND ANALYSIS

We followed standard Cochrane methods. Smoking cessation was measured after at least six months, using the most rigorous definition available, on an intention-to-treat basis. We calculated risk ratios (RRs) and 95% confidence intervals (CIs) for smoking cessation for each study, where possible. We grouped eligible studies according to the type of comparison, as either smoking cessation or relapse prevention. We carried out meta-analyses where appropriate, using Mantel-Haenszel random-effects models.

MAIN RESULTS

We identified 24 eligible trials with a total of 7279 adult participants randomised. Two studies focused on relapse prevention among smokers who had recently stopped smoking, and the remaining 22 studies were concerned with smoking cessation for smokers who wished to quit. Eleven studies were with women only and one with men only. Most studies recruited fairly inactive people. Most of the trials employed supervised, group-based cardiovascular-type exercise supplemented by a home-based exercise programme and combined with a multi-session cognitive behavioural smoking cessation programme. The comparator in most cases was a multi-session cognitive behavioural smoking cessation programme alone. Overall, we judged two studies to be at low risk of bias, 11 at high risk of bias, and 11 at unclear risk of bias. Among the 21 studies analysed, we found low-certainty evidence, limited by potential publication bias and by imprecision, comparing the effect of exercise plus smoking cessation support with smoking cessation support alone on smoking cessation outcomes (RR 1.08, 95% CI 0.96 to 1.22; I² = 0%; 6607 participants). We excluded one study from this analysis as smoking abstinence rates for the study groups were not reported. There was no evidence of subgroup differences according to the type of exercise promoted; the subgroups considered were: cardiovascular-type exercise alone (17 studies), resistance training alone (one study), combined cardiovascular-type and resistance exercise (one study) and type of exercise not specified (two studies). The results were not significantly altered when we excluded trials with high risk of bias, or those with special populations, or those where smoking cessation intervention support was not matched between the intervention and control arms. Among the two relapse prevention studies, we found very low-certainty evidence, limited by risk of bias and imprecision, that adding exercise to relapse prevention did not improve long-term abstinence compared with relapse prevention alone (RR 0.98, 95% CI 0.65 to 1.47; I² = 0%; 453 participants).

AUTHORS' CONCLUSIONS

There is no evidence that adding exercise to smoking cessation support improves abstinence compared with support alone, but the evidence is insufficient to assess whether there is a modest benefit. Estimates of treatment effect were of low or very low certainty, because of concerns about bias in the trials, imprecision and publication bias. Consequently, future trials may change these conclusions.

Socioeconomic and psychosocial determinants of adherence to the Mediterranean diet in a general adult Italian population

BACKGROUND

To evaluate the adherence to Mediterranean diet (MD) and its major socioeconomic and psychosocial determinants in a large sample of the Italian population, covering three main geographical areas of the Country (Southern, Central and Northern).

METHODS

Data were obtained from the Italian Nutrition & Health Survey (INHES), including a total of 7, 430 participants (age >20) recruited from all over Italy (2010-13). Dietary information was collected by the European Food Propensity Questionnaire. Adherence to MD was assessed by using the MedDietScore based on 11 food groups. Associations were tested by multivariable logistic regression analysis (Odds ratio [OR] with 95% CI).

RESULTS

Adherence to MD was higher in Southern Italy as compared with the Northern (OR = 1.34; 95% CI 1.18-1.53), and was closely associated with adult age (OR= 2.40; 1.61-3.58 for those aged > 75 years as compared with 20-34 years) and higher educational level (OR = 1.77; 1.40-2.24 for post-secondary education as opposed to lowest educational attainment). Subjects reporting adverse life events and those with family-related stress were less likely to show an optimal adherence to MD (OR = 0.55; 0.46-0.67 and OR = 0.44; 0.28-0.69, for highest vs. lowest tertile, respectively) as compared with adequate controls. A number of eating behaviours were also inversely associated with MD, such as consuming higher amount of alcohol in the weekend than in week days.

CONCLUSIONS

Adherence to MD is strongly determined by age, geographical area and educational level. Psychosocial factors and several eating behaviours are also closely associated.

Association of the Use of a Heated Tobacco Product with Perceived Stress, Physical Activity, and Internet Use in Korean Adolescents: A 2018 National Survey

The awareness and use of the recently introduced heated product in the global tobacco market is rapidly increasing. Few studies have investigated the association of this product’s use with health-related factors. To examine the association of the heated tobacco product (HTP)’s use with perceived stress, physical activity, and internet use, we analyzed data from the Korea Youth Risk Behavior Survey using multinomial logistic regression models. The participants included 60,040 students from middle school and high school. There were significant associations between high perceived stress and cigarette use only, dual use of cigarette and e-cigarette, triple use of cigarette, e-cigarette, and HTP; a negative association between HTP’s use and perceived stress; positive association between physical activity and tobacco use; and not using the internet significantly increased the odds of use of all types of tobacco products. A smoking prevention program, tailored to meet the needs of different types of tobacco product users, is recommended. A program aimed at not only increasing awareness of perceived risk but also decreasing perceived benefits of risky behaviors, should also be considered. Further research using a longitudinal design to test the causal relationship of tobacco product use with perceived stress, physical activity, and internet use is warranted.

Trends of Adherence to the Mediterranean Dietary Pattern in Northern Italy from 2010 to 2016

Little information is available on the trends of adherence to the Mediterranean dietary pattern (MDP). This study investigates food consumption trends from 2010 to 2016 in subjects living in Northern Italy. A cross-sectional study of 8584 subjects enrolled between January 2010 and December 2016 was conducted. Socio-demographic, nutrition and lifestyle characteristics were collected. A 14-item questionnaire was used to evaluate adherence to MDP. Multivariable Poisson regression was used to evaluate the trends of and the determinants for the adherence to MDP. The overall prevalence of adherence to MDP was 14% and the trend remained constant over the six years. However, there was a marked increase in nuts consumption and a slight one in white meat consumption. Furthermore, we observed a decrease in the consumption of fruit, red meat, sweets and sugar-sweetened beverages and in the use of soffritto. Finally, higher education, being older, married, physically active, and ex-smoker was associated with greater adherence to MDP, whereas the prevalence of adherence was lower in the obese. In conclusion, the consumption of some Mediterranean and non-Mediterranean food groups changed over the six years. However, overall, the prevalence of adherence to MDP did not change. Additional strategies promoting healthy dietary habits are needed.

Glycemic Index, Glycemic Load, and Lung Cancer Risk in Non-Hispanic Whites

BACKGROUND

Postprandial glucose (PPG) and insulin responses play a role in carcinogenesis. We evaluated the association between dietary glycemic index (GI) and glycemic load (GL), markers of carbohydrate intake and PPG, and lung cancer risk in non-Hispanic whites.

METHODS

GL and GI were assessed among 1,905 newly diagnosed lung cancer cases recruited from the University of Texas MD Anderson Cancer Center (Houston, TX) and 2,413 healthy controls recruited at Kelsey-Seybold Clinics (Houston, TX). We assessed associations between quintiles of GI/GL and lung cancer risk and effect modification by various risk factors. ORs and 95% confidence intervals (CI) were estimated using multivariable logistic regression.

RESULTS

We observed a significant association between GI [5th vs. 1st quintile (Q) OR = 1.49; 95% CI, 1.21-1.83; P(trend) <0.001] and lung cancer risk and GI(ac) (5th vs. 1st Q OR = 1.48; 95% CI, 1.20-1.81; P(trend) = 0.001) and lung cancer risk. We observed a more pronounced association between GI and lung cancer risk among never smokers (5th vs. 1st Q OR = 2.25; 95% CI, 1.42-3.57), squamous cell carcinomas (SCC; 5th vs. 1st Q OR = 1.92; 95% CI, 1.30-2.83), and those with less than 12 years of education (5th vs. 1st Q OR = 1.75; 95% CI, 1.19-2.58, P(interaction) = 0.02).

CONCLUSION

This study suggests that dietary GI and other lung cancer risk factors may jointly and independently influence lung cancer etiology.

IMPACT

Understanding the role of GI in lung cancer could inform prevention strategies and elucidate biologic pathways related to lung cancer risk.

The Relationship of Stage of Change for Smoking Cessation to Stage of Change for Fruit and Vegetable Consumption and Physical Activity in a Health Plan Population

Purpose.

The purpose of this study was to examine the relationship between stage of change for smoking cessation and stage of change for (1) fruit and vegetable consumption and (2) physical activity.

Design.

The data come from a cross-sectional telephone survey administered to a stratified random sample of health plan members (n = 9675).

Setting.

This study was conducted at a mixed-model health plan with approximately 1 million adult members.

Subjects.

Respondents were adults age 18 and older, who were randomly selected from five health plan product groups: commercial fully insured, commercial self-insured, two publicly subsidized plans, and Medicare supplemental insurance. Response rates ranged from 74.7% to 90.1% across these groups.

Measures.

The assessment included demographics and stage of change for smoking cessation, physical activity, and fruit and vegetable intake. Bivariate relationships among variables were analyzed with the use of contingency tables. Ordered logistic regression was used to examine the effects of stage of change for fruit and vegetable consumption and physical activity on stage of change for smoking while controlling for other factors.

Results.

Stage of change for smoking is more clearly related to stage of change for fruit and vegetable consumption (χ2 = 161.3, p < .001; Cramer's V = .11, p < .001) than to stage of change for physical activity (χ2 = 89.7, p < .001; Cramer's V = .08, p < .001). However, stage of change for fruit and vegetable consumption and physical activity are not strong predictors of stage of change for smoking.

Conclusions.

This study indicates that stage of change for both fruit and vegetable consumption and physical activity are independent constructs from stage of change for smoking cessation.

Applying the Transtheoretical Model to Tobacco Cessation and Prevention: A Review of Literature

Objective.

To comprehensively review all published, peer-reviewed research on the Transtheoretical Model (TTM) and tobacco cessation and prevention by exploring the validity of its constructs, the evidence for use of interventions based on the TTM, the description of populations using TTM constructs, and the identification of areas for further research. The three research questions answered were: “How is the validity of the TTM as applied to tobacco supported by research?” “How does the TTM describe special populations regarding tobacco use?” “What is the nature of evidence supporting the use of stage-matched tobacco interventions?”

Data Source.

Computer Database search (PsychInfo, Medline, Current Contents, ERIC, CINAHL-Allied Health, and Pro-Quest Nursing) and manual journal search.

Inclusion/Exclusion Criteria.

All English, original, research articles on the TTM as it relates to tobacco use published in peer-reviewed journals prior to March 1, 2001, were included. Commentaries, editorials, and books were not included.

Data Extraction and Synthesis.

Articles were categorized as TTM construct validation, population descriptions using TTM constructs, or intervention evaluation using TTM constructs. Summary tables including study design, research rating, purpose, methods, findings, and implications were created. Articles were further divided into groups according to their purpose. Considering both the findings and research quality of each, the three research questions were addressed.

Results.

The 148 articles reviewed included 54 validation studies, 73 population studies, and 37 interventions (some articles fit two categories). Overall, the evidence in support of the TTM as applied to tobacco use was strong, with supportive studies being more numerous and of a better design than nonsupportive studies. Using established criteria, we rated the construct validity of the entire body of literature as good; however, notable concerns exist about the staging construct. A majority of stage-matched intervention studies provided positive results and were of a better quality than those not supportive of stage-matched interventions; thus, we rated the body of literature using stage-matched tobacco interventions as acceptable and the body of literature using non–stage-matched interventions as suggestive. Population studies indicated that TTM constructs are applicable to a wide variety of general and special populations both in and outside of the United States, although a few exceptions exist.

Conclusions.

Evidence for the validity of the TTM as it applies to tobacco use is strong and growing; however, it is not conclusive. Eight different staging mechanisms were identified, raising the question of which are most valid and reliable. Interventions tailored to a smoker's stage were successful more often than nontailored interventions in promoting forward stage movement. Stage distribution is well-documented for U.S. populations; however, more research is needed for non-U.S. populations, for special populations, and on other TTM constructs.

Cigarette smoking is associated with unhealthy patterns of food consumption, physical activity, sleep impairment, and alcohol drinking in Chinese male adults

OBJECTIVES

According to a recent national survey, tobacco use is a critical public health issue in China, with more than two-thirds of Chinese males smoking. Findings in Western populations suggest that smoking may cluster with other health-risk behaviors. To explore these relationships in Chinese male adults, we utilized baseline data from the China Seven Cities Study (CSCS).

METHODS

Male adults (n = 12,122) were included. Smoking status was defined as never smokers, ex-smokers, current smokers, and current heavy smokers. Logistic regression was employed to investigate the association of cigarette smoking and patterns of food consumption, physical activity, and alcohol drinking.

RESULTS

After controlling for age, socioeconomic status, and city residence, heavy smokers consumed significantly less vegetables, fruits, milk and other dairy products, spent significantly more time watching television, slept and exercised less, and got drunk or engaged in binge drinking more frequently compared to never, ex-, or current smokers (p < 0.05).

CONCLUSIONS

Findings suggest significant associations of heavy cigarette smoking with other health-risk behaviors in Chinese male adults, underscoring the need for tobacco control interventions for Chinese males.

Exercise interventions for smoking cessation

BACKGROUND

Taking regular exercise may help people give up smoking by moderating nicotine withdrawal and cravings, and by helping to manage weight gain.

OBJECTIVES

To determine whether exercise-based interventions alone, or combined with a smoking cessation programme, are more effective than a smoking cessation intervention alone.

SEARCH METHODS

We searched the Cochrane Tobacco Addiction Group Specialized Register in April 2014, and searched MEDLINE, EMBASE, PsycINFO, and CINAHL Plus in May 2014.

SELECTION CRITERIA

We included randomized trials which compared an exercise programme alone, or an exercise programme as an adjunct to a cessation programme, with a cessation programme (which we considered the control in this review). Studies were required to recruit smokers or recent quitters and have a follow-up of six months or more. Studies that did not meet the full inclusion criteria because they only assessed the acute effects of exercise on smoking behaviour, or because the outcome was smoking reduction, are summarised but not formally included.

DATA COLLECTION AND ANALYSIS

We extracted data on study characteristics and smoking outcomes. Because of differences between studies in the characteristics of the interventions used we summarized the results narratively, making no attempt at meta-analysis. We assessed risk of selection and attrition bias using standard methodological procedures expected by The Cochrane Collaboration.

MAIN RESULTS

We identified 20 trials with a total of 5,870 participants. The largest study was an internet trial with 2,318 participants, and eight trials had fewer than 30 people in each treatment arm. Studies varied in the timing and intensity of the smoking cessation and exercise programmes offered. Only one included study was judged to be at low risk of bias across all domains assessed. Four studies showed significantly higher abstinence rates in a physically active group versus a control group at end of treatment. One of these studies also showed a significant benefit for exercise versus control on abstinence at the three-month follow-up and a benefit for exercise of borderline significance (p = 0.05) at the 12-month follow-up. Another study reported significantly higher abstinence rates at six month follow-up for a combined exercise and smoking cessation programme compared with brief smoking cessation advice. One study showed significantly higher abstinence rates for the exercise group versus a control group at the three-month follow-up but not at the end of treatment or 12-month follow-up. The other studies showed no significant effect for exercise on abstinence.

AUTHORS' CONCLUSIONS

Only two of the 20 trials offered evidence for exercise aiding smoking cessation in the long term. All the other trials were too small to reliably exclude an effect of intervention, or included an exercise intervention which may not have been sufficiently intense to achieve the desired level of exercise. Trials are needed with larger sample sizes, sufficiently intense interventions in terms of both exercise intensity and intensity of support being provided, equal contact control conditions, and measures of exercise adherence and change in physical activity in both exercise and comparison groups.

Co-morbidity, ageing and predicted mortality in antiretroviral treated Australian men: a quantitative analysis

Background

Life expectancy has increased in HIV-positive individuals receiving combination antiretroviral therapy (cART); however, they still experience increased mortality due to ageing-associated comorbidities compared with HIV-negative individuals.

Methods

A retrospective study of 314 Queensland HIV-infected males on cART was conducted. The negative impact of ageing was assessed by estimating the probability of 5-year mortality; comparisons were made between an HIV-specific predictive tool (VACS index) and the Australian Bureau of Statistics (ABS) life-tables to examine potential differences attributed to HIV. The negative impact of ageing was also assessed by the prevalence of comorbidities. Associations between comorbidity and estimates of predicted mortality by regression analysis were assessed.

Results

The mean predicted 5-year mortality rate was 6% using the VACS index compared with 2.1% using the ABS life-table (p<0.001). The proportion of patients at predicted high risk of mortality (>9%) using the VACS index or ABS life-table were 17% and 1.8% respectively. Comorbidities were also more prevalent in this cohort compared with rates of comorbidities in age-matched Australian men from the general population. Metabolic disease (38.2%) was the most prevalent comorbidity followed by renal (33.1%) and cardiovascular disease (23.9%). Multivariate analysis demonstrated that patients with a history of cardiovascular disease had a higher predicted risk of mortality (OR=1.69;95%CI:1.17-2.45) whereas ex-smokers had a lower predicted risk of mortality (OR=0.61;95%CI:0.41-0.92).

Conclusions

Using the VACS Index there is an increased predicted risk of mortality in cART-treated HIV infected Australian men compared with age-matched men using the ABS data. This increased predicted mortality risk is associated with cardiovascular disease and the number of comorbidities per subject; which suggests that the VACS Index may discriminate between high and low predicted mortality risks in this population. However, until the VACS Index is validated in Australia this data may suggest the VACS Index overestimates predicted mortality risk in this country.

Lifestyles and risk factors associated with adherence to the Mediterranean diet: a baseline assessment of the PREDIMED trial

Background

The traditional Mediterranean dietary pattern (MedDiet) is associated with longevity and low rates of cardiovascular disease (CVD). However, there is little information on who is more likely to follow this food pattern.

Aim

To evaluate how different factors are associated with lower MedDiet adherence in older Spanish subjects.

Methods

We included 7305 participants (men aged 55–80 y, women 60–80 y) at high-risk of CVD recruited into the PREDIMED trial (ISRCTN35739639). Socioeconomic, anthropometric, lifestyle characteristics and CVD risk factors were recorded. A validated 14-item questionnaire was used to evaluate MedDiet adherence at baseline. Multivariate models were used to estimate odds ratios (OR) and 95% confidence intervals for lower adherence to the MedDiet (<9 points out of 14) and ascertain factors independently associated with it.

Results

Former smoking (OR = 0.87; 95% CI, 0.78–0.98), physical activity (OR for the 3^rd vs. the 1^sttertile: 0.69; 0.62–0.78), and higher educational level (OR for university vs. less than primary school: 0.54; 0.38–0.77) were associated with higher MedDiet adherence. Conversely, having a larger waist-to-height ratio (OR for 0.1 units, 1.35; 1.22–1.49), being diabetic (OR = 1.13; 1.03–1.24), being single (OR = 1.27; 1.01–1.61) or divorced or separated (OR = 1.44; 1.09–1.89), and current smoking (OR = 1.28; 1.11–1.47) were associated with lower adherence.

Conclusions

Participants with little education, a larger waist-to-height ratio, or diabetes and those who were less physically active, single, divorced or separated, or smokers were less likely to adhere to the MedDiet, an ideal model for food choices. Stronger efforts of health promotion are needed in these groups to foster adoption of the MedDiet.

Relationship between retinopathy severity, visual impairment and depression in persons with long-term type 1 diabetes

PURPOSE

Our aim was to investigate the proportion of individuals with depression and its association with diabetic retinopathy and visual impairment in a cohort with 25 or more years of type 1 diabetes.

METHODS

This was a cross-sectional analysis at the 25-year follow-up of the population-based cohort of the Wisconsin Epidemiologic Study of Diabetic Retinopathy. Examinations followed standardized protocols and included clinical and ophthalmic evaluations and questionnaires to assess current and past medical history, use of medications, and cigarette smoking. The Center for Epidemiologic Studies Depression Scale (CES-D) was administered to all participants. Depression was defined as use of antidepressant or CES-D score ≥16.

RESULTS

A total of 484 individuals were included in the analysis. The proportion of depression was 37.8% (95% confidence interval 33.4-42.3%). A higher proportion of individuals with depression was observed among those with more severe diabetic retinopathy and visual impairment. However these associations were not statistically significant while controlling for other factors in the multivariable analyses.

CONCLUSIONS

Diabetic retinopathy severity and visual acuity in persons with long duration of type 1 diabetes were not cross-sectionally associated with depression in this cohort.

Health behaviors among short- and long- term ex-smokers: results from the Thai National Health Examination Survey IV, 2009

BACKGROUND

Although numerous studies have shown the health behaviors of ex-smokers to be better than those in regular smokers, the differences in health behaviors among ex-smokers at varying durations of cessation have not been investigated. This study aims to examine the relationship between different durations of smoking cessation and health behaviors.

METHODS

Data on dietary intake, alcohol consumption, physical activity, and smoking behavior from the Thai National Health Examination Survey IV for subjects aged 15-98 years (n=19 371) were included in the analysis. Trends between health behaviors among regular smokers, ex-smokers with different durations of smoking (<1 year, 1-10 years, >10 years), and never smokers were tested. Logistic regression models adjusted for sex, age, and economic status were used.

RESULTS

The prevalences of regular smoking, ex-smoking, and never smoking were 22.3%, 12% , and 65.7%, respectively. A trend was found for consumption of fruit, beans and meats, dairy and soy milk, whole-grain products, nutritional supplements, and eating habits. Average daily alcohol consumption (g) was lowest among ex-smokers who had quit for>10 years ex-smokers (16.4) followed by 1-10 years ex-smokers (27.2), and <1 year ex-smokers (33.7).

CONCLUSION

A longer duration of smoking cessation correlated with better health behaviors.

Factors Associated With Exercise Participation and Attitudes to Exercise Among Pregnant Smokers

Objective: We assessed exercise levels and psychosocial aspects of exercise among pregnant smokers. Methods: A cross-sectional telephone survey of 88 pregnant smokers assessed levels of participation in exercise and psychosocial aspects of exercise; namely, self-efficacy, beliefs, perceived social support, perceived barriers, intentions and stage of change. Results: The women reported slightly higher levels of physical activity than for the general population of young women. The vast majority of women interviewed reported that exercise was important in their pregnancy, that they intended exercising regularly during pregnancy and were interested in exercise classes as an aid to smoking cessation. Fatigue was the most commonly reported barrier to physical activity during pregnancy, followed by ‘it takes too much time’, ‘uncomfortable when I exercise’ or ‘not sure what to do’. The vast majority of women expressed very little confidence and social support towards exercising. Conclusion: The results suggest that there is potential for using physical activity as an aid to smoking cessation during pregnancy. However, such interventions would need to be sufficiently intensive to address perceived barriers to exercise, lack of social support, low self-efficacy and be tailored to different stages of pregnancy.

Exercise interventions for smoking cessation

BACKGROUND

Taking regular exercise may help people give up smoking by moderating nicotine withdrawal and cravings, and by helping to manage weight gain.

OBJECTIVES

To determine whether exercise-based interventions alone, or combined with a smoking cessation programme, are more effective than a smoking cessation intervention alone.

SEARCH METHODS

In July 2011, we searched the Cochrane Tobacco Addiction Group Specialized Register for studies including the terms 'exercise' or 'physical activity'. We also searched MEDLINE, EMBASE, PsycINFO, Dissertation Abstracts and CINAHL using the terms 'exercise' or 'physical activity' and 'smoking cessation'.

SELECTION CRITERIA

We included randomized trials which compared an exercise programme alone, or an exercise programme as an adjunct to a cessation programme, with a cessation programme, recruiting smokers or recent quitters, and with a follow up of six months or more.

DATA COLLECTION AND ANALYSIS

We extracted data on study characteristics and smoking outcomes. Because of differences in studies we summarized the results narratively, making no attempt at meta-analysis.

MAIN RESULTS

We identified 15 trials, seven of which had fewer than 25 people in each treatment arm. They varied in the timing and intensity of the smoking cessation and exercise programmes. Three studies showed significantly higher abstinence rates in a physically active group versus a control group at end of treatment. One of these studies also showed a significant benefit for exercise versus control on abstinence at the three-month follow up and a benefit for exercise of borderline significance (p = 0.05) at the 12-month follow up. One study showed significantly higher abstinence rates for the exercise group versus a control group at the three-month follow up but not at the end of treatment or 12-month follow up. The other studies showed no significant effect for exercise on abstinence.

AUTHORS' CONCLUSIONS

Only one of the 15 trials offered evidence for exercise aiding smoking cessation at a 12-month follow up. All the other trials were too small to reliably exclude an effect of intervention, or included an exercise intervention which was insufficiently intense to achieve the desired level of exercise. Trials are needed with larger sample sizes, sufficiently intense interventions, equal contact control conditions, and measures of exercise adherence and change in physical activity in both exercise and comparison groups.

A Population-Based Evaluation of the Intention to Quit Smoking, Cervical Cancer Screening Behaviour, and Multiple Health Behaviours Among Female Canadian Smokers

Introduction:Proschaska's transtheoretical model (TTM) of behaviour change suggests that a population of smokers varies along many dimensions, including readiness to quit and the presence of other risk factors. This study examines whether smokers contemplating quitting are more likely to be contemplating another change (e.g., Pap testing and physical activity).Methods:The study used self-reported cross-sectional data (n= 2,873) from the Canadian Community Health Survey (CCHS) Cycle 4.1 2007/2008. The association between the smoking stage of change (SOC) and Pap testing behaviour was assessed. Control variables included sociodemographic and behavioural characteristics (e.g. doctor visits and number of cigarettes smoked). The distribution of health behaviours (e.g., dietary changes and exercise) by smoking SOC among women with recent Pap tests was also examined.Results:Female smokers contemplating or preparing to quit smoking had higher odds of having a recent Pap test, OR = 1.40, 95% CI (1.19, 1.65), and OR = 1.82, 95% CI (1.47, 2.25) respectively, compared to smokers who had no intention of quitting. This association remained statistically significant after adjusting for confounders, AOR = 1.28, 95% CI (1.08, 1.52), and AOR = 1.63, 95% CI (1.31, 2.04) respectively. Fruit and vegetable consumption, physical activity, and recent dental visit were associated with advanced smoking SOC among women with recent Pap tests (P< .05).Conclusions:Advanced smoking SOC was associated with the increased likelihood of having a recent Pap test and engaging in other healthy behaviours. These findings show that targeting several health behaviours simultaneously may be an effective health promotion strategy.

Profiles of smokers and non-smokers with type 2 diabetes: initial visit at a diabetes education centers

AIMS

This study explores differences in psychosocial, behavioral and clinical characteristics among smoking and non-smoking individuals with diabetes attending diabetes education centers (DEC).

METHODS

A questionnaire was administered to 275 individuals with type 2 diabetes attending two DECs between October 2003 and 2005. The participants' characteristics were analyzed and multivariable linear and ordinal regressions were performed to adjust for variables correlated with smoking.

RESULTS

Findings revealed that smokers, compared to non-smokers, had lower outcome expectations of the benefits of self-management, lower diastolic blood pressure, and followed their recommended diet and tested blood glucose levels less often than non-smokers. Smokers also had lower intentions to use resources outside and within the DEC.

CONCLUSIONS

Results demonstrate poorer self-care behaviors among smokers compared to non-smokers and further suggest cognitive and behavioral differences between smokers and non-smokers regarding participation and attitudes toward self-management practices. These findings identify issues that need to be addressed in diabetes self-management programs to allow for more effective interventions tailored to the healthcare needs of this specific population.

Acute effects of aerobic exercise and Hatha yoga on craving to smoke

INTRODUCTION

Recent studies have examined the effects of physical activity on craving to smoke and smoking withdrawal. The current study was designed to compare and contrast the effects of 2 different forms of physical activity on general and cue-elicited craving to smoke.

METHODS

Following 1-hr nicotine abstinence, 76 daily smokers were randomly assigned to engage in a 30-min bout of cardiovascular exercise (CE; brisk walk on a treadmill), Hatha yoga (HY), or a nonactivity control condition. Participants completed measures of craving and mood, and a smoking cue reactivity assessment, before, immediately following, and approximately 20 min after the physical activity or control conditions.

RESULTS

Compared with the control condition, participants in each of the physical activity groups reported a decrease in craving to smoke, an increase in positive affect, and a decrease in negative affect. In addition, craving in response to smoking cues was specifically reduced among those who engaged in CE, whereas those who engaged in HY reported a general decrease in cravings.

CONCLUSIONS

This study provides further support for the use of exercise bouts for attenuating cigarette cravings during temporary nicotine abstinence. Results also suggest that CE can attenuate cravings in response to smoking cues. There are several areas for further research that may improve integration of exercise within smoking cessation treatment.

Negative affect as a mediator of the relationship between vigorous-intensity exercise and smoking

The present cross-sectional study evaluated whether people who engage in vigorous-intensity exercise are better able to regulate negative affective states, thereby changing core maintenance factors of smoking. Participants were a community sample of adults (n = 270) who completed self-report measures of physical activity, cigarette smoking, anxiety sensitivity, and negative affect. Consistent with hypothesis, vigorous-intensity exercise was related to lower levels of cigarette smoking, accounting for 10% of the variance in smoking. Additionally, negative affect mediated the relationship between vigorous-intensity physical activity and cigarette smoking, accounting for about 12% of this relation. Furthermore, these relationships were stronger for individuals with high anxiety sensitivity than for those with low anxiety sensitivity; including anxiety sensitivity as a moderator of the mediated relationship increased the amount of variance accounted for by negative affect to 17%. The findings are discussed in relation to developing further scientific insight into the mechanisms and pathways relevant to understanding the association among vigorous-intensity exercise, smoking, and emotional vulnerability.

Physical activity and lung cancer among non-smokers: a pilot molecular epidemiological study within EPIC

The association between physical activity, potential intermediate biomarkers and lung cancer risk was investigated in a study of 230 cases and 648 controls nested within the European Prospective Investigation of Cancer and Nutrition. Data on white blood cell aromatic-DNA adducts by (32)P-post-labelling and glutathione (GSH) in red blood cells were available from a subset of cases and controls. Compared with the first quartile, the fourth quartile of recreational physical activity was associated with a lower lung cancer risk (odds ratio (OR) 0.56, 95% confidence interval (CI) 0.35-0.90), higher GSH levels (+1.87 micromol GSH g(-1) haemoglobin, p = 0.04) but not with the presence of high levels of adducts (OR 1.05, 95% CI 0.38-2.86). Despite being associated with recreational physical activity, in these small-scale pilot analyses GSH levels were not associated with lung cancer risk (OR 0.95, 95% CI 0.84-1.07 per unit increase in GSH levels). Household and occupational activity was not associated with lung cancer risk or biomarker levels.

Anxiety and depression symptoms in patients with diabetes

AIMS

To identify the prevalence and major determinants of anxiety and depression symptoms in patients with diabetes.

METHODS

A cross-sectional study of 2049 people with Types 1 and 2 diabetes, selected from patients experiencing three different models of care in Ireland: (i) traditional mixed care; (ii) hospital/general practitioner (GP) shared care; (iii) structured GP care. Anxiety and depression symptoms were assessed with the Hospital Anxiety and Depression Scale (HADS). Analyses were conducted primarily using logistic regression with adjustment for relevant confounders.

RESULTS

The overall response rate was 71% (n = 1456). Based on the HADS, there was evidence of high levels of anxiety and depression symptoms in patients with diabetes; 32.0% (95% confidence interval = 29.5-34.6%) exceeded the HADS cut-off score of 'mild to severe' anxiety and 22.4% (95% confidence interval = 20.2-24.7%) exceeded the HADS cut-off score of 'mild to severe' depression. Diabetes complications, smoking, uncertainty about glycaemic control and being an ex-drinker or a heavy drinker were risk factors for both higher anxiety and depression scores in multivariate analysis. Female gender and poor glycaemic control were risks factors associated only with higher anxiety scores. Higher socio-economic status and older age were protective factors for lower anxiety and depression scores. Type of diabetes, insulin use, marital status and models of care were not significant predictors of anxiety and depression scores.

CONCLUSIONS

The prevalence of anxiety and depression symptoms in patients with diabetes is considerably higher than in general population samples. These data serve as a benchmark for the prevalence of anxiety and depression symptoms in patients with diabetes.

Weight concerns and smoking in a general population: the Inter99 study

OBJECTIVE

No previous studies have explored weight concerns in relation to smoking habits, or investigated how weight concerns affect smoking cessation in a general population.

METHOD

Inter99 is a population-based lifestyle interventional study, conducted in 1999-2001 in Copenhagen, Denmark, comprising 30-60 year old men and women. All daily smokers (N=2408) were offered help to quit. The baseline investigation (N=6784) was used for analysing associations of smoking status with weight concerns (cross-sectional design). To analyse how weight concerns affected smoking cessation we included the 1387 daily smokers attending 1-year follow-up; 221 of these were verified quitters (longitudinal design).

RESULTS

Daily smoking men and women had a significantly lower body mass index than never smokers (men: 3%, women 5%) but reported to be significantly less concerned of their weight (men: OR=0.64, 95%CI=0.4-0.9), women: 0.78(0.6-1.0)). Ex-smoking normal weight women were significantly more likely to be frequently concerned of their weight than never smoking normal weight women (OR=2.06, 95CI%=1.6-2.7). Fifty-two percent of the women and 32% of the men with a previous quit attempt reported that weight gain was a reason for relapse. Neither weight concerns nor eating patterns were predictive of point abstinence at 1-year follow-up.

CONCLUSION

Smokers are believed to be very concerned of their weight but in this population-based study, daily smokers more frequently ate what they wanted, had a lower BMI and were significantly less concerned of their weight than never smokers. Weight concerns and eating patterns did not predict abstinence at 1-year follow-up. It seems that weight gain and weight concerns are independent factors.

Cardiovascular risk behavior among sedentary female smokers and smoking cessation outcomes

Background

We examined female sedentary smokers' additional cardiovascular disease (CVD) risk behaviors and their associations to smoking cessation.

Methods

This study was part of a randomized controlled trial testing the effectiveness of exercise and nicotine gum in smoking cessation. Included in the analyses were 148 participants. Dietary habits and alcohol consumption were measured as additional CVD risk behaviors. High-fat diet and heavy alcohol use were considered those risk behaviors. Nicotine dependence, length of the longest quit attempt, depressive symptoms, self-efficacy, and education were examined as other baseline variables. Abstinence from tobacco was recorded through 12 months.

Results

Diet was related to depressive symptoms at baseline. Alcohol use was related to nicotine dependence and education level. Heavy alcohol use alone and accumulation of two added risk behaviors predicted poorer smoking cessation outcome. Although diet alone was not associated with cessation outcome the high-fat diet interacted with depressive symptoms, such that the depressed women with high-fat diet were significantly more likely to relapse in their quit attempt compared to other subgroups.

Conclusion

Non-moderate alcohol use alone and accumulation of multiple CVD risk behaviors seem to be associated with lower success in smoking cessation.

Impact of race, age, income, and residence on prostate cancer knowledge, screening behavior, and health maintenance in siblings of patients with prostate cancer

OBJECTIVE

This study evaluates self-reported changes in knowledge of prostate cancer (CaP), CaP screening behavior and other health-related activities in men whose brothers have been diagnosed with prostate cancer and to characterize those demographic subgroups of siblings at particular risk of failure to change their behavior.

METHODS

112 men were surveyed to self-assess their knowledge of CaP both before and after their brother's diagnosis. In addition, siblings were questioned with regard to other health-related behaviors before and after their brother's diagnosis. Demographic characteristics including age, race, income, and area of residence were also reported. Results were analyzed to determine how a brother's diagnosis with CaP affects changes in prostate cancer knowledge, screening behavior and other health related activities in these high-risk patients.

RESULTS

The impact of a brother's diagnosis of CaP affects only 40% of siblings with regard to CaP knowledge. This knowledge appears to translate into increased screening behavior and other-health-related activity in these men. Unfortunately, more than half of men have no change in CaP knowledge and correspondingly no change in screening behavior. Siblings who are older, earn less, and live in rural areas have a lower baseline knowledge of CaP and are less likely to improve their self-assessed knowledge. On regression analysis, correlates of improvement in CaP knowledge included (1) those discussing with their primary physician (OR=6.6), (2) Caucasians (OR=2.7) and (3) non-smokers (OR=3.1). Improvements in prostate cancer knowledge were found to be predictive of subsequent participation in CaP screening and annual physical exams.

CONCLUSIONS

Increased attention should be paid to siblings of CaP patients in efforts to improve their knowledge and thereby participation in screening as these patients are at an increased risk of development of this disease. Efforts should be made to educate siblings who are older, of lower income, African American, and rural residents with regard to CaP, as these subgroups appear less likely to change their knowledge and screening behavior despite their sibling's diagnosis.

Development and preliminary evaluation of a measure of support provided to a smoker among young adults

Most studies indicate a positive association between social support and smoking cessation. However, clinic-based interventions to increase support for stopping smoking have had limited success. Prior research has emphasized the smoker's perceptions of support received for smoking cessation while less attention has focused on support persons' reports of supportive behaviors provided to a smoker. This study examined select psychometric properties of the Support Provided Measure (SPM), a self-report questionnaire designed by the investigative team to assess supportive behaviors provided to a smoker. The SPM was administered to a college sample (N=771; 67% female) of young adults, aged 18 to 24 years, who reported knowing a smoker whom they thought should quit smoking. Results indicate that, in this sample, the SPM has a two-factor structure with good internal consistency reliability (Cronbach's alpha=0.77) and appears to assess a wide range of individual differences in the provision of support. Demographic correlates associated with SPM scores are described and suggestions for future research are offered.

Exercise interventions for smoking cessation

BACKGROUND

Taking regular exercise may help people give up smoking by moderating nicotine withdrawal and cravings.

OBJECTIVES

To determine whether exercise-based interventions alone or combined with a smoking cessation programme are more effective than a smoking cessation intervention alone.

SEARCH STRATEGY

We searched the Cochrane Tobacco Addiction Group specialized register for studies including the terms 'exercise' or 'physical activity' in July 2004. In August 2004 we searched MEDLINE, EMBASE, PsycINFO, CINAHL, Dissertation Abstracts and SPORTDiscus.

SELECTION CRITERIA

We included randomized trials which compared an exercise programme alone, or an exercise programme as an adjunct to a cessation programme, with a cessation programme, recruiting smokers or recent quitters, and with a follow up of six months or more.

DATA COLLECTION AND ANALYSIS

We extracted data on study characteristics and smoking outcomes. Because of differences in studies we summarized the results narratively, making no attempt at meta-analysis.

Three studies showed significantly higher abstinence rates in a physically active group versus a control group at end of treatment. One of these studies also showed a benefit for exercise versus control on abstinence at both the three month and 12 month follow-up points. One study showed significantly higher abstinence rates for the exercise group versus a control group at the three month follow up but not at the end of treatment or at 12 month follow up. The other studies showed no significant effect for exercise on abstinence.

AUTHORS' CONCLUSIONS

Only one of the 11 trials offered evidence for exercise aiding smoking cessation. All but one of the other trials were too small to conclude that the intervention was ineffective, or included an exercise intervention which was insufficiently intense to achieve the desired level of exercise. Trials are needed with larger sample sizes, sufficiently intense exercise interventions, equal contact control conditions and measures of exercise adherence.

Addressing multiple behavioral risk factors in primary care. A synthesis of current knowledge and stakeholder dialogue sessions

BACKGROUND

Addressing behavioral risk factors in primary care has become a pressing concern due to the increasing burden of behavioral risk factors on disease, healthcare costs, and public health. Risk factors considered include smoking, risky drinking, sedentary lifestyle, and unhealthy diet-singly or in combination. The already burdened primary care system needs a practical approach to efficiently and effectively address any combination of multiple risk factors. Multiple perspectives and broad insight are urgently needed to gain a deeper understanding of the interacting scientific, systems, and policy issues associated with multiple risk factor interventions (MRFIs).

PURPOSE

This paper synthesizes findings from literature reviews, epidemiologic analyses, and structured interactive dialogue sessions, and includes a set of recommendations designed to stimulate further action.

METHODS

Several papers were produced to document current knowledge, research evidence, and salient issues related to multiple risk factor assessment and intervention. Structured interactive dialogue sessions were then conducted with clinician, health system, and health policy leaders regarding what advantage or energy would be liberated by a multiple risk factor approach (rather than separate single risk factor approaches), and how to build a policy framework or constituency for MRFIs. This information is synthesized in this paper.

RESULTS

There is a clear need to address MRFIs among multiple stakeholders, including patients, purchasers, payers, clinicians, health system leaders, and policy-level stakeholders. MRFIs need to bring with them a compelling value proposition for all stakeholders, and a vision of practical and systematic ways to make it a reality in already-pressed primary care practices. Involving stakeholders in dialogue aimed at helping them see the world through each other's eyes helps overcome discouragement and generates energy for jointly designing new approaches. Recommendations for further action include the creation of multistakeholder dialogue, creation of a policy agenda, development of a translation or integration agenda that connects researchers and practitioners in a two-way exchange, initiation of a series of demonstration projects around MRFIs, and support for research on multiple (rather than only single) risk factor interventions.

CONCLUSIONS

The need to address multiple behavioral risk factors in primary care is increasingly urgent. Whereas stakeholders by themselves may be willing to address multiple risk factors, they agree that it can only be done successfully with a collaborative approach. Findings based on evidence reviews, hypotheses generation, and stakeholder dialogue provide guidance for appropriate further action that, based on what is known already, can be initiated right away.

Meeting recommendations for multiple healthy lifestyle factors. Prevalence, clustering, and predictors among adolescent, adult, and senior health plan members

BACKGROUND

Whereas much is known about single lifestyle-related health risk factor prevalence and covariates, more research is needed to elucidate the interactions among multiple healthy lifestyle factors and variables that may predict adherence to these factors. Such data may guide both clinical and health policy decision making and person-centered approaches to population health improvement.

METHODS

We document the prevalence and cluster patterns of multiple healthy lifestyle factors among a random sample of adolescents (n =616), adults (n =585), and seniors (n =685) from a large Midwestern health plan. Modifiable, lifestyle-related health factors assessed included physical activity, nonsmoking, high-quality diet, and healthy weight for all subjects; adults and seniors were also asked about their alcohol consumption. Second, we sought to identify characteristics associated with the likelihood of meeting recommendations for healthy lifestyle factors. The healthy lifestyle factors sum score was categorized into three levels, that is, 0 to 2, 3, or 4 to 5 healthy lifestyle factors (4 for adolescents), and we used ordinal logistic regression to estimate the odds of meeting each of these criteria from several demographic characteristics and disease states.

RESULTS

Overall, only 14.5% of adolescent, adult, and senior health plan members meet recommended guidelines for four common healthy lifestyle factors. Only 10.8% of adults and 12.8% of seniors met all five behavior-related factors. For adolescents, only being nondepressed was associated with an increased likelihood to be in adherence to multiple healthy lifestyle factors (odds ratio [OR]=2.15; p <0.05). For adults, being in the 50- to 64-year-old cohort (OR=1.46, p<0.05), having a college degree (OR=1.65; p <0.05), and having no chronic disease (OR=1.92; p <0.05) were all associated with an increased likelihood to be in adherence to multiple healthy lifestyle factors. For seniors, having a college degree (OR=1.61; p <0.05), was the only variable associated with an increased likelihood to be in adherence to multiple healthy lifestyle factors.

CONCLUSIONS

A small proportion of health plan members meet multiple recommended healthy lifestyle guidelines at once. This analysis identifies population subgroups of specific interest and importance based on adherence to multiple healthy lifestyle factors, and predictors for increased likelihood to be in adherence to multiple healthy lifestyle factors. It presents a potentially useful summary measure based on person-centered measures of healthy lifestyle factors. Clinicians may derive meaningful information from analyses that address adherence to multiple healthy lifestyle factors. Health systems administrators may use this information to influence health policy and resource allocation decisions. Further studies are needed to assess the usefulness of this comprehensive lifestyle-related health measure as a metric of progress toward public health goals, or as a clinical metric that conveys information on future health status and directs interventions at the individual level.

Diabetic patients who smoke: are they different?

BACKGROUND

We wanted to identify differences between diabetic patients who smoke and those who do not smoke to design more effective strategies to improve their diabetes care and encourage smoking cessation.

METHODS

A random sample of adult health plan members with diabetes were mailed a survey questionnaire, with telephone follow-up, asking about their attitudes and behaviors regarding diabetes care and smoking. Among the 1,352 respondents (response rate 82.4%), we found 188 current smokers whose answers we compared with those of 1,264 nonsmokers, with statistical adjustment for demographic characteristics and duration of diabetes.

RESULTS

Smokers with diabetes were more likely to report fair or poor health (odds ratio [OR] = 1.5, P = .03) and often feeling depressed (OR = 1.7, P = .004). Relative to nonsmokers, smokers had lower rates of checking blood glucose levels, were less physically active, and had fewer diabetes care visits, glycated hemoglobin (A1c) tests, foot examinations, eye examinations, and dental checkups (P < or = .01). Smokers also reported receiving and desiring less support from family and friends for specific diabetic self-management activities and had lower readiness to quit smoking than has been observed in other population groups.

CONCLUSIONS

Clinicians should be aware that diabetic patients who smoke are more likely to report often feeling depressed and, even after adjusting for depression, are less likely to be active in self-care or to comply with diabetes care recommendations. Diabetic patients who smoke are special clinical challenges and are likely to require more creative and consistent clinical interventions and support.

Changing multiple health behaviors: smoking and exercise

BACKGROUND

Previous stage of change research examining health behaviors has tended to examine one behavior at a time. However, one recent study by King et al. (1996) examined the relationship between smoking and exercise across cognitive-behavioral mediators (i.e., decisional balance and self-efficacy) shown to be important in predicting readiness to change. In this study, we seek to replicate the study of King et al. (1996) in a low-income sample, the majority of whom are women, with at least one chronic illness who are attending primary care clinics.

METHODS

Data were obtained from 270 adult outpatients attending four public primary care clinics in Louisiana.

RESULTS

Smoking and exercise stage of change were not related. Significant relationships existed between the cognitive variables of smoking and exercise. No significant differences existed within exercise stage of change on the cognitive variables of smoking, and vice versa, no significant differences were noted within smoking stage of change on the cognitive variables of exercise.

CONCLUSIONS

Smoking and exercise appear to be specific health behaviors that are independent constructs in this particular sample. However, caution should be taken when interpreting the findings since 75% of the sample had at least one chronic illness.

Gender, age, socio-demographic and lifestyle factors associated with major dietary patterns in the Spanish Project SUN (Seguimiento Universidad de Navarra)

OBJECTIVE

To ascertain the major dietary patterns in the cohort 'SUN' and to assess the association of several sociodemographic (including age and gender) and lifestyle variables with the adherence to these dietary patterns.

DESIGN

This study is a cross-sectional analysis of 3847 subjects (1587 men and 2260 women) belonging to a prospective cohort study based on self-reported questionnaires. A factor analysis based on 30 predefined food groups was conducted to ascertain the major dietary patterns in the cohort. Multiple regression models were fitted to assess the relationship between several sociodemographic and lifestyle variables and the adherence to these dietary patterns (measured using two scores with observed values ranging from -3.2 to +4.6 for the Western pattern and -3.1 to +5.5 for the Mediterranean pattern).

RESULTS

Two major dietary patterns were found. The first pattern was labelled as a 'Western' dietary pattern and the other as a 'Spanish-Mediterranean' dietary pattern. Younger subjects were more likely to follow a 'Western' dietary pattern; the coefficient representing the change for every 10 y increase in age was b=-0.24 (P<0.001) for men and b=-0.12 (P<0.001) for women. More physically active subjects were less likely to follow a 'Western' dietary pattern and more likely to follow a 'Spanish-Mediterranean' dietary pattern.

CONCLUSIONS

An association between a higher level of physical activity during leisure time and adherence to a 'Spanish-Mediterranean' diet was apparent. However, the profile of being a young, sedentary and single male was identified as the most likely to exhibit a departure from the traditional 'Spanish-Mediterranean' diet and follow a 'Western' dietary pattern.

Smoking withdrawal and prolonged hospitalization

Many individuals who smoke are hospitalized for extended periods of time for treatment of their diseases. These patients are at increased risk for developing withdrawal symptoms and maladaptive behavior because hospitals have adopted smoke-free policies in accordance with federal law and consumer pressures. Tobacco addiction often is overlooked by healthcare providers or receives low priority on admission. Oncology nurses care for a chronic population of people who often require lengthy treatments and frequent complications resulting in admissions to the hospital. Nurses need to identify high-risk patients; continually educate themselves, their patients, and their patients' families about smoking withdrawal and cessation therapies; anticipate coping difficulties; and be prepared to manage inappropriate behavior when necessary.

Fruit and vegetable consumption is lower and saturated fat intake is higher among Canadians reporting smoking

Understanding differences in dietary patterns by smoking status is important for nutritionists and health educators involved in helping individuals to make healthy dietary and lifestyle choices. Although smokers have a poor quality diet compared with nonsmokers, no study has examined nutritional adequacy and variability in the nutrient intake of smokers. The aim of this study was to compare dietary habits of smokers with nonsmokers in terms of nutrient intake, food groups contributing to nutrient intake, nutritional adequacy and day-to-day variation in nutrient intake. Noninstitutionalized adults aged 18--65 y (n = 1543) who participated in the Food Habits of Canadians Survey (1997--1998) were studied. Subjects, selected from across Canada using a multistage, random-sampling strategy, completed an in-home 24-h dietary recall. Repeat interviews were conducted in a subsample to estimate variability in nutrient intake. Smokers had higher intakes of total and saturated fat, and lower intakes of folate, vitamin C and fiber than nonsmokers. There were no significant differences in calcium, zinc and vitamin A intakes or day-to-day variation in nutrient intake by smoking status. Smokers consumed significantly fewer fruits and vegetables than nonsmokers, leading to lower intakes of folate and vitamin C. In conclusion, smokers have a less healthy diet than nonsmokers, placing them at higher risk for chronic disease as a result of both dietary and smoking habits. Diet may act as a confounder in smoking-disease relationships.
