Effect of Obesogenic Medication on Weight- and Fitness-Change Outcomes: Evidence from the Look AHEAD Study.

This study evaluates whether obesogenic medications may decrease the effectiveness of lifestyle interventions. The authors of this study hypothesized that participants who took obesogenic medications would be less responsive to the intervention in the Look AHEAD trial. In the trial, 5,145 participants with overweight or obesity, aged 45 to 76 years with type 2 diabetes, were randomly assigned to an intervention (vs. support and education). In this analysis, the association of exposure to obesogenic medications and successful weight loss (≥5% and ≥10% of total weight) and fitness gain (≥1 and ≥2 metabolic equivalents) was examined. For each outcome, multiple logistic regression models were fitted. Analytic sample sizes were 4,496 for weight-change analyses and 4,051 for fitness-change analyses. After adjusting for covariates, exposure to one or more obesogenic medications significantly decreased the odds of achieving ≥5% weight loss by 32% (odds ratio [OR] 0.68) and achieving ≥10% weight loss by 19% (OR 0.81). The association was dose-dependent-participants using two or more medications were less likely to achieve weight loss than those using one medication. Obesogenic medication exposure was not associated with decreased odds of achieving fitness gain overall. The results suggest that exposure to obesogenic medications could hinder successful weight loss in a lifestyle intervention for people with diabetes.

Creating an appropriate adaptation of a healthy lifestyle intervention for people after stroke

ABSTRACT Primary Objective To describe (1) an evidence-based approach to promoting a healthy lifestyle, the Diabetes Prevention Program Group Lifestyle Balance intervention, and (2) our work with input from an Advisory Board of stakeholders to modify the program to meet the unique needs of people post stroke. Research Design Community-Based Participatory Research Methods and Procedures An Advisory Board of stakeholders was convened to modify the Group Lifestyle Balance intervention to meet the unique needs of people post stroke. Main Outcomes and Results The primary adaptations that emerged from the Advisory Board included (1) curriculum emphasis on heart health after stroke, (2) care partner participation, (3) physical activity, dietary, and weight loss modifications specific to people after stroke, and (4) general programmatic recommendations (e.g., wider age range of participants; eligibility based on time since stroke; alternative modes of delivery). Conclusions Feedback from the diverse group of stakeholders provides the basis for modifying an evidence-based healthy lifestyle intervention to meet the unique needs of people after stroke. Future research efforts should examine the efficacy and effectiveness of the adapted program to prevent weight gain after stroke and reduce the risk of chronic conditions including diabetes, metabolic syndrome, and heart disease.

“Waiting in the Wings”—Next-of-Kin’s Experiences of Lifestyle Interventions for People with Schizophrenia

People with schizophrenia have an increased risk of experiencing physical ill health and thus risk premature death. It is important to gain knowledge about the next-of-kin’s experiences of lifestyle interventions in order to increase the understanding of the development of health promotion. This study aimed to describe the experiences of next-of-kin of lifestyle interventions for people with schizophrenia. Ten next-of-kin to people diagnosed with schizophrenia were interviewed and content analysis was used to analyze the data. Three categories emerged in the analysis: Low prioritization of physical health, Patients’ needs for motivational support and Next-of-kin’s’ limited and distant participation. Mental health nurses need a holistic view of human beings and to include the patients’ physical health and the role of the family in their responsibilities. Further studies are needed that focus on the views of the next-of-kin and the staff from the mental health services about the care and support needs for promoting physical health in this patient group.

The cost-effectiveness of pharmacotherapy and lifestyle intervention in the treatment of obesity.

SummaryBackgroundThe Food and Drug Administration has approved several pharmacotherapies for the treatment of obesity. This study assesses the cost‐effectiveness of six pharmacotherapies and lifestyle intervention for people with mild obesity (body mass indices [BMIs] 30 to 35).MethodsA microsimulation model was constructed to compare seven weight loss strategies plus no treatment: intensive lifestyle intervention, orlistat, phentermine, phentermine/topiramate, lorcaserin, liraglutide, and semaglutide. Weight loss, quality‐of‐life scores, and costs were estimated using clinical trials and other published literature. Endpoints included costs, quality‐adjusted life years (QALYs), and incremental cost‐effectiveness ratios (ICERs) with a willingness‐to‐pay (WTP) threshold of $100 000/QALY. Results were analysed at 1‐, 3‐, and 5‐year time horizons.ResultsAt each of the three follow‐up periods, phentermine was the cost‐effective strategy, with ICERs of $46 258/QALY, $20 157/QALY, and $17 880/QALY after 1, 3, and 5 years, respectively. Semaglutide was the most effective strategy in the 3‐ and 5‐year time horizons, with total QALYs of 2.224 and 3.711, respectively. However, the ICERs were prohibitively high at $1 437 340/QALY after 3 years and $576 931/QALY after 5 years. Deterministic and probabilistic sensitivity analyses indicated these results were robust.ConclusionsPhentermine is the cost‐effective pharmacologic weight‐loss strategy. Although semaglutide is the most effective, it is not cost‐effective because of its high price.

Comparative efficacy of lifestyle intervention strategies targeting weight outcomes in people with psychosis: a systematic review and network meta-analysis.

The objective of this review was to pool and rank the efficacy of lifestyle intervention strategies targeting weight, body mass index, waist circumference and waist-to-hip ratio in people with psychosis by comparing the effect size of these weight outcomes. Secondary to this, the objective was to stratify the lifestyle interventions according to their inclusion of dietary information that adheres to Australian Dietary Guidelines. People living with psychosis have a significantly increased risk of all-cause mortality, with cardiovascular disease a considerable contributor to this risk. Controlling lifestyle risk factors, which include smoking, poor diet and inadequate physical activity, leads to significant weight reduction and decreases cardiovascular disease risk. Previous reviews on this topic have not clearly identified essential components of lifestyle interventions in people with psychosis, mainly due to statistical limitations of analyses. This review employed a network meta-analysis, which compares more than two groups of interventions and ranks them according to efficacy, thus providing a global estimate of effect. Additionally, available reviews have not assessed compliance of dietary information offered in lifestyle interventions to established guidelines. This review considered randomized controlled trials that delivered lifestyle interventions to community-dwelling adults with psychotic disorders. Outcomes of interest included weight, body mass index, waist circumference and waist-to-hip ratio. The Cochrane Library, MEDLINE/PreMEDLINE, Embase, CINAHL, Scopus and PsycINFO were searched for studies published in English from 1985 to June 2018. Data were qualitatively summarized, during which lifestyle intervention subgroups were created (based on key similarities) and then compared in direct meta-analyses and network meta-analyses. Assessment of study adherence to Australian Dietary Guidelines was conducted in a narrative format. Thirty-two randomized controlled trials were included, and the overall quality of these studies ranged from what appeared to be low to moderate. Lifestyle intervention studies contained both a dietary and physical activity component, with the exception of two studies that focused solely on physical activity. Delivery of dietary and physical activity information was mainly through education; however, some studies provided additional structure to the intervention by offering tailored advice or helping participants to set goals, and providing regular review of progress for diet, physical activity or both. Results from network-meta-analyses showed that only studies with a structured approach for both diet and physical activity demonstrated significant decreases in weight (effect size = -4.12, 95% confidence interval = -7.772 to -2.760, P = 0.000) and body mass index (effect size = -2.94, 95% confidence interval = -1.78 to -0.357, P = 0.003). Waist circumference subgroup comparisons mainly comprised single studies; therefore, findings were inconclusive. Dietary information provided in studies generally complied with Australian Dietary Guidelines; however, none of the studies complied with all guidelines. Lifestyle interventions incorporating both dietary and physical activity components led to the greatest decreases in weight (4.1 kg) and body mass index (2.9 points) among people with psychosis. Important intervention strategies for both components are the personalization of education through tailored advice or goal setting, and a corresponding progress review. Dietary information in the included studies appeared to comply with the Australian Dietary Guidelines. However, these findings were weakened by an increased risk of bias, complex and multicomponent study designs, and lack of clarity in reporting of study methodology.

Morbidity and mortality after lifestyle intervention for people with impaired glucose tolerance: 30-year results of the Da Qing Diabetes Prevention Outcome Study

Lifestyle interventions can delay the onset of type 2 diabetes in people with impaired glucose tolerance, but whether this leads subsequently to fewer complications or to increased longevity is uncertain. We aimed to assess the long-term effects of lifestyle interventions in people with impaired glucose tolerance on the incidence of diabetes, its complications, and mortality. The original study was a cluster randomised trial, started in 1986, in which 33 clinics in Da Qing, China, were randomly assigned to either be a control clinic or provide one of three interventions (diet, exercise, or diet plus exercise) for 6 years for 577 adults with impaired glucose tolerance who usually receive their medical care from the clinics. Subsequently, participants were followed for up to 30 years to assess the effects of intervention on the incidence of diabetes, cardiovascular disease events, composite microvascular complications, cardiovascular disease death, all-cause mortality, and life expectancy. Of the 577 participants, 438 were assigned to an intervention group and 138 to the control group (one refused baseline examination). After 30 years of follow-up, 540 (94%) of 576 participants were assessed for outcomes (135 in the control group, 405 in the intervention group). During the 30-year follow-up, compared with control, the combined intervention group had a median delay in diabetes onset of 3·96 years (95% CI 1·25 to 6·67; p=0·0042), fewer cardiovascular disease events (hazard ratio 0·74, 95% CI 0·59-0·92; p=0·0060), a lower incidence of microvascular complications (0·65, 0·45-0·95; p=0·025), fewer cardiovascular disease deaths (0·67, 0·48-0·94; p=0·022), fewer all-cause deaths (0·74, 0·61-0·89; p=0·0015), and an average increase in life expectancy of 1·44 years (95% CI 0·20-2·68; p=0·023). Lifestyle intervention in people with impaired glucose tolerance delayed the onset of type 2 diabetes and reduced the incidence of cardiovascular events, microvascular complications, and cardiovascular and all-cause mortality, and increased life expectancy. These findings provide strong justification to continue to implement and expand the use of such interventions to curb the global epidemic of type 2 diabetes and its consequences.

Early Lifestyle Interventions in People with Impaired Glucose Tolerance in Northern Colombia: The DEMOJUAN Project.

Background: The objective of the demonstration project for type 2 diabetes prevention in the Barranquilla and Juan Mina (DEMOJUAN) study was to investigate the extent to which it is possible to reach normal glucose metabolism with early lifestyle interventions in people at high risk of type 2 diabetes (prediabetes), compared with those who receive standard usual care. Methods: DEMOJUAN was a randomized controlled trial conducted in Juan Mina and Barranquilla, Northern Colombia. Eligible participants were randomized into one of three groups (control group, initial nutritional intervention, and initial physical activity intervention). The duration of the intervention was 24 months. The main study outcome in the present analysis was reversion to normoglycemia. Relative risks and their corresponding 95% confidence intervals were calculated for reversal to normoglycemia and T2D incidence. Results: There was no statistically significant association between the intervention groups and reversion to normoglycemia. The relative risk of reversion to normoglycemia was 0.88 (95% CI 0.70–1.12) for the initial nutritional intervention group participants and 0.95 (95% CI 0.75–1.20) for the initial physical activity intervention group participants. Conclusions: Our study did not find any statistically significant differences in reversion to normoglycemia or the development of type 2 diabetes between the intervention groups and the control group in this population.

A qualitative exploration of barriers and enablers of healthy lifestyle engagement for older Australians with intellectual disabilities

Older Australians with intellectual disabilities experience high rates of lifestyle-related illness, yet generally have poor diets and participate in limited physical activity. Eliciting the perspectives of people with intellectual disabilities and support workers may inform interventions to support healthy lifestyles. A semi-structured focus group question framework was developed to investigate participants’ experiences of barriers and enablers of physical activity and healthy eating. Data from focus groups with paid support workers (n = 6) and people with intellectual disabilities (n = 8) aged 60 + years were analysed within this framework. Similarities and differences between perspectives were explored. Both groups perceived decreased physical activity as an inevitable aspect of ageing. Health problems and environmental constraints were also identified. Embedding physical activity into daily routines, providing choices, and viewing exercise as beneficial, were highlighted as enablers across groups. Support workers, but not people with intellectual disabilities, identified barriers to healthy eating including use of “junk” food to manage behaviour and lack of message consistency between care providers. Financial and human resource barriers were also highlighted by support workers. Both carers and people with intellectual disabilities may benefit from specialised support to adapt healthy lifestyle interventions for people as they age. Behavioural management strategies unrelated to food should be promoted. Organisational and policy-level commitment are needed to ensure that healthy lifestyle programs are adequately resourced to meet the needs of the ageing population with intellectual disabilities.

Reducing Morbidity and Mortality in Type 2 Diabetes by Lifestyle Intervention: 30-Year Follow-Up of the Da Qing Diabetes Prevention Study

Background Lifestyle interventions delay the onset of type 2 diabetes in people with impaired glucose tolerance (IGT), but whether this leads subsequently to fewer complications or increases longevity is uncertain. We aimed to determine the long-term effects of lifestyle intervention in people with IGT on the incidence of diabetes, its complications, and mortality. Methods In 1986, 577 adults with IGT in Da Qing, China were randomly assigned by clinic to a control group or one of three interventions (diet, exercise, or diet plus exercise) for six years. Participants were then followed for 30 years to assess the effects of intervention on the incidence of diabetes, cardiovascular events, composite microvascular complications, cardiovascular death, and life expectancy. Findings During the 30-year follow-up, the intervention group, compared with controls, had a median delay of 3·96 years (95% CI, 1·25 to 6·67; P=0·0042) in diabetes-onset with 26% fewer cardiovascular events (hazard ratio, 0·74; 95% CI, 0·59 to 0·92; P=0·0060), 28% lower incidence of severe microvascular complications (hazard ratio, 0·72; 95% CI, 0·52 to 0·99; P=0·044), 33% fewer cardiovascular disease deaths (hazard ratio, 0·67; 95% CI ,0·48 to 0·94; P=0·022), and 26% fewer total deaths (hazard ratio, 0·74; 95% CI, 0·61 to 0·89; P=0·0015), and an average increase of 1·44 life years (95% CI, 0·20 to 2·68; P=0·023). Interpretation Lifestyle intervention in people with IGT delayed the onset of type 2 diabetes, reduced the incidence of cardiovascular events, microvascular complications, cardiovascular and all-cause mortality, and increased life expectancy. The study provides strong justification to continue to implement and expand use of such interventions to curb the global diabetes epidemic and its consequences.

Response bias to a randomised controlled trial of a lifestyle intervention in people at high risk of cardiovascular disease: a cross-sectional analysis

BackgroundResearch evaluating lifestyle interventions for prevention of cardiovascular disease (CVD) may not reach those most at risk. We compared the response rate to a randomised controlled trial (RCT) of a lifestyle intervention by CVD risk, ethnicity and level of deprivation.MethodsPrimary care patients with a QRisk2 score ≥ 20% were invited to participate in a RCT of an intensive lifestyle intervention versus usual care. This cross-sectional analysis compares anonymised data of responders and non-responders with multiple logistic regression, using adjusted odds ratios (AORs) for QRisk2 score, ethnicity, Index of Multiple Deprivation (IMD 2010) quintile, age and sex.ResultsFrom 60 general practices, 8902 patients were invited and 1489 responded. The mean age was 67.3 years and 21.0% were female. Of all patients invited, 69.9% were of white ethnic background, 13.9% ethnic minority backgrounds and 16.2% had no ethnicity data recorded in their medical records. Likelihood of response decreased as QRisk2 score increased (AOR 0.82 per 5 percentage points, 95% CI 0.77–0.88). Black African or Caribbean patients (AOR 0.67; 95% CI 0.45–0.98) and those with missing ethnicity data (AOR 0.55; 95% CI 0.46–0.66) were less likely to respond compared to participants of white ethnicity, but there was no difference in the response rates between south Asian and white ethnicity (AOR 1.08; 95% CI 0.84–1.38). Patients residing in the fourth (AOR 0.70; 95% CI 0.56–0.87) and fifth (AOR 0.52; 95% CI 0.40–0.68) most deprived IMD quintile were less likely to respond compared to the least deprived quintile.ConclusionsEvaluations of interventions intended for those at high risk of CVD may fail to reach those at highest risk. Hard to reach patient groups may require different recruitment strategies to maximise participation in future trials. Improvements in primary care ethnicity data recording is required to aid understanding of how successfully study samples represent the target population.Trial registrationISRCTN, ISRCTN84864870.

The Association between Eating Traits and Weight Change after a Lifestyle Intervention in People with Type 2 Diabetes Mellitus.

Aims To date, studies on the role of eating traits in weight loss success have only included obese people without type 2 diabetes mellitus (T2DM), thereby disregarding negative effects of T2DM-related metabolic changes. Our aim was to assess the association between eating traits and weight change after a lifestyle intervention in people with T2DM. Methods For the current study, we reexamined data from a six-month intervention in 120 participants. We determined eating traits at baseline, using the DEBQ, which were used to produce three groups: unsuccessful dietary restrained (high restraint, high emotional/external eating scores), successful dietary restrained (high restraint, low emotional/external eating scores), and reference (low restraint, high or low emotional/external eating scores). Linear regression was used to study the association between the eating trait groups and weight changes after six months, while correcting for possible confounders. Results On average, the weight loss success was limited, with a third of the participants being weight stable, a third losing weight > −1 kg (average loss −2.6 ± 1.9 kg), and a third gaining weight > +1 kg (average gain +3.3 ± 1.9 kg). When compared to the reference group, the unsuccessful dietary restrained gained weight during the intervention (beta = 1.2 kg, confidence interval (CI)% = 0.1; 2). No significant change was observed in the succesful dietary restrained group. Conclusions The eating trait of being unsuccessfully dietary restrained is associated with weight-loss failure after a six-month lifestyle intervention in people with T2DM.

Lifestyle Interventions for People with, and at Risk of Type 2 Diabetes in Polynesian Communities: A Systematic Review and Meta-Analysis.

There is evidence that lifestyle intervention among Polynesian people can reduce diabetes incidence and complications, but this evidence has not been systematically reviewed. The aim of this study was to systematically review the efficacy of lifestyle interventions, targeting the prevention and management of type 2 diabetes among Polynesian people. MEDLINE, Web of Science, Cochrane Library, and Embase were searched to find randomised controlled trials (RCTs) and pre-post studies. Eight studies (four RCTs and four pre-post studies) with 1590 participants met the inclusion criteria. The data on health outcomes that was reported in these studies included blood pressure, body mass index, waist circumference, weight, and glycated haemoglobin (HbA1c). The meta-analyses showed that the interventions had resulted in statistically significant reductions in systolic blood pressure (SBP) across four of the studies (WMD, −9.93 mmHg; 95% Cl, −10.77 to −9.09; and p < 0.00001). However, the effects on weight across five of the studies (WMD, −1.15 kg; 95% Cl, −2.80 to 0.51; p = 0.18) and the HbA1c levels across two of the studies (WMD, −0.38%; 95% Cl, −1.15 to 0.39; and p = 0.33) were not statistically significant. This review provides evidence that lifestyle interventions may be effective in achieving modest reductions in SBP in Polynesian people. Further research is needed to fully assess the effectiveness of these interventions in this population long-term.

Psychiatry heal thyself: a lifestyle intervention targeting mental health staff to enhance uptake of lifestyle interventions for people prescribed antipsychotic medication

IntroductionPeople experiencing severe mental illness (SMI) face a shortened life expectancy of up to 20 years, primarily due to preventable cardiovascular (CV) diseases. Lifestyle interventions are effective in reducing CV risk, yet examples of service-wide interventions are lacking. Staff culture remains a barrier to the successful implementation of lifestyle interventions. The Keeping the Body in Mind (KBIM) program, established by SESLHD (Australia), aims to close the gap in life expectancy through multidisciplinary teams, including clinical nurse consultants, dieticians, exercise physiologists, and peer support workers. Prior to the KBIM rollout, an individualized lifestyle intervention called Keeping Our Staff In Mind (KoSiM) was offered to all district mental health staff.ObjectiveKoSiM examined the effectiveness of a staff intervention to improve physical health, confidence, knowledge and attitudes of mental health staff.MethodsMental health staffs were invited to participate in an online survey and a 4-week individualized intervention including personalised health screening and lifestyle advice, with a 16-week follow-up. Outcomes assessed included: attitudes, confidence and knowledge regarding metabolic health, weight, waist circumference (WC), blood pressure, sleep, diet, physical activity and exercise capacity.ResultsOf a total of 702 staff, 204 completed the survey (29%). Among those completing the survey, 154 staff (75%) participated in the intervention. A mean decrease in waist circumference of 2 ± 2.7 cm, (P &lt; 0.001) was achieved. Among staffs that were overweight or obese at baseline, 75% achieved a decrease in WC.ConclusionImproving staff culture regarding physical health interventions is an important step in integrating lifestyle interventions into routine care.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Lifestyle Intervention for People With Severe Obesity and Serious Mental Illness.

People with serious mental illness experience elevated severe obesity rates, yet limited evidence documents whether lifestyle intervention participation can benefit these individuals. This study examined the impact of the In SHAPE lifestyle intervention on weight loss among participants with serious mental illness and severe obesity (BMI ≥40) compared with participants who are overweight (BMI 25 to <30) and have class I (BMI 30 to <35) or class II (BMI 35 to <40) obesity. Data were combined from three trials of the 12-month In SHAPE intervention for individuals with serious mental illness collected between 2007 and 2013 and analyzed in 2014. In SHAPE includes individual weekly meetings with a fitness trainer, a gym membership, and nutrition education. The primary outcome was weight loss. Secondary outcomes were fitness, blood pressure, lipids, and program adherence. Participants (N=192) were diagnosed with schizophrenia spectrum (53.1%) or mood (46.9%) disorders. At 12 months, the overall sample showed significant weight loss, but differences among BMI groups were not significant (severe obesity, 2.57% [7.98%]; class II, 2.26% [8.69%]; class I, 1.05% [6.86%]; overweight, 0.83% [7.62%]). One third of participants with severe obesity achieved ≥5% weight loss, which was comparable across groups. More participants with severe obesity achieved ≥10% weight loss (20%) than overweight (2.9%, p=0.001) and class I (5.9%, p<0.001), but not class II (17.8%, p=0.974), obesity groups. People with severe obesity and serious mental illness benefit similarly to those in lower BMI groups from lifestyle intervention participation.

Quality improvement in diabetes--successful in achieving better care with hopes for prevention.

Diabetes affects 29 million Americans and is associated with billions of dollars in health expenditures and lost productivity. Robust evidence has shown that lifestyle interventions in people at high risk for diabetes and comprehensive management of cardiometabolic risk factors like glucose, blood pressure, and lipids can delay the onset of diabetes and its complications, respectively. However, realizing the "triple aim" of better health, better care, and lower cost in diabetes has been hampered by low adoption of lifestyle interventions to prevent diabetes and poor achievement of care goals for those with diabetes. To achieve better care, a number of quality improvement (QI) strategies targeting the health system, healthcare providers, and/or patients have been evaluated in both controlled trials and real-world programs, and have shown some successes, though barriers still impede wider adoption, effectiveness, real-world feasibility, and scalability. Here, we summarize the effectiveness and cost-effectiveness data regarding QI strategies in diabetes care and discuss the potential role of quality monitoring and QI in trying to implement primary prevention of diabetes more widely and effectively. Over time, achieving better care and better health will likely help bend the ever-growing cost curve.

Randomized Controlled Trial of a Healthy Lifestyle Intervention Among Smokers With Psychotic Disorders.

People with severe mental disorders typically experience a range of health problems; consequently, interventions addressing multiple health behaviors may provide an efficient way to tackle this major public health issue. This two-arm randomized controlled trial among people with psychotic disorders examined the efficacy of nicotine replacement therapy (NRT) plus either a face-to-face or predominantly telephone delivered intervention for smoking cessation and cardiovascular disease (CVD) risk reduction. Following baseline assessment and completion of a common, individually delivered 90-minute face-to-face intervention, participants (n = 235) were randomized to receive NRT plus: (1) a "Healthy Lifestyles" intervention for smoking cessation and CVD risk behaviors or (2) a predominantly telephone-based intervention (designed to control for NRT provision, session frequency, and other monitoring activities). Research assistants blind to treatment allocation performed assessments at 15 weeks (mid-intervention) and 12 months after baseline. There were no significant differences between intervention conditions in CVD risk or smoking outcomes at 15 weeks or 12 months, with improvements in both conditions (eg, 12 months: 6.4% confirmed point prevalence abstinence rate; 17% experiencing a 50% or greater smoking reduction; mean reduction of 8.6 cigarettes per day; mean improvement in functioning of 9.8 points). The health disparity experienced by people with psychotic disorders is high. Face-to-face Healthy Lifestyle interventions appear to be feasible and somewhat effective. However, given the accessibility of telephone delivered interventions, potentially combined with lower cost, further studies are needed to evaluate telephone delivered smoking cessation and lifestyle interventions for people with psychotic disorders.
