Impact of an Adaptive Worksite Diabetes Prevention Trial on Health Action Process Approach Outcomes Regarding Dietary Intake and Physical Activity.

Weight loss, through a reduction in energy intake and increase in energy expenditure, can reduce diabetes risk in people with prediabetes. However, lifestyle change can be challenging even with positive intentions. The Health Action Process Approach (HAPA) theoretical framework bridges the intention-behavior gap by targeting planning behaviors and strengthening efficacious beliefs for behavioral change. In the current trial, an adaptive design was employed to examine differences in HAPA measures (i.e., planning and self-efficacy) regarding the target behaviors of dietary intake and physical activity (PA). Adults ≥ 21 years old with overweight or obesity and prediabetes (n = 185) received the standard Group Lifestyle Balance (GLB) intervention during the first month of treatment. Weight loss responders (lost > 2.5% of weight) at week five remained in GLB during weeks 5-16; slow responders (lost ≤ 2.5%) were stratified to the adaptive GLB Plus (GLB+) intervention during weeks 5-16. GLB+ augmented self-regulatory skills and practices consistent with HAPA. We conducted mixed model analyses with a group-by-time interaction for fixed effects at four months. GLB experienced greater improvement in behavioral intention for both diet and PA, planning behaviors (action and coping planning) for diet, and self-efficacy beliefs (action and maintenance self-efficacy) for PA compared to GLB+ (all ps < .0125). However, GLB+ also experienced statistically significant improvement in planning and self-efficacy and in energy intake and food group servings (all ps < .01). Whereas an adaptive intervention can be advantageous in improving HAPA measures and food choices, greater focus on increasing PA is needed. Additional research may help to determine effective PA strategies.

[Arterial hypertension-Current recommendations for action]. / Arterielle Hypertonie ­ aktuelle Handlungsempfehlungen.

Arterial hypertension (aHT) currently affects nearly 1 in every 3 persons in Germany and the number of those affected is steadily increasing. Only half of the patients treated show a controlled blood pressure in the follow-up. A suboptimal treatment involves the danger of cardiovascular and renal events that under certain circumstances can have a fatal course. The publication of the first national treatment guidelines (NVL) on hypertension and the new guidelines of the European Society of Hypertension (ESH) 2023 simultaneously represent two updates. Both emphasize the necessity to avoid hypertension-mediated organ damage (HMOD) and the identification of high blood pressure. The focussing on preventive measures and lifestyle recommendations as well as the simplification of target blood pressure values play important roles in the routine practice. This article provides a practical summary of the current recommendations of both guidelines on the diagnostics and treatment of aNT, discusses relevant differences and provides routinely applicable advice.

Does intervention sequence impact self-regulatory and behavioral outcomes in an adaptive trial among adults with prediabetes?

Background: Lifestyle interventions can promote improvement in dietary intake and physical activity (PA), on average, by strengthening motivation, self-regulatory efforts, and commitment to behavioral change. However, maintenance of behavioral change is challenging, and slow responders during treatment often experience less overall success. Adaptive intervention sequences tailored to treatment response may be more effective in sustaining behavioral change. Methods: Adults ≥ 21 years old with prediabetes (n = 187) were stratified at week five to the standard Group Lifestyle Balance (GLB) intervention, if they achieved > 2.5% weight loss, or to the augmented intervention GLB Plus (GLB+) at week five, if they did not. At month five, each person in a matched pair was randomly assigned to GLB or GLB + for the extended intervention phase (months 5-12) followed by no study conduct (months 13-18). The primary comparison of interest was the change in outcomes between the standard (GLB followed by GLB) and augmented (GLB + followed by GLB+) intervention sequences post-intervention at 12 - and 18-months using linear mixed effect models. Results: The augmented GLB + intervention sequence reported a decline in the change in self-efficacy for reducing fat intake, self-efficacy for 'sticking to' healthy eating and exercise, and hopeful thought and planning compared to the standard GLB intervention sequence (all P < 0.0167) at 18-months. However, there were no significant differences between these intervention sequences at 18-months in the change in dietary intake or minutes of PA (all P > 0.05). Conclusions: No significant change in behavioral measures across intervention sequences occurred at study end. An 18-month decline in self-efficacy regarding diet and PA and hopeful thought and planning among slow responders following no intervention for six months indicates greater extended care is likely needed. The type of extended care that is most effective for slow treatment responders requires additional research.

Associations of combined genetic and lifestyle risks with hypertension and home hypertension.

No study, to our knowledge, has constructed a polygenic risk score based on clinical blood pressure and investigated the association of genetic and lifestyle risks with home hypertension. We examined the associations of combined genetic and lifestyle risks with hypertension and home hypertension. In a cross-sectional study of 7027 Japanese individuals aged ≥20 years, we developed a lifestyle score based on body mass index, alcohol consumption, physical activity, and sodium-to-potassium ratio, categorized into ideal, intermediate, and poor lifestyles. A polygenic risk score was constructed with the target data (n = 1405) using publicly available genome-wide association study summary statistics from BioBank Japan. Using the test data (n = 5622), we evaluated polygenic risk score performance and examined the associations of combined genetic and lifestyle risks with hypertension and home hypertension. Hypertension and home hypertension were defined as blood pressure measured at a community-support center ≥140/90 mmHg or at home ≥135/85 mmHg, respectively, or self-reported treatment for hypertension. In the test data, 2294 and 2322 participants had hypertension and home hypertension, respectively. Both polygenic risk and lifestyle scores were independently associated with hypertension and home hypertension. Compared with those of participants with low genetic risk and an ideal lifestyle, the odds ratios for hypertension and home hypertension in the low genetic risk and poor lifestyle group were 1.94 (95% confidence interval, 1.34-2.80) and 2.15 (1.60-2.90), respectively. In summary, lifestyle is important to prevent hypertension; nevertheless, participants with high genetic risk should carefully monitor their blood pressure despite a healthy lifestyle.

Optimizing outcomes in men with prostate cancer: the cardiovascular event lowering (CaELo) pathways.

INTRODUCTION: Risk of cardiovascular disease is higher among men with prostate cancer than men without, and prostate cancer treatments (especially those that are hormonally based) are associated with increased cardiovascular risk. MATERIALS AND METHODS: An 11-member panel of urologic, medical, and radiation oncologists (along with a men's health specialist and an endocrinologist/preventive cardiologist) met to discuss current practices and challenges in the management of cardiovascular risk in prostate cancer patients who are taking androgen deprivation therapies (ADT) including LHRH analogues, alone and in combination with androgen-targeted therapies (ATTs). RESULTS: The panel developed an assessment algorithm to categorize patients by risk and deploy a risk-adapted management strategy, in collaboration with other healthcare providers (the patient's healthcare "village"), with the goal of preventing as well as reducing cardiovascular events. The panel also developed a patient questionnaire for cardiovascular risk as well as a checklist to ensure that all aspects of cardiovascular disease risk reduction are completed and monitored. CONCLUSIONS: Prostate cancer patients receiving ADT with or without ATT need to be more zealously assessed for prevention and aggressively managed to reduce cardiovascular events. This can and should include participation from the entire multidisciplinary healthcare team.

Sex and Socioeconomic Disparities in Dementia Risk: A Population-Attributable Fraction Analysis in Argentina.

INTRODUCTION: Twelve modifiable risk factors (RFs) account for 40% of dementia cases worldwide. However, limited data exist on such factors in middle- and low-income countries. We aimed to estimate the population-attributable fractions (PAFs) for the 12 RFs in Argentina, assessing changes over a decade and exploring socioeconomic and sex influences. METHODS: We conducted cross-sectional analyses of the 12 RFs from Argentinian surveys conducted in 2009, 2015, and 2018, including 96,321 people. We calculated PAFs and stratified estimates based on sex and income. RESULTS: We estimated an overall PAF of 59.6% (95% CI = 58.9-60.3%). The largest PAFs were hypertension = 9.3% (8.7-9.9%), physical inactivity = 7.4% (6.8-8.2%), and obesity = 7.4% (6.8-7.9%). Men were more impacted by excessive alcohol, while women by isolation and smoking. Lower income linked to higher PAFs in education, hypertension, and obesity. DISCUSSION: Argentina has a higher PAF for dementia than the world population, with distinct RF distribution. PAF varied by sex and economic status, advocating tailored prevention strategies.

A Proposal for the Comprehensive Care of Men on Androgen Deprivation Therapy: Recommendations From the Multidisciplinary Prostate Cancer 360 Working Group.

INTRODUCTION: To promote comprehensive care of patients throughout the androgen deprivation therapy (ADT) prescribing process, the Prostate Cancer 360 (PC360) Working Group developed monitoring and management recommendations intended to mitigate or prevent ADT-associated adverse events. METHODS: The PC360 Working Group included 14 interdisciplinary experts with a dedicated clinical interest in prostate cancer and ADT management. The working group defined challenges associated with ADT adverse event management and then collaboratively developed comprehensive care recommendations intended to be practical for ADT prescribers. RESULTS: The PC360 Working Group developed both overarching recommendations for ADT adverse event management and specific recommendations across 5 domains (cardiometabolic, bone, sexual, psychological, and lifestyle). The working group recommends an interdisciplinary, team-based approach wherein the ADT prescriber retains an oversight role for ADT management while empowering patients and their primary and specialty care providers to manage risk factors. The PC360 recommendations also emphasize the importance of proactive patient education that involves partners or other support providers. Recommended monitoring and assessment tools, risk factor management, and patient counseling points are also included for the 5 identified domains, with an emphasis on lifestyle and behavioral interventions that can improve quality of life and reduce the risk for ADT-associated complications. CONCLUSIONS: Comprehensive care of patients receiving ADT requires early and ongoing coordinated management of a variety of health domains, including cardiometabolic, bone, sexual, psychological health. Patient education and primary care provider involvement should begin prior to ADT initiation and continue throughout treatment to improve patient and partner quality of life.

Weight loss maintenance following an augmented intervention for early slow weight loss responders: An adaptive trial.

Early slow weight loss during treatment is associated with less weight loss overall. The impact of an augmented intervention designed for early slow weight loss responders compared with a standard diabetes prevention intervention was evaluated following 12 months of treatment and 6 months of no contact. The impact of standard vs. augmented intervention sequences on weight and glycemia also was determined. Adults were ≥21 years old with overweight or obesity and prediabetes (n = 174). Slow responders were stratified to augmented treatment if they failed to achieve >2.5% weight loss (%WL) at Week 5. Matched within-sex pairs of participants were created based on %WL at Month 5 following the intensive intervention phase, and each person within the pair was randomly assigned to treatment for Months 5-12 during the extended intervention phase. Both 12-month interventions included a ≥7%WL goal. Mean 12-month %WL was 5.29% (95% CI: 4.27%-6.31%; P < .0001) and 18-month %WL was 3.34% (95% CI: 2.01%-4.66%; P < .0001) overall. %WL was greater for the standard (9.55%) than the augmented (4.0%) intervention (P = .0001); no differences occurred in weight regain between early and slow responders (P = .9476). No differences occurred in mean %WL at 12 months between the standard and augmented groups after controlling for %WL at Week 5 and sex (P = .23) nor in the change in glycemia (all P > .05). WL following the first month of treatment predicted 12- and 18-month WL success regardless of intervention sequence; however, even early slow responders achieved significant WL during treatment. Further research is needed to support effective WL maintenance for people with prediabetes.

Weight loss is a primary strategy for risk reduction in adults with prediabetes, and early weight loss may indicate weight loss success long-term. Early slow weight loss responders during behavioral treatment may benefit from alternate treatment compared with remaining in a standard diabetes prevention program. An intervention augmented with training in goal setting and problem-solving was implemented among slow weight loss responders following the first month of treatment in the current study. The change in percent weight loss observed in the augmented intervention compared with the standard diabetes prevention intervention was determined at 12 and 18 months from baseline. Both the standard and augmented interventions facilitated significant weight loss at 12 months. Participants who lost more than 2.5% of their weight during the first month of treatment (early responders) lost more weight overall during the study compared with people who were slower to respond. Percent weight loss following the first month of lifestyle intervention and sex predicted percent weight loss at 12 months. Participants regained some weight at 18 months regardless of the treatment group but weighed less than their baseline weight. Both early and slow weight loss responders may benefit from ongoing support following 12 months of treatment to achieve weight loss maintenance.

Healthier Energy Balance Behaviors Most Important for Health-Related Quality of Life in Rural Cancer Survivors in Central Pennsylvania.

BACKGROUND: Rural cancer survivors face a greater number of health disparities, including poorer health-related quality of life (HRQoL), than urban cancer survivors. Engagement in healthy lifestyle behaviors also varies between rural and urban cancer survivors. Lifestyle behaviors can improve HRQoL; however, the combination of behaviors most important for HRQoL in rural survivors is unclear. This study examined clusters of lifestyle behaviors in rural cancer survivors, and differences in HRQoL between behavioral clusters. METHODS: Rural cancer survivors in the United States (N = 219) completed a cross-sectional survey. Lifestyle behaviors were classified into unhealthy/healthy binary categories (inactive/active, longer/shorter sedentary time, excessive/acceptable fat intake, very low/higher fruit and vegetable intake, some/no alcohol consumption, and poor/good sleep quality). Behavioral clusters were identified by latent class analysis. HRQoL differences between behavioral clusters were assessed by ordinary least squares regression. RESULTS: The 2-class model demonstrated the best fit and interpretability. The "mostly unhealthy behaviors" class (38.5% of sample) had higher probabilities of all unhealthy behaviors, except alcohol consumption. The "healthier energy balance" class (61.5% of sample) had higher probabilities of active, shorter sedentary, higher fruit and vegetable consumption, excessive fat intake, some alcohol consumption, and poor sleep categories, and reported better HRQoL. CONCLUSIONS: Healthier energy balance behaviors were particularly relevant for HRQoL in rural cancer survivors. Multiple behavior change interventions to improve HRQoL in rural cancer survivors should focus on supporting energy balance behaviors. Many rural cancer survivors may lead very unhealthy lifestyles, placing them at high risk of adverse outcomes. This subpopulation should be prioritized to help alleviate cancer health disparities.

Impact of an augmented intervention on self-regulatory, dietary and physical activity outcomes in a diabetes prevention trial among adults with prediabetes.

Self-regulation can facilitate modifications in lifestyle to promote behavioral change. However, little is known about whether adaptive interventions promote improvement in self-regulatory, dietary, and physical activity outcomes among slow treatment responders. A stratified design with an adaptive intervention for slow responders was implemented and evaluated. Adults ≥ 21 years old with prediabetes were stratified to the standard Group Lifestyle Balance intervention (GLB; n = 79) or the adaptive GLB Plus intervention (GLB + ; n = 105) based on first-month treatment response. Intake of total fat was the only study measure that significantly differed between groups at baseline (P = 0.0071). GLB reported greater improvement in self-efficacy for lifestyle behaviors, goal satisfaction with weight loss, and very active minutes of activity than GLB + (all P < 0.01) at 4-months. Both groups reported significant improvement in self-regulatory outcomes and reduction in energy and fat intake (all P < 0.01). An adaptive intervention can improve self-regulation and dietary intake when tailored to early slow treatment responders.

[Relationship between cardiovascular risk assessment and health behavior in the light of psychosocial factors.] / A cardiovascularis rizikóbecslés és az egészségmagatartás kapcsolata pszichoszociális tényezok tükrében.

INTRODUCTION: Even though preventive measures have been taken to reduce cardiovascular risk, cardiovascular mortality is increasing. Cardiovascular screening can be a population strategy that contributes to the reduction of mortality over the long term when implemented in a systematic, protocol-based, expanded manner. OBJECTIVE: In this study, we examine changes in participants' health behavior between 2012 and 2019 as a follow-up to the Budakalász Epidemiological Study (BEV). METHOD: A cardiovascular health index was developed to enable effective follow-up. This study included subjects with medium and high cardiovascular risks who participated in the BEV complex cardiovascular risk assessment in 2012 (n = 502). Besides the basic data from the BEV baseline study (demographics, healthy lifestyle, risk behavior, diseases treated by medicine), the 2019 follow-up questionnaire included newly added psychological questionnaires (Perceived Stress, WHO Well-being, Beck Hopelessness Scale, Health-Related Social Support, ABCD Risk Questionnaire). RESULTS: All factors of the cardiovascular health index created in our analysis showed an improvement of over 70% between 2012 and 2019. 37.6% of the participants did something for their health, according to their confession, by 30.3%, BEV had a big or very big impact on their lives from the 2012 BEV test in the year after the test, and by 24.7%, BEV had and still has a big or very big impact on their lives. The improving health indices show a significant correlation with psychological factors. Psychological factors showed a positive correlation with well-being (tau_b = 0.344) and a negative correlation with perceived stress (tau_b = -0.225) and hopelessness (tau_b = -0.206). CONCLUSION: The participants in the study showed a significant change in health behavior seven years after the BEV cardiovascular risk assessment. A higher level of mental well-being is associated with improved values. By analyzing the impact of BEV on the health behavior change and the lifestyle, we can conclude that the cardiovascular risk assessment facilitates health behavior change.

Early and slow weight loss responders' perceptions of an adaptive diabetes prevention trial: A qualitative perspective.

Objective: Behavioural weight loss interventions demonstrate success on average, yet participants who respond more slowly may benefit from an augmented, tailored approach. Thus, an augmented intervention for early, slow weight loss responders was implemented. This qualitative analysis explored participants' perceptions of and experiences of the 12-month weight loss programme to inform future intervention development and implementation. Design: Individual interviews were conducted post-treatment. In-person, in-depth interviews were offered prior to the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic; videoconferencing interviews were offered following the pandemic onset. Setting: A Midwestern US university workplace. Method: Adults ⩾21 years old with overweight or obesity and prediabetes (n = 39) were recruited and volunteered to participate in a semi-structured interview. Results: Content analysis identified recurring themes among early and early slow weight loss responders. Social support received during weekly group sessions was a critical intervention component. Some early slow responders expressed difficulty with self-regulatory strategies such as setting specific yet attainable goals, and requested additional contact prior to the maintenance study phase - treatment randomisation at month 5 disrupted group dynamics. Early slow responders who received the intervention via videoconferencing believed the format interfered with their ability to establish friendships with other participants and gain insight and support from others' lived experiences. Conclusion: Weight loss interventions may be more efficacious when considering participant heterogeneity during implementation of behavioural strategies. Findings suggest early slow weight loss responders may benefit from greater emphasis on goal setting and striving, agentic thinking, and social support. Future research is needed to examine the implications of these insights on intervention outcomes.

Change lifestyle modification plan/transtheoretical model in non-alcoholic simple fatty liver disease: a pilot randomized study.

BACKGROUND: Non-alcoholic simple fatty liver disease patients have very low compliance with almost all types of physical activities. A transtheoretical model-oriented lifestyle modification plan awakens the patient's consciousness in the pre-intention stage. Aim to evaluate whether a management by stages of change plan based on the Transtheoretical Model and Stages of Change promoted behavior change for patients with non-alcoholic simple fatty liver disease. METHODS: Patients with simple fatty liver diagnosed from July to December 2019 were randomly divided into the transtheoretical model and non-transtheoretical model groups. Primary outcome was change in health belief and health behavior based on questionnaires. Secondary outcomes included changes in blood lipids, body mass indexes, and waist circumference 12-months after intervention. RESULTS: Of 200 enrolled patients 194 were analyzed (non-transtheoretical model group n = 98, transtheoretical model group n = 96). After intervention, total health belief scores (120.91 ± 4.94 vs. 118.82 ± 5.48) and total health behavior scores (131.71 ± 5.87 vs. 119.96 ± 7.12) were higher in the transtheoretical model group (all P < 0.05). Blood lipids, body mass index, and waist circumference more obviously improved in the transtheoretical model group (all P < 0.05). CONCLUSION: A transtheoretical model-based lifestyle modification intervention can be effectively applied to patients with non-alcoholic simple fatty liver.

Media use in gynecological and obstetric care and women's perceived level of education received of lifestyle-related risks: A cross-sectional study.

OBJECTIVE: The application of media on lifestyle-related risk factors (LRRFs) by healthcare providers to educate women may improve women's adherence, health literacy, and awareness of LRRFs, as well as offspring's health outcomes. This study investigated whether exposure to media-based education in gynecological and obstetric care is associated with LRRFs perceived levels of education received during pregnancy and lactation. METHODS: We conducted a cross-sectional, observational study across 14 randomly generated sample points in the 12 most populated cities in Baden-Württemberg, southwest Germany. Women were recruited from gynecological and obstetric institutions. Participants were 219 women who met our inclusion criteria and completed the quantitative questionnaire. We applied ordinal logistic regression analyses to calculate odds ratios (ORs) and 95% confidence intervals (CIs) of women's perceived level of education received related to healthcare providers' exposure to media-based education. RESULTS: Media-based education on LRRFs during pregnancy through gynecologists and/or midwives were significantly associated with women's perceived level of education received (gynecologists: OR = 4.26 (95% CI: 2.04, 8.90; p < .001); midwives: OR = 3.86 (95% CI: 1.66, 8.98; p = .002)). Similar results were found for media-based education through gynecologists and/or midwives on LRRFs during lactation and its association with women's self-assessed level of perceived level of education received (gynecologists: OR = 4.76 (95% CI: 2.15, 10.56; p < .001); midwives: OR = 7.61 (95% CI: 3.13, 18.53; p < .001)). CONCLUSIONS: This study suggests that the exposure to media-based education in gynecological and obstetric care increases women's perceived level of education received of LRRFs during pregnancy and lactation. Therefore, it is recommendable to apply media in gynecological and obstetric care settings.

The psychometric properties of a tool to assess brief behaviour change counselling in South Africa.

BACKGROUND: Primary care providers should be competent in brief behaviour change counselling (BBCC). A new model of BBCC was developed in South Africa. Tools are needed for training and research to evaluate BBCC. AIM: To evaluate the validity and reliability of a tool to assess BBCC. SETTING: Primary care providers in Western Cape, South Africa. METHODS: Exploratory sequential mixed methods included initial qualitative feedback from an expert panel to assess validity, followed by quantitative analysis of internal consistency, inter- and intra-rater reliability. Six raters assessed 33 randomly selected audiotapes from a repository of 123 tapes of BBCC at baseline and 1 month later. RESULTS: Changes to the existing tool involved item changes, added items and grammatical as well as layout changes. The 'Assessment of Brief Behavioural Change Counselling' tool (ABC tool) had good overall internal consistency (Cronbach's alpha 0.955), inter-rater (intra-class correlation coefficient [ICC] 0.813 at follow-up) and intra-rater reliability (Pearson's correlation 0.899 and p 0.001). Sub-scores for the Assist (ICC 0.784) and Arrange (ICC 0.704) stages had lower inter-rater reliability than the sub-scores for Ask (ICC 0.920), Alert (ICC 0.925) and Assess (ICC 0.931) stages. CONCLUSION: The ABC tool is sufficiently reliable for the assessment of BBCC. Minor revisions may further improve the reliability of the tool, particularly for the sub-scores measuring Assist and Arrange. The ABC tool can be used in clinical training or research studies to assess fidelity to this model of BBCC.

Lifestyle Risk Factors and Cognitive Outcomes from the Multidomain Dementia Risk Reduction Randomized Controlled Trial, Body Brain Life for Cognitive Decline (BBL-CD).

BACKGROUND/OBJECTIVES: To evaluate the efficacy of a multidomain intervention to reduce lifestyle risk factors for Alzheimer's disease (AD) and improve cognition in individuals with subjective cognitive decline (SCD) or mild cognitive impairment (MCI). DESIGN: The study was an 8-week two-arm single-blind proof-of-concept randomized controlled trial. SETTING: Community-dwelling individuals living in Canberra, Australia, and surrounding areas. PARTICIPANTS: Participants were 119 individuals (intervention n = 57; control n = 62) experiencing SCD or MCI. INTERVENTION: The control condition involved four educational modules covering dementia and lifestyle risk factors, Mediterranean diet, physical activity, and cognitive engagement. Participants were instructed to implement this information into their own lifestyle. The intervention condition included the same educational modules and additional active components to assist with the implementation of this information into participants' lifestyles: dietitian sessions, an exercise physiologist session, and online brain training. MEASUREMENTS: Lifestyle risk factors for AD were assessed using the Australian National University-Alzheimer's Disease Risk Index (ANU-ADRI), and cognition was assessed using Alzheimer's Disease Assessment Scale-Cognitive subscale, Pfeffer Functional Activities Questionnaire, Symbol Digit Modalities Test (SDMT), Trail Making Test-B, and Category Fluency. RESULTS: The primary analysis showed that the intervention group had a significantly lower ANU-ADRI score (χ2 = 10.84; df = 3; P = .013) and a significantly higher cognition score (χ2 = 7.28; df = 2; P = .026) than the control group. A secondary analysis demonstrated that the changes in lifestyle were driven by increases in protective lifestyle factors (χ2 = 12.02; df = 3; P = .007), rather than a reduction in risk factors (χ2 = 2.93; df = 3; P = .403), and cognitive changes were only apparent for the SDMT (χ2 = 6.46; df = 2; P = .040). Results were robust to intention-to-treat analysis controlling for missing data. CONCLUSION: Results support the hypothesis that improvements in lifestyle risk factors for dementia can lead to improvements in cognition over a short time frame with a population experiencing cognitive decline. Outcomes from this trial support the conduct of a larger and longer trial with this participant group.

Factors Affecting Smoking Initiation and Cessation Among Saudi Women Attending Smoking Cessation Clinics.

OBJECTIVES: Smoking is one of the most adaptable risk behaviours associated with increased mortality rates, yet over one billion individuals worldwide are smokers. This study aimed to examine self-reported reasons for starting and quitting smoking among women attending smoking cessation clinics in Saudi Arabia. METHODS: This cross-sectional study took place between January 2014 and January 2017 in Saudi Arabia using previously collected data. A survey was distributed to 3,000 female smokers attending smoking cessation programmes in 18 clinics from different regions in Saudi Arabia to determine self-reported reasons for smoking initiation and willingness/unwillingness to quit. RESULTS: A total of 2,190 women participated in the study (response rate = 73%). Overall, the most common reason for starting to smoke was friends (31.1%), while the predominant reason for willingness to quit was health concerns (45.5%). The most frequent reason for being unwilling to quit smoking was a fear of mood changes (28%). CONCLUSION: Most Saudi women are socially-driven to start smoking, while the most common reason for quitting is health concerns. The latter finding is promising in that it shows that smokers are gaining awareness of the adverse effects of smoking.

Effectiveness of universal multiple-risk lifestyle interventions in reducing depressive symptoms: Systematic review and meta-analysis.

Though many studies have explored the association between single-risk lifestyle interventions and depression, unhealthy lifestyle factors often co-occur, with adults engaging in two or more risk behaviours. To date, little is known about the effectiveness of universal multiple-risk lifestyle interventions to reduce depressive symptoms. We conducted a SR/MA to assess the effectiveness of universal multiple-risk lifestyle interventions (by promoting a healthy diet, physical activity and/or smoking cessation) to reduce depressive symptoms in adults. We searched MEDLINE, Scopus, CENTRAL, PsycINFO, WOS, OpenGrey, the ICTRP and other sources from inception to 16 September 2019. We selected only randomized controlled trials, with no restrictions on language or setting. Our outcome was the reduction of depressive symptoms. We calculated the standardized mean difference using random-effect models. Sensitivity, sub-group and meta-regression analyses were performed. Of the 9386 abstracts reviewed, 311 were selected for full-text review. Of these, 23 RCTs met the inclusion criteria, including 7558 patients from four continents. Twenty RCTs provided valid data for inclusion in the meta-analysis. The pooled SMD was -0.184 (95% CI, -0.311 to -0.057; p = 0.005). We found no publication bias, but heterogeneity was substantial (I2 = 72%; 95% CI: 56% to 82%). The effectiveness disappeared when only studies with a low risk of bias were included. The quality of evidence according GRADE was low. Although a small preventive effect was found, the substantial heterogeneity and RCTs with lower risk of bias suggested no effectiveness of universal multiple-risk lifestyle interventions in reducing depressive symptoms in a varied adult population. Further evidence is required.

Selecting the optimal risk threshold of diabetes risk scores to identify high-risk individuals for diabetes prevention: a cost-effectiveness analysis.

AIMS: Although risk scores to predict type 2 diabetes exist, cost-effectiveness of risk thresholds to target prevention interventions are unknown. We applied cost-effectiveness analysis to identify optimal thresholds of predicted risk to target a low-cost community-based intervention in the USA. METHODS: We used a validated Markov-based type 2 diabetes simulation model to evaluate the lifetime cost-effectiveness of alternative thresholds of diabetes risk. Population characteristics for the model were obtained from NHANES 2001-2004 and incidence rates and performance of two noninvasive diabetes risk scores (German diabetes risk score, GDRS, and ARIC 2009 score) were determined in the ARIC and Cardiovascular Health Study (CHS). Incremental cost-effectiveness ratios (ICERs) were calculated for increasing risk score thresholds. Two scenarios were assumed: 1-stage (risk score only) and 2-stage (risk score plus fasting plasma glucose (FPG) test (threshold 100 mg/dl) in the high-risk group). RESULTS: In ARIC and CHS combined, the area under the receiver operating characteristic curve for the GDRS and the ARIC 2009 score were 0.691 (0.677-0.704) and 0.720 (0.707-0.732), respectively. The optimal threshold of predicted diabetes risk (ICER < $50,000/QALY gained in case of intervention in those above the threshold) was 7% for the GDRS and 9% for the ARIC 2009 score. In the 2-stage scenario, ICERs for all cutoffs ≥ 5% were below $50,000/QALY gained. CONCLUSIONS: Intervening in those with ≥ 7% diabetes risk based on the GDRS or ≥ 9% on the ARIC 2009 score would be cost-effective. A risk score threshold ≥ 5% together with elevated FPG would also allow targeting interventions cost-effectively.
