Behavioral Lifestyle Interventions for Weight Loss in Overweight or Obese Patients with Type 2 Diabetes: A Systematic Review of the Literature.

PURPOSE OF REVIEW: Around 80-90% of patients with type 2 diabetes mellitus (T2DM) are overweight or obese, presenting a greater risk for serious health complications and mortality. Thus, weight loss represents a main goal for T2DM management. Although behavioral lifestyle interventions (BLIs) could help promoting weight loss in T2DM patients with overweight or obesity, their effectiveness is still controversial. This systematic review offers an updated and comprehensive picture of BLIs according to Michie's classification in T2DM patients with overweight or obesity and identifies possible factors (related to both patients and interventions) associated with weight loss. The PRISMA guidelines were followed. The literature search till March 2023 indicated 31 studies involving 42 different BLIs. RECENT FINDINGS: Our findings suggest that structured BLIs, characterized by frequent feedback and support, can lead to a clinically meaningful 5% weight loss, regardless of specific behavioral, diet, and physical activity components. Further research should address methodological issues and heterogeneity of interventions, also considering the effect of pharmacological therapies on weight reduction. Lastly, more attention should be paid to the long-term effectiveness of behavioral lifestyle interventions and to the relationship between weight loss and diabetes.

The role of social support in the relation between chronotype and mental health in a cohort of women from the American Heart Association Go Red for Women Strategically Focused Research Network.

Women are disproportionally affected by psychological distress and lack of social support and are more vulnerable to the negative impact of chronotype on mental health. This study evaluates cross-sectional associations between chronotype and mental health, while assessing the mediating role of social support among women from diverse racial/ethnic backgrounds. Women from the American Heart Association Go Red for Women Research Network were included (N = 506, mean age = 37 ± 15.7, 61% racial/ethnic minority). Chronotype, depression, perceived stress, health-related quality of life, and social support were assessed at baseline using validated self-reported questionnaires. Linear regression and causal mediation analyses were performed. Depression and negative emotionality were higher among women with evening vs. morning/intermediate chronotypes (all p < 0.05). Multivariable analyses adjusted for sociodemographic and clinical confounders showed associations between evening chronotype and higher depression (p = 0.004) and negative emotionality (p = 0.010). However, these associations were no longer significant after adjusting for social support (depression: p = 0.12; negative emotionality: p = 0.18). Social support significantly mediated 44.6% and 45.8% of the total effect of chronotype on depression and negative emotionality, respectively. Social support represents a potential mechanism underlying the associations between eveningness and poor mental health. Chronotype and social support should be considered in interventions for the promotion of mental health in women.

The effects of sustained mild sleep restriction on stress and distress among healthy adults: Findings from two randomized crossover studies.

OBJECTIVE/BACKGROUND: Experimental studies suggest that sleep loss affects psychological outcomes. However, most studies focus on acute severe in-laboratory sleep restriction, with limited ecological validity. This study examines the impact of sustained mild sleep restriction (SR) on stress and distress among healthy adults in a naturalistic home environment. PATIENTS/METHODS: We analyzed data from two randomized crossover studies. Individuals who regularly slept 7-9 h/night completed two 6-wk intervention phases separated by a 6-wk washout: habitual sleep (HS: maintenance of habitual bed and wake times) and SR (delayed bedtime by 1.5 h/night and maintenance of habitual wake time). Adherence to sleep duration requirements was verified with wrist actigraphy and daily sleep diaries during each intervention phase. Measures of perceived stress, subjective anxiety, subjective depression, rumination, and cortisol were collected at baseline and endpoint of each intervention phase. RESULTS: Sixty-two participants (age 36.4 ± 14.0 y, 85.5 % women, 63.3 % racial/ethnic minority) were included in our analyses. Mean total sleep time was 7.4 ± 0.4 h/night during HS and 6.2 ± 0.4 h/night during SR (p < 0.001). Higher perceived stress (3.6 ± 1.0, p = 0.0007) and subjective anxiety (1.1 ± 0.5, p = 0.039) were observed after SR compared to HS. No effect of sleep condition was observed on subjective depression, rumination, and cortisol. CONCLUSIONS: Our findings suggest that prolonged mildly insufficient sleep, similar to what commonly experienced in the real world, can lead to increased perceived stress and subjective anxiety in healthy adults. Addressing sleep loss, even if mild, should be a key component of interventions aimed at promoting mental health in the general population.

The Association Between Ultra-Processed Food Consumption and Chronic Insomnia in the NutriNet-Santé Study.

BACKGROUND: The consumption of ultra-processed foods (UPF) is on the rise worldwide, and it has been linked to numerous health conditions, such as diabetes, obesity, and cancer. Few studies have focused on the effect of UPF consumption on sleep health and even fewer on chronic insomnia. OBJECTIVE: This study investigated the association between UPF intake and chronic insomnia in a large population-based sample. DESIGN: This was a cross-sectional analysis using the NutriNet-Santé study data, an ongoing Web cohort in France. PARTICIPANTS/SETTING: Thirty-eight thousand five hundred seventy adult males and females who had completed a sleep questionnaire (2014) and at least two 24-hour dietary records were included in the analysis. MAIN OUTCOMES MEASURES: Chronic insomnia was defined according to established criteria. Categorization of food and beverages as UPF was based on the NOVA-Group 4 classification. STATISTICAL ANALYSES PERFORMED: The cross-sectional association between UPF intake and chronic insomnia was assessed using multivariable logistic regression. RESULTS: Among the 38,570 participants (mean age, 50.0 ±14.8 years, 77.0% female) included in the analysis, 19.4% had symptoms of chronic insomnia. On average, UPF represented 16% of the total amount (g/day) of the overall dietary intake. In the fully adjusted model, UPF consumption was associated with higher odds of chronic insomnia (odds ratio [OR] for an absolute 10% greater UPF intake in the diet = 1.06; 95% confidence interval [CI]: 1.02-1.09). Sex-specific OR for chronic insomnia for an absolute 10% greater UPF intake in the diet were 1.09 (1.01-1.18) among males and 1.05 (1.01-1.09) among females. CONCLUSIONS: This large epidemiological study revealed a statistically significant association between UPF intake and chronic insomnia, independent of sociodemographic, lifestyle, diet quality, and mental health status covariates. The findings provide insights for future longitudinal research as well as nutrition- and sleep-focused intervention and prevention programs.

The effects of insufficient sleep and adequate sleep on cognitive function in healthy adults.

STUDY OBJECTIVES: Although sleep affects a range of waking behaviors, the majority of studies have focused on sleep loss with relatively little attention on sustained periods of adequate sleep. The goal of this study was to use an experimental design to examine the effect of both of these sleep patterns on cognitive performance in healthy adults. METHODS: This study used a randomized crossover design. Participants who regularly slept 7-9 hours/night completed two 6-week intervention conditions, adequate sleep (maintenance of habitual bed/wake times) and insufficient sleep (reduction in sleep of 1.5 hours relative to adequate sleep), separated by a 2-6weeks (median=43days) washout period. Cognitive functioning was evaluated at baseline and endpoint of each intervention using the NIH Toolbox Cognition Battery. General linear models contrasted scores following each condition to the baseline of the first condition; the baseline of the second condition was included to evaluate practice effects. RESULTS: Sixty-five participants (age 35.9 ± 4.9years, 89% women, 52% non-White race/ethnicity) completed study procedures. There was improvement in performance on the List Sorting Working Memory task after the adequate sleep condition that exceeded practice effects. Cognitive performance after insufficient sleep did not reach the level expected with practice and did not differ from baseline. A similar pattern was found on the Flanker Inhibitory Control and Attention task. CONCLUSIONS: These findings contribute to our understanding of the complex interplay between sleep and cognition and demonstrate that consistent, stable sleep of at least 7 hours/night improves working memory and response inhibition in healthy adults. CLINICAL TRIAL REGISTRATION: The manuscript reports on data from two clinical trials: Impact of Sleep Restriction on Performance in Adults (URL: https://clinicaltrials.gov/ct2/show/NCT02960776, ID Number: NCT02960776) and Impact of Sleep Restriction in Women (URL: https://clinicaltrials.gov/ct2/show/NCT02835261, ID Number: NCT02835261).

Well-being therapy and sleep hygiene in a non-clinical population of adults reporting poor sleep quality and distress: A remote pilot randomized controlled study.

OBJECTIVES: This pilot randomized controlled study evaluates the feasibility and preliminary efficacy of a 7-week remote intervention combining well-being therapy and sleep hygiene to improve sleep and psychological outcomes among adults reporting poor sleep and distress. METHODS: Thirty-one participants (81% women, 40.2 ± 13.0 y, 48% racial/ethnic minority) were recruited from the community during the COVID-19 pandemic through online and local advertisement, and randomized to well-being therapy+sleep hygiene or sleep hygiene-only. Study outcomes were evaluated by self-reported questionnaires administered at baseline and post-intervention and a daily sleep diary. RESULTS: Compared to sleep hygiene-only, well-being therapy+sleep hygiene led to greater improvements in wake after sleep onset (time-by-group interaction: 3.6 ± 1.5 min, p = .017), personal growth (ß -3.0, 95%CI -5.2, -0.8, p = .01), and purpose in life (ß -3.5, 95%CI -6.1, -0.9, p = .009). Anxiety, perceived stress, sleep quality, and insomnia symptoms improved similarly in both groups (between-group differences, p > .05). Improvements in sleep quality, insomnia, and sleep duration were associated with reductions in multiple measures of psychological distress (all p < .05). CONCLUSIONS: These findings suggest that, in a non-clinical setting of individuals suffering from combined poor sleep and psychological distress, the addition of well-being therapy to sleep hygiene may provide additional benefits for sleep by promoting sleep continuity and well-being.

Psychosocial factors are associated with sleep disturbances and evening chronotype among women: A brief report from the American Heart Association Go Red for Women Strategically Focused Research Network.

OBJECTIVES: To evaluate associations between psychosocial factors and sleep characteristics commonly linked to cardiovascular disease risk among racially/ethnically diverse women. METHODS: Women from the AHA Go Red for Women cohort (N = 506, 61% racial/ethnic minority, 37 ± 16years) were assessed using self-reported questionnaires. Logistic regression models were adjusted for age, race, ethnicity, education, and insurance. RESULTS: Women with depression had ∼3-fold higher odds of short sleep (95%CI=1.69-4.61), 2-fold higher odds of poor sleep quality and obstructive sleep apnea risk (95%CI=1.42-3.70 and 1.34-4.24), 4-fold higher odds of insomnia (95%CI=2.42-6.59), and greater likelihood of having an evening chronotype (OR:2.62, 95%CI=1.41-4.89). Low social support was associated with insomnia (OR:1.79, 95%CI=1.18-2.71) and evening chronotype (OR:2.38, 95%CI=1.35-4.19). Caregiving was associated with short sleep (OR:1.73, 95%CI=1.08-2.77) and obstructive sleep apnea risk (OR:2.46, 95%CI=1.43-4.22). CONCLUSIONS: Depression, caregiver strain, and low social support are significantly associated with poor sleep and evening chronotype, highlighting a potential mechanism linking these psychosocial factors to cardiovascular disease risk.

Promoting weight loss and psychological well-being in patients with obesity: A sequential combination of behavioural lifestyle intervention and well-being therapy.

Behavioural lifestyle interventions focused on diet and physical activity are a cornerstone for the treatment of obesity. However, their effects vary substantially across individuals in terms of magnitude and durability. Personalized approaches that target psychological well-being may be promising to facilitate healthy behaviours and sustained weight loss. This preliminary study aimed to explore whether the sequential combination of behavioural lifestyle intervention (BLI) and well-being therapy (WBT) may result in more favourable outcomes than BLI alone in promoting weight loss (primary outcome) and improving psychological well-being, distress, dietary behaviours and physical activity (secondary outcomes). A total of 83 patients with obesity were randomly assigned to BLI/WBT (N = 38) or BLI group (N = 45). The BLI group received a 12-week behavioural weight loss programme, whereas the BLI/WBT group received the same programme followed by an additional 4-week WBT, adapted for group interventions. Data were collected at pretreatment (baseline, T1), at the end of BLI/WBT (T2), at 6-month (T3) and 12-month (T4) follow-ups. There was a significant weight loss in both treatment groups at T2, T3 and T4. The BLI/WBT group showed greater improvements in depressive symptoms at T3 and T4, in autonomy at T2, in personal growth at T4 and in global well-being at T4 compared with BLI group. WBT yielded no additional effect on weight loss. However, the secondary outcomes indicate that WBT may have enduring effects that reduce vulnerability to psychological distress in patients with obesity. In order to confirm these preliminary findings and explore whether a more intensive and individualized WBT can foster sustained weight loss, future studies are needed.

Intuitive and mindful eating to improve physiological health parameters: a short narrative review of intervention studies.

OBJECTIVES: This brief narrative review aims to give an up-to-date overview of intuitive and mindful eating (I/ME) interventions with specific focus on cardiometabolic risk factors, including glucose, lipid profile, blood pressure and inflammatory markers. CONTENT: I/ME intervention studies in adults which measured at least one physiological parameter other than weight were identified from PubMed. The clinical trial/randomized controlled trial filters and publication dates 2001 through April 2021 with variations of the following keywords were applied: intuitive eating, mindful eating, weight neutral. Ten articles were identified. SUMMARY AND OUTLOOK: Of the 10 studies, seven showed I/ME interventions were more effective than control in at least one cardiometabolic outcome, two showed significant I/ME within-group improvements but no between-group differences, and one showed neither within-group nor between-group differences. Specifically, I/ME improved glucose levels among pregnant women with or without gestational diabetes, lipid profile among adults with overweight or obesity, blood pressure among participants with overweight and inflammatory markers among post-menopausal women with obesity. However, the positive impact of I/ME on each of these cardiometabolic parameters was not consistent across studies: of the six studies that examined glucose regulation, two demonstrated positive outcomes for I/ME group, whereas four found no effect compared to control. Three out of five studies had positive lipid effects, one out of five demonstrated systolic blood pressure (SBP) improvements and one of two showed improvements in inflammatory markers. Given these mixed results, more research is needed to understand the possible effectiveness of I/ME to improve cardiometabolic health.

Negative health outcomes in depressed cardiac patients are associated with both low and high psychological well-being dimensions.

Literature supports the positive effects of psychological well-being (P.W.B.) on health. However, most studies focused on the unitary construct of P.W.B., neglecting the different role played by distinct P.W.B. dimensions on health-related outcomes. The aim of this study was to determine whether unbalanced (i.e. low or high) levels of P.W.B. dimensions could differentially affect cardiac course after acute coronary syndrome (A.C.S.), in terms of participation in secondary prevention (S.P.) and/or survival. The sample included 136 depressed and/or demoralized A.C.S. patients referred for a S.P. program on lifestyle modification, in addition to routine cardiac visits provided by the hospital where they were admitted. Psychological assessment included validated interviews on depression and demoralization, Symptom Questionnaire and Psychological Well-Being scales. 100 patients joined the S.P. program, 36 did not. Logistic regression revealed that older age (B = 0.051; p < 0.05), higher autonomy (B = 0.070; p < 0.05) and lower personal growth (B = -0.073; p < 0.05) levels were associated with non-participation in S.P. Moreover, only among patients who did not join the program, those presenting with an impaired level of P.W.B. 'positive relations' dimension (i.e. below the 25th percentile) showed a worse cardiac prognosis (Log Rank: χ2(1) = 4.654; p = 0.031). Negative health outcomes in depressed cardiac patients, such as non-participation in S.P. and worse cardiac course, are associated with both high and low levels of certain P.W.B. dimensions. Psychotherapeutic approaches geared to a balance in P.W.B. dimensions could represent promising new additions to S.P. programs.

Well-Being Therapy and Lifestyle Intervention in Type 2 Diabetes: A Pilot Randomized Controlled Trial.

OBJECTIVE: This pilot randomized controlled trial evaluates the preliminary efficacy of a 4-month well-being therapy (WBT) and lifestyle intervention among adults with type 2 diabetes and overweight/obesity. METHODS: Fifty-eight patients were recruited from two outpatient clinics and randomized to receive the WBT-lifestyle intervention or the lifestyle intervention alone. Data were collected at baseline (T0), immediate postintervention (T1), 6-month follow-up (T2), and 12-month follow-up (T3). Primary efficacy outcomes included changes in weight, psychological distress, and well-being, whereas secondary efficacy outcomes included changes in lifestyle and physiological parameters. RESULTS: Compared with the lifestyle-alone intervention, the WBT-lifestyle intervention showed greater improvements in depression (p = .009, d = -0.6), hostility (p = .018, d = -0.6), and personal growth (p = .026, d = 0.5) at T1, in self-reported physical activity at T2 (p = .013, d = 0.7) and T3 (p = .040, d = 0.5), and in triglycerides (p = .019, d = -1.12) at T3. There were no differences between treatment groups in weight and other physiological parameters. CONCLUSIONS: These findings suggest that WBT may be a valuable addition to lifestyle interventions for improving short-term psychological outcomes and promoting long-term healthy changes in physical activity, with a potential impact on physiological outcomes.Trial Registration:ClinicalTrials.gov identifier: NCT03609463.

The Role of Psychological Well-Being in Weight Loss: New Insights from a Comprehensive Lifestyle Intervention.

BACKGROUND/OBJECTIVE: Although the literature suggested that impaired psychological well-being (PWB) is associated with obesity, evidence on the role of PWB in weight outcomes is limited and inconclusive. This research aimed to investigate the joint role of PWB in achieving clinically significant weight loss (CWL; loss of 5% of the initial weight) through a comprehensive lifestyle intervention for obesity using a broad-based evaluation. METHOD: This study is a prospective cohort of 96 patients with obesity attending a comprehensive lifestyle intervention for weight loss. Data on weight, lifestyle, PWB, and distress, were collected before and after the intervention. RESULTS: 30.5% of the participants achieved CWL at the end of treatment. A more pronounced increase in autonomy (odds ratio = 0.80 [95% CI: 0.68, 0.93], p ≤ .01) and somatization (odds ratio = 0.83 [95% CI: 0.70, 0.98], p ≤ .05) from pre- to post-treatment were independently associated with a lower probability of CWL. CONCLUSIONS: Unbalanced dimensions of PWB, in particular exceedingly high autonomy, may contribute to a poor weight loss outcome. This study paves the way for the addition of psychotherapeutic strategies geared to euthymia in comprehensive lifestyle intervention.

CONTEXTO/OBJETIVO: Aunque la literatura sugiere que el deterioro del bienestar psicológico (BP) está asociado con obesidad, la evidencia sobre el papel del BP en el peso es limitada. Se investiga el papel del BP en el logro de pérdida de peso clínicamente significativa (PPCS; pérdida del 5% del peso inicial) a través de una intervención integral sobre el estilo de vida con respecto a la obesidad. MÉTODO: Cohorte prospectiva de 96 pacientes con obesidad que asisten a una intervención integral sobre el estilo de vida para la pérdida de peso. Se recolectaron datos sobre peso, estilo de vida, BP y angustia, antes y después de la intervención. RESULTADOS: El 30,5% de los participantes lograron pérdida de peso al final del tratamiento. Mayor aumento de autonomía (razón de momios = 0,80 [IC del 95%: 0,68, 0,93], p ≤ 0,01) y somatización (razón de momios = 0,83 [IC del 95%: 0,70, 0,98], p ≤ 0,05) de antes a después del tratamiento se asociaron de forma independiente con menor probabilidad de PPCS. CONCLUSIONES: Las dimensiones desequilibradas del BP, en particular la autonomía excesivamente alta, pueden contribuir a una pérdida de peso insuficiente. Se allana el camino para añadir estrategias psicoterapéuticas orientadas a la eutimia en la intervención integral en el estilo de vida.

Prodromal Symptoms in Depression: A Systematic Review.

INTRODUCTION: Appraisal of prodromal symptoms of unipolar depression may complement the traditional cross-sectional approach and provide a longitudinal perspective, according to a staging model of the illness. OBJECTIVE: To provide an updated systematic review of clinical studies concerned with prodromal symptoms of unipolar depression, according to PRISMA guidelines. METHODS: Keyword searches were conducted in PubMed, Scopus, and Web of Science. Longitudinal studies on prodromal symptoms and signs in adult patients primarily diagnosed with unipolar depression were selected. Findings were examined separately according to study design (i.e., retrospective or prospective). RESULTS: Twenty-five studies met the criteria for inclusion in this systematic review. Findings indicate that a distinct prodromal symptomatology - commonly characterized by anxiety, tension, irritability, and somatic complaints - exists before the onset of unipolar depression. The duration of the prodromal phase was highly variable across studies, ranging from less than a month to several years. Prodromal symptoms profile and duration were consistent within individuals across depressive episodes. There was a close relationship between prodromal and residual symptoms of the same depressive episode. CONCLUSIONS: The present systematic review addresses an important, and yet relatively neglected, clinical issue that deserves further investigation and may be of immediate practical value. The findings provide challenging insights into the pathogenesis and course of unipolar depression, which may result in more timely and effective treatment of recurrences. The definition of a prodromal phase in depression would benefit from the joint use of symptom identification, biomarkers, and neuroimaging.

Kellner's Symptom Questionnaire, a Highly Sensitive Patient-Reported Outcome Measure: Systematic Review of Clinimetric Properties.

INTRODUCTION: Patient-reported outcomes (PROs) are of increasing importance in clinical medicine. However, their evaluation by classic psychometric methods carries considerable limitations. The clinimetric approach provides a viable framework for their assessment. OBJECTIVE: The aim of this paper was to provide a systematic review of clinimetric properties of the Symptom Questionnaire (SQ), a simple, self-rated instrument for the assessment of psychological symptoms (depression, anxiety, hostility, and somatization) and well-being (contentment, relaxation, friendliness, and physical well-being). METHODS: The PRISMA guidelines were used. Electronic databases were searched from inception up to March 2019. Only original research articles, published in English, reporting data about the clinimetric properties of the SQ, were included. RESULTS: A total of 284 studies was selected. The SQ has been used in populations of adults, adolescents, and older individuals. The scale significantly discriminated between subgroups of subjects in both clinical and nonclinical settings, and differentiated medical and psychiatric patients from healthy controls. In longitudinal studies and in controlled pharmacological and psychotherapy trials, it was highly sensitive to symptoms and well-being changes and discriminated between the effects of psychotropic drugs and placebo. CONCLUSIONS: The SQ is a highly sensitive clinimetric index. It may yield clinical information that similar scales would fail to provide and has a unique position among the PROs that are available. Its use in clinical trials is strongly recommended.

Withdrawal Symptoms after Serotonin-Noradrenaline Reuptake Inhibitor Discontinuation: Systematic Review.

BACKGROUND: Serotonin-noradrenaline reuptake inhibitors (SNRI) are widely used in medical practice. Their discontinuation has been associated with a wide range of symptoms. The aim of this paper is to identify the occurrence, frequency, and features of withdrawal symptoms after SNRI discontinuation. METHODS: PRISMA guidelines were followed to conduct a systematic review. Electronic databases included PubMed, the Cochrane Library, Web of Science, and MEDLINE from the inception of each database to June 2017. Titles, abstracts, and topics were searched using a combination of the following terms: "duloxetine" OR "venlafaxine" OR "desvenlafaxine" OR "milnacipran" OR "levomilnacipran" OR "SNRI" OR "second generation antidepressant" OR "serotonin norepinephrine reuptake inhibitor" AND "discontinuation" OR "withdrawal" OR "rebound." Only published trials in the English language were included. RESULTS: Sixty-one reports met the criteria for inclusion. There were 22 double-blind randomized controlled trials, 6 studies where patients were treated in an open fashion and then randomized to a double-blind controlled phase, 8 open trials, 1 prospective naturalistic study, 1 retrospective study, and 23 case reports. Withdrawal symptoms occurred after discontinuation of any type of SNRI. The prevalence of withdrawal symptoms varied across reports and appeared to be higher with venlafaxine. Symptoms typically ensued within a few days from discontinuation and lasted a few weeks, also with gradual tapering. Late onset and/or a longer persistence of disturbances occurred as well. CONCLUSIONS: Clinicians need to add SNRI to the list of drugs potentially inducing withdrawal symptoms upon discontinuation, together with other types of psychotropic drugs. The results of this study challenge the use of SNRI as first-line treatment for mood and anxiety disorders.

Benzodiazepines as a Monotherapy in Depressive Disorders: A Systematic Review.

BACKGROUND: The aim of this paper was to perform a systematic review and, when feasible, a meta-analysis of randomized controlled trials (RCT) which used benzodiazepines (BZD) as a monotherapy versus placebo, antidepressant drugs (AD), or both. METHODS: Keyword searches were conducted for identifying RCT comparing BZD and AD, and/or placebo in the treatment of depression, using electronic databases from their inception up to April 2017. We selected reports of RCT in which BZD were compared to AD and/or placebo in the treatment of adult patients with a primary diagnosis of depressive disorder or anxious depression. When feasible, data were subjected to meta-analysis. RESULTS: A total of 38 studies met the criteria for inclusion and were then included in the systematic review. Only 1 study concerned a newer AD, fluvoxamine. For the meta-analysis, we submitted data on response rate from 22 RCT, considering BZD versus placebo (8 comparisons) and BZD versus tricyclic antidepressants (TCA) (20 comparisons). There was a lack of significant differences as to response rate between BZD and placebo, as well as between BZD and TCA. Analysis of individual studies disclosed that, in more than half of the studies comparing BZD to TCA and/or placebo, BZD were significantly more effective than placebo and as effective as TCA. CONCLUSIONS: BZD are a therapeutic option in anxious depression and there are no indications that AD are preferable. There is a pressing need for RCT of adequate methodological quality and follow-up comparing BZD to second-generation AD and placebo in anxious depression.

Impact of Depression and Demoralization on Blood Pressure Control in African Americans with Hypertension: Findings from the TRIUMPH Trial.

BACKGROUND: African Americans develop hypertension earlier and have worse cardiovascular outcomes than Caucasians. Accumulating evidence suggests that psychological distress may play a role in the observed racial differences in hypertension. Several studies have investigated the relationship between depression and hypertension while little is still known about the role of demoralization. METHODS: Using data from the Trial Using Motivational Interviewing, Positive Affect, and Self-affirmation in African Americans with Hypertension (TRIUMPH), logistic regression models were used to estimate differences in blood pressure control at 12 months among participants with demoralization, depression, and both conditions. RESULTS: Our logistic models showed that reported psychosocial symptoms significantly differed in predicting success in blood pressure control at 12 months. Contrast analyses showed that, after adjusting for sociodemographic, clinical, and psychosocial variables, demoralized patients were less likely to achieve blood pressure control than participants without affective conditions (p = 0.020). Similar results emerged for patients with depression (p = 0.042) and both conditions (p = 0.022). CONCLUSIONS: Depression can be extremely debilitating and has serious health consequence. Our findings confirm this result and show that, even though depression and demoralization share common features, they are two distinct clinical phenomena with similar negative impact on blood pressure control in African Americans.
