Cognitive deficits, psychopathology, and psychosocial functioning in bipolar mood disorder

BACKGROUND: The nutrition management of patients with malabsorption syndromes due to acquired immunodeficiency syndrome (AIDS) is problematic. The aim of this study was to compare the effects of total parenteral nutrition (TPN) and an oral, semielemental diet (SED) on body weight, body composition, quality of life, survival, and medical costs in AIDS patients with malabsorption. METHODS: This was a prospective, randomized, open-label study performed in outpatients. Twenty-three AIDS subjects (TPN group, 12; SED group, 11) with cryptosporidiosis, microsporidiosis, or malabsorption of unknown cause were randomized and followed. Subjects were prescribed equivalent amounts of formulas of similar composition for 3 months. Monthly estimations of caloric intake, body weight, body composition by bioimpedance analysis, and quality of life were recorded. Nutritional variables were analyzed by repeated-measures analysis of covariance, with the baseline measure as the covariate. Nutrition-related medical costs, survival, and indices of absorptive and immune function were compared, RESULTS: Subjects had lost an average of 1.5 and 1.0 kg body wt/mo for TPN and SED during the 6 months before study entry (p < not significant). The TPN group consumed more total calories than the SED group (p < .05). Weight change during therapy was significantly different from pretreatment in both groups (p < .01 for TPN, p = .023 for SED). The TPN group gained more weight than the SED group (p = .057) and significantly more fat (p = .02), but the changes in body cell mass were similar in the two groups. Changes in weight and body composition correlated with caloric intake but not the mode of feeding. The SED group scored significantly better than the TPN group on a physical functioning subscale of quality of life (p < .01). Survival was similar in the two groups. TPN therapy cost almost four times more than SED. Peripheral blood CD4+ lymphocyte numbers were unaffected by either therapy. Intestinal function was not affected by either therapy. CONCLUSIONS: An oral SED may reverse weight loss and wasting in AIDS patients with malabsorption.     

Tailoring a fruit and vegetable intervention on ethnic identity: Results of a randomized study.

Objective: Many targeted interventions have been developed and tested with African Americans (AA); however, AAs are a highly heterogeneous group. One characteristic that varies across AAs is Ethnic Identity (EI). Little research has been conducted on how to incorporate EI into the design of health messages and programs. Design: We tested whether tailoring a print-based fruit and vegetable (F & V) intervention on EI would enhance program impact. AA adults were recruited from two integrated healthcare delivery systems and then randomized to receive three newsletters focused on F & V behavior change over three months. One set of newsletters was tailored only on demographic and social cognitive variables (control condition), whereas the other (experimental condition) was additionally tailored on EI. Main Outcome Measures: The primary outcome for the study was F & V intake, assessed at baseline and three months later using the composite of two brief self-report frequency measures. Results: A total of 560 eligible participants were enrolled, of which 468 provided complete 3-month follow-up data. The experimental group increased their daily mean F & V intake by 1.1 servings compared to .8 servings in the control group (p = .13). Afrocentric experimental group participants showed a 1.4 increase in F & V servings per day compared to a .43 servings per day increase among Afrocentric controls (p     

Intervention effects of information and self-regulation on eating fruits and vegetables over two years.

Objective: This study tested whether an intervention that combined information with self-regulation strategies had a better effect on eating fruits and vegetables than an information-only intervention. Design: Women between age 30 and 50 (N = 255) participated in a 24-month randomized controlled trial comparing two brief interventions: All participants received the same information intervention; participants in the information plus self-regulation group additionally learned a self-regulation technique that integrates mental contrasting with implementation intentions. Main outcome measures: Participants reported in daily diaries how many servings of fruits and vegetables they ate per day during 1 week at baseline, and in the first week, 1, 2, 4, and 24 months after intervention. Results: Participants in both groups ate more fruits and vegetables (0.47 to 1.00 daily servings) than at baseline during the first 4 months after intervention. Two years later, participants in the information plus self-regulation group maintained the higher intake, whereas participants in the information group returned to baseline levels. Conclusion: Adding self-regulation training to an information intervention increased its effectiveness for long-term behavior change.

Need for cognition as a predictor and a moderator of outcome in a tailored letters smoking cessation intervention.

Objective: To analyze whether baseline need for cognition (NFC) was a predictor or a moderator of treatment outcome in a tailored letters intervention for smoking cessation. Design: A total of 1,499 daily smokers were recruited from general medical practices in Germany within a quasi-randomized trial testing the efficacies of two brief interventions for smoking cessation: (a) computer-generated tailored letters and (b) physician-delivered brief counseling versus assessment-only. For this study, we used data from 1,097 daily smokers who were assigned to the tailored letters or the assessment-only condition. Main Outcome Measures: self-reported 6-month prolonged abstinence from tobacco smoking assessed at 12-, 18-, and 24-month follow-ups, and smoking cessation self-efficacy assessed at 6- and 24-month follow-ups. Results: Baseline NFC predicted 6-month prolonged smoking abstinence (p = .01) and smoking cessation self-efficacy (p .05) but on smoking cessation self-efficacy (p = .05). Tailored letters resulted in higher smoking cessation self-efficacy only for persons with higher NFC. Conclusion: Higher levels of NFC are required to increase smoking cessation self-efficacy in computer-tailored interventions for smoking cessation. Considering an individual's NFC might improve the efficacy of written interventions for smoking cessation. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

A randomized, controlled trial of adding expired carbon monoxide feedback to brief stop smoking advice: Evaluation of cognitive and behavioral effects.

Objective: To determine the effect of adding biomarker feedback (expired air carbon monoxide) to standard quit advice on cognitive antecedents of behavior change and smoking cessation and to identify potential effect moderators and mediators. Design: Smokers (N = 160) were randomized to a control (quit advice plus leaflet) or an intervention condition (as control group plus carbon-monoxide level feedback). Cognitive measures were assessed immediately after the intervention and behavioral measures at 6 months' follow-up. Main Outcome Measures: Primary outcome measures were threat and efficacy appraisal, fear arousal, and intention to stop smoking. Secondary outcome measures were quit attempts within the last 6 months and 7-day point prevalence abstinence. Results: Threat appraisal was significantly enhanced in the intervention compared with the control group, t(158) = 2.29, p = .023, as was intention to stop smoking in the next month, t(151) = 2.9, p = .004. However, this effect on intention to stop smoking was short-lived. Groups did not differ in terms of quit attempts or abstinence at follow-up, but the intervention increased the likelihood of cessation in smokers with higher self-efficacy, χ2(1) = 5.82, p = .016. Conclusions: Carbon-monoxide level feedback enhances the effect of brief quit advice on cognitive antecedents of behavior change and smoking cessation rates but further research is required to confirm the longevity of this effect and its applicability to smokers with low self-efficacy.

The physician-delivered smoking intervention project: Can short-term interventions produce long-term effects for a general outpatient population?

Patterns of smoking cessation using 6- and 12-mo follow-up data are reported for 1,261 primary care patients randomized to 3 physician-delivered smoking interventions: advice only (AO), counseling (CI), and counseling plus availability of nicotine-containing gum (CI?+?NCG). One-week point-prevalence cessation rates at 12 mo did not differ among the interventions: AO (15.2%), CI (12.9%) and CI?+?NCG (16.7%). However, maintained cessation rates (abstinent at both 6 and 12 mo) increased with intervention intensity: AO (6.0%), CI (7.8%), and CI?+?NCG (10.0%): Test of trend χ–2?=?5.06, p?=?.02. CI?+?NCG was significantly higher than AO (p?=?.02). The findings support the following conclusions: Brief physician delivered intervention with availability of nicotine-containing gum can have a beneficial long-term effect on smoking cessation, and cohort data as well as point-prevalence rates are important when assessing the long-term impact of lifestyle interventions.

Demographic and psychosocial predictors of fruit and vegetable intakes differ: implications for dietary interventions

OBJECTIVE: The National Cancer Institute (Rockville, Md) has launched a nationwide initiative--5 A Day for Better Health--to encourage consumption of fruits and vegetables. Because the tastes and culinary uses of fruits and vegetables differ, however, it is not known whether a general 5-A-Day message is an effective intervention strategy. This study examined whether there are differences between the demographic and psychosocial correlates of fruit and vegetable intakes. DESIGN: Data are from the Washington State Cancer Risk Behavior Survey (1995-1996), a cross-sectional, random-digit-dial telephone survey representative of the adult population of Washington State. SUBJECTS/SETTING: Interviews were completed with 1,450 adults. Data were collected about demographic characteristics, health status, health-related behavior, fruit and vegetable intakes, and the following diet-related psychosocial factors: beliefs, motives, barriers, attitudes, and stages of dietary change. STATISTICAL ANALYSES: Multivariate linear regression analysis was used to test whether the associations of demographic characteristics and psychosocial factors with fruit intake differed from associations with vegetable intake. RESULTS: In general, health status, health-related behavior, and psychosocial factors were more strongly associated with fruit intakes than vegetable intakes. For example, regular exercisers consumed 0.44 more daily servings of fruits and 0.36 more servings of vegetables than nonexercisers. Compared with those in the preaction stage of dietary change, adults in the maintenance stage consumed 0.99 more daily servings of fruits and 0.68 more servings of vegetables. Intrinsic motivations for eating a healthful diet (eg, to feel better) were strongly associated with both fruit and vegetable intakes, and these associations were stronger for fruit. Extrinsic motivations were not associated with either fruit or vegetable intakes. APPLICATIONS: Dietary interventions based on a general 5-A-Day message may be more effective in increasing fruit intakes than vegetable intakes. Targeted interventions that focus specifically on vegetables are probably necessary. Intrinsic motives for eating a healthful diet should be key components of interventions to increase fruit and vegetable intakes.     

Psychosocial mediation of fruit and vegetable consumption in the body and soul effectiveness trial.

In this study the authors examined psychosocial variables as mediators for fruit and vegetable (FV) intake in a clustered, randomized effectiveness trial conducted in African American churches. The study sample included 14 churches (8 intervention and 6 control) with 470 participants from the intervention churches and 285 participants from the control churches. The outcome of FV intake and the proposed mediators were measured at baseline and at 6-month follow-up. Structural equation modeling indicated that the intervention had direct effects on social support, self-efficacy, and autonomous motivation; these variables also had direct effects on FV intake. Applying the M. E. Sobel (1982) formula to test significant mediated effects, the authors confirmed that social support and self-efficacy were significant mediators but that autonomous motivation was not. Social support and self-efficacy partially mediated 20.9% of the total effect of the intervention on changes in FV intake. The results support the use of strategies to increase social support and self-efficacy in dietary intervention programs. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The effects of a health promotion-health protection intervention on behavior change: the WellWorks Study

OBJECTIVES: This study assessed the effects of a 2-year integrated health promotion-health protection work-site intervention on changes in dietary habits and cigarette smoking. METHODS: A randomized, controlled intervention study used the work site as the unit of intervention and analysis; it included 24 predominantly manufacturing work sites in Massachusetts (250-2500 workers per site). Behaviors were assessed in self-administered surveys (n = 2386; completion rates = 61% at baseline, 62% at final). Three key intervention elements targeted health behavior change: (1) joint worker-management participation in program planning and implementation, (2) consultation with management on work-site environmental changes, and (3) health education programs. RESULTS: Significant differences between intervention and control work sites included reductions in the percentage of calories consumed as fat (2.3% vs 1.5% kcal) and increases in servings of fruit and vegetables (10% vs 4% increase). The intervention had a significant effect on fiber consumption among skilled and unskilled laborers. No significant effects were observed for smoking cessation. CONCLUSIONS: Although the size of the effects of this intervention are modest, on a populationwide basis effects of this size could have a large impact on cancer-related and coronary heart disease end points.     

One-year outcomes of a randomized clinical trial treating depression in low-income minority women.

This study examines 1-year depressive symptom and functional outcomes of 267 predominantly lowincome, young minority women randomly assigned to antidepressant medication, group or individual cognitive- behavioral therapy (CBT), or community referral. Seventy-six percent assigned to medications received 9 or more weeks of guideline-concordant doses of medications; 36% assigned to psychotherapy received 6 or more CBT sessions. Intent-to-treat, repeated measures analyses revealed that medication (p = .001) and CBT (p = .02) were superior to community referral in lowering depressive symptoms across 1-year follow-up. At Month 12, 50.9% assigned to antidepressants, 56.9% assigned to CBT, and 37.1% assigned to community referral were no longer clinically depressed. These findings suggest that both antidepressant medications and CBT result in clinically significant decreases in depression for low-income minority women.

Fluoxetine, smoking, and history of major depression: A randomized controlled trial.

The study was a randomized placebo-controlled trial testing whether fluoxetine selectively enhances cessation for smokers with a history of depression. Euthymic smokers with (H+, n = 109) or without (H-, n = 138) a history of major depression received 60 mg fluoxetine or placebo plus group behavioral quit-smoking treatment for 12 weeks. Fluoxetine initially enhanced cessation for H+ smokers (p = .02) but subsequently impaired cessation regardless of depressive history. Six months after quit date, fluoxetine-treated participants were 3.3 times more likely to be smoking (p = .02). Further research is warranted to determine why high-dose fluoxetine produces continuing effects that oppose tobacco abstinence. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Education of parents of infants and very young children with asthma: a developmental evaluation of the Wee Wheezers program

A randomized control trial of the Wee Wheezers asthma education program was conducted with 76 children < 7 years of age, 31% of whom were on a medication regimen consistent with mild, 51% with moderate, and 18% with moderately severe/severe asthma. Treatment children showed improved morbidity at 3-month follow-up relative to the changes in the controls: increased symptom-free days in the preceding 2 weeks (mean change of +2.2 vs. -2.6 in the controls; p = .004) and month (+2.0 vs. -3.8; p < .02), fewer nights of parental sleep interruption in a typical week (+0.7 vs. +1.8; p < or = .05), and a trend toward fewer asthma sick days (-0.2 vs +0.7; p = ns). These improvements were accompanied by significantly better parental asthma management compared with controls (more consistent use of preventive medications, p < or = .01; early symptom intervention, [corrected] p < or = .05) and trends toward more restrictions on smoking in the home (p < .07) and decreased parental confusion about asthma treatment (p < .11). This study provides evidence that a multisession program of asthma education for parents can improve parental asthma management and clinical outcomes in very young children and provides information on the validity and sensitivity of various asthma outcome measures in this age group.     

Dietary risk factors for pre-eclampsia among women attending Harare Maternity Hospital, Zimbabwe

OBJECTIVE: To identify specific foods that predispose Zimbabwean women to a higher or lower risk of pre-eclampsia and/or eclampsia. DESIGN: A case control study was implemented. Participants were asked by questionnaire to recall the specific amounts of meats, poultry, fruits, fish, vegetables and dairy products they had consumed in the month prior to giving birth. SETTING: Harare Maternity Hospital, Harare, Zimbabwe between June of 1995 and April of 1996. SUBJECTS: 180 women clinically diagnosed with pre-eclampsia (144) or eclampsia (36), and 194 normotensive women without these conditions. MAIN OUTCOME MEASURES: Pre-eclampsia/eclampsia. RESULTS: There were few associations between consumption of specific food items and the occurrence of pre-eclampsia/eclampsia. Meat and fruit were the only foods found to be significantly associated with pre-eclampsia. Women who consumed 12 or more servings of meat per month were more likely to have pre-eclampsia/eclampsia when compared to women eating 11 servings of meat or less per month. While intake of bananas and mangos was unrelated to risk, women who consumed other fruits (i.e. apples, oranges, grapes, peaches, apricots, paw paw, and plums), were 1.7 (95% CI = 1.0 to 3.1) times more likely to develop pre-eclampsia/eclampsia as women who ate none of these fruits. However, women who consumed relatively large quantities of these fruits were not at a particularly high risk. Increased consumption of kapenta was modestly associated with a decrease in disease risk, but this finding was well within the limits of chance and no association was present with intake of other types of fish. CONCLUSIONS: Our findings suggest that variation in consumption of specific foods do not have a strong effect on the incidence of pre-eclampsia in this population. However, further research involving the use of a more comprehensive dietary measure, biochemical measurements of nutrients, pre-pregnancy assessment and ascertainment of dietary intake prior to the development of pre-eclampsia are needed.     

Addressing heavy drinking in smoking cessation treatment: A randomized clinical trial.

Heavy alcohol use frequently co-occurs with cigarette smoking and may impede smoking cessation. This clinical trial examined whether smoking cessation treatment that incorporates brief alcohol intervention can improve smoking cessation outcomes (7-day verified point prevalence abstinence) and reduce drinks consumed per week. Heavy drinkers seeking smoking cessation treatment were assigned by urn randomization to receive, along with 8 weeks of nicotine replacement therapy, either a 4-session standard smoking cessation treatment (ST, n = 119) or standard treatment of equal intensity that incorporated brief alcohol intervention (ST-BI, n = 117). Across follow-ups over 26 weeks, participants in ST-BI reported approximately 20% fewer drinks per week (p     

Successful hormonal treatment of pulmonary parenchymal endometriosis

OBJECTIVE: Tobacco use and other behavioral factors are associated with chronic back pain. Anecdotes suggest excess caffeine use may also be associated with chronic back pain. We compared caffeine consumption by chronic back pain patients with caffeine consumption by controls. DESIGN: Retrospective case-control study. SETTING: A multispecialty outpatient facility. PATIENTS: Sixty new, consecutive patients with chronic back pain compared to 60 new, consecutive patients without chronic back pain. INTERVENTION: Patients were prospectively asked to complete an intake questionnaire. MAIN OUTCOME MEASURE: Daily caffeine consumption was estimated by analyzing the intake questionnaire. Differences between groups were analyzed by both normal and nonparametric statistics. RESULTS: Consumption of caffeine by patients with chronic back pain averaged 392.4 mg/day. Controls consumed 149.8 mg/ day, a significant difference (p = .0001). Men consumed 86% more caffeine per day than women (p = .02). Age and caffeine consumption showed little correlation (r = .126). CONCLUSIONS: Patients with chronic back pain consume over twice as much caffeine as patients without chronic back pain. Confounding variables and possible mechanisms associating caffeine with chronic back pain are discussed.     

Using the internet to assist smoking prevention and cessation in schools: A randomized, controlled trial.

Objective: To evaluate the impact of a classroom-based, Web-assisted tobacco intervention addressing smoking prevention and cessation with adolescents. Design: A two-group randomized control trial with 1,402 male and female students in grades 9 through 11 from 14 secondary schools in Toronto, Canada. Participants were randomly assigned to a tailored Web-assisted tobacco intervention or an interactive control condition task conducted during a single classroom session with e-mail follow-up. The cornerstone of the intervention was a five-stage interactive Web site called the Smoking Zine (http://www.smokingzine.org) integrated into a program that included a paper-based journal, a small group form of motivational interviewing, and tailored e-mails. Main Outcome Measure: Resistance to smoking, behavioral intentions to smoke, and cigarette use were assessed at baseline, postintervention, and three- and six-month follow-up. Multilevel logistic growth modeling was used to assess the effect of the intervention on change over time. Results: The integrated Smoking Zine program helped smokers significantly reduce the likelihood of having high intentions to smoke and increased their likelihood of high resistance to continued cigarette use at 6 months. The intervention also significantly reduced the likelihood of heavy cigarette use adoption by nonsmokers during the study period. Conclusion: The Smoking Zine intervention provided cessation motivation for smokers most resistant to quitting at baseline and prevented nonsmoking adolescents from becoming heavy smokers at 6 months. By providing an accessible and attractive method of engaging young people in smoking prevention and cessation, this interactive and integrated program provides a novel vehicle for school- and population-level health promotion.

Randomised controlled trial of effect of fruit and vegetable consumption on plasma concentrations of lipids and antioxidants

OBJECTIVES: To determine the extent to which plasma antioxidant concentrations in people with habitual low intake of fruit and vegetables respond to increased intakes of these foods. To examine whether advice to increase fruit and vegetables will result in reduction of concentrations of total and low density lipoprotein cholesterol. DESIGN: Randomised controlled trial in which intervention and control groups were followed up for eight weeks. The intervention group was asked to consume eight servings of fruit and vegetables a day. SETTING: Dunedin, New Zealand. SUBJECTS: Eighty seven subjects with normal lipid concentrations who ate three or fewer servings of fruit and vegetables daily. MAIN OUTCOME MEASURES: Plasma concentrations of vitamin C, retinol, alpha and beta carotene, alpha tocopherol, lipids, and lipoproteins. Dietary intake assessed with diet records over four days. RESULTS: The mean plasma vitamin C, alpha carotene, and beta carotene concentrations increased in parallel with increased dietary intake of fruit and vegetables in the intervention group. Concentrations of retinol, alpha tocopherol, lipids, and lipoproteins remained unchanged despite some increase in dietary vitamin E and a small reduction in saturated fat intake. CONCLUSIONS: Following a recommendation to increase fruit and vegetable consumption produces change in plasma concentrations of vitamin C, alpha carotene, and beta carotene likely to reduce incidence of cancer. More specific dietary advice to modify fat intake may be necessary to reduce the risk of cardiovascular disease mediated by lipoprotein and vitamin E.     

Effects of a brief motivational intervention with college student drinkers.

This study consisted of a randomized controlled trial of a 1-session motivational intervention for college student binge drinkers. Sixty students who reported binge drinking 2 or more times in the past 30 days were randomly assigned to either a no-treatment control or a brief intervention group. The intervention provided students with feedback regarding personal consumption, perceived drinking norms, alcohol-related problems, situations associated with heavy drinking, and alcohol expectancies. At 6-week follow-up, the brief intervention group exhibited significant reductions on number of drinks consumed per week, number of times drinking alcohol in the past month, and frequency of binge drinking in the past month. Estimates of typical student drinking mediated these reductions. This study replicates earlier research on the efficacy of brief interventions with college students and extends previous work regarding potential mechanisms of change.

Randomized controlled trial of behavioral activation smoking cessation treatment for smokers with elevated depressive symptoms.

Objective: Depressive symptoms are associated with poor smoking cessation outcomes, and there remains continued interest in behavioral interventions that simultaneously target smoking and depressive symptomatology. In this pilot study, we examined whether a behavioral activation treatment for smoking (BATS) can enhance cessation outcomes. Method: A sample of 68 adult smokers with mildly elevated depressive symptoms (M = 43.8 years of age; 48.5% were women; 72.7% were African American) seeking smoking cessation treatment were randomized to receive either BATS paired with standard treatment (ST) smoking cessation strategies including nicotine replacement therapy (n = 35) or ST alone including nicotine replacement therapy (n = 33). BATS and ST were matched for contact time and included 8 sessions of group-based treatment. Quit date was assigned to occur at Session 4 for each treatment condition. Participants completed a baseline assessment; furthermore, measures of smoking cessation outcomes (7-day verified point-prevalence abstinence), depressive symptoms (Beck Depression Inventory–II; Beck, Steer, & Brown, 1996), and enjoyment from daily activities (Environmental Reward Observation Scale; Armento & Hopko, 2007) were obtained at 1, 4, 16, and 26 weeks post assigned quit date. Results: Across the follow-ups over 26 weeks, participants in BATS reported greater smoking abstinence (adjusted odds ratio = 3.59, 95% CI [1.22, 10.53], p = .02) than did those in ST. Participants in BATS also reported a greater reduction in depressive symptoms (B = ?1.99, SE = 0.86, p = .02) than did those in ST. Conclusions: Results suggest BATS is a promising intervention that may promote smoking cessation and improve depressive symptoms among underserved smokers of diverse backgrounds.

Sensitivity to change of the Roland-Morris Back Pain Questionnaire: part 2

OBJECTIVE: To determine whether blood pressure is reduced for at least 6 months with an intervention to lower alcohol intake in moderate to heavy drinkers with above optimal to slightly elevated diastolic blood pressure, and whether reduction of alcohol intake can be maintained for 2 years. DESIGN: A randomized controlled trial. METHODS: Six hundred forty-one outpatient veterans with an average intake of 3 or more alcoholic drinks per day in the 6 months before entry into the study and with diastolic blood pressure 80 to 99 mm Hg were randomly assigned to a cognitive-behavioral alcohol reduction intervention program or a control observation group for 15 to 24 months. The goal of the intervention was the lower of 2 or fewer drinks daily or a 50% reduction in intake. A subgroup with hypertension was defined as having a diastolic blood pressure of 90 to 99 mm Hg, or 80 to 99 mm Hg if recently taking medication for hypertension. RESULTS: Reduction in average weekly self-reported alcohol intake was significantly greater (P<.001) at every assessment from 3 to 24 months in the intervention group vs the control group: levels declined from 432 g/wk at baseline by 202 g/wk in the intervention group and from 445 g/wk by 78 g/wk in the control group in the first 6 months, with similar reductions after 24 months. The intervention group had a 1.2/0.7-mm Hg greater reduction in blood pressure than the control group (for each, P = .17 and P = .18) for the 6-month primary end point; for the hypertensive stratum the difference was 0.9/0.7 mm Hg (for each, P = .58 and P = .44). CONCLUSIONS: The 1.3 drinks per day average difference between changes in self-reported alcohol intake observed in this trial produced only small nonsignificant effects on blood pressure. The results from the Prevention and Treatment of Hypertension Study (PATHS) do not provide strong support for reducing alcohol consumption in nondependent moderate drinkers as a sole method for the prevention or treatment of hypertension.
