Food choice among homebound older adults: motivations and perceived barriers.

OBJECTIVES: The purpose of this paper is to identify: motivations and perceived barriers associated with food choices made by homebound older adults; whether motivations and perceived barriers vary according to social demographic characteristics; and whether motivations and perceived barriers are associated with dietary quality. DESIGN: This was an observational study using standard interview methods where participants were administered a questionnaire and completed three 24-hour dietary recalls. SETTING: Participants were interviewed in their homes. PARTICIPANTS: 185 homebound older adults were included. MEASUREMENT: Motivations were assessed using a modification of The Food Choice Questionnaire and perceived barriers were assessed using the Vailas Food Enjoyment Questionnaire. Participants answered questions regarding social demographic characteristics. Dietary quality measures of adequate intakes of calories, protein, vitamin D, and vitamin B12 were obtained from the three 24-hour dietary recalls. RESULTS: Mean age was 78.9; 80% were female; and 36% were African American. Key motivations in food choice included sensory appeal, convenience, and price. Key barriers included health, being on a special diet, and being unable to shop. These varied little by social demographics, except for age. Dietary quality varied according to different motivations and barriers. CONCLUSION: Food choices are based upon a complex interaction between the social and environmental context, the individual, and the food. Efforts to change eating behaviors, especially community-based interventions involving self-management approaches, must carefully take into account individuals' self-perceived motivations and barriers to food selection. Incorporating foods that are tasty, easy to prepare, inexpensive, and that involve caregivers are critical for successful interventions.

Interventions for smokeless tobacco use cessation.

BACKGROUND: Use of smokeless tobacco (ST) can lead to nicotine addiction and long-term use can lead to health problems including periodontal disease and cancer. OBJECTIVES: To assess the effects of behavioural and pharmacologic interventions for the treatment of ST use. SEARCH STRATEGY: We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, CINAHL, Web of Science, PsycINFO, Dissertation Abstracts Online, and Scopus. Date of last search: March, 2007. SELECTION CRITERIA: Randomized trials of behavioural or pharmacological interventions to help users of ST to quit with follow up of at least six months. DATA COLLECTION AND ANALYSIS: Two authors independently extracted data. MAIN RESULTS: Two trials of bupropion SR did not detect a benefit of treatment at six months or longer (Odds Ratio (OR) 0.86, 95% Confidence Interval (CI): 0.47 to 1.57). Four trials of nicotine patch did not detect a benefit (OR 1.16, 95% CI: 0.88 to 1.54), nor did two trials of nicotine gum (OR 0.98, 95% CI: 0.59 to 1.63). There was statistical heterogeneity among the results of 12 behavioural interventions included in the meta-analyses. Six trials showed significant benefits of intervention. In post-hoc subgroup analyses, behavioural interventions which include telephone counselling or an oral examination may increase abstinence rates more than interventions without these components. AUTHORS' CONCLUSIONS: Behavioural interventions should be used to help ST users to quit and telephone counselling or an oral examination may increase abstinence rates. Pharmacotherapies have not been shown to affect long-term abstinence.

Interventions for smokeless tobacco use cessation.

BACKGROUND: Use of smokeless tobacco (ST) can lead to nicotine addiction and health problems including periodontal disease and oral cancer OBJECTIVES: To assess the effects of behavioural and pharmacotherapeutic interventions to treat ST use. SEARCH STRATEGY: We searched the Cochrane Tobacco Addiction Group trials register (February 2004), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library Issue 1, 2004), MEDLINE (January 1966-February 2004), EMBASE (1988-January 2004), CINAHL (1982-February 2004), PsycINFO (1984-February 2004), Database of Abstract of Reviews of Effectiveness (DARE, The Cochrane Library, Issue 1, 2004). SELECTION CRITERIA: Randomized trials of behavioural or pharmacological interventions to help users of ST to quit, with follow-up of at least six months. DATA COLLECTION AND ANALYSIS: Two authors independently extracted data. MAIN RESULTS: One trial of bupropion did not detect a benefit of treatment after six months (Odds Ratio (OR) 1.00, 95% Confidence Interval (CI): 0.23 to 4.37). Three trials of nicotine patch did not detect a benefit (OR 1.16, 95% CI: 0.88 to 1.54), nor did two trials of nicotine gum (OR 0.98, 95% CI: 0.59 to 1.63). There was statistical heterogeneity among the results of eight trials of behavioural interventions included in the meta-analysis. Three trials showed significant benefits of intervention. In a post-hoc analysis the trials of interventions which included an oral examination and feedback about ST-induced mucosal changes had homogeneous results and when pooled showed a significant benefit (OR 2.41 95% CI: 1.79 to 3.24). REVIEWERS' CONCLUSIONS: Behavioural interventions should be used to help ST users to quit. Pharmacotherapies have not been shown to affect long-term abstinence but larger trials are needed.

Persistence of depressive symptoms in adolescents.

To examine factors related to the persistence of depressive symptoms, we used a longitudinal follow-up survey of 1,176 adolescents aged 12 to 18 in the United States who reported notable depressive symptoms at baseline. Adolescents were interviewed by telephone at baseline in 1989 and at follow-up in 1993. The outcome of interest was a self-report measure of depressive symptoms experienced within the past 12 months at follow-up. Overall, 38.5% of adolescents reported persistent depressive symptoms. Marked gender differences were found, with 44.5% of girls reporting notable depressive symptoms at follow-up compared with 28.2% for boys. Moreover, current established smokers or experimenters were significantly more likely to report notable depressive symptoms compared with never smokers (42.2%, 41.4% and 33.6%, respectively). Significant multivariate predictors of notable depressive symptoms at follow-up were female gender, change in sleep problems from 1989 to 1993, change in cigarette smoking status from 1989 to 1993, engaging in physical fights, and lack of participation in sports. Many adolescents report continued depressive symptoms over a period spanning four years. Several predictors of persistent depression were identified that could be important components of interventions targeting depressed adolescents.

Sociodemographic characteristics and drinking status as predictors of older women's health.

As part of a U.S. national survey of women's drinking and life experiences, the authors used responses from a subsample (n = 245) of women aged 55-90 years (M = 65.8 years) to examine the relationship of sociodemographic characteristics (income, marital status, and occupational status) and drinking status to several health outcomes (self-perceived general health, depression, sexual satisfaction, and sexual dysfunction). In all analyses, the authors controlled for respondent age. Results indicated that higher household income predicted greater lifetime and current sexual satisfaction with a partner as well as higher general health ratings. Women drinkers also reported better general health than did abstainers. An interaction between marital status (married or cohabitating vs. nonmarried) and employment status (employed vs. nonemployed) was a predictor of general health ratings. The authors found significant contrasts among the 4 groups when they controlled for age, income, and drinking status: (a) Among the employed respondents, the nonmarried women reported better general health than did the married women; and (b) among nonmarried respondents, the employed women reported better general health than did the nonemployed women.

The efficacies of three relaxation regimens in the treatment of PTSD in Vietnam War veterans.

Ninety male Vietnam veterans with posttraumatic stress disorder (PTSD) were administered relaxation instructions, relaxation instruction with deep breathing exercises, or relaxation instructions with deep breathing training and thermal biofeedback. Improvement appeared on only 4 of the 21 PTSD and physiological dependent variables studied. All 21 Treatment x Time interactions were nonsignificant. This suggests that the treatments were mildly therapeutic, but that the additions of training in deep breathing and thermal biofeedback did not produce improvement beyond that associated with simple instructions to relax in a comfortable chair.
