A population comparison of participants and nonparticipants in a health survey.
(49/6426)
OBJECTIVES: This study examined the characteristics of Air Force recruits willing to take part in a health survey vs those unwilling to participate. METHODS: US Air Force recruits undergoing basic military training (n = 32,144) were surveyed regarding demographic and health variables. RESULTS: Respondents indicating an unwillingness to participate in a health survey reported less healthy lifestyles than those willing to participate. Prediction equations modeling the characteristics of those engaging in 4 risky behaviors were nearly identical regardless of whether those refusing to participate were included. CONCLUSIONS: Results suggest that, despite some low estimates of health behaviors due to response bias, relationships between most risk factors are generally unaffected by those not responding to health surveys.

Can patient satisfaction improve health among patients with angina pectoris?
(50/6426)
OBJECTIVE: To identify and explore the components of patient satisfaction that have the strongest association with health-related quality of life among patients with angina. DESIGN: Cross-sectional study with postal questionnaires sent to patients 6 weeks after discharge from hospital, followed-up by one reminder. SETTING: The Central Hospital of Akershus in Norway. STUDY PARTICIPANTS: All 589 angina patients discharged between January 1 1995 and December 31 1996. The response rate was 67% (n=395). MAIN OUTCOME MEASURES: Physical and mental component summary scales in SF-36. RESULTS: When adjusted for relevant background factors such as age, sex, education, social network, health behaviour and sense of coherence, patient satisfaction explained 9% of the variation in the physical, and 7% of the variation in the mental component summary scales. In particular, satisfaction with medical treatment (P=0.002) and with information (P=0.003) were associated with improved physical and mental health-related quality of life. Patients who experienced their physicians as caring and competent were more likely to be satisfied with the medical treatment and with the information. Sense of coherence contributed to health-related quality of life both directly, and through improving patient satisfaction. CONCLUSION: This cross-sectional study supports the hypothesis that patient satisfaction contributes to both physical and mental health-related quality of life. Other research designs are needed to assess whether the associations identified are truly causal. (+info)
Recent alcohol intake as estimated by the Health Habits and History Questionnaire, the Harvard Semiquantitative Food Frequency Questionnaire, and a more detailed alcohol intake questionnaire.
(51/6426)
Epidemiologic studies often rely on food frequency questionnaires (FFQs) to collect information on alcoholic beverage intake. However, estimation of alcohol intake using FFQs may be of some concern because of limited questions concerning alcohol intake. The authors compared estimates of alcohol intake during the 12-24 months prior to interview obtained from the Health Habits and History Questionnaire and the Harvard Semiquantitative Food Frequency Questionnaire with those from a more extensive alcohol questionnaire, the Drinking Pattern Questionnaire, among 133 healthy subjects (75 men, 58 women) aged 35-73 years, residents of western New York State. Data were collected in 1995 during two separate interviewer-administered computer-assisted interviews conducted approximately 2 weeks apart. For each questionnaire, average daily ounces (1 oz = 30 ml) of alcohol intake from alcoholic beverages were calculated as the product of the reported beverage-specific drink size (ounces) and the average daily frequency of intake multiplied by a factor representing the percentage of alcohol provided by each beverage. Estimates of total alcohol and liquor intake, but not of beer and wine intake, tended to be higher for the Drinking Pattern Questionnaire compared with the FFQs. Spearman's correlation coefficients ranged from 0.69 to 0.84. These results suggest that although the Drinking Pattern Questionnaire produced higher estimates than either FFQ, both FFQs provide a reasonable ranking of participants' alcohol intake. (+info)
Randomized trial testing the effect of peer education at increasing fruit and vegetable intake.
(52/6426)
BACKGROUND: The National Cancer Institute recommends that Americans eat at least five daily servings of fruits and vegetables. National strategies to increase consumption may not reach minority and lower socioeconomic populations. In a randomized trial, peer education was tested for effectiveness at increasing fruit and vegetable intake among lower socioeconomic, multicultural labor and trades employees. METHODS: Employees (n = 2091) completed a baseline survey and received an 18-month intervention program through standard communication channels (e.g., workplace mail, cafeteria promotions, and speakers). Ninety-three social networks (cliques) of employees were identified, which were pair matched on intake. At an interim survey (during months 8 and 9), 11 cliques no longer existed and 41 matched pairs of cliques containing 905 employees remained, with one clique per pair being randomly assigned to the peer education intervention. Employees who were central in the communication flow of the peer intervention cliques served as peer educators during the last 9 months of the intervention program. Fruit and vegetable intake was measured with 24-hour intake recall and with food-frequency questions in baseline, outcome (i.e., at 18 months), and 6-month follow-up surveys. All P values are two-sided. RESULTS: By use of multiple regression, statistically significant overall effects of the peer education program were seen in the intake recall (increase of 0.77 total daily servings; P<.0001) and the food-frequency (increase of 0.46 total daily servings; P =.002) questions at the outcome survey. The effect on the total number of servings persisted at the 6-month follow-up survey when measured by the intake recall (increase of 0.41 total daily servings; P =.034) but not the food-frequency (decrease of 0.04 total daily servings; P =.743) questions. CONCLUSIONS: Peer education appears to be an effective means of achieving an increase in fruit and vegetable intake among lower socioeconomic, multicultural adult employees. (+info)
Trends in perceived cost as a barrier to medical care, 1991-1996.
(53/6426)
OBJECTIVES: This study examined trends in perceived cost as a barrier to medical care. METHODS: The Behavioral Risk Factor Surveillance System was used to analyze monthly telephone survey data from 45 states. RESULTS: Overall, the percentage of persons perceiving cost as a barrier to medical care increased from 1991 until early 1993 and then declined to baseline values in late 1996. Perceived cost was a greater barrier in 1996 than in 1991 for persons with low incomes and for those who were unemployed and uninsured. For self-employed persons, percentages increased until mid-1993 and then remained constant. CONCLUSIONS: Further efforts are needed to improve access to medical care for socially disadvantaged populations. (+info)
Prevalence of self-reported nutrition-related health problems in the Lower Mississippi Delta.
(54/6426)
OBJECTIVES: The purpose of this study was to assess demographic and geographic differences in prevalence of self-reported nutrition-related health problems in Arkansas, Louisiana, and Mississippi. METHODS: The authors analyzed 1991 and 1993 Behavioral Risk Factor Surveillance System data for adults 18 years or older. RESULTS: Less educated African American women and women of other minority groups who were aged 35 to 64 years reported the highest prevalence of health problems. Geographic differences involved prevalence of hypertension, health status, and insurance status. CONCLUSIONS: Specific demographic subgroups and geographic areas with a high risk of health problems are in particular need of targeted interventions. (+info)
Improving the health behaviours of elderly people: randomised controlled trial of a general practice education programme.
(55/6426)
OBJECTIVES: To establish the effect of an educational intervention for general practitioners on the health behaviours and wellbeing of elderly patients. DESIGN: Randomised controlled trial with 1 year follow up. SETTING: Metropolitan general practices in Melbourne, Australia. SUBJECTS: 42 general practitioners and 267 of their patients aged over 65 years. INTERVENTION: Educational and clinical practice audit programme for general practitioners on health promotion for elderly people. MAIN OUTCOME MEASURES: Patients' physical activity, functional status, self rated health, immunisation status, social contacts, psychological wellbeing, drug usage, and rate of influenza vaccination. Primary efficacy variables were changes in outcome measures over 1 year period. RESULTS: Patients in the intervention group had increased (a) walking by an average of 88 minutes per fortnight, (b) frequency of pleasurable activities, and (c) self rated health compared with the control group. No change was seen in drug usage, rate of influenza vaccination, functional status, or psychological wellbeing as a result of the intervention. Extrapolations of the known effect of these changes in behaviour suggest mortality could be reduced by 22% if activity was sustained for 5 years. CONCLUSIONS: Education of the general practitioners had a positive effect on health outcomes of their elderly patients. General practitioners may have considerable public health impact in promotion of health for elderly patients. (+info)
Risk factors for early hospital readmission in patients with AIDS and pneumonia.
(56/6426)
OBJECTIVE: To determine risk factors for early readmission to the hospital in patients with AIDS and pneumonia. DESIGN: Case-control analysis. SETTING: A municipal teaching hospital serving an indigent population. PATIENTS: Case patients were all AIDS patients hospitalized with Pneumocystis carinii pneumonia or bacterial pneumonia between January 1992 and March 1995 who were readmitted for any nonelective reason within 2 weeks of discharge (n = 90). Control patients were randomly selected AIDS patients admitted during the study period who were not early readmissions (n = 87), matched by proportion of Pneumocystis carinii to bacterial pneumonia. MEASUREMENTS AND MAIN RESULTS: Demographics, social support, health-related behaviors, clinical aspects of the acute hospitalization, and general medical status were the main predictors measured. RESULTS: Patients were at significantly increased risk of early readmission if they left the hospital unaccompanied by family or friend (odds ratio [OR] 4.76; 95% confidence interval [CI] 2.06, 11.0; p =.0003), used crack cocaine (OR 3.40; 95% CI 1.02, 11.3; p =. 046), had one or more coincident AIDS diagnoses (OR 3.65; 95% CI 1. 44, 9.26; p =.0065), or had been admitted in the preceding 6 months (OR 2.82; 95% CI 1.21, 6.57; p =.016). Demographic characteristics, alcoholism, intravenous drug use, illness severity on admission, and length of hospitalization did not predict early readmission. CONCLUSIONS: Absence of companion at discharge and crack use were important risk factors for early readmission in patients with AIDS and pneumonia. Additional AIDS comorbidity and recent antecedent hospitalization were also risk factors; however, demographics and measures of acute illness during index hospitalization did not predict early readmission.
