Client satisfaction with the nutrition education component of the California WIC program.

Past evaluation research has documented improved nutritional outcomes resulting from participation in the Special Supplemental Nutrition Program for Women, Infants and Children (WIC). However, these evaluations have not examined the program from the clients' perspective, nor have they examined the independent effect of the nutrition education component. The purpose of this study was to quantitatively and qualitatively examine client satisfaction with the nutrition education component of the California WIC program. The methodology consisted of two phases. During phase I of the study (the quantitative component), participants completed Client Satisfaction Surveys immediately following attendance of one nutrition class. During phase II (the qualitative component), four focus groups were conducted. All subjects were participants in the California WIC program. Client Satisfaction Surveys were completed by 2138 participants, and the focus groups included 29 participants. Results from both phases of the study indicated that client satisfaction with the nutrition education component of the California WIC program was high. Between 80% and 95% of participants responded positively to five satisfaction questions, and focus group participants unanimously agreed that the nutrition education was an essential component of the program. Hispanic participants were more likely than non-Hispanic Caucasians, Asians, or African Americans to respond positively to three of the five satisfaction questions. For two of the questions, the frequency of positive responses increased as age increased and decreased as education level increased. A small segment of clients reported some dissatisfaction by responding negatively to one or more of the satisfaction questions (4% to 20% of respondents). Some suggestions for improvement were made by survey respondents. Identification of some WIC participants who are not completely satisfied with the nutrition education that they have received, paired with differences in satisfaction across demographic variables, suggests the need for a personalized approach to WIC nutrition education.

Labetalol in essential hypertension.

Labetalol is an orally active adrenoreceptor-blocking drug which is a competitive antagonist of both alpha- and beta-adrenoreceptor sites. Thirty patients with essential hypertension were admitted to the study. The mean of initial systolic and diastolic blood pressures of these patients was 160/101 +/- 3/1 supine and 155/104 +/- 3/1 mm Hg standing, and the mean blood pressures at the end of the 16 week trial was 142/90 +/- 4/2 supine and 131/91 +/- 3/2 mm Hg standing. The average dose of labetalol was 546 mg: eight patients received a dose of 300 mg, seven a dose of 600 mg, six a dose f 900 mg, and two a dose of 1,200 mg. The patients who needed the highest doses of labetalol had an initial lowering of their blood pressures followed by a gradual increase despite the higher doses of labetalol. There was no significant change in the mean peripheral renin activity value. Side effects were reported by 18 of the 30 patients, but only 1 patient withdrew for this reason. Two patients were considered to be treatment failures. Overall, labetalol was found to be an effective antihypertensive agent in 15 patients.

Vitamin-mineral supplementation and use of herbal preparations among community-living older adults.

Basic information on seniors' use of supplements is lacking. In this study, a convenience sample of community-living older adults (n = 128) was recruited from 10 sites to determine the prevalence, frequency, duration and type of supplement use. Use information, demographics and medical/nutritional history were collected with an interview-administered questionnaire. Supplement use included both vitamin-mineral and/or herbal preparations. Average age of participants was 76 years and 73% were female. Users comprised 79.9% of the sample. Vitamin E was the most common vitamin-mineral and herbal teas were the most popular herbal preparations. The predominant reason for use was to "improve one's health". Initial results suggest that older adults are learning about, using and purchasing these supplements from a variety of sources. With this common use and the concerns over interactions with prescription medications, further work is required to determine if these findings are consistent in a more diverse, randomly selected older Canadian population.
