Associations of nationality and race with nutritional status during perimenopause: implications for public health practice.

OBJECTIVE: To examine associations of nationality and race with anthropometry, self-reported nutrient intakes, health history, and socioeconomic status (SES) of perimenopausal (age 40-55 years) Floridians. DESIGN: Interviewer conducted cross-sectional survey. SETTING: South Florida, 2000-2001. PARTICIPANTS: Convenience sample of 109 Black (Caribbean [n=31] and African-American [n=251), and White (n=53) women with intact ovaries and uteri. MAIN OUTCOME MEASURES: Nutrient intakes and anthropometry. RESULTS: Both races had similar mean age, education, SES, reported heavy menses, and physician-diagnosed iron deficiency anemia. Dietary reference intakes (DRIs) were unmet for calcium (67%) and iron (35%) and exceeded for energy (28%). A decade of decreased milk (61%) and red meat (69%) consumption, key micronutrient sources, was reported. Significantly more Blacks exceeded anthropometric recommendations (P=.01); more African Americans exceeded energy DRIs even after controlling for body mass index (P=.006). More Whites exceeded calcium DRIs (P=.04) and reported self-diagnosed depression (P=.001). More Caribbean-born (P<.05) met fat, saturated fat, carbohydrate, and fiber recommendations. CONCLUSION: Reported suboptimal iron and calcium intakes coupled with bone demineralization and heavier menses, characteristic of perimenopause, could heighten osteoporosis and anemia risks. Reports that more Whites were depressed and more Caribbean-born persons met dietary recommendations, even though anthropometrics and BMI-adjusted energy intakes among Blacks exceeded recommendations, have possible public health implications. As more "baby-boomers" reach this age, findings highlight the need for culturally appropriate interventions, eg, nutrition education that emphasizes relationships between nutrient and energy needs and the composition of foods consumed by various ethnicities.

Improvements in nutritional intake and quality of life among frail homebound older adults receiving home-delivered breakfast and lunch.

OBJECTIVE: This study evaluated the influence that expanding a home-delivered meals service to include breakfast and lunch would have on the nutritional status and quality of life of at-risk older adults. DESIGN: This cross-sectional field study compared two groups. The breakfast group (n=167) received a home-delivered breakfast and lunch, 5 days per week. The comparison group (n=214) received a home-delivered lunch 5 days per week. Participants' 24-hour food recall, demographics, malnutrition risk, functional status, and surveys of quality of life as health, loneliness, food enjoyment, food security, and depression were obtained. PARTICIPANTS: Study participants were recruited from five Elderly Nutrition Programs involved in the Morning Meals on Wheels breakfast service demonstration project. They formed a geographically and racially/ethnically diverse sample. Participants ranged in age from 60 to 100 years, were functionally limited, and at high nutritional risk. Most were low income, lived alone, and had difficulty shopping or preparing food. STATISTICAL ANALYSIS: Descriptive statistics were used to assess group comparability. Independent sample t tests were used to examine group differences, with Bonferroni's method used to control for familywise Type I error. RESULTS: Breakfast group participants had greater energy/nutrient intakes (P<.05), greater levels of food security (P<.05), and fewer depressive symptoms (P<.05) than comparison group participants. CONCLUSIONS: The addition of a breakfast service to traditional home-delivered meals services can improve the lives of frail, homebound older adults. Agencies should be encouraged to expand meals programs to include a breakfast service to a targeted population.

Interactive learning for congregate nutrition site nutrition education: a pilot study.

Older adults who participate in the Older Americans Act Title III-C Elderly Nutrition Program often are at moderate to high nutritional risk. Although nutrition education is a component of the Elderly Nutrition Program, there are numerous barriers to promoting behavior change in older adults. Nutrition education programs targeted to congregate nutrition site participants must address their unique nutritional needs, while engaging them in activities that promote learning and motivate them to make positive behavior changes. This paper describes a pilot study of a theory-driven, five-lesson educational module designed to promote healthful eating behaviors among congregate nutrition site participants through interactive learning.

The professional development portfolio process: setting goals for credentialing.

Professional Development Portfolio (PDP), the new credentialing system for dietetics professionals, places the responsibility for learning, professional development, and career direction on the individual practitioner. This study used questionnaires and focus group interviews to determine whether dietitians engage in reflection, self-assessment, and goal setting, the critical components of PDP recertification. Volunteers (n = 132) participated in 16 focus groups held during 8 state dietetic association meetings. Content analysis was conducted. Some subjects reflected using an informal non-structured process (42 text units), almost half (41%) performed annual self-assessments, and 25% set goals. Job availability, new practice areas, family obligations, and employer needs were key factors in goal formulation. Opportunities for self-direction, independent decision-making, and application of technical expertise were also considered in career choices and goal setting. Although few participants were currently performing PDP critical components, we conclude dietetic practitioners can gain the necessary skills for professional development with the newly available PDP Guide to support the portfolio process. We recommend that dietitians (a) allow sufficient time for the reflection process, including the use of additional tools; (b) develop personal mission statements to drive the goal-setting process; and (c) use effectiveness criteria to critique their goals.
