Dry mouth and dietary quality in older adults in north Carolina.

OBJECTIVES: To quantify prevalence of dry mouth, association between dry mouth and beverage intake and dietary quality, and association between dry mouth and self-reported dietary accommodations to oral health deficits. DESIGN: Cross-sectional study; data from self-reports. SETTING: Rural North Carolina counties with substantial African-American and American Indian populations. PARTICIPANTS: Six hundred twenty-two participants aged 60 and older. MEASUREMENTS: Data included the 11-item Xerostomia Inventory (higher scores connote greater effect from dry mouth), a food frequency questionnaire (converted into Health Eating Index-2005 scores), and survey items on foods modified before consumption or avoided because of oral health problems. RESULTS: Dry mouth was associated with being female, lower education, and income below the poverty level. Although overall beverage consumption did not vary with dry mouth, consumption of certain sugar-sweetened beverages was positively associated with dry mouth. Overall dietary quality did not differ with dry mouth, but more-severe dry mouth was associated with lower intake of whole grains and higher intakes of fruits. Dry mouth was strongly associated with self-reported modification and avoidance of foods. Those in the highest tertile of dry mouth were more likely to modify several foods than those in the lowest tertile and were more likely to avoid three or more foods. CONCLUSION: Older adults appear to modify foods or selectively avoid foods in response to perceived dry mouth. Despite these behaviors, dry mouth does not result in poorer dietary quality.

Impact of denture usage patterns on dietary quality and food avoidance among older adults.

This study categorizes older adults living in rural areas by denture status, assesses the frequency of wearing dentures during meals, and determines whether denture status or use is associated with dietary quality or the number of foods avoided. A multi-ethnic population-based sample of adults ≥60 years (N = 635) in the rural United States was interviewed. Survey included denture use, removing dentures before eating, and foods avoided due to oral health problems. Dietary intakes were converted into Healthy Eating Index-2005 scores. Sixty percent wore removable dentures of some type; 55% never, 27% sometimes, and 18% always removed dentures when eating. More frequent removal was associated with lower dietary quality and more foods avoided. Those with severe tooth loss had the lowest dietary quality and avoided the most foods. Many rural older adults wear dentures. Learning how they adapt to denture use will offer insight into their nutritional self-management and help explain differences in dietary quality.

Association between dietary quality of rural older adults and self-reported food avoidance and food modification due to oral health problems.

OBJECTIVES: To quantify the association between food avoidance and modification due to oral health problems, to examine the association between food practices and dietary quality, and to determine foods associated with these self-management behaviors. DESIGN: Cross-sectional. SETTING: Rural North Carolina. PARTICIPANTS: Six hundred thirty-five community-dwelling adults aged 60 and older. MEASUREMENTS: Demographic and food frequency data and oral health assessments were obtained during home visits. Avoidance (0, 1-2 foods, 3-14 foods) and modification (0-3 foods, 4-5 foods) due to oral health problems were assessed for foods representing oral health challenges. Food frequency data were converted into Healthy Eating Index-2005 (HEI-2005) scores. Linear regression models tested the significance of associations between HEI-2005 measures and food avoidance and modification. RESULTS: Thirty-five percent of participants avoided three to 14 foods, and 28% modified four to five foods. After adjusting for age, sex, ethnicity, poverty, education, and tooth loss, total HEI-2005 score was lower (P<.001) for persons avoiding more foods and higher for persons modifying more foods (P<.001). Those avoiding three to 14 foods consumed more saturated fat and energy from solid fat and added sugar and less nonhydrogenated fat than those avoiding fewer than three foods. Those who modified four to five foods consumed less saturated fat and solid fat and added sugar but more total grains than those modifying fewer than four foods. CONCLUSION: Food avoidance and modification due to oral health problems are associated with significant differences in dietary quality. Approaches to minimize food avoidance and promote food modification by persons having eating difficulties due to oral health conditions are needed.

Severe tooth loss in older adults as a key indicator of compromised dietary quality.

OBJECTIVE: Poor oral health influences the dietary quality of older individuals. The objective of the present study was to relate the number of teeth to adherence to the 2005 Dietary Guidelines for Americans among an ethnically diverse sample of older adults. DESIGN: A block cluster design was used to obtain a sample of older adults. Data were weighted to census data for ethnicity and gender. Dietary intakes were assessed using an FFQ and converted into Healthy Eating Index-2005 (HEI-2005) scores. SETTING: Two counties in North Carolina, USA, with large African-American and American Indian populations. SUBJECTS: Community-dwelling older adults (N 635). RESULTS: Three hundred and twenty-six participants had severe tooth loss (0-10 teeth remaining), compared with 305 participants with 11+ teeth. After controlling for socio-economic factors, those with 0-10 teeth had lower total HEI-2005 scores and consumed less Total Fruit, Meat and Beans, and Oils, and more energy from Solid Fat, Alcohol and Added Sugar, compared with those with 11+ teeth. Less than 1 % of those with 0-10 teeth and 4 % of those with 11+ teeth met overall HEI-2005 recommendations. Those with 0-10 teeth were less likely to eat recommended amounts of Total Vegetables, Dark Green and Orange Vegetables, and energy from Solid Fat, Alcohol and Added Sugar. CONCLUSIONS: Older adults with severe tooth loss are less likely than those with moderate to low tooth loss to meet current dietary recommendations. Nutrition interventions for older adults should take oral health status into consideration and include strategies that specifically address this as a barrier to healthful eating.

Food avoidance and food modification practices of older rural adults: association with oral health status and implications for service provision.

PURPOSE: Dietary variation is important for health maintenance and disease prevention among older adults. However, oral health deficits impair ability to bite and chew foods. This study examines the association between oral health and foods avoided or modified in a multiethnic rural population of older adults. It considers implications for nutrition and medical service provision to this population. DESIGN AND METHODS: In-home interviews and oral examinations were conducted with 635 adults in rural North Carolina counties with substantial African American and American Indian populations. Avoidance and modification data were obtained for foods representing different dental challenges and dietary contributions. Data were weighted to census data for ethnicity and sex. Bivariate analyses of oral health measures and foods avoided used chi-square and logistic regression tests. Multivariable analyses used proportional odds or nominal regression models. RESULTS: Whole fruits and raw vegetables were the most commonly avoided foods; substantial proportions of older adults also avoided meats, cooked vegetables, and other foods. Food avoidance was significantly associated with self-rated oral health, periodontal disease, bleeding gums, dry mouth, having dentures, and having fewer anterior and posterior occlusal contacts. Associations persisted when controlling for demographic and socioeconomic status indicators. From 24% to 68% of participants reported modifying specific fruits, vegetables, and meats. Modifying harder foods was related to location of teeth and periodontal disease and softer foods to oral pain and dry mouth. IMPLICATIONS: Food services for older adults should consider their oral health status. Policy changes are needed to provide oral health care in benefits for older adults.

The diet quality of rural older adults in the South as measured by healthy eating index-2005 varies by ethnicity.

The 2005 Dietary Guidelines for Americans publication placed increased emphasis on the importance of consuming a wide range of healthful foods and further reducing the consumption of less healthful ones. These recommendations are challenging for rural elders whose functional limitations, fewer resources, and limited access to foods negatively affect the quality of their diets. The purpose of this study was to characterize the diet quality of a multiethnic population-based sample of older adults (N=635) in the southern United States. Data were collected via home visit; dietary intakes were assessed using a food frequency questionnaire and converted into Healthy Eating Index-2005 (HEI-2005) scores used to monitor adherence to dietary guidelines. The mean total HEI-2005 score was 61.9/100 with fewer than 2% meeting the recommended score of 80/100. After controlling for age, sex, marital status, poverty status, and education, African Americans (n=136) had higher total HEI-2005 scores compared to American Indians (n=195) and non-Hispanic whites (n=304) (64.5 vs 60.1 and 61.1 respectively, P=0.001). Certain HEI-2005 foods were consumed in greater amounts by particular groups, such as total fruit and meat and beans (African Americans), whole fruit and grains (African Americans and American Indians), milk (non-Hispanic whites), and energy from solid fat, alcohol, and added sugars (American Indians). The overall diet quality of these rural elders was not adequate as determined by the HEI-2005; however, intakes of dark green and orange vegetables were adequate, and many participants were in compliance with the added fat and sugar guidelines. Determination of factors that promote or prevent the consumption of healthful foods among rural elders may help tailor nutrition education programs for these vulnerable communities.

Disparities in oral health status between older adults in a multiethnic rural community: the rural nutrition and oral health study.

OBJECTIVES: To compare oral health status according to ethnicity and socioeconomic status in African-American, American-Indian, and white dentate and edentulous community-dwelling older adults. DESIGN: Cross-sectional study; data from self-reports and oral examinations. PARTICIPANTS: A multistage cluster sampling design was used to recruit 635 participants aged 60 and older from rural North Carolina counties with substantial African-American and American-Indian populations. MEASUREMENTS: Participants completed in-home interviews and oral examinations. Self-reported data included sociodemographic indicators; self-rated oral health status; presence or absence of periodontal disease, bleeding gums, oral pain, dry mouth; and fit of prostheses. Oral examination data included number of teeth and numbers of anterior and posterior functional occlusal units. RESULTS: African Americans and American Indians had significantly lower incomes and educational attainment than whites. Self-rated oral health was significantly better in whites than in African Americans and American Indians. Prevalence of self-reported periodontal disease and bleeding gums was lower in whites. Of dentate participants, African Americans were significantly more likely than whites to have 11 to 20 teeth and one or two posterior occlusal contacts. Oral health deficits remained associated with ethnicity when adjusted for socioeconomic variables. CONCLUSION: Oral health disparities in older adults in a multiethnic rural area were largely associated with ethnicity and not socioeconomic status. Clinicians should be aware of these health disparities in oral health status and their possible role in disparities in chronic disease. Further research is necessary to understand whether these oral health disparities reflect current or lifetime access to care, diet, or attitudes toward oral health care.

Oral health self-care behaviors of rural older adults.

OBJECTIVES: This analysis describes the dental self-care behaviors used by a multiethnic sample of older adults and delineates the associations of self-care behaviors with personal characteristics and oral health problems. METHODS: A cross-sectional comprehensive oral health survey conducted with a random, multiethnic (African-American, American Indian, white) sample of 635 community-dwelling rural adults aged 60 years and older was completed in two rural southern counties. RESULTS: Rural older adults engage in a variety of self-care behaviors, including the use of over-the-counter (OTC) medicine (12.1 percent), OTC dental products (84.0 percent), salt (50.9 percent), prayer (6.1 percent), and complementary therapies (18.2 percent). Some gender and ethnic class differences are apparent, with greater use by women of OTC medicine and salt and greater use by African-Americans and American Indians of OTC medicine and OTC dental products. The use of dental self-care behaviors appears to be driven by need. Those reporting oral pain, bleeding gums, and dry mouth have greater odds of engaging in most of the dental self-care behaviors, including the use of complementary therapies. CONCLUSIONS: The major factor leading to the use of self-care behaviors is need. Although oral pain does increase the use of self-care behaviors, so do bleeding gums and dry mouth. Research and practice should address self-care behaviors used for oral health problems in addition to pain. Investigators should expand analysis of dental self-care behavior and the relationship of self-care behavior to the use of professional services. Further research also should explore the use of complementary therapies in dental self-care.

Use of tobacco products among rural older adults: prevalence of ever use and cumulative lifetime use.

Tobacco use is a well-documented contributor to morbidity and mortality in the US and worldwide. Information on the comprehensive use of tobacco products is lacking, particularly smokeless tobacco in its various forms. Data from 635 older (>/=60 years) African American, American Indian and White adults in rural North Carolina were analyzed to assess current and lifetime use of cigarettes, cigars, pipe, snuff and chewing tobacco. Participants were classified as being current, former or never users of each product. Lifetime use of each product was determined by asking about typical intensity of use per day and length of time the product has been used. About 70% of participants were current or former users of any tobacco product, and about one-third of participants currently used at least one product. Variations in use were observed by ethnicity and sex, particularly for cigarettes, snuff and chewing tobacco. Variations were also seen according to other demographic and health characteristics. These data add to a limited body of literature on lifetime use of smoked and smokeless tobacco products, and are useful in identifying the impact of these products on morbidity and mortality, particularly for vulnerable populations.
