Perceived environmental supports for fruit and vegetable consumption among older adults in the US.

BACKGROUND: The physical and social environments surrounding food, whether perceived or observed, can influence consumers' food choices by changing food access, and affordability, or by changing settings where food-related behaviors occur. AIM: To describe older adults' perceived food environment, identify the most important sites and factors that enable healthy eating, and explore older adults' recommendations for communities to facilitate fruit and vegetable consumption. METHODS: Participants aged 60 and older from metropolitan areas in Massachusetts, Iowa, and Illinois completed a researcher-administered survey to rate the perceived environment including accessibility, availability, and affordability of fruits and vegetables, and perceived importance of factors and establishments related to fruit and vegetable consumption. Participants also suggested changes for establishments to facilitate fruit and vegetable consumption. RESULTS: The majority of the 142 participants perceived their food environment for fruits and vegetables as not difficult to access (85.2%) with good or excellent availability (90.1%). Education, marital status, and race were associated with some aspects of the perceived food environment. Perceived accessibility and supermarkets were rated as the most important factor and establishment, respectively, to facilitate fruit and vegetable consumption across all study sites. Participants proposed recommendations to address the availability, quality, accessibility and affordability of fruits and vegetables. CONCLUSION: Interventions promoting accessible, affordable, quality fruits and vegetables may improve older adult consumers' perceptions of their food environment. Communities may also use undervalued resources such as mobile markets more strategically to provide additional support for healthy eating in older adults.

Questionnaire on Irritable Bowel Syndrome and Symptom Management Among Endurance Athletes Is Valid and Reliable.

BACKGROUND: Gastrointestinal symptoms are reported in a large proportion of endurance athletes, with similarities in symptom type and distribution to irritable bowel syndrome (IBS). AIMS: The objective of this study was to develop and validate a questionnaire to assess IBS diagnoses or fit to IBS diagnostic criteria in this population along with nutritional habits, gastrointestinal symptoms, and symptom management strategies. METHODS: A 93-item Endurance Athlete Questionnaire was developed to address the objective, targeted at American endurance athletes completing a marathon, ultra-marathon, half-distance triathlon, and/or full-distance triathlon that year. Content validity was established by expert reviewers (n = 6), and face validity was evaluated by endurance athletes (n = 9). Test-retest reliability was assessed by target athletes (n = 51). Participants completed two rounds of the questionnaire, separated by 1-2 weeks. Results were analyzed using Pearson and Spearman correlations and paired comparisons. RESULTS: Slight modifications in wording and three demographic questions were added based on the input of expert and athlete reviews. Pearson correlation coefficient of test-retest total questionnaire scores was significant at 0.839 (P < 0.001). Paired comparison of individual questions found significant differences in 10 of 236 analyzed responses; however, these did not affect fit to IBS diagnostic criteria for those without other GI diseases/disorders. CONCLUSIONS: The Endurance Athlete Questionnaire proved to be a valid and reliable measure of IBS diagnostic criteria, gastrointestinal symptoms, nutritional habits, and symptom management strategies among endurance athletes. Future implementation will help inform gastroenterologists with endurance athlete patients and can elucidate whether certain behaviors could be contributing to athlete gastrointestinal symptoms.

The Relationship Between Intradialytic Nutrition and Gastrointestinal Symptoms Using a Modified Version of the Gastrointestinal Symptom Rating Scale.

OBJECTIVE: Intradialytic nutrition has been shown to improve nutritional status in maintenance hemodialysis (HD) patients but remains controversial due in part to concerns over hemodynamic stability and gastrointestinal (GI) distress. There are limited data on the relationship between intradialytic nutrition and GI symptoms, possibly due to the lack of a validated tool. Therefore, we intended to validate a questionnaire to measure GI symptoms associated with a single HD treatment and determine the relationship between intradialytic nutrition and GI symptoms. DESIGN: Cross-sectional study. Forty-eight maintenance HD patients. MAIN OUTCOME MEASURE: GI symptoms and dietary intake during HD treatment. RESULTS: In general, we found acceptable internal consistency (Cronbach's alpha >0.5, exception reflux domain) and repeatability in all 5 domains of a modified version of the Gastrointestinal Symptom Rating Scale. The prevalence of GI symptoms associated with a single HD treatment (generalized score greater than 1) was 54.2, 43.7, 6.2, 41.7, and 45.8% for the abdominal pain, indigestion, reflux, diarrhea, and constipation domains, respectively. More than two-thirds of patients chose to eat during treatment (168.6 ± 165.6 kcal) with the most commonly consumed items being candy, oral supplements, and cookies. There was no difference in GI symptoms among patients who did or did not eat (P > .05). However, the amount of total dietary fat and fiber consumed during treatment was associated with greater indigestion (P < .05) prior to accounting for outliers or multiple comparisons. CONCLUSION: In this sample, the modified version of the Gastrointestinal Symptom Rating Scale was a generally valid tool for measuring GI symptoms associated with a single HD treatment. Patients who ate during treatment did not experience greater GI symptoms than those who did not; however, high amounts of fat and fiber may be associated with greater GI symptoms. Prospective trials should examine the relationship between GI symptoms and dietary intake during treatment in HD patients.

Influence of seasoning on vegetable selection, liking and intent to purchase.

Low vegetable intake continues to be a health concern, and strategies to increase vegetable intake have resulted in only small increases. One strategy that has received less attention is the use of seasonings. This study's objective was to determine the impact of seasoning on vegetable selection, liking, and intent to purchase. We conducted a 3-week study in a public café on a university campus. Customers buying a main dish could select a vegetable side (seasoned [SS] or steamed [ST]) at no cost. Based on café data and power analysis (alpha 0.05, 80% power), 2 days per vegetable pair were conducted with carrot, broccoli, and green bean pairs randomized 3 days/week 1 and 3, with normal service week 2. Selection was greater for SS vs ST, n = 335 vs. 143 for all 3 vegetables combined; n = 97 vs 47 for carrots; n = 114 vs. 55 for broccoli; n = 124 vs. 41 for green beans (p < 0.001 Chi-Square). Liking responses were similar for SS vs ST and were high for all vegetables. Response distribution was not significantly different for SS vs ST vegetables when people were asked if they would purchase the vegetable that they selected. More customers chose the 'somewhat likely' and 'very likely' (n = 353) than the 'not likely' and 'definitely would not' (n = 121) purchase responses. Regression showed that people who did not often consume a vegetable with lunch while dining out were 1.59 times more likely to select the SS vegetables over the ST (p = 0.007). Given a choice, consumers were more likely to select a seasoned vegetable. With low vegetable consumption as a predictor of seasoned vegetable choice, offering seasoned vegetables may increase intake in those with poor vegetable intake in a café setting.

Nutritional status as assessed by nutrient intakes and biomarkers among women of childbearing age--is the burden of nutrient inadequacies growing in America?

OBJECTIVE: Understanding nutrient intakes among women of childbearing age within the USA is important given the accumulating evidence that maternal body weight gain and nutrient intakes prior to pregnancy may influence the health and well-being of the offspring. The objective of the present study was to evaluate nutritional status in women of childbearing age and to ascertain the influence of ethnicity and income on nutrient intakes. DESIGN: Nutritional status was assessed using data on nutrient intakes through foods and supplements from the National Health and Nutrition Examination Survey. Biomarker data from the Centers for Disease Control and Prevention were used to assess nutritional status for selected nutrients. Poverty-income ratio was used to assess family income. SUBJECTS: White (n 1560), African-American (n 889) and Mexican-American (n 761) women aged 19-30 and 31-50 years were included. SETTING: A nationally representative sample of non-pregnant women of childbearing age resident in the USA. RESULTS: African-American women had the lowest intakes of fibre, folate, riboflavin, P, K, Ca and Mg. Women (31-50 years) with a poverty-income ratio of ≤ 1.85 had significantly lower intakes of almost all nutrients analysed. Irrespective of ethnicity and income, a significant percentage of women were not consuming the estimated recommended amounts (Estimated Average Requirement) of several key nutrients: vitamin A (~80%), vitamin D (~78%) and fibre (~92%). Nutrient biomarker data were generally reflective of nutrient intake patterns among the different ethnic groups. CONCLUSIONS: Women of childbearing age in the USA are not meeting nutrient intake guidelines, with differences between ethnic groups and socio-economic strata. These factors should be considered when establishing nutrition science advocacy and policy.

The HOT (Healthy Outcome for Teens) project. Using a web-based medium to influence attitude, subjective norm, perceived behavioral control and intention for obesity and type 2 diabetes prevention.

We hypothesized that Theory of Planned Behavior (TPB) constructs (behavioral belief, attitude, subjective norm, perceived behavioral control, knowledge and behavioral intention) regarding preventive behaviors for obesity and type 2 diabetes will change favorably after completing the web-based intervention, HOT (Healthy Outcome for Teens) project, grounded in the TPB; and that passive online learning (POL) group will improve more than the active online learning (AOL) group. The secondary hypothesis was to determine to what extent constructs of the TPB predict intentions. 216 adolescents were recruited, 127 randomly allocated to the treatment group (AOL) and 89 to the control group (POL). The subjects completed a TPB questionnaire pre and post intervention. Both POL and AOL groups showed significant improvements from pretest to posttest survey. However, the results indicated no significant difference between POL and AOL for all constructs except behavioral belief. Correlational analysis indicated that all TPB constructs were significantly correlated with intentions for pretest and posttest for both groups. Attitude and behavioral control showed strongest correlations. Regression analysis indicated that TPB constructs were predictive of intentions and the predictive power improved post intervention. Behavioral control consistently predicted intentions for all categories and was the strongest predictor for pretest scores. For posttest scores, knowledge and attitude were the strongest predictors for POL and AOL groups respectively. Thus, HOT project improved knowledge and the TPB constructs scores for targeted behaviors, healthy eating and physical activity, for prevention of obesity and type 2 diabetes.

Metabolic and nutritional profile differences among Mexican, Mexican-American and Non-Hispanic White children.

OBJECTIVE: To compare somatometric variables, lipid profile, diet, and physical activity between Mexican children living in México (MEX), and Mexican-American (MXA) and Non-Hispanic White (NHW) children from the United States (US) to examine the possible influence of ethnicity and residency on these factors. MATERIAL AND METHODS: Six to twelve years old children data from a study from central México and the US National Health and Nutrition Examination Survey was compared. Data were categorized to examine the effect of residency (MEX vs. MXA and NHW) and ethnicity (MEX vs. MXA and NHW) on the variables of interest. RESULTS: Living in the US was associated with higher cholesterol levels in younger boys and older girls (p < 0.05), and high saturated fat intake in all groups (p < 0.0001). Living in México increased the likelihood of abnormal HDL (p < 0.001), systolic (p < 0.001), and diastolic blood pressure (p < 0.0001). Caucasian young girls were more likely to have high cholesterol intake (p < 0.02) than their Mexican counterparts. CONCLUSIONS: These findings suggest that residency is linked to impaired lipid profile and blood pressure in children, whereas ethnicity seems to have an impact on dietary choices.

Establishing content validity for the Nutrition Literacy Assessment Instrument.

INTRODUCTION: Identification of low levels of health literacy is important for effective communication between providers and clients. Assessment instruments for general health literacy are inadequate for use in nutrition education encounters because they do not identify nutrition literacy. The primary objective of this 2-part study was to assess content validity for the Nutrition Literacy Assessment Instrument (NLAI). METHODS: This study included a 35-item online survey of registered dietitians (134 of whom answered all questions) and a pilot study in which 5 registered dietitians used the NLAI among 26 clients during nutrition education consultations. To assess agreement with the NLAI by survey participants, we used the following scale: "necessary" (70% agreement), "adequate" (80% agreement), or "good" (90% agreement); comments were analyzed by using content analysis. For the pilot, we made comparisons between subjective assessments, the Rapid Estimate of Adult Literacy in Medicine (REALM), and the NLAI. Registered dietitians also completed a postpilot-study survey. RESULTS: For the online survey, we found good agreement (average, 89.7%) for including each section of the NLAI. All sections accomplished their purpose (average, 81.5%). For the pilot, REALM and NLAI correlation (r = 0.38) was not significant; the subjective assessment of clients by dietitians and NLAI lacked agreement 44% of the time, and registered dietitians provided instruction on deficient knowledge and skills identified by the NLAI 90% of the time. CONCLUSION: The NLAI is a content-valid measure of nutrition literacy. Additional validation of the NLAI is important because an objective instrument is needed for identifying nutrition literacy, a construct that appears to be different from health literacy.

Development, relative validity, and reliability of a food frequency questionnaire for a case-control study on dietary advanced glycation end products and diabetes complications.

Dietary advanced glycation end products (dAGEs) could be involved on diabetes complications, yet their quantification is not standardized. The objective of this study was to design a food frequency questionnaire (FFQ) for dAGEs, and to assess its reliability and validity. For the design, data from 30 subjects was used. The final instrument had 90 food items. To measure reliability and validity, 20 participants with type 2 diabetes filled out twice the FFQ (FFQ-T1, FFQ-T2) and 7-day food records (7-dFR). The Shrout-Fleiss coefficient was 0.98 showing good reliability. For validation, the results for the weighted kappa were 0.55 (moderate agreement) for FFQ-T1 and 0.64 (good agreement) for FFQ-T2, and 75% and 80% of subjects respectively were correctly classified into tertiles; Bland-Altman graphics showed no systematic bias. This FFQ is comparable to 7-dFR for measuring dAGEs. To our knowledge, this is the first questionnaire designed to measure specifically dAGEs.

The relationship between dietary advanced glycation end products and indicators of diabetes severity in Mexicans and non-Hispanic whites: a pilot study.

Diet is an important source of exogenous advanced glycation end products (AGEs). Dietary AGEs content depends on nutrient composition and on the way food is processed/cooked. The objective of our study was to compare AGEs intake of two different ethnic groups (Mexicans and non-Hispanic whites) with type 2 diabetes mellitus (DM) and to study the relationship between dietary AGEs and diabetes-related complications. Complications were self-reported by subjects (n = 65) and categorized according to a published DM disease severity index as low risk or moderate-high risk. Dietary records for 10 days were used to estimate dietary AGEs from a published food table. Non-Hispanic whites had higher intake of dietary AGEs (natural logarithm was used, LogAGEs) when compared with Mexicans, which was consistent with their higher intake of saturated fat. In addition, for each unit increase in the LogAGEs, a participant was 3.7 times more likely to have moderate-high risk for cardiovascular disease.

Call for Cultural and Language-Concordant Diabetes Care, Nutrition Education, and Self-Management for South Asian Individuals Living in the US.

Ethnic South Asian Americans have the highest relative risk of type 2 diabetes mellitus in the US. Culturally tailored and language-concordant diabetes care and nutrition interventions can potentially promote South Asian diabetes management and disease progression. From our perspective, the extent of their use and evaluation in the US settings remains limited. This Perspective characterizes and evaluates the necessity and outcomes of culturally and linguistically adapted lifestyle interventions targeted toward type 2 diabetes mellitus indicators among South Asian individuals in the US. Suggestions for how this education could be modified include emphasizing the cultural and linguistic knowledge and self-awareness of diabetes educators and the sociological and historical factors that influence the cultural and linguistic orientation of diabetes care professionals and their clients. Such strategies could ensure better diabetes education and self-management among South Asian individuals.

Perceived Facilitators and Barriers to Implementing Culturally Inclusive Diets into Hospitals and Long-Term Care Facilities.

OBJECTIVES: To identify perceived facilitators and barriers to implementing culturally inclusive foods into hospitals and long-term care (LTC) from the perspectives of registered dietitians and food service directors. DESIGN: Cross-sectional survey. SETTING AND PARTICIPANTS: Online nationwide survey of registered dietitians and food service directors working in hospitals or LTC. METHODS: We analyzed and compared participants' perceived barriers to implementing culturally inclusive foods in hospitals and LTC, assessed through a question in which we provided respondents with 13 different barriers and asked them to report the top 3. Then, we conducted a qualitative analysis of perceived facilitators, which respondents described in open-ended comments. RESULTS: The most common perceived barriers to implementing culturally inclusive foods were cost of ingredients (44%) and staff cultural knowledge and competence (44%). LTC respondents perceived barriers including (1) willingness of staff to adopt new practices, (2) time, (3) staff burnout, and (4) local/facility-level regulatory barriers more frequently than hospital respondents. Administrative buy-in, staff diversity, and patient considerations (eg, feedback and demand) were perceived facilitators to implementing culturally inclusive foods. CONCLUSIONS AND IMPLICATIONS: Implementing culturally inclusive foods into hospitals and LTC requires administrative buy-in, willingness to change, and resources including staff diversity and cultural knowledge and awareness. Incorporating patient feedback and preferences into decisions related to dietary offerings could further motivate menu modifications. Further examination of organizational and state policies regulating diet, particularly in LTC settings, is necessary to understand both how to implement culturally inclusive foods and further, to inform investigation of health outcomes (physical and mental) associated with increasing culturally inclusive food offerings in these facilities.

Knowledge, attitudes, and beliefs about nutrition and childhood overweight among WIC participants.

This study assessed knowledge, attitudes, and beliefs about nutrition, physical activity, and health risks related to childhood overweight among Women, Infants, and Children participants. Most (n = 165) were knowledgeable about causes/health risks of overweight (90%). The belief that "some people are born big or thin . . . " varied by education level (P < 0.05). Concerning activity, many (white non-Hispanic, 53%; African-American 69%) reported their children spending 2 to 3 hours per day watching television and playing video games, with 10% white non-Hispanic and 21% of African-American reporting 4 hours or more (P < 0.05). Beliefs related to the risk of overweight and activity level of the children differed among ethnic groups.

Hypoglycemia education needs.

Because more than half of those participating in a community-based diabetes session expressed experience with hypoglycemia, we sought additional information by conducting focus groups before developing programs or materials for educational support. The objectives of these focus groups were to determine how and to what extent hypoglycemia affected people, and what, if any, methods were used to prevent or treat the condition, to better target education in the future. Four focus groups were held using a tiered discussion script with a moderator and comoderator. Discussions were audiotaped, transcribed, and analyzed by content by independent researchers. Five themes emerged from the discussions: friends, family, and neighbors need hypoglycemia education as well as individuals themselves; leaving home is a concern if you experience hypoglycemia; overeating occurs when treating hypoglycemia; routine is important; and hypoglycemia is a limitation. We found that hypoglycemia had a significant impact on the participants' quality of life.

Evaluation of Preferences Among Students Participating in the US Department of Agriculture Fresh Fruit and Vegetable Program.

BACKGROUND: Improving children's fruit and vegetable (FV) preferences may be important as preferences can predict FV consumption. The purpose of this study was to evaluate FV preferences over time, with repeated experience, as part of the Fresh Fruit and Vegetable Program (FFVP). METHODS: Fruits (F; N = 28) and vegetables (V; N = 29) were distributed twice a week, over 35 weeks, at a participating FFVP school (N = 236 students, 12 teachers, K-2nd grade). Preference ratings using 3-point Likert scale were analyzed over 35 weeks. RESULTS: For 57 FVs rated for preference, ratings revealed that F had higher frequency of children choosing "I like it" than for V (78% F; 38.2% V; p < .05) and liking distribution was different between F and V (p < .001). Significant relations were found between liking and: (1) grade (r = -0.02, p = .02), and (2) time (r = -0.09, p < .001). Models indicated that V served (ß = -0.40), timepoint (ß = -0.07), and grade level (ß = -0.02) accounted for significant variance for preference ratings (R2  = 0.17, p < .001), indicating that preference ratings declined over time. CONCLUSIONS: Fruits were preferred over vegetables. Overall preference ratings were negatively impacted by time, grade level, and vegetables served. Being exposed one time to a variety of FVs did not improve ratings for vegetables.

Secondary Fracture Prevention: Consensus Clinical Recommendations from a Multistakeholder Coalition.

Osteoporosis-related fractures are undertreated, due in part to misinformation about recommended approaches to patient care and discrepancies among treatment guidelines. To help bridge this gap and improve patient outcomes, the American Society for Bone and Mineral Research assembled a multistakeholder coalition to develop clinical recommendations for the optimal prevention of secondary fracture among people aged 65 years and older with a hip or vertebral fracture. The coalition developed 13 recommendations (7 primary and 6 secondary) strongly supported by the empirical literature. The coalition recommends increased communication with patients regarding fracture risk, mortality and morbidity outcomes, and fracture risk reduction. Risk assessment (including fall history) should occur at regular intervals with referral to physical and/or occupational therapy as appropriate. Oral, intravenous, and subcutaneous pharmacotherapies are efficacious and can reduce risk of future fracture. Patients need education, however, about the benefits and risks of both treatment and not receiving treatment. Oral bisphosphonates alendronate and risedronate are first-line options and are generally well tolerated; otherwise, intravenous zoledronic acid and subcutaneous denosumab can be considered. Anabolic agents are expensive but may be beneficial for selected patients at high risk. Optimal duration of pharmacotherapy is unknown but because the risk for second fractures is highest in the early post-fracture period, prompt treatment is recommended. Adequate dietary or supplemental vitamin D and calcium intake should be assured. Individuals being treated for osteoporosis should be reevaluated for fracture risk routinely, including via patient education about osteoporosis and fractures and monitoring for adverse treatment effects. Patients should be strongly encouraged to avoid tobacco, consume alcohol in moderation at most, and engage in regular exercise and fall prevention strategies. Finally, referral to endocrinologists or other osteoporosis specialists may be warranted for individuals who experience repeated fracture or bone loss and those with complicating comorbidities (eg, hyperparathyroidism, chronic kidney disease). © 2019 American Society for Bone and Mineral Research.

The creation and impact evaluation of "Your guide to diet and diabetes," an interactive web-based diabetes tutorial.

BACKGROUND: Millions of Americans turn to the Internet for health information. A need for a comprehensive website that provides information on diet and diabetes management was identified. Therefore, the goal of this study was to develop an easy-to-use website that provided accurate information about diet and diabetes management in an interactive format that was widely accessible. METHODS: The "Your Guide to Diet and Diabetes" website was developed through issue identification, expert panel review, and face validity phase for content and knowledge/skill assessment surveys. During the first 2 weeks of the website's availability, impact data were collected from website visitors. Responses to demographic questions, knowledge, and skill questions were collected in a database. RESULTS: Of the 406 individuals who completed a demographic question, a maximum of 104 respondents chose to answer one or more of the interactive knowledge or skills questions. CONCLUSIONS: "Your Guide to Diet and Diabetes" filled a need for an easy-to-use website that addressed the issues of diet and diabetes. Based on the number of visits to the login page (n = 6,124) and number of individuals who answered demographic questions, the site was well received. While a smaller group of participants elected to complete the interactive knowledge and skills questions, responses to these questions demonstrated that participants obtained knowledge from the website. In particular, participants increased their knowledge of food sources and appropriate serving sizes of carbohydrate. The "making a plate" skill activity was used with much greater frequency than the more conceptually complex carbohydrate counting skill activity.

Assessing calcium intake in postmenopausal women.

INTRODUCTION: Because foods fortified with calcium are increasingly available, the calcium content of calcium-fortified foods may not be adequately captured in traditional assessments of dietary intake, such as dietary records analyzed with commercially available software. The primary objective of our study was to design and test a calcium-focused food frequency questionnaire (CFFFQ) including foods naturally rich in calcium and calcium-fortified foods. Secondary objectives were to review calcium sources and adequacy of intake in black and in white postmenopausal women. METHODS: We studied a convenience sample of 46 black and 139 white postmenopausal women (mean [SD] age 69.4 [5.8] years). Participants completed a multiple-pass interview for 24-hour recall of foods eaten and the 46-item CFFFQ. RESULTS: The correlation between measures for total daily calcium intake was moderately strong (r = 0.53, P < .001). The CFFFQ estimated greater total daily calcium intake than did the 24-hour recall (mean [SD], 1,021 [624] mg/d vs 800 [433] mg/d, P < .001). As daily calcium intake increased, the 24-hour recall increasingly underreported calcium (r = 0.41, P < .001) compared with the CFFFQ. Cross-tabulation and Chi2 analyses found that the CFFFQ had greater specificity for lower calcium intakes. For calcium classified by food groups, there was moderate correlation for dairy (r = 0.56, P < .001) and fruits (r = 0.43, P < .001). The CFFFQ overestimated mean total calcium compared with the 24-hour recall by 221 mg/d (P < .001), including within racial groups (195 mg/d for black women, P = .04, and 229 mg/d for white women, P < .001). Dairy was the primary calcium source for both groups (55% of intake for black women and 57% of intake for white women). CONCLUSION: The CFFFQ can be used to identify postmenopausal women with inadequate calcium intakes (<800 mg/d) and to identify key sources of dietary calcium. Older black women consume less daily calcium than do older white women.

Effects of age, gender and chronic obstructive pulmonary disease on taste acuity.

PRIMARY OBJECTIVE: Multifactoral interactions of age, gender and medical conditions were investigated because of lack of definitive results in previous studies. METHODS: Absolute detection and recognition were determined thresholds using a three-alternative forced-choice test by younger men (n=50) and women (n=48); and by older men (n=43) and women (n=46) for each of the four basic tastes (sweet, sour, bitter, salty). Data from 46 elderly men with chronic obstructive pulmonary disease (COPD) were included. RESULTS: Age was consistently associated with elevated recognition thresholds for each of the four tastants for men only. Gender differences were seen for absolute sweet thresholds and for sour, bitter, and sweet recognition thresholds for older participants. Men with COPD had the highest levels for absolute and recognition thresholds for each tastant. CONCLUSIONS: Gender plays a role in taste perception. COPD diminishes taste.
