Abstract:
To investigate ten year trends in folate status in Taiwanese aged >=19 yrs by three Nutrition and Health Survey in Taiwan (NAHSIT) in 1993-1996, 1999-2000 and 2005-2008. Women had higher blood folate levels than men in all three surveys. The prevalence of folate deficiency (5.2% <3 ng/mL) and insufficiency (34.1% <=6 ng/mL) in men was highest in 2005-2008. Adults aged 19-30 yrs had the lowest blood levels and the highest prevalence of deficiency (8.1% in men; 3.5% in women) and insufficiency (48.6% in men; 25% in women) as compared to other age groups in 2005-2008. Folate insufficiency rate in those aged 31-44 yrs was twice as high in men and three times as high in women in 2005-2008 compared to 1993-1996. In the elderly, folate insufficiency rate (28%) in 2005-2008 was not higher than that of 1993-1996, although it was higher than that found in 1999-2000 (18.4%). Men aged >=80 yrs had the poorest folate status in 2005-2008, and men were twice as likely to have inadequate status as women. Plasma homocysteine (Hcy) levels were higher in older men than older women in both surveys. The elderly had significantly higher plasma tHcy in 2005-2008 compared to the 1999-2000 survey. Dark green vegetables and fruit intake frequency in young adults (19-30 yrs) was the lowest among all age groups. This study suggests that folate status in Taiwan has not improved during the past fifteen years, and has worsened in the young population.Cite
Objectives: This study aimed 1) to examine the trends in the prevalence of anemia of the Japanese elderly population and 2) to evaluate the association between hemoglobin concentrations and diet and lifestyle factors, by using data from a population-based, nationwide cross-sectional survey in Japan, from 2003-2009.
Design: A cross-sectional nationally representative survey.
Setting: Japan.
Participants: A nationally representative sample of 10,606 community dwelling men (n=4656) and women (n=5950) aged 65 years and over.
Measurements: Information on anthropometry, dietary intake status, information on current medication, lifestyle habits, and blood biomarker measurements were obtained from the participants. Anemia was defined as hemoglobin concentrations <130 g/L in men and <120 g/L in women. Logistic regression analysis adjusted for subject age was applied to estimate the effect of survey year to anemia prevalence. Multiple regression analysis was applied to estimate the effect of survey year and clinical, dietary and lifestyle factors to hemoglobin values.
Results: Anemia prevalence was 19.3% in men and 21.7% in women. When adjusted for age, the prevalence of anemia significantly decreased by each survey year in both men (odds ratio: 0.933, 95% confidence interval: 0.899, 0.968, p<0.001) and women (odds ratio: 0.968, 95% confidence interval: 0.939, 0.999, p=0.040). The multivariate model explained 25% and 22% of the variance in hemoglobin values in men and women, respectively. In both men and women, each unit of increase in BMI, daily smoking, serum ferritin and albumin was positively associated to hemoglobin values, and age was negatively associated. After adjusting for all factors, hemoglobin values were estimated to increase 0.66 g/L per year in men, and 0.68 g/L per year in women.
Conclusion: Nutritional status of the Japanese elderly as observed by anemia prevalence and hemoglobin concentrations has improved in recent years.

To investigate the association of dietary patterns and dietary diversity with cardiometabolic disease risk factors among South Asians.In a population based study conducted in 2010-11, we recruited 16,287 adults aged >20 years residing in Delhi, Chennai, and Karachi. Diet was assessed using an interviewer-administered 26-item food frequency questionnaire. Principal component analysis identified three dietary patterns: Prudent, Indian, and Non-Vegetarian. We also computed a dietary diversity score. Multinomial and binary logistic regressions were used to calculate adjusted prevalence (95% confidence intervals) of cardio-metabolic disease risk factors across quartiles of dietary pattern and dietary diversity scores.The adjusted prevalence of diagnosed diabetes was lower among participants in the highest versus lowest quartile of the Prudent Pattern (4.7% [3.8-5.6] versus 10.3% [8.5-12.0]), and the Indian Pattern (4.8% [3.7-5.9] versus 8.7% [6.7-10.6] in highest versus lowest quartile, respectively). Participants following the Indian Pattern also had lower adjusted prevalence of diagnosed hypertension (7.0% [5.4-8.5] versus 10.6% [8.6-12.5] in highest versus lowest quartile, respectively). Participants in the highest versus lowest quartile of the dietary diversity score had a lower adjusted prevalence of diagnosed diabetes (4.1% [3.0-5.2] versus 8.2% [7.1-9.3]), diagnosed hypertension (6.7% [5.3-8.1] versus 10.3% [9.1-11.5]), and undiagnosed hypertension (14.2% [12.0-16.4] versus 18.5% [16.9-20.1]).High dietary diversity appears to be protective against cardio-metabolic disease risk factors in this urban cohort of South Asian adults. Further investigation to understand the underlying mechanism of this observation is warranted.

The objective of the paper is to assess the diet and nutritional status of the tribal elderly (> or = 60 years) using data from a cross-sectional study carried out by National Nutrition Monitoring Bureau (NNMB) exclusively in Integrated Tribal Development Project (ITDP) villages of 9 provincial States in India during 1998-1999. A total of 1,239 elderly completed the diet survey (24-hour recall) and 3,932 elderly completed anthropometric measurements. In general, the mean consumption of all the foods and the median intakes of all the nutrients were below the Recommended Dietary Intakes (RDI) in both men and women. The mean heights and weights significantly decreased with increase in age in both males and females (p < 0.001). The prevalence of Chronic Energy Deficiency (CED = BMI < 18.5) was relatively higher (65.4%) in females compared with their male counterparts (61.8%). The prevalence of CED was significantly higher (p < 0.001) among the elderly living in kutchaand landless households. The tribal elderly are subsisting on inadequate diets, which are reflected in the poor intakes of all the nutrients and higher prevalence of undernutrition. Significantly higher proportion of tribal elderly are undernourished compared with their rural counterparts (p < 0.001).

Abstract Objective: To examine associations of changes in dietary intake with education in young black and white men and women. Design: The Coronary Artery Risk Development in Young Adults (CARDIA) study, a multi-centre population-based prospective study. Dietary intake data at baseline and year 7 were obtained from an extensive nutritionist-administered diet history questionnaire with 700 items developed for CARDIA. Setting: Participants were recruited in 1985–1986 from four sites: Birmingham, Alabama; Chicago, Illinois; Minneapolis, Minnesota; and Oakland, California. Subjects: Participants were from a general community sample of 703 black men (BM), 1006 black women (BW), 963 white men (WM) and 1054 white women (WW) who were aged 18–30 years at baseline. Analyses here include data for baseline (1985–1986) and year 7 (1992–1993). Results: Most changes in dietary intake were observed among those with high education (≥ 12 years) at both examinations. There was a significant decrease in intake of energy from saturated fat and cholesterol and a significant increase in energy from starch for each race-gender group ( P < 0.001). Regardless of education, taste was considered an important influence on food choice. Conclusion: The inverse relationship of education with changes in saturated fat and cholesterol intakes suggests that national public health campaigns may have a greater impact among those with more education.

Objectives: The purpose of this study was to investigate dietary contributors to relationships between sleep and all-cause mortality among elderly men and women using a prospective cohort study. Setting: The representative Nutrition and Health Survey in Taiwan (NAHSIT) for elders during 1999–2000. Subjects: One thousand eight hundred sixty-five individuals aged ≥65 years from NAHSIT (942 men and 923 women). Measures of Outcome: Dietary diversity scores (DDS) were from 24-hour dietary recalls. Participants were examined and fasting blood was taken. Sleep quality was assessed by questionnaire and classified as poor, fair, or good. Death registry linkage was made until December 31, 2008. Results: For women, poor sleepers had significantly lower vegetable and vitamin B-6 intakes compared to good sleepers (p < 0.05). For men, good and fair sleepers had a lower risk of death compared to poor sleepers after adjustment with hazards ratios (HRs) and 95% confidence intervals (CIs) of 0.60 (0.42–0.87) and 0.55 (0.36–0.86). The joint HRs for "DDS > 4 and good sleep" were 0.38 (0.22–0.66) for men and 0.52 (0.30–0.88) for women compared to "DDS ≤ 4 and poor sleep." The joint HRs for "plasma pyridoxal phosphate (PLP) adequate and fair sleep" were 0.27 (0.11–0.65) and 0.49 (0.23–1.07) compared to "insufficient and poor sleep" for men and women; for women, PLP adequacy provided significantly reduced HRs for good and poor sleep. Conclusions: Sleep quality played a more important role in mortality for men than for women. Sufficient dietary diversity in men could offset the adverse effect on mortality of poor sleep. In women, PLP predicts mortality more than sleep does.

The Third Report of the National Cholesterol Education Program Expert Panel on Detection, Evaluation, and Treatment of High Blood Cholesterol in Adults (ATP III) highlights the importance of treating patients with the metabolic syndrome to prevent cardiovascular disease. Limited information is available about the prevalence of the metabolic syndrome in the United States, however.To estimate the prevalence of the metabolic syndrome in the United States as defined by the ATP III report.Analysis of data on 8814 men and women aged 20 years or older from the Third National Health and Nutrition Examination Survey (1988-1994), a cross-sectional health survey of a nationally representative sample of the noninstitutionalized civilian US population.Prevalence of the metabolic syndrome as defined by ATP III (>/=3 of the following abnormalities): waist circumference greater than 102 cm in men and 88 cm in women; serum triglycerides level of at least 150 mg/dL (1.69 mmol/L); high-density lipoprotein cholesterol level of less than 40 mg/dL (1.04 mmol/L) in men and 50 mg/dL (1.29 mmol/L) in women; blood pressure of at least 130/85 mm Hg; or serum glucose level of at least 110 mg/dL (6.1 mmol/L).The unadjusted and age-adjusted prevalences of the metabolic syndrome were 21.8% and 23.7%, respectively. The prevalence increased from 6.7% among participants aged 20 through 29 years to 43.5% and 42.0% for participants aged 60 through 69 years and aged at least 70 years, respectively. Mexican Americans had the highest age-adjusted prevalence of the metabolic syndrome (31.9%). The age-adjusted prevalence was similar for men (24.0%) and women (23.4%). However, among African Americans, women had about a 57% higher prevalence than men did and among Mexican Americans, women had about a 26% higher prevalence than men did. Using 2000 census data, about 47 million US residents have the metabolic syndrome.These results from a representative sample of US adults show that the metabolic syndrome is highly prevalent. The large numbers of US residents with the metabolic syndrome may have important implications for the health care sector.

OBJECTIVE: To determine the prevalence of diabetes and examine its association with food intake, anthropometric and metabolic variables, and other coronary risk factors in urban and rural older Mexican populations. DESIGN: A cross‐sectional study. SETTING: Three Mexican communities (urban areas of medium and low income and a rural area). PARTICIPANTS: A total of 121 men and 223 women aged 60 years and older and 93 men and 180 women aged 35 to 59 years were selected randomly for inclusion in the survey, which was derived from the CRONOS study (Cross‐Cultural Research on Nutrition in the Older Adult Study Group) promoted by the European Economic Community. MEASUREMENTS: A personal interview assessed demographic information, personal medical history, and functional status, and a 24‐hour diet recall was obtained. A physical examination included anthropometric and blood pressure measurements. A fasting blood sample was obtained for measurements of lipids, insulin, and glucose. RESULTS: Diabetes prevalence was higher in men than in women for all age groups: 16.7% versus 9.5% in younger adults and 30.8% versus 22.8% in older adults. For all age groups, diabetes was more highly prevalent in urban communities. Using a multivariate stepwise logistic regression, variables associated independently with diabetes in older individuals were: gender (male sex: OR = 2.1; P < .009); diminished carbohydrate intake in the diet (OR = 0.77; P < < .03); central distribution of adiposity (OR = 1.9; P < .03); and functional disability (OR = 2.3; P < .01). This relationship was not observed with living area, income, education, fiber and alcohol intake, body mass index, or age. Individuals 80 years and older had a diminished atherogenic risk profile. Diabetes in older people was associated significantly with hypertriglyceridemia, impaired functional status, and an increased prevalence of ischemic heart disease; in younger adults diabetes was associated with low density lipoprotein (LDL) hypercholesterolemia, hypertriglyceridemia, and a proportionally higher fat intake. CONCLUSION: This survey confirms the high prevalence of diabetes in the older Mexican population — particularly in men and in individuals living in urban areas — associated with an increased prevalence of other coronary risk factors. Diabetes was associated with higher fat, low carbohydrate, low fiber diets and increased prevalence of central distribution of adiposity. In the older subjects, diabetes was associated significantly with hypertriglyceridemia, impaired functional status, and increased prevalence of ischemic heart disease. A bias produced by early mortality and a survivorship effect must be considered in studies of older individuals. The health situation in the older Mexican population presents a complex problem that needs correct diagnosis and better strategies to benefit those segments of the population at increased risk.
