Dose-response relationships regarding vitamin B-6 in elderly people: a nationwide nutritional survey (Dutch Nutritional Surveillance System).

The dietary intake and biochemical status of vitamin B-6 in 476 apparently healthy Dutch elderly people (aged 65-79 y), who were not using drugs known to affect vitamin B-6 metabolism, were evaluated. Intake of vitamin B-6 per gram protein was related to biochemical data, namely plasma pyridoxal 5'-phosphate (PLP) and cofactor stimulation of aspartate aminotransferase in erythrocytes (AST-AC). Based on a cutoff point of 2.02 for AST-AC, approximately 9% of the elderly people not using vitamin B-6 supplements had a marginal vitamin B-6 status. About 7% were using vitamin B-6 supplements. Dietary intake of vitamin B-6 per gram protein was negatively related to AST-AC. Vitamin B-6 intakes per gram protein higher than 0.020 mg were necessary to ensure an AST-AC value less than 2.02. At high PLP values AST-AC hardly varied. The results seem to indicate a higher requirement of vitamin B-6 in elderly people than in younger adults.

Dietary intakes of Canadians in the 1990s using population-weighted data derived from the provincial nutrition surveys.

Provincial nutrition surveys of adults were conducted between 1990 and 1999 in Canada. Eight reports have been issued, and one is forthcoming. The purpose of this study was to estimate the national dietary intake of adult Canadians, using the publicly available data. Group mean-nutrient-intake data from 16 915 adults, aged 18 to 84 years, from published provincial reports were collated by age and sex for each of 9 provinces (Manitoba data were unavailable). Using Canadian census data appropriate to the year of collection, intake data were weighted to provide 1 national intake value for each nutrient, by 8 age and sex categories. In general, the energy and nutrient intake of adults decreased with age. For every age group, with the exception of vitamin C, intake of nutrients by men was greater than that by women. On the basis of a comparison of recently recommended intakes (Dietary Reference Intakes), the nutrients that are of concern because of inadequate intake include dietary fibre, calcium, magnesium, and folate. The data demonstrate the impact of folate fortification on folate intake; the mean intake became twice that of prefortification levels. This study used group mean-intake data; therefore, we cannot make definitive conclusions about the prevalence of inadequacy for the nutrients. Because of limitations with some provincial response rates, our data should not be construed as representative of the Canadian population. However, because these surveys were completed between the 19701972 Nutrition Canada Survey and the 2004 Canadian Community Health Survey, these population-weighted data might be a useful point of comparison for monitoring trends in nutrient intake from food.

Comparison of dietary patterns between population samples in the three French MONICA nutritional surveys.

A nutritional survey was carried out from 1985 to 1987 in three French areas covered by the ischaemic heart disease registers: Bas-Rhin (BR), Haute-Garonne (HG) and the Urban Community of Lille (UCL). 1,128 men aged 45-64 were included in a survey, using the 3-day record method. The results, after adjustment for age, socio-economic status, residence and prescribed diet, showed differences, sometimes significant, between the three samples. Fat represented 37% of the total energy intake in BR, 36% in UCL, and 34% in HG. The P:S ratio ranged from 0.50 in HG, to 0.47 in BR, and 0.40 in UCL. These differences were due to a higher intake of vegetable fat and a lower intake of animal fat in HG. In spite of a very important alcohol intake, with no big differences between the centres (33 to 36 g/day), we noticed that HG drank mainly wine, whereas BR and UCL drank wine and beer in about the same proportions.

The Andalusian Nutritional Survey: comparison of the nutritional status of Andalusian children aged 6-60 months with that of the NCHS/CDC reference population.

Presented are the results of the anthropometric component of the 1985 Andalusian Nutritional Survey. The heights and weights of a representative sample of children aged 6-60 months were compared with data for the National Center for Health Statistics/Centers for Disease Control (NCHS/CDC) reference population. Of the 1181 preschool-age children surveyed, the great majority fell within +/- standard deviation (SD) scores for height-for-age (93.6%) and weight-for-height (93.5%), and most (87.7%) were within +/- 2 SD scores of the mean value for the NCHS/CDC reference population for both height-for-age and weight-for-height. The proportion of stunting was 3.2%, that of wasting 1.0%, and that of both stunting and wasting 0.4%. For both sexes, the distribution of height-for-age was comparable with that of the NCHS/CDC reference population, while that for weight-for-height was skewed to the right. This suggests that for the same height, the weight of Andalusian children increased more over the 5 years preceding the survey than that of the reference population over the period 1971-74. The data obtained could be used as a baseline to evaluate the effectiveness of future nutrition programmes for children who are at a high risk of undernutrition or obesity.

Use of cognitive interview techniques in the development of nutrition surveys and interactive nutrition messages for low-income populations.

The effectiveness of dietary surveys and educational messages is dependent in part on how well the target audience's information processing needs and abilities are addressed. Use of pilot testing is helpful; however, problems with wording and language are often not revealed. Cognitive interview techniques offer 1 approach to assist dietitians in understanding how audiences process information. With this method, respondents are led through a survey or message and asked to paraphrase items; discuss thoughts, feelings, and ideas that come to mind; and suggest alternative wording. As part of a US Department of Agriculture-funded nutrition education project, 23 cognitive interviews were conducted among technical community college students in North Carolina. Interview findings informed the development of tailored computer messages and survey questions. Better understanding of respondents' cognitive processes significantly improved the language and approach used in this intervention. Interview data indicated 4 problem areas: vague or ineffective instructions, confusing questions and response options, variable interpretation of terms, and misinterpretation of dietary recommendations. Interviews also provided insight into the meaning of diet-related stages of change. These findings concur with previous research suggesting that cognitive interview techniques are a valuable tool in the formative evaluation and development of nutrition surveys and materials.

Nutrition survey in Tabasco, Mexico: nutritional status of preschool children.

Nutritional status of 149 preschool children was evaluated using anthropometric, biochemical, and dietary measures. Stool samples were collected from 111 children for analysis of gastrointestinal parasites. Sixty-eight percent of the children were below the 3rd percentile of height-for-age, using Mexican reference data, but only 15% were below the 10th percentile of weight-for-height. The percentage of children with low biochemical values was: Hb, 14% less than 11 g/100 ml; hematocrit, 16% less than 34%; vitamin A, 36% less than 20 micrograms/100 ml; ascorbic acid, 47% less than 0.2 mg/100 ml; and riboflavin, 47% with EGR-AC greater than or equal to 1.35. None of the subjects had levels of serum albumin less than 3.5 g/100 ml. The average dietary intake was less than two-thirds of the Mexican Recommended Dietary Allowances for vitamin A, niacin, iron, calcium, and riboflavin. Energy and protein intake averaged 81 and 99% of the Recommended Dietary Allowances, respectively. Girls had significantly poorer growth and dietary intake than boys. Gastrointestinal parasites were detected in 75% of the stool samples, but no negative relationship between nutritional status and infection with the most common species (Ascaris, Trichuris, and Strongyloides) was found. Children were significantly thinner in the summer when diarrhea was most prevalent.

Conclusions from the Mexican National Nutrition Survey 1999: translating results into nutrition policy.

OBJECTIVE: This article presents and overview of the main results and conclusions from the Mexican National Nutrition Survey 1999 (NNS-1999) and the principal nutrition policy implications of the findings. MATERIAL AND METHODS: The NNS-1999 was conducted on a national probabilistic sample of almost 18,000 households, representative of the national, regional, as well as urban and rural levels in Mexico. Subjects included were children < 12 years and women 12-49 years. Anthropometry, blood specimens, diet and socioeconomic information of the family were collected. RESULTS: The principal public nutrition problems are stunting in children < 5 years of age; anemia, iron and zinc deficiency, and low serum vitamin C concentrations at all ages; and vitamin A deficiency in children. Undernutrition (stunting and micronutrient deficiencies) was generally more prevalent in the lower socioeconomic groups, in rural areas, in the south and in Indigenous population. Overweight and obesity are serious public health problems in women and are already a concern in school-age children. CONCLUSIONS: A number of programs aimed at preventing undernutrition are currently in progress; several of them were designed or modified as a result of the NNS-1999 findings. Most of them have an evaluation component that will inform adjustments or modifications of their design and implementation. However, little is being done for the prevention and control of overweight and obesity and there is limited experience on effective interventions. The design and evaluation of prevention strategies for controlling obesity in the population, based on existing evidence, is urgently needed and success stories should be brought to scale quickly to maximize impact.

Trends in childhood obesity in Japan over the last 25 years from the national nutrition survey.

OBJECTIVE: To describe the 25-year changes in BMI (measured in kilograms per meters squared) and the prevalence of obesity in Japanese children with special reference to urban-rural differences. RESEARCH METHODS AND PROCEDURES: We used the data sets from the cross-sectional annual nationwide surveys (National Nutrition Survey, Japan) conducted from 1976 to 2000 and comprising 29,052 boys and 27,552 girls between 6 and 14 years of age. We carried out the trend analyses with the data on sex and age groups and on residential areas according to the size of the municipality (metropolitan areas, cities, and small towns). RESULTS: The mean (age-adjusted) BMI increased by +0.32 kg/m(2) per 10 years in boys and by +0.24 kg/m(2) per 10 years in girls, increases that were remarkable in small towns. The prevalence of obese boys and girls increased from 6.1% and 7.1%, respectively, in the time-period 1976 to 1980, to 11.1% and 10.2% in 1996 to 2000. The increasing trend was most evident in 9- to 11-year-old children of both sexes living in small towns, whereas no changes were observed in girls in metropolitan areas. DISCUSSION: Our data clearly show increasing trends in obesity prevalence in Japanese school children. Degrees of the increasing trends, however, differed across sex and age groups and residential areas, demonstrating a particular phenomenon that girls in metropolitan areas were unlikely to become obese. These epidemiological aspects indicate the priorities for intervention in population strategies to control obesity in children.

Twenty-year changes in the prevalence of overweight in Japanese adults: the National Nutrition Survey 1976-95.

The aim of this study was to describe the 20-year changes in body mass index (BMI; kgm(-2)) and the prevalence of overweight in Japanese adults. Cross-sectional annual nationwide surveys (National Nutrition Survey, Japan) were carried out with a large probability sample of the Japanese population. Data sets of the 1976-95 surveys, comprising 91983 men and 120822 women (> or =20 years of age), were used. The analyses were carried out in age and gender groups, and by residential area according to the size of the municipality (metropolitan areas, cities and small towns). The mean BMI increaseed in men with an increment of +0.44 kg m(-2) 10 years(-1) and slightly decreased in women, by -0.09 kg m(-2) 10 years(-1), after adjustment for age. A decreasing trend of mean BMI was most significant in the female 20-29 years age-group (-0.38 kg m(-2) 10 years(-1)), in contrast to an increasing trend observed in elderly women (60-69 and 70+ years age-groups). The prevalence of preobese (BMI: 25-29.9kg m(-2)) and obese (BMI > or = 30 kg m(-2)) men increased from 14.5% and 0.8%, respectively, in the time-period 1976-80 to 20.5% and 2.01% during 1991-95. The increasing trend was most evident in the youngest age-group (20-29 years) and in those from small towns. The overall prevalence of preobese and obese women did not change during the 20-year study period. The prevalence in younger women decreased, this trend being more prominent in metropolitan areas. Although the prevalence of overweight (BMI > or =25 kg m(-2)) in Japanese men and elderly women has increased in the last 20 years, the mean BMI in younger women, especially those in metropolitan areas, has decreased. A population approach to control obesity and prevent obesity-associated diseases should be mainly focused on men and women older than 40 years of age.

[Results from nutritional surveys; their value for nutrition- and food science (author's transl)].

Various survey methods have been used in estimating the dietary intake of individuals, families and other groups. Every method has its advantages and disadvantages, and its practical, financial and technical difficulties. The choice is also limited by the quality of the population studied. The nutrient level is shown by many parameters: Cholesterol level, thiamine intake, uric acid level, ascorbic acid level in plasma, SO2-intake. Field studies were done with different groups of the population: pupils, elderly people living in homes, heavy workers, sedentary workers, clerks, policemen, sportsmen, students. SO2-intake is related with thiamin intake. It is very different from group to group (0,05--47,7 mg)/thiamin.

Kuwait nutritional survey: comparison of the nutritional status of Kuwaiti children aged 6-9 years with the NCHS/CDC reference population.

A national cross-sectional survey of the heights and weights of Kuwaiti primary school children aged 6-9 years was conducted on a stratified multistage sample of 5132 subjects from two socio-economic districts. The collected data were used to compare the nutritional status of Kuwaiti children with their American counterparts using the NCHS/CDC reference population. The basic indices used for comparison were height for age and weight for height, each considered in terms of centiles and SD scores and cross-classified using SD scores. The results indicated that although Kuwaiti children in the studied age groups are shorter than American children severe short stature is relatively infrequent as 48.3% fell below the 30th centile of the reference population. Conversely, Kuwaiti children are relatively heavier than American children as 61.1% fell above the 50th centile of the reference population.

Kuwait nutritional survey: comparison of the nutritional status of Kuwaiti children aged 0-5 years with the NCHS/CDC reference population.

A national cross-sectional survey of the heights and weights of Kuwaiti preschool-age children of 0-5 years was conducted on a stratified multistage sample of 2554 subjects from high and low socioeconomic levels. The collected data were used to compare the nutritional status of these children with their American counterparts using the NCHS/CDC reference population. The basic indices for comparison were height for age and weight for height, each considered in terms of centiles and standard deviation (SD) scores and cross-classified using the SD scores. The results indicated that Kuwaiti children in the studied age groups were shorter than American children, 47.7% falling below the 30th centile of the reference population. Conversely, the weights of Kuwaiti children aged 0-5 years were much closer to their American counterparts, 51.8% falling above the 50th centile of the reference population.

[Conclusions of the Canary Islands Nutrition Survey (1997-98). Foundations for a nutrition policy in Canary Islands].

The principal findings of the Canary Island Nutrition survey (ENCA). 1997-98 are presented. This survey was realised to obtain the following objectives: to evaluate eating habits and nutritional status utilising dietary, anthropometric and biochemical indicators in the Canary Island population along with determining lifestyle factors and the prevalence of the main cardiovascular risk factors. Additionally, a survey evaluating food-related knowledge and attitudes was also carried out. To attain this end, a cross-sectional study was realised in a representative sample of the Canary Island population aged 6 to 75 years (n = 1,747). This article summarises the key findings related to study objectives as well as study-derived recommendations to be realised within a Canary Island health and nutrition policy framework. For this purpose, the development of food based dietary guidelines addressed to meet target nutrients is needed.

Nutrient intake in Japanese adults --from The National Nutrition Survey, 1995-99.

The National Nutrition Survey is a unique survey that provides nationwide information on nutrient intake in Japan. Descriptive statistical data of nutrient intake, which has not been described in annual reports, are summarized in this report. A dataset from the National Nutrition Survey between 1995 and 1999 was used for analyses. The distribution of vitamin A intake had an extremely long right-hand tail and the difference between mean and median was very large. The results alert us to understand and use statistics properly when one summarizes the data. Means and medians of each nutrient intake except vitamin C were higher in men than in women, however, means and medians of nutrient density (per 1,000 kcal energy intake) for all nutrients were higher in women than in men. Fat intake was the highest in individuals in their 20 s and gradually declined in older age groups. Most of other forms of nutrient intake were the highest in individuals in their 50 s or 60 s and declined in older age groups. However, a declining trend with aging was not observed in the nutrient density of all nutrients except fat. These statistical data would support better interpretation of the survey data. Furthermore, some methodological limitations in the dietary assessment of the present survey, including the possibility of overestimating nutrient intake by not taking nutrient loss during the cooking process in households into account, were discussed. It is important to use and interpret the survey data under careful consideration on such methodological limitations.

Trends in national nutritional survey of Japan.

The nutritional status of the Japanese has been measured and evaluated annually on a nationwide scale since the first National Nutrition Survey was carried out in 1946. Changes in dietary intake levels could thus be monitored systematically at a national level. According to the results observed, the whole 50 years of the postwar period can be divided into three stages in terms of dietary intakes and their postulated health outcome. Although it has certain limitations for the purpose of analysis the survey has performed a remarkable role in throwing light upon the general trends and current status of nutrition in Japanese populations and thereby enabling a successful nutritional policy to be established.

Using national health and nutrition surveys for policy and programs: experiences from the demographic and health surveys.

National health and nutrition surveys have proved invaluable for policy and programs internationally, nationally and locally. With internationally comparable data, decisions can be made on trends and to monitor progress towards improving the nutritional status of women and children. In addition, the iterative process of survey and indicator development ensures that the use of the findings are fed back into the survey for improved design, data collection and measurements. Researchers, policy makers, program managers and surveyors work together for maternal child health.
