Selected AbstractsPhysical Activity, Dietary Practices, and Other Health Behaviors of At-Risk Youth Attending Alternative High SchoolsJOURNAL OF SCHOOL HEALTH, Issue 4 2004Martha Y. Kubik ABSTRACT: This study assessed the interest of alternative high school staff in intervention research on students' eating and physical activity habits und the feasibility of conducting such research in alternative school settings. A two-phase descriptive design incorporated both quantitative and qualitative methods. In fall/winter 2001,2002, alternative high school administrators in Minnesota were surveyed (response rate = 83%; n = 130/157). During summer 2002, one-on-one, semistruclured interviews were conducted with key-school personnel (n = 15) from urban and suburban schools. Findings indicated few schools had been invited to participate in research on nutrition (11%) and physical activity (7%). However, more than 80% of administrators reported interest in their students participating in such research. Most schools offered health and PE classes and had access to indoor gym facilities and outdoor play areas. While most schools offered a school lunch program, participation was low, cold lunches were common, and food often was unappealing. Beverage and snack vending machines were common. Overall, the physical environment of most alternative schools did not support physical activity and healthy eating as normative behavior. Interest in interventions on physical inactivity, unhealthy dietary practices, und other priority health-risk behavior common in students attending alternative schools was high among teachers and administrators. Results suggest research in alternative high schools is feasible and successful implementation and evaluation of programs possible. [source] Urinary sodium excretion, dietary sources of sodium intake and knowledge and practices around salt use in a group of healthy Australian womenAUSTRALIAN AND NEW ZEALAND JOURNAL OF PUBLIC HEALTH, Issue 4 2010Karen Charlton Abstract Objective: Strategies that aim to facilitate reduction of the salt content of foods in Australia are hampered by sparse and outdated data on habitual salt intakes. This study assessed habitual sodium intake through urinary excretion analyses, and identified food sources of dietary sodium, as well as knowledge and practices related to salt use in healthy women. Methods: Cross-sectional, convenient sample of 76 women aged 20 to 55 years, Wollongong, NSW. Data included a 24 hour urine sample, three-day food diary and a self-administered questionnaire. Results: Mean Na excretion equated to a NaCl (salt) intake of 6.41 (SD=2.61) g/day; 43% had values <6 g/day. Food groups contributing to dietary sodium were: bread and cereals (27%); dressings/sauces (20%); meat/egg-based dishes (18%); snacks/desserts/extras (11%); and milk and dairy products (11%). Approximately half the sample reported using salt in cooking or at the table. Dietary practices reflected a high awareness of salt-related health issues and a good knowledge of food sources of sodium. Conclusion: These findings from a sample of healthy women in the Illawarra indicate that dietary sodium intakes are lower in this group than previously reported in Australia. However, personal food choices and high levels of awareness of the salt reduction messages are not enough to achieve more stringent dietary targets of <4 g salt per day. Implications: Urinary Na excretion data are required from a larger nationally representative sample to confirm habitual salt intakes. The bread and cereals food group are an obvious target for sodium reduction strategies in manufactured foods. [source] Long chain polyunsaturated fatty acids (LC-PUFA) and perinatal developmentACTA PAEDIATRICA, Issue 4 2001B Koletzko This paper reports on the conclusions of a workshop on the role of long chain polyunsaturated fatty acids (LC-PUFA) in maternal and child health The attending investigators involved in the majority of randomized trials examining LC-PUFA status and functional outcomes summarize the current knowledge in the field and make recommendations for dietary practice. Only studies published in full or in abstract form were used as our working knowledge base. Conclusions: For healthy infants we recommend and strongly support breastfeeding as the preferred method of feeding, which supplies preformed LC-PUFA. Infant formulas for term infants should contain at least 0.2% of total fatty acids as docosahexaenoic acid (DHA) and 0.35% as arachidonic acid (AA). Since preterm infants are born with much less total body DHA and AA, we suggest that preterm infant formulas should include at least 0.35% DHA and 0.4% AA. Higher levels might confer additional benefits and should be further investigated because optimal dietary intakes for term and preterm infants remain to be defined. For pregnant and lactating women we consider it premature to recommend specific LC-PUFA intakes. However, it seems prudent for pregnant and lactating women to include some food sources of DHA in their diet in view of their assumed increase in LC-PUFA demand and the relationship between maternal and foetal DHA status. [source] Exploring the nutrition and lifestyle knowledge, attitudes and behaviour of student home economics teachers: baseline findings from a 4-year longitudinal studyINTERNATIONAL JOURNAL OF CONSUMER STUDIES, Issue 4 2008Mary Isobelle Mullaney Abstract It is widely acknowledged that obesity linked with reduced exercise contributes to health problems, and that, conversely, individuals who embark on weight reducing diets may become deficient in key nutrients. It is often advocated that these problems, which can be grouped together as poor dietary practice, be tackled through education. This study attempts to examine the relationship between nutrition education and lifestyle behaviours in a select group of third level students. The Irish Home Economics curriculum aims to teach secondary school pupils about nutrition and lifestyle practices conducive to health. However, the attitudes and lifestyle practices of those teaching this subject have never been examined in Ireland. The purpose of the present 4-year longitudinal study, whose first year findings are presented here, is to investigate the nutrition and lifestyle knowledge, attitudes and behaviours of a cohort of Irish student home economics teachers over the 4 years of their Bachelor of Education (Home Economics) degree course. The study was designed to explore possible changes in knowledge, attitudes and practices over the course of their professional education. Nutritional knowledge was measured using a 220-question adapted version of the test devised by Parmenter and Wardle. Attitudes were measured using a questionnaire adapted from the Pan-EU Survey on Consumer Attitudes to Physical Activity, Body-weight and Health. Food, alcohol consumption and exercise were measured using a 7-day reported dietary/exercise diary. Nutrient intake data were determined using dietary analysis. Weight, height and waist circumference were measured and body mass index (BMI) calculated. When starting college, student home economics teachers have broadly similar anthropometric, dietary and lifestyle characteristics to those of their contemporaries. Mean BMI was identical [24.4 kg/m2 (SD 4.3)] to that reported in the North/South Ireland Food Consumption Survey (NSIFCS) for those aged 18,35 years, although energy intakes were significantly higher in the cohort of student teachers (P = 0.000). Thirty-eight per cent were overweight or obese vs. 33.6% in the NSIFCS. Only 17% (n = 6) of students achieved an intake of 300 µg/day of folate as recommended by the Food Safety Authority of Ireland and only one the recommended intake of non-starch polysaccharides (18 g/day). One in three students in this study smoke (16 of 48) and alcohol consumption was high. Only one student was very active. Students scored a mean of 55% (SD 8%) on the knowledge test, with similar scores attained for specific aspects of nutritional knowledge (i.e. food groups, constituents of foods, current dietary advice, nutrients, lifestyle practices). However, knowledge of nutrition definitions was weaker with a mean score of 31% (SD 8.6%). Students had a positive attitude towards food choice, the link between food and health and control over their own diet. Similar attitudes towards exercise, smoking and alcohol consumption were displayed despite students perceiving themselves as not having a balanced diet, having insufficient exercise and having regretted something done as a result of consuming alcohol. They appear to display optimistic bias in relation to health risks. These findings provide baseline data for the longitudinal study and indicate that those choosing to pursue a career as a home economics teacher in Ireland have similar nutritional and lifestyle characteristics to those of their contemporaries. [source] An exploration of nutritional knowledge in a sample of Scottish men of low socio-economic statusNUTRITION BULLETIN, Issue 4 2000Kerri E. McPherson Summary The government has used health promotion campaigns as a means of improving nutritional knowledge in the Scottish population, in an attempt to encourage healthier eating practices and reduce diet-related illness. However, mismeasurement of nutritional knowledge and the presence of barriers to behaviour change, such as socio-economic status, means that the relationship between nutritional knowledge and dietary practice is not a straightforward one. The main findings of the present study are twofold. Firstly, the results emphasise the multidimensionality of the nutritional knowledge construct. Secondly, the results show that educational status is a major facilitator/barrier in the nutritional knowledge,dietary practice relationship. [source] The role of diet in the management of gout: a comparison of knowledge and attitudes to current evidenceJOURNAL OF HUMAN NUTRITION & DIETETICS, Issue 1 2009P. Shulten Abstract Background:, Evidence supports dietary modifications in the management of gout. Despite this, the degree of implementation of this evidence by nutrition professionals and rheumatologists and those affected by gout is unknown. The present study aimed to compare usual dietary practices of patients with gout to evidence for dietary management of gout and to investigate whether the knowledge and attitudes of nutrition professionals and rheumatologists reflects current evidence. Methods:, A food frequency questionnaire was used to determine usual dietary intake of patients with gout, a separate questionnaire examined gout-related dietary modifications (n = 29). Online questionnaires to examine attitudes towards dietary management of gout were completed by nutrition professionals and rheumatologists. Results:, Proportions of participants whose reported intakes were inconsistent with current evidence for the dietary management of gout were: alcohol, n = 14 (48%); beer, n = 18 (62%); seafood, n = 29 (100%); meat, n = 7 (24%); beef/pork/lamb, n = 24 (83%); dairy products, n = 12 (41%); vitamin C supplementation, n = 29 (100%). Of the 61 rheumatologists and 231 nutrition professionals who completed the online survey, the majority considered that weight loss and decreased alcohol intake were important or very important outcomes. Proportions were lower for decreased purine intake. Thirty-four (56%) rheumatologists do not refer patients with gout to dietetic services and, of those who do, the majority refer less than half. Conclusions:, Overall, patients with gout in the present study were not implementing evidence for dietary management of their condition and complex dietary issues were evident. [source] What British children are eating and drinking at age 12,18 monthsJOURNAL OF HUMAN NUTRITION & DIETETICS, Issue 2 2000A. De La Hunty Background Health and growth during the first 2 years of life demand adequate nutrition. Proportionate to the toddler's size, the nutrient requirements exceed those of adults by up to six-fold. Objective This study reports the first national survey to assess the diets of British children at 14 months. Methods The data were gathered by postal questionnaire sent to the mothers who had participated in the 1995 National Survey of Infant Feeding. The results were evaluated in respect of the recommendations from COMA for the UK. Results A total of 5069 children of average age 14 months were included. Bread and cereal were consumed frequently. Fifty per cent of the children ate raw fruit, 51% ate cooked vegetables, 34% ate meat and 76% drank cow's milk daily. Consumption of sweetened drinks (such as squashes and carbonated drinks) was common. This study confirmed the influence of social, economic and educational inequalities on dietary practices. [source] Maternal Self-Report of Oral Health in 4-Year-Old Pacific Children from South Auckland, New Zealand: Findings from the Pacific Islands Families StudyJOURNAL OF PUBLIC HEALTH DENTISTRY, Issue 2 2007Philip J. Schluter PhD Abstract Objectives: To report on the oral health risk in a disadvantaged group of 4-year-old Pacific children and their mothers living in South Auckland, New Zealand. Methods: The Pacific Islands Families study follows a cohort of Pacific infants born in 2000. Maternal self-report of mother and child's oral health practices and child's filling and extraction experience was undertaken at interview approximately 4 years postpartum. Results: Overall, 1,048 mothers of children were interviewed. Children's reported oral health practices were generally poor, with 47 percent brushing ,1/day, 47 percent having no adult assistance with brushing, 57 percent routinely snacking or drinking immediately prior to bed, and 26 percent yet to receive their first dental checkup. Maternal practices were also poor, with 34 percent brushing ,1/day and 50 percent having never seen or last visiting a dentist over 5 years ago. Significant differences were seen in many practices between the major ethnic subgroups. Of children attending the school dental service, 22 percent were reported having at least one filling and/or extraction. In multivariable analyses, variables corresponding to mother's toothbrushing frequency, child snacking or drinking prior to bed, and duration of breastfeeding were significantly associated with reported filling and/or extraction experience; but no difference was seen between the three major maternal ethnic subgroups. Conclusions: Many mothers and their Pacific children have poor basic oral hygiene and dietary practices that increase the oral health risk in these children. Culturally appropriate and targeted strategies aimed at these modifiable practices need to be widely promoted so that the oral health burden carried by Pacific children can be reduced.

[source] Southern French Neolithic populations: Isotopic evidence for regional specificities in environment and dietAMERICAN JOURNAL OF PHYSICAL ANTHROPOLOGY, Issue 2 2010Estelle Herrscher Abstract The Middle Neolithic of the Northwestern Mediterranean area (,4500,3500 BC cal) is characterized by the development of food production techniques as well as by increasing social complexity. These characteristics could have had an impact on human dietary patterns. To evaluate human dietary practices and lifeways of the Middle Neolithic populations from the South of France, stable carbon and nitrogen isotope analysis was carried out on 57 human and 53 faunal bones from seven archaeological sites located in the Languedoc and Garonne regions between 20 and 100 km from the Mediterranean Sea, respectively. Results show regional differences in carbon isotope values. Animal and human bones from the Languedoc region are significantly enriched in 13C relative to the Garonne. Conversely, human and dog bones from the Garonne region are significantly enriched in 15N compared to human and dog bones from the Languedoc region. These results highlight the importance of the local ecosystem in human and animal diet as well as a regional differentiation of palaeodietary behavior, which probably relates to economic and social factors. The comparison of stable isotope data with archaeological and biological evidence does not show any significant intra- or interpopulation differences. However, the presence of human outliers suggests that migration probably occurred, perhaps in relation to the trade of animals and/or materials. This study also highlights the importance of investigating local animal stable isotope values for the interpretation of human palaeodiet. Am J Phys Anthropol 2010. © 2009 Wiley-Liss, Inc. [source] The ecology and evolutionary endocrinology of reproduction in the human femaleAMERICAN JOURNAL OF PHYSICAL ANTHROPOLOGY, Issue S49 2009Virginia J. Vitzthum Abstract Human reproductive ecology (HRE) is the study of the mechanisms that link variation in reproductive traits with variation in local habitats. Empirical and theoretical contributions from biological anthropology, physiology, and demography have established the foundation necessary for developing a comprehensive understanding, grounded in life history theory (LHT), of temporal, individual, and populational variation in women's reproductive functioning. LHT posits that natural selection leads to the evolution of mechanisms that tend to allocate resources to the competing demands of growth, reproduction, and survival such that fitness is locally maximized. (That is, among alternative allocation patterns exhibited in a population, those having the highest inclusive fitness will become more common over generational time.) Hence, strategic modulation of reproductive effort is potentially adaptive because investment in a new conception may risk one's own survival, future reproductive opportunities, and/or current offspring survival. The hypothalamic-pituitary-ovarian (HPO) axis is the principal neuroendocrine pathway by which the human female modulates reproductive functioning according to the changing conditions in her habitat. Adjustments of reproductive investment in a potential conception are manifested in temporal and individual variation in ovarian cycle length, ovulation, hormone levels, and the probability of conception. Understanding the extent and causes of adaptive and non-adaptive variation in ovarian functioning is fundamental to ascertaining the proximate and remote determinants of human reproductive patterns. In this review I consider what is known and what still needs to be learned of the ecology of women's reproductive biology, beginning with a discussion of the principal explanatory frameworks in HRE and the biometry of ovarian functioning. Turning next to empirical studies, it is evident that marked variation between cycles, women, and populations is the norm rather than an aberration. Other than woman's age, the determinants of these differences are not well characterized, although developmental conditions, dietary practices, genetic variation, and epigenetic mechanisms have all been hypothesized to play some role. It is also evident that the reproductive functioning of women born and living in arduous conditions is not analogous to that of athletes, dieters, or even the lower end of the "normal range" of HPO functioning in wealthier populations. Contrary to the presumption that humans have low fecundity and an inefficient reproductive system, both theory and present evidence suggest that we may actually have very high fecundity and a reproductive system that has evolved to be flexible, ruthlessly efficient and, most importantly, strategic.

[source] Geographical patterns of human diet derived from stable-isotope analysis of fingernailsAMERICAN JOURNAL OF PHYSICAL ANTHROPOLOGY, Issue 1 2006Gabriela B. Nardoto Abstract Carbon and nitrogen isotope ratios of human fingernails were measured in 490 individuals in the western US and 273 individuals in southeastern Brazil living in urban areas, and 53 individuals living in a moderately isolated area in the central Amazon region of Brazil and consuming mostly locally grown foods. In addition, we measured the carbon and nitrogen isotope ratios of common food items to assess the extent to which these isotopic signatures remain distinct for people eating both omnivorous and vegetarian diets and living in different parts of the world, and the extent to which dietary information can be interpreted from these analyses. Fingernail ,13C values (mean ± standard deviation) were ,15.4 ± 1.0 and ,18.8 ± 0.8, and ,15N values were 10.4 ± 0.7 and 9.4 ± 0.6, for southeastern Brazil and western US populations, respectively. Despite opportunities for a "global supermarket" effect to swamp out carbon and nitrogen isotope ratios in these two urbanized regions of the world, differences in the fingernail isotope ratios between southeastern Brazil and western US populations persisted, and appeared to be more associated with regional agricultural and animal production practices. Omnivores and vegetarians from Brazil and the US were isotopically distinct, both within and between regions. In a comparison of fingernails of individuals from an urban city and isolated communities in the Amazonian region, the urban region was similar to southeastern Brazil, whereas individuals from isolated nonurban communities showed distinctive isotopic values consistent with their diets and with the isotopic values of local foods. Although there is a tendency for a "global supermarket" diet, carbon and nitrogen isotopes of human fingernails hold dietary information directly related to both food sources and dietary practices in a region.

Okobia MBBS Abstract: The recent upsurge in global obesity and the recognition of the role of metabolic syndrome and other correlates of obesity in the etiology of breast cancer and other chronic diseases has created the impetus for renewed interest in the role of anthropometric measures in breast cancer risk. This case-control study was designed to evaluate the role of anthropometric variables in breast cancer susceptibility in an indigenous sub-Saharan African population drawn from midwestern and southeastern Nigeria, a population grossly underreported in the global epidemiologic literature. Study participants were 250 women with breast cancer who were receiving treatment in the surgical outpatient clinics and surgical wards of four university teaching hospitals located in midwestern and southeastern Nigeria, while the controls were 250 age-matched women without breast cancer or other malignant diseases being treated for other surgical diseases in the same institutions between September 2002 and April 2004. Waist:hip ratio (WHR) was associated with a significant 2.5-fold increased risk of premenopausal breast cancer (odds ratio [OR] = 2.56, 95% confidence interval [CI] 1.48,4.41] and a 2-fold increased risk of postmenopausal breast cancer (OR = 2.00, 95% CI 1.04,2.53). Increasing height conferred a modestly nonsignificant increased risk of premenopausal breast cancer (OR = 1.59, 95% CI 0.98,2.58). The study showed that WHR is a significant predictor of breast cancer risk in Nigerian women and measures to sustain increased physical activity and ensure healthy dietary practices are recommended to reduce the burden of obesity in the population.
