Urbanisation and cariogenic food habits among 4-24-month-old black South African children in rural and urban areas.

OBJECTIVE: To determine if social class, education level and group environment (rural and urban) influence particular food habits commonly associated with dental caries incidence among 4-24-month-old black South African children. DESIGN, SETTING AND SUBJECTS: Information was collected by trained interviewers using a food-frequency questionnaire from mothers of children in two areas in South Africa: Ndunakazi, a rural area in KwaZulu/Natal (n = 105) and two urban areas in Gauteng - Soweto (low to middle socio-economic area) (n = 100) and the northern suburbs of Johannesburg and Sandton (middle to upper socio-economic area) (n = 101). Education level and occupation of the parents, which define social class, were also recorded. A linear logistic (Proc Catmod) analysis tested social class, education level and group environment as the independent variables and the food habits as the dependent variables. RESULTS: Group environment was significantly associated with nine of the 18 food habits investigated. More urban than rural mothers added sugar to their child's comforter. More mothers in urban Soweto than in urban Johannesburg were still breast-feeding their infants at 24 months. More rural than urban mothers were giving 'mutis' (common and traditional medicines). Together with group environment, education level was significantly associated with giving of 'mutis' and the frequency of giving them. Social class was significantly associated with the frequency of breast-feeding and when the child was breast-fed. Mothers from the upper social class breast-fed less frequently than mothers from the lower class. CONCLUSION: The study showed a strong influence of rural/urban environment on specific cariogenic food habits among young black South African children, enabling the development and implementation of a nutrition strategy.

Having lunch at a staff canteen is associated with recommended food habits.

OBJECTIVE: To describe the characteristics of employees having lunch at staff canteens and to examine the association between workplace lunch and recommended food habits. DESIGN: A mailed questionnaire including data on lunch pattern, food habits, sociodemographic background, work-related factors and body weight. Logistic regression models including food habits as dependent variables and lunch pattern, sociodemographic factors, work-related factors and body mass index as independent variables. SETTING: Helsinki Health Study survey data, collected in spring 2001. SUBJECTS: Employees from the City of Helsinki reaching 40, 45, 50, 55 and 60 years. The data included 2474 women and 591 men; the response rate was 68%. RESULTS: About half of those with a staff canteen at work had lunch there. Those with higher educational level were more likely to have lunch at the staff canteen, as also were women with pre-school children and normal-weight men. Those having lunch at staff canteens were more likely to follow recommended food habits, compared with other subjects. Having lunch at the staff canteen seemed to increase the consumption frequency of vegetables and fish. CONCLUSIONS: Having lunch at staff canteens is associated with the quality of the diet. To serve a cooked meal including vegetables during working time may be an efficient way to improve diet among adult employees. More emphasis should be put on increasing the possibility for employees to have lunch at staff canteens.

A comparison of dietary habits among women in Japan and Hawaii.

OBJECTIVE: To compare the dietary habits of Japanese women in Japan with those of Japanese and Caucasian women living in Hawaii. DESIGN: Data from two previous cross-sectional studies conducted within two years in Hawaii and Gifu, Japan were pooled and analysed. Dietary intakes were assessed with validated food-frequency questionnaires and urine samples were collected for isoflavone measurement. SETTING: Participants were recruited through mammography clinics in both locations. SUBJECTS: In Hawaii, 164 Caucasian and 146 Japanese women; in Japan, 206 women. RESULTS: Dietary habits differed considerably by ethnicity and location. In comparison to the Caucasian diet, the diet in Japan was relatively low in fat and high in carbohydrates and protein, whereas the Japanese women in Hawaii reported intermediate intakes. Japanese women in Gifu consumed a diet that was relatively high in fish, soy, eggs and vegetables, and low in fruits, dairy products and meat. In contrast, the Caucasian women consumed the most dairy products and fruits and the Japanese women in Hawaii reported the highest grain and meat intakes. CONCLUSIONS: The diet of Japanese women in Hawaii appeared to be a combination of foods eaten in Japan and the dietary habits of Caucasian women in Hawaii, but eating habits in Japan are also different from traditional nutritional patterns. This study illustrates several problems related to dietary comparisons across populations and provides information for future investigations on chronic disease risk.

Leisure-time and occupational physical activity in relation to cardiovascular risk factors and eating habits in French adults.

OBJECTIVE: To investigate the relationships of two main physical activity domains (during leisure and at work) with cardiovascular risk factors and eating habits. DESIGN: Cross-sectional study. SETTING: Preventive medicine centre. SUBJECTS: In 5478 adults (32% women, aged 20-80 years) who consecutively underwent a standardised health examination, leisure-time physical activity (LTPA; i.e. non-sport leisure and sport activities), occupational physical activity (OPA) and eating habits were assessed by self-administered questionnaires. We analysed sex-specific relationships of LTPA and OPA (in quartiles) with (1) various cardiovascular risk factors and (2) eating habits using analysis of variance and logistic regression, respectively. RESULTS: In both genders, with and without adjustment for education in addition to age, LTPA was associated negatively with body mass index, body fat, waist circumference, resting heart rate, diastolic blood pressure and triglycerides, and positively associated with high-density lipoprotein cholesterol (all P < or = 0.005). OPA adjusted for age only was positively associated with most cardiovascular risk factors but these associations were not significant after further adjustment on education (except for waist circumference in women). Age- and education-adjusted LTPA was associated with increased frequency of consumption of fruits (odds ratio (OR) = 2.05, 95% confidence interval (CI) 1.68-2.52 in men; OR = 1.90, 95% CI 1.41-2.05 in women) and vegetables (OR = 1.81, 95% CI 1.48-2.21 in men; OR = 2.22, 95% CI 1.66-2.97 in women). CONCLUSIONS: The data emphasise the favourable associations of LTPA, a modifiable behaviour, with various cardiovascular risk factors and healthy eating habits. The results also suggest that the relationships of OPA with cardiovascular risk factors depend, at least in part, on socio-economic status as reflected by educational level.

Disparities in food habits across Europe.

Socially-and culturally-patterned differences in food habits exist both between and within European populations. Daily individual food availability data, collected through the national household budget surveys (HBS) and harmonized in the context of the Data Food Networking (DAFNE) project, were used to assess disparities in food habits of seven European populations and to evaluate dietary changes within a 10-year interval. The availability of selected food items was further estimated according to the educational level of the household head and, based only on the Greek HBS data, according to quintiles of the household's food purchasing capacity. Results for overall food availability support the north-south differentiation in food habits. Generally, the availability of most food items, including foods such as vegetable fats, animal lipids and sugar products, has decreased over the 10 years. Households in which the head was in the higher education categories reported lower availability for most food items, with the exception of low-fat milk, fresh fruit, animal lipids and soft drinks; the latter showing a sharp increase even within southern European households. The household's food purchasing capacity can be used as an indicator of socio-economic status, with higher values being associated with lower status. Greek households of lower social class follow a healthier diet in terms of greater availability of vegetable oils, fresh vegetables, legumes, fish and seafood. Data from the DAFNE databank may serve as a tool for identifying and quantifying variation in food habits in Europe, as well as for providing information on the socio-economic determinants of food preferences.

Modification of crystal habit and its role in dosage form performance.

Crystallization is often employed for purifying a drug substance. Use of different solvents and processing conditions may change the crystal habit, besides altering the polymorphic state. Furthermore, altered habit may result from crystal growth during storage. Hence, there is a need to understand the factors influencing crystal habit and to evaluate critically, its role in the performance of dosage forms. Establishing the physicotechnical properties of different habits of a drug will help to recognize lot-to-lot variations in raw materials and to ensure reproducibility of dosage form performance.

Comparative analysis of cutaneous evaporative water loss in frogs demonstrates correlation with ecological habits.

Most frog species show little resistance to evaporative water loss (EWL), but some arboreal species are known to have very high resistances. We measured EWL and cutaneous resistance to evaporation (Rc) in 25 species of frogs from northern Australia, including 17 species in the family Hylidae, six species in the Myobatrachidae, and one each in the Bufonidae and the Microhylidae. These species display a variety of ecological habits, including aquatic, terrestrial, and arboreal specialisations, with the complete range of habits displayed within just the one hylid genus, Litoria. The 25 species measured in this study have resistances that range from Rc=0 to 63.1. These include low values indistinguishable from a free water surface to high values typical of "waterproof" anuran species. There was a strong correlation between ecological habit and Rc, even taking phylogenetic relationships into account; arboreal species had the highest resistance, aquatic species tended to have little or no resistance, and terrestrial species tended to have resistance between those of arboreal and aquatic frogs. For one species, Litoria rubella, we found no significant changes in EWL along a 1,500-km aridity gradient. This study represents the strongest evidence to date of a link between ecological habits and cutaneous resistance to water loss among species of frogs.

Delayed gratification habitable zones: when deep outer solar system regions become balmy during post-main sequence stellar evolution.

Like all low- and moderate-mass stars, the Sun will burn as a red giant during its later evolution, generating of solar luminosities for some tens of millions of years. During this post-main sequence phase, the habitable (i.e., liquid water) thermal zone of our Solar System will lie in the region where Triton, Pluto-Charon, and Kuiper Belt objects orbit. Compared with the 1 AU habitable zone where Earth resides, this "delayed gratification habitable zone" (DGHZ) will enjoy a far less biologically hazardous environment - with lower harmful radiation levels from the Sun, and a far less destructive collisional environment. Objects like Triton, Pluto-Charon, and Kuiper Belt objects, which are known to be rich in both water and organics, will then become possible sites for biochemical and perhaps even biological evolution. The Kuiper Belt, with >10(5) objects > or =50 km in radius and more than three times the combined surface area of the four terrestrial planets, provides numerous sites for possible evolution once the Sun's DGHZ reaches it. The Sun's DGHZ might be thought to only be of academic interest owing to its great separation from us in time. However, approximately 10(9) Milky Way stars burn as luminous red giants today. Thus, if icy-organic objects are common in the 20-50 AU zones of these stars, as they are in our Solar System (and as inferred in numerous main sequence stellar disk systems), then DGHZs may form a niche type of habitable zone that is likely to be numerically common in the Galaxy.

Do eating habits differ according to alcohol consumption? Results of a study of the French cohort of the European Prospective Investigation into Cancer and Nutrition (E3N-EPIC).

BACKGROUND: The potential of dietary habits to confound the association between alcohol consumption and health needs further study. OBJECTIVE: We examined whether eating habits differed according to alcohol consumption in a large cohort of French women. DESIGN: This was a cross-sectional study of the French cohort of the European Prospective Investigation into Cancer and Nutrition (E3N-EPIC). The cohort was established in 1990 and includes 100000 women born between 1925 and 1950. Dietary data were obtained between 1993 and 1995 by using self-administered food-frequency questionnaires. About 73000 questionnaires were analyzed, and women were placed into 7 categories of alcohol consumption. RESULTS: After adjustment for energy derived from alcohol, increasing alcohol consumption was associated with a higher total energy intake, a higher percentage of energy intake as protein and lipids, and higher intakes of cholesterol, fatty acids, retinol, iron, and vitamin E. Conversely, energy provided by carbohydrates decreased with increasing alcohol consumption, as did beta-carotene intake. Increasing alcohol consumption was associated with higher consumption of animal products, cheese, potatoes, oil, bread, and breakfast cereals and with lower consumption of vegetables and dairy products. CONCLUSION: In this population of middle-aged, highly educated French women, marked differences in dietary patterns and nutrient intakes were found according to alcohol consumption. Part of the detrimental effect of alcohol on health may be due to the less healthy dietary habits of drinkers. This points to a confounding role of eating habits and nutrient intakes in the relation between alcohol and health.

Lifetime smoking habits among Norwegian men and women born between 1890 and 1974.

BACKGROUND: The aims of the present study were to provide lifetime smoking data for epidemiological studies of tobacco-induced cancer in Norway, and to sort out the influence of age, gender, and period on the population's smoking habits in this century. METHODS: We used annual surveys of smoking habits from 1954 to 1992, and individual lifetime smoking histories collected in 1965 from a population sample born 1893-1927. The population was divided into 5-year sex-and-birth cohorts born between 1890 and 1974, and smoking habits were described as the proportion of current smokers in 5-year age groups between 15 and 74 years old. We also estimated the average tobacco consumption per smoker by calendar year after 1930. RESULTS: The proportion of smokers increased with each succeeding cohort of men and women until the 1950s, when the highest proportion of male smokers (76-78%) was observed among those born 1915-1934. This peak was followed by a decline in both men and women from 1955 to 1965. A second peak occurred in women around 1970, during which the highest proportion of smokers (52%) was observed in women born 1940-1949. From 1970 to 1990 smoking has declined in all cohorts of men and women, but at a slower rate after 1980 in the younger cohorts. The smoking proportion was more than five times higher in men than in women born 1890-1894, but the gap has declined with each succeeding cohort until no gender difference was present among those born after 1950. The average tobacco consumption per smoker between 1930 and 1950 remained fairly constant around 8.5 g per day in male smokers and 6 g per day in female smokers, followed by a continuous increase to 15 g per day in men and 12 g in women in 1985. CONCLUSIONS: The smoking habits in Norway appear to have been strongly influenced by social changes and the increasing awareness of the health hazards of smoking. Each cohort's response to these events has depended on the members' age and sex at the time.

A comparison of food habit and food frequency data as predictors of breast cancer in the NHANES I/NHEFS cohort.

We compared two methods of assessing dietary fat and breast cancer incidence in the first complete follow-up of the National Health Epidemiologic Follow-up Study (NHEFS) cohort. Between 1982 and 1984, 6156 women aged 32-86 y completed the NHEFS survey, which included a 93-item food frequency questionnaire (FFQ). In addition, women answered questions regarding food habits, such as choice of salad dressing, trimming fat from meat, and eating skin on poultry. In the 4 y of follow-up, these women contributed a total of 23,949 person years, during which 53 women reported a breast cancer diagnosis. The rate ratio (RR) and 95% confidence interval (CI) for each quartile of percentage of energy from fat were 1.0, 0.96 (0.5-2.1), 1.0 (0.5-2.2) and 0.98 (0.5-2.1). Thus the breast cancer rates for women in the upper three quartiles, who reported a diet with higher than 30% of energy from fat, were not different from those of women in the lowest quartile of intake (< or = 29.4% energy from fat). In contrast, the "high-fat" response to three of the four food habit questions identified women at increased risk of developing breast cancer: women who used salad dressings other than low fat had a RR and 95% CI of 1.3 (0.7-2.3), women who reported eating the skin on poultry had a RR and 95% CI of 1.7 (0.9-2.9), and women who did not use lean or extra lean ground beef had a RR and 95% CI of 2.2 (1.2-4.0). These food habit questions may be less subject to misclassification than dietary information of fat intake derived from the FFQ. Further investigation is needed to evaluate what is measured by the food habit questions.

Treatment failure and dietary habits in women with breast cancer.

BACKGROUND: Epidemiological and experimental evidence suggests that breast cancer risk can be reduced by dietary measures. Study of the relationships between dietary habits and prognosis in patients with breast cancer is essential to the design of diet intervention trials. PURPOSE: Our purpose was to determine whether dietary habits are associated with disease-free survival in patients with breast cancer who have undergone treatment. METHODS: We interviewed 240 women about their dietary histories. These women were 50-65 years old and had pathological stage I-II breast cancer with subsequent follow-up for 4 years; 209 of these women were postmenopausal. Differences in dietary variables between groups of patients were analyzed with bivariate and multivariate statistical methods. RESULTS: Cancers were classified as estrogen receptor (ER) rich (> or = 0.10 fmol/micrograms of DNA) in 149 patients and as ER poor (< 0.10 fmol/micrograms of DNA) in 71 patients. Fifty-two patients had treatment failure during follow-up. The 30 patients with ER-rich tumors who had treatment failure reported higher intakes of total fat, saturated fatty acids, and polyunsaturated fatty acids than did the 119 patients with ER-rich tumors who did not have treatment failure. The multiple-odds ratio (OR) for treatment failure in these women was 1.08 for each 1% increment in percentage of total energy (E%) from total fat. For treatment failure within the first 2 years, the OR was 1.19 for each 1-mg increase in vitamin E intake per 10 megajoules of energy. In women with treatment failure 2-4 years after diagnosis, ORs were 1.13 and 1.23 for each E% increment in total fat or saturated fatty acids, respectively. No association between dietary habits and treatment failure was found for women with ER-poor cancers. There was a tendency to a dose-response relationship (in quartiles) between intake of saturated fatty acids and disease-free survival, but the observed differences were not statistically significant. CONCLUSIONS: Dietary habits at the time of diagnosis may affect prognosis, at least for patients with ER-rich breast cancers. Dietary fat may have an effect on growth or spread of breast cancer, both of which may vary according to type of fat. Total fat and saturated fatty acids were the dietary parameters most strongly associated with risk for treatment failure. IMPLICATIONS: Dietary intervention might serve as an adjuvant treatment to improve breast cancer prognosis.

Relationship between oral parafunctional/nutritive sucking habits and temporomandibular joint dysfunction in primary dentition.

UNLABELLED: The aim of this study was to evaluate the relationship between nutritive and parafunctional habits and the presence of temporomandibular dysfunction (TMD) in children with primary dentition. METHODS: Ninety nine children, aged 3-5 years, were examined to check for the presence or absence of signs and symptoms of TMD (headache, preauricular pain, earache, masticatory muscle tenderness, deviation on opening, occlusal interference and asymmetric movement of the mandible), oral parafunctions (bruxism, nail biting, finger/thumb sucking, speech alteration, mouth breathing, pacifier and atypical swallowing) and nutritive habits (breast- or bottle-feeding) through interview and clinical examination. The results were submitted to descriptive statistical analysis and Fisher's exact test. RESULTS: The results showed that only atypical swallowing was positively related to TMD (P < 0.0001); other oral parafunctional and nutritive habits were not related to TMD. CONCLUSIONS: It was concluded that parafunctional habits, with the exception of atypical swallowing, and feeding methods were not determinants for the presence of signs and/or symptoms of TMD in the sample of children included in the study.

Eating habits, smoking and toothbrushing in relation to dental caries: a 3-year study in Swedish female teenagers.

OBJECTIVES: The aims of the present study were to describe eating, toothbrushing and smoking habits in a cohort of Swedish female adolescents, and to relate the findings to dental caries increment. DESIGN: The research took the form of a longitudinal study. SUBJECTS AND METHODS: The study sample consisted of a cohort of 162 girls under regular dental care, aged 12 years at baseline, who were followed for 3 years, from the sixth to the ninth grade. Eating, oral cleaning and smoking habits were self-reported three times per year through a questionnaire, and caries data at baseline and after 3 years were collected from dental records. RESULTS: The results showed significantly (P < 0.05) impaired eating habits during the study period and that adherence to regular main meals diminished. In the eighth grade, one-third of the girls skipped breakfast before school and only 50% had their free school lunch daily. The omission of breakfast and irregular main meals, as well as smoking were significantly associated with caries (decayed, missed and filled surfaces) increment in the eighth grade (odds ratio = 4.1-4.9, P < 0.05). Snacks, light meals, soft drinks and sweets were already frequently consumed at baseline and continued to be so over the years. Although > 95% of subjects reported that they brushed their teeth at least once a day, approximately 20% did not do it every evening, and this figure remained stable over the study period. However, snacks, soft drinks and sweets, and toothbrushing habits had no significant influence on caries development. CONCLUSION: Dietary advice for caries prevention in adolescent girls should focus on the importance of retaining regular main meals, and especially, not skipping breakfast.

Analysis of the moral habitability of the nursing work environment.

BACKGROUND: Following health reform, nurses have experienced the tremendous stress of heavy workloads, long hours and difficult professional responsibilities. In recognition of these problems, a study was conducted that examined the impact of the working environment on the health of nurses. After conducting focus groups across Canada with nurses and others well acquainted with nursing issues, it became clear that the difficult work environments described had significant ethical implications. AIM: The aim of this paper is to report the findings of research that examined the moral habitability of the nursing working environment. METHODS: A secondary analysis was conducted using the theoretical work of Margaret Urban Walker. Moral practices and responsibilities from Walker's perspective cannot be extricated from other social roles, practices and divisions of labour. Moral-social orders, such as work environments in this research, must be made transparent to examine their moral habitability. Morally habitable environments are those in which differently situated people experience their responsibilities as intelligible and coherent. They also foster recognition, cooperation and shared benefits. FINDINGS: Four overarching categories were developed through the analysis of the data: (1) oppressive work environments; (2) incoherent moral understandings; (3) moral suffering and (4) moral influence and resistance. The findings clearly indicate that participants perceived the work environment to be morally uninhabitable. The social and spatial positioning of nurses left them vulnerable to being overburdened by and unsure of their responsibilities. Nevertheless, nurses found meaningful ways to resist and to influence the moral environment. CONCLUSIONS: We recommend that nurses develop strong moral identities, make visible the inseparability of their proximity to patients and moral accountability, and further identify what forms of collective action are most effective in improving the moral habitability of their work environments.

Association between sharing of toothbrushes, eating and drinking habits and the presence of Actinobacillus actinomycetemcomitans in Moroccan adolescents.

BACKGROUND/AIMS: Actinobacillus actinomycetemcomitans is frequently detected in dental plaque collected from Moroccan adolescents, and has been shown to be associated with clinical attachment loss in this population. The aim of this study was to assess whether behaviors such as the sharing of toothbrushes, and eating and drinking habits were associated with the presence of A. actinomycetemcomitans in Moroccan adolescents. MATERIALS AND METHODS: A total of 121 adolescents were clinically examined. Interviews regarding sharing of toothbrushes, eating and drinking habits were performed, and plaque samples were collected and analyzed for A. actinomycetemcomitans with different leukotoxin promoter types by polymerase chain reaction. Based on eating and drinking habits, the study population was divided in a low risk behavior group (LRB) and a high risk behavior group (HRB). RESULTS: No association was found between the sharing of toothbrushes and the presence of A. actinomycetemcomitans. The odds ratios between the HRB and LRB group for being positive for the JP2 type, for non-JP2 types, and for any type of A. actinomycetemcomitans were 4.74 (95% CI 0.55; 40.71), 2.49 (95% CI 1.03; 5.97), and 2.97 (95% CI 1.28; 6.91), respectively. The difference in the mean number of teeth with a clinical attachment loss of > or = 3 mm between the HRB and the LRB group was 0.91(95% CI 0.09; 1.72). CONCLUSION: Sharing of toothbrushes does not seem to be associated with the presence of A. actinomycetemcomitans in young Moroccans. Eating and drinking habits conducive to exchange of saliva are positively associated with presence of A. actinomycetemcomitans, and with a higher level of clinical attachment loss.

Health habits and risk of cognitive impairment and dementia in old age: a prospective study on the effects of exercise, smoking and alcohol consumption.

Previous research has yielded inconsistent results on the effects of exercise, smoking and alcohol use on cognitive impairment and dementia in old age. We analysed data from the Sydney Older Persons Study to see if these health habits were associated with cognitive functioning, dementia or Alzheimer's disease. Health habits were assessed in Wave 1 of the study, when the subjects were aged 75 years or over. Three years later, the subjects were tested for cognitive functioning and clinically examined for dementia and Alzheimer's disease. The analysis was restricted to the 327 subjects examined in Wave 2 who were non-demented in Wave 1. There were few significant associations between health habits and cognitive performance and these were not found consistently across cognitive measures. No associations were found with dementia or Alzheimer's disease. While these health habits do not affect risk for dementia and cognitive impairment in the very elderly, who are at highest risk for these disorders, we cannot discount a role at younger ages.

Oral hygiene habits among adolescents in Finland.

The aim of this study was to analyze oral hygiene habits among Finnish adolescents with regard to age, sex, residence, socioeconomic factors, school career and success. A representative sample of 3209 Finnish adolescents, 13-19 years of age, was drawn. The data were collected by mail surveys in February and September 1977. Participation percentages were 88 and 79. The proportions of daily brushers were 89% in girls and 57% in boys. Toothpicks were used sporadically by every second adolescent but daily by 3% only. Dental floss was used sporadically by 10% of the adolescents but daily by 1% only. In this respect girls were more assiduous than boys. Frequency of toothbrushing clearly increased with age. Girls brushed their teeth significantly more often than boys. The influence of socioeconomic factors was consistent in boys but almost nonexistent in girls. Children of white-collar workers reported better oral hygiene habits than children of blue-collar workers and farmers. Urban adolescents reported better habits than rural adolescents. School success correlated positively with toothbrushing frequency in the younger age groups. Dental health education given by a dentist, a teacher, a hygienist or a nurse had poor correlation with the oral hygiene habits of Finnish adolescents. It was concluded that dental health education should be more directed towards boys, especially at ages 13-15. The education should be planned so that the dental health education better reaches youth of rural areas and lower social classes.
