Prevalence of dental caries and sugar consumption among 6-12-y-old schoolchildren in La Trinidad, Benguet, Philippines.

OBJECTIVE: To determine the prevalence of dental caries and the level of sugar consumption among 6-12-y-old schoolchildren in La Trinidad, Benguet, Philippines. DESIGN: A Cross-sectional study as a baseline survey for a later intervention program. A questionnaire was distributed to obtain information on dental history and total consumption of food with sugar. Caries were diagnosed based on the WHO recommendation. RESULTS: A total of 1200 schoolchildren, aged 6-12 y were included. The prevalence of dental caries in primary dentition was 71.7% and in the permanent dentition, 68.2%. The mean total decayed, extracted due to caries and filled primary teeth (DMFT) and decayed, missing and filled permanent teeth (DMFT) were 4.12 (s.d. 4.03) and 2.40 (s.d. 2.57), respectively. As age increased the mean DMFT increased. Majority (70%) had tooth brushing practices, and less than half (42.5%) had a dental visit only when necessary. Their sugar intake was twice more than the WHO recommendation with a mean daily total intake of 59 g per person. Most common sources of dietary sugar were hard candies (89%), banana cue (84.9%), camote cue (84.9%) and soft drinks (84.4%). No significant correlation was found between sugar intake and dental caries. CONCLUSION: The results indicate that dental caries is highly prevalent and increase with augmented sugar consumption. This maybe due to a widespread neglect of oral health and an increased availability of refined sugary products. Caries rates mirrored those of the developing countries with untreated lesions dominating all ages. The high level of untreated caries in all age groups is a cause for concern.

A tangibly reinforced speech reception threshold procedure for use with small children.

Forty normal-hearing children between 17 and 56 months were tested using a new method for determining speech reception thresholds. The words employed were names for parts of a device that was in the form of a colorful clown. The device automatically rewarded the child with a small piece of candy each time he pressed the part of the clown that had been announced through the sound field system of a speech audiometer. Results showed that operant conditioning speech audiometry using tangible reinforcers is feasible for small children. Both boys and girls can be tested accurately by this method down to age two and one-half years.

Disposition kinetics and effects of menthol.

BACKGROUND: Menthol is widely used in a variety of commercial products and foods, but its clinical pharmacology is not well studied. To determine the disposition kinetics and to examine subjective and cardiovascular effects of menthol, we conducted a crossover placebo-controlled study that compared pure menthol versus placebo, along with an uncontrolled exposure to menthol in food or beverage. A novel assay for the measurement of menthol in biological fluids was also developed. METHODS: Twelve subjects were studied; each received a 100 mg l-menthol capsule, a placebo capsule, and 10 mg menthol in mint candy or mint tea on three different occasions. Plasma and urine levels of menthol and conjugated menthol (glucuronide), cardiovascular measurements, and subjective effects were measured at frequent intervals. RESULTS: Menthol was rapidly metabolized, and only menthol glucuronide could be measured in plasma or urine. The plasma half-life of menthol glucuronide averaged 56.2 minutes (95% confidence interval [CI], 51.0 to 61.5) and 42.6 minutes (95% CI, 32.5 to 52.7) in menthol capsule and mint candy/mint tea conditions, respectively (P < .05). The plasma area under the plasma concentration-time curve ratios for menthol capsule to mint candy/mint tea treatment averaged 9.2 (95% CI, 8.2 to 10.1). Urinary recovery of menthol as the glucuronide averaged 45.6 and 56.6% for menthol capsule and mint candy/tea, respectively (difference not significant). After menthol capsule dosing, the decrease in heart rate was less than the decrease after placebo administration (P < .05). Menthol reduced subjective vigor value at 30 minutes. CONCLUSIONS: We conclude that pure menthol and menthol in food or beverages have a similar systemic bioavailability and that menthol has a small cardioaccelerating effect.

Fatal and near-fatal anaphylactic reactions to food in children and adolescents.

BACKGROUND AND METHODS: Reports of fatal or near-fatal anaphylactic reactions to foods in children and adolescents are rare. We identified six children and adolescents who died of anaphylactic reactions to foods and seven others who nearly died and required intubation. All the cases but one occurred in one of three metropolitan areas over a period of 14 months. Our investigations included a review of emergency medical care reports, medical records, and depositions by witnesses to the events, as well as interviews with parents (and some patients). RESULTS: Of the 13 children and adolescents (age range, 2 to 17 years), 12 had asthma that was well controlled. All had known food allergies, but had unknowingly ingested the foods responsible for the reactions. The reactions were to peanuts (four patients), nuts (six patients), eggs (one patient), and milk (two patients), all of which were contained in foods such as candy, cookies, and pastry. The six patients who died had symptoms within 3 to 30 minutes of the ingestion of the allergen, but only two received epinephrine in the first hour. All the patients who survived had symptoms within 5 minutes of allergen ingestion, and all but one received epinephrine within 30 minutes. The course of anaphylaxis was rapidly progressive and uniphasic in seven patients; biphasic, with a relatively symptom-free interval in three; and protracted in three, requiring intubation for 3 to 21 days. CONCLUSIONS: Dangerous anaphylactic reactions to food occur in children and adolescents. The failure to recognize the severity of these reactions and to administer epinephrine promptly increases the risk of a fatal outcome.

Comb wax mediates the acquisition of nest-mate recognition cues in honey bees.

Honey bees, Apis mellifera, acquire nest-mate recognition cues from wax, the predominant material used in nest construction. Exposure of a newly emerged worker bee to wax-comb substrate significantly reduced the acceptability of that worker to sister bees. Cues acquired from the comb provided colony-specific information about the identity of worker bees; moreover, the effect of comb exposure has been previously shown to override individually produced cues. Food odors (anise oil), when dissolved in paraffin wax, affected worker-recognition characteristics but food odors did not affect these characteristics when fed to bees in sugar candy. Paraffin wax alone did not affect the recognition cues of bees, showing that the wax can be a neutral medium for the transmission of cues. The wax comb in the colony and the hydrocarbon outer layer of the bee cuticle may be a continuous medium for any hydrocarbon-soluble substances used by honey bees in nest-mate recognition; if so, a mechanism by which environmental cues are acquired by honey bees is provided.

Acculturation and dietary habits of Korean Americans.

This is the first study to investigate how food and nutrient intakes vary with the levels of acculturation of Korean Americans using a dietary assessment tool tested for validity and reliability. The respondents were Korean Americans (n 486) resident in the Greater New York metropolitan area, USA. They were divided into two groups according to the total score of acculturation: low- and high-acculturated groups. Using a food-frequency questionnaire and a modified Suinn-Lew Asian self-identity acculturation scale, differences in the frequencies of food items, food groups and nutrient intakes consumed were analysed by level of acculturation. The low-acculturated group tended to consume significantly more rice, mixed rice, soyabean paste chigae (pot stew), saengsun (fish) chigae, kimchi chigae, other fish broiled or baked, eggs, kimchi, spinach, persimmons, and white or brown sugar in coffee or tea. The high-acculturated group demonstrated a statistically greater tendency to consume bread, cereal, spaghetti, ham, green salad, sweetcorn, chocolate, candies and diet soft drinks. The more acculturated an individual, the more significant was the tendency to consume sweets. The more acculturated group had significantly (P<0.05) higher intakes of % energy from total fat, thiamin, vitamin E and folate, while the low-acculturated group consumed greater amounts of Na, niacin and dietary fibre. The information from the present study can be used to describe dietary habits according to various aspects of acculturation, and allows a better understanding of the dynamics of acculturation and dietary habits.

Eat to live or live to eat? Do parents and children agree?

UNLABELLED: The lifestyles and diets of children in developed countries is changing rapidly in response to the social and cultural climate, as well as the availability of an increasing range of foods. The aim of this on-going study is to assess the trends in food-related behaviours of children and their attitudes towards food and nutrition. The study also monitors markers for physical activity, which have been presented elsewhere (Bellisle et al, 2000). Three successive surveys (1993, 1995, and 1997) were carried out on samples of 1000 French children aged 9--11 years and their mothers. RESULTS: Attitudes towards food varied markedly between children and their mothers. Children viewed food primarily as a necessity of life, whereas mothers viewed food primarily as a pleasure for their child, with necessity and nutrition given a lower importance. Contrary to popular belief children's enjoyment of 'unhealthy' and 'healthy' foods was similar. French-fries were the favourite food for 92% of children, closely followed by pasta (89%). Fruit and candy received similar scores (82% and 81% respectively), suggesting that external factors such as convenience are the prime barrier to fruit consumption rather than the enjoyment factor. Over the three surveys a strong persistence of the traditional French meal pattern has been demonstrated, with breakfast, lunch and evening meals eaten by 97%, 96% and 99% of children respectively. One increasing occurrence is the viewing of television during meal times with 25% of breakfasts, 46% of afternoon snacks and 41% of evening meals consumed in front of the television. Children's attitudes towards food demonstrated an overwhelming trust of their mother and her ability to provide them with nourishing foods. Mothers often found it difficult to reconcile the demands of family life, employment, healthy eating and the maintenance of a pleasurable atmosphere at mealtimes. CONCLUSIONS: Overall, children and mothers appeared to have divergent attitudes towards food. An understanding of children's enjoyment of foods considered more 'healthy' or less 'healthy' enables effective nutrition messages to be developed for children. However, further work is needed to explore the long-term impact of mothers' attitudes towards food and mealtimes on a child's relationship to food and eating habits during adolescence through to adulthood.

Secular trends in diet among elderly Swedes -- cohort comparisons over three decades.

OBJECTIVE: The purpose of this study was to compare dietary practices among different birth cohorts of 70-year-old Swedes, who were examined between 1971 and 2000. SETTING: Göteborg, Sweden. DESIGN: Four population-based samples of 1360 70-year-olds, born in 1901, 1911, 1922 and 1930, have undergone health examinations and dietary assessments over a period of almost three decades. One-hour diet history (DH) interviews were conducted in 1971, 1981, 1992 and 2000 with a total of 758 women and 602 women. The formats and contents of the dietary examinations were similar over the years. Statistical analysis of linear trends was conducted, using year of examination as the independent variable, to detect secular trends in food and nutrient intakes across cohorts. RESULTS: At the 2000 examination, the majority of 70-year-olds consumed nutritionally adequate diets. Later-born cohorts consumed more yoghurt, breakfast cereals, fruit, vegetables, chicken, rice and pasta than earlier-born cohorts. Consumption of low-fat spread and milk also increased, along with that of wine, light beer and candy. In contrast, potatoes, cakes and sugar were consumed less in 2000 than in 1971. The ratio of reported energy intake to estimated basal metabolic rate did not show any systematic trend over time in women, but showed a significant upward trend in men. CONCLUSIONS: The diet history method has captured changes in food selections in the elderly without changing in general format over three decades. Dietary quality has improved in a number of ways, and these findings in the elderly are consistent with national food consumption trends in the general population.

Exploring changes in middle-school student lunch consumption after local school food service policy modifications.

OBJECTIVE: This study assessed the impact of changes in school food policy on student lunch consumption in middle schools. METHODS: Two years of lunch food records were collected from students at three middle schools in the Houston, Texas area. During the first year, no changes occurred in the school food environment. After that school year was completed, chips and dessert foods were removed from the snack bars of all schools by the Food Service Director. Students recorded the amount and source of food and beverage items consumed. Point-of-service purchase machines provided a day-by-day electronic data file with food and beverage purchases from the snack bars during the 2-year period. Independent t-tests and time series analyses were used to document the impact of the policy change on consumption and sales data between the two years. RESULTS: In general, student consumption of sweetened beverages declined and milk, calcium, vitamin A, saturated fat and sodium increased after the policy change. Snack chips consumption from the snack bar declined in year 2; however, consumption of snack chips and candy from vending increased and the number of vending machines in study schools doubled during the study period. Ice cream sales increased significantly in year 2. CONCLUSIONS: Policy changes on foods sold in schools can result in changes in student consumption from the targeted environments. However, if all environments do not make similar changes, compensation may occur.

Gender differences in knowledge, attitude, behavior and perceived oral health among adolescents.

A cross-sectional dental questionnaire census survey was conducted in classrooms of 17,280 students aged 13-18 years in Skaraborg County, Sweden. The overall response rate, based on school attendance on the test day, was 91% with no gender differences at the senior level, and 86% (boys 87%, girls 85%) at the upper secondary level. The aim was to examine gender differences in knowledge, attitude, behavior and perceived oral health. A retest study showed good agreement. Thirty-one percent of the girls and 21% of the boys flossed regularly. Eleven percent reported daily candy consumption, with no significant gender difference. Girls, however, more often than boys considered their own consumption to be too high. This gender difference in attitude was most pronounced among older daily consumers (odds ratio (OR) = 5.8 [3.7-9.2]). Oral health was regarded as important by a majority of the students (95%). Girls considered sound teeth to be more important than did boys, both among the younger (OR = 1.7 [1.4-2.1]) and the older (OR = 2.4 [1.9-3.1]) adolescents. It is concluded that most adolescents had a positive dental attitude and perceived their own oral health to be good. Poorer knowledge and behaviors concerning oral health were demonstrated. Gender differences existed in most issues. Girls scored more favorably on behavioral measures, showed more interest in oral health, and perceived their own oral health to be good to a higher degree than did boys.

Analysis of polycyclic aromatic hydrocarbons in cooking oil fumes.

Various samples of cooking oil fumes were analyzed to an effort to study the relationship between the high incidence of pulmonary adenocarcinoma in Chinese women and cooking oil fumes in the kitchen. Polycyclic aromatic hydrocarbons (PAHs) in samples of cooking oil fumes were extracted, chromatographed, and measured by fluorescence spectrophotometer. The samples included oil fumes from three commercial cooking oils and fumes from three catering shops. All samples contained benzo(a)pyrene (BaP) and dibenzo (a,h)anthracene (DBahA). In addition, the concentration of DBahA was 5.7 to 22.8 times higher than that of BaP in the fume samples. Concentrations of BaP and DBahA were, respectively, 0.463 and 5.736 micrograms/g in refined vegetable oil, 0.341 and 3.725 micrograms/g in soybean oil, and 0.305 and 4.565 micrograms/g in vegetable oil. Investigation of PAH concentrations at three catering shops showed that the level of BaP at a Youtiao (deep-fried twisted dough sticks) shop was 4.18 micrograms/100 m3, 2.28 micrograms/100 m3 at a Seqenma (candied fritters) workshop, and 0.49 micrograms/100 m3 at a kitchen of a restaurant; concentrations of DBahA were 33.80, 14.41, and 3.03 micrograms/100 m3, respectively. The high concentration of carcinogens, such as BaP and DBahA, in cooking oil fumes might help explain why Chinese women, who spend more time exposed to cooking oil fumes than men, have a high incidence of pulmonary adenocarcinoma.

The importance of social context in cross-cultural comparisons: first graders in Colombia and the United States.

The authors explored the cultural constructs of individualism and collectivism by investigating the prosocial behavior of 1st graders (N = 202; 110 girls, 92 boys) in countries typically classified as collectivist (Colombia, South America) and individualist (United States). Contrary to expectations, U.S. children shared more than Colombian children did. However, U.S. children were more likely to take candy from another child without permission (demonstrating individualism). Results indicated that in both countries sharing was greater with friends than with other fellow classmates, and children frequently reported friendship as the reason they shared. Findings support the importance of the social context, such as the relationship between participants, in cross-cultural research and suggest that simple dichotomies of culture often overlook complex associations between culture and behavioral differences.

Mood and helping.

In order to test (a) whether helping someone puts the helper in a better mood and (b) whether people in a good mood are more likely than controls to help with a task maintaining their positive mood but no more likely to help with a task leading to a negative mood, 80 female undergraduates participated in a study in which they (a) had an interaction with a confederate (C) designed to put them in a good or neutral mood, (b) rated their mood, (c) rated some neutral pictures, and (d) were requested to rate some potentially elating or depressing pictures. Ss who were induced to help C or who were given candy by her rated themselves as feeling nicer than these having a more neutral interaction. Neither their interaction with C, the type of pictures they were ased to rate, nor their self-reported mood, with the exception of happiness, was significantly associated with number of pictures rated or time spent helping. Those rating the depressing pictures became more depressed than those rating the cheerful pictures. It was suggested that the lack of significant findings might be due either to the fact that the effect of a good mood on helping declines over time or to the fact that rating pictures was so enjoyable that it was not considered altruistic.

Cognitive organization of favorable and unfavorable beliefs about performing a behavior.

Intentions to perform behaviors are influenced by beliefs about their consequences, but researchers have not addressed how such beliefs are cognitively organized. In 3 experiments, the authors tested the hypothesis that beliefs are organized according to whether they are favorable or unfavorable in regard to performing a behavior. In Experiment 1, a group of U.S. students first read a list of beliefs favorable and unfavorable to going to a vacation resort and then listed their beliefs about condom use. In Experiment 2, another group of U.S. students listed their beliefs about condom use. In Experiment 3, a 3rd group of U.S. students listed their beliefs about a novel behavior (asking the experimenter for candy). The results of all 3 experiments were consistent with the hypothesis that people cognitively organize their beliefs according to whether they are favorable or unfavorable to the behavior in question.

Analysis of acrylamide by LC-MS/MS and GC-MS in processed Japanese foods.

Acrylamide concentrations in processed foods (63 samples covering 31 product types) from Japan were analysed by LC-MS/MS and GC-MS methods. The limit of detection and limit of quantification of acrylamide were 0.2 ng x ml(-1) (6 fmol) and 0.8 ng x ml(-1) (22 fmol), respectively, by LC-MS/MS, and those of 2,3-dibromopropionamide derived from acrylamide were 12 ng x ml(-1) (52 fmol) and 40 ng x ml(-1) (170 fmol), respectively, by GC-MS. Repeatability given as RSD was <5 and <15% for the LC-MS/MS and GC-MS methods, respectively. High correlation (r(2) - 0.946) was observed between values obtained by the two methods. Most potato crisps and whole potato-based fried snacks showed acrylamide concentrations >1000 microg x kg(-1). The concentrations in non-whole potato-based snacks, rice crackers processed by grilling or frying, and candied sweet potatoes were lower compared with those in the potato crisps and the whole potato-based fried snacks. One of the whole potato-based fried snacks, however, showed low acrylamide concentration (<50 microg x kg(-1)) suggesting the formation of acrylamide is strongly influenced by processing conditions. Acrylamide concentrations in instant precooked noodles and won-tons were <100 microg x kg(-1) with only one exception. Roasted barley grains for 'Mugi-cha' tea contained 200-600 microg x kg(-1) acrylamide.

Analysis of pulegone and its enanthiomeric distribution in mint-flavoured food products.

A procedure for the extraction and determination of pulegone enanthiomers in mint essential oils and mint products (syrups, dried leaves, toothpaste, lozenges, candy and chewing-gum) was developed. The compounds were recovered from the food matrices by employing a simultaneous distillation-extraction (SDE) technique with a Likens-Nickerson apparatus using dichloromethane as an extraction solvent. The analyses were performed by capillary gas chromatography mass spectrometry (GC/MS). Experiments on food products spiked at different pulegone concentrations showed recoveries ranging from 95 to 106%. The detection limit was about 5?mg?l(-1) for both pulegone enanthiomers and good linearity was found in the concentration range 0.5-25?mg?l(-1). In a number of repeated analyses, the pulegone peak height repeatability (RSD) was 0.2%. The pulegone enanthiomers were separated and quantified by enanthioselective multidimensional gas chromatography. The results of analyses conducted on essential mint oils and mint-flavoured food products are reported.

Mutagenic investigation of flavourings: dimethyl succinate, ethyl pyruvate and aconitic acid are negative in the Salmonella/mammalian-microsome test.

Three flavourings: dimethyl succinate, ethyl pyruvate and aconitic acid, commonly used in candy, beverages, and baked goods, were tested in the Salmonella/mammalian-microsome test. Tester strains were TA 1535, TA 100, TA 1537 and TA 98 and doses were 32, 160, 800, 4000 and 20 000 micrograms per plate. All tests were performed with and without the S9 fraction from Aroclor induced rat liver. None of the flavourings showed mutagenic potential. These results support the classification made by the Council of Europe, List I (1981).

Potential weekly intake of artificial food colours by 3-14-year-old children in Brazil.

The Potential Weekly Intake (PWI) of artificial food colours by 3-14-year-old children living in the District of Barão Geraldo, Campinas, São Paulo, Brazil, was estimated on the basis of average consumption data of artificially coloured food and analytically determined colour concentration in foodstuffs ingested. Coloured food consumption data were obtained through dietary recall interviews and collection of the packages and/or labels of the coloured foods consumed during a two-week period. Colours found in the individual types of foods detected through the consumption survey were identified and determined by methods that included wool dyeing and polyamide column extractions, ascending paper chromatography and spectrophotometry. The results showed that all artificial colours used in the composition of 83 commercial food products, including jellies, juices, soft drinks, syrups and 57 different candies, were permitted for use in food in Brazil the year the survey was conducted (1986), in amounts below those prescribed by law. Statistical analysis performed to compare the PWI for different population groups demonstrated that young male children, especially from lower social classes, were most exposed to artificial colours. Comparison of the estimated potential intakes with the toxicologically Acceptable Daily Intake (ADI) showed that consumption of Amaranth, Sunset Yellow, Indigotine and Tartrazine by all children in the study represented approximately 24%, 3%, 0.05% and 0.4%, of the actual ADI values, respectively.
